Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a boarding and disembarking device for crew members or passengers to board or disembark from a ship.

[Prior art and its problems]

Conventionally, a gangway with one end attached to the ship's side has generally been used as a boarding/disembarking device that is spanned between a ship and a quay or tugboat for crew members or passengers to board or disembark from a ship. ing. However, such a gangway is difficult for workers to unwind and wind up the wire on the gangway in order to absorb changes in the water level of the ship at the quay, or vibrations caused by waves when transferring with a tugboat at sea. This required a lot of manpower and effort, hindering the automation and labor-saving of ships, and the work itself was difficult at sea, and it was also dangerous for crew members and passengers to board and disembark the ship.

[Purpose of the invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a boarding and disembarking device that allows crew members and passengers to board and disembark safely and easily without requiring any manpower or effort.

[Summary of the invention]

In this invention, gondolas are suspended at approximately equal intervals from an annular body rotatably supported on the ship's hull, and the gondolas are placed close to the movement area of the gondolas.
In addition, the platform is arranged to be movable up and down, and the position of the platform is adjusted to an appropriate height relative to the quay, and the slope of the step between the platform and the quay is set to the optimum condition for boarding and disembarking. It is characterized by the fact that crew members or passengers can board and disembark the ship safely and easily.

[Structure of the invention]

Next, the present invention will be explained with reference to the drawings. Fig. 1 is a conceptual diagram showing an embodiment of the boarding/disembarking device of the present invention with the ship's side plate removed, Fig. 2 is a vertical cross-sectional view of the center thereof, and Fig. 3 is a support structure for a gondola. FIG.

This boarding/disembarking device is accommodated and installed in a recess 1 formed on the ship side. On the side wall 1a of the recess 1,
Annular rails 2a and 2b are fixedly installed.
These rails 2a, 2b are arranged concentrically, the rail 2a having an inwardly opening groove 3a, and the rail 2b having an outwardly opening groove 3b. These rails 2a, 2b and side wall 1
An annular rotating body 4 is arranged between the a and the a.
Four horizontal arms 5 are installed at equal intervals on the outer surface of the rotating body 4. A roller 6 is rotatably supported on the arm 5.
are fitted into the grooves 3a, 3b of the rails 2a, 2b. Therefore, the rotating body 4 has rails 2a,
It will be rotatably supported along 2b.
Further, a gondola 8 is suspended from the arm 5 via a bearing 7. Furthermore, a gear 9 is formed on the outer peripheral surface of the rotating body 4, and this gear 9
Pinion 12 of motor 11 installed on upper deck 10
It meshes with the The drive of this motor 11 is controlled by a controller 13 also installed on the upper deck 10.

On the other hand, outside the gondola movement area in the recess 1 (second
On the right side in the figure, a platform 14 is arranged. As shown in FIG. 1, the platform 14 is supported by pillars 16 at both ends so as to be movable up and down via rollers 15.

Further, one end of a wire 17 is secured to both ends of the platform 14, and the other end of the wire 17 is wound around a pulley 18 that is pivotally supported at the upper end of the support column 16. A sprocket 19 is fixed to the shaft end of the pulley 18.
is linked via a chain 20 to a sprocket 22 of a motor 21 installed on the bottom wall 1b of the recess 1. Further, approximately at the center of the platform 14, one end of the step 23 is supported by a torque hinge 24, etc., and a roller 25 is installed on the lower surface of the free end of the step 23. In addition, in FIG. 1, the reference numeral 26 is a controller for the motor 21.

The operation of the boarding and disembarking device described above will be explained below.
At the same time, the configuration of this device will be explained in more detail.

When the controller 13 is operated to drive the motor 11, the pinion 12 is rotated accordingly. The rotational force of the pinion 12 is transmitted to the gear 9, and as a result, the rotating body 4 is rotated. As the rotating body 4 rotates, the arm 5 also moves along the annular rails 2a and 2b, and the gondola 8 also moves in the direction of the arrow while being suspended from the arm 5. The movement of the gondola 8 is stopped at an arbitrary position by operating the controller 13.

On the other hand, by operating the controller 26, the motor 21
When driven, the rotational force is applied to sprocket 2
2. It is transmitted to the pulley 18 via the chain 20 and sprocket 19, causing the pulley 18 to rotate in one direction. When the pulley 18 is rotated, the pulley 18
winds up the wire 17, by means of which the platform 14 is raised. The platform 14 is then stopped at an arbitrary position by the controller 26.

Now, if the ship approaches the berth at high tide, the controller 26 will cause the platform 14 to
The step 23 is positioned at the lowest position indicated by the solid line in FIG. Passengers disembarking the ship board the gondola 8 at the highest position in FIG. 1, and when the gondola 8 moves to the lowest position, they descend onto the platform 14 and disembark via step 23. In addition, passengers who boarded the ship from Step 23 to Platform 14,
Board Gondola 8, which is the lowest
When it reaches the top, it descends to the upper deck 10.

On the other hand, when the ship approaches the shore at low tide, the controller 26 switches the platform 14 to the first
It is located at the uppermost position indicated by the dashed line in FIG. Then, the step 23 is spanned over the quay 26 with an optimal inclination, as shown in FIG. In this case, the disembarking passengers board the top gondola 8 in Figure 1, and when the gondola 8 reaches the middle left position, the passenger steps onto the platform 1.
4, go down to the top, walk on the platform 14 to the center, and disembark via step 23. Passengers who boarded the ship through step 23 walk on the platform 14 and board the gondola 8 located on the right middle stage, and when the gondola 8 reaches the top level, they can descend to the upper deck 10. Bye.

Note that between high tide and low tide, the platform 14 is moved to the optimum position by the controller 26, and the gondola 8 is moved by the controller 13.
If the ship is stopped in line with the platform 14, boarding and disembarkation can be performed in the same manner as described above.

In the above embodiment, the gear 9 and pinion 12 formed on the rotary body 4 serve as driving means for the rotary body 4.
However, any mechanism for rotating the rotating body 4 may be used. The drive means for the platform 14 also includes a sprocket 22,
Chain 20, sprocket 19, pulley 18,
The power transmission mechanism is not limited to the wire 17 or the like. Further, the opening surface of the recess 1 formed on the ship side is closed by a door (not shown) during navigation.

[Effects of the Invention] As described in detail above, according to the boarding and disembarking device of the present invention, the steps can always be set at an optimal inclination, making boarding and disembarking extremely easy.
