Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, specifically to an auxiliary roller frame for steel pipe welding. Background Technology

[0002] During steel pipe welding, the use of roller frames provides stable support for the steel pipe, preventing deformation or bending caused by gravity or welding heat. Simultaneously, the support of multiple rollers ensures the steel pipe remains horizontal or vertical during welding, reducing welding stress, improving welding quality, and enabling smooth rotation of the steel pipe during circumferential welding.

[0003] The existing roller frame has a fixed and non-adjustable angle between the two rollers. Therefore, when supporting steel pipes of different diameters, the rollers cannot fit well with the steel pipes, resulting in uneven contact between the rollers and the steel pipes. This leads to instability in the use of the device, poor adaptability, and a decline in welding quality. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] Combined with appendix Figure 1 and Figure 2 As shown, an auxiliary roller frame for steel pipe welding includes a base 1. The base 1 has electric telescopic rods 21 at the four corners. The telescopic ends of the electric telescopic rods 21 are connected to movable wheels 8. The electric telescopic rods 21 can drive the movable wheels 8 to rise and fall. When using the device, the movable wheels 8 are retracted to ensure that the device is placed stably on the ground, thereby ensuring stability during use. When moving, the movable wheels 8 are lowered to raise the base 1 so that the device can be moved, saving the effort of carrying it.

[0029] Combined with appendix Figure 1 and Figure 3As shown, the base 1 is slidably provided with symmetrically arranged roller bracket assemblies. The base 1 is also provided with a drive assembly 1 for driving the two roller bracket assemblies to move towards each other. The drive assembly 1 includes a motor 2 11 fixedly mounted on one side of the base 1. The base 1 is provided with a groove 12. A bidirectional screw 13 is rotatably mounted in the groove 12. One end of the bidirectional screw 13 passes through the base 1 and is connected to the motor 2 11. The support seat 2 is threadedly connected to the bidirectional screw 13. The base 1 is provided with sliding grooves 14 on both sides of the groove 12. The bottom of the support seat 2 is connected with an auxiliary wheel 15. The auxiliary wheel 15 is slidably located in the sliding groove 14. The auxiliary wheel 15 is located on both sides of the support seat 2 to share the force on the bidirectional screw 13, so that the roller bracket assemblies move more smoothly.

[0030] Adjust the spacing of the roller bracket assembly according to the required fixed steel pipe size. Motor 2 11 drives the bidirectional screw 13 to rotate. When the bidirectional screw 13 rotates forward, the roller bracket assemblies on both sides of the base 1 move towards the center of the base 1 to reduce the spacing, so as to fix and support the steel pipe with a smaller diameter. Similarly, when the bidirectional screw 13 rotates in reverse, the spacing of the roller bracket assembly increases to fix the steel pipe with a larger diameter.

[0031] Combined with appendix Figure 3 and Figure 4 As shown, the roller support assembly includes a support base 2, on which uprights 3 are symmetrically arranged. A horizontally placed roller frame 4 is fixed between the two uprights 3, and a roller frame 5 is hinged between the two uprights 3. Two rollers 20 are rotatably arranged on both the roller frame 4 and the roller frame 5. The two rollers 20 are coaxially designed. The design of multiple rollers 20 increases the contact area between the rollers 20 and the steel pipe, thereby improving the stability of the fixed support. The coaxial design also ensures the synchronous rotation of the rollers 20.

[0032] Combined with appendix Figure 3 and Figure 4 As shown, the support base 2 is provided with a drive assembly 2 for driving the roller frame 2 5 to rotate. The drive assembly 2 includes a motor 7 connected to the support base 2. The roller frame 2 5 has a rotating shaft that passes through the upright 3 and is connected to a synchronous pulley 6. A rotating rod is connected to the motor 7. One end of the rotating rod is rotatably connected to the upright 3. A synchronous pulley 2 9 is fixed on the rotating rod. The synchronous pulley 6 and the synchronous pulley 2 9 are connected by a synchronous belt 10.

[0033] Combined with appendix Figure 5 and Figure 6 As shown, a positioning gear 16 is connected to one end of the rotating shaft of the roller frame 2 5. The positioning gear 16 is arranged opposite to the synchronous wheel 1 6. A fixing tube 17 is fixed on the upright frame 3. A retaining tooth 19 that meshes with the positioning gear 16 is connected inside the fixing tube 17 by a spring 18.

[0034] Motor 7 drives the rotating rod to rotate, which in turn drives synchronous pulley 9 to rotate. Synchronous pulley 6 follows synchronous pulley 9 through synchronous belt 10, thereby causing roller frame 5 to rotate and change the angle between it and roller frame 4. During the angle adjustment process, positioning gear 16 rotates with the shaft of roller frame 5. During the rotation of positioning gear 16, locking teeth 19 are subjected to force, and spring 18 continuously extends and retracts, so that locking teeth 19 continuously engage with the tooth groove of positioning gear 16, which can fix the adjusted angle and ensure the stability of roller support 2 after adjustment.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
