Problems solved by technology

[0003] When the existing TOFD detection device is in use, workers need to climb on the equipment to be tested and carry the detection device to simultaneously detect and process the welds on the equipment to be tested. However, when this method is used, the detection is difficult and requires more A lot of manpower and time, low work efficiency, workers are prone to the risk of falling, and at the same time, when manually carrying the detection device to climb, the stability of the detection device is poor, and the detection accuracy of the detection equipment is low

Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0043] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent exclusive embodiments.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in ...

Abstract

The invention relates to the technical field of mechanical equipment, and particularly relates to a large component visual butt welding joint TOFD detection device and a detection method. A first power assembly can drive an ultrasonic transceiver to move towards a detection surface. A crawler belt is driven by a second power assembly arranged on a mounting base to rotate and drives the mounting base to move in the detection direction, an adsorption assembly comprises suction cups evenly distributed in the circumferential direction of the crawler belt, the suction cups provide a suction force through an air suction assembly so that the crawler belt can be adsorbed to equipment to be detected, and a oil coating mechanism carries out oil brushing treatment on the detection surface. The detection device can effectively simplify the detection mode, save the time and physical strength during manual detection, improve the working efficiency, avoid falling and damage during manual detection, improve the operation stability of the detection device, and effectively improve the detection precision by automatically detecting a welding seam on the external to-be-detected equipment. And practicability and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a TOFD detection device and detection method for visual butt welded joints of large components. Background technique [0002] At present, the TOFD detection device refers to the ultrasonic detection equipment that uses the diffraction signal of the defect end point to detect and measure the defect size. It mainly uses ultrasonic waves to transmit in the welded joint, and welding defects such as pores and cracks in the weld interfere with the waveform of the ultrasonic waves. Influence, through the analysis of the ultrasonic waves after interference, so as to achieve the purpose of detection. [0003] When the existing TOFD detection device is in use, workers need to climb on the equipment to be tested and carry the detection device to simultaneously detect and process the welds on the equipment to be tested. However, when this method is used, the detection is difficu...
