Description

Technical Field

[0001] The present invention relates to the technical field of spiral stirrup welding, and particularly relates to a welding device and method for processing spiral stirrups. Background Art

[0002] Spiral stirrups are stirrups arranged continuously in a spiral shape along the height direction of a column. They are generally made of round steel or ribbed steel bars and are formed into a continuous spiral shape through mechanical bending. Compared with ordinary rectangular stirrups, spiral stirrups are continuous and can uniformly restrain the core part of concrete. Their pitch (the vertical distance between two adjacent turns of spiral stirrups) and diameter can be adjusted according to design requirements to adapt to different member sizes and force requirements. When the member is under compression, the concrete will produce lateral expansion deformation. Spiral stirrups can effectively restrain this lateral deformation, making the concrete in a triaxial compression state. Under the triaxial compression state, the compressive strength and deformation ability of the concrete will be significantly improved.

[0003] In the prior art, spiral stirrups and several groups of main reinforcement bars arranged in a circumferential array are fixed by welding to form a steel cage structure; In the actual application process, after the spiral stirrups are bent and formed, the formed spiral stirrups are unfolded from one end, slowly sleeved along the axial direction of the main reinforcement bars, and the position of the spiral stirrups is adjusted after sleeving to make them closely fit with the main reinforcement bars. Since the spiral stirrups have a certain elasticity, when sleeved for a certain distance, binding wires need to be used for temporary fixation to prevent the spiral stirrups from resetting, and the whole process is rather cumbersome.

[0015] The present invention provides a welding device and method for spiral stirrup processing, including the following beneficial effects: 1) The present invention positions each main reinforcement steel bar of the main reinforcement structure by means of a positioning module, and does not need to use a reinforcement hoop to pre-position and weld the main reinforcement steel bars, which not only improves efficiency but also reduces labor costs. The positioned main reinforcement structure can be directly transported to the sleeve end by means of a conveying module, and the round steel bar is spirally sleeved on the main reinforcement structure by means of the sleeve module to form a spiral hoop. The present invention also does not need to pre-process the spiral hoop, and the spiral hoop can be directly bent and formed on the main reinforcement structure, further improving the forming efficiency of the steel cage structure. After the spiral hoop is formed on the main reinforcement structure, the spiral hoop and the main reinforcement steel bar of the main reinforcement structure can be directly spot-welded and fixed by a welding manipulator, so that the welding efficiency of the two is greatly improved. At the same time, the present invention sleeves the spiral hoop and welds the main reinforcement structure in sections, so as to avoid the phenomenon of the spiral hoop shrinking under the action of elastic force, and has higher stability. 2) In the initial state of the present invention, each main reinforcement steel bar is also correspondingly embedded in the positioning groove on the second arc-shaped positioning plate. Since the positioning module is located at the sleeve end in the present invention, after the main reinforcement steel bar is embedded, the first section of the plain round steel bar can be directly bent and formed on the main reinforcement structure through the sleeve module to form the first section of the spiral hoop reinforcement. During the bending and forming process of the plain round steel bar on the main reinforcement structure, a large torsional force will be applied to the main reinforcement steel bar. The second arc-shaped positioning plate provided in the present invention can provide a supporting force to each main reinforcement steel bar during the forming process, thereby preventing the main reinforcement steel bar from being subjected to force and gathering toward the axial direction, thereby improving the stability of the bending and forming; 3) The present invention sets two groups of connection parts connected to the positioning ring on the first limit frame and the second limit frame. When the rotating mechanism drives the main reinforcement structure to rotate, as the main reinforcement steel bars rotate to the connection parts located on the upper side, the connection parts can be automatically opened to make the upper connecting plate and the upper positioning plate in a disconnected state, while the connection parts between the lower connecting plate and the lower positioning plate are still in a connected state, so that the limit frame is still in a state of positioning support for the positioning ring. When the main reinforcement steel bars rotate to between the two groups of connection parts, the connection parts on the upper side are reset to reconnect the upper connecting plate and the upper positioning plate. As the rotating mechanism continues to rotate, the connection parts on the lower side are disconnected to avoid interference between the main reinforcement steel bars and the connection parts.

[0018] The following is a detailed description of the specific embodiments of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0019] Embodiment 1 As Figures 1 to 3 shown, a welding device for processing spiral stirrups provided in an embodiment of the present invention includes a conveying module 2 and a positioning module 3 for positioning and fixing the main reinforcement structure 1; In this embodiment, the main reinforcement structure 1 is formed by enclosing a plurality of groups of main reinforcement bars 101 arranged in a circumferential array; specifically, the number of main reinforcement bars 101 in the main reinforcement structure 1 in this embodiment is not limited, as long as it can meet the actual construction requirements.

[0020] The conveying module 2 is used to convey the main reinforcement structure 1 in the direction of the sleeving end for sleeving the spiral stirrup 502 and the welding end for welding the spiral stirrup 502 to the main reinforcement bar 101; In the prior art, when processing the main reinforcement structure 1, in order to fix each main reinforcement bar 101, a plurality of groups of reinforcing hoops in a circular structure are usually set, and a plurality of groups of main reinforcement bars 101 are welded to the reinforcing hoops in a circumferential array to form the main reinforcement structure 1. However, in the actual application process, when welding the main reinforcement bar 101 to the reinforcing hoop, it is difficult to ensure the uniformity of the positioning of a plurality of groups of main reinforcement bars 101 on the reinforcing hoop, and during the welding process, since the main reinforcement bar 101 has a certain length, a plurality of construction workers need to cooperate synchronously for welding, which is very troublesome; However, in this embodiment, by setting the positioning module 3, the positioning of a plurality of groups of main reinforcement bars 101 can be directly performed without manual positioning welding; wherein, by setting the conveying module 2, after the positioning of the main reinforcement structure 1 is completed, the main reinforcement structure 1 can be conveyed by the conveying module 2 in the direction of the sleeving end for sleeving the spiral stirrup 502 and the welding end for welding the spiral stirrup 502 to the main reinforcement bar 101; It should be noted that in this embodiment, the positioned main reinforcement structure 1 can be first conveyed by the conveying module 2 to the sleeving end for sleeving the spiral stirrup 502, the spiral stirrup 502 is sleeved on the main reinforcement structure 1, and after the sleeving is completed, the main reinforcement structure 1 is conveyed a certain distance by the conveying module 2 in the direction of the welding end to perform spot welding and fixing of the spiral stirrup 502 to the main reinforcement bar 101 of the main reinforcement structure 1 to form a complete reinforcement cage main structure.

[0021] In this embodiment, the sleeving end is provided with a sleeving module for sleeving the plain round steel bars spirally on the main reinforcement structure 1 to form spiral stirrups 502. Specifically, when the conveying module 2 conveys the main reinforcement structure 1 to the sleeving end, the plain round steel bars can be spirally sleeved on the main reinforcement structure 1 through the sleeving module to form spiral stirrups 502. Among them, the plain round steel bars in this embodiment can be hot-rolled plain round steel bars of HPB300 type, or HRB series hot-rolled ribbed steel bars can be used for replacement. This embodiment does not limit this, as long as the requirements of the construction standard are met.

[0022] The welding end is provided with a welding manipulator 4 for spot welding and fixing the spiral stirrups 502 to the main reinforcement bars 101. Specifically, the welding manipulator 4 in this embodiment can be an ABB welding robot or a KUKA welding robot. There is no limitation to this, as long as the actual welding requirements are met.

[0023] It can be explained that in this embodiment, the positioning module 3 can be used to position each main reinforcement bar 101 of the main reinforcement structure 1, and there is no need to pre-position and weld the main reinforcement bars 101 with reinforcing hoops. This not only improves the efficiency but also reduces the labor cost. After positioning, the main reinforcement structure 1 can be directly conveyed to the sleeving end by the conveying module 2, and the plain round steel bars are spirally sleeved on the main reinforcement structure 1 through the sleeving module to form spiral stirrups 502. In this embodiment, there is no need to pre-process the spiral stirrups 502 either. The spiral stirrups 502 can be directly bent and formed on the main reinforcement structure 1, further improving the forming efficiency of the reinforcement cage structure. After the spiral stirrups 502 are formed on the main reinforcement structure 1, the welding manipulator 4 can directly spot weld and fix the spiral stirrups 502 to the main reinforcement bars 101 of the main reinforcement structure 1, greatly improving the welding efficiency of the two. At the same time, in this embodiment, by sleeving and welding the spiral stirrups 502 on the main reinforcement structure 1 in sections, the phenomenon of the spiral stirrups 502 closing in under the action of elastic force is avoided, and the stability is higher.

[0024] In addition, when the sleeving module in this embodiment bends and forms the plain round steel bars on the main reinforcement structure 1, the starting end of the plain round steel bars needs to be pre-fixed to the main reinforcement bars 101 on the main reinforcement structure 1 by tying or spot welding to ensure the stability of the plain round steel bars wound around the main reinforcement structure 1.

[0025] Embodiment 2 On the basis of Embodiment 1, please refer to Figures 4 - 6, the conveying module 2 includes a first positioning cylinder 202, the first positioning cylinder 202 is connected to a first driving part 201 that drives it to reciprocate axially, and a plurality of groups of first arc-shaped positioning plates 203 are arranged in a circumferential array around the first positioning cylinder 202. A positioning groove 206 for embedding the main reinforcement bars 101 is provided on the first arc-shaped positioning plate 203. A limiting ring 205 coaxial with the first positioning cylinder 202 is fixedly arranged on the periphery of each first arc-shaped positioning plate 203 to limit the main reinforcement bars 101 embedded in the positioning groove 206. Among them, a first adjusting part is provided on the first positioning cylinder 202, and the first adjusting part is used to drive each first arc-shaped positioning plate 203 to move synchronously in a direction close to or away from the axis; it can be explained that when the main reinforcement structure 1 is conveyed in this embodiment, first, each main reinforcement bar of the main reinforcement structure 1 can be respectively embedded in the positioning groove 206 on each first arc-shaped positioning plate 203, and the first adjusting part is used to drive each first arc-shaped positioning plate 203 to move in a direction away from the axis of the first positioning cylinder 202, so that each main reinforcement bar 101 abuts against the limiting ring 205, thereby achieving the effect of clamping and positioning the main reinforcement bar 101. When it is necessary to convey the main reinforcement structure 1, the first driving part 201 can be used to drive the clamped main reinforcement structure 1 to move a certain distance in the direction of the sleeving end, so as to sleeved the spiral stirrup 502 on the main reinforcement structure 1. After completion, the first adjusting part can be used to drive each first arc-shaped positioning plate 203 to move in a direction close to the first positioning cylinder 202 (refer to Figure 8 ), so that the first arc-shaped positioning plate 203 is separated from the main reinforcement bar 101. Since the main reinforcement structure 1 is in the positioning state of the positioning module 3 at this time, even if the two are separated, each main reinforcement bar 101 can remain stable. Correspondingly, the first driving part 201 is used to drive the first positioning cylinder 202 to return to the initial position, so as to facilitate the conveyance of the main reinforcement structure 1 again, and so on; It should also be noted that the number of the first arc-shaped positioning plates 203 provided in this embodiment and the number of the positioning grooves 206 provided on each group of first arc-shaped positioning plates 203 need to correspond to the number of the main reinforcement bars 101, and no limitation is imposed on this; for example, four groups of first arc-shaped positioning plates 203 are provided in this embodiment, and three positioning grooves 206 are provided on each group of first arc-shaped positioning plates 203.

[0026] Please refer to Figure 4 、 Figure 7 and Figure 10, the positioning module 3 includes a second positioning cylinder 302, and a plurality of groups of second arc-shaped positioning plates 303 are arranged in a circumferential array around the second positioning cylinder 302. The second arc-shaped positioning plates 303 have the same structure as the first arc-shaped positioning plates 203, and positioning grooves 206 are also formed on the second arc-shaped positioning plates 303. Among them, a second adjusting portion is provided on the second positioning cylinder 302, and the second adjusting portion is used to drive each second arc-shaped positioning plate 303 to move synchronously in a direction close to or away from the axis; it can be explained that in the initial state, each main reinforcement bar 101 is also correspondingly embedded in the positioning grooves 206 on the second arc-shaped positioning plates 303. Since in this embodiment, the positioning module 3 is located at the sleeved end, after the main reinforcement bars 101 are embedded, the first section of smooth round bar can be directly bent and formed on the main reinforcement structure 1 through the sleeving module to form the first section of spiral stirrup 502. During the process of bending and forming the smooth round bar on the main reinforcement structure 1, a relatively large torsional force will be applied to the main reinforcement bars 101. In this embodiment, the second arc-shaped positioning plates 303 provided can give each main reinforcement bar 101 a supporting force during the forming process, preventing the main reinforcement bars 101 from being stressed and gathering towards the axis direction, and improving the stability of the bending and forming; Correspondingly, when the first section of spiral stirrup 502 is bent and formed, as the first adjusting portion drives each first arc-shaped positioning plate 203 to separate from the main reinforcement bar 101, the second arc-shaped positioning plates 303 in this embodiment always play a role of supporting and positioning the main reinforcement bars 101, ensuring the stability of the main reinforcement structure 1; It should also be noted that when the first driving portion 201 drives the first positioning cylinder 202 to reset to the initial position and clamps and positions the main reinforcement bars 101 again, in this embodiment, the second adjusting portion can be used to drive each second arc-shaped positioning plate 303 to separate from the main reinforcement bars 101, so that the first driving portion 201 can smoothly drive the main reinforcement bars 101 to move a certain distance towards the welding end, avoiding excessive friction between the main reinforcement bars 101 and the second arc-shaped positioning plates 303 and affecting normal transportation. After the section of spiral stirrup 502 is transported to the welding end, the spiral stirrup 502 can be spot-welded and fixed to the main reinforcement bars 101 through the welding manipulator 4. Repeating this process can complete the processing of the steel cage structure.

[0027] Please refer to Figures 6 - 7 and Figure 10, at the end of the first positioning cylinder 202, a first cylinder 213 is fixedly arranged, and at the end of the second positioning cylinder 302, a second cylinder 305 is fixedly arranged. The first adjusting part and the second adjusting part respectively include adjusting plates 309 slidably arranged in the positioning cylinders. The driving ends of the first cylinder 213 and the second cylinder 305 are respectively fixed to the adjusting plates 309. On the side of the second arc-shaped positioning plate 303 and the first arc-shaped positioning plate 203 close to the axis end of the positioning cylinder, positioning rods 311 are fixedly arranged, and positioning seats 312 are fixedly arranged on the positioning rods 311. Among them, several groups of guide grooves 308 are circumferentially arrayed on the cylinder walls of the first positioning cylinder 202 and the second positioning cylinder 302 respectively. Several groups of adjusting rods 310 are rotatably arranged circumferentially on the adjusting plates 309, and the other ends of the adjusting rods 310 are rotatably connected to the positioning seats 312. Among them, guiding parts are respectively arranged at the ends of the first positioning cylinder 202 and the second positioning cylinder 302 to limit the linear movement of each arc-shaped positioning plate along the direction of approaching or departing from the axis. It can be explained that in this embodiment, when driving each arc-shaped positioning plate to move in the direction of approaching or departing from the axis synchronously, the first cylinder 213 or the second cylinder 305 can be used to drive the adjusting plate 309 to move in the positioning cylinder respectively. During the movement of the adjusting plate 309, the connected arc-shaped positioning plate can be driven to slide along the guiding part through the adjusting rod 310, so as to achieve the effect of synchronous diffusion or gathering.

[0028] Among them, the guiding part includes a guiding disk 313 fixed to the end of the positioning cylinder. Several groups of guide rails 314 are circumferentially arrayed on the guiding disk 313, and guide rods 315 fixed to the arc-shaped positioning plate are slidably arranged in the guide rails 314. Specifically, when the arc-shaped positioning plate moves, it can be guided and limited by the guide rod 315 and the guide rail 314.

[0029] Please refer to Figures 1 - 2 、 Figures 4 - 6 and Figures 9 - 11 , as a further solution of this embodiment, the conveying module 2 includes a first driving part 201. The first driving part 201 is fixed on the base 6. A first limiting frame 225 is fixedly arranged at the driving end of the first driving part 201. The first limiting frame 225 is connected to the first positioning cylinder 202 through a first connecting component. A second limiting frame 301 is also fixed on the base 6. The second limiting frame 301 is connected to the second positioning cylinder 302 through a second connecting component. Specifically, in this embodiment, when driving the conveying module 2 to move, the first driving part 201 can first drive the first limiting frame 225 to move, and the first limiting frame 225 can synchronously drive the conveying module 2 to move through the first connecting component. It should be noted that the first driving part 201 of this embodiment can adopt a screw-nut transmission mechanism or a synchronous belt transmission mechanism, both of which are existing technologies. The specific structure and signal of this embodiment are not limited to meet the driving requirements.

[0030] In addition, the limiting ring 205 of this embodiment is rotatably arranged on one side of the support ring 204, and the support ring 204 is fixed to the first limiting frame 225 through the connecting frame 223.

[0031] In this embodiment, please refer to Figures 1 - 2 , the sleeving module includes a straightening machine 5 arranged on one side of the sleeving end. The straightening machine 5 is used to convey the smooth round steel bar towards the sleeving end. A second driving part 501 is also fixedly arranged on one side of the base 6. The driving end of the second driving part 501 is fixed to the straightening machine 5. Among them, the sleeving module further includes a rotating mechanism, and the rotating mechanism is used to drive the positioning module 3 to rotate; it can be explained that in the initial state, the straightening machine 5 is located on the side of the sleeving end away from the conveying module 2. The smooth round steel bar is conveyed towards the sleeving end through the straightening machine 5. The end of the smooth round steel bar is tied and fixed to the main reinforcement bar 101. The second driving part 501 and the rotating mechanism are started synchronously. When the rotating mechanism drives the positioning module 3 to rotate, the main reinforcement structure 1 can be synchronously driven by the positioning module 3. During this process, the second driving part 501 drives the straightening machine 5 to move towards the conveying module 2, and the conveyed smooth round steel bar can be spirally sleeved on the main reinforcement structure 1 to form a spiral stirrup 502; when a section of spiral stirrup 502 is formed, as the conveying module 2 conveys the main reinforcement structure 1, the second driving part 501 can synchronously drive the straightening machine 5 to reset to facilitate the formation of the next section of spiral stirrup 502.

[0032] In addition, the second driving part 501 can adopt a screw-nut transmission mechanism or a synchronous belt transmission mechanism, both of which adopt existing technologies. The specific structure and signal of this embodiment are not limited to meet the driving requirements.

[0033] As a further solution of this embodiment, in order to avoid interference between the main reinforcement bar 101 and the first connection component and the second connection component when the rotating mechanism drives the main reinforcement structure 1 to rotate; please refer to Figures 6 - 7 and Figure 10, positioning rings 209 are rotatably arranged at the ends of the first positioning cylinder 202 and the second positioning cylinder 302. The first connection assembly and the second connection assembly both include an upper positioning plate 208 and a lower positioning plate 211 fixedly connected to the positioning ring 209, and also include an upper connection plate 207 and a lower connection plate 210 fixed to the first limiting frame 225 and the second limiting frame 301. The position of the upper connection plate 207 corresponds to that of the upper positioning plate 208, and the position of the lower connection plate 210 corresponds to that of the lower positioning plate 211. Among them, the upper connection plate 207 and the upper positioning plate 208, and the lower connection plate 210 and the lower positioning plate 211 are respectively connected through connecting parts. It can be explained that in this embodiment, two sets of connecting parts are arranged on the first limiting frame 225 and the second limiting frame 301 and connected to the positioning ring 209. When the rotating mechanism drives the main reinforcement structure 1 to rotate, as the main reinforcement bar 101 rotates to the connecting part located on the upper side, the connecting part can be automatically opened so that the upper connection plate 207 and the upper positioning plate 208 are in a disconnected state, while the connecting part between the lower connection plate 210 and the lower positioning plate 211 remains in a connected state, so that the limiting frame is still in a state of positioning and supporting the positioning ring 209. When the main reinforcement bar 101 rotates between the two sets of connecting parts, the upper connecting part is reset to connect the upper connection plate 207 and the upper positioning plate 208 again. As the rotating mechanism continues to rotate, the connecting part located on the lower side is disconnected to avoid interference between the main reinforcement bar 101 and the connecting part; In this embodiment, through slots 221 are provided at the ends of the upper positioning plate 208, the lower positioning plate 211, the upper connecting plate 207 and the lower connecting plate 210. The connecting part includes a wedge-shaped plate 212 that is slidably inserted into the through slots 221 of the upper connecting plate 207 and the lower connecting plate 210. The wedge-shaped plate 212 is provided with an inclined guide surface 226. The other end of the wedge-shaped plate 212 is embedded in the through slot 221 of the positioning plate. A first support 214 is fixedly arranged on one side of the wedge-shaped plate 212. A second support 219 is fixedly arranged on the corresponding side of the positioning plate. A positioning hole 220 is provided in the second support 219. A limiting rod 215 that is slidably inserted into the positioning hole 220 is fixedly arranged on the side of the first support 214 facing the positioning plate. A third support 216 is fixedly arranged on one side of the connecting plate. A plug rod 217 that is slidably inserted into the third support 216 is fixedly arranged at the other end of the second support 219. A telescopic spring 218 is provided on the plug rod 217. One end of the telescopic spring 218 is fixed to the first support 214, and the other end is fixed to the third support 216. It can be explained that in the initial state, the limiting rod 215 is in a state of being inserted into the positioning hole 220. As the rotating mechanism drives the main reinforcement structure 1 to rotate, the main reinforcement bar 101 abuts against the inclined guide surface 226. Under the abutting action, the wedge-shaped plate 212 can be driven to contract into the through slot of the connecting plate. The wedge-shaped plate 212 can drive the limiting rod 215 to separate from the positioning hole 220 through the first support 214. The first support 214 can compress the telescopic spring 218 through the plug rod 217 to generate an elastic force. As the main reinforcement bar 101 passes over the connecting part, the telescopic spring 218 can drive each component to reset; In addition, please refer to Figures 11 - 12 , a clamping hole 224 is also provided at the end of the limiting rod 215 away from the first support 214. An electric push rod 222 for plugging and cooperating with the clamping hole 224 is fixedly arranged on the second support 219; specifically, a pressure sensor can be arranged on the inclined guide surface 226 to monitor whether the main reinforcement bar 101 moves to the inclined guide surface 226; It can be explained that in the initial state, after the limiting rod 215 is embedded in the positioning hole 220, the electric push rod 222 is embedded in the clamping hole 224 for limiting to improve the stability of the connecting part. When the main reinforcement bar 101 contacts the inclined guide surface 226, the pressure sensor can control the electric push rod 222 to contract through the controller so that the wedge-shaped plate 212 can slide. After a preset time, as the wedge-shaped plate 212 resets, the electric push rod 222 can drive the electric push rod 222 to be plugged into the clamping hole 224 again, and the automation degree and stability are improved synchronously.

[0034] In addition, please refer to Figure 6 and Figure 10, the rotating mechanism includes a toothed ring 304 fixed to the second positioning cylinder 302. A servo motor 307 is fixedly arranged on one side of the positioning ring 209, and a gear 306 meshing with the toothed ring 304 is fixedly arranged at the driving end of the servo motor 307. Specifically, when driving the main reinforcement structure 1 to rotate, the servo motor 307 can be used to drive the gear 306 to rotate. During the rotation of the gear 306, the second positioning cylinder 302 is driven to rotate by meshing with the toothed ring 304.

[0035] A welding method for spiral stirrup processing includes the following steps: Please refer to Figures 1 - 4 , S1. The positioning module 3 positions several groups of main reinforcement bars 101. S2. After the main reinforcement structure 1 is positioned, the conveying module 2 conveys the main reinforcement structure 1 towards the sleeving end for sleeving the spiral stirrup 502. S3. The spiral stirrup 502 is sleeved on the main reinforcement structure 1. S4. After sleeving is completed, the conveying module 2 conveys the main reinforcement structure 1 a certain distance towards the welding end to spot-weld and fix the spiral stirrup 502 to the main reinforcement bar 101 of the main reinforcement structure 1, forming a complete cage body structure of the reinforcement cage.

[0036] The above-disclosed are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
