Description

Technical Field

[0001] The invention relates to a self-propelled ground processing machine, comprising a machine frame, a travel mechanism carrying the machine frame, a travel drive, and a ground processing device configured for processing ground, wherein the ground processing machine has a control device for controlling the operation of the ground processing machine, wherein the control device has an operating module, the operating module has a plurality of selectively actuable operating elements, the actuation of the operating elements being suitable for changing the operating state of the ground processing machine, wherein the control device has an at least two-part housing, the operating module being accommodated in the housing, wherein the housing has a lower cover and an upper cover, the lower cover and the upper cover being movable relative to each other between a closed position and an open position, wherein the operating elements of the operating module accommodated in the housing are accessible in the open position of the housing. The housing and at least one operating module together form the operating device. Background Art

[0002] In the open position of the housing, the operating elements are accessible to a greater extent than in the closed position of the housing. This can be achieved in that the operating elements are more accessible in the open position of the housing than in its closed position and / or that the operating elements can be accessed with less access effort in the open position of the housing than in its closed position. Preferably, most of the operating elements, particularly preferably all of the operating elements, are not accessible in the closed position of the housing.

[0003] Such a ground processing machine is known, for example, from EP 3 524 461 A1. Road milling machines, recycling machines and surface miners are listed as possible ground processing machines by way of example. In the closed position, the upper and lower covers completely conceal the operating module accommodated in the housing in order to protect it from sabotage attacks. Such sabotage attacks can sometimes occur when the ground processing machine is parked overnight at a construction site and a person with sabotage intent enters the construction site.

[0004] In the known operating device consisting of a housing and an operating module, the operating module is firmly anchored in the lower cover and can be completely covered by the upper cover in the closed position. In the open position, the upper cover is completely detached from the lower cover of the known operating device, raised and can be retracted away from the lower cover during the operating period of the ground working machine. The known upper cover has a substantially planar plate shape with a few stiffening ribs.

[0005] Based on this prior art, the object of the present invention is to provide an operating device consisting of a housing and an operating module with improved adaptability to different operating situations during operation of the ground working machine while maintaining the anti-vandalism protection as before when the ground working machine is not in use, so as to also better support the work of the machine operator working at the ground working machine.

[0006] A wireless operating device for a vehicle component is known from US 2015 / 0321597 A1, whose portable housing has a lower cover and an upper cover and an operating module arranged therein which can be removed if desired. The operating module can only be connected to the lower cover. The upper cover is pivotally connected to the lower cover. The known operating device can be arranged at the belt of the machine operator or in the cab of the vehicle via a separate bracket.

[0007] From US 7,953,517 B1 and US 10,069,284 B1, operating units for controlling irrigation devices are known. Each operating unit is accommodated in a plastic housing having a lower cover and an upper cover pivotably fixed to the lower cover. The operating device itself is connected to the housing so that it can be pivoted relative to the housing. The pivot axis of the housing and the pivot axis of the operating device are parallel or colinear with each other. Summary of the invention

[0008] According to the invention, the above-mentioned object is achieved by the self-propelled floor working machine mentioned at the beginning, wherein the operating module can be separated from the housing and can be arranged on the housing, wherein the operating module can be arranged in a ready-to-operate manner on each of the upper and lower housings.

[0009] Here, "in a ready-to-work manner" means that when the ground working machine is in a ready-to-operate state with the connected operating module, the operating elements are accessible as intended for the machine operator who controls the ground working machine. At least some, preferably all, of the operating elements of the operating module are connected to a data processing device of the control device in terms of signal transmission, so that their actuation causes a change in the state of the functional devices of the ground working machine in a predictable manner. Thus, the actuation of the operating elements of the operating module can control different actuators of the ground working machine, for example in order to move the ground working machine by means of a travel drive and / or to change the movement direction of the ground working machine by operating the running gear during movement and / or in order to control the operation of the ground working device, to name just a few examples.

[0010] Although the operating module can also and usually is accommodated in a cut-out manner in one of the two covers, the housing does not only serve to transport the operating module between the stowage location and the location of use. Rather, the housing serves to securely anchor the operating module in the working area of ​​the machine operator of the ground working machine in a ready-to-operate state and preferably also in a stationary state when the ground working machine is at rest in a cut-out manner.

[0011] Depending on the type and scope of floor processing of the floor processing machine, the operating device consisting of the housing and the operating module can be arranged at different locations of the floor processing machine, wherein the floor processing machine can perform the floor processing due to the floor processing device arranged there. The floor processing machine preferably has an operating station, at which the machine operator stays at least during the operation of the floor processing machine to control the floor processing machine. Therefore, the operating device is preferably arranged at the operating table, particularly preferably within the reach of an adult around a possibly provided operating seat and / or within the reach of an adult standing on the floor of the operating table.

[0012] The operating module is preferably arranged in one of the upper and lower covers, such that the operating module is physically connected to the cover and is held at the cover.

[0013] The housing preferably has a housing volume, in which the operating module is accommodated in the case of the intended arrangement in the cover, wherein the housing volume is surrounded by the housing in the closed position. The housing can thus protect the operating module from being accessed from the outside in the closed state. An exception to the closed surrounding of the housing volume by the housing is that a through-opening can be formed, which can be provided at the housing in order to realize a connecting cable for transmitting signals and / or energy between components of the ground processing machine and the operating module.

[0014] The basic arrangement of the operating module in each of the upper and lower covers provides two different arrangement locations for arranging the operating module. Depending on the location where the machine operator is located during ground processing or also during a single driving operation of the ground processing machine, he can arrange the operating module in a ready-to-work manner in the upper and lower covers that is closer to his location, and thus remain at his location or only slightly and / or briefly leave the location in order to control the operation of the ground processing machine.

[0015] In order to protect the operating module without having to transfer it after the end of the work shift and after the ground processing machine has been switched off, it is preferably provided that the operating module can be arranged on the respective inner side of the upper or lower cover or at least arranged during operation of the ground processing machine. The operating module can then be retained in the housing by placing the housing in its closed position, independently of whether the operating module is actually currently arranged in the upper or lower cover, in order to prevent undesired access from the outside.

[0016] Preferably, the operation module may be arranged only at the inner side of the upper cover and at the inner side of the lower cover, respectively, or at the inner sides of the covers of the upper cover and the lower cover, respectively, which are selected for arrangement.

[0017] For the avoidance of any doubt, it should be clear that the inner sides of the upper and lower hoods are those sides of the mentioned hoods which are opposite one another and / or point towards one another in the closed position of the housing.

[0018] In order to realize that each of the upper cover and the lower cover configured to accommodate the operating module can not only hold the operating module itself, but also surround and shield the operating module at the side that does not need to be touched by the machine operator for operation, according to a preferred improved form of the present invention, each of the upper cover and the lower cover has a concave inner side configured to accommodate the operating module. The inner sides of the upper cover and the lower cover are configured to accommodate the operating module.

[0019] In order to make it easier to arrange the operating module in one of the upper and lower covers in a way that minimizes errors, the inner sides of the upper and lower covers and the outer sides of the operating module, which are opposite the corresponding cover inner sides in the operationally ready state, are preferably designed to be complementary. If the cover inner sides taper from the cover edge to the cover bottom, i.e. the net area enclosed by the corresponding cover inner side decreases when approaching the cover bottom from the cover edge, an advantageously short setup time of the operating device can be achieved by using the self-centering effect of the cover selected for the arrangement of the operating module.

[0020] Here, the cover edge is the edge of the upper cover and the lower cover which delimits the opening face of the respective cover radially outwardly through which the operating module is inserted into the respective cover. In the closed position of the housing, the edges of the upper cover and the lower cover are closer to each other. The covers are preferably superimposed in their approach direction so that in the gap formed between the upper cover and the lower cover, it is more difficult to pry the housing out of the closed position by the intervention of a tool.

[0021] Preferably, the sections of the outer side of the operating module which are surrounded by the upper or lower cover in the ready-to-operate state of the operating module taper in a complementary manner from the operating panel carrying the operating elements to the bottom of the operating module which is located at a certain distance from the operating panel. Preferably, in the ready-to-operate state of the operating module accommodated in the corresponding cover, at least the sections of the outer side of the operating module and the inner side of the operating simulation are in contact with each other. This can promote the above-mentioned preferred centering effect.

[0022] In principle, the cover edge can have any desired shape. It is advantageous in terms of manufacturing technology, while making good use of the installation space, if the cover edge of each cover preferably has a polygonal, preferably approximately rectangular or rectangular shape, which preferably has at least, particularly preferably exactly four straight edge sections, of which two in each case extend parallel to one another in pairs. As is typical for a rectangular shape, different pairs of parallel edge sections enclose a right angle to one another. In order to avoid injuries, the shape of the cover edge particularly preferably has rounded or inclined corners. This is indicated by the term "approximately rectangular".

[0023] The cover edges of the upper and lower covers are preferably designed to be complementary, so that in the closed position, the housing reliably surrounds the housing volume and is shielded from the external environment. The corresponding cover edges of the upper and / or lower covers are preferably substantially planar. The cover edges of the upper and lower covers are preferably planar at least at 75% of their circumference. For example, due to the preferred design or arrangement of the hinge, a deflection is obtained, which connects the upper and lower covers in a pivotable manner relative to each other. In order to form a mechanically particularly stable hinge, the projections arranged at a certain distance from each other can be arranged in a zigzag manner at the upper and lower covers, wherein the projections of the upper and lower covers are arranged offset relative to each other in the direction of their spacing, so that the projections of the upper and lower covers are in a meshing form-fitting engagement with each other in the formed hinge. The metal rod extending in the direction of the spacing of the projections of the upper and lower covers can then form a stable hinge axis of the hinge.

[0024] The upper and / or lower shell can be produced by injection molding with advantageous structural freedom, for example from foamed polyurethane or from styrene copolymers which are valuable for their high impact resistance, such as acrylonitrile-butadiene-styrene copolymers (ABS) or from blends of such ABS copolymers with another plastic, such as polyamide or polycarbonate. The plastic used to form the upper and / or lower shell can be filled with particles and / or fibers, in particular glass fibers, to increase its strength.

[0025] The inner side of the upper and / or lower cover can have a shell bottom with a mainly plane surface, in order to simplify the arrangement of the corresponding shell on a flat base. In case of doubt, this means that the inner and / or outer surface parts of the cover bottom are designed to be plane. Therefore, the planar outer part of the cover bottom can be used as a support surface for the cover on the base. In addition or as an alternative, the planar inner part of the cover bottom can be used as a support surface for supporting the bottom of the operating module. Preferably, the mainly plane cover bottom is inclined about an inclination axis relative to the substantially planar cover edge. As a result, side walls, for example side walls arranged away from the machine operator when the operating module is in the operating state, can extend further from the operating panel of the operating module than side walls arranged closer to the machine operator and opposite to the side walls arranged farther away. A certain degree of glare protection for the operating panel and its label or display surface can be achieved in this way.

[0026] Alternatively or additionally, by the described inclination of the hood edge and the hood bottom, the operating panel is completely accommodated in the hood in a manner that is more inclined toward the machine operator than it would be if the housing were mounted at a control console or at another location on the floor processing machine. This simplifies the accessibility of the operating surface for the machine operator in the open housing position. Preferably, the operating module is arranged in a ready-to-operate manner between the side wall disposed farther away and the side wall disposed closer.

[0027] In order to achieve the self-centering effect that is advantageously created, in a preferred development of the invention, the area of ​​the cover bottom can be smaller than the area of ​​the opening enclosed by the cover edge. However, due to the preferred configuration of the main plane of the housing bottom, it is possible to ensure that the cover is more reliably supported on the support base and that the cover is more reliably fixed on the support base.

[0028] The side walls extending from the cover edge to the cover bottom are inclined relative to a perpendicular midline perpendicular to the opening surface surrounded by the cover edge and / or relative to a perpendicular midline of a surface perpendicular to the cover bottom in order to provide the concavity of the inner side of the upper cover and the lower cover. Preferably, the side walls of the upper cover and the lower cover that are opposite to each other relative to at least one of the aforementioned perpendicular midlines are also inclined toward each other in the direction of the respective bottom, like the outer wall of the operating module extending between the operating panel and the operating module bottom.

[0029] The inclination of the side walls and / or outer walls can be changed once or multiple times in the direction toward the corresponding bottom, so that the side walls and / or outer walls can be curved at least in sections around a curvature axis or bent around a bending axis, wherein the curvature axis or the bending axis can, on the one hand, for example, extend parallel to or obliquely to the corresponding bottom and operating module of the observed component of the upper or lower cover and / or can extend parallel to the edge of the corresponding cover and the operating panel.

[0030] In principle, it should not be excluded that the upper cover of the housing can be completely lifted from the lower cover and can be arranged and anchored in a detachable manner as desired away from the lower cover on a base provided for this purpose on a support surface connected to the machine frame. Preferably, the upper cover is permanently connected to the lower cover in a captive manner. In a continuation of the preferred embodiment, the upper cover and the lower cover are preferably able to pivot relative to each other about a virtual pivot axis. Preferably, a pivot joint between the upper cover and the lower cover, such as the above-mentioned hinge, which provides the pivotability, forms a particularly preferably unique permanent connection between the two covers. The virtual pivot axis can be realized by a physical pivot axis or by other connecting mechanisms known to a person skilled in the art, which just allow a rotational movement freedom of the connected components.

[0031] In most cases, the ground working machine moves in a forward direction along its rolling axis extending in the longitudinal direction of the machine during its intended ground working operation. This does not exclude curved movement trajectories around curves. The rolling axis is then usually a tangent to the current curved movement path of the ground working machine or is located in the vicinity of this tangent. Therefore, the operating module can preferably be arranged in an upper or lower cover at the ground working machine in a selective manner, so that the operating module can be located in front of the machine operator at least in the forward direction during the operation of the ground working machine. In the preferred arrangement, the reading direction of any Latin character markings on the operating elements on the operating panel extends in the transverse direction of the machine, i.e. along the pitch axis of the ground working machine.

[0032] In the preferred arrangement of the operating device, the virtual pivot axis runs between the upper and lower cowlings in a plane having an angle of no more than 30°, preferably no more than 20°, to the roll axis and / or the yaw axis of the ground working machine. The plane preferably runs parallel to the roll axis and parallel to the yaw axis. However, the virtual pivot axis can be tilted about a reference axis orthogonal to the yaw axis and can approach the supporting ground of the ground working machine along the roll axis.

[0033] Starting from the closed position, the upper and lower covers can preferably be pivoted by more than 90° in order to ensure ergonomic accessibility to an operating panel of an operating module arranged at one of the two covers. Preferably, the two covers can be pivoted relative to each other by at least 160°, particularly preferably by at least 175°, even more preferably by between 178° and 182°.

[0034] In the above-mentioned embodiment according to which the cover bottom and the cover edge or the operating panel and the operating module are tilted relative to each other around the tilt axis, the tilt axis and the pivot axis preferably enclose an angle of 75° to 105°, particularly preferably an angle of 85° to 95°, and even more preferably a right angle.

[0035] The lower cover can be connected to a support member in a releasable manner as desired, which supports the lower cover when the ground processing machine is ready for operation. To this end, a locking mechanism can be formed at the support member and a locking mating mechanism can be formed at the lower cover, which can form a releasable form-fitting engagement. For example, one of the mentioned mechanisms can have a movable pawl, which engages in a recess of the corresponding other mechanism when the releasable form-fitting engagement is established and can be removed from the recess to disengage the form-fitting engagement. Then, if desired, the housing and the operating device can be removed from the rest of the ground processing machine and stored in a safe place during periods of inactivity of the machine.

[0036] The lower cover is preferably permanently connected to the support component, for example by screwing and / or riveting and / or gluing. Although the screw connection can also be disconnected as desired, the effort required for disconnecting the screw connection is chosen to be high enough due to the need for a tool and the duration of the tool intervention to disconnect the screw connection, so that the screw connection is only disconnected within the scope of repairs of the ground processing machine.

[0037] Compared to a permanent connection of the lower cowl to the bracket element, the above-mentioned expected detachability preferably involves a tool-free detachability or, if a tool is required, a tool intervention of less than 15 seconds to detach the bracket element of the lower cowl.

[0038] The support member carrying the lower cover or housing is connected to the machine frame. The support member can in principle be firmly and rigidly connected to the machine frame. In order to further adapt the operating workspace of the ground processing machine to the individual needs of the machine operator according to the corresponding operating situation, the support member can be movably connected to the machine frame relative to the machine frame. The relative movability of the support member (for example a tray) relative to the machine frame can be translational, so that the machine operator can move the operating module towards himself or away from himself and / or so that the machine operator can move the operating module close to or away from the side edge of the ground processing machine. Alternatively or additionally, the support member can be rotationally movable relative to the machine frame, so that the machine operator can place the operating panel in an orientation that is respectively advantageous to him.

[0039] In order to avoid undesired noise or mechanical loads, the upper cover can be connected to the base, for example to the above-mentioned support element, in the open position in a releasable manner as desired, in particular releasably. For example, the upper cover can be connected to the support element in a lockable and / or magnetic manner. In a particularly simple embodiment of the invention, the upper cover can be loosely arranged on the base in the open position.

[0040] In order to supply energy to the operating module and / or to transmit signals between the operating module and a data processing device of the control device arranged on the rest of the ground processing machine outside the operating device, at least one of the upper and lower covers can have an opening through which, in the operationally ready state, an electrical connection cable is led to the operating module. If the operating module is to be connected directly to an energy source or to a data processing device of the control device when arranged in either cover, an opening can be provided in each cover. If the operating module arranged in each of the other covers is to be connected to an energy source or a data processing device through an opening in this cover, an opening in only one of the covers is sufficient.

[0041] Establishing the connection between the operating module housed in the housing and the data processing device of the energy source and / or control device can be simplified in the following manner: at least one of the upper and lower housings has an external electrical connection port on its outer side, the external electrical connection port is used to be electrically connected to at least one onboard cable of the ground processing machine, and has an internal electrical connection port on its inner side that is electrically connected to the external electrical connection port, the internal electrical connection port is used to be electrically connected to the operating module. When the housing is arranged on the base of the ground processing machine, for example, on the above-mentioned support member, the external electrical connection port can be connected to the energy source and / or data processing device via at least one onboard cable. The operating module arranged in the housing having the internal electrical connection port can be electrically connected to the internal electrical connection port.

[0042] Because the lower cover is preferably always connected to the base regardless of whether the housing is in the open position or the closed position, an external electrical connection port is preferably provided at the lower cover. Preferably, external electrical connection ports are provided at the lower cover and the upper cover, wherein when the housing is in the open position, the external electrical connection port of the upper cover is preferably always electrically connected to the above-mentioned onboard cable.

[0043] The operating module preferably has an electrical coupling formation for coupling with an electrical connection cable and / or a mating port for coupling with an internal electrical connection port.

[0044] If the operating device is connected to the support member shell detachably and connectably as expected, the external electrical connection port of the lower cover and / or the contact port on the support member side preferably include one or more electrical plugs or spring contacts, so that the electrical contact between the external electrical connection port and the contact port on the support member side can be established without tools. One of the external electrical connection port and the contact port on the support member side is preferably configured as a plug, and the corresponding other port is preferably configured as a socket. In the case where the external electrical connection port is arranged at the upper cover, the description of the connection port of the lower cover applies accordingly to the external electrical connection port.

[0045] The same applies to the aforementioned direct connection of the operating module to the onboard electrical connection cable: the connection between the onboard electrical connection cable and the coupling component can preferably be established and secured without tools. For this purpose, one of the two components of the onboard electrical connection cable and the coupling component can be or have a plug, and the other component can be or have a socket, wherein the plug and the socket can preferably be secured to each other in a form-fitting manner without tools, for example, by a coupling sleeve with a thread or a bayonet component to prevent unintentional detachment.

[0046] In order to secure the operating module to a cover selected for accommodating it, according to a preferred improved form, it can be proposed that each of the upper cover and the lower cover has a placement component, and the operating element has a placement matching component, wherein the placement component and the placement matching component can be placed in a shape-fitting engagement that can be disengaged as expected to secure the operating module to one of the covers of the upper cover and the lower cover.

[0047] In a simple case, the mounting component and the mounting fitting component can be formed into Velcro by arranging a fiber ring entanglement as a mounting component on one of the operating module and the cover and arranging an elastic hook device as a mounting fitting component on the other component.

[0048] One of the placement components and the placement matching components can have a protrusion, which is engaged in a recess as a corresponding other component of the placement component and the placement matching component for form-fitting engagement. The protrusion can be configured as a clamp placed at both ends or as a protruding protrusion. At least one of the placement components and the placement matching components can be transferred between a form-fitting engagement position and a release position so that the form-fitting engagement established once can be disengaged as expected. The transfer between the form-fitting engagement position and the release position can only be carried out by exerting force. In order to prevent unauthorized extraction of the operating module from the cover, the transfer can use a closing secret, for example, by a key, an alphanumeric code, a fingerprint, data, etc.

[0049] The mounting components and the mounting engagement components are preferably arranged asymmetrically on their respective components, namely the cover and the operating module, so that the operating module can only be inserted into the respective cover in a relative position relative to the upper cover or the lower cover and can be secured there by a releasable form-fitting engagement.

[0050] In order to simplify the debugging of the floor processing machine and in particular the operating device, it can be proposed that at least one of the upper cover and the lower cover and the operating module are coordinated with each other so that when a releasable shape-fitting engagement is established between the mounting components of the corresponding cover and the mounting mating components of the operating module, an electrically conductive connection is automatically established between the internal electrical connection port of the corresponding cover and the mating port of the operating module.

[0051] The complementary design already described above of the inner side of the cover and the outer side of the operating module, which is opposite the inner side of the cover in the operationally ready state, can facilitate this coordination.

[0052] The coordination for automatically establishing the conductive connection between the internal electrical connection port and the mating port can also be caused at least in part by a movement sequence preset by the placement component and the placement matching component of the relative movement of the operating module and the cover when the operating module is arranged in the cover selected for the arrangement. This sequence can be achieved by the corresponding physical and / or kinematic configuration scheme of the placement component and the placement matching component. In addition to the above-mentioned elements, namely the protrusions and recesses, at least one of which can be transferred between a form-fitting engagement position and a release position to disengage the form-fitting engagement established between them according to the expectation, the placement component and the placement matching component can have a combination of fixed, form-fitting elements, namely protrusions and recesses, formed at the cover and the operating module, which are immovable relative to the structures in the operating module and the cover that carry them respectively. Thus, the movement process can be determined so that the combination of fixed form-fitting elements must form a form-fitting engagement with each other at the two components, and then the form-fitting engagement only runs a certain degree of freedom of movement in order to place the combination of releasable form-fitting elements in a form-fitting engagement that can be disengaged according to the expectation. For example, a combination of fixed form-fitting elements can include at least two protruding projections arranged at a distance from one another on one component and two recesses or depressions arranged at the same distance from one another on the respective other component.

[0053] In principle, the operating module can have a data processing device which is designed to process signals from sensors at the ground working machine and from control inputs at the control elements and to output control commands to actuators at the ground working machine.

[0054] The control device of the ground processing machine preferably also has at least one data processing device, which is arranged outside the operating module and carried by the machine frame, and to which the operating module can be connected for signal transmission. The operating module is then increasingly used as an input module for inputting data and control commands. This reduces the costs of the operating module and simplifies the replacement of the operating module at the ground processing machine to adapt to changing processing tasks or new ergonomic findings.

[0055] The data processing device, whether arranged in the rest of the ground working machine in the operating module and / or outside the operating module, comprises at least one processor, for example a microprocessor, and at least one memory in which at least one program executable by the processor is stored, the program being used to control the functional components of the ground working machine. The data processing device comprises at least one memory for storing data, i.e., for example, sensor data, data generated by actuation of one or more operating elements of the operating panel, data for executing at least one program. The ground working machine can have at least one or more sensors, which are connected to the data processing device in terms of signal transmission, and which detect the operating conditions of the ground working machine, i.e., for example, its travel speed, the position and state of the actuators, the steering angle of the running gear components, the spatial arrangement and / or orientation of the components of the ground working device, any movement speed and / or movement direction of the components of the ground working device, etc.

[0056] In order to provide the machine operator with feedback on the operating status, the operating module preferably comprises at least one output device for outputting signals and / or data. Such an output device may comprise a monitor, in particular a touch screen which can also be used as an input device, a loudspeaker, a signal lamp, a tactile output device, i.e., for example, a vibrator, etc. Thus, the operating module can output data from the data processing device to the machine operator independently of its arrangement location.

[0057] The housing has at least two covers, namely an upper cover and a lower cover. Thus, the housing can permanently accommodate at least two operating modules at the same time. Thus, on the one hand, the modules can be arranged in one cover or in the other cover. In order to expand the range of functions, the operating module can be a first operating module, wherein the control device also has a second operating module in addition to the first operating module. Each of the first operating module and the second operating module can then be preferably arranged in each of the upper cover and the lower cover in a ready-to-operate manner and also in fact in a ready-to-operate state of the ground processing machine.

[0058] The above description of the operating module or the first operating module is also applicable to the second operating module. In particular, the electrical coupling components of the first operating module and the second operating module are constructed identically. Since the internal electrical ports of the upper cover and the lower cover are also constructed identically, the positioning of the first operating module and the second operating module in the lower cover or the upper cover can be freely selected. The operating panel of the second operating module is preferably different from the operating panel of the first operating module in terms of the type of operating elements arranged there and / or the arrangement of the operating elements and / or the functional allocation of the operating elements, so as to provide different functions for the machine operator at the two operating modules and to enable the machine operator to know at a glance: which of the two operating modules he is currently working at.

[0059] In principle, it is sufficient for the housing to have exactly one upper cover and one lower cover. However, a larger space in which at least one operating module can be locally installed can be provided at the ground processing machine in that the housing has a second upper cover in addition to the upper cover and / or has a second lower cover in addition to the lower cover. The housing preferably has more upper covers than lower covers, since the lower covers are preferably firmly connected to the base at least during operation of the ground processing machine. Therefore, an embodiment with one lower cover and two upper covers is particularly preferred. The upper covers are preferably designed with the same upper cover volume, particularly preferably as identical parts or as components designed in a mirror-symmetrical manner.

[0060] If the housing has a second upper cover in addition to the upper cover, the second upper cover and the lower cover are preferably pivotable relative to each other about a second virtual pivot axis. Each virtual pivot axis for pivoting the upper cover relative to the lower cover is preferably realized at a straight edge of the lower cover and the upper cover. In order to be able to arrange at least one operating module at a cover in the largest possible area on the ground processing machine, when two upper covers are arranged, the virtual pivot axis and the second virtual pivot axis are preferably formed at opposite edges of the lower cover.

[0061] If the second virtual pivot axis forms a certain angle with the first virtual pivot axis, the two upper and lower covers can ergonomically advantageously surround the workspace of the machine operator at the floor processing machine in a curved direction. However, the angle is preferably not greater than 30°. Thus, in the open state of the housing, the sequence from one end region of the housing to the other end region of the housing via the two virtual pivot axes is: upper cover - lower cover - second upper cover.

[0062] In the case of ground processing machines of particular interest at present, i.e., for example, slipform pavers, the operating station usually extends in a straight line in the machine transverse direction. Therefore, the second pivot axis is particularly preferably oriented parallel to the first pivot axis. The housing is preferably designed mirror-symmetrically with respect to the symmetry plane. Here, the symmetry plane is orthogonal to the bottom of the lower cover as an angle bisector or as a parallel line of two virtual pivot axes, which define the two upper covers and the common lower cover.

[0063] The invention can be used particularly advantageously on slipform pavers. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] exist Figure 1 Schematically shown is an embodiment of a ground processing machine 10 (hereinafter also referred to as "machine 10") in the shape of a slipform paver according to the present invention. The machine 10 includes a machine frame 12, which is supported by a traveling mechanism 14. The traveling mechanism 14 has a plurality of traveling mechanisms, which can roll on the supporting ground. In the example shown, the traveling mechanism is a chain traveling mechanism with a circulating chain. At least one of the traveling mechanisms or all of the traveling mechanisms can be roller or wheel traveling mechanisms. In the example shown, the traveling mechanism 14 has two front traveling mechanisms 16 and one rear traveling mechanism 18. Instead of this configuration, two rear traveling mechanisms can also be provided. The rear traveling mechanism 18 can be positioned along the traveling mechanism support 20 toward the machine transverse direction Q or along the pitch axis Ni opposite to the machine transverse direction by a corresponding servo motor.

[0075] Each of the traveling mechanisms 16 and 18 has a hydraulic motor 22 as a travel drive 24 in a known manner. An internal combustion engine 26, more precisely a diesel internal combustion engine 26, serves as the power mechanism of the machine 10 and provides the energy required for the operation of the machine 10. The required energy is extracted from the rotating crankshaft of the internal combustion engine 26 in order to provide hydraulic energy for hydraulic actuators and loads, such as hydraulic motors and piston-cylinder assemblies, in addition to the kinetic energy of the crankshaft via a hydraulic pump, to provide electrical energy for electrical loads and chargeable electrical energy storage devices via a generator, and optionally to provide pneumatic pressure for pneumatic actuators and loads via a pneumatic compressor.

[0076] The distance between the machine frame 10 and the support surface of the machine 10 along a yaw axis Gi running parallel to the height direction H of the machine can be set individually for each chassis via the lifting columns 14 a of the chassis 14 .

[0077] On the machine frame 12, only exemplarily, Figure 1 A known sliding formwork 28 is arranged at the left machine edge, which is used to form a concrete molded body as a floor processing device. The sliding formwork 28 is supplied with flowable concrete via a hopper 30. The hopper 30 is supplied with flowable concrete via a conveyor belt 32, which conveys the flowable concrete from a receiving silo 34 at the front region of the machine 10 to the hopper 30.

[0078] The sliding formwork 28 forms a mold cavity together with the support surface of the machine 10, in which the flowable concrete flowing into the cavity from the funnel 30 is formed in a known manner as a positive image of a formwork wall which surrounds the mold cavity in a circumferential direction about a rolling axis Ro extending parallel to the machine longitudinal direction L and serves as a negative mold. The flowable concrete is fixed at the latest at the outlet 28a of the sliding formwork 28 relative to the support surface that contributes to its formation and flows out through the outlet 28a at the rear end of the sliding formwork 28 during operation of the machine 10 in a coordinate system that is fixed relative to the sliding formwork at a speed whose value corresponds to the travel speed of the machine 10 and the feed speed, but in the opposite direction. The feed speed of the machine 10 and the concrete mixture applied by the sliding formwork 28 are coordinated with each other so that the concrete solidifies in a dimensionally stable manner between its entry into the sliding formwork and its outflow from the sliding formwork 28, so that the concrete retains the shape it has acquired after it has flowed out of the sliding formwork 28.

[0079] The machine 10 has a cab 38 which is accessible from the supporting ground via a staircase 36 and which extends along the pitch axis Ni substantially over the entire machine width of the machine 10. Figure 1The machine operator working in the cab 38 spends most of his working time in the cab 38 observing the concrete molded body flowing out of the sliding formwork 28. Therefore, the machine operator mainly stays in the end area of ​​the cab 38 closest to the sliding formwork 28.

[0080] A control device 40 is arranged on the driver's cab 38 for controlling the machine 10 , the control device comprising two housings 42 and 44 and two operating modules 46 and 48 .

[0081] The two housings 42 and 44 are arranged side by side along the pitch axis Ni and are mirror-imaged about a symmetry plane orthogonal to the pitch axis Ni. Taking into account the mirror symmetry, the following description of the housing 42 is sufficient, and its description also applies to the housing 44 taking into account the symmetry conditions.

[0082] Figure 1 Each of the housings 42 and 44 has a lower cover 52 fixedly connected to a console 50 as a support member and an upper cover 54 pivotable relative to the lower cover 52 about a pivot axis P. Due to the mirror-symmetrical construction of the housings 42 and 44, in the open state of the housings, the lower covers 52 of the housings are directly adjacent to each other along the pitch axis Ni and are located between their upper covers 54.

[0083] exist Figure 1 4 shows the respective open state of the two housings 42 and 44. The operating modules 46 and 48 are located here only in the housing 42, specifically the operating module 46 in the lower cover 52 of the housing 42 and the operating module 48 in the upper cover 54.

[0084] exist Figure 2 3 shows the individual states of the cab 38 and its raised part 36, wherein the housings 42 and 44 are still in their respective open states. Figure 3 China-Israel Figure 2 The same perspective view shows the cab 38 and its riser 36 , but with the housings 42 and 44 in a closed state.

[0085] exist Figure 2 and Figure 3 The frame 56 is shown as part of the cab floor 58. Figure 1 The machine operator is located on the cab floor 58 during its operation to control the normal operation of the ground processing machine 10.

[0086] The upper cover 54 and the lower cover 52 can be rotated relative to each other about the pivot axis P. Figure 3 The closed position shown in Figure 2The housing 42 is pivoted by about 180° relative to one another between the open positions shown in FIG. 4 and FIG. 4 . For greater clarity, the pivot axis P is shown only at the hinge 60 connecting the upper cover 54 to the lower cover 52 of the housing 42. The pivot axis P lies in a plane extending parallel to a plane extending through the yaw axis Gi and the roll axis Ro. However, in the preferred embodiment shown, the pivot axis P is neither parallel to the roll axis Ro nor to the yaw axis Gi.

[0087] Figure 2 The housing 44 not occupied by the operating module shows the concave inner side 52a of the lower cover 52 in each of two mutually orthogonal spatial directions and the concave inner side 54a of the upper cover 54 in each of two mutually orthogonal spatial directions. Possible designs of the lower cover 52 and the upper cover 54, which are also applicable to the housing 42, are shown in Figure 2 It is shown at housing 44.

[0088] Figure 2 The operating module 48 in the machine 10 can be connected to the operating module 46 via a connecting cable 62 for signal and energy transmission. The operating module 46 is the only operating module at this time, which is connected to the onboard energy source of the machine 10 and, if necessary, to the data processing device 64 of the machine 10. The data processing device 64 can be arranged in the control console 50 of the cab 38 of the machine 10 or at another suitable location.

[0089] The connection of the transmission signal and energy of the operating module to the on-board components of the machine 10 can be realized in the form of a cable connection. For this purpose, a hole 66 that penetrates the lower cover 52 can be constructed in the cover of the housing 44, for example, in the lower cover 52 as a cable feedthrough. Additionally or additionally, an internal electrical connection port 68 can be constructed on the concave inner side 52a of the lower cover 52, especially on the inner side of the cover bottom 52b, which automatically establishes an electrical connection between the transmission signal and energy of the operating module and the on-board components of the machine 10 when the operating module is arranged in the lower cover 52. The cover bottom of the upper cover 54 is correspondingly represented by 54b. As described below, the internal electrical connection port 68 is also an internal mechanical connection port.

[0090] The internal electrical connection port 68, which is only schematically shown, can have a physical structure 68a protruding away from the bottom 52b of the housing. The operating module can have a corresponding complementary recess on its operating module bottom as part of the mating port on the operating module side. When the operating module is arranged in the lower cover 52 or the upper cover 54, the physical protrusion 68a of the internal electrical connection port 68 extends into the recess of the mating port on the operating module side, wherein the lower shell or the upper shell can have the same internal electrical connection port 68 to ensure the arrangeability of the operating module in the two shells 52 and 54. Obviously, the distribution of protrusions and recesses can be selected differently from the illustrated embodiment. In order to ensure that the operating module 46 or 48 can be arranged on a seat of another plane different from the bottom of the cover of the lower cover 52 or the upper cover 54 without tipping over or shaking, it is preferred that the physical structure 68a is formed in the internal electrical connection port of the cover 52 and 54 and the recess corresponding to the structure and accommodating the physical structure is formed in the mating port of the operating module 46 and 48.

[0091] The internal electrical connection port 68 has a contact device 68b, such as a spring contact piece, which contacts the mating contact device on the operating module side when the internal electrical connection port 68 is connected to the mating port of the operating module because the connection port 68 and the mating port are complementary.

[0092] The spring-loaded locking latch 68c can engage in a corresponding locking recess in the mating port of the operating module and thereby secure the operating module to the corresponding cover in a form-fitting manner. The spring-loaded locking latch 68c is part of the placement component 70, and the locking recess is part of the placement mating component on the operating module side. The locking latch 68c can be retracted into the physical structure 68a of the internal electrical connection port 68 by an actuator (not shown in the figure) in order to disconnect the once-established physical connection between the corresponding cover and the operating module again. The actuator can be operated in a motor-driven manner or manually, for example by a connecting rod.

[0093] exist Figure 3 4 shows the housings 42 and 44 in a closed position in which they completely surround the operating module accommodated therein or the interior space surrounded by the concave inner sides 52 a and 54 a.

[0094] exist Figure 3 The upper cover 54 of the housing 42 may have a hole 66 as a cable feed-through portion so as to be connected to the upper cover 54 of the housing 42. Figure 2The onboard connection cable 72 guided through the console 50 is connected to the operating module 48 accommodated in the upper cover 54 in a signal and energy transmission manner through the hole 66. The plug 72a at the free longitudinal end of the onboard connection cable 72 forms a first onboard port for connecting the operating module 46 or 48 to the onboard energy supply device of the machine 10 and / or to the onboard data processing device 64.

[0095] exist Figure 3 An external electrical connection port 74 is shown on the outside of the operating module bottom 54b of the upper cover 54 of the housing 44 in the figure, which has a recess or recess 74a on the outside of the operating module bottom in the operating module bottom 54b. The external electrical connection port 74 is in principle constructed like the above-described mating port of the operating module, because the external electrical connection port 74 is constructed in the same way as the mating port of the operating module for mechanical and electrical coupling with the internal electrical connection port 68 for mechanical and electrical coupling with two onboard ports 76 on the base 50a of the operating console 50 used as a support member and covered in the open state of the housing 44.

[0096] The external electrical connection port 74 on the outside of the operating module bottom 54b is configured to be smaller than the internal electrical connection port 68 on the inside of the operating module bottom 54b and is completely covered by the larger internal electrical connection port 68 when viewed orthogonally to the operating module bottom 54b, wherein the external electrical connection port is also an external mechanical connection port like the previously described internal electrical connection port 68. The electrical mating contact device 74b at the external connection port 74 is used to make electrical contact through the contact device 76b at the physical structure 76a of the second onboard port 76. Figure 3 The spring-preloaded locking latch 76 c in the extended position shown in FIG. 4 serves to temporarily secure the upper cover 54 above the base 50 a in the open position of the housing 44 in a form-fitting manner.

[0097] The contacts of the mating contact device 74b are directly connected with the contacts of the contact device 68b on the inner side of the upper cover 54. Therefore, when the upper cover 54 is in the intended locking engagement with the second onboard port 76 via its external electrical connection port 74, the operating module arranged on the recessed inner side 54a of the upper cover 54 is electrically connected with the onboard energy supply device of the machine 10 and the onboard data processing device 64 via its contact device in its mating port, the contact device 68b of the internal electrical connection port 68 of the upper cover 54, the mating contact device 74b of the external electrical connection port 74 of the upper cover 54, and the mating contact device 76b of the second onboard port.

[0098] Apart from being smaller in size, the second onboard port 76 is constructed like the internal electrical connection port 68, so that its description can also be applied to the second onboard port 76, wherein only the numeral 68 is replaced by the numeral 76. The physical structure 76a is constructed complementary to the recess 74a of the external electrical connection port 74 and projects into the recess 74a of the upper cover 54 in the open position of the housing 44.

[0099] In the embodiment, the upper cover 54 of the housing 42 equipped with the operating modules 46 and 48 only lies flat on the support buffer 78 at the operating console 50 in an unlocked manner in the open position. The different views of the design of the housings 42 and 44 in the embodiment are only used to provide information about the basic possible design forms. Generally, the housings 42 and 44 are constructed identically within the scope of the above-mentioned mirror design.

[0100] exist Figure 4 , the housing 42 and the operating modules 46 and 48 accommodated therein are shown separately. The operating modules 46 and 48 respectively have display devices 46a and 48a for displaying data and for outputting information. The display devices 46a and 48a are constructed differently and are used for different visual information outputs during operation. In addition, each operating module 46 and 48 respectively has its own operating panel 46b or 48b, which has operating elements arranged separately thereon, see, for example, operating elements such as toggle switches 49a, pressure switches 49b and rotary switches 49c. The operating panels 46b and 48b have the same total area. The operating elements of the two operating panels 46b and 48b differ in their arrangement on the operating panels and in their functions and operation types. Although the main toggle switches 49a and only a few rotary switches 49c and pressure switches 49b are arranged on the operating panel 46b, the main rotary switches and pressure switches 49c or 49b are arranged on the operating panel 48b.

[0101] In principle, the operating panels 46b and 48b can be configured to operate different machine functions. For example, concrete equipment, including but not limited to material conveying devices, tank control devices, vibrators, etc., can be controlled by means of one of the operating modules 46 or 48, and mechanical kinematic components, including but not limited to travel drive 24, height adjustment devices by means of lifting columns 14a, steering positioning devices of transmission devices 16 and 18, can be controlled by means of the respective other operating module 48 or 46. There can also be functions that can be controlled at each of the operating modules 46 and 48.

[0102] The operating panels 46b and 48b on which the operating elements are mounted are substantially planar and, in the example shown, are aligned parallel to the bottom 46c and 48c of the operating module 46 or 48 (see also Figure 8 ).

[0103] The upper cover 52 and the lower cover 54 are delimited by cover edges 52c and 54c, respectively, which are flat against each other in the closed position of the housing. The cover edges 52c and 54c are respectively planar cover edges, i.e. they are respectively located in one plane. The cover edges 52c and 54c are preferably coplanar in the open position of their housings 42 and / or 46, e.g. Figure 4 and Figure 7 The situation in.

[0104] As in Figure 4 and 7 It can be seen that the planes of the hood edges 52c and 54c are tilted relative to the planes of the associated hood bases 52b and 54b about the tilt axis N. In the state in which the housings 42 and 44 are arranged in an operationally ready state on the operating table 38, the tilt axis N preferably extends parallel to the pitch axis Ni on the side of the housings 42 and 44 on which the workspace W of the machine operator is located (see Figure 2 and 3 ).exist Figure 4 and Figure 7 In the view of FIG. 4 , the tilt axis N is shown closer to the housing 42 than is actually the case. Figure 3 A more realistic position of the tilt axis N relative to the housings 42 and 44 is shown.

[0105] Thus, the side walls 52d and 54d of the lower or upper hood 52 or 54, which are arranged farther from the machine operator and extend along the pitch axis Ni, extend further upward from the corresponding hood bottom 52b or 54b than the side walls 52e and 54e, which also extend along the pitch axis Ni and are closer to the machine operator. Thus, the side walls 52d and 54d arranged farther from the machine operator extend further than the side walls 52e and 54e arranged closer to the machine operator over the operating panels 46b and 48b of the operating modules 46 or 48 accommodated in the corresponding hoods 52 and 54. Thus, a certain level of glare protection can be achieved for the operating panels 46b and 48b with respect to the light sources arranged in front of the machine 10. In addition, the housing 42 can thus be closed without the operating elements protruding from the corresponding operating panels 46a and 48a colliding with each other or with the operating panels of the corresponding other operating module.

[0106] Figure 5 Shown with Figure 4 The same arrangement, but shown from the front diagonally. Figure 5In the figure, on the outer side of the side walls 52d and 54d, a damper 80 is shown which connects the two covers 52 and 54 to each other at their hinge points 81a and 81b, and which limits the pivoting speed of the pivoting movement of the covers 52 and 54 relative to each other, so as to prevent: the upper cover 54 equipped with the operating module 48 from hitting the support buffer 78 at high speed and being extremely decelerated there under the action of high forces. As a result, the electronic device in the operating module 48 can be protected from undesirable damage caused by impact when the housing 42 is opened. The damper 80 can be a fluid damper known per se, such as an overflow damper, which limits the relative speed between the cylinder 80a and the piston rod 80b extending therefrom by allowing a viscous liquid to flow through an opening in the piston accommodated in the interior of its cylinder 80a. Therefore, the flow resistance increases approximately in the square of the flow speed at the flow obstacle, so that the braking effect applied by the damper 80 to the housing covers 52 and 54 gradually increases as the relative pivoting speed of the two housing covers 52 and 54 increases.

[0107] Side walls 52f and 52g of the lower cover 52 that are opposite to each other along the pitch axis Ni and side walls 54f and 54g of the upper cover 54 that are opposite to each other along the pitch axis Ni connect the side walls 52d and 52e or the side walls 54d and 54e to each other. The side walls marked with "f" are directly connected by hinges 60. In the closed position of the housing 42, the side walls of the upper and lower covers marked with the same lowercase letters are connected to each other on their corresponding side edges marked with lowercase letters "c".

[0108] exist Figure 6 The semi-open position between the open and closed positions is shown in FIG. Figure 5 The housing 42 is provided.

[0109] exist Figure 7 In the figure, the operating modules 46 and 48 are shown without the housing 42. The operating modules 46 and 48 have substantially the same outer shape and substantially the same ports, which is why it is sufficient to describe only one of the operating modules 46 and 48 at present, because their description also applies to each other operating module except for the corresponding different operating panels 46b and 48b.

[0110] The operating module 46 has an edge 46d, from which the outer wall of the operating module 46, see for example the outer walls 46e and 46h, extend toward the bottom 46c of the operating module 46. The outer wall of the operating module 46 surrounds the electrical components arranged below the operating panel 46a. The electrical components are directly connected to the operating panel 46a. In the illustrated embodiment, the edge 46d is at the same height as the operating panel 46b at the area of ​​the operating module 46 that is arranged closer to the machine operator during operation. At the area of ​​the operating module 46 that is arranged farther away from the machine operator during operation, the edge 46d extends beyond the operating panel 46b at a distance from the operating panel 46b, so that the outer wall 46e of the operating module 46 that points away from the machine operator during operation along the rolling axis Ro can be formed with handle recesses 46f and 46g, which simplify the insertion of the operating module 46 into one of the covers 52 and 54 and simplify the removal of the operating module 46 from the corresponding cover.

[0111] The outer shape of the operating module 46 tapers from the edge 46d to the bottom 46c, so that the outer shape of the operating module 46 has a generally convex shape, which fits into the concave inner side 52a and 54a of the housing 52 or 54. In order to provide the convex shape, the lateral outer wall 46h has, for example, a curved section 46h1, which is curved around the curvature axis KM. Due to the convex shape of the operating module 46, the area of ​​the bottom 46c of the operating module 46 is smaller than the area of ​​the operating panel 46b.

[0112] The lateral outer wall sections 46h2 and 46h3 below and above the curved section 46h1 are substantially planar and are inclined relative to one another about the axis of curvature KM due to the curved section 46h1 located therebetween.

[0113] The locking mechanism 82 with the locking pawl device 82a is arranged on the outer wall 46e as part of the mounting fitting component 71. By means of a button 82b, the locking pawl device 82a can be placed in a release position in which the locking pawl device releases the mounting fitting component 70. Figure 8 84 shown in FIG. The locking pawl device 82a is adjusted, for example, by an over-dead-center kinematic device so that it is transferred by the locking pin 84 into a positive-fitting engagement position around the locking pin 84 when the locking pin 84 is introduced into the locking pawl device 82a and remains there until the button 82b is actuated. Alternatively or in addition to the above-mentioned connection port 68, the operating module 46 can be mechanically and securely arranged in one of the lower cover 52 and the upper cover 54 by means of a locking mechanism 82 and a locking pin 84 by means of a positive-fitting engagement.

[0114] The locking pin 84 protrudes, for example, from each side wall 52d and 54d toward the respectively opposite side wall 52e and 54e. Due to this asymmetrical arrangement, the operating module can only be arranged in one of the covers 52 and 54 in exactly one relative position.

[0115] The side walls of the housing shells 52 and 54 are also inclined to provide a concave interior and enclose an angle greater than 90° with the bottom 52b or 54b.

[0116] Figure 8 and Fig. 9 Bending axes KS1 to KS6 are shown, about which adjacent sections of the side wall of the upper cover 54 arranged on both sides of the corresponding bending axis are bent relative to each other. Bending axes KS1, KS2, KS5 and KS6 extending along the side walls 54f and 54g are bent relative to Fig. 9 The perpendicular median plane MSE orthogonal to the drawing plane is formed on the cover bottom 54b in a mirror-symmetrical manner and is inclined relative to each other. However, this is only one embodiment. On the other hand, the bending axes KSM3 and KSM4 belonging to the side wall 54e are parallel to each other and parallel to the pitch axis Ni in the operationally ready state. The side wall segments 54e1, 54f1 and 54g1 arranged closer to the cover bottom 54b are less curved relative to the cover bottom 54b than the side wall segments 54e2, 54f2 and 54g2 of the same side walls 54e, 54f and 54g arranged farther away.

[0117] The side walls 52e, 52f and 52g of the lower cover 52 are configured differently from the corresponding side walls of the upper cover 54 in the area near the cover bottom 52b of the lower cover 52. However, the side walls 52e, 52f and 52g have the same inclination angle with respect to the cover bottom 52b of the lower cover 52 as the side edge sections 54e1, 54f1 and 54g1 of the corresponding side walls of the upper cover 54. The corresponding contents apply to Figure 8 and Fig. 9 This ensures that sections of the outer wall of the operating module 46 or 48 rest against the inner sections of the side walls 52d, 52e, 52f and 52g and 54d, 54e, 54f and 54g with little play or preferably without play.

[0118] like Figure 7 As shown, the operating modules 46 and 48 have a coupling component 86 in addition to or instead of the mating port coupled to the internal electrical connection port 68, which can be coupled to the plug 72a of the onboard cable 72 to supply power to the coupled operating module and to ensure signal transmission with the onboard data processing device 64. The coupling component 86 is configured for quick connection with the plug 72a at the onboard connection cable 72. The plug 72a can be secured at the coupling component 86 in a form-fitting manner by a bayonet lock or a union nut.

[0119] In addition, the operation module has a forwarding port 88, such as Figure 2 As shown, via the forwarding port, another operating module can be connected to the operating module directly connected to the onboard connecting cable 72 via the connecting cable 62 to supply power and transmit signals. The connecting cable 62 can be connected to the forwarding port 88 of this operating module at one end and to the coupling component 86 of the other operating module at the other end. The forwarding port 88 is also a quick connection port, which has, for example, a bayonet- or union nut-secured device for establishing an electrical connection once.
