[0045] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, each side roller assembly 3 is further provided with a power mechanism 33, which is mounted on the inclined slide table 31 and connected to the side roller 32 to drive the side roller 32 to slide obliquely along the inclined slide table 31. In this embodiment of the present invention, the power mechanism 33 provides power to make the side roller 32 slide obliquely along the inclined slide table 31, so that the side roller 32 fits against the spiral steel pipe 5 to be processed, realizing rapid adjustment of the side roller 32 under different pipe diameters of the spiral steel pipe 5 to be processed, and improving adjustment efficiency.

[0046] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the power mechanism 33 includes a nut 331, a lead screw 332, and a motor 333. The nut 331 is connected to the side roller 32, and the lead screw 332 is located inside the inclined slide 31. The nut 331 is connected to the lead screw 332, and the motor 333 is connected to the lead screw 332. In this embodiment of the invention, the lead screw 332 of the power mechanism 33 is installed inside the inclined slide 31 and connected to the side roller 32 via the nut 331. This facilitates the use of the motor 333 to drive the side roller 32 to move up and down on the inclined slide 31. The power mechanism has a simple structure, stable operation, and enables rapid adjustment of the side roller 32 for different diameters of the spiral steel pipe to be processed.

[0047] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1As shown, a pressure roller assembly 4 is also provided, which is disposed on the base 1 and abuts against the top of the spiral steel pipe 5 to be processed. In this embodiment of the present invention, the pressure roller assembly 4, in conjunction with the bottom roller 2, limits the vertical movement of the spiral steel pipe 5 to be processed, thereby improving the stability of forming and welding during the production process of the spiral steel pipe 5, ensuring welding quality, and improving production efficiency.

[0048] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the pressure roller assembly 4 includes two pressure roller seats 41, two pressure roller columns 42, a crossbeam 43, and pressure roller rollers 44. The two pressure roller seats 41 are respectively located on the lateral sides of the base 1. The bottom end of each pressure roller column 42 is connected to a corresponding pressure roller seat 41. The two ends of the crossbeam 43 are respectively connected to the tops of the two pressure roller columns 42. The pressure roller rollers 44 are located below the crossbeam 43, and the bottom of the pressure roller rollers 44 abuts against the top of the spiral steel pipe 5 to be processed. The pressure roller columns 42 are fixed on the lateral sides of the base 1, and the pressure roller rollers 44 are fixed below the crossbeam 43. The height of the crossbeam 43 can be adjusted according to the diameter of the spiral steel pipe 5 to be processed, so that the pressure roller rollers 44 fit against the top of the steel pipe. The crossbeam 43 is locked by column bolts. The pressure roller assembly of this utility model embodiment has a simple structure and a stable connection. The pressure roller assembly, together with the bottom roller, achieves vertical positioning of the spiral steel pipe 5 to be processed.

[0049] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, each of the pressure roller columns 42 is a telescopic structure, which facilitates the adjustment of the height of the crossbeam 43 according to the diameter of the spiral steel pipe 5 to be processed.

[0050] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 1 As shown, the angle between the inclined surface of the inclined slide 31 and the horizontal direction is 40-50 degrees. The bottom of the inclined slide 31 of this invention is connected and fixed to the base 1, and the inclined slide 31 can extend outward and be suspended in the air. The 40-50 degree horizontal angle greatly reduces the size of the base 1 and makes full use of space.

[0051] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 2As shown, the platform 6 is provided with multiple rows of screw holes 61. These multiple rows of screw holes 61 are spaced apart longitudinally along the spiral steel pipe 5 to be processed on the platform 6. Each row of screw holes 61 can be used for detachable connection with the base 1. In this embodiment of the invention, the platform 6 is provided with multiple rows of screw holes 61 for connecting and fixing the base 1. Furthermore, to prevent the roller of the bottom roller 2 from contacting the outer weld seam 7, multiple rows of screw holes 61 are provided so that the base 1 can move left and right on the platform 6.

[0052] As an optional implementation, in one embodiment of the utility model, see [link to utility model description]. Figure 2 As shown, the spacing between each row of screw holes 61 is greater than the width of the bottom roller 2. In this embodiment of the invention, the platform 6 is provided with multiple rows of screw holes. For ease of adjustment, the spacing a between the platform screw holes is greater than the width b of the bottom roller. When the bottom roller 2 contacts the outer weld seam 7, the base 1 can be moved to the left or right of the adjacent hole to avoid the outer weld seam 7, and the platform 6 is fixed directly below the spiral steel pipe 5 to be processed. The platform 6 and the base 1 are designed and installed to be consistent with the vertical center line of the spiral steel pipe 5 to be processed, and the total height of the platform 6, the base 1, and the bottom roller 2 is the same as the bottom elevation of the spiral steel pipe 5 to be processed. When the side roller 32 and the pressure roller 44 encounter the same situation, the adjustment method is the same, the operation is simple, and it is easy to improve the stability of the limiting device.

[0053] This utility model embodiment also provides a limiting system for online processing of spiral steel pipes, including the aforementioned limiting device for online processing of spiral steel pipes. The limiting device includes a base 1, a bottom roller 2, and two side roller assemblies 3. The base 1 is disposed on a platform 6, the bottom roller 2 is disposed on the base 1, and the two side roller assemblies 3 are disposed opposite each other on the base 1 and located on both sides of the bottom roller 2. Each side roller assembly 3 is provided with an inclined slide 31 and a side roller 32. The side roller 32 is disposed on the inclined slide 31 and can slide obliquely along the inclined slide 31 and be fixed. The bottom roller 2 and the two side rollers 32 are used to limit the left and right directions of the spiral steel pipe 5 to be processed. The base 1, bottom roller 2, and two side roller assemblies 3 of this utility model cooperate to form the limiting system. The bottom roller 2 is located below the spiral steel pipe 5 to be processed, and the two side roller assemblies 3 are respectively located on both sides of the spiral steel pipe 5 to be processed. The side roller 32 of each side roller assembly 3 can slide obliquely along the inclined slide table 31 and be fixed. The bottom roller 2 and the two side rollers 32 cooperate to limit the left and right directions of the spiral steel pipe 5 to be processed, which makes it easy to adjust the distance between the two side rollers 32 according to the pipe diameter of the spiral steel pipe 5 to be processed. There is no need to replace the limiting device, shortening the processing cycle and improving efficiency.
