Definitions
- the invention relates to a cutting or cutting roller with variable cutting width, with which at least a lateral end face of the roller transverse to the axis of the Cutting or cutting roller two swiveling tool carriers for arranged the inclusion of cutting or cutting tools are.
- AT 388 776 B already has a cutting or cutting roller shown in which to widen the cutting width on at least one lateral end face of the roller a relative pivotable to the axis of the cutting or cutting roller Tool holder for holding cutting or cutting tools is arranged.
- Such a known training has already been trained to the extent that two Tool carrier on at least one side of the cutting roller are articulated on the outside. When extending such cutting roller extensions need the total cutting forces and in particular the forces entering the rock from the Control cylinders are taken over. In the extended Position, the cutting forces act in such a way that the hydraulic Actuating cylinders are loaded on the outside due to train the cutting forces in the direction of pivoting the pivotable Tool carriers become effective on the outside. To such To absorb forces safely should be with the known constructions double-acting hydraulic cylinder piston units, and in particular very large hydraulic cylinder piston units be used.
- the invention now aims to widen a cutting roller to create the type mentioned, in which with small hydraulic actuators found enough can be, and at which further the stability of the selected position significantly increased in the extended position becomes.
- the tool holder is tilted or swiveled the cutting tools arranged on the tool carrier or cutting tools in a side view seen in the axial direction lying position, causing each other at the working face parallel traces of cutting or cutting tools cut or broken.
- Compliance with a specific Pivotal position should ensure that the portion cut and broken material Adjustment of the swiveling tool carrier in the extended Position is changed, causing chisel wear as well should be reduced.
- one of the tool carriers carries a locking bolt, which in the extended position with a tool holder hook-shaped locking member of the other tool holder cooperates.
- a locking bolt By such a locking bolt, the with a hook-shaped locking member of the other tool holder cooperates, can be a precisely defined determine the extended position in which the tool carrier can be locked securely without causing excessive Load on the actuators for pivoting the Tool holder or to change the swivel position during operation is coming.
- the actuating cylinders are therefore relieved and a rigid bandage is formed, in which the cutting marks exactly in the extended position of the tool carrier be respected.
- the training here is particularly advantageous hit that the locking bolt is essentially extends parallel to the pivot axis of the tool carrier and that the hook-shaped locking member of the locking bolt facing mouth of the other tool holder is formed.
- the mouth opening is advantageously in the direction of Pivot axis of the tool holder arranged inclined, whereby it is ensured that in the pivoted-out position forces acting in the direction of expansion corresponding to one steep flank of the mouth are taken up against which of the locking bolts is supported.
- the training is taken advantage of that the tool carrier through a coupling rod to common Pivoting are connected.
- Such training can pivot with only one hydraulic cylinder piston unit are effected, both at the same time swiveling tool carrier swiveled into the desired position become.
- the training is advantageously done in such a way that the tool carrier each with a hydraulic cylinder piston unit are connected, which at the Schräm- or Cutting roller and outside the swivel axis of the tool carrier is articulated, with particularly small hydraulic Cylinder-piston units as actuating cylinders found enough can be.
- FIG. 1 shows a view of an end wall area a cutting roller in the direction transverse to the axis of rotation the roller seen with the tool holder in the extended position and
- Figure 1 is a plan view of the end wall of the roller Tool carriers swung in, partially cut.
- a cutting roller 1 is shown, on the end faces 2 bearing eyes 3 for the pivotable articulation of tool carriers 4 and 5 are defined.
- the tool carrier 4 and 5 are pivotable about the pivot axes 6 and 7 and each carry cutting chisels, which are designated 8.
- the upper of the two pivotable tool carrier 4 carries Mouth 9, which is a hook-shaped locking member for one Locking bolt 10 represents, the axis 11 of the jaw opening of the mouth 9 arranged inclined to the tool carrier 4 is.
- the locking bolt is thus supported in the extended position 10 on a steep flank 12 of the mouth 9, whereby the reaction forces effective in the sense of expansion can be supported safely.
- a coupling rod 15 is provided which about a pivot axis 16 pivotally engages the tool carrier 5.
- the other end the coupling rod is pivotable about the pivot axis 17 a bearing eye 18 of the tool carrier 4 articulated.
- FIG. 2 thus shows a view of the end wall 2 of FIG Cutting roller 1 in the direction of arrow II of Figure 1, wherein however, the tool carriers 4 and 5 in their starting position were pivoted in, whereby the locking bolt 10 except Engagement reached and pivoted towards the edge of the cutting roller becomes.
