Pseudo-oblique fully-mechanized coal mining hydraulic bracket

Abstract

The invention provides a pseudo-oblique fully-mechanized coal mining hydraulic bracket, which comprises a base, a bridge, upright posts, a back connecting rod, a back connecting rod side protection plate, a shield beam, a shield beam side protection plate and a top beam, wherein the front end of the base is a bevel edge; the bevel edge of the front end of the base is parallel to a scraper conveyer; the bridge is parallel to the bevel edge of the front end of the base, and is fixed on the base; the upright posts are parallel to the bridge; the back part of the back connecting rod is an oblique plane; the back part of the shield beam is an oblique plane; the back ends of the top beam is a bevel edge; one end, which is connected with the top beam, of the shield beam is a bevel edge; on a pseudo-oblique coal mining working surface, an oblique channel is formed between the bridge and the scraper conveyer; seen from a direction from an air way to a machine way, the shield beam and the back connecting rod on the hydraulic bracket on the pseudo-oblique coal mining working surface are arranged into two regular oblique planes. The pseudo-oblique fully-mechanized coal mining hydraulic bracket has the beneficial effects that people can pass conveniently, the bracket is easy to adjust, the hydraulic bracket is effectively prevented from sliding downwards, and gangues are prevented from entering the bracket from a mined-out area; the pseudo-oblique fully-mechanized coal mining hydraulic bracket has very high adaptability to the environment of the pseudo-oblique coal mining working surface.

Description

technical field [0001] The invention relates to coal mine support equipment, in particular to a pseudo-inclined fully mechanized mining hydraulic support. Background technique [0002] Hydraulic support is a fully mechanized mining support equipment developed on the basis of friction props and single hydraulic props. It is widely used in coal mining faces, but it is rarely seen in pseudo-inclined coal mining faces The use of hydraulic supports for production is mainly because there are many problems in the use of hydraulic supports in pseudo-inclined coal mining faces. The frame type of existing hydraulic supports is not suitable for the layout of pseudo-inclined coal mining faces. Automatic shifting leads to difficulty in recovering after sliding, anti-skid and anti-fall jacks are not easy to install, hydraulic support is difficult to adjust, personnel cannot walk smoothly in the hydraulic support of the working face, etc., gangue in the gob area is easy to escape into the ...

[0002] Hydraulic support is a fully mechanized mining support equipment developed on the basis of friction props and single hydraulic props. It is widely used in coal mining faces, but it is rarely seen in pseudo-inclined coal mining faces The use of hydraulic supports for production is mainly because there are many problems in the use of hydraulic supports in pseudo-inclined coal mining faces. The frame type of existing hydraulic supports is not suitable for the layout of pseudo-inclined coal mining faces. Automatic shifting leads to difficulty in recovering after sliding, anti-skid and anti-fall jacks are not easy to install, hydraulic support is difficult to adjust, personnel cannot walk smoothly in the hydraulic support of the working face, etc., gangue in the gob area is easy to escape into the support, etc., at this stage The key technologies to solve these problems have not achieved breakthroughs, leading to the abandonment of fully mechanized mining hydraulic supports in the pseudo-inclined coal mining face, and the use of traditional coal mining methods with relatively low productivity, such as mining with pseudo-inclined flexible cover supports. The method has low degree of mechanization, high labor intensity, low safety factor, and low output. Therefore, the invention of a hydraulic support that can adapt to the production of pseudo-inclined coal mining face is very important for expanding the comprehensive mechanized production of coal mines and improving the working conditions of workers.
