Stopping device driven by hydraulic cylinder to ascend and descend

Abstract

The invention discloses a stopping device driven by a hydraulic cylinder to ascend and descend. The stopping device comprises a bottom assembly, a walking connection frame assembly, a walking mechanism assembly, a supporting frame, a rotating oil cylinder, an upper bearing connection frame, a lifting mechanism and a car carrying plate assembly. The lifting mechanism comprises a lifting inner rail assembly, a lifting middle rail assembly, a lifting outer rail assembly, a lifting oil cylinder, a first lifting chain, a second lifting chain and a third lifting chain. The oil cylinder is adopted in the lifting mechanism for ascending, the assemblies descend when oil flows out of a lower cavity of the oil cylinder, transmission is easy and convenient, the extending and retracting speed of the hydraulic cylinder can be adjusted by controlling the flow of a hydraulic pump through an electrical system, stepless speed regulation and a large speed regulation range can be achieved, a speed reducer needed in an ordinary motor transmission mode to carry out intermediate transmission is omitted, oil cylinder driving is rapid in reaction, sensitivity and reliability are high, and the service life is long. The device slowly descends when a lower oil pipe bursts suddenly so as to be prevented from falling suddenly, and the accident occurrence rate is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile parking facilities, in particular to a parking device driven and lifted by a hydraulic oil cylinder. 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 gar...

Problems solved by technology

The current lifting device is driven by a motor, usually through a motor and a reducer. In some unexpected situations such as a power failure, the rapid decline of the vehicle-carrying plate may easily lead to accidents.
