Definitions
- the invention relates to a propulsion or extraction machine with rotatably mounted on a cantilever arm mining tools, wherein the cantilever arm is pivotally articulated about at least one substantially horizontal axis and fixed to a pivotable about a substantially vertical pivot axis slewing gear.
- Swing mechanisms for partial cutting machines can be found, for example, in AT 321 851 B.
- the pivoting of the slewing gear about a substantially vertical axis by means of a rack, which meshes with a ring gear disc takes place.
- the known arrangement required a certain height because of the sprocket plate separately corresponding bearing components were provided, which absorb the reaction forces of the Schrämarmes in particular during its pivoting about a substantially horizontal axis in the height direction.
- the known construction has provided the toothed rack in a position arranged essentially transversely to the machine longitudinal direction, so that, in addition to a relatively high overall height, a displaceability of such a slewing mechanism in the machine longitudinal direction can not be achieved without collision with further components of a propulsion or mining machine, such as anchor drilling machines. and setters or the like. Was possible.
- a cutting arm was pivoted in the height direction about a substantially horizontal axis, wherein the arrangement of the pivot axis was provided on a carriage, which in turn was itself movable relative to the machine frame in the machine longitudinal direction.
- a simple conversion of such a machine to different mining tools was not given in this training.
- the invention now aims to further develop a propulsion and extraction machine of the type mentioned in that in a simple way different mining tools and different slewing geometries can be used at the same time the lowest possible height of each swing used in each case.
- the aforementioned jacking and mining machine is designed so that the slewing gear is connected to a sprocket whose Zahnkranz with a guided in the machine longitudinal direction rack is in lateral engagement and that on the opposite side of the rack, a pivot drive for the pivoting of the cantilever arm is articulated about the substantially horizontal axis.
- a pivot drive for the pivoting of the cantilever arm is articulated about the substantially horizontal axis.
- such a construction makes it possible to dimension the sprocket disk sufficiently large so that the sprocket itself can be designed as storage, which can safely absorb the introduced by pivoting the boom in the vertical direction forces. Since the sprocket disc ensures a correspondingly secure storage with the appropriate diameter, the slewing mechanism itself can be designed with a relatively low overall height and removed at any time by disassembly of the sprocket disc bearing shell parts and be replaced by other pivoting tools with different swing geometry.
- the design is advantageously such that the slewing mechanism is mounted on a slide bearing the rack guide, wherein on such a carriage, which carries the slewing, after removal of the ring gear and the swing mechanism at any time another type of storage for a cantilever can be set.
- a bearing member instead of a slewing mechanism, which allows VerSchwenkung of the boom about a substantially vertical axis, a bearing member are attached, in which only a substantially horizontal axis is provided for pivoting a cantilever arm, in which case the pivot drive to a suitable Position of the carriage can be supported to accommodate correspondingly high forces safely.
- a particularly low height can be maintained, with a significant advantage in the formation of the swing with a substantially vertical pivot axis with only one side extending rack as a drive for the sprocket lies in the pivot drive for VerSchwenkung a boom in Provide height direction on the opposite side of the rack so that here again correspondingly high forces can be absorbed at low height.
- the construction according to the invention is developed such that the carriage is displaceably guided on the machine frame on a pipe and rod guide arranged parallel to the rack guide in the machine longitudinal direction. Overall, a slide is created in this way, which ensures a high level of lateral support at low height and thus can safely absorb tipping forces.
- the locking elements can be connected either with a bearing ring which engages over the toothed ring disc or with a bearing component for fixing a pivot bearing for pivoting the extension arm about a substantially horizontal pivot axis.
- the sprocket disc overlapping bearing ring thus represents a particularly stable element of a bearing which safely absorbs the tilting forces of the slewing with pivoting about a substantially vertical axis, the solubility of such a sprocket cross-ring bearing ring allows quick and easy removal of the entire pivot bearing.
- the training is advantageously made so that the carriage at least one bearing for the attack of an adjusting to VerSchwenkung a boom is arranged about a substantially horizontal axis.
- Such a separate mounting for the attack of an adjusting cylinder for the pivoting only about a substantially horizontal axis makes it possible to choose the most favorable geometry with a low overall height.
- the training is such that at least one additional bearing for the pivotable in the height direction articulation of a loading ramp is arranged on the carriage.
- the training is advantageously made so that the carriage is designed as a box section with a bottom plate and side walls and in that the side walls comprise or receive the locking members for the bearing ring of the slewing mechanism which engages over the sprocket disk or the bearing component for the vertical pivoting of a boom arm.
- the force profile formed in this way can form a substantially annular cavity for receiving the ring gear disc serving as a bearing disc, so that the assembly is facilitated with simultaneous simple centering of the components.
- the training is advantageously made such that in the box cavity of the carriage a bearing disk for support the sprocket plate and a central journal for supporting the pivot bearing of the sprocket plate are arranged.
