Description

Technical Field

[0001] This utility model belongs to the field of tunnel measurement technology, and specifically relates to a tunnel measurement device. Background Technology

[0002] Tunnels are expensive to build and difficult to construct. After the tunnel is completed or during routine maintenance, it is necessary to measure the curvature of the tunnel top to check for deformation so that any potential dangers can be dealt with in a timely manner. This is where tunnel measuring devices come in.

[0003] Existing tunnel surveying devices are typically mounted on mobile equipment and use sensors that rotate at a certain angle to detect the inner wall of a tunnel. If a deformation is detected, the rotation stops and an alarm is triggered, allowing users to know the approximate location. However, because tunnels are often very tall, when a problem is detected, it is necessary to use a lifting device to move the personnel to the potentially deformed area, mark it, or handle it directly. This process is time-consuming and affects subsequent tunnel measurements, thus presenting certain shortcomings. Therefore, we propose a tunnel surveying device. Utility Model Content

[0023] The spraying assembly 4 includes a pump 41, a discharge pipe 42, a connecting pipe 43, a retaining ring 44, a nozzle 45, and a connecting ring 46.

[0026] The working principle of the tunnel measuring device provided by this utility model is as follows: First, the electric telescopic rod 14 is activated, causing the storage tank 2 to move upward. The downward movement of the storage tank 2 drives the guide wheel 55 to move upward and fit against the inner wall of the tunnel. After fitting, the guide wheel 55 is further compressed, causing the connecting frame 54 to move downward. The downward movement of the connecting frame 54 drives the two top rods 63 to move, causing the two top rods 63 to separate from the two pressure sensors 62. After separation, the second motor 13 is activated, causing the connecting bar 12 to rotate. The rotation of the connecting bar 12 drives the guide wheel 55 to move along the inner wall of the tunnel. During its movement, if a depression or subsidence is detected in the inner wall of the tunnel, the guide wheel 55 will be compressed. The agitator 55 moves up or down, and during its movement, the corresponding push rod 63 also moves to press the corresponding pressure sensor 62. At this time, the PLC controller 10 will control the pump 41 to work and spray the paint inside the storage tank 2 through the two nozzles 45 onto the damaged area of ​​the tunnel to mark it. After marking, it will be convenient for users to repair it later. When marking, the first motor 71 can be started to make the gear 72 rotate. The rotation of the gear 72 drives the gear ring 73 to rotate, the rotation of the gear ring 73 drives the fixed ring 44 to rotate, and the rotation of the fixed ring 44 drives the two nozzles 45 to rotate. During the rotation, the paint can be evenly sprayed around the tunnel defect.

[0027] It is worth noting that the PLC controller 10 disclosed in the above embodiments is specifically a Siemens S7-200. The first motor and the second motor 13 can be selected as 1LE0003 three-phase asynchronous motors. The electric telescopic rod 14, the material pump 41 and the pressure sensor 62 can be freely configured according to the actual application scenario. The PLC controller 10 controls the electric telescopic rod 14, the material pump 41 and the first motor and the second motor 13 using methods commonly used in the prior art.
