Description

TECHNICAL FIELD

[0001] The utility model relates to a detection device, especially a detection device for catenary and tunnel clearance parameters. BACKGROUND

[0002] The geometric parameters of the catenary and the tunnel clearance parameters are parameters that must be detected during the construction, maintenance and operation of the railway, and directly affect the safe operation of the track traffic. The geometric parameters of the catenary are detected by a catenary geometric parameter detection device, and the tunnel clearance parameters are detected by a tunnel clearance parameter detection device. The two detection devices cannot be used universally. However, the staff needs to use the two detection devices at intervals during the detection process, and thus needs to take two sets of detection devices to the work site. Taking too many detection devices to the site is inconvenient and increases the labor intensity of the staff. In addition, the replacement of the detection devices for detecting different parameters also increases the work of the detection personnel. For example, the positioning of the detection device on the track and the adjustment of the detection device require time, which undoubtedly reduces the detection efficiency. SUMMARY
