A reinforcing steel bar welding device for reinforced concrete cement pipes

Abstract

This application discloses a welding device for reinforced concrete cement pipes, relating to the field of reinforcing bar welding technology. It includes a support frame and a working assembly. The working assembly provides a welding torch structure that rotates around the annular reinforcing bar, allowing for continuous cyclical operation of multiple welding points. This reduces reliance on manual labor, lowers labor intensity, ensures uniform welding quality, and improves overall welding quality. Once the annular and long reinforcing bars are fixed in the required positions, the first hydraulic telescopic rod extends and retracts to control the movement of the first support plate, controlling the optimal working distance between the welding torch and the annular reinforcing bar welding point. The second hydraulic telescopic rod extends and retracts to bring the abutment block into contact with the annular reinforcing bar. Simultaneously, the third hydraulic telescopic rod extends and retracts, driving the second support plate to move, causing the support roller to abut against the other side of the annular reinforcing bar, providing support and balance. After welding one point, the abutment is released, and the drive motor drives the drive gear to rotate, causing the gear ring to rotate and change the position of the welding torch to reach another welding point for continued welding.

Description

Technical Field

[0001] This utility model relates to the field of steel bar welding technology, and in particular to a steel bar welding device for reinforced concrete cement pipes. Background Technology

[0002] Reinforced concrete cement pipe is a prefabricated pipe made primarily of cement and steel bars. The steel bars form a mesh structure inside the concrete, evenly distributed within the pipe wall to enhance the overall strength of the pipe. Multiple steel bars are welded together between several rings using a welding device to form a tubular steel cage, thereby enhancing the structural performance of the cement pipe.

[0003] However, during the welding process, the welding gun needs to be moved or its position adjusted frequently by the operator. This requires the intermittent operation of positioning, welding, and moving point by point, which can easily lead to uneven weld strength and incomplete welds due to differences in operating techniques.

[0004] To address these issues, we provide a steel reinforcement welding device for reinforced concrete cement pipes. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5As shown, a steel bar welding device for reinforced concrete cement pipes includes a support frame 1 and a working component 2. The working component 2 is installed at the bottom of the support frame 1. The working component 2 includes an annular bracket 201 fixedly connected to the bottom of the support frame 1. A toothed ring 202 is rotatably connected to the inner side of the annular bracket 201 through a slot. A limiting ring plate 203 is rotatably connected to the other side of the toothed ring 202 through a slot. Both ends of the limiting ring plate 203 are fixedly connected to the annular bracket 201. A first bracket 2 is fixedly connected to one side of the inner wall of the toothed ring 202. 04. A first hydraulic telescopic rod 205 is installed on one side of the first bracket 204. The telescopic end of the first hydraulic telescopic rod 205 is fixedly connected to the first support plate 206. A welding torch 207 is installed in the middle of the other end of the first support plate 206. The toothed ring 202 rotates under the clamping constraint of the annular bracket 201 and the limiting ring plate 203, which drives the first bracket 204 to rotate and change the position of the welding torch 207. The telescopic movement of the first support plate 206 is controlled by the telescopic movement of the first hydraulic telescopic rod 205 to control the optimal working distance between the welding torch 207 and the annular steel bar.

[0024] Furthermore, a second hydraulic telescopic rod 208 is installed on both sides of the first support plate 206. The telescopic end of the second hydraulic telescopic rod 208 is fixedly connected to a stop block 209. The telescopic extension of the second hydraulic telescopic rod 208 causes the stop block 209 to abut against the annular steel bar to prevent displacement.

[0025] Furthermore, a drive motor 210 is installed on one side of the annular bracket 201. The output end of the drive motor 210 is connected to a drive gear 211 via a shaft key. The outer side of the drive gear 211 meshes with the gear ring 202. The drive motor 210 drives the drive gear 211 to rotate, causing the gear ring 202 to rotate accordingly.

[0026] Furthermore, a second bracket 212 is fixedly connected to the other side of the inner wall of the toothed ring 202. A third hydraulic telescopic rod 213 is installed on one side of the second bracket 212. A second support plate 214 is fixedly connected to the telescopic end of the third hydraulic telescopic rod 213. A support roller 215 is fixedly connected to the other end of the second support plate 214. The second bracket 212 moves with the toothed ring 202. The telescopic movement of the third hydraulic telescopic rod 213 drives the second support plate 214 to move, so that the support roller 215 abuts against the other side of the ring-shaped steel bar to provide support and balance.

[0027] Furthermore, a fourth hydraulic telescopic rod 216 is installed at the top of the support frame 1. The telescopic end of the fourth hydraulic telescopic rod 216 is fixedly connected to a limiting tooth block 217. The two sides of the limiting tooth block 217 and the support frame 1 form a sliding structure through the slots. The extension and retraction of the fourth hydraulic telescopic rod 216 causes the limiting tooth block 217 to abut against the outer side of the toothed ring 202, thereby completing the locking control of the toothed ring 202 and ensuring the stability of the welding torch 207.

[0028] Furthermore, a support plate 3 is fixedly connected to the bottom end of the annular bracket 201. A fifth hydraulic telescopic rod 4 is installed at the bottom end of the support plate 3. A base 5 is fixedly connected to the bottom end of the fifth hydraulic telescopic rod 4. Push rods 6 are fixedly connected to both sides of the base 5. A caster wheel 7 is installed at the bottom of the base 5. A sixth hydraulic telescopic rod 8 is installed on the surface of the base 5. A support leg 9 is fixedly connected to the telescopic end of the sixth hydraulic telescopic rod 8. The fifth hydraulic telescopic rod 4 drives the support plate 3 to move and adjust the height to improve flexibility. The caster wheel 7 and the sixth hydraulic telescopic rod 8 work together to form an interchangeable support, realizing the conversion between the fixed support and the moving mode of the device, which is convenient to use. The push rod 6 makes it convenient for the user to push the device in the moving mode, which is convenient for welding the next set of annular steel bars.

[0029] Furthermore, a guide frame 10 is slidably connected to the middle of the base 5 via a slot, and a guide rod 11 is slidably connected to the inner side of the guide frame 10 via a slot. A fixing plate 12 is fixedly connected to the bottom of the guide rod 11. The slot connection between the guide frame 10 and the base 5 ensures the connection state when the height of the base 5 changes. The guide frame 10 slides on the guide rod 11 to prevent displacement. The fixing plate 12 is fixedly supported by connecting to the ground with screws, etc.

[0030] Working principle: In use, firstly, the ring-shaped steel bar and the long steel bar are fixed in the required positions. The user moves the device in moving mode using the push rod 6 to align the welding torch 207 with the ring-shaped steel bar. The sixth hydraulic telescopic rod 8 extends and retracts, causing the support leg 9 to extend and provide support. The extension and retraction of the first hydraulic telescopic rod 205 controls the movement of the first support plate 206 to control the optimal working distance between the welding torch 207 and the ring-shaped steel bar. Secondly, the extension and retraction of the second hydraulic telescopic rod 208 causes the abutment block 209 to abut against the ring-shaped steel bar to prevent displacement. The extension and retraction of the third hydraulic telescopic rod 213 causes the second support plate 214 to move, causing the support roller 215 to abut against the other side of the ring-shaped steel bar to provide support and balance. The welding torch 207 completes the welding. Thirdly, the drive motor 210 drives the drive gear 211 to rotate, causing the gear ring 202 to rotate accordingly. The gear ring 202 rotates in a ring shape. The bracket 201 rotates under the clamping constraint of the limiting ring plate 203, causing the first bracket 204 to rotate and change the position of the welding torch 207. The fourth hydraulic telescopic rod 216 extends and retracts, causing the limiting tooth block 217 to abut against the outer side of the toothed ring 202, completing the locking control of the toothed ring 202 and ensuring the stability of the welding torch 207. Welding is completed on the welding points of the same ring-shaped steel bar. In the fourth step, the universal wheel 7 and the sixth hydraulic telescopic rod 8 extend and retract, driving the support leg 9 to form an exchange support, realizing the conversion between the fixed support and the moving mode of the device, which is convenient to use. The push rod 6 allows the user to push the device in the moving mode, which is convenient for welding the next set of ring-shaped steel bars. The guide frame 10 slides on the guide rod 11 to prevent displacement. The fixed plate 12 is connected to the ground by screws, etc. to achieve fixed support. In this way, the use of a steel bar welding device for reinforced concrete cement pipes is completed.
