Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically to a welding device for loading and unloading steel formwork for road and bridge construction. Background Technology
[0002] Road and bridge steel formwork is a steel formwork used for concrete pouring and forming in road and bridge engineering. It is made of high-strength steel, can withstand large loads, is not easily deformed, has a long service life, and can adapt to various complex road and bridge construction environments. The welding operations during the loading and unloading of road and bridge steel formwork mainly involve the welding of formwork lifting rings, lifting points, and reinforcement components, as well as the welding of formwork repair caused by collisions and wear during loading and unloading.

[0039] 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.
[0040] Please see Figures 1 to 5A welding device for loading and unloading steel formwork for road and bridge construction includes a welding base 1, a welding head 2 movably mounted on the welding base 1, a debris box 3, a support mesh plate 4, a transparent protective cover 5, protective components, a processing box 6, an adsorption component, an activated carbon mesh plate 7, and a molecular sieve 8. The debris box 3 is detachably connected to the welding base 1 and is located below the welding head 2. The support mesh plate 4 is detachably connected to the top of the debris box 3, which can stably place the steel formwork to be welded. Two transparent protective covers 5 are provided, which are movably mounted facing each other on the welding head 2. On both sides of the connector 2, protective components are positioned between two transparent protective covers 5. Sealing strips 19 are fixedly connected to the sides of the two transparent protective covers 5 that are close to each other. When the two transparent protective covers 5 are close together, the two sealing strips 19 can contact each other to ensure a sealed contact. This allows the two transparent protective covers 5 to provide sealing protection during the welding process of the road and bridge steel formwork. The processing box 6 is detachably connected to each transparent protective cover 5. Multiple mounting plates 22 are fixedly connected to the processing box 6, and each mounting plate 22 is threadedly connected to the transparent protective cover 5. The mounting screws 23 are connected between the mounting plate 22 and the transparent protective cover 5. Tightening the screws 23 allows for the installation and removal of the treatment box 6 on the transparent protective cover 5, thereby enabling the removal and replacement of the activated carbon mesh plate 7 and the molecular sieve 8. The treatment box 6 has an exhaust port for the release of filtered welding gases. Adsorption components are installed in each treatment box 6. The activated carbon mesh plate 7 is detachably mounted on one side of each adsorption component, and the molecular sieve 8 is detachably mounted on one side of each activated carbon mesh plate 7. The activated carbon mesh plate 7 is used in conjunction with a catalyst such as TiO2. It can adsorb and catalytically decompose VOCs and CO. The polar surface of molecular sieve 8 has a strong adsorption capacity for polar gases (such as HF and H2O). The pore size sieving effect can separate molecules of different sizes (such as 4A molecular sieve 8 with a pore size of 0.4nm, which can adsorb HF molecules with a diameter of 0.25nm). (When handling molecular sieve 8, acid and alkali resistant gloves should be worn to prevent skin contact). Thus, the gases generated when the steel template of the road and bridge are welded can be filtered and adsorbed through activated carbon mesh plate 7 and molecular sieve 8, reducing the impact of harmful substances in welding gases on the working environment and the health of workers.
[0041] refer to Figure 2 as well as Figure 4The protective assembly includes a connecting frame 9, a protective frame 11, and a drive block 12. The connecting frame 9 is detachably connected to one side of the welding base 1. Two connecting blocks 20 are symmetrically connected to the connecting frame 9. Both connecting blocks 20 are threadedly connected to the welding base 1 with connecting screws 21. By turning the connecting screws 21 between the welding base 1 and the connecting blocks 20, the connecting frame 9 can be installed and removed on the welding base 1. This allows for the installation and removal of the double-headed electric cylinder 10, the protective frame 11, and the transparent protective cover 5. The double-headed electric cylinder 10 is installed on the connecting frame 9. There are two protective frames 11, which are respectively connected between the double-headed electric cylinder 10 and the two transparent protective covers 5. The drive block 12 is fixedly connected to one side of each protective frame 11. The connecting frame 9 has a drive groove for the drive block 12 to slide, which allows the protective frame 11 to move stably on one side of the connecting frame 9.
[0042] When the double-headed electric cylinder 10 is started, it pushes the two protective frames 11 towards each other, which in turn causes the two protective frames 11 to move the two transparent protective covers 5 towards each other. The position of the two transparent protective covers 5 can be adjusted to adjust the protection range between them. This allows the two transparent protective covers 5 to protect the welding process of the road and bridge steel formwork, while the workers can observe the welding process through the transparent protective covers 5.
[0043] refer to Figure 3 The adsorption assembly includes a mounting base 13 and a suction fan 14. The mounting base 13 is located on the inner bottom wall of the processing box 6, and the suction fan 14 is mounted on the top of the mounting base 13. The output end of the suction fan 14 is connected through to the adjacent transparent protective cover 5.
[0044] After the two suction fans 14 are started, the welding gas inside the two transparent protective covers 5 can be adsorbed in all directions, so that the welding gas can be evenly introduced into the two treatment boxes 6. This allows the two activated carbon mesh plates 7 and the two molecular sieves 8 to evenly filter and adsorb the welding gas, reducing the impact of harmful substances in the welding gas on the working environment and the health of the workers.
[0045] refer to Figure 1 as well as Figure 5 The welding machine base 1 has a cavity for placing the chip box 3, which facilitates the installation and disassembly of the chip box 3 on the welding machine base 1. Multiple support rods 15 are fixedly connected to the inner bottom wall of the chip box 3. Multiple support grooves matching the support rods 15 are opened at the bottom end of the support mesh plate 4. Multiple support frames 16 are arranged in a rectangular array on the support mesh plate 4. Two handles 17 are fixedly connected between the multiple support frames 16.
[0046] When the support mesh plate 4 is placed in the debris box 3, multiple support rods 15 will enter multiple support slots respectively, which can stably support the support mesh plate 4 in the debris box 3, so as to provide stable support for the road and bridge steel formwork to be welded, thereby improving the stability of the road and bridge steel formwork welding. At the same time, the workers can move the support frame 16 by using the handle 17, and can move the support mesh plate 4 in the debris box 3, so that the support mesh plate 4 can be disassembled and cleaned, and the welding debris in the debris box 3 can be cleaned.
[0047] refer to Figure 3 Multiple fixing rods 18 are fixedly connected to the inner side wall of the processing box 6, and multiple fixing ports matching the fixing rods 18 are opened on the activated carbon mesh plate 7 and the molecular sieve 8.
[0048] By inserting multiple fixing ports on the activated carbon mesh plate 7 and molecular sieve 8 into multiple fixing rods 18, the activated carbon mesh plate 7 and molecular sieve 8 can be quickly installed in the processing box 6, and at the same time, the activated carbon mesh plate 7 and molecular sieve 8 can be quickly disassembled, replaced and cleaned.
[0049] In summary, after the steel template to be welded is placed on the support mesh plate 4, the double-headed electric cylinder 10 is started, bringing the two transparent protective covers 5 close together and the two sealing strips 19 into contact. Then, the welding head 2 welds the steel template. At the same time, the two suction fans 14 are started, so that the gas generated during welding is adsorbed into the two treatment boxes 6. The harmful substances in the welding gas are adsorbed and filtered by the two activated carbon mesh plates 7 and the two molecular sieves 8. The filtered welding gas is discharged through the exhaust port, thereby reducing the impact of harmful substances in the welding gas on the working environment and the health of workers.
