Definitions

  • the invention relates to a device for cutting or cutting of material on a substantially flat mining front with a cutting tool, which at least from one two cantilever arm parts pivotable relative to each other existing swivel arm is rotatably mounted, the pivot axis of the cantilever arm and the pivot axes of the cantilever arm parts penetrate the working face.
  • a device of the type mentioned is from the AT 380 925 B known.
  • the well-known establishment aimed to create a cutting machine seen in the direction of advance with a very short design is enough, whereby at the same time the expansion of the route to close to the face without interrupting the cutting work and without endangering or impairing is possible.
  • the swiveling boom parts are pivotable about axes, which are essentially normal are aimed at the working face, so that for the lower cantilever arm part a swivel angle of at least 180 ° and for the cantilever arm parts mounted on this first pivotable cantilever arm part a correspondingly larger swivel angle is required is actually a with a corresponding swivel position to be able to dismantle the level face.
  • a swivel angle of at least 180 ° and for the cantilever arm parts mounted on this first pivotable cantilever arm part a correspondingly larger swivel angle is required is actually a with a corresponding swivel position to be able to dismantle the level face.
  • These rotary actuator naturally also has to absorb reaction forces when cutting. conditioned through the required swivel angle, in particular the required Swivel angle for a first swiveling arm part separate articulated other boom parts conventional cylinder piston units as drive.
  • Rotary drive which is conventional in cutting machines Way could be designed as a hydraulic motor requires but now for exact positioning and for a safe one Absorption of the cutting forces a reduction gear, which ensures a high reduction.
  • the one used Reduction gears must also be protected be and the invention aims to provide a facility of to create the type mentioned, its reduction gear the overall length seen in the direction of advance is not increased and can be accommodated in the smallest of spaces.
  • the invention further aims at such a reduction gear to design that in addition to a short design also a high Reduction and a safe arrangement in the respective Sharping arm or cantilever arm parts is made possible.
  • this object is the inventive device in essential in that coaxial to the pivot axes of the cantilever arms or the cantilever arm parts planetary gear arranged which are the speed of rotary actuators for the part-turn actuator to a reduced swivel speed of the cantilever arm or the extension arm parts.
  • planetary gear arranged which are the speed of rotary actuators for the part-turn actuator to a reduced swivel speed of the cantilever arm or the extension arm parts.
  • the training according to the invention is advantageous hiebei so that the gearbox in the area of Swivel axes are constructed identically and are each driven Sun gear a plurality of mounted on a carrier revolving planet gears and one divided in the axial direction have two-part ring gear, the ring gear parts rotatably fixed in different parts of the cantilever arm are.
  • Such a two-part divided in the axial direction Ring gear provides a particularly high gear ratio at extreme short overall length seen in the axial direction.
  • the planet gears must be driven with the sun gear circulate with their carrier.
  • the training is advantageously taken so that the Planet gears in the axially adjacent ring gear parts on different Rotate pitch circle diameters.
  • a so-called profile shift be the planet gears are made in one piece can.
  • a profile shift inwards and in the abortion Ring gear part which rotatably with the previous cantilever arm part pivotally mounted cantilever arm part connected is a profile shift to the outside.
  • the pitch circle diameter results result from the multiplication of the module and the number of teeth.
  • the training according to the invention is thus advantageous hit that the number of teeth of adjacent ring gear parts around at least one, preferably three to four, different from one another is, which results in a particularly high reduction results in the smallest overall length in the axial direction is required.
  • the rotary drives can be operated in a particularly simple manner be formed by hydraulic motors.
  • a particularly small space requirement for the extension arm results is characterized in that the abortive ring gear of the first gear stage and the fixed ring gear part of the planetary gear of the outer boom in the same vertical plane is.
  • FIG. 1 shows a schematic side view a cutting machine according to the invention
  • Fig. 2 shows a section through the gears in the cutter or cantilever arm parts
  • Fig. 3 is a view in the direction of arrow III of Fig. 1 partially on average.
  • a cutting machine 1 is shown, the stationary Machine frame is designated 2.
  • a L-shaped carriage in side view the upward projecting end area designed as a portal designated 3 is.
  • the slide encompasses a guide tube 5 via tabs 4, which in turn is connected to the rigid machine frame 2 is.
  • the carriage and in particular the portal-like end 3 of the Carriage on which the boom arms 6 and 7 about pivot axes 8 and 9 are rotatably mounted, can be relative to the total Machine frame 2 in the direction of the double arrow 10 to the face move without the machine itself with its Crawler chassis 11 must be moved.
  • An anchor drilling and setting device is indicated schematically at 12. To the distance a between the positions in which the anchor drilling and setting device 12 comes into effect and keeping the face 30 as small as possible remains for the cantilever arm parts 6, 7 their respective drive, one Schrämmotor 13 and a cutting head 14 only a small space, the dimensions in the axial direction can only be achieved by appropriate construction of the drive and the gear for the cantilever arm parts 6 and 7 can be reduced accordingly. The details this drive are shown in Fig. 2.
  • a hydraulic motor 15 is provided which is driven by a Gear train 16 is connected to a sun gear 17.
  • the gear train 16 can hiebei formed for example as a chain drive his.
  • the ring gear in which the planet gears 18 engage, is formed divided, with a first ring gear part 19 is permanently connected to the portal 3, with which the Planet wheels 18 are driven to rotate around the axis 8.
  • the output takes place via the second ring gear part 20, which stationary again with the first swiveling cantilever arm part 6 connected is.
  • the number of teeth in the ring gear parts 19 and 20 differs from each other, so that uniformly trained Planet gear 18 here a corresponding speed reduction takes place and a high gear ratio is set.
  • the drive for the second cantilever arm part is analogous 7 trained.
  • the hydraulic motor is designated here by 21 and drives a central sun gear 22.
  • this sun gear 22 can be seen that this Sun gear is hollow and an axial bore 23 for the implementation of hydraulic lines, which consistently arranged protected inside the cantilever arm parts 6 and 7 can be and also for cutting drive for the cutting head 14th to lead.
