Description
Technical field:
The utility model relates to mechanical field, particularly relates to iron tower of power transmission line jacking system, particularly a kind of safety lock for iron tower of power transmission line jacking system.
Background technology:
UHV transmission line steel tower is widely used in electrical network.The installation and maintenance of UHV transmission line equipment often needs workmen to climb steel tower.In prior art, at steel tower top hanging steel rope, utilize a climbing mechanism to carry hanging basket and walk on a steel cord, climb steel tower to help workmen and tool material.In addition, steel tower top is also hung with safety rope, and hanging basket is provided with safety lock, and safety rope, through safety lock, so that when steel rope surprisingly ruptures, utilizes safety lock to be fixed on safety rope by hanging basket.Safety lock is by centrifugal and swing arm type two kinds of forms, and be physical construction, its course of reaction is slower.
Summary of the invention:
The purpose of this utility model is to provide a kind of safety lock for iron tower of power transmission line jacking system, and the described this safety lock for iron tower of power transmission line jacking system will solve in prior art for the centrifugal of hanging basket or the slower technical matters of swing arm type safety lock reactor.
This safety lock for iron tower of power transmission line jacking system of the present utility model, comprise a lock body, wherein, a safety rope passage is provided with in described lock body, a radial direction through hole is provided with in the sidewall of described safety rope passage, a briquetting is provided with in described radial direction through hole, sliding pair is set between described briquetting and lock body, first toggle link and second toggle link is provided with in lock body, one end and the lock body of the first described toggle link are hinged, one end of the second described toggle link and the rear end of briquetting hinged, the other end of the first toggle link and the other end of the second toggle link hinged, an electromagnet is provided with in lock body, described electromagnet includes an armature, described armature is connected with the articulated section of the first toggle link and the second toggle link by a pipe link, a power supply and a control circuit board is provided with in lock body, described control circuit board is provided with an acceleration pick-up and a micro controller system, described acceleration pick-up is connected with the input interface of described micro controller system, the output interface of micro controller system is connected with the control circuit in a relay, pull up circuit in described relay and described power supply and electromagnet are connected in series.
Principle of work of the present utility model is: lock body is fixedly installed on hanging basket, and safety rope is through the safety rope passage in lock body.During hanging basket accidental falling, acceleration pick-up detects the signal that acceleration/accel increases, micro controller system is by the action of Control electromagnet, electromagnet armature promotes the articulated section of the first toggle link and the second toggle link by pipe link, the first toggle link and the second toggle link is changed into linear state from case of bending, briquetting is released by the second toggle link in safety rope passage, is locked on safety rope by lock body.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model utilizes acceleration pick-up, micro controller system and electromagnetic mechanism to control the action of safety rope briquetting in lock body, substantially increases the speed of response of safety lock.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the safety lock for iron tower of power transmission line jacking system of the present utility model.
Fig. 2 is the schematic diagram for the control circuit in the safety lock of iron tower of power transmission line jacking system of the present utility model.
