Description

Technical Field

[0001] The utility model relates to the technical field of steel gratings, in particular to a feeding device for welding steel gratings. Background Art

[0002] Steel grating is an open steel plate, usually made by cutting multiple square or rectangular holes on the steel plate. It has high strength, good load-bearing and anti-slip properties, and can also provide ventilation, light transmission and rainwater drainage. Therefore, steel grating is widely used in many fields, such as construction, industry and transportation. According to the manufacturing process, it can be divided into press-welded steel grating and manual welded steel grating. According to the surface shape, it can be divided into toothed steel grating and flat steel grating. According to the material, it can be divided into hot-dip galvanized steel grating and stainless steel grating. According to the flat steel welding method, it can be divided into plug-in steel grating and composite steel grating. Steel grating has ventilation, lighting, heat dissipation, anti-slip, explosion-proof and other properties. The material is generally carbon steel, and the surface can be hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. In different industries and applications, the material, specification and shape requirements of steel grating may be different, and it needs to be selected and designed according to specific needs.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 The utility model provides a technical solution: a feeding device for steel grating welding, comprising: a workbench 1, a limit plate 2, a first motor 3, a first connecting shaft 4, a mounting hole 5, a first conveying wheel 6, a fastening bolt 7, a second connecting shaft 8, a second conveying wheel 9, a second motor 10, a conveying roller 11, a welding table 12, a welding frame 13, a welding assembly 14, a brush frame 15, a brush 16, a slag discharge hole 17 and a collection box 18.

[0029] When using the feeding device for welding steel grating, Figure 1 and Figure 2 As shown, the first connecting shaft 4 is rotatably connected to the workbench 1 through a connecting plate, and the first connecting shaft 4 is fixedly connected to the rotating shaft of the first motor 3, and the first motor 3 is fixedly installed on the upper side of the workbench 1. In addition, the first conveying wheel 6 is slidably connected to the outer side of the first connecting shaft 4. When the first conveying wheel 6 is not in use, the first conveying wheel 6 is all arranged behind the outer side of the first connecting shaft 4. When in use, the first conveying wheel 6 is moved as needed to adjust the spacing between the first conveying wheels 6 and the first conveying wheels 6. The side array of the first connecting shaft 4 is provided with mounting holes 5. In addition, the side of the first conveying wheel 6 is provided with a hole for connecting the fastening bolt 7 with the first conveying wheel 6 and the mounting hole 5. The fastening bolt 7 is screwed into the hole to fix the first conveying wheel 6 to the outer side of the first connecting shaft 4.

[0030] like Figure 1 , Figure 3 and Figure 4As shown, the second connecting shaft 8 is located directly above the first connecting shaft 4, and the second conveying wheels 9 are distributed in an array outside the second connecting shaft 8. The second connecting shaft 8 is fixedly installed on the upper side of the workbench 1 through a connecting plate. The position of the second conveying wheel 9 on the second connecting shaft 8 is adjusted so that the second conveying wheel 9 on the second connecting shaft 8 corresponds to the first conveying wheel 6 on the first connecting shaft 4 one by one. The first motor 3 is started, and the rotation of the first motor 3 will cause the first connecting shaft 4 to rotate. The rotation of the first connecting shaft 4 will temporarily cause the first conveying wheel 6 connected to the first connecting shaft 4 through the mounting hole 5 and the fastening bolt 7 to rotate together. When the first conveying wheel 6 rotates, the flat steel is inserted from the upper right side of the limiting plate 2, and the flat steel is located between the first conveying wheel 6 and the second conveying wheel 9. The limiting plate 2 supports the flat steel. Since the first conveying wheel 6 and the second conveying wheel 9 are vertically arranged in the middle, the flat steel will move horizontally to the left under the joint action of the second conveying wheel 9 during the conveying of the flat steel by the first conveying wheel 6. During the conveying of the flat steel, the second conveying wheel 9 will also rotate, thereby facilitating loading.

[0031] like Figure 5 and Figure 6 As shown, during the conveying to the left, the flat steel will contact with the brush 16, and the brush 16 will clean the impurities such as iron filings and dust on the surface of the flat steel. These cleaned impurities will fall under the action of gravity. In addition, a slag discharge hole 17 is provided inside the workbench 1, and the slag discharge hole 17 is located directly below the brush 16. These impurities will fall from the slag discharge hole 17 into the collection box 18, which is convenient for collecting impurities, thereby improving the firmness of welding. In addition, the brush 16 is snap-connected with the brush holder 15. After long-term use, the brush 16 will be worn. Move the brush 16 to the right and insert a new brush 16 from the right side of the brush holder 15. During the movement of the flat steel to the left, the brush 16 will not fall off from the brush holder 15.

[0032] like Figure 5 and Figure 6 As shown, the upper side of the welding table 12 is flush with the upper side of the limiting plate 2, which is convenient for the flat steel to move to the left to the welding assembly 14 on the lower side of the welding frame 13. During the welding process, the flat steel will not tilt. When the flat steel moves to the bottom of the welding assembly 14, the cross bar is placed on the upper side of the flat steel. The welding assembly 14 will weld the flat steel and the cross bar together, and start the second motor 10. After the first conveying wheel 6 and the second conveying wheel 9 convey the steel grating to the upper side of the conveying roller 11, the first conveying wheel 6, the second conveying wheel 9 and the conveying roller 11 convey the steel grating together. When the right end of the flat steel is no longer in contact with the first conveying wheel 6, the conveying roller 11 will continue to convey the steel grating.
