Description

Technical Field

[0001] This invention relates to the technical field of steel bar welding, and in particular to a rapid steel bar welding device for building construction. Background Technology

[0002] In the construction of reinforced concrete structures, steel bars are the main load-bearing components, and the reliable connection between them is crucial. In addition to mechanical connections, welding is a key process for achieving steel bar connections, and it is widely used in various scenarios such as beam-column joints, steel cage splicing, fixing of reserved and embedded parts, and correction of construction deviations.

[0003] Currently, construction sites still heavily rely on traditional manual arc welding for welding non-factory-prefabricated steel bars, especially those requiring temporary treatment. This process has several significant limitations in practical applications:

[0004] 1. Before welding, multiple assistants are needed to use tools to position and fix the steel bars. This is not only labor-intensive, but also inconvenient to operate in narrow or high-altitude work areas. The fixation stability is poor, and the steel bars are prone to displacement due to thermal stress or collision, which affects the final position accuracy and structural performance.

[0005] 2. When faced with a large number of fixed-end rebar connections with different tilt angles (vertical, horizontal or tilted), there is a lack of quick angle calibration and fixing tools. Positioning relies entirely on workers' experience, making it difficult to guarantee accuracy. At the same time, welders cannot always maintain the best welding posture, which easily leads to defects such as undercut and slag inclusion, resulting in unstable weld quality.

[0006] 3. When performing circumferential welds, welders need to frequently move their positions or have assistants rotate the reinforcing bars, which disrupts the welding continuity, easily leads to too many joints, reduces efficiency and quality, and may even prevent full welding when space is limited.

[0007] In summary, a significant amount of time is wasted on non-core processes such as positioning and fixing, resulting in low overall efficiency. Furthermore, welding quality relies excessively on the individual skills and sense of responsibility of welders, making it difficult to achieve stable and consistent high-quality connections, especially given the high turnover rate in the construction industry. Summary of the Invention

[0008] The purpose of this invention is to provide a rapid welding device for steel bars used in building construction, which aims to solve the problems in the prior art.

[0009] This invention is implemented as follows: a rapid welding device for steel bars used in building construction, comprising:

[0021] The end of the lifting adjustment rod passes through and extends to the outside of one side of the lifting frame;

[0022] The corresponding side walls of the upright frame and the lifting frame are respectively provided with an outer guide groove and an inner guide groove for the lifting adjustment rod to move.

[0028] A damping plate is disposed on the inner side of the friction belt and contacts the surface of the adjusting wheel to generate damping;

[0029] The switch adjustment rod is threadedly connected to the engagement plate, and a retaining plate is provided at its end. By turning the switch adjustment rod, the engagement plate can be driven to rotate around the axis, thereby pressing or releasing the friction belt to lock or release the adjustment wheel.

[0035] The second connecting plate is fixed to the bottom of the second clamping plate and is threadedly connected to the clamping rod;

[0036] When the clamping rod is rotated, the second connecting plate is driven by the threaded transmission to move the second clamping plate closer to or away from the first clamping plate, thereby forming a V-shaped or triangular clamping of the reinforcing bar.

[0037] Preferably, the support ring is provided with two sets of multiple supports evenly distributed along the axial direction in the Y direction, and each set of supports is provided with a telescopic rod, and the end of the telescopic rod facing the center is equipped with a guide wheel, and a first spring is sleeved on its outside;

[0038] The first spring provides radial elastic preload to the telescopic rod and guide wheel, enabling steel bars of different diameters to be positioned at the center of the support ring.

[0039] Preferably, one end of the telescopic rod located outside the support ring is connected to the body of the welding torch via a synchronous connecting piece;

[0040] The drive ring has evenly distributed paddles on one side surface. When the support ring rotates, the paddles periodically press down the welding gun's push switch to achieve automatic spot welding.

[0041] Preferably, the wire feeding mechanism includes:

[0042] The driving wheel and the driven wheel are disposed on the side wall of the support connected to the synchronous connecting piece, and are used to clamp and feed the welding wire;

[0043] The transmission gear is coaxially arranged with the drive wheel;

[0044] The inner wall of the drive ring is provided with annular toothed grooves. When the support ring rotates, the transmission gear meshes with the toothed grooves, thereby driving the drive wheel to rotate and realizing the synchronous feeding of welding wire.

[0048] The second spring is sleeved on the outside of the pull rod, with its two ends abutting against the mounting plate and the pressure plate, respectively.

[0049] The elastic force of the second spring ensures that the drive ring and toothed groove maintain elastic compression contact with the welding torch's push switch and transmission gear, thus ensuring the stability of power transmission.

[0050] The drive ring is disengaged from the welding torch and transmission gear by pulling the lever, thus completing the reset of the support ring.

[0051] The beneficial effects of the rapid welding equipment for steel bars used in building construction disclosed in this invention are:

[0052] 1. This solution replaces manual assistance in fixing by using the mechanical clamping of the fixture and the elastic positioning mechanism of the support ring, achieving rapid, accurate and automatic centering of the reinforcing bars. One person can perform the welding operation of the reinforcing bars, solving the problem of low positioning accuracy and efficiency caused by traditional reliance on manual assistance in fixing.

[0053] 2. This solution uses an angle adjustment component to enable the equipment to easily set and lock the welding angle, overcoming the difficulties in spatial angle adjustment and the problem of poor welding quality stability, and ensuring that the welding torch is always in the best welding posture.

[0054] 3. This solution achieves continuous ring welding through a drive ring-driven support ring rotation welding mechanism. Welders do not need to frequently change positions, solving the problem of inconvenience in ring weld welding and the need for frequent position changes.

[0075] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

In the description of this invention, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0077] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0078] In this embodiment:

[0079] Reference Figures 1-2 The diagram shows a preferred embodiment of the present invention.

[0080] This embodiment of a rapid welding device for steel bars used in building construction includes: a support frame 1;

[0081] The lifting plate 2 is movably mounted on the upright frame 1 via a linear drive mechanism and can move linearly along the X direction;

[0082] Angle adjustment component 21 is installed on the lifting plate 2;

[0083] The clamp 22 is installed at the output end of the angle adjustment component 21 and is used to clamp the movable end of the steel bar. No additional personnel are required to assist in fixing it. The angle adjustment component 21 can drive the clamp 22 to deflect along the Z direction to adjust the tilt angle of the fixed end of the steel bar.

[0084] The quick-welding assembly 3 is connected to the output end of the angle adjustment assembly 21 via the connecting seat 34 to synchronize its tilt angle;

[0085] The fast welding assembly 3 includes:

[0086] The support ring 32 is connected to the connecting seat 34 via a bearing. The inner ring of the support ring 32 is used to support the end of the fixed end steel bar and to position the free end steel bar so that the two are connected.

[0087] The welding torch 35 and the wire feeding mechanism 36 are arranged circumferentially through the inner side of the support ring 32 and facing the joint of the reinforcing bars;

[0088] The drive ring 33 is disposed on the connecting seat 34 and is used to drive the welding gun 35 and the wire feeding mechanism 36 to perform continuous circumferential welding when the support ring 32 rotates in the W direction.

[0089] exist Figure 3 In the linear drive mechanism, a lifting frame 11 is telescopically nested inside the upright frame 1. A locking rod 12 for locking the lifting frame 11 is threadedly connected to one end of the upright frame 1. The mechanism also includes a lifting adjustment rod 111 and a rotating rod 112 connected to the lifting frame 11 by a vertical bearing. A driving helical gear 113 and a transmission helical gear 114 are respectively sleeved between the two. The end of the lifting adjustment rod 111 extends through and to the outside of one side of the lifting frame 11. The corresponding side walls of the upright frame 1 and the lifting frame 11 are respectively provided with an outer guide groove and an inner guide groove for the lifting adjustment rod 111 to move. A first connecting plate 23 is fixed to the bottom of the lifting plate 2. The first connecting plate 23 passes through the outer guide groove and the inner guide groove and is threadedly connected to the rotating rod 112.

[0090] When the lifting adjustment rod 111 is rotated, the rotating rod 112 can be driven to rotate through the meshing transmission of the active helical gear 113 and the transmission helical gear 114. Since the first connecting plate 23 is threadedly connected to the rotating rod 112 and the first connecting plate 23 is limited by the outer guide groove and the inner guide groove, the rotating rod 112 will drive the first connecting plate 23 to move up and down along the direction of the outer guide groove and the inner guide groove when it rotates, thereby driving the lifting plate 2 to move up and down, so as to realize the adjustment of the overall height of the fixture 22 and the quick welding assembly 3.

[0091] Furthermore, the locking rod 12 can be tightened to lock the lifting frame 11 after the lifting frame 11 is adjusted to a suitable height, which can further increase the height of the clamp 22 and the quick welding assembly 3, and adapt to the steel bar welding needs of different heights at the construction site.

[0092] It is worth noting that, such as Figure 5 As shown, the angle adjustment assembly 21 includes: a support plate 217 vertically fixedly connected to the lifting plate 2; an adjusting wheel 212 mounted on the support plate 217 via bearings; a clamping plate 213 connected to one side of the support plate 217 via bearings, forming an openable clamping structure together with the support plate 217; a friction belt 215 surrounding the adjusting wheel 212, with its two ends fixed to the support plate 217 and the clamping plate 213 respectively; a damping sheet 216 disposed on the inner side of the friction belt 215, contacting the surface of the adjusting wheel 212 to generate damping; and a switch adjustment rod 214 threadedly connected to the clamping plate 213, with a locking plate at its end.

[0093] By turning the switch adjustment rod 214, the engagement plate 213 can be driven to rotate around the axis, thereby pressing or releasing the friction belt 215 to lock or release the adjustment wheel 212. The axis of the adjustment wheel 212 is fixed with a rotating shaft 211, which is connected to the lifting plate 2 through a bearing. The clamp 22 is connected to the end of the rotating shaft 211, and the connecting seat 34 of the quick welding assembly 3 is connected to the end of the rotating shaft 211 through the support arm 31. When the angle of the quick welding assembly 3 and the clamp 22 needs to be adjusted, it is only necessary to release the adjustment wheel 212 and turn the adjustment wheel 212 to lock it again. The operation is convenient and can realize the welding operation of fixed end steel bars with different tilt angles.

[0094] refer to Figure 4 The clamp 22 includes: a first clamping plate 221 and a second clamping plate 223; two clamping rods 222, which are arranged in parallel at the bottom of the first clamping plate 221 by bearings, and the two are synchronously rotated by a transmission belt 225; and a second connecting plate 224, which is fixed to the bottom of the second clamping plate 223 and threadedly connected to the clamping rods 222.

[0095] When the clamping rod 222 is rotated, the second connecting plate 224 is driven by the synchronous and threaded transmission of the transmission belt 225, causing the second clamping plate 223 to move closer to or away from the first clamping plate 221, thereby forming a V-shaped or triangular clamping of the reinforcing bar. This V-shaped or triangular clamping method can be flexibly adjusted according to the diameter and shape of the reinforcing bar, ensuring the stability of the reinforcing bar during welding and preventing shaking or displacement, thus guaranteeing the welding quality. Furthermore, the design of the clamp 22 also takes into account the convenience of operation. The movement of the second clamping plate 223 can be achieved by rotating the clamping rod 222, without complicated operation steps, thus improving work efficiency.

[0096] refer to Figure 6-9 As shown, the support ring 32 is provided with two sets of multiple supports 321 evenly distributed axially along the Y direction. Each set of supports 321 is provided with a telescopic rod 322. The end of the telescopic rod 322 facing the center is equipped with a guide wheel 323, and a first spring 324 is sleeved on its outside. The first spring 324 provides a continuous radial elastic preload to the telescopic rod 322 and the guide wheel 323, so that steel bars of different diameters can be positioned at the center of the support ring 32 during the rotation of the support ring 32. This ensures that the steel bars at the fixed end and the steel bars at the free end maintain precise coaxial connection, solves the drawback of relying on workers' experience for manual calibration in traditional welding, and ensures the alignment accuracy of the welded joint from the source. While ensuring welding accuracy, it always maintains the best welding posture, and is not prone to defects such as undercut and slag inclusion, resulting in more stable weld quality.

[0097] Furthermore, one end of one of the telescopic rods 322 located outside the support ring 32 is connected to the body of the welding torch 35 via a synchronous connecting piece 325. A set of levers 331 are evenly distributed on one side surface of the drive ring 33. When the support ring 32 rotates, the levers 331 periodically press down the push switch of the welding torch 35 to achieve automated pulse spot welding. The synchronous connecting piece 325 ensures that when the guide wheel 323 at the end of the telescopic rod 322 acts on the surface of steel bars of different diameters, the telescopic rod 322, through the linkage of the synchronous connecting piece 325, maintains an optimal and safe distance between the end of the welding torch 35 and the surface of the steel bar, preventing direct contact between the torch tip and the steel bar surface and causing damage. Simultaneously, it ensures the stability of the arc during welding, further improving welding quality. By utilizing the linkage of the mechanical structure, the positioning of the steel bar, the movement of the welding torch 35, and the triggering of the welding action are combined, achieving automation and precision in the welding process, reducing the difficulty and labor intensity of manual operation, and improving welding efficiency.

[0098] Furthermore, the wire feeding mechanism 36 includes a driving wheel 361 and a driven wheel 362, which are disposed on the side wall of the support 321 connected to the synchronous connecting piece 325 and move synchronously with the welding torch 35 to clamp and feed the welding wire; a transmission gear 363 is coaxially disposed with the driving wheel 361; the inner wall of the drive ring 33 is provided with an annular toothed groove 332, and when the support ring 32 rotates, the transmission gear 363 meshes with the toothed groove 332, thereby driving the driving wheel 361 to rotate and realizing the synchronous feeding of the welding wire.

[0099] It is worth noting that the wire feeding mechanism 36 utilizes the rotational motion of the support ring 32, and through the meshing of the transmission gear 363 with the toothed groove 332 on the inner wall of the drive ring 33, converts the rotational power into the power for feeding the welding wire. This not only simplifies the transmission structure but also improves the stability and accuracy of wire feeding. At the same time, the driven wheel 362 applies an elastic force to the driving wheel 361 through the spring shaft. The clamping action of the driving wheel 361 and the driven wheel 362 ensures that the welding wire will not slip or deviate during the feeding process, further guaranteeing the welding quality. In addition, the connection between the wire feeding mechanism 36 and the synchronous connecting piece 325 makes the entire welding equipment more compact in structure, facilitating operation and maintenance.

[0100] exist Figure 8 In this design, a mounting plate 333 is fixed to the bottom of the connecting seat 34; a pull rod 334 passes through the mounting plate 333, and its end is connected to the drive ring 33; a pressure plate 335 is fixed to the pull rod 334; a second spring 336 is sleeved on the outside of the pull rod 334, and its two ends abut against the mounting plate 333 and the pressure plate 335 respectively; through the elastic force of the second spring 336, the lever 331 and toothed groove 332 of the drive ring 33 maintain a reliable elastic pressing contact with the push switch of the welding torch 35 and the transmission gear 363, ensuring the stability of power transmission. This elastic pressing structure provides necessary buffering, reduces the impact and wear caused by rigid contact, and helps to extend the service life of related components. In addition, when it is necessary to reset the support ring 32 to replace the next set of steel bars to be welded, the operator only needs to pull the pull rod 334 outward to separate the drive ring 33 from the welding torch 35 switch and the transmission gear 363, thereby avoiding misoperation. This reset operation is simple and quick, improving the working efficiency and safety of the equipment.

[0101] This solution includes three sets of casters at the bottom of the support frame 1 for convenient and stable equipment transfer. One set of casters can be adjusted in height via threads for leveling on uneven construction sites. A horizontally expandable tray is also provided on one side of the bottom of the support frame 1 for placing a power supply and welding equipment. A horizontally expandable and retractable connecting bracket is also provided on one side of the bottom of the support frame 1 for connecting two sets of equipment for use when the steel bars to be welded are all movable ends.

[0102] This solution uses the upright frame 1 and its linear drive mechanism lifting frame 11, lifting adjustment rod 111, etc. to realize the vertical height adjustment of the lifting plate 2 and the entire welding execution unit; the angle adjustment component 21 drives the rotating shaft 211 to drive the clamp 22 to deflect synchronously with the fast welding component 3 through the cooperation of the friction belt 215 and the adjustment wheel 212 to adapt to the steel bars at different angles; the clamp 22 uses the clamping rod 222 to achieve V-shaped stable clamping of the fixed end steel bar; then, the free end steel bar is introduced into the center of the support ring 32 of the fast welding component 3, and the positioning mechanism composed of the telescopic rod 322 with the first spring 324 and the guide wheel 323 automatically centers; during welding, the support ring 32 rotates, and the drive ring 33 on it periodically triggers the welding gun 35 switch to perform spot welding through the toggle block 331, and at the same time, it meshes with the transmission gear 363 through the tooth groove 332 to drive the drive wheel 361 of the wire feeding mechanism 36 to feed wire synchronously, thereby completing the circumferential welding operation.

[0103] This solution replaces manual assistance in fixing by using the mechanical clamping of clamp 22 and the elastic positioning mechanism of support ring 32, achieving rapid, accurate and automatic centering of steel bars. One person can perform the welding operation of steel bars, solving the problem of low positioning accuracy and efficiency caused by traditional reliance on manual assistance in fixing.

[0104] This solution uses the angle adjustment component 21 to enable the equipment to easily set and lock the welding angle, overcoming the problems of difficult spatial angle adjustment and poor welding quality stability, and ensuring that the welding torch is always in the best welding posture.

[0105] This solution achieves continuous ring welding through the rotating welding mechanism of the support ring 32 driven by the drive ring 33. Welders do not need to frequently change positions, which solves the problem of inconvenience in welding ring seams and the need for frequent position changes. The whole process is highly mechanized and automated, replacing workers' positioning, fixing and skill welding, improving welding efficiency, and significantly reducing dependence on individual welder skills, thus ensuring the stability and uniformity of welding quality.

[0106] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
