Description

Technical Field

[0001] The utility model relates to the technical field of large-scale pipeline welding, in particular to a system for improving the welding efficiency of large-scale pipelines. Background Art

[0002] The production of large pipelines requires more welding surfaces due to their large size, and welding is required inside and outside, which requires a large amount of work. Due to external factors such as the site, several sections of pipelines need to be butt-welded and then hoisted and installed at one time.

[0003] The current welding method is that workers use scaffolding to build a welding platform, but the height of the scaffolding is too high. When workers stand on it to weld, there are safety hazards. After welding for a certain distance, workers need to move the scaffolding, which is time-consuming and labor-intensive, and has low work efficiency. Utility Model Content

[0004] Aiming at the problem that current welding modes and methods cannot meet the needs of on-site production, the utility model provides a system for improving the welding efficiency of large pipelines, including a gantry, a welding platform and a roller frame.

[0005] The roller frame is set under the gantry to place and roll the pipe to be welded, so as to facilitate the adjustment of the position to be welded during the welding process. The gantry is provided with a first track, which is fixed to the ground so that the gantry can move along the first track, and the direction of the first track is the same as the length direction of the pipe. The welding platform is connected to the gantry to increase the working height of the welder.

[0006] When using this system, first place the pipe to be welded on the roller frame, then the worker climbs onto the welding platform, and uses the height of the welding platform to stand on the welding platform to weld at the position to be welded. The roller frame can be used to rotate the pipe to rotate other parts to a position suitable for the workers on the welding platform to weld. After a section of the pipe is welded, the gantry moves along the pipe and moves the welding platform to the next working position to weld the next section of the pipe.

[0007] In the case of large pipelines that need to be welded on site, the system can be assembled on site. The size of the gantry actually required can be determined based on the actual size of the pipeline, and a gantry of the appropriate size can be selected for assembly.

[0008] Furthermore, the welding platform includes a lifting mechanism, and the welding platform is connected to the gantry through the lifting mechanism, so that the height of the welding platform is adjustable. The height of the welding platform can be adjusted according to the size of the pipeline, making the use of the system more flexible.

[0009] Furthermore, the lifting mechanism is a hydraulic rod, a pneumatic rod or a screw-nut pair.

[0010] Furthermore, the welding platform includes a translation mechanism, which includes a second track, the direction of the second track is perpendicular to the direction of the first track, and the second track is fixed on the gantry, so that the welding platform can move along the second track. The welding platform can also move along the gantry, which makes it easier to adjust the position of the welding platform during welding operations.

[0011] Furthermore, the translation mechanism also includes a motor and a roller, and the roller is driven by the motor to move along the second track.

[0012] Furthermore, the welding platform also includes a guardrail to prevent personnel or tools from accidentally falling during operation.

[0013] The utility model uses a movable gantry, which is convenient for moving on the top of the pipeline. A person can stand on the welding platform to weld the pipeline interface, and the welding of the entire pipeline section can be completed by moving the gantry.

[0014] The utility model can also produce a gantry with a suitable height according to the diameter of the pipeline. The gantry can be moved back and forth to facilitate welding the outer surface of the pipeline. There is no need to use a scaffolding, and the gantry can be moved continuously, which significantly improves the welding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 , Figure 2 The system of this embodiment includes a gantry 1, a welding platform 2 and a roller frame 3.

[0021] The roller frame 3 is arranged under the gantry 1, and is used to place and roll the pipe 4 to be welded, so as to facilitate the adjustment of the position to be welded during the welding process. The gantry 1 is provided with a first track 5, and the first track 5 is fixed to the ground, so that the gantry 1 can move along the first track 5, and the direction of the first track 5 is the same as the length direction of the pipe 4. The welding platform 2 is connected to the gantry 1, and is used to increase the working height of the welder.

[0022] In this embodiment, the welding platform 2 preferably includes a lifting mechanism 6, and the lifting mechanism 6 can be a hydraulic rod, a pneumatic rod, or a screw nut pair. The welding platform 2 is connected to the gantry 1 through the lifting mechanism 6, so that the height of the welding platform 2 can be adjusted. According to the size of the pipeline 4, the height of the welding platform 2 can be adjusted, making the use of the system more flexible.

[0023] In this embodiment, the welding platform 2 preferably includes a translation mechanism, which includes a second track 7, the direction of the second track 7 is perpendicular to the direction of the first track 5, and the second track 7 is fixed on the gantry 1, so that the welding platform 2 can move along the second track 7. The welding platform 2 can also move along the gantry 1, which is more convenient for adjusting the position of the welding platform 2 during welding. The translation mechanism includes a motor and a roller, and the roller is driven by the motor to move along the second track 7.

[0024] Preferably, in this embodiment, the welding platform 2 also includes a guardrail 8 to prevent personnel or tools from accidentally falling during operation.

[0025] When using this system, first place the pipe 4 to be welded on the roller frame 3, and then use the lifting mechanism 6 and the translation mechanism to adjust the position of the welding platform 2 to facilitate subsequent welding operations. Then the staff climbs onto the welding platform 2, and uses the height of the welding platform 2 to stand on the welding platform 2 to weld the position to be welded. The roller frame 3 is equipped with a motor that can drive the roller to rotate, thereby driving the pipe 4 on it to rotate. After the welding of one part of the pipe 4 is completed, the pipe 4 is rotated by the roller frame 3, and the other parts to be welded are rotated to a position suitable for the welding of the staff on the welding platform 2 for welding operations. After a section of the pipe 4 is welded, the gantry 1 is moved along the pipe 4, and the welding platform 2 is moved to the next working position to weld the next section of the pipe 4.

[0026] In the case where large pipelines 4 need to be welded on site, the system can be assembled on site. The size of the gantry 1 actually required can be determined based on the actual size of the pipeline 4, and a gantry 1 of a suitable size can be selected for assembly.
