Above-mentioned purpose is realized by following technical proposals
The marine welding of submarine pipeline is auxiliary to be made up of positioning splint, fastening bolt ear, clamping bolt, adjusting leading screw, adjusting turning handle and axial baffle mouthpart.Positioning splint is left and right respectively one group, and every group of positioning splint all is made up of upper and lower two block-shaped identical semi-circular steel plates.Weld a fastening bolt ear on the cylindrical at the every flat Kou Chu of semi-circular positioning splint two ends.On the fastening bolt ear bolt hole is arranged, clamping bolt is installed in this bolt hole.Respectively there is an axial screw thread hole at the middle part of upper and lower positioning splint, and the two ends of upper and lower two adjusting leading screws are installed in respectively in four axial screw thread holes of left and right positioning splint.The middle part of the two adjusting leading screws adjusting turning handle vertical of respectively burn-oning with leading screw.Two axial baffles spot weld respectively on the counterpart pipeline section cannula tip cylindrical.
Above-mentioned auxiliary axial screw thread hole to left and right both sides positioning splint in the mouthpart, Yi Bian be plus thread, another side is a left-hand thread.
Above-mentioned auxiliary left and right two ends screw rod one end to upper and lower two adjusting leading screws in the mouthpart is a plus thread, and the other end is a left-hand thread.
Turn to when pulling upper and lower two adjusting turning handles simultaneously when same, upper and lower two adjusting leading screws promptly draw left and right positioning splint to draw close (or leaving mutually) mutually simultaneously.
Should auxiliary can cooperate the integration of operation of boat-carrying suspender to mouthpart.Its left and right both sides positioning splint spacing is rapid adjustment at any time, and the adjacent two pipe ends maintenance that pressure is sling with one heart, to adapt to the counterpart requirement.The influence of extraneous factor such as can overcome wind, wave, flow, gush can increase stability, makes good weld seam is difficult for change, can shorten the counterpart time again, improves work efficiency, can also further improve welding quality.It is than existing simple in structure to mouthpart, and cost is low.
Accompanying drawing 1 is that the utility model is being used the state schematic side view.
Accompanying drawing 2 is that the A of accompanying drawing 1 is to schematic representation.
In conjunction with the accompanying drawings enforcement of the present utility model is described below:
In the accompanying drawing, the 1st, positioning splint, the 2nd, the fastening bolt ear, the 3rd, clamping bolt, the 4th, regulate leading screw, the 5th, regulate turning handle, the 6th, axial baffle.B is interior pipe, and C is an outer sleeve, and D is special-purpose weld bond internal lining pipe, and E is the counterpart circumferential weld.
By accompanying drawing as seen, this auxiliary to mouthpart by left and right two groups of positioning plates 1, four groups of eight fastening bolt ears 2, four tightly with bolt 3, two adjusting leading screws 4, two adjusting turning handles 5 and left and right two axial baffles 6 are formed up and down.Fastening bolt ear 2 of weldering on the cylindrical at the every flat Kou Chu of semi-circular positioning splint two ends.Clamping bolt 3 is installed in the tapped hole on the fastening bolt ear 2.Respectively there is an axial screw thread hole at the middle part of positioning splint 1 up and down, and the two ends of two adjusting leading screws 4 are installed in respectively in four axial screw thread holes of left and right positioning splint 1 up and down.The middle part of the two adjusting leading screws 4 adjusting turning handle 5 vertical of respectively burn-oning with leading screw.Two axial baffles 6 spot weld the end of counterpart pipeline section outer sleeve B respectively.
