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

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a traveling device for non-destructive testing of bearing steel pipes, including a bottom plate 1 and a bearing steel pipe body 2. A first vertical plate 3 is fixedly installed at the rear end of the middle above the bottom plate 1. A first horizontal plate 4 is fixedly installed above the front end of the first vertical plate 3. An electric cylinder 1 is fixedly installed above the first horizontal plate 4. A pressing block 6 is arranged below the first horizontal plate 4. The push rod end of the electric cylinder 1 penetrates through the first horizontal plate 4 and is fixedly connected to the pressing block 6. A driving wheel frame 9 is arranged below the pressing block 6. A driving wheel 10 is rotatably installed inside the driving wheel frame 9. A first motor 11 is fixedly installed at the front end of the driving wheel frame 9. The output end of the first motor 11 is fixedly connected to the driving wheel 10.

[0025] During use, during the non-destructive testing of the bearing steel pipe, the driving wheel frame 9 is driven to move downward by the electric cylinder 1 so that the driving wheel 10 contacts the bearing steel pipe body 2. Then, by starting the first motor 11, the driving wheel 10 is driven to rotate, which can drive the movement of the bearing steel pipe body 2, realizing the automatic advancement of the bearing steel pipe during the non-destructive testing process. There is no need for manual operation, which increases the convenience of the advancement of the bearing steel pipe. And by automatically driving the bearing steel pipe to advance, the bearing steel pipe can travel at a uniform speed, which is beneficial to the non-destructive testing work of the bearing steel pipe and increases the practicality.

[0026] Furthermore, a convex plate 8 is fixedly installed at the front end of the pressing block 6. A first guide rod 7 is fixedly installed above the convex plate 8. The upper end of the first guide rod 7 penetrates through the first horizontal plate 4. Through the arrangement of the first guide rod 7, the lifting movement of the pressing block 6 can be guided, increasing the linear stability of the lifting movement of the pressing block 6.

[0027] Furthermore, second vertical plates 14 are symmetrically and fixedly installed on both sides of the first vertical plate 3 above the bottom plate 1. A second horizontal plate 15 is fixedly installed above the front end of the second vertical plate 14. An electric cylinder 2 is fixedly installed above the second horizontal plate 15. An upper auxiliary box 17 is arranged below the second horizontal plate 15. The push rod end of the electric cylinder 2 penetrates through the second horizontal plate 15 and is fixedly connected to the upper auxiliary box 17. A lower auxiliary box 18 is arranged below the upper auxiliary box 17. The lower auxiliary box 18 is fixedly connected to the bottom plate 1, so that by starting the electric cylinder 2, the upper auxiliary box 17 can be driven to move up and down.

[0028] Further, a second guide rod 19 is fixedly installed at the rear end above the upper auxiliary box 17. The upper end of the second guide rod 19 penetrates through the second cross plate 15. The setting of the second guide rod 19 can guide the lifting movement of the upper auxiliary box 17. Two auxiliary wheel frames 25 are symmetrically arranged on the inner sides of the upper auxiliary box 17 and the lower auxiliary box 18 respectively. An auxiliary wheel 26 is rotatably installed inside the auxiliary wheel frame 25. By arranging two auxiliary wheels 26 below the upper auxiliary box 17 and above the lower auxiliary box 18 respectively, the position of the bearing steel pipe can be restricted, preventing the bearing steel pipe from tilting up.

[0029] Further, the internal and external structures of the upper auxiliary box 17 and the lower auxiliary box 18 are the same. A ball screw 21 is rotatably installed inside the lower auxiliary box 18. The threads at both ends of the outer side of the ball screw 21 are arranged in opposite directions.

A transmission plate 24 is fixedly installed above the sliding block 22. A table plate 23 is fixedly installed below the auxiliary wheel frame 25. The transmission plate 24 is fixedly connected to the table plate 23. By driving the ball screw 21 to rotate, the two auxiliary wheel frames 25 can move synchronously, making the two auxiliary wheels 26 approach or move away from each other, which is beneficial to adjusting the distance between the two auxiliary wheels 26 according to the diameter of different bearing steel pipe bodies 2, facilitating the stable placement of the bearing steel pipe body 2.

[0030] Further, a protective cover 20 is fixedly installed on one side of the lower auxiliary box 18. A second motor 27 is arranged inside the protective cover 20.

A limiting plate 12 is fixedly installed above the driving wheel frame 9. Two compression springs 13 are symmetrically and fixedly installed on both sides above the limiting plate 12 respectively. The upper ends of the compression springs 13 are fixedly connected to the pressing block 6. Due to the elasticity of the compression springs 13, the excessive downward movement distance of the pressing block 6 can be prevented, which is beneficial to the driving wheel 10 stably pressing on the bearing steel pipe body 2, increasing the practicability.

[0032] Working principle: When in use, place the bearing steel pipe body 2 between two auxiliary wheels 26 on the lower auxiliary box 18, and then drive the upper auxiliary box 17 to move downward through the second electric cylinder 16, so that the two auxiliary wheels 26 above press down on the bearing steel pipe, which can limit the position of the bearing steel pipe and prevent the bearing steel pipe from tilting. Then, drive the driving wheel frame 9 to move downward through the first electric cylinder 5 so that the driving wheel 10 contacts the bearing steel pipe body 2, and then start the first motor 11 to drive the driving wheel 10 to rotate, which can drive the movement of the bearing steel pipe body 2, realizing the automatic advancement of the bearing steel pipe during the flaw detection process.
