LOCKING DEVICE

The invention relates to a locking device, in particular for the temporary locking of detachable downtimes 5 with possible lifting / lowering functions on swap bodies used in land and sea transport, i.e. the so-called 'swap body * structures. The invention further relates to a method for unloading said often non-standing cargo carriers from a truck or similar transfer device 10 to temporary standing legs or the like.

Swap bodies, or so-called The use of 'swap boots' as a transport unit has grown significantly in recent years. Compared to sea containers 15, user requirements have transformed these units into light-duty and cargo carriers that deviate from the mentioned container standards, especially in terms of lengths. 'Swap bodies' include container corner pieces or equivalent structures at standard positions in the substructure. Of said container corner pieces or the like, the cargo carriers are locked to their transport platform.

The base structure also has gripping areas on the sides, especially for the lifting arms, where the ‘swap body’ is usually lifted into or out of the car or other means of transport. In a long ‘swap body’, e.g. over 12 m, said infection areas are located; 25 according to the standard to the center of the carrier symmetrically. Short swap bodies, 7.82 m and smaller, generally include reversible stand legs on which the swap body can be left with a car equipped with a leveling device.

30 Longer swap bodies generally do not include downtime, but are emptied and loaded either connected to the car or on a loading platform on which they have been lifted by a large forklift truck or crane. Lifting can also take place conventionally with wire or chains but in practice it is rarely used as a cumbersome operation. In the case of long swap bodies, the transport platform is usually a semi-trailer coupled to a tractor, which is rarely equipped with a platform lift, so there is no precondition for lifting the swap body 2 80410 auto-assisted above the transport height and driving under the semi-trailer.

Since in the case of long swap bodies, these are 5 remarkably heavy cargo carriers, which, in addition, can only be lifted when loaded from certain points specified by the standard, the swap body is not usually detached from its transport platform today. This is due to the high cost and space requirements of heavy lifting equipment and the lack of alternative technologies.

Due to the above, the wheeled transport platform has to be parked as the platform of the swap body during the loading and unloading phase. In places where a loading dock is not used, said measures 15 are still difficult to carry out, because the cargo has to be moved first from the swap body to the ground level or vice versa.

In places where loading and unloading times are long, it is necessary to invest in expensive lifting equipment 20 to release road vehicles, or loading / unloading is carried out elsewhere with recourse to feeder traffic.

It should also be noted that detachable lifting and standing devices corresponding to the top and bottom corners of the container, which are known for handling a sea container, are not usable ·; 25 in the case of swap bodies, as these generally do not have upper corner pieces.

Although swap bodies provide substantial advantages over long journeys on international routes as well, the handling of the transmission and reception end of said swap bodies today involves the significant drawbacks described above which the present invention is intended to address.

.35 The device according to the invention and the method of handling swap bodies associated with its use provide a substantial improvement in the drawbacks described above. To achieve this, the device according to the invention is characterized by what is stated in the characterizing part of claim 1 3 80410. The most important advantage of the invention is that the swap body can be detached from its transport platform by means of technically and economically advantageous devices, which, if necessary, can also lower the swap body 5 to the ground for advantageous loading or unloading.

In the following, the invention will be explained in detail with reference to the accompanying drawing.

Figure 1 shows a locking device according to the invention from the side.

Figure 2 shows the same as Figure 1 but seen from above. Figure 3 shows a section of a locking device according to the invention connected to a swap body.

Figure 4 shows a side view of a swap body on a transport platform.

Fig. 5 shows the same as Fig. 4 but seen from behind and equipped with locking devices and standing legs according to the invention.

Fig. 6 shows the same as Fig. 5 but with the stage when the transport platform has been removed.

Figure 7 shows another locking device according to the invention in an axonometric view.

Figures 1 and 2 show a part of a replacement load basket 1, the base structure 2 of which has, according to the standard, container corner pieces 3 25 or similar structures and in their vicinity at positions defined by the standard for responses 4 with regard to lifting arm grip.

The locking device 5 according to the invention comprises, for example, a body part 6,7 made of steel plate and suitably bent 30 or otherwise known in shape, consisting of a container corner piece 3 or the like of a counter plate 6 and an organically associated support part 7 as a straight extension. inside the outer edge of the swap body 1, to which, on the other hand, the stop plate 6 corresponds at the container corner piece 3 or the like. Further, according to Fig. 1, the support part 7 is expediently slightly wider than the abutment plate 6. This is explained by the structure of the standard abutment 4, which is also shown in Fig. 3, which shows 4 80410 sections I-I in Fig. 2. The support part 7 can also be height-adjustable. This height adjustment compensates for any manufacturer-specific height differences between the container corner piece 3 and the stop 4 5 permitted by the standard.

The abutment plate 6 comprises the parts shown in Figures 1 and 2, namely: - a container lock 9 pivotally mounted via a lever 10 in a right-hand hole 10 in the abutment plate 6 where it can move axially - a nut 11 threaded into the container lock 9 and tightened by the lever 12 , by which the nut 11 adjusts the axial position of the container lock 9 in the abutment plate 6. The support part 7 comprises a sleeve 8 or the like for fastening one of the legs 15 shown below to the locking device 5.

In this connection, it should be noted that although the locking device 5 is shown to be attached to the legs via a sleeve 8 or the like, said legs may also be of such a construction that the locking device 5 is an integral part thereof.

Figure 3 shows the support of the support part 7 on the stop 4. A strip 13 is attached to the outer edge of the upper part of the stop 4 belonging to the base structure 2, for example by welding, which prevents. 25 according to the original use, the gripping members of the lifting arms in the lifting phase slipping out of the stop 4? likewise, the strip 13 also helps to prevent the support part 7 of the locking device 5 according to the invention from moving away from the stop 4 in the support situation.

The locking device 5 according to the invention is installed, for example, in connection with a replacement load basket 1 on a vehicle 14 as follows: - the locking device 5 is pressed against the container corner piece 35 3 or the like so that the container lock 9 presses in from the standard opening of the container corner piece 3. on the upper surface and inside the strip 13 to the position 5 80410 according to Fig. 3 - it is ensured with the lever 10 that the container lock 9 is in the locking position and the nut 11 is tightened with the lever 12 so as to lock the locking device 5 in position.

The purpose of locking the response plate 6 and thereby the entire locking device 5 by means of the container lock 9 is primarily to prevent the locking device 5 from protruding out of the plane of the base structure 2. The leg structures associated with the sleeve 8 effectively prevent the locking device 5 from turning around the container lock 9, i.e. from turning in a plane perpendicular to the plane 10 of the base structure 2.

The locking device 5 is preferably made of, for example, a 25-30 mm strong steel plate or a thinner plate with a suitable shape and profiles for stiffening and reinforcing. The construction dimensions of the sleeve 8 or the like are appropriately selected. Figure 4 shows a swap body 1 on top of a vehicle 14. The vehicle 14 is, for example, a semi-trailer without level lifting devices. In the method according to the invention, the replacement load basket 1 20 is dismantled from the above-mentioned vehicle 14 without a level lifting device as follows: - the locking devices 5 according to the invention are attached to the inner container corner pieces 3 of the replacement load body 1 and their adjacent stops 4? there will be two pieces on each side of the swap body 1. . Locking devices 5 according to the invention - as shown in Fig. 5, legs 15 comprising lifting devices 16 are connected to the sleeves 8 of the locking devices 5 according to the invention, as is known per se; the lifting devices 16 are preferably air springs powered by the vehicle 30 - when the locks of the swap body 1 securing its transport position have been removed from the vehicle 14, are lifted synchronously by the lifting devices 16 using the lifting devices 16 so that the swap body 1 rises slightly from the vehicle. 14 above the cargo level; in connection with the lifting operation, the leg 15,16 locks the support part in a lockable manner in connection with the stop 4 - after this the vehicle 14 can be driven away between the legs 15; the shape of the legs 15 is expediently chosen so as to allow a reasonable clearance between the leg 15 and the vehicle 14 - the swap body 1 can now remain on its legs 15 or, if desired, be lowered to the ground if the known structure of the legs 15 5 allows.

Figure 7 shows an alternative solution according to the invention. The abutment plate 6 'is rotatably connected to the sleeve tube 17 and is held in position by the sleeve 8' and the support part 7 ', which 10 are fixedly connected to the sleeve tube 17. The rotatable abutment plate 6 · allows the same construction to be used for all locking load car 1 locking points.

As previously mentioned, the locking device 5 according to the invention can be an integral part of the leg 15, whereby the connection of the leg 15 and the associated lifting devices 16 to the abutment plate 6 and the support part 7 can be solved in many other ways than described above.

As described above, a preferred detachable locking device 5 is implemented, to which a number of different standing and lifting times comprising functions known per se can be connected, or that said locking device can be an integral part thereof. Said locking device legs, which can be implemented technically and economically considerably compared to cranes and forklift truck solutions, are capable of unloading swap bodies from a vehicle in a crane-free and forklift-free small industrial and commercial environment.

Otherwise, it should be noted that the invention has been described above with reference to only one preferred embodiment thereof. However, this is not intended to limit the invention to this example only, but many modifications are possible within the scope of the inventive idea defined by the following claims.
