A vehicle-mounted tunnel full-section shape detection device and method

Abstract

The invention discloses a vehicle-mounted tunnel full section shape detection device and a vehicle-mounted tunnel full section shape detection method. An object platform is arranged at the top of a detection vehicle and is connected with the detection vehicle through an object platform supporting seat, and a moving groove is formed in the top of the detection vehicle; the object platform supporting seat is embedded inside the moving groove and can make rotational movement or horizontally move along the moving groove, and automatic object platform regulating systems are symmetrically arranged in the middle parts of the two sides of the object platform; a stepping movable control system is arranged on the object platform, and a full section shape detection instrument is fixed on the stepping movable control system; the full section shape detection instrument is driven by the stepping movable control system to move along the object platform to complete measurement.

Description

technical field [0001] The invention relates to tunnel section detection technology, in particular to a vehicle-mounted tunnel full-section shape detection device and method. Background technique [0002] In tunnel engineering, measuring instruments are used very frequently, some of which are cumbersome to operate and require manual adjustment, which is time-consuming and labor-intensive, and is not easy to carry. The profiler is mainly used for tunnel section detection during tunnel excavation, railway tunnel passage limit detection, etc. During the measurement process, the profiler has the function of measuring the current section and the front section, etc., which requires manual leveling. The function of measuring the current section is to measure the section (inner contour) or limit of the current position of the instrument perpendicular to the tunnel axis. The function of measuring the front section is to measure the section at the preset distance in front of the pos...

AI Technical Summary

Problems solved by technology

When using the function of measuring the front section to measure the section at the preset distance from the front and rear of the instrument perpendicular to the axis of the tunnel, the accuracy of measuring the front and rear sections is slightly lower than that of the current section. When it is necessary to accurately detect the current section where the instrument is located If you need to use the current cross-section measurement function, you need to re-move the instrument to the current cross-section, and manually re-level the instrument for measurement, causing inconvenience

When using the function of measuring the front section, different meters can be set to complete the detection of different sections in the front, and the same number of sections can be detected in the reverse direction, but continuous measurement of all sections in the whole space cannot be carried out during the measurement process
