Abstract

The invention discloses a coal mine underground support convenient to disassemble and assemble. The coal mine underground support comprises a first supporting rod and a second supporting rod, a cross rod is hinged to the upper end of the first supporting rod through a rotating shaft, a clamping plate is fixedly connected to the other end of the cross rod, a linear through hole is formed in the side, adjacent to the cross rod, of the clamping plate, a cross-shaped through hole matched with the clamping plate is formed in the upper end of the second supporting rod, a first clamping ring and a second clamping ring are fixed to the rod wall of the second supporting rod, a first clamping rod is arranged on the first clamping ring, the first clamping rod is movably sleeved with a first cylindrical ring, the first cylindrical ring is located in the first clamping ring and movably connected with the first clamping ring, a second clamping rod is arranged on the second clamping ring, the second clamping rod is movably sleeved with a second cylindrical ring, the second cylindrical ring is located in the second clamping ring and movably connected with the second clamping ring, and the lower end of the first supporting rod and the lower end of the second supporting rod are fixedly connected with a supporting seat. The support is convenient to disassemble, assemble and operate, labor-saving, simple and convenient to manufacture and cost-saving.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a coal mine underground support that is easy to assemble and disassemble. Background technique [0002] Support is the general term for the components or other measures taken to support, strengthen or cover the surrounding rock for the stability and construction safety after the excavation of the underground chamber. When the traditional mining method is used for construction, the support types include retaining pillars and erecting supports. There are three types of rock reinforcement, and when the new Austrian method is used for construction, it can be divided into two types: temporary support and permanent support according to the supporting effect, including spray anchor support, steel and wood support, concrete lining, grouting support, etc. Type, the support is an essential equipment in the coal mining process, the support can effectively prevent the collapse of...
