The invention relates to a coupling adapter for connecting transport systems for heavy loads.
For the transport of heavy loads, ie goods with a weight of 10 tons or more, different transport systems are used. As a rule, the load is lifted onto a heavy-duty loading platform with or without its own wheel axles, such as a so-called flatrack, a cargo trailer, a multi-axle chassis or a rail or roadworthy trailer or goods wagon, and then secured on this loading platform. This loading platform is connected to a vehicle with its own drive, for example with an industrial truck such as a forklift truck or heavy duty forklift on factory premises, a semi-trailer, a tractor, a RORO tractor, a harbor tractor, a stationary or mobile crane or a track or rail-bound traction vehicle ,
Along a transport path of the load, this usually has to be loaded several times from one loading platform to another loading platform. For this purpose, the load must be unlocked and lifted from a first loading platform, placed on a second loading platform and secured on this again, which increases the duration and cost of such a heavy load transport. In addition, there is always a risk of damage to the cargo (the load) or one of the transport systems used, such as one of the above-mentioned loading platforms or one of the above vehicles or hoists in such a transhipment.
It is therefore the object of the present invention to propose a solution to the difficulties described. Thus, the invention should make it possible to accelerate and reduce the transport of a heavy load and at the same time to reduce the risk of damaging the load or one of the transport systems used.
This object is achieved by a coupling adapter for connecting transport systems for heavy loads according to the main claim. Further developments result from the subclaims.
In a coupling adapter according to the invention for connecting transport systems for heavy loads, it is thus provided that the coupling adapter has a base element with a front side, on which at least one of the
The following coupling elements are arranged:
- A coupling arm for insertion into a coupling jaw,
- A coupling jaw for receiving a coupling arm and at least one of the following further coupling elements being arranged on at least one further side of the base element, in particular on a rear side of the base element facing away from the front side, on an upper side of the base element or on an underside of the base element:
- Another coupling arm for insertion into a coupling jaw,
- Another coupling jaw for receiving a coupling arm,
- A bolt tab coupling,
- A heavy lifting eye or a heavy load hook and / or
- - a twistlock element.
In the case that a coupling arm is arranged on the front side of the base element of the coupling adapter according to the invention, the coupling adapter has the suitability of a transport system, such as a loading platform, having a coupling jaw on a front side or a rear side for receiving this coupling arm, with different vehicles, possibly different manufacturers, with or without their own drive to connect, ie to couple to this. For this purpose, the coupling adapter on at least one of the above-mentioned further coupling elements on a further side of the base element. In addition to a cheapening and acceleration is achieved by the coupling adapter greater flexibility in the use of transport system from different manufacturers, as with the help of the transport system compatibility with different transport systems of different manufacturers can be produced, especially between transport systems of the manufacturers Mafi, Scheuerle, Goldhofer and Kalmar. Reduction of costs and
Loading platforms with Kupplungsmäulern for receiving a coupling arm, in particular a so-called gooseneck, are from the document DT 1 297 999
known and widely used as transport systems for heavy loads. Typically, they are coupled and moved by means of tractors or forklifts with a corresponding gooseneck attachment. The loading platforms shown in the cited document are designed as a mobile loading platform with axles. Of course, corresponding non-mobile embodiments of this loading platform without wheel axles are also possible. Accordingly, it is also possible in principle to equip a flatrack on a front side or on a back side (or on the front and the back side) of the flatrack with such coupling mouths.
The coupling of two transport systems via a coupling arm and a coupling jaw has proven to be very advantageous in practice, since it can be quickly and easily produced and released, very safe and suitable for heavy loads.
Depending on the specific embodiment of the further coupling element, a coupling of the loading platform with different transport systems can be carried out. Thus, it is thus advantageously possible to move a load located on the loading platform with different vehicles whose coupling systems differ from one another without having to transfer the load to another loading platform. In this case, only the coupling adapter has to be exchanged for another coupling adapter whose further coupling element, for example on the rear side of the base element, fits the coupling system of the vehicle used, for example a bolt tab coupling, another coupling arm or twistlock elements on the rear side of the base element of the coupling adapter , It is also possible that at the top of the base member coupling elements, such as a heavy-duty eyelet is arranged. In this way, the loading platform (generally the transport system) can be about a crane and lift. In one embodiment of the coupling adapter according to the invention in each case a coupling arm or a coupling jaw is provided at the front and at the rear of the coupling adapter. In the first case, the coupling adapter can be used, for example, to connect two of the loading platforms described above. In the second case, the coupling adapter can be used to connect two coupling arms, which are attached to approximately two suspensions. Of course, these two coupling arms can of course also be parts of a coupling adapter described here type. It is therefore possible, if necessary, to connect a plurality of the coupling adapters according to the invention with each other, so to speak, to switch them one behind the other, as a result of which the flexibility of the transport system used can be further increased.
Usually, the coupling arms used have a length in a range between about 0.3 m to 1.0 m. In one embodiment of the coupling adapter is therefore provided that a coupling arm of the coupling adapter has a length in a range between about 0.3 m to 1.0 m or that a coupling jaw of the coupling adapter has a depth in a range between about 0.3 m to 1 , 0 m.
In a further embodiment it is provided that in each case at least one side arm is arranged on a left side surface and on a right side surface of the base element for contacting side surfaces of a loading platform (or other transport system) connected to the coupling adapter. In this way, the stability and a maximum load of the clutch adapter can be increased. This is further increased in a further development, in which twist-lock elements are arranged on inner surfaces of the side arms, which are connectable to corresponding twist-lock elements on a loading platform.
In one embodiment, it is provided that, if no coupling jaw is provided, a length of the base member between about 5 cm and 50 cm, and if two Kupplungsmäuler are provided, the length of the base member is between about 0.8 m and 2 m. In this case, the length of the base element is defined as the distance between the front side and the rear side of the base element. In this way, in the case that two suspensions are coupled together, set an axial distance to about 1.4 m to 1.7 m.
By adjusting the relative vertical arrangement of the coupling elements on the front and the back of the base element height differences between interconnected transport systems, in particular loading platforms or chassis, can be targeted. Thus, for example, a height of a gap between a loading platform and a subsoil (eg a road) can be specifically adapted to local conditions or traffic regulations. It also dissolves in this way, a first suspension relative to a second, with the first connected via the coupling adapter lift, so that, for example, have one or more axles of the second suspension no contact with the ground.
In one exemplary embodiment, it is provided that the base element has at least one passage opening which passes through the base element from the front side to the rear side, for passing a support arm of a loading platform or another transport system through the passage opening. In this way, a connection between the coupling adapter and the transport system can be significantly increased.
In a further embodiment, it is provided that the base element has a coupling arm, which is fixed in height adjustable on the base element. In this way, differences in height between interconnected transport systems, in particular loading platforms or trolleys, set specifically, so that the advantages described above can be achieved. A corresponding height adjustment can be achieved, for example, that an intermediate plate is provided with a the front side facing the coupling arm and a rear side facing away from the front side, which is connected in a height-adjustable manner via connecting elements to the front side of the base element. Preferably, holes are provided at different heights in the intermediate plate and in the base member, which can be connected by means of pin-shaped or bolt-shaped connecting elements at different heights. If passage openings are provided in the base plate for the passage of support arms of a loading platform or another transport system, then appropriate passage openings are optionally arranged on the intermediate plate. Typically, the through openings in the base member are required at a greater height to allow passage of the support arms at different height adjustments of the intermediate plate relative to the base member.
In one embodiment it is provided that a first coupling arm are provided on the front side of the base element and a second coupling arm is provided on the rear side of the base element, wherein the first coupling arm can be arranged vertically offset relative to the second coupling arm. In a further embodiment, a first coupling jaw is provided on the front side of the base element and a second coupling jaw is provided on the rear side of the base element, the first coupling jaw in turn being arranged vertically offset relative to the second coupling jaw. In this way, the aforementioned coupling mouths can be guided past one another in an interior of the base element. This can serve, for example, to achieve a predetermined center distance between two interconnected running gears.
In a further development, it is provided that a width of the front side of the base element and / or a width of the rear side of the base element are in a range between 1.5 m and 2.8 m. On these can be said pages to adapt to a width of a loading platform (or generally a transport system) to achieve the largest possible contact area between the coupling adapter and the loading platform for a stable coupling possible.
For a coupling which is as stable as possible, it is further provided in an embodiment that twist-blocking elements are arranged on the front side and / or on the rear side of the base element, which are connectable to correspondingly corresponding twistlock elements on a transport system. In a further development, it is provided that the base element has a coupling arm on which at least one extendable securing bolt is arranged for securing or locking the coupling arm within a coupling jaw. Additionally or alternatively, at least one bulge or at least one indentation can be arranged on the said coupling arm for securing the coupling arm within a coupling jaw.
