Description

[Detailed Description of the Invention] The purpose of this invention is to quickly and safely rescue the passengers in the carrier when the cableway stops due to trouble with the mechanical or electrical system during passenger transportation and cannot continue operating. This invention relates to a passenger rescue device on a cableway.

Conventionally, if it became impossible to continue driving on a cableway without a crew member on board the carrier, a rescuer from the ground would climb up to a nearby support, attach a pulley to the towline, and use the pulley to move the carrier along the towline. After getting close to the aircraft, rescuers were then operated by a winch installed on the ground to lift rescuers from the ground to the transporter to rescue the passengers.
However, with this method, the pulley itself could not be fixed to the tow rope, so there was a problem that it was unstable and lacked safety for rescue workers to climb from the ground. In addition, since the accident site (where the carrier stops) is uncertain, the time required to secure the winch to pull up the rescuers varies depending on the location, so in some cases it may take a long time. Sometimes it was necessary. Therefore, passengers are left waiting for rescue for a long time.
In some cases, the passengers were left in the carrier, which caused great psychological distress to the passengers, which was a problem given the need to rescue them to the ground as quickly as possible.

This invention was made in view of the above-mentioned problems, and includes a guide rope dropping device installed on one side of the exterior of the carrier so that the guide rope can be dropped from the carrier as necessary, and A rescuer lifting device pulled up to a carrier via a rope is hooked onto and detached from the guide rope dropping device,
This not only ensures the safety of rescue workers and passengers when climbing or descending, but also speeds up rescue work, solving the problems of the conventional technology.

This invention will be described below with reference to embodiments. 1st
The figures and FIG. 2 show a carrier 1 on a cable. A guide rope dropping device 2 is installed on one side of the outside of the carrier 1.
Set up. This guide rope dropping device 2 is the third
As shown in the figures below, it is a box 4 that houses one guide rope 3, and the bottom of the box 4 can be opened and closed. The bottom plate 5 of the box body 4 is hinged to the box body 4 on one side with a hinge 6, and on the other side is hooked with a hook 7. When the hook 7 is operated via a string 8 guided into the carrier 1, As shown by the chain line in FIG. 4, the bottom plate 5 is designed to open due to its weight. Instead of operating the string 8, the hook 7 may be operated from the ground using a remote control device 9 such as a light emitting device or a radio wave transmitter, as shown in FIG.

Inside the box body 4, there are two pulleys 1 at the top.
0 and 10 are installed so as to be rotatable, and a stopper 11 is attached to the bottom of one of the pulleys 10.
A lock plate 12 is fixed substantially horizontally at the center of each of the two. The guide rope 3 is slidably attached to the pulleys 10, 10, and one end is guided downward through a hole (not shown) formed in the stopper 11 and a locking hole 13 formed in the lock plate 12, and the guide rope It is wrapped around 14. The other end of the guide rope 3 is guided downward through a hole 15 formed in the lock plate 12 and wound around another spool 16, which is screwed onto a bolt 17 protruding from the inner wall of the box body 4. (Figure 6).

According to the guide rope dropping device 2 described above, the string 8
Alternatively, when the bottom plate 5 is opened by the remote control device 9, the spool 14 first falls as shown in FIG. 5a, and the guide rope 3 hangs down to the ground. Next, when the spool 16 screwed onto the bolt 17 is rotated by pulling the guide rope 3 hanging down on the ground, the spool 16 and the bolt 17 are unscrewed.
The spool 16 falls as shown in FIGS. 5b and 5c, and the other end of the guide rope 3 also hangs down to the ground.

On the other hand, as shown in FIGS. 7 and 8, the rescuer elevating device 18 that is attached to and detached from the guide rope dropping device 2 has a rescue rope 20 attached to a pulley block 19, and a rescue rope 20 attached to one side of the rescue rope 20. seat belt 2
1, and a hook 23 is provided above the pulley block 19 via a carabiner 22.

The pulley block 19 has, for example, a wheel that can be rotated only in one direction (arrow 24) suspended horizontally within a frame, and a rescue rope 2 is connected to the wheel.
By winding the rescue rope 2 multiple times, the rescue rope 2
0 in the direction of arrow 24 is possible with half the force of the load (the weight of the person lifting/descending);
A device is used that can prevent movement in the direction opposite to 4 by applying a force that is a fraction of the load in the direction of arrow 24.

As shown in FIGS. 9 and 10, the hanging tool 23 includes a capped tube 25 having a diameter slightly smaller than the diameter of the hooking hole 13, and a sliding member fitted inside the capped tube 25. It is composed of a tube 26. The sliding tube 26 has a groove 27 formed in its upper part in the diametrical direction, and a locking pawl 2 is installed in the groove 27 via pins 28, 28 in a V-shape.
9 and 29 are biased in the expansion direction by springs 30 and 30, and the fitting length of the sliding tube 26 into the capped tube 25 is regulated. The end of the guide rope 3 is detachably connected to the upper part of the sliding tube 25.
The carabiner 22 is hooked into the connecting hole 31 at the lower part of the body, so that the rescuer elevating device 18 can be connected thereto.

Next, the connection and removal of the rescuer elevating device 18 and the guide rope dropping device 2 will be explained.

That is, one end of the guide rope 3 suspended above the ground (the side that was dropped first) is connected to the sliding tube 25 of the hanging device 23, and the rescuer lifting device 18 is also connected to the sliding tube 25. and guide rope 3
By pulling the other end to the ground side, the rescuer elevating device 1
8 toward the guide rope dropping device 2 (Fig. 7). The capped tube 25 that constitutes the hanging/unhooking tool 23 passes through the locking hole 13 of the lock plate 12,
Subsequently, the latching claws 29, 29 engage the springs 30, 30.
When passing through the latching hole 13 while closing against the elasticity of the latching claws 29, 29, the springs 30, 30
The rescuer elevating tool 18 expands due to its elasticity, and the hooking tool 23 and the lock plate 12 are engaged with each other via the hooking claws 29, 29 as shown in FIG.
is hooked to the guide rope dropping device 2 (Fig. 8).

In this state, the rescuer 32 cooperates with the assistant 33 to ascend to the carrier 1 via the rescuer elevating device 18.
It is possible to go inside the carrier 1 and rescue the passengers inside the carrier 1 to the ground using the rescuer elevating device 18. In addition, if there are many passengers in carrier 1,
It is also possible for the rescuer to bring another descending tool into the carrier 1 and perform rescue operations efficiently using the different descending tool. When the rescue is completed, the rescuer 32 also descends to the ground, and then retrieves the rescuer elevator 18 used for the rescue. This collection can be done as follows. That is, first, the end of the guide rope 3 that hangs down on the ground is pulled to further pull up the hooking tool 23. By pulling up the hanging/removing tool 23, the capped tube 25 is removed.
When the crested cylinder 25 comes into contact with the stopper 11 and the rising of the crested cylinder 25 is stopped, only the sliding cylinder 26 rises to be inserted into the crested cylinder 25, thereby expanding it into a V-shape. The latching claws 29, 29, which had been in place, are closed and housed in the capped tube 25, resulting in the state shown in FIG. 12. Then, when the guide rope 3 that is being pulled on the ground is loosened, the hook 23 passes through the hook hole 13 of the lock plate 12 and descends downward, so the rescuer elevating tool 18 and the hook 23 are recovered to the ground. be able to. Further, the guide rope 3 can also be recovered together with the hanging/removing tool 23. Therefore, when the work is completed, the box 4 of the guide rope dropping device 2 is placed in the carrier 1.
When the cable is restarted, there is no risk of the cable getting caught in surrounding trees, steel towers, etc. due to hanging of the rope.

As explained above, according to the present invention, a guide rope dropping device is installed on one side of the outside of the carrier, and the rescuer lifting equipment is moved to the guide rope dropping device by operating the guide rope dropped from the guide rope dropping device. It is made removable, and all the members hanging down from the carrier, such as rescuer elevating tools and guide ropes, can be recovered at the end of the rescue, which has the effect of safely and quickly rescuing passengers.

In particular, the guide rope dropping device can be constructed by winding the guide rope slidably housed inside the box around two spools, and screwing one of the spools onto a bolt protruding from the box. This can be done from one end to the other, preventing the guide rope from getting tangled, which is effective in speeding up the work.

In addition, if the rescuer elevating device is constructed by wrapping the rescue rope multiple times around a wheel that can rotate in only one direction, and providing a seat belt on one side of the rescue rope, the load can be lowered by several times. Since it can be countered with just one force, it reduces labor and improves safety as well as work efficiency.
