[0037] Specifically, first start double-head motor 2, drive shaft 3 starts to rotate, at this time, the first limiting block 4 can provide effective support for the shaft 3, when the shaft 3 is in a rotating state, will prompt the first connecting rod 5 to expand the rotation with the shaft 3 as the axis, in this rotating process, the first rotating column 6 will move accordingly, and when the first rotating column 6 moves, the second connecting rod 7 will start to rotate with the first rotating column 6 as the axis, at the same time, the rotating action of the second connecting rod 7 will lift the second rotating column 8, so that the second rotating column 8 moves, when the second rotating column 8 moves, the first connecting block 9 will also move under its driving, and then push the first protection plate 13 to move, in the process of moving the first protection plate 13, due to the existence of the second connecting block 12, the first protection plate 13 will rotate around the second connecting block 12 as the fulcrum, this rotating process will make the first connecting block 9 rotate around the second rotating column 8 as the axis, so that the first protection plate 13 gradually stands up, in the process of the first protection plate 13 standing up, it will also drive the second connecting block 12 to rotate around the third rotating column 11 as the axis, to ensure that the first protection plate 13 can be erected smoothly, so that the device can be used to protect the surrounding when in use, and can be retracted when not in use, so that the first protection plate 13 is in a horizontal state with the support platform 1, reducing the occupied space and preventing the measurement path from being blocked.

[0038] When starting double-head motor 2 and driving the shaft 3 to start rotating, the first rotating rod 14 will rotate around the shaft 3 as the axis, due to the rotation of the first rotating rod 14, it will exert a downward force on the second rotating rod 15, so that the second rotating rod 15 moves downward, and the downward movement of the second rotating rod 15 will also drive the sliding block 16 to move, in this process, the first fixed block 17 can not only ensure that the direction of the sliding block 16 movement remains fixed, but also effectively prevent the sliding block 16 from being accidentally detached and causing the entire device to fail, when the sliding block 16 moves downward, it will exert a downward pushing force on the auxiliary plate 18, prompting the auxiliary plate 18 to move downward, until the auxiliary plate 18 is in complete contact with the ground, and the bottom surface of the auxiliary plate 18 and the bottom surface of the support platform 1 are on the same horizontal line, increasing the contact area with the ground, so that the support platform 1 will not shake left and right.

[0039] Please refer to the accompanying drawings Figure 3 -attached drawings Figure 5 The fixed assembly comprises a ground nail 19, the outer wall of the ground nail 19 is slidingly connected in the inside of the auxiliary plate 18, and the ground nail 19 is arranged on both sides of the auxiliary plate 18.

[0040] Specifically, by means of tools, two ground nails 19 are nailed into the ground and fixed, which can effectively fix the support platform 1 at a specific position, thereby avoiding displacement of the support platform 1 caused by impact force and vibration generated by explosion, and preventing the protection from being invalid.

[0041] Please refer to the accompanying drawings Figure 2 , the accompanying drawings Figure 6 and the accompanying drawings Figure 7 , the first protection plate 13 is rotatably connected with a lead screw 20, the outer wall of the lead screw 20 is fixedly connected with a rotating disc 21, and the first protection plate 13 is internally provided with an inner cavity 29. The outer wall of the lead screw 20 is threadedly connected with a traveling block 22, and the traveling block 22 is rotatably connected with a limiting column 23. The outer wall of the limiting column 23 is fixedly connected with a third connecting rod 24, and the outer wall of the third connecting rod 24 is fixedly connected with an H-shaped column 25. The outer wall of the H-shaped column 25 is fixedly connected with a base 26, and the outer wall of the base 26 is fixedly connected with a second fixed block 27. The outer wall of the second fixed block 27 is fixedly connected with a second protection plate 28. The outer wall of the second protection plate 28 is slidably connected to the inner wall of the inner cavity 29, and the outer wall of the traveling block 22 is slidably connected to the inner wall of the inner cavity 29. The lead screw 20 is provided with two reverse threads.

[0042] Specifically, the support platform 1 is first placed stably on the ground, then the rotating disc 21 is manually rotated, and the rotation of the rotating disc 21 drives the lead screw 20 to rotate. During the rotation of the lead screw 20, due to the threaded transmission relationship between the lead screw 20 and the traveling block 22, and the traveling block 22 is provided with two reverse threads, and the outer wall of the traveling block 22 is tightly fitted with and can slide along the inner wall of the inner cavity 29 of the first protection plate 13, it can be ensured that the traveling block 22 will only move up and down along the inner wall of the inner cavity 29, and will not rotate, so that the traveling blocks 22 on the upper and lower sides will move to the middle position under the rotation of the lead screw 20. When the traveling block 22 starts to move, the limiting column 23 connected thereto also moves, thereby driving the third connecting rod 24 to rotate around the H-shaped column 25 as the axis. Since the length of the third connecting rod 24 is fixed, during its rotation, a pushing force is generated on the H-shaped column 25, thereby pushing the H-shaped column 25 to move, and the movement of the H-shaped column 25 drives the upper and lower bases 26 connected thereto to move. When the two bases 26 move, they simultaneously apply outward pushing force to the two second fixed blocks 27, thereby driving the second protection plate 28 to move outward and expand, which can gradually expand the second protection plate 28, and finally make the device have the ability to adapt to different shapes and sizes of tunnel sections, greatly enhancing the versatility of the device.

[0043] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
