[0002] During the construction of a mined tunnel, to ensure safety, the initial support structure must be constructed immediately after excavating a certain length (0.5m - 2m). And after constructing the initial support structure, it is often necessary to clean the surface of the tunnel contour and inspect the lining for diseases, that is, scan for lining defects.

Among them, the turntable includes: a fixed base plate, a main shaft, and a rotatable cover plate. The fixed base plate is vertically arranged, and its central axis is horizontally arranged in the front - rear direction. A main shaft is coaxially arranged at its center. On its rear - end side wall, and near the edge, a concave annular gear centered on the main shaft is opened; the fixed base plate can rotate around the main shaft; the rotatable cover plate is a columnar disk body, with an open front end and a closed rear end, coaxially buckled on the fixed base plate, and the rear end passes through the main shaft; an opening for the distal end of the boom to extend out is opened on the edge shell of the rotatable cover plate. This tunnel contour walking device installs a corresponding defect scanning device or mechanical device at the distal end of the boom according to the operation requirements to process the lining, avoiding high - altitude operations by personnel, with good safety and improved construction efficiency; however, it still has the following defects:
