Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Embodiment: A welding device for use at a construction site of a building steel structure, such as Figure 1-Figure 10 As shown, it includes an installation body 1, a storage box 101 is fixedly installed at the lower end of the installation body 1, and the upper end of the storage box 101 is connected to the installation body 1, and the storage box 101 is provided to play a bearing role, and the upper end of the storage box 101 is provided with an opening; it is worth noting that the lower end of the storage box 101 is connected to a negative pressure device, so as to absorb the fume generated by welding during the welding process; a collection box 102 is inserted into the storage box 101, and the collection box 102 is provided to collect the welding slag generated during the welding process; it is worth noting that the bottom surface of the outer cover 2 is a mesh structure, which can bear the welding slag without affecting the absorption of the fume by the negative pressure device; Among them, the upper end of the installation body 1 is fixedly installed with an outer cover 2. By setting the outer cover 2, the weldment can be protected during the welding process, the strong light generated during welding can be avoided from affecting the workers, and the spattering of welding slag can be prevented; the inner wall of the outer cover 2 is symmetrically provided with multiple groups of grooves 201, and the inner wall of the groove 201 is provided with a deep groove 202, and the connection between the deep groove 202 and the groove 201 is smoothly connected. By setting the groove 201 and the deep groove 202, it can play a guiding and limiting role; the bottom surface of the groove 201 is provided with multiple groups of teeth 203, and by setting the teeth 203, it can mesh with other parts and play a driving role; the middle position of the outer cover 2 is provided with a welding module 3, and by setting the welding module 3, the butt joint of the weldment can be welded. It is worth mentioning that the welding module 3 is a prior art and can be rotated and moved to weld the butt joint of the weldment; and the upper end opening of the storage box 101 is arranged directly below the welding module 3 to facilitate the reception of welding slag during welding.

[0022] Among them, a moving block 4 is symmetrically arranged above the installation body 1, and the moving block 4 is an L-shaped structure. By setting the moving block 4, the weldment can be carried; a roller 401 is rotatably connected to the inside of one side of the short side of the moving block 4. By setting the roller 401, the friction between the weldment and the moving block 4 can be reduced, and the service life of the moving block 4 can be extended; a through opening 402 is opened on the long side of the moving block 4, which can play a guiding and storage role; a V-shaped opening 403 is opened at the end of the long side of the moving block 4, and the V-shaped opening 403 is opened to facilitate the subsequent support of the weldment and ensure the stability of the weldment; it is worth noting that there is enough space between the lower end of the moving block 4 and the upper surface of the installation body 1 for the extension of components.

[0023] Combined with Figure 1 -Attached Figure 7 , through two groups of symmetrically arranged clamping components 5 for clamping the weldment, the weldment can be quickly clamped and fixed between welding, ensuring stability during the welding process; the clamping component 5 includes a fixing bar 501 with one end movably connected to the inside of the moving block 4, and the other end of the fixing bar 501 is arranged inside the through opening 402. By setting the fixing bar 501, the weldment to be welded can be clamped and fixed; a through groove 502 is opened through the surface of the fixing bar 501, and the matching teeth 503 can play a limiting role; the inner wall of the through groove 502 is equidistantly provided with a plurality of groups of matching teeth 503. By opening the matching teeth 503, the fixing bar 501 is driven to move downward inside the through opening 402 and extend between the lower end of the moving block 4 and the upper surface of the installation body 1 through the matching teeth 503 with other parts, so as to realize the clamping and fixing of the weldment; Among them, the matching teeth 503 are meshedly connected with a gear ring 504, the gear ring 504 is arranged inside the through opening 402, and the gear ring 504 is rotatably connected to the inner wall of the through opening 402. By setting the gear ring 504, it can mesh with the matching teeth 503, thereby driving the fixed bar 501 to move downward; one end of the gear ring 504 is fixedly connected to a pulley group 505, and by setting the pulley group 505, the gear ring 504 can be driven to rotate; the other end of the pulley group 505 is connected to a gear rod 506 through a friction damping bearing. The gear rod 506 is a hollow structure, and one end of the gear rod 506 is rotatably connected to the surface of the moving block 4, the gear rod 506 is arranged inside the groove 201, and the gear rod 506 is meshed with the teeth 203. By setting the gear rod 506, it can be driven by the teeth 2 03 meshes, driving the pulley set 505 to rotate; it is worth mentioning that by setting up a friction damping bearing, it is possible to clamp weldments of different specifications; that is, when the moving block 4 drives the gear rod 506 to move inside the groove 201 and starts to mesh with the tooth 203, it will drive the pulley set 505 to rotate, and the pulley set 505 will drive the gear ring 504 to rotate synchronously and mesh with the matching tooth 503, so that the fixed bar 501 moves downward to clamp the weldment. If the weldment is clamped after the gear rod 506 is still inside the deep groove 202, then as the moving block 4 continues to move, the gear rod 506 will start to rotate alone, and will not drive the pulley set 505 to rotate, thereby clamping weldments of different specifications; the inner wall of the gear rod 506 is provided with a slope 5061.

[0024] Combined with Figure 4 -Attached Fig. 9 , a connecting piece 507 is provided inside the gear rod 506, and by providing the connecting piece 507, the gear rod 506 can drive the moving block 4 to rotate, so as to achieve the purpose of lifting the weldment; the connecting piece 507 includes a round rod 5071 inserted inside the gear rod 506, one end of the round rod 5071 is inserted into the cavity opened inside the moving block 4, one end of the round rod 5071 is slidably matched with the inner wall of the cavity through a slider, and the round rod 5071 is provided, and can be moved through it, so that the gear rod 506 can drive the moving block 4 to rotate synchronously; it is worth noting that one end of the round rod 5071 close to the groove 201 contacts and slidably matches with the inner wall of the groove 201, and the slider is a prior art and is not shown in the figure due to viewing angle problems; Among them, one end of the round rod 5071 is elastically connected to the inner wall of the cavity through a connecting spring 5072. By setting the connecting spring 5072, the reaction force generated by its deformation can drive the round rod 5071 to extend from the inside of the gear rod 506 and enter the inside of the deep groove 202 from the inside of the groove 201. It is worth mentioning that the connecting spring 5072 is in a stretched state in the initial state; the upper surface of the round rod 5071 is sleeved with a conical surface 5073, and the surface of the conical surface 5073 can fit with the surface of the inclined surface 5061. By setting the conical surface 5073, when the round rod 5071 extends into the interior of the deep groove 202, the conical surface 5073 will fit tightly with the inclined surface 5061, so that the moving block 4 and the gear rod 506 are connected, and then when the gear rod 506 continues to move, it can drive the moving block 4 to start rotating; it is worth mentioning that when the gear rod 506 moves inside the deep groove 202, it will only drive the pulley set 505 to rotate. When the gear rod 506 moves to correspond to the deep groove 202, it starts to drive the moving block 4 to rotate, and when it moves to the end of the deep groove 202, the moving block 4 will rotate from a state parallel to the installation body 1 to a state perpendicular to the installation body 1.

[0025] Combined with Figure 1 -Attached Fig.10 , and also includes two groups of symmetrically arranged support components 6 for supporting the weldment, which can lift the weldment upward and support it, so that the weldment can be quickly docked, reduce the phenomenon that the weldment is not stable enough during the welding process due to ground reasons, and ensure the welding quality and welding efficiency of the weldment; the support component 6 includes cross bars 601 symmetrically arranged on both sides of the moving block 4, and by setting the cross bars 601, it can start to rise with the rotation of the moving block 4; the surface of the cross bar 601 is penetrated by a guide groove 602, and the inner wall of the guide groove 602 is provided with a positioning hole 6021. By providing the guide groove 602, it can play a guiding and limiting role, so that the cross bar 601 will not fall, and by providing the positioning hole 6021, it can play a fixing role; Among them, a limiting rod 603 is provided inside the guide groove 602, and the limiting rod 603 is fixedly installed on the surface of the moving block 4. By setting the limiting rod 603, it can slide inside the guide groove 602, so that the moving block 4 can lift the cross bar 601 through the limiting rod 603 during the rotation process; the surface of the limiting rod 603 is elastically connected with a positioning rod 6031, and the positioning rod 6031 is plugged and matched with the positioning hole 6021. By setting the positioning rod 6031, after the rotation of the moving block 4 is completed, the positioning rod 6031 can be extended and entered into the interior of the positioning hole 6021 to fix the cross bar 601; the end of the cross bar 601 away from the moving block 4 is movably connected with a strip plate 604, and the strip plate 60 The upper surface of 4 is in the same horizontal plane as the upper surface of the moving block 4, and an arc-shaped notch is provided on the upper surface of the strip plate 604, and the arc-shaped notch is of the same depth as the V-shaped notch 403. By setting the strip plate 604 and providing the arc-shaped notch on its surface, when the moving block 4 rotates, the strip plate 604 can be driven to rise synchronously through the cross bar 601, so as to better support the weldment; it is worth mentioning that the position of the strip plate 604 can be set as needed, and can be away from or close to the position of the moving block 4; two groups of vertical rods 605 are symmetrically installed on the lower surface of the strip plate 604, and the lower ends of the two groups of vertical rods 605 are fixedly connected by the cross plate, and the strip plate 604 can be guided and limited by providing the vertical rods 605.

[0026] Specifically, when welding the weldment, first place the two groups of weldments between the two groups of moving blocks 4 and the fixed strip 501 respectively, then make the ends of the weldments contact the surface of the roller shaft 401, and push the weldments to drive the moving blocks 4 to move inside the outer cover 2, so that the gear rod 506 moves inside the deep groove 202 and meshes with the teeth 203, and then starts to drive the pulley set 505 to start rotating, and the rotating pulley set 505 will start to drive the gear ring 504 to rotate synchronously, and under the cooperation of the gear ring 504 and the matching teeth 503, drive the fixed strip 501 to move downward, so as to achieve the clamping and fixing of the weldment; After the weldment is clamped and fixed, and the weldment is continuously pushed, when the toothed rod 506 moves to the corresponding deep groove 202, the round rod 5071 will extend from the inside of the toothed rod 506 into the inside of the deep groove 202 under the reaction force generated by the deformed connecting spring 5072, and the conical surface 5073 will fit tightly with the inclined surface 5061, and then, with the cooperation of the toothed rod 506 and the teeth 203, the moving block 4 starts to rotate. While the moving block 4 rotates, the strip plate 604 fixedly connected to the cross bar 601 will be driven to rise synchronously through the cooperation of the limit rod 603 and the guide groove 602. When the moving block 4 rotates, it will drive the weldment and the fixed bar 501 to start rotating, ensuring that the weldment is always in a clamped state, and after the rotation of the moving block 4 is completed, the strip plate 604 will also rise to achieve support for the weldment, which not only ensures that the weldment can be quickly aligned, but also ensures welding accuracy and efficiency.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
