The present invention relates to a complex floodgate winch and, more specifically, to a complex floodgate winch comprising: a main body; a hydraulic device controlling the rotation direction of a hydraulic motor by increasing and decreasing oil pressure by installing in the main body; a driving unit located above the hydraulic device and driving the hydraulic deice by the rotation of the driving shaft; a main shaft gear installed in the main body to erect and rotated by the hydraulic motor of the hydraulic device; a main shaft fastened in the center of the main shaft gear and extending to both ends of the main shaft gear; and a winching means winching the floodgate on both end parts of the main shaft. As above, the complex floodgate winch of the present invention can perform smooth winching by winching a floodgate using the pressure of a fluid, can prevent the floodgate from falling or rapidly dropping by installing a reverse rotation preventing device, and can safely and efficiently control the floodgate by a dual control device. In particular, the present invention minimizes the driving motor from three phases into a single phase as compared to the prior driving motor, thereby reducing production costs and maintenance expenses, maximizing operation using oil pressure and the minimum force, performing construction efficient in space use by reducing the weigh and volume of appearance, and having compatibility with the products manufactured in the existing company, such as a pin-jack type, a screw type, a wire type, a hydraulic cylinder type. |
