Description
Technical field
Elevator control gear field is the utility model is related to, specially a kind of energy-saving device of elevator.
Background technology
Elevator is a kind of vertical conveyor using motor as power, equipped with box-like gondola, for tier building multiply people or
Carrying goods.Also there is step, step plate is continuously run on crawler belt, is commonly called as escalator or moving sidewalk.Serve
Provide the fixed type lifting equipment of floor.Vertical lift elevator has a car, operate at least two row it is vertical or tilt
Between rigid guideway of the angle less than 15 °.Car size is easy to passenger's discrepancy or handling goods with structure type.Though traditionally its
How is type of drive, the general name using elevator as vertical transportation means of transport in building.By speed can divide slower elevators (1 meter/
It is second following), express lift (1~2 meter per second) and express elevator (more than 2 meter per seconds).19th century, mid-term started hydraulic elevator occur,
So far still applied on low-rise building.1852, the E.G. Otis in the U.S. developed the safety cage of rope hoisting.
The eighties, drive device have further improvement, and such as motor drives winding reel, using balance weight by worm-drive.19
In the end of the century, frictional wheel drive is employed, greatly increase the hoisting depth of elevator.
20 end of the century elevators are using permanent magnetic synchronous traction machine as power.Computer room occupation of land is greatly reduced, and there is energy
Consume low, efficient energy-saving, the advantages that lifting speed is fast, greatly boosting real estate develops to Super High direction.
Thyssen Krupp elevator company develops new " multiple elevator " can horizontal vertical operating.
But current elevator is without energy saver.
