Description

The invention relates to a self-propelled and self-loading and unloading loading system for containers or swap bodies, in particular for containers according to DIN ISO 668.

Self-propelled loading systems for containers are already known, which could also be used for swap bodies. For example, US Pat. No. 3,348,711 describes a carrier vehicle for u. a. Container whose trolleys are telescopic in height. However, this carrier vehicle is not self-propelled and nothing is said about the fact that it could automatically be loaded and unloaded onto another vehicle.

DE-Gbm 93 07 633.9 describes a device in which a U-shaped pick-up for a container can be telescopically moved together both in width and in length and height. This device is also not self-propelled and cannot be loaded and unloaded automatically onto another vehicle.

The object of the present invention is a loading system which, on the one hand, is self-propelled and, on the other hand, can be loaded or unloaded automatically onto a transport vehicle for a container or swap body without any external aids, so that a transport vehicle with a loaded loading system can be brought to any location and then Containers or swap bodies can be loaded and unloaded there, the loading system loaded onto the transport vehicle having no greater space requirement than a container loaded onto this transport vehicle.

• (b) a transport frame with ISO corners at its four upper corners and two lower cross-members provided with iso corners of the width dimensions of a container, wherein the transport frame has the length of a container and is of such a width and height that when driven over the transport frame and With this container lifting truck, which is in engagement via the retractable telescopic crossbars, the width and height of a container are not exceeded when the chassis units are swiveled in.

According to an advantageous embodiment, the loading system is characterized in that the transport frame consists of a lower frame part with two lower cross members, four hinged supports which can be locked in their end positions and which carry ISO corners at their upper ends are hinged to the frame part. This embodiment is advantageous because the transport frame can be produced with less material can and also takes up less storage space when not in use after the supports have been folded down.

In a further advantageous embodiment, the loading system is characterized in that the transport frame itself is provided as a walk-in container with fixed floor walls, side walls and ceiling walls. The advantage of this embodiment is that an additional weatherproof and lockable storage space for auxiliary equipment and / or for a temporary stay of operating personnel is available, which is available at any time together with the lifting truck for the container or the swap body.

In yet another advantageous embodiment, the loading system is characterized in that the transport frame is designed like a roll-off tipping container, as is specified in detail in the DIN 30722 standard. Such a roll-off container can, for. B. separated by means of the lifting elements and guide rails located on a transport vehicle and loaded independently of the container pallet truck on such a roll-off tipping vehicle.

In yet another embodiment, the loading system is characterized in that each undercarriage unit comprises three wheels, one of which is each non-steerable and driven and the other two wheels are steerable. The advantage of this embodiment lies in the fact that with this configuration, with a loading system for a so-called 20-foot container with dimensions of 6050 x 2700 x 2450 mm and a permissible total weight of 24 tons, the container pallet truck can be fitted with normal tires, whereas with only two wheels per chassis unit, special tires would be required. It is also advantageous to drive only the non-steerable wheels, since this is usually technically easier to carry out.

In a further advantageous embodiment, the height adjustment of the chassis units is carried out by hydraulically acting Twin cylinders, which move the guide tubes against each other, causes. This has the advantage that such a configuration is less expensive.

1 shows a perspective view of the loading system consisting of container pallet truck 1 and transport frame 9, which is loaded onto the trailer 15 of a transport vehicle, not shown, such as a semitrailer. The container pallet truck consists as essential components of the ceiling frame 2, which is attached to the long sides 6 and 6 ' Chassis units 5 and 5 'and the horizontal, telescopic trusses 3, which are retracted here. At their ends, these crossbeams 3 each have a receiving bolt 4 on a suitably designed flange, which is provided for engaging in upper ISO corners of both the transport frame 9 and a container to be accommodated - as will be explained below with reference to FIG. 2 . In Fig. 1, these locating bolts 4 are in engagement with the ISO corners 10 of the transport frame 9, as indicated in the right part of FIG. 1. The chassis units 5 and 5 'articulated on the longitudinal sides 6 and 6' of the ceiling frame 2 are in the pivoted-in state, ie closely fitting on the longitudinal sides 6 and 6 'of the ceiling frame 2. Furthermore, their wheels 14 are in the raised state, ie the total height of the loading system does not exceed the height of a container normally loaded on such a trailer. For this purpose, the height H of the transport frame 9 is selected in a suitable manner, ie the height H of the transport frame 9 plus the height of the ceiling frame 2 of the container lifting truck as well as possible distances between the two components should reach the maximum height of a container. In one or both undercarriage units 5, 5 ', the drive devices 7 for at least one wheel 14 are / are accommodated, depending on the space requirement, so that the container pallet truck is self-propelled either alone or with the associated transport frame 9. The components required for this are not shown in detail since they are familiar to the person skilled in the art. These drive means can e.g. B. in the case of electric or hydraulic drive also to operate the telescopic height adjustment of the chassis units and / or the horizontal telescopic trusses 3. The actuating devices for these traverses 3 are not shown in detail; these can be mechanical or hydraulic servomotors and actuators. The traverses 3 must on the one hand be able to be retracted until they engage the ISO corners 10 of the transport frame 9, and on the other hand can be extended so far that they can be brought into engagement with the ISO corners 10 of a container to be accommodated - see Fig. 2. The total width of the container truck 1 when the chassis units 5 and 5 'are pivoted in - as shown in Fig. 1 - should not exceed the width of a container, ie the width B of the transport frame 9 must be selected so that it Width B plus the additional widths of the two undercarriage units 5 and 5 'and any necessary intermediate distances do not, or only slightly, exceed the width of a container so that the permissible width of a road transport vehicle is not exceeded when the loading system is loaded on a transport vehicle.

FIG. 2 shows a perspective view corresponding to FIG. 1, but here the trailer 15 is omitted and instead of a transport frame 9 there is a container C under the container lifting truck 1 that has been moved over it. The chassis units 5 and 5 'are shown in the pivoted-out state. This swiveling takes place via the swivel parts 18 actuated by means of lifting cylinders 17, on which the telescopic device 8 for the chassis unit 5 engages. After retracting these telescopic devices and thus lowering the container pallet truck, the connection of the container C with the container pallet truck can be achieved by retracting the trusses 3 and latching the locating bolts 4 into the upper ISO corners 10 of the container C.

FIG. 3 is a representation corresponding to FIG. 2, in which a container C 'has only lower ISO corners 10 and engagement devices 4' are provided on the crossbeams 3 of the container lifting truck 1 in order to hang the auxiliary carrying devices 21 and 22 to be able to whose lower parts can then be hung in the lower ISO corners 10 of the container C '. With 19 and 20, the steering and leveling of the wheels 14 are designated.

The transport frame 9 is shown in detail in FIG. 4. At its four upper corners, it comprises the ISO corners 10 and the two lower cross members 11, which are the width of a container have so that they can be used in the complementary receptacles for a container on a transport vehicle. In this way, a loading system consisting of container pallet trucks 1 with a transport frame 9 underneath, as shown in FIG. 1, can be easily anchored on a transport vehicle, as shown in FIG. 1.

Fig. 5 shows another embodiment of a transport frame 9 ', in which four foldable and lockable supports 13 are provided which engage a lower frame part 12.

Fig. 6 shows a further embodiment of a transport frame 9 '', which is provided with side, floor and ceiling walls and a door, so that it also provides its own container or container for receiving additional devices or for the stay of operating personnel.

FIG. 7 shows yet another embodiment of a transport frame 9 '' ', which is designed like a so-called roll-tilt container according to DIN 30722, for which purpose it has the roller rollers 23 and the receiving bracket 24.

8 is a sectional view of a hydraulic twin cylinder for actuating the telescopic device 7 of the undercarriage units 5 and 5 'according to FIGS. 1 to 3. It includes the three guide tubes 25 belonging to the telescopic device and the twin cylinders 16 arranged within these guide tubes 25 with the associated ones Supply lines 26 for hydraulic fluid. The twin cylinder 16 is double-acting, that is, it can cause both a forced extension and a retraction of the chassis units 5 and 5 ', corresponding to a lifting of the container lifting truck 1 when unloading from a transport vehicle or lifting a container located under the container lifting truck or transport frame.

When used, the loading system according to the invention has the advantage that it can be used with a transport vehicle, e.g. B. a semi-trailer with associated trailer, which is equipped to accommodate containers or swap bodies, can be transported in a compact form on this transport vehicle without exceeding the dimensions and regulations permitted for transport on roads. At the desired location, the container pallet truck can then automatically. H. without the aid of additional devices, by swiveling the two-sided undercarriage units and extending the telescopes with their wheels on the ground and raised enough by this, the respective anchoring of the transport frame to the transport vehicle via the four ISO corners of the crossbeams of the transport frame and the bolts have been loosened on the transport vehicle beforehand and the bolts of the horizontal crossbeams of the container lift truck remain in engagement with the ISO corners of the transport frame. In this way, the container lifting truck also lifts the transport frame and can move it away from the transport vehicle and set it down at any location. The connections between the transport frame and horizontal trusses can then be removed by extending the trusses, so that the container pallet truck is unloaded and can drive over the transport frame, so that it is free for receiving containers. After taking containers by appropriate extension and retraction of the telescopic horizontal traverses and locking their bolts into the ISO corners, this container can then z. B. can be moved or loaded onto any transport vehicle, or containers can be unloaded from other transport vehicles, for which purpose the free container pallet truck is driven over the container on the transport vehicle and the process of anchoring containers with the container Pallet truck is made over the trusses or ISO corners.

In the loading system according to the invention, devices known in the art can of course be used, e.g. B. can drive the wheels of the chassis units via electric motors, internal combustion engines or hydraulic motors, which Swiveling devices of the chassis units can be operated electrically or hydraulically and the devices for telescoping the chassis units can also be operated by electric motors or hydraulically via hydraulic cylinders. So-called hydraulic twin cylinders are advantageously used as devices for telescoping the undercarriage devices, as are shown in more detail in FIG. 8. The necessary units such as motors, accumulators, fuel storage tanks, etc. - both for self-driving the container lifting truck and for driving the horizontal telescopic trusses and for swinging out and in as well as telescoping the undercarriage units - can e.g. B. in one or both of the chassis units, as shown in Fig. 2. Sufficient storage space can also be provided in one of the undercarriage units in order to accommodate the auxiliary carrying devices that may be required for swap bodies or containers that are only provided with lower ISO corners or other receiving devices such as eyelets.

In the loading system according to the invention, the width of the ceiling frame and the width of the transport frame are advantageously the same. With a corresponding design and attachment of the horizontal telescopic trusses on the ceiling frame of the container truck, these width dimensions can also be different. It is only necessary that the width of a container is not exceeded when the container pallet truck is moved over the transport frame and after its connection to the transport frame and swiveling in the chassis units, so that a transport vehicle with a loaded loading system remains suitable for road use. The same naturally also applies to the height dimensions of a loading system loaded on a transport vehicle. By retracting the telescopes on the chassis units to the maximum height of a container, the loading system only has the dimensions of a conventional container, which is otherwise provided for transportation on such a transport vehicle.
