Steel pipe nondestructive testing fixing device

Abstract

The invention relates to the field of steel pipe nondestructive testing devices, in particular to a steel pipe nondestructive testing fixing device, which comprises a box body, a supporting structure,a clamping structure, a folding structure, a positioning structure, a limiting structure and a fixing structure. The supporting structure is mounted at the bottom end of the box body to achieve the effect of supporting the box body when the box body is used for nondestructive testing; the box body can be better attached to the surface of the steel pipe, so that movement of the box body is facilitated, and the detection precision is improved; the clamping structure is mounted at the bottom end of the box body in a matched manner, so that the detection head can be conveniently mounted and replaced; by means of folding structure, the assembly for placing the detector can be folded and stored, so that the device is convenient to use; the folding structure is simple in structure and convenientto use, can play a supporting role in use, can be prevented from automatically falling back after being lifted by being matched with the arrangement of the positioning structure, thus ensuring the stability of placing the detector. By means of the limiting structure, the arrangement assembly for placing the detector can be conveniently supported, retracted and stored.

Description

technical field [0001] The invention relates to the field of nondestructive testing devices for steel pipes, in particular to a fixing device for nondestructive testing of steel pipes. Background technique [0002] A steel pipe is a steel material with a hollow section whose length is much greater than its diameter or circumference. According to the cross-sectional shape, it can be divided into circular, square, rectangular and special-shaped steel pipes; according to the material, it can be divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes; Steel pipes for thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc.; according to the production process, they are divided into seamless steel pipes and welded steel pipes, among which seamless steel pipes are divided into hot-rolled and cold-rolled (drawn) Two kinds, welded steel pipe is divided int...

Problems solved by technology

[0003] Some steel pipes used for transporting gas and fluid outdoors, in order to ensure the quality of steel pipes, generally carry out nondestructive testing on steel pipes on a regular basis. At present, when performing nondestructive testing on outdoor steel pipes, the inspectors always hold the detection head. Hold the detector with one hand. When using it, the inspector needs to bring the detection head close to the surface of the steel pipe for back-and-forth detection. It is time-consuming and labor-intensive due to the need for two-handed operation during use, and it is easy to cause uneven detection of the detection head due to manual holding of the detection head.
