Description

Vorrichtung zum Absenken schwerer Lasten. Die bekannten, zur Absenkung schwerer Lasten, z. B. Brücken, verwendeten Vorrichtungen, wie Sandtöpfe und hydraulische Pressen, zeigen dien Übelstand, daß der bei ersteren benutzte Sand leicht verbackt und infolgedessen schlecht ausläuft, während bei letzteren die dauernd unter hohem Drucke stehenden Flüssigkeiten besonders sorgfältige Dichtungen notwendig machen.Device for lowering heavy loads. The well-known, for lowering heavy loads, e.g. B. bridges, devices used such as sand pots and hydraulic Pressing shows the disadvantage that the sand used in the former is easily caked and consequently runs badly, while in the latter the continuously under high Pressurized liquids make particularly careful seals necessary.

Diese Nachteile will die Erfindung vermeiden, indem sie die Verwendung von leicht schmelzbaren Stoffen. insbesondere Metalllegierungen, vorsieht, die bei b wohnlichen Temperaturen den festen Zustand aufweisen. Zum Absenken der Last wird der in geeigneten Behältern befindliche Schmelzstoff in entsprechender Weise erwärmt und der I flüssige Teil abgelassen. Das Absinken der Last kann dabei in jedem Zeitpunkte durch Unterbrechung der Wärmezufuhr und Sperren des Abflusses unterbrochen werden. Der alsdann wieder erstarrte Füllstoff trägt hierauf wie anfangs die Last, ohne besondere Dichtungen zu beanspruchen. Bei der Ausführung der Vorrichtungen gemäß der Erfindung kann ein Vorteil durch selbsttätige Regelung des Abflusses oder der Wärmezufuhr insbesondere dann erzielt werden, wenn die Lastabsenkung an mehreren Stützpunkten gleichzeitig erfolgen soll. Die Form und Anordnung der Schmelzstoffbehälter ist dabei sehr verschiedenartig, im übrigen aber für die Anwendung des Erfindungsgedankens nebensächlich.The invention aims to avoid these disadvantages by making use of it of easily meltable substances. in particular metal alloys, which at b show the solid state at comfortable temperatures. To lower the load is the melt material located in suitable containers is heated accordingly and drained the I liquid part. The load can drop at any point in time interrupted by interrupting the supply of heat and blocking the drainage. The filler, which then solidifies again, bears the load as at the beginning, without to claim special seals. When executing the devices according to the invention can be an advantage by automatically regulating the drain or the Heat supply can be achieved in particular when the load reduction on several Support points should take place at the same time. The shape and arrangement of the melt containers is very different, but otherwise for the application of the idea of the invention incidental.
