Automatic marine anchor gear brake device and brake method thereof

Abstract

The invention discloses an automatic marine windlass brake device and a brake method thereof. The brake device comprises a servo motor and a lead screw; a fixed plate is arranged on the anchor and mooring machine base, one end of a movable rod is hinged to the fixed plate through a pin shaft, the other end of the movable rod is provided with a threaded sliding sleeve allowing the lower end of a lead screw to penetrate through, and the lower end of a vertically-upwards-arranged hydraulic oil cylinder is hinged to the movable rod and located between the lead screw and the fixed plate. The end part of a piston extension rod of the hydraulic oil cylinder is hinged with one end of a brake rod through a pluggable pin shaft I; a connecting block is arranged on the side wall of a cylinder body of the hydraulic oil cylinder, a second pin shaft capable of being inserted and pulled is arranged on the connecting block, and the second pin shaft is movably connected with a second hole formed in the brake rod. The other end of the brake rod is hinged to the top end of the triangular seat; the brake band winding-in end is hinged to the lower portion of the triangular base, and the brake band winding-out end is connected with one end of the adjusting lead screw through a nut pin. A limiting seat is arranged on the brake rod, and the end, penetrating out of the limiting seat, of the adjusting lead screw is sleeved with a locking nut used for tensioning the brake band.

Description

technical field [0001] The invention relates to an automatic marine windlass braking device and a braking method thereof. Background technique [0002] Band brakes are widely used in marine machinery and equipment such as marine windlasses, winches, and towing winches. At present, the windlass brakes of ship anchoring equipment are usually purely manual or purely hydraulic band brakes. Pure manual operation has the disadvantage of high operating intensity, time-consuming and labor-intensive operation. When the operating speed of the operator cannot keep up with the speed of the anchor chain when the anchor is free, and once the crew does not operate properly, the anchor speed is too fast, and the chain will jump or even fall off. Seriously jeopardize the safety of crew and ships; separate pure hydraulic brakes, if the hydraulic system fails or fails, the brake system cannot be used normally, affecting the operation of the ship.

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned scheme ensures the speed stability of the windlass when it breaks down freely to a certain extent, and reduces the impact on the equipment; however, the above-mentioned braking system still has the situation of manual braking, and there is still a situation of pure manual operation by the staff, which is time-consuming and labor-intensive. The defect of unsafe operation; at the same time, during the manual operation of the crew, the operator can only use experience to operate the handwheel to control the brake and then control the anchoring speed, and cannot accurately judge the number of turns that need to be rotated by the handwheel according to the different loads of the windlass to achieve accuracy. Control the tightness of the brake pads to achieve the purpose of accurate braking; similarly, the above-mentioned patents do not specify the specific method of adjusting the oil pressure of the oil cylinder, and the oil cylinder cannot accurately adjust the extension of the piston rod according to the different loads of the windlass to achieve accurate braking.
