[0020] During operation, the utility model can perform straightening operations on multiple directions of steel pipes with different diameters at the same time under the cooperation of the first lifting component and the position adjustment component, which can ultimately improve the straightening effect of the steel pipes.

[0021] Furthermore, the second lifting assembly includes a second electric telescopic rod 16 and a connecting frame 6. The second electric telescopic rod 16 is fixedly connected to the inside of the two first fixed frames 2. The connecting frame 6 is slidably connected to the inside of the two first fixed frames 2.

[0022] When working, the second electric telescopic rod 16 can drive the connecting frame 6 to perform lifting operations, and then drive the upper pressing roller 19 to perform lifting operations with the cooperation of the sliding seat 5. At this time, it plays a role in adjusting the height of the upper pressing roller 19, so that the upper pressing roller 19 cooperates with the lower pressing roller 20 to smoothly clamp and convey steel pipes of different diameters.

[0023] Furthermore, the first lifting assembly includes a second support frame 21, a first support frame 7, a first electric telescopic rod 8 and a second fixed frame 9. The ends of the two first fixed frames 2 that are close to each other are fixedly connected to the second support frame 21.

The interiors of the two first support frames 7 are fixedly connected to the first electric telescopic rod 8.

The interiors of the two second fixed frames 9 are rotatably connected to two first straightening rollers 10, and the multiple first straightening rollers 10 are respectively located directly above the corresponding support rollers 14.

[0024] During operation, the first electric telescopic rod 8 operates, which can drive the second fixed frame 9 to perform lifting operations, and then drive the first straightening roller 10 to perform lifting operations. At this time, the distance between the first straightening roller 10 and the supporting roller 14 gradually changes until the distance between the two matches the diameter of the steel pipe.

[0027] Further, the position adjustment component includes a second motor 11, a bidirectional threaded rod 23, a transmission wheel 17, a belt 18 and a moving seat 13. The two vertical plates 15 are internally rotatably connected with the bidirectional threaded rod 23. There are three bidirectional threaded rods 23, which are respectively located between the leftmost first fixed frame 2 and the support roller 14, between the rightmost first fixed frame 2 and the support roller 14, and between the two support rollers 14 in the middle. The circumferential surfaces of the three bidirectional threaded rods 23 are all threadedly connected to two moving seats 13. The two moving seats 13 are symmetrically distributed front and back. The upper ends of the two vertical plates 15 are rotatably connected with the second straightening roller 12, a second guide rod is fixedly connected between the two vertical plates 15, the second guide rod passes through the moving seat 13, and the moving seat 13 is slidably connected to the second guide rod, three bidirectional threaded rods 23 pass through the vertical plates 15 backwards, the rear ends of the three bidirectional threaded rods 23 are fixedly connected with the transmission wheels 17, and two adjacent transmission wheels 17 are connected by belts 18, and the front end of the front vertical plate 15 is fixedly connected with the second motor 11, and the output shaft end of the second motor 11 is fixedly connected to the bidirectional threaded rod 23 in the middle position.

[0028] During operation, the second motor 11 can drive the bidirectional threaded rod 23 in the middle position to rotate, and then drive the transmission wheel 17 in the middle position to rotate. At this time, under the action of the belt 18, each transmission wheel 17 can rotate at the same time, and then each bidirectional threaded rod 23 can rotate at the same time. The rotation of the bidirectional threaded rod 23 under the action of the second guide rod makes the two moving seats 13 drive the two second straightening rollers 12 to move closer to or away from each other more stably until the distance between the two straightening rollers matches the diameter of the steel pipe. Then, the two straightening rollers can be used to straighten the front and rear ends of the two steel pipes.

[0029] Furthermore, a third motor 22 is fixedly connected to the front end of the front vertical plate 15 , and an output shaft end of the third motor 22 is fixedly connected to one of the support rollers 14 at the middle position.

[0030] When working, the third motor 22 operates to drive the corresponding support roller 14 to rotate. As the support roller 14 rotates, it is convenient to drive steel pipes of different specifications to gradually move, thereby facilitating straightening operations at different positions of the steel pipes.

[0031] Working principle:

[0032] When in use, first adjust the height of the first straightening roller 10 and the upper pressure roller 19, as well as the distance between the two second straightening rollers 12 according to the diameter of the steel pipe. At this time, control the operation of the second lifting component to drive the upper pressure roller 19 to perform lifting operations until the distance between the upper pressure roller 19 and the lower pressure roller 20 matches the diameter of the steel pipe. Then control the operation of the first lifting component. Under the action of the first lifting component, drive the first straightening roller 10 to perform lifting operations. At this time, the distance between the first straightening roller 10 and the support roller 14 gradually changes until the distance between the two matches the diameter of the steel pipe. Then control the operation of the position adjustment component to adjust the distance between the two second straightening rollers 12 until the distance between the two second straightening rollers 12 matches the diameter of the steel pipe. Then the steel pipe can be placed, and the first straightening roller 10 cooperates with the support roller 14 to simultaneously straighten the upper and lower ends of the steel pipe. The two second straightening rollers 12 cooperate with each other to straighten the front and rear ends of the steel pipe. In this way, straightening operations can be performed simultaneously in multiple directions of steel pipes of different diameters, and the straightening effect of the steel pipe can be improved.
