Problems solved by technology

The present invention detects the inner wall of the tunnel lining in order to solve the lack of a special device in the prior art. The detection of the tunnel state is generally carried out by manpower lifting radar, resulting in high physical labor intensity and low detection efficiency; due to the detection radar and the tunnel lining inner wall The distance between them will change continuously due to the unevenness of the inner wall surface and the concave-convex arc surface. The artificial lifting force is unstable, the stroke is short, and the detection signal is not stable due to untimely reflection, which affects the detection effect.

Abstract

The invention discloses a radar test rod for tunnel state detection, and belongs to the technical field of tunnel state detection. The test rod comprises a first sleeve, n levels of sleeves sleeved bythe first sleeve, a telescopic oil cylinder assembled in the sidewall of the n levels of sleeves and driving the n levels of sleeves to telescope, swing oil cylinders arranged in left and right sidewalls of the first sleeve symmetrically, an angle scale, a hydraulic control integrated block, a holder and a detection radar. The working efficiency and detection signal stability of tunnel state detection are improved, control is convenient, lifting is smooth, the reflection speed is high, the telescopic oil cylinder and swinging oil cylinders are controlled by hydraulic pressure, and motion is timely and rapid. The swing oil cylinders moves under the hydraulic effect and drives the test rod to swing left and right, the detection angle of the test rod can be adjusted timely, and the stabilityand accuracy of the detection signals are ensured.

Description

technical field [0001] The invention relates to the technical field of tunnel state detection, in particular to a radar detection rod for tunnel state detection. Background technique [0002] At present, in the process of detecting railway tunnel quality defects, there is no special device in China to detect the inner wall of the tunnel lining. The detection of tunnel status is generally carried out by means of human-lifted radar, which results in high physical labor intensity and low detection efficiency. The maximum detection speed is only It can reach 1km / h. In addition, because the distance between the detection radar and the inner wall of the tunnel lining will change continuously due to the unevenness of the inner wall and the concave-convex arc surface, the artificial lifting force is unstable, the stroke is short, and the detection signal is not stable due to untimely reflection, which affects the detection effect. Contents of the invention [0003] The object of ...
