Abstract

The invention discloses a lift platform with rate-based withdrawing of tail ends of chains by adopting a multiplying wheel. The lift platform comprises a holding plate, two first chains, two second chains, a transmission shaft, two transmission assemblies, a power device and a support table. One transmission assembly is arranged on each side of the holding plate and comprises a beam body, a driving assembly, a chain tail end fixing pin shaft, a multiplying sliding assembly and a chain hanging assembly. One ends of the first chains are fixed to the support table, and the other ends of the first chains extend into the beam bodies from left and sequentially wind around the driving assemblies and the multiplying sliding assemblies to be fixed to the chain tail end fixing pin shafts. One ends of the second chains are fixed to the support table, and the other ends of the second chains extend into the beam bodies from right and sequentially wind around the chain hanging assemblies, the driving assemblies and the multiplying sliding assemblies to be fixed to the chain tail end fixing pin shafts. The lift range of the lift platform can be expanded by times. According to the invention, the structure is compact, lifting is stable, automatic operation is achieved and the cost is low.

Description

technical field

[0001] The invention belongs to an elevating platform, in particular to an elevating platform with a retractable ratio at the end of a double wheel chain. Background technique

[0002] Lifting platform is a kind of hoisting machinery that transports people or objects vertically. It is used in factories, automatic warehouses, docks, logistics centers, and other logistics systems for vertical conveying equipment. It can also be used in high-level installation and maintenance operations: such as municipal maintenance, building decoration, etc., and can also be used in mechanical The lifting platform field of the three-dimensional parking garage. According to the lifting structure, the lifting platform can be divided into: scissor lifting platform, guide rail lifting platform, crank arm lifting platform and chain lifting platform, among which the cost of scissor lifting platform and crank arm lifting platform is low, but the height Limited, can only carry small...
