Abstract
Description
[0001] The present invention relates to an apparatus for driving a hydraulic winch used in a ship, and more particularly, to an eccentric adjustment of a hydraulic motor manually according to a load condition, thereby reducing an amount of deflection of an anchor And an elevating speed of the anchor can be maintained 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

As shown in the figure, in the conventional hydraulic type winch, the eccentricity of the
However, in the hydraulic winch drive apparatus according to the related art, when the winch is used, the load caused by the anchor chain is reduced and the speed at which the anchor is lifted increases as the anchor is used. Thus, the anchor is moved to the ball mouse 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
Further, when the
SUMMARY OF THE INVENTION It is an object of the present invention to reduce the amount of deflection even when the control valve is in the neutral state by enabling the eccentric adjustment of the hydraulic motor manually according to the load condition. And to provide a hydraulic type winch drive apparatus for a ship according to a new form in which an elevator speed of an anchor can be maintained at a low speed.
According to an aspect of the present invention, there is provided an apparatus for driving a hydraulic winch according to the present invention, comprising: a feed channel for guiding an inflow flow of a pressurized fluid and an outflow channel for guiding an outflow flow of the pressurized fluid; A hydraulic motor that operates the winch while being driven by the pressure fluid supplied through the supply passage and operates in a small eccentric or eccentric state by the operation of the hydraulic operation portion; A control valve for controlling that the pressure fluid flowing through the supply passage is supplied to the hydraulic motor; A regulator for changing a providing direction of the pressure fluid provided to the hydraulic operation portion of the hydraulic motor; A bypass channel for guiding a portion of the pressure fluid supplied through the supply channel to be supplied to the hydraulic operation unit through the regulator directly without passing through the control valve and guiding the portion to be supplied to a portion for operation of the regulator; And an opening / closing lever that is installed on the bypass flow path and opens / closes the bypass flow path by manual operation.
Here, the supply passage further includes a pressure compensator, and the bypass passage is connected to receive the pressure fluid from the hydraulic inlet side of the pressure compensator in the supply passage.
The hydraulic motor is configured to receive the pressure fluid from the supply passage through two flow paths through which the pressure fluid is supplied or recovered. In the two flow paths connected to the hydraulic motor, the first branch flow passage and the second branch flow passage are connected A portion of the pressure fluid is supplied to the regulator through the branched flow paths and the direction of the pressure fluid supplied to the hydraulic operation portion is changed according to a load of the pressure fluid supplied through the branch flow paths. .
The first branch passage and the second branch passage are connected to each other by a first coupling passage, and a second coupling passage communicating with the bypass passage is connected to the first coupling passage, To the regulator.
In addition, a first shuttle valve for controlling the flow direction of the pressure fluid is further provided at a connection portion between the first connection passage and each branch passage, and a flow of the pressure fluid is provided at a connection portion between the second connection passage and the bypass passage. And a second shuttle valve for controlling the direction of the second shuttle valve.
The hydraulic hydraulic winch drive apparatus of the present invention as described above has the following features: (1) an open / close lever for manual operation; (2) a bypass flow path for supplying pressure fluid to the regulator by the operation of the open / close lever; So that it is possible to prevent the impact of the ball mouse due to an increase in the excessive lifting speed during lifting of the anchor.
Furthermore, even when the control valve is positioned in the neutral state, the hydraulic motor can maintain the large eccentric state, thereby preventing the occurrence of deflection due to the weight of the anchor.
