Description

[Detailed Description of the Invention] The present invention relates to a sliding type gangway for ships, and in particular, an object thereof is to facilitate and smooth the operation of storing the gangway onto the hull of the ship, and to securely maintain the stowage position.

Another object of the present invention is to reduce the capacity of the winding drive body when storing the gangway, and to simplify the structure and make the design compact, thereby facilitating handling.

In the sliding type gangway, a guide device with diagonal rails is fixed on the hull in a direction that intersects with the side line, and an upper landing davit and a gunwale davit are slidably placed on the guide device, and one end is attached to the upper landing. Usually, the gangway to which the ship is pivoted is pulled up via the gangway davit, ropes, etc., and then the whole is slid onto the ship's hull via the guide device and stored, and the extension is performed by this reversing action.

An important issue with this sliding type of gangway is that since the length of the gangway is long, it is necessary to stabilize the stowage and make the stowage operation smooth.Also, the gangway must be protected from waves during the voyage. Moreover, since the period of storage is substantially longer than the period of use of the gangway, stability in storage is particularly required.

In the conventional guide device, the diagonal rail was substantially fixed on the ship's hull, so the capacity of the rope winding drive body was larger than necessary. Because it was a rail, it was unstable to store the gangway, and passengers getting on and off the train had great mental anxiety when using it.

In addition, a particularly big problem with the conventional device is that the operation for retracting the gangway is complicated, and the necessary number of rests are provided on the hull between the upper landing davit and the gunwale davit, and the gangway is placed on these. However, the gangway was essentially bent, making mounting difficult and requiring heavy physical labor.

The present invention was devised in view of the above points, and in particular, it solves all of the problems and defects of the conventional device described above by improving the guide device for each davit provided on the hull. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 to 3, two guide devices 2 are installed on the side of the hull 1 at a predetermined interval in the longitudinal direction of the ship.

) is rotatably connected to the upper part of a support stand 31 which is erected and fixed on the hull 1 via a pivot part 32.

The pivot part 32 is a pivot part 32 that pivots at least the guide rail 4 in the direction along the side line, and is illustrated as a pin body in the embodiment.

The guide rail 4 has wheels 33 provided on the davits 6 and 7.
The wheel 33 has a guide part 34 that fits into the guide part 3.
By rolling on the hull 1, each of the davits 1-6 and 7 can move freely in and out of the hull in a direction intersecting the side line, that is, at the hull side portion of the hull 1.

Note that it is desirable to provide wheel stoppers at both ends of the guide portion 34 of the guide rail 4.

The guide rail 4 is tiltable around the pivot portion 32 and can maintain its posture in the direction along the level surface. Therefore, the guide rail 4 and the fixed side, in the embodiment, the support base 31 is shown as a telescopic fluid cylinder. Both ends of the tilt drive body 35 are removably connected via pivot parts 36 and 37.

That is, as shown in FIG. 4, the guide rail is held fixed in a horizontal position by the tilting drive body 35, and from this position the drive 3
When the guide rail 4 is extended, the guide rail 4 is extended as shown by the chain line in Fig. 4.

Regulation is maintained by contacting the top.

Next, referring to FIGS. 5 to 10, the specific structure of the enshrinement body 30 is illustrated.

5 to 10, a support 41, which is an H-shaped member in the embodiment, is erected and fixed on the hull 1 via a base plate 40, and a hook 42A having a screw structure is attached to the top of the support 41 for operation. The body 42 is threaded.

Furthermore, a base 44, which is a T-shaped member in the embodiment, is pivotally attached to the upper part of the support 41 via a pin 43, and a stay 46 is attached to the outer tip of the base 44 via a pin 45. It is pivoted.

The lower part of the stay 46 is fixed to a slide body 47 provided on the hull 1 by means of a pin body 4B which can be freely inserted into and removed from the hull 1, alternately and selectively inside and outside the hull.

That is, in the embodiment, the slide body 47 has a dirt floor shape and is inclined upwardly toward the outside of the hull, and has pin insertion/extraction holes 4 inside and outside the hull.
9A, 49B, the lower part of the stay 46 is fitted into the slide body 47, and the lower part of the stay 46 is inserted into each insertion/extraction hole 49A, 4 of the slide body 47 via the pin body 4B with the chain body 48A.
9B, and when the stay 46 is fixed to the insertion/removal hole 49A, the base 44 is in a horizontal position.
When the stay 46 is fixed to the insertion/extraction hole 49B, the base 44
are each held in a posture tilted forward and downward around the pin 43.

A base 50 made of wood or the like is mounted on the top surface of the base 44 with screws 5.
A platform 51 made of wood or the like is fixed to the outside of the upper hull of the support 41 with screws 51A, and the storage gangway 10 placed on the resting body 30 is protected from damage etc. here. In order to ensure this placement, a rope 52 attached to the tip of the base 14 is hooked onto the hook 42A of the operating body 42, so that the operating body 42 can be tightened. .

The illustrated example described above is an embodiment of the present invention,
The present invention also includes the following embodiments.

A plurality of gangway davits 7 are installed along the side line, and guide devices 3 are provided on the hull corresponding to the installed gangway davits.

This case is particularly effective when the gangway 10 is long, and in this case, the tilting fulcrums of the guide devices 3 and 2 are positioned on a common axis.

A winding drive device 14 is installed on the hull 1 for pulling up the gangway and moving the entire ship body including the gunwale into and out of the hull, and the drive device 14 has a simple winding winch configuration.

Furthermore, the guide sheave device 24 of the 10th-pool 23, the 20th
- The guide sheave device 26 of the pull-up 25 is connected to both the guide devices 2 and 3.
The guide rails 4 and 5 are provided respectively.

This is desirable in that it is possible to guarantee accurate and smooth guidance of the ropes 23, 25 even if the guide rails 4, 5 are tilted; Even if the hull 1 is provided with guide sheave devices 24, 26, there is virtually no problem.

Finally, for example, a turnbuckle structure is employed as the tilting drive body 14 of the guide devices 2, 3, and the tilting drive body 14 is pivotally mounted between the guide rails 4, 5 and the hull 1.

Next, the operation of the illustrated example of the sliding gangway will be explained.

In FIG. 1, both the upper landing davit 6 and the gunwale davit 7 are extended out of the ship, and the gunwale 10 is in a used state in which it is pulled down around the pivot 11, and each davit 6.7 is shown in FIG.
In use, the ropes 23, 25 and 27 are held in a horizontal position by the guide rails 4 and 5 via the tilting drive body 14, as shown in FIG.

When changing from this usage state to the storage state shown in Figure 2,
If the prime mover 15 of the winding drive device 14 is an electric motor, it is sufficient to simply turn on the switch.

Then, each of the output shafts 17 and 18 of the differential device 16 has a differential characteristic in which the shaft with a smaller load (torque) rotates and the shaft with a larger load stops, so in the state shown in FIG. The winding drums 19 and 20 are stopped, and the winding drum 2
Only the 1.22 side rotates, and the gangway 10 is pulled up by winding the rope 22 around both drums 21.

That is, the lower side of the gangway 10 is pulled up using the pivot portion 11 relative to the upper landing 9 as a fulcrum, and the gangway 10 becomes horizontal.

When the gangway 10 is raised in this way, the load on the winding drum 21.22 is smaller than the load on the winding drum 19.20, so that the drum 19.2
0 rotates and moves each davit 6.7 in the direction of the arrow shown in Figure 4.
slides on the guide rails 4 and 5 through the transfer of the wheels 3B, and as a result, the entire ship, including the gangway 10, is completely stored inside the hull and placed on the base 44 of the emplacement body 30. During the voyage, the rope 52 of the enshrinement body 30 is tightened by the operating body 42 to retract the gunwale 10 more stably, and even if there is rolling due to waves or the like, the retracting and retention of the gunwale 10 is maintained.

Furthermore, by providing a plurality of encampments 30 on the hull at predetermined intervals in the longitudinal direction of the gunwale, even if the gunwale 10 is long and large, its deflection can be reduced.

Next, in order to obtain a usage form from this stored state, first loosen the operating body 42 and release the rope 52, then move the stay 46 of the enshrinement body 30 as shown by the chain line in Fig. 5, and switch the electric motor. The changeover causes the winding drum 19.20 to be reversed so that the rope 23.25 can be reeled.

On the other hand, by extending the tilt drive bodies 35 of the guide devices 2 and 3, the guide rails 4 and 5 are tilted about the pivot portion 32 as shown in FIG. 4.

As a result, the entire structure including the gangway 10 together with each davit 6.7 is moved by gravity in the direction of the arrow in FIG.
After each davit 6.7 has been moved out of the hull, each tilting drive 35 is retracted to maintain each guide rail 4, 5 in a horizontal position.

When the output shaft 17 comes out of the ship as shown in FIG. By drawing out the gangway 1u, the gangway 1u is lowered using the pivot portion 11 as a fulcrum.

In addition, when an emergency occurs on a ship,
As shown in FIG. 42, the davits 6, 7, etc. can be lifted up by retracting each tilting drive body 35 and stored in the hull by their own weight, and the bending of the gangway 10 is prevented during storage. Even when it is difficult to transfer to the mortuary 30 due to
As shown in FIG. 2, the guide rails 4 and 5 can be tilted by reducing the tilting drive body 35, thereby making it possible to smoothly transfer the guide rails 4 and 5 to the resting body 30.

The present invention is as described above, and has the following advantages compared to the conventional example.

Since the guide rails 4 and 5 of the guide devices 2 and 3 that guide the upper landing davit 6 and the gunwale davit 7 in a direction crossing the side line are tiltable and fixed, the gunwale 10 is long and bends when retracted from the use position. Even if there is a problem, the gangway 10 can be lifted and transferred to the resting body 30, and the rest operation becomes extremely easy.

In addition, guide rails 4 and 5 are used to move from the storage position to the use position.
By tilting the outside of the hull downward, each davit 6
．． 7 can be moved by gravity, which assists the capacity of the take-up drive device 14 and allows the drive device 14 to be made compact.
