Self-moving advanced supporting hydraulic bracket with side guard plate

Abstract

The invention discloses a self-moving advanced supporting hydraulic bracket with a side guard plate. The bracket comprises two brackets, a wireless monitoring device and a hydraulic system. The two brackets are arranged front and back. Each of the brackets comprises a base and a top beam, a four-connecting rod mechanism connecting the top beam and the base and a synchronous hydraulic flexible column. The top beams and the bases are connected through hydraulic telescopic oil cylinders, and the bases of the two brackets are correspondingly connected through the hydraulic telescopic oil cylinders; each of the brackets also comprises a top lateral wall plate and a bottom lateral wall plate, and the top lateral wall plate and the bottom lateral wall plate are separately connected to the outer sides of the top beam and the base through a plurality of horizontal jack units which arranged up and down. The self-moving advanced supporting hydraulic bracket disclosed by the invention can effectively support two lateral walls of a lane in advanced support of a coal work lane, so that distortion and breakage of the two lateral walls of the lane can be reduced.

Description

technical field [0001] The invention belongs to the field of underground coal mining equipment in coal mines, and in particular relates to a self-moving advanced support hydraulic support with side guard plates under the condition that the two sides of the roadway are under high pressure and easy to deform. Background technique [0002] In the process of coal mining, with the continuous mining of coal resources, the shallow coal resources have been exhausted, so it is necessary to mine deep coal resources. However, with the deep mining, we have to face problems such as a sharp increase in mine pressure, especially In some deep mines, the roadway deformation of the working face is serious, the two gangs are severely damaged, and the roof and floor are also damaged to varying degrees, especially in the advanced section of the working face roadway, there is serious roadway deformation, which seriously affects the working face. The advancement of coal mines will affect the norma...

[0002] In the process of coal mining, with the continuous mining of coal resources, the shallow coal resources have been exhausted, so it is necessary to mine deep coal resources. However, with the deep mining, we have to face problems such as a sharp increase in mine pressure, especially In some deep mines, the roadway deformation of the working face is serious, the two gangs are severely damaged, and the roof and floor are also damaged to varying degrees, especially in the advanced section of the working face roadway, there is serious roadway deformation, which seriously affects the working face. The advancement of coal mines will affect the normal coal mining work, and there will be serious safety hazards, affecting the personal safety of workers, as well as damage to roadway equipment, resulting in huge economic losses

[0003] However, among the many advanced hydraulic supports, there are few equipments that can effectively support the two sides of the roadway. Basically, the roof and the bottom plate are considered. consideration and solution
