Protective device for aerial cableway

Abstract

The invention discloses a protective device for an aerial cableway. The protective device comprises a machine head fixed unit, a machine tail tension weight unit, a person transporting steel wire rope and a capturing brake control unit, wherein the capturing brake control unit comprises a capturing pull rope, a tension spring mechanism and a capturing winch; the capturing winch is arranged at the tail end of an aerial cableway machine, the other end of the capturing pull rope is rolled on a hoisting barrel and can be released, and the hoisting barrel controls the hoisting barrel to release the capturing pull rope through a tensioning sensor arranged on the machine tail tension weight unit; and the person transporting steel wire rope is provided with at least one pawl braking mechanism, and the capturing winch drives a pawl and a rope supporting wheel to work together to clamp the person transporting steel wire rope through releasing the capturing pull rope. The protective device provided by the invention can reliably brake the steel wire rope in time so as to block a hanging seat in the case of a galloping accident of the aerial cableway; if the person transporting steel wire rope suddenly breaks when the aerial cableway operates, the protective device can reliably capture the person transporting steel wire rope in time, and the protective device can prevent passengers from falling when the person transporting steel wire rope is broken.

Description

technical field [0001] The invention relates to a protection device for an overhead cableway, in particular to a comprehensive protection device for catching broken wire ropes of the aerial cableway, braking a flying car and blocking a seat in a flying car. Background technique [0002] At present, in some specific environments, it is necessary to use aerial ropeways to transport people, but the existing aerial ropeways do not have a complete and reliable safety protection system, and because the use of aerial ropeway units is not well maintained, the safety protection of the ropeway is not enough. Reliability and imperfection have been greatly improved, resulting in repeated accidents of injuries caused by aerial ropeways. For example, the "November 28, 2010 Lianhuashan Coal Mine Accident in Tai'an City" was due to a power failure, and the occupants in the downward direction quickly slid down under the action of gravity, resulting in a speeding phenomenon, causing the occur...

AI Technical Summary

Problems solved by technology

[0004] 1. The above-mentioned broken rope protection device can only realize the arrest of broken rope, but does not consider the occupant injury accident caused by the ropeway speeding, and the safety is not ideal

[0005] 2. Moreover, the braking power of the above-mentioned broken rope protection device only comes from the tail tension counterweight, which pulls the tail device through the pulley under the action of gravity, which leads to the cableway with long lines and many rope-break prevention mechanical grippers. On the other hand, it is prone to defects such as insufficient braking force, long reaction time, and poor reliability.

[0006] 3. In addition, when the occupant rides the rope grip on the hanging chair, the normal passage of the occupant is often affected by the obstruction of the anti-broken mechanical gripper.
