Abstract

(57) [Summary] [PROBLEMS] To seal the inside and outside of the inside and outside with packing and a compression bar, and to provide a drain pipe and a drain valve as a countermeasure for water leakage. The hatch cover has a problem that the hatch cover is elastically deformed, water enters between the combing ears and the compression bar from a gap caused by twisting, and the water enters the hold due to the sway of the hull. SOLUTION: As a countermeasure against stormy weather, a hatch combing 2 and a hatch cover 3 penetrate between a combing ear 5 and a compression bar 6 due to torsion due to elastic deformation. The water is to be discharged from the drain pipe 16 without leaking.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to hatch combing of a hatch (holding hole) for cargo provided in a rectangular shape on an upper deck and a device for preventing water leakage of a hatch cover.

[0002]

[Prior art]

 Conventionally, as shown in FIG. 2, a hatch H for several cargoes is provided on an upper deck 31, and a hatch combing 32 is erected in a rectangular shape at an edge of the hatch H, as shown in FIG. A hatch cover 33 divided into several pieces serves as a cover on the upper part of the hatch combing 32.

A fixed width combing top 34 is welded to the upper outer periphery of the hatch combing 32 except for a combing ear 35 at the upper end of the hatch combing 32.

Further, a compression bar (pressure bar) 36 is provided over the entire circumference of the combing top 34 at a predetermined position from the edge of the hatch combing 32.

In addition, two rails 37 are laid on the combing top 34 in the direction of the ship.

The hatch cover 33 forms a box body with a cover top plate 38, a cover ceiling 39, and four cover side plates 40, and a packing gutter 41 is provided at a peripheral end of the cover ceiling 39. At 41, a packing 42 made of synthetic rubber was fitted.

[0007] In addition, a wheel mounting arm 43 extends from both sides of the hatch cover 33, and two wheels 44 are pivotally mounted on the rails 37. The rider rides on the rails 37, and the hatch cover 33 moves in the vertical direction of the hull. It was like.

When the hatch cover 33 moves to a predetermined position, the wheel 44 falls into the depression of the rail 37, and the packing 42 of the hatch cover 33 is installed so as to hit the compression bar 36. The hatch cover 33 was pushed down by the principle of leverage of the cleat 45, and the inside and outside were sealed with the packing 42 and the compression bar 36.

Furthermore, as a countermeasure against water leakage, water entering between the combing ear 35 of the combing top 34 and the compression bar 36 due to the twisting of the hatch combing 32 or the hatch cover 33 due to dew or wind and rain due to temperature change in the hold. A drain pipe 46 for dropping the drain pipe is provided, and at the end of the drain pipe 46, a check type drain valve 47 is provided.

[0010]

[Problems to be solved by the invention]

 As described in the previous section, packing and a compression bar seal the inside and outside of the building from wind and rain, and a drain pipe and a drain valve are provided to prevent water leakage.Hatch combing by rolling or pitching the hull in rough weather. In addition, the hatch cover deformed elastically, causing water to enter between the combing ears and the compression bar from the gap caused by twisting, and the water slid into the hold due to the sway of the hull.

Although there is a measure to increase the height of the combing ears, there is a problem that the height of the combing ears is limited in consideration of the interference with the ceiling of the hatch cover and the accuracy of manufacturing and mounting.

The present invention has been made in view of such inadequate points of the conventional technology, and its purpose is to deal with stormy weather, and to use general wind and rain (about Beau fort 6). However, in bad weather, hatch combing and the hatch cover will infiltrate between the combing ears and the compression bar due to torsion due to elastic deformation. Instead, they are trying to drain from the drain pipe.

[0013]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is based on the idea that a combing top having a fixed width is welded to the upper outer periphery of the hatch coaming, leaving a predetermined height of the combing ear at the upper end of the hatch coaming. Is a rubber plate attached to the height of the hatch cover ceiling, pressed with a flat steel plate and screwed with screws, and a compression bar is provided on the combing top over the entire circumference. The packing is fitted to the packing gutter, and the packing is installed so as to contact the compression bar. A drain pipe is provided between the bars, and a drain pipe is provided at the end of the drain pipe. In which lube is provided.

[0014]

【Example】

 As shown in FIG. 1, the technique of the present invention is provided with several cargo hatches H on the upper deck 1 and a rectangular hatch combing 2 at the edge of the hatch H. On the upper part of 2, a hatch cover 3 divided into several pieces serves as a cover.

A combing top 4 having a fixed width is welded to an upper outer periphery of the hatch combing 2 while leaving a predetermined height of a combing ear 5 at an upper end of the hatch combing 2.

A rubber plate R made of synthetic rubber having a height up to the hatch cover ceiling 9 is adhered to the combing ears 5 at the feet, pressed with a flat steel plate P, and screwed with screws B.

Further, a compression bar (pressure bar) 6 is provided over the entire circumference of the combing top 4 at a predetermined position from the edge of the hatch combing 2.

Further, two rails 7 are laid on the combing top 4 in the ship side direction.

The hatch cover 3 forms a box with a cover top plate 8, a cover ceiling 9, and four cover side plates 10, and a packing gutter 11 is provided at a peripheral end of the cover ceiling 9. 11, a packing 12 made of synthetic rubber is fitted.

Further, a wheel mounting arm 13 is extended from both sides of the hatch cover 3 on the side of the ship, and two wheels 14 are pivotally mounted on the rails 7. The rider rides on the rails 7 to move the hatch cover 3 in the longitudinal direction of the hull. It has become.

When the hatch cover 3 moves to a predetermined location, the wheel 14 falls into the depression of the rail 7, and the packing 12 of the hatch cover 3 is installed so as to hit the compression bar 6. The hatch cover 3 is pushed down by the lever principle of the cleat 15, and the inside and the outside are sealed by the packing 12 and the compression bar 6.

Further, as a countermeasure against water leakage, a drain pipe 16 is provided between the combing ear 5 of the combing top 4 and the compression bar 6 to drain water entering from the exposure. A mold drain valve 17 is provided.

[0023]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. As a countermeasure in case of stormy weather, the combing ears were raised with rubber plates, and the hatch coaming and the hatch cover leaked from the combing ears and the compression bar due to torsion due to elastic deformation. Instead, it drains from the drain pipe and uses rubber made of synthetic rubber, so interference with the cover ceiling can be reduced and no damage is caused.
