Problems solved by technology

Since this kind of hatch cover is located on the deck at the top of the cable cabin, it has only one fire-proof and weather-tight performance. Once the fire-proof rubber strips age, it will lose the fire-proof and weather-tight performance, making the fire-proof and weather-tight performance of this hatch cover poor.
And because this hatch cover is made of flat plate and the stiffener that is welded on the inner surface of the flat plate, when retracting the cable, the cable is directly in contact with the edge of the hatch, so that there is friction between the cable and the edge of the hatch, and the cable and the hatch are easily damaged. Abrasion, which in particular reduces the service life of the rope

Embodiment Construction

[0012] like figure 1 As shown, the fireproof cable hatch cover of the present invention includes a hatch 11 and a hatch cover 2 . A cylindrical coaming 10 whose length is adapted to the thickness of the bulkhead is installed in the hatch 11 , and the hatch cover 2 is arranged at both ends of the cylindrical coaming 10 . The lower sides of the two hatches 2 are respectively hinged to the lower sides of the two ends of the tubular coaming 10 by means of hinges 1 , so that the hatches 2 can be turned outward around the hinges 1 . There is a locking mechanism between the upper edge of the hatch cover 2 and the upper edge of the corresponding end of the cylindrical coaming plate 10 .

[0013] Described locking mechanism contains a locking platelet 4, and the plate face of locking platelet 4 is parallel with the outer surface of hatch cover 2, and one end of locking platelet 4 is welded on the outer surface edge of hatch cover 2, locks The other end of small plate 4 is processed w...

Abstract

The invention relates to a fire-resistant cable hatch deck. The fire-resistant cable hatch deck comprises a hatch and hatch covers. The fire-resistant cable hatch deck is characterized in that a cylinder-shaped coaming is arranged in the hatch, and the hatch covers are positioned at two ends of the cylinder-shaped coaming. The lower edges of the two hatch covers are correspondingly hinged to the lower edges of the two ends of the cylinder-shaped coaming through hinges so that the hatch covers can rotate outward around the hinges. A locking mechanism is arranged between the upper edges of the hatch covers and the upper edge of the corresponding end of the cylinder-shaped coaming. The fire-resistant cable hatch deck has good performance of fire prevention and weather tightness. According tothe fire-resistant cable hatch deck, the abrasion between the cable and the hatch is avoided, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to a hatch cover. Specifically, it is a fireproof cable hatch cover arranged on the bulkhead of the cabin to facilitate the passage of cables. Background technique [0002] At present, cabins for placing cables are mostly provided under the decks of ships, and the deck corresponding to the cabins is provided with hatches and hatches that are convenient for storage and retraction of cables. The hatch cover is only composed of a flat plate and a reinforcing rib welded on the inner side of the plate. One side of the hatch cover and the hatch is hinged together, and a locking mechanism is provided between the hatch cover and the other side of the hatch. With the help of fireproof rubber strips around the four sides, when the side hatch cover is closed, the two are in a sealed fit, so that this hatch cover has fireproof and weathertight performance. Since this kind of hatch cover is located on the deck at the top of the cable cabin, ...
