Coal moving resistance device of main inclined shaft loading point

Abstract

The invention specifically discloses a coal moving resistance device of a main inclined shaft loading point, and solves the problems that loading point coal movement has potential safety hazards, so that the main inclined shaft cannot carry out normal production due to paralysis. The left side and the right side of a belt frame are provided with frame-type coal blocking frames; the rear end of each coal blocking frame is provided with a coal blocking cover; the outer end surfaces of the two coal blocking frames are provided with side door planks; the upper end surfaces of the two coal blocking frames are provided with upper cover plates; the inner sides of the upper ends of the two coal blocking frames are provided with coal blocking plates; the upper end of each coal blocking frame is provided with an inclined cover plate; a belt on the front side of a tail roller is provided with a coal cleaning device; the side wall of a coal discharging pipe of a coal feeder is spliced with a spile; the spile is connected with a push-pull oil cylinder; one row of coal sealing steel needles arranged at an interval is inserted into the side wall of the coal discharging pipe; an operating platform is provided with an escape platform; a counter weight box body is arranged out of a clump weight; the outer side of a sump is provided with a blocking frame; the front side of an air door is provided with a blocking wall; a first operating platform is provided with a first escape platform. According to the coal moving resistance device, effective safety protection is carried out, and maintenance amount is obviously lowered.

Description

technical field [0001] The invention relates to an underground safety protection device for coal mines, in particular to an anti-foaming coal device for a loading point of a main inclined shaft. Background technique [0002] The output of raw coal in coal mines has been increasing year by year. After the belt system has been speeded up, the pressure on the main inclined shaft has been increased, which often results in the overflow of the loading point at the tail of the main inclined shaft and the phenomenon of water and coal slime. Coal mine production caused great losses. [0003] The main hazards of burning coal at the loading point are as follows: 1. The impact force of burning coal is large, and once out of control, the feeding port and the frame will be deformed by impact; The belt around and at the tail is basically blocked and cannot operate normally; 3. Once the pulverized coal is formed, it will directly endanger the life safety of the workers near the feeding por...
