Abstract
The utility model discloses a hoist for a hydraulic gate, particularly a horizontal screw hoist. The horizontal screw hoist mainly consists of a power machine, a transmission speed-changing system, a guide screw, nuts, a base and a hand crank, and the guide screw is driven to rotate by a transmission element. The horizontal screw hoist is characterized in that the guide screw is arranged horizontally and is an integrated guide screw, i.e. the guide screw includes two guide screws with connected coaxial lines and opposite thread screwing directions; a polish lever is arranged between the two threaded parts of the integrated guide screw, and is provided with a transmission speed-changing component connected with the main transmission speed-changing system and located on the base; and the two nuts are provided with mechanical devices which are connected with the gate through matching mechanical facilities and connecting elements. The horizontal screw hoist solves the problem that the guide screw is too long, is convenient to manufacture, store, transport, install and maintain, prolongs the service life of equipment, increases the height where the gate is opened, and can be used on small and medium hydraulic gates which are not frequently opened or closed to replace an expensive winding hoist, so that the engineering investment can be saved greatly.
