Description

Technical Field

[0001] This utility model relates to the field of steel grating welding technology, and in particular to an energy-saving welding device for steel grating. Background Technology

[0002] Steel grating is a metal grid structure component made of flat steel bars and crossbars arranged at certain intervals and fixed together by welding or press-locking. Its main characteristics are high strength, high load-bearing capacity, light weight, good drainage and ventilation performance, and anti-slip and self-cleaning functions. Steel grating is commonly used in industrial platforms, walkways, stair treads, drainage ditch covers, trestle bridges, and protective facilities for various equipment. Because its surface is usually hot-dip galvanized or otherwise anti-corrosion treated, it can be used outdoors or in harsh environments for a long time without easily rusting, thus extending its service life. Steel grating not only meets structural safety requirements but also balances economy and aesthetics, therefore it is widely used in construction, transportation, petrochemical, and power industries.

[0003] Steel grating, commonly used in industrial platforms, stair treads, and drainage covers, typically requires spot welding, gas shielded welding, or arc welding for mass production. However, existing steel grating welding equipment mainly relies on traditional welding tables or semi-automatic manual production lines, making it difficult to simultaneously weld multiple sets of intersecting steel plates. This results in low overall processing efficiency. Furthermore, existing equipment lacks an effective downward positioning structure during the welding and conveying of steel grating plates, failing to stably fix the intersecting plates to be welded. This easily leads to welding misalignment and insufficient dimensional accuracy. Therefore, in use, it generally suffers from poor welding consistency, low automation, and excessive reliance on manual adjustment of alignment and clamping, making it difficult to meet the demands for efficient, energy-saving, and mass production of steel grating.

[0004] Based on this, we propose an energy-saving welding device for steel grating to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an energy-saving welding device for steel gratings, which can solve the problems of existing steel grating welding equipment being unable to simultaneously weld multiple sets of steel plate intersections, lacking pressure positioning function, and relying too much on manual adjustment, resulting in low processing efficiency, poor welding quality, and insufficient automation.

[0007] To solve the above technical problems, this utility model provides an energy-saving welding device for steel grating, which adopts the following technical solution: it includes a steel plate conveying table, a steel grating body is placed inside one end of the steel plate conveying table, a welding mechanism is also provided in the middle of the steel plate conveying table, the welding mechanism includes an installation frame, welding components are installed on the outside of the installation frame, and two sets of first clamping components are connected in the middle of the installation frame. The welding assembly includes two sets of fuel storage tanks, which are respectively installed on the outer sides of the mounting frame. Two sets of guide grooves are provided on both sides of the inner wall of the mounting frame. Several sets of welding guns are provided in the middle of the mounting frame. Gas pipelines are also connected between the several sets of welding guns and the two sets of fuel storage tanks.

[0008] Optionally, the first clamping assembly includes a lifting frame, with guide sliders installed at both ends of the lifting frame. The guide sliders are matched with the guide groove structure, and the guide sliders and guide grooves are in sliding fit. The tops of both sets of guide sliders are connected to a first compression spring, and the bottom of the lifting frame is also rotatably connected to a lower pressure roller.

[0009] Optionally, the steel plate conveying platform has an embedded slot in the middle, which matches the mounting frame structure. Several sets of conveying rollers are provided inside both ends of the steel plate conveying platform, and second pressing components are provided on both sides of the inner wall of the steel plate conveying platform near the conveying rollers.

[0010] Optionally, the second pressing assembly includes a first lower pressure plate, with several sets of elastic adjustment members disposed on the outer side of the first lower pressure plate, and several sets of rollers evenly distributed on the inner side of the first lower pressure plate.

[0011] Optionally, the bottom of the first pressure plate near the roller is connected to multiple sets of second compression springs, and the bottoms of the multiple sets of second compression springs are connected by a second pressure plate.

[0012] Optionally, the elastic adjusting component includes a guide slide rod, which is interactively connected to the steel plate conveying table, and a third compression spring is also sleeved and connected to the outside of the guide slide rod.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. The steel grating welding device designed in this scheme, when the steel grating body is conveyed through the steel plate conveying table, uses a second clamping component installed on both sides of the inner wall of the steel plate conveying table. With the close cooperation of the first pressure plate, elastic adjusting component and roller, the two sides of the steel grating can be efficiently pressed down and fixed. When the steel grating body is conveyed to the bottom of the installation frame, the first clamping component plays a further role. The lifting frame drives the pressure roller to press down and fix the middle of the steel plate. The guide slider slides along the guide groove, and the first compression spring provides stable downward pressure. Through this double clamping mechanism, the deviation and shaking of the steel grating during the conveying and welding process can be effectively prevented, thereby improving the automation level of the device, reducing the frequency of manual intervention, and providing a stable guarantee for subsequent welding operations.

[0014] 2. The steel grating welding device designed in this scheme, through the installation of welding components on the outside of the frame, and with the synergistic effect of the fuel storage tank, welding gun, and gas supply pipeline, can achieve simultaneous welding of the intersections of crisscrossing steel plates. The fuel storage tank provides stable fuel for the welding gun, and the gas supply pipeline efficiently delivers gas to the gun head, enabling multiple welding guns to simultaneously weld multiple intersections. Through the above design, the processing cycle of a single piece can be effectively shortened, the overall production efficiency can be improved, energy-saving production can be achieved, the mass production needs of steel grating can be met, the optimization of automated welding processes can be promoted, and an efficient, energy-saving, and stable welding solution can be provided for the industrial field.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Refer to Figures 1 to 6 This utility model provides an embodiment of an energy-saving welding device for steel grating, including a steel plate conveying table 1. A steel grating body 2 is placed inside one end of the steel plate conveying table 1. A welding mechanism 3 is also provided in the middle of the steel plate conveying table 1. The welding mechanism 3 includes a mounting frame 4. Welding components 5 are installed on the outer side of the mounting frame 4. Two sets of first clamping components 6 are connected to the middle of the mounting frame 4. The welding components 5 include two sets of fuel storage tanks 7, which are respectively installed on both sides of the outer side of the mounting frame 4. Two sets of guide grooves 8 are provided on both sides of the inner wall of the mounting frame 4. Several... The dry welding guns 9 and several sets of welding guns 9 are connected to two sets of fuel storage tanks 7 by gas supply pipelines 10. This steel grating welding device, through the welding components 5 added to the outside of the mounting frame 4, can simultaneously weld the intersections of multiple sets of crisscrossing steel plates by cooperating with the fuel storage tanks 7, welding guns 9 and gas supply pipelines 10. This allows the plate to be processed at multiple welding points simultaneously in a single transmission process. This welding method can significantly improve the working efficiency of steel grating welding, shorten the single-piece welding processing cycle, reduce the number of manual interventions, and promote the improvement of welding automation level.

[0020] The first pressing assembly 6 includes a lifting frame 11, with guide sliders 12 installed at both ends of the lifting frame 11. The guide sliders 12 are structurally matched with the guide grooves 8, and the guide sliders 12 and the guide grooves 8 are in sliding fit. The tops of the two sets of guide sliders 12 are connected to the first compression springs 13. The bottom of the lifting frame 11 is also rotatably connected to the lower pressure rollers 14. Through the cooperation of the lifting frame 11, guide sliders 12, first compression springs 13, and lower pressure rollers 14, the first pressing assembly 6 can apply stable downward pressure to the middle of the steel grating body 2, achieving precise positioning and uniform force distribution of the plate during the welding process. This ensures that the steel grating body 2 does not shift or shake during the welding process, improving the dimensional accuracy of the weld and the overall welding consistency. The middle of the steel plate conveying table 1 is provided with an embedded slot 15, which is connected to the mounting frame 4. The steel plate conveying platform 1 is equipped with several sets of conveying rollers 16 at both ends. The inner walls of the steel plate conveying platform 1 near the conveying rollers 16 are also equipped with second pressing components 17. Through the structural design of the embedded slot 15 matching the mounting frame 4, the mounting frame 4, which is equipped with welding components 5 and first pressing components 6, can be limited and connected to the middle of the steel plate conveying platform 1. The second pressing component 17 includes a first lower pressure plate 18. Several sets of elastic adjustment components 19 are provided on the outer side of the first lower pressure plate 18. Several sets of rollers 20 are also evenly distributed on the inner side of the first lower pressure plate 18. The second pressing component 17 can apply a stable downward pressure to both sides of the steel grating body 2 being conveyed by transmission and conveying through the cooperation between the first lower pressure plate 18, the elastic adjustment components 19 and the rollers 20, so as to maintain the position of the plate and prevent shaking during the conveying process.

[0021] Multiple sets of second compression springs 21 are connected to the bottom of the first lower pressure plate 18 near the roller 20. Second lower pressure plates 22 are connected between the bottoms of these springs. By using the second compression springs 21 and the second lower pressure plates 22 installed inside the first lower pressure plate 18, the elastic buffering effect of the second compression springs 21 allows the clamping force to be evenly transmitted to the surface of the steel grating body 2, achieving stable and precise clamping and fixing of the plate. Simultaneously, it effectively absorbs vibrations generated during welding, reducing impact on the plate and equipment. The elastic adjustment component 19 includes guides. The guide slide 23 is interactively connected to the steel plate conveying table 1. A third compression spring 24 is also sleeved on the outside of the guide slide 23. The elastic adjustment component 19 can achieve elastic adjustment of the distance between the two sets of first lower pressure plates 18 through the cooperation between the guide slide 23 and the third compression spring 24, so as to adapt to steel grating bodies 2 of different widths. By using the adjusted distance, the two sets of first lower pressure plates 18 can effectively clamp and limit the two sides of the steel grating body 2, preventing it from shifting during the conveying and welding process, and ensuring accurate and stable welding.

[0022] Working Principle: The steel grating welding device designed in this scheme smoothly conveys the steel grating body 2 through the conveying rollers 16 inside the steel plate conveying table 1. It is further secured by second clamping components 17 installed on both sides of the inner wall of the steel plate conveying table 1. These second clamping components 17, through the cooperation of the first lower pressure plate 18, the elastic adjusting component 19, and the rollers 20, apply stable downward pressure to both sides of the conveyed steel grating body 2, maintaining the position of the plate during conveying and preventing swaying. This avoids plate misalignment affecting welding accuracy. When the steel grating body 2 is conveyed to the bottom of the mounting frame 4, the mounting frame 4... The first clamping assembly 6 installed on both sides inside can press down and fix the middle of the plate through the coordinated action of the hoisting frame 11, guide slider 12, first compression spring 13 and lower pressure roller 14. This ensures that the steel grating is stably stressed and maintains precise alignment during the welding process. Through the above-mentioned bidirectional clamping and fixing structure, not only is the position of the plate stable during the conveying and welding process, avoiding welding offset and weld size error, but it can also reduce the rework rate and material scrap rate, improve welding consistency, and provide a reliable mechanical foundation for subsequent automated welding, thereby achieving efficient, accurate and reliable plate conveying and positioning.

[0023] The steel grating welding device designed in this scheme, through the welding component 5 added to the outside of the mounting frame 4, and the cooperation between the fuel storage tank 7, welding gun 9 and gas pipeline 10, can simultaneously weld the intersections of multiple sets of crisscrossing steel plates. This allows for the simultaneous processing of multiple welding points during a single transfer of the plates. This welding method can significantly improve the efficiency of steel grating welding, shorten the single-piece welding cycle, reduce the number of manual interventions, and promote the improvement of welding automation. At the same time, the device utilizes centralized fuel supply and synchronous control of multiple sets of welding guns 9 to achieve efficient utilization of heat energy and energy saving, avoiding the energy waste of traditional welding equipment. Combined with the synergistic effect of the upper and lower bidirectional clamping structure, it can effectively improve weld consistency and plate dimensional accuracy, reduce welding defect rate, and ensure continuous stability of mass production. Thus, it achieves efficient, energy-saving, automated, and high-quality steel grating welding, providing reliable production assurance for steel grating applications such as industrial platforms, stair treads, and drainage covers.
