Problems solved by technology

[0002] Before the present invention was proposed, in the detection of complex modern railway tunnels, the safety and stability of tunnel vaults were generally detected by manual hand-held geological radar detection methods. Affect the inspection quality of the tunnel
At the same time, since the ground radar must be in contact with the tunnel vault during detection, the ground radar will be damaged if the operator is not careful.
Moreover, since the catenary is arranged on the top of the tunnel, there is a potential safety hazard that the ground radar or the operator will collide with or hook the catenary

Abstract

The invention discloses a tunnel arch crown detection device, which includes a geological radar, an extension mechanism and a base, wherein the geological radar is installed on the base through the extension mechanism; the extension mechanism includes a guiding rail, a guiding rail sliding block, a support rod and a driving assembly; the guiding rail is vertically arranged on the base; the support rod is installed on the guiding rail through the guiding rail sliding block in a sliding manner; the driving assembly drives the support rod to slide on the guiding rail; and the geological radar is installed at the top end of the support rod through a buffering mechanism enabling the geological radar to be elastically contacted with the tunnel wall. The tunnel arch crown detection device prevents the geological radar from being held manually by hands for detection through the additionally-arranged extension mechanism, improves the safety and stability in detection, and is suitable for tunnel detection.

Description

technical field [0001] The invention relates to a tunnel detection device, in particular to a tunnel vault detection device. Background technique [0002] Before the present invention was proposed, in the detection of complex modern railway tunnels in operation, the safety and stability of tunnel vaults were generally detected by manual hand-held geological radar detection methods. Affect the detection quality of the tunnel. At the same time, since the ground radar must be in contact with the tunnel vault during detection, the ground radar will be damaged if the operator is not careful. Moreover, since the catenary is arranged on the top of the tunnel, there is a potential safety hazard that the ground radar or the operator will collide with or hook the catenary. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a tunnel vault detection device with simple structu...
