Description

Technical Field

[0001] The utility model relates to the technical field of steel truss welding platforms, and particularly relates to a welding platform for high-altitude welding of steel pipe trusses. Background Art

[0002] With the development of long-span space structures, grid structures have been widely used. For example, grid structures have been applied in buildings such as airport terminals, toll stations, and factories. The grid structure has reasonable stress, strong stiffness, and light weight. It can give full play to the tensile and compressive properties of materials, reduce the adverse effects of bending moment and shear force on materials, and has various shapes. The grid size can be adjusted according to the building's usage requirements to meet different usage needs. Currently, the main material for this structure is steel. During the construction of a steel structure grid factory building, it is necessary to weld process lifting points on the bolt balls or welded balls of the grid roof structure for welding other equipment. Since the steel truss is at a high altitude, a suspension cage or a welding platform is required for auxiliary operations. The traditional suspension cage for steel structure welding is in the form of a single suspension cage. Since the steel pipe truss structure uses round pipes, hanging a single suspension cage on the steel pipe will rotate, making it impossible to effectively maintain body stability, resulting in unguaranteed welding quality, low construction efficiency, and inability to ensure the operation safety of construction workers, thus not meeting the on-site construction requirements. The invention patent with publication number CN108857150A discloses a suspension cage for high-altitude welding construction of a grid, which includes a cage body. The cage body is in the shape of a quadrangular prism. The bottom of the cage body is provided with a bottom plate. A first hook and a second hook are provided on one side wall of the cage body. A third hook is provided on another side wall parallel to the side wall where the first hook and the second hook are located. The first, second, and third hooks all include a bent hook body. The bending directions of the hook bodies of the first hook and the second hook are the same, and the bending direction of the hook body of the third hook is perpendicular to that of the first hook. It can adapt to the high-altitude grid structure, realize the effective hanging of the suspension cage, improve the welding quality, and at the same time improve the safety of construction workers working at high altitudes. However, this suspension cage can only be welded from one side, and the working space is small. Content of the Utility Model

[0003] The purpose of the utility model is to provide a welding platform for high-altitude welding of steel pipe trusses. On the premise of ensuring the stability of the operation, this platform also increases the welding operation range.

[0015] The following further describes the present utility model in conjunction with the accompanying drawings:

[0016] As Figure 1 and Figure 2 shown, a welding platform for high-altitude welding of steel pipe trusses includes a double-hoisting-position cage body 1 and hooks 2 fixedly arranged on the top of the double-hoisting-position cage body 1 by welding or bolts. There are two hooks 2 in total, and the two hooks 2 are arranged on both sides of the top of the double-hoisting-position cage body 1. The hooks 2 are in an inverted U shape and can be hooked on the horizontally arranged steel pipes, and the two hooks 2 are hung on both sides of the node to be welded. The double-hoisting-position cage body 1 is formed by welding a number of square steel pipes.

[0017] On both sides of one end of the double-hoisting-position cage body 1, there are extension parts 3. The double-hoisting-position cage body 1 and the two extension parts 3 are integrally concave, and the vertically arranged steel pipe is located in its concave area. The double-hoisting-position cage body 1 and the extension parts 3 are detachably connected by a connecting member 4. The extension parts 3 are also formed by welding square steel pipes. The connecting member 4 is a connecting steel pipe fixedly arranged at the end of the extension part 3 by fasteners or welding. The connecting steel pipe is inserted into the interior of the double-hoisting-position cage body 1. A plurality of corresponding connecting holes are provided on the connecting steel pipe and the double-hoisting-position cage body 1. A pin is used to pass through the corresponding connecting holes to detachably connect the connecting steel pipe and the double-hoisting-position cage body 1, which is convenient for disassembly and assembly and storage and transportation.

[0018] On the two extension parts 3, there are limit members 5, and the limit members 5 can connect the double-hoisting-position cage body 1 to the steel pipe truss. Specifically, the limit member 5 is a steel pipe detachably installed on the two extension parts 3 by bolts, and the steel pipe truss is constrained between the steel pipe and the double-hoisting-position cage body 1.

[0019] At the bottom of the double-hoisting-position cage body 1, a first bearing plate 6 is fixedly arranged by fasteners or welding. At the bottom of the extension part 3, a second bearing plate 7 is fixedly arranged by fasteners or welding. The first bearing plate 6 and the second bearing plate 7 seal the bottom, which can prevent tools from accidentally falling during operation and improve the safety of operation.

[0020] On the outside of the extension part 3, an auxiliary protective fence 8 is hingedly installed. After the platform is installed on the steel pipe truss, the two auxiliary protective fences 8 are connected by a U-shaped member to block the concave openings of the double-hoisting-position cage body 1 and the two extension parts 3, forming a circumferential protective space. On the side of the extension part 3, a lateral protective member 9 is hingedly arranged. When the two lateral protective members 9 are flattened, the two extension parts 3 can be connected. The operator can move circumferentially around the node to be welded, with a wide operating range, reducing the number of hoisting times and improving the operating efficiency.
