[0002] A tunnel is an engineering structure buried underground, representing a form of human utilization of underground space. Tunnel construction support devices play a crucial role in tunnel engineering, primarily preventing deformation or collapse of the surrounding rock and ensuring construction safety and stability. However, different tunnels have different heights, and traditional tunnel construction support devices cannot be height-adjusted, creating limitations and hindering flexible application. Furthermore, traditional devices are inconvenient for adjusting the angle of the curved support plates according to the actual conditions of the tunnel, resulting in insufficient support effectiveness. Therefore, designing a new tunnel construction support device is essential. Summary of the Invention

A threaded rod 4 is fixedly connected to the output end of the motor 5. The end of the threaded rod 4 away from the motor 5 is rotatably connected to the side of the fixed plate 3. Multiple moving blocks 9 are threadedly connected to the threaded rod 4. An annular groove 10 is formed on one side of the moving block 9. A sliding rod 11 is slidably connected in the annular groove 10. One end of the sliding rod 11 extends outside the annular groove 10 and a support column 12 is fixedly connected above it. A support plate 15 is fixedly connected to the top of the support column 12. Multiple hydraulic cylinders 16 are fixedly connected to the top surface of the support plate 15. An arc-shaped plate 17 is rotatably connected to the upper end of the hydraulic cylinders 16 via a rotating shaft. The annular groove 10 includes an inclined moving section. The base 1 is equipped with a horizontally upper limit support column 12. The angle of the arc plate 17 can be adjusted according to the actual situation of the tunnel via a rotating shaft, which can better support the tunnel. By starting the motor 5, the motor 5 drives the threaded rod 4 to rotate. Since the moving block 9 is threadedly connected to the threaded rod 4, the threaded rod 4 will drive the moving block 9 to move. When the moving block 9 moves, the sliding rod 11 will slide in the annular groove 10. When the sliding rod 11 moves to the waist of the annular groove 10, the sliding rod 11 will drive the support column 12 to adjust its height. The support column 12 will drive the support plate 15 to adjust its height, thereby achieving the purpose of adjusting the height of the support device, so that the arc plate 17 lifts the tunnel and plays a supporting role. It is suitable for tunnels of different heights.
[0027] The base 1 has casters 2 with locking mechanisms rotatably connected to the four corners of its bottom surface. By setting the casters 2, the device can be moved easily, improving its convenience. A motor base 6 is fixedly connected to one side of the top surface of the base 1. The motor 5 is fixedly connected above the motor base 6. A sliding block 8 is fixedly connected to the bottom surface of the moving block 9. A sliding groove 7 is opened on the top surface of the base 1. The sliding block 8 extends into the sliding groove 7 and is slidably connected to the sliding groove 7. A connecting column 14 is fixedly connected to the top surface of the base 1 at the position corresponding to the support column 12. A horizontal column 18 is fixedly connected to one side of the connecting column 14. A connecting block 13 is fixedly connected to the end of the horizontal column 18 away from the connecting column 14. A sliding through hole 20 is opened on the connecting block 13. The support column 12 passes through the sliding through hole 20 and is slidably connected to the sliding through hole 20. A threaded hole 19 that matches the threaded rod 4 is opened on the moving block 9. The annular groove 10 is a triangular annular groove 10.
[0028] Working principle: By starting the motor 5, the motor 5 drives the threaded rod 4 to rotate. Since the moving block 9 is threadedly connected to the threaded rod 4, the threaded rod 4 will drive the moving block 9 to move. When the moving block 9 moves, the sliding rod 11 will slide in the annular groove 10. When the sliding rod 11 moves to the waist of the annular groove 10, the sliding rod 11 will drive the support column 12 to adjust its height. The support column 12 will drive the support plate 15 to adjust its height, thereby achieving the purpose of adjusting the height of the support device. This allows the arc plate 17 to lift the tunnel and provide support. It is suitable for tunnels of different heights. By setting the hydraulic cylinder 16, the height of the arc plate 17 can be adjusted independently. By using the rotating shaft, the angle of the arc plate 17 can be adjusted according to the actual situation of the tunnel, which can better support the tunnel and has strong practicality. By setting the universal wheels 2, the device can be easily moved, improving its convenience.
