Definitions

  • the invention relates to a trench wall cutter with at least one bearing plate, a central drive shaft, which is arranged in the bearing plate, at least two cutting wheel drives, which are each arranged on one side of the bearing plate, and at least two cutting wheels, which are each mounted on a cutting wheel drive and are rotated by it are drivable, according to the preamble of claim 1.
  • the invention also relates to a method for changing a cutting width of a trench wall cutter, with existing first cutting wheels having a first cutting wheel width being changed and being replaced by second cutting wheels having a second cutting wheel width which is different from the first cutting wheel width, according to the preamble of claim 14.
  • a generic trench wall cutter with an end shield and a cutter wheel drive arranged on the side with a cutter wheel is known, for example, from EP 1 666 671 B1 known.
  • the cutting wheel drive is designed as a gear.
  • a drive torque from a drive motor mounted on the cutter frame is transmitted via a central drive shaft in the bearing plate to transversely directed drive shafts, which divide the drive torque between the two cutter wheel drives.
  • the cutting wheel drives are usually designed as reduction gears.
  • the cutting wheel drives protrude into a hollow hub area of the drum-shaped cutting wheels, which are mounted on the cutting wheel drives via a rotary bearing arrangement.
  • the milling wheels are designed in such a way that they reach up to the end shield for effective milling.
  • the axial length of the milling wheels determines the width of the milling slot.
  • the width of the milling slot results from twice the length of the milling wheels plus the width of the end shield.
  • Diaphragm wall cutters are used to create diaphragm walls or cut-off walls in the ground, with the cut trench formed in the ground being filled with a hardening concrete or sealing compound.
  • a typical slot width is about 1 meter, although depending on the respective requirements, slot wall widths of up to 2 meters and more must be created.
  • Another generic trench wall cutter is from the EP 1 637 794 B1 out.
  • the invention is based on the object of specifying a trench wall cutter and a method with which different trench widths can be produced particularly efficiently.
  • the trench wall cutter according to the invention is characterized in that the cutting wheel drives are each designed as a detachable cutting wheel drive module and that an adapter module is arranged between the bearing plate and each cutting wheel drive module, which can be removed and exchanged to adapt to different cutting wheel widths.
  • a basic idea of the invention is to construct the trench wall cutter in a modular manner with regard to the cutting wheel drive and its holder. If the diaphragm wall width is changed, not only the cutting wheels with a changed diaphragm width are exchanged. Rather, it is provided according to the invention to also change and adjust the position of the cutting wheel drive when changing the cutting width of a cutting wheel. According to the invention, this is achieved on the one hand in that each cutting wheel drive is designed as a cutting wheel drive module which can be easily assembled and disassembled as a unit.
  • a cutting wheel drive module within the meaning of the invention can be a drive motor flanged to the bearing plate with or without a gear or just a gear which is driven via a drive shaft in the bearing plate.
  • an adapter module is arranged between the bearing plate and the cutting wheel drive module, which can be easily changed and adjusted when replacing cutting wheels with a different cutting width.
  • the adapter module can each have a correspondingly adapted axial width, so that the existing cutting wheel drive module is preferably further loaded centrally, ie the point of application of the forces caused by the cutting wheels act approximately centrally on the cutting wheel drive and a corresponding pivot bearing arrangement. In this way, undesired transverse forces and tilting moments on the cutting wheel drive can be largely avoided, so that maintenance costs are reduced and a long service life of the motor and/or the gear is ensured.
  • the same milling wheel drive modules can thus be used for different milling widths with essentially the same favorable load.
  • the formation of the cutting wheel drive modules and the rotary bearing arrangements can be the same for both sides of the bearing plate, so that only a few components are required for a large number of trench wall cutters with different trench widths. If necessary, the cutting wheel drive modules can also be exchanged and/or changed in a simple manner.
  • a preferred embodiment of the invention is that the cutting wheel drive module has a sleeve-shaped housing on which a drum-shaped cutting wheel is rotatably mounted via a rotary bearing arrangement.
  • the rotary bearing arrangement preferably has roller bearings, which are preferably positioned in an O arrangement on the outer circumference of the sleeve-shaped housing. With this arrangement, long service lives of the bearings can be achieved.
  • the rotary bearing can be arranged on an outside or on an inside of a housing wall.
  • an axial center of the rotary bearing arrangement is aligned with an axial center of the cutting wheels.
  • the position of the milling wheels on the milling wheel drives can be selected in such a way that the inner edge of the milling wheels must reach up to the end shield for effective milling. With an increase in the width of the cutting wheel, a center of the cutting wheel is thus shifted further outwards.
  • the cutting wheel drive module can be tracked to the center shift.
  • the enlargement of the adapter module can correspond to about half the length of the cutting wheel extension.
  • a damping element for damping torque shocks can be arranged between the output shaft and the cutting wheel.
  • the adapter module is ring-shaped with a central passage for a shaft to pass through.
  • the adapter module can be solid.
  • the adapter module can be easily releasably connected to the cutting wheel drive module on the one hand and to the end shield on the other hand via screw connections.
  • the adapter module is box-shaped with an inner cavity.
  • an inner cavity In particular at By setting larger slot widths, a relatively light construction can be achieved.
  • the formation of a closed inner cavity means that the installation of the adapter module does not result in an excessive additional need for transmission oil.
  • the adapter module is preferably constructed from a steel material and, in particular, is welded, although light metal materials can also be used.
  • a particularly preferred embodiment is that the box-shaped adapter module has two side plates, an axially circumferential peripheral wall and a sleeve for forming a central passage.
  • a hollow adapter module with an inner closed cavity can thus be produced in a simple manner, in particular by welding.
  • the adapter module has at least one additional through-channel for oil to pass through. This means that oil does not have to pass solely through the center passage of the adapter module between the bearing plate and the cutting wheel drive module, particularly if this has a gear.
  • An oil channel is preferably arranged in a lower area of the adapter module and/or in an upper area.
  • the cutting wheel drive modules have a gear which can be driven via a central drive shaft in the end shield.
  • a reduction gear is formed in the housing of the cutting wheel drive module.
  • a further advantageous embodiment of the invention is that the cutting wheel drive module has a drive motor arranged on the end shield with or without a gear.
  • the cutting wheel drive module can in particular be designed as a direct drive for directly driving the cutting wheel attached to it.
  • the drive type of this drive is basically arbitrary, with an electric motor in particular is compact and easy to assemble.
  • the direct drive can be provided with or without a gear stage, in particular a reduction gear.
  • the milling drive module it is advantageous for the milling drive module to have an input shaft on the side of the end shield and an axially opposite output shaft, which is detachably connected to the associated milling wheel.
  • the cutting wheel drive module thus has a defined input element and a defined output element for torque transmission.
  • An input shaft or an output shaft within the meaning of the invention can also be understood to mean a ring gear or a toothed wheel without a pronounced longitudinal extension.
  • the input shaft and/or the output shaft preferably have an easily detachable, torque-transmitting connection, such as an axial spline connection. This allows easy assembly and disassembly of the milling wheel drive module.
  • an exchangeable adapter shaft is detachably arranged between the central drive shaft and the respective cutting wheel drive module.
  • the length of the detachable adapter shaft depends on the width of the adapter module.
  • a good torque transmission can continue to be achieved from the central drive shaft in the end shield to the input shaft of the cutting wheel drive module.
  • a bevel gear stage can be arranged in the bearing plate at the lower end of the central drive shaft, with which the torque is transmitted from the essentially vertically oriented central drive shaft to the essentially horizontally oriented distribution shafts.
  • a further advantageous embodiment of the invention lies in the fact that it has a milling cutter frame, on the underside of which at least one bearing plate with the milling wheel drive modules is arranged.
  • a milling cutter frame on the underside of which at least one bearing plate with the milling wheel drive modules is arranged.
  • two side-by-side end shields are arranged on the underside of the milling machine frame. In this way, two pairs of milling wheels can be arranged compactly at the lower end of the milling machine frame.
  • a drive to be mounted on the milling cutter frame, by means of which the central drive shaft can be driven in rotation.
  • a total of several central drive shafts can also be provided, in particular if several end shields are attached to the milling machine frame.
  • a hydraulic motor is provided as the drive for a high torque.
  • a trench wall cutter 10 has a cutter frame 12, only a lower part of the cutter frame 12 being shown in the figure.
  • One or preferably two plate-shaped bearing plates 14 are attached to an underside of the milling cutter frame 12, on both sides of which a cutting wheel 20 with outer cutting teeth 24 is mounted so that it can be driven in rotation.
  • a drive shaft 16 is indicated schematically with its drive axle, which is driven in rotation by a drive motor, not shown, on the milling cutter frame 12 .
  • the drive shaft 16 extends within an interior space of the hollow bearing plate 14.
  • a bevel gear (not shown)
  • the drive torque from the drive shaft 16, which is directed essentially vertically during operation, is applied approximately at right angles to the two laterally directed adapter shafts 70 for driving the cutting wheels 20 distributed.
  • the adapter shafts 70 also represent an input for a gearbox 31 of a cutting wheel drive module 30.
  • a drum-like cutting wheel drive module 30 is detachably attached to each side of the bearing plate 14, on each of which a cutting wheel 20 is rotatably mounted via a pivot bearing arrangement 40 with roller bearings 42.
  • each cutting wheel drive module 30 has a drum-shaped housing 32, on the inside of which a ring gear 33 is formed.
  • a planetary carrier 36 is rotatably mounted about an axis of rotation 21 of the cutting wheels 20 via the pivot bearing arrangement 40 .
  • a plurality of planet gears 34 are rotatably mounted on the planet carrier 36, which on the one hand mesh with a central drive pinion on the adapter shaft 70 and on the other hand with the ring gear 33 with an internal toothing, so that the planetary carrier 36 can be rotated about the axis of rotation 21 as a reduction step.
  • a cylindrical base body 22 of the cutting wheel 20 is attached in a rotationally fixed manner to an outer side of the planetary carrier 36 via an annular elastic damping element 28 .
  • the rotary drive arrangement 40 is located approximately in an axial center plane which is perpendicular to the axis of rotation 21 and centered on the axial width of each cutting wheel 20 .
  • the associated cutting wheel 20 is thus attached to the planetary carrier 36 .
  • annular adapter module 50 When mounting a cutting wheel 20 with a different axial wheel width, an annular adapter module 50 can be changed, which is arranged between the bearing plate 14 and the respective cutting wheel drive module 30 .
  • each adapter module 50 is formed from a first side plate 52, which is detachably flanged to the associated side of the bearing plate 14, and a second side plate 54, the two side plates 52, 54 having an annular outer peripheral wall 56 and a central sleeve 58 are preferably formed by welding to form a central passage 60 for the adapter shaft 70.
  • a central annular cavity 62 is thereby formed in the adapter module 50, as a result of which a relatively light construction and a small oil holding volume in the central passage 60 are achieved.
  • the cutting wheel drive module 30 is preferably detachably fastened to the second side plate 54 via screw connections.
  • An interior of the end shield 14 and an interior of the housing 32 are filled with oil and are in fluid communication with one another via the central passage 60 and additional passage channels 64 in or along the peripheral wall 56 of the respective adapter module 50 .
  • the common gear space formed in this way is at least partially filled with gear oil.
  • the existing cutting wheel 20 is removed along with the respective cutting wheel drive module 30 and the associated adapter module 50 are detached from the end shield 40.
  • a suitable, larger adapter module 50 is then inserted and the existing cutting wheel drive module 30 is again attached to the bearing plate 14 together with the adapter module 50 .
  • the modified cutting wheel 20 can be mounted on the cutting wheel drive module 30 .
