Mine slope protection frame convenient to disassemble and reuse

Abstract

The invention discloses a mine slope protection frame convenient to disassemble and reuse. The mine slope protection frame comprises a first baffle plate and a fixing block; sliding grooves are formedin the first baffle plate and are connected with a second baffle plate through a sliding block; blocking pieces are arranged at the bottom end of the second baffle plate; a limiting hole is formed inthe lower part of the second baffle plate; a limiting block is arranged in the limiting hole; a first spring is connected with one end of the limiting block; the fixing block is arranged at the lowerend of the first baffle plate; a fixing hole is formed in the fixing block and connected with a fixing column mutually; connecting blocks are mounted at the bottom end of the first baffle plate and mutually connected with first struts; and second springs are mounted at the bottom ends of the first struts and connected with second struts mutually. According to the mine slope protection frame convenient to disassemble and reuse, the shapes of the first baffle plate and the second baffle plate are arc-shaped, so that after falling on the first baffle plate and the second baffle, crushed stones are not accumulated on the first baffle plate and the second baffle but slide to the ground, so that a device is not loaded.

Description

technical field [0001] The invention relates to the technical field of mine protection, in particular to a mine slope protection frame which is convenient to be disassembled and reused. Background technique [0002] When people are mining, they will protect the surroundings of the mine to prevent the gravel from falling and hurting the on-site staff. The general mine protection device is built with a steel frame, which has poor stability and is easily squeezed by the gravel. The resistance to cushioning is small, and the steel frame is bulky, so it is time-consuming and laborious to assemble. [0003] Therefore, we proposed a mine slope protection frame that is easy to disassemble and reuse, so as to solve the problem mentioned above. The general mine protection device will be built with a steel frame, which has poor stability, is easily squeezed by gravel, and has a small resistance to buffering. , and the steel frame is bulky, and it is time-consuming and labor-intensive ...
