Description

[Detailed explanation of the invention] (a) Purpose of the invention [Field of industrial application] This invention is a rescue device used in the field of cableways to rescue passengers on a carrier when the operation of a cableway stops unexpectedly. Regarding the hook device, especially when there are multiple carriers in the same span of the cable, it is possible to perform rescue quickly without having to change the device.

[Prior Art] When a cableway becomes inoperable due to a power outage, mechanical failure, or some other reason, passengers must be lowered and rescued as quickly as possible.
Various devices have been proposed for this purpose. However, because the rescue work involved danger or the equipment was complicated, few of them were fully satisfactory.

Although it is the simplest rescue device among the conventionally known rescue devices, it is easy to use and economical, so it is possible to have a large number of them, so rescue operations can be carried out simultaneously if necessary. The one shown in FIG. 5 is one that is widely used because it can quickly rescue a large number of passengers.

In FIG. 5, a cable 122 is supported and stretched by a cable receiver 142 installed on a support column 141, and the cable 122 has a cable gripping device 143a, a cable gripping device 143a,
Carriers 144a and 144b are suspended via 143b. Here, we will discuss the case where the cableway has come to an emergency stop and we are attempting to rescue passengers (not shown) currently on board the carriers 144a and 144b.
4a, 144b, the staff member climbs up the support 141 on the upper side of the slope of the cable 122 and lowers the cable 122.
Q Suspend the rescue hook device 101 near _one point.

As shown in FIGS. 4A and 4B, the rescue hook device 101 has a roller 110 pivotally mounted above a frame 102 bent into a hook shape via a pin 109, and the roller 110 is mounted on a cable 122. The frame 102 is for rolling the frame 102.
An end 103 extends from the cable 1
This is to prevent the roller 110 from falling off from the roller 22. Further, a retaining cable 131 and a rescue cable 132 are provided below the frame 102 via a ring 130.
A rescue lowering device 133 with a lowering device 133 is connected and suspended. Here, the rescue descending device 133 is used to evacuate from a high place in the event of a fire, etc., and has a speed regulating function to wrap around the rescue rope 132 in a hanging manner and prevent the descending speed from becoming excessive during evacuation. Equipment equivalent to known or commercially available equipment can be used.

In FIG. 5, the rescue hook device 101 suspended at the point _Q1 rolls down under its own weight due to the slope of the cable, so the staff member holds the holding cable 131 and moves it near the carrier 144a while suppressing acceleration. Achieve a certain Q of ₂ points. Here, one staff member holds the holding rope 131 while another staff member holds the end of the rescue rope 132, and in this state, the person is transferred to the rescue belt 132a at one end of the auxiliary rope 132. Thereafter, the rescue rope 132 is released and the passengers are lowered to the ground.

Next, after moving the rescue hook device 101 from point _Q2 to point _Q3 via the rope gripping machine 143a position,
Other carriers 144b within the same span of the cable 122
passengers must be rescued.

However, as shown in FIG.
3 and the rope gripping machine 143a interfere with each other in the shaded area A and cannot pass through.

Here, if the rescue hook device is configured such that the end portion 103 does not extend, it can pass through without interfering with the rope grasper 143a, but if such a configuration is adopted, the rescue hook device There is a risk that it may derail from the line 122 and fall off.

Here, conventionally, a staff member transfers to the rescue belt 132a and another staff member winds up the rescue rope 132 to ascend to the vicinity of the rope gripping machine 143a, where the rescue hook device 101 is moved from the _Q2 point. After removing it and suspending it again at ₃ points,
The next step was to carry out rescue work for the carrier 144b.

[Problems to be solved by the invention] Because of this kind of work, passengers in the carriage 144b, or in the carriages following it, have to wait for rescue for a long time in an uncertain situation, and the rescue personnel have to However, they had to work on unstable scaffolding, and some kind of improvement was desired.

The present invention was developed with the aim of improving this situation, and when attempting to rescue passengers in multiple carriers in the same span, it is possible to grasp the rope without interfering with the rope gripping machine by operating it from the ground. This was done in an attempt to provide a cableway rescue hook device that can pass through the ropeway position, thereby allowing rescue work to be carried out quickly and reducing the work burden on workers.

(b) Structure of the invention [Means for solving the problem] Corresponding to this purpose, the cableway rescue hook device of this invention consists of a cable and a gripping machine gripping the cable. It has a frame, a roller, and a stopper device that cooperate with each other to surround a gap large enough to allow the cable to pass through, and the frame has a hook shape and has an upper portion that supports the cable to be rolled along the cable. A roller is pivotally mounted, and a control cable and a rescue cable can be connected to the lower part, and the stopper device is slidably passed through a cylinder fixed to the frame, is biased by a spring, and is attached to the lower end. The rod of the stopper device has a rod to which an operating rope can be connected, and the rod of the stopper device is pressed by the elastic force of the spring to a position where the gap is almost closed, and the gap is opened to a width that allows the rope gripping machine to pass through. It is characterized in that it is elastically supported by the spring so as to be movable between the open position and the open position against the elastic force.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a cableway rescue hook device 1 according to the present invention will be explained below with reference to the drawings. As shown in FIGS. 1A and 1B, the frame 2 is formed by bending a metal plate strip material into a hook shape, and holes 4, 4 are bored near the top, and holes near the bottom end 5. 6 is perforated. A pin 9 is fixedly inserted through the holes 4, 4, and a drum-shaped roller 10 to be rolled on the cable 22 is pivotally attached to the pin 9.

Next, at a position near the lower end 5 of the frame 2,
A member 11 is fixed to the side by, for example, welding, and a tube 13 of a stopper device 12 is fixed to the member 11. The tube 13 is made of a hollow cylindrical material, and the locking portions 14 and 15 at both ends are provided with holes 14, respectively.
a, 15a, into which a rod 16 is slidably inserted. The rod 16 is shaped like a round metal rod, and stoppers 17, 17 are fixedly protruding from the middle of the rod 16 on both sides in the right angle direction. A coil spring 20 is interposed on the outer periphery of the rod 16 in the hollow of the cylinder 13 between the stoppers 17, 17 and the locking portion 15, and the elastic force of the coil spring 20 normally keeps the stopper 17
is in contact with the locking part 14, and at this time, there is a slight gap 21 between the upper end 18a of the rod 16 and the end 3 of the frame 2, so that they are close to each other. It is a positional relationship. On the other hand, a hole 19 is bored near the lower end 18b of the rod 16.

In this way, the ring 3 is inserted into the hole 6 of the frame 2.
A rescue lowering device 33 having a holding line 31 and a rescue line 32 is suspended through the hole 19 of the rod 16 via a ring 34.
There are suspension connections.

The protrusions 7 and holes 8 above the frame 2 are provided for the convenience of handling when carrying or suspending the rescue hook device 1 when the person in charge climbs the support 41 as will be described later.

[Function] Next, as shown in FIG. 2, the method of use and function of the rescue hook device 1 configured as described above will be explained.

The cable 22 is attached to the cable receiving device 42 installed on the support column 41.
are supported and stretched, and carriers 44a and 4 are attached to the cables 22 via cable gripping devices 43a and 43b, respectively.
4b is suspended.

The cableway has come to an unforeseen halt, and now the carriages 44a, 44
Let us now discuss the case of rescuing a passenger (not shown) on board the aircraft.

First, a person in charge climbs up the support 41 on the slope above the rope 22 from the position of the carriers 44a, 44b to be rescued, and suspends the rescue hook device 1 near point _P1 of the rope 22. That is, the rod 16 shown in FIG. 1 is pushed down, the gap 21 is expanded and opened, and the roller 10 is brought into contact with and supported on the cable 22, and then the rod 16 is returned to its original position by the restoring force of the coil spring 20. The opening is closed to prevent the rope 22 from falling off the roller 10.

As described above, the rescue rope 32 is connected to the rescue hook device 1 via the holding rope 31 and the rescue lowering device 33, and the operating rope 35 is connected to the rod 16, which hangs down on the ground. is holding cable 3
1 to prevent the rescue hook device from escaping down the slope.

Next, when the person in charge loosens the retaining rope 31, the roller 10 of the rescue hook device 1 rolls along the rope 22 due to its own weight, and when it reaches point _P2 , which is a position near the rope gripping device 43a, The rescue hook device 1 comes into contact with the rope gripping device 43a and is locked to prevent it from rolling downward and escaping. Here, the previous staff member operates the rescue rope 32 to lower the passenger on the carrier 44a to the ground while holding the passenger on the carrier 44a with the rescue belt 32a, thereby completing the rescue of the passenger on the carrier 44a.

Next, the rescue hook device 1 is moved in order to rescue the passengers on the carrier 44b located within the same span of the cable 22. At this time, as shown in FIG. When the operator pulls the operating rope 35 downward, the rod 16 compresses the coil spring 20 and is pulled downward, and the gap 21 opens wide, so the user can operate the retaining rope 31 in this state and release the rescue hook device. 1 can be moved from point _P2 to point _P3 without interfering with the rope gripping machine 43a. This situation is shown in FIG. When the pulling of the operating rope 35 is stopped, the rod 16 is raised and restored by the coil spring 20, and the gap 21 is slightly opened again.

In this way, by operating the holding rope 31 as described above, the rescue hook device 1 can be moved to the position of the carrier 44b, which is the next rescue point, and the next rescue operation can be performed.

(c) Effects of the invention As mentioned above, the conventional rescue hook device is difficult to operate under unstable footing conditions when the rescue operation of one carrier is completed and the rescue operation of the next carrier is completed. Relocation work had to be carried out, which was difficult and required a long time to rescue the passengers.

However, if the rescue hook device 1 of the present invention is used, since the upper end of the rod is closed, there is no risk of the rescue hook device falling off when moving on the rope, and once the rescue position is reached, the rescue hook device can be attached to the rope gripping machine. Because the rope is abutted, the first person in charge can operate the rescue rope from the ground and carry out a rescue even if another person does not have to secure the holding rope. By towing the rope, the rod can be easily operated and opened, allowing the rope gripping machine to pass through without interfering with the rope and moving on to the next rescue operation immediately. Therefore, passengers waiting for rescue can be quickly rescued, the work environment for staff is improved, and even one ground worker can perform rescue work by sequentially operating the tow rope and operating rope. This greatly contributes to ensuring the safety of cableways in emergencies.
