Description

[Detailed description of the invention] The present invention relates to a side door device for a ship.

As shown in FIGS. 1 and 2, a conventional side door device for a ship is provided at a loading/unloading port opened from the berthed abdomen of the hull A to the deck 1, and is connected in half through an intermediate hinge 6B. The top hatch cover main body 2X and the side door main body 3X were designed to open and close via an opening/closing cylinder 4 using an end hinge 5 of the cover main body 2X as a base.

By the way, when a ship becomes larger and the height between the berthing position and the deck 1, where the cargo receiving plate 17 with the cylinder 18 is projected from the cargo elevator 19 provided on the hull A onto the quay B, increases, It is also necessary to lengthen the side door body 3X, but when using the loading/unloading door, the top hatch cover body 2
Since the side door body 3X and the side door body 3X must be stored in a folded state, the other top hatch cover body 2X must also be formed to have the same length.

Originally, the top hatch cover body 2X was provided because it was necessary to open the ceiling part during maintenance, inspection, and repair of the freight elevator 19.
Forming the cargo elevator 19 to a length longer than the ceiling area means that the hull deck 1 is made longer than the ceiling area of the cargo elevator 19.
This is uneconomical as it leaves valuable surface area idle.In addition, with this device, the top hatch cover body 2X and the side door body 3X are stored in a folded upright position, so they cannot be used in rainy days. There were problems such as the top being open and the cargo inside Hull A getting wet.

This invention was made to solve these problems, and even if the side door body becomes longer due to larger ships, the top hatch cover body can be made larger than the original ceiling area. To provide a side door device for a ship which is not necessary and in which the side door body plays the role of an eaves in rainy weather to prevent cargo inside the ship from getting wet.

Embodiments of the present invention will be described below based on the drawings.

First, to explain the structure, as shown in Fig. 3, the end hinge 5 of the hull deck 1 provided with a loading/unloading port.
The top hatch cover main body 2, which has a surface area large enough to cover the elevator ceiling, is arranged so that it can be opened and closed from a horizontal position to an upward vertical position via an opening/closing cylinder 4 arranged at the end of the deck 1. .

On the left and right hull decks 1 where the tips of the top hatch cover body 2 are located when the door is closed, there are
A gate-shaped hull post 7 is erected across the space, and an upper pulley 8 is attached to the center of the top surface. In addition, on both inner surfaces of the hull post 7, as shown in Fig. 4, a series of strip plates are arranged at parallel intervals, with the lower part open, the upper part closed, and the upper part positioned slightly toward the rear. A guide rail 11 formed to be bent is fixed so that its lower part is vertical. In addition, the top hatch cover body 2
A guide 12 having rearwardly tapered surfaces at the upper and lower ends is integrally attached.

Next, in the air space of the cargo entrance that coincides with the belly of the hull A, there is a side door main body 3 that has a surface area sufficient to cover the air space from the top hatch cover main body 2 whose tip is located directly below this to the lower end of the cargo entrance. is placed in an upright position. Further, the guide wheel 6 mounted somewhat above the intermediate position on both sides of the side door main body 3 is connected to the guide rail 11 described above.
It is fitted into the opening so that it can roll freely.

Furthermore, the tip of an opening/closing wire 10 connected to an opening/closing cylinder 9 disposed on the hull deck 1 via an intermediate pulley 15 and an upper pulley 8 of the hull post 7 is tied to the lower end of the side door body 3. .

A stopper 13 is provided at the tip of the top hatch cover body 2, and a hook-shaped end stopper 1 is provided at the position where the top surface reaches when the top hatch cover body 2 is opened in an upright position.
Further, a support pin 16 is provided on the outer side surface near the upper end of the guide rail 11 so that the tip of the pin can be inserted into the guide rail 11 and pulled back by operating a cylinder.

Next, the action will be explained.

When the loading/unloading entrance of Hull A is not used, the third
As shown by the solid line in the figure, a top hatch cover main body 2 is placed on the ceiling side of the entrance so as to cover the entire area of the ceiling. In addition, a side door main body 3 is vertically closed on the ship's belly side of the entrance with its top positioned below the tip of the top hatch cover main body 2, so that the cargo entrance can be completely sealed during voyage. Can be done.

When reaching the destination bay and unloading the cargo from inside the hull A, first push the top hatch cover body 2 upward by operating the cylinder 4, and the top hatch cover body 2 will move around the end hinge 5 as a fulcrum. Open the door until it is upright. In this case, the end stopper 14 engages and holds it in an upright position.

Next, when the cylinder 9 on the hull deck 1 is extended, the wire 1 is pulled through the pulleys 8 and 15.
The side door main body 3, whose lower end is fixed at 0, is lifted upward using the guide wheels 6 on both sides as fulcrums, as shown in FIG. At this time, since both guide wheels 6 are fitted into the guide rail 11, they move upward while rolling within the same rail 11.

From around the time when the guide wheel 6 reaches a position where the rail 11 is slightly bent backwards, a rearward traction force acts on the upper end of the side door body 3, but the guide 12 is waiting at this position. Therefore, the traction force to the rear is suppressed, and only the lower end is pulled forward little by little, but the whole can rise stably.

After this, both guide wheels 6 are moved to guide rail 1.
Once it reaches the top end of 1, it will remain in this position as it will no longer be able to rise any further since this top end is closed. Since the pulling operation of the wire 10 continues thereafter, the side door main body 3 turns horizontally using the guide wheel 6 as a fulcrum, and when it becomes completely horizontal, the wire 10 When the pulling operation is completed, the upper end of the side door body 3 also reaches the stopper 13 of the top hatch cover body 2, at which point it is fixed by, for example, a pin connection. As a result, the side door main body 3 can function as an eaves of the loading/unloading path leading to the quay B by maintaining a horizontal configuration in the area above the loading/unloading entrance.

When the side door body 3 is in a completely horizontal position, if the support pin 16 is projected directly below the guide wheel 6 by operating a separate cylinder, the side door body 3 will stably maintain a completely horizontal position. Can be done.

Next, when loading and unloading the cargo into and out of the hull A is completed and the door is to be closed, the door can be closed by performing the above-mentioned reverse operation. In other words, when the wire 10 is loosened after removing the support pin 16 and the stopper 13, the side door body 3 will move due to its own weight because the guide wheel 6 is the fulcrum and the center of gravity is acting largely toward the lower end of the front. It descends while rotating from a horizontal mode to a vertical mode around a guide wheel 6, and when the lower end reaches the bottom surface of the loading/unloading port and stops, the side door main body 3 closes the ship's side of the loading/unloading port.

Further, when the cylinder 4 is subsequently subjected to a traction operation, the top hatch cover body 2 is moved to the end hinge 5.
It descends using the
When it comes into contact with the top of the cargo opening, the top hatch cover body 2 can close the ceiling side of the cargo opening.

As explained above, in this invention, the top hatch cover body and the side door body are formed separately, so the top hatch cover body can be made small enough to cover the ceiling area of the loading/unloading entrance. In addition to making effective use of the valuable area of the hull deck 1, the side door body 3 acts as a canopy during rainy weather, which has the effect of preventing the cargo inside the hull from getting wet.
