The device's technical solution includes an arc-shaped support plate with support blocks fixedly mounted on both sides of its bottom end, a pressure relief plate fixedly mounted on the bottoms of the two support blocks, and cushion blocks fixedly mounted on both sides of the bottoms of the pressure relief plate. The bottoms of the two cushion blocks are connected to a lifting and adjustment mechanism, and support feet are fixedly mounted on the bottoms of the lifting and adjustment mechanisms. This utility model provides support and reinforcement for tunnel construction and automatically removes soil and gravel that are prone to falling off and loosening, significantly improving the safety of the support device and protecting the lives of relevant personnel.
[0003] The existing support device is not convenient for replacing the support ring. Generally, the support ring and the base are fixed and installed by multiple bolts. If it is necessary to support arches of different diameters, the support ring needs to be replaced. When replacing, tools are needed to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of replacement. Generally, the support ring of the support device has a poor fit with the arch of the mine. The support ring is made according to the diameter of the arch and has a regular shape. However, when the arch is excavated, there will be unevenness. In this way, when installing the support device, there will be a large gap between the support ring and the arch in some places, which affects the stability of the support and the effect of the support. In order to solve the above-mentioned problems, we propose a mine safety support device for mining thick phosphate deposits. Utility Model Content
