Definitions

  • the present invention relates to a trench cutter according to the preamble of claim 1 and a trench cutter according to the preamble of claim 10.
  • Trench wall milling machines are known in a variety of versions from the prior art.
  • a wide variety of drive methods can be used for the milling tools of such trench wall cutters, which are used to comminute the base material in the production of the base slot.
  • one or more motors are used for the rotary drive of several cutter wheels via appropriate gears.
  • gearboxes assigned to the respective milling wheels are used per trench wall cutter or per drive unit.
  • These gearboxes and other components such as wear plates mounted on the drive unit are affected by the usual milling wear and must therefore be regularly serviced or replaced. This means that not only the initial assembly of the drive unit is a relevant step, but also the repeated removal and installation necessary in the event of maintenance or wear.
  • the complete drive unit is usually assembled or disassembled to provide access to the gearboxes. This exchange process typically turns out to be cumbersome and time-consuming.
  • the present invention has for its object to provide a trench cutter with a drive unit, which can be assembled and disassembled quickly and easily.
  • this object is achieved by a trench cutter with the features of claim 1 and by a trench cutter with the features of claim 10.
  • the invention relates on the one hand to a trench wall cutter for producing vertical bottom slots, which can be connected to a carrier device, comprising a frame, a motor unit and a drive unit which can be detachably connected to the frame.
  • the drive unit comprises a carrier structure, at least one gear arranged on the carrier structure and at least one milling tool connected to the gear and drivable by the motor unit for comminuting soil material.
  • the motor unit can be detachably connected to the drive unit, the frame and the drive unit each having guide means which are designed in such a way that the drive unit enters the frame laterally with respect to a longitudinal axis of the frame, in particular when the connection to the motor unit is released - and can be pushed out of it.
  • Pushing the drive unit, which is separate from the motor unit, in and out laterally offers considerable advantages when carrying out maintenance work and enables components to be exchanged in just a few steps.
  • the motor unit which is not subject to wear to the same extent as the gearbox, can remain in the installed position in or on the frame during assembly or maintenance work, while only the drive unit has to be dismantled or assembled.
  • the assembly times are when installing and Expansion therefore significantly shorter than with conventional trench wall cutters.
  • the simplified assembly and disassembly process also increases safety in the workplace. Potential errors in the exchange process are minimized by the small scope and the simple design of the overall process.
  • the drive unit has a motor mount with which the motor unit can be detachably connected and which is preferably arranged on the top of the support structure.
  • the motor mount can have mechanical connections and connections for hydraulic and / or electrical lines. These can be designed as a quick coupling or multi-coupling.
  • the trench wall cutter can comprise a plurality of drive units, each with an associated motor unit.
  • the frame has a recess on at least one side, preferably on two opposite sides, through which the motor receptacle can be pushed when the drive unit is moved by means of the guide means.
  • the assembled motor protrudes into the frame of the trench cutter and can be moved relative to the frame after being separated from the motor unit and pushed through the recess (es).
  • the cutout therefore has geometric dimensions that exceed those of the motor mount.
  • the guide means of the frame and the drive unit are configured as chamfers, the beveled surfaces of which contact one another in the connected state.
  • the beveled surfaces When the drive unit is laterally displaced relative to the frame, the beveled surfaces thus slide past one another.
  • the guide means are preferably formed both on the frame and on the support structure.
  • the motor mount can be arranged between the guide means on the top of the support structure.
  • the frame has a recess on the underside into which a part, preferably an upper part, of the drive unit can be inserted, a detachable connection of the drive unit and frame relative to the frame being seen either by lateral insertion of the drive unit can be produced in the lateral recess or (with vertical alignment of the frame) from below to bring the drive unit into the lower recess.
  • the first assembly of the drive unit or an assembly after replacing or servicing the motor unit, preferably with the motor unit connected to the motor mount can be carried out relative to the frame from bottom to top by pushing it into the lower recess.
  • This is therefore dimensioned in particular so that the motor mount together with the motor unit connected to it can be inserted.
  • the drive unit can be installed and removed for assembly or maintenance purposes of the wear parts such as the gearbox and wear plates after the connection to the motor unit has been disconnected by moving the drive unit sideways with respect to the frame.
  • the guide means are arranged and designed such that when the drive unit is introduced into the lower recess of the frame, the drive unit is centered and finely positioned relative to the frame.
  • the guide means therefore have a double function. These are preferably designed as chamfers, with the chamfered surfaces of the chamfers formed on the frame pointing downward, so that when the drive unit is introduced from the bottom up, centering is automatically carried out by contacting and guiding the respective chamfered surfaces. This significantly simplifies and speeds up the paving process.
  • the drive unit can be introduced into the lower recess in a state in which the motor unit is connected to the motor mount.
  • the drive unit can be detachably connected to the lower end of the frame.
  • the motor unit can be detachably connected to the frame or to corresponding connections provided on the frame, wherein the connections can serve to produce a hydraulic and / or electrical supply to the motor unit.
  • the present invention further comprises a trench wall cutter for producing vertical bottom slots, which can be connected to a carrier device, comprising a frame, a motor unit and a drive unit, the drive unit having a carrier structure, at least one gear arranged on the carrier structure and at least one connected to the gear and milling tool drivable by the motor unit for comminuting soil material and wherein the frame and the drive unit have connecting means by means of which the frame and the drive unit can be releasably connected to one another are.
  • the motor unit can be releasably connected to the drive unit, the connection means being accessible from the outside, so that the connection between the drive unit and the frame can be established or released from the outside.
  • connection means which are easily accessible from the outside and which are preferably parts of a screw-nut connection, significantly simplify the assembly and disassembly of the drive unit on the frame. This results in an enormous saving of time and an increase in safety at the workplace compared to embodiments in which connecting elements have to be loosened or attached within the frame during disassembly or assembly.
  • the frame has indentations which allow access to the connecting means from the outside, the frame preferably being designed such that the parts of the connecting means which are accessible from the outside are located within the indentations and within the outer contour which is extended beyond the indentations of the frame are arranged.
  • indentations which are arranged in particular laterally, the parts of the connecting means that are accessible for establishing or releasing the connection, in particular the nuts and screw heads of the screw connections, do not protrude beyond the outer contour of the frame, which would be obtained without indentations, so that the space requirement or the external dimensions of the trench cutter do not increase.
  • the indentations are preferably arranged on the sides of the frame on which there are no recesses.
  • the present invention further comprises a trench wall cutter for producing vertical bottom slots, which can be connected to a carrier device, comprising a frame, a motor unit and a drive unit, the drive unit having a carrier structure, at least one arranged on the carrier structure Gearbox and at least one milling tool connected to the gearbox and drivable by the motor unit for comminuting soil material, the frame and the drive unit each having connecting means by means of which the frame and the drive unit can be releasably connected to one another, the motor unit being releasably connectable to the drive unit
