Hydraulic support for mines

Abstract

The invention discloses a hydraulic support for mines. The hydraulic support comprises a top beam, a shielding beam is connected to one side of the top beam, a first side protection plate is arrangedon the shielding beam, a second side protection plate is installed at one side of the first side protection plate, and a column is connected with a hydraulic mechanism through a connecting fastener; aturntable is arranged below the hydraulic mechanism, and fixedly connected to a fixed disc through fixing bolt grooves, a connecting rod is installed at one side of the hydraulic mechanism, a connecting rod supporting rod is installed on the connecting rod, a base is installed below the fixed disc, and a push device is arranged at one side of the base. Compared with the prior art, the hydraulic support has the advantages that by installing the electric-control turntable below a column mechanism, the position of acting force and the fixed-amount supporting position of the column are adjustable, moreover, the hydraulic support is provided with a face guard device and the push device, so that the hydraulic support is more convenient to install and use as a whole, and various mine space problems can be dealt with; the hydraulic support is simple and exquisite in structure, does not have quick-wear parts, and is high in practicability and attractive and elegant in appearance.

Description

technical field [0001] The invention relates to the field of mine supports, in particular to a mine hydraulic support. Background technique [0002] The hydraulic support is a structure used to control the mine pressure of the coal mining face. The mine pressure of the mining face acts on the hydraulic support in the form of external load. The resultant force of the support and the resultant force of the external load acting on the hydraulic support by the roof are exactly on the same line, so the hydraulic support is very suitable for the surrounding rock of this mining face. [0003] There are many kinds of hydraulic supports, which can be divided into shield support, support shield support and support support according to the frame structure; according to the applicable coal seam inclination angle, it can be divided into general working face support and large inclination angle support; according to the applicable mining height, it can be divided into thin coal seam suppor...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that there are many types of supports on the market but their structures and functions are similar. The single-column support has poor interchangeability in complex environments, and it is difficult to meet the operation requirements, while the multi-column support has a complex structure and requires a lot of auxiliary equipment. , which increases the production cost, and if a fault occurs, it will be cumbersome to repair
