Abstract

The invention discloses an anti-impact coal mine supporting frame. The anti-impact coal mine supporting frame comprises a bottom rod and an inclined supporting rod angle adjusting unit, wherein two inclined supporting rod height adjusting units are installed at the top of the bottom rod through the inclined supporting rod angle adjusting unit, the two sides of the bottom of the top rod are movablyconnected with the tops of the two inclined supporting rods through hinge supports correspondingly, a top supporting unit is installed at the top of the top rod through a transverse buffering unit, avertical buffer unit is mounted between the inner side of the top support unit and the transverse buffer unit, the inclined supporting rod angle adjusting unit comprises a strip-shaped groove, firstsliding blocks, a hydraulic telescopic rod and an adjusting base, the strip-shaped groove is formed in the bottom rod, and the two ends of the strip-shaped groove are connected with the two first sliding blocks in a sliding mode. According to the anti-impact coal mine supporting frame, the height can be adjusted in a large-size mode, the inclination degree of inclined supporting rods can be adjusted to finely adjust the height, the supporting strength of the supporting frame is enhanced, impact buffering can be provided in all directions, buffering sufficiency is guaranteed, the buffering effect is good, and supporting of a coal mine is facilitated.

Description

technical field [0001] The invention relates to the technical field of coal mine support, in particular to an anti-shock coal mine support frame and a use method. Background technique [0002] In coal mines, support frames are used for support, but deep mining is an inevitable trend in the development of the coal industry. The composition and structure characteristics, deformation and failure characteristics, energy release characteristics and engineering response characteristics of deep coal and rock mass are obviously different from shallow coal and rock mass. Induce rock burst disasters, causing serious underground damage and casualties; [0003] Now, in order to avoid impact low-pressure disasters, shock-resistant support frames are used, but these support frames are generally buffered by hydraulic cylinders, which are not sufficiently buffered and have limited buffer angles, so the impact mitigation effect is poor, which is not conducive to the safety of coal mines. su...
