Problems solved by technology

According to prior art solutions, in order to raise and lower the loading hatches and on the other hand to drive them, several different devices are required in the equipment, which is not desirable because the equipment becomes more prone to failure and more complex, and Increased demand for services and therefore higher costs

Embodiment Construction

[0030] according to Figure 1a and Figure 1b , the operating mechanism 25 according to the invention is implemented by sliding the base 1 and the rotatable lever arms 2 and 3 . The sliding base 1 is supported to move on one or more guides 4 (left guide 4', right guide 4") fixed to the hull of the vessel. The lever arm 2 is hinged to is fixed to the sliding base by a hinge 14, and the lever arm 3 is fixed to the hull of a vessel in an articulated manner by a hinge 13, for example directly or otherwise. The lever arms 2, 3 are also articulated to each other by a hinge 15. Figure 1b As can be seen in , an actuator 5 such as an electric drive or a hydraulic drive rotates the gear 6 and further rotates the gear 11 since the gear 11 is in contact with the gear 6 . The shafts of the gears are designated with reference numerals 20 and 21 . During the lifting phase of the loading hatch, i.e. when it is desired to lift the hatch panel 19 upwards, the gear 6 is in this case connected...

Abstract

Operating mechanism (25) of a loading hatch of a cargo ship, which loading hatch comprises at least one hatch panel (18,19), which hatch panel can be moved between an open position and a closed position for opening and closing the cargo space (23) of a cargo ship, and in which at least one actuator apparatus is fitted to the hatch panel, or in connection with it, for achieving movement of the hatch panel between the open position and the closed position, and in which the hatch panel can be raised into a travel position and can be lowered into a locking position, a sliding base (1), which is arranged to slide supported by a guide or guides (4 ',4'') on the hull of the ship, and by means of the aforementioned sliding base as well as at least one hinged lever arm (2,3) or sector gear connected directly or indirectly to the hull of the ship.

Description

technical field [0001] The present invention relates to operating mechanisms for loading hatches of ships, and more particularly to operating mechanisms for loading hatches of cargo ships. Cargo ships typically include one or more cargo hatches formed by one or more hatch panels that must be moved to cover or open the vessel's cargo holds (ie cargo spaces). With the loading hatch operating mechanism according to the invention, the aforementioned hatch panel can be moved between its open position and its closed position, so that the cargo compartment of the ship can be opened or closed. [0002] This is especially true when closing the hatch because the seal between the cargo hatch panels has to be compressed, while on the other hand a lot of force is required since the cargo hatch panel has to be lifted upwards into the travel position when opening the hatch. [0003] Therefore, the present invention relates to the opening and closing of cargo hatches of cargo ships by means ...
