Description

Technical Field

[0001] This utility model relates to the field of steel structure welding technology, specifically a multi-angle positioning bracket for welding steel support structures. Background Technology

[0002] With its advantages of high strength, light weight, and good toughness, steel structure has become the core supporting component in high-rise and super high-rise buildings, tunnel support, bridge engineering and other fields. Steel support structures are mostly made of steel beams, steel columns, steel trusses and other components, which are welded together. The quality of the welding directly determines the stability and safety of the overall project. At the same time, with the increasing diversification of building shapes, a large number of complex steel support structures such as irregular curtain wall keels and tunnel arch steel frames have emerged. These structures require frequent multi-angle butt welding.

[0003] Existing multi-angle positioning brackets for welding steel support structures require opening the positioning structure and flipping it with external tools after welding one side. During the flipping process, joint misalignment is prone to occur, affecting the welding effect. Therefore, a multi-angle positioning bracket for welding steel support structures is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-angle positioning bracket for welding steel support structures, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-angle positioning bracket for welding steel support structures includes a base and a support frame. The support frame is fixedly connected to the top of the base. Limiting grooves are formed on both sides of the support frame. Limiting sliders are provided inside the limiting grooves. Motors are fixedly connected to the sides of the two limiting sliders that are furthest from each other. A rotating shaft passing through the limiting sliders is fixedly connected to the output end of the motor. A support plate is fixedly connected to the end of the rotating shaft furthest from the motor. A fixed shell is fixedly connected to the side of the support plate furthest from the rotating shaft. A telescopic rod is provided inside the fixed shell. A driving component located inside the limiting groove is fixedly connected between the base and the limiting sliders. A positioning hole is formed at the top of the telescopic rod. The interior of the fixed shell... The telescopic rod is threaded with a bolt that passes through the positioning hole. A fixed frame is fixedly connected to the end of the telescopic rod away from the support plate. The inner side of the fixed frame has symmetrically arranged limiting grooves. A limiting block is provided inside the limiting groove. A limiting plate located inside the fixed frame is fixedly connected between a pair of limiting blocks. A threaded adjusting rod is threadedly connected inside the fixed frame. A limiting plate fixedly connected to the threaded adjusting rod is rotatably connected inside the limiting plate. A fixing clamp is fixedly connected to the side of the limiting plate away from the telescopic rod. An anti-slip pad is fixedly connected between a pair of fixing clamps. A symmetrically arranged spring telescopic rod is fixedly connected to the top of the base. A support ring is fixedly connected to the top of the spring telescopic rod.

[0007] Preferably, the inner shape of the limiting groove matches the shape of the limiting slider, and the inner side of the limiting groove and the outer side of the limiting slider fit together.

[0008] Preferably, the inner shape of the limiting groove matches the shape of the limiting block, both being rectangular, and the inner side of the limiting groove and the outer side of the limiting block fit together.

[0009] Preferably, the spring telescopic rod and the support ring are a set, and there are two sets in total. The spring telescopic rod and the support ring are symmetrically arranged between the base and the support frame.

[0010] Preferably, there are several positioning holes, which are evenly spaced inside the telescopic rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the steel support structure can be raised and lowered by the set support frame, limiting slide groove, limiting slider, motor, rotating shaft, driving component, support ring and spring telescopic rod. At the same time, it can automatically drive the steel support structure to rotate and flip freely. Under the action of the spring telescopic rod and support ring, the flipped steel support structure is guided and supported, making the flipping process more stable. There is no need to open the positioning structure. After the flipping is completed, the operation can continue. It avoids misalignment at the connection and does not require secondary fixing, which is more convenient and faster. This solves the problem that in the process of welding multi-angle positioning brackets for steel support structures, after welding one side, the positioning structure needs to be opened and external tools are used to flip it. During the flipping process, the joint is prone to misalignment, which affects the welding effect.

[0013] 2. In this utility model, the fixed shell, telescopic rod, positioning hole and bolt and other components can greatly improve the practicality of the positioning structure, and can be used for welding steel support structures of more sizes, effectively improving the compatibility of the equipment.

A fixed shell 8 is fixedly connected to the side of the support plate 7 that is far away from the rotating shaft 6. A telescopic rod 9 is provided inside the fixed shell 8. A driving component 10 located inside the limiting grooves 3 is fixedly connected between the base 1 and the limiting sliders 4. A positioning hole 11 is formed at the top of the telescopic rod 9. A through positioning hole is threaded inside the fixed shell 8. Bolt 12 of 11 is used to fix a fixed frame 13 to the end of the telescopic rod 9 away from the support plate 7. The inner side of the fixed frame 13 is provided with symmetrically arranged limiting grooves 14. The inner side of the limiting groove 14 is provided with limiting blocks 15. A limiting plate 16 located inside the fixed frame 13 is fixedly connected between a pair of limiting blocks 15. A threaded adjusting rod 17 is threadedly connected inside the fixed frame 13. A limiting plate 18 fixedly connected to the threaded adjusting rod 17 is rotatably connected inside the limiting plate 16.

[0026] Workflow: When a multi-angle positioning bracket for welding a steel support structure is required, the entire system is powered externally and controlled by an external controller. First, the bracket is disassembled by rotating bolt 12. Then, under the guidance of the fixed housing 8, components such as the telescopic rod 9, fixed frame 13, fixed clamping block 19, and anti-slip pad 20 are moved. Adjustments are made according to the required dimensions of the steel support structure. After adjustment, the bracket is fixed by bolt 12. The steel support structure to be welded is then placed between the fixed clamping blocks 19. After placement, the steel support structure is fixed by rotating the threaded adjusting rod 17. The spring telescopic rod 21 and support ring 22 provide additional support from below, making the rotation of the steel structure more stable. After that, the fixed steel support structure can be welded. After one side is welded... The driving component 10 drives the limiting slider 4 to move downward under the guidance of the limiting groove 3, so that the steel support structure and the support ring 22 are in contact. Under the action of the spring telescopic rod 21, the support ring 22 can provide support and guidance during the flipping process of the steel support structure. The output end of the motor 5 drives the rotating shaft 6, support plate 7, fixed shell 8, telescopic rod 9, fixed frame 13, limiting plate 16, fixed clamp 19 and anti-slip pad 20 to rotate. The fixed clamp 19 drives the steel support structure to flip. The support ring 22, under the action of the spring telescopic rod 21, can guide the steel support structure and provide further auxiliary support for the steel support structure during the flipping process. This can effectively avoid workers welding overhead and can complete the welding in a normal posture, effectively ensuring the welding quality.
