Description

Technical Field

[0001] The utility model relates to the technical field of steel structure clamping, in particular to a clamping device for building steel structures. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to rust, and general steel structures need to be derusted, galvanized or painted, and need to be maintained regularly. Clamping devices are required during the painting process of steel structures. However, traditional steel structure clamping devices can only clamp steel structures with a single size, resulting in a reduced applicability of the clamping device;

In the utility model, while the rotating mechanism drives the steel structure to rotate, the steel structure is rotated and moved for painting through the mutual cooperation with the painting mechanism. The rotating mechanism clamps both ends of the steel structure to be painted through a clamping assembly, and then drives the clamping assembly and the steel structure to be painted to rotate through a gear driving assembly. Then, the painting mechanism drives the painting assembly to move through a screw driving assembly, and moves and paints the rotating steel structure to be painted, realizing automatic and uniform painting of the steel structure and improving the usability of the device;

[0004] There are still some problems in the above patent during use. The positions of the rotating mechanism and the clamping assembly in the above patent cannot be moved, so the distance between the two clamping assemblies cannot be adjusted. If a relatively short steel plate or other short steel structures are faced, effective clamping cannot be carried out; Therefore, we need to propose a clamping device for building steel structures.

Detailed Description of the Preferred Embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The utility model provides: a clamping device for building steel structures, as Figures 1-4As shown in the figure, it includes an installation base plate 1 and a support plate 2 installed on the side of the installation base plate 1. A paint spraying box 3 is slidably arranged on the upper surface of the support plate 2. A rotating column 5 is rotatably arranged inside the installation base plate 1. Two groups of moving blocks 4 are symmetrically arranged inside the installation base plate 1 and on the outer arc surface of the rotating column 5. The upper surfaces of the two groups of moving blocks 4 are fixedly installed with connecting plates 8;

[0025] Clamping components 7 for clamping steel structures are arranged on the corresponding surfaces of the two groups of connecting plates 8;

[0026] Both groups of clamping components 7 include two groups of clamping plates 6. Clamping grooves 19 are formed on the corresponding surfaces of the two groups of clamping plates 6. The servo motor 9 drives the rotating column 5 to rotate. The rotating column 5 drives the two groups of moving blocks 4 to move in opposite or relative directions through two groups of threads with opposite outer arc surfaces. Then, the two groups of clamping components 7 are driven to move through the moving blocks 4, so as to adjust the distance between the two groups of clamping components 7. Then, the two groups of clamping plates 6 are driven by the clamping components 7 to clamp and spray paint steel structures of different lengths. And when the steel structure needs to be erected for spraying paint, the steel structure is clamped into the clamping grooves 19, and then the paint spraying box 3 sprays paint on the steel structure, so as to ensure the stability of the steel structure spraying process and improve the applicability of the clamping device for steel structures at the same time.

[0027] Preferably, the two groups of clamping components 7 further include clamping motors 10, mounting plates 11, driving gears 14, driven gears 15 and transmission modules. The mounting plates 11 are fixedly connected with the corresponding connecting plates 8. The clamping motors 10 are bolted to the sides of the mounting plates 11 away from the support plate 2. The driving gears 14 and the driven gears 15 are rotatably arranged on the sides of the mounting plates 11 close to the support plate 2. The driving gears 14 are meshed with the driven gears 15. The driving gears 14 are key-connected to the output ends of the clamping motors 10. The output ends of the clamping motors 10 are key-connected with rotating shafts. The rotating shafts rotate through the mounting plates 11 and are fixedly connected with the driving gears 14. Thus, when the clamping motors 10 are started, the driving gears 14 are driven to rotate. The driving gears 14 drive the driven gears 15 to rotate through the teeth on the outer arc surfaces.

[0028] It should be noted that the transmission module includes an extension rod 12, a driving rod 16, a connecting rod 17 and an auxiliary rod 18, and there are two sets of the extension rod 12, the driving rod 16, the connecting rod 17 and the auxiliary rod 18. The two sets of driving rods 16 are respectively fixedly connected to the driving gear 14 and the transmission gear 15. The two sets of connecting rods 17 are respectively rotatably connected to the two sets of driving rods 16. The two sets of extension rods 12 are fixedly connected to one end of the corresponding connecting rod 17, and the two sets of clamping plates 6 are fixedly connected to the corresponding extension rods 12. When the clamping motor 10 drives the driving gear 14 to rotate counterclockwise, it drives the driving rod 16 to rotate counterclockwise. The driving rod 16 drives the connecting rod 17 to move downward, and the connecting rod 17 drives the clamping plate 6 to move downward through the extension rod 12. The driving gear 14 drives the transmission gear 15 to rotate through meshing. Similarly, the transmission gear 15 drives the other set of clamping plates 6 to move upward, so as to clamp the steel structure by the two sets of clamping plates 6.

[0029] Furthermore, one end of the two sets of auxiliary rods 18 is respectively rotatably connected to the corresponding connecting rod 17, and the other ends of the two sets of auxiliary rods 18 are both rotatably arranged on the side surface of the mounting plate 11. Since both the driving rod 16 and the auxiliary rod 18 are rotatably connected to the connecting rod 17, the angle of the connecting rod 17 can be ensured to keep the clamping plate 6 in a horizontal state, and further ensure that the two sets of clamping plates 6 can clamp the steel structure stably.

[0030] Moreover, two sets of external threads with opposite directions are provided on the outer arc surface of the rotating column 5, and the two sets of moving blocks 4 are respectively threadedly connected to the two sets of external threads. The two sets of external threads are symmetrically arranged on the outer arc surface of the rotating column 5, and the two sets of moving blocks 4 are symmetrically sleeved on the outer arc surface of the rotating column 5. Thus, when the rotating column 5 rotates, the displacement distances of the two sets of moving blocks 4 are kept consistent, so as to drive the two sets of moving blocks 4 to move closer or away from each other, and further make the whole clamping assembly 7 suitable for steel structures with different lengths.

[0031] Specifically, a servo motor 9 is bolted to one end of the mounting base plate 1, and the rotating column 5 rotatably penetrates through the mounting base plate 1 and is key-connected to the output end of the servo motor 9. By connecting the rotating column 5 to the servo motor 9, the servo motor 9 is started to drive the rotating column 5 to rotate, and the rotating column 5 drives the two sets of moving blocks 4 to move through the external threads.

[0032] In addition, the two sets of moving blocks 4 are both set as convex blocks, and moving grooves 13 corresponding to the two sets of moving blocks 4 are opened inside the mounting base plate 1. The moving blocks 4 are set as convex blocks and are clamped into the moving grooves 13, so as to ensure that the rotating column 5 can drive the moving blocks 4 to move inside the moving grooves 13 when rotating, and ensure that the two sets of moving blocks 4 do not rotate with the rotating column 5, and further ensure the stability during the adjustment of the two sets of clamping assemblies 7.

[0033] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
