Problems solved by technology
At present, for the ultrasonic flaw detection of large-diameter steel pipes, it is usually necessary to hoist the steel pipes into the water tank, drive the steel pipes to rotate in the water tank by the driving device, and then use the ultrasonic probe to detect the flaws. Such flaw detection operations need to be carried out one by one. Hoisting, testing, the hoisting preparation of the whole testing process and lifting the steel pipe after testing takes a long time, which reduces the testing efficiency, and at the same time, the labor intensity of the workers is high

The invention relates to a gantry type steel tube ultrasonic flaw detector, which is characterized by comprising a control system, a gantry frame, a flaw detection trolley, a rotation roller bed device, a feeding device and an unloading device. The rotation roller bed device is used for driving to-be-tested steel pipes to rotate. The feeding device comprises a feeding rack and a single turn-over device, which sends the to-be-tested steel pipes into a knick-off device one by one. The unloading device includes an unloading rack and the knick-off device. The unloading rack is equipped with an inclined rack piece. The knick-off device sends the to-be-tested steel pipes into the rotation roller bed device to undergo rotation detection, and guides the tested steel pipes into the unloading rack. The automatic feeding device and unloading device disposed in the invention act cooperatively with other components to realize automatic ultrasonic flaw detection testing, the hoisting preparation time during testing and the time for hanging the steel pipes after testing are shortened, the detection efficiency is improved, and the labor intensity of workers is alleviated.
Description
technical field [0001] The invention relates to a device for detecting manufacturing defects of steel pipes by using ultrasonic waves, in particular to a gantry type ultrasonic flaw detector for steel pipes, which is used in steel pipe factories to detect the quality of large-diameter steel pipes. Background technique [0002] In the manufacturing process of steel pipes, whether it is seamless steel pipes or welded pipes, due to problems such as slag inclusions in raw materials or loose materials, defects such as cracks and trachoma will occur after the steel pipes are formed. In order to ensure the quality of steel pipe products and reduce the safety in use If there are hidden dangers, it is necessary to use ultrasonic flaw detection equipment to detect steel pipes. At present, for the ultrasonic flaw detection of large-diameter steel pipes, it is usually necessary to hoist the steel pipes into the water tank, drive the steel pipes to rotate in the water tank by the driving...
