Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding equipment, in particular to a pipeline connection welding device. Background Art

[0002] At present, a pipeline refers to a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids or fluids with solid particles. During the installation process of pipelines with relatively short lengths, in order to ensure the tightness and firmness of pipeline connections, two sections of pipelines are usually welded. Since pipeline welding is frequently used, it is necessary to optimize pipeline welding.

[0003] A welding device for pipelines is disclosed in the Chinese utility model patent with the publication number CN220112663U. In the above-mentioned prior art, although the tight fit between the ends of two sections of pipelines before welding is ensured, and thus the welding quality of the two sections of pipelines after welding is guaranteed, only two sections of pipelines can be welded each time. After each welding is completed, the pipelines need to be removed from the fixing device, and then new two sections need to be installed and fixed for movement. Such a replacement method and the fact that only two sections of pipelines can be welded each time will waste a lot of time and affect the welding efficiency. Therefore, it is necessary to design a pipeline welding device that can quickly replace welded pipelines. Summary of the Utility Model

[0004] To solve the technical problem that the fixing and disassembly of pipelines during welding are troublesome and time-consuming, the utility model provides a pipeline connection welding device.

[0005] The utility model is realized by the following technical solutions: A pipeline connection welding device includes two support plates. A support column is rotatably installed between the two support plates. A plurality of mounting disks are fixedly sleeved on the support column. A plurality of clamping components capable of clamping and fixing the pipeline and facilitating replacement are arranged on the circumferential surface of each mounting disk. A fixing component for fixing the support column to prevent rotation is arranged on one side of the support column. A plurality of limiting grooves are formed on the circumferential surface of each mounting disk.

[0006] Through the above technical solutions, the clamping component can be used to clamp the pipeline in advance, and during the installation and disassembly of the pipeline, the clamping component can be used for quick installation and disassembly.

[0007] As a further improvement of the above solution, the clamping component includes a sliding block sliding inside the limiting groove, a first clamping plate fixedly installed on one side of the sliding block, and a second clamping plate rotatably installed on one side of the first clamping plate.

[0008] Through the above technical solutions, the pipeline can be fixed in advance by the first clamping plate and the second clamping plate, and the pipeline can be quickly installed and disassembled in cooperation with the sliding block.

[0009] As a further improvement of the above solution, a first fixing plate is fixedly installed on one side of each of the first clamping plates, a second fixing plate is fixedly installed on one side of each of the second clamping plates, a threaded column is provided on one side of each of the second fixing plates, one end of each of the threaded columns penetrates through the adjacent second fixing plate and is in threaded cooperation with the adjacent first fixing plate, and a rotating block is fixedly installed at the other end of each of the threaded columns.

[0010] Through the above technical solution, when the threaded column rotates, the first fixing plate and the second fixing plate will be limited and fixed, so that the first clamping plate and the second clamping plate are fixed.

[0011] As a further improvement of the above solution, the fixing component includes a rubber block provided on one side of the support column, a pressing rod fixedly installed on one side of the rubber block, and a pushing rod fixedly installed at both ends of the pressing rod.

[0012] Through the above technical solution, when the rubber block presses the support column, the support column will be fixed without external force.

[0013] As a further improvement of the above solution, a rotating column is rotatably fitted on each of the pushing rods, and a limiting plate is rotatably installed at both ends of each of the rotating columns.

[0014] Through the above technical solution, the rotating column and the limiting plate will cause one end of the pushing rod to be lifted.

[0015] As a further improvement of the above solution, each of the pushing rods is arranged in a "√" shape.

[0016] Through the above technical solution, when one end of the pushing rod is pressed down, the other end will be lifted.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing an installation disc, a clamping component and a fixing component, when welding pipes, the clamping component can be used to clamp and fix multiple pipes in advance. When replacing the pipes, the clamping component can be directly slid and quickly replaced. The fixing component can be used to prevent the installation disc from rotating during welding. Such a setting can not only make the replacement of the pipes more convenient and fast, but also install multiple pipes on the installation disc, avoiding the need to replace the pipes each time a pipe is welded.

[0024] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] Please refer to Figures 1 - 3 , A pipeline connection and welding device in this embodiment includes two support plates 1. A support column 2 is rotatably installed between the two support plates 1. A plurality of mounting disks 3 are fixedly sleeved on the support column 2. A plurality of clamping assemblies capable of clamping and fixing the pipeline and facilitating replacement are provided on the circumferential surface of each mounting disk 3. A fixing assembly for fixing the support column 2 to prevent rotation is provided on one side of the support column 2. A plurality of limiting grooves are opened on the circumferential surface of each mounting disk 3. The pipeline can be clamped in advance by the clamping assembly. When installing and disassembling the pipeline, the clamping assembly can be used for quick installation and disassembly.

[0026] Refer to Figures 1 - 3 , The clamping assembly includes a sliding block 401 sliding inside the limiting groove, a first clamping plate 402 fixedly installed on one side of the sliding block 401, and a second clamping plate 403 rotatably installed on one side of the first clamping plate 402. A first fixing plate 6 is fixedly installed on one side of each first clamping plate 402. A second fixing plate 7 is fixedly installed on one side of each second clamping plate 403. A threaded column 8 is provided on one side of each second fixing plate 7. One end of each threaded column 8 penetrates through the adjacent second fixing plate 7 and is in threaded cooperation with the adjacent first fixing plate 6. A rotating block is fixedly installed at the other end of each threaded column 8. The pipeline is fixed in advance by the first clamping plate 402 and the second clamping plate 403. The sliding block 401 can be used for quick installation and disassembly of the pipeline. When the threaded column 8 rotates, the first fixing plate 6 and the second fixing plate 7 will be limited and fixed, so that the first clamping plate 402 and the second clamping plate 403 are fixed.

[0027] Refer to Figure 1, the fixing component includes a rubber block 501 disposed on one side of the support column 2, a pressing rod 502 fixedly installed on one side of the rubber block 501, and push rods 503 fixedly installed at both ends of the pressing rod 502. A rotating column 9 is rotatably fitted on each push rod 503. Limiting plates 10 are rotatably installed at both ends of each rotating column 9. Each push rod 503 is arranged in a "√" shape. When the rotating column 9 cooperates with the limiting plate 10, one end of the push rod 503 will be lifted. When the rubber block 501 presses against the support column 2, the support column 2 will be fixed without external force.

[0028] The implementation principle of a pipeline connection welding device in the embodiment of the present application is as follows: All pipelines to be welded are clamped in advance using the first clamping plate 402 and the second clamping plate 403. Rotate the threaded column 8 to fix the first fixing plate 6 and the second fixing plate 7. In this way, the first clamping plate 402 and the second clamping plate 403 will also be fixed, and all pipelines are clamped and fixed in advance. This fixing can be carried out before welding to avoid affecting the welding time. When installing the pipelines to be welded, insert the sliding block 401 into the limiting groove of the mounting disc 3. In this way, when the limiting grooves of both mounting discs 3 are inserted with the sliding block 401, every two pipelines can be fitted together. After welding is completed, only need to slide the entire pipeline to remove the two sliding blocks 401 and replace them with the ones prepared in advance to achieve rapid replacement of the pipelines to be welded. Moreover, there are multiple limiting grooves on the mounting disc 3, that is, multiple groups of pipelines can be welded together and removed uniformly after welding, instead of replacing one pipeline after welding one. And the cooperation between the sliding block 401 and the limiting groove is relatively tight, and a certain pushing force is required to move the sliding block 401 inside the limiting groove to avoid the sliding block 401 driving the pipeline to move by itself during welding. Because the contact point during welding is very small and there is little external force to push the sliding block 401. And during welding, when the welder presses the push rod 503, the rubber block 501 can be lifted, so that the support column 2 will not rotate, avoiding affecting welding. Such a setting can not only make the replacement of pipelines more convenient and fast, but also install multiple pipelines on the mounting disc 3, avoiding the need to replace the pipeline each time after welding one pipeline.

[0029] The above implementation manners are only the preferred implementation manners of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
