Description

  The present invention relates to a mooring device used when mooring a ship to a quay or the like.

When berthing a ship on a quay or the like, as shown in Japanese Patent Application Laid-Open No. 2004-17690, two mooring ropes (mooring lines) are entangled with four mooring bits on the quay side from the bow and stern respectively. Generally, a method of winding the rope while adjusting the tension of the rope reduces the distance from the quay and moves to the desired position while moving in the front-rear direction.
In order to perform these operations, the ship's bow and stern are equipped with drum-type winches and are generally called mooring devices. Depending on the situation, the number of ropes may be further increased, or the tension may be utilized by throwing offshore.

  The general structure of a bow mooring device installed on the starboard and port side of the bow is equipped with two rope reels and one drawing wheel on the outer periphery of the drive shaft that rotates using hydraulic pressure as a power source. A meshing clutch that fits and disengages by operating a manual clutch lever to the left and right and a band brake that operates by turning a hand-operated brake handle are mounted. There is a drive operation lever for changing the hydraulic oil passage for rotating the drive shaft, and the rotation direction and speed of the drive shaft can be controlled by operating this lever back and forth. Although many stern mooring devices do not have a drawing wheel, they have almost the same structure as a bow mooring device.

  Next, the operation procedure to drive the necessary rope reel or drawing wheel will be explained. At the end of the operation of the mooring device, all the brakes are normally operated. It is effective. First, in order to engage the clutch of the rope reel or chainring wheel to be driven, the drive operation lever is operated and the drive shaft is gently turned.When the clutch teeth come into meshing position, the clutch lever is operated and the clutch is engaged. Put in. After confirming that the clutch is engaged, immediately return the drive lever to neutral to prevent it from rotating while the brakes are applied. Then turn the brake handle to release the brake. After these series of operations, the necessary rope reel or drawing wheel can be driven by operating the drive operation lever.

  On the other hand, when releasing the clutch of each rope reel and drawing wheel, turn the brake handle of the corresponding rope reel or anchoring wheel to apply the brake and operate the drive operation lever to operate the drive shaft immediately before. While slightly turning in the opposite direction, apply a force in the direction to release the clutch lever at the same time, and return the drive operation lever to neutral when the clutch is released.

The operation of operating the mooring device in this way requires a series of simultaneous operations or simultaneous operations of the drive operation lever, clutch lever and brake handle.
JP2004-17690

However, in the conventional mooring device, since the drive operation lever, the clutch lever and the brake handle are structurally separated from each other, a plurality of workers (2 to 3 persons) stand at the position of each lever, Operating while signaling each other. For this reason, it is necessary for a plurality of workers to operate the drive operation lever, the clutch lever, and the brake handle in a timely manner. If the operation linkage is poor, an accident due to an erroneous operation may occur.
In addition, an operator who operates the drive operation lever must operate the drive operation lever when operating any rope reel or anchoring wheel, but the clutch lever and brake handle of each rope reel or anchoring wheel must be operated. The operator is only required to activate the rope reel or anchoring wheel that he / she operates, and does nothing when other operators are operating other rope reels or anchoring wheels. The work efficiency is very poor.
Accordingly, an object of the present invention is to obtain a mooring device having a simple configuration in which one operator can operate each rope reel or anchoring wheel.

Operation is possible if one person is placed.

  When operating a mooring device, it was usually necessary to operate by two or three people except for a signal person, but by installing this device, it can be operated intensively by one person, improving safety and work efficiency. In addition, the effect of saving labor can be realized at low cost.

  The present invention is characterized in that a remote control device for operating a mooring device is realized by using a simple mechanical coupling mechanism, and the following is an example thereof.

As one embodiment of the device of the present invention, there are four sets of mooring devices, one set each on the bow and stern side of the ship, and the configuration of the mooring device on the bow side consists of two rope reels and anchoring wheels, The stern side is composed of two rope reels, and all the mooring devices are attached with the remote control device.
FIG. 1 is a plan view of a bow port mooring machine. FIG. 2 is a left side view thereof. FIG. 3 is a front view of a state where the remote control device is connected to the drive operation lever. FIG. 4 is a plan view for explaining the operation of berthing a ship using a mooring device. FIG. 5 is a plan view showing a moored state after berthing.

  First, the structure of the mooring apparatus will be described. Reference numeral 1 denotes a hydraulic motor, which is controlled by a hydraulic control valve 10 having a drive operation lever 14 to rotate the drive shaft 2 via the speed reducer 3. Transmission and disconnection of power to the rope reels 5a and 5b and the chain wheel 4 are performed by engaging and disengaging the clutches 7a, 7b and 7c by operating the clutch operation levers 6a, 6b and 6c, respectively. Also, brakes 9a, 9b and 9c which are operated by operating the brake operation handles 8a, 8b and 8c are mounted on the rope reels 5a and 5b and the anchoring wheel 4, respectively. Further, a remote control operation lever 12 having the same shape as the drive operation lever 14 is provided in the vicinity of the clutch operation lever 6a and the brake operation handle 8a, and the drive operation lever 14 and the remote control operation are performed by a connecting rod 13 supported by the bearing 11. It is mechanically connected as shown in FIG. 3 so that the lever 12 is interlocked.

  Next, a procedure for berthing a ship while operating the mooring apparatus will be described. When a ship wants to berth at a designated quay, it will approach by shore or on the assistance of a tug boat from the quay to several tens of meters offshore. From there, the mooring device of the ship is used, but a total of four ropes are entangled with the mooring bit on the quay as shown in FIG. The method of transporting the tip of the rope to the quay is by using a small boat or by throwing a small guide rope from the vessel to the quay and pulling it manually by a worker on the quay side. At this time, the rope reel brake of the mooring machine on the ship side is released, and the clutch is in a disengaged state, that is, a free state, so that the pulling operation on the quay can be performed lightly and quickly. When the four ropes are entangled with the mooring bit, the ship is brought closer to the quay by operating the mooring device on the ship side. As for the personnel assignment of the ship, there is one general conductor on the bridge. There are one signal person and one operator each on the bow side and stern side. Each mooring machine is fitted with a rope reel clutch with the rope connected to the quay under the direction of the general conductor, and the rope is wound according to the instruction of the signal person. The operator is located at the center of the starboard and port aircraft, and each drive operation lever is within the reach of both hands, so that both the starboard and port aircraft can be freely controlled by one person as instructed by the signal person. By winding up while adjusting the tension of the four ropes in this way, the distance from the quay can be shortened while keeping the hull parallel to the quay, and it is also possible to move in the front-rear direction and berth to the target point.

  In order to further increase mooring power after berthing to the target point, it is common to feed out the rope wound on another rope reel, entangle it with the same mooring bit, and apply the same tension to a total of eight ropes as shown in FIG. It is. At this time, the necessary operation in the mooring device is to apply the brake of the rope reel that was first driven, disengage the clutch, engage the clutch of the adjacent rope reel, and then attach the rope reel as instructed by the signal person. Wind it up. The rope reel drive may be switched several times for the final adjustment of the rope tension.

  In such an operation, when there is no remote control device, two or three operators are usually required to perform a necessary series of operations. However, by adding a remote control device, one or This system enables one person to perform the necessary series of operations when driving the rope reels of the two mooring devices provided side by side.

  The work area is useful in that a safe work floor is provided between the operation tools so that the operator can perform all operations with a safe minimum linear movement.

  By installing the apparatus of the present invention, safety and work efficiency can be improved and labor can be saved. Further, the remote control device is advantageous in terms of cost because it achieves this by using a simple mechanical coupling mechanism without using a device such as a hydraulic mechanism or an electric device.
