[0002] Currently, most existing methods for welding longitudinal seams of steel pipes involve welding on the ground, which cannot effectively fix the position. Some methods involve welding by having the welding machine move along a trapezoidal track, but the trapezoidal track placed on the longitudinal seam of the steel pipe cannot be precisely aligned. During the welding process, the weld is prone to deformation, which reduces the quality of the weld and the finished product. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] This embodiment provides a walking platform device for longitudinal seam welding of large-diameter steel pipes, comprising:

[0024] The roller frame has a recessed steel pipe placement area 11 and first rollers 13 on both sides to support the steel pipe 12.

[0025] The walking frame has a guide rail 10 at its bottom, and a left and right movable column 14 is slidably connected to the guide rail. A right and left movable platform 15 is slidably connected to the left and right movable column 14.

[0026] The roller frame is located on one side of the traveling frame, and the vertical moving platform 15 is located directly above the roller frame in the vertical direction.

[0027] Furthermore, the left and right movable column 14 includes a column main frame 141, a horizontal support plate 142 is provided on the column main frame 141, and a number of second rollers 143 are provided below the horizontal support plate 142. The second rollers 143 are distributed in a straight line on the guide rail, and one of the second rollers 143 is connected to the reducer drive device 16.

[0028] The top of the left and right movable column 14 is equipped with an electric winding mechanism 17. The output end of the electric winding mechanism 17 pulls the rope 18 to connect to the upper and lower movable platform 15, thereby controlling the lifting and lowering of the upper and lower movable platform 15.

[0029] Implementation method:

[0030] Start the reducer drive device 16 to drive the second roller 143 to rotate, thereby controlling the movement of the left and right moving column 14;

[0031] Restart the electric winding mechanism 17, control the vertical moving platform 15 to rise and fall, move to the top of the steel pipe 12 on the fixed position roller frame, and stop the reducer drive device 16 and the electric winding mechanism 17.

[0032] After completing the preparatory work, start the welding machine to weld the longitudinal seam of the steel pipe 12;

[0033] Start the reducer drive device 16 to drive the second roller 143 to rotate, thereby controlling the left and right moving column 14 to move the welded longitudinal seam;

[0034] During the welding process, adjust the welding performance of the welding machine and the moving speed of the left and right moving column 14 to achieve seamless coordination and improve the quality of the weld.

[0035] When the longitudinal seam welding is about to be completed, prepare to stop moving and welding, and be quick, accurate and steady.

[0036] After the entire welding process is completed, move the left and right movable column 14 to one side;

[0037] The crane operator was directed to use the crane to lift the welded steel pipe 12 to the storage location;

[0038] Clean up the welding slag and debris generated during welding, and prepare to weld the next steel pipe 12.

[0039] It should be noted that the stability of the left and right movable column 14 during the movement process is related to the size of the roller, the contact area with the guide rail, and the overall height of the left and right movable column 14. In order to avoid possible tipping or instability during the movement process, this embodiment provides a slot 19 on one side of the roller frame, and one side of the transverse support plate 142 is inserted into the slot 19.

[0040] With the cooperation of the slot 19 and the horizontal support plate 142, the left and right moving column 14 is stable during the movement and will not tip over. For the stability of the equipment, a counterweight is added inside the roller frame in this embodiment.

[0041] The direct contact between the transverse support plate 142 and the slot 19 results in significant friction as the transverse support plate 142 moves along with the left and right moving columns 14. This embodiment further improves upon this by addressing the issue of friction.

[0042] The transverse support plate 142 located in the slot 19 is provided with a number of slots, and a third roller 20 is provided in the slot. The third rollers 20 are arranged in an alternating pattern, with some of the third rollers 20 contacting the top surface of the slot 19 and the other part of the third rollers 20 contacting the bottom surface of the slot 19.

[0043] In this embodiment, the output end of the electric winding mechanism 17 pulls the rope 18 connected to the upper and lower moving platform 15, controlling the lifting and lowering of the upper and lower moving platform 15. Since the rope 18 is attached to the upper surface of the upper and lower moving platform 15, the forces on the upper, lower, left, and right sides may be different during the pulling process, and the upper and lower moving platform 15 may tilt. Therefore:

[0044] The side wall of the vertical moving platform 15 is provided with auxiliary rollers 21, which are in contact with the side wall of the left and right moving columns 14.

[0045] The auxiliary rollers 21 on the same side are provided in two sets, located above and below the vertical moving platform 15 respectively, and both sets of auxiliary rollers 21 are in contact with the side walls of the left and right moving columns 14.

[0046] With the support of the auxiliary rollers 21, the vertical moving platform 15 moves more smoothly under the tension of the ropes 18.

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
