Hoisting device in three-section hoisting pattern

Abstract

The invention discloses a hoisting device in a three-section hoisting pattern. The hoisting device comprises a hoisting inner rail assembly, a hoisting middle rail assembly, a hoisting outer rail assembly, a hoisting oil cylinder, a first hoisting chain, a second hoisting chain and a third hoisting chain, wherein both ends of the hoisting inner rail assembly, the hoisting middle rail assembly and the hoisting outer rail assembly are all in square-groove shape; the hoisting middle rail assembly moves up and down in the square groove of the hoisting inner rail assembly by use of a composite roller and the hoisting outer rail assembly moves up and down in the square groove of the hoisting middle rail assembly by use of a composite roller. The hoisting device in the three-section hoisting pattern has the advantages that the three-section hoisting pattern mechanism is adopted and three groups of associated guide rails work cooperatively, and therefore, the top space is saved, the transmission ratio of a chain wheel-chain transmission mechanism is accurate so that the rise-and-fall speeds of motion at different hoisting points are kept consistent, smooth and steady rise and fall and stress balance of a vehicle carrying plate are realized, the synchronism of rising of the vehicle carrying plate is good, and the synchronization mechanism is simple in structure, convenient to operate and control, high in reliability and low in requirement on the interior mounting space.

Description

Technical field [0001] The invention relates to the technical field of automobile parking facilities, in particular to a three-section hoisting style hoisting device. Background technique [0002] With population growth and social development, vehicles are increasing day by day. Due to the rapid increase in the number of cars, the problem of difficult parking has become increasingly prominent. Especially large vehicles, such as large passenger cars, are mostly parked in open-air parking lots, occupying a lot of plane space. Especially in the prosperous areas of big cities, the plane parking lot has been unable to meet the needs of large vehicles parking and in and out. In the prosperous areas of big cities where there is a lot of money, the use of car parking garages and underground parking garages is an inevitable trend for future development. However, the number of underground parking garages is limited, and the construction of the underground structure is difficult. Therefo...
