Description

  The present invention relates to a vehicle brake provided in a rope pulling type vehicle used in a transportation facility that pulls a vehicle with a rope and carries it.

  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. Such a 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 cable is extended along these rails. The rope is wound around a pulley or winch provided at the summit stop, and the vehicle is connected to at least one end of the rope. Then, by driving the pulley pulley and the winch, the rope is wound up or drawn out, and the vehicle is moved between the two stops to operate.

  The vehicle is not equipped with a drive device or the like for self-running. Therefore, if the rope is cut, the vehicle will run away to the foot of the mountain. Therefore, the vehicle is provided with a vehicle brake that acts on the rail, and the vehicle is stopped by this when the rope is cut or the vehicle runs away (see, for example, Patent Document 1).

The vehicle brake 23 includes a brake body 24 pivotally attached to the carriage 13, brakes 26 a and 26 b and a slide piece 27 slidably supported inside the brake body 24, and the brake body 24 in the vertical direction. And an actuator 25 for rotating the actuator.

  The brake body 24 includes a thick plate-like holder portion 31 and a lever portion 32 that is fixed to both sides of the holder portion 31 and extends in the front-rear direction. One end of the lever portion 32 is attached to the wheel of the carriage 13. The lower part 40 is pivotally supported by a pin 30, and the brake body 24 is rotatable up and down around the pin 30. The lower surface of the holder portion 31 is recessed upward to form a recess, and the surface of the recess that faces the rail 11 is a slope surface 33 that is symmetrically inclined in the left-right direction. In the concave portion of the holder portion 31, a pair of brake elements 26 a and 26 b are arranged to face the rail 11. The brake elements 26a and 26b have a symmetrical shape in plan view, and are formed so that the surface facing the rail 11 is parallel to the rail 11, and the opposite side matches the inclination of the inclined surface 33 of the recess. It is formed to be inclined. The upper portion of the holder portion 31 is provided with a plunger 38 that penetrates from the upper surface to the concave portion (see FIG. 5). In normal times, the tip of the plunger 38 abuts against the brake elements 26a, 26b, and the brake elements 26a, 26b The rail 11 is fixed at a position that is separated from both sides.

  As shown in FIG. 6, the right and left side upper ends of the brake elements 26 a and 26 b are formed with a protruding portion 34 that protrudes upward, and the holder portion 31 is fitted with the protruding portion 34. A groove 35 is formed. The brake elements 26 a and 26 b include a brake shoe 36 on the surface facing the rail 11. A support plate 28 is provided on the lower surface of the holder portion 31 to support the brake elements 26a and 26b. The surface in contact with the brake elements 26a and 26b inside the holder portion 31 is subjected to low friction processing by attaching a low friction sheet or the like, and the brake elements 26a and 26b are slidable in the front-rear direction. .

  7 is a DD arrow view in FIG. As shown in FIGS. 5 and 7, a sliding piece 27 is disposed in the recess of the holder portion 31 adjacent to the brake elements 26 a and 26 b. The sliding piece 27 has a square bar shape, and both left and right ends are supported by guide grooves 37 formed in the holder portion 31. The inner surface of the guide groove 37 is subjected to low friction processing by attaching a low friction sheet or the like, and the sliding piece 27 is slidable in the front-rear direction. An L-shaped cover 29 is attached to the end portion of the holder portion 31 so as to close the upper end surface, so that the sliding piece 27 and the brake elements 26a and 26b do not come out of the end portion of the holder portion 31. It has become.

  A cylinder 39 of the actuator 25 is pivotally attached to the upper portion of the holder portion 31 so as to be rotatable in the front-rear direction. Similarly, the other end portion of the actuator 25 is pivotally attached to the carriage 13 so as to be rotatable in the front-rear direction. doing. The actuator 25 shown in this embodiment is an electric cylinder, and when energized, the cylinder 39 expands and contracts to rotate the brake body 24, and when energization is interrupted, the expansion and contraction is stopped and the position is maintained. As the actuator 25, a fluid cylinder, a pneumatic cylinder, or the like can be employed.

  With the above configuration, the vehicle brake 23 of the present invention operates as follows. First, during normal driving, the rope 12 is in tension even when the rope-traction type vehicle 10 is headed on either the high side or the low side. In normal times, the actuator 25 of the vehicle brake 23 is contracted, and the brake body 24 is rotated and held above the rail 11. The rope towed vehicle 10 includes a speed detector that detects the traveling direction and the traveling speed of the rope towed vehicle 10, and this signal is input to the control device 22. For example, the speed detector can be configured to detect the rotation direction of the wheel 15a or 15b by a rotary encoder or a tachometer.

  Next, when the rope 12 loses tension due to cutting or the like and relaxes, the mechanism or detector provided in the locking drum 16 detects this and transmits this signal to the control device 22. The control device 22 energizes the actuator 25 when the signal from the rope 12 is received and the signal from the speed detector becomes a signal in the direction in which the rope-traction vehicle 10 descends. The cylinder 39 is extended, and the brake body 24 is rotated in the direction of the rail 11. When the brake body 24 rotates to the position of the rail 11, the sliding piece 27 provided in the holder portion 31 comes into contact with and is pressed against the rail 11.

  Reference is now made to FIG. 8 for ease of understanding. FIG. 8 is a plan sectional view of the holder portion 31. In the figure, an arrow E indicates the moving direction of the rope pulling type vehicle 10. The sliding piece 27 pressed against the rail 11 is braked so as to slide in the arrow F direction as the rope-towed vehicle 10 moves in the arrow E direction by the frictional force with the rail 11. The child 26a, 26b is pressed. The brake members 26 a and 26 b fixed by the plunger 38 are released from the plunger 38 by being pressed by the sliding piece 27 and slide in the direction of arrow F together with the sliding piece 27. The brake elements 26a and 26b slide in the direction of the arrow F so that the distance between the brake elements 26a and 26b is narrowed by the inclination of the inclined surface 33, and the rail 11 is sandwiched from both sides. The frictional force between the brake elements 26a and 26b and the rail 11 By doing so, the rope pulling type vehicle 10 is stopped.

  As described above, according to the vehicle brake 23 of the present invention, when the sliding piece 27 is brought into contact with the rail 11, the sliding piece 27 slides to press and brake the brake elements 26a and 26b. Therefore, a complicated mechanism for sliding the brake elements 26a and 26b is not required, and the structure can be made inexpensively with a simple structure. Also, since the operation is simple, there are few failures and maintenance is easy. Further, during normal traveling, the holder portion 31 that performs braking is located at a position retracted above the rail 11, so that there is little possibility of malfunction.
