Abstract
The present invention provides a liftable attached-type sea water pump rack. The liftable attached-type sea water pump rack mainly comprises a guiding protective pipe, a lifting pipe, a sea water pump, a sea water flexible pipe, a hoisting ear plate, an elevating unit and a guiding pulley and the like. The guiding protective pipe is fixed on a platform leg, the lifting pipe is installed in the guiding protective pipe and can slide along the guiding protective pipe, and the dependence on the self rigidity of the sea water pump rack is reduced. At the same time, through the elevating unit on the top of the platform leg, a wire rope is employed for hoisting, and elevating motions of the lifting pipe and the sea water pump are achieved. The liftable attached-type sea water pump rack is characterized by being compact in structure, light in weight, flexible in elevating and convenient to operate. Under the sea environment condition, the dependence on the self rigidity of the sea water pump rack is reduced. The liftable attached-type sea water pump rack satisfies the water taking demand under the large air gap working condition of the platform.
Description
Technical field
The present invention relates to a kind of adhesion type sea water pump bracket being freely lifted, particularly to a kind of adhesion type sea water pump bracket being freely lifted for circular column leg jack-up unit, belong to ocean engineering field.
Technical background
Circular column leg formula jack-up unit is one of requisite equipment pattern in marine energy exploration and development process.Platform is in the standing at work process of marine site, main platform body distance sea certain altitude (referred to as air gap), the most important water intaking approach movable into maintaining platform fire-fighting, production, life etc. put up by its entrained sea water pump, its main operation principle is: is declined by sea water pump bracket and sends in sea water by sea water pump, and by the pipeline on sea water pump bracket, sea water is introduced on platform.Current circular column leg formula jack-up unit sea water pump bracket is mainly independent truss-like pump bracket, it is to be formed independent truss structure by steel-pipe welding, sea water pump is installed on pump bracket bottom, the motion of sea water pump bracket is controlled by jacking system, it has simple in construction, kinematic dexterity relatively high, it is possible to be adapted to platform water intaking requirement when small air gap.But the continuous increase along with platform air gap requirements, cause improving constantly therewith the demand of sea water pump bracket rigidity to resist the huge bending moment that wave loadings causes, ultimately result in sharply increasing of sea water pump bracket sectional dimension, construction weight, cost etc., bring adverse effect to platform operations safety, platform space utilization and cost control etc..Therefore, the use under the big air gap operating condition of platform of the independent truss-like pump bracket is extremely limited.
Summary of the invention
It is an object of the invention to as solving the problems referred to above, a kind of liftable adhesion type sea water pump bracket is provided, for meeting the water intaking demand under the big air gap operating condition of self-elevating ocean platform, the adverse effect that platform is produced by reduction construction weight and size, reduce wave loadings and the air gap change impact on pump bracket rigidity requirement, improve motility and the suitability of sea water pump bracket.
The technical scheme is that:
A kind of liftable adhesion type sea water pump bracket, including guiding pillar 1, lifting pipe 2, sea water pump 3, sea water flexible pipe 4, lifting otic placode 5, lifting unit 6 and leading block 7；Wherein: guiding pillar 1 attachment is fixed on platform leg, and lifting pipe 2 is set in guiding pillar 1, and sea water pump 3 is connected to the bottom of lifting pipe 2, and sea water flexible pipe 4 is connected to the top of lifting pipe 2；Lifting unit 6 is fixed on spud leg top, is connected to the lifting otic placode 5 on lifting pipe 2 by steel wire rope and leading block 7.
Such scheme also includes: install anti-collision rubber ring 8 on lifting pipe 2 differing heights；Anti-collision rubber ring 8 leaves gap with guiding pillar 1.Described lifting unit is electrical hoist.
The beneficial effect of the invention:
The liftable adhesion type sea water pump bracket of one that relates to of invention, have compact conformation, lightweight, lift flexible, easy to operate feature.Reduce the dependence to sea water pump bracket stiffness by itself under marine environmental conditions, adapt to the water intaking demand under the big air gap operating condition of platform.
Accompanying drawing explanation
Fig. 1 is a kind of liftable adhesion type sea water pump bracket schematic diagram.
Fig. 2 is a kind of liftable adhesion type sea water pump bracket horizontal cross.
In figure: 1 guiding pillar, 2 lifting pipes, 3 sea water pumps, 4 sea water flexible pipes, 5 lifting otic placodes, 6 lifting units, 7 leading blocks, 8 anti-collision rubber rings.
Detailed description of the invention
As shown in Figure 1 and Figure 2, one involved in the present invention liftable adhesion type sea water pump bracket is achieved through the following technical solutions: liftable adhesion type sea water pump bracket mainly includes guiding pillar 1, lifting pipe 2, sea water pump 3, sea water flexible pipe 4, lifting otic placode 5, lifting unit 6, leading block 7 and anti-collision rubber ring 8.One of its typical characteristic is that guiding pillar 1 attachment is fixed on platform leg, lifting pipe 2 is installed in guiding pillar 1, lifting pipe 2 differing heights is installed anti-collision rubber ring 8, anti-collision rubber ring 8 retains certain interval with guiding pillar 1, lifting pipe 2 can slide in guiding pillar 1, thus load suffered by sea water pump bracket is transmitted on high rigidity spud leg, reduces the dependence to sea water pump bracket stiffness by itself.The two of its feature are that spud leg top is provided with lifting unit 6, use the lifting otic placode 5 that steel wire rope connects on lifting pipe to make lifting pipe 2 and sea water pump 3 one lifting.The three of its feature are that sea water pump 3 is installed in lifting pipe 2 lower end, and top is installed and connected sea water flexible pipe 4, the seawater equipment on sea water flexible pipe 4 other end connecting platform.The four of its feature are that lifting pipe is provided with anti-collision rubber ring 8, for reducing the lifting pipe collision harm to guiding pillar 1 and spud leg.
This liftable adhesion type sea water pump bracket use procedure under platform different conditions is described:
1, during platform standing at work state, as needed platform to take sea water, then the lifting pipe 2 that lifting unit 6 releasing of brake steel wire rope connects declines along guiding pillar 1, and sea water pump 3 is placed in below seawater levels, fetches water.As keeped in repair sea water pump 3 or lift up lifting pipe 2, then lifting pipe 2 is risen along guiding pillar 1 by lifting unit 6 by steel wire rope, and is risen on platform by sea water pump 4.
2, lifting platform or spud leg jacking condition: platform and spud leg generation relative motion, spud leg band action-oriented pillar 1 and lifting pipe 2 do elevating movement, now lifting unit 6 place braking state, only to 2 fixations of lifting pipe.
