When various operations are carried out through the tunnels, temporary support equipment is needed to support the inside of the tunnels to ensure safety during mining operations.

[0003] For example, the publication number CN219472129U discloses a tunnel support device, which belongs to the technical field of tunnel support, and includes two columns and a top beam located at the top of the columns, a base plate is installed at the bottom of the columns, and the top beam is arched. The utility model includes two columns and a top beam located at the top of the columns, a base plate is installed at the bottom of the columns, the top beam is arched, through holes are provided at both ends of the top beam and at both ends of the columns, and the top beam and the columns are detachably connected. The utility model is easy to install. During installation, the columns on one side are first positioned, and the columns are fixed by the base, and then the columns on the other side are installed. After the installation is completed, one end of the top beam is first connected and fixed to the top of the column, and then the other end is fixed. The installation is simple and convenient, and has high stability and support effect. The curvature of the top beam can be adjusted by the provided threaded tightening assembly, and the top beam can be conveniently installed by adjustment, thereby improving the convenience of installation.

A side baffle (9) is provided on the lower surface of the first support plate (2), and the inner wall of the side baffle (9) is connected to a fixed air bag (10), so that when the top plate (8) rises, the fixed air bag (10) is squeezed, so that the gas inside the fixed air bag (10) enters the fixed cavity (12) through the connecting pipe (11), so that the amount of gas inside the fixed cavity (12) increases, thereby pushing the movable block (13) to move, and the movable block (13) drives the positioning plate (14) to move together, so that the positioning plate (14) slides and engages in the positioning groove (15), so that the connection between the first support plate (2) and the second support plate (3) can be more firmly established; Step 3: When the mounting plate (6) rises, it also drives the fixing plate (7) to rise, and the rising of the fixing plate (7) drives the first vertical plate (16) to rise. A second vertical plate (17) is arranged above the first vertical plate (16), and the top end of the second vertical plate (17) is fixed to the second support plate (3), and the first vertical plate (16) and the second vertical plate (17) are slidably connected, so when the fixing plate (7) drives the first vertical plate (16) to rise, the first vertical plate (16) slides along the second vertical plate (17), so that the second support plate (3) can be always supported; Step 4: When the fixed plate (7) rises, it drives the partition plate (18) to rise, and the partition plate (18) drives the first rack (19) to rise together. The first rack (19) drives the first gear (21) to rotate counterclockwise, and the first gear (21) drives the rotating shaft (20) to rotate counterclockwise. Since the first gear (21) and the second gear (22) are meshingly connected, when the first gear (21) rotates counterclockwise, it drives the second gear (22) to rotate clockwise, so that the shaft inside the second gear (22) drives the third gear (23) to rotate clockwise through the transmission belt, wherein the third gear (23) and the second rack (24) on the upper surface of the push plate (25) are meshingly connected, so that the second rack (24) and the push plate (25) are moved closer to the inner wall of the second support plate (3), and the second support plate (3) is supported and reinforced by the push plate (25); Step 5: A reinforcing plate (31) is also installed on the inner wall of the tunnel body (1), and reinforcing rods (32) are provided on both the upper and lower sides of the reinforcing plate (31), and the upper reinforcing rod (32) is fixed to the cross plate (4) through the connecting plate (33), so that the cross plate (4) can be supported under the action of the reinforcing rod (32), so that the device has better stability when in use and is also convenient for disassembly and assembly operations.
