Abstract

A metal-to-metal gap adjuster of a hatch is disclosed. In the metal-to-metal gap adjusting device of the hatch according to the embodiment of the present invention, the gap between the hatch cover and the hatch main body can be arbitrarily adjusted by using the coupling structure of the bolts, and thus, the manufacturing and installation of the hatch From the ship's post-delivery stage, it is possible to comply with the NO GAP requirement, which is required by the International Federation of Classification Societies (IACS), and a certain gap with the hatch tightly locked. Breaking away from the existing method of adjusting the gap to maintain the gap, install the gap adjusting device at a certain height first, and then adjust the no gap by using bolts and nuts, and the productivity is greatly improved. By suggesting a CONTACT PIECE with a simple structure using bolts widely used, it is possible to easily adjust the height at any time, so it is always tight. It can maintain the state, and the main parts such as bolts, nuts, washers, etc. are made of materials that can be easily obtained anywhere, which reduces the manufacturing cost and facilitates replacement in case of breakage.

Description

Hatch Metal-to-Metal Gap Adjuster {ADJUSTABLE PIECE FOR METAL-TO-METAL CONTACT}

The present invention relates to a hatch installed on a deck for loading and unloading cargo or entering a person in a ship, and more particularly, metal of the hatch to prevent excessive crimping of the gasket installed between the hatch main body and the hatch cover. It relates to a two-metal gap adjusting device.

Typically, hatches are placed on deck for loading and unloading cargo or for human entry and exit. Hatches installed on ships must comply with a number of rules, in particular those required by the International Federation of Classification Societies (IACS). IACS URS26 sets the rules for strength and safety for small hatches on the bow side. Among the regulations, there is a requirement for safety-related metal to metal contact (METAL-TO-METAL CONTACT), which is loose when the gasket is subjected to excessive OVER COMPRESSION by external forces such as waves. This is to prevent it because it can be lost or displaced.

1 is a plan view showing a hatch structure according to the prior art.

Referring to FIG. 1, a hatch 10 of the prior art is disclosed. The hatch 10 is formed in a rectangular frame when viewed in a plane, is installed to open or close the hatch cover 13 in the upper portion of the hatch body 11, it is possible to rotate in any one of the four sides By installing the hinge device, the hatch cover 13 is rotated about the hinge device to open or close the hinge device.

Locking device 20 is installed around each of the four sides of the hatch 10 to be fixedly coupled between the hatch body 11 and the hatch cover 13, the locking device 20 is attached to the hatch body 11 Hinge bracket 21 is hinged. In this case, the hinge bracket 21 is formed at a position where the shaft hole through which the hinge shaft 22 is coupled to face is formed, and one end of the pivot bolt 23 is hinged on the hinge bracket 21 using the hinge shaft 22. Is coupled to the shaft, the butterfly nut 25 is spirally coupled to the free end side of the rotating bolt 23, the rotating bolt 23 is rotated about the hinge shaft 22 to the top surface of the hatch cover (13) Guide coupled to the guide groove of the fork plate 27 is coupled to, and then, by rotating the butterfly nut 25 coupled to the rotating bolt 23 is fixed by pressing the fork plate 27.

FIG. 2 is a cross-sectional view taken along the line A-A of FIG. 1, and FIG. 3 is an enlarged view of portion “A” of FIG.

2 and 3, a gasket 30 is installed between the hatch body 11 and the hatch cover 13.

At this time, a gap bar 40 is installed to prevent excessive compression of the gasket 30 installed between the hatch main body 11 and the hatch cover 13.

The gap bar 40 is installed above the hinge bracket 21 of the locking device 20, and is installed at a position facing the edge of the hatch cover 13.

At present, the gap between the gap bar 40 and the edge of the hatch cover 13 maintains a gap of about 3 to 4 mm in consideration of the temperature difference and the wear of the gasket due to the seasonal change. However, this also has a problem that the design criteria are frequently changed due to different criteria for the gap (GAP) for each class, and different criteria for owners.

In addition, in the related art, since the hatch cover 13 is completely locked by the locking device 20 and the gap bar 40 must be installed in accordance with a predetermined gap in a tightly tightened state, the size of the gap bar 40 is increased. There was a problem that the pre-production is difficult to know in advance.

In addition, even after the installation of the gap bar 40, the hatch cover 13 may not be locked tightly. In this case, there is a problem in that the gap bar 40 needs to be manufactured again.

The present invention has been made to solve the problems of the prior art, the object of the present invention is a metal-to-metal gap adjusting device of the hatch to prevent excessive compression of the gasket installed between the hatch body and the hatch cover, the coupling of the bolt It is to provide a metal-to-metal gap adjusting device of the hatch so that the gap with the hatch cover can be arbitrarily adjusted using the structure.
