Definitions
- the invention relates to a cutting machine with rotatably mounted cutting or cutting tools, with a loading ramp and a conveyor running in the direction of the face for receiving and removing the cut or cut material, in which the cutting or cutting tools on one in the machine longitudinal direction slidable sliding guides are mounted.
- DE-Al 40 18 154 describes a cutting machine in which the entire machine frame of a tunneling machine is designed to be displaceable relative to the crawler track.
- the guide devices are arranged on both sides of the crawler chassis extending in the machine longitudinal direction, these guide elements, which are connected to the crawler track, being encompassed.
- the entire machine frame is shifted relative to the stationary crawler chassis in the machine longitudinal direction.
- Anchoring near the face is still relatively limited.
- the invention now aims to provide a Drive machine of the type mentioned to the extent that, in addition to a particularly low design for use in low seams, the possibility is also created to use anchor drilling and setting devices directly behind a cutting tool, the whole with such anchor drilling and setting devices required anchor profile can be safely introduced in a simple manner.
- a parallel cutting operation should not be impaired in any way, and adequate support of the cutting forces should also be reliably ensured during the anchoring.
- the cutting machine according to the invention of the type mentioned essentially consists in the fact that the guides of tubes or rods connected to a machine frame in the area of the crawler tracks, preferably within the crawler chassis frame, are formed so that the slide of longitudinal bars and a cross member for the storage of the cutting or cutting tools is formed and that the machine frame is designed, at least in its front area adjacent to the cross member, as a box profile, in the clear width of which the discharge conveyor is displaceably guided in the machine longitudinal direction.
- a machine frame designed as a box profile is provided, which has guides in the area of the crawler tracks, provides a particularly stable machine frame, which frame can accommodate the conveyor for the removal of the cut or obtained material with an extremely low overall height of the entire facility.
- the slide Because the slide is now slidably guided on the tubes or rods, the slide can also be arranged relatively low, and since the slide is formed by longitudinal spars and an end cross member, the cutting tools are fixed on the slide without increasing the overall height of the entire machine. Behind this cross member, which can be moved together with the slide in the longitudinal direction of the machine, there is now sufficient space on the machine frame which anchor drilling and setting devices can be used for flexible use for anchoring over the entire required anchor profile.
- the machine frame which carries the guides for the slide in the plane of the caterpillars of the caterpillar undercarriage, can advantageously only have corresponding upward-facing assembly devices at its front end facing the cross member, such as a mounting plate or mounting bars for the arrangement of anchor drilling and -Setting devices, so that these anchor drilling and setting devices can also be articulated low on the machine frame and supported, so that a large swivel range and thus a large working area is available for the anchor drilling and setting devices.
- this is particularly important because anchors with lengths of several meters can be used for safe anchoring, which, with correspondingly low articulation of the anchor drilling and setting devices on the machine frame, can be safely inserted into the anchor drilling and - without complex manipulation.
- Setting devices can be introduced and thus be placed.
- the design according to the invention is advantageously made such that the slide and in particular the longitudinal spars connected to the crossmember have or have tabs which at least partially encompass the guides and can be displaced in the machine longitudinal direction via at least one hydraulic cylinder-piston unit supported on the machine frame.
- the displaceable slide and in particular the longitudinal spars, which are connected to the cross member can thus also be arranged essentially m on the plane of the crawler track, whereby the overall height is further reduced.
- the sled can be moved essentially on the plane of the crawler track due to its construction of longitudinal spars and crossbeams, only in the area near the face the corresponding free space for the removal of the cut Material must be provided.
- This is particularly easy to achieve by appropriately designing the end crossmember, the design advantageously being such that the crossmember of the displaceable slide engages around the box profile of the machine frame in a portal-like manner.
- the lower area of the crossmember is not required for the articulation of cutting tools, so that such a portal-like construction creates additional space with a low overall height, the cut material being able to be discharged safely.
- Such a portal-like design of the crossmember or a portal connected to the crossmember spans a plane which, in the side view, results in an L-shaped design of the slide, with corresponding space for drive and control units and energy supply devices in the area above the machine frame Cutting machine remains with the lowest overall height.
- the design according to the invention is such that the mounting plate or the mounting spars extends (extend) essentially parallel to the portal-like cross member of the slide and, in the side view, encloses an angle less than or equal to 90 ° with the machine longitudinal axis in the direction of the working face (lock in) .
- Such an inclination of the mounting plate or the mounting spars enables anchors to be placed close to the working face without affecting the cutting or cutting operation.
- a particularly stable support of the machine during the cutting operation and thus a further improvement of the anchor drilling and setting operation can be achieved in that the machine frame has support brackets for support rams outside the crawler track.
- the support is thus wide, so that a particularly stable construction with a low overall height is achieved.
- the training is meet that the anchor drilling and setting devices are pivotally connected to the mounting plate or the mounting spars about a pivot axis running essentially in the longitudinal direction of the machine.
- the advantages of the low construction of the entire machine are optimally used here, since the swivel axis for the anchor drilling and setting device can be arranged near the sole, so that even long anchors can be safely inserted and manipulated in the anchor drilling and setting devices.
- a particularly efficient anchor drilling and setting operation can be achieved if at least two anchor drilling and setting devices arranged in a V-shape on a common support are pivotally connected to the mounting plate or the mounting rails of the machine frame, the common pivot axis being at the level of a lower pivot axis multi-part cantilever arm for cutting tools on the portal-like cross member of the carriage or below this pivot axis.
- the entire required anchor profile can be introduced economically, the support of the machine frame being additionally improved by the support rams arranged on the support brackets.
- the design is advantageously made such that the pivot axes of the cantilever arms are arranged substantially parallel to the longitudinal axis of the machine and the pivot axis of the anchor drilling and setting device is inclined downward to the face.
- the removal can be optimally adapted to the respective requirements in that the loading ramp is pivotally connected in the vertical direction to the conveyor which can be driven in the longitudinal direction of the machine, the conveyor being able to be accommodated in the box profile of the machine frame rigidly connected to the crawler tracks with a very low overall height .
- the loading ramp is pivotally connected in the vertical direction to the conveyor which can be driven in the longitudinal direction of the machine, the conveyor being able to be accommodated in the box profile of the machine frame rigidly connected to the crawler tracks with a very low overall height .
- FIG. 1 shows a schematic side view of the machine according to the invention
- FIG. 2 shows a view in the direction of arrow II-II, partly in section
- FIG. 3 shows a view similar to FIG. 2 through a modified design of the displaceable slide.
- Fig. 1 denotes a crawler track of a cutting machine 2.
- the machine frame is designed as a box section 3, in which a conveyor, the rear end of which is indicated schematically by 4, is mounted so as to be displaceable in the direction of the double arrow 5.
- This box section 3 which is stationary relative to the crawler chassis, forms a torsion-resistant machine frame at the rear end of which is articulated on a bracket 6 a hydraulic cylinder piston unit 7, which acts at 8 on the displaceable slide.
- the displaceable slide comprises a cross-shaped cross member 9 which is connected to longitudinal members or longitudinal bars 10 running in the longitudinal direction of the machine. These longitudinal spars 10 are in turn connected to brackets 11 which grip guide tubes or rods 12.
- the guide tubes or rods 12 are each rigidly connected in the plane of the crawler chassis 1 to the machine frame having the box section 3.
- the cross member 9, together with the longitudinal spars 10 running in the longitudinal direction of the machine is displaced in the direction of the double arrow 5 through the tabs 11 on the tubes or rods 12, the machine frame itself being connected to the crawler chassis 1 so that it cannot move is.
- a mounting plate or mounting spars 13 is now arranged, on which anchor drilling and setting devices 1-4 are fixed pivotably about an axis 26.
- a first cantilever arm 16 is articulated on the cross-shaped cross member 9, which is pivotable about a first pivot axis 15, on which a pivotable arm about a second pivot axis 17 further cantilever arm part 18 is pivoted.
- the cutting tool is indicated schematically at 19 and is formed by a cutting head. In principle, any short dismantling tools can be fixed on the cross member.
- the mounting plate 13 is inclined towards the face so that the pivot axis 26 of the anchor drilling and setting devices 14 also slopes downward towards the face 20, whereby anchors can be introduced closer to the face.
- FIGS. 2 and 3 The construction is described in more detail in FIGS. 2 and 3 on the basis of different slide constructions.
- the portal-like cross member 9 is connected to four bars 10 running in the machine longitudinal direction.
- the machine frame designed as a box section 3 carries the tubes or rods 12 which are encompassed by the tabs 11 of the slide.
- support brackets 21 for support rams 22 are arranged, by means of which the ridge 23 and the use of corresponding ridge caps 24 are supported. 2 and 3 it can be seen that in each case two anchor drilling and setting devices 14 are mounted in a V-shape on a common support, the common pivot axis again being designated by 26.
- the slide in addition to the cross member 9, which surrounds the box section 3 in a portal-like manner, the slide has only two frame spars 10, the displacement drive being indicated schematically by 25.
- This displacement drive 25 corresponds to the hydraulic cylinder piston unit 7 in FIG. 1. - o -
