Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a clamping device for welding steel structures. Background Technology

[0002] Steel structure welding is a core technology in the manufacturing and installation of steel structures, involving the connection of steel components into a whole using welding materials through heating, pressurization, or a combination of both. It utilizes heat sources such as electric arcs or gas flames to melt the metal at the welding point, forming a molten pool. After cooling, a strong joint is formed, achieving a permanent connection between steel materials and ensuring the overall structural performance. The welding quality directly determines the strength, stiffness, and safety of the steel structure, requiring strict control of welding process parameters and the use of non-destructive testing to detect defects such as cracks and porosity. Widely used in steel structure projects such as factories, bridges, and high-rise buildings, it is a key means to achieve large-span, lightweight steel structure designs. However, current clamps are used to hold the steel structure during welding.

[0024] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a clamping device for steel structure welding.

[0025] A clamping device for steel structure welding includes a base 1 and casters 2, the casters 2 being mounted on the base 1. It also includes an adjustment mechanism mounted on the base 1 for adjusting the fixed position. The adjustment mechanism includes a mounting housing 3 mounted on the base 1 and fixedly connected to it; a mounting plate 4 mounted on the mounting housing 3 for component mounting; two electric telescopic rods 17, both mounted within the mounting plate 4 and fixedly connected to it; a connecting plate 5 located at the output end of the electric telescopic rods 17 and fixedly connected to them; a first motor 6 located within the connecting plate 5 and fixedly connected to it; and a fixing plate 7 located at the output end of the first motor 6 and fixedly connected to it.

[0026] With this setup, when working, the second motor 13 is started, and the first motor 6 drives the fixed plate 7 to rotate, allowing the fixed plate 7 to contact the steel structure.

[0027] refer to Figure 1 and Figure 2 In a preferred embodiment, the adjustment mechanism further includes: a reinforcement device, mounted on the electric telescopic rod 17, for reinforcing the steel structure for stable operation; and a lifting device, mounted inside the mounting housing 3, for lifting the mounting plate 4.

[0028] refer to Figure 5 In a preferred embodiment, the reinforcement device includes: a sliding member 8, which is disposed on the electric telescopic rod 17 and slidably connected to the electric telescopic rod 17; and an electric slider 9, which is disposed inside the sliding member 8 and slidably connected to the sliding member 8.

[0029] refer to Figure 5 In a preferred embodiment, the reinforcement device further includes: a cylinder 10, which is disposed on the electric slider 9 and fixedly connected to the electric slider 9; and a reinforcement plate 11, which is disposed on the output end of the cylinder 10 and fixedly connected to the output end of the cylinder 10.

[0030] With this configuration, during operation, the electric slider 9 slides within the sliding member 8, driving the cylinder 10 and the reinforcing plate 11 to move to the appropriate position. The cylinder 10 pushes the reinforcing plate 11 to reinforce the long steel structure, ensuring its stability during the welding process and preventing shaking or other issues that could affect the welding quality.

[0031] refer to Figure 3 In a preferred embodiment, the lifting device includes: a mounting part disposed on the mounting shell 3 for component mounting; and a lifting part disposed on the mounting part for lifting operations.

[0032] refer to Figure 2 and Figure 3 In a preferred embodiment, the mounting part includes: a fixing ring 12, which is disposed on the mounting shell 3 and fixedly connected to the mounting shell 3; a plurality of stabilizing rods 15, which are disposed inside the mounting shell 3 and fixedly connected to the mounting shell 3; and a second motor 13, which is disposed inside the fixing ring 12 and fixedly connected to the fixing ring 12.

[0033] refer to Figure 3 In a preferred embodiment, the lifting unit includes: a threaded rod 14, which is disposed on the output end of the second motor 13 and fixedly connected to the output end of the second motor 13; and a lifting plate 16, which is disposed on the threaded rod 14 and threadedly connected to the threaded rod 14.

[0034] With this setup, during operation, the second motor 13 drives the threaded rod 14 to rotate according to the height of the long steel structure. Since the lifting plate 16 is connected to the threaded rod 14 by threaded transmission, the lifting plate 16 will move up and down along the threaded rod 14 during the rotation of the threaded rod 14, thereby pushing the mounting plate 4 to rise and fall to accommodate long steel structures of different heights.

[0035] This device, with its adjustment mechanism, can flexibly adjust the fixed position and reinforcement points according to the specific dimensions and welding location of long steel structures. Moving the weld points eliminates the need for frequent disassembly and reassembly of fixtures, reducing operational difficulty and making it particularly suitable for continuous welding operations on long steel structures. Furthermore, the adjustment mechanism allows for real-time adjustment of the steel structure's position during welding, ensuring welding accuracy and efficiency. This adaptability to various working scenarios further enhances its ease of use and practicality.

[0036] Working Principle: In use, this device drives the threaded rod 14 to rotate via the second motor 13, based on the height of the long steel structure. Since the lifting plate 16 is threadedly connected to the threaded rod 14, it moves up and down along the threaded rod 14 during rotation, thus pushing the mounting plate 4 to rise and fall to accommodate long steel structures of varying heights. Then, the electric telescopic rod 17 can adjust the position of the connecting plate 5 as needed, thereby adjusting the position of the fixing plate 7. When the electric telescopic rod 17 moves the fixing plate 7 to the other end of the steel structure, the second motor is activated, and the first motor 6 drives the fixing plate 7 to rotate, allowing it to contact the steel structure. Afterward, the electric telescopic rod 17 retracts, allowing the fixing plate 7 to... The base 1 is used to fix the steel structure, and the welding position is left between the two electric telescopic rods 17. Then, the reinforcement device works, the electric slider 9 slides in the sliding part 8, driving the cylinder 10 and the reinforcement plate 11 to move to the appropriate position. The cylinder 10 pushes the reinforcement plate 11 to reinforce the long steel structure, ensuring its stability during the welding process and avoiding shaking that may affect the welding quality. When moving after welding, the electric telescopic rod 17 and the cylinder 10 work to prevent the fixing plate 7 and the reinforcement plate 11 from detaching from the steel structure. Then, the device is moved to the next welding point, and the above fixing process is repeated for welding. When moving the welding point, there is no need to disassemble the device on a large scale, making it more convenient to use.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
