Definitions

• the rear superstructure is a nuisance when setting down these holds, if you do not want to remove the container with forklifts at the various transfer points across the vehicle, but rather use standard drop-off containers with parking supports.
• the container is lifted by the vehicle using the air suspension or a rocker, then the supports are brought into the parking position and the vehicle is moved under this container with the rear loading device and loading bridge lowered.
• the rear loading device which is often too wide, is a nuisance here. It usually builds very long and is therefore too high in the horizontally folded state to be able to pass under the container with standard supports enable. However, the standard height of the parking supports on the container is necessary in order to be able to use standard container transport vehicles.
• Garbage trucks with front loading devices have therefore been developed (e.g. DE 42 04 062, 42 03 119), in which the garbage containers are swiveled over the cab to empty them and the container is filled from above. It can be set back without disturbing rear superstructures.
• this construction has the disadvantage that the process for emptying the container through the cab is slow. With approx. 1200 garbage containers being emptied per day, an additional effort of a few seconds per emptying means a significant increase in the price of the collection.
• DE 27 27 492 proposed the rotation of the entire body, which, however, reduces the payload of the vehicle due to the heavy body and is cumbersome.
• EP 0 588 033 the rear body is completely decoupled from the vehicle and parked. This requires an exact, lengthy docking and the reconnection of the supply lines such as hydraulic lines, which should be avoided due to any air pockets due to the separation.
• DE 4331750 sees the solution to the problem of decoupling the loading unit and container by opening the rear side, but this requires a lot of space and the container may also have to be made narrower in order to fit through a fastening frame for the opening device, which increases the transport volume belittles.
• DE 4301566 shows a rear-side closure of such a container, which is brought into a closed position with the loading mechanism, around actuators save. This leads to problems when unloading the container - as in DE 1225546 - when it is uncoupled from the vehicle, since the flap can swing open about a pivot point. The garbage will fall out in an uncontrolled manner after unlocking the rear wall. This is also not solved in the documents EP 0201313, DE 2105830, DE 2312856.
• the openings for pressing the garbage into the container by means of the loading mechanism are usually kept small, as a result of which the garbage in the container is compacted only over a small area, see also DE 2407615.
• the garbage which is expanding on all sides, will prevent the slide shown there from “sinking away from the garbage receiving opening due to its own weight" when the rear loading device swings away.
• the disadvantage here is the abrasion and the need for maintenance in the area of the shield guide. Since the loaded garbage is rarely homogeneous in the vehicle, strong asymmetrical forces act on the plate and its guidance and usually cause abrasive damage. An improvement is to be brought about here too.
• the object of the invention is, on the one hand, to design a garbage truck with an overall arrangement of the rear loading part and dumping device, which allows the rear part and / or the dumping device to be designed such that they enable the loading space container to be driven under in the horizontally folded-down state, without the need for this Usual length of the loading rear must be changed and without lengthy docking processes are required or the volume of the container must be reduced by fasteners for the rear part.
• the garbage truck should include a storage container, which may enable good garbage compaction and still allow the garbage to be safely parked and emptied at all times. There is a further problem in the compression of the substances in the container, since the use of conventional hydraulic presses, as with fixed bodies, is difficult
• the dumping device or parts of the rear are articulated and fastened in such a way that they can be divided into several parts by swiveling away from the rear part about one or more horizontal axes and with the (horizontal) underride position of the rear part having the required space. It makes sense that all elements of the rear, including the bed if necessary, are designed so that they remain coupled to each other.
• the settling container is provided with a roller shutter-type closure, which keeps the container securely closed even when it is parked. Furthermore, it can be opened and closed at any time and in a force-controlled manner by means of actuating devices, which preferably operate hydraulically.
• the known compression plate attached in the container is actuated, for example, by means of a cable or chain hoist or a pairing of gear / chain or rack, the Drive is arranged in a room encapsulated by garbage.
• the shield is preferably driven via a shaft located behind the shield or is equipped there with an impeller for the chain.
• This drive unit is installed protected from the garbage. Your motor or the drive unit can also be attached interchangeably and thus make the deposit container cheap. If there is no compaction label, e.g. for bio-waste loading, the transport container is conically extended to the driver's cab, there with a large-area lock and provided on the rear with hanging means such as hooks, eyelets etc. in order to be emptied to the front after being set down.
• a uniform guidance of the shield is achieved by a rigid coupling, for example by means of a shaft as a transmission element, which the forces of the different sides of the shield or position guides each transfers to the other side.
• the position of the shield drive can be corrected, for example, by means of guide claws (which are preferably attached to the top of the storage space and work in a form-fitting manner - similar to an escapement of a watch - using the press shield) with a rotatable or swiveling connecting crossbar.
• FIGS. 1 a to 1 c show a lift-and-tilt device (4) on the rear loading device (3) of a garbage truck (1).
• the usual fastening rail (9) preferably has on its upper side an axis of rotation or a joint (6 ") around which the entire lifting and tilting device can be rotated. Further axes of rotation for the rear attachment are 6 and 6 ⁇ .
• the fastening rail (9 ) is in the lower area preferably held by automatically snapping fastening bolts or hooks (10).
• the supply lines for hydraulics and electrics are designed flexibly in the area of the upper axis of rotation (6 V ”) and are laid so that they can follow the outward movement (arrow A) of the pouring device. It is therefore not necessary to disconnect these devices.
• the actuation of the folding hydraulic system can be switched on automatically by opening the lock (10) up to a stop (10a) (FIG. 1 a). This ensures correct operation
• the hydraulics can be folded down safely, and the dumping device attached to the rear can also be folded down by, for example, inserting a spreading wedge or a cam disk between the rear of the vehicle and the pouring frame, which causes spreading when the fill is raised.
• the axis of rotation (6 "") can also be set significantly lower (item arrow B), which means the maneuverability of the vehicle due to the shorter design of the folded device improved under the storage container.
• Fig. 2 shows a further advantageous division of the loading tail using the example of a two-chamber vehicle with a horizontal dividing wall (13a) divided container (2a, 2b), the rear (3a, 3b) of which is also divided by a horizontal dividing wall (13b) into an upper and lower part and thus the filling of different types of waste via the rear openings ( 14a, 14b) with the help of the partition (13c).
• the clearing blades (15a, 15b) work through the drive shafts (16a, 16b) located close to the container.
• the selected division of the rear creates no problems of power flow due to its location behind the drive shafts and enables a further subdivision for driving through the rear part of the garbage truck under the skip container.
• the rear part, the rear wall of the rear part, parts thereof or particularly protruding parts can be pivoted in this example (axis of rotation 6 ""), so that in the (approximately) horizontal state a small height allows easy passage under the container.
• care must generally be taken to ensure that the power flow in the rear section is structurally satisfied when the loading and / or dumping device is in operation.
• further parts which interfere with driving under such as parts of the loading trough of the rear part, the ride for the garbage workers, lamps etc. can be removed from the critical space.
• the fastening of the rear part located closer to the container in the vertical loading position on the vehicle can be ensured by optionally automatically engaging bolts and similar known means.
• FIGS. 3a and 3b show a storage container (2) which, in principle, regardless of whether it is loaded from the front, from the side or from the rear, can be securely closed by means of a roller door (51).
• 3a shows a lower container (2) with loading device (3) and FIG. 3b the Container (2) alone.
• the guide rails (52) do not get clogged with garbage at the lower end, it is advantageous not to let the roller door guide (e.g. guide wheels or bolts) start at the lower end of the roller door, but somewhat offset upwards (e.g. 15-20 cm ) and let the lower ends of the guide rails open or run out on at least one side in the longitudinal direction of the vehicle (item 62).
• the guide wheels or bolts can also be designed conically so that they push the waste out of the guide to the inside of the container during the closing movement.
• the opening (34) of the container (2) is closed by segments (50) of a roller shutter-like closure (51) which are connected to one another via joints (58).
• These guides can e.g. B. be flexibly covered against the ingress of garbage.
• the segments are guided laterally in rails (52), which are either fixed to the container or are displaceable or rotatable (for example pivotable about an upper pivot point P).
• the roller shutter-like container closure can be opened or closed by means of at least one actuator such as hydraulic pistons (53).
• the closure is easier due to the relaxation of the garbage, possibly manually, z. B. pull up in a known manner on a rope and a crank.
• the clearing plate (55) (when the garbage must be cleared, the roller door must of course be open) works beyond the vertical to compress the garbage in the container so that the space in the closure area is completely free of garbage. This ensures a clean closure of the container.
• the garbage adjacent to the roller door in particular in the lower end position of the closing segment (59), to be directed against the garbage Conveying inward swiveling this final segment to be conveyed in (eg by curve control of the segment in the rail (52) or by division of the segment with a spreading actuation (curve control, hydraulics).
• the roller door should be close to the one in the lower vertical position clearing plate located when closing.
• the container (here towards the front) can be conically expanded in a known manner so that it can be emptied by lifting from the rear side allow.
• the garbage can be pressed in the container (2) by means of a scraper plate (55) and a compacting device (press and scraper plate 21) shown by way of example in FIG. 4. Because of the then expansive forces in the garbage, it is advantageous not to guide the closure elements (50) when opening, but in the container, but over the top (56) of the container. The closure is thus easy to move, in particular if it is simultaneously guided in a rail (52) which is movably mounted (arrow D).
• a safety catch such as a safety catch (54).
• Figures 4a, 4b (with a fixed) and 4c (with a rotating chain) show a known press and clearing plate (21) in the container (2), which by a cable or chain hoist (29) for compacting and clearing out the garbage in the longitudinal direction of the Containers is moved via an example drive (22) with a drive wheel (30) and engagement pins or teeth (31), which is protected behind the press plate.
• the energy supply for driving the shield (21) takes place As is known, via hydraulic or power lines laid in flexible protective device (23).
• Such a construction is advantageous because the weight saving (in contrast to known hydraulic pistons, which are heavy and expensive and cause problems when they remain on the vehicle and have to be uncoupled from the container) allows a high payload and the parked container can be coupled quickly drains a power supply under forced control, while in today's systems with plungers on the vehicle there is no possibility of conveniently unloading the container even when it is parked.
• a particular advantage of the invention is the use of at least one form-fitting guide, which preferably runs on the outer sides of the press plate, such as a chain drive or a toothed rack, because there is a positive guide along the displacement path of the clearing plate, so that it does not move laterally as a result of uneven propulsion can jam and the chain can be easily replaced when worn if the gears engaging in the chain / rack are rigidly connected to each other.
• the chain is advantageously laid on guide profiles (25) attached to the side of or in the container and can also be covered against contamination.
• Position 27 is the container floor
• position 28 is a known connecting element for fastening the container to the vehicle.
• the chain can also be provided with guide rollers in a known manner in order to increase the wrap angle on the drive sprocket. This leads to a better load distribution on teeth and chain links.
• the drive for the circulating chain is fixed, for example, on the vehicle side and is coupled to the chain after the container has been received. It is even possible to provide the drive unit (32) with a known quick-release fastener, for example, so that it can remain on the vehicle when removed from the container, while the container serves as a cheap storage option for the types of waste contained therein.
• the press plate can be moved by means of a cable drive according to FIGS. 4a, b, c.
• the drive can be designed in two parts so that a part remains firmly on the vehicle and the part remaining in the container in a known manner, for. B. is coupled by means of a coupling, stub shaft, socket, gear pair etc.
