Technical Field

[0001] This utility model relates to the field of real-time thickness detection technology for shotcrete in tunnels, specifically a laser-based real-time thickness detection device for shotcrete in tunnels. Background Technology

[0002] Shotcrete is concrete applied using the spraying method. After shotcrete construction in tunnels, a thickness laser detection device is used to measure the thickness of the shotcrete layer and determine its flatness. However, existing thickness laser detection devices still have shortcomings, specifically: they are inconvenient to install with vibration damping and to perform real-time laser measurement and voice broadcasting of the shotcrete layer thickness on the concrete spraying head. This makes it difficult to measure the thickness of the shotcrete layer in real time and to achieve precise control over the flatness of the shotcrete during construction, thus affecting the construction quality of the shotcrete in tunnels.

[0003] Therefore, it is necessary to design a laser-based real-time thickness detection device for shotcrete in tunnels to solve the problems mentioned in the background technology. Utility Model Content

A laser thickness gauge is embedded on the right side of the main body, and a power supply is installed on the left side. A control panel, a voice announcer, and a display screen are installed on the top of the main body from left to right. A battery and a control processor are installed inside the main body from left to right. A vibration-damping installation structure is provided between the bottom of the main body and the top of the concrete spraying head. The vibration-damping installation structure includes an upper clamp, a lower clamp, a locking assembly, a spring damper, a mounting base, and a limiting rod.

[0007] As a preferred embodiment of this utility model, the control panel is provided with several control buttons, and the control processor is electrically connected to the laser thickness gauge, power supply wiring, control panel, voice broadcaster, display screen, and battery.

[0008] As a preferred embodiment of this utility model, the input pipe end of the concrete spraying head is connected to the output end of the concrete spraying machine.

[0010] As a preferred embodiment of this utility model, the spring shock absorber is installed on the top of the fixed upper hoop, and the top of the spring shock absorber is connected to a mounting base, the top of which is fixedly connected to the bottom of the main body of the detection device.

[0011] As a preferred embodiment of this utility model, the top four corners of the mounting base are embedded and connected to the top of the fixed upper hoop with limit rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting up a detection device main body with a shock-absorbing installation structure, it is easy to install the shock-absorbing sleeve at the concrete spraying head.
