Description
Vorrichtung. zum Auswechseln von Türstöcken Beim Auswechseln von Türstöcken oder Türstockkappen in Gruben werden bisher' in die benachbarten Felder der Türstöcke je ein Hilfstürstqck gestellt,- die gegen Stöße und Firste, nicht. aber untereinander abgestützt werden können. - Diese umständliche, zeitraubende und gefährliche Arbeit, bei der die ständige Gefahr besteht, daß die Arbeiter durch Steinfall verletzt werden und nach Fortnahme des auszuwechselnden Türstockes das gelockerte Gebirge ausläuft, wodurch gegebenenfalls die Hilfstürstöcke und Zimmerungen mehrerer benachbarter Felder umgeworfen sowie Arbeiter verschüttet werden können, wird erfindungsgemäß dadurch vermieden, daß auf einer verschieb- bzw. verfährbaren Grundplatte Hebevorrichtungen zum Abstützen des zu -beiden Seiten der Türstöcke angrenzenden Gebirges und zum Auswechseln der Türstockteile angeordnet werden. Die auf der Grundplatte aufgebauten Vorrichtungen dienen für die Arbeiter gleichzeitig als Schutzvorrichtungen. Außerdem wird .die Auswechselarbeit an Türstöcken insofern wesentlich vereinfacht, als- die fest gegen das Gebirge anzudrückenden Hebevorrichtungen ein Auslaufen des Gebirges verhindern, .wodurch Lade- und -Transportarbeiten erspart werden, sowie das Entstehen von Hohlräumen- über der Zimmerung, die Veranlassung zu Streckenbrüchen und zur Ansammlung 'gefährlicher Gase geben, vermieden wird.. Zweckmäßig werden die Hebevorrichtungen hydraulisch betätigt und mit Sicherheitsventilen zum Einstellen eines Höchstdruckes versehen, um die Anpreßstücke elastisch gegen das Gebirge anzudrücken und die Aufnahme von Über-Belastungen zu vermeiden. Die.Hebevorrichtungen können auf der Grundplatte schwenkbar angebracht sein.Contraption. for changing door frames When changing door frames or door frame caps in pits have been 'in the neighboring fields of the door frames An auxiliary door is placed each - the one against the buttocks and ridges, not. but among each other can be supported. - This cumbersome, time-consuming and dangerous work, where there is a constant danger that the workers will be injured by falling stones and after removing the door frame to be replaced, the loosened mountains run out, whereby, if necessary, the auxiliary door frames and carpentry of several neighboring ones Fields can be knocked over and workers can be buried, according to the invention thereby avoided that lifting devices on a displaceable or displaceable base plate to support the mountains adjoining both sides of the door frames and to Replacing the door frame parts are arranged. The ones built on the base plate Devices also serve as protective devices for the workers. aside from that The replacement work on door frames is significantly simplified to the extent that the Lifting devices to be pressed firmly against the mountains cause the mountains to leak prevent, which saves loading and transport work, as well as the occurrence of cavities - over the carpentry, the inducement to route breaks and to Accumulation of dangerous gases is avoided. The lifting devices are expedient hydraulically operated and with safety valves for setting a maximum pressure provided to press the pressing pieces elastically against the mountains and the recording to avoid over-exertion. The lifting devices can be placed on the base plate be pivotally mounted.
