Description

Technical Field

[0001] The utility model relates to the technical field of tunnel monitoring, and more specifically, to a flip-type monitoring and measuring observation pile for tunnel monitoring. Background Art

[0002] Tunnel monitoring and measurement is to use various measuring instruments and tools to measure the changes of surrounding rock and the working state of the support structure during the tunnel excavation process, provide safety information on the stability of the surrounding rock and the reliability of the support structure in a timely manner, and foresee accidents and dangers. During the tunnel monitoring and measurement process, one of the key steps is to arrange monitoring and measurement points. In order to obtain measurement data better, it is often necessary to arrange multiple monitoring and measurement piles at the same section at certain intervals according to the grade of tunnel surrounding rock.

[0003] After retrieval, the utility model patent with the publication number of CN215003592U discloses a tunnel monitoring and measurement pile, which includes a measuring pile body and a protection component. The protection component includes a support body and a baffle. The measuring pile body includes a monitoring rod and a monitoring head. The support body can be embedded in the primary support. The baffle blocks the open side of the support body. The outer surface of the baffle is flush with the outer surface of the primary support. Spray concrete on the primary support, and the support body is fixed in the primary support. Remove the concrete outside the baffle, and a concave protection space is formed inside the support body; drill a hole in the direction of the surrounding rock through the through hole, pass the first end of the monitoring rod through the through hole and fix it in the surrounding rock, the second end is located inside the support body, and the monitoring head is installed at the second end of the monitoring rod. When the baffle is buckled, the monitoring head is located in the protection cavity formed by the baffle and the support rod, and the external machinery cannot damage the internal monitoring head, solving the problem that the external machinery is easy to damage the monitoring head caused by the current external leakage of the monitoring head.

[0004] However, the above patent still has the following deficiencies: the baffle needs to be manually opened to expose the reflective sticker wrapped in the cavity, and the number and angle of the observation piles are relatively cumbersome during detection; in addition, when the reflective sticker is placed outside, dust is likely to adhere to it, affecting the measurement of the reflective sticker by the total station. For this reason, we propose a flip-type monitoring and measuring observation pile for tunnel monitoring. Summary of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a flip-type monitoring and measuring observation pile for tunnel monitoring.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

An installation seat is arranged on the inner side surface of the flip - plate. A reflective sticker is fixedly connected to the outer side surface of the installation seat. A cleaning mechanism is arranged in the inner cavity of the observation pile box.

[0008] As a preferred scheme of the utility model, the cleaning mechanism includes an electric push rod fixedly installed in the inner cavity of the observation pile box. The output end of the electric push rod is fixedly connected with a U - shaped frame. A rotating roller is rotatably connected to the inner side of the U - shaped frame. A plurality of cleaning cloths are fixedly connected to the outer side of the rotating roller. A second motor is fixedly installed on the top surface of the U - shaped frame.

[0009] As a preferred scheme of the utility model, a controller is fixedly installed in the inner cavity of the observation pile box. The controller is electrically connected to the electric push rod, the second motor and the first motor respectively.

[0010] As a preferred scheme of the utility model, a storage battery is arranged on the inner wall of the observation pile box. The storage battery is electrically connected to the controller, the electric push rod, the second motor and the first motor respectively.

[0011] As a preferred scheme of the utility model, the inner wall of the rotation groove is in fit with the outer side surface of the flip - plate. The top and bottom of the inner cavity of the rotation groove are arc grooves. The top and bottom ends of the flip - plate are arc surfaces.

[0012] As a preferred scheme of the utility model, the position of the rotating roller is aligned with the position of the reflective sticker.

[0013] Compared with the prior art, the advantages of the utility model are as follows:

[0014] (1) In the utility model, the first motor is controlled by the controller, so that the first motor drives the flip - plate to flip.

When not monitoring and measuring, the reflective sticker is stored in the observation pile box. And the first motor is used to automatically control the flip - plate, avoiding manual rotation and adjustment of the reflective sticker by manpower, and improving its practicability.

[0015] (2) In the present utility model, after the reflective sticker is stored in the inner cavity of the observation pile box, the second motor drives the rotating roller and the cleaning cloth to rotate, and the electric push rod drives the cleaning cloth to contact the reflective sticker, so that the rotating cleaning cloth cleans the outer side of the reflective sticker, in order to clean the dust on the reflective sticker, ensure the cleanliness of the surface of the reflective sticker, ensure that it can be accurately captured and monitored by the total station during subsequent monitoring, and improve the working quality of the flip - type monitoring and measuring observation pile for tunnel monitoring.
