DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] FIG. 1 shows a machine housing 2 of a roller crusher as an exemplary embodiment of a comminuting machine of a comminuting plant according to the invention. It can be seen that two displacement apparatus 1 can be arranged in the housing wall 3. The rear displacement apparatus is shown in the mounted state and the front displacement apparatus is shown as an exploded diagram in a dismantled state. Two further displacement apparatus are arranged on the opposite housing wall but are covered and therefore not visible in FIG. 1.

[0033] FIGS. 2-6 show details of the housing wall 3 of FIG. 1 in a region of the displacement apparatus 1 in the mounted state. The housing wall 3 is part of the machine housing and has a structure of reinforcing ribs 14. The reinforcing ribs 14 are welded to other steel plates for reinforcement and thus help to provide the necessary mechanical strength of the housing wall 3. In the example shown, the displacement apparatus 1 has a lifting apparatus, which is mainly the hydraulic cylinder 4. The lifting apparatus can push a support element 16, which can be seen in FIGS. 5 and 6, of the displacement apparatus 1 downwards out of the housing wall 3 and in the process lift the comminuting machine in the region of the displacement apparatus 1. In the exemplary embodiment shown, the use of the hydraulic cylinder 4 is intended only when the comminuting machine is stopped at a location, to push the support element 16 far enough away from the hydraulic cylinder 4 to open a pressure element introduction opening 6 for introducing or removing a pressure element 5. During a displacement process, however, the hydraulic cylinder 4 is preferably relieved and the load in the region of the displacement apparatus 1 is directed via the support element 16 and the pressure element 5 into the reinforcing rib 14 situated above the pressure element 5 or initially into a threaded ring 20 serving to fasten the hydraulic cylinder 4. The pressure element 5 directs the effective forces as a pressure plate over a large area into the housing wall 3 so that no stress peaks and damage can occur in this region during the process of displacing the comminuting machine. Below the pressure element 5, the design element of a wall or reinforcing rib 15 shaped as an open cylinder is shown, which acts as a support element guide for the cylindrical support element 16 behind it.

[0034] In the exemplary embodiment shown, the comminuting plant includes the load-bearing structure 10, a section of which is shown, the rails 7 being laid on the load-bearing structure 10 in two directions, specifically in an X direction and a Y direction. The comminuting machine can be displaced on its displacement apparatus 1 on the load-bearing structure 10 in a substantially horizontal plane. In the displacement position shown in FIG. 2, the support element 16 and the comminuting machine thereon stand on a wheel 17, which can be seen in FIGS. 5 and 6, and there is a possibility of displacement in the Y direction. Rail guides 8 are arranged axially next to the wheel 17 and fit over the rail 8 in a forked manner in FIG. 2, preventing movement in the X direction and only allowing movement in the Y direction. The cylindrical support element 16 of the displacement apparatus shown is rotatable about the Z axis and can be locked with a locking element 9 at two angles, specifically at 0 for displacement in the X direction and at 90 for movement in the Y direction. In the exemplary embodiment shown, the locking element 9 is a cuboid bar, which is secured in its inserted position against accidentally sliding out by means of the securing element, which can also be seen. The locking element 9 can be seen in its entirety in the pulled-out position in FIG. 4.

[0035] The load-bearing structure 10 has a turntable 11 with a rail segment 12 formed thereon, which is rotatable about the Z axis about a central, vertically oriented pivot. The turntable 11 can be locked either in the X orientation or in the Y orientation with the two visible bolts. In the middle of the rail segment 12 shown, there is a cylindrical recess 13, in which the wheel 17 is provided during simultaneous rotation of the turntable 11 and the support element 16.

[0036] FIG. 3 shows a somewhat smaller detail of the displacement apparatus 1, in a standing position in which the pressure element 5 is kept fastened on its rest and the hydraulic cylinder 4 is retracted, so that the comminuting machine stands directly or indirectly on the load-bearing structure 10 and thus e.g. can be used productively to crush rock or can be maintained. In FIG. 4, a pressure element receiving opening 6 can be seen, since the pressure element 5 has been manually removed. Via the opening of the pressure element receiving opening 6 there is a view of the cylindrical support element 16, which has an annular collar at the top on which the pressure element 5 is placed. Here, the pressure element 5 has been taken out, stored and secured by means of screw-fastenings at a storage location inside the housing wall 3, as can be seen in FIG. 4. The inner raised cylindrical edge inside the annular collar serves as a stop for the horseshoe-shaped pressure element 5 when the latter is inserted into the pressure element receiving opening 6. The pressure element 5 has a retaining plate and a handle. In FIGS. 3 and 4, shims (not shown) are arranged between the load-bearing structure 10 and the housing wall 3, so that the weight of the comminuting machine acts on the shims and not on the displacement apparatus 1.

[0037] FIG. 4 shows the displacement apparatus 1 during conversion from the Y orientation of the cylindrical support element 16 as shown in FIGS. 2 and 6 to the X orientation shown in FIG. 5. In FIGS. 5 and 6, the housing wall 3 is shown partially open to allow a view of internal parts of the displacement apparatus 1. The cylindrical support element 16 is a perforated cylinder with a cuboid cut-out 18 for receiving the wheel 17. Owing to the cuboid cut-out 18, the support element in the exemplary embodiment shown has the form of a fork which, at the same time, acts as a guide for the wheel 17 and also forms the forked rail guide 8. In other exemplary embodiments which are not shown, the rail guide is implemented differently, for example by a double-flange on the wheel (17).

[0038] In the exemplary embodiment shown, the wheel 17 and the locking element 9 have substantially the same width as the cuboid cut-out 18, so that the cut-out 18 can be used as a guide for the wheel 17 during displacement and as a guide for the locking element 9 when the lifting apparatus is raised and lowered. A cylindrical and cuboid cut-out 19 in the support element 16 serves for the introduction of a wheel axis in its cylindrical part and as a guide groove for the locking element 9 in its cuboid part with height adjustment of the support element 16 and simultaneously locked angular position. In the depictions of FIGS. 4 and 5, the locking element 9 is outside its guide in the displacement apparatus 1, so that the cylindrical support element 16 can be rotated in its support element guide formed from reinforcing ribs 15 shaped as open cylinders. A key 21 which is used for manually performing this rotation and has pins for engagement in corresponding holes in the collar of the support element 16 is likewise shown. During this rotation, the forked rail guide 8 fits over the rail segment 12 of the turntable 11, so that the angle of the previously released turntable 11 is set at the same time as the angle of the displacement apparatus 1 and of the support element 16.

[0039] After rotation, the angular position of the support element 16 is locked with the locking element 9 and the angular position of the turntable 11 is locked with the bolt provided for this purpose. Thanks to its angular adjustability, the displacement apparatus 1 shown can be used universally and efficiently for movements both in the X direction and in the Y direction. Therefore, multi-stage displacement processes can be carried out quickly and safely in a sequence of different directions. The presented displacement apparatus thus helps to provide a high degree of availability of the comminuting plant according to the invention.
