[0011]

[Function] In the fixed circulation type cableway, the ropes are tensioned and circulated in the pulleys pivotally installed at both ends of the ropeway, and a plurality of carriers are semi-permanently fixed and suspended on the ropes at equal intervals and moved to the ropes. Together with this, it is a cableway facility that operates a transporter for transportation. This type of cableway equipment is the most frequently used cableway in mountain ski areas.

At the stop, a rope having a plurality of carriers suspended around a pulley installed on the column. The rope is movably supported near the winding start position and the winding end position of the pulley to prevent the wrapped rope from coming off the pulley. Among these two sets of rope receiving devices, in particular, the rope receiving device provided on the winding start position side of the pulley is supported by the rope by interposing a load cell, so that the vertical direction acting on the rope receiving device can be improved. Have a structure that can detect the load. Normally, an empty vehicle carrier in which a passenger gets off passes through a receiving device with a load cell interposed. However, when the carrier that the passenger failed to get off at the exit position passes the rope receiving device, the load cell detects a larger load than usual. When the detected load signal of this large value is detected, the operation of the carrier is automatically stopped to ensure the safety of passengers when getting over the exit position.

However, the transit detecting device of the present invention is also used for a fixed circulation type cableway which is installed in a tourist spot and transports general tourists. Of course, it is possible.

[0021]

As described above, the overpass detecting device of the present invention is used when the carriage on which a passenger rides is wound around a pulley which is vertically erected at a stop and pivotally attached to a pulley for circular movement. In addition, near the winding start position of the pulley and the winding end position of the pulley, a rope receiving device for supporting and guiding the rope is provided so that the wound rope does not come off the pulley. There is. The rope is supported by the rope receiving device provided on the side of the winding start position, with a load cell interposed. Then, the load detection signal detected by this load cell is made a quantitative value in a predetermined time unit. Separately from this, the setting device of the signal processing unit between the load value detected when the passenger is not boarding and the load value detected when the carrier is passing the receiving device when the passenger is boarding. The value is set as a reference value, and the determination signal is output by comparing the magnitude with the reference value detected by the search device.

In this way, when the passenger arrives at the receiving device at which the passenger fails to get off the carrying device at the exit position set on the arrival side of the stop, the load detection signal from the load detecting unit of the load cell interposed in the receiving device. When the setting signal is output from the setting device, and it is output to the control device of the cableway through the external output unit to stop the operation of the carrier, the pulley is circulated and turned to the departure side. , It is designed to prevent passengers from leaving the cableway again and to ensure the safety of passengers. In this way, the passengers who have passed over may not touch the detection bar for detecting the overpass, which does not give a fear to the passengers. Furthermore, since the transit detection position is on the arrival side rather than the departure side, when the passenger overtakes the exit position, the operation of the carrier is stopped earlier than before, so there is an effect that the safety for the overridden passenger becomes higher. is there.
