Order is provided with drive mechanism 8, braking mechanism 10 and walking mechanism 11.Described tension mechanism 5 side is arranged on forebay 1
On, the opposite side of this tension mechanism 5 is arranged in middle frame 6, and the side of this floating spring mechanism 7 is connected with middle frame 6, should
The opposite side of floating spring mechanism 7 is connected with afer bay 9.Described gas tank 12 is connected with afer bay 9, described welding unit
4 and described rotating disk mechanism 3 be arranged in this tension mechanism 5.
Referring to shown in Fig. 3, Fig. 4, described welding unit 4 is by wire-feed motor 41, many groups compound electric cable 42, multiple weldering
Gun case 43, multiple arc welding gun head 44, multiple arc welding gun head guiding mechanism 45, multiple arc welding gun head lifting cylinder 46 form, and are sent by described
Silk machine 41 removes and is arranged on from welding unit 4 in forebay 1.Described multiple welding gun boxes 43 are arranged in rotating disk mechanism 3,
The present embodiment is provided with 42,6 welding gun boxes of 6 compound electric cables, 44,6 arc welding gun head guiding mechanisms of 43,6 arc welding gun heads 45,6
Arc welding gun head lifting cylinder 46.This each welding gun box 43 includes 45, the weldering of 44, arc welding gun head guiding mechanism of an arc welding gun head
Rifle head lifting cylinder 46, this wire-feed motor 41 is connected by compound electric cable 42 with this arc welding gun head 44, described weldering rob 44 with
This arc welding gun head guiding mechanism 45 one end is connected, and the other end of this arc welding gun head guiding mechanism 45 is connected with described welding gun box 43.
Owing to this wire-feed motor 41 removes from welding unit 4, eliminate rise block 514 and the push rod of compound electric cable 42 and tension mechanism 5
The friction of 513, adds the service life of compound electric cable 42, meanwhile, simplifies the structure of welding unit, and probability of failure subtracts
Few so that welding unit 4 overall dimensions reduces, and reduces the distance that two rows are risen between block, thus preferably treats welded tube by first
The mouth of pipe school of road 14 and the second pipeline 15 to be welded is justified and is grouping.
Referring to shown in Figure 11, described forebay 1 is laid with 3 set line-up clamp 13, each line-up clamp 13 is by cylinder
Bearing 131, line-up clamp cylinder 132, connecting rod 133, locating piece 134, rear pressure head 135, positioning reference plane 136, front pressure head 137 groups
Become.Wherein, described cylinder saddle 131 one end is arranged on fore-stock 1, and the other end of this cylinder saddle 131 is right with described
One end of mouthpart cylinder 132 connects, and the other end of this line-up clamp cylinder 132 is connected with locating piece 134, described connecting rod 133 and
This locating piece 134 connects, pressure head 137 before the front upper surface of this locating piece 134 is provided with, in the face, posterior end of this locating piece 134
Pressing pressure head 135 after being provided with, described positioning reference plane 136 contacts with this first pressure head 135 outer surface.
After 3 line-up clamp cylinders 132 prop up 3 respectively, pressure head 135 contacts with positioning reference plane 136, pressure head after making 3
With in a plane, and the planes overlapping at now 3 front pressure heads 137 and all arc welding gun head 44 places, such guarantee welds
Rifle head 44 could overlap with the mouth of pipe 16 to be welded when with rotating disk 36 rotating welding.First by before internal welding machine during actually used
The first half of frame 1 and tension mechanism 5 exposes the second pipeline 15 to be welded, props up line-up clamp cylinder 132 so that pressure head after 3
The surface of 135 overlaps with 3 positioning reference planes 136 respectively；Start drive mechanism 8 so that internal welding machine in pipeline to be welded backward
Fang Yidong, until 3 front pressure heads 137 contact with the mouth of pipe 16 to be welded, the now surface of pressure head 135 and positioning reference plane 136 after 3
Overlapping, 3 front pressure heads 137 contact with the mouth of pipe 16 to be welded, prop up rapidly the tension mechanism 5 block 514 that rises in the second welded tube road 15,
Make its stretching inner-walls of duct, unclamp drive mechanism 8 and line-up clamp cylinder 132, complete boil on the nape opposite the mouth.But owing to site operation environment compares
Complexity, the surface of pressure head 135 and positioning reference plane or 3 front pressure heads 137 and the mouth of pipe to be welded after 3 during carrying out boil on the nape opposite the mouth
