The supporting top plate can be flexibly replaced according to the needs of the support arc at the top of the tunnel. When replacing, the mounting bolts are unscrewed and the mounting sleeve at the bottom of the supporting top plate is removed from the mounting frame. This structure realizes the functions of convenient and flexible support and improved support strength.

[0017] (3) By setting an adjusting rod, a fixing plate, a splicing block, a splicing slot and a fixing bolt, the arc support structure and the support rod can be separated. When separating, first unscrew the fixing bolt, and then move the splicing block at the top of the adjusting rod out of the splicing slot. The separated arc support structure and the support rod can be used independently and are easy to transport. The movable base at the bottom of the fixing plate makes it easy to push it to move. This structure realizes the function of easy disassembly and transportation. Attached Figure Description

A second arc-shaped support plate 9 is fixedly connected to the top of the fixed plate 5. A first arc-shaped support plate 7 is set above the second arc-shaped support plate 9. A reinforcing support rod 8 and a mounting frame 10 are fixedly welded between the first arc-shaped support plate 7 and the second arc-shaped support plate 9. A supporting top plate 6 is installed at the top of the mounting frame 10. A reinforcing base 14 is fixedly connected to the bottom of the support rod 1. An adjusting rod 3 can slide inside the support rod 1.

[0025] The front end of the support rod 1 is provided with a motor bracket, the drive motor 2 is mounted on the motor bracket, the rear end of the positioning block 13 is in contact with the front end of the adjusting rod 3, and the positioning block 13 is in arc-shaped engagement with the positioning protrusion 4.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the support device can adjust the support height according to the tunnel height. When adjusting, the hydraulic cylinder 12 is activated, and the hydraulic cylinder 12 pushes the fixed plate 5 upward until the support top plate 6 supports the top of the tunnel. Then, the drive motor 2 drives the positioning rod 15 to rotate, so that the positioning block 13 moves to the bottom of the corresponding positioning protrusion 4, which can limit and fix the position of the adjusting rod 3. Then the hydraulic cylinder 12 can be reset. When adjusting the height of the fixed plate 5 again, the positioning block 13 needs to be moved away from the bottom of the positioning protrusion 4.

[0027] A mounting sleeve 19 is fixedly connected to the bottom end of the supporting top plate 6. A mounting bolt 20 is provided at the front end of the mounting sleeve 19. A mounting hole is provided on the mounting frame 10. The mounting sleeve 19 is fitted over the outside of the mounting frame 10, and the mounting bolt 20 is installed inside the mounting hole of the mounting frame 10.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the first arc-shaped support plate 7 and the second arc-shaped support plate 9 improve the strength of the support through a double support structure. The reinforcing support rods 8 regularly installed between the first arc-shaped support plate 7 and the second arc-shaped support plate 9 enhance the compressive strength of the support device. The support top plate 6 can be flexibly replaced according to the requirements of the support curvature at the top of the tunnel. When replacing, simply unscrew the mounting bolts 20 and remove the mounting sleeve 19 at the bottom of the support top plate 6 from the mounting frame 10.

The separated arc-shaped support structure and the support rod 1 can be used independently and are easy to transport. The movable base 11 at the bottom of the fixing plate 5 makes it easy to push and move.

[0031] Working principle: In use, the supporting top plate 6 of this utility model can be used for supporting and protecting the tunnel top. First, the hydraulic cylinder 12 is activated, pushing the fixed plate 5 upwards until the supporting top plate 6 supports the tunnel top. Then, the drive motor 2 drives the positioning rod 15 to rotate, causing the positioning block 13 to move below the corresponding positioning protrusion 4, thus limiting and fixing the position of the adjusting rod 3. Afterwards, the hydraulic cylinder 12 can be reset. When adjusting the height of the fixed plate 5 again, the positioning block 13 needs to be moved away from the bottom of the positioning protrusion 4. The first arc-shaped support plate 7 and the second arc-shaped support plate 9 provide double support. The structure enhances the strength of the support. The reinforcing struts 8, which are regularly installed between the first arc-shaped support plate 7 and the second arc-shaped support plate 9, enhance the compressive strength of the support device. The support top plate 6 can be flexibly replaced according to the requirements of the tunnel top support curvature. The arc-shaped support structure and the support rod 1 can be separated. When separating, first unscrew the fixing bolts 18, and then remove the splicing clip 16 at the top of the adjusting rod 3 from the inside of the splicing clip 17. The separated arc-shaped support structure and the support rod 1 can be used independently and are easy to transport. The movable base 11 at the bottom of the fixing plate 5 makes it easy to push and move. This structure realizes the function of easy disassembly and transportation.
