Flexible and adjustable marine anchor windlass brake device

Abstract

The invention discloses a flexible and adjustable marine anchor windlass brake device, and relates to the technical field of marine brake devices. The marine anchor windlass brake device comprises a first lever, a second lever, brake shoes, a cross bar piece, an inclined connecting arm, a first brake support and a second brake support; the first brake support is connected to one end of the first lever, and the cross bar piece is connected to the other end of the first lever; the cross bar piece is connected with the inclined connecting arm through a first cross stop block, one end of the second lever is angularly connected with the inclined connecting arm, and the other end of the second lever is connected with the second brake support; the brake shoes are separately arranged on the firstlever and the second lever, and the inner concave surfaces of the two brake shoes are oppositely arranged; and a brake screw is further arranged on the first cross stop block in a penetrating mode, abrake handwheel is installed on one end of the brake screw, a vertical connecting arm is connected to the other end of the brake screw, a rotating arm is connected to the vertical connecting arm, anda manual-pulling brake mechanism is further connected to the rotating arm. According to the flexible and adjustable marine anchor windlass brake device, semi-clutch can be realized, and stepless speedregulation from zero to the maximum speed of the rope winding or unwinding speed of a ship can be conveniently controlled.

Description

technical field [0001] The invention relates to the technical field of marine braking devices, in particular to a flexible and adjustable braking device for marine windlasses. Background technique [0002] The brake device of the marine winch is usually a band brake device. The braking and loosening of the brake in the belt brake device is realized by rotating the threaded handle, which is not flexible enough for operation, especially when it needs to be operated in a half-brake state. And the belt brake device uses a spring cylinder to achieve braking. The compression spring is installed in the cylinder barrel of the telescopic oil cylinder. The compression spring outputs the initial spring force to act on the piston rod to realize the braking of the brake device. However, the compression spring is prone to failure. If the compression spring fails, it is very inconvenient to repair or replace the compression spring and telescopic oil cylinder. So if the usual braking devic...

Problems solved by technology

[0002] The brake device of the marine winch is usually a belt brake device. The braking and release of the brake in the belt brake device are realized by rotating the threaded handle, which is not flexible enough for operation, especially when it needs to be operated in a half-brake state.

And the belt brake device uses a spring cylinder to achieve braking. The compression spring is installed in the cylinder barrel of the telescopic oil cylinder. The compression spring outputs the initial spring force to act on the piston rod to realize the braking of the brake device. However, the compression spring is prone to failure. If the compression spring fails, it is very inconvenient to repair or replace the compression spring and telescopic cylinder

Therefore, if the usual brake device is used, it will cause: 1. Difficulty in half-clutch operation, and difficulty in speed regulation and control when the speed is from zero to maximum speed; 2. The safety performance is not high, and maintenance or replacement is inconvenient
