Electric side-moving type hatch cover
The invention provides an electric side-moving type hatch cover. The electric side-moving type hatch cover comprises two cover plates and a driving device, wherein the cover plates are arranged on a hatch main body in a sliding manner. The driving device comprises a rack, a sector gear and a driving gear, wherein the rack is arranged on an inner side face of the cover plate towards the hatch main body, one end of the sector gear is fixed on the hatch main body in a rotating manner, a gear wheel is arranged at the other end of the sector gear and is arranged at one side of the rack, and the driving gear is fixed on the hatch main body and is arranged at the other side of the rack; when the cover plates are at a jacked-up state, the driving gear and the sector gear are in meshed transmission; when the cover plates transits from the jacked-up state to a translation state, the tail end of the sector gear is overlapped with a start end of the rack, and the driving gear is meshed with the rack instead of the sector gear; when the cover plates are at a translation state, the driving gear and the rack are in meshed transmission. According to the invention, as a driving device is provided, the hatch cover can be not only lifted but also moved laterally, and moreover the electric side-moving type hatch cover has the advantages of whole simple operation system, greatly saved ship space and reduced mounting workload.
