Description

[0001] The invention relates to a tilting device for a drop-down container, which has tilting arms arranged at a distance from one another, each pivotable about a joint, wherein at each end of the tilting arms facing away from the corresponding joint a receptacle for the drop-down container is provided, into which receiving elements of the container can be received.

[0002] Such a tipping device and a transport vehicle using it, in particular a heavy-duty transport vehicle such as a transport vehicle for a metallurgical transport container like a slag bucket, referred to in technical language as a "slag transporter," are known from DE 299 15 549 U1 and DE 100 08 637 A1. These documents each describe a transport vehicle for a transport container which has the tipping device described above at its rear end (in the direction of travel). Each of the two tipping arms of the known tipping device is attached to the frame of the transport vehicle via a joint, and devices such as hydraulic cylinders are provided to enable a tipping movement of the two tipping arms. At the ends opposite the joint, each of the two tipping arms has a receptacle through which the container to be transported can be inserted into the tipping device.Typically, receiving claws are used for this purpose, which pick up transport pins that protrude diametrically from the container.

[0003] The loads that the known tipping device has to handle are very high, especially in the metallurgical sector; loads of more than one hundred tons are quite common. This means that the tipping device and the container being transported must be precisely matched to each other in order to safely handle and transport such loads. The tipping device is therefore usually designed for exactly one single container geometry or, at best, for very similar container geometries. In particular, the distance between the two tipping arms is designed for the diameter of the container being transported, since the distance between the outer wall of the container and the lifting jaws should be as small as possible to avoid undesirable bending moments that would otherwise act on the transport pins.On the other hand, there must be a sufficiently large space between the outer wall of the container and the inside of the tipping arms to ensure easy lifting, swiveling, setting down, and, if necessary, emptying of the container held in the tipping device of the transport vehicle. For the aforementioned reasons, it has therefore generally not been possible until now to hold different containers, especially containers with different diameters, in one and the same tipping device.

[0004] Users of such tipping devices, as well as transport vehicles equipped with them, increasingly require the ability to transport containers with a smaller diameter than that for which the tipping device was designed, not least for cost reasons. Extending the container's transport pins is not a viable solution for the aforementioned reasons, as this would increase the distance between the points where the transport pins attach to the container's outer wall and the tipping device's receiving claws, resulting in high bending moments acting on the transport pins.

[0005] It is therefore an object of the present invention to further develop a tilting device of the type mentioned above in such a way that it can accommodate at least two containers with different geometries, in particular with different spans. It is also intended to provide a transport vehicle that is particularly suitable for this purpose.

[0006] This problem is solved by the tilting device according to the invention in that at least one tilting arm of the tilting device has a receiving unit movably arranged on it, by which the distance between the receiving points of the tilting arms, in particular in the axial direction of the tilting device, can be changed from a first receiving distance of the tilting device to at least one further receiving distance.

[0007] The transport vehicle according to the invention is characterized in that the tipping device is designed as defined above.

[0008] Further advantageous embodiments of the invention are the subject of the dependent claims.

[0010] The Fig. Figure 1 shows an embodiment of a transport vehicle, generally designated by 1, with a first embodiment of a tipping device 10. Such a transport vehicle 1 is known per se and will therefore only be described below to the extent necessary for understanding the design and operation of the tipping device 10. The transport vehicle 1 has a drive unit 2, which is connected to a vehicle frame 3. The vehicle frame 3 supports a driver's cab 4. In the embodiment shown here, the vehicle frame 3 is designed as a U-shaped frame, in the free interior of which the container B1 to be transported by the transport vehicle 1 can be accommodated. Such transport vehicles designed according to a so-called "U-frame design" are known.However, it is evident to the expert from the following description that the exact design of the transport vehicle 1 is not important; the transport vehicle 1 can, for example, also be designed as a so-called "platform transporter" on whose platform the container B1 is placed.

[0011] The tipping device 10, attached to the vehicle frame 3, has two tipping arms 11a and 11b, of which in Fig. 1 Only the left-hand tipping arm 11a in the direction of travel is visible. The second tipping arm 11b is designed accordingly, as can be seen from the Fig. 3a and Fig. As can be seen in Figure 3b. Each tipping arm 11a, 11b is pivotably connected to the vehicle frame 3 at its first end via a joint 12. An actuating device 13, designed in this case as a hydraulic cylinder 14, serves to pivot the tipping arms 11a, 11b. The first end 14' of the hydraulic cylinder is attached to the vehicle frame 3, and its second end 14'' is attached to each tipping arm 11a, 11b. Extending and retracting the piston rod of the hydraulic cylinder 14 causes the tipping arms 11a, 11b to pivot about the joint 12. At its second end opposite the joint 12, each tipping arm 11a, 11b has a receptacle 20 through which the container B can be received in the tipping device 10. Such a design is known and therefore does not require further explanation.

[0012] Before explaining the function and design of the tipping device 10 and in particular the receiver 20, the basic structure of two containers B1 and B2, which have different diameters when viewed in the axial direction of the tipping device 10, will be explained using the figures for the sake of simplicity. However, the tipping device 10 is designed in such a way that both the larger container B1 and the smaller container B2 can be transported with the described tipping device 10.

[0013] The Fig. 2a and Fig. Figure 2b shows a first container B1, which here is designed in a bucket shape and is used, for example, in the field of metallurgy for transporting molten metal or slag. It will be evident to those skilled in the art from the following description that the exact shape of the container B1 is not critical; a bucket-shaped design is therefore not mandatory. With the described tipping device 10, cuboid containers, such as those used in dump trucks, can also be used. The container B1 has, in a manner known per se, receiving elements 15a, 15b projecting diametrically from its outer wall, which in this case are designed as receiving pins. The container B1 can be received in the tipping device 10 via these receiving elements 15a, 15b by inserting its receiving elements 15a, 15b into the receptacles 20 of the tipping arms 11a, 11b of the tipping device 10. As can be seen from the Fig. As can be seen in Figure 2b, the first container B1 has a span D. In order to be able to receive the container B1 in the tipping device 10, it is necessary that the distance between the two tipping arms 11a, 11b corresponds to the span D of the container B1, i.e., that the supports 20 have a distance from each other corresponding to the span D of the container B1.

[0014] The Fig. 3a and Fig. Figure 3b now shows a second container B2, which is essentially designed like the first container B1. As can be seen from the Fig. As can be seen in Figure 3b, the second container B2 has a span d that is smaller than the span D of the first container B1. Such a second container B2 could not previously be accommodated in the known tipping devices 10, since – as explained at the outset – the design of the tipping devices 10 had to be adapted to the geometry of the containers B1 and B2 to be transported.

[0015] In order to be able to transport containers of different spans with the described tipping device 10 and thus with the transport vehicle 1 using this tipping device 10, in the case shown here both the first container B1 with a span D and the second container B2 with a span d, the following configurations of the mounts 20 are provided for the tipping device 10.

[0016] All the embodiments described below have in common that the tilting device 10 is designed such that the distance between the receptacles 20 of the two tilting arms 11a, 11b in the axial direction of the tilting device 10, i.e., the receptacle width of the tilting device 10, is variable, so that by changing this distance the receptacle width of the tilting device 10 can be adapted to the span D or d of the respective container B1 or B2 to be accommodated. The receptacles 20 of the two tilting arms 11a, 11b can therefore be moved closer together or further apart in the described tilting device 10, so that the receptacle width of the tilting device 10 can be adapted to the span D or d of the respective container B1 or B2 to be accommodated.

[0017] This advantageous adjustability of the receiving width of the tipping device 10 is achieved in the described tipping device 10 by the fact that the receiving claws 20 of the tipping arms 11a, 11b are not designed – as in known tipping devices 10 – as fixed receiving claws rigidly connected to the tipping arms 11a, 11b or as an integral part thereof. Instead, the receiving claws 20 are movably arranged on the tipping arms 11a, 11b, so that a corresponding adjustment movement of the receiving claws 20 allows for the aforementioned change in the receiving width of the tipping device 10 and thus an adaptation to the diameter of the respective container B1 and B2 to be received.

[0018] In the Fig. 4a, Fig. 4b and Fig. 5a, Fig. In the first embodiment of the tilting device 10 shown in Figure 5b, it is provided that a rotatable receiving unit 21a, 21b, as shown in the figures, is provided at each of the two receiving ends of the tilting arms 11a, 11b as a receiving unit 20. Fig. 6a and Fig. The arrangement is shown in 6b and described in more detail below. Fig. 4a and Fig. Figure 4b shows the tilting device 10 together with the first container B1 with the larger span D and the Fig. 5a and Fig. 5b the same tipping device 10 with the smaller container B2, which has the smaller span. The receiving unit 21a provided at the receiving end of the two tipping arms 11a, 11b in the first embodiment is in the Fig. 6a and Fig. 6b is shown, where the Fig. 6a the receiving unit 21a in its working position for transporting the first container B1 and the Fig. Figure 6b shows the receiving unit 21a in the working position as it is used when transporting the second container B2. Each of the two receiving units 21a, 21b is rotatable about a bearing axis 19 of the tilting device 10, which runs parallel to the axis of rotation defined by the receiving elements 15a, 15b of the respective container B1 or B2 to be inserted. In the “normal” driving operation of the transport vehicle 1, this axis of rotation of the two receiving units 21a, 21b therefore runs in a horizontal direction and orthogonal to the longitudinal axis of the transport vehicle 1.

[0019] Before we begin with the Fig. 4a, Fig. 4b and Fig. 5a, Fig. 5b the function of such a tilting device 10 is described, is shown by means of the Fig. 6a, Fig. Section 6b describes the geometric-constructive structure of recording unit 21 and recording unit 21a. The structure of the second recording unit 21b is then corresponding.

[0020] The receiving unit 21a comprises a first receiving claw 22a and a second receiving claw 22b as receiving elements, which are preferably arranged on a common base body 23 of the receiving unit 21a and are further preferably formed as integral components of this base body 23. An opening 24 is arranged in the base body 23 through which the bearing axis 19 can pass, so that the receiving unit 21a can be rotatably attached to the tilting arm 11a as described above. The first receiving claw 22a of the two receiving units 21a, 21b serve—as described below—to receive the first container B1, which has a larger span D, while the second receiving claw 22b serves to receive the second container B2, which has a smaller span d.As can be seen from the aforementioned figures, the second receiving claw 22b is not arranged in the plane of the first receiving claw 22a, but is offset inwards in the axial direction of the receiving unit 21a, i.e., in the direction of the bearing axis 19. The distance between the first receiving claw 22a and the second receiving claw 22b is approximately half the difference between the first receiving width of the tipping device 10 required for receiving the first container B1 and the smaller second receiving width required for receiving the second container B2. When the first receiving unit 21a is mounted on the tipping arm 11a and the second receiving unit 21b is mounted on the second tipping arm 11b, and the two receiving units 21a, 21b are in their respective positions... Fig. In the position shown in 6a, the distance between the two receiving units 21a, 21b corresponds to the first receiving width of the tilting device 10. If the two receiving units 21a, 21b are then rotated about the bearing axes 19, so that the receiving units 21a, 21b are in their Fig. When the second working position shown in Figure 6b is reached, the distance between the two receiving claws 22b of the receiving units 21a, 21b is essentially equal to the second receiving width of the tipping device 10. Due to the design of the receiving units 21a, 21b described above, with receiving claws 22a, 22b offset from each other in the axial direction, and the corresponding movable arrangement of the receiving units 21a, 21b on their tipping arms 11a, 11b, it is thus possible in a simple manner to receive both the first container B1, which requires the first receiving width of the tipping device 10, and the second container B2, which requires the smaller second receiving width of the tipping device 10, in one and the same tipping device 10. This will be illustrated below with reference to the Fig. 4a, Fig. 4b and Fig. 5a, Fig. 5b explains:

[0021] The Fig. 4a, Fig. Figure 4b shows the tilting device 10 together with the first container B1, i.e., the container with the larger span D, in the first and second working positions of the receiving units 21a and 21b, respectively. The two receiving units 21a and 21b are arranged on the two tilting arms 11a and 11b such that the first container B1 can be received in the tilting device 10 in a manner known per se and therefore not described in detail here, by inserting the receiving elements 15a and 15b into receiving openings 25a of the first receiving claws 22a. When the two receiving units 21a and 21b are in this first working position, the tilting device 10 has—as described above—a first receiving width that is matched to the first container B1 with span D.

[0022] To accommodate the second container B2, which has a smaller span d than the first container B1, in the tilting device 10, the two receiving units 21a, 21b are each rotated about their bearing axis 19 until the second receiving claws 22b are in a position suitable for receiving the second container B2, in which the receiving elements 15a, 15b of the second container B2 can be inserted into receiving openings 25b of the second receiving claws 22b. Since – as described above – the second receiving claws 22b of the two receiving units 21a, 21b are arranged offset inwards in the axial direction of the two receiving units 21a, 21b, the tilting device 10 then has a smaller receiving span compared to the first position of the receiving units 21a, 21b, which is adapted to the second container B2.

[0023] The above-described design of the receiving units 20 of the two tipping arms 11a, 11b of the tipping device 10 thus makes it possible in a simple way to change the receiving width of the tipping device 10 by a corresponding movement of the receiving units 21a, 21b, so that the first container B1 with a span D and the second container B2 with a smaller span d can be received in one and the same tipping device 10.

[0024] The switching process between the first recording width and the second recording width of the tilting device 10 is schematically described in the sequence of Fig. 7a to 7f are shown. In the Fig. 7a The receiving units 21a, 21b of the receiving units 20 of the tilting arms 11a, 11b are in their first working position. It can be seen from the Fig. Figures 7a to 7c clearly show that in this first working position, the first receiving claws 22a are located on the outside when viewed axially. In this first position, the receiving units 21a, 21b are secured against rotation on the two tilting arms 11a, 11b. For this purpose, each tilting arm 11a, 11b has a corresponding anti-rotation device 70, which ensures that the receiving units 21a, 21b are fixed in a defined position on the tilting arms 11a, 11b. Such an anti-rotation device 70 can be designed, for example, by providing each tilting arm 11a, 11b with a hydraulic cylinder 71 whose piston rod (not shown) can be extended axially and thereby enters a locking opening 26 of the respective receiving unit 21a, 21b.

[0025] If the tipping device 10 is now to be prepared for receiving the second container B2, the locking mechanism of the two receiving units 21a, 21b, which are rotatably attached to the tipping arms 11a, 11b, is released, as shown schematically in the Fig. 7b and Fig. Figure 7c is shown. In the embodiment described here, the piston of the hydraulic cylinder 71 is withdrawn from the opening 26 of the two receiving units 21a, 21b, so that each of the two receiving units 21a, 21b can be rotated about its bearing axis 19. The two receiving units 21a, 21b are then – as shown in the Fig. 7c to 7e shown - pivoted about these bearing axes 19, so that - as in Fig. Figure 7f shows that the second receiving claws 22b of the two receiving units 21a, 21b are ultimately in this second working position of the tipping device 10 in the receiving position suitable for receiving the second container B2. After the two receiving units 21a, 21b have again been connected to the tipping arms 11a, 11b in a rotationally secure manner by inserting the piston rods of the hydraulic cylinders 71 into a further opening 26a of the receiving units 21a, 21b, the tipping device 10 is ready to receive the second container B2.

[0026] In the first embodiment described above, it was assumed that each receiving unit 21a, 21b has two receiving claws 22a, 22b, so that two different receiving widths of the tilting device 10 can be achieved by a corresponding rotation of the receiving claws 22a, 22b. However, it is also possible that the receiving units 21a, 21b, which are rotatable about the bearing axes 19, have more than two receiving claws 22a, 22b, so that the tilting device 10 equipped with the described receiving units 21a, 21b can be adjusted to more than two different receiving widths. Fig. Figures 8a to 8c show such an embodiment of the receiving units 21a, 21b, wherein the receiving unit 21b arranged on the second tilting arm 11b is shown in the aforementioned figures. The construction of the first receiving unit 21a is then corresponding. It can be seen from the aforementioned figures that the receiving unit 21b now has three receiving claws 22a-22c, which are arranged spaced apart from each other in the circumferential direction. Fig. Figure 8a shows the receiving unit 21b in its first working position, in which the two receiving units 21a, 21b form a first receiving width of the tilting device 10: The first receiving claw 22a of the receiving unit 21b is located – viewed axially – further outwards than the second receiving claw 22b and the third receiving claw 22c, so that the largest receiving width of the tilting device 10 is formed. If the receiving units 21a, 21b are now moved about the bearing axes 19 into their Fig. In the position shown in Figure 8b, in which the receiving units 21a, 21b assume their second working position for receiving the second container B2, the distance between the second receiving claws 22b of the two receiving units 21a, 21b corresponds to the second receiving width of the tilting device 10, which serves to receive the second container B2 (as described above). A further rotation of the receiving units 21a, 21b then brings the third receiving claws 22c, located furthest inwards in the axial direction, into the resulting third working position of the tilting device 10, so that a receiving container with a smaller span than that of the second container B2 can be received in the tilting device.

[0027] In the Fig. Figures 9 to 11b show a second embodiment of the tilting device 10, in which corresponding components are provided with the same reference numerals and are not described again with regard to their construction and function. Fig. 9a and Fig. Figure 9b again shows the tipping device 10 together with the first container B1, which Fig. 10a and Fig. 10b the tipping device 10 with the second container B2 and the Fig. 11a and Fig. 11b Receiving units 31a, 31b of the second embodiment, which correspond in their basic function to the receiving units 21a, 21b of the first embodiment, namely that, by means of a corresponding design and movable arrangement on the tilting arms 11a, 11b, the receiving width of the tilting device 10 can be changed from a first receiving width to a second receiving width. The essential difference between the first and second embodiments lies in the arrangement and design of the receiving units 31a, 31b: It can be seen from the Fig. 11a and Fig. 11b, it is evident that the receiving units 31a, 31b each have a first receiving claw 32a for receiving the first container B1 and a second receiving claw 32b for receiving the second container B2 with a smaller span d, which are preferably arranged on a common base body 33 and are preferably designed as integral components thereof. The two receiving units 31a, 31b are hook-shaped, the base body 33 having a bearing opening 34 for a bearing axis 19, via which the receiving units 31a, 31b can be attached to the tilting arms 11a, 11b.

[0028] As can now be seen from the aforementioned figures, in the second embodiment this bearing axis 19 is no longer arranged collinearly with the axis of rotation of the tilting device 10 defined by the receiving elements 15a, 15b of the containers B1, B2, as in the first embodiment, but rather it runs orthogonally to it. Fig. 9a and Fig. Figure 9b shows the tipping device 10 with the larger container B1 held in it. It can be seen that the first receiving claws 32a are in the first working position suitable for holding the container B1. In this first position of the receiving claws 20 of the tipping arms 11a, 11b, the tipping device 10 thus has a first receiving width suitable for holding the container B1 with a span D.

[0029] The Fig. 10a and Fig. Figure 10b shows the tipping device 10 with the second container B2 held in it. It can be seen that in this case, the second receiving claws 32b of the receiving units 31a, 31b are in the second working position. The transition between the first and second positions of the receiving 20 of the tipping device 10 occurs such that the receiving units 31a, 31b are pivoted about their bearing axes 19. Since the distance between the two receiving claws 32a and 32b of each receiving unit 31a, 31b is essentially half the difference between the larger first receiving width required for holding the first container B1 and the second receiving width required for holding the smaller second container B2, the second receiving claws 32b of the tipping arms 11a, 11b are positioned as a comparison between the Fig. 9a, Fig. 9b and Fig. 10a, Fig. 10b shows, in the axial direction of the tilting device 10 further inwards, the tilting device 10 thus has the second receiving width required or suitable for receiving the second container B2.

[0030] In the Fig. Figures 12a to 14 show a third embodiment of a tilting device 10. Corresponding components are again designated with the same reference numerals and are not described in further detail. Fig. 12a and Fig. Figure 12b shows the tipping device 10 with the first container B1, which Fig. 13a and Fig. 13b the tipping device 10 with the second container B2 and the Fig. Figure 14 shows a receiving unit 41a of the third embodiment in its working position, which serves to receive both the first container B1 and the second container B2. The essential difference between the first two embodiments and the third embodiment of the tipping device 10 shown in the aforementioned figures lies again in the function and design of the receiving units 41a, 41b, which are movably arranged on the two tipping arms 11a, 11b.

[0031] In the Fig. Figure 14 again shows the left-hand receiving unit 41a in the assembled state. The second receiving unit 41b, arranged on the second tilting arm 11b, is designed accordingly. It can be seen from the figures that in the third embodiment, the receiving units 41a and 41b each have only one receiving claw 42, which—as described below—serves to receive both the first container B1 with a span D and the second container B2 with a span d.

[0032] In contrast to the first two embodiments, in which the adjustment movement of the mountings 20 of the tilting arms 11a, 11b was effected by a rotational movement of the mounting units 21a, 21b and 31a, 31b, the third embodiment provides that the mounting units 41a, 41b are moved translationally to change the mounting width of the tilting device 10. The mounting units 41a, 41b are L-shaped and have an elongated base body 43. Each tilting arm 11a, 11b has a bearing opening 44 into which the base body 43 of the mounting units 41a, 41b can be slidably inserted. Preferably, the cross-section of the base body 43 is non-circular, preferably rectangular or polygonal, and the bearing openings 44 have a correspondingly adapted inner contour. This prevents the base body 43 from twisting in the bearing opening 44.

[0033] The Fig. 12a and Fig. Figure 12b again shows the tilting device 10 with the first container B1 contained therein and the Fig. 13a and Fig. 13b the tipping device 10 with the second container B2. In the Fig. 12a and Fig. In section 12b, the receiving units 41a, 41b of the receiving units 20 of the two tipping arms 11a, 11b are in their first working position, in which the tipping device 10 has the first receiving width required for receiving the larger container B1. It can be seen that the base bodies 43 of the receiving units 41a, 41b protrude from the bearing openings 44 of the tipping arms 11a, 11b.

[0034] To adjust the second clamping width of the tilting device 10, the clamping units 41a, 41b are translationally displaced in the longitudinal direction of their base bodies 43. This can be seen from the Fig. 13a and Fig. 13b, that in the second position of the recordings 20 the base body 43 of the recording units 41a, 41b protrudes less far from the bearing openings 44 of the tilting arms 11a and 11b.

[0035] In the Fig. Figures 15a to 17b now show a fourth embodiment of the tilting device 10, in which corresponding components are again provided with the same reference numerals and are not described in further detail. Fig. 15a and Fig. Figure 15b shows the tipping device 10 with the first container B1, which Fig. 16a and Fig. 16b the tipping device 10 with the second container B2 and the Fig. 17a and Fig. 17b a receiving unit 51a corresponding to the receiving units of the embodiments described above, which – as described below – is movably attached to the first tilting arm 11a. The second receiving unit 51b corresponds in its construction to that described in the Fig. 17a and Fig. 17b shown first receiving unit 51a. The difference between the fourth embodiment and the first three embodiments described above lies again in the design of the receiving units 51a, 51b of the receivings 20 of the tilting arms 11a, 11b and, consequently, in the resulting kinematics during the transition between the first and second working positions of the receiving units 51a, 51b for adjusting the first and second receiving width of the tilting device 10.

[0036] Here too, the receiving units 51a, 51b – as in the third embodiment – ​​again have only one receiving claw 52, ​​which serves to receive both the first container B1 and the second container B2. The receiving claw 52 is rotatably arranged on a parallelogram-shaped base body 53, which has a longitudinal member 53a and two transverse members 53b and 53c, each of which is pivotally connected at one end to the longitudinal member 53a.

[0037] How best to get from the Fig. As can be seen in Figures 15a to 16b, a crossbeam 53d is arranged in each tilting arm 11a, 11b, to which the cross members 53b, 53c of the base body 53 of the receiving units 51a, 51b are pivotally attached. This crossbeam 53d and the cross members 53b, 53c thus form a parallelogram-like guide for the receiving claw 52 of the receiving units 51a, 51b, which allows the receiving width of the tilting device 10 to be changed by a corresponding adjustment movement.

[0038] By pivoting the recording units 51a, 51b from their in Fig. 15a, Fig. 15b shown first working position in their in Fig. 16a, Fig. In the second working position shown in 16b, the tilting device 10 is moved from its first taking-up distance to its second working position, in which it has the smaller second taking-up distance.

[0039] The preceding description assumes that both tilting arms 11a, 11b each have a receiving unit 21a, 21b or 31a, 31b or 41a, 41b or 51a, 51b that is movable relative to the respective tilting arm 11a, 11b, so that a change in the receiving width of the tilting device 10 is achieved by moving both receiving units 21a, 21b or 31a, 31b or 41a, 41b or 51a, 51b. However, it is also entirely possible that such a receiving unit 21a, 21b or 31a, 31b or 41a, 41b or 51a, 51b is provided on only one tilting arm 11a or 11b. This can be the case, for example, if the tilting device 10 has a 21a, 21b or 31a, 31b or 41a, 41b or 51a, 51b. B. may be sufficient if the difference between the spans D and d of the containers B1 and B2 is only slight, so that the required change in the receiving spans can be achieved by moving only a single receiving element.Although such a design is possible, it is not preferred because it usually leads to a one-sided distribution of the load of the container B1, B2 to be absorbed by the tipping device 10.

[0040] The above-described configurations of the tipping device 10 allow the loading and unloading of a detachable container B1, B2. In order to also enable the tipping of such a container B1 or B2, which is held between the tipping arms 11a, 11b, the containers B1 and B2 have locking elements in a manner known per se, which interact with corresponding container locking devices of the tipping arms 11a, 11b.

[0041] The one in the Fig. 2a and Fig. The first container B1 shown in 2b has, in a manner known per se, a front pair and a rear pair of - here pocket-shaped - locking elements 61a, 61b and 61c, 61d, so that the container B1 can be inserted into the tilting device 10 in two different orientations in a manner known per se.

[0042] The one in the Fig. 3a and Fig. The first container B2 shown in 3b has a web 62a, 62b on each side as a locking element.

[0043] In the known tipping devices, which – as described – were designed to accommodate only one and the same container, the container locking devices on the tipping arms 11a, 11b, which served to lock the container held in the tipping device 10, were also matched to the locking receptacles of this container. Since the tipping device 10 described here is intended not only to pick up and set down differently configured containers B1 and B2, but preferably also to tip them, it is generally necessary for the corresponding tipping device 10 to also have two different locking devices for the locking receptacles of containers B1 and B2.

[0044] The locking devices 63 and 64 used in the described tilting device 10 are described with reference to the first embodiment, since the tilting arms 11a, 11b are constructed identically in the other embodiments, a description of the further embodiments is unnecessary.

[0045] The first locking device 63 serves to lock the first container B1 in the tipping device 10, and the second locking device 64 allows the second container B2 to be fixed in position within the tipping device 10 during a pivoting movement, such that when the tipping device 10 tilts, the container B1, B2 is carried along, thus enabling the container B1, B2 to be tipped out. Depending on the orientation of the container B1 in the tipping device 10, the first locking device 63 interacts either with the front pair of locking elements 61a, 61b or the rear pair of locking elements 61c, 61d. For this purpose, it may be provided that the first locking device 63 has two extendable pistons (not shown) each attached to a tilting arm 11a, 11b, which engage in the corresponding locking elements 61a, 61b or 61c, 61d.The second locking device 64 interacts with the locking elements 62a, 62b of the second container B2 in a corresponding manner.

[0046] In summary, it can be stated that the described measures advantageously design a tipping device 10 which allows the lifting width of the tipping device 10 to be easily changed, so that containers of different configurations, in particular different diameters, can be used in one and the same tipping device 10. Thus, with a transport vehicle 1 using such a tipping device 10, it is possible to transport containers B1, B2 with different spans D, d, in particular to pick them up, unload them and preferably tip them out.
