Definitions

• the invention relates to a drive device for a revolving door in which door leaves rotate about a center point within diametrically opposed fixed drum walls. These door leaves are driven by a drive motor, which is usually an electric motor.
• a revolving door of the aforementioned type has become known from international patent application WO 82/03104, in which the middle part, i.e. a drive unit is present in a closed interior.
• a drive wheel is provided on a central axis located in the fulcrum and does not go all the way to the ground and is driven by an electric motor via further drive wheels.
• a revolving door of this type can be found in GB 2,052,612 A.
• the drive motor with its gearbox is mounted between the upper trusses in such a way that its drive wheel comes into engagement with a turntable fastened below the trusses.
• the rotating vanes located between the outer end walls are mounted on the rotating ring in a rotatably mounted manner.
• the device for the electric drive of a security gate describes the German utility model 88 12 507.6.
• a drive unit is installed on a fixed drive shaft above the turnstile, which is carried out by a three-phase motor and a worm gear with self-locking.
• the transmission has a very high transmission ratio, which has the consequence that the security gate is virtually blocked in the de-energized state, ie it is stationary.
• the three-phase motor is energized, it is possible to hold the door leaves with a correspondingly high force in order to avert danger.
• the object of the invention is to provide a drive concept which, from an economical point of view, permits a wide variety of assembly options with one and the same drive unit.
• a drive device consisting of an electric motor with a worm gear
• which are designed such that a flat structural unit is formed, i.e. the electric motor is located next to the worm gear, so that the overall height as such is very low compared to the units known from the prior art.
• An axis passes through the worm gear, which can either be flanged to an existing center column or to a rotating inner part of a revolving door via a coupling, or the drive axis as such can also run directly through the worm gear and via appropriate power transmission means, e.g. Feather key to be connected to each other.
• the drive device with its electric motor is controlled by a control unit equipped with a microprocessor, which works together with a frequency converter.
• control units are usually activated by external sensors, which can work in a wide variety of ways and inform the revolving door that a person wants to pass through this area safely.
• Another peculiarity of the subject matter of the invention is that a cost reduction in the manufacture of the revolving door is achieved by the fact that the otherwise necessary bearing for the rotating leaves can be dispensed with in an underfloor installation, since the drive unit with the worm gear is capable of carrying the loads of the turned part.
• the worm gear can also be designed in several stages, ie a first worm gear can be flanged directly to the drive motor, its output shaft being operatively and positively connected to a flat worm gear lying next to it.
• a direct coupling between the drive unit and the rotating part can thus take place without an additional drive means.
• the axis can easily go to the base plate and thus simultaneously establish the non-positive and positive connection when penetrating the worm gear.
• the drive device according to the invention thus represents a cost-effective alternative to the prior art, since all possible types of installation can be implemented with a drive unit, and at the same time further advantageous aspects come into play such that, for example, the headband is significantly lower than in conventional doors due to the flat design of the drive unit can be.
• the same drive unit can be used both with and without a central column.
• Figure 1 General view of a revolving door
• FIG. 1 shows a revolving door, the rotating part 1 of which consists of an interior 5 provided with glass panes by four curved walls. At these corners of the interior 5, the rotary wing 3 are attached.
• the entire rotating part 1 with the rotating blades 3 and the interior 5 is driven by an electric motor, which in the exemplary embodiment is connected to the interior 5 in a positive and positive manner under a cover 22 such that it rotates the entire rotating part in the direction of rotation 17 can spend.
• the outer frame of the moving parts is formed by the fixed drum walls 2.
• the upper end also forms a ceiling 7, to which a headband 12 connects, which is continued to the building ceiling.
• the revolving door is controlled by sensors 15 which report an approach of a person and thus bring the rotating part 1 into rotation in order to allow the person (s) to enter the building.
• an electric motor 11 with its drive unit 10 has been installed under the cover 22.
• the revolving door has an interior space 5 and thus the headband 12 can be significantly smaller than if a known drive unit were located within the headband 12.
• mount the drive unit 10 in the area of the ceiling 23 within the interior 5 in order to likewise set the rotating part 1 in rotation here.
• these two types of installation described above are only possible if a correspondingly large interior space is available. If the interior is not available, other types of installation can also be carried out with the object according to the invention without having to use another drive, namely in the underfloor installation or above the ceiling 7, within the headband 12.
• this headband 12 does not have to be designed as high in the object according to the invention due to the design of the drive unit 10 as is the case with conventional revolving doors. Due to the choice of a worm gear 9, which has a flat design, with the flange-mounting of an electric motor 11, which is located on the side of the worm gear 9, a drive unit 10 has been created which has a very low overall height.
• a further gear can also be used between the electric motor 11 and the worm gear 9 in order to achieve the desired speed of the door or the torque required for the rotating leaf 3.
• the worm gear 9 can be designed such that a bore 21 for receiving an axle drive is present, the power transmission between the axle and the worm gear preferably being realized via a feather key.
• the worm gear 9 it is also possible for the worm gear 9 to be selected such that there is a possibility of flange-mounting a coupling 14 to which the rotating part 1 can in turn be articulated.
• the object according to the invention is also suitable for underfloor installation in such a way that a floor opening 13 can already be made on site in the floor 6, in which a trough 18 is inserted.
• This trough 18 is closed on all sides, so that no disruptive influences can act on the drive unit 10.
• the drive unit 10 with the worm gear 9 is placed on the tub floor 24, for example via a console 16, as shown in FIG.
• a clutch 14 has been used, which is connected on the one hand to the worm gear 9 and on the other hand to the axis 8 in a non-positive and positive manner.
• the center column 4 can either be connected directly to the axis 8 or a connection can also be carried out here via a further coupling element.
• the individual rotary wings 3 of the revolving door are mounted on the center column 4.
• the floor opening 13 is closed by a cover 20 flush with the floor 6.
