Description
Technical field
The present invention relates to the shipbuilding technical field, be meant that specifically a kind of anchor chain cooperates the new technology of installing with cable stopper.
Background technology
Boats and ships are in underway; Swing or rock in order to prevent that anchor from producing in the curling position; Need anchor chain be tightened up and fixes with the plug-in strip on the cable stopper, cooperate installation situation as shown in Figure 1 when the anchor chain of convention is made in dock with cable stopper, comprise anchor chain 10, cable stopper 20 and deck 30; Anchor chain 10 is through the formation that is interlocked each other of some chain links 101; Fastening formation between each chain link 101 is 90 and spends cross chain and the perpendicular chain structure that the cycle changes, and promptly is perpendicular chain for any n chain link 101, and then the chain link 101 at n-1 and n+1 place must be cross chain; One end joining shackle 102 of anchor chain 10, the duty of shackle 102 is necessary for the cross chain state.If deck 30 and hawse-pipe 301 fully by the designing requirement manufacturing during assembling; As shown in Figure 1; Then certain chain link 101 of anchor chain 10 should be lived by plug-in strip 201 and cylinder 202 locks; Promptly this chain link 101 is spacing by plug-in strip 201 and cylinder 202 near the termination of hawse-pipe 301 1 sides, and shackle 102 is the cross chain state.But owing to have foozle when making deck 3 and hawse-pipe 301, when therefore installing, plug-in strip 201 usually lock in the somewhere, middle part of chain link 101, as shown in Figure 2.In order to make the end of plug-in strip 201 ability locks at chain link 101; Cable stopper 20 need be installed on the deck 30 when mounted in advance; Again according to the rigging position of plug-in strip 201 with anchor chain 101 ends; With graphing method cable stopper 20 is carried out the front and back translation or reduces height, promptly cable stopper 20 is adjusted to repair and cut, be fixed at last on the deck 30.
It is as shown in Figure 3 that the repairing of cable stopper cut operation principle, i.e. graphing method is when the plug-in strip lock is lived the somewhere, middle part of chain link; Suppose that the chain ring length is that A, diameter are D, plug-in strip be a (wherein 0 < a < A) apart from the trailing edge of institute's brake chain ring distance, and the vertical range on measurement gained cable stopper axle center to deck is H; The horizontal range at cable stopper axle center to hawse-pipe center is L, for make plug-in strip effectively lock live the front end of anchor chain, must carry out moving of horizontal direction to cable stopper so; And the cutting of vertical direction; The distance that wherein moves forward is l=(A-a) cos θ, and repairing the distance of cutting downwards is h=(A-a) sin θ, and fact proved; Operating personnel are usually for want of absolute effective technical means in repairing the process of cutting, and only cuts by rule of thumb and causes scrapping of cable stopper; After perhaps lock was lived anchor chain on request with plug-in strip, shackle can't satisfy user demand, and the adjustment space of cable stopper was very limited, can't regulate once more, has caused scrapping of cable stopper equally for perpendicular chain state; Perhaps level off to zero the time when the length of a, downward cutting distance and the displacement forward of cable stopper will exceed tolerance band, for ease of understanding, illustrate as follows:
If the diameter D=73mm of anchor chain draws A=438mm according to GB; Suppose a=A/4=109.5mm, the θ angle is generally 35 ~ 48 °, so draw
l=（A-a）cosθ=269~180mm
h=（A-a）sinθ=188~139mm
And generally speaking, the forward pitch that the cable stopper designing institute allows is from being 50mm, and highly cutting surplus is 100mm, so cable stopper causes and can't construct because of exceeding moving range.
In sum, prior art has restricted production efficiency, and particularly in a single day sincere chain device cuts improper scrapping because of repairing, and just possibly have a strong impact on the duration of product, has caused the waste in human and material resources and man-hour.
