Description

Technical Field

[0001] This invention relates to the field of steel bar processing technology, and more particularly to a positioning device for welding steel mesh. Background Technology

[0002] A box girder is a type of beam used in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, resembling a box, hence the name.

[0003] The edges of the box girder are solid, while the interior is hollow. The hollow interior reduces the production and transportation costs of the box girder. However, the hollow structure concentrates the stress on the edges of the box girder. Therefore, the edges of the solid structure generally require a large number of steel bars to form a steel mesh for support. Since the external structure of the box girder is generally U-shaped, the steel mesh supporting the box girder is generally formed by welding U-shaped ring steel bars and longitudinal steel bars perpendicular to the U-shaped plane.

[0004] To improve the production efficiency of U-shaped steel mesh, various splicing equipment has emerged. However, it has been found that when the ring bars and longitudinal bars are lapped, due to the elasticity and gravity of the bars themselves, if the position of the U-shaped ring bars and longitudinal bars is restricted by limiting the position of the bars, the self-weight and elasticity of the longitudinal bars will cause the welding position to shift when the limit is too loose, resulting in inconsistent welding points of the produced U-shaped steel mesh. When the limit is too strict, the positions of the ring bars and longitudinal bars are prone to collision, leading to mechanical failure.

[0005] In conclusion, there is an urgent need for a positioning device for welding steel mesh to solve the above problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a positioning device for welding steel mesh. This device solves the problems encountered in the production of U-shaped steel mesh when, during the overlapping of ring and longitudinal steel bars, the position of the ring and longitudinal steel bars is limited by a loose limit. When the limit is too loose, the weight and elasticity of the longitudinal steel bars cause the welding position to shift, resulting in inconsistent weld points in the produced steel mesh. Conversely, when the limit is too strict, the ring and longitudinal steel bars are prone to collision.

[0054] To restrict the position of the 95° ring reinforcement, such as Figure 12 As shown, the gripper 49 is provided with a first locking block 491 and a second locking block 492. The first locking block 491 and the second locking block 492 can rotate towards each other under the action of the fourth driving member 45, thereby locking the annular steel bar 95.

[0055] Due to varying on-site operating environments, the clamping positions for the 95mm ring reinforcement also differ, providing more possibilities for the clamping positions of the 95mm ring reinforcement, such as...

[0058] To ensure accurate lap joints between the top row of reinforcing bars 91 and the ring reinforcing bars 95 in U-shaped steel meshes of different sizes, such as Figure 8 As shown, an eighth support plate 64 is provided inside the upper row limiting component 6. The eighth support plate 64 is fixedly installed at the bottom of the first inclined beam 11. A cylinder 65 is installed on the top of the eighth support plate 64. A seventh support plate 62 is movably installed on one side of the eighth support plate 64.

A movable block 68 is connected to one side of the push block 66. The operation of the ninth driving component 67 drives the movable block 68 to rotate, which cooperates with the fixing block 69 to engage the upper row of reinforcing bars 91.

[0059] To allow for greater adjustment freedom in the top row of reinforcing bars, such as... Figure 8As shown, a fifth guide rail 63 is installed between the seventh support plate 62 and the eighth support plate 64, and the seventh support plate 62 moves along the fifth guide rail 63 under the drive of the cylinder 65.

[0060] To ensure accurate welding after positioning, such as Figure 8 As shown, the upper row limiting component 6 is also provided with a second welding gun 61. The second welding gun 61 is fixedly installed on the seventh support plate 62. The second welding gun 61 welds the weld points between the upper row of reinforcing bars 91 and the annular reinforcing bars 95.

[0064] In use, when a single planar welding is completed, the inner row limiting component 5 and the clamping component 4 release the welded annular steel bar 95. The upper row steel bar 91, the bottom row steel bar 92, the outer row steel bar 93, and the inner row steel bar 94 move linearly from the loading end to the loading end, and the welded annular steel bar 95 moves accordingly. After the inner row limiting component 5 and the clamping component 4 clamp the next annular steel bar 95, the gripper 49 and the clamping structure 58 move back and forth, using the toughness of the steel bar to expand the annular steel bar 95, so as to ensure that the upper row steel bar 91, the bottom row steel bar 92, the outer row steel bar 93, and the inner row steel bar 94 are accurately inserted into the appropriate position, avoiding mechanical failures caused by steel bar collisions due to inaccurate limiting. The gripper and the clamping structure then return to their original positions, ensuring the accuracy of the lap position.

[0065] Meanwhile, the internal adjustment and movement structures of positioning component 2, support component 3, clamping component 4, inner row limiting component 5, and upper row limiting component 6 ensure that when a single plane welding is completed, the upper row of reinforcing bars 91, bottom row of reinforcing bars 92, outer row of reinforcing bars 93, inner row of reinforcing bars 94, and ring reinforcing bars 95 each have sufficient degrees of freedom to fine-tune the structure, spacing, and size of the U-shaped reinforcing mesh 9. This ensures the dimensional requirements of the U-shaped reinforcing mesh 9 are met, allowing a single machine to position different sizes and models of U-shaped reinforcing mesh 9. This enables a single machine to produce different sizes and models of U-shaped reinforcing mesh 9 in a fully automated manner, improving product adaptability and achieving multi-purpose functionality to meet the needs of different environments. At the same time, users can flexibly adjust the size as needed, greatly reducing the user's procurement and production costs.
