Description

Technical Field

[0001] The present invention relates to an auxiliary docking device, specifically an auxiliary docking device for the welding and assembly of high-neck flanges, belonging to the technical field of flange auxiliary docking. Background Technique

[0002] The high-neck flange, also known as the high-neck butt-welding flange, is a pipeline connection component commonly used in industries such as boiler pressure vessels, petroleum, chemical engineering, shipbuilding, pharmaceuticals, metallurgy, machinery, and food processing. Due to its structural characteristics, the high-neck flange has a relatively high neck height, thus having relatively high stiffness and load-bearing capacity, and is suitable for high-pressure and high-temperature environments. The welding and assembly of high-neck flanges is a professional technical process, mainly through welding to connect and fix the high-neck flange and the pipeline. The high-neck flange welding technology has extensive applications in fields such as petrochemical engineering, urban water supply, and hydropower systems.

[0003] A Chinese patent with the patent name "A High-Neck Flange Docking and Welding Machine" (publication number CN211614692U) discloses a high-neck flange docking technology. By setting a double welding frame and a double adjustment wheel assembly, it can conveniently perform welding work on the high-neck flanges at both ends of a straight pipe. Driven by the cylindrical adjustment rollers, the workpiece can be driven to rotate accurately and evenly, ensuring good weld quality. Moreover, both the horizontal movement and the vertical movement are realized through a lead screw and slide rail structure, with stable operation and convenient adjustment, reducing the labor intensity of workers. However, although this docking and welding machine does not require manual docking and can drive the workpiece to rotate, it is only applicable to the docking operation at both ends of the pipeline and cannot meet the docking requirements at different angles, such as 90°, 45°, or 60° docking operations.

[0004] A Chinese patent with the patent name "A Special Equipment for the Ring Welding of Steel Pipes and High-Neck Flanges" (patent number CN201310058069.5) discloses a flange ring welding technology, which can weld the inner and outer sides of the steel pipe in two times to form two inner and outer ring welds. When welding the inside of the steel pipe, the welding head extends into the steel pipe from the flange end, and the welding process is completely automated, with high welding production efficiency and stable welding quality. However, this equipment still has the problem of only being able to achieve the docking at the ends of the pipeline and cannot meet the docking requirements at different angles on the side. Therefore, an auxiliary docking device for the welding and assembly of high-neck flanges is proposed. Summary of the Invention

The rotating worm 402 drives the entire first clamp seat 331 to rotate by using the worm gear ring 403, so as to perform rotational adjustment on the pipeline according to actual needs.

[0036] When it is necessary to fix the high-neck flange, the output shaft of the fifth motor 606 drives the second threaded disk 603 to rotate. The rotating second threaded disk 603 drives the second jaw 604 and the stud 605 to move synchronously by means of the thread, so as to adjust the stud 605 to a suitable position according to the position of the flange holes on the high-neck flange. Then, the high-neck flange is moved to make the stud 605 penetrate the flange holes, and then the high-neck flange is limited on the second jaw 604 and the stud 605 by means of the thread. Then, the output shaft of the fifth motor 606 drives the second threaded disk 603 to rotate, so as to drive the second jaw 604 and the stud 605 to move again by means of the second threaded disk 603, so that the outer wall of the stud 605 is fully attached to the inner wall of the flange hole, ensuring concentric fixing and limiting of the high-neck flange. Then, by further installing nuts, the fixing operation of the high-neck flange is completed. The high-neck flange can also be directly inserted into the second clamping seat 602, and the outer wall of the high-neck flange is clamped and fixed by the moving second jaw 604. Although this operation is relatively simple, it cannot effectively control the fixing accuracy of the high-neck flange, and problems such as inclination and deviation are likely to occur.

[0037] When it is necessary to dock the high-neck flange to the end of the pipeline, the output shaft of the first motor 201 drives the first lead screw 202 to rotate. The rotating first lead screw 202 drives the first threaded slider 203 to move by means of the thread. The moving first threaded slider 203 drives the overall movement of the pipe limiting frame 301 in cooperation with the pipe pushing plate 204, so as to adjust the position of the pipeline according to actual needs. Then, the output shaft of the fourth motor 501 drives the second lead screw 502 to rotate. The rotating second lead screw 502 drives the flange pushing plate 504 to move by means of the thread in cooperation with the second threaded block 503. The moving flange pushing plate 504 drives the overall movement of the flange limiting frame 601. The moving flange limiting frame 601 drives the high-neck flange to move towards one end of the pipeline, so as to dock the high-neck flange to one end of the pipeline.

[0038] When it is necessary to butt the high-neck flange to the butt hole position on the side of the pipeline, first determine the required butt angle of the high-neck flange according to the actual requirements or the direction of the butt hole; such as 90°, 30°, 45° or 60°, and then start the corresponding electromagnet 704 to work according to the determined angle. The working electromagnet 704 generates magnetic force to attract the iron core pin shaft 705, so that the bottom of the iron core pin shaft 705 comes out of the indexing plate seat 701 and fits with the surface of the adjusting support frame 102. Then, the piston rod of the hydraulic cylinder 802 drives the connecting collar 803 to move. The moving connecting collar 803 cooperates with the arc-shaped plate frame 804 to drive the overall movement of the adjusting support frame 102. The moving adjusting support frame 102 drives the positioning hole 703 and the roller 92 to move. The moving roller 92 slides in the arc-shaped guide groove 93 to guide the adjusting support frame 102, and the friction between the adjusting support frame 102 and the guide plate 103 can be reduced by the arranged roller 92. When the positioning hole 703 adapted to the iron core pin shaft 705 moves to the designated position, the electromagnet 704 uses magnetic force to attract the top of the iron core pin shaft 705, so that the bottom of the iron core pin shaft 705 slides into the positioning hole 703 and drives the spring 706 to stretch at the same time. The iron core pin shaft 705 inserted into the positioning hole 703 locks the adjusting support frame 102, so as to quickly adjust the adjusting support frame 102 to an appropriate angle. Then, the docking pushing mechanism 2 drives the synchronous clamping assembly 3 to drive the pipeline to adjust the position. When the pipeline position adjustment is completed, the auxiliary pushing mechanism 5 drives the flange clamping mechanism 6 to drive the high-neck flange to dock with the hole on the side of the pipeline, ensuring the stability between the high-neck flange and the pipeline during side docking.
