Abstract
The invention discloses an escape ladder of an FLNG ship. The escape ladder comprises an upper straight ladder body and a lower straight ladder body. A winch is arranged between the upper straight ladder body and the lower straight ladder body. The lower end of the upper straight ladder body is arranged on the lower end face of the winch, and the upper end of the lower straight ladder body is connected to the upper end face of the winch. By means of the escape ladder, influences of flood tide and ebb tide are reduced to a large extent, and the inclination degree of the escape ladder is reduced during flood tide. The movement angle range of the escape ladder can be increased due to segments at the tail end, and the ladder can meet requirements even the tide water fall range is large. Accordingly, the escape ladder is particularly suitable for being used for a long time in the environment where tidal influences are large.
Description
Technical field
The present invention relates to a kind of escape ladder, particularly relate to a kind of escape ladder being applicable to FLNG boats and ships.
Background technology
FLNG boats and ships are non-self boat liquefied natural gas barges, deck are arranged liquefying plant and the module that gasifies again.Can be furnished with very many Large Steel pile tubes around during operation in this marine site, ship place, these steel pipe piles are distributed in the whole body of ship, play fixing boats and ships.When causing danger, to flee from the scene of the accident, first arriving steel pipe pile top platform by escape ladder, then running away on the bank from steel pipe pile.
When FLNG boats and ships are in the good marine site work of some environment, existing escape ladder just can satisfy the demands.If when the marine site ambient environment situation more complicated of FLNG vessel operation, so existing escape ladder just can not meet corresponding demand.As the working environment of Colombian island formula harbour, be can carry out self-control along with the fluctuation tide of seawater to the requirement of escape ladder; Simple to operate, passage rate is fast; Safety and stability is reliable, not by weather effect.
Existing escape ladder be only suitable for stormy waves less, by the little environment of tidal effect, and mode of operation can not be remained, be subject to the impact of wave and weather, safety rate impact that is low, that be subject to flood tide and ebb tide of passing through is larger.
Obviously, when FLNG boats and ships are arranged on the working environment as Colombian island formula harbour, existing escape ladder can not meet relevant requirement.
Summary of the invention
Technical matters to be solved by this invention is the deficiency for existing FLNG ship escape ladder, there is provided a kind of escape ladder of FLNG boats and ships, when after this escape ladder can remain operating condition, flood tide, little, the personnel of its gradient impact pass through, higher, the required platform active area of safety is less, simple to operation.
In order to solve the problems of the technologies described above, the escape ladder of a kind of FLNG boats and ships of the present invention, comprise vertical ladder, also comprise lower vertical ladder, capstan winch is provided with in the middle of described upper vertical ladder and lower vertical ladder, the lower end of described upper vertical ladder is arranged on the lower surface of capstan winch, and the upper end of described lower vertical ladder is connected on the upper surface of capstan winch.
Lower vertical ladder is connected to by bolt or chain and capstan winch both can have realized up and down, capstan winch can be utilized again to carry out left and right movable.This just substantially increases the action radius of lower vertical ladder, can the change of suitable environment.
The further improvement project of technique scheme, the bottom of described lower vertical ladder is provided with turning rolls.By turning rolls, lower vertical ladder is better moved on steel pipe pile platform.
The further improvement project of technique scheme, also comprises podomere, and described podomere is connected to the lower end of lower vertical ladder.Podomere part increases a podomere on lower vertical ladder, the action radius of vertical ladder on the platform of below because tidewater fluctuation causes can be greatly reduced after adding this podomere, greatly can improve the degree of utilization of platform, for escape platform, its effect is huge.
Present invention employs the building form of capstan winch, lower vertical ladder and podomere, reduce the impact that flood tide and ebb tide bring to a great extent, decrease the degree of dip of escape ladder at the incoming tide; And due to the podomere part of tail end, can increase the activity point of view scope of escape ladder, even if tidewater fall range is comparatively large, this ladder also can satisfy the demands.Therefore this escape ladder is particularly suitable for long-term operation under the environment larger by tidal effect.
Accompanying drawing explanation
Fig. 1 is the main TV structure figure of escape ladder under different water position status;
Fig. 2 is the plan structure figure of escape ladder under hull and steel pipe pile platform different distance state;
Fig. 3 is podomere part-structure enlarged drawing.
Detailed description of the invention
1 to 3 is known by reference to the accompanying drawings, the escape ladder of a kind of FLNG boats and ships of the present invention, comprise vertical ladder 1, described upper vertical ladder 1 is fixed ladder, described upper vertical ladder 1 is that lower end is fixedly connected with capstan winch 3, capstan winch 3 is horizontally disposed with, and outside the disk of capstan winch 3, direct bolt hole connects lower vertical ladder 2, and described lower vertical ladder 2 is autostairs.Lower vertical ladder 2 can be transformed with common vertical ladder.The lower end of the bolt of lower vertical ladder 2 is connected with podomere 4, and the bottom of lower vertical ladder 2 is provided with turning rolls 5, and the top, lower end of podomere 4 is provided with roller 6, and podomere 4 carries out auxiliary connection by chain and lower vertical ladder 2.
Also be provided with loop wheel machine 7, loop wheel machine 7 is arranged on two decks.Described loop wheel machine 7 is connected on lower vertical ladder 2 by steel rope, is preferably disposed on the bottom of lower vertical ladder 2.
Adopt the mode two decks being arranged loop wheel machine 7, escape ladder and can regulate rope capacity to control lifting and the transverse shifting of vertical ladder 2 under escape ladder by the arm of jenny 7, simple to operate, safe, time saving and energy saving, for escape ladder, this point seems particularly important.At the incoming tide, control lower vertical ladder 2 by loop wheel machine 7 and decline, also can loosen the steel wire that loop wheel machine controls, utilize the gravity of ladder self to regulate.During ebb tide, lower vertical ladder 2 and podomere 4 are by the rolling of roller, and loop wheel machine 7 also can be utilized to regulate, and inclined ladder degree of dip reduces gradually, and when being reduced to minimum, lower vertical ladder 2 is basic concordant with steel pipe pile platform 8 with podomere 4.
