Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0019] figure 2 It is a structural schematic diagram of a hydraulic prop used in a hydraulic support system according to the present invention. like figure 2 As shown, the anti-shock relief hydraulic prop consists of a live column 1, a cylinder body 2, a safety valve 3, an energy-absorbing transition section 4, an energy-absorbing anti-shock relief member 5, and a movable column bottom 6 as a whole. Among them, the energy-absorbing anti-shock relief component 5 is placed in the movable column bottom 6, one end of the energy-absorbing transition section 4 is placed in one end of the movable column bottom 6, and the other end of the energy-absorbing transition section 4 is embedded in the hydraulic single pillar 7 Inside. The live column 1 is placed in the cylinder bod...

Abstract

The invention discloses a hydraulic prop for a hydraulic support system, which comprises a hydraulic single prop (7). The hydraulic prop for the hydraulic support system is characterized by further comprising an energy absorption transitional section (4), an energy absorption scour prevention avoidance component (5) and a movable prop bottom (6). The energy absorption scour prevention avoidance component (5) is placed in the movable prop bottom (6), one end of the energy absorption transitional section (4) is sleeved in one end of the movable prop bottom (6), and the other end of the energy absorption transitional section (4) is embedded in the hydraulic single prop (7).

Description

technical field [0001] The invention relates to a hydraulic prop, in particular to a hydraulic prop used in a hydraulic support system. Background technique [0002] Rockburst (also known as mine earthquake or rockburst) is one of the major disasters in coal mines, and it is the instantaneous concentrated release of a huge elastic energy induced by mining. The huge elastic energy released instantly by rock burst can seriously damage the transportation, ventilation roadways and coal mining face, cause the roof to sink instantly and the floor to rise instantly, subvert the production equipment in a large area, damage the support, and cause gas Gushing out, even accidents such as gas explosions, and causing casualties. According to statistics, my country has more than 100 coal mines with rock burst at present. [0003] At present, the methods of preventing and controlling rock burst disasters at home and abroad are mainly divided into three types: one is regional preventive m...
