Description

Technical Field

[0001] The utility model relates to the technical field of flaw detection equipment, in particular to a flaw detection equipment for tank body welding. Background Art

[0002] The production of the tank body is usually not integrally formed, but is welded by the cylindrical section of the tank body and the hemispherical sections at both ends. After preliminary spot welding of the joints, the joints are successively subjected to full-seal welding by an automatic welding equipment and then ground and beautified to form a complete tank body structure. When accepting and detecting the tank body, flaw detection equipment is often used to detect the weld quality of multiple joints of the tank body to avoid hidden injuries such as tiny cavities and gaps in the welds, which may affect the normal application of the tank body. However, the detection probe is usually held by the detector. During multiple detections, it is easy to cause fatigue of the detector and inaccurate detection. The Chinese Patent Network discloses a tank body weld flaw detection device with the label "CN214252227U". By setting a lead screw module, a moving table is slidably assembled on one side of the lead screw module away from the handrail. A linear electric actuator is horizontally and fixedly installed on one side of the moving table away from the handrail. The linear electric actuator is provided with a telescopic rod. A buffer device is arranged at one end of the telescopic rod away from the battery box. A detection probe is fixedly installed at one end of the buffer device away from the battery box to adjust and position the position of the detection probe. However, during use, the position still needs to be manually adjusted for detection, wasting physical strength and time. Content of the Utility Model
