The radius of rotation of the eccentric shaft is referred to as the eccentricity A state in which the radius of rotation of the eccentric shaft is large is referred to as a large eccentric state, and a state in which the radius of rotation is small is referred to as a small eccentric state.

The hydraulic motor 100 receives the pressure fluid from the supply passage 910 through the third hydraulic line 630 and the fourth hydraulic line 640 or receives the pressure fluid from the supply passage 910 Out.

The first branched flow channel 650 and the second branched flow channel 660 are connected to each other by a first connection channel 670 and the bypass channel 400 to be described later is connected to the first connection channel 670, A second connection passage 680 communicating with the second connection passage 680 is connected to supply the pressure fluid to the regulator 300 through the second connection passage 680.

A first shuttle valve 710 for controlling the flow direction of the pressure fluid is further provided at a connection portion between the first connection passage 670 and the branch passages 650 and 660, Is connected to the inflow channel.

Particularly, the regulator 300 is configured to change the direction of the pressure fluid supplied to the hydraulic operation portion 110 of the hydraulic motor 100 according to the load of the pressure fluid supplied through the branched flow paths 650 and 660 . That is, when the load acting on the hydraulic motor 100 is large as in the initial driving, the pressure fluid is supplied to the first hydraulic line 610 so that the eccentric shaft of the hydraulic motor 100 can be in the large eccentric state When the load applied to the hydraulic motor 100 is small, the pressure fluid is supplied to the second hydraulic line 620 so that the eccentric shaft of the hydraulic motor 100 can be in a small eccentric state.

Next, the bypass passage 400 guides the pressure fluid supplied to the supply passage 910 directly to the regulator 300 separately from the third hydraulic line 630 and the fourth hydraulic line 640 It is the euro. That is, a portion of the pressure fluid supplied through the supply passage 910 by the bypass passage 400 may be provided to the hydraulic actuator 110 through the regulator 300.

That is, since the hydraulic pressure inflow side of the pressure compensator 11 maintains a higher pressure state than the hydraulic pressure outflow side (the hydraulic pressure inflow side of the control valve) of the hydraulic pressure operating unit 110, So that the operation of the hydraulic operation unit 110 can be smoothly performed.

Next, the control valve 200 is a valve that controls the supply of pressure fluid to the hydraulic motor 100.

The control valve 200 is located at a portion where the supply passage 910 and the outflow passage 920 are connected to the third hydraulic line 630 and the fourth hydraulic line 640, The pressure fluid flowing through the supply passage 910 is selected as a hydraulic line among the third hydraulic line 630 and the fourth hydraulic line 640 connected to the hydraulic motor 100 according to the descending operation of the anchor And a direction switching valve that opens and closes the bypass flow path 400.

At this time, the bypass passage 400 is kept shut by the operation of the control valve 200, so that the bypass passage 400 is not allowed to flow to the pressure fluid.

In addition, some of the pressure fluid flowing along the third hydraulic line 630 passes through the first branch passage 650, the first connection passage 670 and the second connection passage 680 in order The regulator 300 is provided to the regulator 300 via the inflow path 310. Since the load is sufficient at the beginning of the operation of the hydraulic motor 100, the regulator 300 is affected by such a high load, Line < / RTI > As a result, the eccentric shaft of the hydraulic motor 100 is in a large eccentric state and the anchor is smoothly lifted.

The hydraulic hydraulic winch drive system of the present invention is provided with the hydraulic motor 100 through the additional provision of the two shuttle valves 710 and 720 and the relief valve 730 and the bypass flow path 400 for supplying the pressure fluid directly to the regulator 300.
