Abstract

The hydraulic powered key is used for undoing or tightening heavy nuts or screws with a large mechanical advantage. It has a hydraulic power system which operates an open ended or ring spanner, or an Allan key or square tang key. The key may be operated either a clockwise or anti-clockwise, with or without ratchets or pawls. A slot is used to bolt a spanner head in place at any point according to lever arm needed. The driving arm is moved by a hydraulic cylinder, with a pumping arm as actuator.

Description

HYDRAULIK - Kraft schlüsselHYDRAULICS - power key

B e s c h r e i b u n g Bei dem Anmeldungsgegenstand handelt es sich um einem mit Hydraulikkraft betriebenen Schlüssel.Dieser ist allgemein und generell überall dort einsetzbar wo besonders festzitzende Schrauben oder Muttern gelost oder festgezogen werden müssen und hierbei Körperanstrengungen vermieden werden sollten oder können.Ein Beispiel wären sehr fest sitzende Kfz.-Radmuttern.D e c e r i n g e The subject of the registration is a key operated with hydraulic power, this is general and general Can be used anywhere where particularly tight screws or nuts have been loosened or must be tightened, avoiding physical exertion Should or can. An example would be very tight car wheel nuts.

Aber auch im Maschinenbau und überhaupt überall dort wo gleiche oder ahnliche Kraftprobleme auftreten,werden diese in ihrer Gesamtheit durch dem Anmeldungsgegenstand vollkommen beseitigt Figur 1 ) zeigt ein Beispiel eines solchen Hydraulik-Schlüssels.But also in mechanical engineering and in general wherever the same or Similar force problems occur, these are in their entirety by the subject of the application completely eliminated Figure 1) shows an example of such a hydraulic key.

Teil a) ist je nach Grösse ein kompaktes stabiles Träderteil as dem die dazugehörenden Zusatzteile befestigt werden.Das Langloch b) nimmt den durch Verschieben einstellbaren Anschlag auf*Der Anschlag kann je nach Verwendungszweck variabel ausgeführt sein.c) Der Anschlußvierkant ist je nach Größe des Schlüssels entsprechend stabil und in Normgröße gehalten.Part a) is, depending on its size, a compact, stable part of the wheel as dem The associated additional parts are attached. The elongated hole b) takes the through Move adjustable stop to * The stop can depending on the purpose variable. c) The connection square is depending on the size of the key accordingly stable and kept in standard size.

Er dient zur Aufnahme der zu verwendenden Stecknuse.Der Anschlußvierkait ist auf links oder rechtsdrehung verschiebbar.Er ist drehbar gelagert und wird direkt oder über eine Ratsche oder Pasten durch einen Mitnehmer e) bewegt.Der Mitnehmer wird durch eines Hydraulik-Druckzylinder bewegt bzw.It is used to hold the socket to be used can be moved to the left or right, can be rotated and is direct or moved via a ratchet or pastes by a driver e). The driver is moved resp.

in die eingestellte Drehrichtung getrieben.Über einen Pumpzylinder f) kann nun mit geringstmöglichem körperlichem Kraftaufwand,über den Druckzylinder der die eigentliche Druckkraft bildet,jede auch noch so fest sitzende Schraube oder Mutter spielend gelöst werden.Andersherum kann durch einen aufgesteckten Drehmomentschlüssel jede Schraube oder Mutter beliebig festgezogen werden ohne wesentliche körperliche Kraftanstrengung.Driven in the set direction of rotation via a pump cylinder f) can now with the least possible physical effort, over the pressure cylinder which forms the actual pressure force, no matter how tight a screw or The nut can be loosened with ease, or the other way around with an attached torque wrench Any screw or nut can be tightened at will without any substantial physical Physical exertion.

Eine Dauerdrehrichtung ohne Absetzen des Schlüssels wird durch die Ratsche e) in sofern erreicht. daß von Raste zu Raste jeweils der Ölrückfluß automatisch ausgelöst wird und insofern der Mitnehmer immer wieder auf Ausgangsstellung begracht wird.Der Ölrückfluß kann auch manuell erfolgen.A continuous direction of rotation without removing the key is enabled by the Ratchet e) if reached. that from notch to notch the oil backflow is automatic is triggered and insofar as the driver is always on the starting position The oil return can also be done manually.

Alles in allem gibt es für diesen Hydraulikschlüssel keinerlei Kraftprobleme mehr und es können individuell je nach Größe und Auslegung größte Drücke zum Losen sowie Festziehen von Schrauben oder Muttern erzielt wird den.All in all, there are no force problems whatsoever with this hydraulic wrench more and, depending on the size and design, the greatest pressures can be released as well as tightening screws or nuts is achieved.
