Description

Container vehicle

The invention relates to a container vehicle according to the preamble of the first claim.

When it comes to the movement of goods and goods, the importance of containers is in the has grown steadily over the past few years. Containers have the advantage that the to be transported Goods and goods can be loaded and unloaded without the actual transport vehicle Rather, the container is used for loading and unloading during this process deposited from the transport vehicle by means of a depositing device, after which the Transport vehicle, such as a truck, can be used for other tasks can.

For the purpose of lowering the container from the transport vehicle and there are a plurality of loading devices for mounting on the transport vehicle known. According to DE-PS 16 30 543, such a loading device has two to both Sides of the container arranged, pivotable in the respective pivot plane Piston-cylinder units, the upper ends of which form a joint and the lower ends Ends fixed on the one hand and movable on the other hand in relation to the frame, e.g. the Transport vehicle are articulated.

The lower ends of the piston-cylinder units are pivotable arranged on the frame and on this optionally lockable support rails zn. Between the joint and the middle of the loading area is an extendable support tube on both sides transversely arranged pivotably to the longitudinal axis of the vehicle. The support rails can according to the DE-AS 17 55 332 designed to be telescopic and extendable at their outer ends be provided with swiveling folding supports. The one placed on the transport vehicle Container is lifted with this crane-like direction in a circular Movement either onto another vehicle, a frame or directly onto the ground deposited so that the container is now to the side of the transport vehicle. The touchdown movement follows in the opposite direction.

Such loading devices are mechanically very complex and therefore expensive to manufacture and maintain. The invention is based on the object a simply constructed one for a container vehicle of the type in question Specify loading device with which the removal and placement of the container facilitates will.

This object is according to the invention by the characterizing Part of claim 1 specified features solved.

In contrast to known loading devices, the container is when Deposition initially only moved horizontally in the direction of the deposition location. Of the Container can, for example, be placed next to the car, e.g. a truck Frame are slidably transferred, with between the frame of the truck and the frame support rails are arranged and the container e.g. with the help a winch is pulled onto the frame. The setting up of the container from the Racking on the truck is done in the opposite direction. During the deposition and placement process therefore essentially only needs to overcome the frictional resistance of the container will.

This can be reduced, for example, by opening the container Rolling is running.

The frame for the container to be deposited can be a separate frame that is set up at the drop-off point, or one with the frame of the transport vehicle be connected frame, which either remains at the drop-off point or after supporting of the container on the floor can be removed.

The loading device preferably has a telescopic arrangement, which is firmly connected to the carriage frame. The container then rests during the Driving operation locked on a frame-like telescopic element. After propping the frame-like telescopic device can be extended while taking the container with it will. If the container is at the drop-off point, it is supported, after which the telescopic device can be retracted again and for picking up and putting down another container is ready.

However, it is also possible to use the frame-like telescopic device to design lowerable on the frame of the transport vehicle. Is the container then extended in the direction of the drop-off point, the supported telescopic device is then extended lowered until the container is supported on the ground. The telescopic device can then be retracted and raised to the starting position on the trolley frame.

A telescopic loading device according to the invention can be set down of containers to be used to the side of the transport vehicle when the direction of extension the telescopic device runs transversely to the longitudinal axis of the carriage frame. Wid the telescope arrangement swiveled so that the extension direction runs in the longitudinal direction of the carriage frame, in this way, a container can be placed directly behind the transport vehicle will.

A container vehicle with one designed in accordance with the invention Loading device can also be used for lightweight containers that come with usual crane-like loading devices, in which the container is hung, only under With the help of special constructions, generally our own hanging racks can be set down for containers and placed back on the transport vehicle. In a container vehicle according to the invention, forces are applied to the container due to the horizontal displacement movement only in the area of the stiffened Exercised on the base frame, but not on its superstructures.

Further refinements and advantages of the invention emerge from the subclaims in connection with the following description in which the invention is based on the drawing is explained in more detail. The drawing shows: FIG. 1 a plan view on a container vehicle with a loading device according to the invention, while lowering a container to the side of the vehicle; Figure 2 is a view of the Container vehicle and the remote container; Figure 3 is a perspective Representation of a loading device of the vehicle according to FIG. 1; Figure 4 is a view a charging device in a second embodiment according to the invention; Figure 5 is a perspective schematic view of a loading device according to another Embodiment of the invention and Figure 6 is a schematic Representation of a container vehicle with a loading device according to a fourth Embodiment.

In Figure 1 is a truck 1 with a long vehicle frame 2 shown, wherein the vehicle can accommodate two containers 3 on the frame are deposited one after the other. With the frame 2 of the vehicle is for each container a loading device 4 is provided, which is shown schematically in Figure 1 only for the front Container is shown and for setting down the container to the side of the vehicle serves.

The rear container 3 can be deposited with a similar loading device be, whereby this deposition preferably takes place in the longitudinal direction of the vehicle, so that the container is deposited behind the truck.

A loading device for setting down a container to the side is shown in FIG. It consists of a telescopic frame 5 of two transversely to the frame axis firmly connected to this profile struts 6, which are interconnected by a crossbar 7 are connected, as well as from two further rails 8 and 9, wherein the last profile rails 9 are in turn connected to one another by a cross strut 10 are. The profile rails 8 slide in the first firmly connected to the frame Profile rails 6, while the second profile rails 9 slide in the profile rails 8. The telescopic frame 5 can by means of a hydraulically operated cylinder arrangement 11 are retracted and extended, which with one end on the cross strut 7 and with the other end is connected to another cross strut 12, which is the front Connects ends of the two profile rails 9 to one another. The two profile rails 9 each have two supports 13 on which the container, not shown here rests. If the telescopic frame is retracted, it is at rest the container mi its lapping axis centrally above the vehicle frame 2 and is in this position locked by locking elements not shown here. The individual movable profile rail pairs 8 and 9 can be connected by further cross struts 14 and 15, so that they each form a solid framework. The four supports 13 on the profile rails 9 are each connected to a lifting cylinder 16, through which they are raised and lowered can be.

In the area of the front fixed profile rail 6 in Figure 3 is below of the frame, a cross member 17 is also provided, with which a foldable support 18 connected is.

To set down the container placed on the truck first pivoted the support 18 onto the ground, it being possible, as in FIG 3 shown in dashed lines that the support 18 can be extended laterally. Afterward the container is unlocked from the vehicle frame 2 and the cylinder assembly 11 actuated. The container, which rests on the supports 13, is when the Telescopic frame 5 shifted laterally. The downward weight of the container is caught by the support 18. Is the telescopic frame fully extended , the container is, as shown schematically in Figure 1, at the drop-off point.

The lifting cylinders 16 for the supports 13 are then extended, so that the container is raised slightly overall. With the container frame Support feet 19 can then be connected. The lifting cylinders 16 slightly retracted until the support feet 19 touch the ground and now the Carry container. By further retraction of the lifting cylinder 16, the supports come 13 out of contact with the container, so that the telescopic frame 5 can be retracted can. The support 18 is also connected folded back and possibly retracted. The container vehicle is then ready to receive a further container ready. A staircase 20 can also be used to load the container can be provided, as shown schematically in FIG.

Replacing the parked container on the truck takes place in reverse order, so that initially the support 18 is extended and is folded onto the floor, then the telescopic frame under the container 3 is driven, whereupon the lifting cylinders 16 are actuated and the container 3 is lifted. After removing the support feet 19, the container can then by pulling in the telescopic frame 5 can be transported on the Lastkrafbagen, where it is then locked. After folding in and possibly retracting the support 18, the container vehicle is ready for departure.

In Figure 4, a further loading device 4a is shown in side view, which in turn is designed as a telescopic frame 5a according to the above embodiment is.

The telescopic frame 5a in turn consists of three pairs of profile rails 6a, 8a and 9a, the profile rails 6a being firmly connected to the vehicle and the two other pairs of profile rails 8a and 9a can be extended and retracted telescopically are as described above. -In contrast to the above embodiment however, the telescopic frame 5a is arranged below the vehicle frame 2. in the When driving, the container rests with its bottom 41 on two Qaerträern 42, which are connected to the vehicle frame 2.

The container is locked by a bolt 43. In the bottom 41 of the Containers also engage with lifting cylinders 44 actuatable supports 45, as shown in Figure 4 for the already extended container 3 schematically is shown. The lifting cylinders 44 with the supports are in turn on the profile rails 9a attached.

If the container 3 is to be deposited from the container vehicle, so initially, as in the above embodiment, a lateral, not here shown support unfolded and then the locking of the container with the latches 43 released. Then the in the extension direction of the telescopic frame 5a rear support 45 retracted so that it is below the lower limit of the vehicle frame 2 come to rest. If the telescopic frame 5a is now extended, so the container, which is still with the front supports 45 with the profile rails 9a is connected. To support this entrainment movement, you can the cross members 42 may be provided with rollers 46 which support the bottom 41 of the container. As soon as the telescopic frame 5a is extended so far that the rear supports 45 are outside the frame, but the container 3 is still on the cross member 42 rests, the rear supports 45 are raised by means of the lifting cylinders 44 and again snap into the bottom 41 of the container. Then the telescopic frame 5a fully extended. The lifting cams 44 are still hydraulically operated Feet 47 connected, which are lowered to the ground when the telescopic frame is extended so that now the entire weight of the container 3 on these feet 47 rests. The container 3 has at its bottom 41 pallet feet 48, the given by the pallet feet 48 ground clearance between the lower end of the feet and the bottom 41 is chosen so that it is greater than the height of the telescopic frame 5a is. The pallet feet 48 are either permanently connected to the container or it will be relatively short when the container is extended Feet connected to this. If now the supports 45 by the hydraulic cylinder 44 are lowered, the pallet feet 48 or other support feet encompass the telescopic frame 5a and protrude downward beyond its lower limit.

The entire telescopic frame 5a can then be lowered. For this purpose, the two profile rails 6a of the telescopic frame 5a with the help of two Guide tubes 49 out, which can be lowered to the ground by means of hydraulic cylinders 50 are.

The hydraulic cylinders 50 are attached to the cross members 42.

One guide tube 49 is shown in two positions in FIG. where the dashed Darstelling the lowered guide tube time, while the solid position shows the drawn-in guide tube, which is the cross member 6a presses against the vehicle frame by means of plate feet 51.

If the guide tubes 49 have been moved down to the ground, so can the feet 47 are retracted on the profile rails 9a by means of the hydraulic cylinders 44 so that the entire telescopic frame sinks down. Since the weight of the Containers 3 rests on the feet 47, the rails 6a accordingly through the Weight of the container are not loaded, the telescopic frame 5a sinks evenly down to the ground. The telescopic frame 5a can now be under the stationary container be retracted; then the hydraulic cylinders 50 are actuated and lifted Return the entire telescopic frame 5a to the starting position shown in FIG below the vehicle frame 2.

The attachment of the telescopic frame 5a below the vehicle frame 2 has the advantage that the entire telescopic frame can only be lowered slightly must to set the container 3 down to the ground.

Part of a further loading device 4b is shown in FIG. This loading device has two transversely to the vehicle frame 2 and firmly with this connected cross struts 52 on which the container, not shown here rests while driving. To lock the container are not shown Locking elements provided.

With the front ends of the two cross struts 52 are parallel to Vehicle frame level pivotable Vedängerngsstreben 53 connected. The extension struts 53 each have two supports 54 in their area facing the free end on, in each of which a lifting cylinder 55 is integrated. The extension struts 53 are placed under the container resting on the cross struts 52 while the vehicle is in motion pivoted and locked in this position with bolts 56 on the frame or among each other.

To set down the container, the extension struts 53 are in the extension of the cross struts 52 pivoted, the free ends of the extension struts can still be connected by cross struts not shown here. The vehicle is, as described for the above exemplary embodiments, not yet with one here The lateral support shown is supported in accordance with the support 18. From the lift cylinders 55 feet 57 can now be extended to the ground so that the swiveled out Extension struts 53 form a solid frame for the container to be deposited. The container can then be unlocked, e.g. with the help of a cable winch be pulled onto the extension struts 53 until it is centered through the sand feet 57 is supported. It is possible to roll the container on the bottom to be provided, which then roll on the cross struts 52 and the extension struts 53, so that the resistance necessary for transfer to the deposition site is kept low will. For final withdrawal can as in the first embodiment be moved by the container on the lifting cylinder 55 with the supports 54 is raised, then support feet are attached to this and the container is lowered slightly. By further retraction of the supports 54 can then Extension struts 53 are pivoted back into the starting position. These Extension struts 53 can also be used in Art of telescopic rods, e.g. be built up from two profile rails each.

Another charging device 4c is shown in FIG. The container is mounted on cross members 61 on frame 2 of the container vehicle and locked with bolts 62. At the desired installation location for the person to be deposited Container 3, a frame 63 is set up, which via guide struts 64 with the ends of the cross members facing it 6-1 is connected. The container 3 can be equipped with rollers 65 to reduce the resistance when moving, which rest on the cross members 61. With the cross members 61 is still a winch 66 connected, the rope guided over pulleys 68 on the outer edge of the frame and is then hung on the bottom of the container at 69.

If the container 3 is unlocked and the winch is operated, then the container on its rollers 65 over the cross members 61 and the guide struts 64 drawn onto the frame 63. It can then be locked here. To Unhooking the rope 67 and removing the guide struts 64 is the container vehicle ready for the SuEnÇlme of another container. To load the container from the Frame 63 on the container vehicle is the rope 67 on the one facing the winch Suspended on the side of the container and again on the cross members via the guide struts 64 61 drawn.

Here it can be locked with the bolts 62 for removal.

This has been assumed so far in the case of the charging devices described has been that the container is unloaded sideways from the container vehicle; the However, after appropriate rearrangement, charging devices can also be used to unload the container behind the container vehicle. Such a construction is usually chosen for the rear container (Figure 1), as there is a side one Extending is often not possible due to the existing vehicle wheels.

With a container vehicle according to the invention, lightweight containers can be easily deposited and reloaded onto the container vehicle. The forces required for this are relatively small because the container is being transferred from the container vehicle to the storage location essentially through a horizontal one Sliding movement takes place.

The horizontal movement of the container can be hydraulic or also done by a simple winch; this second possibility is e.g. also for Extending the telescopic frame given according to the above embodiments. That The winch rope must then be guided accordingly over several pulleys To enable retraction and extension.
