A lifting device with a three-section lifting style

Abstract

The invention discloses a lifting device with a three-section lifting style, which comprises a lifting inner rail assembly, a lifting middle rail assembly, a lifting outer rail assembly, a lifting oil cylinder, a lifting chain 1, a lifting chain 2 and a lifting Chain 3, the two ends of the lifting inner rail assembly, the lifting middle rail assembly and the lifting outer rail assembly are all in the shape of square grooves, and the lifting middle rail assembly goes up and down in the square groove of the lifting inner rail assembly through composite rollers Moving, the lifting outer rail assembly moves up and down in the square groove of the lifting middle rail assembly through composite rollers. The invention adopts a three-section lifting mechanism, and three sets of associated guide rails work together to save upper space. The transmission ratio of the sprocket chain transmission mechanism is accurate, so that the lifting speed of different lifting points is strictly consistent, and the stability of the vehicle-carrying plate is realized. The lifting and force are balanced, the rising synchronization is good, the structure of the synchronization mechanism is simple, the operation and control are convenient, the reliability is high, and the space requirement for indoor installation is low.

Description

technical field

[0001] The invention relates to the technical field of automobile parking facilities, in particular to a three-section lifting device. Background technique

[0002] With the growth of population and the development of society, vehicles are increasing day by day. Due to the rapid increase in the number of cars, the problem of parking difficulties has become increasingly prominent. Especially large vehicles, such as large passenger cars, are mostly parked in open-air parking lots, occupying a large amount of flat space. Especially in the bustling areas of big cities, flat parking lots can no longer meet the needs of large vehicles for parking and entering and exiting. In the bustling areas of big cities where every inch of land is very expensive, the use of three-dimensional parking garages and underground parking garages for cars will be an inevitable trend of future development. However, the number of underground parking garages is limited, and the constru...
