Description

Technical Field

[0001] The utility model relates to a positioning auxiliary device, in particular to an inner rolled pipe welding positioning auxiliary device, belonging to the technical field of pipeline welding. Background Art

[0002] The internally rolled pipe has the advantages of high efficiency, stability, high temperature resistance, corrosion resistance and high strength. It is a tool for transporting oil, natural gas and water resources. The pipes of the pipeline are generally steel pipes, which are connected into long-distance pipelines using welding and flange connection devices, and valves are used for opening and closing control and flow regulation. The pipeline requires multiple pipe sections to be placed in appropriate positions and then welded together. Positioning auxiliary devices are required during the welding process.

[0003] According to the patent number CN218745942U, a welding pipeline auxiliary positioning device is disclosed, which includes two supporting components and a circumferentially arranged balance component. The supporting component includes an arc-shaped component 1, an arc-shaped component 2 and a connecting component. The connecting component includes two groups of connecting blocks and two groups of fixing screws.

[0004] During the implementation of the above scheme, the overlap of the two pipes during welding can be ensured, and the misalignment of the pipes during welding can be avoided. However, during the implementation of the above scheme, it is difficult to clamp pipes of different diameters, and the positioning steps are relatively cumbersome. The pipes need to be fixed by manually turning the nuts and screws many times, which reduces work efficiency. To this end, we provide an internally rolled pipe welding positioning auxiliary device to solve the above problems. Utility Model Content

[0027] The utility model embodiment provides an inner rolled pipe welding positioning auxiliary device.

[0028] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a positioning platform 1, a slide groove 2 is provided on the top surface of the positioning platform 1, a clamping mechanism 3 is arranged inside the slide groove 2, and there are two slide grooves 2 in total in the device, and two clamping mechanisms 3 are arranged inside each slide groove 2. Through the setting of these two groups of clamping mechanisms 3, the two inner rolled pipes required for welding can be clamped and fixed, so that the pipeline remains stable during the welding process, and the shaking of the pipeline is prevented from affecting the welding operation.

[0029] See also Figure 2 , Figure 3 and Figure 4 The inner wall of the slide 2 is rotatably connected with a bidirectional threaded rod 4, and one end of the bidirectional threaded rod 4 is fixedly connected with a driven rod 5. The bidirectional threaded rod 4 is a prior art and will not be described in detail in this application. The two bidirectional threaded rods 4 rotate in opposite directions. When the drive motor 8 is started, the two bidirectional threaded rods 4 can be driven to rotate in different directions. However, since the two bidirectional threaded rods 4 rotate in opposite directions, the threaded sliders 301 on the two bidirectional threaded rods 4 can keep sliding synchronously inside the slide 2 to facilitate synchronous clamping of the pipeline.

[0030] The interior of the positioning platform 1 is rotatably connected to a rotating rod 6, and the outer surfaces of the driven rod 5 and the rotating rod 6 are fixedly connected to pulleys 7. The two pulleys 7 are connected by a belt transmission. When the rotating rod 6 rotates, the driven rod 5 will also rotate through the transmission action of the belt, thereby providing power for the subsequent clamping mechanism 3 to clamp pipes of different diameters. Two pulleys 7 are fixed on the outer surface of the rotating rod 6, which correspond to the pulleys 7 on the two driven rods 5 respectively.

[0031] See also Figure 1 A drive motor 8 is fixedly installed on the outside of the positioning platform 1, and the rotating rod 6 is fixedly connected to the output shaft of the drive motor 8. The drive motor 8 is a power source for the drive device to clamp and fix pipes of different diameters. The drive motor 8 is a prior art and will not be described in detail in this application. A fixing plate that can fix and support the drive motor 8 is installed on the outer surface of the positioning platform 1, which can prevent the drive motor 8 from rotating during operation.

[0032] See also Figure 1 , Figure 2 and Figure 3 The top surface of the positioning platform 1 is fixedly connected to a support column 9, and the top surface of the support column 9 is fixedly connected to a welding platform 10. The height of the welding platform 10 is on the same horizontal plane as the lowest point of the clamped inner rolled pipe. When the inner rolled pipe is clamped by the clamping mechanism 3, the welding platform 10 can support the end of the pipe, making it easier to weld the pipe.

[0033] Please refer again Figure 1 The top surface of the positioning platform 1 is fixedly connected with a placement rack 11, and the top surface of the positioning platform 1 is fixedly connected with a placement rack 2 12. Through the arrangement of the placement rack 11 and the placement rack 2 12, the inner rolled pipe that needs to be welded can be supported, so that the pipeline can be supported during the welding positioning process, reducing the work intensity of the staff to manually lift the pipeline.

[0034] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 The clamping mechanism 3 includes a threaded slider 301 slidably connected to the slide groove 2, the threaded slider 301 is threadedly connected to the bidirectional threaded rod 4, and the top surface of the threaded slider 301 is fixedly connected with a connecting block 302. The rotation of the bidirectional threaded rod 4 can drive the two threaded sliders 301 to move closer or farther away from each other, thereby adjusting the relative distance between the two clamping claws 303, so that the clamping claws 303 can clamp the pipeline, which is convenient for subsequent pipeline welding work.

[0035] A clamping claw 303 is provided above the connection block 302 . The clamping claw 303 is adapted to the diameter of the pipe to be welded. When welding pipes of different diameters, it is only necessary to replace the clamping claw 303 adapted to the pipe.

[0036] The inner wall of the clamping claw 303 is fixedly connected with a buffer pad 308, which can provide a certain buffering effect for the clamping claw 303 to clamp and fix the pipe, thereby preventing the clamping claw 303 from damaging the surface of the pipe during the clamping process. The buffer pad 308 can also increase the friction between the clamping claw 303 and the pipe, thereby improving the clamping effect of the clamping claw 303.

[0037] The top surface of the connecting block 302 is fixedly connected with a clamping column 304, and the bottom surface of the clamping claw 303 is provided with a clamping hole 305. The clamping column 304 is plugged into the clamping hole 305. Through the setting of the clamping column 304 and the clamping hole 305, the clamping claw 303 can be fixed to the top of the connecting block 302. When the connecting block 302 moves with the sliding of the threaded slider 301, it can drive the clamping claw 303 to move, so that the clamping claw 303 clamps the welding pipe.

[0038] The outer surfaces of the threaded slider 301 and the clamping claw 303 are both provided with a socket 306, and the inside of the socket 306 is slidably connected with a pin 307. The arrangement of the socket 306 and the pin 307 can increase the stability between the connecting block 302 and the clamping claw 303, and facilitate the disassembly and replacement of the clamping claw 303. There is a magnetic attraction effect between the end of the pin 307 and the inner wall of the socket 306. When the pin 307 is inserted into the socket 306, under the action of the magnet, the pin 307 can be stably plugged into the socket 306, thereby ensuring the stability of the connection between the clamping claw 303 and the connecting block 302.

[0039] Working principle: When welding is required for the inner rolled pipe, the staff will place the two pipes on the placement rack 1 11 and the placement rack 2 12, and fit the ends of the two pipes to be welded on the welding platform 10, and then select the clamping claw 303 that matches it according to the diameter of the pipe, plug the clamping claw 303 into the connecting block 302, and then insert the pin 307 into the socket 306, and then start the drive motor 8. The drive motor 8 starts to drive the rotating rod 6 to rotate. Under the transmission action of the belt, the two driven rods 5 will also start to rotate. The rotation of the driven rod 5 drives the two-way threaded rod 4 to rotate. The rotation of the two-way threaded rod 4 drives the two threaded sliders 301 to slide toward each other inside the slide groove 2. The sliding of the threaded slider 301 drives the two clamping claws 303 to approach each other, thereby clamping pipes of different diameters to keep the pipes stable and avoid the shaking of the pipes affecting the welding operation.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
