Description

Field of the Invention

[0001] The present invention relates to a self - propelled surface processing machine, comprising a machine frame, a traveling mechanism for carrying the machine frame, a traveling drive, and a surface processing device configured for processing the surface. The surface processing machine has a control device for controlling the operation of the surface processing machine. The control device has an operation module, and the operation module has a plurality of operable elements that can be selectively actuated. The actuation of the operable elements is adapted to change the operation state of the surface processing machine. The control device has at least a two - piece housing in which the operation module is accommodated. The housing has a lower cover and an upper cover, and the lower cover and the upper cover can move relative to each other between a closed position and an open position. The operable elements of the operation module accommodated in the housing can be accessed in the open position of the housing. The housing and at least one operation module together form an operation device. Background Art

[0002] Compared with the closed position of the housing, the operable elements can be accessed to a greater extent in the open position of the housing. This can be achieved in such a way that the operable elements are more accessible in the open position of the housing than in its closed position and / or the operable elements can be accessed with less access effort in the open position of the housing compared with its closed position. Preferably, most of the operable elements, particularly preferably all operable elements, are inaccessible in the closed position of the housing.

[0003] Such a surface processing machine is known, for example, from EP 3 524 461 A1. Among them, road milling machines, recycling machines, and open - pit mining machines are exemplarily listed as possible surface processing machines. In the closed position, the upper cover and the lower cover completely hide the operation module accommodated in the housing to protect it from vandalism. This kind of vandalism sometimes occurs when the surface processing machine is parked overnight at a construction site and a person with malicious intent enters the construction site.

[0004] In the known operation device composed of the housing and the operation module, the operation 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 disengaged from the lower cover of the known operation device, lifted, and can be retracted away from the lower cover during the operation duration of the surface processing machine. The known upper cover has a substantially planar plate shape with some minor stiffening ribs.

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

[0006] A wireless operating device for a vehicle component is known from US2015 / 0321597 A1. Its portable housing has a lower cover and an upper cover, and a removable operating module arranged therein in the desired case. 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 waist of a machine operator via a separate bracket or arranged in the cab of a vehicle.

[0007] Operating units for controlling irrigation equipment are known from US 7,953,517 B1 and US10,069,284B1 respectively. Each operating unit is accommodated in a plastic housing having a lower cover and an upper cover pivotally fixed to the lower cover. The operating device itself is pivotally connected to the housing relative to the housing. The pivot axis of the housing and the pivot axis of the operating device are parallel or collinear with each other. Summary of the Invention

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

[0009] The self-propelled ground working machine according to the present invention includes a machine frame, a traveling mechanism carrying the machine frame, a traveling drive, and a ground working device configured to work on the ground. The ground working machine has a control device for controlling the operation of the ground working machine. The control device has an operating module having a plurality of selectively actuable operating elements. Actuation of the operating elements is adapted to change the operating state of the ground working machine. The control device has at least a two-piece housing in which the operating module is accommodated. The housing has a lower cover and an upper cover, and the lower cover and the upper cover can move relative to each other between a closed position and an open position. The operating elements of the operating module accommodated in the housing can be accessed in the open position of the housing. The operating module can be separated from the housing and can be arranged at the housing. The operating module can be arranged at each of the upper cover and the lower cover in a ready-to-work manner.

[0010] Here, "in a ready-to-operate manner" means that, with the surface processing machine and the connected operation module in an operation-ready state, the mechanical operator controlling the surface processing machine can reach the operating elements as expected. At least a part of the operation module, preferably all operating elements, are connected to the data processing device of the control device in terms of signal transmission, such that their actuation causes a state change of the functional devices of the surface processing machine in a predictable manner. Thus, the actuation of the operating elements of the operation module can control different actuators of the surface processing machine, for example in order to move the surface processing machine by means of the travel drive and / or to change the direction of movement of the surface processing machine during movement by manipulating the running gear and / or in order to control the operation of the surface processing device, to name just a few examples.

[0011] Although the operation module can also and usually is accommodated in one of the two covers in a disconnected manner, the housing serves not only for transporting the operation module between the stowed location and the location of use. Instead, the housing serves for firmly anchoring the operation module in the work area of the mechanical operator of the surface processing machine in a ready-to-operate state and preferably also in a stationary state in which the surface processing machine is in a disconnected manner.

[0012] Depending on the type and scope of the surface processing of the surface processing machine, the operating device composed of the housing and the operation module can be arranged at different locations of the surface processing machine, where the surface processing machine can perform the surface processing due to the surface processing device arranged thereon. The surface processing machine preferably has an operation station at which the mechanical operator stays at least during the operation of the surface processing machine to control the surface processing machine. Thus, the operating device is preferably arranged at the operation console, particularly preferably within the reach of an adult around a possible operation seat provided and / or within the reach of an adult standing on the floor of the operation console.

[0013] The operation module is preferably arranged in one of the upper cover and the lower cover such that the operation module is physically connected to the cover and held at the cover.

[0014] The housing preferably has a housing volume in which the operation module is accommodated in the case of an intended arrangement in the cover, where the housing volume is surrounded by the housing in the closed position. Thus, the housing can protect the operation module from external access in the closed state. An exception to the closed enclosure of the housing volume by the housing can be formed by through openings which can be provided at the housing in order to enable connection cables for transmitting signals and / or energy between the components of the surface processing machine and the operation module.

[0015] By virtue of the basic arrangeability of the operating module in each of the upper hood and the lower hood, there are basically two different arrangement locations for arranging the operating module. Depending on the position where the machine operator stays during the ground processing or also during only one driving operation of the ground processing machine, he can arrange the operating module in the hood that is distributed closer to his staying location in the upper hood and the lower hood in a work-ready manner, and then stay at his staying location or leave the staying location only slightly and / or briefly in order to control the operation of the ground processing machine.

[0016] In order to protect the operating module without having to transfer the operating module after the end of the work shift and after switching off the ground processing machine, it is preferably provided that the operating module can be arranged at the respective inner side of the upper hood or the lower hood or at least during the operation of the ground processing machine. Then, regardless of whether the operating module is currently actually arranged in the upper hood or in the lower hood, by placing the housing in its closed position, the operating module can be retained in the housing to prevent unwanted access from the outside.

[0017] Preferably, the operating module can only be arranged at the inner side of the upper hood and the inner side of the lower hood respectively, or at the inner side of the hoods respectively selected for arrangement in the upper hood and the lower hood.

[0018] To avoid any doubt, it should be clear that the inner sides of the upper hood and the lower hood are those sides of the mentioned hoods that are opposite to each other and / or point to each other in the closed position of the housing.

[0019] In order to achieve that each of the upper hood and the lower hood that constitutes a hood for accommodating 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 have to be touched by the machine operator during operation, according to a preferred refinement of the invention, each of the upper hood and the lower hood has a concave inner side that is configured to accommodate the operating module. The inner sides of the upper hood and the lower hood are distributed to be configured to accommodate the operating module.

[0020] In order to more easily arrange the operating module in one of the upper hood and the lower hood in a manner that minimizes errors, preferably, the inner sides of the upper hood and the lower hood and the outer sides of the operating module that are opposite to the corresponding hood inner sides in the operation-ready state are complementarily configured. Thus, if the inner side of the hood tapers from the hood edge to the hood bottom, that is, the net area enclosed by the corresponding inner side of the hood shrinks when approaching the hood bottom from the hood edge, a favorable short equipment time of the operating device can be achieved by using the self-centering effect of the hood selected for arrangement of the operating module.

[0021] Here, the cover edge is the edge of the upper cover and the lower cover that bounds the opening of the respective cover facing radially outwards, 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 approaching direction so as to make it more difficult to pry the housing out of the closed position by tool intervention in the gap formed between the upper cover and the lower cover.

[0022] Preferably, the section of the outside of the operating module that is surrounded by the upper cover or the lower cover in the ready-to-operate state of the operating module tapers complementarily from the operating panel carrying the operating element to the bottom of the operating module at a certain distance from the operating panel. Preferably, in the ready-to-operate state of the operating module accommodated in the respective cover, at least the sections of the outside of the operating module and the inside of the operating simulation are in contact with each other. This can promote the above-mentioned preferred centering effect.

[0023] In principle, the cover edge can have any shape. Advantageous in terms of manufacturing technology while making good use of the structural space is that 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, and two of each of these edge sections extend parallel to each other in pairs. As is typical for a rectangular shape, different pairs of parallel edge sections enclose a right angle with each other. In order to avoid injury, the shape of the cover edge particularly preferably has rounded or inclined corners. This is expressed as "approximately rectangular".

[0024] The cover edges of the upper cover and the lower cover are preferably configured complementarily such that in the closed position, the housing is reliably shielded around the housing volume and relative to the external environment. The respective cover edges of the upper cover and / or the lower cover are preferably substantially planar. The cover edges of the upper cover and the lower cover are preferably planar at least 75% of their circumference. For example, due to the preferred configuration or arrangement of the hinge, a deflection is obtained, and the hinge pivotally connects the upper cover and the lower cover relative to each other. In order to form a mechanically particularly stable hinge, projections arranged at a certain distance from each other can be arranged in a zigzag manner on the upper cover and the lower cover, and the projections of the upper cover and the lower cover are arranged offset relative to each other along their spacing direction such that the projections of the upper cover and the lower cover are in a mating form-fit engagement with each other in the formed hinge. A metal rod extending along the spacing direction of the projections of the upper cover and the lower cover can then form a stable hinge axis of the hinge.

[0025] The upper cover and / or the lower cover can be manufactured by an injection molding method with favorable structural degrees of freedom, for example, from foamed polyurethane or from styrene copolymers valuable for their high impact resistance, i.e., for example, acrylonitrile-butadiene-styrene copolymer (ABS), or from a blend composed of such an ABS copolymer and another plastic, i.e., for example, polyamide or polycarbonate. The plastics used to form the upper cover and / or the lower cover can be filled with particles and / or fibers, especially glass fibers, to increase their strength.

[0026] The inner side of the upper cover and / or the lower cover can have a shell bottom with a main plane to simplify the arrangement of the corresponding shell on a flat base. If in doubt, this means that the inner and / or outer face parts of the cover bottom are formed planar. Thus, the planar outer part of the cover bottom can be used as a support surface for the cover on the base. Additionally or alternatively, 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 cover bottom with the main plane is inclined relative to the cover edge of the basic plane around an inclined axis. Thereby, the side wall, for example, the side wall arranged farther away from the machine operator when the operating module is in the operating state, can protrude farther from the operating panel of the operating module than the side wall arranged closer to the machine operator and opposite to the farther arranged side wall. Thereby, a certain degree of glare protection for the operating panel and its labels or display surfaces can be achieved.

[0027] Alternatively or additionally, due to the described inclination of the cover edge and the cover bottom, the operating panel is completely accommodated in the cover in a manner that it is inclined more strongly towards the machine operator than its inclination corresponding to the accommodation of the housing on the console of a floor processing machine or at other locations. Thereby, the accessibility of the operating surface can be simplified for the machine operator in the housing open position. Preferably, the operating module is arranged between the farther arranged side wall and the closer arranged side wall in a ready-to-work manner.

[0028] To achieve the above-mentioned favorably created self-centering effect, in a preferred improvement form of the present invention, the area of the cover bottom can be smaller than the opening area enclosed by the cover edge. However, due to the preferably main-plane formation of the housing bottom, it can be ensured that the cover is more reliably supported on the carrying base and that the cover is more reliably fixed on the carrying base.

[0029] The side walls extending from the cover edge to the cover bottom are inclined relative to the perpendicular bisector of the opening plane surrounded by the cover edge to provide concavity on the inner sides of the upper cover and the lower cover, and / or relative to the perpendicular bisector of the plane of the cover bottom. Preferably, the side walls of the upper cover and the lower cover opposite to each other with respect to at least one of the mentioned perpendicular bisectors also incline towards each other in the direction of the corresponding bottom, just like the outer wall of the operating module extending between the operating panel and the bottom of the operating module.

[0030] The inclination of the side wall and / or the outer wall can change one or more times in the direction towards the corresponding bottom, such that the side wall and / or the outer wall can be formed at least in sections to be curved around a curvature axis or bent around a bending axis, wherein the curvature axis or the bending axis can extend, on the one hand, for example, parallel or inclined to the corresponding bottom of the observed component of the upper cover or the lower cover and the operating module, and / or can extend parallel to the edge of the corresponding cover and the operating panel.

[0031] 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 set and anchored in a detachable manner as expected away from the lower cover on the prepared base on the bearing surface connected to the machine frame. Preferably, the upper cover is permanently and inseparably connected to the lower cover. In a continuation of the preferred embodiment, the upper cover and the lower cover can preferably pivot relative to each other about a virtual pivot axis. Preferably, the pivot joint providing pivotability between the upper cover and the lower cover, such as the hinge described above, forms the only permanent connection between the two covers, which is particularly preferred. The virtual pivot axis can be realized by a physical pivot axis or by other connection mechanisms known to those skilled in the art, which just allow the rotational movement freedom of the connected components.

[0032] In most cases, the floor processing machine moves in the forward direction along its rolling axis extending in the machine longitudinal direction during its intended floor processing operation. This does not exclude a curved movement trajectory around a curve. Then, the rolling axis is usually tangent to the current curved movement path of the floor processing machine or is near the tangent. Therefore, the operating module can preferably be arranged in a selective manner in the upper cover or the lower cover of the floor processing machine, such that the operating module can be in front of the machine operator at least in the forward direction during the operation of the floor processing machine. In the preferred arrangement, the reading direction of any Latin text markings of the operating elements on the operating panel extends in the machine transverse direction, that is, along the pitch axis of the floor processing machine.

[0033] In the preferred arrangement of the operating device, the virtual pivot axis extends between the upper cover and the lower cover in a plane having an angle of not more than 30°, preferably not more than 20°, with the rolling axis and / or the yaw axis of the floor processing machine. This plane preferably extends parallel to the rolling axis and parallel to the yaw axis. However, the virtual pivot axis can be inclined around a reference axis orthogonal to the yaw axis and can approach the supporting ground of the floor processing machine along the rolling axis.

[0034] Starting from the closed position, the upper cover and the lower cover can preferably pivot more than 90°, in order to ensure the ergonomic accessibility of the operation panel of the operation module arranged at one of the two covers. Preferably, the two covers can pivot relative to each other by at least 160°, particularly preferably at least 175°, and even more preferably pivot relative to each other between 178° and 182°.

[0035] In the above-described embodiment where the cover bottom and the cover edge or the operation panel and the operation module are inclined relative to each other about an inclined axis, the inclined 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 enclose a right angle.

[0036] The lower cover can be detachably connected to the support member as desired, and the support member carries the lower cover in the state where the surface processing machine is ready for operation. For this purpose, a locking mechanism can be formed at the carrying member, and a locking mating mechanism can be formed at the lower cover, and the locking mating mechanism can form a detachable form-fit connection. For example, one of the mentioned mechanisms can have a movable pawl, and when establishing the detachable form-fit connection, the movable pawl engages into the recess of the corresponding other mechanism and can be removed from the recess to disconnect the form-fit connection. Then, if desired, the housing and the operating device can be removed from the rest of the surface processing machine and stored at a safe location during the idle period of the machine.

[0037] The lower cover is preferably permanently connected to the carrying member, for example, by screwing and / or riveting and / or gluing. Although the screwing can also be detached as expected, due to the need for tools and the duration of the tool intervention for detaching the screwed connection, the effort for detaching the screwed connection is selected to be high so that the screwed connection is only detached within the scope of repairing the surface processing machine.

[0038] Compared with the permanent connection between the lower cover and the support member, the above-mentioned detachability as desired preferably relates to tool-free detachability, or in the case where tools are required, it relates to a tool intervention of less than 15 seconds to detach the support member of the lower cover.

[0039] The support member for carrying the lower cover or housing is connected to the machine frame. In principle, the support member can be firmly and rigidly connected to the machine frame. In order to further adapt the operating working space of the floor 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 mobility of the support member (e.g., a tray) relative to the machine frame can be translational, such that the machine operator can move the operating module towards or away from himself and / or such that the machine operator can move the operating module closer to or away from the side edge of the floor processing machine. Alternatively or additionally, the support member can be rotatably movable relative to the machine frame, such that the machine operator can place the operating panel in an orientation that is respectively advantageous for him.

[0040] In order to avoid undesired noise or mechanical loads, the upper cover can be detachably connected to the base in the open position, for example, connected to the above-mentioned support member, in particular detachably. For example, the upper cover can be lockable and / or magnetically connected to the support member against a force. In a particularly simple embodiment of the present invention, the upper cover can be loosely placed on the base in the open position.

[0041] In order to supply energy to the operating module and / or to transmit signals between the operating module and the data processing device arranged at the remaining part of the floor processing machine outside the operating device, at least one of the upper cover and the lower cover can have an opening, and in the ready-to-operate state, the electrical connection cable is guided through the opening to the operating module. If the operating module is to be directly connected to the energy source or to the 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 the other cover is to be connected to the energy source or the data processing device through the opening in this one cover, an opening in only one of the covers will be sufficient.

[0042] The establishment of the connection between the operating module accommodated in the housing and the energy source and / or the data processing device of the control device can be simplified by the following means: at least one of the upper cover and the lower cover has an external electrical connection port on its outer side, the external electrical connection port is used for electrically connecting to at least one on-board cable of the floor processing machine, and has an internal electrical connection port on its inner side that is conductively connected to the external electrical connection port, the internal electrical connection port is used for electrically connecting to the operating module. When the housing is arranged on the base of the floor processing machine, such as the above-mentioned support member, the external electrical connection port can be connected to the energy source and / or the data processing device via at least one on-board cable. The operating module arranged in the cover having the internal electrical connection port can be conductively connected to the internal electrical connection port.

[0043] Since 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 airborne cable.

[0044] The operating module preferably has an electrical coupling component for coupling with the electrical connection cable and / or a mating port for coupling with the internal electrical connection port.

[0045] If the operating device is detachably and connectably connected to the support member housing as expected, the external electrical connection port of the lower cover and / or the contact port on the support member side preferably includes 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. For the case where the external electrical connection port is arranged on the upper cover, the description of the connection port of the lower cover applies correspondingly to the external electrical connection port.

[0046] The same applies to the aforementioned direct connection of the operating module to the airborne electrical connection cable: preferably, the connection between the airborne electrical connection cable and the coupling component can be established and fastened without tools. For this purpose, one of the two components of the airborne electrical connection cable and the coupling component can be or have a plug, and the corresponding other component can be or have a socket, wherein preferably the plug and the socket are form-fittingly fastened to each other without tools, for example, by a union sleeve with a thread or a bayonet component to prevent accidental detachment.

[0047] In order to fasten the operating module at the cover selected for accommodating it, according to a preferred improvement, 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 mating component, wherein the placement component and the placement mating component can be placed in a form-fitting engagement that can be detached as expected to fasten the operating module at the cover of either the upper cover or the lower cover.

[0048] In a simple case, the placement component and the placement mating component can be formed as Velcro by arranging a fiber loop entanglement as the placement component at one of the operating module and the cover and arranging an elastic hook device as the placement mating component at the corresponding other component.

[0049] One of the mounting component and the mating mounting component may have a projection that engages, for form - fitting engagement, into a recess of the corresponding other component out of the mounting component and the mating mounting component. The projection may be configured as a clamp arranged at two ends or as a projecting projection. At least one of the mounting component and the mating mounting component may be transferred between a form - fitting engagement position and a release position so that a once - established form - fitting engagement can be disengaged as desired. The transfer between the form - fitting engagement position and the release position can only be carried out by expending force. To prevent unauthorized extraction of the operating module from the cover, the transfer may use a closing secret, such as a key, alphanumeric code, fingerprint, data, etc.

[0050] The mounting component and the mating mounting component are preferably arranged asymmetrically at their respective components: namely, the cover and the operating module, such that the operating module can only be inserted into the corresponding cover in a relative position with respect to the upper cover or the lower cover and can be secured there by a detachable form - fitting engagement.

[0051] To simplify the commissioning of a floor - working machine and especially the operating device, it can be proposed that at least one of the upper cover and the lower cover and the operating module be coordinated with each other such that when a detachable form - fitting engagement is established between the mounting component of the corresponding cover and the mating mounting component of the operating module, an electrical conductive connection is automatically established between the internal electrical connection port of the corresponding cover and the mating port of the operating module.

[0052] The above - described complementary configuration of the inner side of the cover and the outer side of the operating module that faces the inner side of the cover in the ready - to - operate state contributes to this coordination.

[0053] The coordination for automatically establishing an electrical 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 member and the placement mating member for the relative movement of the operating module and the housing when the operating module is arranged in the housing selected for the arrangement. This sequence can be achieved by corresponding physical and / or kinematic configurations of the placement member and the placement mating member. In addition to the above-mentioned elements, i.e., the protrusions and recesses (where at least one can be transferred between a form-fitting engagement position and a release position to establish a form-fitting engagement therebetween according to the intended disengagement), the placement member and the placement mating member can have a combination of fixed, form-fitting elements, i.e., protrusions and recesses formed at the housing and the operating module, which are immovable relative to the structures in the operating module and the housing that respectively carry them. Then, the movement process can be determined such that the combination of the fixed form-fitting elements must form a form-fitting engagement with each other at the two components, and then the form-fitting engagement only operates with a certain degree of freedom of movement in order to place the detachable combination of form-fitting elements in a form-fitting engagement that can be detached according to the intention. For example, the combination of the fixed form-fitting elements can include at least two protrusions protruding at a certain distance from each other at one component and two recesses or depressions arranged at the same distance from each other at the corresponding other component.

[0054] In principle, the operating module can have a data processing device configured to: process signals from sensors at the ground processing machine and control input signals from control elements and output control commands to actuators at the ground processing machine.

[0055] The control device of the ground processing machine preferably also has at least one data processing device arranged outside the operating module and carried by the mechanical frame, and the operating module can be connected to the data processing device to transmit signals. Thus, the operating module is increasingly used as an input module for inputting data and control commands. This reduces the cost 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.

[0056] A data processing device, which is arranged either within an operation module and / or outside the operation module in the remaining part of the ground processing machine, includes at least one processor, such as a microprocessor, and at least one memory. At least one program executable by the processor is stored in the memory, and the program is used to control the functional components of the ground processing machine. The data processing device includes at least one memory for storing data, i.e., for example, sensor data, data generated due to the actuation of one or more operating elements of the operation panel, and data for executing at least one program. The ground processing machine may have at least one or more sensors, which are connected to the data processing device in terms of signal transmission. The sensors detect the operating conditions of the ground processing machine, i.e., for example, its traveling speed, the position and state of the actuator, the steering angle of the traveling mechanism components, the spatial arrangement and / or orientation of the components of the ground processing device, any moving speed and / or moving direction of the components of the ground treatment device, etc.

[0057] In order to provide feedback on the operating state to the machine operator, the operation module preferably includes at least one output device for outputting signals and / or data. Such an output device may include a monitor, in particular a touch screen that can also be used as an input device, a speaker, a signal lamp, a haptic output device, i.e., for example, a vibrator, etc. Thus, the operation module can output data from the data processing device to the machine operator regardless of its location.

[0058] The housing has at least two covers, i.e., an upper cover and a lower cover. Thus, the housing can permanently accommodate at least two operation modules at the same time. Thus, on the one hand, the modules can be arranged in one cover or the other. To expand the function range, the above operation module can be a first operation module, and the control device also has a second operation module in addition to the first operation module. Each of the first operation module and the second operation module can then preferably be arranged in a ready-to-work manner in each of the upper cover and the lower cover, and is also actually arranged in the ready state of the ground processing machine.

[0059] The description above regarding the operation module or the first operation module equally applies to the second operation module. In particular, the electrically coupled components of the first operation module and the second operation module are identically configured. Since the internal electrical ports of the upper cover and the lower cover are also identically configured, the positioning of the first operation module and the second operation module in the lower cover or the upper cover can be freely selected. The operation panel of the second operation module is preferably different from the operation panel of the first operation module in terms of the type of operating elements arranged therein and / or the arrangement of the operating elements and / or the functional assignment of the operating elements, so as to provide different functions for the machine operator at the two operation modules and enable the machine operator to know at a glance: which of the two operation modules he is currently working at.

[0060] In principle, it is sufficient for the housing to have exactly one upper cover and one lower cover. However, a larger space for locally assembling at least one operating module can be provided at the surface processing machine in the following way: The housing has, in addition to the upper cover, a second upper cover and / or, in addition to the lower cover, a second lower cover. The housing preferably has more upper covers than lower covers, since the lower cover is preferably firmly connected to the base at least during the operation of the surface processing machine. Therefore, an embodiment with one lower cover and two upper covers is particularly preferred. The upper covers are preferably configured with the same upper cover volume, particularly preferably configured as identical components or as mirror-symmetrically configured members.

[0061] If the housing has, in addition to the upper cover, a second upper cover, the second upper cover and the lower cover can preferably pivot relative to each other about a second virtual pivot axis. Each virtual pivot axis for the relative pivoting of the upper cover relative to the lower cover is preferably realized at the straight edges of the lower cover and the upper cover. In order to be able to arrange at least one operating module in as large an area as possible at one cover at the surface processing machine, in the case of arranging two upper covers, the virtual pivot axis and the second virtual pivot axis are preferably formed at opposite edges of the lower cover.

[0062] If the second virtual pivot axis encloses an angle with the first virtual pivot axis, the two upper covers and the lower cover can ergonomically advantageously enclose the working space of the mechanical operator at the surface processing machine in a curved orientation. However, the angle is preferably not greater than 30°. Then, in the open state of the housing, the order from one end region of the housing via the two virtual pivot axes away from the other end region of the housing is: upper cover - lower cover - second upper cover.

[0063] In the currently particularly interesting surface processing machine, namely, for example, a slipform paver, the operating station usually extends linearly in the machine transverse direction. Therefore, the second pivot axis is particularly preferably oriented parallel to the first pivot axis. The housing is preferably configured mirror-symmetrically with respect to a 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 the two virtual pivot axes, and the virtual pivot axes define the two upper covers and the common lower cover.

[0064] The present invention can be particularly advantageously applied to a slipform paver. Description of the Drawings

[0074] Figure 9 Shows Figure 4 a schematic bottom view of the housing in Detailed Description

[0075] In Figure 1 a preferred embodiment of the surface working machine 10 (hereinafter also only referred to as "machine 10") in the form of a slipform paver according to the invention is schematically shown. The machine 10 includes a machine frame 12 which is carried by a traveling mechanism 14. The traveling mechanism 14 has a plurality of traveling gears which can roll on a supporting ground. In the example shown, the traveling gears are chain-type traveling gears with a surrounding chain. At least one or all of the traveling gears may be roller-type or wheel-type traveling gears. In the example shown, the traveling mechanism 14 has two front traveling gears 16 and one rear traveling gear 18. Instead of this configuration, two rear traveling gears may also be provided. The rear traveling gear 18 can be positioned along the traveling gear support 20 in the machine transverse direction Q or opposite to the machine transverse direction along the pitch axis Ni by a respective servo motor.

[0076] 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.

[0077] 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 .

[0078] 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.

[0079] 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.

[0080] 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 1Depending on the different schematic diagrams, it can also be installed on the opposite right mechanical edge. The machine operator working on the cab 38 spends most of his working time on the cab 38 observing the concrete molded body flowing out of the slip form 28. Therefore, the machine operator mainly stays in the end region of the cab 38 closest to the slip form 28.

[0081] Control devices 40 are arranged on the cab 38 to control the machine 10. The control devices include two housings 42 and 44 and two operation modules 46 and 48.

[0082] The two housings 42 and 44 are arranged side by side along the pitch axis Ni and are constructed mirror-symmetrically with respect to a symmetry plane orthogonal to the pitch axis Ni. By considering the said mirror symmetry, the following description of the housing 42 is sufficient, and the description of it by considering the symmetry conditions also applies to the housing 44.

[0083] Figure 1 Each of the housings 42 and 44 in has a lower cover 52 fixedly connected to the 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-symmetric 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.

[0084] In Figure 1 the corresponding open states of the two housings 42 and 44 are shown. The operation modules 46 and 48 are only located in the housing 42 here. Specifically, the operation module 46 is located in the lower cover 52 of the housing 42 and the operation module 48 is located in the upper cover 54.

[0085] In Figure 2 the separate state of the cab 38 and its access part 36 is shown, where the housings 42 and 44 are also in their corresponding open states. In Figure 3 it shows the cab 38 and its access part 36 in the same perspective view as Figure 2 but the housings 42 and 44 are in the closed state.

[0086] In Figure 2 and Figure 3 the frame 56, which is part of the cab floor 58, is shown. The frame can be fully seen in Figure 1 The machine operator is located on this cab floor 58 during his operation to control the normal operation of the surface working machine 10.

[0087] The upper cover 54 and the lower cover 52 can pivot relative to each other about the pivot axis P between the closed position shown in Figure 3 and Figure 2They are pivotable relative to each other by approximately 180° between the open positions shown. For the sake of clarity, the pivot axis P is shown only at the hinge 60 of the upper cover 54 and the lower cover 52 on the connection of the housing 42. The pivot axis P lies in a plane extending parallel to the plane spanned by 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 parallel to the yaw axis Gi.

[0088] Figure 2 The inner side 52a of the lower cover 52, which is concave with respect to each of two mutually orthogonal spatial directions, and the inner side 54a of the upper cover 54, which is concave with respect to each of two mutually orthogonal spatial directions, are shown according to the housing 44 not occupied by the operating module. Possible design options for the lower cover 52 and the upper cover 54, which also apply to the housing 42, are shown Figure 2 at the housing 44 in

[0089] Figure 2 The operating module 48 in

[0090] can be connected to the operating module 46 for signal and energy transmission via a connecting cable 62. The operating module 46 is then the only operating module that is connected to the on-board 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 console 50 of the cab 38 of the machine 10 or at another suitable location.

[0091] The internally electrical connection port 68, which is only schematically shown, may have a physical structure 68a protruding away from the bottom 52b of the housing. The operating module may 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 internally electrical connection port 68 extends into the recess of the mating port on the operating module side, wherein the lower or upper housing may have the same internally electrical connection port 68 to ensure the arrangeability of the operating module in the two housings 52 and 54. Obviously, the assignment of the protrusion and the recess may be selected differently from the illustrated embodiment. To ensure that the operating module 46 or 48 can be arranged on a seat in another plane different from the bottom of the lower cover 52 or the upper cover 54 without tipping over or wobbling, it is preferred that: the physical structure 68a is formed in the internally electrical connection ports of the covers 52 and 54 and the recess corresponding to this structure and accommodating the physical structure is formed in the mating ports of the operating modules 46 and 48.

[0092] The internally electrical connection port 68 has contact means 68b, such as spring contact pieces, which contact the mating contact means on the operating module side when the internally electrical connection port 68 is connected to the mating port of the operating module, since the connection port 68 and the mating port are complementary formed.

[0093] The spring-preloaded locking latch 68c can engage into a corresponding locking recess in the mating port of the operating module, thereby firmly fixing the operating module at the corresponding cover in a form-fitting manner. The spring-preloaded locking latch 68c is part of the mounting member 70, and the locking recess is part of the mounting mating member on the operating module side. The locking latch 68c can be retracted into the physical structure 68a of the internally 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 means of a linkage.

[0094] In Figure 3 the housings 42 and 44 are shown in the closed position, in which they completely surround the operating module accommodated therein or the internal space surrounded by the concave inner sides 52a and 54a.

[0095] In Figure 3 it is only shown in dashed lines that the upper cover 54 of the housing 42 may have a hole 66 as a cable feed-through for connection to Figure 2The views differently guide the on-board connection cable 72 passing through the console 50 through the hole 66 and connect it to the operation module 48 accommodated in the upper cover 54 in a manner of transmitting signals and energy. The plug 72a at the free longitudinal end of the on-board connection cable 72 forms a first on-board port for connecting the operation module 46 or 48 to the on-board energy supply device of the machine 10 and / or to the on-board data processing device 64.

[0096] On Figure 3 An external electrical connection port 74 is shown on the outer side of the operation module bottom 54b of the upper cover 54 of the housing 44 in []. The external electrical connection port has a recess or a concave portion 74a in the operation module bottom 54b on the outer side of the operation module bottom. The external electrical connection port 74 is constructed in principle like the mating port of the operation module described above, because the external electrical connection port 74 is configured to mechanically and electrically couple with two on-board ports 76 on the base 50a of the console 50, which is used as a support member and is covered in the open state of the housing 44, in the same way as the mating port of the operation module for mechanical and electrical coupling with the internal electrical connection port 68.

[0097] The external electrical connection port 74 on the outer side of the operation module bottom 54b is configured to be smaller than the internal electrical connection port 68 on the inner side of its operation module bottom 54b and is completely covered by the larger-area internal electrical connection port 68 when observed orthogonally to the operation module bottom 54b, wherein the external electrical connection port is also an external mechanical connection port like the internal electrical connection port 68 described above. The electrical mating contact device 74b at the external connection port 74 is used for electrical contact through the contact device 76b at the physical structure 76a of the second on-board port 76. In Figure 3 the extended position shown in [], the spring-preloaded locking latch 76c is used to temporarily fasten the upper cover 54 above the base 50a in a form-fitting manner in the open position of the housing 44.

[0098] The contact of the mating contact device 74b is directly connected to the contact of the contact device 68b on the inner side of the upper cover 54. Therefore, when the upper cover 54 is in the expected locking engagement with the second on-board port 76 via its external electrical connection port 74, the operation module arranged on the concave inner side 54a of the upper cover 54 is electrically connected to the on-board energy supply device of the machine 10 and electrically connected to the on-board 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 on-board port.

[0099] In addition to being smaller in size, the second on-board port 76 is configured like the internal electrical connection port 68, so the description thereof can also be used for the second on-board port 76, where only the number 68 is replaced by the number 76. The physical structure 76a is complementarily configured with the recess 74a of the external electrical connection port 74 and extends into the recess 74a of the upper cover 54 in the open position of the housing 44.

[0100] In the embodiment, the upper cover 54 of the housing 42 equipped with the operation modules 46 and 48 is only placed flat on the support buffer 78 at the console 50 in an unlocked manner in the open position. The different views of the designs 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 configured identically within the scope of the above mirror design scheme.

[0101] In Figure 4 , the housing 42 and the operation modules 46 and 48 accommodated therein are shown separately. The operation modules 46 and 48 each have display devices 46a and 48a for displaying data and for outputting information. The display devices 46a and 48a are configured differently and are used for different visual information outputs during operation. In addition, each of the operation modules 46 and 48 has its own operation panel 46b or 48b, and the operation panel has operation elements separately arranged thereon. See, for example, operation elements such as toggle switches 49a, pressure switches 49b, and rotary switches 49c. The operation panels 46b and 48b have the same total area. The operation elements of the two operation panels 46b and 48b are different in terms of their arrangement on the operation panel and in terms of their functions and operation types. Although mainly toggle switches 49a and only a few rotary switches 49c and pressure switches 49b are arranged on the operation panel 46b, the main rotary switches and pressure switches 49c or 49b are arranged on the operation panel 48b.

[0102] In principle, the operation panels 46b and 48b can be configured to operate different mechanical functions. For example, concrete equipment, including but not limited to material conveying devices, tank control devices, vibrators, etc., can be controlled by one of the operation modules 46 or 48, and the mechanical kinematic components, including but not limited to the travel drive 24, the height adjustment device of the lifting column 14a, and the steering positioning devices of the transmission devices 16 and 18, can be controlled by the corresponding other operation module 48 or 46. There can also be functions that can be controlled at each of the operation modules 46 and 48.

[0103] The operation panels 46b and 48b on which the operation elements are mounted are substantially flat, and in the example shown, they are aligned parallel to the bottoms 46c and 48c of the operation modules 46 or 48 (see also Figure 8 ).

[0104] The upper cover 52 and the lower cover 54 are delimited by cover edges 52c or 54c, which are in planar contact with each other in the closed position of the housing. The cover edges 52c and 54c are respectively planar cover edges, that is, they are respectively located in a plane. The cover edges 52c and 54c are preferably coplanar in the open position of their housings 42 and / or 46, as is the case in Figure 4 and Figure 7 the case.

[0105] As can be recognized in Figure 4 and 7 : The planes of the cover edges 52c and 54c are inclined relative to the planes of the respective cover bottoms 52b and 54b about an inclination axis N. In the state where the housings 42 and 44 are arranged ready for operation at the operating console 38, the inclination axis N preferably extends parallel to the pitch axis Ni on the side on which the working space W of the mechanical operator of the housings 42 and 44 lies (see Figure 2 and 3 ). In the views of Figure 4 and Figure 7 , the inclination axis N is shown closer to the housing 42 compared to the actual situation. Figure 3 shows a more realistic position of the inclination axis N relative to the housings 42 and 44.

[0106] Therefore, the side walls 52d and 54d of the lower cover 52 or the upper cover 54 that are arranged further away from the mechanical operator and extend along the pitch axis Ni project further upward from the respective cover bottoms 52b or 54b compared to the side walls 52e and 54e that are also arranged along the pitch axis Ni and are closer to the mechanical operator. Therefore, the side walls 52d and 54d that are arranged further away from the mechanical operator project more beyond the operating panels 46b and 48b of the operating modules 46 or 48 accommodated in the respective covers 52 and 54 than the side walls 52e and 54e. Therefore, a certain level of glare protection can be achieved for the operating panels 46b and 48b relative to the light sources arranged in front of the machine 10. Additionally, the housing 42 can thus be closed without the operating elements protruding from the respective operating panels 46a and 48a colliding with each other or with the operating panel of the respective other operating module.

[0107] Figure 5 shows the same arrangement as Figure 4 , but is shown from an oblique front. In Figure 5Shown outside the side walls 52d and 54d is a damper 80 that connects the two covers 52 and 54 to each other at their hinge points 81a and 81b. The damper limits the pivoting speed of the covers 52 and 54 relative to each other to prevent the upper cover 54 equipped with the operation module 48 from hitting the support buffer 78 at high speed and decelerating extremely there under the action of a high force. Thus, the electronic devices in the operation module 48 can be protected from undesired 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 housed inside the cylinder 80a. Therefore, the flow resistance increases approximately quadratically with the flow velocity at the flow obstruction, such that the braking action exerted by the damper 80 on the housing covers 52 and 54 gradually increases as the relative pivoting speed of the two housing covers 52 and 54 increases.

[0108] Side walls 52f and 52g of the lower cover 52 that face each other along the pitch axis Ni and side walls 54f and 54g of the upper cover 54 that face 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 cover and the lower cover marked with the same lowercase letter are connected to each other above their respective side edges marked with the lowercase letter "c".

[0109] In Figure 6 is shown the Figure 5 housing 42 in a semi-open position between the open and closed positions.

[0110] In Figure 7 are shown the operation modules 46 and 48 without the housing 42. The operation 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 operation modules 46 and 48 currently, because their descriptions apply to each of the other operation modules as well, except for the corresponding different operation panels 46b and 48b.

[0111] The operating module 46 has an edge 46d from which the outer walls of the operating module 46, see for example outer walls 46e and 46h, extend towards the bottom 46c of the operating module 46. The outer walls of the operating module 46 enclose 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 in the area of the operating module 46 that is closer to the machine operator during operation. In the area of the operating module 46 that is further away from the machine operator during operation, the edge 46d projects beyond the operating panel 46b at an interval therefrom, such that handle recesses 46f and 46g can be formed on the outer wall 46e of the operating module 46 that points away from the machine operator along the rolling axis Ro during operation, and the handle recesses simplify the insertion of the operating module 46 into one of the covers 52 and 54 and the removal of the operating module 46 from the corresponding cover.

[0112] The outer shape of the operating module 46 tapers from the edge 46d to the bottom 46c, such that the outer shape of the operating module 46 has a generally convex outer shape, and the convex outer shape is adapted to the concave inner sides 52a and 54a of the housing 52 or 54. In order to be able to provide the convex outer shape, the lateral outer wall 46h, for example, has a bent section 46h1 that is formed to bend around a curvature axis KM. Due to the convex outer 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.

[0113] The lateral outer wall sections 46h2 and 46h3 below or above the bent section 46h1 are substantially planar and are inclined relative to each other around the curvature axis KM due to the bent section 46h1 located therebetween.

[0114] A locking mechanism 82 with a locking claw device 82a is arranged at the outer wall 46e as part of the placement mating component 71. By means of a button 82b, the locking claw device 82a can be placed in a release position in which the locking claw device releases the locking pin 84 shown in the placement component 70. Figure 8 The locking claw device 82a is adjusted, for example, by a dead - center kinematic device such that when the locking pin 84 is introduced into the locking claw device 82a, it is transferred by the locking pin 84 into a form - fit engagement position surrounding the locking pin 84 and remains there until the button 82b is actuated. Instead of or in addition to the above - mentioned connection port 68, the operating module 46 can be mechanically and firmly arranged in one of the lower cover 52 and the upper cover 54 by means of the locking mechanism 82 and the locking pin 84 through form - fit engagement.

[0115] The locking pin 84 projects, for example, from each of the side walls 52d and 54d towards the respectively opposite side walls 52e and 54e. Due to this asymmetrical arrangement, the operating module can only be arranged in exactly one relative position in one of the covers 52 and 54.

[0116] The side walls of the housing covers 52 and 54 are also inclined to provide a concave inner side and enclose an angle greater than 90° with the bottom 52b or 54b.

[0117] Figure 8 and Figure 9 The bending axes KS1 to KS6 are shown, and the adjacent sections of the side wall of the upper cover 54 on both sides of the respective bending axes are bent relative to each other about the bending axes. The bending axes KS1, KS2, KS5, and KS6 extending along the side walls 54f and 54g are symmetrically formed with respect to the central vertical plane MSE orthogonal to the drawing plane on the cover bottom 54b and are 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 ready-to-operate state. The side wall sections 54e1, 54f1, and 54g1 arranged closer to the cover bottom 54b are bent less relative to the cover bottom 54b than the more remotely arranged side wall sections 54e2, 54f2, and 54g2 of the respective same side walls 54e, 54f, and 54g. Figure 9 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 region close to the cover bottom 52b of the lower cover 52. However, the side walls 52e, 52f, and 52g have the same inclination angle relative 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 applies to

[0118] the side walls 52d and 54d not shown in Figure 8 and Figure 9 This ensures that sections of the outer walls of the operating modules 46 or 48 abut against the inner sections of the side walls 52d, 52e, 52f, and 52g as well as 54d, 54e, 54f, and 54g with a small clearance or preferably without play.

[0119] As Figure 7 shown, the operating modules 46 and 48 have coupling components 86 in addition to or instead of mating ports coupled to the internal electrical connection ports 68, and the coupling components can be coupled to the plugs 72a of the on-board cables 72 in order to supply electrical energy to the coupled operating modules and in order to ensure signal transmission with the on-board data processing device 64. The coupling components 86 are configured for quick coupling with the plugs 72a at the on-board connection cables 72. The plugs 72a can be firmly seated at the coupling components 86 in a form-fitting manner by means of a bayonet lock or a union nut.

[0120] In addition, the operation module has a forwarding port 88, as Figure 2 shown, via which another operation module can be connected to the operation module directly connected to the on-board connection cable 72 via a connection cable 62 to supply electrical energy and to transmit signals. The connection cable 62 can be connected at one end to the forwarding port 88 of this operation module and at the other end to the coupling component 86 of another operation module. The forwarding port 88 is also a quick-connect port, which has, for example, a bayonet- or pipe-nut-securing device for establishing an electrical connection once and for all.
