Description

Technical Field

[0001] The invention relates to an auxiliary docking device, in particular to an auxiliary docking device for high-neck flange welding assembly, and belongs to the technical field of flange auxiliary docking. Background Art

[0002] High neck flange, also known as high neck butt welding flange, is a pipe connection component commonly used in boiler pressure vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, stamping elbow, food and other industries. Due to its structural characteristics, the high neck flange has a high neck height, so it has high rigidity and load-bearing capacity, and is suitable for high pressure and high temperature environments. The welding assembly of high neck flange is a professional technical process, which mainly uses welding to connect and fix the high neck flange to the pipeline. High neck flange welding technology is widely used in petrochemical, urban water supply, hydropower systems and other fields.

[0003] The Chinese patent, entitled "A High-Neck Flange Butt Welding Machine" (publication number CN211614692U), discloses a high-neck flange butt welding technology. By providing a double welding frame and a double adjusting wheel assembly, the high-neck flanges at both ends of a straight pipe can be easily welded. Driven by the cylindrical adjusting roller, the workpiece can be driven to rotate accurately and evenly, so that the quality of the weld is well guaranteed. Both horizontal and vertical movements are achieved through a screw rod and a slide rail structure, with stable operation and easy adjustment, reducing the labor intensity of workers. However, although the butt welding machine does not require manual docking and can drive the workpiece to rotate, it is only suitable for docking operations at both ends of the pipe and cannot meet the docking requirements of different angles, such as 90°, 45° or 60°.

[0004] The Chinese patent, entitled "Specialized Equipment for Girth Welding of Steel Pipes and High-Neck Flanges" (patent number CN201310058069.5), discloses a flange girth welding technology that can weld the inside and outside of a steel pipe twice to form two inner and outer girth welds. When welding inside the steel pipe, the welding head extends into the steel pipe from the flange end. The welding process is fully automated, with high welding production efficiency and stable welding quality. However, the equipment still has the problem of only being able to achieve docking of the ends of the pipes and cannot meet the docking requirements of different angles on the sides. Therefore, an auxiliary docking equipment for high-neck flange welding assembly is proposed. Summary of the Invention

[0074] In one embodiment, the upper surface of the guide plate 103 is provided with two arc-shaped guide grooves 93 , and a plurality of rollers 92 are installed at the bottom of the adjustment support frame 102 , and the plurality of rollers 92 are respectively slidably connected to the inner side walls of the two arc-shaped guide grooves 93 ;

[0075] The roller 92 is driven to move in the arc guide groove 93 by the adjusting support frame 102 so that the arc guide groove 93 can be used to guide the movement of the adjusting support frame 102, and the roller 92 can be used to reduce the friction between the adjusting support frame 102 and the guide plate 103.

[0076] When the present invention is in operation: first, the pipe to be butted is inserted into the pipe limiting frame 301 , and then the distance the pipe extends from the other side of the pipe limiting frame 301 is adjusted according to actual needs.

[0077] When the pipeline is inserted and debugged, the second motor 302 is started, and the output shaft of the second motor 302 is used to drive the gear 306 to rotate. The rotating gear 306 drives the gear ring 305 and the inner tube 304 to rotate via the transmission chain 307. The rotating inner tube 304 drives the two first threaded disks 332 to rotate at the same time. The rotating first threaded disks 332 drive the first clamping jaws 333 to move synchronously via the threads. The synchronously moving first clamping jaws 333 are used to concentrically clamp the pipeline for subsequent concentric docking operations, thereby completing the fixing operation of the pipeline.

[0078] When it is necessary to adjust the pipeline rotation, such as adjusting the docking hole on the pipeline to a suitable position, the output shaft of the third motor 401 drives the worm 402 to rotate, and the rotating worm 402 uses the worm gear ring 403 to drive the first clamp 331 to rotate as a whole, so that the pipeline can be rotated and adjusted according to actual needs.

[0079] When the high-neck flange needs to be fixed, the second threaded disc 603 is driven to rotate by the output shaft of the fifth motor 606. The rotating second threaded disc 603 uses the thread to drive the second clamping jaw 604 and the stud 605 to move synchronously, so as to adjust the stud 605 to a suitable position according to the position of the flange hole on the high-neck flange. Then, the high-neck flange is moved so that the stud 605 passes through the flange hole, and then the high-neck flange is limited to the second clamping jaw 604 and the stud 605 by the thread. Then, the second threaded disc 603 is driven to rotate by the output shaft of the fifth motor 606. So that the second threaded disk 603 can be used to drive the second clamping jaw 604 and the stud 605 to move again, so that the outer wall of the stud 605 is fully fitted with the inner wall of the flange hole, ensuring the concentric fixation of the high-neck flange, and then completing the fixing operation of the high-neck flange by further installing the nut. The high-neck flange can also be directly inserted into the second clamping seat 602, and the outer wall of the high-neck flange can be clamped and fixed by the moving second clamping jaw 604. Although this operation is relatively simple, it cannot effectively control the fixing accuracy of the high-neck flange, and is prone to tilting and offset problems.

[0080] When the high-neck flange needs to be connected to the end of the pipeline, the first screw rod 202 is driven to rotate by the output shaft of the first motor 201, and the rotating first screw rod 202 drives the first threaded slider 203 to move by the thread, and the moving first threaded slider 203 cooperates with the pipe pushing plate 204 to drive the pipe limiting frame 301 to move as a whole, so as to adjust the position of the pipeline according to actual needs, and then the second screw rod 502 is driven to rotate by the output shaft of the fourth motor 501, and the rotating second screw rod 502 cooperates with the second threaded block 503 to drive the flange pushing plate 504 to move, and the moving flange pushing plate 504 drives the flange limiting frame 601 to move as a whole, and the moving flange limiting frame 601 drives the high-neck flange to move toward one end of the pipeline, so as to connect the high-neck flange to one end of the pipeline.

[0081] When it is necessary to dock the high-neck flange to the docking hole position on the side of the pipe, first determine the required docking angle of the high-neck flange according to actual needs or the direction of the docking hole; such as 90°30°, 45° or 60°, and then start the corresponding electromagnet 704 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 from the dividing plate seat 701 and fits with the surface of the adjustment support frame 102. Then, the piston rod of the hydraulic cylinder 802 drives the connecting ring 803 to move. The moving connecting ring 803 cooperates with the arc plate frame 804 to drive the adjustment support frame 102 to move as a whole. The moving adjustment support frame 102 drives the positioning hole 703 and the roller 92 to move. The moving roller 92 slides in the arc guide groove 93 to guide the adjustment support frame 102, and the friction between the adjustment support frame 102 and the guide plate 103 can be reduced by the provided roller 92. When the positioning hole 703 adapted to the core pin 705 moves to the specified position, the electromagnet 704 uses magnetic force to attract the top of the core pin 705, so that the bottom of the core pin 705 slides into the positioning hole 703 while driving the spring 706 to stretch. The core pin 705 inserted into the positioning hole 703 is used to lock the adjustment support frame 102 so that the adjustment support frame 102 can be quickly adjusted to a suitable angle. Then, the docking pushing mechanism 2 drives the synchronous clamping assembly 3 to drive the pipeline to adjust its position. When the pipeline position adjustment is completed, the auxiliary pushing mechanism 5 drives the flange clamping mechanism 6 to dock the high-neck flange with the hole on the side of the pipeline, ensuring the stability between the high-neck flange and the pipeline during side docking.
