Problems solved by technology

[0002] At present, the existing elevators use the hoist as the driving force for the elevator to go up and down. Since the wire rope of the hoist will be worn or aged, the inertial impact force of the elevator operation is relatively large, which makes the elevator have potential safety hazards during use.

Abstract

The invention discloses a magnetic fluid elevator, comprising an elevator car. The magnetic fluid elevator is provided with a magnetic fluid lifting device which is connected with the elevator car; the magnetic fluid lifting device consists of a magnetic fluid container, a floating body, an electromagnetic coil, a braking device and a controller; the apparent density of a magnetic fluid is controlled by controlling magnetic flux of the electromagnetic coil by using the controller, so that the change of the buoyancy force of the floating body in the magnetic fluid is controlled, the lifting of the floating body is controlled by controlling the change of the buoyancy force, and the elevator car is driven to stably lift by using the floating body; when the buoyancy force is controlled to be equal to or close to the gravity, the stable stopping of the elevator is implemented, the inertial impact force of operation and braking is reduced and the safe braking of the elevator is carried out by using the braking device.

Description

technical field [0001] The invention relates to an elevator, in particular to a magnetic fluid elevator. Background technique [0002] At present, the existing elevators use the hoist as the driving force for the elevator to go up and down. Since the wire rope of the hoist will be worn or aged, the inertial impact force of the elevator operation is relatively large, which makes the elevator have potential safety hazards during use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a magnetic fluid elevator, which uses the change in the apparent density of the magnetic fluid to control the change in the buoyancy of the floating body in the magnetic fluid, and uses the change in buoyancy to control the lifting of the floating body. Elevator lifts provide people with a brand-new safety elevator with less inertial impact force. [0004] The technical scheme adopted in the present invention is: ...
