Description

Description: TECHNICAL FIELD The present invention relates to an all-weather cargo handling facility for unloading cargo between a building installed on a quay and a cargo ship stopped on the quay.

[Prior Art] There is a case where a building capable of accommodating and storing luggage is installed on a quay where a cargo ship can stop, and cargo is unloaded between the building and the cargo ship.

In such a case, a crane is usually installed on the quay and the cargo is loaded and unloaded. However, in the case of rain, there is a problem that the load gets wet, and it is not suitable when handling loads such as steel plate coils that are not soaked in water.

For this reason, cargo handling equipment has been proposed in which the roof of the building is integrally extended to the sea where the cargo ship is stopped.

[Problems to be Solved by the Invention] However, in such a cargo handling facility, since the roof is always extended to the sea, it should be adopted as an obstacle to navigation when the sea side is the route of a ship. I can't.

Therefore, an object of the present invention is to solve the above problems and provide an all-weather cargo handling device that can prevent cargo from getting wet by covering the cargo handling place only in the case of rain and does not hinder the navigation of a ship when not working. Especially.

[Means for Solving the Problems] The present invention is directed to a building installed on a quay, which has a ceiling crane and two booms connected in parallel so that two parallel traveling paths of the overhead crane can be extended to the sea side. And a trolley that is hung between the traveling path and the boom in an overhanging state and is movably supported from the building to the tip of the boom, and is stored above the building so that it can be moved to the sea side via the trolley. ,
A movable roof that covers the upper side of the cargo ship stopped on the quay, a front cover that is provided on the bogie and that opens and closes the front under the moving roof, and a side cover that openably and closably covers both side surfaces under the moving roof. Be prepared.

[Operation] When carrying out cargo loading work in fine weather, the boom is extended and extended to the sea side, and the carriage is moved to the boom tip.
Further, the front cover and the front cover are left open.

In this state, the overhead crane may be moved along the traveling path and the boom to unload the cargo between the building and the freighter stopped at the quay.

When carrying out cargo handling work in rainy weather, when moving the bogie to the boom tip, move the moving roof from the building along the boom so that the moving roof covers the cargo ship above the sea from the building. It will be in a continuous state. In addition, the front cover and the side cover are closed to prevent rain from blowing into the surroundings under the moving roof.

Since the cargo handling work is performed by the overhead crane in a state where the cargo handling place is covered with the movable roof, the front cover, and the side cover in this way, it is possible to completely prevent the cargo from getting wet.

When the cargo handling work is not performed, the boom and moving roof are stored in the building so that they do not interfere with the navigation of the ship, and the bogie is located at the sea-side end of the traveling path to close the front cover. By doing so, it will function as the front wall of the building.
