[0002] Tunnel monitoring and measurement technology is an important part of modern tunnel construction and an important means of monitoring the stability of surrounding rock and structure. When carrying out tunnel construction, especially for tunnels with surrounding rock above Grade IV, monitoring and measurement is indispensable. It is a key process to ensure the safety and rationality of initial support and determine the time for secondary lining construction. It also has important guiding significance for the connection of various construction processes in the tunnel.

[0044] The operation process of the clamping mechanism is as follows: first, manually rotate the limit dial 55, and the limit dial 55 rotates through the rotating shaft 54 ​​to drive the rotating column 49 and the half rack 51 to rotate, and the rotation of the half rack 51 drives the rack plate 52 to move and squeeze the spring 2 53, and the rotating column 49 rotates through the arc groove 50 to squeeze and push the protrusion 48 to move, and the protrusion 48 drives the side plate 47, the clamping block 45 and the limit rod 46 to move, so that the limit rod 46 moves and is stored in the through cavity to avoid affecting the rotation of the driving dial 43, and then manually rotate the driving dial 43, and the driving dial 43 rotates to drive the threaded rod 42 to rotate, and the threaded rod 42 can enter the active cavity 32 under the action of the threaded hole while rotating, and the threaded rod 42 can push the active cavity 32 while being screwed into the active cavity 32 The sliding seat 1 38 moves linearly, and the sliding seat 1 38 can drive the sliding seat 2 39 to move synchronously while moving. The sliding seat 1 38 and the sliding seat 2 39 drive the extrusion block 1 40 and the extrusion block 2 41 on their respective outer surfaces to move while moving. The extrusion block 1 40 squeezes the extrusion groove 1 35 on the sliding frame 1 33 while moving, and the extrusion block 2 41 squeezes the extrusion groove 2 37 on the sliding frame 2 36 while moving, so that the sliding frame 1 33 and the sliding frame 2 36 can realize the outward expansion movement synchronously. The sliding frame 1 33 drives the pad 56 to be inserted into the groove 12 while moving, and the end of the sliding frame 2 36 penetrates to the outside of the fixed seat 3. At this time, the two plug seats 17 on the connecting seat 6 are inserted into the groove 12. In this process , the slot 18 on the plug-in seat 17 is plugged into the fixed bevel seat 14. During the plugging process, the bevel end of the bevel card seat 23 is squeezed together with the fixed bevel seat 14, thereby pushing the bevel card seat 23 to be stored and moved into the movable groove 19. While the bevel card seat 23 is stored and moved, it will squeeze the bevel hole 10 through the convex rod 1 24, thereby pushing the rotating ring 28 to rotate. The rotating ring 28 rotates and squeezes the convex rod 27 through the bevel hole 21. The convex rod 27 drives the sliding block 25 to move and squeeze the spring 1 26 until the end of the plug-in seat 17 is squeezed together with the pad 56. At this time, the connecting seat 6 is also squeezed together with the protruding sliding frame 2 36, and the bevel card seat 23 on the inner wall of the slot 18 also crosses the fixed bevel seat 14. At this time, Under the action of spring 1 26, the rotating ring 28 resets and rotates through the inclined hole 2 31 and the inclined hole 1 30 to push the inclined surface clamping seat 23 to reset and extend, so that the flat surface of the inclined surface clamping seat 23 is squeezed together with the end of the fixed inclined surface seat 14, forming a clamping fixation between the plug seat 17 and the fixed inclined surface seat 14. At this time, the driving turntable 43 also rotates to the outer surface of the fixed seat 3, and the limiting hole 44 on the driving turntable 43 is also located on the same axis as the limiting rod 46. At this time, the limiting turntable 55 is released. Under the action of spring 2 53, the rack plate 52 pushes the half rack 51 and the rotating column 49 to reset and rotate. The rotating column 49 resets and rotates through the arc groove 50 to squeeze and push the protrusion 48, so that the side plate 47, the clamping block 45 and the limiting rod 46 move linearly.Then the limiting rod 46 extends out of the fixing seat 3 and is clamped in the limiting hole 44 on the driving rotating disk 43 to achieve clamping and fixing of the driving rotating disk 43.

[0045] When it is necessary to disassemble the connecting seat 6 with the reflective sheet 10 and the hook 8 from the fixing seat 3, at this time, first rotate the limit dial 55, the limit dial 55 rotates through the limit assembly to drive the limit rod 46 to move, so that the limit rod 46 is stored and moved into the active cavity 32, and the limit on the driving dial 43 is released. Then, the driving dial 43 is rotated in the opposite direction to drive the sliding seat 1 38 and the sliding seat 2 39 to reset and move, thereby driving the sliding frame 1 33 and the pad 56 as well as the sliding frame 2 36 to reset and move into the active cavity 32. At this time, the connecting seat 6 with the reflective sheet 10 and the hook 8 is disassembled. The seat 6 can drive the plug-in seat 17 to be further inserted into the groove 12, so that the inclined clamping seat 23 on the plug-in seat 17 is inserted into the annular groove 16 on the sliding inclined seat 15. Then, the plug-in seat 17 is pulled out of the groove 12, and the inclined clamping seat 23 drives the sliding inclined seat 15 to slide on the fixed rod 13 by clamping the annular groove 16, so that the sliding inclined seat 15 and the fixed inclined seat 14 are temporarily connected together to form a whole, so that the movement of the plug-in seat 17 can be separated from the fixed inclined seat 14 and move to the outside of the groove 12.

[0046] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
