Disclosure of Invention

The invention aims to provide a hydraulic ship mooring machine, which aims to solve the problem of improving automation degree of mooring of a ship during berthing and solve the problem of completing self berthing of the ship without coordination of wharf personnel.

In order to achieve the purpose, the invention adopts the following technical scheme:

the invention discloses a hydraulic mooring winch for a ship. The mooring rope machine comprises an outward-extending oil cylinder, an extending oil cylinder, a downward-extending oil cylinder, a height adjusting oil cylinder and a mooring rope gripper. The hydraulic ship mooring winch realizes fixed installation by welding the main fixing block and the abduction oil cylinder fixing block on the ship body, and is stored in the ship body by controlling the abduction oil cylinder and the abduction oil cylinder when the mooring winch is not used. The outward-extending oil cylinder is used for controlling the whole mooring line machine to be sent out of the ship board, and the outward-swinging angle of the mooring line machine extending out of the ship board can be adjusted. One end of the downward-extending oil cylinder is connected with the extending oil cylinder, and the other end of the downward-extending oil cylinder is connected with the height adjusting oil cylinder and used for controlling the downward extension and the upward furling of the height adjusting oil cylinder. The tail end of the height adjusting oil cylinder is movably connected with a cable gripper and an electromagnetic gripper, and the telescopic height of the height adjusting oil cylinder can adjust the horizontal height of the cable gripper. And a hand grip buffer is arranged at the top of the cable hand grip and used for relieving impact force when the hand grip contacts the mooring bollard.

After the ship slowly approaches the wharf and enters the operation range of the mooring machine, a part of the cable head on the winding drum of the ship mooring machine is released, the cable head to be moored is placed into the cable gripper, and the cable is gripped by the electromagnetic gripper beside the cable gripper. And then operating the outward-extending oil cylinder to extend the mooring rope machine to the ship board, and operating the downward-extending oil cylinder to adjust the height adjusting oil cylinder to be in a vertical state after the mooring rope machine is extended. And simultaneously operating the abduction oil cylinder and the extension oil cylinder to accurately and definitely position the cable gripper right above the mooring bollard, and then operating the height adjusting oil cylinder to lower the cable gripper. When the top of the mooring rope pile touches the loosening claw rod in the mooring rope gripping device, the mooring rope gripping device automatically loosens and sleeves the mooring rope into the wharf mooring rope pile, and if the head of the mooring rope is correctly sleeved on the mooring rope pile, the electromagnetic gripping device beside the mooring rope gripping device is quickly loosened and the mooring rope machine is recovered. If the head of the mooring rope is not accurately sleeved on the mooring rope pile, the electromagnetic gripper is not loosened, the mooring rope is still firmly fixed on the electromagnetic gripper, the mooring rope machine is rapidly recovered, the head of the mooring rope is placed in the gripper of the mooring rope again, and then the mooring rope action is repeated.

The existing ship needs a plurality of wharf mooring personnel to cooperate when berthing the wharf, needs manpower to pull the mooring rope soaked in water in the mooring process, and is heavy after soaking in water. If the cable is placed in water too much, the cable is easily rolled into the propeller to break the propeller. By using the hydraulic mooring line machine for the ship, self mooring of the ship can be realized by operating the extension and retraction of a plurality of hydraulic oil cylinders, manpower output can be reduced, and mooring of the ship can be realized under the condition that wharf workers are not matched with mooring lines.

One end of the extension oil cylinder 2 is movably connected with the main fixed block 13 through an extension oil cylinder movable bearing 9, and the other end is a free movable end. The hydraulic mooring of the ship can be deployed out of the ship body or stored in the ship body by operating the extension and retraction of the extending oil cylinder 1.

The extension oil cylinder 2 is movably connected with the height adjusting oil cylinder 4 through a bearing 12, one end of the lower extension oil cylinder 3 is movably connected with the extension oil cylinder 2, the other end of the lower extension oil cylinder is movably connected with the height adjusting oil cylinder 4, and the height adjusting oil cylinder 4 can be operated to extend downwards or retract upwards by operating the extension of the lower extension oil cylinder 3. The tail end of the height adjusting oil cylinder 4 is movably connected with a cable gripper 5 and an electromagnetic gripper 7, and the height adjusting oil cylinder 4 can adjust the height of the cable gripper 5.

Fig. 2 shows an embodiment of the cable gripper 5. When the cable gripper 5 is positioned right above the mooring bollard 15, the height adjusting oil cylinder 4 is operated to enable the upper surface of the mooring bollard 15 to touch the loosening gripping rod 18 of the cable gripper 5, and after the loosening gripping rod 18 is touched, the cable gripper 5 automatically loosens and drops the cable, so that the cable is sleeved into the mooring bollard. After the cable gripper 5 is loosened, the electromagnetic gripper 7 also fixes the cable, and after the cable is confirmed to be correctly sleeved into the mooring bollard 15, the electromagnetic gripper 7 is operated to loosen the cable. If the cable is not properly inserted into the bollard 15, the cable is withdrawn by the electromagnetic gripper 7 and re-lashing is performed.

Fig. 3 shows a specific structure of the mechanical cable gripper 5. As shown in fig. 3, the mechanical cable gripper 5 consists of a gripper hook 6, a release lever 18, a release lever 19, and a bracket 24. The rod body of the loose-grip lever 19 is provided with a groove 21, and the loose-grip lever 19 is movably arranged on a bracket 24 through a bolt 22. The upper end of the release lever 19 is movably connected with the grab hook 6 through a bolt 23, and the other end of the release lever 19 sleeves a bolt 20 fixed on the release rod 18 into a groove 21 of the release lever.

Before the ship is berthed, a rope head to be tied is placed into the cable gripper 5, and the cable is clamped by the electromagnetic gripper 7 fixed on the height adjusting oil cylinder 4. When a ship is in a port, the mooring cable machine is unfolded outwards by operating the outward-extending oil cylinder 1, and then the downward-extending oil cylinder 3 is operated to unfold the height-adjusting oil cylinder 4 downwards. The outward swing angle of the mooring machine is controlled by operating the extension and contraction of the abduction cylinder 1, the distance of the cable gripper 5 extending from the side of the ship is controlled by operating the extension cylinder 2, and the cable gripper 5 is accurately positioned above the wharf mooring bollard 15 by jointly operating the abduction cylinder 1 and the extension cylinder 2, as shown in fig. 6. When the cable gripper 5 is positioned directly above the quay bollard 15, the height adjustment cylinder 4 is operated to bring the upper surface of the quay bollard 15 into contact with the release lever 18 of the cable gripper 5, as shown in fig. 7. After the release lever 18 is touched, the cable gripper 5 automatically releases and drops off the cable head so that the cable is looped into the quay bollard 15. After the cable gripper 5 is loosened, the electromagnetic gripper 7 fixed on the height adjusting oil cylinder 4 also fixes the cable, and after the cable is confirmed to be correctly sleeved into the wharf mooring bollard 15, the electromagnetic gripper 7 is operated to loosen the cable.
