Embodiment 2

[0039] Further, adopt the marine towing winch transmission device controlled by the hydraulic system, it comprises two-way hydraulic motor 19, wherein the output shaft of one two-way hydraulic motor 19 is connected with the first sun gear 28 through the first coupling 27; The output shaft of the hydraulic motor 19 is connected with the second sun gear 30 through the second coupling 29, and the second sun gear 30 is engaged with the planetary gear 32 for transmission, and the planetary gear 32 is decelerated with the planetary gear through the third coupling 31 The motor 26 is connected, and the output shaft of the planetary reducer 26 is connected with the rotating shaft of the reel 25 to transmit torque.

[0040] Further, in the marine towing winch transmission device, the third coupling 31 is connected with a brake cylinder 20, and the brake cylinder 20 is connected to The second shuttle valve 11 is connected.

[0041] Further, the marine towing winch transmission device, t...

Embodiment 3

[0043] The method for controlling the transmission device of a marine towing winch using the hydraulic control system comprises the following steps:

[0044] In the first step, the hydraulic winch puts the heavy object in the normal operation mode. Once the heavy object is lowered into the water, the pressure setting level is reduced through the adjustable pressure valve 17. In this mode, when the load on the hydraulic winch is higher than the pressure When setting the level, the cable is in the state of unwinding, and when the load of the winch is less than the pressure setting, the cable is retracted;

[0045] In the second step, when the system is in the deployment condition, the DT2 of the three-position four-way reversing valve 7 is energized, the hydraulic motor 19 rotates forward, and the reel 25 is driven forward by the planetary reducer 26 to rotate forward, and the load can be put down;

[0046] In the third step, when the system is in the deploying condition, DT1 of...

Abstract

The invention relates to a hydraulic control system for a ship traction winch, a transmission device and a control method for ocean traction, lifting and load collection and release. The hydraulic control system comprises a hydraulic pump, a hydraulic motor, a speed reducer, a drum, a brake oil cylinder, a stopper oil cylinder, a control valve set, an auxiliary element and a pipeline. In a hydraulic winch system, an adjustable pressure overflow valve is embedded; the working pressure of the overflow valve can be set according to change of sea conditions; and the pressure acted on the hydraulic motor is limited, so that a cable is always located in a proper tensioning state, and the wave compensation capacity is achieved. The hydraulic control system can largely reduce the change of tension in the cable to adapt to different wave requirements, can be used for normal operation, can realize control of constant tension, guarantees stable and safe load collection and release operation, and can effectively improve the operation capacity of the whole winch under complex ocean environment.

Description

technical field [0001] The invention relates to a hydraulic control system of a marine towing winch, a transmission device and a control method, in particular to a hydraulic control system of a winch used in sea conditions for compensating tension changes of tow cables. Background technique [0002] The towing winch is the most important dragging or marine cargo component on a ship. Sometimes under harsh marine environmental conditions, the ship will roll, pitch, heave and heave, and the tension in the cable is prone to sudden changes. If the tension in the cable is too high, it is easy to cause the cable to break; if the tension of the cable is too small, the cable will become loose and twisted, and the load will easily collide with the hull, causing damage to the equipment. If the above phenomenon occurs, the movement of the hull will seriously affect the normal operation of the marine winch in the ocean, and even make normal hauling or ocean lifting extremely complicated ...
