Description

Die Erfindung betrifft ein hand- oder motorisch betriebenes Hebezeug, wie Flaschenzüge oder Elektrozüge, dessen Lasträger über ein am Abtriebsende eine Antriebsrolle aufweisenden Hubgetriebe mit einem Antriebsorgan kraftschlüssig verbunden ist.The invention relates to a manually or motor-operated hoist, such as pulley blocks or electric hoists, the load carriers of which are non-positively connected to a drive element via a lifting gear having a drive roller at the output end.

Hebezeuge dieser Art werden u.a. in Lager- und Werkstätten bzw. Reparatur- und Servicebetrieben sowie zum Umschlag von Waren mit geringerem Gewicht verwendet.
Dabei sind solche Hebezeuge oft an einem an einer Kranbahn verfahrbaren Gestell, einer sog. Laufkatze befestigt oder einem als Kranbahn ausgebildeten schwenkbaren Ausleger fahrbar angeordnet.
Auch Hallenkrane, Portalkrane, Baukrane etc. sind mit derartigen Hebezeugen ausgerüstet.Lifting devices of this type are used, among other things, in warehouses and workshops or repair and service companies as well as for handling goods with a lower weight.
Such hoists are often attached to a frame that can be moved on a crane runway, a so-called trolley, or are movably arranged on a pivotable boom designed as a crane runway.
Hall cranes, gantry cranes, construction cranes, etc. are also equipped with such hoists.

Aufgrund des universellen Einsatzes solcher Hebezeuge sind ein zweckmässiges Handling und eine kompakte Bauweise bei hoher Zuverlässigkeit gefragt.
Überdies ist es von Bedeutung, dass diese Hebezeuge eine gegenüber der Aufhängeeinrichtung gleichmässige Eigengewichtsverteilung aufweisen, insbesondere wenn sie an einer hakenähnlichen Vorrichtung oder einer Oese hängend befestigt werden.Due to the universal use of such hoists, practical handling and a compact design with high reliability are required.
In addition, it is important that these hoists have an even weight distribution compared to the suspension device, especially if they are attached to a hook-like device or an eyelet.

Aufgabe der vorliegenden Erfindung ist es, ein Hebezeug nach der eingangs genannten Art auszuführen, die die oben erwähnten Vorteile aufweisen und deren Konstruktion eine hohe Betriebssicherheit gewährleistet.The object of the present invention is to implement a hoist of the type mentioned at the outset, which has the advantages mentioned above and whose construction ensures high operational reliability.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass das Hubgetriebe an der Antriebswelle des Antriebsorgans zwischen letzterem und einer Reibungskupplung angeordnet ist, wobei als Antriebsorgan ein Handantrieb in Form eines Haspelrades oder Motors, vorzugsweise Elektromotors, vorgesehen werden kann. Diese Lösungsform gestattet eine kompakte Bauweise, die Möglichkeit der direkten Einwirkung einer Bremse auf die Last und den Aufbau des Hebezeuges auf bewährten Bauelementen.According to the invention, this object is achieved in that the lifting gear is arranged on the drive shaft of the drive element between the latter and a friction clutch, wherein a manual drive in the form of a reel wheel or motor, preferably an electric motor, can be provided as the drive element. This solution allows a compact design, the possibility of a brake directly acting on the load and the construction of the hoist on proven components.

Eine besonders günstige, unabhängige Ausführungsform der erfindungsgemässen Lösung kann bei einem Hebezeug, dessen Lastträger über eine Antriebsrolle mit dem Antriebsende eines Hubgetriebes antriebsverbunden ist, erreicht werden, wenn die Antriebswelle des Antriebsorgans (bspw. Motor oder handbetätigtes Haspelrad) die Nabe eines Antriebsrades des Hubgetriebes koaxial durchsetzt und an dem Abtriebsende mit dem Antriebsrad des Hubgetriebes kraftschlüssig verbunden ist.A particularly favorable, independent embodiment of the solution according to the invention can be achieved with a hoist whose load carrier is connected to the drive end of a lifting gear via a drive roller if the drive shaft of the drive member (e.g. motor or manually operated reel wheel) coaxial with the hub of a drive wheel of the lifting gear passes through and is non-positively connected at the output end to the drive wheel of the lifting gear.

Es erweist sich als vorteilhaft, wenn die Nabe des Antriebsrades des Hubgetriebes als Hohlwelle ausgebildet ist, wodurch sich eine kompakte Bauweise und die Verwendung bekannter Getriebe bewerkstelligen lässt.It proves to be advantageous if the hub of the drive wheel of the lifting gear is designed as a hollow shaft, as a result of which a compact design and the use of known gear mechanisms can be achieved.

Als einfacher Überlastschutz sind das Abtriebsende der Antriebswelle und das Antriebsende der Hohlwelle vorzugsweise als gemeinsame Reibungskupplung ausgebildet, die sich zur Verstellung der Antriebsverbindung eignet.As a simple overload protection, the output end of the drive shaft and the drive end of the hollow shaft are preferably designed as a common friction clutch, which is suitable for adjusting the drive connection.

Überdies bildet der an der Hohlwelle befestigte eine Kupplungsteil zweckmässig den angetriebenen Teil einer Hubbremse, die durch einen mit dem Gehäuse des Hubgetriebes verbundenen stationären Teil vervollständigt wird.In addition, the coupling part fastened to the hollow shaft expediently forms the driven part of a lifting brake, which is connected to the housing of the lifting gear by a brake stationary part is completed.

Die erfindungsgemässe Ausführung gestattet es, die Hubbremse als Scheiben-, Band- oder Backenbremse auszubilden.The design according to the invention allows the lifting brake to be designed as a disc, band or shoe brake.

Als Hubgetriebe eignen sich sowohl ein Stirnrad-, Planetenrad-, Kegelrad- oder Schneckengetriebe, wobei letzteres ein- oder mehrgängig ausgebildet sein kann und aufgrund der Möglichkeit eines selbsthemmenden Reversierantriebes die Wirkung der Hubbremse begünstigt werden kann.Both a spur gear, planetary gear, bevel gear or worm gear are suitable as the lifting gear, the latter being single or multi-geared and the effect of the lifting brake being able to be favored due to the possibility of a self-locking reversing drive.

Deshalb ist es vorteilhaft, wenn das Antriebsrad des Hubgetriebes als Schneckenwelle bzw. als hohle Schneckenwelle ausgebildet ist.It is therefore advantageous if the drive wheel of the lifting gear is designed as a worm shaft or as a hollow worm shaft.

Auf einfache Weise bilden der dem Antriebsrad des Hubgetriebes zugeordnete Kupplungsteil der Reibungskupplung endseitig der Hohlwelle mittels einer ringförmigen Stirnseite mit dem an der Antriebswelle befestigten, von einer Druckfeder beaufschlagten anderen Kupplungsteil einen verstellbaren Reibungsschluss.In a simple manner, the coupling part of the friction clutch assigned to the drive wheel of the lifting gear forms an adjustable frictional engagement at the end of the hollow shaft by means of an annular end face with the other coupling part fastened to the drive shaft and acted upon by a compression spring.

Zur Ausbildung einer zweckmässigen Reibungskupplung ist es wünschenswert, wenn das der Reibungskupplung zugeordnete Ende der Antriebswelle das Ende des als Hohlwelle ausgebildeten Antriebsrades des Hubgetriebes übersteht.To form an expedient friction clutch, it is desirable if the end of the drive shaft assigned to the friction clutch projects beyond the end of the drive wheel of the lifting gear designed as a hollow shaft.

Vorzugsweise ist die Antriebswelle an dem von dem Antriebsorgan gegnüberliegenden Ende in der in dem Gehäuse des Hubgetriebe lagernden Hohlwelle gelagert.The drive shaft is preferably mounted at the end opposite the drive member in the hollow shaft mounted in the housing of the lifting gear.

Nachfolgend ist das erfindungsgemässe Hebezeug unter Bezugnahme auf die Zeichnung, auf die bezüglich aller in der Beschreibung nicht näher erwähnten Einzelheiten ausdrücklich verwiesen wird, erläutert. Es zeigen:

Die Fig. 1 bis 3 zeigen ein mit 1 bezeichnetes Hebezeug zum Anheben von Lasten mittels einer als Lastträger 2 ausgebildeten Kette, von welcher in Fig. 2 zwei in die als Antriebsrolle bestimmte, angetriebene Kettennuss 4 eingreifende Kettenglieder 3 erkennbar sind. Die Kettennuss 4 ist Teil einer Getriebewelle 5, die mit einem getriebenen Rad -hier Schneckenrad 6 eines Schneckengetriebes 7- fest verbunden ist. Die Getriebewelle 5 lagert mit beiden Enden in einem Gehäuse 8 des gesamthaft als Hubgetriebe 9 bezeichneten Schneckengetriebes 7. Mit Bezugszeichen 10 ist eine sog. Kettenablösezunge dargestellt, die die nicht dargestellten Kettenstränge trennt. Fig. 1 zeigt das Hebezeug 1 in den wesentlichen Teilen. Die Antriebswelle 11 eines Motors 12 -hier Elektromotor-, dessen Motorgehäuse 13 mit dem Gehäuse 8 des Hubgetriebes 9 verbunden ist, durchsetzt letzteres und endet etwa an einer Reibungskupplung 14, die die Antriebswelle 11 mit dem Antriebsrad 15 -hier Schneckenwelle 16- des Hubgetriebes 9 verbindet. Die Schneckenwelle 16 ist als Hohlwelle 17 ausgebildet, welche von der Antriebswelle 11 koaxial durchsetzt wird. Die Lagerung der Antriebswelle ist einerseits an den stirnseitigen Enden des Motors 12 und am gegenüberliegenden Ende in der Hohlwelle 17 vorgesehen, die ihrerseits im Gehäuse 8 des Hubgetriebes 9 gelagert ist. An den Übergangsstellen von Motor 12 und Hubgetriebe 9 sowie auf der gegenüberliegenden Seite sind zur Abdichtung des Gehäuses 8 des Hubgetriebes 9 Wellendichtungen 18 vorgesehen. Auf der Seite der Reibungskupplung 14 endet das Gehäuse 8 des Hubgetriebes 9 flanschartig zur Befestigung einer Scheibenbremse 19 und elektrischer Steuerteile (nicht ersichtlich) die durch einen am Gehäuse 8 verschraubbaren Deckel 20 geschützt sind. Die an den Enden der Antriebswelle 11 und der Hohlwelle 17 befestigte, zweiteilige Reibungskupplung 14, weist einen auf die Hohlwelle 17 aufgekeilten, axial unverschieblichen ersten Kupplungsteil 21 und einen ebenso auf der Antriebswelle 11 jedoch axial verschiebbar befestigten zweiten Kupplungsteil 22 auf, die beide ringförmig ausgebildet sind und deren einander zugewendeten Stirnseiten mit Kupplungsbelägen 23 versehen sind. Ein permanenter Reibungsschluss der Kupplungsteile 21,22 bildet eine hinter dem zweiten Kupplungsteil 22 eingespannte Druckfeder 24, die durch eine Mutter 25 auf einer als Gewinde 26 ausgebildeten Verlängerung der Antriebswelle 11 hinsichtlich Wirkung verstellbar ist. Eine Gegenmutter 27 sichert Mutter 25.
Die als Scheiben- oder Lamellenbremse 19 ausgebildete Hubbremse besteht aus einem stationären Teil 28 als Gehäuse, in welchem ringförmige Lamellen 29 gegen Verdrehen verankert sind und dem ersten Kupplungsteil 21, der die Nabe einer zwischen die stationären Lamellen 29 eintauchende angetriebene Lamelle 30 bildet. Zur bremswirksamen Betätigung der Lamellen 29,30 ist eine auch in Fig. 3 dargestellte Buchse 31 vorgesehen, die an dem flanschartigen Gehäuseende um eine senkrechte Achse schwenkbar befestigt ist und durch einen magnetisch wirksamen Bremslüfter 32 mittels Hebel 33 aus der Bremslage versetzt wird. Das Betätigen der Bremse erfolgt mittels einer nicht näher dargestellten Druckfeder, die zwischen Hebel 33 und Gehäuse 8 des Hubgetriebes 9 eingespannt ist.1 to 3 show a hoist designated 1 for lifting loads by means of a chain designed as a load carrier 2, of which two chain links 3 engaging in the driven chain sprocket 4 determined as the drive roller 4 can be seen in FIG. 2. The chain sprocket 4 is part of a gear shaft 5, which is firmly connected to a driven wheel — here worm wheel 6 of a worm gear 7. The gear shaft 5 is supported at both ends in a housing 8 of the worm gear 7, which is referred to as a lifting gear 9. Reference number 10 shows a so-called chain detaching tongue which separates the chain strands (not shown). Fig. 1 shows the hoist 1 in its essential parts. The drive shaft 11 of a motor 12, here an electric motor, the motor housing 13 of which is connected to the housing 8 of the lifting gear 9, passes through the latter and ends approximately at a friction clutch 14 which connects the drive shaft 11 with the drive wheel 15, here worm shaft 16 of the lifting gear 9 connects. The worm shaft 16 is designed as a hollow shaft 17, which is coaxially penetrated by the drive shaft 11. The bearing of the drive shaft is provided on the one hand at the front ends of the motor 12 and at the opposite end in the hollow shaft 17, which in turn is mounted in the housing 8 of the lifting gear 9. At the transition points between the motor 12 and the lifting gear 9 and on the opposite side 9 shaft seals 18 are provided for sealing the housing 8 of the lifting gear. On the side of the friction clutch 14, the housing 8 of the lifting gear 9 ends in a flange-like manner for fastening a disc brake 19 and electrical control parts (not visible). which are protected by a cover 20 which can be screwed onto the housing 8. The two-part friction clutch 14 fastened to the ends of the drive shaft 11 and the hollow shaft 17 has an axially immovable first coupling part 21 which is wedged onto the hollow shaft 17 and a second coupling part 22 which is also axially displaceably fastened to the drive shaft 11, both of which have an annular shape are and the mutually facing end faces are provided with clutch linings 23. A permanent frictional engagement of the coupling parts 21, 22 forms a compression spring 24 clamped behind the second coupling part 22, the effect of which can be adjusted by a nut 25 on an extension of the drive shaft 11 designed as a thread 26. A lock nut 27 secures nut 25.
The lifting brake designed as a disc or multi-disc brake 19 consists of a stationary part 28 as a housing in which annular plates 29 are anchored against rotation and the first coupling part 21, which forms the hub of a driven plate 30 immersed between the stationary plates 29. For the brake-effective actuation of the disks 29, 30, a bushing 31, also shown in FIG. 3, is provided, which is pivotally attached to the flange-like housing end about a vertical axis and is displaced from the braking position by a magnetically active brake fan 32 by means of lever 33. The brake is actuated by means of a compression spring, not shown, which is clamped between the lever 33 and the housing 8 of the lifting gear 9.
