A ship hull manhole typhoon-resistant tooling device

Abstract

The invention aims at providing a ship hull manhole typhoon-resistant tooling device with simple structure, strong safety and convenient installation. The tooling device comprises a locking device, amanhole through which a person can enter the cabin and a manhole typhoon resistant tooling. The locking device comprises an annular vacuum concave sheet metal arranged on the periphery of the manhole,and the side wall of the annular vacuum concave sheet metal is provided with a first through hole. The first through hole is provided with a vacuum cover plate adapted to the first through hole, theaxis of the first through hole and the geometric center of the vacuum cover plate are positioned on the same straight line, a plurality of external bolts are arranged on the upper surface of the vacuum concave sheet metal, and the external bolts are adapted to the manhole typhoon-resistant tooling. The tooling device is applied to the technical field of manhole safety protection.

Description

technical field [0001] The invention relates to the technical field of manhole safety protection, in particular to an anti-typhoon tooling device for a hull manhole. Background technique [0002] At present, most of the outfitting and closing of hull sections are carried out in the open air. In coastal areas, typhoon and stormy weather conditions often occur. During construction of sections in rainy days, due to rainwater flowing into the cabin through manholes, the assembly and welding work is delayed. A large amount of clean water work is also added. At night, people fall at the manhole due to insufficient lighting or slippery rainy days. In order to ensure the safety of construction workers, railings and ordinary rain cloths are basically set up around the manholes of existing ships. Under the influence of typhoon wind, ordinary guardrails can't resist, so rainwater seeps into the manhole, which affects the assembly and welding work. Contents of the invention [0003] ...
