Description

[0001] The invention relates to the technical field of steel material processing, in particular to an integrated steel structure correction welding device. Background Art

[0002] Steel structures are usually composed of columns, beams, trusses, plates and other components made of steel plates and steel sections. The various parts are spliced ​​together by welding, riveting or bolting to form the main frame of the building. Therefore, when assembling H-shaped steel, an integrated steel structure correction welding device is required to ensure that the assembled steel structure meets the requirements of the drawings.

[0003] Although the existing integrated steel structure correction welding device can temporarily fix the two steel columns using structures such as fixers, positioning plates and inner support components, it is necessary to insert the positioning plate between the two H-shaped steels before welding the two H-shaped steels. After the wing plate is welded, the positioning plate needs to be knocked out. When the positioning plate is knocked, it is easy to affect the quality of the weld after the wing plate is welded, and it is easy to destroy the beauty of the weld, resulting in the quality of the two H-shaped steels after welding, affecting the subsequent use.

[0041] By adopting the above technical solution:

[0042] When in use, when the two H-shaped steels move along the surface of the bottom plate 1, the H-shaped steel is brought into contact with the transmission roller 610, and the transmission roller 610 drives the H-shaped steel to move to the top of the mounting block 603, so that the joint of the H-shaped steel moves between the two extension parts, and the second threaded rod 607 is rotated. The second threaded rod 607 cooperates with the lifting plate 604 to drive the lifting plate 604 to move downward, so that the lifting plate 604 drives the locking plate 606 to move downward, and the locking plate 606 drives the extension part to move downward, so that the extension part presses the wing plate at the bottom of the H-shaped steel, and at the same time, the top of the second threaded rod 607 contacts the lower surface of the wing plate at the bottom of the H-shaped steel, and the wing plate at the top of the H-shaped steel is welded by a welding gun. While the wing plate at the bottom of the H-shaped steel is pressed by the extension of the locking plate 606, the top of the second threaded rod 607 is used to support the connection of the H-shaped steel, and the H-shaped steel is corrected and welded.

[0046] When in use, when the H-shaped steel moves to the inside of the extension part, the bottom of the power plate 710 contacts the wing plate on the top of the H-shaped steel. When the H-shaped steel is in a tilted state, the H-shaped steel drives the power plate 710 to rotate, so that the power plate 710 drives the transmission column 708 to rotate around the connecting rod 706, and the transmission column 708 drives the inclined plate 709 to rotate around the rotating disk 707. At the same time, the transmission column 708 drives the protractor 711 to rotate, so that an angle is formed between the 0 scale line of the protractor 711 and the pointer 712.

At the same time, a disc can be installed at the end of the first threaded rod 4 away from the positioning block 3. The first threaded rod 4 is limited by the disc installed on the first threaded rod 4 to prevent the first threaded rod 4 from separating from the pressure plate 5 when moving.

[0054] By adopting the above technical solution:

[0055] When in use, pull the locking rod 601, so that the locking rod 601 drives the wedge block to move, so that the locking rod 601 and the wedge block are separated from the bottom plate 1.
