Description
Technical field
The present invention relates to anchoring system windlass field, a kind of chain wheel for hawse pipe cable stopper.
Background technique
Cable stopper is that anchor is clamped in ship/semisubmersible platform/Floating Production storage handler (FPSO) when navigating by water or casting anchor
The device of chain is mainly used for clamping anchor chain after casting anchor, and pulls anchor chain and bears anchor chain pulling force, so that it is passed to anchor chain sprocket
On, so that windlass is not at stress, or tense the special implement for having taken in the anchor of hawse-pipe.
By China Classification Society (CCS) code requirement, cable stopper should be able to bear the experiment load for being equivalent to anchor chain, and its stress
The 90% of its material yield strength value should be not more than.The code requirement of the classification societies such as Lloyd's Register of Shipping (LR) and DNVGL,
Cable stopper should be able to bear the 80% of the minimum breaking load of passed through anchor chain, its primary structure member should not generate permanently in the case
Deformation.
When traditional cable stopper works, chain wheel for hawse pipe is in below hull, and anchor chain folding and unfolding is usually to pass through lower guide from water
Chain idler wheel is then sent to windlass using cable stopper on deck, mainly makes chain wheel for hawse pipe bear main stress in this way, causes to lead
Deck pedestal bears load.
Summary of the invention
According to the working condition of traditional cable stopper and chain wheel for hawse pipe set forth above, be from water by lower part chain wheel for hawse pipe again
It is then sent to windlass by cable stopper on deck, mainly makes chain wheel for hawse pipe bear main stress in this way, causes main deck pedestal
The technical issues of bearing load, and a kind of chain wheel for hawse pipe cable stopper is provided.The present invention, which mainly has using load unit top, to draw
The guide groove of guide chain item, there are two the button that snubs the chain for locking chain, guide groove front end is provided with for logical for chain the interior setting of guide groove
The guide chain hole crossed, long swing arm top are provided with the chain wheel for hawse pipe of guidance chain；Rotary shaft is fixed on hull by rack, from
And play and merge chain wheel for hawse pipe and cable stopper, by having exchanged the position of chain wheel for hawse pipe and the mechanism that snubs the chain, and will lead
Chain idler wheel and the mechanism that snubs the chain have been installed along with hull side, and installation site allows to be located under waterline, and constraint maximum load is having
The region of limit effectively reduces main deck bed load, greatly reduces anchor chain abrasion, static and fatigue stress.
The technological means that the present invention uses is as follows:
A kind of chain wheel for hawse pipe cable stopper, including rotary shaft and long swing arm, the long swing arm front end have load single
Member, the load unit top have the guide groove of guidance chain, and there are two the tugs for locking chain for setting in the guide groove
Cuff link, the guide groove front end are provided with the guide chain hole for passing through for chain, are provided with guidance chain above the long swing arm
Chain wheel for hawse pipe；The rotary shaft is fixed in hull sides by rack, and the rotary shaft is enable to turn with respect to rack
It is dynamic, rotating arm is provided in the rotary shaft.
The chain wheel for hawse pipe is installed on idler wheel swing arm front end, the long swing arm end and idler wheel swing arm end
By being installed on the rotating arm hingedly by rotating shaft, the long swing arm and the idler wheel swing arm is enable to distinguish phase
The rotating shaft is rotated, realization is swung up and down.
When snubbing the chain, button unclamps, and chain leads into the load unit of long swing arm by chain wheel for hawse pipe, and passes through guide chain hole
Transmission is stretched out；When the padlock that snubs the chain is tight, chain is fixed in the guide groove of load unit.
Further, the rotating arm and rotary shaft are an integral structure, and the rotating arm is triangle pivoted arm, this three
One of side of angular pivoted arm is rotary shaft.
Further, the long swing arm is swung as the rotating arm can be realized 180 ° of left and right.
Further, the deduction of points that snubs the chain described in two, which Tong Guo not snub the chain, detains shaft and is mounted on the load unit, rotation institute
It states to snub the chain and detains shaft and can be realized the locked of the button that snubs the chain and unclamp；When the chain on load unit is moved to certain position,
By snub the chain detain shaft drive snub the chain button rotation, be anchored in the vertical chain link having on chain, to clamp chain.
Further, the load unit is installed on position under the hull water level line by rack.
Compared with the prior art, the invention has the following advantages that
1, long swing arm front end has load unit, and the load unit top has the guide groove of guidance chain, described
There are two the button that snubs the chain for locking chain, the guide groove front end is provided with the guide chain for passing through for chain for setting in guide groove
Hole, the long swing arm top are provided with the chain wheel for hawse pipe of guidance chain, and the supporting part of cable stopper is compact to design, and constraint is most
Heavy load is in limited region.
2, cable stopper is fixed in hull sides by rack, and even load unit is installed on the hull by rack
Position under water level line, hull installation site help to reduce the weight of Texas deck.
3, unique design allows on the rotation stopper arms of the anchor chain length that is locked in hull side, and be located at waterline with
Under.
4, maximum load can be constrained in limited region, while greatly reducing anchor chain abrasion, static and fatigue stress.
Chain wheel for hawse pipe cable stopper of the present invention, under normal operation circumstances still in sea level more than, can specifically say
Hull on the outside of the bright ship below deck level within the scope of two meters.Under severe sea condition or in the case that drinking water tonnage changes,
It is allowed to be in water level line or less.
The present invention can store up handler (FPSO) anchoring system in ship/semisubmersible platform/Floating Production based on the above reasons
The fields such as windlass are widely popularized.
