Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline welding and fixing, in particular to a pipeline welding butt assisting device. Background Art
[0002] At present, when welding pipelines, the pipelines are generally placed on the support plate, and the pipelines exert pressure on the support plate, and then the support plate exerts pressure on the telescopic support and the shock-absorbing spring. The vibration of the pipelines during the welding process is buffered by the telescopic support, the shock-absorbing spring and the connecting rod, thereby improving the safety and stability of the pipeline welding process. However, in actual operation, it is found that although the shock-absorbing spring can absorb the vibration of the pipeline to a certain extent, the vibration generated during the welding process will still cause the pipeline to vibrate to a certain extent, which is easy to cause a temporary misalignment at the end interface between the pipelines, thereby reducing the actual welding quality of the pipeline.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.
[0024] Example
[0025] Please refer to Figure 1 and Figure 2 , is a type of pipe welding butt joint auxiliary device, comprising two brackets symmetrically assembled on both sides, each bracket comprising two upright posts 1 perpendicular to the ground and a clamping plate 2 horizontally placed on the upright posts 1. At least one of the upright posts is provided with a scale mark 11.
[0026] Please refer to Figure 3 , 4 Combination Figure 1-2 The clamping plate 2 includes an upper clamping plate 21 and a lower clamping plate 22, wherein the lower clamping plate 22 is inserted into the column 1, and a through hole is provided in the lower clamping plate 22 for the column 1 to pass through. The lower surface of the upper clamping plate 21 is recessed upward to form a first upper half groove 211 and a second upper half groove 212, respectively, and the upper surface of the lower clamping plate 22 is recessed downward to form a first lower half groove 221 and a second lower half groove 222, respectively, wherein the first upper half groove 211 and the first lower half groove 221 have the same curvature, and are assembled together to form a first placement groove, the shape of which is adapted to the shape of the outer surface of the elbow 9 for placing the elbow 9. The second upper half groove 212 and the second lower half groove 222 are both straight grooves, and are assembled together to form a second placement groove, which is a straight groove for placing a straight pipe.
[0027] This embodiment takes the welded elbow 9 as an example, please refer to Figure 3 A telescopic push rod 5 is installed between the upper clamping plate 21 and the lower clamping plate 22. The telescopic push rod 5 is an electric push rod. The distance between the upper clamping plate 21 and the lower clamping plate 22 is adjusted by controlling the extension and contraction of the telescopic push rod 5, so that the bent pipe 9 can be clamped after being placed in the placement groove.
[0028] Please refer to Figure 3 Combination Figure 1-2 A mounting rod 6 is fixedly connected between the two upright posts 1 of the bracket near the top, and a first threaded hole with an internal thread is provided on the mounting rod 6, and a threaded rod 7 is inserted into the first threaded hole. The lower end of the threaded rod 7 is inserted into a lower clamping plate 22, and a second threaded hole with an internal thread is provided on the lower clamping plate 22 for threaded connection of the threaded rod 7. By rotating the threaded rod 7, the lower clamping plate 22 can be driven to move up and down relative to the mounting rod 6 and the upright post 1.
[0029] Please refer to Figure 1-2 At the lower position of the two symmetrically assembled brackets, the column 1 of each bracket is laterally fixedly connected with a cross bar 3, and the two opposite cross bars 3 are inserted into a hollow tube 4. The hollow tube 4 is respectively provided with positioning screw holes at the left and right ends. After the two cross bars 3 are adjusted to the preset position, the cross bars 3 are supported by screwing bolts 8 into the positioning screw holes to prevent them from sliding relative to the hollow tube 4, thereby realizing the lateral positioning and fixation of the two brackets.
[0030] When in use, the curved pipe 9 is placed in the first lower half groove 221 of the lower clamping plate 22, and then the electric telescopic push rod 5 is controlled to extend, at which time the upper clamping plate 21 can be driven to move downward, and as the upper clamping plate 21 moves downward, the lower curved pipe 9 can be clamped, and then the threaded rod 7 is held and rotated forward and backward, at which time the lower clamping plate 22, the upper clamping plate 21 and the curved pipe 9 can be driven to move up and down. Similarly, another group of clamped curved pipes 9 can be controlled to move up and down, and the up and down displacement of the two curved pipes 9 can be found by observing the scale lines 11. When the longitudinal positions of the two curved pipes 9 are determined, the two lower clamping plates 22 are then held and moved relatively, at which time the cross bars 3 of the left and right brackets can be driven to move relatively, and then the two curved pipes 9 can be driven to move relatively, and when the ports of the two curved pipes 9 are abutted together, the bolts 8 in the two positioning screw holes are tightened, and at this time the two cross bars 3 can be fixed in the hollow pipe 4, and then the ports of the two curved pipes 9 can be welded by an external welding machine. When welding a straight pipe, just clamp the straight pipe in the second placement groove. The operation is the same as clamping a bent pipe.
[0031] Place the pipe in a suitable placement slot, and clamp it by controlling the distance between the upper and lower clamps through the electric telescopic push rod. There will be no misalignment at the end interface between the pipes, which increases the stability of the pipe welding process and prevents the pipe from loosening during welding. In addition, the longitudinal displacement of the pipe can be accurately controlled by the threaded rod and the scale line, and the lateral displacement of the pipe can be controlled by the coordinated use of crossbars, hollow pipes, bolts and other components, which greatly improves the welding accuracy and welding quality during the pipe welding process.
