Description

Field of the Invention

[0001] The invention relates to a slipform paver according to claim 1 and to a method for constructing a ground-paved road surface or structure by means of a slipform paver according to claim 13. Background Art

[0002] Slipform pavers known, for example, from DE 199 57 048 generally comprise a machine frame, travel devices connected to the machine frame, and at least one belt conveyor device. The belt conveyor device enables a material, such as concrete, to be transported to a working device. The working device enables a ground-paved road surface or structure to be created. The working device can be, for example, a concrete mold and can be positionally changeable and replaceable or extendable. In addition, the travel devices are generally connected to the machine frame in such a way that the travel devices can change their position relative to the machine frame.

[0003] The at least one belt conveyor device can be connected to the machine frame such that the belt conveyor device can pivot relative to the machine frame about at least a substantially horizontal axis and about at least a substantially vertical axis. The belt conveyor device can comprise at least one first end and at least one second end, wherein the belt conveyor device comprises at least one belt conveyor base and at least one belt conveyor arranged on the belt conveyor base, wherein the belt conveyor rotates about at least one first return roller at the first end of the belt conveyor device and rotates about a second return roller at least at the second end of the belt conveyor device. At least one first actuator can be arranged and designed such that the belt conveyor device pivots about at least a substantially horizontal axis, and at least one second actuator can be arranged and designed such that the belt conveyor device pivots about at least a substantially vertical axis.

[0004] The belt conveyor device can comprise a material receiving area for receiving concrete. The concrete is then transported via the belt conveyor device to the working device, in particular to the concrete mold, which is used for constructing a ground-paved road surface or structure.

[0005] For known slipform pavers, there are often problems with changing the position of the material receiving area and / or the position of the working device or with replacing the working device itself. Therefore, there is an increasing demand for simplifying the operation of the conveying device. Summary of the Invention

[0006] Therefore, an object of the present invention is to create a slipform paver and a method for constructing a ground-paved road surface or structure by means of a slipform paver, which simplify the operation of the entire slipform paver, in particular the operation of the conveying device.

[0007] The invention advantageously provides for at least one adjusting device which is designed such that the first end and the second end of the belt conveyor device can be adjusted in the longitudinal direction of the belt conveyor device.

[0008] Accordingly, the adjusting device can adjust the first end and the second end of the belt conveyor device. This does not mean that both the first end and the second end of the conveyor belt device are always adjusted. Depending on the application, the adjusting device can adjust only the first end or the second end or both ends. In this process, the adjusting operations can be carried out simultaneously or also sequentially.

[0009] The longitudinal direction of the belt conveyor device corresponds to the longitudinal direction of the belt conveyor. The longitudinal direction of the belt conveyor device or the longitudinal direction of the belt conveyor preferably extends parallel to the transport direction of the belt conveyor device.

[0010] Thus, the advantage of the present invention is that the belt conveyor device can be very well adapted to the environment and the application. It may be necessary to adjust the position of the material receiving area, especially if the material has to be applied at different positions due to different requirements. Similarly, the position of the working device may change or the replacement of the working device requires a corresponding repositioning of the conveying device. This adaptability makes the belt conveyor device particularly flexible in its application.

[0011] The adjusting device can be designed such that the first end and the second end can be adjusted independently of each other in the longitudinal direction of the belt conveyor device.

[0012] The first end and the second end can be adjusted, for example, in different directions or also in the same direction by different amounts.

[0013] The adjusting device can be designed such that the belt conveyor base and thus the belt conveyor device are adjustable in the longitudinal direction of the belt conveyor device relative to the machine frame, and the spacing between the first return roller on the first end of the belt conveyor device and the second return roller on the second end of the belt conveyor device is adjustable.

[0014] Adjusting the belt conveyor base enables the entire belt conveyor device to be adjusted relative to the machine frame in the longitudinal direction of the belt conveyor device.

[0015] Adjusting the spacing between the first return roller on the first end of the belt conveyor device and the second return roller on the second end of the belt conveyor device allows the transport length of the belt conveyor to be adjusted.

[0016] The adjusting device can be designed to be able to adjust both the base of the belt conveyor and the conveying length of the belt conveyor. This does not mean that both must always be adjusted. Under certain conditions, it is possible to adjust only the base of the belt conveyor or the length of the belt conveyor.

[0017] On the other hand, it is also possible to adjust both simultaneously or in sequence.

[0018] The adjusting device can be designed such that the first and / or second return rollers can be adjusted relative to the base of the belt conveyor, so that the spacing between the first return roller at the first end of the belt conveyor device and / or the second return roller at the second end of the belt conveyor device is adjustable.

[0019] The adjusting device can include at least one first adjusting actuator and at least one second adjusting actuator.

[0020] The first adjusting actuator can be arranged and designed such that the base of the belt conveyor and thus the belt conveyor device can be adjusted relative to the machine frame in the longitudinal direction of the belt conveyor device by the first adjusting actuator. The second adjusting actuator can be arranged and designed such that the spacing between the first return roller at the first end of the belt conveyor device and the second return roller at the second end of the belt conveyor device can be adjusted by the second adjusting actuator.

[0021] The base of the belt conveyor can be adjusted by the first adjusting actuator. The length of the belt conveyor can be adjusted by the second adjusting actuator.

[0022] Alternatively, it can also be provided that the base of the belt conveyor is not designed to be adjustable, but the first adjusting actuator adjusts the first return roller relative to the base of the belt conveyor, and the second adjusting actuator adjusts the second return roller relative to the base of the belt conveyor. This allows the spacing between the first return roller and the second return roller to be adjusted, or the first return roller and the second return roller can be adjusted in the same direction by the same amount.

[0023] In another alternative, the adjusting device can also include only one adjusting actuator. In this case, the base of the belt conveyor can first be adjusted by the adjusting actuator. For this purpose, the possibility of adjusting the spacing between the first return roller and the second return roller can be locked, and only the base of the belt conveyor can be adjusted by the adjusting device. Then, the base of the belt conveyor can be locked relative to the machine frame, and in the case where the base of the belt conveyor is locked, one actuator of the adjusting device can then be used to adjust only at least one return roller. This will also make it possible to perform two adjusting operations with only one adjusting actuator, namely, on the one hand, the adjustment of the base of the belt conveyor relative to the machine frame, and on the other hand, the adjustment of the spacing between the first return roller and the second return roller.

[0024] At least two first adjusting actuators and / or at least two second adjusting actuators may also be provided.

[0025] It may be advantageous to provide at least two adjusting actuators. For example, if two adjusting actuators are provided on the sides of the belt conveyor, the forces are evenly distributed and jamming does not occur during the adjustment of the belt conveyor device.

[0026] The second adjusting actuator may be arranged and designed such that the first return roller and / or the second return roller is adjustable relative to the belt conveyor base, such that the spacing between the first return roller at the first end of the belt conveyor device and the second return roller at the second end of the belt conveyor device is adjustable.

[0027] Therefore, the second adjusting actuator may be arranged and designed such that the first return roller and / or the second return roller is adjustable relative to the belt conveyor base, such that the length of the belt conveyor is adjustable.

[0028] At least one return roller may be driven such that the return roller can drive the rotating belt conveyor. In addition to the first return roller and the second return roller, at least one third return roller and at least one fourth return roller may also be provided, around which the belt conveyor runs, wherein at least the third return roller may be adjustable such that even when adjusting the spacing between the first return roller and the second return roller, the belt conveyor always exhibits a predetermined tension. The predetermined tension is preferably the tension under which the function of the belt conveyor is ensured. In addition, instead of at least one first return roller and / or at least one second return roller, at least one third and / or fourth return roller may additionally or alternatively be driven.

[0029] In this design, the third return roller may be adjusted at the same spacing as the first return roller or the second return roller. If the first return roller and the second return roller are adjusted simultaneously, the third return roller is preferably adjusted by the amount of change in the spacing between the first return roller and the second return roller. The third return roller is always adjusted such that the tension of the belt conveyor preferably remains substantially the same.

[0030] Relative to the minimum spacing between the first return roller and the second return roller, the maximum spacing between the first return roller and the second return roller may be 130% to 200%, preferably 140% to 160%.

[0031] Therefore, relative to the minimum transport length of the belt conveyor device, the maximum transport length of the belt conveyor device may be between 130% and 200%, preferably between 140% and 160%.

[0032] The at least one belt conveyor device can be adjustable in height relative to the machine frame along a substantially vertical axis.

[0033] This has the advantage that the belt conveyor device can be adjusted even more flexibly.

[0034] The at least one belt conveyor device can preferably be movable relative to the machine frame in a horizontal plane by means of a parallelogram guide.

[0035] The belt conveyor can include an upper running part and a lower running part. The upper running part can also be referred to as the load running part. This is the upper part of the belt conveyor on which the material to be transported is located. This upper part moves from the loading point to the unloading point and carries the load of the material. The upper running part is preferably supported by a series of support surfaces or bearing surfaces which ensure that the belt does not sag under the load of the material. Alternatively, the belt conveyor can also be supported by support rollers instead of support surfaces.

[0036] The lower running part, also known as the empty running part, is the lower part of the belt conveyor which returns to the loading point after the material has been unloaded. This lower part does not carry any load other than the self-weight of the belt and any residue of the transported material that has not been unloaded, and at least one third return roller and at least one fourth return roller are preferably arranged on the lower running part.

[0037] According to the invention, a method for constructing a ground paving surface or structure by means of a slipform paver can be provided, the slipform paver including at least one machine frame to which at least one belt conveyor device is connected, wherein the belt conveyor device is capable of pivoting relative to the machine frame at least about a substantially horizontal axis and at least about a substantially vertical axis, wherein the belt conveyor device includes at least one first end and at least one second end. The belt conveyor device includes at least one belt conveyor base and at least one belt conveyor arranged on the belt conveyor base, wherein the belt conveyor can rotate at least about a first return roller on the first end of the belt conveyor device and at least about a second return roller on the second end of the belt conveyor device, wherein at least one first actuator can pivot the belt conveyor device at least about a horizontal axis, and wherein at least one second actuator can pivot the belt conveyor device at least about a vertical axis. It is advantageously provided that the first end and the second end of the belt conveyor device can be adjusted in the longitudinal direction of the belt conveyor by means of an adjusting device.

[0038] The first end and the second end can be adjusted independently of each other in the longitudinal direction of the belt conveyor device by means of an adjusting device.

[0039] The first end portion and the second end portion can be adjusted simultaneously or sequentially. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] Figure 1 A slipform paver 1 is shown. The slipform paver can be used for constructing a ground paving road surface or structure. The slipform paver 1 can move in the operation direction A.

[0055] The slipform paver 1 includes at least one machine frame 2. A traveling device 4 is connected to the machine frame 2. Furthermore, at least one belt conveyor device 6 is provided. The belt conveyor device 6 can be used, for example, to convey concrete to the working device 12( Figure 2 ). The working device can be used to construct a ground paving surface or structure. The working device can be, for example, a concrete mold. The working device can be replaceable and can also be position-variable, or it can additionally or alternatively be extensible. The traveling devices 4 can be connected to the machine frame in such a way that the traveling devices 4 can change their position relative to the machine frame.

[0056] The slipform paver 1 is depicted in FIG. 1, where the length of the longitudinal member 81 of the machine frame 2 is variable. Furthermore, the machine frame 2 also includes a machine frame part 201, the length of which is variable in the longitudinal direction 230 and the transverse direction 320. Different working devices 12 (such as concrete molds of different shapes) can be attached to the machine frame part 201. These working devices 12 can be positioned differently relative to the ground engaging unit 4 and in particular relative to the belt conveyor device 6 by means of the machine frame part 201.

[0057] Material can be picked up by the belt conveyor device 6 and conveyed into the working device 12 for constructing a paving surface or structure.

[0058] In Figure 2 , the belt conveyor device 6 is depicted in more detail, where the material is picked up at the material receiving part 8 and placed at point 10 into the working device 12 designed as a concrete mold.

[0059] In Figure 3 the belt conveyor device 6 is depicted in more detail. The belt conveyor device 6 includes a belt conveyor 14, which is in Figure 3is shown in. The belt conveyor 14 and thus the belt conveyor device 6 can be pivoted about a substantially horizontal pivot axis 19 by means of at least one first actuator 22. Furthermore, the conveyor device 6 can be pivoted about a substantially vertical pivot axis 36 by means of a second actuator 34. The pivot axis 19 is preferably arranged below the belt conveyor 14. As depicted in the embodiment, the pivot axis 19 can be arranged in the upper third of the conveying device 6. In another preferred embodiment, the pivot axis 19 can be arranged in the region of the middle third of the conveying device 6. In the depicted embodiment, the depicted first actuator 22 is mounted on a connecting element 100 so as to pivot about a pivot axis 102. The connecting element 100 is arranged on a parallelogram guide 106. The first actuator 22 is also mounted at a second end and also pivots about a pivot axis 103. The belt conveyor device 6 can also be translated manually or by means of an additional actuator in height along a substantially vertical axis 36.

[0060] The belt conveyor device includes at least one first end 200 and a second end 202. The belt conveyor device 6 also includes at least one belt conveyor base 204 and at least one belt conveyor 14 arranged on the belt conveyor base 204. The belt conveyor 14 runs around at least one first return roller 210 at the first end 200 of the belt conveyor device 6 and at least around a second return roller 212 at the second end 202 of the belt conveyor device 6. At least one adjusting device 214 is provided, which is designed such that the first end 200 and the second end 202 of the belt conveyor device 6 are adjustable in the longitudinal direction L of the belt conveyor device 6. The longitudinal direction of the belt conveyor device 6 is also the longitudinal direction L of the belt conveyor 14.

[0061] The first end 200 and the second end 202 can be adjusted independently of each other in the longitudinal direction L of the belt conveyor device 6.

[0062] The adjusting device 214 can be designed such that, on the one hand, the belt conveyor base 204 and thus the belt conveyor device 6 are adjustable in the longitudinal direction L of the belt conveyor device 6 relative to the machine frame 2, and on the other hand, the spacing B between the first return roller 210 and the second return roller 212 is adjustable. Adjusting the spacing between the first return roller 210 and the second return roller 212 enables the length of the conveying length of the belt conveyor 14 to be adjusted.

[0063] In the depicted embodiment, the adjusting device 214 can include a first adjusting actuator 216 and at least one second adjusting actuator 218.

[0064] The first adjustment actuator 216 can be arranged and designed such that the belt conveyor base 204 and thus the belt conveyor device 6 can be adjusted relative to the machine frame 2 in the longitudinal direction L of the belt conveyor device 6 by the first adjustment actuator 216. Figure 4 illustrates an embodiment according to Figure 3 which the belt conveyor base 204 and thus the belt conveyor device 6 have been adjusted relative to the machine frame 2 in the longitudinal direction L of the belt conveyor device 6 by the first adjustment actuator 216.

[0065] The second adjustment actuator 218 can be arranged and designed such that the spacing between the first return roller 210 on the first end 200 and the second return roller 212 on the second end 202 can be adjusted by the second adjustment actuator 218. Figure 5 illustrates an embodiment according to Figure 4 which the spacing between the first return roller 210 on the first end 200 and the second return roller 212 on the second end 202 has been adjusted by the second adjustment actuator 218.

[0066] Two different adjustment operations can be carried out by the adjustment device 214. On the one hand, the belt conveyor base 204 can be adjusted relative to the machine frame 2 in the longitudinal direction L of the belt conveyor device 6. On the other hand, the spacing between the first return roller 210 and the second return roller 212 can be adjusted. The transport length of the belt conveyor 6 can be adjusted by the spacing between the first return roller 210 and the second return roller 212.

[0067] Thus, on the one hand, the belt conveyor base 204 can be adjusted relative to the machine frame 2 by the adjustment device 214, and on the other hand, the transport length of the belt conveyor 6 can be adjusted by the adjustment device 214.

[0068] As a result, the first end 200 of the belt conveyor device 6 and the second end 202 of the belt conveyor device 6 can be adjusted. The first end 200 and the second end 202 can be adjusted independently of each other.

[0069] The first return roller 210 and / or the second return roller 212 can be adjusted relative to the belt conveyor base 204. In an embodiment not shown, the adjustment device 214 can also include only one adjustment actuator. In this case, the belt conveyor base 204 can first be adjusted using the adjustment actuator, which can be, for example, the adjustment actuator 216. To this end, the possibility of adjusting the spacing between the first return roller 210 and the second return roller 212 can be locked, and the conveyor base 204 can only be adjusted using the adjustment device 214. Alternatively, the belt conveyor base 204 can be locked relative to the machine frame 2, and when the belt conveyor base 204 is locked, the one actuator of the adjustment device can then be used only to adjust at least one return roller.

[0070] This will make it possible to perform two adjustment operations with a single adjustment actuator, namely, on the one hand, the adjustment of the belt conveyor base 204 relative to the machine frame 2 and, on the other hand, the adjustment of the spacing between the first return roller 210 and the second return roller 212 .

[0071] In another embodiment not shown, the adjustment device 214 may include two adjustment actuators, each of which can adjust the first end and the second end relative to the belt conveyor base, wherein the belt conveyor base is not adjusted relative to the machine frame in the longitudinal direction of the belt conveyor device. Thus, the adjustment device can also adjust the first end and the second end.

[0072] At least one return roller can be driven. This can be, for example, the return roller 212. The return roller 212 can then drive the belt conveyor 6 so that it rotates around the return rollers 210, 212.

[0073] Figure 6a , Figure 6b , Figure 7 and Figure 8 The adjustment of the belt conveyor device 6 is shown. In this arrangement, the belt conveyor device 6 is only shown schematically. In addition, only the first side 200 of the belt conveyor device 6 is shown. In addition, only a part of the belt conveyor 14 and the return roller is depicted. For the sake of simplicity, everything else is omitted. On the first side 200, the belt conveyor 14 rotates around the first return roller 210. The return roller can be Figures 3 to 5 This enables adjustment of the first return roller 210 and the second return roller 212 ( Figures 6a to 8 This changes the transport length of the belt conveyor extending between the first return roller 210 and the second return roller 212.

[0074] In addition, if Figure 6a , Figure 6b ,Figure 7 and Figure 8 As shown in Figure 8 , a third return roller 220 and a fourth return roller 222 can be provided. If the first return roller 210 is moved by the adjustment actuator 218 depicted in Figures 3 to 5 , the third return roller 220 can also be moved, i.e., moved by an amount such that the belt conveyor 14 always exhibits the same tension. If the first return roller 210 is moved relative to the second return roller 212, i.e., by an amount X, the third return roller 220 can be moved in the same direction by the same amount X. Thus, it can be ensured that the belt conveyor 14 always rotates around the return rollers with substantially the same tension.

[0075] Figure 6b Depicting an embodiment according to Figure 6a only has an adjusted first return roller 210 and thus also an adjusted third return roller 220. The transport length of the belt conveyor 14 (which substantially corresponds to the spacing between the first return roller 210 and the second return roller 212) is reduced in Figure 6b . The third return roller 220 is adjusted such that the tension of the belt conveyor 14 remains substantially the same. The length of the path around which the belt conveyor 14 needs to rotate always remains substantially constant. The substantially constant length of the path around which the belt conveyor needs to rotate preferably results in a substantially constant tension of the belt conveyor 6. For the purposes of the present application, a substantially constant tension means that the tension is maintained at least to the extent that the function of the belt conveyor 6 is not impaired. This means that the belt is still able to convey material in any adjusted position, and in particular, the drive roller does not slip relative to the belt conveyor.

[0076] Additional adjustment actuators can be provided for adjusting the third return roller 220, or the first adjustment actuator can also be used, for example, by mechanically coupling the third return roller to the first return roller 210. The fourth return roller 222 is not adjusted relative to the belt conveyor base. The positions of the third return roller 220 and the fourth return roller 222 can of course vary. The positions of the third return roller and the fourth return roller can even be exchanged, as long as it is ensured that the third return roller 220 moves in such a way that the tension of the belt conveyor 14 remains substantially constant. In an alternative embodiment, the third return roller and the fourth return roller can also be moved, where the two return rollers then move in such a way that the tension of the belt conveyor remains substantially the same. In such an embodiment, when the first return roller 210 is adjusted by an amount X, the third return roller 220 can, for example, move in the same direction as the first return roller 210 by an amount X / 2, and the fourth return roller 222 moves in the opposite direction to the first return roller 210 and the third return roller 220 by an amount X / 2.

[0077] Figure 7 ​​​​Another embodiment of FIG. 6 is shown. However, the principle is the same as that in FIG. 6. The return roller 220 is the third return roller, and when the first return roller 210 moves, the third return roller also moves. Figure 7 The embodiment depicted in Figure 7 requires only slightly less space.

[0078] According to Figure 8 the embodiment of Figure 8 works on a principle similar to the embodiments shown in FIG. 6 and Figure 7 However, the third return roller 220 is arranged differently. The rotary belt conveyor 14 is first guided around the support roller 226, then rotated around the third return roller 220, and then rotated around the fourth return roller 222. Also in this embodiment, the third return roller 220 can move by the same amount as the first return roller 210.

[0079] Alternatively, instead of the first return roller 210, the second return roller 212 can be provided with kinematic characteristics corresponding to those according to Figure 6a , Figure 6b , Figure 7 , Figure 8 the embodiment of Figure 8 .

[0080] In addition, the first return roller 210 and the second return roller 212 can also move relative to the belt conveyor base 204. In this case, the third return roller 220 must move by the amount by which the spacing between the first return roller 210 and the second return roller 212 increases or decreases. If the first return roller 210 and the second return roller 212 move relative to the belt conveyor base 204, it is also possible that the first return roller 210 and the second return roller 212 are adjusted by an amount in the same direction. In this case, there will be no need to adjust the third return roller 220.

[0081] In principle, it is also possible to move the first return roller 210 and the second return roller 212 relative to the belt conveyor base 204, and according to FIG. 6, Figure 7 and Figure 8 provide their own kinematic characteristics for both return rollers 210 and 212.

[0082] Figure 9 A view of the suspension of the belt conveyor device 6 as seen from below is shown. However, for clarity, the belt conveyor device 6 itself is not shown. This view depicts at least one first actuator 22 and at least one second actuator 34. In addition, the first adjustment actuator 216 of the adjustment device 214 can also be seen.

[0083] The second actuator 34 can pivot the belt conveyor device 6 about a vertical pivot axis 36. The pivot axis 36 preferably intersects the belt conveyor 14. In addition, the pivot axis 36 can extend through the pivot axis 19. This can also be seen from Figure 4It is inferred that. In the depicted embodiment, the second actuator 34 is connected to the parallelogram guide 106 on the first side. On the second side, the second actuator 34 is pivotally connected to the link 108, which in turn is connected to the hollow column 110, and the hollow column 110 is connected to the belt conveyor device 6. By operating and extending or retracting the second actuator 34 respectively, the hollow column 110 and thus the conveyor device 6 can pivot about the pivot axis 36 and thus about the vertical axis.

[0084] In addition, Figure 9 An optional additional actuator 24 is also depicted therein. It can be used to adjust the entire belt conveyor device 6 using the parallelogram guide 106. The parallelogram guide 106 is arranged on the machine frame 2.

[0085] If the machine does not include the optional additional actuator 24 and the parallelogram guide 106, the axis 36 can also be arranged on the machine frame.

[0086] In the sense of the present invention, horizontal does not necessarily mean horizontal with respect to the ground surface, but horizontal with respect to the plane defined by the longitudinal axis and the transverse axis of the machine frame. Vertical means vertical with respect to the plane defined by the longitudinal axis and the transverse axis of the machine frame.

[0087] Figure 10 A top view showing the suspension of the belt conveyor device 6 is shown. However, for clarity, the belt conveyor device 6 is not depicted. The top view depicts the optional additional actuator 24. The additional actuator 24 can pivot the entire belt conveyor device 6 in parallel. In this embodiment, the optional additional actuator 24 pivots the belt conveyor device 6 through the parallelogram guide 106. In Figure 10 two links 26 and 28 are depicted, each link pivoting about the rotation axes 30 and 32 respectively.

[0088] Figure 11 A perspective view of the belt conveyor device 6 without the suspension is shown. Figure 11 The belt conveyor 14, the belt conveyor base 204, the first end 200 and the second end 202, and the first return roller 210, the second return roller 212, the third return roller 220, and the fourth return roller 222 are depicted.

[0089] The kinematic characteristics correspond to the design of the embodiment shown in Figure 8 the embodiment shown.

[0090] As Figure 11As depicted, the belt conveyor may include an upper running section 500 and a lower running section 520. The upper running section 500 may also be referred to as the load running section. This is the upper part of the belt conveyor 14, on which the material to be transported is located. This upper part moves from the loading point to the unloading point and bears the load of the material. As Figure 12 depicted therein, the upper running section 500 is preferably supported by a series of support surfaces or bearing surfaces, which ensures that the belt does not sag under the load of the material. Alternatively, the belt conveyor 14 may also be supported by support rollers instead of support surfaces. Figure 12 depicts an embodiment according to Figure 11 but without the belt conveyor 14.

[0091] The lower running section 520, also known as the empty running section, is the lower part of the belt conveyor 14, which returns to the loading point after the material is unloaded. It does not bear any load except for the self-weight of the belt and the remaining part of any untransported material that has not been unloaded. At least one third return roller and at least one fourth return roller are preferably arranged on the lower running section 520.
