Gate machine for belt conveyor in coal mine roadway

Abstract

A brake machine for a belt conveyor in a coal mine roadway comprises a machine frame, the top of the machine frame is provided with a top beam in the front-and-back horizontal direction, a plurality of jacks or oil cylinders are arranged below the top beam, the axes of the jacks or the oil cylinders are located in the vertical direction, a base of each jack or a base of a cylinder body of each oil cylinder is hinged to the lower end of a beam in a connected mode, each jack or a piston rod of each oil cylinder is fixedly connected with the top end of an upper belt clamping plate, and an upper soft cushion is fixed at the bottom end of the upper belt clamping plate. A lower belt clamping plate is arranged below the upper belt clamping plate, the plane of the lower belt clamping plate is located in the horizontal direction, a lower soft cushion is fixed at the top end of the lower belt clamping plate, the lower belt clamping plate is fixed on the top of a bottom beam, and the bottom beam is fixed on the machine frame. The brake machine for the belt conveyor in the coal mine roadway has the advantages that the belt conveyor can be fast braked before belt flying or during the belt flying process, the serious fault of the belt conveyor can be avoided, and the normal operation of coal mine production can be ensured.

Description

technical field [0001] The invention relates to a gate for a belt conveyor in a coal mine roadway. Background technique [0002] For belt conveyors that carry belts underground or on the ground, the conventionally designed inclination angle is mostly 15 degrees. When the slope of the coal mine roadway is relatively large, the inclination angle can reach a maximum of 19 degrees. Due to the large and uneven degree of raw coal in the mine , there are many loading points, it is not suitable to use closed pressure belt and tubular belt conveyors; when the belt conveyor, that is, the belt conveyor, has a flying belt, the belt usually breaks away from the driving drum, so even if the driving drum is braked by the braking device If it is stopped, the belt will continue to move, causing serious damage to the belt conveyor equipment, and the coal mine production cannot proceed normally. Contents of the invention [0003] The purpose of the present invention is to provide a belt con...
