Abstract

PURPOSE:To safely and speedily bring a ship alongside a quay by way of saving manpower and labour by furnishing a fender for a bow and a water jet as an L-shaped floating body structure turning means. CONSTITUTION:At the time when a ship 1 approaches toward a quay 01 at a certain angle, by adjusting length of a hydraulic cylinder 3 on the back surface of a fender 2 for a bow, the front surface of the fender 2 is changed to be at an angle orthogonal with the central line of the ship 1. Hereby, the ship 1 weakly hits the fender 2 on the bow from the front, absorbs an impulse by a spring 3' for cushioning on the back surface of the fender 2 and others, and the ship 1 is stopped. When the ship 1 stops, by turning an L-shaped floating body structure in the arrow direction around a supporting support 5 in the center with a jet stream by a water jet 10 by about 90 deg., holding a bow part against the quay 01 from the side and simultaneously, drawing a stern part toward the quay 01 by the water jet 6 and the like of the stern part of the ship 1, the ship 1 is brought alongside a pier. Consequently, it is possible to safely and speedily bring the ship 1 alongside the quay by way of saving manpower and labour without drawing the ship 1 by a mooring wire.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a docking device for an L-shaped quay of a ship.

[0002]

2. Description of the Related Art Ships are generally pulled to the quay by pulling them with mooring lines or pushing them with tugs. For this reason, many workers are required to berth and it takes time.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a berthing device for an L-shaped quay of a ship, which enables safe, prompt, labor-saving and labor-saving berthing without pulling the ship to the quay by mooring lines. The purpose is to do.

[0005]

To this end, the present invention relates to a device for docking a ship to an L-shaped quay, the left and right sides 1 of which the base ends are pivotally attached to the stepped portions of the L-shaped quay via vertical pins. A pair of bow hydraulic fenders supported by vertical pins at the tips of parallel hydraulic cylinders with cushion springs, each of which is capable of changing the inclination angle on the horizontal plane with respect to the step, and the vicinity of the outer corner of the step. A bow in which the central part is rotatably supported horizontally through a vertical pin at the tip of an L-shaped floating structure in which one end is horizontally rotatably loosely attached to the upper end of a support column, which is erected on the seabed It is characterized in that it is provided with an outer plate fender and a turning means attached to the L-shaped floating structure for turning the L-shaped floating structure around the support column.

[0006]

According to this structure, the following actions are performed. (1) When the ship is approaching the L-shaped quay, adjust the length of the pair of left and right hydraulic cylinders so that the angle of the fender faces the bow. When the bow comes into contact with the bow fender, the shock received by the bow fender is mitigated by the cushion spring, thereby stopping the ship. (2) At the berth of the ship, the L-shaped floating structure is swiveled about 90 ° around the supporting column with a water jet etc., and the outer shell of the bow is pushed from the side and at the same time the stern of the ship is equipped with a water jet etc. Abut the ship-side fender on the quay side. (3) Since the L-shaped floating structure is pivotally supported by the support columns so as to be able to move up and down, it is possible to automatically respond to changes in tide level.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall plan view thereof, in which FIG. 1 (A) shows a state before berthing and FIG. 1 (B) shows a state after berthing. . Figure 2
1A is a sectional view taken along the line AA of FIG. 1A and a plan view taken along the line BB thereof, and FIG. 3 is an overall side view of FIG. 1B.

In the above figure, 01 is an L-shaped quay and 2 is an L
It is a neutral buoyancy bow fender disposed on the step portion 02 of the character-shaped quay 01, and the bow fender 2 is the step portion 02.
Is supported by a pair of parallel left and right hydraulic cylinders obliquely provided on a horizontal plane and a cushion spring 3 ′ externally inserted therein. Here, the front end of each hydraulic cylinder 3 is pivotally attached to the inner surface of the bow fender 2 via a vertical pin hinge, and the rear end is pivotally attached to the inside of the recess of the step portion 02 of the quay via a vertical pin. The vertical pin is shown in Figure 1.
As shown in (B), they are arranged at positions forming four vertices of a substantially parallelogram.

Reference numeral 4 denotes an L-shaped floating structure, which is an L-shaped quay 01.
As shown in FIGS. 3 to 4, the floating structure structure supporting pillar 5 standing upright is obliquely inserted in the seabed at a position diagonally forward of the projecting corner of the projecting corner, and is freely inserted according to the vertical displacement of the sea surface. It is supported so as to be vertically movable and rotatable, and the central portion of the fender floating body 9 is rotatably supported on the outer end of the floating body 4 via a vertical pin about a vertical axis. A fender floating body 9 is pivotally supported at the tip of the L-shaped floating structure 4 so as to rotate about a vertical pin as a fulcrum, and a fender water jet 10 is provided at the rear end of the floating body. 10 is driven by a water jet pump (not shown).

As shown in FIG. 2, the water jet 10 uses a pump P to pump seawater sucked from the bottom of the floating structure 4.
When the floating body 4 is opened to the position shown by the broken line in FIG. 1 (B), it has a two-way switching valve 11 that changes the jet direction by 180 ° as shown by the solid line arrow or the broken line arrow. The switching valve 11 switches the jet direction.

In such a structure, first, FIG.
As shown in, when the ship 1 approaches the quay 01 at a certain angle, the lengths of the two hydraulic cylinders 3 mounted on the rear surface of the bow fender 2 are adjusted to adjust the front surface of the fender 2. To an angle orthogonal to the centerline of the ship 1. Here, the bow of the ship is weakly applied to the bow fender 2 from the front, and the shock is absorbed by the cushion springs 3 ′ and the like provided on the back of the bow fender 2 to stop the ship. When the ship 1 stops, the L-shaped floating structure 4
As shown in FIG. 3B, the water jet 10 swivels the support stanchion 5 in the jet flow counterclockwise to hold the bow from the side to the quay and at the same time as the stern of the ship 1. The stern is brought close to the quay 01 and berthed by the water jet 6 etc. attached to the section.

[0012]

According to this device, the following effects can be obtained.
By using two hydraulic cylinders, the angle of the fender can be adjusted to the incoming angle of the ship, and the cushion spring can be used to absorb the shock and stop the ship. In addition, pressing the floating structure from the side of the bow with a water jet,
Quickly berth the ship by equipping the stern with the water jet etc. In short, according to the present invention, in an apparatus for berthing a ship to an L-shaped quay,
The base ends of the parallel hydraulic cylinders with a pair of left and right cushion springs, whose base ends are pivotally attached to the step portions of the L-shaped quay, respectively, are supported via the vertical pins.
A bow fender capable of changing the inclination angle on the horizontal plane with respect to the step portion, and one end horizontally loosely attached to the upper end of the support column that is erected on the seabed near the outer end corner of the step portion. Of the L-shaped floating structure, the central part of which is supported rotatably horizontally through vertical pins, and the L-shaped floating structure attached to the L-shaped floating structure. By providing the structure with a turning means for turning the support pillar around the supporting column, it is possible to safely and promptly save labor and labor and to berth the ship without pulling the ship to the quay by mooring lines. The present invention is extremely useful industrially because a docking device for a quay is obtained.
