Repulsion type magnetic-suspension rotating door device

Abstract

A device that uses repulsive magnetic suspension to support a revolving door. Its structure is: a permanent magnet with opposite magnetic properties is placed between the hanger and the fixed frame, and the principle of permanent magnets repelling each other with the same sex and attracting each other with the opposite sex is used to make the hanger and the door The body is suspended, and a permanent magnet is placed on the outer ring of the ceiling, and a permanent magnet with opposite magnetic poles is also placed at the corresponding position of the fixed frame to prevent the door body from tilting. Because the whole door body is suspended, there is no frictional force, and the door body can be pushed with very little force, thus eliminating the power source, thrust bearing and its corresponding transmission system and control system. The revolving door supported by the device has the characteristics of no noise, no friction, energy saving, no loss, low cost and the like. It can be widely used in the field of automatic revolving doors of various high-end hotels, restaurants, restaurants, office buildings, etc.

Description

technical field [0001] The device belongs to the automatic revolving door for buildings. Background technique: [0002] Automatic revolving doors are widely used in various high-end restaurants, hotels, and office buildings, but automatic revolving doors generally use thrust bearings to support the door body. Since the door body of the revolving door is very heavy, the general thrust bearing service time More than half a year will produce a lot of noise, which will greatly affect the use effect of the revolving door and increase maintenance costs. In addition, since the door body is very heavy, using a motor to drive the revolving door will consume energy continuously and increase the use cost. Invention content: [0003] The purpose of the device is to provide a revolving door support device with simple structure, flexible rotation, no noise and energy saving. [0004] In order to achieve the above object, the device is realized by adopting the following scheme. The de...
