Description

Technical Field

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

[0002] At present, pipelines are devices connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. They are mostly used in metallurgical mining machinery, chemical machinery and other fields.

[0003] For example, a Chinese utility model patent with announcement number CN217019258U discloses a pipeline welding and fixing device. Although the above-mentioned prior art improves the work efficiency of workshop engineering equipment personnel, it will not cause welding skewness, holes and the like after welding, thereby improving the welding quality. However, pipeline welding usually involves welding two pipelines together. Before welding, the two pipelines need to be clamped and fixed, usually with bolts and nuts or clamping equipment. In this way, not only do the two sections of the pipeline need to be clamped and fixed separately each time, but the clamping and fixing also need to be cancelled after the welding is completed. In this way, one welding is equivalent to four clamping and disassembly operations, which wastes a lot of welding time. Therefore, it is necessary to design a pipeline welding and fixing device that can quickly fix and clamp the welded pipeline and release the clamping. Utility Model Content

[0004] In order to solve the technical problem that the pipe fixing and releasing operations are relatively complicated when welding the pipe, the utility model provides a pipe welding fixing device.

[0005] The utility model is implemented by the following technical scheme: a pipeline welding and fixing device, including a welding table, one side of the welding table is provided with two clamping assemblies for clamping and fixing the pipeline, one side of the two clamping assemblies is provided with a synchronization assembly that allows the two clamping assemblies to be opened and closed and locked at the same time, and the clamping assembly includes a support block fixedly installed on one side of the welding table, a first clamping plate fixedly installed on one side of the support block, and a second clamping plate rotatably installed on one side of the first clamping plate.

[0006] Through the above technical solution, when welding the pipeline, the two clamping components can be locked or unlocked synchronously by simply rotating the synchronization component.

[0007] As a further improvement of the above solution, the two first clamping plates and the two second clamping plates are both arranged in a semicircular ring shape.

[0008] Through the above technical solution, the semicircular ring shape can better clamp the pipe.

[0009] As a further improvement of the above scheme, sliding grooves are provided on the inner walls of the two first clamping plates and the two second clamping plates, and a sliding bar is slidably fitted inside each sliding groove, and a rubber plate arranged in a semicircular ring shape is fixedly installed on one side of each sliding bar.

[0010] Through the above technical solution, the rubber sheet can be replaced and can be better adapted and clamped to the pipeline.

[0011] As a further improvement of the above scheme, a fixed plate is fixedly installed on one side of the two first clamping plates and the two second clamping plates, and the synchronization component includes an adjustment rod arranged on one side of the welding table, threaded rods fixedly installed at both ends of the adjustment rod, and a limit block threadedly sleeved on each threaded rod, and a fixing groove adapted to the adjacent fixed plate is opened on one side of each limit block.

[0012] Through the above technical solution, the rotation of the threaded rod will cause the limit block to move, thereby fixing or releasing the two fixing plates.

[0013] As a further improvement of the above solution, a movable groove is opened on one side of the two support blocks, a sliding block is slidably matched inside each movable groove, and each sliding block is fixedly installed with an adjacent limit block.

[0014] Through the above technical solution, the sliding block cooperates with the moving groove to prevent the limiting block from rotating and deviating when moving.

[0015] As a further improvement of the above solution, one end of each of the two threaded rods is rotatably mounted with a support plate fixedly mounted to an adjacent support block.

[0016] Through the above technical solution, the support plate can provide support to one end of the threaded rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a clamping assembly and a synchronization assembly. When welding a pipeline, the two clamping assemblies can be released from the fixed locking effect by rotating the synchronization assembly, so that the pipeline can be placed in the clamping assembly. Then, the synchronization assembly can be rotated in the opposite direction to fix and lock the two clamping assemblies together, preventing the clamping assemblies from loosening during welding. This arrangement allows the clamping assemblies to be quickly locked and unlocked synchronously and can also realize rapid replacement of the welding pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A pipeline welding and fixing device of the present embodiment includes a welding platform 1, and one side of the welding platform 1 is provided with two clamping assemblies for clamping and fixing the pipeline. One side of the two clamping assemblies is provided with a synchronization assembly that allows the two clamping assemblies to be opened and closed and locked at the same time. The clamping assembly includes a support block 201 fixedly installed on one side of the welding platform 1, a first clamping plate 202 fixedly installed on one side of the support block 201, and a second clamping plate 203 rotatably installed on one side of the first clamping plate 202. The two first clamping plates 202 and the two second clamping plates 203 are both arranged in a semicircular ring shape. Sliding grooves are provided on the inner walls of the two first clamping plates 202 and the two second clamping plates 203. The interior of each sliding groove is slidably matched with a sliding bar 4. A rubber plate 5 arranged in a semicircular ring shape is fixedly installed on one side of each sliding bar 4. When welding the pipeline, the two clamping assemblies can be locked or unlocked synchronously by rotating the synchronization assembly. The rubber plate 5 can be replaced to better adapt to the clamping of the pipeline.

[0026] Combination Figure 1-Figure 3, a fixed plate 6 is fixedly installed on one side of the two first clamping plates 202 and the two second clamping plates 203, and a synchronization component includes an adjustment rod 301 arranged on one side of the welding table 1, a threaded rod 302 fixedly installed at both ends of the adjustment rod 301, and a limit block 303 threadedly sleeved on each threaded rod 302, and a fixed groove matched with an adjacent fixed plate 6 is opened on one side of each limit block 303, and a movable groove is opened on one side of the two support blocks 201, and a sliding block 7 is slidably matched inside each movable groove, and each sliding block 7 is fixedly installed with an adjacent limit block 303, and a support plate 8 fixedly installed with an adjacent support block 201 is rotatably installed at one end of the two threaded rods 302, and the rotation of the threaded rod 302 will allow the limit block 303 to move, thereby fixing or releasing the two fixed plates 6, and the sliding block 7 cooperates with the movable groove to prevent the limit block 303 from rotating and deviating when moving.

[0027] The implementation principle of a pipeline welding fixing device in the embodiment of the present application is as follows: when welding the pipeline, the adjusting rod 301 is pulled upward by hand, so that the threaded rods 302 at both ends will rotate, and the rotation of the threaded rod 302 will cause the limit block 303 to move, so that the two fixing plates 6 will be out of the fixing groove of the limit block 303, so that the two second clamping plates 203 can be opened, and the rubber plate 5 is pulled out for replacement according to the size of the pipeline. After the replacement is completed and the pipeline is clamped, the adjusting rod 301 is then pressed downward, which will cause the threaded rod 302 to rotate in the opposite direction, so that the limit block 303 will move again, thereby inserting the two fixing plates 6 into the fixing groove of the limit block 303. After the two fixing plates 6 are fixed, the second clamping plate 203 will be restricted and cannot be opened. After the pipeline is clamped and fixed, welding can be performed, and only one step is required to open or lock the clamping assembly. This arrangement allows the clamping assembly to be quickly and synchronously locked and unlocked, and can also achieve rapid replacement of the welded pipeline.

[0028] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
