Abstract

The present invention proposes a hatch cover device capable of opening and closing the hatch cover with a simple structure using only an electric actuator. In the hatch cover device of the present invention, the lift and movement of the cover plate when the hatch cover is opened and closed, which are driven by individual drive sources (actuators) in the prior art, are all driven by a common actuator. Accordingly, the hatch cover can be opened and closed with fewer actuators, and the simplification and cost reduction of the device can be realized. In particular, since an electric actuator is used as the actuator, there is no need to install a hydraulic actuator and hydraulic piping for its operation on the deck, which not only enables simplification and cost reduction of the device, but also Prevent marine pollution caused by oil.

Description

(1) Technical field [0001] The present invention relates to a hatch cover device installed on the hold of a cargo ship. (2) Background technology [0002] As the prior art examples of such a hatch cover device, for example, there are technologies disclosed in Patent Documents 1 to 5, figure 1 and figure 2 An example of a cargo ship described in these documents is schematically shown, figure 1 (a) is a sectional view of the side of the hull, figure 1 (b) is a view of the hull viewed from above, figure 2 It is a perspective view which shows the structure of a hatch cover apparatus. The cargo ship 1 shown in the figure is in the form of having a plurality of cabins on the hull 2. In the figure, there are four cabins 3A-3D, and hatches for closing the hatches 5A-5D corresponding to these cabins are provided on the deck 4. Cover devices 6A to 6D. Such as figure 1 As shown in (b), each hatch cover device has two cover plates 7a, 7b respectively, and the two sides of each ...
