Definitions

  • the invention relates to a trench cutter for producing a trench wall in the floor according to the preamble of independent claim 1.
  • DE-A-3 007 457 shows a drive for a bucket wheel mounted on the bucket wheel arm of a bucket wheel excavator with a planetary gear inside the bucket wheel body.
  • the invention has for its object to provide a generic trench wall cutter, in which a particularly large torque is available on the cutting wheels for a given power of the drive motor, and in which at the same time the cutting wheels have a very high effective cutting width in relation to the entire slot width.
  • the inventive arrangement of the drive motor on the milling frame makes it possible for the space available in the milling wheels to be used exclusively for generating a very high torque.
  • the weight of the drive motor contributes to the generation of the high, required contact pressure, which is necessary for propelling the trench cutter in a hard floor.
  • the high torque per cutting tooth and a high weight for the contact pressure can be achieved on the one hand, particularly in the case of concrete or rocky floors.
  • a sufficient number of cutting teeth can be provided, which is necessary so that the milled material has a correspondingly small grain size, so that it is suitable for suction.
  • the gear device which connects the drive motor to the milling gears, is at least partially arranged in recesses in the end shield. This makes it possible to transmit the torque from the drive motor to the cutting wheel gear in an extremely space-saving manner.
  • the initially low torque delivered by the gear mechanism is converted into a very high torque in the cutting wheel gear by reducing the speed (up to approx. 20 revolutions per minute) and simultaneously increasing the effective lever arm.
  • the cutting wheel gear is designed as a multi-stage planetary gear.
  • the drive motor can be designed as an electric motor or as a hydraulic motor, and in both cases the milling drums can be replaced without having to open hydraulic lines.
  • the gear device arranged between the drive motor and the milling gears can be designed as a bevel gear set with a transmission shaft.
  • a constructive measure all that is required is that in the Bore plate is drilled, which may also have a small diameter, since the drive shaft is also dimensioned relatively small, since the input torque to be transmitted by the drive motor is small.
  • the bevel gear it is also possible to transfer the input torque from the drive motor to the cutter gear via a chain gear with a chain and two sprockets.
  • the gears are guided vertically between the drive motor and the axis of rotation of the cutting wheels, since on the one hand the weight of the motor is fully used for the contact pressure can be and on the other hand the torque is given to the milling gear in the shortest possible way.
  • the bearing plate can be made particularly thin in its vertically standing, flat section, with the result that the effective width of the cutting wheels can be very large in relation to the entire slot width .
  • the end shield is also advantageously designed so that its lower edge ends at a distance above the lower edge of the cutting wheels.
  • a drive motor and a gear device are provided separately for each cutter wheel gear.
  • the sections of the gear mechanism extending beyond the end shield can be encapsulated with a housing, so that on the one hand the gear is protected against external influences and on the other hand the operating personnel cannot get into rotating parts.
  • the gear devices arranged inside the end shield can advantageously also be arranged in such a way that they run essentially V-shaped in the end shield plane and essentially parallel and at a distance from one another perpendicular to the end shield plane. This means that each milling gear can be supplied with the torque required to drive it separately.
  • Each planetary gear of the two cutter wheels arranged parallel to the end shield is driven separately, but it is possible both in the case of the V-shaped arrangement of the gear devices and in the case of the vertical arrangement of a single bevel gear or chain gear to drive the two cutter wheels of a cutter wheel set.
  • the two cutting wheels of a cutting wheel set are driven via a single shaft, the cutting wheels rotating in the same direction.
  • the trench wall cutter according to the invention has a tooth coupling, which is arranged between the drive motor and the transmission shaft of a bevel gear, and enables the milling drums to be changed quickly and easily.
  • the trench wall cutter 1 consists essentially of a support frame 5 held by a support cable 3, to which a suction device with a pump 7 is attached.
  • the drive motors 9 for the cutter wheels 11 are attached to the cutter frame 5.
  • Two bearing plates 13, in which the milling wheels 11 are rotatably received, are also firmly connected to the milling frame 5.
  • the trench wall cutter 1 is moved forward according to the arrow 15 shown.
  • the diaphragm wall milling machine 1 shown only the front milling wheels 11 of the two milling wheels of the two milling wheel sets 10 arranged one behind the other can be seen in the front view shown.
  • the rear milling wheels in each case, like the front milling wheels 11 shown, run parallel to the end shield 13.
  • the two cutting wheel sets 10 rotate in opposite directions, as indicated by the two arrows in FIG. 1, and thus feed the milled material to the suction device with pump 7.
  • a shaft 17 of a bevel gear 19 leads vertically downward from the drive motor 9 arranged fixedly in the milling frame. From the bevel gear 19, the torque is transmitted, for example, to a sun gear shaft 21 by two planetary gears, which are each arranged within one of the cutting wheels 11.
  • the arrow 15 in turn indicates the feed direction in which the trench cutter is moved forward in its work.
  • FIG. 3 The arrangement according to the invention from FIG. 2 is shown in side view in FIG. 3.
  • the symmetrical arrangement of the two milling wheels 11 with respect to the bearing plate 13 can be clearly seen.
  • only a bevel gear 23 needs to be arranged on the sun gear shaft 21 in order to transmit the drive torque to the sun gear shaft 21 and thus to the planetary gears of the cutting wheels.
  • the arrangement of the drive units according to the invention shown in the front and side views in FIGS. 4 and 5 essentially corresponds in structure to the arrangement shown in FIGS. 2 and 3.
  • a chain gear 27 is provided instead of the bevel gear as a torque transmission device between the drive motor 9 and the sun gear shaft 21 of the planetary gear.
  • the chain transmission 27 consists essentially of a chain wheel 29 fastened to the drive motor, a chain 31 and a chain wheel 33 arranged on the sun wheel shaft.
  • the chain 31 connects the drive motor 9 and the sun wheel shaft 21 in the vertical direction and is protected on the one hand by the fact that it extends in a recess in the end shield 13 and on the other hand by the fact that it is encapsulated in the area between the drive motor 9 and the end shield 13, ie it is protected in this area with a housing 35 .
  • a fast-running chain 31 With this straight and direct transmission of the drive torque from the motor 9 to the sun gear shaft 21 and the associated planetary gear of the cutting wheels, it is possible to use a fast-running chain 31 with initially low drive torque, the torque in the planetary gear being increased in that the Speed is reduced and at the same time a high torque is generated by the large lever arms available in the milling wheels.
  • the geometric conditions in the milling wheels 11 are again so favorable here because the drive motor 9 is not arranged in the area of the milling wheels, but in the milling frame.
  • each cutter wheel 11, 11 ' is driven separately by a drive motor 9, 9' via a bevel gear 37, 37 'and a sun gear shaft 41, 41' of a planetary gear.
  • the Antribswellen 39, 39 'of the bevel gear 37, 37' seen from the front V-shaped between the drive motors 9.9 'and the output pinions of the bevel gear 37, 37' are arranged.
  • the two shafts 39, 39 ' run essentially parallel and at a distance from the center plane of the end shield 13.
  • the shafts of the bevel gearboxes shown in FIGS. 2 and 3 and 6 and 7 can be embodied encapsulated in their section between the drive motors 9, 9 'and the end shield 13.
