Definitions

  • the invention relates to a crawler vehicle for transporting heavy loads, in particular in an open-cast mine, with a frame, on the two sides of which the caterpillars are arranged and sit in the hydraulic lifting cylinders, which carry a platform which is guided against upward and downward movement by swash bearings against displacement forces is held.
  • Such a caterpillar vehicle is known from DE-PS 24 16 642.
  • the aforementioned swash bearing consists of a ball joint that sits on a cylinder-piston guide arranged in the center of the crawler vehicle and, at the same time, allows after driving under a load on supports, such as a belt drive station, and attaching the lifting platform to the underside of the load To hold the caterpillar exactly on the spot when turning caused by the caterpillars driving in opposite directions.
  • the invention has for its object to provide a caterpillar vehicle of the type described above with expanded possibilities.
  • a rotatable foot can be extended downwards on which the caterpillar vehicle can be supported with at least part of its weight.
  • Such a caterpillar vehicle can turn anywhere on the spot, regardless of a load object.
  • a hold is created on the one hand against the irregular thrust forces that arise unintentionally when the vehicle is rotated by means of the caterpillars, and these are reduced by the same part of the weight by relieving the caterpillars.
  • the caterpillar vehicle cannot move, or only insignificantly, when turning on the spot.
  • the relief provided for the caterpillars according to the invention also provides the advantage that the caterpillar vehicle digs less into the ground on the spot and then after the load has been picked up has a more favorable starting position on the lifting platform when moving off under load.
  • the weight of the vehicle can be shifted almost entirely onto the foot, so that the caterpillars carry almost nothing and are only rotary drives.
  • the weight portion of the crawler vehicle shifted to the foot will be 1/2 to 3/4, just enough that the foot offers sufficient support against the thrust forces.
  • the crawler vehicle can also be lifted off the ground with support on the foot and can be rotated on the foot by means of a rotary drive.
  • the foot is expediently extendable and the crawler vehicle can be supported thereon by means of a lifting cylinder seated in the frame, on which, more precisely: expediently on its piston rod, the foot is arranged.
  • the frame with the caterpillars can be displaced in the transverse direction above the extended foot, preferably by articulating the lifting cylinder on an axis parallel to the longitudinal axis of the frame and an actuating cylinder pivoting on the lifting cylinder.
  • the position of the caterpillar vehicle can be corrected again in any direction if necessary after turning, in the transport direction by caterpillar movement and in the transverse direction by displacement.
  • the foot is designed as a, preferably tumble-movable, preferably round, plate with a width that is 1/2 to 1 1/2 times the width of the caterpillars. With the plate, a footprint of sufficient size can be created to prevent the foot from sinking into the ground. Depending on the conditions of use of the crawler vehicle, especially the ground conditions, other things can also be considered.
  • the foot In order to secure the foot as effectively as possible against displacement, it can be provided with at least one stud, preferably a stud in the form of an annular bar.
  • the wobble bearing consists of two ball or spherical shell bearings seated on cylinder-piston guides, one of which is longitudinally displaceable in the direction of the other.
  • the two cylinder-piston guides can be arranged arbitrarily off-center.
  • the more extended lifting cylinders are aligned closer to the vertical in the case of an inclined arrangement than in the case of a parallel arrangement. They are therefore only minor Bending forces exposed that you want to avoid on hydraulic cylinders, especially when extended.
  • a caterpillar support 2 is arranged on each of the two sides of a frame 1, on which a caterpillar 3 is guided at the front and rear ends via a driven chain wheel 4 or 5 and in between via running wheels 6; a tensioning device is indicated at 7 for the rear sprocket 5.
  • the rigid crawler supports 2, which are not shown in detail, but are known, are articulated to the frame 1 near the longitudinal center via a horizontal transverse axis and are also connected to one another by a crossbeam 8 which is centered at the rear end of the frame 1 is pivotally mounted about a horizontal longitudinal axis 9 and acts on the two crawler supports 2 in joints which permit the caterpillar supports to be folded over by pivoting the crossbar 8 about the longitudinal axis 9.
  • four hydraulic lifting cylinders 10 are arranged rotationally symmetrically to the center of the frame and inclined to one another. They are only shown in FIGS. 1 and 3, not in FIGS. 2 and 4.
  • the lifting cylinders 10 carry a square or circular lifting platform 12 on the ends of their piston rods provided with flat heads 11.
  • the lifting platform 12 is secured against displacement by two cylinder-piston guides 15 which engage it with ball-cup bearings 13 and 14.
  • the ball-cup bearing 13 is displaceable in the lifting platform 12 in the direction of the ball-cup bearing 14, so that by Inclination of the lifting platform between the two spherical shell bearings 13th and 14 relative displacements can be accommodated.
  • a downwardly extendable lifting cylinder 16 is rigidly arranged in the center of the frame 1, on the piston rod 17 of which a foot 19 is attached in a ball joint 18 in a swivel and rotating manner.
  • the foot 19 has the shape of a round plate with a diameter that is slightly larger than the width of the caterpillars 3. On its underside, it is provided with an annular strip 20 that fulfills the function of a stud.
  • a pivotable lifting cylinder 21 with a piston rod 22 is provided, but with the same ball joint 18 and a foot 19 provided with an annular strip 20, the lifting cylinder 21 can be pivoted about an axis 23 which extends in the direction of travel of the crawler vehicle and is arranged in the frame 1 by means of an actuating cylinder 24 which is articulated at 25 on the frame 1 and at 26 on the lifting cylinder 21.
  • the pivotable lifting cylinder 21 with the actuating cylinder 24 offers the possibility of moving the entire crawler vehicle somewhat in the transverse direction in its extended position. This is easy to see from Fig. 4.
  • the lifting platform 12 is then raised by extending the lifting cylinders 10 and the load is picked up on it.
  • the load is brought into a horizontal position by means of a corresponding measuring and control device by differently extending the lifting cylinders 10. During transport it is kept in this position by constant monitoring and readjustment regardless of the slope changes etc. of the ground.
  • the lifting cylinder 16 could also be rotatably supported in the frame 1 by means of a rotary ball connection and be provided with a rotary drive which, on the foot, lifted the rest of the caterpillar vehicle completely off the ground by means of the lifting cylinder 16 and foot 19 turns.
  • a rigid connection would then be required instead of the ball joint 18. The same would be possible, albeit more complex, in the caterpillar vehicle according to FIGS. 3 and 4.
