Definitions

  • the present invention relates to a lifting device of the kind indicated in the preamble of independent claim 1.
  • Such a lifting device is employed when emptying refuse containers into a refuse collection vehicle.
  • the lifting device is particularly intended for use in emptying refuse containers having receptacles for more than one refuse fraction.
  • lifting devices in refuse collection vehicles, the devices being constructed as an elevator arrangement adjacent a collection bin provided in the vehicle.
  • the devices being constructed as an elevator arrangement adjacent a collection bin provided in the vehicle.
  • lifting devices provided with a lifting yoke arranged hinged in the refuse collection vehicle.
  • Such a lifting yoke is connected to a refuse container, and the container is then lifted above an emptying pocket provided in the collection bin along a substantially circular path. In the course of its path or well above the emptying pocket, the refuse container is turned for emptying the refuse into one or several emptying pockets.
  • the present invention allows the problems in known solutions to be substantially avoided.
  • the object of the invention is thus to provide a lifting device that is as easy to handle as possible and yet provides good reliability of operation. This object is achieved in accordance with the invention by the lifting device according to the invention having the characteristics de-scribed in claim 1.
  • the subsequent dependent claims specify suitable further enhancements and variants of the invention that further improve its performance.
  • the lifting device described in the present invention provides a plurality of significant advantages over the prior art. Accordingly, the invention enables considerable simplification of the emptying of containers comprising a plurality of adjacent receptacles; a construction that is becoming increasingly common as refuse sorting increases in society. Simplification of the tasks naturally brings about economic savings in the emptying of each individual refuse container, but it also brings about savings due to the capability of handling the emptying of a larger number of refuse containers with the same refuse collection vehicle.
  • the construction of the invention also allows all receptacles of the refuse container to be emptied on the same side of the collection bin. Besides simplifying the emptying of the refuse container, this also simplifies the construction and emptying of the collection bin.
  • the figures show the back part of a refuse collection vehicle 1, which also comprises a chassis, which is not shown, and a driver's cab.
  • the figures show a part of a collection bin 2, in which the refuse is transported from the collecting site to a waste treatment centre.
  • the collection bin is divided into four adjacent chambers 3 to 6 on top of each other by means of a perpendicular partition 7 and a horizontal separating plane 8 that extend in the longitudinal direction of the refuse collection vehicle. Both the height and width of the chambers can vary depending on the type of refuse intended to be transported with the vehicle.
  • the rear end of the collection bin is open for achieving at least one feeding and discharge opening.
  • the refuse collection vehicle 1 For feeding the refuse into the collection bin 2, the refuse collection vehicle 1 is provided, behind the bin, with at least one back part 9, often called a compressor, which pivots around an axis of rotation at the edge of the feeding and discharge opening.
  • the back part is provided with a discharge trough 10 to 13 according to Figure 1 for each chamber 3 to 6 provided in the collection bin for receiving collected refuse.
  • the back part also comprises a pivot plate movable along the bottom of the discharge trough by means of a hydraulic device for transporting the refuse to the feeding and discharge opening of the collection bin.
  • Both the collection bin and the back part have a conventional structure and they are therefore not described in more detail in this connection.
  • the refuse collection vehicle 1 For feeding the refuse into the collection bin 2, the refuse collection vehicle 1 comprises at least one lifting device 14 with which the refuse container can be tipped over the discharge troughs 10 to 13 of the back part 9.
  • the present embodiment of such a lifting device is utilized particularly in emptying refuse containers 15 or corresponding containers into an at least two-piece collection bin provided in the refuse collection vehicle.
  • the lifting device comprises a substantially U-shaped primary lifting yoke 16 preferably arranged hinged in the collection bin or back part of the refuse collection vehicle.
  • the lifting yoke comprises at least two substantially parallel lever arms 17 and 18 that extend from the collection bin in a direction behind the refuse collection vehicle.
  • a crossbar 19 provided with primary gripping means 20 is arranged in the lever arms.
  • the lifting yoke is arranged to use these means to grasp lifting fittings 21 provided in a refuse container brought alongside the refuse collection vehicle for the purpose of then being able to lift or turn the refuse container relative to the collection bin in a substantially vertical direction and then empty the container into the corresponding discharge trough in accordance with what is shown in Figures 2 to 4.
  • the container is two-piece and provided with a partition.
  • the container also comprises an insert or mounting in the form of a refuse cassette 22, which also preferably can be two-piece.
  • the present lifting device 14 comprises at least one secondary lifting yoke 23. It comprises at least a lever arm 24, which like the lever arms 17 and 18 in the primary lifting yoke 16, extends from the collection bin 2 in a direction behind the refuse collection vehicle 1 and is pivoted relative to the collection bin.
  • the lever arm comprises, in turn, at least one therein arranged secondary gripping means 25, which is arranged to grasp the refuse cassette and manoeuvre it to emptying.
  • the secondary lifting yoke 23 is preferably pivotally fastened above the primary lifting yoke 16. Accordingly, as shown in Figure 2, the travel path of the lifting yoke extends from its outer end taking a first end position at the primary gripping means for engaging the lifting fittings provided in a refuse cassette arranged in the refuse container to a second end position above the collection bin according to Figure 4 for tipping the refuse cassette over an upper discharge trough 12 or 13 provided in the collection bin.
  • the secondary lifting yoke 23 is brought in movement with a jack device 27 known per se. This device preferably comprises at least a regulating unit arranged to manoeuvre the lever arm of the lifting yoke.
  • the movements of the lifting device 14 can be divided into three main parts according to Figures 2, 3 and 4.
  • the primary lifting yoke 16 and particularly the gripping means 20 provided therein take a position alongside the refuse container 15 in the immediate vicinity of the primary lifting yoke.
  • the primary lifting yoke Once the primary lifting yoke has engaged the lifting fittings 21 provided in the refuse container, its lever arms 17 and 18 are arranged to take a position according to Figure 3, whereby the refuse container is slightly lifted from its base.
  • the gripping means 25 of the secondary lifting yoke 23 is able to grasp the lifting fittings 26 in the refuse cassette 22 of the refuse container, after which the refuse cassette is arranged to be released from the refuse container such that the lever arm is brought in a position substantially parallel above the lever arm 18 of the primary lifting yoke.
  • the lifting device is ready to initiate the actual lifting and emptying step.
  • the lifting step is initiated once the containers are brought against the corresponding emptying trough for emptying in accordance with Figure 4.
  • the lever arms are preferably manoeuvred with the above indicated dedicated jack device 27, which attends to the shifting of the corresponding lever arm from the initial stage of movement until the refuse container and cassette are emptied.
  • the lever arms are arranged to maintain a substantially symmetrical movement while the refuse container and the refuse cassette are lifted to their upper positions.
  • the emptying step is initiated.
  • the refuse container and the refuse cassette are rotated above the corresponding emptying through for reaching an end position where the contents of the containers are tipped into the emptying trough of the back part according to Figure 4.
  • the emptied containers then resume their substantially vertical position, after which the lifting yokes 16 and 23 are lowered and the refuse container and the refuse cassette resume their relative places and are restored to the ground.
  • the bar or regulating unit 28 that attends to the manoeuvring of the secondary lifting yoke 23 is preferably arranged at its one end in the lever arm 18 of the primary lifting yoke 16, and at its opposite end in the lever arm 24 of the secondary lifting yoke.
  • a regulating unit preferably comprises a pneumatic or hydraulic cylinder. Well-thought-out placing of the bar or the regulating unit allows the lifting yokes to be manoeuvred from their initial position to their emptying position in a single continuous movement.
