Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical and electrical installation auxiliary equipment, and particularly relates to a modular steel structure welding auxiliary device. BACKGROUND

[0002] With the rapid development of modern architecture and industry, large steel structural members are increasingly widely used in bridge, factory building, stadium and other engineering projects. These large steel structural members are usually too large in size and heavy in weight to be transported or hoisted in one piece, and thus need to be manufactured and spliced and welded in segments at the construction site. Traditional steel structure field welding operations usually rely on manual or simple mechanical equipment to center, position and support the steel structure.

[0003] However, the prior art has many deficiencies in the field welding of large steel structures. First, the weight of the steel structural member often reaches tens of tons or even hundreds of tons, and it is almost impossible to accurately center and butt joint by relying on manual work, which greatly depends on the lifting cooperation of hoisting equipment. However, due to the size and weight of the steel structural member, the shaking and displacement during hoisting are difficult to accurately control, resulting in difficulty in accurately aligning the two steel structures at one time.

[0004] Secondly, even if the initial butt joint can be achieved by manual work and hoisting equipment, due to the deflection and deformation of the steel structural member, there may still be a small misalignment and gap at the end. Furthermore, the traditional field welding equipment is usually a monolithic structure with single function or imperfect combined function, lacking modular design concept. This makes the equipment extremely inconvenient during transportation, installation and disassembly, and has poor universality, making it difficult to adapt to steel structural members of different sizes and types.

[0005] How to solve the above technical problems is the subject faced by the present application. SUMMARY

In the first winch type driving structure, the opposite driving unit 660-4 drives two driving winches 660-3 through the driving shaft 660-2, and drives the driving connecting piece 660-1 hook connected to the reference butt joint 512 to move towards each other by winding the driving rope, so as to realize the control of the opposite movement of the steel structure. In the second screw type driving structure, the driving screw 6603 with opposite threads drives the first sliding seat 6601 and the second sliding seat 6602 to move towards each other at the same time when it rotates, and the purpose is to transmit the movement to the driving connecting piece 660-1 through the first connecting rod 6604 and the second connecting rod 6605, so as to drive the two steel structures to accurately approach. Both of the two driving methods can realize stable and controllable opposite movement while ensuring high precision, so as to ensure the butt joint quality before welding, which is one of the core technical advantages of the present application.
