Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a safety cover device for an open mouth, and more particularly, to an open mouth safety cover device installed at an opening formed in a deck or a building in a building of a construction site when a ship is dried.

Generally, the opening is composed of a manhole that can be accessed by a person from the road surface to an underground space where the underground facility is installed, or a passageway which is installed from the deck when the ship is dried and connected to the upper and lower floors.

In particular, a manhole cover is used in the manhole to prevent falling from the road surface, and a circular shape is mainly used. In addition, in order to ensure the safety of pedestrians and workers during the manhole operation, in case the manhole cover is open, a safety net is installed in order to prevent people from accidentally falling off or falling down in the manhole, It is prepared to prepare for an accident.

However, in the conventional safety net of the manhole, when the manhole cover is opened or installed in a fixed manner, the operator who enters and exits the manhole has many inconveniences to use, and the stability is uncertain.

Also, since the cover is hingedly protruded from the upper part of the manhole formed for the passenger or the worker to the deck of the ship, there is a problem that the passengers or the worker are prevented from moving when moving. In addition, since the lid protrudes upward, there is a problem that the cargo can not be loaded on the upper part.

In particular, the manhole cover or the manhole cover of the road surface or the ship deck is made of heavy steel material, which makes it difficult for the ship or the operator to move, and there is a danger of safety accident due to the heavy weight of the manhole cover or the manhole cover. There was also a problem that it was difficult to pass.
