Definitions

  • the invention relates to a dust-bin lifting and tipping device for lifting the dust-bin off the ground and subsequently tipping it into a dumping chamber provided at the rear of a dust-cart, on which the lift-tipping device is mounted.
  • Lift-tippers are already known in which pressure medium acts on pistons in cylinders thereby lifting the dust-bin. Shortly before the .end of their stroke the lifting pistons slide over bores in the cylinder walls and thereby open a passage for thepressure medium to pass to the'tipping cylinders in which the pressure medium now acts on pistons which in turn effect the tipping of the dust-bin.
  • Lift-tippers are also known in which pistons in elongated cylinders are acted upon by pressure medium, said pistons being connected by piston rods, ropes and pulleys with a lift carriage for the dust-bin. T he piston movement in the elongated cylinders first causes the lifting and then also the tipping of the lift carriage carrying the dust-bin and capable of swinging out of guide tracks.
  • the first of said forms of construction is complicated, expensive to produce and requires continual service, whereas in the second form of construction the long cylinders and the necessary ropes and pulleys require a considerable amount of space, give rise to accidents and hamper the attendants in their work.
  • the invention sets out to provide a lift-tipper which is of simple, moderately cheap and reliable construction and which, moreover, requires little attention.
  • Fig. 1 is a side elevation of a lift-tipping device with a dust-bin standing on the ground;
  • Fig. 2 is a similar view showing the dust-bin raised from the ground and with the tipping frame swinging outwards;
  • Fig. 3 is a similar view with the dust-bin swung upwards into emptying position
  • Fig. 4 is a front elevation of the device in inoperative position
  • Figs. 5 and 6 are side elevations of a frontplate locking mechanism
  • Fig. 7 is a front elevation of the for the front plate
  • Fig. 8 is a side elevation similar to Fig. 1, but showing a modified form of construction with the dust-bin resting on the ground.
  • a-dumping chamber 1 is arranged on the rear wall 5 of a dust-cart andnormally closed on the outer side in known manner by-a front plate 2 oscillatable about a pivotaxle v4.
  • the front plate 2 has an aperture which is normally closed by an an oscillatable cover flap 3.
  • the front plate 2 also locking mechanism carries a known returning device which is not shown in the drawings.
  • a dust-bin 36 provided with a lid is swung together with the front plate 2 into the dumping chamber 1, the returning device being thereby placed under tension and the closing flap 3 and the dust-bin lid opened so that the refuse can slide out of the dust-bin through the aperture in the front plate 2 into the dust-cart.
  • Fig. 3 shows the front plate 2 in swung-in position, with the closing flap 3 and the dust-bin lid opened. 4
  • the bracket 7 carries a ball cup 8 in which a hollow piston rod 11 having a longitudinal bore and operating in a tipping cylinder .12 is movably mounted by means of a ball.
  • the free end of the bracket 7 carries .two rubber pads 9 and a run-on track 10.
  • the tipping cylinder 12 has at its upper end an eye 13 which is connected with two guide rails 22 by means of a pivot bolt 21 (see Figs. 1 to 3 and 8).
  • the front plate 2 is provided with two lugs 14 for receiving a bearing bolt 16 on which the two guide rails I 22 are pivoted by means of eyes 38.
  • the guide rails 22 are rigidly connected at their lower ends by a reinforcement strap 23 so that they form a tip frame 22, 23, 38.
  • a lift carriage 28 is arranged which carries on its longitudinal sides pairsv of upper and lower guide rollers 30 and 31, respectively, adapted to run in the guide rails 22-which are of U-section.
  • the lift carriage 28 has at its upper end a pair of suspension hooks 34 on which'the dust-bin 36 hangs during the upward movement of the 1 lift carriage 28.
  • the extreme upper end of the lift carriage 28 is also provided on each side with a semi- 22 is pivotally connected at its upper end to the bearing bolt 16 by an eye 39.
  • a piston, not shown, is slidable in the lifting cylinder 24 and has its piston rod 26 connected to the lift carriage 28 by means of nuts 27.
  • a conduit 40 leads from a compressor pump, not shown, to a pressure hose 44 which in turn is connected to the lifting cylinder 24 below its piston by means of a nipple 25.
  • Another conduit 41 leads from the conduit 40 to the hollow piston rod 11 of the tipping cylinder 12 via a check valve 42 with fitted exchangeable nozzle and a second pressure hose 43.
  • Finally a third conduit 45 leads from the pressure medium feed conduit 40 to a return conduit 48 for the pressure medium via a control valve 46 equipped with a hand lever 47.
  • locking assemblies generally designated by 20 are mounted on the dumping chamber 1 below the pivot 4 of the front plate 2 on the right and left of the guide rails 22, each of said assemblies 20 comprising a bolt 18 for an oscillatable control arm 17 with locking hook. 15.
  • a pressure spring 19 acts on an extension 17 of the control arm 17 to urge the locking book 15 into engagement with a nose 15 on the front plate 2, with the result that the front plate 2 is firmly held in its position of rest.
  • a compressor pump When the device is at rest a compressor pump, not shown in the drawings, supplies pressure medium through the conduits 40, 45 and the open control valve 46 into the returnconduit 48 so that the pressure medium merely circulates idly and exerts no pressure.
  • the rise in pressure of the pressure medium acts on the annular surface of the position in the lifting cylinder 24 and shifts the piston with its rod 26 in upward direction so that the lift carriage 28, hitherto engaging a lower lift stop 37, is also moved upwards.
  • the tipping cylinder 12, the piston of which is simultaneously acted upon by the pressure medium, remains for the time being in its position of rest as will be hereinafter explained.
  • the tipping device remains at rest because the central axis of the tipping cylinder 12, the bolt 21 on the guide rails 22, and the bearing bolt 16 on the front plate 2 on which the guide rails 22 are pivoted, are located almost in a straight line, so that the pressure exerted by the pressure medium cannot take effect. Furthermore, the face of the piston acted upon by the pressure medium in the lifting cylinder 24 is of smaller diameter than the face of the piston acted upon by the pressure medium in the tipping cylinder 12, the ratio being such that, according to the work to be performed, first the upward movement of the lift carriage 28 with the dust-bin 36 suspended thereon takes place, while the tipping device still remains at rest.
  • the run-on roller 29 on the lift carriage 28 rolls along the inclined run-on track 10, as above described, and swings the guide rails 22 slightly to the right about the bearing bolt 16, as shown in Fig. 2.
  • the tipping cylinder 12 is brought to a more favorable engaging position on the guide rails 22, so that a swing movement about the bearing bolt 16 is imparted to the tipping frame formed by the guide rails 22 and the reinforcing strap 23.
  • the lift carriage 28 has reached its highest position and the lifting cylinder 24, being full, cannot take any more pressure medium, the pressure medium is now compelled to flow through the check valve 42, the pressure hose 43, the hollow piston rod 11 and the piston provided with a bore, into the tipping cylinder 12, the pressure of the pressure medium being further increased, if required, by the pressure medium pump.
  • the piston rod 11 is supported through the intermediary of its ball in the ball cup 8, whereas the tipping cylinder 12, through the intermediary of its eye 13 and the bolt 21, swings the guide rails 22, the lift carriage 28 and the suspended dust-bin 36, about the bearing bolt 16 acting as pivot axle.
  • the tipping cylinder 12 moves upwards along the stationary piston and the piston rod 11.
  • the front plate 2 remains in its position of rest (Fig. 1), until the dust-bin 36 bears with its upper edge and lid against the front plate 2.
  • the bearing bolt 16 for the guide rails 22 is mounted in lugs 14 on the front plate 2, these lugs 14 act as lever arm in relation to the pivot 4 of the front plate 2, so that a locking device is provided to hold the front plate 2 temporarily in its initial position.
  • a control bolt 49 arranged on the guide rails 22, as shown in Figs.
  • the control valve 46 When the refuse has slipped out of the dust-bin 36 into the dust-cart the control valve 46 is shifted by manipulating the hand lever 47 and opens the outlet for the pressure medium to flow into the return conduit 48.
  • the tensioned returningdevice now swings the front plate 2 and the other parts out of the dumping chamber 1 so that the tipping frame 22, 23, 38, the lift carriage 28 and the dustbin 36 are brought back into their initial position by their own weight.
  • the nose 15 presses the locking hook 15 out of its inoperative position against the pressure exerted by the spring 19, whereupon the hook again engages the nose 15 and locks the front plate 2 in its position i of rest.
  • a lift-tipping device particularly for dust-bins comprising a lifting cylinder with piston, a tipping cylinder with piston, a pressure medium feed conduit means leading to both of said cylinders, a common control valve having one side connected to said feed conduit means for uniformly and simultaneously supplying pressure medium to both of said cylinders, a return conduit for the pressure medium connected to the other side of said control valve, a dumping chamber arranged on the rear wall of a dust-cart, a pivot axle on said dumping chamber, a front plate mounted on said pivot axle, a bearing bolt on said front plate, a tipping frame pivotally mounted along with said lifting cylinder on said bearing bolt, a lift carriage adapted to carry a dust-bin and mounted for upward and dc.
  • the tipping cylinder being at its upper end normally hingedly connected at such an angle to the tipping frame so that the pressure medium will act first on the piston in the lifting cylinder and subsequently will cause a displacement of the tipping cylinder relatively to its piston, run on roller and track means operable at the end of the movement of the lift carriage for initially tilting said tipping frame with respect to said tipping cylinder so as to facilitate the subsequent displacement of the tipping cylinder relatively to its piston, an eye on said lifting cylinder in the path of said lift carriage and defining the upper end of its upward movement, the arrangement of said tipping cylinder, said lifting cylinder, liftcarriage and said run on roller and trackmeans :being such that the dust-bin is first raised by said lift carriage until the latter engages the eye on said lifting cylinder, whereupon the tipping frame together with the lift carriage and dust-bin are swung about said eye by the tipping cylinder so that the dustbin comes to bear against the front plate of the dumping chamber and then the front plate
  • a lift-tipping device as set forth in claim 1, where in the lift carriage is provided with rollers running in guide rails of U-section forming part of the tipping frame and carries at its lower end a run-on roller cooperating with an inclined run-on track mounted on a bracket on vthe rear wall of the dust-cart, the arrangement being such that the tipping frame together with the lift carriage and the dust-bin carried thereby are swung away from the wall of the dust-cart when the lift carriage has substantially reached the end of its upward movement.
  • tipping frame is at each side operatively connected by a control -bolt to an oscillatable control arm and a locking hook mounted on the dumping chamber and adapted to cooperate with a nose on the front plate in such a manner that the locking hook only disengages the nose on the front plate when the upper edge of the dustbin comes to bear against the front plate during the swinging movement imparted to the dust-bin by the tipping cylinder.
