Description

Technical Field

[0001] The present invention relates to the technical field of positioning net production, and in particular to a device for automated production of special-shaped 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 special-shaped steel mesh: the welding of box girder positioning mesh is mostly carried out by manual welding. The manual welding of box girder mesh 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 and low efficiency; there are also hidden dangers in the safety of workers. In addition, because the finished welded 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 first transverse bars in the special-shaped steel mesh are different, the distances between several oblique bars are different, and the size required for the positioning mesh is different. The production and processing project needs to frequently replace the production mold, which increases the production cost.

[0007] In summary, there is an urgent need for a device for automated production of special-shaped positioning nets 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 the automated production of special-shaped positioning meshes, which is used to solve the problem that the welding of the existing box girder positioning meshes mentioned above is mostly carried out by manual welding.
