Description

Technical Field

[0001] This invention relates to processing equipment for steel structure components in civil engineering, and particularly to a roller chain support device for producing and processing a platform for assembling irregularly shaped columns made of square steel tube concrete, belonging to the field of steel structure component processing. Background Technology

[0002] The square steel tube concrete composite irregular column system is widely used in multi-story and high-rise steel structure residential buildings. It has the advantages of good architectural effect, flexible structural layout and high degree of prefabrication. Since its introduction, it has received widespread attention. In recent years, with the development of steel structure design level and processing technology in my country, the prefabricated residential steel structure system will surely have a broad prospect.

[0003] A patent has been proposed to provide a horizontal assembly device for a composite irregular column made of square steel tube and concrete. The patent details an overall horizontal assembly platform for the composite irregular column. Any two single columns of the composite irregular column are connected by two connecting plates. When assembling the composite irregular column using this assembly platform, the lower connecting plate can be directly positioned and spot-welded. However, when the upper connecting plate is transported to the designated position, it is suspended in the air and difficult to fix in the corresponding position, which creates an obstacle for the subsequent assembly process.

[0004] Therefore, it is essential to invent a support device that can fix the upper connecting plate and stabilize it in a designated position, so as to ensure the smooth progress of the subsequent assembly process and provide effective protection for the safety and promotion of prefabricated buildings. Summary of the Invention

[0005] Based on the problems existing in the prior art, the present invention describes a roller chain support device for a square steel tube concrete composite irregular column assembly platform. The upper connecting plate is fixed to stabilize it in a designated position, thereby working in coordination with the spot welding device and even the entire assembly platform, improving processing accuracy and production efficiency.

[0006] The technical solution of this invention is summarized as follows:

[0007] 1. The main components of this roller chain support device consist of a steel roller ②, a chain ④, and a steel roller bearing ⑨;

[0008] 2. One end of the roller chain support device is fixed on the assembly platform device, and the other end is freely placed on the part of the lower connecting plate ⑥ of the combined irregular column that has been spot-welded to the single limb ⑤ of the combined irregular column. At this position, it supports the upper connecting plate ③ of the combined irregular column, and the unsupported part hangs down naturally.

[0009] 3. Take the example of the combination of special-shaped column single limb (5) with the outer diameter of 150 mm square steel pipe, the axial distance between the upper connecting plate (3) and the lower connecting plate (6) of the combination of special-shaped column is 120 mm when the combination of special-shaped column is processed, and the thickness of the upper connecting plate (3) and the lower connecting plate (6) of the combination of special-shaped column is 10 mm, so the net distance between the two is 110 mm, at this time the outer diameter of the roller (2) is defined as 110 mm, and the supporting function ensures the accurate positioning of the upper connecting plate (3) of the combination of special-shaped column;

[0010] 4. With the progress of the assembly process, the roller chain is stationary, the combination of special-shaped column single limb (5), the lower connecting plate (6) of the combination of special-shaped column and the upper connecting plate (3) of the combination of special-shaped column are constantly moving forward and sliding on the roller (2). BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 : Schematic diagram of roller chain support device;

[0012] Figure 2 : Cross-sectional view of roller chain support device;

[0013] It includes: chain fixed end ①, steel roller ②, combination of special-shaped column upper connecting plate ③, chain ④, combination of special-shaped column single limb ⑤, combination of special-shaped column lower connecting plate ⑥, assembly platform ⑦, chain free end ⑧, steel roller bearing ⑨, wherein the steel roller ②, chain ④ and steel roller bearing ⑨ together constitute the main part of the roller chain support device. DETAILED DESCRIPTION

[0014] The invention will be further described below in conjunction with the drawings of the specification.

[0015] 1. The end of the chain ④ is fixed to the device, and the combination of special-shaped column upper connecting plate ③ passes through this point during the assembly process;

[0016] 2. A steel roller bearing ⑨ is arranged every 220 mm on the chain ④, and a steel roller ② with an outer diameter of 110 mm is installed on the steel roller bearing ⑨, the free end of the steel roller ② is placed on the combination of special-shaped column lower connecting plate ⑥, and plays a supporting role to the combination of special-shaped column upper connecting plate ③, since the outer diameter of the steel roller ② and the net distance between the upper and lower connecting plates after the special-shaped column is processed are equal, it plays a double role of supporting and positioning;

[0017] 3. During the assembly process, the positions of the chain ④, the steel roller bearing ⑨ and the steel roller ② remain unchanged, the combination of special-shaped column lower connecting plate ⑥ and the combination of special-shaped column single limb ⑤ are completed at the previous position and are driven to form a whole, at this time the combination of special-shaped column upper connecting plate ③ is not connected with the whole;

[0018] 4. The combined special-shaped column upper connecting plate ③ is driven to the roller chain device, and reaches the predetermined position under the support and positioning action of the roller chain device, and the combined special-shaped column whole and the combined special-shaped column upper connecting plate ③ are spot-welded and assembled, and continuously forward.
