The hoser drums 52 are provided at a plurality of locations on the bow, the longitudinal direction of the hull, and the stern. The chain drum 51 and the forsa drum 52 at the bow are independently driven by switching the power of one hydraulic motor.

５２が駆動されている。FIG. 4 is a configuration diagram showing an example of a device for driving a chain drum and a hoser drum. In this device, the chain drum 51 requires a large amount of power while the hoser drum 52 requires a small amount of power.
In order to obtain greatly different power at 3, the chain drum 5
1 and a chain drum shaft 54,
A gear mechanism 56 for obtaining motive power for driving each of them is provided between the fork drum shaft 55 provided with.
The chain drum 51 or the hoser drum 52 is driven by selectively connecting the gear mechanism with the clutches 57 and 58.

る。Further, while the chain drum 51 only needs to be wound at a constant speed, the hoser drum 52 needs to wind up a slack mooring rope quickly, so in this example, a large-capacity, constant-speed driving force and The hydraulic motor 53 is constituted by a two-speed hydraulic motor capable of switching between a large capacity and a small capacity so that a small capacity and a high-speed driving force can be obtained.

There is an invention described in Japanese Patent Application Laid-Open No. 955, but in this invention, a two-speed hydraulic motor can automatically and continuously shift without changing the speed. It is not possible to switch the pressure motor to a small flow or a large flow.

たい。By the way, the required liquid amount of the hoser drum 52 is a small liquid of several tons to several tens tons (for example, 5 tons, 10 tons) for winding the mooring rope. The amount may be sufficient, but the chain drum 51
As the required liquid amount, a large force of several tens tons (for example, 30 tons) for winding the anchor is required, so that a large liquid amount is required. Also, when driving the hoser drum 52, it is desirable to reduce the "small" side capacity of the hydraulic motor (for example, 1/3 flow rate) in order to obtain high-speed rotation so as to enable high-speed rotation.

を制限した液量に規制する必要がある。On the other hand, in this type of hydraulic motor 53, the allowable maximum number of rotations for each capacity is specified, and therefore, when the chain drum 51 is driven in the state of the "small" side capacity thus determined, If the amount flows into the hydraulic motor, the hydraulic motor 53 will over rotate. for that reason,
When a large amount of fluid (required flow rate) is caused to flow into the hydraulic motor when driving the chain drum 51, it is necessary to prevent the hydraulic motor from having a "small" side capacity. That is, when the hoser drum is driven, it is necessary to regulate the amount of liquid flowing into the hydraulic motor to a limited amount.

う。[0008] However, at present, these operations are performed by individually performing the operation of tilting the operation lever and the operation of switching the valve, which is a complicated operation. As a countermeasure, it is conceivable to increase the “small” side capacity of the hydraulic motor to a capacity that does not cause a large over-rotation even if a required liquid amount (large liquid amount) of the chain drum 51 flows in. The use of a chain drum determines the small capacity when using a fora drum.Therefore, a large-capacity hydraulic pump or drive motor that can supply an unnecessarily large amount of liquid when using a fora drum is required. The above facilities are required.

ることができる。On the other hand, when the chain drum is driven, if the manual switching valve 30 as the switching means is switched to the chain drum side e, the control liquid is supplied from the branch passage 29 to the flow regulating valve 28 via the manual switching valve 34. Then, the flow regulating valve 28 is switched to the open side. Simultaneously with this operation, the control liquid supplied from the manual switching valve 30 to the capacity switching valve 27 via the passage 32 is shut off, so that the capacity switching valve 27 is switched to the release state by the spring 33. When the hydraulic fluid from the hydraulic pump 2 is switched by the directional control valve 4 and supplied to the two-speed hydraulic motor 7, the hydraulic fluid in the flow path 12 flows into the large capacity side port 16 of the capacity increasing / decreasing mechanism 14, The two-speed hydraulic motor 7 is switched to the large capacity side. In this state, the flow rate supplied from the flow path 3 is supplied at a flow rate suitable for the large flow rate side, so that the two-speed hydraulic motor 7 can be driven with a high driving force.

ることはない。Therefore, when the chain drum is driven, the flow control valve 28 is switched to the open state, and the capacity switching valve 2 is switched.
7 can be switched to the large-capacity side port to wind up the anchor chain with large power. When the hoser drum is driven, the flow rate regulating valve 28 is switched to the throttled state and the capacity switching valve 2 is switched.
Since the high-speed mooring rope can be wound by switching the port 7 to the small-capacity port, it is possible to easily set a setting suitable for each drum driving state. As a result, the two-speed hydraulic motor 7 does not allow a large amount of fluid to flow in a small capacity state, and therefore does not rotate the two-speed hydraulic motor 7 excessively.
