Description

Wägevorriebtung fir Hebezeuge zum Wägen einer an einem Flasebenzuge hängenden Last. Den Gegenstand vorliegender Erfindung bildet eine Wägevorrichtung für Hebezeuge, und zwar soll eine an einem Flaschenzug hängende Last in einfacher Weise unter Vermeidung der Übelstände gewogen werden. Ein Nachteil vieler dieser an sich bekannten Wägevorrichtungen für Hebezeuge u. dgl. ist, daß durch die unvermeidliche und veränderliche Seilsteifigkeit beträchtliche Fehler im Wägeresultat entstehen können. Andere Vorrichtungen erfordern besondere Hilfsmittel zur vorübergehenden übertragung des Lastgewichtes auf eine Waage, welche während des Aufzugs ganz ausgeschaltet ist.Weighing drive for hoists for weighing one on a bottle pull hanging load. The subject of the present invention is a weighing device for hoists, namely a load hanging on a pulley system in a simple Be weighed wisely while avoiding the evils. A disadvantage of many of these known weighing devices for hoists and the like. Is that due to the inevitable and variable rope stiffness, considerable errors occur in the weighing result can. Other devices require special temporary aids Transfer of the load weight to a scale, which is completely switched off during the elevator is.

Diesen bekannten Einrichtungen gegenüber unterscheidet sich der Gegenstand der vorliegenden Erfindung nun dadurch, daß das feste Trum des die Last tragenden Flaschenzuges, welches man bis jetzt immer mit einem festen Punkte, wie beispielsweise dem Krankopfe, verbindet, mittelbar oder unmittelbar mit der Waage selbst gekuppelt ist.The subject differs from these known devices of the present invention now in that the fixed strand of the load-bearing Pulley, which one has always been with a fixed point, such as the crane head, connects, indirectly or directly coupled to the scale itself is.

Der Gegenstand der Erfindung ist auf der .Zeichnung in einem Ausführungsbeispiel dargestellt, und zwar ist dabei i der Lasthaken einer losen Rolle 2. Das feste Trum 3 des Seilzuges ist an einem auf einer Schneide 4 gelagerten Hebel 5 befestigt, welcher in geeigneter Weise auf eine nicht dargestellte Waage wirkt; von der Rolle 2 läuft das Seil anderseits über eine feste Scheibe 6, während das holende Trum 7 zur Trommel eines Hebezeugs geführt ist.The object of the invention is shown on the .Drawing in an embodiment, namely i is the load hook of a loose roller 2. The fixed strand 3 of the cable is attached to a lever 5 mounted on a cutter 4, which is suitably on a scale, not shown, acts; On the other hand, the rope runs from the roller 2 over a fixed pulley 6, while the hauling strand 7 is guided to the drum of a hoist.

Sobald die Last irei am Haken i hängt, i * w d das Lastgewicht zur Hälfte auf die r Waage übertragen, so daß sich das Gewicht zu jeder Zeit ablesen läßt. Will man den Einfluß -des mit der Höhe der Last veränderlichen Kabelgewichtes ausschalten, so ermittelt mä n das Gewicht immer bei einer. vorher bi'stimru"#Höhe der Last, für welche das durch die Seillänge bedingte Taragewicht bekannt ist. Am genausten ermittelt man das Gewicht bei stillhängender Last, weil während der Heb- und SenkbemFegung die Spannungen im festen Trum nicht ganz unveränderlich sind.Once the load is suspended on the hook irei i, i * w d the load weight equally between the r balance transfer so that the weight can be read at any time. If you want to switch off the influence of the cable weight, which changes with the height of the load, you always determine the weight with one. beforehand bi'stimru "# Height of the load, for which the tare weight due to the rope length is known. The weight is most precisely determined when the load is suspended, because during the lifting and lowering movements the tensions in the fixed strand are not completely unchangeable.

Gegebenenfalls kann man das feste Trum 3 auch direkt an einer fest gelagerten Federwaage 8 befestigen, wie in der Zeichnung punktiert angedeutet ist.If necessary, the fixed strand 3 can also be attached directly to a fixed spring balance 8 , as indicated by dotted lines in the drawing.

Zwecks Schonung der Waage empfiehlt es sich, letztere zu entlasten, solange nicht gewogen werden soll, was mit einem einfachen Hebelsystem erreichbar ist.In order to protect the balance, it is advisable to relieve the latter, as long as you do not want to weigh what can be achieved with a simple lever system is.

. Durch optische, elektrische oder sonstige Vorrichtungen kann man das Wägeresultat an geeigneter Stelle, beispielsweise im Kranhause, ablesbar machen. . Optical, electrical or other devices can be used to make the weighing result readable at a suitable location, for example in the crane house.
