Two-track portable pipeline digital weld inspection device

Abstract

A dual-track portable pipeline digital weld inspection device. The main purpose is to solve the problems that the existing pipeline welding seam detection device is inconvenient to disassemble and assemble, the walking foot and the track are easily damaged due to the heavy equipment, and the degree of protection of the equipment is low. It is characterized in that: the device is composed of an imaging plate clamping unit, a driving unit, an X-ray clamping unit, a left connecting rod, a right connecting rod, a main rail and a sub-rail connected; the imaging plate clamping unit includes an imaging plate frame, a Walking wheel and imaging plate protection frame; drive unit includes reducer, motor, rear plate, front plate, handle, sprocket and walking wheel; reducer is fixed on the rear plate; X-ray clamping unit includes X-ray fixing frame, X-ray The frame and the walking wheels; the walking wheels are respectively fixed on the X-ray frame by two bolts; the main track is composed of the main track and the chain; the auxiliary track is fixed by the protrusions and pipes at the bottom, and the two are concentric; the drive unit is located on the imaging board Between the holding unit and the X-ray holding unit.

Description

technical field [0001] The invention relates to a pipeline weld detection device applied in the field of oil and gas transportation. Background technique [0002] Once an oil transportation pipeline accident occurs, it will not only cause huge economic losses, but also cause immeasurable harm to society and the environment. Its restoration is not only difficult, but also expensive. Because the damage of circular storage tanks and pipelines is mainly concentrated on the damage of the weld, but because the pipeline weld detection has been carried out with a more traditional manual detection method, there is no proposal for a pipeline weld detection that can realize the detection of mechanical automation The rapid and effective detection method and supporting devices, and the existing detection device has a complex structure, which is not easy to assemble and disassemble, resulting in low detection efficiency. At the same time, the X-rays used in the inspection will cause cer...
