Abstract

The invention relates to an A60-class fireproof watertight hatch cover which is characterized in that a base comprises an inner enclosing plate, an outer enclosing plate and an upper base plate, wherein the inner enclosing plate and the outer enclosing plate are respectively welded on the upper base plate; a first TC plate is added between the inner enclosing plate and the outer enclosing plate; after first ceramic cotton is filled, a lower sealing plate is welded; the enclosing plates are welded on a cover plate, and a fireproof layer baffle plate and a reinforcing plate are respectively welded on the cover plate; a second TC plate and second ceramic cotton are filled between the cover plate and a cover; a non-drive mechanism fixing seat is welded on the cover plate; an inclined wedge iswelded on the inner enclosing plate; and a spring hinge device is welded on the outer enclosing plate and the cover plate. The invention has the advantage of simple, compact and reasonable structure,can be quickly opened by a central hand wheel drive device and the spring hinge device, is fixed by adopting a bolt with a tongue safely and reliably after being opened, is quickly opened and closed and has the watertight test pressure of 0.25MPa.

Description

technical field [0001] The invention relates to an A60-level fast opening and closing fireproof watertight hatch cover, specifically for a deck with A-level division requirements, meeting the fireproof level of A60, and the tightness test pressure requirement of 0.25MPa, which belongs to the ship outfitting technology field. Background technique [0002] With the development of the ship industry, customers have higher and higher requirements for ship outfitting equipment. In the existing technology, the A60 fireproof watertight hatch cover is mainly composed of base, TC plate, clamping device, cover plate, ceramic cotton, Hinge device, wedge, buffer device, handle, lock device and other connections. This kind of A60 grade fireproof watertight hatch cover is opened or closed by several clamping devices on the cover plate, and then opened and closed by the hinge device and counterweight device on the cover and frame. The maximum watertight test pressure of this kind of A60 c...
