Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a windbreak device for welding steel trusses. Background Technology

[0002] Steel trusses are structural forms made of steel and are widely used in buildings, bridges, and other engineering projects. They are lightweight, have high load-bearing capacity, and short construction cycles, making them suitable for large-span and high-strength building applications. They are commonly found in large-scale projects such as stadiums, exhibition centers, and industrial plants. Due to their excellent performance and flexible design, steel trusses have become an indispensable structural form in modern architecture.

[0003] Its basic structure is composed of a series of triangular units. This design can effectively distribute and bear external loads, improving the stability and strength of the structure.

[0004] However, steel truss welding has certain requirements on the wind speed of the welding environment. In environments with high wind speeds, the welding speed may decrease, requiring more time for adjustment and processing, which greatly reduces work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a windbreak device for welding steel trusses, which aims to improve the existing technology where the welding environment for steel trusses has certain requirements for wind speed. In environments with high wind speeds, the welding speed may decrease, requiring more time for adjustment and processing, thus greatly reducing work efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a windbreak device for welding steel trusses, comprising a steel truss, with a first mounting plate and a second mounting plate disposed on the outside of the steel truss. Movable grooves are formed on both sides of the first and second mounting plates, and movable plates are slidably connected inside the movable grooves. A tie rod is fixedly connected inside the movable plate, and a spring is disposed on the outside of each tie rod. One end of the spring is fixedly connected to the outside of the movable plate, and the other end of the spring is fixedly connected to the inside of the movable groove. A limit block is fixedly connected to one end of the tie rod, and a handle is fixedly connected to the outside of the limit block. Windbreak components are disposed on the inner sides of both the first and second mounting plates, and the windbreak components are used for windbreak.

[0007] Furthermore, the windbreak assembly includes windbreak plates, all of which are disposed inside the mounting slots. The first mounting plate and the second mounting plate have mounting slots inside. Mounting holes are provided inside both sides of the windbreak plates, and pull rods are provided inside the mounting holes.

[0008] Furthermore, a first movable wheel is fixedly connected to the inner top of the first mounting plate and the second mounting plate, and a second movable wheel is fixedly connected to the inner side of the first mounting plate and the second mounting plate.

[0009] Furthermore, a limiting plate is fixedly connected to one end of the first mounting plate.

[0010] Furthermore, a limiting groove is formed inside the second mounting plate, and a limiting plate is slidably connected inside the limiting groove.

[0011] Furthermore, a cylinder is fixedly connected to one side of the second mounting plate, and a limit plate is fixedly connected to the output end of the cylinder.

[0012] Furthermore, the exterior of both the first and second movable wheels is located on the exterior of the steel truss.

[0013] Furthermore, columns are fixedly connected to both sides of the steel truss.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by pulling the handle, the limiting block and the pull rod are moved. While the pull rod moves, the wind deflector is installed inside the mounting slot. At the same time, the movement of the pull rod causes the movable plate to compress the spring. When the wind deflector is installed in the mounting slot inside the mounting plate, the handle is released, and the spring force limits the pull rod in the mounting hole inside the wind deflector. When disassembly is required, the handle can be pulled. The detachable wind deflector makes maintenance and cleaning easier. During the welding process, welding slag, oil stains and other debris may accumulate. Regularly disassembling the wind deflector for cleaning can ensure the normal operation of the device and the stability of the welding process.

[0016] 2. In this utility model, the limit plate and the first mounting plate are moved by the driving cylinder. The width of the two sets of mounting plates is adjusted by the width of the steel truss. The movement of the two sets of mounting plates drives the movement of two sets of moving wheels. The flexible and adjustable windproof device can not only meet the welding requirements of different steel trusses and improve welding quality and safety, but also improve work efficiency and reduce costs. The effective windproof device reduces losses during the welding process, reduces rework and material waste caused by defects, and reduces the overall construction cost. The setting of moving wheels improves the practicality of the windproof device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a windbreak device for welding steel trusses, comprising a steel truss 1, with a first mounting plate 10 and a second mounting plate 12 disposed on the outside of the steel truss 1. Movable grooves 3 are formed on both sides of the first mounting plate 10 and the second mounting plate 12, for mounting movable plates 7 and springs 6. Movable plates 7 are slidably connected inside the movable grooves 3, and tie rods 11 are fixedly connected inside the movable plates 7. Springs 6 are disposed on the outside of the tie rods 11, with one end of the springs 6 fixedly connected to the outside of the movable plates 7 and the other end fixedly connected to the inside of the movable grooves 3. A limit block 4 is fixedly connected to one end of the tie rod 11. The external fixed connection of 4 is a handle 5. The handle 5 drives the limit block 4 to move, and the limit block 4 drives the pull rod 11 to move. When the pull rod 11 moves, it drives the movable plate 7 to compress the spring 6. The inner sides of the first mounting plate 10 and the second mounting plate 12 are provided with windproof components. The windproof components are used to block the wind. The windproof components include windproof plates 17. The windproof plates 17 are all set inside the mounting slots 16. The windproof plates 17 are limited by the mounting holes 18 and the pull rod 11. The first mounting plate 10 and the second mounting plate 12 have mounting slots 16 inside. The windproof plates 17 have mounting holes 18 inside both sides. The pull rod 11 is set inside the mounting holes 18.

[0025] When installing the wind deflector 17, pull the handle 5 to move the limiting block 4 and the pull rod 11. As the pull rod 11 moves, the wind deflector 17 is installed inside the mounting slot 16. As the pull rod 11 moves, it causes the movable plate 7 to compress the spring 6. When the wind deflector 17 is installed in the mounting slot 16 inside the mounting plate, release the handle 5. The spring force of the spring 6 limits the pull rod 11 in the mounting hole 18 inside the wind deflector 17. When disassembly is required, pull the handle 5 and repeat the above operation. The detachable wind deflector 17 makes maintenance and cleaning easier. During the welding process, welding slag, oil stains and other debris may accumulate. Regularly disassembling the wind deflector 17 for cleaning can ensure the normal operation of the device and the stability of the welding process.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The first mounting plate 10 and the second mounting plate 12 are fixedly connected to the inner top of the first moving wheel 8 and the second mounting plate 12 are fixedly connected to the inner side of the first mounting plate 10 and the second mounting plate 12. The first moving wheel 8 is a brake caster and contacts the upper end face of the steel truss 1. The second moving wheel 9 is a guide wheel and contacts the side of the steel truss 1. One end of the first mounting plate 10 is fixedly connected to a limit plate 13. The second mounting plate 12 has a limit groove 14 inside. The limit groove 14 cooperates with the limit plate 13 to limit the first mounting plate 10. The limit plate 13 is slidably connected inside the limit groove 14. A cylinder 15 is fixedly connected to one side of the second mounting plate 12. The output end of the cylinder 15 is fixedly connected to the limit plate 13. The outer sides of the first moving wheel 8 and the second moving wheel 9 are both set outside the steel truss 1. Columns 2 are fixedly connected to both sides of the steel truss 1.

[0027] When the windbreak device is placed, the driving cylinder 15 drives the limiting plate 13 and the first mounting plate 10 to extend and move. The width of the two sets of mounting plates is adjusted by the width of the steel truss 1. The movement of the two sets of mounting plates drives the movement of the two sets of moving wheels. The flexible and adjustable windbreak device can not only meet the welding requirements of different steel trusses 1, improve welding quality and safety, but also improve work efficiency and reduce costs. By effectively reducing losses during the welding process, the windbreak device can reduce rework and material waste caused by defects, thereby reducing the overall construction cost. The setting of multiple sets of moving wheels improves the practicality of the windbreak device. The two sets of moving wheels ensure that the device will not deflect or shake during the movement along the steel truss 1, ensuring the stability of the device.

[0028] Working principle: When installing the wind deflector 17, pulling the handle 5 moves the limiting block 4 and the pull rod 11. As the pull rod 11 moves, the wind deflector 17 is installed inside the mounting slot 16. Simultaneously, the pull rod 11 moves, causing the movable plate 7 to compress the spring 6. When the wind deflector 17 is installed in the mounting slot 16 within the mounting plate, releasing the handle 5 allows the spring 6 to limit the pull rod 11 within the mounting hole 18 inside the wind deflector 17. To disassemble, simply pull the handle 5 and repeat the above operation. The detachable wind deflector 17 simplifies maintenance and cleaning. During welding, welding slag, oil, and other debris may accumulate; periodically disassembling the wind deflector 17 for cleaning is recommended. To ensure the normal operation of the device and the stability of the welding process, when the windbreak device is placed, the limit plate 13 and the first mounting plate 10 are extended and moved by the drive cylinder 15. The width of the two sets of mounting plates is adjusted by the width of the steel truss 1. The movement of the two sets of mounting plates drives the movement of the two sets of moving wheels. The flexible and adjustable windbreak device can not only meet the welding requirements of different steel trusses 1, improve welding quality and safety, but also improve work efficiency and reduce costs. By effectively reducing losses in the welding process through the windbreak device, rework and material waste caused by defects can be reduced, thereby reducing the overall construction cost. The use of multiple sets of moving wheels improves the practicality of the windbreak device.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
