Abstract

The invention discloses a chain type multi-grade screw rod hoisting platform. The chain type multi-grade screw rod hoisting platform comprises a chain transmission part, screw rod groups and a platform, wherein the platform is arranged at the output end of one group or a plurality of groups of screw rod groups; the chain transmission part is matched and connected with the output ends of the screw rod groups and the output ends of the screw rod groups are driven to rotate, so that the platform is driven to move up and down; synchronous hoisting of a plurality of grades of screw rods is realized through chain type transmission, and a buffering measure can guarantee that an excessive spiral pair locking force is not generated after each grade of the screw rods is arranged in place, so that the system can be normally hoisted to work; and self locking can be realized at any position through a trapezoid thread pair. The chain type multi-grade screw rod hoisting platform can be applied to low-speed hoisting of various platforms, is compact in structure and has a wide application field and the like. Energy sources can be provided for a motor and hydraulic dividing is not used; and supporting equipment is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a chain-type multi-stage lead screw lifting platform. It can be widely used in electric vertical and vertical devices, electric lifting and extension, CNC machine tools, control execution systems, positioning systems, plastic machinery, military industry, high-load linear motion systems, measuring equipment, high-speed rotary motion, etc., to convert rotary motion into linear motion. Background technique [0002] At present, engineering lifting platforms are mainly fork-type lifting platforms and door-type lifting platforms. The common multi-stage screw structure is mostly used in erecting devices, and the phenomenon of unstable operation, failure, and jamming occurs during the torque transmission process. , it cannot be self-locked at any position, and it is not easy to maintain, which greatly reduces the efficiency of the screw to transmit torque, a...
