The invention discloses a tunnel lining detection support with a height and an angle capable of being automatically adjusted, which comprises a
radar bracket, wherein the axle center position of the lower side of the
radar bracket is provided with a main support rod, one end of the main support rod is connected with the
radar bracket through a
universal joint, the other end of the main support rod is arranged on a fixed base through a
universal joint, the downside of the main support rod is fixed on the fixed base through at least three air struts uniformly distributed around the main support rod, the two ends of the air struts are respectively connected with the main support rod and the fixed base through universal joints, the upside of the main support rod is connected with the radar bracket through at least three spring support rods uniformly distributed around the main support rod, and the two ends of the spring support rods are respectively connected with the bottom of the radar bracket and the main support rod through universal joints. The tunnel lining detection support disclosed by the invention is simple in structure, easy to disassemble, and convenient to carry; the tunnel lining detection support can guarantee that a preset distance is always kept between a radar antenna and a tunnel lining surface in the
horizontal and vertical directions; and due to the automatic height and angle adjustment function, the influence of road unevenness on detecting results is reduced, the erection of temporary operating supports and the manual lifting are avoided, the working intensity of detection is lowered, and the detection speed is improved.
