Abstract

The invention relates to a steel wire rope looseness and breakage alarming device. The steel wire rope looseness and breakage alarming device comprises a first fixing device and a second fixing device both fixed on a vertically arranged steel wire rope, wherein a long threaded rod is also arranged between the first fixing device and the second fixing device; a movable contact is arranged on the top end of the long threaded rod; a third fixing device is also arranged above the long threaded rod; a short threaded rod is arranged on the third fixing device; a fixed contact is arranged on the tail end of the short threaded rod; the fixed contact is arranged on the upper part of a movable contact; a gap is formed between the fixed contact and the movable contact; the fixed contact and the movable contact are connected to a console respectively through control lines. When a steel wire rope is loosened or broken accidentally, the fixed contact and the movable contact are in contact to trigger safety protection devices of crane equipment such as an elevator and a stereoscopic parking garage to lighten damage caused by accidents. The steel wire rope looseness and breakage alarming device has the characteristics of simple installation, a capability of discovering looseness and breakage of the steel wire rope as early as possible, high sensitivity and the like.

Description

[0001] technical field [0002] The invention belongs to the technical field of hoisting equipment safety alarms, in particular to a wire rope slack and break alarm device. [0003] Background technique [0004] During the operation of lifting equipment such as elevators and three-dimensional parking garages, the vertical lifting is basically achieved by pulling the steel wire rope. If it can be discovered in time, it may cause irreparable losses; although this type of equipment is generally equipped with a brake device, the device does not work immediately at the moment of the accident, and by the time it works, an accident may have occurred. Therefore, it is necessary to design a kind of wire rope slack rope and fracture alarm safety device. When an accident occurs, timely braking of lifting equipment such as elevators and three-dimensional parking garages will help reduce the accident rate of such equipment. [0005] Contents of the invention [0006] The technical p...
