Description

Technical Field

[0001] The present invention relates to the technical field of positioning net production, and in particular to a device for automatically producing regular positioning nets. Background Art

[0002] With the in-depth development of economic construction, the use of positioning networks in the fields of construction, roads, bridges, and transportation has increased rapidly.

[0003] In the construction of railway prestressed box girders, the accuracy of the layout of the steel strands directly affects the construction quality of the box girders and the operational safety of the railway. Problems such as the looseness and non-straightness of the prestressed pipes for placing the steel strands will cause a lot of rework in the later construction, which will not only extend the construction period, increase the workload, but also waste manpower and material resources. Inaccurate positioning of the prestressed pipes will also cause prestress loss, which is extremely risky and harmful.

[0004] In traditional processes, the positioning of prestressed pipes generally adopts welding positioning of single positioning steel bars and steel cages. Single positioning steel bars are generally welded in the steel cage on site. The welding construction speed is slow and there are many welding points, which can easily cause technical problems such as inaccurate pipeline coordinate positioning. Therefore, the positioning net is designed to limit and fix the prestressed pipe, which is convenient for the penetration and installation of the prestressed pipe.

[0005] like Figure 1 As shown, it is a positioning mesh inside the box girder; it includes a special-shaped steel mesh welded by a first transverse reinforcement and an oblique reinforcement, and a regular steel mesh welded by a second transverse reinforcement, a third transverse reinforcement and vertical reinforcement of different lengths; its preparation method often adopts the method of separately producing and preparing the special-shaped steel mesh and the regular steel mesh, and then welding the two together to form a positioning mesh.

[0006] However, the following problems still exist in the existing processing of regular steel mesh: the welding of box girder positioning meshes is mostly carried out manually, and the manual welding of box girder meshes consumes a lot of manpower and time from the initial preparation of raw materials to the welding of the final finished product, resulting in high production costs, poor consistency and low efficiency; there are also hidden dangers in the safety of workers. In addition, since the finished welded products are manually welded, the welding error is relatively large, which reduces the yield rate; at the same time, due to the singleness of the mold, the distances between the second and third horizontal bars in the regular steel mesh are different, the distances between the vertical bars are different, and the lengths of the vertical bars, the second and third horizontal bars are different. The requirements for workers to cut the length of the steel bars one by one are high, the sizes required for the positioning mesh are different, the production and processing projects need to frequently change the welding processing parameters, and the production cost is high.

[0007] In summary, there is an urgent need for a device for automatically producing a regular positioning network to solve the above problems. Summary of the invention

[0008] In order to make up for the above shortcomings, the present invention provides a device for automatically producing regular positioning meshes, which is used to solve the above-mentioned problem that the welding of existing box girder positioning meshes is mostly carried out by manual welding.

In addition, because the welded finished product is manually welded, the welding error is relatively large, which reduces the yield rate; at the same time, due to the singleness of the mold, the distances between several second horizontal bars and third horizontal bars in the regular steel mesh are different, the distances between several vertical bars are different, and the lengths of several vertical bars, second horizontal bars and third horizontal bars are different.
