Description

Technical Field

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

[0002] Slipform pavers are known, for example from DE 19957048. Figure 1 As shown in . Slipform pavers are used to build paved surfaces or structures made of concrete. Slipform pavers usually comprise at least one machine frame and at least two travel devices, wherein the at least two travel devices are each connected to the machine frame via at least one height adjustment device. In addition, at least one motor drive system is provided, which drives the at least two travel devices. The slipform paver is thus a self-propelled slipform paver.

[0003] Furthermore, at least one working device is provided for the construction of a paved road surface or structure. Furthermore, at least one conveying device is provided for transporting concrete to the at least one working device. With existing slipform pavers, there is often the problem that the conveying device cannot be adequately cleaned. Utility Model Content

[0004] The object of the invention is therefore to create a slipform paving machine in which the cleaning of the conveying device is simplified.

[0005] The invention advantageously provides that at least one cleaning device is arranged on the conveying device for cleaning the conveying device.

[0006] Arranging the cleaning device on the transport device means that the cleaning device can be arranged directly or indirectly on the transport device.

[0007] Since the cleaning device is arranged on the conveying device, the cleaning quality can be improved.

[0008] The conveying device can be a belt conveyor or a screw conveyor.

[0009] Particularly when cleaning screw conveyors, a problem that has hitherto existed in the prior art is that not all areas can be adequately cleaned.

[0010] A guide device may be arranged on the transport device, on which the cleaning device is movable along the transport device, wherein the guide device preferably comprises a guide rail.

[0011] Due to the guide device which is movable along the conveying device, it can be ensured that the conveying device can be cleaned uniformly everywhere.

[0012] The guide device is preferably arranged outside the conveying area.The conveying area is preferably the area in which the material is transported on the conveying device.

[0013] The cross-sectional profile of the guide rail can assume any given shape. The guide rail can be, for example, a tube. Alternatively, the cross section of the guide rail can also be a rectangular profile. Any other type of cross-sectional shape can also be provided. It must only be possible to move the guide device along the guide rail.

[0014] For example, provision can be made for the cleaning device to be moved along the guide device in the manner of a carriage.

[0015] The conveying device may comprise a first end and a second end, the concrete being unloadable into or onto the first end and the concrete being unloadable at the second end into or in front of the working device, wherein a transport direction of the conveying device extends from the first end to the second end and a longitudinal axis of the conveying device preferably extends substantially parallel to the transport direction.

[0016] Thus, concrete is fed onto the conveying device at a first end and transported by the conveying device to a second end, where it is unloaded into or in front of the working device.

[0017] The working device may be, for example, a concrete mold. The concrete mold may also be referred to as an offset mold or an embedded mold.

[0018] A drive device may be provided, by which the cleaning device can be moved along the guide device. The drive device may be, for example, a cable winch. Alternatively, the drive device may also be, for example, a chain drive or a toothed belt drive or the like. The drive device may be a hydraulic drive. For example, an electric drive device may also be provided as an alternative.

[0019] The driving device for driving the cleaning device is preferably completely independent of the motor drive system for driving the traveling device. According to the utility model, at least a motor drive system for driving at least two traveling devices is provided. The motor drive system can be any type of driver that can be used to drive at least the traveling device. The motor drive system can be a hydraulic drive, an electric drive and / or a pneumatic drive and / or include an internal combustion engine. The motor drive system can also include, for example, an internal combustion engine, which drives, for example, a hydraulic drive, which in turn drives, for example, the traveling device.

[0020] The cleaning device may comprise at least one spray device.

[0021] The at least one injection device may be an injection nozzle, which may preferably be a high-pressure nozzle.

[0022] For example, a high pressure pump may be provided that pressurizes the fluid and then delivers the fluid to the spray device in order to clean the delivery device.

[0023] A fluid tank may also be provided, for example, from which the fluid is transported under high pressure to the spraying device.

[0024] The at least one spray device can be adjustable and / or pivotable and / or displaceable relative to the base element of the cleaning device.

[0025] Therefore, the spraying device can adopt different positions and alignments relative to the basic element of the cleaning device. This allows, for example, spraying in different directions and thus can improve the cleaning result.

[0026] The cleaning device may comprise a plurality of spray devices. The plurality of spray devices may be jointly or independently adjustable and / or pivotable and / or movable relative to a base element of the cleaning device.

[0027] The delivery device can be cleaned better by means of a plurality of spray devices.

[0028] At least one actuating device may be provided, by means of which the at least one spraying device is adjustable and / or pivotable and / or movable.

[0029] At least one control device may be provided, wherein at least one actuating device and / or drive device and / or injection device may be controlled by the control device, wherein the control device may be controlled automatically or manually.

[0030] Thus, the control device can control an actuating device which adjusts and / or pivots and / or moves at least one spray device or a plurality of spray devices. Additionally or alternatively, a drive device for driving the cleaning device can also be controlled by the control device. Furthermore, additionally or alternatively, at least one spray device can also be controlled by the control device.

[0031] If it is provided that the control device is automatically controllable, a previously specified program may be stored, for example, based on which the control device controls the actuation device and / or the drive device and / or the injection device.

[0032] The control device can be remotely controllable.For example, a joystick can also be provided, which can be used to control the actuating device and / or the driving device and / or the ejecting device, for example.

[0033] At least one injection device can be connected to at least one injection line, wherein the injection line can be rotated together with the at least one injection device about a first rotation axis, wherein the at least one injection device is arranged with a certain offset relative to the rotation axis and the injection direction is aligned so that the injection action causes the injection device to rotate about the rotation axis.

[0034] The injection device is preferably arranged with a certain offset relative to the rotation axis. In addition, the injection direction is preferably aligned so that it neither extends in the radial direction nor extends parallel to the rotation axis. The injection direction is thus at least partially tangentially aligned so that the injection causes a rotation around the rotation axis.

[0035] In this way, the spraying device can rotate during spraying, wherein the spraying device itself causes the rotation by the spraying action. Through the rotation, different points of the conveying device can be reached, and thus the cleaning can be improved.

[0036] At least two injection devices can be connected to at least one injection pipeline, wherein the injection line can be rotated together with the at least two injection devices around a first rotation axis, wherein the at least two injection devices are arranged on opposite sides relative to the rotation axis and are arranged relative to the rotation axis with a certain offset, and the injection direction is aligned so that the injection action causes the injection device to rotate around the rotation axis.

[0037] Since two spraying devices are provided which are arranged on different sides of the rotation axis and the spraying directions are aligned accordingly, the forces acting on the rotation axis are balanced.

[0038] At least one hose can be provided which is connected to the cleaning device via a first hose end and by means of which fluid can be supplied to the cleaning device, wherein the first hose end is movable together with the cleaning device.

[0039] This allows fluid to be supplied to the cleaning device and thus to the spraying device.

[0040] The second hose end is preferably connected to a pump which in turn is preferably connected to the fluid tank.

[0041] The hose can be wound up and unwound on a reel or, if the cleaning device is movable, the hose can be guided in an energy chain. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The different operations, steps or algorithms that the control device can perform within the meaning of the present invention can be directly embodied in, for example, hardware, a computer program (such as a software module executed by a processor) or a combination of the two. The computer program can be located in, for example, a RAM memory, a flash memory, a ROM memory, an EPROM memory, an EEPROM memory, a register, a hard disk, a removable medium or any other form of computer-readable medium known in the prior art. For example, an example of a computer-readable medium can be coupled to a processor so that the processor can read information from a memory / storage medium and can write information thereon. Alternatively, the medium can also be integrated into the processor. The processor and the medium can be located in, for example, an application-specific integrated circuit (ASIC). The ASIC can be located in a user terminal device. Alternatively, the processor and the medium can be located in a user terminal device as discrete components.

[0061] The term "processor" as used herein may refer to at least a general purpose or special purpose processing device and / or logic, as will be understood by those skilled in the art, including but not limited to a microprocessor, a microcontroller, a finite state machine, etc. A processor may also be implemented as a combination of computer devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, a combination of one or more microprocessors and a DSP core, or other such configurations.

[0062] The cleaning device 22 comprises at least one spray device 26, which Figure 2 The conveyor device 2 can be cleaned by means of a spray device 26 , wherein the cleaning device 22 can be moved along the conveyor device 2 and thus the entire area of ​​the conveyor device 2 can be cleaned.

[0063] Figure 2 A reel 28 is also depicted, which can be used to reel in the hose. The hose, not depicted, can be connected to the cleaning device via a first hose end and can move with it. When the cleaning device 22 moves, the hose can be reeled on or unreeled from the reel 28, respectively, and furthermore, the second hose end can be connected to a fluid reservoir, so that the cleaning device 22 is always supplied with fluid for cleaning.

[0064] Figure 3 Shown according to Figure 2 The cleaning device 22 of the present invention is shown in Figure 1. This is only one embodiment. In this embodiment, a plurality of spray devices 26 arranged adjacent to each other are provided. The spray devices 26 are connected to a spray rod 46. The spray rod 46 is connected to the base element 24 of the cleaning device 22. The spray rod 46 can be pivoted relative to the base element 24 together with the spray devices 26.

[0065] The spray device 26 can spray the cleaning fluid from the spray device 26 in the form of a spray cone 44. The spray device 26 is preferably a nozzle, in particular a high-pressure nozzle. In the depicted embodiment, the cleaning device 22 has been implemented in the design of a carriage. The carriage includes rollers 48, which can be used to move the cleaning device 22 along the guide rails 33, 34.

[0066] exist Figure 4 An alternative embodiment is depicted in FIG. The injection device 26 is attached to the base element 24 and the base element 24 can be adjusted in the slot 52. To this end, the nut 51 can be loosened and the injection device 26 can then be adjusted relative to the base element 24. For the sake of clarity, in Figure 4 Not all jets and not all nuts are shown.

[0067] Figure 5 Shows the view from below Figure 4 5. A slot 52 is also depicted therein. The injection devices 26 are also connected to injection lines 54. The injection lines 54 are each rotatable together with two injection devices 26 about a first rotation axis 56, wherein the respective injection devices are arranged on opposite sides relative to the first rotation axis 56. The injection devices 26 are arranged with a certain offset relative to the rotation axis 56, and the injection directions of the respective injection devices 26 are aligned such that the injection devices 26 rotate about the rotation axis 56 due to the injection action.

[0068] exist Figure 5 It is evident how the spray cones 44 are aligned with each other. The spray direction of the spray cone 44 thus has at least a tangential portion relative to the axis of rotation, which causes the spray line 54 and the spray device 26 to rotate about the axis of rotation 56 due to the spraying of the spray device 26.

[0069] Figure 6 Another alternative embodiment is shown. In this embodiment, at least one injection device 26 is depicted, which is arranged to be movable relative to the base element 24.

Thus, the injection device 26 can be pivoted about the pivot axis 62 by moving the actuator 58 and by means of the connecting element 60, and can thus be adjusted relative to the base element 24.

[0070] Figure 7A further embodiment is shown. In this embodiment, an actuator 58' is also provided, which can adjust the spraying device 26 via a connecting element 60'. In this embodiment, a spraying line 54 is also provided, on which two spraying devices 26 are arranged and can be rotated about an axis of rotation 56. Furthermore, the spraying line 54 can be adjusted relative to the base element 24 together with the spraying devices 26 via the connecting element 60' and the actuator 58'.

[0071] Figure 7 Also depicted is the trough 42. A strip 64 is arranged in the trough 42. The strip 64 ensures that the concrete conveyed in the trough by the screw conveyor does not overflow at the sides, but is diverted back into the center of the trough.
