Definitions

  • the invention relates to a trench cutter with at least two pairs of cutting wheels, which are rotatable about a first axis of rotation and a second axis of rotation, wherein the two axes of rotation are offset from each other.
  • the two pairs of cutting wheels are each set in rotation by a separate drive motor via a corresponding gear arrangement.
  • Another generic trench cutter is from the EP-A-0 811 724 known.
  • the milling frame suspended on a device has an anchoring part with positioning and anchoring skids and a lifting tool which can be extended by hydraulic cylinders.
  • At the lower end of the support tool are mounted on mutually offset, driven by a respective hydraulic motor axes Fräsradpare.
  • the cutting wheels are lying each in one plane and rotate in the opposite direction.
  • a suction generated by a hydraulic pump the decomposition material is sucked in halfway and in the middle between the staggered cutting wheels and transported via hoses upwards.
  • a hammer drill for making slot holes using a jet aspirator will be described.
  • the device has the same length, counter-driven rod assemblies, which are combined by a provided with wall guide elements bridge connection to a unit.
  • Each drill string is assigned a drill bit and each in the strand inside the cuttings are promoted high.
  • a drive motor arranged on the bridge drives a transmission which distributes drive torque to a plurality of drill bits.
  • the invention has for its object to provide a trench cutter, which ensures a reliable milling operation in a simple and compact structure.
  • the trench wall cutter according to the invention is characterized in that a single drive motor is provided which via a gear arrangement which drives at least two cutting wheels or pairs of cutting wheels together.
  • a common drive and a common gear arrangement also allow forced synchronization of the cutting wheels. This allows the transverse to the axis of rotation juxtaposed milling wheels arranged closer together. This results in a particularly compact trench wall cutter with good material removal, in which the risk of getting stuck within the slot is significantly reduced.
  • gear arrangement has a sun gear, which is arranged substantially centrally between the two mutually offset axes of rotation. This results in a symmetrical torque introduction, which allows a particularly uniform torque distribution.
  • a particular compact gear arrangement according to the invention is achieved in that the two pairs of cutting wheels each have a common drive train, which are driven by the sun gear.
  • a particularly good torque distribution in a compact design is achieved according to the invention in that the drive trains are arranged at an acute angle to the axis of the sun gear.
  • the drive trains form with the sun gear an arrangement in the form of an inverted Y, wherein the drive trains are arranged above the axes of rotation of the cutting wheels and directed upward.
  • the acute angle is preferably between 15 ° and 60 °, in particular 45 °.
  • the drive trains are arranged approximately at a right angle to each other.
  • the drive trains each have at least one transmission gear. Under gear transmission is understood, of course, a reduction. It can be done directly on the cutting wheels so a desired torque conversion.
  • the drive trains in the arrangement of Fräsradcruen also each have a distribution gear, which distributes the torque of the drive train in equal parts on the cutting wheels along the same axis of rotation.
  • radially projecting cutting teeth are provided on the cutting wheels or cutting wheel pairs, which are arranged intermeshing in operation. Due to the achievable with the invention forced synchronization of juxtaposed cutting wheels they can be arranged so close to each other that the cutting teeth mesh with each other safely. In this way, a uniformly high removal rate can be achieved over the entire milling cross section.
  • a particularly good and maintenance-friendly embodiment of the invention is given by the fact that the drive motor and the gear arrangement are arranged in a milling housing.
  • the trench wall cutter is attached to a telescopic linkage and that the thickness of the milling housing in the direction of the axes of rotation is less than or equal to the maximum diameter of the telescopic linkage.
  • the compact trench cutter according to the invention can be performed by a telescopic linkage. Due to the compact design of the milling housing according to the invention, which does not protrude beyond the maximum diameter of the telescopic linkage in the direction of the axes of rotation, the risk of jamming of the trench wall cutter in the slot is drastically reduced.
  • a main drive shaft is arranged between the drive motor and the sun gear.
  • the main drive shaft can each have at its two ends in each case curved toothings, which are arranged in meshing manner in corresponding toothed sleeves of the drive motor or of the sun gear.
  • a trench wall cutter 10 according to the invention shows two cutting wheels 12, 14, on whose outer circumference a plurality of cutting teeth 20 are arranged.
  • the cutting wheels 12, 13 each belong to a cutting wheel pair, wherein the rear cutting wheel is not shown.
  • the left-side cutting wheel 12 of a pair of cutting wheels rotates about a first axis of rotation 16, while the right-side cutting wheel 14 of the other pair of cutting wheels rotates about a second axis of rotation 18.
  • the two axes of rotation 16, 18 are offset in a transverse direction to each other by a predetermined distance.
  • the left-side cutting wheel 12 is driven in the clockwise direction, while the right-side cutting wheel 14 is driven in the counterclockwise direction.
  • the drive torque via a gear assembly 30 to the cutting wheels 12, 14 and their Fräsradforme transmitted.
  • the torque is transmitted via a partially shown main drive shaft 36 to a sun gear 32.
  • the main drive shaft 36 has for this purpose at its lower end a curved toothing 37, which is arranged in a corresponding toothed sleeve at the upper end of the sun gear 32.
  • the sun gear 32 has an axis 33 which is approximately perpendicular to the axes of rotation 16, 18 of the cutting wheels 12, 14 directed and arranged centrally thereto.
  • the torque is transmitted in a combing connection via the plate gears 42, 52 on the drive lines 40, 50 for the cutting wheels 12, 14 and their Fräsradpare.
  • the drive trains 40, 50 each have gear ratios, not shown, which reduce the speed of the sun gear 32 and thus increase the torque for the cutting wheels 12, 14 to a desired value.
  • the axes of the drive trains 40, 50 are arranged approximately at right angles to each other and form with the axis 33 of the sun gear 32 an upside-down Y-arrangement.
