Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a tunnel automation monitoring benchmark point fixing structure. Background Art

[0002] At present, whether it is a subway tunnel or a municipal tunnel, when laying out an automated monitoring system, it is necessary to lay out 4 to 8 large prisms outside the deformation zone as reference points for the automated monitoring system. The traditional method is to use an electric drill to drill holes in the tunnel side wall, and then use quick-drying anchor glue to directly fix the connecting rod to the tunnel side wall. The other end is directly plugged into a large prism to complete the reference point installation.

[0003] However, after the completion of the automated monitoring project, all equipment buried in the tunnel needs to be removed according to the owner's requirements. Since the reference point connecting rod is fixed with anchor glue, it can only be removed by cutting. However, this brings new problems: ① Because the connecting rod is made of stainless steel, it is hard and is affected by the skylight time point in the tunnel (usually 3 to 4 hours), the operation efficiency is relatively low; ② The subway tunnel cutting operation also requires the declaration of a fire plan, and the operating personnel need to receive professional training and obtain an operation qualification certificate before they can perform the cutting operation. The process is very cumbersome. Therefore, it is urgent to simplify the installation method of the reference point of the automated system, so the utility model proposes a fixed structure for the reference point of the automated monitoring of the tunnel.

[0026] Working principle: First, insert the embedded part 4 into the tunnel side wall. Through the long groove on the insertion end 15, the embedded part 4 is tightly combined with the tunnel side wall. Fix a large prism on the second end of the connecting rod 1. Thread the second end of the connecting rod 1 with the embedded part 4 to make the second end of the connecting rod 1 tightly fit with the embedded part 4. At this time, a plurality of second inserting blocks 14 are in contact with the sliding groove 6. Then, twist the rotating sleeve 3. The rotating sleeve 3 drives the two first inserting blocks 9 and the two connecting frames 10 to move. The two first inserting blocks 9 slide along the lower end surface of the rotating groove on the connecting rod 1. When the two first inserting blocks 9 respectively move to directly above the two first connecting grooves 5, the two connecting frames 10 jointly drive the second connecting ring 13 to move.

The rotating sleeve 3 drives the second connecting ring 13 to move through the two connecting frames 10. The second connecting ring 13 drives the second inserting blocks 14 to be inserted into the second connecting grooves 7, avoiding the deviation of the large prism caused by the looseness of the combination of the connecting rod 1 and the embedded part 4 due to the vibration generated during construction. When the connecting rod 1 needs to be removed after the construction is completed, pull the rotating sleeve 3. The rotating sleeve 3 drives the first connecting ring 12 to compress the spring 11. The rotating sleeve 3 drives the two first inserting blocks 9 to respectively disengage from the two first connecting grooves 5. At this time, the two first inserting blocks 9 are in contact with the lower end surface of the rotating groove on the connecting rod 1. The rotating sleeve 3 jointly drives the second connecting ring 13 to move through the two connecting frames 10. The second connecting ring 13 drives a plurality of second inserting blocks 14 to respectively disengage from the plurality of second connecting grooves 7. Then, twist the connecting rod 1 to make the connecting rod 1 disengage from the embedded part 4.
