The invention discloses a headstock gear for a hydraulic gate, in particular a horizontal screw type headstock gear mainly comprising a power machine, a driving speed change system, a screw rod, two nuts, a machine seat and a hand crank, wherein the screw rod is driven to rotate by a driving part. The horizontal screw type headstock gear is characterized in that the screw rod is horizontally arranged and is a siamesed screw rod including two screw rods which are coaxially connected and have opposite thread rotating directions; a feeding rod is arranged between two threads of the siamesed screw rod and is provided with a driving speed change part which is connected with the main driving speed change system and is positioned on the machine seat; and mechanical devices are arranged on the two nuts and are connected with the gate by a mechanical facility and a connecting piece which are matched with the mechanical devices. The horizontal screw type headstock gear solves the problem that the screw rods are overlong, is convenient for manufacture, storage, transportation, installation and maintenance, prolongs the running service of the equipment, improves the door-opening height, can completely replace the winch hoist with expensive price on medium and small hydraulic gates in the infrequent start and close processes and can greatly save the engineering investment.
