Description

TECHNICAL AREA

The invention relates to a lifting and tipping device with support structure, with the Garbage containers are emptied into a garbage collection vehicle can. Such a lifting and tilting device is, for example attached to the rear of a refuse collection vehicle.

STATE OF THE ART

Lifting and tipping devices are the waste containers to be emptied and the location on the refuse collection vehicle trained differently. So-called rear loaders are Garbage collection vehicles where the garbage fill opening is in the area the rear end wall of the rear of the vehicle is. Below this garbage filler opening is the respective one Corresponding lifting and tipping device attached to waste containers.

In a garbage collection vehicle with a so-called low filling opening can not only the most diverse garbage containers Bulky goods can also be filled in loosely. So big ones too Items such as cabinet parts, sofas and the like from the garbage collectors can be thrown into the vehicle, the loading edge, i.e. the lower pouring edge of the filling opening be as low as possible.

Lift-tilt devices designed for such filling openings are known as so-called beam fill. Due to the they cannot build very low sills. Beams are therefore relatively low in construction. They are on the side boundary walls of the rear of the vehicle each attached. In addition, are on the boundary walls usually still cantilevered to the rear Diverter arms attached. With these transfer arms can be very large containers can be emptied into the stern.

If only smaller vessels, ie no large waste containers, are to be emptied into such a refuse collection vehicle, the vehicle can be equipped with a so-called high fill opening. For this purpose, the filling opening is closed in the area above the loading sill. A lifting and tilting device suitable for closed filling openings can then be attached via an intermediate frame attached to the rear. Smaller and larger waste containers, up to a size of 1.1 m ³ (cubic meters) can then be emptied. Bulky items can then no longer be put into the refuse collection vehicle.

The older EP-A-0 612 674 shows a refuse collection vehicle a relatively deep loading sill, in which the support structure for the lifting and tipping device at the rear of the vehicle is limited by the loading edge at the top, and thus between the side boundary walls of the rear of the vehicle is. The support structure has on the two side Edge areas of the rear of the vehicle each fastened first holding parts, between which a second holding part with the movable Divide the lifting and tilting device in the manner of a pivotable Door is attached by means of a hinge device.

PRESENTATION OF THE INVENTION

The invention has for its object an improved Lift-tilt device for rear loaders with a low fill opening specify.

This invention is given by the features of claim 1. Developments of the invention are the subject of dependent claims. The invention has the advantage that the boundary walls free of construction parts in the area of the rear of the vehicle this lift-tilt device can remain. The Invention uses the fact that the constructive training the loading edge in the prior art is sufficient is stable. It is therefore according to the invention easily possible, the lifting and tilting device only in the area to attach the loading sill to the rear of the vehicle. A constructive one Connection to the boundary walls or to the rear area below the loading sill is not necessary.

According to an essential embodiment of the invention Retaining structure for the lifting and tilting device sandwich-like, trained with a lower and upper structure. The A first substructure representing the holding part is on the refuse collection vehicle attached. This construction is designed that the lift-tilt device by simple adjustment measures can be attached to as many rear profiles as possible. The superstructure can be used on this substructure be attached. The superstructure, which is a second holding part represents for the lifting and tipping device, can then for all rear shapes should be of the same design. If this superstructure releasable for example via a screw connection attached to the substructure can be practical the entire lifting and tipping device quickly and easily from remove the refuse collection vehicle. Only the one at the loading sill fortified substructure, for example only in the outer lateral areas of the filling opening need to be is hardly a hindrance in the way. The Vehicle can therefore be used as a bulky vehicle.

All moving parts can then be attached to the superstructure the lifting and tipping device, which is used to lift and tilt the individual Garbage bins are required to be present.

A relevant advantageous embodiment of the invention has a tilting frame, which on the second holding part is pivotally mounted via tilt cylinder. This tipping frame in turn carries a pallet truck that has appropriate lifting cylinders can be adjusted. The pallet truck is then used for Inclusion of the waste containers to be emptied.

The lifting and tilting device according to the invention can be according to one essential Continuing education should be designed so that what is to be emptied The waste container hardly protrudes into the filling opening. To ensure that in this emptying position anyway all garbage through the fill opening into the Garbage collection vehicle falls into it, is a slide on the lifting and tipping device present in the emptying position of the Garbage container both placed under the opening of the garbage container is, as well as with its lower end in the rear of the refuse collection vehicle protrudes. This way the garbage can not damaged by the conveyor bucket in the rear of the vehicle become. This conveyor scoop is used to fill the Garbage from the rear area forward into the garbage collection vehicle to transport into it. The movement of the bucket can therefore be independent of the movement of the lifting and tilting device being controlled.

Further features and advantages of the invention result by the features specified in the subclaims as well as by the following exemplary embodiments.

WAYS OF CARRYING OUT THE INVENTION

From a refuse collection vehicle in the form of a so-called Rear loader is the area of its rear loading opening 10 shown. The loading opening 10 is laterally by a left and right boundary wall 12, 14 framed. The lower one The loading opening 10 is limited by a loading edge 16, which is only shown schematically. The loading sill 16, as will be explained further below, realized by different constructions. Thereby is taken into account that different rear training of Garbage collection vehicles can be present.

In the lateral area of the loading opening 10 are a left and right holding part 20, 22 available. Both holding parts 20, 22 consist of a plate-like profile construction. over an angle bracket 24 supports the holding part 20, 22 of on top of the loading sill 16. The angle bracket 24 is on that Holding part 20, 22 and welded to the loading sill 16. At the bottom The area of the holding part 20, 22 is also an angle bracket 26 available. Since this angle bracket 26 in its Location and formation of the respective cross-sectional shape of the loading sill 16 must be adjusted, since they are from below to the constructive Training forms of the loading edge 16 must adapt can the same at different heights on the holding part 20, 22 are attached. In the present case, the angle bracket 26 are screwed to the holding part 20, 22. It is however also possible, the angle bracket 26 on the holding part 20, 22 to be welded. The attachment of the angle bracket 26 is carried out on the construction of the loading edge 16, for example via a welded joint.

A superstructure is on the two holding parts 20, 22 attached. This superstructure forms a second holding part and consists of a left and right holding plate 30, 32. These holding plates 30, 32 are designed so that they the left and right holding parts 20, 22 screwed tight can be. It is therefore possible to hold the holding plates 30, 32 and thus the attachment for the lifting and tipping device on the To attach the rear of a vehicle detachably. In the state of the Technology is not possible because in the area of the side walls, in which the lifting and tilting device is attached, a screw connection due to their compared to Welded connections of greater overall height is not possible; side walls are namely a maximum at the side of the rear of one Vehicle attached to the largest possible loading opening enable.

The two holding plates 30, 32 are via a cross member 34 connected with each other. The holding plates 30, 32 and the cross member 34 thus form an H.

Two of the holding plates 30, 32 each protrude toward the rear Triangular plates 36, 38. In the area between these plates 36, 38 stems 40, 41 of a tilting structure 42 are mounted. The tilt axis 43 runs parallel in the present case to the loading edge 16. The stems 40, 41 of the tipping structure 42 are rigidly connected to one another via a crossbar 44. The stems 40, 41 can be tilted and thus also the tilting structure 42 in the area of each holding plate 30, 32 each arranged tilt cylinder 46, 48. The Tilt cylinder 46 is in the lower region of the holding plate 30 a bearing structure 50 attached. His cylinder rod 52 is articulated with its free end on the stem 40. By Extension of the cylinder rod 52 out of the tilt cylinder 46 the handle 40 can rotate counterclockwise about the tilt axis 43 can be tilted. In a comparable way, the im Area of the right holding plate 32 articulated tilt cylinder 48 the stem 41 tilted counterclockwise. As a result, the tilting structure 42 can be tilted about the tilting axis 43 stored.

On the tilting structure 42 is cantilevered upward Cantilever arms 54 attached a locking bar 56. Against this Locking bar 56 can be on the tilting structure 42 existing waste container created from below and thereby in the Emptying can be kept constructive, as this is in itself for locking strips is known in the prior art.

Cantilever arms 58 project downward on the tilting structure 42. These cantilever arms 58 can have lower support configurations 59 (FIG. 2, 3) for the or the garbage containers to be emptied, what is not shown in Fig. 1.

A lifting truck 60 is also attached to the tilting structure 42, of a corresponding substructure, the the tilting structure 42 is fixed in the plane of the tilting structure 42, up and down relative to the same, can be adjusted. This pallet truck 60 with its substructure is not shown in Fig. 1, but is the other figures 2 to 4 in terms of location. Its adjustment can, for example, be attached to the crossbar 44 Lift cylinders take place.

This pallet truck 60 has a comb receptacle 62, as they do for receiving waste containers in the prior art per se is known. Small garbage bins on the comb holder 62, such as shown in Fig. 4, can then from below against the locking bar 56 during its stroke-tilt movement be pressed.

Two folding arms 64 are also pivotally attached to the lifting truck 60. The folding arms 64 are also in the prior art known per se and are used to hold larger waste containers, as exemplified in FIG. 5 for a vessel 90 is shown.

The tilt structure 42 is in the area between its two Holding plates 30, 32 a slide 66 attached. The slide 66 consists of an obliquely arranged plate construction, the upper edge with an elastic Bar (rubber plate) 68 is provided. This bar 68 is attached to the slide 66 from below. The slide 66 is arranged so that they open the opening area of each of the waste containers to be emptied. The one from the garbage can Falling garbage thus slides over the slide 66 completely through the loading opening 10 in the rear of the corresponding Garbage collection vehicle inside. The strip 68 serves to that if the garbage can bump into each other and slide 66 no damage can occur and nevertheless position the slide as tightly as possible the garbage can can be made.

In Figures 2 and 3 are two different rear designs 70.2, 70.3 shown. Appropriate rear training 1 is only with its loading edge 16 in FIG. 1 shown schematically. The left holding part 20, and comparable Also the opposite right holding part 22, is supported with the angle bracket 24 from above on the Construction of the loading sill 16.2. The angle brackets 26.2, which are present in the lower region of the holding parts 20, 22, are in their position to the cross-sectional shape of the loading sill 16.2 customized. They are attached to the respective holding part 20, 22 that they are placed close to the loading sill 16.2 and can be attached there. On the holding parts 20, 22 is then the tilt structure 42 via six screw connections each 72, of which six holes 74 are shown in FIG. 1 are releasably attached.

The rear formation 70.3 shown in FIG. 3 is the same Tilt construction 42 available. The holding parts 20, 22 with the angle bracket 24 show no differences 2. The only difference is that Location of the lower angle bracket 26.3, that of the different Cross-sectional design of the loading sill 16.3 account bears that it now, in the present example in Fig. 3, compared to Fig. 2 deeper on the holding parts 20 or 22 is attached. The loading edge 16.3 is also like the loading edge 16.2 from above from the angle bracket 24 and framed from below by the angle bracket 26.3. This can the holding part 20 and in a comparable manner also the holding part 22 are firmly attached to the loading sill 16.2 or 16.3. The rest of the tilt structure 42 can consequently on the holding parts 20, 22 are releasably attached, as shown in Fig. 1st is represented visually. The tilt structure 42 is in their training is therefore independent of the individual cross-sectional training the rear training 70.2 and 70.3 a rear loader.

In the upper area of the rear training 70.2 and if necessary A rear construction is also used for the rear training 70.3 78 attached to the rear of the vehicle. With this restraint construction 78 can cover 88 of a larger waste container 90, as shown in Fig. 5, during the emptying process pushed on and held in the open position, as described in more detail in connection with FIG. 5 becomes.

4 shows a further rear formation 70.4. Again, the holding part 20 or 22 sits with his Angle bracket 24 from above on a loading sill 16.4. From the holding part 20 is supported below via the angle bracket 26.4 at the loading sill 16.4. The location and where appropriate The cross-sectional shape of this angle bracket 26.4 is the only one Component of the cross-sectional shape of the loading sill 16.4 dependent on this rear training 70.4.

4 is a smaller waste container 80 in its lower position and its upper emptying position shown. The folding arm 64 shown in Fig. 4 is usually swung in vertically into the sheet plane be because it is only for holding larger waste containers 90 (Fig. 5) is needed.

4 that the cover 82 of the waste container 80 only insignificantly into the interior of the Tail training 70.4 swings in. This is damage the lid 82 and also the other parts of the waste container 80 by shovels in the rear training area 70.4 are pivotally and slidably mounted, not possible.

To empty the vessel 80, the same is in the area of Lift truck 60 brought. By raising the pallet truck to at the top (double arrow 84) is the upper edge of the envelope Vessel 80 from below against the locking bar 56. Then the tilt cylinder 46 (48) is actuated and the Tilt structure 42 tilted counterclockwise. The container 80 then reaches its upper emptying position 80.1 (Fig. 4). The garbage slips out of the container into the rear of the Vehicle. The on the holding plates 30, 32 and the Cross member 34 fixedly attached rusch 66 ensures that all garbage from container 80.1 also falls into the garbage truck.

5 is the emptying of a larger waste container 90 shown. The vessel 90 is replaced by the existing on the truck 60 gripped two folding arms 64, just like this taken in the prior art is known. By extending the required tilting cylinder 46 becomes the tilting construction 42 pivoted counterclockwise. The vessel 90 arrives via a middle position 90.1 to its emptying position 90.2, which are each shown in dash-dot lines. In the Position 90.1 reaches the side of cover 88 on the right and on the left in each case projecting pins 92 in the area of the retaining structure 78. One on the retention structure 78 Tab 94 attached at the end engages under the pin 92. When the vessel 90.1 is tilted further, the pin 92 slips on the upper cantilever 96 of the restraint structure 78 along. In the emptying position 90.2, this pin 92 taken his position 92.2. The firmly connected to the pin 92 Cover 88 is therefore swung open. The one in the jar 90 existing garbage can be freely from the container in position 90.2 fall out. Here, too, the slide 66 prevents Garbage could not fall completely into the rear.

In the rear formation 70.5 shown in FIG Loading sill 16.5 available, the top one in cross section has circular bars 16.6. On this bar 16.6 supports the angle bracket 24, as above is already described in the other rear training. From below is again the angle bracket 26.5 on the loading edge 16.5 attached.

All lifting and tipping devices have the advantage that they are practical only the lower angle bracket 26 of the respective cross-sectional shape to be adapted to the loading sill construction 16 needs. In addition, it is possible for the first time, the lifting and tilting device to be releasably attached to the refuse collection vehicle. The lifting and tilting device is therefore interchangeable. Only the small-area construction parts of the two holding parts 20, 22 remain in the area of the loading sill and can there, because then they are not in the way, over a Welded connection, for example, be arranged in a fixed manner. The other construction of the lifting and tipping device can be detachably attached become. The side walls delimiting the loading opening of the rear loader remain with the present invention Lift-tilt device free of any construction parts this lifting and tipping device. The sidewalls therefore represent the full area for bearing constructions of Umleer arms available by means of which large dumpsters on the Loading opening can be positioned and emptied.

The lifting and tilting device shown above in the figures can also be in the form of a single emptying device a twin or in the form of a double fill become. In this way, the tilting structure 42 can also be divided are formed so that smaller vessels 80 independently of one another and also larger vessels 90 by simultaneous support with an envelope edge on both of them Pallet truck of the tipping structure 42 can be emptied. Both Tilt structures and their two pallet trucks then run in sync with each other, as in the prior art for Double-stroke tilting devices is basically known.

Of the lifting and tipping device shown above are the Cable routing and circuit arrangements for the pressure medium circuits not shown, since this is basically in State of the art are known. Constructive are also known Details of lifting and tipping devices, such as 58 attached in the lower area of the cantilever arms Support plates for vessels 80.
