摘要:
Methods and system for automatically operating a continuous mining machine. One method includes automatically operating at least one actuator to position a platform supporting a cutterhead at a predetermined starting position, automatically operating the at least one actuator to advance the platform toward a cutting face until the cutterhead contacts the cutting face and at least one indicator of a physical force between the cutterhead and the cutting face exceeds a predetermined value, and automatically saving at least one coordinate of the cutting face to a computer-readable medium, the at least one coordinate based on a parameter of the at least one actuator when the indicator exceeds the predetermined value.

摘要:
A mining machine (100) including a cutting mechanism comprising (104) an arm (108) having an arm end (112), a disc cutter (116) adapted to engage the material to be mined and mounted on said arm end (112) by a disc cutter assembly for eccentrically driving the disc cutter, wherein said disc cutter (116) is driven by said arm into the material to be mined, and wherein said arm further includes a main portion (304), and a wrist portion (308) pivotally attached to the main portion, said main portion including two spaced apart horizontal main plates (322), and a support (330) rotatably mounted and extending between the two main plates (322), said wrist portion (308) being pivotally mounted on the support (330), and pivotable relative to the main portion (304) by rotating about the support (330).
摘要:
Die Erfindung betrifft eine Antriebsvorrichtung für rotierende, mit Oszillationsüberlagerung arbeitende Werkzeuge, aufweisend ein Antriebsgehäuse (11), eine drehbar in diesem gelagerte Trägerhülse (15), eine drehbar in dieser gelagerte Antriebswelle (13), Werkzeugträger (16A,16B) zur Aufnahme von Bearbeitungewerkzeugen und eine Oszillationserregereinrichtung zur Erzeugung der Oszillationsüberlagerung für den oder die werkzeugträger (16A,16B). Um bei den Antriebsvorrichtungen bzw. den mit Schlagüberlagerung arbeitenden Werkzeugen die Lagerung und Abdichtung von Antriebswelle und Trägerhülse zu vereinfachen und die Standzeit der Antriebsvorrichtungen und insbesondere der mit diesen ausgestatteten Werkzeuge zu erhöhen, weist erfindungsgemäß die Oszillationserregereinrichtung für jeden Werkzeugträger (16A,16B) wenigstens zwei Zwischenwellen (30) auf, die jeweils über einen Exzenterteil (32) mit dem Werkzeugträger (16A,16B) gekoppelt sind und synchron antreibbar sind.
摘要:
A rock excavating or cutting device (10) including a disc cutter (12) that is driven by drive means (20) to rotate in an oscillating and nutating manner by driving the disc cutter (12) about separate oscillating and nutating axes AA, BB which are angularly offset from one another and which intersect at a point ahead of the disc cutter (12).
摘要:
A rock cutting machine including a boom (11) rotatably mounted at a proximal end to a chassis (13) adapted to be placed adjacent a rock face (14) to be cut. The boom extends from the chassis to a distal end adjacent the rock face. A longitudinal boom axis (21) extends between the proximal and the distal ends of the boom and a cutting device (10) is pivotally mounted about a pivot axis (20) adjacent the distal end of the boom. The pivot axis enables wrist movement about the pivot axis by a drive mechanism (29) and is offset from the longitudinal axis of the cutting device (23).
