  • command rod rear coupling 85 which is releasably connected to a command rod 86.
  • Command rod 86 is of a length such that it projects beyond the end of pipe 3 and includes at that end a command rod control panel (not shown) which can be used to control various functions of the machine and a command rod front coupling (not shown) which releasably connects the command rod to a supply of services eg. compressed air, battery charging current and welding current generators.

  • a wall proximity sensor (not shown) moulded on the machine engages the inner wall of the pipe.
  • the operator further advances the machine by operating a machine control panel (not shown), situated within the nose cone assembly and accessable to the operator, such that the automatic welder assemblies 50 project beyond the open end of the pipeline.
  • each arrester assembly 40 is then extended and rotated such that the positioning abutment 42 is axially aligned with a weld plane of the welder assemblies 50 and radially aligned with the end of the pipeline.
  • Each positioning abutment 42 is then rotated about the axis of the extendable shaft 41, and the extendable shaft is then withdrawn such that each positioning abutment lies between two adjacent rear pipe-engaging clamps 31 A, clear of the path of the automatic welder assemblies (see below).
  • control rod front coupling is reconnected to the supply of services and the air receiver tank 81 can be re-pressurized if necessary.
  • a pipe wall engaging drive system 610 comprising two track laying drive arrangements 611 positioned at the 4 o'clock and 8 o'clock positions when viewing the internal pipe welding machine from the front, and a track laying idle arrangement 612 positioned at the 12 o'clock position.
  • An actuating arrangement 614 allows the tracks of the drive arrangement and idle arrangement to move between a pipeline engaged position, shown at El of figure 4 and a pipeline disengaged position shown chain dotted at E2 of figure 4.
  • the actuating arrangement includes a double acting pneumatic actuator 620, having a body mounted on the rear subframe 13 and a ram 621 slidable relative to the body.
  • the ram moves within tube 622 also mounted on the rear subframe 13 at a right-hand end when viewing figure 4; tube 622 includes two diametrically posed slots 623 and 624 (see figure 6).
  • Slidable on tube 622 is a collar 625.
  • a pin 626 is positioned within slots 623 and 624 and is secured in holes in ram 621 and also in holes in collar 625.
  • Actuation of the pneumatic actuator 620 between an extended and a retracted position causes the collar (also known as a actuator member) to move between a disengaged and engage position respectively ie. a position where the drive and idle arrangements are disengaged and engaged respectively with the pipeline.
  • a disengaged and engage position respectively ie. a position where the drive and idle arrangements are disengaged and engaged respectively with the pipeline.
  • the actuating arrangement includes three linkage arrangements 615, one being associated with the track laying idle arrangement and the other two being associated, one with each track laying drive arrangement.
  • the linkage arrangements 615 are substantially similar thus only one will be described in detail as follows :-
  • Each linkage arrangement 615 comprises two opposite handed sets of linkage components 616 and 617 mounted one on either side of track 618.
  • the set of linkage components 616 includes a first pivot lug 630A secured to rear subframe 13.
  • First link 632A is pivotally mounted via a first pivot 631 A to first pivot lug 630A.
  • First link 632A is also pivotally mounted to axle 633 via a second pivot 634A.
  • a second link 635A is pivotally mounted at a third pivot 636A to axle 633 and also at a fourth pivot 637A to a fourth pivot lug 638A secured to collar 625;
  • components 630B, 63 IB, 632B, 634B, 635B, 636B, 637B, and 638B of the second set of linkage components 617 are equivalent to their correspondingly numbered components in the set of linkage components 616.
  • First pivot 631 therefore comprises the combination of first pivot 631 A and 63 IB.
  • First link 632, second link 635, second pivot 634, third pivot 636 and fourth pivot 637 similarly comprise the combination of their two component parts.
  • the second pivot 634 and the third pivot 636 have coincident axes but this need not necessarily be the case in further embodiments.
  • the track laying drive arrangement or track laying idle arrangement is mounted on mounting axle 633 (see below).
  • Extending the ram causes the collar to move axially towards the right when viewing figure 4 such that the fourth pivot 637 moves away from the first pivot 631 and the second 634 and third 636 pivots move radially in board along with the axle 633.
  • This causes the track laying drive arrangement or track laying idle arrangement as appropriate to disengage the pipeline wall.
  • Retraction of the ram 621 causes the fourth pivot 637 to move towards the first pivot 631 thus re-engaging the drive arrangement or idle arrangement as appropriate with the pipeline wall.
  • the idle arrangement 612 includes a side plate 641 secured to a bearing housing 642, the bearing housing houses a self aligning rotating element bearing 643 having an outer bearing race with a spherical surface thus allowing the bearing housing 641 to yaw and roll relative to the bearing 643.
  • An inner race of the bearing is secured rotationally fast to axle 633.
  • each track laying drive arrangement allows each track laying drive arrangement to pitch, roll, and yaw relative to their respective mounting axles.
  • a second side plate 640 is secured in spaced apart relationship to side plate 641 by spacers (not shown).
  • Rear idle sprocket axle 644 (see figure 8) is mounted in self-aligning bearings 645 and 646 secured to side plates 641 and 640 respectively.
  • Sprocket 645 is secured rotationally fast to sprocket mount 646 which in turn is secured rotationally fast to rear sprocket axle 644.
  • a similar arrangement (not shown) secures a front idle sprocket to side plates 641 and 640 but additionally allows movement of the front idle sprocket axle toward and away from the rear idle sprocket axle to tension the track 618.
  • Each tracking laying drive arrangement (see figure 9) includes side plates 650 and 651, mounting axle 652, front axle 653, front sprocket 654, track 655, rear axle 656 and rear sprocket 657 equivalent to those components on the track laying idle arrangement.
  • the track laying drive arrangement 611 further includes a front sprocket air actuated motor 658 connected to the front axle via front gear box 659, rear air actuated motor 660 connected to the rear axle 656 via rear gear box 661, and brake rear disc 662 also connected to rear axle 656.
  • Brake calliper 663 is mounted via mounting arrangement 664 onto side plate 651.
  • the two track laying drive arrangements and the track laying idle arrangement can be forced into engagement with the pipeline wall to provide for increased friction between the tracks of the drive arrangements to enable the internal pipe welding machine to move along the pipeline under adverse conditions eg. up gradients, or when the pipeline wall is damp.
  • the idle arrangement does not provide any drive but does allow the track laying drive arrangement to be loaded against the pipeline wall.
  • the reduction ratio in gear box 661 is different to that in gear box 659 thus when motor 660 is driving.
  • rear axle 656 (and motor 658 is idling) the internal pipe welding machine progresses at a first speed which is different from when motor 658 is driving front axle 653 (and motor 660 is idling).
  • motor 658 is driving front axle 653 (and motor 660 is idling).
  • the disc 662 and calliper 663 can be mounted on any of the front or rear sprocket axles of any of the track laying drive arrangements or the track laying idle arrangements.
  • Calliper 663 includes disengaging pistons which are biased towards the disc 622 by a braking spring.
  • the callipers operate such that supply of compressed air forces the pistons away from the brake disc 662 to release the brake. This arrangement is therefore a fail-safe arrangement wherein loss of air pressure causes the brake to be applied.
