Problems solved by technology

[0003] On the ship, the anchor chain needs to be retracted and released by the windlass, but the length of the release and retraction of the anchor chain cannot be known, and the release and retraction of the anchor chain cannot be well controlled, resulting in low operation efficiency of the anchor chain, especially When approaching the end of release and retraction, deceleration cannot be performed in advance, thus greatly improving the working strength of the braking device

Embodiment 1

[0032] Such as Figure 1~6 As shown, a marine windlass anchor chain length measurement device and method, including windlass 2, chain winding mechanism 3, guide mechanism 4 and auxiliary braking mechanism 6, anchor chain 7 passes through auxiliary braking mechanism 6, guiding mechanism 4 and the windlass 2 are wound up on the winding chain mechanism 3 at last, and the meter counting mechanism 5 is fixed on the guide mechanism 4, and the meter counting wheel 504 in the meter counting mechanism 5 leans against the anchor chain 7 to rotate;

[0033] A control system is also provided, and the control system is used to control the motor speed of the windlass 2, the motor speed of the winding chain mechanism 3, the brake hydraulic pressure of the windlass 2 and the brake hydraulic pressure of the auxiliary brake mechanism 6, and the meter wheel 504 is connected with The encoder 505 is electrically connected to the control system. With this structure, the anchor chain 7 leans agains...

Embodiment 2

[0042] Such as Figure 1~6 As shown, further description in conjunction with Embodiment 1: the meter counting mechanism 5 is installed in the anchorage state, the meter counting wheel 504 is leaned against the anchor chain 7, and the encoder 505 at this moment is displayed in the system to be cleared; , the movement of the anchor chain 7 will drive the meter wheel 504 to rotate, thereby converting the number of rotations into length through the encoder 505, thereby displaying the release length of the anchor chain 7 on the man-machine screen; after reaching the set release length, Gradually control the windlass brake to decelerate through the control system, reduce the release speed of the anchor chain 7, control and close the windlass 2 and the coiling chain mechanism 3 after approaching the set length, and at the same time use the windlass brake and auxiliary braking mechanism 6 to pair the anchor chain. 7 to perform braking, so that the anchor chain 7 reaches the set value ...

Abstract

The invention provides a marine anchor windlass anchor chain length measuring device and method, the marine anchor windlass anchor chain length measuring device comprises an anchor windlass, a chain winding mechanism, a guide mechanism and an auxiliary brake mechanism, an anchor chain sequentially passes through the auxiliary brake mechanism, the guide mechanism and the anchor windlass and is finally wound on the chain winding mechanism, and a meter counting mechanism is fixedly arranged on the guide mechanism. A meter counting wheel in the meter counting mechanism abuts against the anchor chain to rotate. The meter counting mechanism is installed on the guide mechanism, a meter counting wheel abuts against the anchor chain, the anchor chain moves to drive the meter counting wheel to rotate, and therefore the moving length of the anchor chain is well measured. When the anchor chain is released or withdrawn, the anchor chain can be decelerated in advance through a control system when the anchor chain is close to a set value, so that the working efficiency is greatly improved, and the working intensity of a braking system is reduced; and the windlass braking and the auxiliary braking mechanism perform dual braking, so that stable operation braking of the anchor chain is ensured.

Description

technical field [0001] The invention relates to the field of windlasses, in particular to a device and method for measuring the length of anchor chains of windlasses for ships. Background technique [0002] Anchor chain refers to a special chain that connects the anchor and the hull and transmits the grip of the anchor. It is often composed of anchor end links, middle links and end links. According to the structure of the chain link, it can be divided into two types: anchor chain with gear and anchor chain without gear. The strength of the former is greater than that of the latter; anchor chain can be divided into cast steel anchor chain and electric welding anchor chain according to the manufacturing method. The length of the anchor chain is in knots, and the standard length of each anchor chain is 27.5m. The internodes are connected with connecting links or connecting shackles. Usually, the chain length of the main anchor on each side of the 10,000-ton ship is about 12 ...
