Embodiment 1
[0030] Embodiment 1: The present invention provides a kind of tunnel lining non-destructive testing device, its structure is as follows figure 1 As shown, it includes a swivel caster with brake 2, a workbench 3, a distance fine-tuning component 4, a height adjustment component 5, an automatic knocking component 6 and a host computer with peripherals.
[0031] The said swivel caster with brake 2 is installed on the lower end of the base 3.1 of the workbench 3, and is used to adjust the position of the device in the working state, and lock the brake of the swivel caster with brake for tunnel lining detection, and It is very convenient to move and transfer the device by using universal casters with brakes when detecting the working state.
[0032] The workbench 3 is provided with a base 3.1, an escalator 3.2 and a worktable 3.3, the worktable and the base are used to support the distance fine-tuning assembly 4 installed on the worktable, and the height adjustment assembly 5 and t...
Embodiment 2
[0047] Embodiment 2: The present invention provides a non-destructive testing device for tunnel lining. Its structure, assembly process and testing operation steps are basically the same as those in Embodiment 1, except that the device is fixed on the cylindrical rack bar of the height adjustment assembly 5. It is connected with 4 inclined support rods 5.4 and an automatic knocking assembly 6, which can realize the simultaneous detection of 4 measuring lines in the same tunnel.
Embodiment 3
[0048] Embodiment 3: The present invention provides a tunnel lining non-destructive testing device, the structure of which is the same as that of Embodiment 2, that is, four inclined support rods 5.4 and automatic knocking rods are fixedly connected to the cylindrical rack rod of the height adjustment assembly 5. Hitting assembly 6, the only difference is that 2 such detection devices of the same structure of the present invention are fixed on the same railway engineering vehicle 1 during use, so as to realize the simultaneous detection of 8 measuring lines of single-track railway tunnels.
[0049] The tunnel lining non-destructive testing device of the present invention adopts a modular design, which is convenient to assemble and disassemble, and simple to operate. The detection of the tunnel lining by the device is a non-destructive detection, which has good detection objectivity, a large detection surface, high detection efficiency and reliable detection results.
