Abstract
The invention provides a parasitic seawater pump frame capable of going up and down. The parasitic seawater pump frame mainly comprises a guide protection pipe, a water lifting pipe, a lifting rack, a submersible pump, a seawater hose, a lifting unit, guide supporting arms and the like. The guide protection pipe is fixed to a platform pile leg in a parasitic mode, and the water lifting pipe is installed inside the guide protection pipe and capable of sliding along the guide protection pipe, so that the dependence on the rigidity of the seawater pump frame is reduced. Meanwhile, the lifting unit is engaged with the rack installed on the water lifting pipe, so that lifting movement of the water lifting pipe and lifting movement of a seawater pump are achieved. The parasitic seawater pump frame capable of going up and down has the characteristics of being compact in structure, light in weight, capable of going up and down flexibly and convenient to operate. The dependence on the rigidity of the seawater pump frame in an ocean environment condition is reduced, and the water taking requirements for a platform under the large air gap operating condition are met.
Description
Technical field
The present invention relates to a kind of parasitic type sea water pump bracket being freely lifted in ocean engineering device field, particularly to a kind of parasitic type sea water pump bracket being freely lifted for circular column leg jack-up unit.
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: declined by sea water pump bracket, sea water pump is sent in sea water, 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 parasitic type sea water pump bracket is proposed, 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 liftable parasitic type sea water pump bracket of one involved in the present invention is achieved through the following technical solutions: including lifting pipe and immersible pump, guiding pillar, lifter rack and lifting unit, lifting unit is fixed on platform; Guiding pillar parasitism is fixed on platform leg, and lifting pipe is installed in guiding pillar; Radially mounted guide support arm between lifting pipe and guiding pillar, the outer of guide support arm is interior with the pillar that leads along tangent, and lifting pipe and guiding pillar are slidably matched by guide support arm composition; Guiding pillar sidewall sets opening vertically, sets lifter rack outside lifting pipe, and lifter rack self-steering pillar opening part stretches out guiding pillar, and engages with the gear composition gear of lifting unit.
Guide support arm top is provided with roller or slide block, and guide support arm is uniformly distributed in lifting pipe circumference, and quantity is at least three.Sea water flexible pipe is fixedly mounted on lifting pipe outlet.
The liftable parasitic type sea water pump bracket of the present invention, one of typical feature is that guiding pillar parasitism is fixed on platform leg, lifting pipe is installed in guiding pillar, at the radially mounted some guide support arms of lifting pipe differing heights, the outer of guide support arm is interior with guiding pillar along tangent, lifting pipe can slide in guiding pillar, and thus load suffered by sea water pump bracket is transmitted on high rigidity spud leg, reduces the dependence to submerged pump bracket stiffness by itself. The two of its feature are that guiding pillar one side sets opening, set lifter rack outside lifting pipe, and lifter rack stretches out guiding pillar from opening part, and the gear of lifting unit engages and drive lifting pipe and immersible pump lifting with lifter rack. The three of its feature are that sea water pump is installed in lifting pipe lower end, and top is installed and connected sea water flexible pipe, the seawater equipment on sea water flexible pipe other end connecting platform. The four of its feature are that guide support arm top is provided with roller or slide block, for reducing the lifting resistance of lifting pipe.
The beneficial effect of the 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.

Detailed description of the invention
As shown in Figure 1 and Figure 2, the liftable parasitic type sea water pump bracket of the present embodiment is achieved through the following technical solutions:
Liftable parasitic type sea water pump bracket mainly includes guiding pillar 1, lifting pipe 2, lifter rack 3, immersible pump 4, sea water flexible pipe 5, lifting unit 6 and guide support arm 7. One of its typical characteristic is that guiding pillar 1 parasitism is fixed on platform leg 9, lifting pipe 2 is installed in guiding pillar 1, at the radially mounted some guide support arms 7 of lifting pipe 2 differing heights, the outer of guide support arm 7 is interior with guiding pillar 1 along tangent, lifting pipe 2 can slide in guiding pillar 1, thus load suffered by sea water pump bracket is transmitted on high rigidity spud leg 9, reduces the dependence to sea water pump bracket stiffness by itself. The two of its feature are that guiding pillar 1 one side sets opening, set lifter rack 3 outside lifting pipe 2, and the gear of lifting unit 6 engages with lifter rack 3 and drive lifting pipe 2 and immersible pump 4 to lift. The three of its feature are lifting pipe 2 lower end installing submersible pumps 4, and top connects installs sea water flexible pipe 5, the seawater equipment on sea water flexible pipe 5 other end connecting platform. The four of its feature are that roller or slide block are installed in guide support arm 7 top, for reducing the lifting resistance of lifting pipe 2.
The use procedure under platform different conditions of the liftable parasitic type sea water pump bracket involved by this patent is described:
1, during platform standing at work state, as needed platform to take sea water, then the gear of lifting unit 6 rotates forward as drivewheel and drives lifting pipe 2 to decline along guiding pillar, and immersible pump 4 is placed in sea level less than 10, fetches water. As keeped in repair immersible pump 4 or lift up lifting pipe 2, then the gear of lifting unit 6 drives lifting pipe 2 to rise along guiding pillar 1 as drivewheel reversion, and is risen on platform 8 by immersible pump 4.
2, lifting platform or spud leg jacking condition: relative motion occurs for platform 8 and spud leg 9, spud leg 9 band action-oriented pillar 1 and lifting pipe 2 do elevating movement, now the gear of lifting unit 6 is in idle pulley state as follower, only the motion of lifting pipe 2 is play the guiding role.
