Problems solved by technology

[0003] Facing the top area of ​​a large-scale mine, the area of ​​the support area at the front beam end of the traditional hydraulic support is fixed. A large amount of dust will be generated during the support process, therefore, it is necessary to provide a new hydraulic support to solve the above technical problems

Abstract

The invention belongs to the technical field of support frames, and particularly relates to a hydraulic support frame. The support frame comprises a base, a support moving structure, a rotating spraying and dust reduction structure, a lifting support structure, and an adjusting support structure. The adjusting support structure is connected with the lifting support structure, the adjusting supportstructure comprises a second pin shaft, a swing rod, a support plate, a front beam frame, third hydraulic cylinders, an extension plate, a fourth hydraulic cylinder, a cushion block and a second telescopic sleeve, the front beam frame is installed at the top end of the lifting support structure, the support plate is connected to the rear side face of the top end of the front beam frame, and the support plate is rotatably connected with the swing rod through the second pin shaft. The hydraulic support frame has the advantages that through the arrangement of the adjusting support structure, twosymmetrically arranged third hydraulic cylinders are opened, and the extension plate can be driven to move in an extending mode inside the front beam frame, so that the overall widths of the extension plate and the front beam frame are increased, the contact area with the top part in a mine cave is increased, the area of a support area can be increased, and the protection effect is increased.

Description

technical field [0001] The invention belongs to the field of support technology, in particular to a hydraulic support. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. Mining face mine pressure acts on the hydraulic support in the form of external load. In the mechanical system of the interaction between the hydraulic support and the surrounding rock of the mining face, if the resultant force of the supports of the hydraulic support and the resultant force of the external load acting on the hydraulic support by the roof are exactly on the same line, the hydraulic support is very suitable for the surrounding rock of the mining face . [0003] Facing the top area of ​​a large-scale mine, the area of ​​the support area at the front beam end of the traditional hydraulic support is fixed. A large amount of dust will be generated during the support process, therefore, it is necessary to provide a new h...
