Description

TECHNICAL FIELD

[0001] The utility model relates to a slipform paver. BACKGROUND

[0002] Slipform pavers, such as known from DE 199 57 048, generally comprise a machine frame, a travel device 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 work device. The work device enables a ground paving or structure to be created. The work device can be, for example, a concrete form, and can be positionally variable and replaceable or extendable. Furthermore, the travel device is generally connected to the machine frame in such a way that the travel device can change its position relative to the machine frame.

[0003] The at least one belt conveyor device can be connected to the machine frame in such a way that the belt conveyor device is pivotable relative to the machine frame at least about a substantially horizontal axis and at least about 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 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. At least one first actuator can be arranged and designed in such a way that the belt conveyor device is pivotable at least about a substantially horizontal axis, and at least one second actuator can be arranged and designed in such a way that the belt conveyor device is pivotable at least about 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 work device, in particular to the concrete form, which is used to build the ground paving or structure.

[0005] With the known slipform pavers, there is often the problem that the position of the material receiving area and / or the position of the work device changes or the work device itself is replaced. Therefore, there is an increasing demand for simplifying the operation of the conveyor device. SUMMARY

[0006] It is therefore an object of the utility model to create a slipform paver which simplifies the operation of the entire slipform paver, in particular the operation of the conveyor device.

[0007] The utility model advantageously provides at least one adjustment device which is designed in such a way 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] Thus, the adjustment device can adjust the first end portion and the second end portion of the belt conveyor device. This does not mean that both the first end portion and the second end portion of the belt conveyor device are always adjusted. Depending on the application, the adjustment device can only adjust the first end portion or the second end portion or both end portions. In this process, the adjustment 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 belt conveyor device can very well adapt to the environment and the application. It can be necessary to adjust the position of the material receiving area, in particular if the material has to be applied in different positions due to different requirements. Likewise, the position of the work device can change or the replacement of the work device requires the repositioning of the conveyor device accordingly. This adaptability makes the belt conveyor device particularly flexible in its application.

[0011] The adjustment device can be designed such that the first end portion and the second end portion can be adjusted independently of one another in the longitudinal direction of the belt conveyor device.

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

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

[0014] Adjusting the belt conveyor base makes it possible to adjust the entire belt conveyor device in the longitudinal direction of the belt conveyor device relative to the machine frame.

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

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

[0017] On the other hand, both can also be adjusted simultaneously or sequentially.

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

[0019] The adjustment device can comprise at least one first adjustment actuator and at least one second adjustment actuator.

[0020] The first adjustment actuator can be arranged and designed such that the belt conveyor base and thus the belt conveyor device can be adjusted by the first adjustment actuator in the longitudinal direction of the belt conveyor device relative to the machine frame. The second adjustment actuator can be arranged and designed such that 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 can be adjusted by the second adjustment actuator.

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

[0022] Alternatively, it can also be provided that the belt conveyor base is not designed to be adjustable, but that the first adjustment actuator adjusts the first return roller relative to the belt conveyor base and the second adjustment actuator adjusts the second return roller relative to the belt conveyor base. 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 a further alternative, the adjustment device can also comprise only one adjustment actuator. In this case, the belt conveyor base can first be adjusted by the adjustment actuator. To this end, the possibility of adjusting the spacing between the first return roller and the second return roller can be locked and the belt conveyor base can be adjusted by the adjustment device only. Then, the belt conveyor base can be locked relative to the machine frame and one actuator of the adjustment device can then be used to adjust only the at least one return roller with the belt conveyor base locked. This will also make it possible to perform two adjustment operations with only one adjustment actuator, namely, on the one hand, the adjustment of the belt conveyor base 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] It is also possible to provide at least two first adjustment actuators and / or at least two second adjustment actuators.

[0025] It can be advantageous to provide at least two adjustment actuators, for example, if two adjustment actuators are arranged on the sides of the belt conveyor, the forces are distributed evenly and no jerking occurs during the adjustment of the belt conveyor device.

[0026] The second adjustment actuator can be arranged and designed such that the first return roller and / or the second return roller are adjustable relative to the belt conveyor base, such that the spacing between the first return roller on the first end of the belt conveyor arrangement and the second return roller on the second end of the belt conveyor arrangement is adjustable.

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

[0028] The at least one return roller can 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 can be provided, around which the belt conveyor runs, wherein at least the third return roller can be adjustable such that the belt conveyor always exhibits a predetermined tension even when the spacing between the first return roller and the second return roller is adjusted. The predetermined tension is preferably the tension at which the function of the belt conveyor is guaranteed. Furthermore, instead of the at least one first return roller and / or the at least one second return roller, the at least one third and / or fourth return roller can additionally or alternatively be driven.

[0029] In this design, the third return roller can be adjusted with 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 by which the spacing between the first return roller and the second return roller changes. The third return roller is always adjusted such that the tension of the belt conveyor preferably remains essentially the same.

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

[0031] The maximum transport length of the belt conveyor arrangement can thus be between 130% and 200%, preferably between 140% and 160%, relative to the minimum transport length of the belt conveyor arrangement.

[0032] The at least one belt conveyor arrangement can be adjustable in height relative to the machine frame along an essentially vertical axis.

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

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

[0035] The belt conveyor can comprise an upper run and a lower run. The upper run can also be referred to as the load run. 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 run 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 run, also referred to as the empty run, is the lower part of the belt conveyor which returns to the loading point after the material has been unloaded. This lower part carries no load other than the self-weight of the belt and any residue of the transported material which has not been unloaded, at least one third return roller and at least one fourth return roller are preferably arranged on the lower run.

[0037] According to the invention, a method for constructing a ground-paved road or structure by means of a slipform paver comprising at least one machine frame, at least one belt conveyor device connected to the at least one machine frame, wherein the belt conveyor device is pivotable at least about a substantially horizontal axis and at least about a substantially vertical axis with respect to the machine frame, wherein the belt conveyor device comprises at least one first end and at least one second end. 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 is rotatable at least about one first return roller on the first end of the belt conveyor device and at least about one second return roller on the second end of the belt conveyor device, wherein at least one first actuator is pivotable the belt conveyor device at least about the horizontal axis, wherein at least one second actuator is pivotable the belt conveyor device at least about the vertical axis. Advantageously, it is provided that the first end and the second end of the belt conveyor device are adjustable in the longitudinal direction of the belt conveyor by means of an adjustment 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 the adjustment device.

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

[0054] Figure 1 A slipform paver 1 is shown. Slipform pavers can be used for constructing ground surfaces or structures. Slipform paver 1 can move in the operating 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. Additionally, at least one belt conveyor device 6 is provided.

Furthermore, the machine frame 2 comprises a machine frame part 201, the length of which in longitudinal direction 230 and in transverse direction 320 is variable.

These work devices 12 can be positioned differently by the machine frame part 201 relative to the ground engaging units 4 and in particular relative to the belt conveyor device 6.

[0060] The belt conveyor device comprises at least one first end portion 200 and a second end portion 202. The belt conveyor device 6 further comprises 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 on the first end portion 200 of the belt conveyor device 6 and at least around a second return roller 212 on the second end portion 202 of the belt conveyor device 6. At least one adjustment device 214 is provided, which is designed such that the first end portion 200 and the second end portion 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 portion 200 and the second end portion 202 can be adjusted independently of one another in the longitudinal direction L of the belt conveyor device 6.

[0062] The adjustment 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. The adjustment of the spacing between the first return roller 210 and the second return roller 212 makes it possible to adjust the length of the transport length of the belt conveyor 14.

[0063] In the depicted embodiment, the adjustment device 214 can comprise a first adjustment actuator 216 and at least one second adjustment 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 are adjustable by means of the first adjustment actuator 216 in the longitudinal direction L of the belt conveyor device 6 relative to the machine frame 2. Figure 4 Embodiments according to Figure 3 are depicted, in which the belt conveyor base 204 and thus the belt conveyor device 6 have been adjusted by means of the first adjustment actuator 216 in the longitudinal direction L of the belt conveyor device 6 relative to the machine frame 2.

[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 portion 200 and the second return roller 212 on the second end portion 202 is adjustable by means of the second adjustment actuator 218. Figure 5 Embodiments according to Figure 4 are depicted, in which the spacing between the first return roller 210 on the first end portion 200 and the second return roller 212 on the second end portion 202 has been adjusted by means of the second adjustment actuator 218.

[0066] Two different adjustment operations can be performed by the adjustment device 214. On the one hand, the belt conveyor base 204 can be adjusted in the longitudinal direction L of the belt conveyor device 6 relative to the machine frame 2. 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 one another.

[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 comprise only one adjustment actuator. In this case, the belt conveyor base 204 can first be adjusted by the adjustment actuator, which can be, for example, the adjustment actuator 216. For this purpose, the possibility of adjusting the spacing between the first return roller 210 and the second return roller 212 can be locked, and only the conveyor base 204 can be adjusted by the adjustment device 214. On the other hand, the belt conveyor base 204 can be locked relative to the machine frame 2, and one actuator of the adjustment device can then be used only for adjusting at least one return roller with the belt conveyor base 204 being locked.

[0070] This would 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 can comprise 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. The adjustment device can thus 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 in such a way that it rotates around the return rollers 210, 212.

[0073] Figure 6a ,Figure 6b , Figure 7 and Figure 8 Adjustment of the belt conveyor device 6 is shown. In this arrangement only the belt conveyor device 6 is shown schematically. Furthermore, only the first side 200 of the belt conveyor device 6 is shown. Furthermore, only a part of the belt conveyor 14 and the return rollers is depicted. Everything else is omitted for the sake of simplicity. On the first side 200, the belt conveyor 14 rotates around a first return roller 210. The return rollers can be adjusted by means of an adjustment actuator 218 as depicted in Figures 3 to 5 . This enables the adjustment of the distance between the first return roller 210 and the second return roller 212 (not shown in Figures 6a to 8 ). This changes the transport length of the belt conveyor which extends between the first return roller 210 and the second return roller 212.

[0074] Furthermore, as shown in Figure 6a , Figure 6b , Figure 7 and 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 means of the adjustment actuator 218 as depicted in Figures 3 to 5 , the third return roller 220 can also be moved, i.e. in such a way that the belt conveyor 14 always assumes the same amount of 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. It can thus be ensured that the belt conveyor 14 always rotates around the return rollers with essentially the same tension.

[0075] Figure 6b An embodiment according to Figure 6a is depicted, which 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 essentially corresponds to the distance between the first return roller 210 and the second return roller 212, is reduced in Figure 6b . The third return roller 220 is adjusted in such a way that the tension of the belt conveyor 14 remains essentially the same. The length of the path around which the belt conveyor 14 needs to rotate remains essentially constant at all times. The essentially constant length of the path around which the belt conveyor needs to rotate preferably results in an essentially constant tension of the belt conveyor 6. For the purposes of this application, an essentially constant tension means that the tension is maintained at least to such an extent that the functionality of the belt conveyor 6 is not impaired. This means that the belt is still able to convey material in any adjustment position and in particular the drive rollers do not slip relative to the belt conveyor.

[0076] An additional adjusting actuator can be provided for adjusting the third return roller 220, or the first adjusting actuator can 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 base of the belt conveyor. 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 interchanged, as long as it is ensured that the third return roller 220 moves in a manner that keeps the tension of the belt conveyor 14 substantially constant. In an alternative embodiment, the third return roller and the fourth return roller can also move, wherein the two return rollers then move in a manner that keeps the tension of the belt conveyor 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 is shown in Figure 6. However, the principle is the same as that in Figure 6. The return roller 220 is the third return roller, which moves when the first return roller 210 moves. Figure 7 The embodiments described herein require only a slightly smaller space.

[0078] according to Figure 8 The embodiments are consistent with Figure 6 and Figure 7 The embodiment shown operates on a similar principle. However, the third return roller 220 is arranged differently. The rotary belt conveyor 14 is first guided around the support roller 226, and then rotates around the third return roller 220, and then 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 may be configured with a corresponding [feature / equipment] according to [the specific requirements]. Figure 6a , Figure 6b , Figure 7 , Figure 8 The kinematic characteristics of the embodiments.

[0080] Furthermore, 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 increasing or decreasing the distance between the first return roller 210 and the second return roller 212. 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 the same amount in the same direction. In this case, it is not necessary 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 to move the belt conveyor 14 according to Fig. 6, Figure 7 and Figure 8 The return rollers 210 and 212 are provided with their own kinematics.

[0082] Figure 9 A view of the suspension of the belt conveyor device 6 is shown from below. However, for the sake of 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, it is also possible to see the first adjustment actuator 216 of the adjustment device 214.

[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 inferred from Figure 4 In the depicted embodiment, the second actuator 34 is connected on a first side to the parallelogram guide 106. On a second side, the second actuator 34 is connected in a pivotable manner to the connecting rod 108, which in turn is connected to the hollow column 110, which 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 be pivoted about the pivot axis 36 and thus about a vertical axis.

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

[0085] If the machine does not comprise 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 invention, horizontal does not necessarily mean that it is horizontal relative to the ground surface, but rather that it is horizontal relative to a plane defined by the longitudinal axis and the transverse axis of the machine frame. Vertical means that it is vertical relative to a plane defined by the longitudinal axis and the transverse axis of the machine frame.

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

[0088] Figure 11 A perspective view of the belt conveyor device 6 without 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 properties correspond to the design of the embodiment shown in Figure 8 .

[0090] As Figure 11 depicted, the belt conveyor can comprise an upper run 500 and a lower run 520. The upper run 500 can also be referred to as a load run. 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 carries the load of the material. As Figure 12 depicted in Figure 12 , the upper run 500 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 14 can also be supported by support rollers instead of support surfaces. Figure 11 depicted, however, without the belt conveyor 14.

[0091] The lower run 520, also referred to as an empty run, is the lower part of the belt conveyor 14, which returns to the loading point after the material has been unloaded. It carries no load other than the belt self-weight and the remaining part of any transported 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 run 520.
