  A traveling carriage according to an embodiment of the present invention and a self-propelled elevator using the traveling carriage will be described in detail below with reference to FIGS. First, a traveling vehicle according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a view of a traveling carriage according to an embodiment of the present invention as seen from a side surface on an elevator entrance / exit side. FIG. 2 is a diagram for explaining the dimensions and the acting force of each component of the traveling carriage shown in FIG. FIG. 3 is a view of the traveling carriage according to the present embodiment as viewed from the front on the elevator entrance / exit side, and is a view showing a DD cross section from the arrow A side in FIG. 1. FIG. 4 is a view of the traveling carriage according to the present embodiment as viewed from the front on the elevator entrance / exit side, and is a view showing an EE cross section from the arrow B side in FIG. 1.

  1-4, 1 is a drive wheel, 2 is a driven wheel, 3 is a motor, 4 is a carriage frame, 4A is a carriage frame, 4B is a carriage side frame, 4C is a carriage screw portion, 5 is a lever support shaft, 6 is a lever, 7 is a wedge roller, 8 is a wedge, 8A is a wedge top surface, 9 is a push spring, 10 is a spring seat, 11 is a push bolt, 12 is a lock nut, 13A and 13B are bearings, 14 is a lever mechanism, 15 Is a stator, 15A is a stator torque reaction force support portion, 16 is a rotor, 17 is a drive shaft, 18 is a brake wheel, 19 is a driven shaft, 20 is a traveling carriage, 21 is a car or counterweight, 22 is a suspension portion, 23 Is a brake device, 30 is a guide rail, 30A is a rail facing plane A, and 30B is a rail facing plane B.

  First, an outline of a traveling carriage in a self-propelled elevator according to an embodiment of the present invention will be described. In the traveling carriage 20, as a method of generating a large vertical drag N acting on the wheels so that the guide rail 30 and the wheels 1 and 2 do not slip, the pressing force T generated by the push bolt 11 is applied to the wedge 8 and the lever. 6 is used to convert the normal force N of the wheel into a booster. Further, the booster can be saved in space by being disposed in the space between the car or counterweight 21 and the guide rail 30.

  Further, the traveling carriage 20 is provided with a driving wheel 1 and a driven wheel 2, and a motor 3 is disposed on the driving wheel 1 side so as to be driven by a pair of driving wheels 1 by frictional force with the guide rail 30. Further, by providing the braking device 23 on the driven wheel 2 side, the motor 3 and the control device can be installed in a small space, and a large driving force and braking force can be obtained.

  Furthermore, the material of the driving wheel 1 and the driven wheel 2 can be changed by providing the braking device 23 only on the driven wheel 2 side without providing the braking device 23 on the driving wheel 1 side. The driving wheel 1 is important because the friction coefficient during driving, especially during acceleration, is important. On the other hand, the driven wheel 2 is driven because the braking force when the elevator stops, that is, the static friction coefficient, is important. Appropriate materials having necessary friction characteristics can be selected for the wheel 1 and the driven wheel 2, respectively, and stable driving force and braking force can be exhibited.

  Next, the structure of the traveling cart 20 according to the present embodiment will be described with reference to FIGS. The bogie frame 4 is one structure in which two bogie vertical frames 4A facing the left and right guide rails shown in FIG. 3 (viewed from the side of the elevator entrance / exit) are connected by a bogie horizontal frame 4B (FIG. 3). The bold dotted line is the carriage frame 4). A carriage screw portion 4C is provided on the carriage stand frame 4A, and a push bolt 11 is attached thereto.

  A lever support shaft 5 is attached to the cart standing frame 4 </ b> A, and a lever 6 is attached to the lever support shaft 5 so as to be rotatable around the lever support shaft 5. A wedge roller 7 that is rotatably attached is attached to one end of the lever 6. Further, a bearing 13A is attached to the other end. The lever mechanism 14 including the lever support shaft 5, the lever 6, the wedge roller 7, and the bearing 13 </ b> A is attached to the left and right carriage stand frames 4 </ b> A one by one, and a total of four are attached to the traveling carriage.

  Of the lever mechanism 14, the drive shaft 17 is rotatably supported by two bearings 13A respectively attached to two lever mechanisms attached to the rail facing plane A side (see FIG. 3). Drive wheels 1 are attached to both ends of the drive shaft 17. Further, the driven shaft 19 is rotatably supported by two bearings 13A respectively attached to two lever mechanisms attached to the rail facing plane B side. The driven wheels 2 are attached to both ends of the driven shaft 19 (see FIG. 4). The driving wheel 1 and the driven wheel 2 are in contact with each other so as to sandwich the rail facing planes 30A and 30B of the guide rail 30, respectively.

  A wedge 8 is in contact with the wedge roller 7, and when a pressing force T is applied to the wedge upper surface 8A via a pressing spring 9 and a spring seat 10 by a pressing bolt 11, a lever wheel 14 drives a driven wheel 1 and a driven wheel, respectively. A normal force acts on 2. The pressing bolt 11 fixes the pressing force T by the lock nut 12. The push spring 9 may be a coil spring. For example, if a disc spring is used, the height dimension can be saved.

  The relationship between the vertical drag N and the pressing force T by the pressing bolt 11 is expressed by the equation (1) based on the wedge effect and the lever principle.

N = (L1 × T) ÷ (2 × L2 × tan α) (1)
Here, L1 and L2 are the lever dimensions shown in FIG. 2, and α is the wedge angle shown in FIG. Equation (1) is obtained from the relationship N ′ = T × cos α / (2 × sin α)
N = N ′ × L1 / L2 = (L1 × T) / (2 × L2 × tan α)

  As said Formula (1) shows, it is a booster which can increase pressing force T by a push bolt. As can be seen from the equation (1), the booster is formed using tan α and the ratio of L1 and L2 as parameters.

  A motor 3 is attached to the drive shaft 17. The motor 3 is rotatably supported on the drive shaft 17 by a bearing 13B attached to the stator 15. The rotor 16 is fixed to the drive shaft 17. The stator 15 is fixed to the carriage frame 4 by a stator torque reaction force support portion 15A. The stator torque reaction force support portion 15A is made of a relatively flexible material such as rubber, and has a structure in which only the motor torque reaction force generated in the stator is received and supported by the carriage frame 4.

  With the above structure, torque generated by the motor 3 is transmitted to the drive wheel 1 via the rotor 16 and the drive shaft 17. Here, if the vertical drag N increased by the lever mechanism 14 and the friction coefficient of the driving wheel 1 and the guide rail 30 are μ, the driving wheel 1 generates a frictional force F = μN and travels by the driving force generated by the motor. The carriage 20 can be raised and lowered along the guide rail 30.

Next, a modified example of the traveling carriage 20 according to the present embodiment will be described with reference to FIG. FIG. 11 is a view showing a modification of the traveling carriage that does not use the wedge shown in FIG. In this modified example, the wedge 8 is not used, and a load is generated on one side of the lever 6 by the pulling force T ′ of the pulling bolt 36, and the mechanism is used for boosting by the lever principle. This method may be used when the vertical drag N is not necessary to boost the wedge effect. The relationship between the vertical drag N and the pulling force T ′ by the pulling bolt 36 is based on the principle of leverage.
N = (L1 × T ′) ÷ (L2) (2)
It is shown by the above formula (2).

  Next, the mounting position of the braking device 23 will be described. For example, FIG. 8 shows a part where the braking force is applied. A brake device is attached to the pulley 33 or a rail brake device which is attached to the car 31 or the counterweight 32 and directly grips the guide rail. The corresponding configuration is also included in the embodiment of the present invention. Here, the case where the brake device 23 is attached to the traveling carriage 20 will be described.

  FIG. 4 shows the EE cross section of the traveling carriage 20 from the side of the arrow B in FIG. 1, and the braking wheel 18 is fixed to the driven shaft 19. When a braking force is applied to the braking wheel 18 by the brake device 23, a braking force is generated in the traveling carriage 20 by the frictional force F (see FIG. 2) between the driven wheel 2 and the guide rail 30.

  Here, by providing the brake wheel 18 on the driven shaft 19 side, the motor 3 (see FIG. 3) attached to the drive shaft 17 side can secure a sufficient space in the rail facing direction and obtain a predetermined motor torque. Therefore, there is an advantage that the degree of freedom in design is increased. In particular, when two braking wheels 18 are provided to obtain a predetermined braking force as shown in FIG. 4, the arrangement of the motor 3 and the brake device 23 can be efficiently arranged in a space-saving manner.

  As shown in FIGS. 3 and 4, when the motor 3 is attached to the drive shaft 17 and the brake wheel 18 is separately attached to the driven shaft 19, the materials of the drive wheel 1 and the driven wheel 2 can be changed. . The driving wheel 1 is important because the friction coefficient during driving, especially during acceleration, is important. On the other hand, the driven wheel 2 is driven because the braking force when the elevator stops, that is, the static friction coefficient, is important. An appropriate material having necessary friction characteristics can be selected for each of the wheel 1 and the driven wheel 2, and there is an advantage that a stable driving force and braking force can be exhibited. As the material of the drive wheel 1, for example, high carbon steel, aluminum alloy, resin, rubber material or the like can be considered.

  On the other hand, as the material of the driven wheel 2, for example, cast iron or aluminum alloy is conceivable. Needless to say, other materials may be selected as appropriate. Further, since the distance between the drive shaft 17 and the driven shaft 19 can be increased by increasing the wheel diameter of the driven wheel 2, the motor outer diameter can be increased, which is effective when it is desired to increase the motor torque. It is.

  Next, the modification about the attachment position of the braking device 23 regarding this embodiment is demonstrated using FIG. FIG. 5 shows a modified example of the mounting position of the braking device in the traveling carriage according to the present embodiment, and is a cross-sectional view seen from the arrow A in FIG. When the brake wheel 18 is attached to the drive shaft 17 and is disposed between the carriage stand frame 4A and the motor 3, the brake wheel 18 can have a large diameter, which has the advantage of increasing the degree of freedom in designing the braking force. The braking wheel 18 is attached to the driven shaft 19 side, and the positional relationship between the motor 3 and the braking wheel 18 is arranged in the same positional relationship with respect to the rail facing direction (the axial direction of the driven shaft, see FIG. 3). However, the same effect can be obtained (even if the diameter of the brake wheel 18 is large, the outer diameter of the motor 3 can be increased). It will not be disturbed).

  Next, the attachment position of the traveling carriage 20 according to the present embodiment will be described with reference to FIGS. The self-propelled elevator system to be attached may have a structure in which the counterweight 31 and the counterweight 32 are suspended by a rope 34 as shown in FIG. 8, or only the elevator car 31 is raised and lowered as shown in FIG. A system configuration may be used.

  FIG. 8 shows an example of the mounting position of the traveling carriage 20 that is installed under the counterweight 32. However, both the upper part of the car, the lower part of the car, and the upper and lower parts of the car (required by providing the traveling car 20 above and below). Securing the driving force), the counterweight can be mounted on the counterweight, below the counterweight, or both above and below the counterweight. FIG. 10 shows an example where the traveling carriage 20 is attached under the car 31. However, any of the attachment positions on the car, below the car, and above and below the car may be used.

  A method of fixing the car 31 or the counterweight 32 and the traveling carriage 20 in FIGS. 8 to 10 will be described with reference to FIGS. 1 and 3. The passenger car or counterweight 21 is placed on the carriage stand frame 4A of the traveling carriage 20, and the weight of the passenger car or counterweight 21 is supported by the traveling carriage 20.

  Next, another modification of the method for fixing the car or counterweight 21 and the traveling carriage 20 will be described with reference to FIGS. 6 and 7. In another modified example, the suspension portion 22 of the car or the counterweight 21 is in contact with the wedge upper surface 8A, and the weight of the car or the counterweight 21 is supported by the wedge 8. In this other modification, the force due to the weight of the car or counterweight 21 is added in addition to the pressing force T by the push bolt 11, and the vertical drag N generated on the driving wheel 1 and the driven wheel 2 can be increased. In addition, the support structure by the suspension part of the cage or the counterweight on the upper surface of the wedge is not limited to the case where the traveling carriage is installed under the cage or the counterweight, but when it is installed on or above and below the cage or the counterweight. However, it is naturally possible depending on the structure of the suspension.

  As described above, the characteristics of the traveling carriage according to the embodiment of the present invention will be described. The traveling carriage has a driving device having a driving wheel and a driven wheel, a braking device having a braking wheel and a brake, a wedge and a lever. The booster is provided, the driving force and the braking force can be stably secured, and the space saving can be achieved by the arrangement structure of the wheels.

  Furthermore, the self-propelled elevator according to the present embodiment reduces the size of the motor by improving the life of the rope and reducing the diameter of the drive wheel, compared to the elevator of the slip type driven by the frictional force generated between the rope and the sheave. Can be planned. To explain this, in the slidable method using a sheave, the diameter of the sheave (rotary body driven by the motor) is defined by the diameter of the rope according to the car load, and the sheave diameter must be increased. Therefore, it is required to increase the torque of the motor corresponding to the sheave diameter, and the motor must be enlarged. On the other hand, in this embodiment, the rope is not related to the driving force, the driving wheel can be made as small as possible, and the torque of the motor corresponding to the diameter of the driving wheel is only required. The motor can be downsized. Furthermore, in the shingle method, the rope tends to have a short life due to wear with the sheave driven by the motor. However, in the self-propelled elevator of this embodiment, the rope suspends the weight from the carriage and the suspension weight. Since it is not involved in driving, it does not wear, and the life of the rope can be extended as compared with the slidable type.
