Large-pipe-diameter seamless steel pipe internal flaw detection equipment

Abstract

The invention discloses large-pipe-diameter seamless steel pipe internal flaw detection equipment, which comprises a fixing box, wherein a fixing cavity is formed in the fixing box, and a detection and repair mechanism is arranged in the fixing cavity, and comprises a driving motor fixedly connected to the upper side of the fixing cavity. According to the invention, by utilizing a reciprocating elliptical chute structure and a buffer torsion spring, an inclined guide surface is used for guiding, a repairing box is tightly attached to the inner wall of a large-diameter steel pipe, and a reciprocating lead screw and a telescopic plate are used for driving the repairing box to slowly slide forwards so as to detect the inner wall of the large-diameter steel pipe; when a detection head finds that a gap and a recess are formed in the inner wall of the steel pipe, the equipment can automatically repair the sunken part, and can automatically supplement a repair liquid after repair, so that recycle next time is convenient, and time and labor are saved; and the equipment has a positioning function, can fix the fixing box at one end of the steel pipe, and ensures that the repair mechanism can vertically enter the steel pipe, so that the detection and repair efficiency of the interior of the steel pipe is ensured.

Description

technical field [0001] The invention relates to the technical field of steel pipe detection, in particular to a large-diameter seamless steel pipe internal flaw detection equipment. Background technique [0002] Seamless steel pipe is a steel pipe that is perforated by a whole round steel and has no welds on the surface. Before using the seamless steel pipe, it is necessary to check the internal gap of the steel pipe to check whether it is seamless. If the steel pipe with the gap is used as a seamless steel pipe, it will cause toxic gas leakage and other phenomena, and the consequences will be disastrous. The most common detection method is manual detection. This detection method is not only time-consuming and laborious, but also extremely difficult to detect the inside of the steel pipe. It will waste a lot of time to repair after the gap is detected. Contents of the invention [0003] The object of the present invention is to provide a large-diameter seamless steel pipe...
