DEUTSCHESGERMAN
Es sind pneumatische Hebevorrichtungen od. dgl. bekannt, bei denen am oder im Zylinder Sperrklinken vorgesehen sind, die als Sicherung gegen ein ungewolltes Absinken der Last dienen. Diese Sperrklinken in Form von einfachen Hebeln oder Winkelhebeln kornmen entweder durch Federdruck oder ihr Eigengewicht zum Einrasten und damit zum Sperren. Das Lösen geschieht von Hand oder mittels einer Mehrzahl von Hebeln, Gelenken und Federn, die durch die Bewegung des Lastträgers gesteuert werden.Pneumatic lifting devices or the like are known in which pawls are provided on or in the cylinder that serve as a safeguard against unintentional lowering of the load. These pawls in In the form of simple levers or angle levers, either through spring pressure or their own weight to snap into place and thus to lock. The loosening is done by hand or by means of a plurality of levers, joints and springs that are controlled by the movement of the load carrier.
Der Erfindung liegt nun die Aufgabe zugrunde, eine einfache, weniger störanfällige Klinkensperre für in einem senkrechten Rohr od. dgl. bewegte Lastträger zu schaffen. Die Erfindung besteht darin, daß der Lastträger mit winkelförmigen Sperrklinken und das Rohr an den Sperrstellen mit zwei eine Ringrippe bildenden Ringnuten versehen ist. Die Sperrklinken können auch T-förmig ausgebildet sein, wobei dann das Rohr an den Sperrstellen mit drei zwei Ringrippen bildenden Ringnuten versehen ist.The invention is now based on the object of a simple, less prone to failure ratchet lock for To create moving load carriers in a vertical tube or the like. The invention is that the Load carrier with angular pawls and the tube at the locking points with two forming an annular rib Annular grooves is provided. The pawls can also be T-shaped, in which case the Tube is provided at the locking points with three annular grooves forming two annular ribs.
Durch diese Vorrichtung ist es möglich, die Last an den gewünschten, mit Sperrnuten versehenen Stellen gegen ungewolltes Absinken zu sichern, wobei sowohl das Einrasten als auch das Lösen der Sperre durch die Bewegung des Lastträgers erfolgt und dabei lediglich das Eigengewicht der Sperrklinken ausgenutzt wird.With this device it is possible to place the load at the desired points provided with locking grooves to secure against unintentional lowering, whereby both the engaging and the loosening of the lock through the movement of the load carrier takes place using only the dead weight of the pawls will.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Es zeigenTwo exemplary embodiments of the invention are shown in the drawing. Show it
Fig. 1 bis 4 verschiedene Arbeitsstellungen der Sperrvorrichtung,Fig. 1 to 4 different working positions of the locking device,
Fig. 5 eine abgeänderte Ausführungsform im Querschnitt. 5 shows a modified embodiment in cross section.
Nach Fig. 1 bis 4 liegt die Last auf einem Lastträger (Platte) 1, der in dem Rohr 2 od. dgl. mit Hilfe bekannter Mittel, z. B. durch eine Kolbenstange, gehoben und gesenkt wird. Der Lastträger 1 weist eine oder mehrere, z. B. zwei Sperrklinken 3, 4 auf, die bei 5, 6 drehbar am Lastträger 1 gelagert sind. Das feststehende Rohr 2 ist mit zwei Ringnuten 11, 12 versehen, die in geringem Abstand übereinander angeordnet sind. Der Querschnitt des Rohres 2 kann an sich beliebig sein.According to Fig. 1 to 4, the load is on a load carrier (plate) 1, which od in the tube 2. B. is raised and lowered by a piston rod. The load carrier 1 has one or more, e.g. B. two pawls 3, 4, which are rotatably mounted on the load carrier 1 at 5, 6. The stationary tube 2 is provided with two annular grooves 11, 12, which are arranged at a small distance one above the other. The cross-section of the tube 2 can be arbitrary per se.
Wird der Lastträger 1 in Richtung des Pfeiles F (Fig. 1) bewegt, so gleiten zunächst die Sperrklinken
3, 4 mit ihren Winkelschenkeln 7, 9 an der Wand 13. Steht der Lastträger 1 in Höhe der Ringnut
11, so verschwenken sich die Schenkel 7, 9 durch das Gewicht der Schenkel 8, 10 in die Ringnut hinein
(vgl. Fig. 4 oben). Wird nun von hier aus der Lastträger wieder abgesenkt (Pfeil/), so kommen die
Schenkel 7, 9 zur Anlage an die Kante 14 der Ringnut 11, während die Schenkel 8, 10 sich an
der Innenwand 13 abstützen (Fig. 2). Somit ist also Klinkensperre für in einem senkrechten
Rohr oder dergleichen bewegte LastträgerIf the load carrier 1 is moved in the direction of arrow F (Fig. 1), the pawls 3, 4 slide with their angle legs 7, 9 on the wall 13. If the load carrier 1 is level with the annular groove 11, the legs pivot 7, 9 by the weight of the legs 8, 10 into the annular groove (see. Fig. 4 above). If the load carrier is now lowered again from here (arrow /), the legs 7, 9 come to rest against the edge 14 of the annular groove 11, while the legs 8, 10 are supported on the inner wall 13 (FIG. 2). Thus, the ratchet lock is for in a vertical
Pipe or the like moving load carrier

der Lastträger 1 mit der Last gegen Absinken gesichert. the load carrier 1 secured with the load against sinking.
Soll nun die Last weiter angehoben werden, so kann dies ohne weiteres erfolgen, denn die Sperrklinken gleiten mit ihren Schenkeln 7, 9 über die Ringrippe 15 (Fig. 2) hinweg, bis sie schließlich zur gleitenden Berührung mit der Wand 13 (Fig. 3) kommen.If the load is now to be raised further, this can easily be done, because the pawls slide with their legs 7, 9 over the annular rib 15 (Fig. 2) until they finally come into sliding contact with the wall 13 (Fig. 3 ) come.
Soll die Last abgesenkt werden, und zwar ohne daß die Sperrklinken in den Ringnuten zum Einrasten kommen, so· kann dies ebenfalls ohne weiteres geschehen. Ist nämlich der Lastträger bis zu der aus Fig. 3 ersichtlichen Stellung abgesenkt worden, so wälzen sich die Sperrklinken in der aus Fig. 4 ersichtlichen Weise gegenüber den Ringnuten 11., 12 und der Ringrippe 15 ab, ohne daß ein Sperren eintritt.If the load is to be lowered without the pawls engaging in the ring grooves come, this can also be done without further ado. Namely, the porter is up to the out 3 has been lowered, the pawls roll in the position shown in FIG Way with respect to the annular grooves 11, 12 and the annular rib 15, without locking occurs.
Wird also der Lastträger 1 durchgehend gehoben oder gesenkt, so kommen die Ringnuten (Sperrnuten) nicht zur Auswirkung. Ein Sperren tritt nur dann ein, wenn der Lastträger 1 beim Anheben in Höhe der Ringnut 11 angehalten und dann ein kurzes Stück wieder abgesenkt wird oder wenn er beim Absenken unterhalb der Ringnut 11 angehalten, dann in die Höhe der Ringnut 11 angehoben und um die zum Sperren nötige Höhendifferenz wieder abgesenkt wird.If the load carrier 1 is raised or lowered continuously, the ring grooves (locking grooves) not to impact. A lock only occurs when the load carrier 1 is raised in height the annular groove 11 stopped and then a short distance is lowered again or if it is stopped when lowering below the annular groove 11, then into the The height of the annular groove 11 is raised and lowered again by the height difference required for locking will.
Die Sperrklinken können auch drei Schenkel aufweisen, d. h. T-förmig ausgebildet sein. Dabei sind dann aber drei Ringnuten erforderlich.The pawls can also have three legs, i. H. Be T-shaped. Are there but then three ring grooves are required.
Ist das Rohr 2 an einer Stelle unterbrochen (Stoßstelle), so könnte diese als Sperrnut wirken. Um ein unerwünschtes Sperren zu vermeiden, ist somit anIf the pipe 2 is interrupted at one point (joint), this could act as a locking groove. To a Avoiding unwanted locking is therefore on

jeder Stoßstelle eine zusätzliche Ringnut vorzusehen. Bei dreischenkeligen Sperrklinken wären zwei zusätzliche Ringnuten erforderlich.an additional ring groove must be provided for each joint. In the case of three-legged pawls, there would be two additional ones Ring grooves required.
Nach Fig. 5 ist das Rohr 2 mit zwei durchgehenden Längsnuten 16 versehen, die an Stelle der Ringnuten (Fig. 1 is 4) je zwei einen Zahn 20 bildende Ausfräsungen aufweisen. Der Lastträger 1 greift mit Ansätzen 17, an denen mittels der Achsen 19 die Sperrklinken 18 befestigt sind, in die Längsnuten 16 ein.According to FIG. 5, the tube 2 is provided with two continuous longitudinal grooves 16 which, instead of the annular grooves (Fig. 1 is 4) each have two cutouts forming a tooth 20. The load carrier 1 engages with Approaches 17, on which the pawls 18 are attached by means of the axes 19, into the longitudinal grooves 16 a.
