Technical field
The utility model relates to S type stinger, relates in particular to a kind ofly when laying ocean depth waterpipe, and the A cabinet frame Abseiling device of lifting S type stinger, belongs to ocean engineering technology equipment field.
Background technology
S type stinger is the important device of laying S type submerged pipeline, in laying S type submerged pipeline process, for submerged pipeline provides support, the effect of the enough deep cambeies of smooth transition; It is the direct factor that guarantees that submerged pipeline is laid safely.And A cabinet frame Abseiling device is the device for connecting S type stinger and lifting motor.
When S type stinger is worked, by A cabinet frame Abseiling device, S type stinger is put down, complete undersea pipe-laying operation; When S type stinger is not worked, be again by A cabinet frame Abseiling device, S type stinger to be raised up, to facilitate holder boat and similar operations.
Existing A cabinet frame Abseiling device, belongs to the part of S type stinger suspension system, and it is used for adjusting S type stinger angle, to adapt to different pipe characteristics and the depth of water.Whole S type stinger suspension system comprises two large divisions: the one, and winch, can adopt electric winch or hydraulic wireline winch, and winch is with automatic self-locking function; The 2nd, A cabinet frame and multiple assembly pulley.Wherein, A cabinet frame is by horizontal frame and oblique system framework, and its side is connected with rod member, and forms side truss structure form.A cabinet frame must have enough strength and stiffness, should carry out strength and stiffness calculating according to peak load under mode of operation.In addition, multiple movable pulleys are arranged on A cabinet frame top, and associate member inhibiting device is arranged on A cabinet frame conventionally, are used for preventing that the S type stinger that wave may cause from upwards rotating, and can adopt hydraulic efficiency gear form.The installation form of rope is: the winch on the horizontal frame of left side directly connects left side steel wire cable, and then, by movable pulley and support, being connected to the left side of S type stinger first segment truss structure suspension centre, right side horizontal frame is also in like manner.
But, because S type stinger is when being subject to the power of horizontal direction, S type stinger can only provide moment by main hinge-point position, to reach balance, make S type stinger laterally easily produce wild effect, under the long-term impact of this kind of phenomenon, easily cause S type stinger to sustain damage, thereby affect the service life of S type stinger.
Utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of A cabinet frame Abseiling device of the S of lifting type stinger, it can use in the pipelaying process of different water depth, not only can effectively alleviate stormy waves stream in marine environment and, on the laterally impact of effect of S type stinger, increase stinger lateral stiffness; And when stinger one side is when stressed, an other side rope provides restoring force, avoids S type stinger Concentrated load power to produce; Meanwhile, reduce the load power horizontal to S type stinger, improved the service life of rope and the safety and reliability of use.
The purpose of this utility model is realized by following technical scheme:
A kind of A cabinet frame Abseiling device that lifts by crane S type stinger, be provided with a rope being connected between A cabinet frame and S type stinger, it is characterized in that: this rope is arranged in a crossed manner, rope infall arranges an anti-rope wear device, this anti-rope wear device comprises: the plate of chute in the middle of two arranged in a crossed manner and bands of linking into an integrated entity, rope is through the chute of plate and be arranged in the chute of plate.
Described rope adopts steel wire cable.
Described rope and plate be installed as free-running fit, and keep sufficient lubrication.
Being connected between described two plates can be at any time because the stressed activity of adjusting angle coordinates.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, it can use in the pipelaying process of different water depth, not only can effectively alleviate stormy waves stream in marine environment and, on the laterally impact of effect of S type stinger, increase stinger lateral stiffness; And when stinger one side is when stressed, an other side rope provides restoring force, avoids S type stinger Concentrated load power to produce; Meanwhile, reduce the load power horizontal to S type stinger, improved the service life of rope and the safety and reliability of use.

The specific embodiment
As shown in Fig. 1-Fig. 2, the utility model is provided with: the A cabinet frame on a S type stinger 5, installation S type stinger 5, be connected to the rope 3 between A cabinet frame and S type stinger 5, wherein, A cabinet frame by horizontal frame 1, be arranged on that the oblique framework 2 of horizontal frame 1 one end forms; Rope 3 is arranged in a crossed manner, rope infall arranges an anti-rope wear device 4, this anti-rope wear device 4 comprises: two arranged in a crossed manner and by bolt and nut the plate 4.2 to chutes in the middle of 4.3 bands that link into an integrated entity, rope 3 is arranged in the chute of plate 4.2 through the chute of the plate 4.2 of chute in the middle of band, with the wearing and tearing that prevent that rope 3 is mutual.
During use, one end of horizontal frame 1 is connected with one end of rope 3, meanwhile, one end of rope 3 is connected with hoister winch, the other end of rope 3 be connected to S type stinger 5 first segment truss structure suspension centre hook place; And the horizontal frame 1 of opposite end is also in like manner with being connected of rope 3; Thereby, form an anti-rope wear device 4 arranged in a crossed manner.Then, when hoister winch (power type or hydraulic) normally starts, the driven by rotary disc rope 3 on it carries out folding and unfolding winding, because rope 3 is the plate 4.2 at the middle chute of band arranged in a crossed manner in folding and unfolding process, has prevented mutual wearing and tearing.
Above-mentioned rope 3 materials adopt steel wire cable, need meet mechanical property requirements and state-set standard; Bolt arrangement and plate all adopt national standard, need to lose efficacy and check to prevent that intensity and toughness lost efficacy; The free-running fit that is installed as of rope 3 and plate 4.2, and keep sufficient lubrication.
Above-mentionedly for connecting two plate 4.2 bolt and nuts, to 4.3, for movable, coordinate, can be at any time because of the stressed angle of adjusting, to guarantee that S type S type stinger hoists, unload the variation of the rope angle while moving.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
