Description

Befestigungszange Für die bekannten zangenartigen Aufhängevorrichtungen im Grubenbetrieb hat sich durch die neuerlichen Verordnungen der Bergämter über Sicherheitsvorrichtungen unter Tage die Anwendung von Sperr- und Haltevorrichtungen an Lastträgern jeglicher Art notwendig gemacht.Fastening pliers For the known pliers-like suspension devices in mining operations has become over due to the recent ordinances of the mining authorities Underground safety devices the use of locking and holding devices made necessary on load carriers of any kind.

In Zeichnung A und B sind für die bekannte Grubenbefestigu:ngszange schematische Darstellungen dieser Sicherung durch die Anwendung von Sperrklinken gegeben.In drawings A and B , schematic representations of this securing system through the use of pawls are given for the well-known pit fastening pliers.

Hierbei sind gemäß Zeichnung A die Zangenschenkel i an den unter dem Gelenk befindlichen Schmalseiten als Zahnflächen z ausgebildet, während an den über dem Gelenk liegenden Breitseiten die durch Nieten .3 befestigten Fallklinken ,1 je nach der Spannung des Zangenmaules veränderlich in die Zahnflächen 2 eingreifen und damit das Herabfallen der Traglast beim Anlüftenoder bei Schrumpf des Haltepunktes unmöglich machen, weil die Klinken durch ihr Gewicht selbsttätig diesen Veränderungen folgen. Zur Erhöhung des Eingriffs können die in Zeichnung A schraffiert dargestellten. Verstärkungen q.c oder die Blattdruckfed in 4 d Anwendung finden. In Zeichnung B ist der rechte Schenkel i über dem Gelenk .an der unteren Schmalseite als Zahnfläche a ausgebildet. Der andere Schenkel trägt unterhalb des Gelenks ran der Breitseite auf Schraube 3 die Sperrklinke q., welche durch Flügelmutter 5 je nach Stellung des Zangenmaules zwischen zwei Zähnen der Zahnfläche a eingestellt und festgestellt wer- den kann. An Stelle der Flügelmutter und Schraube kann auch durch das Gewicht q.a und die Druckfeder .1b die Klinkenfeststellung selbsttätig erfolgen. Here, according to drawing A, the pliers legs i are designed as tooth surfaces z on the narrow sides located under the joint, while the pawls attached by rivets so that it is impossible for the load to fall when lifting or shrinking the holding point, because the pawls automatically follow these changes due to their weight. To increase the engagement, those shown hatched in drawing A. Reinforcements qc or the leaf compression spring in 4 d can be used. In drawing B the right leg is i above the joint. on the lower narrow side designed as a tooth surface a. The other The thigh rests below the joint On the broad side of screw 3 the pawl q., which by wing nut 5 depending on the position of the forceps mouth between two teeth of the Tooth surface a can be set and determined can. Instead of the wing nut and Screw can also by the weight qa and the compression spring .1b the pawl lock take place automatically.
