Mechanical supporting structure for coal mining

Abstract

The invention discloses a mechanical supporting structure for coal mining. The mechanical supporting structure comprises a fixing frame, a supporting unit and a protecting unit, wherein a controller is arranged in the middle of the bottom end of the fixing frame, and adjusting units are arranged at the left end and the right end of the front side face of the fixing frame correspondingly; the supporting unit comprises sliding rods, inserting holes, fixing shells, clamping holes, elastic inserting blocks and supporting rods; the two sliding rods are slidably connected with a through groove in the middle of the fixing frame, and the inserting holes are evenly distributed in the front side faces of the sliding rods; the fixing shells are arranged on the outer sides of the bottom ends of the sliding rods, and the bottom ends of the fixing shells are slidably connected with the top ends of the supporting rods; the clamping holes are formed in the bottom ends of the front side faces of the fixing shells, and the elastic inserting blocks are arrayed on the front side faces of the supporting rods and connected with the clamping holes in a clamped mode; and fixing units are arranged at the bottom ends of the outer side faces of the two supporting rods correspondingly, and a filtering unit is arranged on the inner side face of the fixing shell on the right side. The mechanical supporting structure for coal mining is easy to use, convenient to adjust and high in practicability and safety.

Description

technical field [0001] The invention relates to the technical field of coal mine support devices, in particular to a mechanical support structure for coal mine mining. Background technique [0002] Coal mine is an important source of energy and an important industrial raw material in our country. Our country is rich in coal reserves, and coal mining is an important industry in our country. Since open-pit coal mines only account for a small part of coal mine resources, it is necessary to dig coal mines underground. When mining coal mines, a large number of roadways will be generated. These roadways are excavated due to the underlying supports. Lack of necessary support is prone to collapse events, so manual laying of support equipment is required for support. The traditional supporting equipment is mainly supported by wooden boards. Due to the limited compressive capacity of the wooden boards and the inconvenient adjustment of the support strength, landslides are still prone...

AI Technical Summary

Problems solved by technology

The traditional supporting equipment is mainly supported by wooden boards. Due to the limited compressive capacity of wooden boards and the inconvenient adjustment of the support strength, landslides are still prone to occur. Generally, steel pipes are used for support, so the height cannot be adjusted according to the usage. They are all composed of steel pipes. There are large gaps between the steel pipes. Falling rocks passing through the gaps will also cause harm to personnel, and there is no device for detecting the gas concentration, which leads to failure to timely remind when the gas concentration is too high. evacuation
