Description

a device for attaching a carrier to a traction cable, a vehicle equipped with the device, and a towing cable transportation device including the carrier

The present invention relates to the attachment of a carrier to a towing cable and, more particularly, to a towing cable transport apparatus.

Currently, a vehicle that is towed by a cable, whether overhead or on the ground, includes fasteners for attaching the carrier to the traction cable. When the fasteners are permanently attached to the traction cable, the fasteners are said to be fixed. The securing fastener can be a fixed clamp that secures the traction cable to a position in which the travel path of the cable through the carrier remains constant. There is another type of fastening fastener that includes two plates that are riveted to each other, and between the two plates, one of the traction cables is turned in a V-shaped curve, also known as a "cocked hat". . However, such fixed fasteners do not increase the passenger transport rate because the traction cable must be stopped to secure the carrier so that the passenger can access the download.

Other fasteners are said to be separable, in which case the fasteners removably couple the carrier to the traction cable. For example, a city transportation system with ground cable traction can be cited that includes a detachable clamp to secure or release the moving traction cable. But traction cable The speed is not very high, about 15km/h, and does not provide high transport rates. Additionally, when stationary, the carrier is coupled to the traction cable. Therefore, when the clamp fastens the cable, there is a large amount of friction between the cable and the detachable clamp, causing undue wear of the clamp and the traction cable. In addition, in the event of an accident in the vehicle, the carrier can be fixed to the line while the traction cable remains moving, which can result in a risk of collision with a later carrier.

It is also possible to cite a detachable transport system with an overhead traction cable, such as a chair lift or an aerial cable car. In such cases, when in the terminal or intermediate station, the carrier is uncoupled from the traction cable to move the carrier at a reduced speed to assist the passengers up and down, while at the same time making the traction cable The drive is maintained at a higher constant speed. However, the station must be equipped with a start and deceleration section of the vehicle to close and open the detachable clamps respectively when the carrier and the traction cable are at the same speed to avoid damage to the fixture. These sections are typically long and their length is additionally proportional to the drive speed of the traction cable. Therefore, when it is desired to increase the driving speed of the traction cable (specifically, increasing the passenger transportation rate), the length of such segments must be increased. Additionally, such sections are complex because they are equipped with a starter and reducer equipped with a motor-driven alignment tire and are equipped with a synchronization system that is used to adjust the speed of the tire to the speed of the traction cable.

A further patent application FR 2719011, which discloses a carrier transport device equipped with two track rails and a traction cable, wherein each carrier is equipped with wheels placed on the rails and used to connect the vehicles to the traction A detachable clamp for the cable. The carrier further includes an electric motor powered by a rechargeable battery that drives the wheel to accelerate the carrier via the acceleration section to achieve the speed of travel of the traction cable. However, the vehicle must be equipped with a complex adjustment and control unit that must perform the synchronization of the speed of the vehicle with the speed of the cable. In particular, the unit must control the start and acceleration of the vehicle. The transport equipment must additionally be equipped with rail or carrier cables in order to be able to accelerate the vehicle.

A further reference is made to the French patent application FR3013298, which discloses a device for attaching a carrier to two overhead traction cables, the device comprising a first means for removably fastening the carrier to a first speed A first fastener of the traction cable and a second fastener for releasably securing the carrier to a second traction cable that is driven at a second speed lower than the first speed. The first fastener comprises: a main pulley designed to suspend and guide the carrier on the first cable; and two lateral intermediate pulleys disposed on each side of the main pulley and fixed on the carrier The first position to the first cable moves between the second position in which the carrier is separated from the first cable. The second fastener comprises: a main pulley designed to suspend and guide the carrier on the second cable; and an intermediate pulley disposed facing the main pulley and fixed to the second cable at the carrier The first position moves between a second position in which the carrier is separated from the second cable. The first and second fasteners further include a progressive engagement member configured to manage the gradual force of the force securing the other fastener to the traction cable while releasing one of the two fasteners. However, such attachment devices are not suitable for equipment equipped with a single traction cable, whether it is overhead or on the ground. In effect, the first fastener cooperates with the first traction cable and the second fastener cooperates with the second traction cable, each traction cable serving as a support structure for the device. Such devices must therefore be equipped with two traction cables having different speeds, which makes achieving such devices significantly more complicated. In addition, the progressive engagement member is complicated because it is necessary to simultaneously open the other fastener during closing of a fastener to prevent rotation of the carrier itself, and to have a greater speed in releasing the fastening of the second fastener. In the case where the first fastener of the first cable is fastened to the second cable, the possible tearing of the first fastener is prevented.

Purpose of the invention

It is an object of the present invention to remedy these disadvantages and, more particularly, to In other words, components for simplifying the traction cable transport device are provided by minimizing the length of the terminal stations of such devices.

Accordingly, a coupling device is provided that enables the speed of the carrier to be modified while maintaining a constant speed of one of the traction cables. In effect, the rotation of the rotating elements enables the carrier to move relative to the traction cable while maintaining the carrier coupled to the traction cable, i.e., maintaining the fastener mechanically coupled to the traction cable . In addition, the speed of the rotating elements can be modified when the carrier is coupled to the traction cable so that the carrier can be decelerated until the carrier is stopped, or the carrier is driven from the cable in the direction of travel of the cable. One position does not move to accelerate. Therefore, it is no longer necessary to equip the station of the equipment with the long and complicated acceleration and deceleration sections of the vehicle. Additionally, when the rotating elements have a lower speed than the speed of the traction cable, the carrier remains pulled by the traction cable.

The adjustment member can be further configured to prevent rotation of the at least two rotating elements when the at least two rotating elements are in the engaged position such that the carrier is stationary relative to the traction cable.

Such devices are particularly well suited for use in cable transport equipment that secures the transport of such vehicles using a support structure. The wheel of the carriage facilitates movement of the carrier relative to the traction cable when the adjustment member modifies the rotational speed of the rotating elements.

The variable speed drive may include two cones connected from the top to the end and coupled to the input shaft and the output shaft, respectively, and a transmission belt connected to the two cones, the control unit configured to move the transmission belt In order to control the rotational speed of the at least two rotating elements.

The at least one rotating element is mounted for translational movement between the attachment position of the carrier coupled to the traction cable and an uncoupling position of the carrier from the traction cable.

A fastener of the separable type is therefore provided.

The fastener includes a housing for receiving the traction cable, the housing extending along a major axis, the device including a guide along the main axis when the at least two rotating elements are in the coupled position A member to retain the traction cable in the outer casing.

The guiding members are particularly suitable for facilitating travel over the tower of the apparatus, and are particularly adapted to retain the traction cable in the housing.

The apparatus can further include a detachable clamp configured to removably couple the carrier to the traction cable.

Such a clamp enables the carrier to be attached to the traction cable to be reinforced, in particular in the level of the portion of the traction cable that is inclined relative to the horizontal level, to stabilize the traction of the carrier.

The apparatus can include an actuator for driving the at least one rotating element to rotate when the at least one rotating element is in the uncoupling position.

In Fig. 1, an embodiment of a transport device 1 for pulling a cable 2 is presented. The device 1 comprises carriers 3 to 5 designed to be attached to a traction cable 2, which are towed for transporting people or goods. The device 1 can be any type of cable car (for example a single cable or a double cable type). The cable car is a transport device with overhead traction cables and carrier cables, and the vehicles are suspended above the ground by means of overhead cables. The single cable car 1 includes at least one cable 2 as both a carrier and a traction cable, and the twin cable car 1 includes at least one traction cable 2 and at least one carrier cable 6. Transport equipment 1 also A traction cable 2 positioned on the ground and a support structure comprising one or more support rails 6, 7 on which the carriers 3 to 5 are placed may be included. As a variant, the device 1 may comprise at least one overhead traction cable and support structures 6, 7 designed to support the carriers 3 to 5. According to this alternative embodiment, the support structure comprises one or more carrier cables 6, 7, and it is also said that the carriers 3 to 5 are suspended from the carrier cables 6, 7.

Preferably, the device 1 is of a separable type, i.e., the carriers 3 to 5 are uncoupled from the traction cable 2. "Unlinking" means that the carriers 3 to 5 are not mechanically connected to the traction cable 2 (in other words, the carriers 3 to 5 are not in mechanical contact with the traction cable 2). In contrast, "link" means that the carriers 3 to 5 are mechanically connected to the traction cable (ie, the carriers 3 to 5 are in mechanical contact with the traction cable 2). Advantageously, the device 1 has a continuous traction cable, in other words, the traction cable 2 forms a closed loop between the two terminal stations 8, 9 of the device 1, and the carriers 3 to 5 continuously travel along the traction cable 2 . In Fig. 1, an embodiment of a device 1 is presented in which the device 1 is detachable, has a double cable and has a continuous traction cable 2. The device 1 further comprises one or more intermediate stations 10, and the stations 8 to 10 are suitable for people on/downloading tools 3 to 5. More specifically, the apparatus 1 includes a drive station 9 equipped with a motor 11 to drive the drive pulley 12 to rotate, drive the traction cable 2 in the moving direction Y, and a return pulley 13 for the purpose of tensioning the traction cable 2. Return to station 8. Each of the carriers 3 to 5 further includes a compartment 14 that can be a compartment designed to accommodate a passenger or a container designed to receive merchandise (eg, waste).

In addition, at least one of the carriers 3 to 5 includes a coupling device 15 for coupling the carriers 3 to 5 to the traction cable 2. In Figures 2 to 9, several embodiments of the coupling device 15 are illustrated. In general, the attachment device 15 includes a fastener 16 that is configured to couple the carriers 3-5 to the traction cable 2. The fastener 16 comprises at least two rotating elements 17 to 20, that is, mounted for rotation Turn the moving component. The rotating elements 17 to 20 are configured to occupy their joint position F with the traction cable 2 and the carriers 3 to 5 are coupled to the traction cable 2. In the joint position F, the rotary elements 17 to 20 are attached to the traction cable, that is, they apply a fastening pressure to the traction cable 2. The tightening pressure is such that the traction cable 2 can pull the minimum pressure of the carriers 3 to 5. In addition, when the apparatus 1 includes a single overhead cable 2 as both a traction cable and a carrier, the fastening pressure is sufficient to draw and suspend the carriers 3 to 5 by the cable 2. In this case, the carriers 3 to 5 can be suspended without having to equip the device 1 with the support structures 6, 7 different from the traction cable 2.

The fastener 16 can comprise a number of rotating elements 17 to 20. In Figures 6 and 7, the fastener 16 comprises two rotating elements 17, 18. In Figures 8 and 9, the fastener 16 comprises three rotating elements 17 to 19. In Figures 1 to 5, a preferred embodiment is presented in which the fastener 16 comprises four rotating elements 17 to 20. The rotating elements 17 to 20 may comprise at least one sheave, referred to as a stop sheave, which is mounted to be Rotate the movement. The sheave is prevented from being a cylindrical or conical wheel. The stop sheave may be provided with a recess for pulling the cable 2 to facilitate preventing contact of the sheave with the traction cable 2. More specifically, each of the blocking sheaves 17 to 20 of the fastener 16 is mounted to be rotationally movable about an axis passing through the center thereof. According to another example, the rotating elements 17 to 20 may comprise at least one stop sheave and a belt designed to fit between the traction cable 2 and at least one of the rotating elements 17 to 20 to prevent the sheave. When the sheave is prevented from contacting the belt and is also driven to rotate, the belt can then be translated in translation along the drive direction Y of the traction cable 2. In this example, the rotating elements 17 to 20 form a track.

The fastener 16 can be configured to secure the carriers 3 to 5 to the traction cable 2 in a fixed manner, as illustrated in Figures 6 and 8. It is also said that the fastener 16 is fixed. In this case, the rotating elements 17 to 20 were previously disposed inside the fastener 16 such that the rotating elements 17 to 20 are in contact with the traction cable 2 to connect the carriers 3 to 5 to the traction cable 2. In particular, the vehicle is 3 to 5 Connect to cable 2 in a permanent location. According to another embodiment, the fastener 16 can be configured to removably couple the carriers 3 to 5 to the traction cable 2, as illustrated in Figures 1-9. The fastener 16 is also said to be separable. In this case, the at least one rotating element 17 to 20 is mounted to the joint position F (where the carriers 3 to 5 are coupled to the traction cable 2) as illustrated in FIGS. 2, 6 and 8 and in FIG. The translational position O (where the carriers 3 to 5 are uncoupled from the traction cable 2) illustrated in FIGS. 7 and 9 is translated. Each of the rotating elements 17 to 20 can be mounted for translational movement. In particular, in the uncoupling position O, the rotating elements 17 to 20 are no longer in contact with the traction cable 2, and the traction cable 2 can be withdrawn from the fastener 16 or inserted into the fastener 16. In other words, the uncoupling position O of the rotating elements 17 to 20 corresponds to the open position O of the fastener 16, and the joint position F of the rotating elements 17 to 20 corresponds to the closed position F of the fastener 16. Regardless of the type of fastener 16 (whether fixed or detachable), the joint position F is the same. That is, in the joint position F, the rotary elements 17 to 20 are positioned in contact with the traction cable 2 such that the rotary elements 17 to 20 are attached to the traction cable 2. When the rotating elements 17 to 20 are attached to the traction cable 2, the carriers 3 to 5 are said to be coupled to the traction cable 2. More specifically, in the joint position F, the rotary members 17 to 20 are not moved in translation relative to the fastener 16. In the joint position F, the rotary members 17 to 20 can be rotationally moved or not rotated while maintaining the tightening pressure on the traction cable 2. For example, the attachment device 15 can include an adhesive member 23 configured to place the rotating elements 17-20 in the joint position F. The adhesive member 23 is further configured to apply a fastening pressure against the traction cable 2 to the at least one rotating element 17 to 20 such that the rotating elements 17 to 20 are attached to the traction cable 2. It is also noted that when the rotating members 17 to 20 are attached to the cable 2, the fastener 16 is fixed to the traction cable 2.

In general, the fastener 16 includes a housing 21 to receive the traction cable 2. Housing 21 It preferably has a longitudinal shape, that is, it extends along the main axis 22. In other words, the main axis 22 corresponds to the longitudinal axis of the outer casing 21 of the fastener 16. Additionally, the rotating elements 17-20 are positioned on each side of the fastener 16, i.e., on each side of the main axis 22. In the joint position F, the rotary elements 17 to 20 are positioned on each side of the traction cable 2, i.e., the rotary elements 17 to 20 are in contact with the traction cable 2 on two different sides of the cable. In the joint position F, the rotating elements 17 to 20 cooperate with each other to fasten the cable 2 to connect the carrier to the cable 2. In Figures 6 and 7, an embodiment of a fastener 16 is presented that includes two stop sheaves 17, 18 formed in a pair and positioned on each side of the main axis 22 of the outer casing 21. In FIG. 6, the rotating elements 17 to 20 are in the joint position F and they contact the traction cable 2 on the two opposite sides of the traction cable 2. In Figures 8 and 9, another embodiment of a fastener 16 is presented that includes three stop sheaves 17 through 19. The first stop sheave 18 is positioned on one side of the main axis 22, i.e., at the level of the first edge of the outer casing 21, and the two other retaining sheaves 17, 19 are positioned on the other side of the main axis 22. Upper, that is, positioned at the level of the second edge of the outer casing 21 opposite the first edge. In this case, the three sets of the prevention sheaves 17 to 19 form two pairs of the prevention sheaves. In Figures 2 to 5, a preferred embodiment of the attachment device 15 is presented in which the fastener 16 comprises four stop sheaves 17 to 20. In the preferred embodiment, the four sets of stop sheaves 17-20 also form two pairs of stop sheaves. Therefore, by increasing the number of the prevention sheaves 17 to 20, when the sheave is prevented from being in the joint position F, the force to be provided on the prevention sheave to secure the traction cable 2 is restricted. The enhanced safety of suspending the carriers 3 to 5 to the traction cable 2 can then be ensured. Advantageously, the rotating elements 17 to 20 are positioned in the same plane as the plane containing the main axis 22. In addition, when the rotating members 17 to 20 are the blocking sheaves, they are mounted to be rotationally movable about their central axes. The central axis of the chutes 17 to 20 is prevented from passing through the center of the chute and extending along the height of the chute. In particular, the central axis is positioned perpendicular to the main axis 22. In other words, resistance The central axis of the sprocket wheel is perpendicular to the direction of movement of the carriers 3 to 5.

When the fastener 16 is detachable, and regardless of the number of rotating elements 17 to 20, the fastener 16 includes at least one rotating element 17-20 that is mounted for translational movement along the translational axis T to open or close the fastener 16. According to a preferred embodiment, all of the rotating elements 17 to 20 are mounted for translational movement along the translational axis T. Preferably, the translation axis T is perpendicular to the main axis 22 of the outer casing 21. Advantageously, the translation axis T is contained in the plane in which the rotary elements 17 to 20 are positioned.

In general, when the rotating elements 17 to 20 occupy the joint position F and the traction cable 2 is moving, the rotating elements 17 to 20 are configured to be driven to rotate, or not to rotate. When the rotating elements 17 to 20 are in contact with the traction cable 2, the rotation of the rotating elements 17 to 20 additionally prevents the traction cable 2 and the rotating elements 17 to 20 from being worn. In addition, there is very little slippage between the traction cable 2 and the rotating elements 17 to 20, and thus little wear. According to the embodiment illustrated in Figures 6 and 7, when the two blocking sheaves 17, 18 are in the joining position F, the two blocking sheaves apply a fastening pressure to a portion of the traction cable 2. This portion of the traction cable 2 is rectilinear in the outer casing 21 and extends longitudinally along the main axis 22. According to another embodiment illustrated in FIGS. 8 and 9, when the sheaves 17 to 19 are prevented from being in the joint position F, a portion of the traction cable 2 is turned inside the fastener 16. The two pairs of blocking sheaves 17 to 19 apply a fastening pressure to a portion of the traction cable 2. This portion of the traction cable 2 is then turned inside the outer casing 21 (i.e., inside the fastener 16). This steering prevents untimely sliding of the traction cable 2 that may occur when the portion of the cable 2 is straight. According to the preferred embodiment illustrated in Figures 2 to 5, when the sheaves 17 to 20 are prevented from being in the joint position F, a portion of the traction cable 2 is turned inside the fastener 16. The two pairs of blocking sheaves 17 to 20 are applied to one of the traction cables 2 at two successive positions of the traction cable 2, and more particularly at the level of four distinct contact areas on the traction cable 2. Tightening pressure. Therefore, reduce the application The force applied to the portion of the traction cable 2. In general, the rotating elements 17-20 are positioned inside the fastener 16 such that in the joint position F, the end of the portion of the traction cable 2, whether or not turned, is aligned along the main axis 22 of the outer casing 21.

In order to provide the detachable fastener 16, the adhesive member 23 is further configured to translate the rotating elements 17-20. Preferably, the translation of the rotating elements 17 to 20 is performed in a manner parallel to the translational axis T, i.e., to open or close the fastener 16. The adhesive member 23 can include a lever and an actuator coupled to the lever, which is not presented for simplicity. The actuator enables the first set of rotating elements 17, 20 to translate in a first direction T1 of the translation axis T and enables the second set of rotating elements 18, 19 to be in a second direction opposite the first direction T1 along the translation axis T T2 translates to place the rotating elements 17 to 20 in the uncoupling position O and in the opposite way to place the rotating elements 17 to 20 in the joint position F. The actuator may comprise a set of springs, each spring being coupled to the rotating elements 17 to 20 and controlled by a lever. Additionally, when the fasteners 16 are detachable, the terminal stations 8, 9 each include an opening system (e.g., opening the cam 24) for controlling the opening of the fasteners 16, and a closing system for controlling the closure of the fasteners 16 (e.g., The cam 25) is closed, as illustrated in FIG. The opening cam 24 and the closing cam 25 cooperate with the lever to trigger the opening and closing of the fastener 16, respectively. The open cam 24 is placed at the entrance of the terminal stations 8, 9 to swing the lever and trigger the opening of the fastener 16. The closing cam 25 is positioned at the exit of the terminal stations 8, 9 to return the moving lever to the initial position and close the fastener 16.

The joining device 15 also includes an adjusting member 31 configured to modify the rotational speed Vg of the rotating member when the rotating members 17 to 20 are in the joint position F. In other words, when the rotating members 17 to 20 are in the joint position F, the regulating member 31 enables the rotation of the rotating members 17 to 20 to be driven or prevented from rotating. In general, the adjustment member 31 is configured to apply friction to the spin The elements 17 to 20 are rotated to slow their rotation, or even to prevent them from rotating, or to reduce the frictional force to increase the rotational speed of the rotating elements 17 to 20. In particular, when the regulating member 31 reduces the frictional force on the rotating members 17 to 20, the traction cable 2 drives the rotating members 17 to 20 to rotate. The adjustment member 31 can include a variable speed drive coupled to the at least one rotating element 17-20. The variable speed drive can be, for example, a brake, a clutch or a gearbox. When the rotational speed Vg of the rotary elements 17 to 20 is modified and the carriers 3 to 5 are coupled to the traction cable 2, the carriers 3 to 5 can then be moved relative to the traction cable 2. In this case, the carriers 3 to 5 may have a speed different from the traveling speed Vc of the traction cable 2. Specifically, when the rotational speed Vg of the rotary elements 17 to 20 is zero, the rotary elements 17 to 20 are not rotated, and the carriers 3 to 5 are stationary with respect to the traction cable 2, and the traction cable 2 is constantly traveling. The speed Vc moves. In this case, the speed of the carriers 3 to 5 is equal to the speed of the traction cable 2. When the rotational speed Vg of the rotary elements 17 to 20 increases, the speed of the carriers 3 to 5 becomes lower than the traveling speed Vc, and in this case, the carrier is decelerated with respect to the apparatus 1.

Advantageously, the attachment means 15 comprises a bracket 26 on which the fastener 16 is mounted. The bracket 26 is particularly suitable for the device 1 equipped with support structures 6, 7 and having overhead cables or cables positioned on the ground. Bracket 26 includes wheels 27 through 30 that are positioned on each side of bracket 26. The wheels 27 to 30 of the bracket 26 are designed to travel on the support structures 6, 7 of the device 1. The linking device 15 preferably includes a controlled variable speed drive and a speed drive control unit 32 coupled to the controlled variable speed drive by means of a connector 33. The control unit 32 enables the rotational speed Vg of the rotary elements 17 to 20 to be controlled when the rotary elements 17 to 20 are in the joint position F. For example, the bracket 26 can include four drive wheels 27 through 30, that is, four wheels coupled to a variable speed drive. Preferably, the bracket 26 includes two free wheels 27, 28 and two drive wheels 29, 30. The variable speed drive includes an input shaft 34 coupled to the at least one rotating element 17 to 20 and coupled to the input The shaft 34 is coupled to the output shaft 35 of at least one of the wheels 27 to 30 of the carriage 26. The variable speed drive can be a mechanical speed drive, such as a variable speed drive with a cone, an annular variable speed drive, or a chain driven variable speed drive. The variable speed drive can also be a variable speed drive with electric, hydraulic or pneumatic components. The annular variable speed drive includes a drive plate driven by the input shaft 34, a driven plate that drives the output shaft 35, and a movable sheave coupled to the disk to transfer speed from one shaft to the other. The chain drive variable speed drive also includes a drive plate and a driven plate, wherein the transmission of the link is engaged in the groove of the disk engaged by the disk. In general, the variable speed drive allows the gear ratio between the output shaft 35 and the input shaft 34 to vary. In other words, the variable speed drive allows the speed of the input shaft 34 to be varied, that is, the rotational speed of the rotary members 17 to 20 is varied to vary the rotational speed Vr of the drive wheels 29, 30 of the carriage 26. The adjustment member 31 thereby enables the carriage 26 to accelerate or decelerate at any point of the path of the carriers 3 to 5 while maintaining the constant travel speed of the traction cable 2.

In Figures 2 and 3, an embodiment is presented in which the adjustment member 31 comprises a variable speed drive having a cone. The fastener 16 further includes four blocking sheaves 17 to 20. The variable speed drive includes a first cone 36, a second cone 37 and a conveyor belt 38 connected to the two cones 36,37. The variable speed drive may include a fork 39 for moving the conveyor belt 38 to modify the rotational speed Vg of the rotating element. The variable speed drive machine further includes a pinion gear 40 mounted to be fixed to one end of the input shaft 34, and a drive pulley 41 mounted to be fixed to one end of the output shaft 35. The fastener 16 can further include a drive belt 42 that blocks the sheaves 17-20. The drive belt 42 connects the prevention sheaves 17 to 20 to each other by means of drive pulleys 43 respectively mounted on the prevention sheaves 17 to 20. The fastener 16 further includes a toothed wheel 44 coupled to the at least one stop sheave 17 to 20 by means of a drive belt 42. Therefore, when the chutes 17 to 20 are prevented from being driven into a rotation In turn, it drives the toothed wheel 44 and vice versa. The pinion 40 meshes with the toothed wheel 44 of the fastener 16. The drive pulley 41 is coupled to the drive wheels 29, 30 of the carriage 26 in part by means of a drive belt 45 of the wheel of the carriage 26 and a drive pulley 46 of the carriage 26. The drive pulleys 46 of the brackets 26 are coupled to the drive wheels 29, 30, respectively. The cones 36, 37 of the variable speed drive are additionally arranged in a top-to-tail manner, i.e., the second cone 37 is inverted 180° relative to the first cone 36. Each of the cones 36, 37 includes a base and a peak. The base of the first cone 36 is coupled to the input shaft 34 and the base of the second cone 37 is coupled to the output shaft 35.

Control unit 32 is further configured to control the variable speed drive to vary the rotational speed Vg of the rotating elements 17-20. According to the embodiment illustrated in Figures 2 and 3, the control unit 32 controls the position of the fork 39 to control the position of the conveyor belt 38. In other words, control unit 32 controls the position of transmission belt 38 to modify the speed ratio of the variable speed drive. Modifying the position of the conveyor belt 38 enables modification of the speed of the first cone 36 or the second cone 37, that is, the speed of the output shaft 35 or the input shaft 34.

The variable speed drive imposes a speed rule of the input shaft 34 and the output shaft 35 according to the following equation: Vte + Vts = Vc, where Vte is the tangential speed of the input shaft 34 and Vts is the tangential speed of the output shaft 35, and Vc is the travel speed of the traction cable 2. The tangential velocity of a component means the rotational speed of the component multiplied by the radius of the component. The input shaft 34 is coupled to the rotating elements 17 to 20, which can be driven by the rotation of the rotating elements 17-20. The output shaft 35 is coupled to the drive wheels 29, 30 of the carriage 26, and the output shaft 35 drives the wheels 29, 30 to rotate. In general, the adjustment member 31 also imposes the following equation: Vtg + Vtr = Vc, where Vtg is the tangential velocity of the rotating elements 17 to 20, Vtr is the tangential velocity of the wheel of the carrier 26, and Vc is the traction cable 2 travel speed. In particular, we have the following equation: Vtg=Rg×Vg; Vtr=Rr×Vr; wherein: Vtg: tangential velocity of the rotating elements 17 to 20; Rg: radius of the rotating elements 17 to 20; Vg: rotational speed of the rotating elements 17 to 20 having the radius Rg Vtr: the tangential speed of the wheels 27 to 30 of the bracket 26; Rr: the radius of the wheels 27 to 30 of the bracket 26; Vr: the rotational speed of the wheels 27 to 30 having the radius Rr.

It can be noted that when the rotary members 17 to 20 are in the joint position F, all of them have the same tangential speed Vtg, and the wheels 27 to 30 of the carriage all have the same tangential speed Vtr.

When the fork member 39 is in the position C, we have Vtr=0 and Vtg=Vc, the rotating element is driven to rotate by the traction cable 2, the tangential speed Vtg of the rotating element is equal to the speed of the cable 2, and the carriers 3 to 5 Do not move. When the fork member 39 is in the position B, Vtg + Vtr = Vc, preventing the sheaves 17 to 20 from being driven to rotate by the traction cable 2, preventing the tangential speed Vtg of the sheaves 17 to 20 from being lower than the tangential speed of the cable 2. And the carriers 3 to 5 are pulled by the traction cable 2 at a speed lower than the speed Vc of the cable. When the fork member 39 is in the position A, we have Vtg = 0 and Vtr = Vc, preventing the sheaves 17 to 20 from rotating, and the carriers 3 to 5 being pulled at the speed Vc of the traction cable.

In Figure 1, the carriers 3 to 5 have been presented in three different locations in the device 1. The first carrier 3 is positioned in the return station 8, wherein the first carrier 3 travels in the curved loop C1 of the return station 8. The other terminal 9 also contains a curved loop C2. The carrier 3 is also said to be detached, that is, it is uncoupled from the traction cable 2. In this case, the fastener 16 is in the open position O and the carrier 3 Separated from the traction cable 2. The carrier 3 thus unfastens the latch from the traction cable 2 to travel around the return pulley 13 and then reattach to the traction cable 2. The second carrier 4 is positioned between the two terminals 8, 9. The fastener 16 of the second carrier is in the closed position F, the rotary elements 17 to 20 are not rotated, and the carrier 4 is pulled by the traction cable 2 at the travel speed Vc of the cable 2. The third carrier 5 is positioned in the intermediate station 10, which is in a position that is stationary relative to the device 1, that is, docked in the intermediate station 10. In this very specific fixed position, the rotary elements 17 to 20 of the third carrier 5 are in the joint position F, the rotary elements 17 to 20 thus being in contact with the traction cable 2 and being driven to rotate by the traction cable 2. The third carrier 5 is therefore stationary and attached to the traction cable 2, while the traction cable 2 is in motion.

When the variable speed drive is a cone speed drive, the control unit 32 controls the speed of the rotating elements 17 to 20 by moving the conveyor belt 38 between position C and position A, and vice versa. In particular, when the conveyor belt 38 moves from position C to position A, the vehicle accelerates, and in the opposite manner, when the conveyor belt 38 moves from position A to position C, the vehicle decelerates. That is, as the conveyor belt 38 moves from position C to position A, the tangential velocity Vtg of the rotating element decreases, and the tangential velocity Vtr of the wheel of the carriage increases, thereby enabling the carrier to follow the support structure 6, 7 The speed Vc of the traction cable is advanced and progressively reached.

When the carrier is towed at the speed Vc of the traction cable, the rotating elements 17 to 20 are in contact with the traction cable 2 and are not rotated, in which case the carrier is specifically attached to the traction cable 2 by the rotating element Traction cable 2 is towed.

A preferred mode of use of the linking device 15 can be described in the following manner: the carrier 3 is first positioned in the return station 8 and then pulled by the traction cable 2 to the drive station 9, uncoupled from the traction cable 2 to surround the drive pulley 12. It travels and is then reattached to the traction cable 2 to be driven to the intermediate station 10. The carrier 3 is then fixed in the intermediate station. Traction cable 2 in the entire usage mode The rotation is driven by the drive pulley 12 at the traveling speed Vc.

In the initial position, the fastener 16 is in the open position O, the transfer belt 38 is in position C, and the carrier 3 travels along the bypass circuit C1. The carrier 3 is then placed at the level of the output cam 25 of the return station 8. Advantageously, the carrier 3 can be fixed at the level of the output cam 25. In order to insert the traction cable 2 into the outer casing 21 of the fastener 16, or to pull the traction cable 2 from the outer casing, the carrier 3 is placed so that the main axis 22 coincides with the tensioned traction cable 2. The output cam 25 triggers the closing of the fastener 16, and the rotating elements 17 to 20 are in contact with the traction cable 2 and are driven to rotate by the traction cable 2, and the tangential velocity Vtg of the rotating elements 17 to 20 is equal to the traveling speed of the traction cable 2. Vc, ie Vtg=Vc. The conveyor belt 38 is then moved to bring it into position B. In position B, the tangential velocity Vtg of the rotating elements 17 to 20 decreases and the frictional force of the rotating elements 17 to 20 with the traction cable increases. The increased friction increases the tangential velocity Vtr of the wheels 27 to 30 of the carriage 26. In position B, the carrier 3 begins to be towed because the tangential velocity Vtr of the wheel is increased based on the equation Vtr = Vc - Vtg. The conveyor belt 38 is then moved to position A, wherein the tangential velocity Vtg of the rotating elements 17 to 20 is zero. In position A, the tangential speed Vtr of the wheels 27 to 30 of the carriage 26 is equal to the traveling speed Vc of the traction cable 2, that is, Vtr = Vc. In position A, the carrier 3 is towed by the traction cable 2 at a travel speed Vc and the carrier 3 leaves the return station 8. It can therefore be noted that the stations 8 to 10 of the device 1 no longer have to be equipped with long and complicated acceleration sections, since the carrier 3 can be coupled to the traction cable 2 from the stationary position of the carrier 3.

In order to decelerate the carrier 3, the transport belt 38 moves from position A to position B when the carrier 3 reaches the drive station 9. In the position B, the traveling speed Vc is kept constant, the tangential speed Vtg of the rotating elements 17 to 20 is increased, and the tangential speed Vtr of the wheels 27 to 30 of the bracket 26 is decreased based on the relation Vtr=Vc-Vtg. The carrier 3 is therefore (specifically) due to the bracket 26 The tangential speed Vr of the wheel decreases and decelerates. The conveyor belt 38 then moves from position B to position C. In position C, the tangential velocity Vtg of the rotary elements 17 to 20 is equal to the travel speed Vc of the traction cable 2, since the rotary elements 17 to 20 are attached to the traction cable 2 and are driven by the traction cable 2 by friction . Further, in the position C, the tangential speed Vtr of the wheels 27 to 30 of the carriage 26 is zero and the carrier 3 is not moved in the drive station 9. It can therefore be noted that the stations 8 to 10 of the device 1 no longer have to be equipped with long and complicated deceleration sections.

When the carrier 3 is stopped in the drive station 9, the fastener 16 is opened, the opening of the fastener 16 can be triggered by the input cam 24 of the station 9 or by the control unit 32, and the traction cable 2 is withdrawn from the outer casing 21 of the fastener 16. . It can be noted that the control unit 32 can also be coupled to the adhesive member 23 by the connecting member 47 to control the opening and closing of the fastener 16. The opening of the fastener 16 is obtained by lateral movement of the rotary members 17 to 20 on each side of the main axis 22 of the outer casing 21 to release the outer casing 21 to withdraw the cable 2 from the fastener 16. More specifically, in order to draw the cable 2 from the outer casing 21, the cable 2 is turned up or down in the terminal stations 8, 9 by the steering sheave, which is not presented here for the sake of simplicity. The opening of the fastener 16 is typically performed in the terminal stations 8, 9 to cause the carrier to travel around the pulleys 12, 13 of the stations 8, 9. The carrier 3 is then separated from the traction cable 2 and can travel along the bypass circuit C2 to travel around the drive pulley 12. The terminals 8, 9 typically include a motorized tire system to move the carriers along the curved loops C1, C2.

Advantageously, the carrier 3 can be fixed in the intermediate station 10 while the traction cable 2 remains driven at the travel speed Vc and the fastener 16 is in the closed position F. Therefore, it is no longer necessary to uncouple the carrier 3 from the traction cable 2 for the fixed carrier 3.

Advantageously, the joining device 15 can comprise a guiding member positioned along the main axis 22 when the rotating element is in the joint position F. The guiding member can be a rounded portion when it is with the traction cable Limit the friction when the wire 2 is in contact. Preferably, the guiding member includes a pair of guiding sheaves 48 to, in particular, retain portions of the traction cable 2 in the outer casing 21 as the fastener 16 passes over the tower on the wire. The guide sheave 48 is mounted to the sheave support members 49 to 52. In particular, the guide sheave 48 is mounted for rotational movement along an axis that is perpendicular to the major axis 22 of the outer casing 21 and perpendicular to the central axis of the retaining sheaves 17-20. Additionally, the sheave supports 49-52 are mounted for translational movement along an axis parallel to the translational axis T of the impeding sheaves 17-20. Preferably, the fastener 16 includes four sheave supports 49 to 52, a front top sheave support 49, a front bottom sheave support 50, a rear bottom sheave support 51 and a rear top sheave support 52. The front and rear lines are defined relative to the direction of the main axis 22 oriented in the direction of movement Y of the carrier. The top and bottom portions are defined relative to the central axis of the blocking sheaves 17-20. Each pair of guide sheaves 48 further includes sheaves mounted on the upper sheave supports 49, 52 and sheaves mounted on the bottom sheave supports 50, 51 such that each pair of guide sheaves 48 faces Position towards each other. The sheave supports 49 to 52 are translationally movable between the maintained position illustrated in Figure 2 and the released position illustrated in Figure 3. In the maintain position, the guide sheave 48 is positioned along the main axis 22 of the outer casing 21 to retain the traction cable 2 inside the fastener 16. The cable 2 can then be prevented from coming out of the fastener 16 when the carriers 3 to 5 are supported or compressed by the wire tower of the traction cable 2. In the release position, the guide sheave 48 is positioned to exit the main axis 22 to withdraw the traction cable 2 from the outer casing 21. The guide sheave 48 is particularly suitable for considering the change in the inclination of the traction cable 2 along the path of the carrier 3. In Fig. 4, a side view of one embodiment of a joining device 15 is presented. Figure 4 illustrates the action of the sheave supports 49 to 52. When the joining device 15 passes the tower supporting the traction cable 2, the cable 2 is bent in a downward direction in a concave shape. Cable 2 tends to take the position represented by the dashed line by reference number Z. In this case, the traction cable 2 is pressed against the guide sheave 48 of the bottom sheave support 50, 51. The bottom sheave support 50, 51 thus enables the traction cable 2 to be maintained In the outer casing 21. More specifically, the bottom sheave supports 50, 51 maintain the two ends of the portion of the cable aligned with the main axis 22 of the outer casing 21. In the opposite manner, when the linking device 15 passes through the tower of the compressed traction cable 2, the traction cable 2 is bent in a concave direction in the upward direction. In this case, the traction cable 2 is pressed against the guide sheaves 48 of the top sheave supports 49, 52. The top sheave supports 49, 52 thus enable the two ends of the portion of the cable to remain aligned with the main axis 22 of the outer casing 21. According to another advantage, the bracket 26 can include a displacement device 58 that cooperates with a set of tires of the bypass circuits C1, C2 to move the carriers 3 through 5 along the circuits C1, C2.

The adhesion of the detachable fastener 16 can be further enhanced, for example, by having the fastener 16 equipped with an additional detachable clamp 53. When the fastener 16 is in the closed position F, the detachable clamp 53 is controlled to open or close. The additional clamp 53 enables the carrier to be towed with the traction cable 2 having a large tilt.

The attachment device 15 can also include an actuator 54, as illustrated in Figure 4, to rotate the drive rotation elements 17-20 when the fastener 16 is in the open position O. In this manner, when the fastener 16 is closed, the sheaves 17 to 20 are prevented from rotating, which limits the frictional force when the sheaves 17 to 20 are prevented from coming into contact with the moving traction cable 2. The starter 54 can include a rod 55 having a first end coupled to the toothed wheel 44 and a second end coupled to the starter wheel 56. The terminal stations 8, 9 of the device 1 may in this case comprise a motorized drive system 57 for driving the starter wheel 56 and thus the rotating elements 17 to 20 to rotate. Preferably, the motorized drive system 57 drives the rotary elements 17 to 20 to rotate when the fastener 16 is in the open position O prior to closing. The motorized drive system 57 enables the rotating elements 17 to 20 to be driven to rotate at a tangential speed Vtg corresponding to the tangential speed of the traction cable 2, thus preventing wear.

Advantageously, a portion of the mechanical power provided by the traction cable can be recovered as The energy used to operate the systems of vehicles 3 to 5, such as, for example, a lighting system, an air conditioner, or any type of electronic device such as control unit 32, to provide an autonomous vehicle. In particular, the mechanical power can be recovered when the carriers 3 to 5 are on-line, in which case a portion of the power provided by the input shaft 34 or the output shaft 35 that is driven to rotate is recovered. When the carriers 3 to 5 are stopped by the rotating elements in the joint position F, the mechanical power can also be recovered, in which case a portion of the power supplied by the input shaft 34 that is driven to rotate is recovered. It is contemplated that when the carriers 3 to 5 travel along the curved loops C1 to C2, the power is mechanically recovered by the power provided by the rotating output shaft 35.

When the emergency stop request of the vehicle is made, all of the carriers 3 to 5 can be stopped by stopping only pulling the cable 2. This provides a significant advantage in terms of personal safety as compared to a tram-type device in which one vehicle may collide with another vehicle.

In Figures 10 and 11, a particular embodiment of a fastener 16 is presented. In this particular embodiment, the fastener 16 comprises at least four rotating elements 17 to 20 configured in such a way that when the four rotating elements 17 to 20 are in the joint position F, the traction cable 2 is in the outer casing 21 straight line. In other words, the traction cable 2 extends longitudinally along the main axis 22 of the outer casing 21. Such a fastener 16 enables the reduction to be provided to each of the four rotating elements 17 to 20 as compared to the configuration in which the fastener 16 illustrated in Figures 6 and 7 comprises two rotating elements 17, 18. The force of the traction cable 2 is tightened. The safety of the carrier latch to the traction cable 2 is thus enhanced. As illustrated in Figures 10 and 11, the fastener 16 includes two pairs of rotating elements 17 through 20, each pair including two rotating elements positioned facing each other. The fastener 16 can include a plurality of pairs of rotating elements that are continuously disposed adjacent one another along the major axis 22. In particular, the rotating elements 17 to 20 are positioned on each side of the fastener 16, i.e., on each side of the main axis 22. Preferably, the fastener 16 comprises two pairs of four blocking sheaves 17 to 20, the two sheaves 17, 20 are positioned on one side of the main axis 22 and the two other sheaves 18, 19 are positioned on the other side. In particular, when the sheave is prevented from being in the joint position F, the axis connecting the same pair of the center of the retaining sheave is perpendicular to the traction cable 2. The fasteners 16 can be configured to join the carriers 3 to 5 to the traction cable 2 in a removable manner (as illustrated in Figures 10 and 11) or in a fixed manner. In FIG. 10, the rotating elements 17 to 20 contact the traction cable 2 in the joint position F and on the opposite sides of the traction cable 2. In the joint position F, the rotating elements 17 to 20 cooperate with each other to fasten the traction cable 2 to connect the carrier to the traction cable 2. In fact, when the four rotating elements 17 to 20 are in the joint position F, the four rotating elements 17 to 20 apply a fastening pressure to the traction cable 2.

The invention has been described as being particularly suitable for any type of cable transport equipment, in particular, equipment having overhead or traction cables on the ground. The present invention maximizes the throughput of the device by minimizing the size of the station, in particular, without having to increase the size of the station by having the station equipped with a complex and large volume of start and deceleration sections.
