Abstract
The utility model relates to an automatic two-wing revolving door with a magnetic suspension arc motor, including a magnetic bearing and an arc motor driving device. Outer ring of the revolving door is equipped with a permanent magnet and inner ring is equipped with a permanent magnet and an electromagnet. By applying the principle of magnetic materials that the same poles mutually expel and different poles mutually attract, weight of moving parts of the two-wing revolving door is balanced by magnetic force so that the revolving part is in suspension state, and the suspension height is adjusted by controlling the magnetic flux of the electromagnet; primary winding of the arc motor installed in the inner wing and secondary winding of the arc motor installed in the outer wing interact to generate electromagnetic moment and thus make the inner wing and door wing revolve. Since the whole moving part of the revolving door is in suspension state and does not directly contact with the fixed part, there is no noise and driving force is small. Therefore, the device is of no friction, low noise, low energy consumption, simple and reliable structure. The utility model can be extensively used in various buildings such as hotels, restaurants and offices.
Description
Technical field
The utility model relates to the automatic revolving door that a kind of building uses, and especially a kind of magnetic force that utilizes makes an automatic two wings rotary door that suspends and utilize arc-shaped motor to drive.
Background technology
The large-scale both wings automatic revolving door that uses in the building, because rotating part is heavier, all be to adopt a door wing hang: Men Yi is suspended on the inner ring aluminium extruded sections, by 6-8 friction pulley and fixedly load-bearing and the transmission (friction pulley rolls along outer race track) between the outer race track that is contained in inner ring.Wherein two friction pulleys are driving wheel, are connected with motor reducer, and rotary power is provided, also load-bearing simultaneously.All the other are driven pulley, only play the load-bearing effect.There are the following problems for this structure: one, big speed ratio transmission, and noise is big, and power attenuation is big; Two, owing to adopt friction pulley, various wearing and tearing are bigger, and friction pulley and other driving member life-span are short; Three, because friction pulley and peripheral tracks contact surface are little, cause the track discontinuity, to friction pulley requirement of strength height.
On February 16th, 2005, the Chinese utility model patent manual of disclosed CN1580478 disclosed a kind of repulsion formula magnetic suspension revolving door device, this device adopts the repulsion that produces between a pair of homopolarity magnet that the motion parts of revolving door is suspended, and adopts the repulsion that produces between a pair of homopolarity magnet to make the motion parts of revolving door keep balance simultaneously.Keep the pair of magnets of balance not produce suspending power in the revolving door of this device, complex structure, adopt pair of magnets to make a suspension simultaneously, this just limits the weight and the material of revolving door motion parts, this revolving door does not have motor-driven in addition, in use will promote and could rotate by the end user, in use be very convenient.This device does not use electromagnet to regulate hoverheight (permanent magnet of fixed-site can not be regulated hoverheight) in addition.Even because every door frame door is measure-alike, weight is also different, one, the user can place different article in both wings door exhibition case, cause weight change.Two, the both wings door all has vertical hinged door, and weight also changes during the vertical hinged door action, and three, revolving door also need be regulated height when mounted, so that install.Four, cause height change during magnet chance failure.The magnetic suspension system of any motion all must be adorned arrangement for adjusting height in a word, otherwise can't normally stably work.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of magnetic suspension load-bearing that utilizes, the automatic two wings rotary door for magnetic suspension arc motor that utilizes arc-shaped motor to drive simultaneously.
For addressing the above problem, automatic two wings rotary door for magnetic suspension arc motor in the utility model, comprise magnetic suspension system and arc-shaped motor drive system, it is characterized in that: the place fixed installation column that revolving door is installed at needs, outer race track and width of cloth support are installed in the column upper end, two-layer permanent magnet is housed on the outer race track, on the rotation inner ring permanent magnet and electromagnet is housed, and is positioned at the centre of two-layer permanent magnet on the outer race track; On the axis direction of Internal and external cycle, position sensor is housed; The primary and secondary winding of arc-shaped motor is housed respectively on inner ring and outer race track.
Aforesaid automatic two wings rotary door for magnetic suspension arc motor, the hoverheight numerical value that it is characterized in that above-mentioned revolving door motion parts is sent to control circuit by position sensor, regulate magnetic flux in the above-mentioned electromagnet by above-mentioned control circuit, keep hoverheight stable.
Aforesaid automatic two wings rotary door for magnetic suspension arc motor is characterized in that above-mentioned hoverheight numerical value normal value is 5mm.
Aforesaid automatic two wings rotary door for magnetic suspension arc motor is characterized in that the alignment bearing restriction of the radially degree of freedom of above-mentioned revolving door motion parts by above-mentioned revolving door.
The beneficial effects of the utility model are: because load-bearing is to adopt magnetic suspension, and the arc electric motor transmission actual be not have the directly magnetic drives of contact.Internal and external cycle does not have any contact again, thereby has thoroughly avoided wearing and tearing except circle centre position has a centration axis holds.So its, level was long in application life, and Internal and external cycle do not have friction and exists, and door wing rotation power demand is very little, need not during the arc electric motor transmission to slow down and side steering, has further reduced power transmission loss.
In addition, the magnetic suspension arc electric motor kind of drive of the utility model employing is the scheme of a kind of novelty, science.It has abandoned all consumable accessorys, and structure is simple and reliable relatively, so maintenance cost is very low, required energy consumption is also low.Owing to cancelled deceleration, the break-in parts, noise-decreasing to greatest extent, and the inertia of whole drive system is reduced, the braking of a wing becomes rapider like this, and is more accurate.Thereby improved the two wings rotary door security performance.Because design magnetic suspension loaded area is very big, Internal and external cycle can evenly be carried in addition, improve the force way of Internal and external cycle widely, promote the rigidity of Internal and external cycle, it is more steady that a wing is rotated.This reduces noise to revolving door, and it is very useful increasing the service life.
