Utility model content
The purpose of this utility model is: a kind of lifting tower based on twin-stage leading screw that providing can Fast Installation, dismantle, maintain easily.
The technical scheme that the utility model adopts is as follows:
A kind of lifting tower based on twin-stage leading screw, comprise pedestal, one-level leading screw, secondary leading screw, one-level push rod, secondary push rod, connecting rod and actuating device, pedestal bottom is provided with the base that actuating device is installed, described actuating device is connected with the one-level leading screw being rotatably connected on base by gear pair, in pedestal, be provided with the undersetting being connected with one-level leading screw, described undersetting is done upper and lower straight-line motion by being arranged on the key of both sides in pedestal, one-level feed screw nut is installed on undersetting, one-level feed screw nut passes through plastic bearing, sleeve is connected with connecting rod lower end, small end drives secondary leading screw to do upper and lower straight-line motion by secondary feed screw nut, secondary leading screw upper end is provided with the upper bracket of placing load, on described upper bracket, be fixedly connected with secondary push rod, secondary push rod limits its axial rotation by the key being arranged on one-level push rod, one-level push rod limits its axial rotation by the key being arranged on pedestal both sides.
Further, on described one-level push rod and secondary push rod, be equipped with threaded pin, when one-level push rod, secondary pushrod movement are to end position, one-level push rod is connected with pedestal by threaded pin, and secondary push rod is connected with one-level push rod by threaded pin.
Further, described one-level leading screw is hollow lead screw, and one-level leading screw end is provided with the boss being connected with gear pair.
Further, described secondary leading screw is ball-screw.
Further, described actuating device is speed reducing driving device.
The beneficial effects of the utility model are: the utility model is simple in structure, form volume little, have avoided the labyrinth of traditional lifting system to form (as hydraulic efficiency pressure system, steel rope, pulley etc.); Adopt electromechanical integrated structure, the leading screw in its structure has auto-lock function, even the in the situation that of power-off, also can keep the front state of power-off; Have processing, installation, maintenance conveniently, adaptive capacity to environment is good, low cost and other advantages.
