Description

The invention relates to a revolving door assembly with a compact, easy to install electric drive.
Are known revolving door drives that have an asynchronous motor with downstream transmission. This is typically a multi-stage transmission (worm gear, timing belt stages) are used. To drive the turnstile a multi-tooth shaft is used, which is firmly connected to the drive unit. This drive system is first installed in the ceiling construction. Then the turnstile including the door wings is mounted. A disadvantage of this design is that an order of assembly must be maintained by the fixed drive shaft. When replacing a defective drive unit, the components must be disassembled in reverse order. The disadvantage, therefore, is that for the replacement of a defective drive unit, the entire turnstile must be dismantled.
There are also known direct drives for revolving doors, which dispense with a transmission.
Such direct drives are for example in EP2754823A2 or EP2754821A2 known.
It is an object of the present invention to provide a revolving door arrangement, which comprises a compact drive with cost-effective production and can be assembled and disassembled with little effort.
The object is achieved by the features of the independent claims. The dependent claims relate to advantageous embodiments of the invention.
Thus, the object is achieved by a revolving door assembly for a turnstile. The turnstile comprises at least two door leaves and is rotatable about an axis of rotation, wherein along the axis of rotation an axial direction and perpendicular to the axial direction a radial direction are defined. The revolving door assembly comprises an electric drive, designed as electronically commutated Vielpolmotor with a stator comprising a laminated stator core and a plurality of coils, and a rotor comprising a rotor core and a plurality of permanent magnets. The rotor can be arranged coaxially with the axis of rotation and connected to the turnstile for direct, gearless drive. Furthermore, the revolving door arrangement comprises a An adapter unit comprising (i) at least one ceiling mounting member for securing the adapter unit to a ceiling structure, (ii) fixing members for fixing underbody elements to the adapter unit, and (iii) at least one drive mounting member for fixing the operator to the adapter unit.

The turnstile of a revolving door usually includes a plurality of door leaves, which are arranged in a star shape to the axis of rotation. The drive according to the invention, designed as Vielpolmotor, has a stator with a certain number of coils and a rotor. The rotor comprises a rotor lamination stack mounted on a rotor disk. Likewise, the stator comprises a stator disk, wherein a stator lamination stack is mounted on the stator disk. The stator can be composed of several disc plates. The stator disk and the rotor disk are opposite, so that between the two disks, the stator laminations and the rotor laminations are arranged. In the rotor a plurality of permanent magnets are arranged radially inside the rotor plate.

The entire adapter unit may be attached to the ceiling structure prior to assembly of the drive. The ceiling construction comprises, for example, two beams. The adapter unit is attached to these two carriers via two ceiling mounting elements. In this case, the adapter unit can be positioned accurately positioned in at least one plane prior to assembly of the drive. For example, the ceiling construction has grooves. Sliding blocks are guided in these grooves. The ceiling fasteners are screwed to the groove stones.

In the prior art, the revolving doors are threaded in a particular order in a corresponding ceiling mount at the revolving doors. The disadvantage of this is that this assembly order must be adhered to and the individual ceiling element can not be disassembled individually. According to the invention, individual fixing elements are located on the adapter unit. At each fixing element, a suspended ceiling element can be fixed. The individual underside element is thus fixed to a fixing element on its radial inner side. This allows assembly and disassembly of individual suspended ceiling elements. As a result, individual components of the drive are accessible without having to disassemble all the ceiling elements.

Only after the adapter unit is connected to the ceiling construction via the ceiling fastening elements is the drive lifted from below to the adapter unit. For connection between the adapter unit and drive at least one drive fixing element is provided. Since already the adapter unit with respect to the ceiling construction is fixed, the entire, heavy unit of drive and adapter unit must not be moved. The at least one drive attachment element is in particular designed such that a predefined and exact positioning between drive and adapter unit is provided.
The adapter unit is advantageously constructed in several parts and includes an adapter plate for this purpose. At least one ceiling mounting element, for example in the form of an angle, is fastened to this adapter plate. Furthermore, the multiple fixing elements are located on the adapter plate. The fixing elements are distributed in particular on the radially outer circumference of the adapter plate.
In the assembled state, the stator is advantageously located on the underside of the adapter plate. The adapter plate thus covers the top of the stator. At the top of the stator, at least one plug may be arranged to contact the stator. Advantageously, a corresponding recess is provided in the adapter plate, so that the plug is accessible from above through the recess.

The single fixing element comprises a pivotable or a sliding support. This edition is so displaced or pivoted that the individual ceiling element is inserted from below and fixed by appropriate pivoting or moving the support. The suspended ceiling element then rests on the support.
The support can either carry exactly one underlay element or the support is arranged between two lower ceiling elements, so that each two Unterdeckenelemente rest on a support. The support is connected for example via a bolt or a screw to the main body of the fixing element. As a result, the support is pivotable. Alternatively, it is also possible that the support in a slot of the body is inserted and pulled out. Furthermore, it is possible to connect the support via a corresponding joint with the main body of the fixing element. In all these variants, it is possible to separately mount and dismount the individual suspended ceiling element. The single fixing element comprises a Aushebeschutz. This Aushebeschutz is arranged opposite the support. The blanket element is arranged between the Aushebeschutz and the support. This Aushebeschutz is necessary so that any locking of the door are not manipulated can. The locking unit of the turnstile is often in the closed revolving door, ie, above the ceiling. The fixing elements with the Aushebeschutz ensure that in the case of vandalism the Unterdeckenelemente can not be raised, creating a manipulation of the locking unit is avoided.

The distance between Aushebeschutz and support is adjustable to the appropriate thickness of different suspended ceiling elements. In particular, it is provided for this purpose that the Aushebeschutz is a screwed into the main body of the fixing element screw. By appropriate screwing or unscrewing the distance can thus be adjusted to the appropriate thickness. As an alternative to screw, a spring-loaded element can also be inserted into the base body. In particular, material thicknesses between 1 mm and 10 mm should be considered here. As a result, a variety of ceiling variants can be used. Furthermore, the adjustability ensures that in the presence of drafts the Unterdeckenelemente not rattle.
Between the drive and the adapter unit is advantageously located, in addition to the drive attachment element, at least one Vorfixiereinheit. By means of this Vorfixiereinheit the drive can be fixed to the adapter unit, even before the drive attachment element is set. The adapter unit is relatively lightweight and can be easily attached by a man to the ceiling structure. The prefixing unit also allows one-man assembly of the drive on the adapter unit. The drive only has to be lifted from below to the adapter unit. The prefixing unit is designed so that the drive engages. Then the drive is fixed to the adapter unit and the drive attachment elements, such as screws, can be set.
The prefixing unit advantageously comprises an extension and a recess corresponding to the extension. The extension is formed, for example, on the adapter unit. The corresponding recess is located in the stator of the drive. Alternatively, it is also possible that the extension is located on the stator of the drive and this extension is inserted into a corresponding recess in the adapter unit. Between extension and recess a locking, clamping, plug or hook connection is formed. It is understood that there are very different configurations for the prefixing unit. The decisive factor is that the drive can engage with the adapter unit. The prefixing unit does not have to carry a load during operation, since the at least one drive fastening element is set before startup.

It is preferably provided that the drive attachment element is a screw connection.

The revolving door arrangement is preferably characterized by a connecting element, preferably a multi-toothed shaft. The connecting element is used for non-rotatably connecting the rotor to the turnstile on the axis of rotation, wherein in the adapter unit and in the stator recesses are provided and wherein the connecting element can be inserted from above into the rotor and the turnstile through the recesses.

In conventional revolving doors, the turnstile is driven by a multi-toothed shaft, which is firmly connected to the drive unit. This drive system is first installed in the ceiling construction, then the turnstile incl. The door is mounted. A disadvantage of this arrangement is that an assembly sequence must be maintained by the drive fixed drive shaft. When replacing a defective drive unit, the components must be disassembled in reverse order. So the complete turnstile has to be disassembled for the replacement of a defective drive unit.

In the context of the invention is advantageously provided that a connecting element is inserted from above through the adapter unit and through the stator in the rotor. For this purpose, the adapter unit and the stator have aligned recesses. Through these recesses, the connecting element, preferably a multi-toothed shaft, can be inserted from above into the rotor and thus also into the turnstile. In reverse order, the connecting element can be pulled upwards. As a result, the drive between the adapter plate and the turnstile can be pulled out. Disassembly of the entire hub is therefore no longer necessary.

For power and data transmission between the rotating portion of the revolving door and the fixed portion of a slip ring body is advantageously used. This slip ring body can be inserted from above into the inserted connection element. Also, to replace the slip ring body requires no disassembly of components, since the inclusion of the slip ring body is integrated into the connecting element and is accessible from above.

The drive has a technical surface. When installed in the revolving door, this surface is advantageously covered by a visible cover. In particular, the cover is multi-part and can thus be assembled and disassembled without disassembly of the turnstile. The multi-part cover, which usually has a coated surface, can be mounted as the last component of the revolving door. Thus is excluded damage to the surface and given the possibility of interchangeability. Preferably, the cover is attached to the fixing elements.
The invention further comprises an assembly method for the revolving door assembly just described, characterized by the following steps in a given order: (a) attaching the adapter unit to the ceiling structure by means of the at least one ceiling fixture element, (b) fixing the drive to the adapter unit by means of the at least one drive fixture element , and (c) fixing the subcabulum members to the fixation members. It is provided that between step a and b of the drive via the at least one Vorfixiereinheit is fixed to the adapter unit. It is further provided that by pivoting or moving the support of the respective fixing element, the respective lower ceiling element is individually and independently of the adjacent lower ceiling elements mountable and disassembled.

The following is based on the Fig. 1 to 10 an embodiment of an inventive revolving door 100 according to the present invention explained.

Fig. 1 shows an isometric view of a revolving door 1 of the revolving door assembly 100. The revolving door 1 comprises a turnstile 2. This hub 2 has four door leaves 3. The door leaves 3 are each angled at 90 ° to each other. The turnstile 2 is arranged rotatably about a rotation axis 4. The axis of rotation 4 extends in the axial direction 5. Perpendicular to the axial direction 5, a radial direction 6 is defined. Around the axial direction 5, a circumferential direction 7 is defined.

On the turnstile 2, a drive 8 is arranged. This drive 8 is designed as electronically commutated Vielpolmotor. The rotor 17 (s. Fig. 2 ) This drive 8 is connected coaxially to the axis of rotation 4 with the turnstile 2. This allows the drive 8 a direct and gearless drive the turnstile. 2

Fig. 2 shows a section through the revolving door 100. Of the revolving door 1, only the drive 8 is shown.

The drive 8 comprises a stator 10 and the rotor 17. Like Fig. 1 shows, the drive 8 is arranged above the turnstile 2. In this case, the rotor 17 is located between the turnstile 2 and the stator 10.

Fig. 2 shows a rotatably connected to the rotor 17 connecting element 9, designed as a multi-toothed shaft. About this connecting element 9, the turnstile 2 is rotatably connected to the rotor 17.

The stator 10 comprises a stator disk 12. A stator laminated core 11 is arranged on the outer circumference of the stator disk 12. The individual coils 13 of the stator 10 are stuck on this stator laminated core 11.

Each coil comprises a bobbin 14, for example made of plastic. On this bobbin 14 are the windings 15 of the single coil thirteenth

The rotor 17 comprises a rotor disk 34. This rotor disk 34 lies opposite the stator disk 12. Between the two discs 34, 12 is the stator lamination with the coils 13th arranged. At the outer periphery of the rotor disk 34, a rotor core 18 is arranged. Radially within the rotor core 18, a plurality of permanent magnets 19 are arranged on the rotor core 18.

In the region of the axis of rotation 4, a thrust bearing 20 and a radial bearing 21 are formed between the stator 12 and the rotor disk 34. In the illustrated embodiment, the thrust bearing 20 and the radial bearing 21 are formed as sliding bearings.

The in Fig. 1 shown drive 8 is part of the revolving door assembly 100. This revolving door assembly 100 is in section in Fig. 2 shown. The revolving door arrangement 100 includes, in addition to the drive 8, an adapter unit 101. This adapter unit 101 is used to mount the drive 8 to a superordinate ceiling construction 103. In the example shown, the ceiling construction 103 comprises two parallel horizontal beams.

The adapter unit 101 comprises at least one ceiling mounting element 102. This is formed here as a right angle bent angle. The ceiling fastening element 102 is fastened in the profiles of the ceiling construction 103 via a screw connection and corresponding sliding blocks.

The adapter unit 101 further comprises an adapter plate 107. With this adapter plate 107, the ceiling mounting member 102 is firmly connected, for example, welded.

At the periphery of the adapter plate 107 a plurality of fixing elements 104 of the adapter unit 101 are attached. These fixing elements 104 each serve to secure a suspended ceiling element 105.

The adapter unit 101 further comprises at least one drive fastening element 106. This is designed here as a screw connection and serves for fastening the drive 8 to the adapter unit 101, in particular to the adapter plate 107.

Fig. 2 and 3 show preferred Vorfixiereinheiten 110. These Vorfixiereinheiten 110 here include a snap hook. This makes it possible to lift the drive 8 from below to the adapter plate 107. In this case, the pre-fixing units 110 engage and the drive 8 is pre-fixed to the adapter unit 110. Then designed as screw driving fasteners 106 can be set.

Furthermore, the illustration in FIG Fig. 3 a preferred connection recess 111 in the adapter plate 107. About this connection recess 111 is an electrical contact, in particular a plug, within the drive 8 accessible from above.

Fig. 4 shows in detail one of the fixing elements 104. In particular, the representations in the Fig. 5 . 6 and 7 It can be seen that in each case with a fixing element 104, a lower ceiling element 105 is attached to the adapter unit 101. For the sake of clarity, only one of the twelve sub-ceiling elements 105 is shown.

The fixing element 104 according to Fig. 4 comprises a support 108 fixed to the base body. This support 108 is fastened to the base body, for example, by means of a screw and can be pivoted. The support 108 is a Aushebeschutz 109 arranged opposite. The Aushebeschutz 109 is in this case a screwed into the body screw. Depending on how far the Aushebeschutz 109 is screwed, the distance to the support 108 changes. As a result, different thickness ceiling elements 105 can be used.

In particular, the pivotable support 108 makes it possible to separately mount individual ceiling elements 105 and dismantle.

As the Fig. 2 . 5 . 6 . 7 and 8th show, the lower side of the drive 8 is covered by a cover 112 to form here a visually appealing conclusion. In particular, it is provided that this cover 112 is attached to the adapter unit 101, for example to the fixing elements 104.

Fig. 5 shows with the two arrows that via a corresponding design of the ceiling mounting elements 102, the adapter unit 101 can be accurately positioned even before the assembly of the drive 8 in the position. As a result, it is possible to fix the relatively light component, the adapter unit 101, in the correct position. Only then is the drive 8 attached to the adapter unit 101.

Fig. 6 shows that the already described connecting element 9 can be inserted through the adapter plate 107 from above. Of course, this connecting element 9 can also be pulled upwards. This makes it possible to separate the drive 8 from the turnstile 2, without disassembling the turnstile 2.

Fig. 7 shows that in the interior of the connecting element 9, a slip ring body 113 can be used. This slip ring body 113 serves to transmit power and / or data to the rotating parts of the revolving door arrangement 100.

Fig. 8 again shows for clarity the bottom of the adapter unit 101 with mounted drive 8 and plugged connection element 9. In the complete revolving door assembly 101 puts this connector 9 in the upper end of the turnstile 2 (s. Fig. 1 ).

Fig. 9 shows how a light ring 114 on the adapter unit 101, in particular on the adapter plate 107, can be attached. Regardless of the exact design of the drive 8, the adapter plate 107 can be made slightly larger than the drive 8. This makes it possible to arrange radially outside the drive 8 still a lighting, for example in the form of the light ring 114.

Fig. 10 shows a light ring 114 which is fixed to the rotor core 18 of the drive 8 and rotates during operation of the revolving door 1. This light ring 114 is powered by the slip ring body 113 with electricity.
