Automatic detection frame for metal pipeline flaw detector

Abstract

The invention discloses an automatic detection frame for a metal pipeline flaw detector, which comprises an automatic pushing frame, a detection frame and a metal pipe fitting, wherein the automatic pushing frame is integrally arranged on the outer wall of the metal pipe fitting in a sleeving mode. A follow-up pulley and a driving pulley are supported on the inner wall of the automatic pushing frame in a sliding manner; a diameter adjusting device is arranged between the inner wall of the automatic pushing frame and the outer surface of the metal pipe fitting; the detection frame is suspendedon the upper side and the lower side of the metal pipe fitting through a plurality of connecting rods fixed to the side wall of the automatic pushing frame, and angle adjusting mechanisms used for driving the connecting rods to rotate along the center of the automatic pushing frame are arranged between the bottom of the connecting rod and the side wall of the automatic pushing frame. Forward flawdetection of the flaw detector on the surface of the metal pipe fitting can be automatically completed; the process is more accurate than handholding, the deviation of a flaw detection path is reduced, the arranged angle adjusting mechanism ensures that the detection frame can carry out all-around coverage flaw detection on the surface of the metal pipe fitting, the working intensity of an operator in flaw detection work is reduced, and the flaw detection efficiency is improved.

Description

technical field [0001] The invention relates to a construction engineering quality detection device, in particular to an automatic detection frame for a metal pipeline flaw detector. Background technique [0002] In the quality inspection of construction projects, it is often necessary to perform flaw detection on the installed metal pipelines. Flaw detection mainly detects cracks or defects inside metal materials or components. Commonly used flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, Penetrant flaw detection, eddy current flaw detection, gamma ray flaw detection and other methods, according to these aspects, there are many mature flaw detectors on the market, such as metal ultrasonic flaw detectors that are more used in metal detection. [0003] At present, the flaw detectors for pipelines on the market are generally used for hand-held inspections. Engineering quality inspection personnel often need to ...

Problems solved by technology

[0003] At present, the flaw detectors for pipelines on the market are generally used for hand-held inspections. Engineering quality inspection personnel often need to detect and inspect one by one according to the installation direction of the pipelines. Construction installation pipelines are generally long, and many installation locations are not suitable for direct detection by personnel. It is very labor-intensive and time-consuming to carry out all-round detection. Therefore, for this kind of problem, we need a rotating detection frame for existing flaw detectors that can detect without hand-holding.
