Problems solved by technology

Since the power that the gear can transmit is limited by the structural strength of the gear teeth, if the weight of the anchor chain to be retracted is too large, the teeth of the gear may be deformed or even broken, making the windlass invalid and unable to lock Anchor chains have great potential safety hazards and are prone to safety accidents

Embodiment 1

[0036] Embodiment 1: During emergency braking, the oil inlet loses pressure, and the pressure block moves axially outward under the action of the spring to discharge the hydraulic oil in the first sealing chamber, and at the same time, the second stepped surface of the end face and the second sealing chamber The fixed friction disc at the inner lower end contacts and continues to move outward against the elastic force of the wave spring, pushing the fixed friction disc and the dynamic friction disc to move axially until the friction assembly is completely compressed to achieve the purpose of braking or deceleration. In this embodiment , to drive the movement of the pressing block through the elastic component;

[0037] During normal operation (resetting), the hydraulic oil enters from the oil inlet. Under the pressure of the oil, the pressing block overcomes the spring force and moves axially inward. They are separated from each other under the action of the positioning steel ...

Embodiment 2

[0038] Embodiment 2. In this embodiment, another oil port is provided between the two pressure blocks. During emergency braking, the oil port enters oil, and the oil port 103 outputs oil. Under the action of pressure oil, the pressure block axially Outward movement, the second stepped surface of the end face is in contact with the fixed friction disc at the lower end of the second sealing cavity, and continues to move outward against the elastic force of the wave spring, pushing the fixed friction disc and the dynamic friction disc to move axially until the friction disc is completely compressed components, to achieve the purpose of braking or deceleration, in this embodiment, hydraulic oil is used to drive the briquetting block to move;

[0039] During normal operation (resetting), the hydraulic oil enters from the oil inlet and discharges the hydraulic oil between the two pressure blocks. Under the pressure of the oil, the pressure block overcomes the spring force and moves a...

Abstract

The invention provides an auxiliary device for an anchor machine for a ship. The auxiliary device comprises a shell, the shell is rotatably provided with a shaft sleeve, a pressing block is arranged in the shell in a sliding mode, the sliding direction of the pressing block is parallel to the axis of the shaft sleeve, the pressing block is provided with a first step surface and a second step surface which are perpendicular to the shaft sleeve, a third step surface and a fourth step surface are arranged in the shell, a first sealing cavity is formed between the first step surface and the thirdstep surface, a second sealing cavity is formed between the second step surface and the fourth step surface, an oil inlet is formed in the side wall of the first sealing cavity, a liquid inlet and a liquid outlet are formed in the side wall of the second sealing cavity, and a friction component is arranged in the second sealing cavity. The auxiliary device for the marine anchor machine is compactin structure, good in braking deceleration effect and high in stability.

Description

technical field [0001] The invention relates to a winch, in particular to an auxiliary device for a marine windlass. Background technique [0002] The windlass is a machine used to retract and release the anchor chain on the ship. It is an indispensable equipment on the ship. It is usually used in conjunction with the chain stopper. After the anchor chain is retracted, the chain stopper can hold the anchor chain to withstand the tension of the anchor chain. , so that the pulling force on the anchor chain is not transmitted to the windlass. The windlass mainly includes a chain wheel, a machine base and a power unit. The chain wheel is rotated and arranged on the machine base, and the power unit can drive the chain wheel to rotate. The power device of the windlass usually includes a power source and a gear pair. The power source includes a steam engine, an electric motor, a hydraulic motor, etc., and the power source transmits power to the anchor chain wheel through the gear ...
