Immediate support device for digging machine

Abstract

The invention relates to an in-time supporting device for a fully-mechanized coal mining machine, comprising a pedestal, a top beam, a hydraulic upright post which connects the pedestal and the top beam, side frames which consist of four link mechanisms, and a telescopic connecting beam and a hydraulic cylinder which are hinged between two side frames. The invention adopts the technical key pointsthat: top beams of the side frames adopt front top beams or continuous top beams; the side frames which are arranged in parallel and provided with the front top beams or the continuous top beams arehinged into a front support or a continuous support through an arched beam or a horizontal beam; shun beams are arranged on the arched beam or the horizontal beam at intervals; belt guard beams or telescopic shun beams are arranged between adjacent shun beams. The in-time supporting device for the fully-mechanized coal mining machine effectively solves the problems in the prior art of lagged supporting means, difficult frame movement, requirement of stop operation, low efficiency and so on, is reasonable in structural design, stable in supporting operation, convenient in assembly and disassembly and maintenance, and safe and reliable in use, preferably meets the requirements of matched operation of underworkings and the fully-mechanized coal mining machine, realizes in-time mechanical support of a just exposed roof of a tunneling work surface of a laneway, and shields the fully-mechanized coal mining machine to realize continuous operation.

Description

technical field

[0001] The invention relates to a support device for roadway excavation in mining, in particular to a timely support device for a fully mechanized excavator that can cooperate with a comprehensive mechanized roadheader, which realizes timely mechanization of the roof just exposed during roadway excavation Support and protect the comprehensive excavator to achieve continuous operation. It belongs to the field of mining machinery manufacturing and application. Background technique

[0002] In the current mining, especially in the underground mining of coal mines, the tunneling operation of the roadway is a prerequisite for all other operations. With the widespread use of comprehensive mechanized roadheaders (referred to as "mechanized roadheaders"), the efficiency of roadway excavation has been greatly improved compared with the traditional "drilling and blasting" operation method. However, due to the influence of rock conditions on the roadway roof, the comm...
