Technical Field

[0001] The utility model relates to the technical field of welding assistance, in particular to a steel structure welding assistance device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. During the welding process of steel structure, transport racks are required to assist in the movement and placement of steel structure.

[0003] In the prior art, the steel structure welding auxiliary device can drive the steel structure to move position through a motor and a roller, thereby facilitating the welding equipment to perform welding operations on the steel structure.

[0004] However, during the placement of the steel structure, it is difficult to place the steel structure neatly on the drum only by looking at it with the naked eye, which causes the steel structure to be easily tilted. As a result, the steel structure is easily displaced during the movement, affecting the welding operation of the steel structure by the welding equipment. At the same time, the tilt of the steel structure is not conducive to the subsequent lifting operation. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a steel structure welding auxiliary device, including a support frame 1, a roller 2 and a motor 3, the roller 2 is installed on the inner side of the support frame 1, and the motor 3 is installed on the back of the support frame 1.

[0022] A mounting block 4 is welded to the top of the support frame 1, and a lead screw 5 is connected to the inside of the mounting block 4 through a bearing, and a slider 6 is threadedly connected to the lead screw 5, a slide rod 7 is welded to the outside of the slider 6, a limiting block 8 is welded to the outside of the slide rod 7, and the end of the slide rod 7 is connected to a limiting plate 9, and a guide rod 10 is connected to the side of the limiting plate 9 close to the mounting block 4, and a connecting block 11 is welded to the top of the support frame 1 close to the guide rod 10, and a sliding mechanism is formed between the guide rod 10 and the connecting block 11, and the shape of the guide rod 10 is cylindrical. Embodiment 2

[0023] On the basis of Example 1, in order to achieve the steel structure being placed without tilting, a group of screw rods 5 can be rotated first. When the screw rods 5 rotate, the slider 6 can be driven to slide. When the slider 6 slides, the slide rod 7 can be driven to move. When the slide rod 7 moves, the limit block 8 and the limit plate 9 can be driven to move. When the limit block 8 moves, it can slide with the mounting block 4, and when the limit plate 9 moves, it can drive the guide rod 10 to move. When the guide rod 10 moves, it can slide through the connecting block 11. When one group of limit plates 9 moves to the specified position, another group of screw rods 5 can be rotated so that the spacing between the two groups of limit plates 9 meets the width of the steel structure. Therefore, the steel structure can be directly placed between the two groups of limit plates 9 during the placement process, and the position of the steel structure will not be tilted. When the drum 2 rotates, it can drive the steel structure to move. During the movement of the steel structure, the two groups of limit plates 9 will not cause position displacement and tilt, which is convenient for the welding equipment to perform welding operations on the steel structure. At the same time, after the welding is completed, it is convenient to lift the steel structure.

[0024] A first U-shaped block 12 is welded to the outer side of the support frame 1, and a second U-shaped block 13 is welded to the outer side of the support frame 1 away from the first U-shaped block 12. A connecting shaft 14 is connected to the inside of the first U-shaped block 12, and the connecting shaft 14 is movably connected to a docking block 15. A through hole 16 is opened inside the docking block 15, and a plug-in rod 17 is inserted into the inside of the second U-shaped block 13. The plug-in structure is formed between the plug-in rod 17 and the docking block 15 through the through hole 16. Embodiment 3

[0025] On the basis of the second embodiment, in order to achieve that the two groups of support frames 1 can be stably spliced ​​together, the two groups of support frames 1 can be first brought together so that the first U-shaped block 12 on one group of support frames 1 can be docked with the second U-shaped block 13 on the other group of support frames 1. At this time, the connecting rod 17 can be pulled out from the inside of the second U-shaped block 13, and the docking block 15 can be pulled in the direction of the second U-shaped block 13. When the docking block 15 moves, it can be rotated by the connecting shaft 14. When the docking block 15 rotates and moves to the inside of the second U-shaped block 13, the connecting rod 17 can be inserted into the second U-shaped block 13. At this time, the end of the connecting rod 17 can pass through the docking block 15 through the through hole 16, so that the connecting rod 17 can limit the docking block 15. The connecting rod 17 can prevent the docking block 15 from loosening, so that the two groups of support frames 1 can be stably spliced ​​together. When the support frames 1 are collided, the two groups of support frames 1 are not easy to separate, thereby improving the reliability of the splicing of the two groups of support frames 1.

[0026] In actual use, the steel structure welding auxiliary device uses a lifting device to place the steel structure on the roller 2. When the motor 3 is running, the roller 2 can be driven to rotate by the chain. When the roller 2 rotates, the steel structure can be driven to move. During the movement of the steel structure, the two sets of limiting plates 9 will not cause position displacement and tilt, which is convenient for the welding equipment to perform welding operations on the steel structure. At the same time, after the welding is completed, it is convenient to lift the steel structure. The plug-in rod 17 can limit the docking block 15. The plug-in rod 17 can prevent the docking block 15 from loosening, so that the two sets of support frames 1 can be stably spliced ​​together. When the support frame 1 is hit, the two sets of support frames 1 are not easy to separate, thereby improving the reliability of the splicing of the two sets of support frames 1.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
