Description

Die Erfindung betrifft eine Maschine, um beim Streckenvortrieb und Kohlenabbau im Flöz mittels Kreissägen Schlitze und Schräme einzuschneiden.The invention relates to a machine for driving and coal mining in the Cut slits and bevels in the seam using circular saws.

Das Neue liegt darin, daß der Vorschubschlitten mit der in die Wand eintretenden Kreissäge auf einer Konsole sitzt, die an einem Spanngestell mittels Verzahnung o. dgl. zwecks Herstellung des Schlitzes auf und ab verschiebbar ist, wobei das Sägeblatt am Umfange dadurch stärker als in der Mitte ist, daß die Kreissäge aus zwei in der Mitte dicht aufeinanderliegendeu Blättern gebildet wird, die am Umfange durch eine außen gezahnte Zwischenlage gespreizt sind. Diese Maschine zeichnet sich durch Leichtigkeit und Handlichkeit vorteilhaft aus und benötigt zum Betriebe verhältnismäßig wenig Kraft.The new thing is that the feed slide with the one entering the wall Circular saw sits on a console that is attached to a clamping frame by means of teeth or the like for the purpose of producing the slot and is displaceable, whereby the saw blade is stronger around the circumference than in the middle is that the circular saw is formed from two sheets lying close together in the middle which are spread on the circumference by an externally toothed intermediate layer. These Machine is characterized by its lightness and handiness and is advantageous relatively little power to operate.

Von zwei unter sich verbundenen gezahnten Säulen a, die durch Gewindespindel ο. dgl. vor Ort eingespannt werden können, wird eine Konsole b getragen, die durch Getriebe cs d an den Säulen α auf und ab verstellbar ist und einen Schlitten e besitzt, der sowohl den Antriebmotor h als auch die Sägei mit dem Antrieb g aufnimmt, dessen Welle g beiderseits vorsteht, um den Verhältnissen entsprechend die Schlitzsäge iinks- oder rechtsseitig des Spanngestells arbeiten zu lassen. Nach Aufstellen der Säulen α kann mittels Handspindel/ die Sägei entsprechend ihrer Arbeitsleistung in den Kohlenstoß einschneiden. Ist die Schlitztiefe erreicht, dann wird am Handrad c die Konsole b mit Motor h und -Säge i nach abwärts bewegt, und das Flöz wird von oben nach unten geschlitzt. Durch eine beliebige Anzahl dieser Schlitze wird der Vortrieb der Strekken und die Gewinnung der Kohle im Abbau nicht unwesentlich erleichtert.Of two interconnected toothed columns a, which by threaded spindle ο. Like. Can be clamped on site, a bracket b is carried, which is adjustable up and down on the columns α by gear c s d and has a carriage e , which takes both the drive motor h and the saw with the drive g , whose shaft g protrudes on both sides in order to let the slotting saw work on the left or right side of the clamping frame according to the circumstances. After setting up the pillars α can cut into the coal face by means of a hand spindle / the saw according to its work performance. When the depth of the slot is reached, the console b with the motor h and saw i is moved downwards on the handwheel c , and the seam is cut from top to bottom. Any number of these slots will make the propulsion of the stretches and the extraction of coal in the mining process not insignificant easier.

Zur Erhöhung der Schneidwirkung sind zwei Kreissägen derart miteinander verbunden, daß sie durch eine gezahnte Zwischenlage k am Umfange breiter sind als nach der Mitte (Abb. 3). Es ist somit ein Klemmen der Säge in der Kohle unmöglich gemacht. Der Unmöglichkeit, derart starke Sägen zu schränken, ist begegnet, und eine gute Schneidwirkung ist gesichert.To increase the cutting effect, two circular saws are connected to one another in such a way that they are wider around the circumference than towards the middle due to a toothed intermediate layer k (Fig. 3). This makes it impossible for the saw to jam in the coal. The impossibility of setting such strong saws has been met and a good cutting effect is assured.
