The gantry 4 can adjust the lateral position of the welding torch component 5, facilitating welding of different parts. Limiting chutes 8 are provided on the opposite surfaces of the front and rear parts of the two support components 7. Both ends of a U-shaped slider 9 are arranged in the limiting chutes 8. A support frame 12 is provided through the notch of the U-shaped slider 9. Two support frames 12 form a group. Outer support frames 13 are provided on the opposite surfaces of each group of support frames 12. An extension frame 14 is provided at the top of the outer support frame 13. Both extension frames 14 extend out of the opposite surfaces of the two outer support frames 13. The extension frame 14 is limited by the outer support frame 13. The extension frame 14 can perform linear movement on the top of the outer support frame 13. A strong magnetic electromagnet 15 is provided at the end of the extension frame 14. When the two extension frames 14 perform linear movement in opposite directions, the two strong magnetic electromagnets 15 are driven to adjust their positions to ensure that the two strong magnetic electromagnets 15 are located on both sides of the steel structure bridge parts to be welded. After the two strong magnetic electromagnets 15 are energized, the steel structure parts will be adsorbed tightly, facilitating handling. An adjustment block 16 is slidably connected inside the support frame 12. Both ends of a first hydraulic rod 11 are respectively connected to the top end of the adjustment block 16 and the support frame 12. The first hydraulic rod 11 can adjust the height of the outer support frame 13 through the adjustment block 16, facilitating fixing and handling of the steel structure bridge parts. An adjustment frame 21 is provided at the top end of the extension frame 14. Both ends of a second hydraulic rod 20 are respectively connected to the adjustment frame 21 and the outer support frame 13. Both the first hydraulic rod 11 and the second hydraulic rod 20 are controlled by a control box. The second hydraulic rod 20 extends the extension length of the extension frame 14 through the adjustment frame 21 to ensure that the two strong magnetic electromagnets 15 can contact both sides of the steel structure bridge parts.

[0018] Specifically, two long slots 6 matching the support frames 12 are provided through the front and rear parts of the welding carrier table 1. After the two strong magnetic electromagnets 15 fix the steel structure bridge parts to be welded and convey them to the upper part of the welding carrier table 1 through the first hydraulic rod 11, when the U-shaped slider 9 is pushed towards the welding gun assembly 5, the support frames 12 will perform linear motion inside the long slots 6, so that the positions to be welded of the two parts are connected to each other.

[0019] Furthermore, moving components 10 are provided at the four corner positions at the bottom of the welding carrier table 1. The moving components 10 are composed of steel columns and self-locking universal wheels, making it convenient to move the steel structure bridge welding tooling.

[0020] Furthermore, a storage battery 19 is provided at the top of the extension frame 14 near the strong magnetic electromagnet 15. Every two storage batteries 19 in each group are commonly electrically connected to a control circuit to control the power-off and power-on operations of the two storage batteries 19.

[0021] Furthermore, reinforcing vertical rods 17 are provided on both sides of the extension frame 14. Reinforcing grooves 18 matching the reinforcing vertical rods 17 are provided through both sides of the outer support frame 13. The reinforcing vertical rods 17 and the reinforcing grooves 18 are used in combination. The reinforcing grooves 18 reinforce the end of the extension frame 14 to ensure the stability of the extension frame 14.

[0022] Even further, the bottom of each group of support frames 12 extends out of the bottom of the U-shaped slider 9. When the steel structure bridge parts are placed on the ground or other transfer equipment, the outer support frame 13 can be moved inside the support frame 12 to the bottom of the U-shaped slider 9, which is convenient for handling the steel structure parts.

[0023] The usage method of this embodiment is as follows: During welding, move the steel structure bridge welding tooling above the parts of the steel structure bridge. Then, through the control box, operate the first hydraulic rod 11 to drive the adjusting block 16 to adjust the height of the outer support frame 13, so that the outer support frame 13 approaches the parts placed on the ground or the top of the transfer equipment. Then, through another control box, operate the second hydraulic rod 20 to drive the adjusting frame 21 to adjust the extension length of the extension frame 14, so that the two strong magnetic electromagnets 15 are in contact with the parts of the steel structure bridge. Turn on the two storage batteries 19 through the control circuit, so that the two strong magnetic electromagnets 15 tightly adsorb the parts. Then, pull the outer support frame 13 above the welding carrier table 1 through the first hydraulic rod 11, push the U-shaped slider 9 towards the welding torch assembly 5, and then drive the outer support frame 13 through the first hydraulic rod 11 to make the parts located at the top of the welding carrier table 1. Then, perform the same operation through the two support frames 12 and the strong magnetic electromagnets 15 at the rear end of the welding carrier table 1 to move another part to the top of the welding carrier table 1, connect the welding positions of the two parts to be welded, and then perform welding through the welding torch assembly 5. Finally, fix the welded parts through one set of strong magnetic electromagnets 15 and then transport them to the transfer equipment.
