JP5996292B2 - Braking device for rope pulling type transportation vehicle - Google Patents

Description

  The present invention relates to a braking device that is provided in a vehicle of a rope pulling type transportation facility that pulls a vehicle with a rope and transports the vehicle and stops the vehicle when the rope pulling the vehicle is broken.

  Equipment, such as cable cars and inclines, that pulls vehicles with ropes and transports people and goods can be operated even on relatively steep slopes. Many are used. This rope pulling type transportation facility is generally configured as follows. Two rails are laid in parallel between the foot of the foothill and the summit stop, and the rope is extended along these rails. The rope is wound around a pulley or winch provided at the summit stop, and a vehicle is connected to at least one end of the rope. Then, by driving a pulley or the like, the rope is wound up or drawn out, and the vehicle is moved between both stops to operate.

  In such a configuration, the vehicle of the rope pulling type transportation facility does not include a drive device or the like for self-propelling. Therefore, if the cable is cut, the vehicle will run away to the foot of the mountain. Therefore, in such a case, the cutting of the rope in the vehicle is mechanically detected, thereby operating a brake provided in the vehicle to stop the vehicle (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 9-295572

  As shown in Patent Document 1, the brake provided in the vehicle according to the prior art is configured to perform braking with a rail interposed therebetween. For this reason, there was a difference in the braking distance until the vehicle stopped when the rail surface was wet or dry due to rain, etc. It is desirable to stop at a fixed braking distance.

  The present invention has been made in view of such circumstances, and provides a braking device for a rope pulling transport vehicle capable of always performing stable braking without being affected by rain, snow, or the like. With the goal.

    Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal section of a track showing an example of a track of a rope pulling type transportation facility. As shown in the figure, the track is formed by connecting a foothill stop 10 at a low altitude and a mountain summit stop 11 at a high altitude, and a rail 12 is formed by connecting both stops 10 and 11. The ridges 13 are extended along the rails 12. One end of the rope 13 is connected to the vehicle 14, the intermediate part is wound around the prime mover 15 provided at the summit stop 11, and the other end is connected to the counterweight 16 on the rail 12. . Thus, the vehicle 14 and the counterweight 16 connected to the rope 13 in a slidable manner move in the opposite directions along the rail 12 between the two stops 10 and 11 by driving the prime mover 15. . Various controls of the prime mover 15 are performed by an operation control device 17 provided at the summit stop 11.

  FIG. 2 is a side view of the vehicle 14, and FIG. 3 is a front sectional view of the lower portion of the vehicle 14. The vehicle 14 travels by rolling a plurality of traveling wheels 14 a provided in the lower part on the two rows of rails 12. A rack rail 18 is laid between the two rows of rails 12 in parallel with the rails 12. The rack rail 18 may be a normal rack in which teeth are continuously formed, but is a pin rack in this embodiment. That is, as shown in FIG. 4, the rack rail 18 is obtained by fixing rack pins 18b having a circular or trapezoidal cross section at regular intervals between left and right U-shaped steel members 18a arranged in parallel.

On the other hand, a pinion shaft 22 is rotatably supported by a bearing 23 at a lower portion of the carriage frame 19 of the vehicle 14, and the pinion 20 and the brake disc 21 are fixed to the pinion shaft 22. The pinion 20 meshes with the rack pin 18 b of the rack rail 18, and the pinion 20 and the brake disk 21 rotate as the vehicle 14 travels. The brake disc 21 is stored inside the vehicle 14 and does not adhere to rain or snow .

  The carriage frame 19 includes a brake 24 that acts on the brake disc 21. The brake 24 performs braking and release by the interaction between the spring force and the hydraulic pressure, and the brake pad sandwiches the brake disc 21 by the spring force of the built-in spring during braking and brakes when released. By sending the pressure oil to the brake 24, the brake pad is released away from the brake disc 21. In order to perform such an operation of the brake 24, the vehicle 14 includes a hydraulic unit 27 configured by a circuit including a hydraulic pump, an oil tank, a solenoid valve, and the like.

  Next, the vehicle 14 is provided with a cable cut detection device that detects that the cable 13 has been cut. 5 to 7 show an example of the rope cutting detection device. FIG. 5 is a plan view showing a connecting portion between the vehicle 14 and the rope 13, FIG. 6 is a side view thereof, and FIG. It is the same front view.

  In each figure, the vehicle 14 is connected to five ropes 13. Each strip 13 is arranged in two upper and lower positions by sequentially changing the height position of adjacent strips 13 and is arranged in a so-called zigzag pattern so as not to overlap each other in plan view, The end portions of the respective strips 13 are inserted into the socket portions 31 of the thimble rods 30 and fastened with an alloy. The thimble rod 30 passes through an insertion hole provided in the carriage frame 19 and extends inward of the carriage frame 19, and a threaded portion 32 is formed at this end. A coil spring 33 and a spring receiver 34 are externally inserted into the extending portion of the thimble rod 30 from the screw portion 32 side, and a nut 35 screwed to the screw portion 32 is tightened to tighten the thimble rod 30 or the coil spring 33 to the carriage frame 19. It is locked on.

  A support plate 36 is formed on both sides of the lower portion of the carriage frame 19 with a position where the thimble rod 30 is hooked, and a shaft 37 is fixedly supported between the support plates 36. On this shaft 37, detection arms 38 and 39 are pivotally supported so as to be rotatable in the vertical direction. The detection arms 38 and 39 are long thin plates that are slightly longer from the position of the shaft 37 toward the extending direction of the rope 13 and slightly shorter toward the inner side of the opposite carriage frame 19. In the vicinity of the shaft 37, a substantially U-shaped leaf spring 42 is inserted between the shaft 37 and the carriage frame 19, so that the direction of the detection arm 38, 39 extending in the direction of the rope 13 rotates downward. The spring force is biased to move. Each detection arm 38, 39 has a substantially J-shaped hook 41 with a curved upper portion fixed to the leading end of the line 13 extending direction, and the hook 41 is hooked to the corresponding line 13 respectively. Thus, the detection arms 38 and 39 are supported. A limit switch 47 is fixed near the end of the detection arms 38 and 39 opposite to the hook 41 side. As will be described later, the detection arms 38 and 39 rotate when the rope 13 is cut, and the limit switch 47 is rotated. The switch 47 operates.

  With the above configuration, when the rope 13 that pulls the vehicle 14 is cut or relaxed, it operates as follows. FIG. 8 is a side view showing a state in which the rope 13 is cut. When the rope 13 is cut or relaxed, the rope 13 is lowered downward by its own weight, and the detection arm 38 or 39 that is hooked on the rope 13 is caused to move to the hook 41 by its own weight and the spring force of the leaf spring 42. The side pivots downward. The limit switch 47 detects the rotation of the detection arms 38 and 39 and transmits this signal to the control device 28 provided in the vehicle 14.

  The control device 28 that has received the signal from the limit switch 47 transmits an operation stop signal to the operation control device 17 at the summit stop 11 to stop the devices constituting the prime mover 15 and the hydraulic unit 27. Is transmitted to release the hydraulic pressure acting on the brake 24. As a result, braking is applied to the brake disc 21, rotation of the pinion 20 on the same axis as the brake disc 21 is stopped, and the vehicle 14 is stopped.

  As described above, the braking device of the present invention is configured such that the brake 24 operates and brakes the brake disc 21 stored in the vehicle 14, and the surface of the brake disc 21 is affected by rain and snow. Therefore, a stable braking force can be obtained. Further, since the rack rail 18 that meshes with the pinion 20 of the vehicle 14 is a pin rack in which the rack pins 18b are arranged at regular intervals, it is difficult for dirt and snow to accumulate, and troubles caused by these foreign matters can be reduced. In the above description, the case where the rope 13 is cut has been described. However, the present invention is not limited to this, and the brake 24 may be operated by the operation of various security devices or the push button operation in the vehicle 14. Good.
