Description
Technical field
System is pulled the present invention relates to a kind of pipeline for carrying out load test on hull.
Background technology
On pipe laying barge, its pipelaying work system can set a set of stretcher and A/R hoister systems, for clamping, receiving
Put extra large pipe.After stretcher and the shipment of A/R winches, the requirement based on instrument factory and shipowner side can typically pay in ship and advance
The load test of row stretcher and A/R winches, to verify that equipment normal work and can reach design performance after loading onto ship.The load
The general principle of experiment is：Manage the traction of upper or A/R winches in the sea that stretcher clamping is loaded into by shipyard one external pull of offer
Steel wire rope on, if Hai Guanneng is firmly clamped without skidding off in the presence of external pull, or A/R winches can overcome this outer
Portion's pulling force does not slip rope, and stretcher or A/R winches parameters normal operation, then test successfully, equipment spreads after being used for
Pipe operation.Because the external pull typically requires larger, up to 100 tons or so, therefore for shipyard, the process of the test
Middle maximum difficult point is how reliably and securely to provide this external pull.
The method that general shipyard can refer to Fig. 1 is tested：Make stern towards harbour, ship mooring is good, on the quarter open
One frock pulley yoke is installed at mouthful, external pull is provided using truck crane.Had the following disadvantages in the method implementation process：
1) a large-scale frock pulley yoke need to be made and need to be welded in the structure being on the quarter open, made and installment work
Amount is big；
2) because load is larger, frock installation site needs to carry out calculating and the strength check of complexity；
3) ship need to adjust attitude, make stern towards harbour, it is necessary to move ship；
4) truck crane of extra lease large-tonnage is needed；
5) the method is considered, although but feasible compare consuming time and cost.
In the prior art, Chinese patent 201410491090.9 discloses a kind of tensile test system of pipe laying barge, including：
Leading block, frock cable wire, set square, pulling winch cable wire, current nipple, stretcher, pulling winch, pipeline, set square
It is connected with pulling winch by pulling winch cable wire, current nipple is connected with the pipeline through stretcher, pulling winch cable wire
Through current nipple, leading block is fixedly connected with fixed pedestal, frock cable wire bypass leading block respectively with set square and
Current nipple is connected, and current nipple includes pulling eye plate.The invention also discloses a kind of pull force test method of pipe laying barge,
The present invention replaces traditional fixed hanger to be equipped with one simultaneously using detachable deflection sheave device can be applicable not by repacking
With the general tow attachment of caliber, the space shared by tensile test system is significantly reduced, improve efficiency, while solving
Leading block is located at side and miscellaneous equipment afoul problem in ship.
The defect of above-mentioned technical proposal is larger workload, compares consuming time and cost.
Therefore, how providing one kind can be greatly decreased workload, time-consuming and cost, while can also safely and reliably carry
Pipeline dragging system for external pull becomes the problem that industry needs to solve.
