Abstract
Description
Technical Field
[0001] This utility model relates to slipform pavers and to a method for constructing pavement or structures using slipform pavers. Background Technology
[0002] Slipform pavers, particularly those known from DE 199 57 048, include at least one machine frame, a traveling device connected to the machine frame, and at least one conveying device. The conveying device can be used, for example, to transport concrete to a working device. The working device can be used to construct a pavement or structure. The working device can be, for example, a concrete mold. The working device can be replaceable and can also be repositionable or extendable. The traveling device can be connected to the machine frame in such a way that its position can be changed relative to the machine frame.
[0003] The conveying device can be connected to the machine frame in such a way that it can pivot relative to the machine frame at least about a horizontal axis and at least about a vertical axis, and preferably can translate in at least one first direction. An actuator can move the conveying device about the respective axis and, if desired, in the respective direction. The conveying device can be moved within a movement area defined relative to the machine frame by means of the actuator.
[0004] The conveying device includes a material picking area for picking up concrete. The concrete is then transported via the conveying device to the working device, particularly to the concrete mold, which is used to construct ground paving or structures.
[0005] For known slipform pavers, there is often a problem where the operator must control both the slipform paver itself and the conveyor system, which is part of the slipform paver and used to transport material placed in the concrete mold. Therefore, there is a growing demand for simplifying the operation of the conveyor system.
[0006] When supplying concrete to a slipform paver, the supply vehicle needs to load the concrete onto the conveyor at a first end. The conveyor may include, for example, a pickup device at the first end. For instance, when changing supply vehicles, it may be necessary to adjust the position of the first end of the conveyor to ensure continuous loading, while the position of the second end of the conveyor should not be changed at all or should be changed as little as possible, at which point the material is conveyed into the concrete mold.
[0007] On the other hand, it may be necessary to keep the first end of the conveyor (where the loading of the conveyor occurs) in a constant position when loading concrete onto the slipform paver, and to adjust the position of the material being conveyed into the concrete mold in order to optimize the filling of the concrete mold. Summary of the Invention
[0008] Therefore, the purpose of this invention is to provide a slipform paver and a method for constructing ground paving or structures using the slipform paver, which simplifies the operation of the entire slipform paver, especially the operation of the conveying device.
[0009] The above objectives are achieved by means of the features of this utility model.
[0010] The slipform paver according to the present invention comprises: at least one machine frame; at least three traveling devices connected to the machine frame; at least one conveying device connected to the machine frame such that the conveying device is pivotable relative to the machine frame at least about a horizontal axis and at least about a vertical axis; at least one first actuator arranged and designed such that the conveying device is pivotable at least about the horizontal axis; at least one second actuator arranged and designed such that the conveying device is pivotable at least about the vertical axis; characterized in that: at least one control device and at least one input device are provided, wherein movement of at least one first position of the conveying device can be specified at the input device, and the actuator can be controlled by means of the control device to cause the first position of the conveying device to perform the specified movement.
[0011] According to the present invention, a method for constructing a pavement or structure using a slipform paver includes at least one machine frame, at least one conveying device connected to the at least one machine frame, wherein the conveying device is pivotable relative to the machine frame at least about a horizontal axis and at least about a vertical axis, wherein at least one first actuator is capable of pivoting the conveying device at least about the horizontal axis, and at least one second actuator is capable of pivoting the conveying device at least about the vertical axis; characterized in that: movement of at least one first position of the conveying device is specified at at least one input device, and the actuator is controlled by means of a control device to cause the first position of the conveying device to perform the specified movement.
[0012] The present invention advantageously provides at least one control device and at least one input device, wherein movement of at least one first position of the conveying device is specified at the input device, and the actuator is controllable by means of the control device in such a way that the first position of the conveying device performs the specified movement.
[0013] According to the present invention, at least one first actuator is provided, which is arranged and designed such that the conveying device is pivotable at least about a horizontal axis. Furthermore, a second actuator is provided, which is arranged and designed such that the conveying device is pivotable at least about a vertical axis.
[0014] Since the movement of at least one first position of the conveying device can be specified by means of an input device, and the actuator can be controlled by means of a control device to perform the specified movement of at least one first position of the conveying device, the conveying device can be optimally positioned.
[0015] The first position can be formed by a point of the conveying device permanently stored in the machine control system. In this arrangement, the first position can be particularly preferably located at the first end or the second end of the conveyor.
[0016] However, the first position can preferably be selected or set by the operator.
[0017] Particularly preferably, multiple points along the extension of the conveyor can be stored in the control device, from which the operator can select which point to form a first position. This allows the operator to individually determine which position or point of the conveyor to perform a movement that can be specified by the operator.
[0018] In this arrangement, it is particularly advantageous if at least the first end and the second end of the conveying device are selectable. This allows the operator to determine, before inputting control commands, whether the first end or the second end of the conveying device is the first position of the conveying device to execute the specified movement according to the operator's control commands.
[0019] The operator can then designate the first end of the conveyor as the first position to facilitate the adjustment of the material loading position onto the belt conveyor. This helps in positioning the pick-up position relative to the loading vehicle.
[0020] If the operator selects the second end of the conveyor as the first position, he can optimally adjust the position of the material conveyed to the working device in order to optimize the loading of concrete into the mold.
[0021] In addition, other points along the extension of the belt conveyor can be selected by the operator as the primary position to allow for flexible positioning of the conveyor.
[0022] As an alternative to selecting a previously determined point along the extension of the conveyor, the control device can also be designed in a way that allows the operator to freely determine a first position along the longitudinal extension of the conveyor. This allows the operator to optimize the positioning of the conveyor in any given location under every operating condition.
[0023] The movement performed by the first position of the conveying device is a movement relative to at least one machine frame.
[0024] The decisive factor is that the movement of the conveyor's first position is directly specified by the input device, rather than by the movement of the actuator. The movement executed by the actuator is controlled based on an algorithm stored in the control device.
[0025] The stored algorithm takes into account the actuator geometry, axis, and the arrangement of the conveyor relative to the machine frame.
[0026] By means of a control device, the movement of a first position specified in the input device is converted into coordinated actuation of the actuator, so that at least one first position performs the specified movement.
[0027] At least one third actuator may also be provided, arranged and designed such that the conveying device is translatably movable at least in the first direction. In this design, depending on the embodiment, the conveying device may be translatably movable as a whole or only at one end of the conveying device in the first direction, which allows for extension of the length of the conveying device. Alternatively, both may be possible.
[0028] Precise control of these movements is achieved through control and input devices. The movement of the conveyor to a specific position is specified at the input device. The control device processes these inputs and accordingly controls the actuators, causing the conveyor to perform the desired movement at its first position. This arrangement allows for flexible adaptation to different construction site conditions. The combination of a pivotable conveyor, precisely controllable actuators, and user-friendly input devices, which can be used to specify the movement of at least one position of the conveyor, represents a substantial improvement in the user-friendliness and flexibility of slipform pavers.
[0029] A control device is provided, which is connected to an input device. The control device receives and processes input from the input device to control the movement of a conveying device. The control device can be connected to an actuator via an electrical or electronic interface and is capable of coordinating the control of the movement of the conveying device.
[0030] Movement of at least a first position of the conveying device can be specified at the input device. This means that the operator can input specific movement commands, which can be interpreted and executed by the control device. The input device can be connected to the control device via a communication interface to ensure smooth transmission of commands.
[0031] The actuator can be controlled by means of a control device in such a way that it performs a specified movement to a first position of the conveyor. This can be achieved by means of a precise interaction between the control algorithm and the actuator, which ensures that the conveyor performs the desired movement in a precise and reliable manner.
[0032] In addition, the control device can continuously monitor the position and movement of the conveying device, and it can also adjust the control commands accordingly to achieve the specified movement.
[0033] Specifying movement can be the direction of movement and / or the speed of movement and / or a predefined movement target.
[0034] The first position of the conveying device can be arranged at the first end of the conveying device or at the second end of the conveying device.
[0035] The second position of the conveying device can be arranged at the first end of the conveying device or at the second end of the conveying device.
[0036] The first position and the second position of the conveying device are a certain distance apart from each other. This means that if the first position of the conveying device is located at the first end, the second position of the conveying device is not located at the first end, and vice versa.
[0037] There may be at least one first collision zone that can be defined relative to the machine frame, wherein the actuator can be controlled by means of a control device in such a way that the conveyor cannot move into at least one first collision zone.
[0038] The collision zone can be an area within the moving zone. The moving zone can be a space relative to the machine frame, within which the conveyor can theoretically move, and needs to be determined by the design of the conveyor and the actuators that move the conveyor.
[0039] The collision zone can be an area in which the conveyor should not move. This zone can be, for example, an area where a collision between the conveyor and at least one object is possible. The object can be, for example, part of a slipform paver, such as, for example, the traveling mechanism. In this case, the object would actually be located within the collision zone. Alternatively, it can also be a theoretical hazard of colliding with an object. For example, on a roadway, there can be an area located within a moving zone where vehicles (e.g., on-site vehicles) or other objects can move. In this case, a specific collision zone can be defined where a collision could theoretically occur.
[0040] The position of the conveyor within the moving zone, particularly its position relative to the collision zone, can be determined based on the adjusted position of the actuator. The control device can be designed to issue a control signal once it establishes that the conveyor has entered a specific distance from the collision zone.
[0041] The machine frame can be arranged in at least one first collision area such that the actuator can be controlled by means of a control device to prevent the conveyor from colliding with the machine frame.
[0042] At least one second position of the conveyor relative to the machine frame can be specified at the input device, wherein the actuator can be controlled by means of a control device in such a way that the second position can be substantially maintained in the specified position relative to the machine frame.
[0043] In this arrangement, even if the first position of the conveying device performs the specified movement, the second position can be essentially maintained in the specified position.
[0044] In this arrangement, essentially remaining in a specific position can be understood to mean that at least one second position of the conveying device is preferably moved away from the specific position by no more than 50 cm, particularly no more than 25 cm, and especially preferably no more than 10 cm, relative to the machine frame. However, it is particularly preferred that at least one second position of the conveying device does not move away from the specific position at all relative to the machine frame.
[0045] Similar to the first position, the second position can also be a position that is permanently stored in the machine control system along the longitudinal extension of the conveyor.
[0046] For example, if the first end of the conveying device is designated as the first position in the control device, then in a preferred embodiment, the second end of the conveying device can be designated as the second position. If the second end of the conveying device is designated as the first position, then the first end of the conveying device can be designated as the second position.
[0047] However, the second position can preferably be selected by the operator.
[0048] Preferably, the second position can also be selected and determined from a plurality of points extending longitudinally along the belt conveyor. Therefore, the machine operator can select which points of the belt conveyor remain substantially stationary during movement at the first position. This makes positioning easier because the operator only needs to focus on controlling the point to be moved, selected as the first position, without having to consider the effects of movement at the second position.
[0049] Particularly preferred is that the operator stores paired points extending longitudinally along the longitudinal axis of the belt conveyor as a pair of first and second positions in the control system, and the operator can also select which point in the pair will be selected as the first and / or second position.
[0050] The operator can then select such a pair of points. The operator can then further select which point, as the first position, follows the movement specified at the operating device, and which point, as the second position, remains substantially in the specified position.
[0051] Such a pair of points can be formed, for example, by a first end and a second end of the conveying device. The operator can select the pair of points in a first step, then determine whether the first end or the second end of the conveying device is identified as a first position, and thus can subsequently be positioned using the operating device. The other end of the conveying device is then identified as a second position. The operator can now freely position the end of the conveying device identified as the first position, and the other end of the conveying device identified as the second position remains substantially in its position regardless of the free positioning of the first end. Therefore, the positioning of the respective ends of the conveying device is significantly simplified, as the influence of the adjustment operation on the other end of the conveying device no longer needs to be considered.
[0052] In principle, one-to-one pairs can also be stored only in the control system, and the operator only needs to select which of the two points is determined as the first position and / or which of the two points is determined as the second position.
[0053] Alternatively, the second position, which extends longitudinally along the conveyor, can also be determined independently of the first position.
[0054] In principle, it is also conceivable that the second position can be freely determined by the operator along the longitudinal extension of the conveying device.
[0055] The actuator can be a hydraulic, pneumatic, or electric actuator.
[0056] The conveying device can be directly or indirectly connected to the machine frame via at least a first parallelogram guide, wherein the conveying device can pivot about a horizontal or vertical axis by means of the first parallelogram guide.
[0057] The conveying device may be directly or indirectly connected to the machine frame via at least one first articulated joint, wherein the conveying device may pivot about a horizontal or vertical axis by means of the first articulated joint.
[0058] At least one third actuator may be provided, which can be arranged and designed such that the conveying device can translate in at least one first direction. In this design, depending on the embodiment, the conveying device may translate in the first direction as a whole or only at one end of the conveying device, which allows for an extension of the length of the conveying device. Alternatively, both may be possible.
[0059] The conveying device may include a transport conveyor.
[0060] A method may be provided for constructing a pavement or structure using a slipform paver, the slipform paver including at least one machine frame and at least one conveying device connected to the at least one machine frame, wherein the conveying device is pivotable relative to the machine frame at least about a horizontal axis and at least about a vertical axis, wherein at least one first actuator can pivot the conveying device at least about the horizontal axis and at least one second actuator can pivot the conveying device at least about the vertical axis, wherein movement of at least one first position of the conveying device is specified at at least one input device, and the actuator is controlled by means of a control device in such a way that the first position of the conveying device performs the specified movement.
[0061] A second position can be specified relative to the machine frame, wherein the actuator can be controlled by means of a control device in such a way that the second position can be maintained in the specified position relative to the machine frame.
[0062] At least one first collision area can be defined relative to the machine frame, wherein the actuator can be controlled by means of a control device in such a way that the conveying device does not move into at least one first area.
[0063] The machine frame can be arranged in at least one first collision area, such that the actuator can be controlled by means of a control device in such a way that the conveyor cannot collide with the machine frame. Attached Figure Description

[0075] Figure 10 This shows a slipform paver in a changed operating position. Detailed Implementation
[0076] 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.
[0077] 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 conveying device 6 is provided. The conveying 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 ground paving or structures. For example, the working device can be a concrete mold. The working device can be replaceable and can also be repositionable or extendable. The traveling device 4 can be connected to the machine frame in such a way that the traveling device 4 can change its position relative to the machine frame.
[0078] Figure 1 The image depicts a slipform paver 1, wherein the length of the longitudinal member 81 of the machine frame 2 is variable. Furthermore, the machine frame 2 includes a machine frame component 200, the length of which is variable in both the longitudinal direction 230 and the transverse direction 220. Different working devices 12 (e.g., concrete molds of different shapes) can be attached to the machine frame component 200. These can be positioned differently by means of the machine frame component 200.
[0079] The conveying device 6 can be connected to the machine frame 2 in such a way that the conveying device 6 can pivot relative to the machine frame at least about a horizontal axis and at least about a vertical axis. As depicted in the embodiments, the conveying device 6 can also translate relative to the machine frame in at least one first direction.
[0080] Materials can be picked up by means of conveyor 6 and transported to work equipment 12 for constructing paved roads or structures.
[0081] exist Figure 2The conveying device 6 is described in more detail, wherein material is picked up at a first end 8 and placed at a second end 10 into a working device 12 designed as a concrete mold.
[0082] A control device 62 is provided to control the actuator. The control device 62 is connected to an input device 82, which can be used to specify the movement of a first position 9 of the conveyor 6. The input device 82 allows the user to input the desired movement of the conveyor 6, whether in the form of a direction of movement, speed of movement, or a predetermined movement target.
[0083] The actuator can be controlled in such a way that the first position 9 of the conveying device 6 performs a specified movement. This is made possible by a control device 62, which receives signals from the input device 82 and forwards corresponding commands to the actuator.
[0084] The first position of the conveying device 6 can be any given position on the conveying device 6. As in the depicted embodiment, it can be, for example, located at the position of the first end 8, where material is loaded onto the conveying device. However, the first position of the conveying device 6 can also alternatively be located at the position of the second end 10.
[0085] Furthermore, the second position 11 of the conveyor 6 can be specified relative to the machine frame 2. The actuator can be controlled in such a way that the second position is held in the specified position relative to the machine frame 2.
[0086] The second position of the conveying device 6 can also be any given position on the conveying device 6. As depicted in the embodiment, the second position of the conveying device 6 can be, for example, the position at the second end 10, where material is conveyed into the working device 12 designed as a concrete mold.
[0087] In this way, for example, when changing the transport vehicle that provides the concrete to be placed, the first position 9 of the conveying device 6 can be moved to enable continuous loading, and at the same time, the material can be placed in the concrete mold 12 at the second position 11 of the conveying device 6 without changing its position.
[0088] Alternatively, if the first position 9 of the conveying device 6 is located at the position of the second end 10, the second position 11 of the conveying device 6 may also be located at the first end 8.
[0089] The input device 82 can be arranged separately from the control device 62, or the input device 82 and the control device can be designed as a single unit. The input device can be arranged on the slipform paver or separately from the slipform paver.
[0090] exist Figure 3The conveying device 6 is described in more detail below. The conveying device 6 includes either a belt conveyor or a transport conveyor 14, which... Figure 3 As shown in the diagram, the belt conveyor 14 and therefore the conveying device 6 can pivot about a horizontal pivot axis 19 by means of at least one first actuator 22. Furthermore, the conveying device 6 can pivot about a vertical pivot axis 36 by means of a second actuator 34. Additionally, the conveying device 6 can also translate in at least one first direction 16 by means of a third actuator 18. In this design, depending on the embodiment, the belt conveyor 14 can move as a whole or only one end of the belt conveyor 14 in the first translational direction 16, which allows for an extension of the belt conveyor's length. Alternatively, both may be possible.
[0091] Furthermore, the conveying device 6 is arranged on a parallelogram guide 106, which can be used by means of... Figure 3 An additional actuator 24, not depicted in the text, is used to regulate the entire conveying device 6. This will be referred to... Figure 7 To explain in more detail: The parallelogram guide 106 is arranged on the machine frame 2.
[0092] Figure 4 It shows that according to Figure 3 In one embodiment, the conveying device moves in the translation direction 16, wherein the conveying device as a whole has already moved in the translation direction 16.
[0093] In addition, Figure 4 The diagram depicts at least a first actuator 22 that enables the conveyor 6 to pivot about a pivot axis 19, which is preferably a horizontal axis. In this design, the pivot axis 19 is preferably positioned below the belt conveyor 14. As depicted in the embodiment, the pivot axis 19 may be positioned at the upper third of the conveyor 6. In another preferred embodiment, the pivot axis 19 may be positioned in the middle third of the region of the conveyor 6. In the depicted embodiment, the depicted first actuator 22 is mounted on a connecting element 100 to pivot about a pivot axis 102. The connecting element 100 is arranged on a parallelogram guide 106. The first actuator 22 is also connected at a second end to the conveyor 6 to pivot about a pivot axis 103. The conveyor can also be translated along axis 36 manually or by means of an additional actuator.
[0094] Figure 5A bottom view of this embodiment is shown. However, for clarity, the belt conveyor is not depicted. This view shows at least one first actuator 22, at least one second actuator 34, and at least one third actuator 18. The second actuator 34 can cause the conveying device 6 to pivot about a vertical pivot axis 36. The pivot axis 36 preferably intersects the belt conveyor. Furthermore, the pivot axis 36 may extend through the pivot axis 19. This can also be seen from... Figure 4 It is inferred that, in the depicted embodiment, the second actuator is connected at a first end to a parallelogram guide 106. At a second end, the second actuator 34 is pivotally connected to a connecting link 108, which in turn is connected to a hollow column 110, which is connected to the conveying device 6. By operating and extending or retracting the second actuator 34, the hollow column 110 and thus the conveying device 6 can pivot about a pivot axis 36.
[0095] In addition, Figure 5 An optional additional actuator 24 is also depicted. This actuator 24 can be used to adjust the entire conveyor 6 using the parallelogram guide 106. The parallelogram guide 106 is arranged on the machine frame 2.
[0096] If the machine does not include the optional additional actuator 24 and parallelogram guide 106, the axis 36 can also be arranged on the machine frame.
[0097] Because the conveying device can move and position flexibly within the moving area, at least by means of actuators 22, 18, 34, 24, materials can be reliably transported to the working device by means of the conveying device 6. The pick-up position of the material being conveyed to the conveying device 6 is flexible in this design, as is the position of the material being conveyed to the working device 12.
[0098] As an alternative to the parallelogram guide 106, axis 36 can also be arranged to be linearly movable, preferably movable in the transverse direction of the machine perpendicular to the operating direction A.
[0099] Within the meaning of this invention, "horizontal" does not necessarily mean horizontal relative to the ground surface, but rather horizontal relative to the plane defined by the longitudinal and transverse axes of the machine frame.
[0100] In order to control the movement of at least one first position 9 of the conveying device 6, a control device 62 is provided (in... Figure 2 (as depicted in the illustration). As explained above, the first position of the conveying device 6 can be any given position on the conveying device 6. As in the illustrated embodiment, it can be, for example, at the position of the first end 8, where material is loaded onto the conveying device.
[0101] Control device 62 is connected to actuators 22, 18, 34, and 24, and controls the movement of actuators 22, 18, 34, and 24 based on inputs made via input device 82. The input device is also... Figure 2 The diagram is schematically depicted. Input device 82 can be used to specify movement of at least one first position of the conveying device 6. Control device 62 ensures that actuators 22, 18, 34, 24 perform the specified movement, causing the first position of the conveying device 6 to perform the desired movement and / or reach the desired position. If additional actuators are provided, control device 62 can also control said additional actuators to control the first position 8 of the conveying device 6.
[0102] Figure 6 Showing according to Figure 4 The conveying device is in an adjustable position. Figure 6 In, with Figure 4 In comparison, at least the first actuator 22 has been adjusted. Figure 6 A moving zone 40 is also depicted. In this arrangement, the moving zone 40 is the space in which the conveying device 6 can move by moving at least the first actuator, the second actuator, and the third actuator. Therefore, it is the space in which the conveying device 4 can theoretically move. The moving zone 40 is defined relative to the machine frame. If the slipform paver and therefore the machine frame moves forward, the moving zone 40 will also move forward. The moving zone 40 must be determined by the design of the conveying device and the actuators that move the conveying device. Figure 6 The moving area is depicted only in a side view.
[0103] The collision zone 60 can now be defined within the moving area. The collision zone 60 is the area within the moving area 40 where the conveyor 6 should not move. The collision zone 60 can be, for example, an area where the conveyor 6 may collide with the machine frame 2 or the traveling device 4, or at least any other object.
[0104] Figure 7 A top view of the conveyor 6 is shown. However, for clarity, the belt conveyor 14 is not shown. The top view depicts an optional additional actuator 24. The additional actuator 24 can pivot the entire conveyor 6 in parallel. In this embodiment, the optional additional actuator 24 pivots the conveyor by means of a parallelogram guide 106. Figure 7 The figure depicts two links 26 and 28, each pivoting about rotation axes 30 and 32.
[0105] The movement zone 40 and the optional collision zone 60 are in Figure 7 The top view depicts the area 60. However, the moving area 40 and the collision area are only depicted in a specific horizontal plane. It is not possible to depict the spatial extension of the collision area 60 and the moving area 40 outside the plane in this top view.
[0106] The conveying device 6 can move within a movement zone 40 defined relative to the machine frame 2 by means of at least one first actuator 22, at least one second actuator 34, and at least one third actuator 18. As depicted in the embodiment, the conveying device 6 can also optionally move within the movement zone 40 defined relative to the machine frame 2 by means of at least one third actuator 18. The movement zone 40 is in... Figure 6 and Figure 7 As depicted in the diagram. If additional actuators, such as, for example, additional actuator 24, are provided, the movement zone 40 becomes a space in which the conveying device 6 can be moved by moving the first actuator 22, the second actuator 34, the third actuator 18, and the additional actuator 24. This arrangement does not preclude the provision of more than one additional actuator. For the purpose of defining the movement zone, all degrees of freedom of the conveying device and therefore all actuators involved in adjustment operations must be considered.
[0107] Furthermore, an optional collision zone 60 is also depicted in the moving area 40. The optional collision zone 60 is the area within the moving area 40 where the conveyor 6 should not move. The collision zone 60 may be, for example, an area where the conveyor 6 might collide with the machine frame 2 or the traveling device 4, or at least any other object. Generally, the collision zone defines the portion of the moving area where the conveyor 6 should not move.
[0108] exist Figure 8 The control device 62 and the input device 82 are described in more detail.
[0109] The depicted control device 62 preferably includes a storage device 80. The control device 62 may also be connected to an input device 82.
[0110] The input device 82 can be used to specify the movement of at least one first position of the conveying device 6. The provided actuator can be controlled by means of the control device 62 in such a way that the first position 8 of the conveying device 6 performs the specified movement.
[0111] Sensor signal 84 can also be transmitted to control device 62. Sensor signal 84 may be, for example, a position signal of conveying device 6. Additional sensor signal 86 can also be transmitted to control device 62. The additional sensor signal 86 may be a sensor signal related to the position and / or size of the working device and / or traveling device 4. Control device 62 can issue at least one control signal 88, which will be described in more detail below.
[0112] The input device 82 can be used to specify movement of at least one first position of the conveying device 6. The provided actuator can be controlled by means of the control device 62 in such a way that at least the first position 8 of the conveying device 6 performs the specified movement.
[0113] For this purpose, control signal 88 can be transmitted, for example, to an actuator, which controls the actuator in such a way that at least one first position of the conveying device performs a movement specified at the input device.
[0114] The specified movement can be the direction of movement and / or the speed of movement and / or a predefined movement target.
[0115] To clarify the operating principle of the slipform paver according to this utility model and the method according to this utility model, Figure 9 and Figure 10 The slipform paver is again depicted in a largely schematic manner and using only the relevant assembly. In the depicted embodiment, the conveying device 6 includes either a belt conveyor or a transport conveyor 14.
[0116] Figure 9 A slipform paver 1 is shown operating in the direction of operation A. The slipform paver receives concrete to be paved from a supply vehicle 400 via a supply device 41 at the first end of a conveying device 6. The concrete is then conveyed via a belt conveyor 14 to a second end 10, where it is placed in a concrete mold 12.
[0117] The second supply vehicle 400' with the second supply device 41' in Figure 9 The image is depicted only with dashed lines. When the concrete supply provided by the first supply vehicle 400 has been used, it is necessary to change the supply vehicle. Due to the expected, ideal, uninterrupted concrete supply, the second supply vehicle 400' can approach the slipform paver 1 parallel to the first supply vehicle 400.
[0118] like Figure 2 As depicted, the first end 8 of the belt conveyor 14 is designated as a first position 9, and the second end 10 of the belt conveyor 14 is designated as a second position 11. In this context, it is irrelevant whether the determination is stored in the control system or is made in advance by the machine operator.
[0119] In order to switch the supply of concrete from the first supply vehicle 400 to the second supply vehicle 400', it is now necessary to position the first end 8 below the supply device 41', where the concrete is picked up by the slipform paver. For this purpose, the operator can make a control input at the input device 82, which initiates the first position 9 of the conveyor 6 to move to the left as seen in the direction of travel; in this embodiment, the first position 9 of the conveyor 6 is located at the first end 8. The control unit 62 now coordinates the actuation of the actuators 22, 18, 34, 24 in such a way that the first position 9 of the conveyor 6 pivots to... Figure 10 The second position 11 of the conveying device (located at the second end 10 in this embodiment) is positioned below the second supply device 41' as depicted, while the second position 11 of the conveying device is positioned above the concrete mold 12 to ensure that concrete is continuously placed into the mold.
[0120] because Figures 3 to 7 The arrangement of actuators depicted in the figure indicates that moving just one actuator is insufficient for this purpose; coordinated movement is necessary. In the depicted example, the links 28 and 26 of the parallelogram guide 106 ( Figure 9 and Figure 10 (Not depicted in the text) by means of actuator 24 ( Figure 9 and Figure 10 (Not depicted) Pivoting to move axis 36 to the left as seen in the direction of travel. However, actuator 18 must also be actuated simultaneously to move the pickup position 8 along the longitudinal axis of the belt conveyor 14 toward position 10. In addition, it may be necessary to adjust the inclination of the belt conveyor 14 via actuator 22, or to pivot the conveyor via actuator 34.
