Description

The present invention relates to a vehicle for a cable-traction type inclined transport facility that transports passengers and goods by towing the vehicle on a slope with a cable.

Cable-traction type inclined transport equipment, which transports passenger cars or carts (hereinafter collectively referred to as vehicles) by pulling them on inclined ground, is known as passenger equipment such as cable cars that transport people, and industrial equipment such as inclines that transport goods. The general configuration of cable-traction type inclined transport equipment is such that a vehicle is movably placed on laid rails, and the cable connected to the vehicle is wound and driven by a winch or pulley, allowing the vehicle to move along the rails.

The general configuration of cable-pulling inclined transport equipment is to place a pulley for driving the cable at the station on the mountaintop side, wrap the cable around the pulley, and connect vehicles to both ends of the cable, or connect a vehicle to one end of the cable and a counterweight to the other end, so-called bucket-type operation (see, for example, Patent Document 1). In addition to the bucket type, there is also a system in which a vehicle is connected to the end of the cable, and the cable is wound up or let out by a winch installed at the station on the mountaintop side to operate the vehicle (see, for example, Patent Document 2).

The pulley and winch drum for driving the cable are connected to an electric motor via a reduction gear, and the motor's speed is controlled to rotate the pulley, towing the vehicle with the cable for operation. The input shaft of the reduction gear or the output shaft of the electric shaft is equipped with a drum or disk type braking device, which operates when the vehicle arrives at a station, and detects the operation of the braking device to cut off the power supply to the electric motor, and the cable or vehicle is held stationary by the braking force of the brake (see, for example, Patent Document 3).

For relatively large-sized inclined cable-towed transport facilities, a simple vehicle with a handrail around the perimeter has been proposed, in which many people can board the vehicle and evacuate to higher ground in the event of a tsunami (see, for example, Patent Document 4).

In such cable-towed inclined transport facilities, vehicles are towed by cables, so safety is required, such as preventing the vehicle from running away due to cable breakage or equipment failure, and ensuring that the vehicle stops and is held in a parked position. The present invention was made in consideration of these circumstances, and aims to provide a vehicle for cable-towed inclined transport facilities that can reliably stop the vehicle and hold it in a parked position.

In order to solve the above problems, the present invention provides a cable-pulling inclined transport facility that has a running rail laid parallel to both sides of a vehicle between stations with a difference in elevation, and a guide rail laid between the running rails, and a cable is wound around the vehicle that runs on the running rail while being guided by the guide rail, and both ends of the cable are hooked to a hoisting drum of a hoisting device installed at the station, and the cable pulls the vehicle and transports it by rotating the hoisting drum, characterized in that the vehicle is equipped with a vehicle brake that acts on the guide rail to apply the brakes.

According to the present invention, it is possible to reliably stop vehicles of cable-towed inclined transport equipment and maintain the vehicle's stopped position.

Specific embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing the entire cable-towed inclined transport facility. A track 13 is laid between a low-lying stop 10 and a high-lying stop 11, and vehicles 14 carrying cargo and passengers are provided on the track 13 in a movable manner. A cable 15 connected to a hoisting device 16 provided at the high-lying stop 11 is stretched along the track 13, and the cable 15 is wound around the bottom of the vehicle 14 as described below. When the hoisting device 16 is driven, the cable 15 is hoisted toward the high-lying stop 11, and the vehicle 14 carrying cargo and passengers is towed by the cable 15 and moves from the low-lying stop 10 to the high-lying stop 11.

Figure 2 is a plan view of the hoisting device 16. The hoisting device 16 shown in the figure is a so-called winch-type hoisting device 16 in which one end of the cable 15 is hooked to one hoisting drum 30a, the cable 15 is extended toward the vehicle 14, wound around a balancing pulley 26 and folded back, and then extended again toward the high-level station 11, and the other end is hooked to the other hoisting drum 30b, and the cable 15 is hoisted by rotating and driving both hoisting drums 30a and 30b.

The configuration for driving the winding drums 30a and 30b is the same, so the configuration for driving the winding drum 30a will be described below. The drum shaft 34 is inserted and fixed to the center of rotation of the winding drum 30a, and this drum shaft 34 is rotatably supported by a bearing 44 fixed on the drum frame 33. The side of the drum shaft 34 on the reducer 31 side protrudes from the bearing 44, and this protrusion is connected to the output shaft 35 of the reducer 31 via a coupling 36. The input shaft of the reducer 31 is connected to the electric motor 32 via a universal joint 38, and the winding drum 30 is rotated and driven by this electric motor 32. In addition, the input shaft of the reducer 31 is equipped with a disk-type brake 37, which brakes and holds the motor stopped.

Figure 3 is a side view of the vehicle 14, Figure 4 is a front view of the vehicle 14, and Figure 5 is a view taken along the line A-A in Figure 3. The vehicle 14 is composed of a lower frame 20 equipped with a total of 10 wheels 22, five on each side, an upper frame 21 for carrying cargo and passengers, and a support frame 23 for supporting the upper frame 21 on the lower frame 20. In a side view, the lower frame 20 is inclined so as to be parallel to the track 13, and the upper frame 21 is horizontal. The upper surface of the upper frame 21 is flat all over, and handrails 24 are provided around the outer periphery of the upper frame 21. At the low-altitude and high-altitude stations 10 and 11, boarding and alighting platforms are formed at the stopping positions of the vehicle 14 so as to be approximately flush with the upper surface of the upper frame 21, where cargo can be loaded and unloaded and passengers can board and alight.

The track 13 is composed of a guide rail 18 extending from the center of the vehicle 14, and running rails 17 extending from the left and right sides. The running rail 17 is a normal rail fixed to the top of an H-shaped steel, and wheels 22 roll on this normal rail. The guide rail 18 is also composed of a flat protrusion formed in the center of the top surface of the H-shaped steel, and a vehicle brake 27 of the vehicle 14 described below acts on this protrusion. The lower part of the lower frame 20 is provided with rotatable guide wheels 25 facing each other on the left and right at the front and rear, and the front and rear guide wheels 25 each clamp the web of the H-shaped steel of the guide rail 18 from both sides. This allows the vehicle 14 to move while being guided by the guide rail 18.

Furthermore, two balancing pulleys 26 are provided at the bottom of the lower frame 20 so as to rotate freely. The balancing pulleys 26 are arranged symmetrically in the left-right direction, and are located approximately in the center between the guide rail 18 and the running rail 17. A rope 15 extending toward the high platform station 11 is wound around each balancing pulley 26 and folded back, and the vehicle 14 is pulled by winding up the left and right ropes 15 at a uniform speed. At this time, even if the winding speeds of the left and right ropes 15 differ, the resulting difference in traction force is absorbed by the rotation of the balancing pulleys 26, which causes the ropes 15 to move to the left or right, and the left and right ropes 15 pull the vehicle 14 with the same traction force. Therefore, the traction force of the ropes 15 does not induce yawing of the vehicle 14.

Next, four vehicle brakes 27 are provided on the side of the lower frame 20 facing the high platform station 11. The vehicle brakes 27 are hydraulic release type vehicle brakes 27 that apply braking by clamping the upper protrusion of the guide rail 18 with pads using the operating force of a spring, and release the braking force by operating a hydraulic cylinder provided in the vehicle brakes 27. This hydraulic cylinder is operated by hydraulic pressure generated by a separately provided hydraulic unit or manual pump.

The vehicle brake 27 configured in this manner operates in the following cases. First, if the cable 15 breaks or the hoisting device 16 malfunctions and the cable becomes loose, this is detected mechanically or electrically and the vehicle brake 27 is operated to brake the vehicle 14 and fix the vehicle 14 in a stopped position to prevent the vehicle 14 from running away. Furthermore, when the vehicle 14 arrives at a stop 10 or 11, the drive of the hoisting drums 30a, 30b of the hoisting device 16 is stopped to operate the brake 37, and the vehicle brake 27 is also operated on the vehicle 14. In this way, the vehicle 14 can always be stopped in the same position even if the load on the vehicle 14 changes.
