Tunnel lining quality detection mechanical hand

Abstract

The invention discloses a tunnel lining quality detection mechanical hand, and relates to the field of tunnel lining quality detection equipment. The tunnel lining quality detection mechanical hand comprises a base, a universal joint, a floating antenna box device and two rotation telescopic arm mechanisms; each rotation telescopic arm mechanism comprises a rotation seat and a telescopic arm, and one end of the telescopic arm is rotatably connected with the rotation seat; the rotation seat of the first rotation telescopic arm mechanism is rotatably connected with the other end of the telescopic arm of the second rotation telescopic arm mechanism, and a rotary shaft of the rotation seat is perpendicular to a rotary shaft of the telescopic arm of the first rotation telescopic arm mechanism; and the rotation seat of the second rotation telescopic arm mechanism is rotatably connected with the base, and a rotary shaft of the rotation seat is perpendicular to a rotary shaft of the telescopic arm of the second rotation telescopic arm mechanism. The mechanical hand can be used for detecting the tunnel lining quality by carrying with a geological radar antenna, and the detection mode that a radar antenna is lifted by manpower in the prior art is replaced; and through the tunnel lining quality detection mechanical hand, manpower is saved, potential safety hazards are avoided, and the detection efficiency and the detection precision are substantially improved.

Description

technical field [0001] The invention relates to the field of tunnel lining quality testing equipment, in particular to a tunnel lining quality testing manipulator. Background technique [0002] With the continuous development of national transportation, the mileage of railway and highway tunnels is increasing year by year. In order to ensure the safety of tunnel operation, it is often necessary to conduct lining quality inspections for tunnels under construction and in operation, such as detecting the thickness of the tunnel lining and unfilled voids behind the tunnel lining, so that the tunnel construction defects and operational diseases can be treated in a timely manner. [0003] At present, in terms of tunnel lining quality inspection, manual methods are generally used. Manually lift the radar antenna, or inspectors fix the ground radar on a long pole, hold the long pole so that the radar is close to the inspection line, and use the loading Mobile carriers such as machi...

AI Technical Summary

Problems solved by technology

During the detection, in order to maintain the stability of the long rod, it is often necessary for multiple people to support the long rod, which consumes a lot of manpower; at the same time, when the tunnel is detected, the detection distance is long, and multiple operators need to squeeze on the vehicle platform During the inspection, there are great potential safety hazards in the process of moving with the vehicle, and it is labor-intensive to lift the radar or the long pole for a long time. As the physical strength of the personnel declines, the geological radar antenna cannot always be close to the tunnel lining wall, making the radar The antenna and the detection lining wall are separated, or the detection position is shifted, which seriously affects the efficiency, quality and operation safety of the tunnel lining quality inspection
