Frame type stopper of ramp of underground mine

Abstract

The invention relates to a stopper, particularly to a ramp stopper and belongs to the mine production equipment field. The frame type stopper of a ramp of an underground mine comprises stopper plates; one ends of the stopper plates are in hinged connection with an anchor rod which is fixed on the top wall of the ramp; one side of the stopper plates, which has the same ascending direction with the ramp, is provided with pulley groups which are fixed on the top wall of the ramp through the anchor rod; the two front and rear pulley groups are connected through a steel wire rope; and two ends of the steel wire rope are respectively connected with the two front and rear stopper plates. The frame type stopper of the ramp of the underground mine has the advantages of performing integral stopping when a tramcar slides on the premise of guaranteeing unobstructed traffic of the tramcar on the ramp, avoiding conditions such as derail or wheel damage of the tramcar and being good in stopping effect.

Description

technical field [0001] The invention relates to a car stopper, in particular to a car stopper for a ramp, belonging to the field of mine production equipment. Background technique [0002] During the transportation of the mine car in the underground mine, after entering the ramp, due to factors such as the weight of the mine car and the large slope gradient, once the traction wire rope breaks or other special circumstances occur, the mine car will slide, which is likely to cause equipment damage or personnel. casualties. In order to avoid the occurrence of such safety accidents, it is generally necessary to install a vehicle arrester on the track, especially on the ramp. Most of the existing vehicle arresters are the opposite wheels or axles that block the mine car. This method can achieve a certain extent. However, when the slope of the ramp is relatively large and the self-weight of the mine car is large, the effect of stopping the car is not good, and it is easy to cause...
