Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a watertight device for a pontoon hatch cover.

Conventional configuration and problems thereof Normally, as shown in FIGS. 1 and 2, a plurality of pontoon hatch covers 1 on a cargo ship or the like are arranged adjacent to each other on a hatch 2, and In order to seal between the hatch covers 1 and 1, one of the pontoon hatch covers 1A
A gasket 3 is provided on the other pontoon hatch cover 1B, and a tightening cover 4 is provided on the other pontoon hatch cover 1B, which is tightened with a cleat or the like to maintain a sealed state such as liquid-tight or air-tight. Note that 5 is a chock provided on the outer surface of the pontoon hatch cover 1, and 6 is a positioning fitting provided on the upper surface of the hatch coaming 7 for guiding the chock 5. However, this method has the disadvantage that opening and closing of the pontoon hatch cover 1 can only be done in a fixed order. For example, in Fig. 2, when opening the hatch, the center hatch cover 1A can only be opened after removing both side hatch covers 1B and 1C, and when closing the hatch, the center hatch cover 1A must be opened first. Only after installation can the hatch covers 1B and 1C on both sides be installed. Additionally, if a large load is applied to the center hatch cover 1A, the hatch cover will deflect in the vertical direction and will no longer be able to maintain a sealed state, which inevitably results in drawbacks such as the need for a cleat between the hatch covers. Ta.

OBJECT OF THE INVENTION The object of the present invention is to provide a watertight device for a pontoon hatch cover that overcomes the above-mentioned conventional drawbacks.

Structure of the Invention In order to achieve the above object, the watertight device for a pontoon hatch cover of the present invention is a watertight device for sealing the gap between a plurality of pontoon hatch covers that are used in a row. The gutter has an arch-shaped gutter that protrudes along the opposing sides of the gutter, and a core that is held on the side surface of one of the pontoon hatch covers and is formed to cover both of the gutter from above and is provided on both side edges. It consists of a band that presses against the gutter to keep it watertight, and a tightening device that pulls the band downward and presses it against the upper surfaces of both gutters.

Embodiment and Operation An embodiment of the present invention will be described below with reference to FIGS. 3 to 8. Reference numeral 11 designates a plurality of pontoon hatch covers that are used by being arranged on the hatch coaming 12. Reference numeral 13 designates an arch-shaped gutter provided protrudingly along each opposing side surface of these pontoon hatch covers 11, and the side end portion thereof is formed into a spherical portion 13a that bulges upward. Reference numeral 14 denotes a long band that covers the upper surfaces of the gutters 13, 13 facing each other, as shown in FIG.
It consists of a long canvas 14b into which cores 14a made of rubber or the like are inserted into both sides. In addition, in FIG. 8, broken lines A indicate seams. Reference numeral 15 denotes a tightening device (for example, a turnbuckle) provided on the upper deck 16 immediately adjacent to the hatch coaming 12, and is used to pull the end of the band 14 and press the band 14 onto the gutters 13, 13. , is connected to a ring 14c provided at the end of the band 14. Note that the tightening device 15 may be provided on both sides of the hatch, or may be provided only on one side. When provided on one side, the other end of the band 14 is hooked and locked onto the upper deck 16, for example.
17 is a gasket installed on the hatch coaming 12, and the pontoon hatch cover 11,
In the portion between 11 and 11, a protrusion 17a that protrudes outward in a hook shape is specially formed. Further, the band 14 can be stored on the side of one of the pontoon hatch covers 11. That is, at a plurality of locations on one side of the band 14, attachment belt rings 18 are provided.
is provided, and a pontoon hatch cover 1 is provided.
Pins 19 are provided on one side for inserting and holding the mounting band ring 18, and furthermore, the band 14 can be hooked to hooks 20 provided at the upper side of one of the pontoon hatch covers 11 at multiple locations on the other side. A hook ring 21 is provided.

In the above configuration, when closing the hatch, first the pontoon hatch cover 11 is arranged on the hatch coaming 12. Next, remove the hook 21 and attach the band 14 to both gutters 1 as shown in FIG.
The band 14 is placed so as to cover the bands 3 and 13, and its both ends are pulled by the tightening device 15.
By pressing the cores 14a on both sides against the upper surfaces of the gutters 13, 13, the pontoon hatch covers 11, 1 can be securely closed.
It can maintain watertightness for 1 hour. Furthermore, the band 14 and the hatch combing 12 are different from each other.
Watertightness is maintained via the protrusion 17a of the gasket 17 provided on the side. Incidentally, when opening and closing the pontoon hatch cover 11, the band 14 may be locked to the hook 20 and stored as shown in FIG.

According to the configuration of the above embodiment, the gutters provided on the opposite sides of the pontoon hatch cover are covered from above with a band, and this band is pressed against the upper surface of the gutter by the tightening device to maintain watertightness between the pontoon hatch covers. As a result, the pontoon hatch cover can be opened and closed in random order, and even if a load is applied to one pontoon hatch cover and it bends in the vertical direction, the band can follow the gutter and maintain watertightness. Therefore, the cleat between the pontoon hatch covers, which was conventionally necessary, can be eliminated. Furthermore, since a core made of rubber etc. is inserted into both sides of the band,
Together with the spherical part of the gutter, the band can be prevented from coming off from the gutter, and it also works effectively to provide watertightness.

Effects of the Invention According to the above-mentioned configuration of the present invention, the gutters provided on the opposite sides of the pontoon hatch cover are covered with a band from above, and this band is pressed against the upper surface of the gutter by a tightening device to ensure watertightness between the pontoon hatch covers. This allows the pontoon hatch covers to be opened and closed in random order, and even if a load is applied to one pontoon hatch cover and it bends vertically, the band will follow the gutter to maintain watertightness. pontoon hatch covers, thereby eliminating the need for cleats between the pontoon hatch covers that were previously required.
