Abstract

The invention discloses a water-driving TOFD (time of flight diffraction) scanning device. The device comprises a cross beam, TOFD scanning mechanisms, scanning water supply nozzles and a water driving mechanism, wherein T-shaped sliding chutes which are through in the length direction of the cross beam are formed in upper, lower, front and back side surfaces of the cross beams; the TOFD scanningmechanisms are mounted on the T-shaped sliding chute in the front side of the cross beam through sliders and can slide left and right in the length direction of the cross beam and perform locking; thewater driving mechanism is mounted on the cross beam and can drive the cross beam to enable the TOFD scanning mechanisms to advance; the scanning water supply nozzles are fixed on the sliders, outlets of the nozzles are aligned to working positions of scanning probes, and the scanning water supply nozzles are communicated with a water outlet of the water driving mechanism through a hose. The water-driving TOFD scanning device is simple in structure and provides power for scanning advance in a water driving mode, meanwhile, water for driving is used as a coupling agent in a detection process,automatic scanning is realized, and the device is small, exquisite and flexible.

Description

technical field [0001] The invention relates to a water-driven TOFD scanning device. Background technique [0002] At present, TOFD detection mainly includes manual and electric detection. Manual detection mainly uses the hand to push the scanning device along the weld seam for detection, which requires high uniformity in the speed of the human push. At the same time, a tester is also required to cooperate with water spray coupling. Electric detection mainly uses a DC motor or a stepping motor as power. This type of scanning device needs to be equipped with a power supply to supply power to the motor, and an inspector is required to cooperate with the water spray coupling. The system is more complicated. Contents of the invention [0003] The technical problem solved by the present invention is: the present invention provides a water-driven TOFD scanning device, which can realize the use of water-driven impellers to drive the scanning device, and at the same time serve as...
