Description
S-g für Schraubenverbindungen, insbesondere für den UntertagebergbauS-g for screw connections, especially for underground mining
Die Erfindung bezieht sich auf die Sicherung gegen Verschmutzung für Schraubenverbindungen, insbesondere für den Untertagebergbau.The invention relates to the protection against pollution for Screw connections, especially for underground mining.
Seit neuerer Zeit ist für die Explosionssicherung in untertägigen .Arbeitsräumen, wie zum Beispiel Strecken, seitens der Bergbehörde vorgeschrieben, daß diese Strecken über ihre ganze Fläche gepastet werden müssen· Es handelt sich bei diesen Pasten um eine Chlortnagneeiua- bzw. Chlorkalzium-Paste, jjiese Pasten wirken sehr aggressiv auf die stählernen Grubenausbauteile und insbesondere auf die Schrauben. Im Untertagebergbau ist es in gewissen Strecken erforderlich und notwendig, den Streckenausbau dem Abbaufortsehritt folgend zu rauben und wieder an einer anderen Stel 1 e~"zü~verwenden. Nachdem in solchen gepasteten Strecken der Streckenausbau einige Zeit eingesetzt ist, hat es sich herausgestellt, daß insbesondere durch das aggressive Verhalten der Pasten die Schraubenmuttern auf den Schraubenbolzen unlösbar zugerostet sind. Man hilft sich zur Zeit damit, daß man hingeht und die Schrauben sprengt. Dieses hat den Nachteil, daß die gesprengten Schrauben nicht mehr verwendet werden dürfen, daß zum Sprengen dieser Schraubenverbindungen ein erheblicher Zeit- und Lohnaufwand erforderlich ist, und daß auch die für das Sprengen benötigten Spezialwerkzeuge sehr teuer sind und schon nach kürzester Zeit wegen ihrer zu gn ien Beanspruchung unbrauchbar und ersetzt werden müssen.Recently, the mining authorities have stipulated for explosion protection in underground workrooms, such as routes, that these routes must be pasted over their entire surface Pastes have a very aggressive effect on the steel pit support parts and especially on the screws. In underground mining it is required and necessary in certain routes to rob the Streckenausb au the Abbaufortsehritt following and at another Stel 1 e ~ "IG ~ use. Once in such pasted stretches of roadway support some time is used, it has been found, That the nuts on the screw bolts are inextricably rusted due to the aggressive behavior of the pastes. At the moment, one helps oneself by going there and blowing the screws. This has the disadvantage that the blown screws can no longer be used for blowing These screw connections require a considerable amount of time and labor, and that the special tools required for blasting are also very expensive and after a very short time they are unusable and have to be replaced because of their excessive stress.
Die vorliegende Erfindung stellt sich die Aufgabe, den Schraubenverbindungen eine Sicherung gegen Verschmutzung zu geben Erfindungsgemäß wird das dadurch ersieht, daß über die angezogenen Schraubenmuttern eine Kunststoffkappe bzw. eine Kappe aus einem anderen elastischen oder auch nicht elastischen Material gestülpt, aufgeschoben oder aufgetrieben wird, und zwar so, daß diese Schutzkappe einen sicheren Halt auf der Schraubenmutter hat. Hierbei ist es auch sehr günstig, wenn diese Schutzkappe mit einem guten Fett gefüllt wird, so daß die Schraubenverbindung durch diese Maßnahme absolut gegen Verschmutzung geschützt und gesichert ist.The present invention has the task of the screw connections to give a safeguard against pollution sees that a plastic cap or plastic cap is placed over the tightened nuts. a cap made of another elastic or non-elastic material is put on, pushed on or driven on, in such a way that this protective cap has a secure hold on the screw nut. It is also very beneficial if this protective cap is filled with good fat, like this that the screw connection is absolutely protected and secured against contamination by this measure.
Ein Ausführungsbeispiel dieser Erfindung ist anhand der Zeichnung näher erläutert. Hierbei ist mit a) das Profil des Streckenausbaubogens, mit b) der Schraubenbolzen, mit d) die Mutter und mit d) die Schutzkappe bezeichnet.An embodiment of this invention is explained in more detail with reference to the drawing. Here, with a) the profile of the route extension arch, with b) the screw bolt, with d) the nut and with d) the protective cap.
