Description

Technical Field

[0001] The utility model relates to the technical field of coal mine excavation support structures, in particular to a coal mine excavation support structure. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly strip the surface soil layer to mine coal. This is an open-pit coal mine. Most of my country's coal mines are underground coal mines. When digging in coal mines, most of them will use support structures to reinforce the top of the tunnel to prevent some gravel or soil from falling from the tunnel from time to time to cause harm to the workers.

[0003] Among them, most of the traditional supporting structures are steel structures with a single function, and this type of supporting structure is inconvenient to install or disassemble. At the same time, the steel structure itself is heavy, which increases the difficulty of use for the staff. In addition, the steel structure does not have a height adjustment function, so when the steel structure is repeatedly used, the staff needs to weld and increase the height, or cut and shorten the steel structure, which makes the support cost and difficulty higher. Therefore, there is a defect that it is inconvenient to use the support, and it cannot meet the customer's use needs. For this reason, we propose a coal mine excavation support structure to solve the above problems. Utility Model Content

[0034] Working principle: when it is necessary to reinforce and support the top of the coal mine excavation tunnel, the staff moves the device to the reinforcement support position at the top of the coal mine excavation tunnel through the universal wheel 12, and then the staff rotates the handle 11 in turn, so that the handle 11 drives the stud 901 to rotate and move on the inner surface thread of the movable plate 1, and at the same time, the stud 901 drives the support plate 902 and the anti-skid pad 10 to rotate and move downward to contact the ground, so that the four support plates 902 and the anti-skid pad 10 are used in coordination to support the device and adjust its horizontal state at the same time; then, the staff rotates the driving plate 17, so that the driving plate 17 drives the sleeve 3 to rotate and move upward on the outer surface thread of the screw 2, and at the same time, the sleeve 3 drives the top plate 4 to move upward, so that the top plate 4 drives the movable pipe 8 to slide upward on the outer surface of the support rod 7, and the top plate 4 drives The dynamic spring 5 and the buffer plate 6 move upward and contact with the top of the tunnel, thereby realizing the reinforcement support of the top of the tunnel and adjusting the height of the reinforcement support; when special circumstances such as vibration occur at the top of the tunnel and the device is squeezed, the buffer plate 6 is squeezed and moves downward to compress the spring 5, and the buffer plate 6 drives the guide rod 15 to slide on the inner surface of the slide cylinder 16. At the same time, the spring 5 supports the buffer plate 6 under the reaction force, so that the buffer plate 6 can be buffered and protected when it is squeezed downward, thereby effectively avoiding the breakage and damage of the device. When the reinforcement support of the top of the coal mine excavation tunnel is completed and it needs to be disassembled, the staff can complete the disassembly of the device by performing the above operations in reverse.
