Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and in particular to an automated welding device for building construction. Background Art

[0002] In modern construction, rebar connections are a critical component of structural safety, and their welding quality and efficiency are directly linked to the stability and construction cycle of the entire project. Traditional manual welding methods are not only labor-intensive and inefficient, but also often struggle to ensure precise alignment and high-quality fusion of welded joints due to uncontrollable human factors, thus impacting the safety and durability of the entire structure.

[0003] Among them, electroslag pressure welding, as an efficient, energy-saving and environmentally friendly welding technology, has been widely used in the process of steel bar connection due to its unique welding mechanism and advantages. Electroslag pressure welding uses resistance heat and arc heat to form a molten pool at the steel bar connection and achieves a firm connection of the steel bars under pressure. It has the advantages of good welding quality, high production efficiency and easy operation.

[0004] However, in actual use, this traditional electroslag pressure welding device has the following technical problems: In actual use, before welding the two steel bars, the threaded rod is manually adjusted to fix the two steel bars. After the two steel bars are fixed, the operator needs to manually put the material box on the connection between the two steel bars. After welding, the operator needs to manually disassemble the material box, which is cumbersome and affects the welding efficiency. After welding is completed, the operator needs to take the collection box to collect and process the remaining solder. Since the existing electroslag pressure welding process places the collection box on one side of the material box for collection, it is easy for the solder to fall to the ground, resulting in waste.

[0005] In response to the above problems, the present invention document proposes an automated welding device for construction. Summary of the Invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automated welding device for construction that automatically adjusts the material storage barrel to the optimal position while fixing the steel bars, facilitating the direct delivery of solder without the need for manual disassembly of the material storage barrel, thereby greatly improving the convenience and welding efficiency of the operator.

[0010] Preferably, the diameter of the driving gear is smaller than the diameter of the driven gear, and the tooth plate is located on a side of the driving gear surface away from the two first rotation axes.

[0011] Preferably, a through hole for the steel bars to pass through is provided inside the storage barrel, and when the operator welds the two steel bars spliced ​​in the vertical direction, the connection point of the two steel bars is located inside the storage barrel.

[0017] Compared with the prior art, the present invention provides an automated welding device for construction, which has the following beneficial effects: 1. The automated welding device for construction is equipped with a welding frame and a material storage structure. When the operator needs to use the device to weld the steel bars, he first places the first mounting frame on the side of the bottom steel bar and adjusts the second electric push rod. When the second electric push rod is extended, the bottom steel bar is first limited and fixed by the fixing rod and the limit frame at the bottom. After the operator places another steel bar on the top of the bottom steel bar, the continuous movement of the second electric push rod makes the fixing rod and the limit frame at the top cooperate with each other to fix the top steel bar, automatically completing the splicing and fixation of the two steel bars, ensuring the fast and accurate docking and fixation of the two steel bars. At the same time, the unique tooth plate, active gear and driven gear linkage mechanism automatically adjusts the storage barrel to the optimal position while fixing the steel bar, which is convenient for direct delivery of solder and does not require manual disassembly and assembly of the storage barrel, greatly improving the convenience and welding efficiency of the operator.

[0018] 2. This automated welding device for construction incorporates a collection mechanism, enabling the automated collection and reuse of residual welding material. After the rebar is welded and the solder solidifies, the second electric push rod is adjusted to automatically release the rebar. Simultaneously, the drive frame, utilizing the precise coordination of the toothed plate and gears, rotates and opens the storage barrel, cleverly directing unused solder completely into two storage hoods and smoothly discharging it through the guide tube. This process not only simplifies post-weld cleanup and improves operational efficiency, but more importantly, maximizes solder recycling and reduces resource waste.

[0019] 3. The automated welding device for construction is provided with an adjustment component and a fixing component. When the operator needs to weld the steel bars, the second electric push rod is extended and the fixing rod at the bottom is squeezed first, thereby automatically fixing the steel bars at the bottom. As the second electric push rod continues to extend, the fixing rod at the top is squeezed, thereby limiting and fixing the steel bars at the top. By automatically limiting and fixing the two steel bars, the operator's welding efficiency is improved. At the same time, since the two steel bars are limited and fixed in turn, the operator is provided with sufficient space and convenience, allowing him to accurately connect the top steel bars with both hands, thereby ensuring the accuracy of the steel bar splicing and the firmness of the subsequent welding quality.

A through hole for the steel bar 9 to pass through is provided inside the storage barrel 403, and when the operator welds the two steel bars 9 spliced ​​in the vertical direction, the connection between the two steel bars 9 is located inside the storage barrel 403.

[0034] In the present invention, the collecting structure 7 includes two second mounting covers 701 fixedly connected to the side surfaces of the first mounting frame 101, the second mounting cover 701 is rotatably connected to the second rotating shaft 702, the outer wall of the second rotating shaft 702 is fixedly connected to the material storage cover 703, the two material storage covers 703 can rotate around the second rotating shaft 702 to a fitting state, the material storage cover 703 is provided with a through hole for the steel bar 9 to pass through, and the bottom of one of the material storage covers 703 is connected to a material guide pipe 704, the outer wall of the second rotating shaft 702 is fixedly connected to a mounting plate 705, the top of the mounting plate 705 is fixedly connected to a torsion spring 706, the end of the torsion spring 706 away from the mounting plate 705 is fixedly connected to the second mounting cover 701, the torsion spring 706 is sleeved on the outer wall of the second rotating shaft 702, the outer wall of the material storage barrel 403 is fixedly connected to a push plate 8, and the height of the bottom of the push plate 8 is lower than the material storage cover 703. The height of the top, when the two material storage barrels 403 are rotated to open, the material storage cover 703 can be driven to rotate by the push plate 8. By setting the collecting structure 7 and the push plate 8, after the operator welds the two steel bars 9 in the vertical direction through the welding frame 1 and the welding power supply assembly 2, after the solder at the connection between the two steel bars 9 solidifies, the operator adjusts the second electric push rod 301 to make the second electric push rod 301 contract, so that the fixing rod 501 automatically releases the limit fixation on the steel bar 9. At this time, the driving frame 6 drives the two material storage barrels 403 to rotate and open through the tooth plate 406. When the material storage barrels 403 are opened to a certain extent, the remaining solder inside them automatically falls down into the two material storage covers 703, and then is discharged through the material guide pipe 704, so that the operator can collect the solder that has not participated in the welding process, so as to facilitate subsequent reuse.

[0035] Working principle: When the operator needs to use the device to weld the steel bar 9, first place the first mounting frame 101 on the side of the bottom steel bar 9, adjust the second electric push rod 301, and when the second electric push rod 301 is extended, the extrusion block 302 and the extrusion plate 303 first squeeze the fixing rod 501 on the side of the first mounting frame 101, and the fixing rod 501 and the limiting frame 106 on the side of the first mounting frame 101 cooperate with each other to limit and fix the bottom steel bar 9. After the operator places another steel bar 9 on top of the bottom steel bar 9, as the second electric push rod 301 continues to move, the fixing rod 501 and the limiting frame 106 on the side of the second mounting frame 102 cooperate with each other to fix the top steel bar 9, and automatically complete the splicing and fixation of the two steel bars 9; When the fixed rod 501 at the top moves, it drives the driving frame 6 to move through the mounting sleeve 503, so that the tooth plate 406 drives the driving gear 405 to rotate, and with the cooperation of the two driven gears 404, the two storage barrels 403 automatically rotate to a tightly fitted state, at this time ensuring that the connection between the two steel bars 9 is inside the two storage barrels 403, the operator directly pours the solder into the two storage barrels 403, and then clamps the welding power supply assembly 2 to the outer wall of any one of the steel bars 9, and supplies power to the steel bars 9, so that the connection between the two steel bars 9 is melted, and the solder inside the storage barrel 403 is also melted, at this time the first electric push rod 105 contracts, so that the end face of the top steel bar 9 contacts the end face of the bottom steel bar 9, and when the steel bar 9 and the melted solder solidify, the welding process is completed; The operator then adjusts the second electric push rod 301 to retract the second electric push rod 301, and the second electric push rod 301 drives the extrusion block 302 and the extrusion plate 303 to move downward. Under the action of the reset spring 504, the fixing rod 501 automatically drives the installation sleeve 503 to retract into the sleeve 502, so that the fixing rod 501 automatically releases the limit fixation on the steel bar 9. At this time, the driving frame 6 drives the two storage barrels 403 to rotate and open through the tooth plate 406. When the storage barrel 4 03 is opened to a certain extent, the remaining solder inside it automatically falls down into the two storage covers 703, and is then discharged through the guide tube 704, so that the operator can collect the solder that has not participated in the welding process, so that it can be reused later. When the two storage barrels 403 continue to rotate and open to a certain extent, the pushing plate 8 fixed on the side of the storage barrel 403 contacts the storage cover 703, thereby pushing the storage cover 703 to rotate, so that the two storage covers 703 automatically complete the rotation and opening movement.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
