Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultrasonic flaw detection water tanks, in particular to an ultrasonic flaw detection water tank with a gear train adjustment mechanism. Background Art
[0002] Ultrasonic flaw detection is a non-destructive testing method that uses the difference in acoustic properties of materials and their defects to reflect the ultrasonic propagation waveform and the energy change of penetration time to detect internal defects in materials.
[0003] Ultrasonic water immersion flaw detection is a further development based on the principle of ultrasonic flaw detection. During ultrasonic water immersion flaw detection, the bar to be tested is placed in a water tank. There is a water layer of a certain thickness between the bar and the probe. The ultrasonic wave is emitted through the water layer to generate multiple water interface reflection waves. The bar will also generate reflection waves during the flaw detection process. Since the reflection and propagation speeds of ultrasonic waves in water and in the bar are different, the defect wave can be generated and collected by adjusting the probe and the thickness of the water layer to obtain the specific location, shape and size of the defect, thereby overcoming the blind spots of traditional ultrasonic flaw detection and achieving flaw detection without blind spots.
[0004] At present, when testing rods with water-immersion ultrasonic flaw detection water tanks, both ends of the tested rods need to be fixed with clamps, and usually only a small range of length adjustment is available. When the length span of the tested rods is large, multiple ultrasonic flaw detection water tanks for corresponding lengths need to be used, which increases the testing cost and is inconvenient to operate.

The fourth limit block bracket 714 is fixedly mounted on the carriage 5, located between the moving wheel group 6 and the second limit block bracket 712. The carriage chain 9 is fixed on the carriage 5. Preferably, the carriage 5 is provided with two fixed blocks for mounting the two ends of the carriage chain 9, and the positions of the two fixed blocks are parallel to the slide rail 3 along the length direction. The steering sprocket 8 is fixedly mounted on the bottom of the water tank 1 on one side of the slide rail 3, close to the fixed wheel set 2. The chain drive box 10 is fixedly mounted on the bottom of the water tank 1, close to the side of the water tank 1 of the second limit block bracket 712. A chain drive device 11 is provided inside the chain drive box 10. Preferably, the chain drive box 10 is parallel to the steering sprocket 8 and the fixed block. The drag plate chain 9 is fixed to the drag plate 5 through the steering sprocket 8 and the chain drive device 11. Preferably, the drag plate chain 9 adopts a double chain. The motor 12 with an encoder is fixed on the upper part of the chain drive box 10 and connected to the chain drive device 11. The motor 12 with an encoder is installed at a position higher than the water tank to protect the motor 12.
[0028] The first limit block bracket 711, the second limit block bracket 712, the third limit block bracket 713 and the fourth limit block bracket 714 have the same structure, and each limit block bracket 71 includes two columns 715 with grooves 716. Preferably, the grooves 716 are installed relative to each other to form a space for fixing the limit block 72; the first limit block 721 and the second limit block 722 have the same structure, and each limit block 72 has a protrusion 723 corresponding to the groove 716 to facilitate the insertion and removal of the limit block 72 into and out of the limit block bracket 71.
[0029] The chain transmission device 11 can be composed of a driving sprocket, a chain, a passive sprocket and a driven sprocket. The passive sprocket is mechanically connected to the driven sprocket. The motor 12 is connected to the driving sprocket. The drag plate chain 9 is fixed on the drag plate 5 through the steering sprocket 8 and the driven sprocket. The drag plate chain 9 is parallel to the slide rail 3 along the length direction.
[0030] Working principle:
[0031] When it is necessary to detect the bar material, the program setting is required. The data is set according to the length of the bar material to be detected. The motor 12 runs, driving the chain transmission device 11 in the chain transmission box 10 to run. The chain transmission device 11 drives the drag chain 9 to rotate, and the steering sprocket 8 rotates accordingly. At the same time, the drag chain 9 pulls the drag plate 5, and the slider 4 under the drag plate 5 moves on the slide rail 3.
[0032] Through the feedback value provided by the encoder carried by the motor 12, the program determines that after the moving wheel group 6 reaches the specified position, the motor 12 is locked, the chain transmission device 11 stops running, the drag plate chain 9 and the steering sprocket 8 stop rotating, the drag plate 5 stops moving, and the moving wheel group 6 stops moving. In this way, the position switching of the moving wheel group 6 of the support for bars above 800 mm can be automatically achieved without human intervention.
[0033] The bar material to be tested is directly placed on the fixed wheel set 2 and the movable wheel set 6, and does not need to be fixed with a clamp, which is convenient for operation. According to the length of the bar material to be tested, the first limit block 721 is inserted into the first limit block bracket 711 or the third limit block bracket 713, and the second limit block 722 is inserted into the second limit block bracket 712 or the fourth limit block bracket 714, and then the test is started.
[0034] During the detection process, the rotation of the fixed wheel group 2 drives the rod to rotate, and the rotation of the rod drives the rotation of the movable wheel group 6; during the rotation of the rod, axial displacement of the rod may occur, and the first limit block 721 and the second limit block 722 can support the rod and limit the axial displacement of the rod between the first limit block 721 and the second limit block 722.
[0035] When the length of the rod material to be detected is the maximum length that the water tank can detect, the first limit block 721 is inserted into the first limit block bracket 711 , and the second limit block 722 is inserted into the second limit block bracket 712 .
