Description
Technical field
The present invention relates to a kind of novel ship moon pool bottom hatchcover lifting device and method for improving.
Background technique
Marine field breeds huge resource, vital tissue portion of the ocean engineering support vessel as marine engineering equipment
Point, lasting operation, environmental protection, cooperation, supply etc. are provided entirely in the whole life cycle of ocean engineering for ocean engineering platform
Orientation service guarantee.
Currently, ocean engineering ancillary works ship is often equipped with underwater robot (ROV) or saturation diving clock, carried out with meeting
The prerequisite of underwater operation or deepwater work needs first in ROV or diving bell before transferring under water by hull moon bottom of pond
Portion's hatchcover is opened, and according to previous design experiences, hull moon pool bottom hatchcover is usually designed to electric hydaulic and opens form,
Design it is complex so that the design of moon pool bottom peripheral structure is also troublesome, so that entire construction cost is very expensive, due to
The hatchcover is located at Water Plane hereinafter, its opening and closing operations needs hydraulic system as power, so hatchcover and some main hydraulic
Component can be placed in moon pool, such as hydraulic cylinder and pipe fitting, and after hatchcover is opened, hatchcover and its these components can all soak
Bubble is in seawater, according to frequent duty cycle, by for a long time by the corrosion of seawater, so that reduces hatchcover system uses the longevity
Life, and then increase oil leak risk in hydraulic system.
In recent years, with the continuous reinforcement that sea environment-friendly is realized, ocean caused by various countries' associated mechanisms reveal oil product is dirty
It contaminates hidden danger and is also gradually reinforcing prevention, it is typical as Environmental Protection Agency has promulgated related request if 2013, it means greatly in beauty
State's sea area drauht is forbidden to use conventional hydraulic oil and lubricating oil with lower portion, to prevent leakage from polluting to ocean, makees
It is using degradable biological oil for alternative solution, the self-characteristic based on bio oil, to be used for conventional hydraulic system is pair
The huge challenge of hydraulic device manufacturer, and the technology is not yet universal at present, is mostly being studied as scientific research project.
Summary of the invention
The object of the present invention is to provide one kind can realize the moon well on the basis of ensuring that oil leak is free from risk
The novel ship moon pool bottom hatchcover lifting device of the opening and closing operation of bottom of pond portion hatchcover.
Present invention technical solution used for the above purpose is: a kind of novel ship moon pool bottom hatchcover promotion dress
It sets, including hoisting gear, main bearing beam, stable auxiliary body, jointing and promotion rigging, the hoisting gear, which is mounted on, to be held
The rear and front end of weight girder, two sides and main bearing beam integral structure of the stable auxiliary body in main bearing beam, the connection
Connector is mounted in main bearing beam, and the promotion rigging is arranged on hoisting gear.
It is a further object of the present invention to provide a kind of hatchcover method for improving of novel ship moon pool bottom hatchcover lifting device.
Present invention technical solution used for the above purpose is: one kind can be free from risk ensuring oil leak
On the basis of, the novel ship moon pool bottom hatchcover lifting system of the opening and closing operation of moon pool bottom hatchcover is realized well
Hatchcover method for improving, comprising the following steps:
A, lifting device is transferred to above hatchcover, and the promotion rigging on lifting device is connected with the suspension centre of hatchcover, raises and mentions
Device is risen, its wirerope is made to be in tension；
B, remove hatchcover and hull connection bolt, toward moon pool in drain, until moon pool in outboard drinking water unanimously.Decline is promoted
Device is to certain altitude, and operating the hoisting gear above lifting device turns over hatchcover, until substantially vertical；
C, lifting device is operated, rotates lifting device parallel with moon pool diagonal line to hatchcover；
D, lifting device is raised, until hatchcover bottom is higher by main deck, lid is then transferred to other regions, completes hatchcover
Unlatching promoted operation.
A kind of novel ship moon pool bottom hatchcover lifting device of the present invention and method for improving, design is simple, using reliable；It can
Effectively to prevent oil leak, in order to avoid cause the pollution to marine environment；Compared to electric hydaulic type hatchcover is used, the moon is reduced
The structure in pond designs and builds difficulty；Compared to electric hydaulic type hatchcover is used, the design for simplifying moon pool bottom hatchcover can be substantially
Reduce shipbuilding cost；It is related extra large to be applicable to all size type using very extensive and flexible for the lifting system and method
Foreign engineering ship；Based on the power that lifting device operates with, it is desirably integrated under underwater robot or saturation diving clock class
It puts in the hydraulic system of equipment, or with a small portable hydraulic pressure unit, is temporarily placed on freeboard deck, is conducive in this way
Ship deck equipment arrangement, improves the utilization rate on deck.

Specific embodiment
Novel ship moon pool bottom hatchcover lifting device and method for improving, as shown in Figures 2 and 3, moon pool bottom hatchcover
2, according to the specific structure of moon pool bottom, simplify design moon pool bottom hatchcover, makes it only and have the structural strength of requirement and reliable
Watertightness, the connection of hatchcover and Ship Structure can finally pacify according to the lifting device design that choose for common bolt connection
4 hoisting eye plates are filled as suspension centre, to connect lifting device, as shown in Figure 1, novel ship moon pool bottom hatchcover promotes dress
It sets, including hoisting gear 3a, main bearing beam 3b, stable auxiliary body 3c, jointing 3d and promotion rigging 3e, hoisting gear 3a
It is mounted on the rear and front end of main bearing beam 3b, stablizes auxiliary body 3c and is integrally tied in the two sides of main bearing beam 3b and main bearing beam 3b
Structure, jointing 3d are mounted on main bearing beam 3b, are promoted rigging 3e and are arranged on hoisting gear 3a, needed for operation winch
Power source, only can need to reserve two interfaces (one-in-and-one-out) and a reversal valve, use are hydraulic by the power source of lowering system
Hose is connect with fast interface with lifting device；Or a small portable power unit can be matched, it is placed on freeboard deck, hand
It is dynamic or electronic；As shown in Figures 1 to 7, the method for improving of novel ship moon pool bottom hatchcover lifting device, specific steps
Are as follows: lifting device is temporarily attached to underwater robot or saturation diving clock lowering system by A, when opening moon pool bottom hatchcover
4, lifting device 3 transfers to 2 top of moon pool bottom hatchcover, will promote rigging 3e and moon pool bottom hatchcover 2 on lifting device 3
Suspension centre is connected, and raises lifting device 3, its wirerope is made to be in tension；B, moon pool bottom hatchcover 2 and hull are then removed
Connection bolt, start toward the inner draining of hull moon pool structure 1, until consistent with outboard drinking water in moon pool, at this point, decline promotes dress
Certain altitude is set, the hoisting gear 3a above lifting device is operated, turns over hatchcover, until substantially vertical；D, operation is promoted
Device keeps its rotation parallel with moon pool diagonal line to hatchcover, then starts to raise lifting device, until hatchcover bottom is higher by main first
On plate, lid is then transferred to other regions using other measures, the unlatching for being finally completed hatchcover promotes operation, and the present invention faces
When depend on a moon pool equipment discharging mechanism, opening and closing operation is carried out to bottom hatchcover, simple process securely and reliably can
It is operational and adaptable, the risk that oil leak pollutes ocean can be reduced, thus reduce shipbuilding and operation at
This.
