Abstract
A pipe pulling device for pipe laying vessels comprises a moving base, a fixed base, hydraulic pressure clamping systems, a hydraulic push-and-pull system and a support. The pipe pulling device is provided with two sets of hydraulic clamping systems, arc-shaped jaws of the hydraulic clamping systems are used for clamping an outer pipe of a double-layer pipe, two outer pipes which are set to be welded in a butted mode of the two double-layer pipes are pulled together to be butted through the hydraulic push-and-pull system. Each hydraulic system includes a pair of arc-shaped jaws and a pair of extensive arms. The pair of arc-shaped jaws and the pair of extensive arms are inserted inside the square tubes of the base and capable of moving horizontally so as to complete clamping and retracting movements of the jaws. The pipe pulling device is provided with two pairs of jaws (four jaws, clamped pairwisely) to clamp the pipes. The jaws are capable of working independently when separated from tighteners, and are capable of avoiding disturbance of the tighteners to the pipe pulling device. The moving base has the advantages of being small in friction, easy to produce and economical by utilizing idler wheels to move instead of using tracks.
Description
Technical field
The utility model relates to the innovation of a kind of ocean engineering field pipe laying barge pipelaying work device.
Background technique
China's oil and gas production cumulative year after year, and the main cause that significantly increases of oil and gas production is the increase of Chinese offshore oil and gas output.Offshore production oil gas mainly relies on submarine pipeline to carry, so the effect that submarine pipeline is laid in the oil gas conveying is more and more important, and pipe extractor is as the visual plant of pipe laying barge pipelaying work, and its critical function is that pipeline pulls butt joint.
Summary of the invention:
The technical problem that the utility model solves provides a kind of pipe extractor, and when spreading bimetallic tube at sea, in order to help the welding of outer layer pipe, execution pulls butt joint to outer layer pipe.
The utility model technology contents is that a kind of pipe laying barge pipe extractor comprises motion base, fixed base, hydraulic clamping system, hydraulic pressure push-pull system and support.Pipe extractor has two cover hydraulic clamping systems, and the arc vice jaw of hydraulic clamping system is clamped the bimetallic tube outer tube, by the further bimetallic tube outer tube of two pre-butt welding of hydraulic pressure push-pull system, realizes the butt joint of bimetallic tube outer tube.Each hydraulic pressure adds clamping system and comprises a pair of arc vice jaw and a pair of extension arm, is inserted in the square tube of base, but move left and right, thus realize the action that jaw clamps and regains.
The beneficial effects of the utility model are that this pipe extractor has two pairs of jaws (promptly 4 jaws are in twos to folder) clamp, also can work alone when breaking away from stretcher, and under the environment condition of severe, can avoid the interference of stretcher folding and unfolding pipe to pipe extractor.Movable base adopts the move mode of roller rather than the mode of track, has frictional force little, easy processing, economic dispatch advantage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is pipe laying barge pipe extractor plan view
Fig. 2 is pipe laying barge pipe extractor plan view
Fig. 3 is pipe laying barge pipe extractor side view
1-hydraulic clamping system wherein; The 2-motion base; The 3-fixed base; The 4-support; The 5-supporting leg; The 6-jaw; 7-hydraulic pressure push-pull system (pair of hydraulic cylinders).
Embodiment:
1, fixed base 3 is fixed by bolts on the support 4, roller is housed on the motion base 2 can roll on the track of support 4, motion base 2 is connected by hydraulic pressure push-pull system 7 with fixed base 3, and two cover hydraulic clamping systems 1 are contained in respectively on fixed base 3 and the motion base 2.
2, hydraulic clamping system 1 clamps bimetallic tube: four oil cylinders in the hydraulic clamping system 1 stretch out simultaneously, promote the outer tube that 4 arc vice jaws 6 are clamped the bimetallic tube of two pre-butt joints, and the hydraulic clamp oil cylinder stroke is 100mm.
3, hydraulic pressure push-pull system tube drawing: hydraulic pressure adds clamping system 1 step up bimetallic tube after, sudden-pressure relay provides signal, hydraulic pressure push-pull system 7 oil cylinders begin to regain, two hydraulic clamping system 1 relative distances further, drive the bimetallic tube outer tube of two pre-butt joints, its edge butt joint is coincide, and the oil cylinder stroke of hydraulic pressure push-pull system 7 is 200mm.
4, hydraulic clamping system 1 unclamps bimetallic tube: hydraulic clamping system 1 oil cylinder is regained, and drives jaw 6 and opens, and by stretcher and three-dimensional medium-height trestle is moved bimetallic tube, the position between two pairs of jaws 6 of next joint arrival.
5, pipe extractor integral body is packaged type, can be along the moving axially of pipe, and four lifting supporting legs 5 stretch out when industrial and mineral is abominable, guarantee that pipe extractor can stable " station " work above deck.
