Description

[0001] The present invention relates to a hydraulic winch driving device for a ship,

The present invention relates to an apparatus for driving a hydraulic winch used in a ship, and more particularly, to an eccentric shaft control system for a hydraulic motor, which can manually adjust the eccentricity of an eccentric shaft of a hydraulic motor according to a load condition, The present invention relates to a new type of hydraulic winch driving apparatus for a ship, which can reduce the amount of deflection and maintain the anchor elevating speed at a low speed.

In general, the ship is provided with an anchor for mooring at a specific point in the sea, and the anchor is lifted or pulled down by the operation of the winch with its anchor chain lifted.

A hydraulic motor 10 is provided in the driving device for driving the winch. The hydraulic motor 10 is operated in the large eccentric state or in the large eccentric state by the operation of the marine regulator 30 by controlling the operation of the control valve 20, The eccentricity of the eccentric shaft is adjusted (rotation radius is controlled) as in the small eccentric state, and the speed of lifting an anchor (not shown) is kept slow or maintained fast.

1 schematically shows a hydraulic circuit for a conventional hydraulic winch.

As shown in the figure, in the conventional hydraulic type winch, the eccentricity of the hydraulic motor 10 with respect to the eccentric shaft is adjusted while the regulator 30 is operated by the pressure fluid passing through the shuttle valve 71, The speed of lifting the anchor is adjusted to be fast or slow.

However, in the hydraulic winch drive apparatus according to the related art, when the winch is used, the load caused by the anchor chain decreases and the speed at which the anchor is lifted increases as the anchor rises. Thus, the anchor is moved to the bell mouth There is a problem that shock noise is generated and the damage is caused due to an increase in impact impact.

That is, when considering the load at the time of the first rise of the anchor, the eccentric shaft of the hydraulic motor 10 is kept in the eccentric state at the time of the first rise of the anchor. However, when the rise of the anchor is made more than a certain level, The eccentric shaft of the hydraulic motor 10 is shifted to the small eccentric state so that the eccentric shaft of the hydraulic motor 10 is kept in the small eccentric state despite the increase of the diameter of the wound portion due to the winding of the anchor chain, The speed increased over time.

Further, when the control valve 20 is positioned in the neutral state, as the pressure fluid supply to the hydraulic motor 10 is blocked, the anchor is deflected by the load of the anchor and the anchor chain, The eccentric shaft of the anchor 10 is kept in the small eccentric state, so that the amount of deflection of the anchor is further increased, and the product reliability is inevitably lowered.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hydraulic control apparatus capable of manually adjusting an eccentricity of an eccentric shaft of a hydraulic motor according to a load condition, And to reduce the amount of deflection due to the anchoring of the anchor, and to maintain the anchor elevating speed at a low speed.

This will be described in more detail below for each configuration.

First, the supply flow path 910 is a flow path for supplying a pressure fluid to a ship's hydraulic type winch drive apparatus (hereinafter referred to as " winch drive apparatus "), Respectively.

At this time, the supply passage 910 is connected to receive a pressure fluid stored in a hydraulic tank (not shown) by driving a hydraulic pump (not shown), and the outflow passage 920 is connected to a pressure fluid Is returned to the hydraulic tank.

Next, the hydraulic motor 100 is a device that operates a winch (not shown) while being driven by a pressure fluid supplied through the supply passage 910.

The hydraulic motor 100 is operated in a small eccentric or eccentric state by the operation of the hydraulic actuator 110, thereby elevating and lowering the anchor connected to the winch.

The hydraulic actuating unit 110 has a cylinder structure that adjusts the amount of eccentricity of the hydraulic motor 100 while receiving or discharging pressure fluid through the first hydraulic line 610 and the second hydraulic line 620, The first hydraulic line 610 is connected to a first space 111 for switching the hydraulic motor 100 of the hydraulic operation unit 110 to a large eccentric state, And is connected to a second space 112 for switching the hydraulic motor 100 to a small eccentric state.
At this time, the hydraulic motor 100 is configured such that each piston (not shown) located in a plurality of cylinders arranged in a radial direction is driven by a pressure fluid to rotate the eccentric shaft (not shown) A typical radial piston type motor used is such that the eccentric shaft is controlled by the hydraulic operating part 110 from the center of the motor. 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.

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 is operated to supply the gas.

Particularly, the control valve 200 is supplied to the third hydraulic line 630 or the fourth hydraulic line 640 even when the pressure fluid is supplied from the supply passage 910 at a neutral position thereof .

Next, the regulator 300 is a valve for changing the direction of providing the pressure fluid provided to the hydraulic actuating portion 110 of the hydraulic motor 100.

The regulator 300 supplies a part of the pressure fluid flowing along the third hydraulic line 630 and the fourth hydraulic line 640 through the first branch passage 650 and the second branch passage 660 And is selected and provided to each of the spaces 111 and 112 of the hydraulic operation unit 110 constituting the hydraulic motor 100.

The first branch passage 650 and the second branch passage 660 are connected to each other by a first connection passage 670 and the first connection passage 670 is connected to the bypass passage 400, And 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, And a second shuttle valve 720 for controlling the flow direction of the pressure fluid is further provided at a communicating portion between the bypass passage 400 and the bypass passage 400.

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.

The bypass flow path 400 is a path for guiding the pressure fluid supplied to the supply flow path 910 directly to the regulator 300 separately from the third hydraulic line 630 and the fourth hydraulic line 640, to be. That is, some of the pressure fluid supplied through the supply passage 910 by the bypass passage 400 is directly supplied to the hydraulic actuator 110 through the regulator 300 without passing through the control valve 200 .

In particular, in the embodiment of the present invention, the supply passage 910 is further provided with a pressure compensator 11, and one end of the bypass passage 400 is connected to the pressure compensator 11 To receive the pressurized fluid from the hydraulic inlet side thereof.

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 opening / closing lever 500 is a portion which is installed on the bypass passage 400 and opens / closes the bypass passage by manual operation.

That is, in the embodiment of the present invention, the eccentric shaft of the hydraulic motor 100 can be maintained in the large eccentric state regardless of the load during the lifting of the anchor due to the operation of the winch, so that as the anchor is elevated, And the control valve 200 is maintained in the neutral state, so that the hydraulic motor 100 can be supplied with the pressure fluid (i.e., The eccentric shaft of the hydraulic motor 100 can be maintained in the large eccentric state through the pressure fluid supply to the bypass passage 400 by the operation of the opening and closing lever 500, So that the phenomenon can be minimized.

Hereinafter, the operation of the winch drive apparatus according to the embodiment of the present invention described above will be described in more detail.

2 shows a state in which the control valve 200 is in a neutral state and the opening and closing lever 500 is also in a neutral state.

In this state, since the pressure fluid is not supplied to the hydraulic motor 100, the regulator 300 is also in a neutral state and the pressure fluid is not supplied to the hydraulic actuating part 110, The shaft is in a small eccentric state.

When the eccentric shaft of the hydraulic motor 100 is in the small eccentric state, the amount of deflection due to the weight of the anchor becomes larger than that in the large eccentric state.

Accordingly, in the neutral state of the control valve 200, the opening / closing lever 500 is operated as shown in FIG. 3 so that the pressure fluid can be supplied to the regulator 300.

When the operation of the on-off valve 500 is performed, the high-pressure fluid existing on the hydraulic inlet side of the pressure compensator 11 in the supply passage 910 passes through the opening / closing lever 500, 680 to the regulator 300 where some of the high pressure fluid is provided to switch the regulator 300 to a high load condition so that the pressure fluid that has passed through the regulator 300 is supplied to the first hydraulic line And is provided to the first space 111 for switching the eccentric shaft of the hydraulic motor 100 out of the hydraulic actuating part 110 to the eccentric state via the first clutch 610.

Accordingly, the eccentric shaft of the hydraulic motor 100 is switched to the large eccentric state, thereby minimizing deflection due to the weight of the anchor.

4 shows a state in which a pressure fluid is supplied to the hydraulic motor 100 by power supply to the control valve 200. [

In this case, the pressure fluid that has passed through the pressure compensator 11 through the supply passage 910 flows to the third hydraulic line 630 by the guidance of the control valve 200 and is then supplied to the hydraulic motor 100 The hydraulic motor 100 is driven.

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 with the influence of such a high load so that the pressure fluid is supplied to the first hydraulic line 610 because the load is sufficient at the beginning of the operation of the hydraulic motor 100. [ . As a result, the eccentric shaft of the hydraulic motor 100 is in a large eccentric state and the anchor is smoothly lifted.

When the lifting operation of the anchor is proceeded, the chain of the anchor is gradually wound on the winch, thereby reducing the load for lifting the anchor.

When the load is reduced, the regulator 300 is restored by reducing the load supplied to the regulator 300, and the first branch flow channel 650 and the first connection flow channel 670, The pressure fluid, which is sequentially passed through the second connection passage 680 and provided to the regulator 300, is supplied to the second hydraulic line 620. As a result, the eccentric shaft of the hydraulic motor 100 forms a small eccentric state, as shown in FIG.

However, if the eccentric shaft of the hydraulic motor 100 is continuously operated in a small eccentric state due to such a decrease in load, the speed at which the anchor is pulled up gradually increases, and the anchors strike the bell mouth of the ship Problems may arise.

Accordingly, when the load is reduced, the operator can operate the opening / closing lever 500 so that the regulator 300 can continuously maintain the large eccentric state.

6, the high-pressure fluid existing in the hydraulic oil inflow side of the pressure compensator 11 in the supply passage 910 is supplied to the bypass passage 400 via the open / close lever 500, Closing lever 500 through the bypass passage 400 and then supplied to the regulator 300. At this time, compared with the pressure fluid supplied through the second connection passage 680, the opening / closing lever 500 is rotated through the bypass passage 400 The second shuttle valve 720 blocks the flow of the pressure fluid flowing through the second connection passage 680 and the bypass passage 400 is connected to the second connection passage 680 via the bypass passage 400. [ Thereby guiding one pressure fluid to be supplied to the regulator 300.

As a result, the hydraulic hydraulic winch driving apparatus of the present invention includes an open / close lever 500 for manual operation, a bypass channel 400 for supplying pressure fluid to the regulator 300 by the operation of the open / close lever 500, By providing the shuttle valves 710 and 720 additionally, the eccentric shaft of the hydraulic motor 100 can be forcibly eccentrically eccentric so that the bell mouth can be prevented from being damaged due to an excessive lifting speed during lifting of the anchor So that the eccentric shaft of the hydraulic motor 100 can be maintained in the large eccentric state even when the control valve 200 is positioned in the neutral state, thereby preventing the occurrence of deflection due to the weight of the anchor.
