Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for detecting an overload of a carrier in a boarding zone of a stop of an automatic circulation cableway equipment.

[0002]

2. Description of the Related Art Cableway equipment is one in which a carrier is gripped by a gripping machine around a rope wound between pulleys on both ends, and the carriage is operated as the rope moves and is transported. There is a lift using a chair-type carrier and a ropeway using a passenger car-type carrier, and it is generally known that it is often used for transporting skiers in snowy areas or for transporting passengers in mountain tourist areas. Recently, it is becoming more and more desirable to use the cableway equipment as a general transportation medium or medium-sized transportation.

[0003] Since the cableway equipment runs from the ground to a high place along the rope, it is demanded that the passenger capacity of the carrier be more strictly observed than in the case of other transportation means.
Correspondingly, in the conventional cableway equipment, when passengers get on at a boarding place or a boarding zone, an attendant attends and accurately checks the passenger capacity based on the safety monitoring and allows the passenger to board. It was

On the other hand, on the other hand, recently, labor saving and remote monitoring by a television monitoring device have been implemented in other general transportation facilities, new transportation systems, etc. It also tends to be required in the field.

[0005]

Needless to say, in carrying out such labor saving and remote monitoring, it is of course necessary to prevent the safety level from lowering than in the past, but in such a case. In the past, almost no consideration was given to equipment for ensuring safety. The present invention responds to such a situation by automating cableway equipment, and for example, when performing remote safety monitoring using a television monitoring device or the like, prevents overloading of a carrier to ensure passenger safety. The purpose or purpose of the invention is to provide means or auxiliary means for ensuring the above.

[0006]

In order to achieve this object, the present invention relates to a carrying device in which a carrying device is gripped by a gripping machine between the pulleys at both ends and a cable wound between the pulleys, and the carrying device moves with the movement of the rope. At the stop, the gripping machine is a safety device provided near the boarding zone at the stop of the automatic circulation type cableway that has been able to discharge the rope and be transferred along the rail. There, a movable rail provided in communication with the rail along a passage path of the carrier, a load detection unit that detects a load of the movable rail and outputs a load signal, and the carrier is one of the movable rails. A transporter detector that detects a passing position and outputs a transporter signal, and a control device that inputs the load signal and the transporter signal and outputs a determination signal, wherein the control device is the transporter. When the signal is input, the load signal is preset. Compared to a set value and outputs a determination signal is obtained by constituting the carriage load detecting safety device for an automatic circulating cableway when taken to take safety measures.

[0007]

The transporter load detection safety device for an automatic circulation type cableway according to the present invention is installed inside a cableway stop. A boarding area or a boarding zone is arranged along the rail within the stop, and when the carriage moves along with the movement of the rope, when it reaches the stop, it is separated from the rail and rolls along the rail to decelerate. In addition, the carrier that has reached the slow speed reaches the vicinity of the boarding zone in this state, and the passenger is treated as a passenger there.

A movable rail is provided in a passage path near the boarding zone so as to communicate with the rail. A load detecting means is arranged on the movable rail to detect the load of the carrier on the movable rail and send a load signal to the control device. Further, the movable rail is provided with a carrier detector, and when the carrier passes the movable rail position, a carrier signal is output to the control device. The control device receives the load signal and the carrier signal and outputs a determination signal. That is, in the control device, when the carrier signal is input, the load signal is compared with a predetermined set value, and if the value of the load signal is smaller than the set value, it is considered that the load of the carrier is within the allowable value. If the value of the carrier signal is larger than the set value, it is considered that the load of the carrier is overloaded, and the determination signal is output. Based on this discrimination signal, necessary safety measures such as a notification to the remote monitoring center, an alarm by voice, a colored light, or the stop of the departure of the carrier can be taken.
