[0003] The equipment pipelines on the coal washing equipment are generally installed in a flange connection manner, so it is necessary to weld a flange at the end of the equipment pipeline. When the two pipelines are flange-connected, the flanges on both sides need to be precisely docked. Therefore, in the process of welding the flange at the end of the equipment pipeline, the pipeline and the flange need to be precisely docked.

[0004] If the length of the pipeline is short, it is convenient to place it upright and connect it, and then it is convenient to rotate the pipeline, so that the connection between the pipeline and the flange can be welded 360 degrees. However, if the pipeline is long, it is necessary to use lifting equipment in conjunction with it. On the one hand, the lifting equipment needs to be repeatedly used for installation and disassembly during the lifting of the pipeline, which is more cumbersome. On the other hand, the pipeline is prone to movement during the lifting process, resulting in the inability to coincide with the central axis of the pipeline and the flange, which may cause the connection between the pipeline and the flange to be offset. At the same time, the hoisted pipeline is not convenient to rotate, and welding equipment is required to surround the pipeline for welding, which is more cumbersome.

[0023] The embodiment of the present application provides an electric flange welding precision positioning device for coal washing equipment, which solves the problem that if the pipeline is long, it needs to be used with a lifting device. On the one hand, the lifting device needs to be repeatedly used for installation and disassembly during the lifting process of the pipeline, which is relatively cumbersome. On the other hand, the pipeline is prone to movement during the lifting process, causing the central axis of the pipeline and the flange to be unable to coincide, thereby causing the connection between the pipeline and the flange to be offset. At the same time, it is inconvenient to rotate the hoisted pipeline, thereby requiring welding equipment to surround the pipeline for welding, which is relatively cumbersome. After the equipment pipeline positioning unit 3 positions the equipment pipeline body 5, the flange body 6 is placed on the side of the flange positioning unit 2, and the flange positioning unit 2 is used to position the flange body 6. Because the axis lines of the flange positioning unit 2 and the equipment pipeline positioning unit 3 overlap, the axis lines of the equipment pipeline body 5 and the flange body 6 can be aligned. At this time, the flange positioning unit 2 and the flange body 6 are driven by the driving unit 7 to move until the flange body 6 contacts the end of the equipment pipeline body 5, thereby achieving the effect of precise docking and positioning.

After the equipment pipeline positioning unit 3 positions the equipment pipeline main body 5, the flange body 6 is placed on the side of the flange positioning unit 2, and the flange positioning unit 2 is used to position the flange body 6. Since the axial center lines of the flange positioning unit 2 and the equipment pipeline positioning unit 3 overlap, the axial center lines of the equipment pipeline main body 5 and the flange body 6 can be aligned. At this time, the flange positioning unit 2 and the flange body 6 are driven by the driving unit 7 to move until the flange body 6 contacts the end of the equipment pipeline main body 5, thereby achieving the effect of precise docking and positioning; At this time, the connection between the flange body 6 and the equipment pipeline body 5 is welded, so that the flange body 6 and the equipment pipeline body 5 are partially welded, and then the positioning rotation unit 4 is turned on to drive the equipment pipeline body 5 to rotate relative to the equipment pipeline positioning unit 3, and the flange body 6 is rotated relative to the flange positioning unit 2, so as to facilitate the 360-degree welding of the connection between the flange body 6 and the equipment pipeline body 5.

When the multiple positioning wheels 25 move outward, the flange body 6 can be placed between the multiple positioning wheels 25, and then the flange body 6 can be clamped when the multiple positioning wheels 25 move inward. Since the positioning wheels 25 are rotatably arranged on the side of the end of the first connecting bar 24, the flange body 6 can rotate relative to the multiple positioning wheels 25 when it rotates.

[0041] When the first driving motor 451 is working, its output end drives the spline shaft 454 to rotate, thereby causing the third bevel gear 459 to rotate accordingly. Since the second bevel gear 458 and the third bevel gear 459 are meshed and connected, the transmission shaft 455 is rotated accordingly, and then the first bevel gear 457 at the top of the transmission shaft 455 drives the rotating shaft 456 inside the positioning rubber wheel 44 to rotate accordingly, thereby driving the positioning rubber wheel 44 to rotate; At the same time, during the lateral movement of the moving seat 42, it can drive the second transmission box 453 to move accordingly, and drive the first transmission box 452 to move through the connecting block 4521, and the transmission shaft 455 between the first transmission box 452 and the second transmission box 453 can move accordingly.
