Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] Refer to Figures 1-4, A full-automatic ultrasonic testing reference block for thick-walled circumferential welds, including an adjusting block 1. The adjusting block 1 is sleeved with a basic block 2. One side of the basic block 2 is provided with a knob 3. The knob 3 is provided with a rotating rod 4 on the side close to the basic block 2. The rotating rod 4 penetrates through one side of the basic block 2. The outer wall of the rotating rod 4 is fixedly connected with a worm 5. The top of the worm 5 is provided with a worm gear 6. The worm 5 and the worm gear 6 are adapted to each other. The worm gear 6 is fixedly connected with a lead screw 7 on the side close to the adjusting block 1. Both inner walls of the basic block 2 are fixedly connected with first fixing plates 8. The first fixing plates 8 are fixedly connected with guide rods 9 on the side close to the adjusting block 1. The adjusting block 1 is provided with a thread groove 10 adapted to the lead screw 7. The lead screw 7 is arranged in the thread groove 10. The adjusting block 1 is provided with a guide groove 11 adapted to the guide rod 9. The guide rod 9 is arranged in the guide groove 11. By setting the lead screw and the thread groove, by rotating the knob, the worm can drive the worm gear to rotate, the worm gear can drive the lead screw to rotate, and the lead screw can drive the adjusting block to move, so that the length of the device can be adjusted. It effectively solves the problems proposed in the background technology that the adjusted length is fixed, resulting in low adjustment accuracy, and the method of adjusting the length is more cumbersome, requiring multiple times of screwing and removing the fixing bolts and then reinstalling them, with low adjustment efficiency. Furthermore, it realizes the technical effects of simple operation, capable of improving the efficiency of adjusting the length and the accuracy of adjusting the length.

[0022] In this embodiment, the basic block 2 is fixedly connected with a mounting plate 12 on the side far from the adjusting block 1.

[0023] In this embodiment, the adjusting block 1 is fixedly connected with a large sector 13 and a small sector 14 on the side far from the basic block 2.

[0024] In this embodiment, a connecting rod 15 is arranged in the basic block 2. The connecting rod 15 is fixedly connected with the worm gear 6. The outer wall of the connecting rod 15 at the end far from the worm gear 6 is fixedly connected with a first ring 16. The first ring 16 is sleeved with a first sleeve plate 17. The outer wall of the first sleeve plate 17 is fixedly connected with two second fixing plates 21. The second fixing plates 21 are fixedly connected with the basic block 2.

[0025] In this embodiment, the inner wall of the basic block 2 is fixedly connected with a second sleeve plate 19. The inner wall of the second sleeve plate 19 is rotatably connected with a second ring 18. The inner wall of the second ring 18 is fixedly connected with the rotating rod 4.

[0026] In this embodiment, the inner wall of the basic block 2 is fixedly connected with two partition plates 20. The partition plate 20 close to the adjusting block 1 is sleeved on the lead screw 7 and the guide rod 9.

[0027] Working principle: When using this device, the sound velocity calibration and the measurement of the probe front can be carried out from the bottom of the test block through the large sector 13 and the small sector 14. When it is necessary to adjust the length of this device, the knob 3 can be rotated. The knob 3 will drive the rotating rod 4 to rotate, the rotating rod 4 will drive the worm 5 to rotate, the worm 5 will drive the worm gear 6 to rotate, the worm gear 6 will drive the lead screw 7 to rotate, and the lead screw 7 will drive the adjusting block 1 to move. When the adjusting block 1 moves, it will move along the guide rod 9. Due to the restriction of the guide rod 9, the adjusting block 1 will not shift when moving, so that the adjusting block 1 moves away from the basic block 2, and the length of this device can be increased. Reversing the knob 3 can reduce the length of this device, so that this device can be adjusted according to the detection situation, making the process of thick-walled girth weld detection more accurate. When the worm gear 6 rotates, it will also drive the connecting rod 15 to rotate, and the connecting rod 15 will drive the first ring 16 to rotate within the first sleeve 17. Through the mutual cooperation of the connecting rod 15 and the first ring 16, the worm gear 6 will not shift when rotating. When the rotating rod 4 rotates, it will also drive the second ring 18 to rotate, and the second ring 18 will rotate within the second sleeve 19. Through the mutual cooperation of the second ring 18 and the second sleeve 19, the worm 5 will not shift when rotating.

[0028] For the sake of convenience of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation depicted in the figure of the device. For example, if the device in the drawing is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.
