Ground-rising automatic buckle anti-sports car barrier

Abstract

The invention discloses a ground-rising automatic buckling and anti-sliding arrester, comprising a swing shaft, a swing arm and support steel pipes. The ground-rising automatic buckling and anti-sliding arrester is characterized in that a stop net rack is arranged between two groups of the support steel pipes and provided with a notch for accommodating a steel wire rope; the stop net rack at two sides of the notch is provided with a plurality of left buckles and a plurality of right buckles, which are matched with one another; the left buckles and the right buckles are respectively fixed on different buckle transmission shafts; the buckle transmission shafts are rotatably fixed on the stop net rack; the combination and separation states of the left buckles and the right buckles can be realized by rotating the buckle transmission shafts. With adoption of a buckle traction mechanism provided by the invention, the normally closed ground-rising arrester, which cannot be used to a haulage roadway of a winch hauled by using the steel wire rope, can become reality. Through the traction and connection of the left buckles and the right buckles, the strength of the stop net rack is greatly increased and the intercepting reliability is ensured. And meanwhile, the ground-rising automatic buckling and anti-sliding arrester has the advantages of flexible interception, small destructiveness, lifting linkage of the left buckles, the right buckles and the arrester, convenience in realizing automation, stable and reliable working and the like.

Description

technical field [0001] The invention relates to a ground-rising automatic buckle anti-sports car barrier, in particular to a ground-rising automatic buckle anti-sports car barrier which can be normally closed. Background technique [0002] In the "Coal Mine Safety Regulations" published by the State Administration of Work Safety, it is clearly stipulated that the following regulations must be observed when using string vehicles to lift in inclined shafts: "In inclined shafts, install vehicles that can interrupt the rope and uncouple preventive device", and this device must be normally closed. In coal mine production, the lifting and handling of materials and equipment are solved through the auxiliary transportation of inclined lanes. This technical measure has been widely used. The lifting of the inclined lane is mainly realized by the winch pulling the tractor or the transport material truck through the wire rope traction. Since the steel wire rope must always run in the...

AI Technical Summary

Problems solved by technology

As far as the existing car barriers are concerned, most of the ground-rising car barriers used in coal mines cannot realize the normally closed type required in the "Coal Mine Safety Regulations", especially for the endless rope winch transportation

As mentioned above, the hoisting of the inclined lane is mainly realized by the winch pulling the tractor or the transport material truck through the wire rope. The wire rope of the traction vehicle almost runs back and forth in the track close to the ground. Closed and in the raised state, the traction wire rope must be lifted up, so that the wire rope cannot perform traction work

For this reason, some car barriers have a notch in the middle part, which can prevent the wire rope from being jacked up, but the result is that the opening end of the car barrier becomes a "cantilever" structure, resulting in a serious weakening of its strength. Bringing extreme uncertainty, leaving a safety hazard in the word "defense" for inclined alley anti-sports cars
