Abstract

The invention discloses a rotary cantilever lifting device. The rotary cantilever lifting device comprises a walking platform, a rotating disc, a stand column, a stand column base, a cantilever, a sliding table, a screw, a screw sliding block, a screw base, a screw motor, a reinforced inclined support and a lifting unit; the rotating disc is horizontally arranged on the walking platform, a drive device can drive the rotating disc to rotate along the axis, the stand column base is vertically arranged, the bottom of the stand column base and the axis of the upper bottom face of the rotating disc are fixedly connected, a reinforcing rib is arranged at the position, opposite to the face of the rotating disc, of the periphery of the stand column base, and the lower end of the stand column is fixedly arranged at the upper end of the stand column base. The device is simple and ingenious in structure, centrifugal force brake is sufficiently used, the brake whole process is purely mechanical, and the beneficial effects of being high in reliability

Description

technical field [0001] The invention belongs to the field of cranes, and in particular relates to a rotary cantilever lifting device and method. Background technique [0002] Rotary cantilever lifting equipment is mainly used for the loading and unloading of goods in outdoor cargo yards, stockyards, and bulk cargo; if the equipment fails during the process of lifting heavy objects, the heavy objects may drop rapidly, causing danger. SUMMARY OF THE INVENTION [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a rotary cantilever hoisting device and method, which can play a braking role in the process of overspeed descending of heavy objects. [0004] Technical solution: In order to achieve the above purpose, a rotary cantilever lifting device of the present invention includes a walking platform, a rotating disc, a column, a column seat, a cantilever, a sliding table, a screw, a screw slider, a screw seat,...
