Abstract
A match structure for the anchor lip of high-speed ship and bow anchor is composed of an anchor with a projected plate on its crown and an anchor lip fixed to the opening of anchor chain channel and with a slippery transition surface on its lower lip. When said bow anchor is weighted, its projected plate is frictioned with said slippery transition surface to force the anchor to be turned over and make it close to hull.
Description
Technical field
The invention belongs to the ground tackle field, more particularly relate to anchor lip on the thin ship type high speed vessel of stem point and a kind of fit structure of single bower, when weighing anchor, the anchor fluke that this structure can the bonding bower can be turned over voluntarily, rocks to be adjacent to hull and to prevent.
Background technology
Require bower can successfully enter hawse pipe when ship is weighed anchor, and make anchor chain (or anchor cable) tension back anchor should be close to hawse pipe bead or anchor fluke and planking to be close to, the big stormy waves anchor of ship navigation chance should not rock.
The ship anchor mainly partly is made up of anchor shackle, anchor pole, anchor fluke and bearing pin etc., and anchor pole is connected by bearing pin with anchor fluke, can relatively rotate, and we call crown to an end of the close rotating pin of anchor fluke again.Anchor fluke and anchor pole all have a spacing angle when rotating, and press anchor pattern difference, and this angle is slightly variant, is example with the bohr anchor, and its angle is 42 °
-05 + 2, as shown in Figure 1.
Usually be subjected to the restriction of anchor gear on the deck, hawse pipe aperture position above deck is definite substantially, after the deck opening position is selected, select to be suitable for the angle β that the hawse pipe axis of this ship at the deck opening place become with plumb bob vertical again, because the size of β angle relates to the length of hawse pipe, hawse pipe and hull structure be connected and anchor tension back apart from water surface elevation or the like, need the factor considered many.
When tension anchor cable (anchor chain), after anchor entered hawse pipe, anchor fluke must be to ship rear upset, and after so just guaranteeing to strain anchor, anchor fluke and hull are close to and are not rocked.With the bohr anchor is example, because the angle that locks between anchor pole and the anchor fluke is 42 °
-05 + 2Anchor leaves the water surface after weighing anchor, the anchor cable of this moment is overhang (as Fig. 2), therefore the state of equilibrium of anchor is that anchor fluke is all possible to both direction, that is to say that anchor fluke is to ship rear or all possible to ship the place ahead, have only when β angle during greater than 44 °, anchor pole begin to enter just can guarantee behind the hawse pipe anchor fluke to the ship rear to upset, but analyze technically and high speed vessel head end line style and structure consideration all can not be selected β angle greater than 44 °.Therefore when the back anchor of weighing anchor leaves the water surface, if anchor fluke just can not continue to weigh anchor when fall in ship the place ahead, and can only rely on swivel could continue to weigh anchor during the vessel turning rear voluntarily by anchor fluke, and like this just can not guarantee once to weigh anchor successfully, thereby make weigh anchor chronic, wasted many valuable time and crewman's energy, we know when ship in stormy waves, do not cast anchor and the situation of not navigating by water under wave than ship in navigation the time wave much bigger, make crewman's susceptible to tired, increased crewman's labour intensity.
After anchor chain (or anchor cable) tension, the applying of anchor and hull should be tight, and the ship navigation is met big stormy waves anchor and should do not rocked.Be equipped with the design of ground tackle (hawse pipe, anchor recess, anchor lip etc.) ship and make the experience that comparative maturity is all arranged for stem two topsides, the data of reference is also many, and anchor fluke can be close to planking after the ship of the type was weighed anchor, and anchor can not rock yet when navigation.The bower ship that compares chubbiness for the stem line style, normally oval-shaped cast steel anchor lip is installed by the hawse pipe at bow place, according to shipbuilding experience in the past, this traditional cast steel anchor procheilon structure is strained anchor cable when ship is weighed anchor after, only being at 2 between bohr anchor and the anchor lip contacts, real ship and draw anchor testing all to show adopts this cast steel anchor procheilon structure, even anchor cable tension back is also tended to produce the loosening of anchor and rock by ship navigation vibration.But for the high speed vessel of the thin ship type of stem line style point only the stem place have single bower equipment can reference data almost do not have, external problem for solving the upset of high speed vessel list bower and preventing to rock, be put on the deck bower fixing, so both occupied the stem floor space, not attractive in appearance again, this is a kind of helpless design.
Summary of the invention
