Problems solved by technology

[0003] The existing detection devices are mainly simple lining thickness detectors, which are generally hand-held and require staff to carry out actual pick-up and detection work. Generally, several points need to be taken at different heights and different positions in the tunnel for detection work. , when it is necessary to carry out detection work at a high position, it is necessary for the staff to use the lifting device to lift up and reach the high place to carry out the detection work with a hand-held detector. Such an operation has a certain potential safety hazard and has been used for detection Work, the staff will get tired easily and consume a lot of manpower

Embodiment

[0037] Embodiment: A self-coupling tunnel lining detection device provided by the present invention includes a detector support 1 and a mounting base 10, a support rod 20 is fixedly installed on the bottom surface of the mounting base 10, and a fixing plate is fixedly installed on the bottom surface of the support rod 20 30. In the process of tunnel lining detection, move the device to the position to be detected. In order to reach the height to be detected, start the hydraulic rod 43, and the output end of the hydraulic rod 43 drives the scissor lifting frame 41 to move vertically along the fixed point. Upward linear movement, at the same time one end of the scissor lift 41 moves along the sliding plate 44 to achieve the effect of supporting the lift. When it moves to an appropriate position, stop and start the hydraulic rod 43, and the hydraulic rod 43 can also support the scissor lift 41 Keep at a fixed height without changing. When the height is adjusted, start the driving ...

Abstract

The invention provides a self-coupling tunnel lining detection device which comprises a fixing plate, a supporting rod arranged above the fixing plate and a movable lifting mechanism arranged below the fixing plate, and a detection mechanism is arranged on the supporting rod. The detection mechanism comprises a rotating ring rotationally arranged on the supporting rod and a detachable detector support arranged on the rotating ring, and the supporting rod is provided with a rotating mechanism used for driving the rotating ring to rotate; a connecting rod is arranged on the rotating ring, a connecting assembly matching the connecting rod in an inserted mode is arranged on the side, facing the rotating ring, of the detector support, and an arc-shaped elastic plate is arranged on the other side of the detector support. The height of the detector support is adjusted through the lifting mechanism, proper adjustment can be conducted according to the needed operation height, a worker does notneed to reach the high position to operate the detector for detection any more, and safety is relatively higher.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to a self-coupling tunnel lining detection device. Background technique [0002] Tunnel lining specifically refers to the permanent structure that supports and maintains the long-term stability and durability of the tunnel. The purpose of constructing the tunnel lining in the tunnel is to support and maintain the stability of the tunnel, maintain the space required for train operation, and prevent the weathering of surrounding rocks. And remove the influence of groundwater, etc. Therefore, if a tunnel wants to be put into use for a long time and ensure the safety performance of the tunnel, it is necessary to carry out tunnel lining work. At the same time, the tunnel lining must also have sufficient strength, durability and certain resistance. Freezing, impermeability and erosion resistance, so that such a tunnel can cope with the harsh natural environment outs...
