Support moving mechanical arm for roadway

Abstract

The invention discloses a support moving mechanical arm for a roadway. The support moving mechanical arm for the roadway solves the problems that in the prior art, roadway roofs are repeatedly supported, the support moving speed is low, operations are complex and operational efficiency is low. The support moving mechanical arm for the roadway comprises a fixed foundation base, a transmission mechanism, a rotating base and a lifting mechanism, wherein the fixed foundation base is arranged at the bottom of the mechanical arm and the lifting mechanism is arranged on the rotating base. According to the technical scheme, the lifting mechanism arranged on the rotating base is composed of a lifting guiding sleeve, lifting hydraulic cylinders and lifting guide rods, a cantilever extensible mechanism composed of cantilever guiding rods, cantilever hydraulic cylinders and cantilever extensible sleeves is perpendicularly fixed at the upper portion of the lifting guide rods, roof supporting hydraulic stand columns with a roof supporting base hinged at the tops are fixed on the rotating base, the rotating base is driven through a rotation driving device and the transmission mechanism to rotate around the center of a rotating shaft. The support moving mechanical arm for the roadway is reasonable in structural design, stable in moving, convenient to operate, safe to use, capable of reducing influences on coal mining production by forepoling operation and beneficial to further improvement of yield per unit of a coal face.

Description

technical field [0001] The invention relates to an auxiliary shifting device for safe operation of a fully mechanized mining face, in particular to an auxiliary moving device used for advance support in the roadway of the working face as the mining progresses while the normal mining operation is in progress. The rack-moving mechanical arm is used for the roadway with auxiliary mechanical forward movement of the support. It belongs to the field of mining machinery manufacturing and application. Background technique [0002] The safety support of the roadway in the fully mechanized mining face mainly adopts U-shaped steel, I-shaped steel metal brackets, anchor rods, anchor nets and other joint support methods. Therefore, it is necessary to strengthen the support at the leading section of the exit of the working face. The widely used advanced support brackets in coal mining face roadways are mostly supported by single hydraulic props combined with metal hinged top beams or lo...
