Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, it is a steel structure welding device for building construction. Background Technology

[0002] A steel structure welding device for building construction is a device used for welding steel structure building materials, such as waterstops and metal plates. It mainly consists of two parts: a clamp and a welding machine. It can be used to complete tasks such as... Figure 7 The diagram shows various welding methods.

[0003] Existing technology CN220971203U describes a steel structure welding device for building construction. It comprises a mounting base, connecting rod, screw, motor, movable block, connecting plate, plastic ring, movable strip, fixing nut, limiting plate, welding pipe, and welding head. Mounting bases are installed on both sides of the upper end of the worktable. A connecting rod is installed at the lower end of the mounting base, and a screw is installed at the upper end of the mounting base. A motor is installed on the left side of the screw. Movable blocks are installed on the outer sides of both the screw and connecting rod. A connecting plate is located at the lower rear end of the movable block, and a plastic ring is installed inside the connecting plate. A movable strip is installed at the upper end of the movable block, allowing the welding head to be aligned with the gap between two metal plates. When the motor is started, it drives the screw to rotate, allowing the movable block to move left and right outside the screw and connecting rod, thus performing welding work on the metal plates and improving welding efficiency.

[0004] The aforementioned equipment has certain shortcomings in welding steel structures. Steel structures can be welded in various ways, but this equipment can only perform horizontal welding. It cannot handle welding right-angle or obtuse-angle structures, nor can it be adjusted arbitrarily according to the welding angle, thus reducing its applicability. Secondly, when welding steel structures on both sides, the equipment requires reinstallation and fixation of the steel structure, and its inability to flexibly adjust the position of the welding device increases the difficulty of double-sided welding. Furthermore, the equipment lacks a misalignment adjustment structure, which can hinder its operation. Figure 7 In the lap welding operation shown in B, because the two sets of welding materials are fixed in the same plane, they cannot be staggered and therefore cannot be performed as shown in the diagram. Figure 7 The lap welding operation shown in B is shown in the figure. Summary of the Invention

[0005] The purpose of this invention is to provide a steel structure welding device for building construction, which can solve existing problems.

[0006] The problem solved by this invention is: 1. There are many different welding methods for steel structure materials. The above-mentioned equipment can only perform horizontal welding operations. It cannot meet the welding operations of steel structure materials with right angles and obtuse angles, and it cannot be arbitrarily adjusted according to the welding angle of the steel structure, which reduces its applicability. 2. Secondly, when performing double-sided welding of steel structure materials, the above-mentioned device needs to reinstall and fix the steel structure, and the position of the welding device cannot be flexibly adjusted, which increases the difficulty of the double-sided welding operation. 3. Furthermore, the aforementioned device lacks a misalignment adjustment structure; when it performs... Figure 7 In the lap welding operation shown in B, because the two sets of welding materials are fixed in the same plane, they cannot be staggered and therefore cannot be performed as shown in the diagram. Figure 7 The lap welding operation shown in B is shown in the figure.

[0007] The objective of this invention can be achieved through the following technical solutions: A steel structure welding device for building construction includes a first clamp, a second clamp, and a docking base. The first clamp is movably mounted on one side of the docking base, and the second clamp is movably mounted on the other side of the docking base. A welding seat is movably mounted on the front end of the docking base, and a welding machine is movably mounted on the outer surface of the welding seat. The docking base and the welding seat are movably connected by a flipper. The first clamp and the docking base are movably connected by two first rods, and the second clamp and the docking base are movably connected by two second rods. The two first rods and the two second rods are arranged side by side, and the second clamp and the two second rods are connected and fixed by an adjuster.

[0008] As a further technical solution of the present invention, the docking base is internally equipped with a first rotating rod and a second rotating rod for use with the first rod and the second rod. The first rotating rod is movably mounted on one side of the second rotating rod. The first rotating rod and the second rotating rod can synchronously drive the first rod and the second rod, causing the first rod and the second rod to drive the first clamp and the second clamp to rotate. After the first clamp and the second clamp complete the fixing operation of the steel structure materials, it can complete the connection between the two sets of steel structure materials. Figure 7 The auxiliary butt welding operations for types A, C, and D are shown.

[0009] As a further technical solution of the present invention, the first rotating rod and the second rotating rod are driven by gears. An elastic buckle for cooperating with the gears is installed on one side of the docking base. A rotating cap is fixedly installed on the outer surface of both ends of the first rotating rod. A docking sleeve is provided on the outer surface of both the first rotating rod and the second rotating rod. The user rotates the rotating cap, which drives the first rotating rod to rotate. The gears make the first rotating rod and the second rotating rod rotate synchronously, thereby making the first rotating rod and the second rotating rod drive the first clamp and the second clamp synchronously. The angle between the first clamp and the second clamp can be adjusted. The elastic buckle can be used to lock and fix the gear, which plays a fixing role for the first clamp and the second clamp.

[0010] As a further technical solution of the present invention, the upper ends of the first clamp and the second clamp are open structures, and a clamping plate is movably installed inside the first clamp and the second clamp. An adjusting cap for use with the clamping plate is movably installed in the middle of one side of the first clamp and the second clamp. A bolt is provided between the adjusting cap and the clamping plate. The user places the steel structure material to be welded inside the first clamp and the second clamp, and by rotating the adjusting cap, the adjusting cap drives the clamping plate to move using the bolt, so that the clamping plate presses and fixes the steel structure material in the first clamp and the second clamp.

[0011] As a further technical solution of the present invention, four lifting guide rods are provided between the first clamp and the pressure plate and between the second clamp and the pressure plate. The outer surfaces of the first clamp and the second clamp are fixedly installed with docking blocks. The setting of the four lifting guide rods can improve the stability of the pressure plate when it moves.

[0012] As a further technical solution of the present invention, a lifting slide is movably installed on the inner side of the adjuster. The adjuster and the second rod are movably connected through the lifting slide. The inner side of the lifting slide is provided with two sets of circular slots that cooperate with the second rod. When the user performs the B-type knot welding operation, the position of the second rod can be adjusted by using the adjuster in conjunction with the lifting slide, so that the two sets of steel structure materials are misaligned, allowing one set of steel structure materials to be placed on top of the other set of steel structure materials.

[0013] As a further technical solution of the present invention, the regulator and the lifting slide are movably connected by two limiting rods, and an adjusting bolt is provided between the middle of the regulator and the lifting slide. The user can drive the lifting slide to move up and down along the direction of the limiting rod by rotating the adjusting bolt and utilizing the threaded structure of the adjusting bolt.

[0014] As a further technical solution of the present invention, an arc-shaped buckle is fixedly installed on one side of the outer surface of the welding seat, and docking slots for use with the arc-shaped buckle are provided on both sides of the outer surface of the docking base. By using the two sets of docking slots in conjunction with the arc-shaped buckle, the welding seat can be fixed in both directions. When performing A-type or B-type welding operations, the welding seat can be flipped and adjusted using an adjuster, so that the welding seat can be installed arbitrarily on both sides of the docking base. Thus, double-sided welding of steel structure materials can be completed without disassembling the first clamp and the second clamp, thereby improving its structural strength.

[0015] As a further technical solution of the present invention, the flipper includes a rotating base plate and a side-rotating base plate. The rotating base plate is movably mounted on one side of the side-rotating base plate. The rotating base plate and the side-rotating base plate are movably connected by a second rotating shaft. When the welding seat is adjusted in position, the side-rotating base plate plate is first rotated by the first rotating shaft, causing the side-rotating base plate to rotate the welding seat 90 degrees, so that the welding seat and the docking base are perpendicular. Then, the rotating base plate plate plate is rotated by the first rotating shaft, so that the rotating base plate plate rotates the side-rotating base plate 180 degrees, thereby rotating the welding seat from one side of the docking base to the other side of the docking base. Then, the welding seat is fixed by using an arc-shaped buckle and a docking slot.

[0016] As a further technical solution of the present invention, the side-rotating substrate and the welding seat are fixedly connected by a docking clip, and the rotating substrate and the docking base are movably connected by a second rotating shaft.

[0017] The beneficial effects of this invention are: By setting a docking base, the steel structure welding device used in building construction, together with the first and second clamps, has a multi-angle welding adjustment structure, which can be arbitrarily adjusted according to the welding angle of the steel structure material, thus improving its applicability. During operation, the user places the steel structure material to be welded inside the first and second clamps. By rotating the adjusting cap, the adjusting cap drives the clamping plate to move via bolts, pressing and fixing the steel structure material within the first and second clamps. By rotating the rotating cap, the rotating cap drives the first rotating rod to rotate, and the gears cause the first and second rotating rods to rotate synchronously, thus synchronously driving the first and second clamps. The angle between the first and second clamps is adjusted, and the elastic buckle can be used to lock the fixed gear, fixing the first and second clamps. The first and second rotating rods synchronously drive the first and second rod bodies, causing them to rotate the first and second clamps. Finally, the butt joint position of the steel structure material is adjusted appropriately according to the weld position. After the first and second clamps have completed the fixing operation of the steel structure material, the two sets of steel structure materials can be joined together as follows: Figure 7The three fixing forms shown in A, C and D utilize the movement of the welding machine on the welding seat to complete the welding fixing operation in horizontal, right angle and obtuse angle positions. The first clamp and the second clamp play an auxiliary fixing role for the two sets of steel structure materials during the welding operation.

[0018] By incorporating a flipper, the use of the first and second clamps in the steel structure welding device for building construction can be optimized, giving it a flip-type auxiliary adjustment structure to facilitate operations such as... Figure 7 The double-sided welding operations shown in forms A and B enhance the weld strength. During use, when performing type A or type B welding operations, the adjusting device can be used to flip and adjust the welding seat, allowing it to be installed arbitrarily on both sides of the docking base. This enables double-sided welding of steel structure materials without disassembling the first and second clamps, thereby improving the structural strength. When adjusting the position of the welding seat, firstly, the first rotating shaft is used to rotate the side rotating base plate, causing the side rotating base plate to rotate the welding seat 90 degrees, making the welding seat and the docking base perpendicular. Then, the first rotating shaft is used to rotate the rotating base plate, causing the rotating base plate to rotate the side rotating base plate 180 degrees, thereby rotating the welding seat from one side of the docking base to the other side. Finally, the arc-shaped buckle and the docking slot are used to fix the welding seat, completing the position adjustment of the welding seat and the welding machine, enabling double-sided welding of the steel structure materials.

[0019] By setting an adjuster, when the steel structure welding device for building construction is used, it can adjust the misalignment between the two sets of steel structure materials during the B-type welding operation, so that it can complete the lap welding operation of the two sets of steel structure materials. During operation, the user rotates the adjusting bolt, which drives the lifting slide to move up and down along the limit rod using the threaded structure of the adjusting bolt. The lifting slide then drives the second rod, which in turn moves the second clamp. This causes the steel structure material installed on the second clamp to be misaligned with the steel structure material installed on the first clamp, allowing one set of steel structure material to be placed horizontally on top of the other set, preventing the two sets of steel structure material from bending and overlapping, thus enabling type B welding operations.

Detailed Implementation

[0023] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0024] like Figure 1-6 As shown, a steel structure welding device for building construction includes a first clamp 9, a second clamp 6, and a docking base 3. The first clamp 9 is movably installed on one side of the docking base 3, and the second clamp 6 is movably installed on the other side of the docking base 3. A welding seat 2 is movably installed at the front end of the docking base 3, and a welding machine 8 is movably installed on the outer surface of the welding seat 2. The docking base 3 and the welding seat 2 are movably connected by a flipper 24. The first clamp 9 and the docking base 3 are movably connected by two first rods 1, and the second clamp 6 and the docking base 3 are movably connected by two second rods 4. The two first rods 1 and the two second rods 4 are arranged side by side, and the second clamp 6 and the two second rods 4 are connected and fixed by an adjuster 7.

[0025] The docking base 3 has a first rotating rod 10 and a second rotating rod 11 movably installed inside, which work in conjunction with the first rod 1 and the second rod 4. The first rotating rod 10 is movably mounted on one side of the second rotating rod 11. The first rotating rod 10 and the second rotating rod 11 can synchronously drive the first rod 1 and the second rod 4, causing the first rod 1 and the second rod 4 to rotate the first clamp 9 and the second clamp 6. After the first clamp 9 and the second clamp 6 have completed the fixing operation of the steel structure materials, they can be used to fix the two sets of steel structure materials together. Figure 7 The auxiliary butt welding operations for types A, C, and D are shown.

[0026] The first rotating rod 10 and the second rotating rod 11 are driven by a gear 13. A spring-loaded buckle 12 that engages with the gear 13 is installed on one side of the docking base 3. Rotary caps 14 are fixedly installed on the outer surfaces of both ends of the first rotating rod 10. A docking sleeve 16 is provided on the outer surfaces of both the first rotating rod 10 and the second rotating rod 11. The user rotates the rotating caps 14, causing them to drive the first rotating rod 10 to rotate. The gear 13 then causes the first rotating rod 10 and the second rotating rod 11 to rotate synchronously, thereby synchronously driving the first clamp 9. The first clamp 9 and the second clamp 6 are used to adjust the angle between them. The elastic buckle 12 secures the gear 13, fixing the first clamp 9 and the second clamp 6. The elastic buckle 12 works by utilizing the movement of an internal slider in a special track. When the user presses the lever, the slider moves down the track and is forced to rotate a certain angle via an inclined plane. After release, the spring pushes the slider back, and due to the change in angle, the slider enters another track branch and is locked into a new stable position, achieving the first state switch (e.g., from popped up to retracted). Upon a second press, the slider moves down again and rotates in the opposite direction at the bottom. The spring causes it to return to the original track and stable point, restoring the state, thus completing the cycle of "press-switch-press again-return".

[0027] The upper ends of the first clamp 9 and the second clamp 6 are open structures, and a clamping plate 15 is movably installed inside the first clamp 9 and the second clamp 6. An adjusting cap 18 that works with the clamping plate 15 is movably installed on the middle of one side of the first clamp 9 and the second clamp 6. A bolt is provided between the adjusting cap 18 and the clamping plate 15. The user places the steel structure material to be welded inside the first clamp 9 and the second clamp 6, and rotates the adjusting cap 18 so that the adjusting cap 18 drives the clamping plate 15 to move using the bolt, so that the clamping plate 15 presses and fixes the steel structure material inside the first clamp 9 and the second clamp 6.

[0028] Four lifting guide rods 17 are provided between the first clamp 9 and the pressure plate 15, and between the second clamp 6 and the pressure plate 15. The outer surfaces of the first clamp 9 and the second clamp 6 are fixedly installed with docking blocks 5. The setting of the four lifting guide rods 17 can improve the stability of the pressure plate 15 when it moves.

[0029] The inner side of the adjuster 7 is movably installed with a lifting slide 19. The adjuster 7 and the second rod 4 are movably connected through the lifting slide 19. The inner side of the lifting slide 19 is provided with two sets of circular slots that are used in conjunction with the second rod 4. When the user performs the B-type knot welding operation, the position of the second rod 4 can be adjusted by using the adjuster 7 in conjunction with the lifting slide 19, so that the two sets of steel structure materials are staggered in height, so that one set of steel structure materials can be placed on top of the other set of steel structure materials.

[0030] The regulator 7 and the lifting slide 19 are movably connected by two limit rods 20, and an adjusting bolt 21 is provided between the middle of the regulator 7 and the lifting slide 19. The user can drive the lifting slide 19 to move up and down along the limit rods 20 by rotating the adjusting bolt 21 and utilizing the threaded structure of the adjusting bolt 21.

[0031] An arc-shaped buckle 22 is fixedly installed on one side of the outer surface of the welding seat 2. Both sides of the outer surface of the docking base 3 are provided with docking slots 23 that cooperate with the arc-shaped buckle 22. By using the two sets of docking slots 23 in conjunction with the arc-shaped buckle 22, the welding seat 2 can be fixed in both directions. When performing A-type or B-type welding operations, the welding seat 2 can be flipped and adjusted using the adjuster 7, so that the welding seat 2 can be installed arbitrarily on both sides of the docking base 3. Thus, double-sided welding of steel structure materials can be completed without disassembling the first clamp 9 and the second clamp 6, thereby improving its structural strength.

[0032] The flipper 24 includes a rotating base plate 25 and a side-rotating base plate 26. The rotating base plate 25 is movably mounted on one side of the side-rotating base plate 26. The rotating base plate 25 and the side-rotating base plate 26 are movably connected by a second rotating shaft 28. When the welding seat 2 is adjusted, the side-rotating base plate 26 is first rotated by the first rotating shaft 28, causing the side-rotating base plate 26 to rotate the welding seat 2 by 90 degrees, so that the welding seat 2 and the docking base 3 are perpendicular. Then, the rotating base plate 25 is rotated by the first rotating shaft 29, so that the rotating base plate 25 causes the side-rotating base plate 26 to rotate by 180 degrees, thereby rotating the welding seat 2 from one side of the docking base 3 to the other side of the docking base 3. Then, the arc-shaped buckle 22 is used in conjunction with the docking slot 23 to fix the welding seat 2.

[0033] When in use, by setting the docking base 3, the steel structure welding device for building construction, together with the first clamp 9 and the second clamp 6, has a multi-angle welding adjustment structure, which can be arbitrarily adjusted according to the welding angle of the steel structure material, thus improving its applicability. During operation, the user places the steel structure material to be welded inside the first clamp 9 and the second clamp 6. By rotating the adjusting cap 18, the adjusting cap 18 drives the clamping plate 15 to move via bolts, causing the clamping plate 15 to press and fix the steel structure material within the first clamp 9 and the second clamp 6. By rotating the rotating cap 14, the rotating cap 14 drives the first rotating rod 10 to rotate. The gear 13 causes the first rotating rod 10 and the second rotating rod 11 to rotate synchronously, thereby causing the first rotating rod 10 and the second rotating rod 11 to synchronously drive the first clamp 9 and the second clamp 6, adjusting... The angle between the first clamp 9 and the second clamp 6 is secured by the elastic buckle 12, which clamps the fixing gear 13, thus fixing the first clamp 9 and the second clamp 6. The first rotating rod 10 and the second rotating rod 11 can synchronously drive the first rod body 1 and the second rod body 4, causing the first rod body and the second rod body 4 to rotate the first clamp 9 and the second clamp 6. Finally, the butt joint position of the steel structure materials is appropriately adjusted according to the weld position. After the first clamp 9 and the second clamp 6 have completed the fixing operation of the steel structure materials, they can be used to complete the butt joint between the two sets of steel structure materials. Figure 7 The three fixing forms shown in A, C and D are achieved by using the welding machine 8 to move and weld on the welding seat 2, thereby completing the welding fixing operation in the horizontal, right angle and obtuse angle positions. The first clamp 9 and the second clamp 6 play an auxiliary fixing role for the two sets of steel structure materials during the welding operation. By setting the flipper 24, the use of the first clamp 9 and the second clamp 6 can be optimized when the steel structure welding device for building construction is used, giving it a flip-type auxiliary adjustment structure to facilitate its operation, such as... Figure 7 The double-sided welding operations shown in forms A and B enhance the weld strength. In use, when performing type A or type B welding operations, the adjusting device 7 can be used to flip and adjust the welding seat 2, allowing the welding seat 2 to be installed arbitrarily on both sides of the docking base 3. This allows for double-sided welding of the steel structure material without disassembling the first clamp 9 and the second clamp 6, thereby improving its structural strength. When adjusting the position of the welding seat 2, the first rotating shaft 28 is used to rotate the side rotating base plate 26, causing the side rotating base plate 26 to rotate the welding seat 2 by 90 degrees, making the welding seat 2 and the docking base 3 perpendicular. Then, the first rotating shaft 28 is used to rotate the rotating base plate 25, causing the rotating base plate 25 to rotate the side rotating base plate 26 by 180 degrees, thereby rotating the welding seat 2 from one side of the docking base 3 to the other side of the docking base 3. Then, the arc-shaped buckle 22 is used in conjunction with the docking slot 23 to fix the welding seat 2, completing the position adjustment of the welding seat 2 and the welding machine 8, enabling double-sided welding of the steel structure material. After the flip adjustment, the flip and rotation operation of the welding seat 2 is completed. The flipper 24 integrates the flip and rotation structure, so that the welding seat 2 can achieve mirror transfer. Therefore, in the double-sided welding process, as long as the position of the welding machine is adjusted in advance, the double-sided welding will not be affected by the thickness of the plate after the mirror adjustment.

[0034] By setting the regulator 7, when the steel structure welding device for building construction is used, it can adjust the misalignment between the two sets of steel structure materials during the B-type welding operation, so that it can complete the lap welding operation of the two sets of steel structure materials. During operation, the user rotates the adjusting bolt 21, which drives the lifting slide 19 to move up and down along the limiting rod 20 via the threaded structure of the adjusting bolt 21. The lifting slide 19 drives the second rod 4, which in turn drives the second clamp 6 to move. This causes the steel structure material installed on the second clamp 6 to be misaligned with the steel structure material installed on the first clamp 9, allowing one set of steel structure material to be placed horizontally on top of another set of steel structure material. This prevents the two sets of steel structure material from bending and overlapping, enabling B-type welding operations.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
