[0021] Optionally, the connecting rods are arranged in a V-shape.

[0022] By adopting the above technical solution, the connecting rod arranged in a figure-eight shape can push the third plate and the cleaning component to stick tightly to the steel pipe when the elastic element pulls the block closer, thereby achieving the cleaning of residual liquid on the surface of steel pipes of different sizes.

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0030] This application discloses a continuous steel pipe processing apparatus.

[0031] Reference Figure 1 The continuous steel pipe processing device includes: a machine body 1, a second plate 2, a drive assembly 3, and a cleaning unit 4. By mounting the cleaning unit 4 on the drive assembly 3 and driving the cleaning unit 4 to rotate, the residual liquid on the surface of the steel pipe is removed, reducing the impact on subsequent processing.

[0032] like Figure 5 As shown, the machine body 1 is used for continuous processing of steel pipes. Specifically, the machine body 1 includes a rectangular first plate 11, which serves as a base for support and installation; a bending unit 12 is installed on the first plate 11, which bends steel sheets into steel pipes through a series of guide wheels with gradually decreasing spacing, which is a conventional process; a welding unit 13 is installed on the first plate 11, which is used for welding the joints of the steel pipes, which is a conventional process; a first cleaning unit 14 is installed on the first plate 11, which is used for cleaning welding slag, which is a conventional process; and a grinding unit 15 is installed... The first plate 11 is used for grinding steel pipes, which is a conventional process; the second cleaning unit 16 is installed on the first plate 11 and is used for cleaning grinding residues, which is a conventional process; the solution treatment unit 17 is installed on the first plate 11 and is used for heat treatment of steel pipes, which is a conventional process; the third cleaning unit 18 is installed on the first plate 11 and is used for cleaning heat-treated steel pipes; the cutting unit 19 is installed on the first plate 11 and is used for cutting steel pipes, which is a conventional process; the continuous processing of steel pipes can be completed through the above process.

[0033] like Figure 1 As shown, in order to ensure that the cleaned steel pipe does not affect the subsequent processing flow, in a further embodiment, the square second plate 2 is fixedly installed on the first plate 11 and can be set after the cleaning process. The second plate 2 has a circular channel 21 in the center for the steel pipe to pass through, and the diameter of the channel 21 is larger than that of the steel pipe to be processed.

[0034] like Figure 1 As shown, the drive assembly 3 is mounted on the second plate 2, and it is used to drive the cleaning unit 4 to rotate. Specifically, as shown... Figure 2 As shown, the drive assembly 3 includes: a bearing 31, a ring 32, a gear ring 33, a drive component 34, a rotating shaft 35, and a first gear 36.

[0035] like Figure 2As shown, bearing 31 has an inner ring and an outer ring, with the inner ring fixedly installed on one side of the second plate 2; ring 32 is annular and is fixedly installed on the outer ring of bearing 31 to allow free rotation of ring 32; gear ring 33 is annular with teeth facing outward and is fixedly installed on one side of ring 32; drive component 34 is a motor, which is fixedly installed on the other side of the second plate 2; rotating shaft 35 is a circular rod that passes through the second plate 2 and is rotatably connected to the second plate 2, and drive component 34 can drive rotating shaft 35 to rotate, that is, the output end of the motor is coaxially fixedly connected to rotating shaft 35; first gear 36 is fixedly installed on one side of rotating shaft 35 and meshes with gear ring 33.

[0036] like Figure 1 As shown, two cleaning units 4 are arranged around channel 21, specifically, as follows: Figure 3 As shown, the cleaning unit 4 includes a rotating rod 41 and an elastic component 44.

[0037] like Figure 3 As shown, a circular rod-shaped rotating rod 41 is mounted on the drive assembly 3. Specifically, the rotating rod 41 passes through the gear ring 33 and is rotatably connected to the gear ring 33. An elastic component 44 is mounted on the rotating rod 41, and the elastic component 44 can maintain contact with the steel pipe through its own elasticity. When the drive component 34 sequentially drives the rotating shaft 35, the first gear 36, the gear ring 33, the rotating rod 41, and the elastic component 44 to rotate, the elastic component 44 can complete the cleaning of the outer wall of the steel pipe.

[0038] like Figure 3 As shown, to enhance the cleaning effect of the elastic component 44, in a further embodiment, a second gear 42 is fixedly installed on one side of the rotating rod 41, and a gear ring 43 is fixedly installed on one side of the second plate 2. The second gear 42 meshes with the gear ring 43. When the rotating rod 41 rotates around the channel 21, the second gear 42 simultaneously drives the rotating rod 41 to rotate by meshing with the gear ring 43. This allows the elastic component 44 to rotate and change its contact position with the steel pipe while cleaning around the steel pipe, thus avoiding prolonged contact with the steel pipe at the same position, which would reduce the cleaning effect.

[0039] like Figure 3 As shown, in order to increase the frequency of contact surface changes, in a further embodiment, the toothed ring 43 is an internal toothed ring, so that the rotation direction of the elastic component 44 is opposite to the rotation direction, the frequency of contact surface changes increases, and the cleaning effect is improved.

[0040] like Figure 4 As shown, in order to make the elastic component 44 applicable to steel pipes of different sizes and improve the applicability of the device, in a further embodiment, the elastic component 44 includes: a fastener 441 and an elastic structure.

[0041] like Figure 4As shown, the fixing member 441 has a hexagonal side and is fixedly installed on the outer wall of the rotating rod 41. The fixing member 441 has six rectangular grooves 4411, and an elastic structure is installed inside each groove 4411. The elastic structure can maintain contact with the steel pipe through its own elasticity, thus adapting to steel pipes of different sizes. Specifically, as shown... Figure 4 As shown, the elastic structure includes: rod 442, block 443, elastic element 444, connecting rod 445, connecting seat 446, third plate 447, and cleaning element 448.

[0042] like Figure 4 As shown, rod 442 is circular and is set inside groove 4411 and fixedly connected to fastener 441; block 443 is approximately semi-circular with grooves on its surface, and two of them are symmetrically arranged. Rod 442 passes through block 443, allowing block 443 to slide along rod 442. Block 443 is slidably set inside groove 4411; elastic element 444 is set between the two blocks 443. Elastic element 444 is used to pull the two blocks 443 closer together. Specifically, elastic element 444 is a tension spring, with both ends of the tension spring fixedly connected to block 443, and the tension spring is sleeved around rod 442. By setting tension spring, the blocks 443 can be subjected to the same elasticity, the force transmission is more uniform, and the contact between the elastic structure and the steel pipe is more uniform, compared to It is better to have two springs applying force to block 443 individually; the connecting rod 445 is waist-shaped and there are two of them. The two connecting rods 445 are rotatably connected in the groove of block 443, and the connecting rods 445 are arranged in a figure-eight shape; the connecting seat 446 is composed of two approximately rectangular plates, and the two connecting rods 445 are rotatably connected between the connecting seat 446; the third plate 447 is rectangular and is fixedly installed on the connecting seat 446; the cleaning component 448 is preferably microfiber cloth, which is detachably installed on the third plate 447. The detachable method is that the cleaning component 448 is equipped with a T-shaped insert 449, which slides in the T-shaped groove opened inside the third plate 447, so as to realize the periodic replacement of the cleaning component 448 to ensure the cleaning effect.

[0043] The implementation principle of the continuous steel pipe processing device in this application embodiment is as follows: When the steel pipe is continuously processed, it will pass through the channel 21. At this time, the start drive 34 drives the rotating shaft 35 to rotate. The rotating shaft 35 drives the first gear 36 to rotate. The first gear 36 drives the gear ring 33 to rotate with the help of the bearing 31 and the ring body 32. The gear ring 33 drives the rotating rod 41 to rotate. Simultaneously, the rotating rod 41 rotates by the meshing of the second gear 42 and the gear ring 43, so that the fixed part 441 rotates around the steel pipe while rotating on its own axis. At this time, the elastic part 444 pulls the two blocks 443 closer together. The two blocks 443 respectively drive one end of the connecting rod 445 to move closer to each other. Since the length of the connecting rod 445 is fixed, when one end of the two connecting rods 445 moves closer to each other, the other end of the two connecting rods 445 will push the third plate 447 and the cleaning part 448 to stick tightly to the steel pipes of different sizes with the help of the connecting seat 446. The cleaning part 448 completes the cleaning of the surface of the steel pipe, reducing the impact on subsequent processing.
