Description

The present invention relates to an operating device for a cable-traction type inclined transport facility that transports passengers and goods by towing vehicles on slopes with cables.

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).

In relatively large transport facilities among these cable-towed inclined transport facilities, a driver's cab is provided at the station, and the operation of the vehicle is controlled by an attendant from the cab. On the other hand, in relatively small transport facilities, a driver's cab as described above is not provided, and the vehicle is operated by the personnel on board who operate it from within the vehicle.

The present invention is primarily intended for use with the relatively small transport equipment described above, and aims to provide an operating device for a cable-towed inclined transport equipment that requires fewer operations when operated by personnel inside the vehicle, and therefore can be easily operated.

To solve the above problems, the present invention provides a cable-pulling inclined transport system in which rails are laid between stations with different elevations, a cable is connected to a vehicle running on the rails, the cable is wound around a sheave of a prime mover installed at the station, and the cable pulls the vehicle for transport by rotating the sheave. The vehicle is equipped with a door opening/closing button for closing the vehicle door and a human presence sensor for detecting passengers inside the vehicle, and the vehicle begins to move when the human presence sensor detects a passenger when the vehicle door is closed.

The present invention reduces the amount of operations required by passengers, making it easier for even physically disabled passengers or passengers who are uncomfortable operating machinery to operate the train.

Specific embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a longitudinal track section showing an example of a track for a cable-tracted inclined transport facility. As shown in the figure, the track is formed by connecting a mountain base station 10 at a low altitude to a mountain top station 11 at a high altitude. Rails 12 are laid connecting both stations 10 and 11, and a cable 13 is extended along the rails 12. One end of the cable 13 is connected to a vehicle 14, the middle part is wrapped around a driving device 15 provided at the mountain top station 11 and folded back, and the other end is connected to a counterweight 16 on the rail 12. In this way, the vehicle 14 and the counterweight 16 connected to the cable 13 in a bucket-like manner move in opposite directions along the rail 12 between the two stations 10 and 11 by driving the driving device 15.

Figures 2 and 3 are a side view and a front view of the summit station 11. In each figure, the upper cable 13a connected to the vehicle 14 is wound around the upper guide roller 17 provided at the summit station 11, deflected downward, and wound around the sheave 19 of the prime mover 15 installed at the bottom. The cable 13 wound around the sheave 19 is deflected upward again and wound around the lower guide roller 18, deflected toward the track. A counterweight 16 is connected to the end of the lower cable 13b that extends toward the track in this way.

The prime mover 15 includes the sheave 19, the reduction gear 20, and the electric motor 21. The sheave 19 rotates via the reduction gear 20 by driving the electric motor 21, and the cable 13 moves and the vehicle 14 moves along the track. A brake 22 is provided between the reduction gear 20 and the electric motor 21, and the rotation of the sheave 19 is braked via the reduction gear 20 by the operation of the brake 22. In addition, a rotation detector 23 is provided at the end of the electric motor 21. The rotation detector 23 is a rotary encoder or the like that transmits a signal according to the amount of rotational displacement of the electric motor 21, and the signal transmitted from the rotation detector 23 is input to an operation control device 24 that controls the rotation of the electric motor 21. Note that, although the embodiment is described here in which the amount of rotational displacement of the electric motor 21 is detected by the rotation detector 23, the amount of rotational displacement of the sheave 19 may be directly detected by the rotation detector 23.

The operation control device 24 receives signals from various detectors that detect the conditions required for operation, and controls the rotation speed of the electric motor 21 based on these signals to automatically accelerate or decelerate the vehicle 14, and also controls the operation of the brake 22 according to the conditions. As one of the detectors, a stop switch 25 that detects the vehicle 14 is provided at the vehicle 14 stopping position of the mountaintop stop 11. This stop switch 25 detects that the vehicle 14 that has entered the stop has reached the stopping position, and outputs this signal to the operation control device 24. In response to this signal, the operation control device 24 operates the brake 22 to stop the movement of the sheave 19 or the rope 13, and cuts off the power to the electric motor 21. As a result, the vehicle 14 stops at the specified stopping position, and is kept in the stopping position by the braking force of the brake 22.

At the platforms of each of the stops 10 and 11 and inside the carriages 14, there are provided control panels with buttons for starting operation and opening and closing the carriages 14 doors. Figure 4 is a front view of the platform control panels provided at the stops 10 and 11. The platform control panel 30 is equipped with an intercom 31, a platform operation button 32, an alarm 33, and a selector switch 34. The intercom 31 is a device for voice communication with the operation control room, and the platform operation button 32 starts the carriages 14 when operated. The alarm 33 issues a voice message about any abnormality that occurs in the equipment, and the selector switch 34 selects whether the operation is enabled or disabled, and is operated to disable the carriages 14 during equipment inspections, etc., to prevent danger during the inspection.

Figure 5 is a front view of the vehicle operation panel installed inside the vehicle 14. The vehicle operation panel 35 is equipped with an intercom 36, which functions in a manner similar to that of the platform operation panel 30 described above, a vehicle side operation button 37, and a selector switch 39, and also has a door opening/closing button 38 for opening and closing the doors. Also, a human presence sensor is installed inside the vehicle 14 to detect whether or not a passenger is on board.

With the above configuration, vehicle 14 is operated as follows. First, a passenger boarding vehicle 14 presses the platform side operation button 32 on the platform operation panel 30 installed on the platform to start operation. If vehicle 14 is stopped at a stop where passengers are present at this time, the doors of vehicle 14 open and passengers can board. Also, if vehicle 14 is stopped at a stop on the opposite side, after vehicle 14 moves to the stop where passengers are present and stops, the doors of vehicle 14 automatically open and passengers can board.

Next, after boarding the vehicle 14, the passenger operates the door opening/closing button 38 to close the door of the vehicle 14. At this time, if the human sensor in the vehicle 14 detects the passenger, the vehicle 14 automatically starts moving toward the other stop. On the other hand, if the passenger does not operate the door opening/closing button 38, the door automatically closes and the vehicle 14 remains stopped. Also, if the human sensor does not detect the passenger after the door is closed, the vehicle 14 does not move and remains stopped at the stop. Note that as the human sensor, a passive sensor that detects people by receiving infrared rays emitted from the human body, a laser scanner that detects people by emitting a laser, a 3D camera, etc. can be used. Next, when the vehicle 14 with the passenger on board arrives at the other stop, the vehicle 14 stops at a specified position as described above, the door automatically opens, and the passenger gets off.

As described above, according to the present invention, passengers can easily operate the train, even if they are physically disabled or have difficulty operating machinery, because there are fewer operations to be performed by passengers. In addition, passengers can prevent viral infections and other infections caused by contact because there are fewer areas that come into contact with when operating the train.
