Description
Technical field
The utility model is a kind of drag chain, particularly a kind of oil drilling platform drag chain.
Background technique
Drag chain of the prior art is to the relevant electric wire in the drag chain, electric wire cable and pipe protection dynamics less; in the process of using, be damaged easily; simultaneously the support performance of drag chain is relatively relatively poor, cause the outside extension ability of drag chain a little less than, have the use narrow limitation.
Chinese patent 200880112506.4, a kind of cable drag chain is disclosed, a plurality of frameworks are connected to each other and form rotationally, in the guide portion that is surrounded by each framework, dispose the rectangular things such as cable, it is characterized in that possessing: the rotational angle limting mechanism of the rotational angle of restriction framework; And the arrestment mechanism that before the boundary of rotational angle, the rotation of framework is applied braking, described rotational angle limting mechanism is made of the brake piece that forms in each framework and break receiver member, by the framework that links each other in the butt of break receiver member of the brake piece of a framework and another framework limit rotational angle between the framework, the elastic protrusion that described arrestment mechanism is formed by distolateral and the framework in each framework and consist of in another distolateral receiving portion that forms with framework of each framework, when making the framework rotation of binding, the elastic protrusion of a framework contacts with the receiving portion of another framework, thereby comes relatively rotating of two frameworks applied braking by the elasticity of elastic protrusion.This structure relative complex, and the ductility of drag chain is not good, the supportive poor-performing of drag chain itself.
The model utility content
The utility model mainly is to solve the deficiencies in the prior art, compact structure, and can farthest protect electric wire, the cable in the drag chain and the pipe safety of being correlated with, the outside support performance of drag chain is strong, easy to operate oil drilling platform drag chain.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of oil drilling platform drag chain, comprise the drag chain supporting frame, be wound with the drag chain of continuous distributed on the described drag chain supporting frame, described drag chain is fixedly connected by drag chain fixed end and drag chain supporting frame, be provided with the drag chain mobile terminal in the described drag chain, the below of described drag chain supporting frame is provided with the drag chain guiding groove, and described drag chain is located in the drag chain guiding groove.
As preferably, described drag chain comprises the carrier bar of two symmetrical distributions, be respectively equipped with dunnage between the top and bottom of described carrier bar, be provided with vertical partition rod and horizontal partition rod between described dunnage, described vertical partition rod is square crossing with horizontal partition rod and distributes, form passage between described vertical partition rod and horizontal partition rod, the bottom of described carrier bar is provided with rolling bearing.
As preferably, one end and the drag chain fixed end of described carrier bar are fixedly connected, the other end of described carrier bar and another carrier bar are fixedly connected, between described carrier bar and drag chain fixed end, fix by carrier bar locating stud and pad respectively between carrier bar and another carrier bar, between described carrier bar and drag chain fixed end, be respectively equipped with wear-resistant gasket between carrier bar and another carrier bar.
As preferably, the upper and lower of described carrier bar is respectively equipped with the bending flange, is provided with fixed hole in the described drag chain fixed end, and described dunnage is C type dunnage, described vertical partition rod and laterally partition rod outward respectively cover pvc pipe is arranged.
As preferably, described carrier bar comprises front carrier bar and rear carrier bar, and described front carrier bar is fixedly connected with rear carrier bar is symmetrical, and the edge of described carrier bar is provided with wear-resistant gasket.
As preferably, described supporting frame comprises left support frame and right support frame, and an end of described left support frame and right support frame one end are superimposed, and described supporting frame is with the movement locus phase shift of drag chain.
The function of drag chain is exactly the electric wire in the motion on the protection relevant device, and cable and corresponding water pipe, hydraulic tube also have corresponding pipe, line, the cables such as tracheae.The difference of equipment, the pipe that the above disposes, line, cable thickness, size differences are also very large, and different Environmental Conditions and operating mode have all proposed very high requirement to type selecting and the intensity of drag chain.The oil drilling platform drag chain is exactly for oil drilling platform, special Environmental Conditions and operating mode, oil drilling platform all is operation at sea, work under bad environment, and special working principle cause the pipe, line, the cable that carry in the drag chain, following characteristics are arranged, quantity is many, and weight is large, and stroke is long, working environment is moist, and pH value is higher.
This just requires drag chain to accomplish:
1, the space enough can hold greatly lower all pipe, line, cables;
2, intensity can be born all water pipes and hydraulic tube water-filling at enough height, after the pressurising and the total weight of every other cable;
3, the length long enough satisfies the whole running stroke of all pipes, line, cable;
4, material is enough good, can be applicable to the abominable physical environment of ocean operation.
Two Edge Bends in the outside in every pitch chain plate form stress surface, increase greatly the stability of drag chain, and support strength; The bearing pin of carrier bar has changed the mode that in the past relies on jump ring fixing, and adopts the mode of primary and secondary screw-threaded coupling; Strut adopts C shaped steel, and unconventional high tensile aluminium alloy has namely increased holding space, has also increased drag chain intensity; For the excessive drag chain of stroke, supporting frame of processing in the whole stroke of drag chain, two cover drag chains join end to end, supporting frame is wrapped in the interior ring of two drag chains, supporting frame and drag chain move ahead synchronously or retreat, but two drag chain is to move at supporting frame all the time, support several times lifting the drag chain bearing capacity.
Therefore, the oil drilling platform drag chain that the utility model provides, compact structure, ductility is strong, and support performance is high, improves safety in utilization.
