Description

[Detailed Description of the Invention] The present invention relates to a horizontally retractable layer guide device that can be slid horizontally into the hold of a ship or the like.

As shown in FIGS. 1 to 4 showing conventional examples, a conventional horizontal retractable door 2 is an opening between a center column 3 and a ship side wall 4 provided between a deck 1a and a deck 1b of a ship. established in the department,
The opening is opened by sliding it in the direction of arrow A, and is stored in the 2' position shown by the dotted line.

As shown in FIG. 4, a groove 6 is provided above the door 2.
A drive rack 8 and a drive pinion 9 that mesh with the drive rack 8 are provided in the groove 20 parallel to the drive rack 8 . When the drive pinion 9 is rotated by the drive source 10 , the door 2 is supported by the wheels 15 . At the top and bottom of the door 2, there are gaskets that are raised and lowered by hydraulic cylinders 12 and are biased by springs 13 to press against the upper and lower structures. 14 is provided to be able to move up and down,
This ensures a tight seal against wind and rain from the outside.

This conventional horizontally retractable door 2 is provided with an appropriate number of guide rollers 7 at the top as shown in FIG. A groove 6 with sufficient depth is provided in the interior to take into account the deflection of the deck 1a, and the guide roller T runs within this groove 6, so this groove 6 can be used to adjust the position of the door 2 between the closed position and the open position. It must be continuous over the entire length.

Therefore, the door 2 of the center girder 5 shown in FIG.
Even if the hull continuous structure is installed in a direction intersecting the moving direction of the ship, a groove 6 for guiding the door 2 must be provided on its lower surface.

Providing this groove 6 in a continuous hull structure such as the center girder 5 has a limit on the depth of the groove 6 from the viewpoint of strength, and the provision of the groove 6 also causes stress concentration around it. This is extremely dangerous and problematic.

On the other hand, the groove 6 has the necessary depth considering the deflection of the lower surface of the deck 1a.
If a guide rail, etc. with a If the height is taken, it is necessary to increase the height between deck 1a and deck 1b.

Therefore, the present invention was devised to solve the above-mentioned conventional problems, and it is possible to reduce the effective height between the upper and lower decks without providing a groove in the continuous hull structure such as the center girder. The object of the present invention is to provide a guide device that can guide a horizontally retractable door without having to do so.

The horizontal retractable layer guide device according to the present invention which achieves the above object is provided with a vertically movable guide roller for preventing the door from falling over at the top of the door, which is biased in the upward direction. The guiding guide rail protrudes from the underside of the upper deck and is connected to the upper deck via a shallow groove provided at the lower end of the continuous structure of the hull that intersects the direction of movement, and an inclined portion that slopes upward from this shallow groove. It is characterized by comprising a deep groove portion continuous along the length.

First, before explaining the embodiment of the present invention, the height H of the decks 1a and 1b in the conventional example shown in FIG.
Indicates the dimension between the upper surface and the lower surface of the continuous hull structure that constitutes the upper deck 1a, and this dimension H is usually H = (effective minimum deck height) + (deflection under load of the upper deck 1a) + (manufacturing error during construction).

Hereinafter, the present invention will be explained with reference to FIGS. 5 and 6, which illustrate one embodiment of the invention.

The guide device of the present invention is applied to a door having almost the same configuration and function as the conventional horizontally retractable door 2 shown in FIGS. 1 to 4, and has the same parts as the conventional example. are shown with the same part number.

Providing a groove 6 like the conventional example 0) below the center girder 5, which is a continuous structure of the hull disposed in a direction intersecting the moving direction A of the door 2, causes concentrated stress around the groove 6, which is no longer a continuous structure. occurs, resulting in insufficient strength, which is undesirable in terms of hull structure. Therefore, in the present invention, the groove 6 for cutting out the center girder 5 is not provided in the lower part of the center girder 5 on the deck 1a. A guide rail 16 is provided directly at the lower end of the center girder 5.

However, if a stiff guide rail 16 is provided at the lower end of the center girder 5 that protrudes below the upper deck 1a as usual, the effective minimum deck height will be lowered by the height of the guide rail 16. be.

Therefore, in the present invention, the guide rail 16 is set at a height H between the decks.
Among the design conditions, the bending of the upper deck 1a under load can be omitted in the adjacent portions of the hull continuous structures such as the pillars 3 and the center girder 5, as shown in Fig. 6. The upper deck 1a is connected to the upper deck via a shallow groove section provided at a lower portion that has approximately the same depth as the deflection of the upper deck 1a under load, and an inclined section that slopes upward from the shallow groove section toward the lower surface of the upper deck 1a. It consists of a deep groove section continuous along the lower surface of the deck 1a, and the effective minimum deck height is ensured by forming the guide rail 16 located below the continuous hull structure into a shallow groove section.

Further, as shown in the embodiment of FIG. 6, the guide rail 16 is arranged so that the lower surface of the deep groove section that continues along the lower surface of the upper deck 1a is higher than the lower surface of the shallow groove section located below the center girder 5. When configured in this manner, there is an advantage that the maximum deck height can be ensured under the force of the deep groove of the guide rail 16.

On the other hand, a guide roller 7 provided at the top of the door 2 to prevent the door from falling is provided so as to be movable up and down with respect to a guide roller receiver 18 fixedly installed on the door 2.
A spring 17 is installed between the guide roller 7 and the guide roller receiver 18 for biasing the guide roller 7 so as to constantly push it upward in the depth direction of the guide rail 16. There is.

Therefore, in the guide device of the present invention, as shown in FIG.
The door 2 functions to prevent the door 2 from falling while moving up and down smoothly, and the door 2 is guided along the guide rail 16.

In this case, a driving pinion 9 meshing with the driving rack 8
Although it is necessary to make the door 2 movable up and down by the spring 21, such a machine is of course unnecessary if the door 2 is driven by a wire or the like.

In short, the horizontal retractable layered guide device of the present invention is provided with a vertically movable guide roller for preventing the door from falling over at the top of the door, and is biased in the upward direction. The guiding guide rail extends along the upper deck via a shallow groove provided at the lower end of the continuous structure of the hull that protrudes from the lower surface of the upper deck and intersects the moving direction of the door, and an inclined portion that slopes upward from this shallow groove. The guide roller at the top of the door is guided by a continuous deep groove, but by configuring the idle rail to be a shallow groove at the lower end of the continuous hull structure, the effective height between the decks can be ensured. .

Therefore, there is no need to provide a guide groove that cuts out a part of the continuous hull structure, which is originally intended to reinforce the deck, and the strength of the continuous hull structure can be maintained.

Moreover, since the guide rail does not impair continuity at the point where it intersects with the hull continuous structure, the set height between the decks can be changed by effectively utilizing the margin in the design conditions between the decks. It has the advantage of being able to provide a horizontally retractable door.
