Description

Technical Field

[0001] The utility model relates to the field of mining equipment, in particular to anti-collapse support equipment for mines. Background Art

[0002] Mining anti-collapse support equipment is one of the important facilities used to ensure the safety of underground mining operations. Its main function is to support the mine tunnels, mining working faces and prevent rock collapse, thereby ensuring the safety of personnel and smooth operation during the mining process.

[0003] Most of the existing mine support structures are frame supports, which have a small range of mine support in actual use, resulting in the inner walls of the mine between the frames being exposed. The exposed inner walls of the mine are often vibrated by the construction work of the workers, causing broken stones to fall from the exposed inner walls of the mine, thereby affecting the safety of the workers passing through the support equipment. In addition, most mine support equipment requires the parts to be brought into the mine for assembly, and the installation process is very cumbersome.

[0004] Therefore, in order to solve the problem that the above-mentioned mine anti-collapse support equipment is cumbersome to install and use, and its anti-fall range is very limited, and it is difficult to flexibly adjust according to the needs of different mine protection, a new type of mine anti-collapse support equipment is developed. The support frame is connected to the base body, and a pulley is installed on the base to push the equipment into the mine, which can save a lot of installation process. By adding hydraulic rods and steel mesh to the support frame, the output end of the hydraulic rod extends to support the steel mesh and flips and unfolds, effectively improving the protection range of the equipment.
