Description

Technical Field

[0001] The present invention relates to the technical field of steel bar welding, and particularly to a steel bar welding device for building construction. Background Art

[0002] Steel bars are widely used materials in construction projects. Most of the uses of steel bars are as supporting skeletons. When using steel bars, because the manufacturing lengths of steel bars are different, it is often necessary to weld the steel bars to reach the required length for use. When welding steel bars, it can be divided into lap welding and butt welding.

[0003] For example, in the steel bar welding positioning device for building construction with the publication number of CN116393898B, through the rotation of the rotating shaft and the second gear, the ring body is driven to rotate. Through the rotation of the ring body and the action of four connecting rods I, four rotating plates are driven to rotate. Through the rotation of the rotating plates and the driving of the connecting rods II, four sliders slide along the sliding openings towards the openings at the same time, so that the four clamping blocks clamp the steel bar from the up, down, left, and right directions. Then, another steel bar is fixed in the same way, so that the two steel bars are coaxial, ensuring the welding accuracy. However, in actual use, when lap welding steel bars, one end of the steel bar needs to be bent, and the lap bending part of the steel bar is welded. Through bending, the two steel bars can be in a straight line after lap welding. During the lap welding process of the steel bar, it is not convenient to position the steel bar, which is not convenient for the subsequent workers to carry out lap welding on the steel bar. Moreover, when lap welding steel bars, the lap lengths of different diameters have rated lengths and rated angles. If the length is too small, it will affect the subsequent welding length and the structural strength after welding. If the angles of the lap ends of the two steel bars are different, it cannot be guaranteed that the two steel bars are in a straight line after welding at the lap end, and it is easy to cause gaps in the butt joint of the two steel bars, affecting the welding quality. During the lap welding process of the steel bar, it is not convenient to measure the angle and length of the lap bending part of the steel bar, and there are certain defects in use.

[0004] Therefore, we propose a steel bar welding device for building construction to solve the problems raised above. Summary of the Invention

[0022] By adopting the above technical solution, it is convenient for the staff to adjust the angle of the welding torch.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: For the steel bar welding device for building construction, when lapping and welding the steel bar body, it is convenient to butt the steel bar body. And when butt-welding the lapping and bending part, the steel bar body can be positioned, and it is convenient to measure the length and angle of the lapping and bending part of the steel bar body, avoiding welding the steel bar body whose length and angle do not meet the requirements, ensuring the quality and strength after steel bar welding, and improving the practicability; 1. When lapping and welding the steel bar body, place the two steel bar bodies on two fixed seats respectively. Then start the rotating motor to drive the bidirectional lead screw to rotate. After the bidirectional lead screw rotates, it can drive the two movable frames to approach each other, and then drive the positioning seats to approach each other. After the positioning seats move, they drive the rollers to move to the slope on one side of the movable plate. Before welding the steel bar body, the top surface height of the movable plate can be adjusted by the electric push rod according to the thickness of the steel bar body. After the rollers contact the movable plate and move with the positioning seats, they can drive the rollers to move upward, causing the movable rod to move upward. After the movable rod moves upward, it can drive the rotating shaft to rotate through the meshing of the toothed plate and the rotating gear, and then drive the two positioning members to rotate. After the positioning members rotate, they can position the upper part of the steel bar body, fixing the steel bar body. And at this time, the rollers move to the horizontal position of the top surface of the movable plate. Then the two movable frames continue to move, which can drive the steel bar body to move, so that the lapping and bending parts of the two steel bar bodies can be butted. Therefore, when butting the steel bar body, the steel bar body can be positioned, avoiding the displacement of the steel bar body during the subsequent welding process, and improving the convenience and practicability; 2. When placing the steel bar body, make the lapping and bending part of the steel bar body abut against the L-shaped frame. After that, when the two steel bar bodies move closer to each other, they can push the L-shaped frame to rotate, drive the rotating rod to rotate, cause the torsion spring to deform, and the end of the steel bar body is relatively straight, so that one side of the L-shaped frame fits with one end of the steel bar body. The L-shaped frame rotates from straight to inclined, and after rotation, it fits with one end of the steel bar body, so that the rotation angle of the L-shaped frame is the inclination angle of the bent end of the steel bar body. The angle of the lapping and bending part of the steel bar body can be obtained by the position of the pointer on the angle scale line. During the rotation of the L-shaped frame, the support plate can be rotated. During the rotation of the support plate, a part of one side area fits with the steel bar body. As the support plate rotates, the support rod can slide on the moving plate, causing the tension spring to deform. After the L-shaped frame rotates and fits with the steel bar body, the support plate rotates and is parallel to the lapping and bending part of the steel bar body. During the subsequent movement of the steel bar body, it can drive the L-shaped frame to move, causing the movable seat to slide on the fixed rod, so that the reset spring can be stretched. As the movable seat moves continuously, the reaction force of the reset spring on the L-shaped frame becomes larger and larger. At this time, the whole support plate fits with the steel bar body. According to the lever principle, it can be known that the force arm of the reaction force of the reset spring driving the L-shaped frame to rotate is shorter, and the force arm of the L-shaped frame supported by the support plate is longer, so that it is not easy for the L-shaped frame to continue to rotate after rotating to fit with the steel bar body. Then, make the lapping and bending parts of the steel bar bodies butt and fit. The length of the lapping and bending part of the steel bar body can be observed through the length scale line on the L-shaped frame. Therefore, when docking the steel bar bodies, it is convenient to measure the angle and length of the lapping and bending part of the steel bar body, which is convenient for observation, avoids welding when the length and angle of the lapping and bending part of the steel bar body do not meet the requirements, and also avoids adding additional processes for measuring length and angle before welding the steel bar bodies, improving the convenience and welding efficiency. 3. When welding after the steel bar bodies are docked, the staff can press down the sliding plate to move downward, so that the sliding plate slides on the vertical rod and stretches the adaptation spring, causing the welding torch to move downward. The lapping and bending part of the steel bar body is welded by the welding torch. Since the cross-section of the steel bar body is circular, when welding, due to the limited bonding area after the two steel bar bodies are bonded, the staff needs to continuously move the welding torch. The staff presses down the sliding plate and can continuously rotate the welding torch to adjust the position of the welding torch, so that the spherical part rotates on the sliding plate, which is convenient for continuous welding of the lapping and bending part of the steel bar body. And the elastic coefficient of the adaptation spring is small, which is convenient for the staff to operate, improving the convenience and practicality. BRIEF DESCRIPTION OF THE DRAWINGS

Through grooves 202 are symmetrically formed through the top of the workbench 1. Positioning seats 203 are arranged above both of the two through grooves 202. Installation grooves 204 are symmetrically formed through both sides of the positioning seat 203. A rotating shaft 205 is rotatably connected inside the installation groove 204. A positioning member 206 is fixedly installed on the outer part of the rotating shaft 205. A rubber layer is wrapped around the outer part of the positioning member 206; Positioning blocks 208 are symmetrically installed on one side of the positioning seat 203. One end of each of the two rotating shafts 205 passes through the positioning seat 203 and is fixedly installed with a rotating gear 207. A movable rod 209 is slidably connected inside the positioning block 208. A toothed plate 2091 is fixedly installed above one side of the movable rod 209. The rotating gear 207 is meshed with the toothed plate 2091. The bottom end of the movable rod 209 is fixedly installed with an installation frame 210. A roller 211 is arranged at the bottom of the installation frame 210; Movable frames 212 are fixedly installed at the bottom of both of the two positioning seats 203. The movable frames 212 are slidably connected with the through grooves 202. Fixed blocks 213 are symmetrically installed on both sides of the two through grooves 202 at the bottom of the workbench 1. A bidirectional lead screw 214 is rotatably connected between the two fixed blocks 213. A rotating motor 215 is fixedly installed on one side of the right fixed block 213 at the bottom of the workbench 1. The output end of the rotating motor 215 passes through the right fixed block 213 and is fixedly connected with the bidirectional lead screw 214; Receiving grooves 216 are formed on both sides of the two through grooves 202 at the top of the workbench 1. Movable plates 217 are arranged inside each of the two receiving grooves 216 on each side. A slope is arranged on one side of the movable plate 217. A connecting plate 218 is fixedly installed at the bottom of the movable plate 217. The connecting plate 218 is slidably connected with the workbench 1. Installation plates 219 are fixedly installed at the bottom of the two connecting plates 218. An electric push rod 220 is fixedly installed on one side above the installation plate 219 at the bottom of the workbench 1. The movable end of the electric push rod 220 is fixedly connected with the installation plate 219.

[0028] Example 1: As Figures 1-4As shown in the figure, when butt welding the steel bar body 102, the two steel bar bodies 102 are respectively placed on two fixed seats 201. Then, the rotation motor 215 is started to drive the bidirectional lead screw 214 to rotate. After the bidirectional lead screw 214 rotates, it can drive the two movable frames 212 to approach each other, and then drive the positioning seats 203 to approach each other. After the positioning seats 203 move, the rollers 211 are driven to move to the slope on one side of the movable plate 217. Before welding the steel bar body 102, the top surface height of the movable plate 217 can be adjusted by the electric push rod 220 according to the thickness of the steel bar body 102. After the rollers 211 contact the movable plate 217, as the positioning seats 203 move, the rollers 211 can be driven to move upward, so that the movable rod 209 moves upward. After the movable rod 209 moves upward, the rotation shaft 205 can be driven to rotate through the engagement of the toothed plate 2091 and the rotating gear 207, and then the two positioning members 206 can be driven to rotate. After the positioning members 206 rotate, the upper part of the steel bar body 102 can be positioned, so that the steel bar body 102 is fixed. At this time, the rollers 211 move to the horizontal position of the top surface of the movable plate 217. Then, when the two movable frames 212 continue to move, the steel bar body 102 can be driven to move, so that the butt bending parts of the two steel bar bodies 102 are butted. Thus, when the steel bar body 102 is butted, the steel bar body 102 can be positioned, avoiding the displacement of the steel bar body 102 during the subsequent welding process, and improving the convenience and practicability.

[0029] On the top of the workbench 1, two groups of mounting blocks 221 are symmetrically installed at the butt ends of the two steel bar bodies 102. A fixing rod 222 is fixedly installed between every two mounting blocks 221 in each group. The outer part of the fixing rod 222 is slidably connected with a movable seat 223. At the same time, a guide rod 224 is slidably connected to the lower part inside the movable seat 223. The two ends of the guide rod 224 are fixedly connected with the two mounting blocks 221. A return spring 225 is sleeved on the outer part of the fixing rod 222 on one side of the movable seat 223. The two ends of the return spring 225 are respectively fixedly connected with one side mounting block 221 and the movable seat 223. A rotating rod 227 is rotatably connected to the top of the movable seat 223. An L-shaped frame 226 is arranged on one side above the fixing rod 222. The rotating rod 227 is fixedly connected with the L-shaped frame 226. A torsion spring 228 is sleeved on the outer part of one side of the rotating rod 227. The two ends of the torsion spring 228 are respectively fixedly connected with the L-shaped frame 226 and the movable seat 223. An angle scale line is arranged on the top of the movable seat 223. A pointer 229 is fixedly installed on one side of the L-shaped frame 226 above the angle scale line. On one side of the L-shaped frame 226, mounting rods 230 are symmetrically installed. A moving plate 231 is slidably connected to the outside of the two mounting rods 230. On one side of the moving plate 231, tension springs 232 are sleeved on the outside of the two mounting rods 230. At the same time, the two ends of the tension spring 232 are fixedly connected to the mounting rod 230 and the moving plate 231 respectively; On one side of the moving plate 231 and between the two mounting rods 230, support rods 233 are symmetrically installed. At the end of the two support rods 233 away from the moving plate 231, a support plate 234 is fixedly installed. And length scale lines are provided on the top of the L-shaped frame 226.

[0030] Embodiment 2: As Figures 1-2 and Figures 5-8As shown in the figure, when placing the steel bar body 102, the lapping and bending part of the steel bar body 102 is abutted against the L-shaped frame 226. Then, when the two steel bar bodies 102 move closer to each other, they can push the L-shaped frame 226 to rotate, drive the rotating rod 227 to rotate, and cause the torsion spring 228 to deform. Moreover, the end of the steel bar body 102 is relatively straight, so that one side of the L-shaped frame 226 fits with one end of the steel bar body 102. The L-shaped frame 226 rotates from straight to inclined and then fits with one end of the steel bar body 102 after rotation. The rotation angle of the L-shaped frame 226 is the inclination angle of the bent end of the steel bar body 102. The angle of the lapping and bending part of the steel bar body 102 can be obtained through the position of the pointer 229 on the angle scale line. During the rotation of the L-shaped frame 226, the support plate 234 can be rotated. During the rotation of the support plate 234, a part of one side area fits with the steel bar body 102. As the support plate 234 rotates, the support rod 233 can slide on the moving plate 231, causing the tension spring 232 to deform. After the L-shaped frame 226 rotates and fits with the steel bar body 102, the support plate 234 rotates to be parallel to the lapping and bending part of the steel bar body 102. During the subsequent movement of the steel bar body 102, it can drive the L-shaped frame 226 to move, causing the movable seat 223 to slide on the fixed rod 222, so that the return spring 225 can be stretched. As the movable seat 223 continuously moves, the reaction force of the return spring 225 on the L-shaped frame 226 becomes larger and larger. At this time, the entire support plate 234 fits with the steel bar body 102. According to the lever principle, it can be known that the lever arm of the reaction force of the return spring 225 driving the L-shaped frame 226 to rotate is shorter, and the lever arm of the L-shaped frame 226 supported by the support plate 234 is longer, making it difficult for the L-shaped frame 226 to continue rotating after rotating to fit with the steel bar body 102. Then, the lapping and bending parts of the steel bar body 102 are butted and fitted. The length of the lapping and bending part of the steel bar body 102 can be observed through the length scale line on the L-shaped frame 226. Therefore, when butt-jointing the steel bar body 102, it is convenient to measure the angle and length of the lapping and bending part of the steel bar body 102, which is convenient for observation, avoids welding when the length and angle of the lapping and bending part of the steel bar body 102 do not meet the requirements, and also avoids adding additional length measurement procedures and angle measurement procedures before welding the steel bar body 102, improving the convenience and welding efficiency.

[0031] Welding assembly 3, arranged on one side of the top of the workbench 1; The welding assembly 3 includes support blocks 301 symmetrically installed on one side of the top of the workbench 1 between the two through grooves 202. A positioning rod 302 is fixedly installed between the two support blocks 301. A moving frame 303 is slidably connected to the outside of the positioning rod 302. And vertical rods 304 are symmetrically installed on the top of the moving frame 303; A sliding plate 305 is slidably connected to the outside of the two vertical rods 304, and a pair of adaptive springs 306 are sleeved on the outside of the two vertical rods 304 above the sliding plate 305. The two ends of the adaptive spring 306 are fixedly connected to the sliding plate 305 and the vertical rod 304 respectively. Meanwhile, a spherical member 307 is hinged to one side inside the sliding plate 305, and a welding torch 308 is fixedly installed inside the spherical member 307.

[0032] Embodiment 3: As Figure 1 and Figure 9 shown, when welding after the butt joint of the steel bar body 102, the worker can press down the sliding plate 305 to move downward, so that the sliding plate 305 slides on the vertical rod 304 and stretches the adaptive spring 306, causing the welding torch 308 to move downward. The welding torch 308 is used to weld the overlapping and bent part of the steel bar body 102. Since the cross-section of the steel bar body 102 is circular, when welding, due to the limited contact area after the two steel bar bodies 102 are fitted together, the worker needs to continuously move the welding torch 308. The worker presses down the sliding plate 305 and can continuously rotate the welding torch 308 to adjust the position of the welding torch 308, so that the spherical member 307 rotates on the sliding plate 305, which is convenient for continuous welding of the overlapping and bent part of the steel bar body 102. Moreover, the elastic coefficient of the adaptive spring 306 is small, which is convenient for the worker to operate and improves the convenience and practicality.

[0033] Working principle: When using this steel bar welding device for building construction, first, according to Figures 1-9As shown in the figure, when lap welding the steel bar body 102, the two steel bar bodies 102 are respectively placed on two fixed seats 201. Then, the rotation motor 215 is started to drive the bidirectional lead screw 214 to rotate. After the bidirectional lead screw 214 rotates, it can drive the two movable frames 212 to approach each other, and then drive the positioning seats 203 to approach each other. After the positioning seats 203 move, the rollers 211 are driven to move to the slope on one side of the movable plate 217. Before welding the steel bar body 102, the top surface height of the movable plate 217 can be adjusted by the electric push rod 220 according to the thickness of the steel bar body 102. After the rollers 211 contact the movable plate 217, as the positioning seats 203 move, the rollers 211 can be driven to move upward, so that the movable rod 209 moves upward. After the movable rod 209 moves upward, the rotation shaft 205 can be driven to rotate through the engagement of the toothed plate 2091 and the rotating gear 207, and then the two positioning members 206 can be driven to rotate. After the positioning members 206 rotate, the upper part of the steel bar body 102 can be positioned, so that the steel bar body 102 is fixed. At this time, the rollers 211 move to the horizontal position of the top surface of the movable plate 217. Then, the two movable frames 212 continue to move, which can drive the steel bar body 102 to move, and then the lap bending parts of the two steel bar bodies 102 can be butted. Therefore, when the steel bar bodies 102 are butted, the steel bar bodies 102 can be positioned, avoiding the displacement of the steel bar bodies 102 during the subsequent welding process, and improving the convenience and practicability; When placing the steel bar body 102, the overlapping bending part of the steel bar body 102 is abutted against the L-shaped frame 226. Then, when the two steel bar bodies 102 move closer to each other, they can push the L-shaped frame 226 to rotate, drive the rotating rod 227 to rotate, and cause the torsion spring 228 to deform. Moreover, the end of the steel bar body 102 is relatively straight, so that one side of the L-shaped frame 226 fits with one end of the steel bar body 102. The L-shaped frame 226 rotates from straight to inclined, and after rotation, it fits with one end of the steel bar body 102. The rotation angle of the L-shaped frame 226 is the inclination angle of the bent end of the steel bar body 102. The angle of the overlapping bending part of the steel bar body 102 can be obtained through the position of the pointer 229 on the angle scale line. And during the rotation of the L-shaped frame 226, the support plate 234 can be rotated. During the rotation of the support plate 234, a part of one side area fits with the steel bar body 102. As the support plate 234 rotates, the support rod 233 can slide on the moving plate 231, causing the tension spring 232 to deform. After the L-shaped frame 226 rotates and fits with the steel bar body 102, the support plate 234 rotates to be parallel to the overlapping bending part of the steel bar body 102. During the subsequent movement of the steel bar body 102, it can drive the L-shaped frame 226 to move, causing the movable seat 223 to slide on the fixed rod 222, so that the return spring 225 can be stretched. As the movable seat 223 moves continuously, the reaction force of the return spring 225 on the L-shaped frame 226 becomes larger and larger. At this time, the whole support plate 234 fits with the steel bar body 102. According to the lever principle, it can be known that the force arm of the reaction force of the return spring 225 driving the L-shaped frame 226 to rotate is shorter, and the force arm of the L-shaped frame 226 supported by the support plate 234 is longer, making it difficult for the L-shaped frame 226 to continue rotating after rotating to fit with the steel bar body 102. Then, the overlapping bending parts of the steel bar bodies 102 are butted and fitted. The length of the overlapping bending part of the steel bar body 102 can be observed through the length scale line on the L-shaped frame 226. Thus, when docking the steel bar body 102, it is convenient to measure the angle and length of the overlapping bending part of the steel bar body 102, which is convenient for observation, avoids welding when the length and angle of the overlapping bending part of the steel bar body 102 do not meet the requirements, and also avoids adding additional procedures for measuring length and angle before welding the steel bar body 102, improving the convenience and welding efficiency. When welding after docking the steel bar bodies 102, the staff can press down the sliding plate 305 to move downward, so that the sliding plate 305 slides on the vertical rod 304 and stretches the adaptive spring 306, causing the welding torch 308 to move downward. The overlapping bending part of the steel bar body 102 is welded by the welding torch 308. And since the cross-section of the steel bar body 102 is circular, during welding, due to the limited fitting area after the two steel bar bodies 102 are fitted, the staff needs to continuously move the welding torch 308. The staff presses down the sliding plate 305 and can continuously rotate the welding torch 308 to adjust the position of the welding torch 308.The spherical member 307 is rotated on the sliding plate 305, which facilitates continuous welding of the lap bending portion of the reinforcing bar body 102. Moreover, since the elastic coefficient of the spring 306 is small, it is convenient for the staff to operate, improving the convenience and practicality.
