Abstract

Disclosed are a screw unit and a lifting device utilizing the screw unit. The screw unit comprises internal threads and a jointing seat. The lifting device is provided with a rotation assembly which is meshed with the screw unit and can rotate relative to the screw unit and move to form a screw module. The lifting device comprises a lifting bearing support which is arranged on a rotation unit of the screw module in a crossing mode, a gear motor arranged on the lifting bearing support, and a plurality of transmission assemblies for connecting the gear motor and the rotation assembly, wherein the jointing seat is arranged on the screw unit of the screw module, and the internal threads are adopted, and accordingly when travel distances are increased by joining, and the screw unit is connected in series, structural strength is conveniently improved, supporting is conveniently strengthened, jointing can be conveniently conducted, and therefore safety is improved, and being broken and dropping is avoided.

Description

Technical field [0001] The invention relates to a screw unit and a lifting device using the screw unit, in particular to a screw unit and a lifting device used in elevators or mechanical parking equipment. Background technique [0002] Generally, elevators use driving parts to pull steel cables to make the elevator move up and down, and mechanical parking equipment uses driving parts to pull steel cables or chains to make parking equipment move up and down. The use of steel cables and chains has the risk of breaking, so it is safe Hidden dangers. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a screw unit and a lifting device using the screw unit, so as to improve the problem that the steel cable or chain used in the lifting device has the risk of breaking and the safety is not good. [0004] In order to achieve the above object, the present invention provides a screw unit including a body with a moving groove and forming...
