Abstract

PURPOSE:To save the labour of swing-out work of a broadside ladder by disposing a broadside ladder at the broadside in such a manner that the ladder can be turnably swung up and down through the center of the end part thereof in the perpendicular direction with respect to a boat body and attaching both lifting up/down winches and a stopper which can be retained upright at the broadside. CONSTITUTION:A broadside ladder 1 is disposed at the broadside in such a manner that the ladder can be turnably swung up and down through the center of the end part thereof in the perpendicular direction with respect to a boat body A. Both a stopper 2 which is held upright when it is folded at the broadside and winches lifting up and down the stopper 2 are attached to a boat construction B. The swing-out work of the broadside ladder 1 can be thereby automatically performed at the broadside by actuating the winches and unlocking the stopper. In addition, when the ladder is folded, the ladder is held upright on a deck, on account of which the folding space for the ladder can be saved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is an automatic swing-out gangway device fff IC t;! that aims to save labor in the work of swinging out a gangway. ] O [°Prior Art] The work of swinging out the gangway when a ship berths is done manually. That is, as shown in Figure 2, first the gangway (1) is lowered along the hull (A), and then the gangway (1) is lowered to shore 9 (C) K.
Once it is within the reach of a worker, the worker manually swings it out in the direction shown by the arrow.

[Problem that the invention seeks to solve]

Since the work of swinging out the heavy gangway (1) is done manually, the workers are forced to do hard labor, and as a result, they are forced to give up their hands unexpectedly during work, and the time required to create forms is reduced. There was a problem that it became long.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an automatic swing-out gangway device that automatically performs the swing-out operation on the ship side at the same time as the I5 lowering of the gangway.

[Means for solving problems]

FIG. 1 shows the configuration of the invention, and the invention is based on the
), a stopper (2), and a lifting device (3).

Gangway (1) r! It is pivotally supported on the side of the ship so that it can be raised and lowered at right angles to the hull (A) around its end.

The stopper (2) is used to lock the gangway (1) in an upright position when it is raised, and extends horizontally from the superstructure CB) of the hull (A).
1) is abutted toward its tip when it stands upright.

The elevating device (3) raises and lowers the gangway (1), and lifts the gangway (1) upward and locks it to the stopper (2).
) in an upright position. Such a device includes a hoisting and holding mechanism for the gangway (1) consisting of a cable attached to the tip side of the gangway (1) and a take-up winch that winds it up, and a lifting and holding mechanism for the gangway (1) near the shaft support end and the hull (A). ) or a strut ((2) with a springback mechanism of the gangway (1) consisting of nine springs installed on the tip side) is optimal.In this case, the cable is wound up with a winding winch. Pull the gunwale (1) 1! When the gunwale (1) comes into contact with the stopper (2) and is in an upright position, if you keep the tension on the cable, you can hold the ship in an upright position. Also, if no tension is applied to the cable, the elastic force of the spring will cause the gangway (1) to spring back outward,
After it begins to topple under its own weight, it can be lowered by unwinding the cable with a take-up winch. In addition, there is a crank t4 +? installed between the gangway (1) shaft support end and the hull (A). In addition to the 'J' and a hydraulic cylinder connected therebetween, it may also be composed of a motor or the like that is interlocked with the pivot portion of the gangway (1).

If the tip of the stopper (2) is made of a magnet, the elevating device (3) can more reliably hold the gangway (1). Also, if the stopper (2) is extended longer than the superstructure CB) so that the gangway (1) is held upright, or if the lead body (A) is tilted outward, Even if no spring is specifically provided as the elevating device (3), the gangway (1) can be lowered by its own weight when the tension of the cable is released. Even in that case, if a spring is further provided, the gunwale (1) can be reliably swung even if the hull (A) is unbalanced due to the cargo and is tilted to some extent, which is desirable as a configuration of the present invention. Become something. However, when the gunwale (1) is held tilted outward, if the gunwale (1) is kept upright, the maximum width of the hull (A) will be larger than the upper part of the hull (A). It is preferable that the gunwale (1) is telescopic, so that the gunwale (1) is retracted when standing upright.

[For production]

Normally, it is stopped by the stopper (2) by the lifting device (3).
Hold the ladder (1) upright on the hull (A).

Further, when the ship is berthed, the gangway (1) is lowered in a direction perpendicular to the ship's body (A) by means of a well e (3), and its lower end is used as a swamp on a quay or the like.

At this time, since it descends in the right angle direction, there is no need to carry out the conventional work of swinging out the gangway (1).At the time of departure, the gangway (1) is lifted up by the lifting device (3) and brought into contact with the stopper (2) to stand upright. 〇。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

FIG. 3 shows one embodiment of the present invention, which has a gangway (1G), a stopper (A), and a lifting device (A). ) when the ship approaches the berth, the gangway α (is the quay from which the ship attempts to lower itself).

The bracket Qυ is fixed to the gunwale αO and the side of the hull (A).
This causes the end of the shaft to explode, and the ship's hull (
It is invested in a state where it can only be lowered four times in the direction perpendicular to A).

The stopper 4 is formed of a pillar-shaped body or a plate-shaped body that extends horizontally from the upper side of the superstructure (B) of the hull (A).
'''C, the said gangway σO is raised and the said gangway [1
It has a structure that can lock the gangway αQ in an upright state when the vicinity of the tip of G comes into contact with the tip. The tip of the stopper is made up of an electromagnet (C), and its magnetic force can magnetize the area near the tip of the steel gangway to the stopper, allowing the elevator operator (described later) to maintain the upright position of the gangway αO. Holding can be performed more reliably.

The elevating device (a) is formed of a lifting and holding machine groove consisting of a pile (31) and a take-up winch (32) for winding it, and a springback machine groove consisting of a spring (33) 7). ing. The system (31) is connected at one end to the gangway σG tip connecting fitting (34) as shown in FIG.
At the other end, the winding winch (32) fixed to the upper part (B) of the hull (A) is used to wind up the wood (31). Then, by applying tension to the cable (31), you can keep the gunwale in an upright position. (33) i As shown in Fig. 5, the axis of the nine gunwales C1 () is supported by the bracket α.
Near the fulcrum aO? , fixed on the hull (A), with the origin (35)
It is provided between the four stopper protrusions (36), and
When the system (31) is loosened and no tension is applied, its elastic force swings the gangway αO outward.

In addition to the above-mentioned construction in non-implemented examples, as shown in Fig. 4, there is one wheel (300) for ground correction at the tip of the gangway αG.
are attached, and a landing limit switch (301) and a storage limit switch (30) are attached to both sides, respectively.
2) is provided. The landing limit switch (301) on the outside of the gangway αO is set so that when the gangway (1υ) descends and reaches the 8th shore, it is pressed by the quay (C) and turns off, causing the take-up winch (32) to unwind. It will stop automatically.In addition, the stopper (E) will prevent the gunwale Ou from being pulled by the limit switch (302) for retraction installed on the opposite side.
Fl is in contact with fl, [Fixed to the stopper side when standing up
When the switch striker (303) is pressed, the switch is turned off, and the winding of the winding winch (32) is automatically stopped.

The above-mentioned HIFIJ: is used in the following manner in the automatic swinging gangway device of the non-embodiment.

Normally, by abutting the tip of the gangway σ0 against the stopper 4 and applying tension to the take-up winch (32) to the cable (31), the gangway αO is held upright on the hull (A). Then, when docking at the quay (C) and swinging out the gunwale V, release the tension in i (31) and let the spring (33) spring apart the gunwale uO to the outside of the hull (A). After it begins to fall down due to its own weight, the take-up winch (32) is unwound and the gangway OQ is lowered.When the tip of the gangway CIO reaches the shore, the reservoir limit switch (301) is turned on and the take-up winch (32
) The unwinding of the cable (31) is stopped. When boarding is finished and it is time to set sail, when retracting the gangway αO, use the take-up winch (32) to pull up the cable (31) f, the take-up winch, and extend the gangway 00 to the upright position. It is brought into contact with stopper 4.

At this time, the storage limit switch (302) is pressed by the switch striker (303) and turned on, stopping the winding of the cable (31) of the winding winch (32). For offshore pressure use, as shown in Figure 6,
By setting the hinged stopper (400) near the outer shaft support of the gangway before swinging out, it is possible to keep this at a certain angle when swinging out the gangway.

〔Effect of the invention〕

The purpose of the present invention is to use the VIJ3 extending gangway device to lift out the bottom of the ditch as described above, and at the same time as the lifting and lowering described in Preamble 1, the ship can self-help by using power on the ship side. This has the excellent effect of eliminating the need to manually carry out each harvesting row, eliminating unforeseen man-hours during work, and shortening the working time. Since the ladder is stored in an upright position, it requires less space for installation, and it also has the advantage of being advantageous in terms of wave resistance since it is located at a high place.
