Definitions
- the invention relates to a weight compensation device for driving a lifting gate, for position-dependent compensation of the weight of a door leaf of the lifting gate, according to the independent claim.
- Lifting gates and integrated weight compensation devices are known from the prior art.
- the DE 40 15 214 A1 a lift gate with a lamellar armor with bendable lamellas.
- the lifting gate disclosed therein comprises two guideways disposed on the two opposite sides of the door opening, and a louvered armor with louvers which are spaced apart on hinge bands such that the hinge lugs engage within a space between the adjacent louvers.
- this lifting gate is designed as an industrial lifting gate in the sense of a high-speed door.
- Such lifting gates are designed as rolling doors that close or release the walk-through or passable door openings.
- tension springs to compensate for the weight of the individual slats, which form the door leaf, are used.
- tension springs have the disadvantage that they only have a lifetime of about 200,000 strokes.
- torsion springs have an even shorter life, from about 30,000 to 40,000 strokes.
- tension springs commonly used also have a further disadvantage, namely that they require a lot of space in heavy gates, which must be available in particular on the sides of the door opening. If a frame of the door is not wide enough to accommodate juxtaposed tension springs, of which the necessary supporting spring force is provided, so there is still the possibility to arrange them one behind the other, but both types affect the efficient use of space in the area of a lifting gate.
- the US 1,416,071 A discloses a counterbalance device having features of the characterizing portion of the independent claim herein.
- the compression spring in said application here is a threaded shaft surrounding arranged in a lubricated tube. One end of the spring rests against a slide which is guided axially movably on the threaded shaft, and the other end of the spring bears against a collar fixed to the threaded shaft.
- the carriage rotates with the tube while the threaded shaft does not rotate with the collar.
- the threaded shaft rotates together with the collar while the carriage with the tube is not rotated.
- the GB 570,469 A discloses a counterbalancing device comprising a tension spring surrounding a shaft, one end of which is fixed to an axially movable carriage and the other end of which is fixed to a shaft collar. Shaft and spring are positioned in a tube. Both the carriage and the shaft collar are not rotated by the shaft during operation while the tube rotates.
- At least one compression spring is provided, which is arranged so that it supports the opening movement.
- Such compression springs can endure a higher load over many years compared to tension and especially torsion springs, without a failure occurring after a relatively short operating time or maintenance work having to be carried out at an early stage. Tests carried out on certain compression springs have shown that no significant spring deformations have occurred after one million strokes.
- a solution according to the invention is therefore not only inexpensive and durable, but also allows the advantage of a particularly simple and efficient construction.
- the compression spring is arranged in a hollow cylindrical guide member, wherein the hollow cylindrical guide member for supporting a rotational movement of the power transmission device is mounted rotatably or non-rotatably on a frame. This allows an efficient use of spring force in a compact design.
- the force of the compression spring can also be used particularly efficiently as a support torque for counterbalancing the weight of the door leaf, since the compression spring is supported in a force-transmitting manner on a guide element-fixed base part and an actuating element which can move translationally relative to the guide element.
- the compression spring is coupled to a motion conversion device which uses the force acting in the longitudinal direction of the compression spring to support a rotational movement of the door leaf lifting or lowering power transmission device.
- the motion converting device therefore utilizes the force storable in a compression spring to transmit a assisting torque to the transmission.
- the compression spring is arranged substantially horizontally, preferably transversely to the lifting or lowering direction of the door leaf. As a result, a good space utilization can be achieved.
- the weight compensation device can be realized in a particularly compact manner when the door leaf wound up in the raised state surrounds a cavity in which the pressure spring and / or the movement-changing device is arranged.
- the guide element forms a non-rotatable hollow cylinder or the guide element forms the drive shaft configured as a hollow shaft.
- An advantageous embodiment is characterized in that the drive shaft is in operative relationship with the actuating element, which is displaceable by the compression spring in a longitudinal direction of the drive shaft.
- a gear-like training can be achieved when the actuator is torque-transmitting coupled to the drive shaft, preferably such that a movement of the actuating element along the longitudinal direction forces a torque transmission from the actuator to the drive shaft.
- the adjusting element is guided longitudinally displaceably within the hollow shaft, preferably in a groove on the inside of the hollow shaft, which preferably extends substantially in the longitudinal direction.
- the groove is present on the adjusting element and corresponding counter-same projections on the inside of the hollow shaft are present.
- the adjusting element is designed as a spindle nut, it is possible to fall back on a proven conversion element. High forces can be transmitted and used over a long time resilient components.
- a further advantageous embodiment is characterized in that in the drive shaft at least one of these subdividing elastic coupling is formed.
- a flexible coupling in particular in the manner of a dog clutch, is advantageous in order to compensate for mechanical over-determination between lateral bearings which are used for supporting the drive shaft. It is possible to use on one side of the dog clutch only radial bearings, whereas on the other side of the dog clutch, a thrust bearing and a radial bearing are combined. It is also possible for a plurality of elastic couplings, such as dog clutches, to be used axially one after the other, and the corresponding bearings are arranged outside these elastic couplings.
- the invention also relates to a lifting gate, in particular an industrial lifting gate, which has a door leaf, with a drive, such as a motor and a weight compensating device according to the invention explained above.
- a drive such as a motor and a weight compensating device according to the invention explained above.
- Such an engine may be, for example, an electric motor or a hydraulic or pneumatic motor. Internal combustion engines are also possible drive units.
- a viewing window is present that releases the view of the spindle nut. In this way, the adjustment of the individual elements relative to each other can be controlled.
- the viewing window extends along the longitudinal direction and is preferably aligned horizontally.
- Such a horizontal alignment is also offered by the fact that the hollow shaft, or the drive shaft, is normally arranged extending over the door opening in the horizontal direction.
- the spindle nut has an end plate, for which a mounting position is marked in the viewing window, it can be easily done with untrained personnel adjustment and assembly.
- the coupling between the motor and spindle nut can be canceled by the spindle nut preferably by hand and / or using a crank in a desired mounting position can be moved, in which the coupling can be restored.
- a method is advantageous that uses the viewing window to spend after a decoupling of the corresponding elements, the end plate in the planned position and then restore the coupling.

Die Erfindung betrifft eine Gewichtsausgleichsvorrichtung für einen Antrieb eines Hubtores, zum positionsabhängigen Kompensieren der Gewichtskraft eines Torblattes des Hubtores, gemäß dem unabhängigen Anspruch.

Alternativ eingesetzte Torsionsfedern haben sogar eine noch geringere Lebensdauer, von etwa 30.000 bis 40.000 Hüben.Alternatively used torsion springs have an even shorter life, from about 30,000 to 40,000 strokes.
Die häufig eingesetzten Zugfedern haben auch noch einen weiteren Nachteil, nämlich dass sie bei schweren Toren viel Bauraum benötigen, welcher insbesondere an den Seiten der Toröffnung zur Verfügung stehen muss. Ist eine Zarge des Tores nicht breit genug, um nebeneinander angeordnete Zugfedern aufzunehmen, von welchen die notwendige unterstützende Federkraft zur Verfügung gestellt wird, so besteht zwar noch die Möglichkeit diese hintereinander anzuordnen, doch beeinträchtigen beide Arten die effiziente Platzausnutzung im Bereich eines Hubtores.The tension springs commonly used also have a further disadvantage, namely that they require a lot of space in heavy gates, which must be available in particular on the sides of the door opening. If a frame of the door is not wide enough to accommodate juxtaposed tension springs, of which the necessary supporting spring force is provided, so there is still the possibility to arrange them one behind the other, but both types affect the efficient use of space in the area of a lifting gate.

Selbst das Einsetzen von Hydrospeichern bei Industriehubtoren gehört nicht zu einer optimalen Ausgestaltung, da solche Hydrospeicher verwendenden Konstruktionen teuer und aufwändig sind.Even the use of hydraulic accumulators in industrial lifting doors does not belong to an optimal design, since such hydraulic accumulator-using constructions are expensive and expensive.

Die
Es ist Aufgabe der vorliegenden Erfindung zuvor genannte Nachteile aus dem Stand der Technik zu vermeiden und eine kostengünstige und langlebige Gewichtsausgleichsvorrichtung zur Verfügung zu stellen, welche bei Toren, bei denen folienartige Torblätter oder mehrere gelenkig miteinander verbundene, vorzugsweise starre Segmente gehoben werden, wie etwa Spiraltoren oder bei das Trommelprinzip nutzenden Toren, einsetzbar ist.It is an object of the present invention to avoid the above-mentioned disadvantages of the prior art and to provide a low-cost and durable weight compensation device, which are lifted at gates, in which foil-like door leaves or a plurality of hingedly interconnected, preferably rigid segments, such as spiral doors or with the drum principle using gates, can be used.
Diese Aufgabe der Erfindung wird nach dem unabhängigen Anspruch dadurch gelöst, dass zumindest eine Druckfeder vorhanden ist, die so angeordnet ist, dass sie die Öffnungsbewegung unterstützt. Solche Druckfedern können über Jahre hinweg eine im Vergleich zu Zug- und besonders Torsionsfedern höhere Belastung ertragen, ohne dass schon nach einer relativ geringen Einsatzzeit ein Versagen auftritt oder frühzeitig Wartungsarbeiten durchgeführt werden müssen. Bei durchgeführten Tests an bestimmten Druckfedern haben sich nach einer Million Hübe keine wesentlichen Federverformungen eingestellt.This object of the invention is achieved according to the independent claim in that at least one compression spring is provided, which is arranged so that it supports the opening movement. Such compression springs can endure a higher load over many years compared to tension and especially torsion springs, without a failure occurring after a relatively short operating time or maintenance work having to be carried out at an early stage. Tests carried out on certain compression springs have shown that no significant spring deformations have occurred after one million strokes.
Eine erfindungsgemäße Lösung ist daher nicht nur kostengünstig und langlebig, sondern ermöglicht auch den Vorteil einer besonders einfachen und effizienten Konstruktion.A solution according to the invention is therefore not only inexpensive and durable, but also allows the advantage of a particularly simple and efficient construction.
Weiterhin ist die Druckfeder in einem hohlzylinderförmigen Führungselement angeordnet, wobei das hohlzylinderförmige Führungselement zum Unterstützen einer Drehbewegung der Kraftübertragungseinrichtung rotierbar oder drehfest an einem Gestell angebracht ist. Dies ermöglicht eine effiziente Federkraftnutzung bei kompakter Bauweise.Furthermore, the compression spring is arranged in a hollow cylindrical guide member, wherein the hollow cylindrical guide member for supporting a rotational movement of the power transmission device is mounted rotatably or non-rotatably on a frame. This allows an efficient use of spring force in a compact design.
Die Kraft der Druckfeder lässt sich zudem besonders effizient als Unterstützungsdrehmoment zum Gewichtsausgleich des Torblattes nutzen, da sich die Druckfeder an einem führungselementfesten Basisteil und einem relativ zum Führungselement translatorisch verschieblichen Stellelement kraftübertragend abstützt.The force of the compression spring can also be used particularly efficiently as a support torque for counterbalancing the weight of the door leaf, since the compression spring is supported in a force-transmitting manner on a guide element-fixed base part and an actuating element which can move translationally relative to the guide element.
Vorteilhafte Ausführungsformen sind in den Unteransprüchen beansprucht und werden nachfolgend näher erläutert.Advantageous embodiments are claimed in the subclaims and are explained in more detail below.
So ist es von Vorteil, wenn die Druckfeder an eine Bewegungswandeleinrichtung gekoppelt ist, die die in Längsrichtung wirkende Kraft zur Druckfeder zur Unterstützung einer Drehbewegung der das Torblatt hebenden oder senkenden Kraftübertragungseinrichtung einsetzt. Die Bewegungswandeleinrichtung nutzt daher die in einer Druckfeder speicherbare Kraft, um ein Unterstützungsdrehmoment an die Kraftübertragungseinrichtung zu verbringen.Thus, it is advantageous if the compression spring is coupled to a motion conversion device which uses the force acting in the longitudinal direction of the compression spring to support a rotational movement of the door leaf lifting or lowering power transmission device. The motion converting device therefore utilizes the force storable in a compression spring to transmit a assisting torque to the transmission.
Es ist ferner von Vorteil, wenn die Druckfeder im Wesentlichen horizontal angeordnet ist, vorzugsweise quer zur Hub- oder Senkrichtung des Torblattes. Dadurch lässt sich eine gute Bauraumausnutzung erreichen.It is also advantageous if the compression spring is arranged substantially horizontally, preferably transversely to the lifting or lowering direction of the door leaf. As a result, a good space utilization can be achieved.
Besonders kompakt lässt sich die Gewichtsausgleichsvorrichtung realisieren, wenn das im gehobenen Zustand aufgewickelte Torblatt einen Hohlraum umgibt, in dem die Druckfeder und/oder die Bewegungswandeleinrichtung angeordnet ist.The weight compensation device can be realized in a particularly compact manner when the door leaf wound up in the raised state surrounds a cavity in which the pressure spring and / or the movement-changing device is arranged.
Um besonders einfach Spiraltore und Trommeltore realisieren zu können, ist es von Vorteil, dass das Führungselement einen drehfesten Hohlzylinder ausbildet oder das Führungselement die als Hohlwelle konfigurierte Antriebswelle ausbildet.To be able to realize spiral doors and drum doors in a particularly simple manner, it is advantageous that the guide element forms a non-rotatable hollow cylinder or the guide element forms the drive shaft configured as a hollow shaft.
Ein vorteilhaftes Ausführungsbeispiel ist dadurch gekennzeichnet, dass die Antriebswelle mit dem Stellelement in Wirkbeziehung steht, welches durch die Druckfeder in einer Längsrichtung der Antriebswelle verschiebbar ist.An advantageous embodiment is characterized in that the drive shaft is in operative relationship with the actuating element, which is displaceable by the compression spring in a longitudinal direction of the drive shaft.
Eine getriebeartige Ausbildung lässt sich erreichen, wenn das Stellelement drehmomentübertragend mit der Antriebswelle gekoppelt ist, vorzugsweise derart, dass eine Bewegung des Stellelements entlang der Längsrichtung eine Drehmomentübertragung von dem Stellelement auf die Antriebswelle erzwingt.A gear-like training can be achieved when the actuator is torque-transmitting coupled to the drive shaft, preferably such that a movement of the actuating element along the longitudinal direction forces a torque transmission from the actuator to the drive shaft.
Um ein Rotieren des Stellelementes zu vermeiden, wenn beispielsweise die Antriebswelle rotiert, ist es von Vorteil, wenn das Stellelement innerhalb der Hohlwelle längsverschieblich geführt ist, vorzugsweise in einer Nut auf der Innenseite der Hohlwelle, die sich vorzugsweise im Wesentlichen in Längsrichtung erstreckt. Allerdings ist es auch möglich, dass die Nut am Stellelement vorhanden ist und entsprechende gegengleiche Vorsprünge auf der Innenseite der Hohlwelle vorhanden sind.In order to avoid a rotation of the actuating element, for example, when the drive shaft rotates, it is advantageous if the adjusting element is guided longitudinally displaceably within the hollow shaft, preferably in a groove on the inside of the hollow shaft, which preferably extends substantially in the longitudinal direction. However, it is also possible that the groove is present on the adjusting element and corresponding counter-same projections on the inside of the hollow shaft are present.
Wenn das Stellelement als Spindelmutter ausgebildet ist, so lässt sich auf ein bewährtes Wandelelement zurückgreifen. Hohe Kräfte lassen sich dadurch übertragen und über eine lange Zeit belastbare Komponenten verwenden.If the adjusting element is designed as a spindle nut, it is possible to fall back on a proven conversion element. High forces can be transmitted and used over a long time resilient components.
Es ist besonders zweckmäßig, wenn die Spindelmutter über einen Gewindeeingriff mit der Antriebswelle gekoppelt ist. Die Federkraft der Druckfeder lässt sich dann besonders einfach unterstützend auf die Antriebswelle aufprägen.It is particularly useful when the spindle nut is coupled via a threaded engagement with the drive shaft. The spring force of the compression spring can then impress particularly easily supportive on the drive shaft.
Ein weiteres vorteilhaftes Ausführungsbeispiel ist dadurch gekennzeichnet, dass in der Antriebswelle zumindest eine diese unterteilende elastische Kupplung ausgebildet ist. Eine solch elastische Kupplung, insbesondere nach Art einer Klauenkupplung, ist von Vorteil, um eine mechanische Überbestimmtheit zwischen seitlichen Lagern, die zum Lagern der Antriebswelle eingesetzt sind, auszugleichen. Es ist möglich, auf der einen Seite der Klauenkupplung nur Radiallager zu verwenden, wohingegen auf der anderen Seite der Klauenkupplung ein Axiallager und ein Radiallager miteinander kombiniert sind. Auch ist es möglich, dass axial hintereinander mehrere elastische Kupplungen wie Klauenkupplungen verwendet sind und die entsprechenden Lager außerhalb dieser elastischen Kupplungen angeordnet sind.A further advantageous embodiment is characterized in that in the drive shaft at least one of these subdividing elastic coupling is formed. Such a flexible coupling, in particular in the manner of a dog clutch, is advantageous in order to compensate for mechanical over-determination between lateral bearings which are used for supporting the drive shaft. It is possible to use on one side of the dog clutch only radial bearings, whereas on the other side of the dog clutch, a thrust bearing and a radial bearing are combined. It is also possible for a plurality of elastic couplings, such as dog clutches, to be used axially one after the other, and the corresponding bearings are arranged outside these elastic couplings.
Die Erfindung betrifft auch ein Hubtor, insbesondere ein Industriehubtor, das ein Torblatt aufweist, mit einem Antrieb, wie einem Motor und einer vorstehend erläuterten erfindungsgemäßen Gewichtsausgleichsvorrichtung. Ein solcher Motor kann beispielsweise ein Elektromotor oder ein hydraulischer bzw. pneumatischer Motor sein. Auch Verbrennungskraftmaschinen sind mögliche Antriebsaggregate.The invention also relates to a lifting gate, in particular an industrial lifting gate, which has a door leaf, with a drive, such as a motor and a weight compensating device according to the invention explained above. Such an engine may be, for example, an electric motor or a hydraulic or pneumatic motor. Internal combustion engines are also possible drive units.
Es ist dann ferner von Vorteil, wenn in der Hohlwelle ein Sichtfenster vorhanden ist, dass den Blick auf die Spindelmutter freigibt. Auf diese Weise wird die Justierung der Einzelelemente relativ zueinander kontrollierbar.It is then also advantageous if in the hollow shaft, a viewing window is present that releases the view of the spindle nut. In this way, the adjustment of the individual elements relative to each other can be controlled.
Damit ein Nachjustieren beziehungsweise ein Erstjustieren der Einzelelemente besonders einfach kontrolliert werden kann, ist es von Vorteil, wenn sich das Sichtfenster entlang der Längsrichtung erstreckt und dabei vorzugsweise horizontal ausgerichtet ist. Eine solche Horizontalausrichtung bietet sich gerade auch dadurch an, dass die Hohlwelle, beziehungsweise die Antriebswelle, normalerweise über der Toröffnung in Horizontalrichtung verlaufend angeordnet ist.So that a readjustment or Erstjustieren the individual elements can be particularly easily controlled, it is advantageous if the viewing window extends along the longitudinal direction and is preferably aligned horizontally. Such a horizontal alignment is also offered by the fact that the hollow shaft, or the drive shaft, is normally arranged extending over the door opening in the horizontal direction.
Wenn die Spindelmutter eine Endscheibe aufweist, für die eine Montageposition im Sichtfenster markiert ist, so kann auch mit ungelerntem Personal eine Justierung und eine Montage einfach durchgeführt werden.If the spindle nut has an end plate, for which a mounting position is marked in the viewing window, it can be easily done with untrained personnel adjustment and assembly.
Es ist ferner von Vorteil, wenn bei einer Montage des Hubtores die Koppelung zwischen Motor und Spindelmutter aufhebbar ist, um die Spindelmutter vorzugsweise händisch und/oder unter Einsatz einer Kurbel in eine gewünschte Montageposition verbringbar ist, in der die Koppelung wieder herstellbar ist. In diesem Zusammenhang ist auch ein Verfahren von Vorteil das das Sichtfenster nutzt, um nach einer Entkoppelung der entsprechenden Elemente die Endscheibe in die geplante Position zu verbringen und danach die Koppelung wieder herzustellen.It is also advantageous if, during assembly of the lifting door, the coupling between the motor and spindle nut can be canceled by the spindle nut preferably by hand and / or using a crank in a desired mounting position can be moved, in which the coupling can be restored. In this context, a method is advantageous that uses the viewing window to spend after a decoupling of the corresponding elements, the end plate in the planned position and then restore the coupling.
