As shown in Fig. 7, Figure 13, there is wire guide plate 34 at the second movable plate 935 back to the connection of location-plate 931 1 side surface, lead Offering waist type groove on line plate 34, the welding wire 92 in wire spool 94 wears the waist type groove on wire guide plate 34, wears into weldering the most again In joint 91, also setting up the hard tube 36 being connected to plumb joint 91 between plumb joint 91 and wire guide plate 34, hard tube 36 is in vertically setting Putting, it primarily serves the effect of protection welding wire 92, and hard tube 36 is connected by a straight-bar 39 with the second movable plate 935 surface, welding wire 92 wear and enter back into plumb joint 91 into after hard tube 36, and plumb joint 91 is positioned at the surface of axostylus axostyle 32.

Concrete welding process: when needing the straight steel pipe that steel pipe is column type of welding, steel pipe is placed on conveyer device 4 Roller tray 41 on, during placement, the gap of steel pipe is upward, is rotated by driven by motor screw mandrel so that roller tray 41 is on base 42 Rolling, direction motion on front side of main frame 1, regulation master cylinder 3 controls crossbeam 15 and slides up and down so that the torr below crossbeam 15 Frame group 7 is in an applicable height, and steel pipe enters in main frame 1, and bracket 71 is positioned at the outside of steel pipe, bottom bracket 72 In the inner side of steel pipe, stop roller tray 41 and move, control master cylinder 3 and move so that card and sheet 23 in bracket 71 embed steel In pipe seam gap, roll shaft 22 abuts the outside in steel pipe gap；Articulated slab 242 is driven to move up and down by hydraulic cylinder 25 again so that under Bracket 72 can rotate around the bearing pin of fixed plate 241 with bottom bracket 72 tail end, and then makes pallet 31 in the vertical direction Position change, make axostylus axostyle 32 abut inside steel pipe gap；In order to make axostylus axostyle 32 more fit inside steel pipe gap, logical Cross Rotary tray 31 base plate 311 change axostylus axostyle 32 angle of inclination (now be typically allow axostylus axostyle 32 be in level) or It is to make axostylus axostyle 32 can be subjected to displacement toward the steel pipe left and right sides to reach to carry and do axostylus axostyle 32 and steel pipe gap by movable panel 312 The purpose of inner side laminating degree；Afterwards according to different diameter of steel tube, regulation pressure roller head 63 makes it rotate around first connecting rod 631, reaches To the purpose of pressure roller head 63 altitude mixture control, then it is flexible to control side cylinder 61 so that the abutment roller 635 on pressure roller head 63 abuts steel pipe The left and right sides；By control and regulation assembly 93 so that plumb joint 91 is connected to the outside in steel pipe gap, restart motor and drive Roller tray 41, welding mechanism 9 brings into operation, and welding fluid flows in the gap between steel pipe, closes steel pipe gap by axostylus axostyle 32 Inner side, when steel pipe moves forward, axostylus axostyle 32 is connected to the inner side in steel pipe gap all the time, and roll shaft 22 abuts outside steel pipe gap all the time Side, card and sheet 23 are embedded in steel pipe gap, all the time until whole steel-pipe welding completes.

When the steel pipe needing welding is tapered or during circular platform type, i.e. when steel pipe is placed on roller tray 41, steel pipe stitches Gap is inclined to be set up, regulation in the motion mode of conveyer device 4, the fixed form of left and right press roll component 6, welding mechanism 9 As the regulative mode of assembly 93, the regulative mode of pallet 31 all keep, be in place of difference to need to regulate connecting rod group 21 with Change the angle of inclination of bracket 71 so that the gap keeping parallelism that bracket 71 is to be welded with steel pipe, thus ensure card and sheet 23 can embed in gap, roll shaft 22 can abut outside steel pipe gap, is that Rotary tray 31 base plate 311 changes in place of another difference Become the angle of inclination of axostylus axostyle 32 so that the gap keeping parallelism that axostylus axostyle 32 can be to be welded with steel pipe, when conveyer device 4 drives steel When pipe moves forward, owing to steel pipe gap is inclined, so system control box 10 needs to control master cylinder 3 continues upward shifting Dynamic, to ensure that roll shaft 22, card and sheet 23, axostylus axostyle 32 in bracket 71 and bottom bracket 72 all keep original state with steel pipe Position relationship.

The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
