Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cableway device.
A ski lift is a typical example of a cableway device. In a ski lift, a seat (carriage) on which a passenger can sit is suspended from a wire cable (hereinafter referred to as a "wire") which is looped around a return pulley and forms an endless track. The occupant can be transferred from the base at the foot of the mountain to the base at the top of the mountain by being driven by the power of the motor via the motor. In general, a ski lift is provided with a driving pulley for transmitting power to a base at the foot of the mountain, and a return pulley for simply folding a wire at a base at the top of the mountain.

[0002]

2. Description of the Related Art In a conventional ski lift, a bar arranged on a trajectory of a passenger or a bar is provided as a crossing detector of a cableway device for detecting that the passenger has not got off at a predetermined position. When pushing off the tied cord, a switch to stop the cableway device is used. By activating the crossing detector of the cableway device, it is possible to improve the safety of the cableway device, for example, to prevent the occupant in a state of getting off from being shaken down. In particular, when traveling around a return pulley, a strong centrifugal force acts on the transporter, which is dangerous, and it is required that the crossing detector be reliably operated.

[0003]

However, in the above-described over-travel detector using the conventional bar or string, the passenger is prevented from touching the bar or string instantaneously,
In the case of a child, there is a problem that a foot or the like does not reach the bar or the string from the beginning, and it is not possible to stop the cableway device even if a passenger gets over. On the other hand, with the recent increase in speed of ski lifts, the risk of ski lifts as described above tends to increase. It is possible to use a non-contact type sensor using infrared rays. However, there is a problem that the structure becomes complicated in order to maintain reliability in an environment exposed to cryogenic temperatures due to snowfall. There is.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a crossing detector for a cableway device which can reliably detect that a passenger has crossed with a relatively simple configuration.

[0005]

The present invention has the following arrangement to achieve the above object. That is, the present invention is provided in a cableway device including a closed-loop wire wound around a return pulley to form an endless track, and a carrier for a passenger suspended from the wire, and the passenger is provided with a predetermined In a crossing detector of a cableway device that detects that the vehicle has not descended at a position, the vehicle is rotatably supported near the turnaround pulley from a passenger's landing and supports the wire and rotates with the feeding of the wire. A single wheel, a single wheel shaft portion for rotatably bearing the single wheel, elastic receiving means for receiving the single wheel shaft portion with a predetermined elastic force so that the single wheel shaft portion can be lowered together with the single wheel, and the pulley turned back more than the single wheel. An operating wheel that is rotatably supported in the vicinity of the single wheel and contacts the wire when the single wheel is lowered by a predetermined distance together with the wire due to the load of the carrier on which the occupant rides, and rotates with the feeding of the wire. , By rotation of the operation ring comprises a sensor unit for generating a signal for stopping the cableway system.

Further, the sensor section is constituted by a cam provided integrally with the rotating shaft of the operating wheel and a switch section operated by the operation of the cam, so that the structure is not complicated. Its reliability can be improved.

Reference numeral 14 denotes a transporter, which is suspended from the wire 10 and has a seat for a passenger.
Reference numeral 20 denotes a jump detector of the cableway device (hereinafter, simply referred to as a “cross detector”), which detects that the occupant 50 has not got off at a predetermined position.

[0008] The crossing detector 20 has the following configuration. Reference numeral 22 denotes a single wheel, which is rotatably supported in the vicinity of the return pulley 12 rather than the landing 16 of the occupant 50, supports the wire 10, and rotates with the feeding of the wire 10. Numeral 24 denotes an elastic receiving means, which receives the single wheel shaft portion 25 with a predetermined elastic force so that the single wheel shaft portion 25 rotatably bearing the single wheel 22 can be lowered together with the single wheel. The elastic member of the elastic receiving means 24 is not limited to the coil spring as shown, but may be a plate spring, a member utilizing fluid pressure, or the like. Reference numeral 30 denotes an operating wheel, which is rotatably supported near the turnback pulley 12 rather than the single wheel 22.

Further, according to the crossing detector 20, the single wheel 22 can suitably buffer and absorb the vibration of the wire 10. Therefore, it is possible to preferably prevent the mere vibration of the wire 10 from propagating to the operating wheel 30 disposed closer to the return pulley 12 than the single wheel 22. Thereby, it is possible to preferably prevent the overtaking detector 20 from malfunctioning. Further, only when the operating wheel 30 rotates a predetermined angle, a signal for stopping the cableway device is generated from the sensor unit 32, and the descent of the wire 10 due to the simple hanging down (bending) of the wire 10 is detected. Is different. Therefore, malfunction of the sensor unit 32 due to vertical vibration caused by simple vibration can be suitably prevented, and reliability can be improved.
