Abstract

The present invention relates to a device adopting repulsion type magnetic suspension to support a rotating door. The device has the structure that permanent magnets with opposite magnetism are placed between a hanger frame and a fixing frame, and the hanger frame and a door body can be suspended by utilizing the theory of like-polarity repelling and unlike-polarity attracting of the permanent magnets. One permanent magnet is placed at the external circle of a ceiling board, and another permanent magnet with an opposite magnetic pole is placed at the position of the fixing frame corresponding to the permanent magnet for preventing the door body from tilting. Because the whole door body is suspended, no friction exists, and the door body can be pushed with tiny force; thus, a power source, a thrust bearing, a corresponding driving system and a control system are omitted. A rotating door supported by the device has the characteristics of no noise, no friction, energy saving, no loss, low cost, etc. The device can be widely used in the field of automatic rotating doors for various high-grade hotels, restaurants, public houses, office buildings, etc.

Description

Repulsion formula magnetic suspension revolving door device

Technical field

This device belongs to the automatic revolving door that building is used.

Background technology:

Automatic revolving door is widely used in various high-grade restaurants, hotel, the office building, but the employing that automatic revolving door is at present general all is that thrust bearing supports the door body, because the door body of revolving door is very heavy, so general thrust bearing surpasses and will produce bigger noise half a year service time, very influence the result of use of revolving door, increase maintenance cost.In addition,, use the driven by motor revolving door to rotate, increase use cost continuous consumes energy because the door body is very heavy.

Summary of the invention:

The purpose of this device be to provide a kind of simple in structure, rotate flexibly, the revolving door supporting arrangement of noiselessness, energy conservation.

For achieving the above object, this device is to adopt following proposal to realize.This device comprises suspension bracket, fixed mount, ceiling, bearing post, door body, curved wall, permanent magnet.The fixing upper support post in both sides, doorway that needs are installed revolving door, the inboard fixing revolving door curved wall of going up of bearing post, circular fixed disk is being supported in the bearing post top, it around the fixed disk edge that protrudes downwards, edge installed inside one circle permanent magnet, the fixed disk center is a circle hole, and a circle permanent magnet is also installed at periphery top, circle hole; Top, fixed disk circle hole is placed and is gone up circular hanging scaffold, circular hanging scaffold is a projective table type, and boss is upside down little and firmly be connected with the ceiling of revolving door, and a circle permanent magnet is installed on the anchor ring in the major part of boss, and corresponding with the permanent magnet at periphery top, fixed disk circle hole, and magnetic pole repels each other; In addition, all sides of the ceiling of revolving door also have a circle permanent magnet and corresponding with the permanent magnet of inboard, fixed disk edge, and magnetic pole repels each other the firm upward revolving door that connects of below.The principle of utilizing the permanent magnet same sex to repel each other like this is so the repulsion that the permanent magnet on the anchor ring produces in the permanent magnet of fixed disk circle hole periphery and the hanging scaffold major part makes the stable suspension of a body.When door body banking the time, because the fixed disk side of ceiling and incline direction is apart from minimizing, so the repulsion that the two corresponding permanent magnet produces sharply rises, because the distance of the fixed disk side of ceiling and incline direction increases, so the repulsion that the two corresponding permanent magnet produces sharply descends, like this, the making a concerted effort of generation make the revolving door body, thereby prevent that the body from tilting away from incline direction.So the repulsion that the permanent magnet of all sides of the permanent magnet of inboard, fixed disk edge and ceiling produces prevents that the body from tilting, thereby guarantee a door body stable suspersion.

The good effect of this device is, because rotary part did not directly contact after revolving door adopted magnetic levitation system, not friction, increase the life-span of product, reduced maintenance cost, do not had noise, and owing to make when promoting firmly very little, so can remove motor and corresponding transmission system and control system fully, make simple in structurely, can be widely used in high-grade hotel and office building.

The specific embodiment

With reference to the accompanying drawings 1, shown in Figure 2, in fixing revolving door curved wall 6, be revolving door body 5, curved wall 6 both sides are the bearing post of fixing 4; Bearing post 4 upper supports circular fixed disk 2, and revolving door ceiling 3 and revolving door body 5 and circular hanging scaffold 1 firmly link together.With reference to the accompanying drawings 5 and accompanying drawing 6 shown in, hanging scaffold 1 is a projective table type, one all permanent magnets 7 are installed on the interior anchor ring of major part, with reference to the accompanying drawings 9 and accompanying drawing 10 shown in, the top of circular fixed disk 2 has its edge end face of a center circle hole that one all permanent magnets 8 are arranged, and is such as shown in Figure 3,

permanent magnet

7,8 positions are corresponding, and magnetic pole repels each other, and the relative area of permanent magnet is enough big, guarantees to produce enough repulsion and by circular hanging scaffold 1 revolving door body 5 is suspended.Shown in accompanying drawing 9 and accompanying drawing 10, the edge that circular fixed disk 3 is given prominence to downwards around being, the inboard week symmetry placement of projecting edge permanent magnet 9, as accompanying drawing 7 and shown in Figure 8, the neighboring of revolving door ceiling 3 is sidelong and is being put a circle permanent magnet 10, such as shown in Figure 4, permanent magnet 9 is corresponding with permanent magnet 10 positions, and magnetic pole repels each other, and it is all relative with the permanent magnet of circular fixed disk 2 as much that assurance revolving door ceiling 3 rotates to any position, and to guarantee that the two permanent magnet has enough relative areas, the repulsion of generation is stabilized in revolving door body 5 in the curved wall 6.

Claims

1, a kind of repulsion formula magnetic suspension revolving door device, it is characterized in that: the both sides, doorway that revolving door is installed at needs are installed with bearing post, the bearing post inboard is fixed with the revolving door curved wall, circular fixed disk is being supported in the bearing post top, it around the fixed disk outstanding downwards edge, edge installed inside one circle permanent magnet, fixed disk center are a circle hole, and a circle permanent magnet is also installed at periphery top, circle hole; Top, fixed disk circle hole is placed with circular hanging scaffold, circular hanging scaffold is a projective table type, and boss is upside down little and firmly be connected with the ceiling of revolving door, and a circle permanent magnet is installed on the anchor ring in the major part of boss, and corresponding with the permanent magnet at periphery top, fixed disk circle hole, and magnetic pole repels each other; In addition, the ceiling of revolving door week side one circle permanent magnet and corresponding with the permanent magnet of inboard, fixed disk edge is also arranged, and magnetic pole repels each other, below firmly is connected with revolving door.
