Electromagnetic ultrasonic non-contact automatic detector for welding seams of bottom plates of storage tanks

Abstract

The invention relates to an electromagnetic ultrasonic non-contact automatic detector for welding seams of bottom plates of storage tanks. The detector comprises a body, a non-destructive detecting mechanism, a cleaning mechanism, a positioning structure, a control mechanism, a visual monitoring structure and a data processor, wherein driving wheels are arranged at two sides of the body; a pan/tilt camera and a laser radar of the positioning mechanism are arranged at the front end of the top of the body; a camera of the visual monitoring structure is arranged at the bottom of the body; doubleguide rails are also arranged at the bottom of the body; an electromagnetic ultrasonic probe of the non-destructive detecting mechanism is arranged at the lower end of a probe landing gear; the probelanding gear is arranged on a vertical lifting mechanism; the vertical lifting mechanism is fixed on a first right-angle sliding table; the first right-angle sliding table is slidably connected with the double guide rails; a cleaning fan of the cleaning mechanism is arranged through a second right-angle sliding table; the second right-angle sliding table is slidably connected with the double guiderails; and a cleaning brush and the electromagnetic ultrasonic probe are arranged front and back along the double guide rails. By means of the detector disclosed by the invention, after being cleanedby the cleaning brush, a welding seam can be detected by the electromagnetic ultrasonic probe; and the non-contact detection can be realized.

Description

technical field [0001] The invention relates to a device for detecting the weld seam of the bottom plate of a storage tank, in particular to an electromagnetic ultrasonic non-contact automatic detector for the weld seam of the bottom plate of a storage tank. Background technique [0002] The bottom plate of the storage tank is in a complex stress and medium environment, and it is the location where the leakage accidents of the storage tank frequently occur, and the bottom plate weld is one of the high-risk areas. Compared with the entire storage tank bottom plate, the bottom plate weld is the most in need of inspection. At present, manual inspection methods are mainly used for tank bottom plate welds, such as magnetic particle, infiltration, and manual ultrasonic inspection. When the vacuum detection method is adopted, the manual vacuum leak detector is used to automatically apply soapy water to the weld, and the inspector can slowly advance along the weld to detect the weld...
