Abstract

The invention discloses a concentric wheel set cascading device which transcends a pulley block and can achieve heavy lifting. The concentric wheel set cascading device comprises a drive device, a speed reducer and a lifting device, wherein the speed reducer is in transmission connection between the drive device and the lifting device; the speed reducer comprises a rack, an concentric wheel set reducing mechanism and an output shaft; the concentric wheel set reducing mechanism comprises concentric wheels, a wheel axle and a chain; and the concentric wheel set is taken as the reducing mechanism for power transmission, so that the labor is saved, the occupied space is small and the concentric wheel set lifting device can be widely applied to production activities of human beings. The concentric wheel set reducing mechanism is a comprehensive machine integrating the characteristics of a lever, a fixed pulley, a movable pulley and the pulley block, has multiple connection forms and is suitable for lifting operations of different weight ranges; and meanwhile, the concentric wheel set reducing mechanism can be arranged on other objects (a vehicle, a ship and the like) which need to be driven; objects can be slowly moved by artificially using the concentric wheel set reducing mechanism in the absence of power drive.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a concentric wheel set lifting device. Background technique [0002] At present, most of the lifting devices are realized by pulley blocks, but it is technically difficult to realize the lifting of large heavy objects. Our country has recently developed a large-scale crane that can lift 200 tons, and this device can successfully achieve larger lifting. The device can also be used for all drives, such as automobiles, ships, elevators, etc. If there is no power, it can be driven by artificial power, but the running speed is relatively much slower. This device will replace the pulley block and become an important lifting device, and the pulley block will fade out of human activities. Contents of the invention [0003] The object of the present invention is to provide a concentric wheel group lifting device, which adopts a concentric wheel group deceleration mechanism, is...
