Definitions

  • the invention relates to a loading system of the type specified in the preamble of claim 1.
  • a hydraulic cylinder which is responsible for swiveling the press wing arrangement forward, is supported on an overhead frame part and engages by means of a pull chain on a swivel lever arranged at the shaft end.
  • a second hydraulic cylinder which is responsible for pivoting the press wing assembly backwards, is anchored to the side wall. It also attacks the shaft via a tension member. Large-diameter deflection tubes serve to create favorable lever arms for the tensile forces of the two hydraulic cylinders.
  • the invention has for its object to provide a low-wear and low-maintenance loader of the type mentioned, in which manufacturing, assembly and operation-related tolerances and deformations have no influence on the functional reliability, so that the loader over long periods of time trouble-free the rough Working conditions has grown.
  • the components loaded with the reaction forces from the movement of the blade arrangement are attached and supported in and on the support part, which in turn is held directly on the frame parts.
  • the supporting part can be designed with little structural effort so that the occurring loads are absorbed properly.
  • the side wall does not need to be used for power transmission and can therefore be delicate.
  • the filling trough forms a unit with the overall structure of the loading unit, which is connected to the presser wing arrangement and its swivel drive only via the frame parts. Deformations, dimensional deviations and relative movements between these two units have no significant influence on the operational safety when the loading plant is in operation.
  • the Individual components of the swivel drive can form an encapsulated unit with the support part, which works with its own lubricant supply from external influences, ie from the outside of the loading plant and from the inside due to contamination from the processed waste, unaffected and reliable. For these reasons, long service life for the loading plant is achieved with negligible maintenance, even under the roughest working conditions.
  • the transmission of the reaction forces from the support part to the frame parts takes place torque-free through the spherical bearings for the frame parts, because the spherical bearings only transmit tensile and compressive forces, the frame parts of which are particularly well suited for receiving.
  • the embodiment of claim 3 is also advantageous because space is saved when the rack is structurally integrated into the piston rod.
  • the embodiment according to claim 6 is also structurally simple. A very stable mounting of the swivel drive next to the side wall is also achieved, because the spherical bearings are essentially movable only in the plane in which torques could result from the transmitted forces, while those standing perpendicular to it Directions the support part is kept very stable. By means of the support arm, a conveniently large lever arm for power transmission is created.
  • a mounting of the shaft which is independent of the side walls is achieved in the embodiment according to claim 7, wherein the measures according to claim 8 can usefully also be provided so that the shaft is driven on both sides of the presser vane arrangement.
  • the embodiment according to claim 9 is technically simple.
  • the spur gears are able to transmit even high forces or torques without problems and over long service lives.
  • it is Disassembly of the presser wing arrangement simply because only the spur gears have to be detached from each other.
  • the clamping devices are designed with an adjustable preload, the spur gears can serve as safety clutches that loosen when the pressing wing arrangement is blocked and thereby avoid damage.
  • the spur gears also have the advantage that the pressure wing arrangement can be easily installed in several angles of attack.
  • the tailgate 3 is open at least in the lower part at the rear and is laterally delimited by side walls 5.
  • Frame parts 6 and 7 at least partially encompass the side walls 5 and are connected to cross struts, not shown, so that they are sufficiently resistant to introduce forces without deforming the side walls 5.
  • In the lower part of the tailgate 3 there is a fill pan 8 with a rounded pan bottom which can be filled from the rear and leads to the inside of the refuse collection container 2 via a threshold (not shown).
  • the presser wing arrangement 9 consists of an approximately elliptical main wing 9b in cross section, on which an additional wing 9a, which can be moved with its lower comb close to the bottom of the tub, is pivoted in such a way that it moves when the pressed wing assembly 9 is moved clockwise up to the threshold to the garbage collector 2 to the bottom of the tub 8 travels along, while when the press wing assembly 9 moves counterclockwise it folds down relative to the main wing 9 b until the press wing assembly 9 is folded up and raised to such an extent that access to the fill tray 8 is free via the threshold 8 a.
  • a pivot drive 11 which is arranged on the outside next to the side wall 5, serves to move and hold the presser wing arrangement 9.
  • a mirror-image swivel drive 11a can be arranged, the other end the press wing assembly 9 supports and drives.
  • the swivel drive 11 (as well as the swivel drive 11a) consists of a block-shaped support part 12, which is designed as a hollow housing 13 and is equipped with two opposite rigid mounting brackets 14 and 15.
  • a hydraulic cylinder 16 is rigidly fastened to the support part 12, specifically by means of its cylinder housing, which in the present embodiment contains two hydraulic pistons 17 and 17a connected to one another via a piston rod 18.
  • a rack 19 or a rack profile is provided, which serves to drive a shaft 21 rotatably supported in the housing 13 in bearings 20.
  • the main wing 9b of the press wing assembly 9 is rotatably attached on the shaft 21, the main wing 9b of the press wing assembly 9 is rotatably attached.
  • the shaft 21 is interrupted between the shaft ends. However, it is conceivable to design the shaft 21 continuously.
  • the shaft ends penetrate both side walls 5.
  • the support part 12 is held on the frame parts 6 and 7 with two pivot bearings.
  • One swivel bearing is formed by an articulated bolt 24 engaging in the bearing bracket 14, which is seated in a bearing block 22 which is fixed with pins 23 on the frame part 6.
  • the second hinge bearing is located on the bearing bracket 15, which is pivotally connected to a hinge pin 27 with the free end of a support arm 26, which in turn is connected to the other end via a hinge pin 25 in Frame part 7 is pivotally supported.
  • a torque-free support of the swivel drive 11 on the frame parts 6, 7 is achieved with the two spherical bearings, because the spherical bearings only transmit tensile and compressive forces.
  • a toothed carrier 32 with a circumferential toothing 33 is attached in the housing 13, the circumferential toothing 33 being made of there is at least one tooth which engages in the rack 19, more precisely in a tooth recess 34 of the rack 19.
  • the hollow shaft section 21a is rotatably supported in the housing 13 at each shaft end with the coaxial hollow shaft sections 21a, 21b, while the other hollow shaft section 21b is connected to the main wing 9b via a connecting part 30.
  • a spur toothing 28 serves as a rotary coupling, which consists of spur tooth protrusions 28a and matching tooth recesses 28b.
  • a clamping element 29 clamps the two hollow shaft sections 21a and 21b against each other in the axial direction so that the spur toothing 28 transmits the torques in both directions of rotation and also ensures centering of the two hollow shaft sections 21a and 21b relative to one another.
  • the spur toothing 28 also has the advantage that it can compensate for slight misalignments or angular positions between the hollow shaft sections 21a and 21b and thus keeps the shaft 21 free from undesirable bending loads.
  • the housing 13 penetrates the side wall 5 with play in an opening 31, so that no forces are transmitted to the side wall 5 when the swivel drive 11 or 11a executes movements under the occurring forces.
  • the housing 13 is arranged outside the side wall 5; the shaft 21 passes through an opening 31 'of the side wall 5 in such a way that the end toothing 28 lies exactly in the region of the side wall 5.
  • the tensioning element 29 can pull the two hollow shaft sections 21a and 21b against one another with a preset preload, so that the torque transmission is interrupted in the case of excessive forces on the presser wing arrangement 9 due to the axial forces then generated in the end toothing 28. Furthermore, it would be conceivable to rigidly connect the hollow shaft sections 21a and 21b to one another or to provide another articulated coupling here.
  • FIG. 1 A further embodiment is indicated in FIG. 1, in which two cylinders 16 and 16a are arranged on each side of the shaft 21, the cylinders 16a also being connected to the other side of the shaft 21 via a rack (not shown) parallel to the rack 19 attack a peripheral toothing.
