Problems solved by technology

[0007] Among them, the prior art has been hampered by the need for a separate device to raise / lower the decks, but also to drive them
Furthermore, this additional step of locking the covers may be overlooked by the ship's personnel, and the covers may be accidentally opened at sea, resulting in damage to the cargo, or even complete cargo damage due to the deterioration of the cover's weatherproof performance
In the worst case, the opening of the cover could endanger the safety of the entire freighter

Embodiment Construction

[0023] Referring to Figures 1A and 1B, there is shown a freighter hatch 1 in its closed position, provided with an actuator mechanism according to the invention. The hatch cover 1 includes two cover plates 1', 1". The main shape of the toothed rack 2 mounted on the cover plates is straight, and only the end is curved. The drive mechanism also includes a toothed roller mounted on it. 5 of the support frame 4 and a support element 6 that works in contact with the pinion rack. The support element 6 may be any functionally appropriate sliding element or rotating member, such as an idler wheel (as shown in the figure, thus, hereinafter referred to as This element is called an idler). In turn, the frame 4 is connected to the hull by a pivot pin 7. In this exemplary embodiment, the toothed rack 2 is substantially in front of the cover plates 1', 1 " The midpoint of the rear edge, although the curved portion of the rack is outside the front edge of the rack. In this context, the term...

Abstract

An actuator mechanism of a cargo ship hatch is disclosed, the hatch comprising at least one hatch panel (1',1'') movable between its open / closed positions, the hatch panel having connected thereto and aligned in a direction substantially parallel to the hatch panel movement a toothed rack (2) actuated by a toothed wheel (5) driven by an actuator means. The invention is implemented by way of providing at a least a portion of the toothed rack (2) with a curved shape and having mounted at a distance from the toothed wheel (5), substantially close to the toothed wheel, a backing element (6) adapted to keep the toothed rack (2) meshed with the toothed wheel (5).

Description

technical field [0001] The present invention relates to an actuator mechanism for a hatch cover of a freighter comprising at least one cover plate movable between its open / closed positions, the cover plate having a Aligned rack and pinion driven by a pinned roller driven by a drive unit. [0002] Thus, the present invention relates in particular to the opening / closing of freighter decks with actuator means. Particularly high forces are required when closing the flaps when it is necessary to press the seal between the flaps, and when opening the flaps when it is necessary to lift the flaps into their drive position. Background technique [0003] Traditionally, hatch drive mechanisms use separate drives to raise / lower the cover and, on the other hand, to actually drive the cover. [0004] For example, it is possible to connect a pair of cylinder drive rod mechanisms between each pair of adjacent cover plates, or use a roller jacking mechanism with eight rollers for each pair...
