Definitions

  • the invention relates to a trench cutter for producing a trench wall in the ground, according to the preamble of the main claim.
  • Trench wall milling machines are known in which a hydraulic motor and the gear units are arranged for driving the milling wheels within the hub of the milling wheels. Oil is supplied through holes in the holding frame for the milling wheels. With these trench wall cutters, it is disadvantageous that both the drive motor and the gear units must be accommodated within the cutting wheels, so that very little space is available which could be used to generate a high torque. A further disadvantage of these devices is that a certain part of the hydraulic oil always leaks out of the lines and is lost when the transmission is changed.
  • the invention has for its object to provide a generic trench wall cutter, in which a particularly large torque is available at a given power of the drive motor on the cutting wheels and at the same time the cutting wheels have a very high effective milling width in relation to the entire slot width.
  • this object is achieved in that the drive motor is fastened to the milling frame in each case, that the gear device which connects the drive motor and the cutting wheel gear is in each case at least partially arranged in recesses in the end shield and that the cutting gear is designed as a multi-stage planetary gear.
  • 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 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 at the same time 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 cutting gear via a chain transmission with a chain and two sprockets.
  • 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 such 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 together.
  • 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 inventive arrangement of the drive motor in the milling frame also makes it possible to use commercially available hydraulic or electric motors of an appropriate size, since there are no restrictions in terms of installation space.
  • 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 of F ig. 2 shown in side view.
  • 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 essentially consists 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 runs in a recess in the bearing plate 13 and on the other hand by the fact that it is encapsulated in the area between the drive motor 9 and the bearing plate 13, ie it is in this area with a housing 35 protected.
  • FIGS. 6 and 7 The structure of the drive units according to the invention shown in FIGS. 6 and 7 essentially corresponds to the structure shown in FIGS. 2 and 3.
  • each milling 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 drive shafts 39, 39 'of the bevel gear 37, 37' seen from the front in a V-shape between the drive motors 9,9 'and the output pinions of the bevel gear 37, 37' are arranged. Seen from the side, the two shafts 39, 39 'run essentially parallel and at a distance from the center plane of the end shield 13.
  • the drive motor 9 ' , the shaft 39 ', the bevel gear 37' and the sun gear shaft 41 are shown in FIG 'drawn in the turned position.
  • the shafts of the bevel gear transmissions 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.
