A non-destructive testing device for the inner wall of a pipe

Abstract

The invention discloses a nondestructive testing device for the inner wall of a tube. The structure of the nondestructive testing device comprises a pushing-pull support, a tablet computer, a tube detection device, a waterproof wire, a lateral fixed support, a take-up frame, a moving rack, idler wheels and a hinge pin. According to the nondestructive testing device for the inner wall of a tube, rolling devices are uniformly arranged on the surface of the machine body in equal distances, and balls are arranged on the rolling devices to realize random movement of the tube detection device on theinner wall of the tube, increase the flexibility of the machine body and improve the detection stability and accuracy of a rotatable camera at the front end of the machine body for the inner wall ofthe tube.

Description

technical field [0001] The invention relates to a non-destructive testing device for the inner wall of a pipe, which belongs to the field of detection devices for the inner wall of a pipe. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipe fittings use different pipe materials, and the quality of the pipe directly determines the quality of the pipe fittings. This kind of pipe is often used in construction projects, power plants, chemical plants, etc. At present, the interior of metal tubular parts is prone to corrosion, and the seams of some welded tubular materials still need to be inspected [0003] Due to the limitations of the radius, deformation and internal conditions of the pipe material in the prior art, it is extremely inconvenient and inaccurate for personnel to detect the pipe material, which makes the work efficiency low and consumes a lot of human resources and funds. The inner wall generally uses various sensor probe...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a non-destructive testing device for the inner wall of the pipe, so as to solve the problem that the non-destructive testing device for the inner wall of the pipe is extremely inconvenient for personnel to detect the pipe due to the limitation of the radius, deformation and internal conditions of the pipe. It is also inaccurate, which makes the work efficiency low and consumes a lot of human resources and funds. Now, various sensor probes are generally used on the inner wall of the pipe to detect whether the inner wall of the pipe is cracked. It is difficult for the probe to move on the inner wall of the pipe, which makes the detection difficult. question
