Abstract

PURPOSE: To provide a cable type carrying device capable of reconnecting carriers having an equal interval by separately controlling motion of the carriers. CONSTITUTION: As a carrier 3 reaches a station, it is removed from a cable 11 to be guided along a rail 2. In a speed reducing zone, a wheel 4 is engaged with a drive plate 36 of the removed carrier 3, and such wheels are driven in order at a reduced circumferential speed, so speed of the carrier 3 is reduced. A detection device 7 detects a pass interval between the two carriers 3 in order, and a control device 100 compares a predetermined interval with a pass timing of each carrier 3 to selectively actuate a clutch 57 for maintaining the predetermined interval. Speed of the carrier 3 is thus separately adjusted while it passes along a control zone of the wheel 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable conveying device, and more particularly, to a cable conveying device, and more particularly, to a cable conveying device, which generally transfers between at least one station at a higher location and at least one station at a lower location. The invention also relates to cable cars, seats, lifts, gondola lifts and other cable-type transport devices, in which devices for transporting passengers are suspended at spaced positions.

BACKGROUND OF THE INVENTION Cable transport devices for transporting personnel between a station at a relatively high altitude and a station at a relatively low altitude, e.g. between a station on a hill or mountain side and a lower station, e.g. on a valley side, are commonly used, e.g. It is widely used on slopes and in areas where it is advantageous or desirable to transport personnel, for example to mountain peaks.

In general, such cable transport devices include a transport cable that flexes endlessly around pulleys or wheels at high and low stations, and a plurality of passenger transport vehicles suspended from the cable at intervals. including.

There are various types of such "vehicles" or passenger carriers. For example, it may be a cabin, a gondola, or a vehicle that can carry multiple people. Also,
Personal seats or stools capable of carrying one or two passengers may be of the type or may consist of a simple T-bar member that carries the mounted individual up and down the ski slope. For purposes of discussion herein, the vehicle and the mechanism by which the vehicle is retained on the cable will be referred to as a suspension system for simplicity, as the device for supporting the person being transported.

Therefore, in addition - for boat fishing, the cable transport system has a mountain station and a valley station, each stage controller having wheels or pulleys around which the transport cable passes, and one of these wheels a plurality of carriers, such as cabins or stools, at least one of which is configured to be driven and further has a respective suspension device capable of coupling the carrier to the cable and disengaging the carrier from the cable; Equipped with

At least one of the stations disengages the suspension device from the transportation cable, moves the vehicle detached from the transportation cable in a direction of movement corresponding to the direction of travel of the transportation cable, and further disengages the suspension device from the transportation cable. The vehicle is equipped with a mechanism for reconnecting the carrier. After the vehicle is disconnected from the cable and before the transport is reconnected to the cable, the vehicle's movement mechanism is such that the passenger can exit the vehicle and the passenger can enter the vehicle. It is contemplated to reduce the speed of the vehicle after disengagement and accelerate the vehicle to the speed of the cable for reconnection.

At the station of the cable carrier equipped with carriers such as gondolas or stools, where the carriers are detached from the cable and recoupled to the cable, the detached carriers are recoupled to the cable with equal spacing. It is necessary to do so.

Generally, this interval is set at the valley station. For this purpose, a movement in which the carriers are guided on rails arranged outside the bogies or wheels, over which the cables pass, so that the carriers can move along one at a time, evenly spaced apart. A mechanism is provided.

The carrier suspended from the transport cable is therefore removed from the cable at this station and guided away from the cable on the guide rail. Typically, this guide rail is provided with a transfer chain that engages the carrier in the area where the detachment of the carrier from the cable is carried out and in the area where the carrier is reconnected to the cable. .

After the vehicle is reconnected from the cable, the vehicle
It is moved by a plurality of rollers driven with a circumferential velocity that decreases in the direction of movement of the carrier, thereby
The speed of the implement is reduced from the speed of the cable to allow passengers to safely enter and exit the vehicle.

Immediately upstream of the reconnection zone, the speed of the vehicle is increased to the speed of the cable and the speed of the vehicle is matched to the cable speed in order for the vehicle to be effectively reconnected to the cable. The rollers are driven with increasing circumferential speed.

The movement of the carriers in the disengaged state is achieved, as already mentioned, by a chain equipped with protruding yoke members at 4 to 5 m intervals that engage the carriers and move them at predetermined distances. Implemented by.

To the extent that the incoming vehicle has a different distance from the preceding vehicle, i.e. less than this predetermined distance at which the vehicle is reconnected to the cable, the distance of the vehicle before reconnection is determined by each vehicle. This is corrected because the tool is brought into the reconnection area only when it is engaged with one of the protruding flange members of the transfer chain.

However, if the spacing of the incoming vehicles is greater than a predetermined regular distance, this spacing cannot be modified in this way by the moving chain.

Since unequal spacing must be avoided in all cases, it has been proposed to delay the cable in the latter case. However, the complexity involved in delaying cables, the expense of equipment for accomplishing this purpose, and the attendant irregularities in cable transport equipment all create disadvantages.

Furthermore, in systems using moving chains,
A problem is often encountered in which the yoke member swings out of its engagement path with the carrier in its operative state and the yaw member does not always engage reliably. Because of this problem, the described system does not allow excessive spacing between the carriers to be reduced, since it is desirable to operate the cable and transfer chain at a substantially constant speed. It is clear that this is not properly possible.

The main object of the invention is to provide an improved cable transport device of a type which avoids the above-mentioned disadvantages, and which is able to guarantee even spacing of the conveyors, in particular in the case of under- and over-spacing of the incoming conveyances. The object of the present invention is to provide a type of cable conveyance device.

More broadly, it is an object of the invention to provide a cable transport system which can be operated with great reliability and uniformity, in particular with uniform spacing of the carriers.

It is another object of the invention that the independent control of the movement of the vehicle maintains uniform spacing in the area between the disengagement of the vehicle from the transport cable and the reconnection of the vehicle to the transport cable. An object of the present invention is to provide a cable-type transport device that allows the reconnection of a transport device.

The above and other objects will be apparent from the following description of the device according to the invention, namely that a conveyor movement mechanism acting on a conveyor detached from a cable can be a drive device which is responsive to the movement of the implement and which is provided on the vehicle transport device to change the speed of the device so that the speed of the vehicle on which this mechanism acts is increased or decreased relative to a normal or predetermined speed; Provides a combined measurement device. Driving this mechanism in the deceleration or acceleration region in the path of the carrier n W
is therefore controlled in response to this measuring device or sensor.

According to one aspect of the invention, the transport mechanism is provided with a control region between the deceleration region and the acceleration region with a drive connectable with the carrier and controllable in response to a sensor. Preferably, the sensor is arranged at the end of the deceleration region of the mechanism.

This sensor determines the time interval over which successive vehicles pass, a measurement of their spacing, and controls the mechanism so that the vehicles are moved to the reconnection area at a desired predetermined interval. Control the drive.

According to another fLi 11 of the invention, the deceleration and acceleration region of the transport mechanism for the vehicle detached from the cable engages with the vehicle as it is guided in the rail so that the vehicle is on the rail. formed by rollers or wheels that control the speed of the carrier as it moves along. Deceleration area and acceleration i! Control between areas? In the +J area, wheels are also arranged, the drive of which is controllable, and for this purpose an optional interlocking drive consisting of the wheels of the control area and a transmission is arranged, which drives this device. Its speed is controlled in response to output signals from the sensor via the sensor. A coupling device is provided for the coupled rotation of all wheels in the control zone, and the transmission device is provided with a device for driving these wheels and taking drive power from the transmission for the wheels in the deceleration or acceleration zone, and vice versa. can be provided.

Therefore, the system? Il? The wheels in Zone II are driven for the required length of time with either a reduced or increased circumferential velocity to effect either deceleration or acceleration of the engaged vehicle. However, in the control area, the wheels that can be connected to the carrier are provided in groups;
The wheels of each group are accelerated or decelerated for this purpose relative to the normal speed of movement of each vehicle.

Each group of wheels can be provided with a coupling device for rotating them together and the drive of a particular group can be taken from the transmission or drive chain of the wheels in the deceleration region or the wheels in the acceleration region. Can be done. This transmission has output shafts driven at different speeds and one of these shafts.
includes a clutch for selectively actuating one or the other shaft.

The above and other objects, aspects and advantages of the present invention will become readily apparent from the following description with reference to both figures.

Figure 1 shows one station of the cable transport system, where passengers board and disembark from the carriers of the transport system.

As can be seen from this figure, the cable conveyance device includes a cable disk or pulley 1, over which a transport cable 11 passes, supported by a conventional support tower, which is extended from this station to a station on the mountain side. or, if the station shown is on the mountain side, it extends from this station to the station on the valley side, both of which are identical except that they must each be equipped with a motor driving the cable disk 1 on one side. It can be seen that it is a structure.

Furthermore, this station comprises a guide rail 2 along which the carrier 3 is guided when removed from the cable 11 by means of a sliding mechanism, which will be described in detail below. As can be seen in FIG. 1, the carrier 3 may be a gondola 3a or a seat 3b, both of which are typical carriers carried by cable and used to transport personnel between stations.

The transport mechanism that propels the carrier 3 when it is disengaged from the cable 11 includes wheels 4, which are primarily used to slow down the carrier from cable speed to a speed at which a passenger can adjoin the carrier, and wheels 4, as will be described below. , the wheels 5 whose main purpose is to control the speed of the carriers and their spacing, and further accelerate these carriers to tension, and the wheels 5 whose main purpose is to control the speed of the carriers and their spacing, and to accelerate the carriers by connecting the η smell that is carried up to the speed of the cable. wheels 6 whose primary purpose is to accelerate the speed up to cable speed when each vehicle is reconnected to the cable.

The cable disk 1 is driven, for example, by a motor disposed within a motor housing 1a, although its details are not shown.

The components at this station are supported by a support or frame structure generally indicated at 12. The wheels 4.5 and 6 are furthermore journalled on a wheel support 13 which is fixed to the frame structure 12 via a bracket 13a shown in FIG.

The carrier 3 is connected to the cable 1 at a predetermined distance.
1 and when the carrier 3 is transferred to the station along with the cable 11, the carrier 3 is detached from the cable and moved along the rail 2 by means of wheels 4.5.6. Ru. Generally, this movement is either rapidly decelerated after the vehicle 3 is disengaged from the cable 11 to allow passengers to disembark, or accelerated again to the speed of the cable when the vehicle is reconnected to the cable. The vehicle is controlled to allow passengers to enter the vehicle before the transport.

FIG. 2 shows a suspension system for disconnecting the carrier from the cable 11 and reconnecting the carrier 3 to the cable 11.

As can be seen from this figure, the rail 2 is attached to the frame structure 1
This is a channel member supported by an L-shaped beam 2a held on a second bracket 2b.

Each carrier 3 comprises a transfer support 33 having rollers 35 guided in channels forming the rails 2 . In addition, this support 33 includes a clamp 34 having a pair of jaws which is engaged with the cable 11 and which is opened and closed by a lever actuated mechanism, only a portion of which is visible in FIG. Lever-actuated mechanisms for attaching and detaching clamps to and from cables in cable carriers are well known in the art and need not be described in detail.

The support 33 has a spring-biased lever 31 for operating the clamp 34 and has a roller 32 at the free end of this lever.
is provided. Lever 3 carrying roller 32
When the free end of 1 is pushed down, the clamp is released from the cable. Once the roller 32 is released to be moved upwards and the cable 11 is positioned within the clamp,
The jaws of the clamp are closed so that the carrier can grip the cable and follow the movement of the cable.

Since the rollers 32 are adapted to engage with a plate member 32a formed as a slope on the frame 12, the wheels 35
After the plate member 32a engages with the rail 2, the plate member 32a engages with the roller 3.
2 is displaced downwards to release the clamp 34 and allow the cable to pass downwards into the cable disc 1, causing the support 33 to roll on the rail 2. The support 33 further has a drive plate 36, which can be seen in FIGS. 2.3 and 4, which is driven by wheels 4.5 and 6 so that the support 33,
The speed of the carrier 3 is therefore controlled. The plate member 32a has 16
forming part of the guide rail structure indicated by and 16a
It is supported by the frame structure 12 at.

Therefore, in order to detach each carrier 3 from the cable 11,
Its roller 32 engages the guide rail 16 from above and deflects the lever 31 against its spring bias, opening the jaws of the clamp 34 and opening the clamp. Similarly, when the vehicle 3 is increased in speed, the rail 16 moves towards the roller 32.
, the lever 31 is swung upward by its spring bias and the clamp 34 automatically releases the cable l.
closed on l.

As can be seen in FIG. 3, the rail 2 is arranged outside the cable disc 1, around which the cable 11 is guided. The carrier 3 is guided in a rail 2, which is associated with three groups of wheels 4.5 and 6 which successively engage a drive plate 36 of each carrier 3. By engaging in this way, the carrier 3 is moved along the rail at a speed equal to the respective circumferential speed of the rollers 4.5 and 6, thereby controlling the speed of the carrier.

A motor 14 is arranged to drive the wheels 4.5 and 6. The motor 14 is connected to a reduction gear 43 by a load splitting gear 14a and a universal joint shaft 42.

The transmission 43 has a shaft 43 that directly drives one of the wheel groups 4.
It has a. The remaining wheels 4 are connected to the driven wheels 4 by means of a belt drive 41 which makes it possible to appropriately define the peripheral speed of the rollers 4 in order to bring about the desired reduction in the speed of the carrier 3. The first wheel of the wheel group 4 is driven by a take-off shaft 45 in a manner not shown in detail. axis 45
The drive via can compensate for slippage in the drive of the wheels 4. The wheels 4 are controlled in such a way that the circumferential speed of the wheels 4 is gradually reduced in the direction of movement of the carrier 3.

The carrier 3 then moves to the 5
A subsequent group of wheels 5 is encountered, all interconnected by V-belts and V-belt pulleys, indicated at 1.

Furthermore, the drive of the wheels 5 is carried out by the motor 14 via a shaft 52 and a further transmission g W, generally indicated at 53 and capable of generating a plurality of output speeds.

For example, the shaft 52 can include a direct drive shaft 54 connected to each wheel 5 via one T-magnetic latch 57. In addition, the drive shafts 55a and 56a are connected to the drive pulleys 55b and 56b, respectively, which are mounted on separate drive shafts 55 and 56, each of which is driven at a correspondingly different speed relative to the shaft 54. A drive V-belt boot J54a and 54b can be provided. The shafts 55 and 56 are connected to each wheel 5 by a further electromagnetic clutch 57. By selectively energizing the electromagnetic clutch 57, one of the three drivable wheels 5 is rotated at a corresponding speed;
The other two drive wheel axles will be disengaged from the electromagnetic clutch.

Axle 54 thus provides average speed to wheel 5, while axles 55 and 56 can provide reduced and increased speed, respectively.

The final wheel group 6 includes wheels 5 in the direction A in which the carrier 3 is moved.
It is located downstream of the The wheels 6 are also interlocked by a belt drive 61 and further connected to a universal shaft 62
and a further transmission 63 connected to one of the wheels 6. As in the case of the shaft 45, another shaft 65 connects the transmission 63 to one wheel of the wheel group 6 near the end of the wheel group 6 and in the area where the carrier is reconnected to the cable. In this way, the transmission 63
drives one of the wheels 6 directly, and this movement is transmitted on the remaining wheels via a V-belt drive, so that the wheels finally have a magnitude whose speed is equal to the speed of the cable. It has an increasing velocity in the direction of movement A until it is applied to the carrier.

The shaft 65 is a heald drive device as described above! Compensate for slippage at f 61.

A measuring device 7 for detecting the passage of the carrier 3 is arranged in the last section of the wheel 4 forming the deceleration zone. The detection device 7 is connected to the electromagnetic clutch 57 via the control device 100 and selectively operates this clutch.

The operation of the cable conveyor shown in FIG. 3 is as follows. When the carrier 3 reaches this station, it is detached from the cable 11 and guided along the rail 2 in the manner described above.

In the deceleration zone, the wheels 4 engage the drive plates 36 of the disengaged carrier 3. Since these wheels are driven one after the other at a reduced circumferential speed, the speed of the carrier 3 is reduced accordingly. This reduction in speed reduces the speed to the point where passengers can board and exit the vehicle.

The detection device 7 records two successive passage intervals of the carrier 3. If these vehicles get too close to each other, the following vehicles must be further slowed down in their movement. If the vehicles are spaced too far apart, the following vehicle must be accelerated; if the vehicle spacing corresponds to the desired spacing, this vehicle must both accelerate and decelerate. do not have. In this manner, the control device 100 compares the predetermined interval with the 1jli15 timing of each carrier and selectively operates the clutch 57 in response.

If the vehicle does not require acceleration or deceleration to maintain the predetermined spacing, the clutch on shaft 54 is energized and the clutches on shafts 55 and 56 are disengaged. If the vehicle is required to accelerate to close an excessive gap, the clutch on shaft 56 is energized and the clutch 57 on shafts 54 and 55 is disengaged. Conversely, if the vehicle needs to be delayed further to increase this distance, the clutch on axis 55 is energized and the clutch 57 on axes 54 and 56 is disengaged.

Thus, while the vehicles are passing along the control area of the wheels 5, their speed is adjusted individually and the adjustment is different from one drive axle to another while passing along the control area. This can be easily implemented by switching to , and errors in the spacing between two successive carriers 3 can be corrected.

At the end of the control zone, the vehicle is driven by wheels 6 in the acceleration zone.
engaged with and accelerated uniformly to the speed of cable 11;
The carrier is now connected to the cable 11 in the manner described above.

FIG. 4 is a modification of the system of FIG. 3, in which the control area has its wheels separated into two wheel groups 5a and 5b. In this system, two universal shafts 52a driven by transmission 14 provide regular speed to each wheel group via shaft 54' and an uninvolved magnetic clutch 57. The wheel group 5a further includes:
It includes a shaft 55' coupled to shaft 54' by a V-belt pulley system. Wheel group 56 increased V
As in the embodiment of FIG.
A control device is provided to actuate the electromagnetic clutch 57.

In response to detecting the passing distance of the vehicle 3, the sensor 7 in this embodiment detects the axis 54' at normal speed or at a reduced speed by comparing with the normal speed.
It is clear that wheel 5 of wheel group 5a is driven by wheel 5'. Similarly, the wheels of wheel group 5b are driven at a normal speed or a speed greater than the normal speed. Therefore, the control i
The provision of a switchboard that switches one wheel group to a different speed or vice versa when another wheel group engages the vehicle during the vehicle's passage through one area. It's unnecessary. This system allows the speed of one vehicle to be increased or decreased as desired relative to other vehicles in a controlled area.

Of course, the embodiment of FIG. 4 also illustrates the principle of dividing the wheels of the control area into groups of wheels driven at the normal speed or at speeds higher or lower than the normal speed, thereby By controlling the speeds individually, carrier spacing modifications can be carried out more effectively. Of course, following similar principles, some wheels in an acceleration or deceleration region can be controlled individually with respect to other rolls in that region to control the spacing between carriers.
