Abstract

PROBLEM TO BE SOLVED: To provide an emergency stop device which stops a moving body, etc., in an emergency as necessary regardless of the position of the moving body or a refugee. SOLUTION: Guide wheels 20 arranged in a base frame 80 are rolled on a guide rope 10 and the base frame 80 is made to be freely movable along the guide rope 10. A sliding guide 30 enlarged upward in width and provided with a slope 36 at the side of the guide rope 10 is arranged on the inner surface of a baseboard 81 which constitutes the base frame 80. A slider 40 is also arranged with the projected stopper pin 60 which penetrates the sliding guide. An emergency rope 55 is pulled to release the engagement of a trigger 50 with the stop pin 60 in the case of emergency. The slider 40 is moved upward by the pulling force of a sliding spring 70, guided to the side of the guide rope by the inclining groove 33 of the sliding guide 30 and brought into pressure contact with the guide rope 10 so that the moving body is stopped by friction resistance.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention relates to an emergency evacuation device,
The present invention relates to an emergency stop device provided on a guiding cable used in a gondola for overhead line maintenance work, rock climbing training, diver dive training, and the like.

[0002]

2. Description of the Related Art For example, when moving a so-called moving body such as an emergency evacuation device used for evacuation drilling along a guiding cable, an emergency rope is preliminarily attached to the moving body in order to ensure safety in the event of an abnormality. Passing to prevent dangerous movement.

[0003] However, this conventional measure has a troublesome problem that the length of the emergency cord and the position of the fixed point must be constantly adjusted in accordance with the movement of the moving body in order to prevent dangerous movement.

[0004]

SUMMARY OF THE INVENTION The present invention focuses on such a problem, and an object of the present invention is to provide an emergency stop device capable of urgently stopping a moving body when necessary, regardless of the position of the moving body. I do.

[0005]

A description will be given with reference to FIGS. The emergency stop device for a guiding rope according to the present invention rolls the guiding wheel 20 provided in the base frame 80 to the guiding rope 10,
The base frame 80 is movable along the guiding cable 10, and the inner surface of the substrate 81 constituting the base frame 80 is widened upward and has the inclined surface 36 on the guiding cable 10 side.
And a stopper pin 60 penetrating the sliding guide.
Is provided, and a sliding spring 70 for pulling the slider 40 upward is provided in the base frame 80, and is engaged with the stopper pin 60. A trigger 50 is provided, which is stopped at the lower end position against the pulling force of the sliding spring 70 and is connected to the emergency rope 55, and in an emergency, the emergency rope 55 is pulled to disengage the trigger 50 from the stopper pin 60, and The slider 40 is moved by the moving element 40, and the sliding element 40 is pressed against the guiding cable 10 to stop.

[0006]

1 to 4 show an embodiment of an emergency stop device for a guiding cable according to the present invention. This device is
The four guide wheels 2 are mounted on the upper and lower sides of the base frame 80, and are attached to the evacuation evacuation device used during the evacuation drill.
0 is rotatably fixed, the guide wheel 20 is rolled on the guide cable 10, and the base frame 80 is movable along the guide cable 10.

Further, a base frame 80 is formed, and a sliding guide 30 is fixedly projected with a screw 31 on an inner surface of a substrate 81 having a vertical hole 82 formed in a vertical direction. This sliding guide 30
Is inclined toward the guiding rope 10 as the width increases upward.
6 and parallel to the inclined surface 36, an inclined groove 33 is formed in both side walls 35, and a long hole 32 is formed in the center portion thereof so as to face the vertical hole 82 of the substrate 81. ing. By forming the inclined surface 36, a long piece 38 is formed on the upper surface of the sliding guide 30, and a short piece 37 is formed on the lower surface.
Is formed.

The slider 40 is provided in the base frame 80. The sliding element 40 is provided with a sliding part 34 inserted from its leg 41 into the inclined groove 33 of the sliding guide 30 with a fixing screw 42.
And protrude inward.
2 and a stopper pin 60 penetrating through the vertical hole 82 is projected.

A sliding spring 70 for pulling the slider 40 upward is provided in the base frame 80. The sliding spring 70 has its upper end engaged with a lock 71 provided on the base frame 80, and its lower end protruding from the slider 40.
Is engaged. On the outside of the base frame 80, a trigger 50 for engaging the stopper pin 60 to stop the slider 40 at the lower end position against the pulling force of the sliding spring 70 is rotatably provided. The trigger 50 is supported by a support shaft 53 on a bracket 83 projecting from the substrate 81, and is urged toward the stopper pin 60 by the elastic force of the butterfly coil spring 54, and the hook portion 51 is engaged with the stopper pin 60. Combine. The locking hole 52 of the trigger 50 has
The emergency rope 55 attached to the moving body is connected.

The operation of the guide line emergency stop device will be described. In normal times, the guide wheel 20 rolls in contact with the guide cable 10 and moves along the guide cable 10. Guide wheel 2
Since four 0s are provided on each of the upper and lower sides of the base frame 80, they can move in a stable posture without coming off from the guiding cable 10.

In this state, if a trainee wearing a mobile body falls, for example, the emergency rope 55 attached to the mobile body will fall.
Is pulled downward, so that the trigger 50 rotates against the elasticity of the butterfly coil spring 54 and comes off the stopper pin 60. Thereby, the slider 40 is pulled upward by the sliding spring 70 and moves upward. At this time, since the sliding portion 34 of the slider 40 is inserted into the inclined groove 33 of the sliding guide 30, the slider 40 is guided toward the guiding cable 10 and strongly presses the slider 40, The device stops descending due to the frictional force at that time. As a result, a sudden drop of the moving body is prevented, and safety is ensured.

[0012]

Since the present invention is configured as described above, it does not cause any obstacle when the moving body moves normally along the guiding cable 10, and when the moving body needs an emergency stop, it immediately has a large frictional force. And the moving body can be stopped. Therefore, safety is secured and it is extremely useful.
