DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passenger rescue device installed in an aerial cableway where no crew member is carried in a carrier such as a gondola lift or a ropeway.

[0002]

2. Description of the Related Art Conventionally, this type of cableway passenger rescue device has
Since the train is operated by being hung on a rope, it is common that a power source for the power is not always provided in the transporter.
As disclosed in Japanese Patent No. 6978, a connecting mechanism is disposed between a grip for gripping a cable and a carrier, and the grip and the carrier are connected during operation of a cableway, and a rope that links the grip and the carrier is lowered. A mechanism is arranged in the carrier, and a plurality of contacts for locking the lowering mechanism are protruded from the bottom of the carrier, for example, when an abnormality such as a cableway becomes inoperable,
When the passenger pulls the drawstring based on instructions from the driver's cab by radio or the like, the coupling mechanism is detached, the grip and the carrier are separated, and thereafter the rope is slowly pulled out due to the weight of the carrier and the carrier descends, After that, when even one of the contacts is displaced upward due to grounding or the like, there is a device in which the feeding of the rope is stopped and the transporter is lowered and stopped in a horizontal state.

[0003] Further, as disclosed in, for example, Japanese Utility Model Publication No. 55-147961, a rescue bag hung from a carrier,
A rope lifting / lowering mechanism connected to this is arranged in the carrier, and when an abnormality occurs, the passenger gets into the rescue bag, the rope is slowly fed out by the weight of both, and the rescue bag descends,
In some cases, the descent of the rescue bag stops when the rope has been paid out.

[0004]

However, in such a conventional cableway passenger rescue device, in the former case, the rescue operation is performed by separating the grip and the transporter by the operation of the passenger who does not have expertise in the rescue operation. In the latter case, rescue work is started by lowering the rescue bag by the operation of the passenger, so if it is configured to be able to reliably start the rescue work even by weak people such as elderly people and children, cableway operation The rescue operation is easily started due to the mischief of the passengers, and there is a risk that the carrying device and the rescue bag may start to descend, which is not only a cause of a new accident but also dangerous.

In the former case, the rescue operation cannot be stopped by stopping the lowering of the transporter unless the contact is displaced upward, and in the latter case, the rescue bag is lowered unless the rope is fully fed. Since the rescue operation cannot be stopped halfway, the carrier or rescue bag descends on an oblong obstacle that protrudes upward, such as a tree. In the case of a situation in which the transport device or the rescue bag hits without being completed, there is a possibility that the transporter and the rescue bag may be supported in a dot-like manner and rotate, which not only gives a passenger an uneasy feeling but also poses a serious danger.

Further, since the former and the latter have only a mechanism for slowly pulling out the rope and do not have the power to wind up the rope in a short time, after the transporter or the rescue bag descends and stops to rescue the passengers, If the rescuer does not take up the rope manually, the transporter and rescue bag will not rise, and it will take time to return the transporter and rescue bag to the initial state. There is a problem that road traffic or the like causes a traffic obstacle for a long time, and cannot be used as a passenger rescue device for an urban cableway.

In order to solve this problem, it is conceivable to arrange a power for raising the transporter and the rescue bag by winding up the rope in a short time, and disposing the battery in each transporter. Since the weight of the power battery is heavy, there is a problem that each transporter always carries a heavy dead weight, which is not economical.

The present invention has been made in view of the above circumstances, and has as its object to reduce the weight of a transporter while starting and stopping a rescue operation by operation of a rescuer and activating a return operation.

[0009]

Means for Solving the Problems In order to solve the above-mentioned problems, a technical measure taken by the present invention is to move a passenger out of an abnormally stopped cable to a carriage suspended on a cable of a cableway. A driving unit for the passenger escape moving means for controlling the operation of the driving unit by remotely operating the driving unit from the outside of the carriage, and connecting a power supply cord communicating with the driving unit from the inside of the carriage to the ground under the cable. Alternatively, it is arranged so as to be able to hang down toward a drive power supply provided on the water surface.

[0010] The drive unit of the passenger escape moving means is a detachable drive source of a coupling mechanism disposed between the grip for gripping the cable and the carrier, and a rope hoist for linking the grip and the carrier. Is preferred.

[0011] Further, the driving unit of the passenger escape moving means,
It may be a rope hoist connected to a rescue bag suspended from the carrier.

[0012] Further, the driving unit of the passenger escape moving means,
It may be a drive source of a traveling mechanism suspended from a carrier on a rope, or a gripping release driving source of a grip for gripping the rope.

[0013]

According to the technical means described above, according to the above technical means, when the cable is abnormally stopped, the passenger drops the power supply cord from the inside of the carrier and waits for the tip of the dropped power supply cord under the cable. When the rescuer connects to the driving power supply, the drive unit of the passenger escape moving means is remotely operated by the rescuer, and the passenger escapes and moves to the abnormally stopped cable.

[0014] With the remote operation of the drive unit of the passenger escape moving means, the coupling mechanism is disengaged, the grip and the carrier are separated, and the rope is pulled out from the hoist, whereby the carrier is suspended on the rope. After descending and rescuing the passengers from the lowered carrier, the carrier is raised and connected to the grip by performing the above operation in reverse.

[0015] Further, with the remote operation of the drive unit of the passenger escape moving means, the rope is pulled out from the hoist, so that the rescue bag carrying the passenger is hung on the rope and descends from the transporter. After rescuing the passengers from the bag,
By reversing the above operation, the rescue bag rises and is stored in the carrying device.

Further, with the remote operation of the drive unit of the passenger escape moving means, the traveling mechanism is suspended from the carrier on the cable, and then the gripping of the grip is released, whereby the carrier is suspended and the cable is suspended. Along the way, after rescuing the passengers from the moved carrier, the grip is used to grip the rope by performing the above-described operation in reverse.

[0017]

[0050]

As described above, the present invention has the following advantages.

When the cable is abnormally stopped, the passenger drops the power supply cord from inside the carrier, and the rescue worker waiting under the cable connects the tip of the dropped power supply cord to the driving power supply. The driver of the passenger escape moving means is remotely operated by the rescue worker, and the passenger escapes and moves to the abnormally stopped cable, so that the rescue worker can start and stop the rescue work and return work It is possible to reduce the weight of the transporter while increasing the power.

Therefore, as compared with the conventional rescue operation which is started by the operation of the passenger who does not have the expertise of the rescue operation, there is no possibility that the rescue operation is started during the operation of the cableway due to the mischief of the passenger or the like, and the operation is safe. At the same time, even if the transporter or the rescue bag falls on an oblong obstacle protruding upward, such as a tree, the situation can be coped with and the passenger can be rescued safely without giving the passengers anxiety.

In addition, compared with the conventional device which has only a mechanism for slowly pulling out the rope but does not have the power to wind up the rope in a short time, the operation of returning the transporter and the rescue bag is completed in a short time, and the cableway is cut off from the road. It is suitable as a passenger rescue device for urban cableway because it does not hinder road traffic for a long time when traveling on the top, etc., and the power to wind up the rope in a short time and the batteries are stored in each transporter. Since there is no need to dispose a battery in each of the transporters as compared with the configuration in which each of the transporters is disposed, each transporter does not need to carry a heavy dead weight by that amount, which is economical.
