2. Description of the Related Art Cableway equipment is operated by carrying a carriage suspended from a rope, and the cableway is roughly classified into a circulating cableway and an articulated cableway. Among these, the recirculating cableway is such that a rope or a tow line circulating between the pulleys at both ends is used to grasp a towing machine suspending a carriage, and the carriage is moved with the movement of the tow line. It moved and carried around the cableway track, and at the stop, the towing machine was unloaded from the towline, transported slowly along the rail, and treated as a passenger during this time. Things. On the other hand, the articulated cableway suspended the carrier using a rope or a toe that was stretched on both reciprocating lines between both ends and a rope or a tow that was movable between the two ends in the forward and reverse directions. A traveling machine is towed by a tow cord and rolled along the supporting rope, so that normally two carriages are alternately operated in forward and reverse directions.

It is widely known that these cableway facilities are frequently used for transporting skiers in snowy areas or for transporting passengers in mountain sightseeing spots. In recent years, there has been an increasing desire to use cableway facilities as general transportation means for medium- or small-volume transportation.

[0004] Since the cableway equipment operates at high altitudes from the ground along the rope, it is required that the number of passengers of the transporter adhere more strictly than in the case of other transportation means.
Correspondingly, in the conventional cableway equipment, when a passenger gets on a boarding area or a boarding zone, an attendant accompanies the passenger and checks the number of passengers accurately under the safety monitoring to carry out the boarding. Was.

[0005] On the other hand, recently, labor saving and remote monitoring by a television monitoring device have been carried out in other general transportation means and new transportation systems. It also tends to be required in the field.

[0006]

In carrying out such labor saving and remote monitoring, it is, of course, necessary to avoid lowering the level of safety than in the past. In the past, almost no equipment has been considered for ensuring safety. The present invention responds to such circumstances by automating cableway equipment and, for example, in the case where remote safety monitoring is performed using a television monitoring device or the like, preventing overloading of a transporter and ensuring passenger safety. The purpose or object of the present invention is to provide a means or an auxiliary means for ensuring the above.

[0007]

SUMMARY OF THE INVENTION In response to this object, a pulley at both ends is moved at a stop along a cableway for moving a rope along with movement of a rope wound between the pulleys to prevent overloading of the carriage. A safety device, which is provided in the vicinity of the boarding zone of the stop and which is a sign means for designating a timely time for detecting the load of the loader, and a sign provided on the carry means for detecting a display of the sign means and outputting a command signal. A detector, a load detecting means provided in the carrying device for detecting a load of the carrying body and outputting a load signal, and a command signal provided in the carrying device and inputting the load signal and outputting an overload signal; A discriminating device, comprising an overload warning means provided in the carrier and issuing an overload warning based on the overload signal, wherein the discriminating device receives the command signal and the load signal,
The load signal is compared with a predetermined set value to output the overload signal, and is configured as a load detection safety device for a cableway carrier.

[0008]

The load detecting safety device for a cableway carrier according to the present invention includes a sign means provided near a boarding zone at a stop of a cableway facility, a sign detector provided on the carrier, and a load detection device provided on the carrier. Means, a discriminating device provided on the carrier,
And an overload warning means provided in the transporter.

[0009] The sign means is fixed near the above-mentioned boarding zone, and displays an appropriate time to detect the load of the transporter.
On the other hand, when the sign detector provided in the transporter detects the display of the sign means, it outputs a command signal and sends it to the discriminating device. Further, the load detecting means provided on the suspension portion of the transporter outputs a load signal corresponding to the load or weight of the transporter body and sends it to the discriminating device. Similarly, in the discriminating device provided on the carrier, when the command signal and the load signal are input, an overload signal is output according to the conditions described later. That is, when the command signal is input, the discriminator compares the load signal with a predetermined set value, and if the value of the load signal is smaller than the set value, it is determined that the load of the transporter main body is within the allowable value. However, if the value of the load signal is larger than the set value, it is considered that the load of the transporter body is overloaded, and the overload signal is output. The overload warning means issues a warning by sound, color light, radio wave transmission, or the like based on the overload signal, and can take necessary safety measures.

If sl <N, the load on the transporter body 13 is considered to be within the allowable limit, and the safe operation is not performed. Absent. However, if the result of the comparison is sl> N, it is considered that the load or weight of the transporter body 13 exceeds the allowable value, and the overload signal so is output. Overload signal s
When o is output, the overload warning means 52 provided outside the transporter body 13 is activated based on this, and a warning is issued. As the overload alarm, a lighting alarm using a color lamp, an alarm by sound, an alarm by a radio signal as described later, or the like can be used.

The power supply device 53 provided in the transporter body 13
Is, for example, using a battery or the like,
0, for supplying power to the discriminating device 50, the overload warning means 52, and the like.

Each of the plurality of transporters 10, 10... Repeats the same operation each time they arrive near the boarding zone 21.

In this embodiment, the case of the automatic circulating cableway is described. However, the present invention can be similarly applied to the case of an articulated cableway.

(Other Embodiments) In the above embodiment,
Although the case of a device that issues a warning by a color lamp or sound as the overload warning means 52 has been described, as another application example of the present invention, a radio signal is transmitted by a wireless transmitter as an overload warning. FIG. 7 is a block diagram showing the configuration or the relationship of signal transmission.

In the figure, the left side of the figure from the overload warning means 52 is completely the same as that shown in FIG. In this embodiment, a radio transmitter 61 is used as the overload warning means 52. On the ground side, a controller 62 is provided. The controller 62 includes a radio receiver 63 and a switch 64.
