Abstract

The invention discloses an anchor drop speed control system of an anchor windlass, and belongs to the field of marine machinery. The system comprises a hydraulic oil cylinder, a brake, a gear pump, a first one-way valve, a reversing valve, a pressure reducing valve and a one-way throttle valve, wherein an oil outlet of the hydraulic oil cylinder is communicated with an oil outlet of the system; an oil inlet of the first one-way valve is communicated with an oil inlet of the system; an oil outlet of the first one-way valve is communicated with an oil inlet of the reversing valve; an oil outlet of the reversing valve is communicated with a first oil port of the pressure reducing valve; an oil outlet of the reversing valve is communicated with the oil outlet of the system; a second oil port of the pressure reducing valve is communicated with a first oil port of the one-way throttle valve; a second oil port of the one-way throttle valve is communicated with an oil inlet of the hydraulic oil cylinder and an oil inlet of the gear pump respectively; an oil outlet of the gear pump is communicated with the oil outlet of the system; set pressure of the pressure reducing valve is greater than or equal to the pressure required for completely opening the hydraulic oil cylinder.

Description

technical field [0001] The invention relates to the field of ship machinery, in particular to an anchoring speed control system of a windlass. Background technique [0002] In the process of free anchoring, in order to prevent the anchor chain from falling at excessive speed under the action of its own gravity and damaging the windlass or the hull deck, the speed of free anchoring is often limited. [0003] Existing windlasses are equipped with brakes (such as band brakes or disc brakes), and windlasses rely on the frictional resistance provided by the brakes to achieve braking speed limit. [0004] The traditional windlass breaking down is manually controlled. According to the marks on the anchor chain and the operator's experience, the brakes are manually controlled to brake once every half of the anchor chain. Experience determines), then open the windlass brake, and so on until the anchoring process is completed. [0005] In the process of realizing the present inventi...
