Hydraulic brake system of marine winch

Abstract

The invention relates to a hydraulic brake system of a marine winch. The hydraulic brake system comprises an oil pump (1), a filter (2), a one-way valve I (3), a one-way valve II (12), a throttling valve (9), a reversing valve I (7), a reversing valve II (11), an overflow valve I (4), an overflow valve II (10), an energy accumulator (5), a pressure switch (6) and an oil cylinder group (8). After passing the oil pump (1) and the filter (2), one part of oil returns to an oil tank through the overflow valve I (4), and the other part of the oil passes the one-way valve I (3), the energy accumulator (5), the pressure switch (6) and the throttling valve (9). A certain volume of pressure oil stores in the energy accumulator (5). The pressure switch (6) controls the pump to stop and start according to the pressure of the energy accumulator. The throttling valve (9) adjusts the pressure and flow fluctuation to guarantee that a brake works stably. The oil cylinder group (8), the reversing valve I (7) and the reversing valve II (11) form a semi-pressure brake loop which is used for preventing second sliding down and jittering during starting and stopping. The oil cylinder group (8) and the reversing valve II (11) form a pressure relief loop. When the winch works, the brake system is turned on. Actual application indicates that the hydraulic brake system is low in work energy consumption, high in work efficiency, and stable in winch ascending, descending and braking.

Description

technical field [0001] The invention belongs to the field of ship machinery and relates to a hydraulic brake system of a ship winch. Background technique [0002] When the hydraulic winch fixed on the hull is in operation, it shakes from side to side as the hull is subjected to waves; therefore, the stability and anti-interference ability of the hydraulic winch are relatively high. When the hydraulic brake system of the winch brakes, due to the pressure shock in the hydraulic system pipeline Or flow fluctuations cause excessive or insufficient braking force. Therefore, a hydraulic braking system for a marine winch is urgently needed to achieve precise and stable control of the pressure and flow of the braking system. Contents of the invention [0003] The problem to be solved by the present invention is to provide a hydraulic brake system of a marine winch, so that the hydraulic control system can realize accurate and stable control of the pressure and flow of the brake sy...
