Description

[Technical field]

[0001] The present invention relates to a work vehicle for performing work input on a track, the work vehicle comprising a vehicle frame supported on a rail traveling device and capable of traveling on a track, a traveling cabin connected to the vehicle frame, and various structures having assigned functions for work input. In addition, the present invention relates to a method for assembling the work vehicle. [Background technology]

[0002] A work vehicle according to the generic term is known from AU 520 066 A1. A work platform and a crane with a work basket are arranged as structures with assigned functions. During work, the vehicle is supplied with electrical energy from a number of energy storage modules (battery packs).

[0003] Austrian utility model 16702 discloses a similar work vehicle, in which the supply by an energy accumulator module is also implemented. With respect to length, the structure of the work vehicle is divided into sections. One of these sections is a walkable cab, in which the energy accumulator module is accommodated. By varying the arrangement of the modules, different enclosure heights and thus different space heights can be achieved. In this way, it is possible to provide a recess in the vehicle roof, into which the work platform can be lowered during the shutdown position. Summary of the Invention [Problem to be solved by the invention]

[0004] The object of the present invention is to improve the above-mentioned type of work vehicle in such a way that different structures can be arranged efficiently on the vehicle. Furthermore, the object of the present invention is to provide a corresponding method for assembling the work vehicle. [Means for solving the problem]

[0005] According to the invention, this problem is solved by the features of the independent claims 1 and 13. The dependent claims present advantageous configurations of the invention.

[0006] In this case, the structures are formed as free-standing functional modules with predefined interfaces and are connected to the vehicle frame and / or to each other by means of screw connections. The functional modules are characterized by their inherent functions, inputs and outputs, by system limits and predefined interfaces, as well as by their interaction with the other functional modules and the overall machine functions. Such free-standing functional modules are preassembled and thoroughly checked before being installed in the work vehicle. In some cases, the surfaces of the modules are also painted in advance, so that the vehicle is already ready for operation after the modules are installed. The predefined interfaces allow the interconnection of different functional modules without further adaptation. The pre-checks are carried out using a diagnostic device with the same predefined interfaces. In particular, the diagnostic device has a universal measuring and inspection device, connecting elements for the mechanical installation of the respective free-standing functional modules, and a control device for operating the various functional modules. Module diagnosis and system testing before installation optimizes the time required for the start-up of the vehicle. All modules are run through and checked for module geometry and module function to enable joinability during final assembly without welding and fitting processes.

[0007] The vehicle according to the invention exhibits high operational reliability due to comprehensive module checks and possible corrections. Error costs are minimized due to early error recognition during module checks and system authentication after the modules are installed. In addition, the usage limits of the individual functional modules are given and can be checked in advance. The interactions of the module functions are also known in advance. The smaller number of component variants compared to known vehicle concepts further increases operational reliability.

[0008] When the arrangement of functional modules is changed, a single upfront type inspection and conformity marking leads to simplified subsequent approval. The use of conformity marks instead of multiple individual type inspections and faster assembly reduces the time required for the production process. New module combinations make it possible to easily extend the vehicle's functionality and range of use with new functions.

[0009] In particular, the elimination of traditional mechanical construction and the avoidance of welding operations during final assembly contribute to the avoidance of errors. Overall, the modular construction offers simplified maintenance operations and easy retrofitting of technical adaptations. At the end of its life cycle, simple dismantling and recycling of the raw materials are possible.

[0010] Advantageously, the predefined interfaces are formed as mechanical and electrical and / or hydraulic and / or pneumatic interfaces. The interfaces of the individual functional modules are connected to one another directly or by means of modular lines. These lines are positioned in defined channels and line guides and fixed in position at the interfaces, which are formed, for example, as connectors, flanges or quick couplings. In particular, the interfaces serve for mounting, energy supply, communication and diagnostics of the individual functional modules. A corresponding diagnostic device meaningfully has universal interfaces for electrical systems, hydraulic systems, compressed air, fuel, water, oil and various auxiliary substances (for example urea solution for internal combustion engines).

[0011] In a further refinement, the predefined interfaces have connecting elements, which in particular allow the adjustment of the respective functional module in two mutually perpendicular directions. This ensures an exact positioning of the modules during final assembly. The mechanical interfaces or connecting elements can be precisely matched and fixed by means of a screw connection. This makes it possible to dispense with welding operations during final assembly. The connecting connections compensate for volumetric and length expansions, for example due to thermal expansion. During final assembly, the individual functional modules are connected to one another one after another on the vehicle frame, which serves as a platform, the defined mechanical interfaces being used for mounting. For example, the mounting is carried out via a hole pattern with a screw connection and elastic suspension. Unique connecting locations are assigned, so that collisions of the components are avoided.

[0012] In one development, the predefined interface has connecting elements with a unique geometrical fitting shape, by means of which a unique connection is predefined, so that interface errors are avoided. Preferably, the principle of error proofing is used, for example shape coding for setting a unique pose position.

[0013] Advantageously, the vehicle frame has two lateral longitudinal beams, the upper edges of which define the vehicle floor, and at least one functional module is arranged below the vehicle floor as an underfloor module, whereby the vehicle floor can be considered as a partition plane between the spaces for above-floor mounting of the functional modules and the spaces for below-floor mounting of the functional modules. The respective mounting spaces are variable in terms of size and shape by the arrangement and dimensioning of the longitudinal beams. The arrangement of the transverse beams, which are rigidly connected to the longitudinal beams, also influences the respective mounting spaces.

[0014] Advantageously, each longitudinal beam has a longitudinal beam upper chord and a longitudinal beam lower chord, which are connected to each other by a number of connecting elements arranged at equal intervals from each other. In this case, the structural form of the lower chords together defines the space for underfloor mounting. Each lower chord is connected to the assigned upper chord via a connecting element (strut) in a standardized manner. This design enhances the bending, tension-compression and torsional stiffness of the frame without restricting the mounting space for the functional modules.

[0015] In one advantageous development of the invention, an underfloor module is configured as a traction module, which has an internal combustion engine that is connected to an electric generator and / or a pump distribution gearbox, and which drives the vehicle and also supplies energy to the further functional modules.

[0016] Advantageously, at least one functional module is configured to be movable on a guide relative to the vehicle frame, by means of which the position of the vehicle's center of gravity can be shifted in order to optimize the weight distribution on the rail-mounted running gear, for which the corresponding functional module can be shifted in the longitudinal and transverse directions in a stepped or non-step manner.

[0017] Preferably, the movable functional modules, e.g. tanks, power packs, etc., are mounted on an auxiliary frame, in which case the change of the mounting position in the lateral direction is effected by a lateral movement of the respective functional module on the auxiliary frame.

[0018] In another refinement of the invention, the vehicle frame is divided longitudinally into three sections, with a travelling cabin arranged on one end section, a crane module or another cabin arranged on the other end section, and further functional modules built on the central section. With this longitudinal building block concept, the mounting space for mounting the functional modules is fixed in width and variable in length and height. In particular, the central section is variable in the longitudinal direction to allow the arrangement of different functional modules.

[0019] For an advantageous arrangement of the selected functional modules, the mounting space, given by the dimensions of the vehicle frame and the construction clearance to be observed, is divided into vertical, longitudinal and transverse segments, preferably four segments (e.g. bogie, cabin, roof structure and underfloor assembly) arranged vertically, ten segments (e.g. shock absorbers and towing hooks, cabin, crane, loading surface, etc.) arranged longitudinally and three segments (e.g. driver's seat, passenger seat, etc.) arranged transversely.

[0020] In a further development, a modular control software is provided in the control device, in which different functional modules are assigned specific software modules, which can be delimited separately. This modular concept of the control software is adapted to functional modules that can be selected from a predefined module catalog, and the control software can be adapted to the respective configuration of the machine functions.

[0021] In the method according to the invention for assembling the described work vehicle, the vehicle frame is manufactured with dimensions adapted to the selected functional modules, each functional module is first preassembled as a free-standing unit, and the preassembled functional modules are screwed to the vehicle frame and / or to each other, where the vehicle frame serves as a platform, which can be modified and scaled according to defined standards with regard to width, length and height.

[0022] Further advantages result from the smaller number of component variants compared to conventional vehicle concepts. Manufacturing costs are reduced and logistics are simplified by the minimal stock management of functional modules and modular components. The high level of detail allows easy understanding and unique assignment of mounting configurations and individual parts. The mounting concept offers a high number of repetitions and common parts with fewer standard variants are used. In addition, CAD mounting tools (e.g. 3D representations of the individual components in the mounted state or virtual or augmented reality as mounting aids) are simplified and allow standardized mounting.

[0023] In one development of the method, each preassembled functional module is run on a diagnostic device before installation. Thus, before installation, a geometrical and functional check is carried out on each functional module in order to eliminate possible errors or weak points. In particular, module diagnostics is a method using a test device for quantitative measurement and evaluation of individual functional modules and qualitative evaluation of the functional system for final assembly. The quality assurance achieved thereby and the consistent validation by rapid test methods for quantitative performance assessment of the functional units are used for evaluation and documentation for traceability management and obsolescence management.

[0024] In a further improvement, the modular control software provided in the control device is adapted to the integrated functional modules. For each selected and assembled functional module, a corresponding part of the control software is activated and released. This facilitates structured programming of the machine control. In addition, adaptation to changed requirements and legal requirements by replacing individual functional modules and control units can be easily carried out.

[0025] The invention will now be described, by way of example only, with reference to the accompanying drawings, in which: [Brief description of the drawings]

[0027] 1 to 3 show an exemplary vehicle frame 1 for a work vehicle 2 based on a modular building block system. The main elements of the vehicle frame 1 are two lateral longitudinal beams 3, each of which has one upper chord 4 and one lower chord 5. Each upper chord 4 and the corresponding lower chord 5 are connected by a number of connecting elements (struts) 6, which are equidistantly spaced from one another in the vehicle longitudinal direction 7. A standardized scaling of the vehicle frame 1 is provided in advance so that vehicle frames 1 of different lengths can be manufactured with it.

[0028] The vehicle frame 1 is divided into two end sections 8 and a central section 9 located between them. In each end section 8, the longitudinal beams 3 are rigidly connected to transverse beams 10. In these transverse beams 10, rotation pins and supports for modularly constructed rail running devices 11 are arranged. Optionally, in the central section 8, another transverse beam 10 is positioned as a support for a crane module 12. The position of this transverse beam 10 is freely selectable in the longitudinal direction 7 along the scaling preliminarily given by the connecting elements 6. In particular, the respective lower chords 5 are arranged only in the central section 9.

[0029] According to the invention, the dimensioning of the vehicle frame 1 is adapted to the selected functional modules 11-22. This selection is derived from the predefined vehicle requirements. In the design phase carried out in advance, a module catalog is created. In the module catalog, each functional module 11-22 is defined with all its functions and predefined interfaces 23. A further determination of all possible functional modules 11-22 and their possible combinations is carried out in order to meet the specification settings. This requires that positioning conditions and service limits are observed (gauge, track gauge, track grade, standards and regulations). Exclusion criteria for impossible combinations are also defined. Advantageously, in a computer-implemented module configurator, corresponding algorithms are used. With this, the functional modules 11-22 and machine functions can be combined in an automated manner, taking into account the service limits, the technical life span and the exclusion criteria. In the case of this automated module configuration, the country-specific circumstances are also taken into account. In order to provide cost and price building blocks, the module configurator can be extended by cost calculation algorithms. Additionally, the virtual configuration of the vehicle 2 by a CAD algorithm for selecting module combinations from a module library is useful.

[0030] The standardized functional modules 11-22 can be combined with one another according to a building block system and can be partially scaled with respect to size and range of functions. In addition to the rail-mounted module 11 and the crane module 12, for example, the lifting platform module 13, the traction module (power pack) 14, the tank module 15, the overhead line and energy supply module 16, the workshop module 17, the welfare cabin module 18, the technical room module 19, the load surface module 20 and the travelling cabin 21 as well as various further modules 22 can be selected as functional modules. The modules 11-22 can be scaled in particular to the customer-specific requirements. For example, in the case of a crane, the lifting load and the boom radius can be changed.

[0031] Each of these functional modules 11-22 is formed as a self-supporting unit with a predefined interface 23. In order to reduce the vehicle weight and increase the number of modules 11-22 that can be installed, lightweight construction is used, taking into account the maximum permissible axle load and the respective track class. For example, the cabins 17, 18, 19, 21 are manufactured from an aluminum wrought alloy. In spade construction, laser-cut and folded aluminum sheets with a thickness of 5 mm to 10 mm are assembled. In addition, the use of high-strength, fine-grained structural steel reduces the material thickness and the vehicle weight.

[0032] Depending on the function of the respective module 11-22, the predefined interfaces 23 have mechanical, electrical, hydraulic, pneumatic and other connections. In particular, data interfaces for communication with the other modules 11-22 and with a central control unit 24 are provided. The individual modules, for example the traction module 14, are preferably mounted on an auxiliary frame 25. In this case, all relevant components for the respective functional unit are spatially compactly arranged. The functional modules 11-22 thus configured are easily transportable and can be positioned and mounted by a crane or a lifting device. The high level of design detail and the unique structure allow the prefabrication of the functional modules 11-22 at different manufacturing locations. A consistent change management ensures history tracing. In addition, a standardized retrofit and upgrade management for the continuous technical updating and standard-compliant adaptation of existing vehicles is carried out in order to ensure a long service life.

[0033] For a new vehicle 2, the basic type and the drive concept are first determined. For example, a choice is made between two single axles and two bogies for the base rail travelling gear 11. The base vehicle 2 consists of two rail travelling gears 11, a vehicle frame 1 with integrated modules for traction and travelling operation, a travelling cabin 21 with the vehicle control unit, a standard-compliant workspace for the vehicle driver and free space for the functional modules 11-22. The minimum equipment in the modules 11-22 for performing the basic functions of driving and stopping is also determined. In this case, all functional modules 11-22 can be used both for two-axle and for four-axle platforms.

[0034] The vehicle frame 1 serves as a platform on which selected functional modules 11-22 from the modular building block system are built during final assembly. The upper chord 4 is then a standardized main beam with defined interfaces in the longitudinal direction 7. On each side, between the upper chord 4 and the lower chord 5, there is a free space 26 for maintenance components. On the outside, cable trays 27 are arranged over the entire length of the vehicle. The upper edges of the longitudinal beams 3 define the vehicle floor 28, which divides the mounting space into an upper and a lower area. As can be seen in FIG. 3, between the longitudinal beams 3, there is a free space 29 for underfloor mounting. The optional central transverse beam 10 and the connecting elements 6 have penetrations for line guides. Preferably, the line guides are positioned in the area of ​​the lower chord at the side and provide space for cable harnesses, hydraulic lines and pneumatic lines. The standardized design of the functional modules 11 to 22 allows for variable mounting locations on the basic frame 1.

[0035] The assembly of the work vehicle 2 will be described with reference to Figs. 4 to 6. Firstly, a distinction is made between an underfloor mounting space 29 and an above-floor mounting space 30. A traction module 14 for the operation of the vehicle 2 is preferably arranged under the floor (e.g. bogie, power pack, transformer, accumulator, etc.). In this case, the traction module 14 comprises, for example, a prime mover, a generator, an electric drive and possibly a brake energy recovery device. In addition, the traction module 14 is connected to an overhead line-energy supply module 16. Additionally, for example accumulators, fuel cells and other new energy sources (solar installations) are arranged.

[0036] On the vehicle floor 28, for example, the technical room 19, the travelling cabin 21, the electrical enclosure, the passenger cabin 18, the workshop 17, the crane 12 and the lift platform 13 are arranged. In the front area 31 and in the rear area 32, shock absorbers and coupling devices are provided, by means of which towed vehicles can be coupled or several vehicles 2 can be coupled to each other. In addition, there is the possibility of mounting attachment modules 22 for special functions (snow removal equipment, measuring devices, etc.). On the roof of the cabin 21, there is space for roof structures 16 (for example current collectors, braking resistors, lines, etc.).

[0037] In the vertical direction 33, the modules 11-22 are mounted one above the other in four segments. Starting from the bottom, the first segment comprises, for example, the rail running gear 11. The second segment between the lower chord 5 and the upper chord 4 serves, for example, to accommodate the traction module (power pack) 14, the transformer module, the accumulator module and the tank module 15. In the third segment on the vehicle floor 28, for example, the cabin 21, the crane module 12 and the lifting platform module 13 can be arranged. The fourth segment on the roof comprises, for example, the current collector, the braking resistor and various working equipment, for example line pushers.

[0038] In the lateral direction 34, the mounting of the modules 11-22 is preferably carried out in three segments. On the outer left and outer right, maintenance ducts for, for example, line guides are arranged. In between, there are segments for functional assemblies.

[0039] In the longitudinal direction 7, a division into up to ten segments is carried out, in which, for example, one after the other, shock absorbers and towing hooks, a travelling cabin 21, a welfare cabin 18, a workshop cabin 17, a lift platform 13, a loading surface 20, a tool room, a crane 12, a crane cabin and again shock absorbers and towing hooks are arranged.

[0040] FIG. 6 shows one variation of the mounting positions of the functional modules 11-22 in the vertical direction 33, the longitudinal direction 7 and the transverse direction 34. For example, a tank module 15 is mounted on an auxiliary frame 25. In this case, a lateral movement of the tank module 15 on the auxiliary frame 25 allows a change of the mounting position in the transverse direction 34. A change of the mounting position in the longitudinal direction 7 is carried out by a movement of the auxiliary frame 25 on the vehicle frame 1 along a guide. A movement of the module 15 in the vertical direction 33 along the connecting element 6 between the upper chord 4 and the lower chord 5 causes a change of the mounting position.

[0041] Before the final assembly of the modules 11-22, a module diagnostic is carried out. The modules checked in this way are joined together similarly to the building brick principle and connected by form and force connections. The same applies to the fitting of the lines and additional equipment. The orientation and positioning are in this case uniquely predefined and are forced, for example by shaping that is coordinated with one another. Each joining step is checked with the aid of a checklist and is inspected and verified during self-inspection by the worker. The system function is checked and certified by machine evaluation after the joining of the modules 11-22 and the connecting lines.

[0042] Within the scope of the module diagnostics, quantitative measurements and evaluations of the individual modules 11-22 and qualitative evaluations of the functional systems are carried out for final assembly. For example, in the case of the traction module (power pack) 14, the following checks are carried out: -Electrical input and output measurements -Electrical analysis of the signal - Media flows: Check fuel, coolant, additives, cooling air flows - Hot measurement of an internal combustion engine 37: speed ramp-up (transient) without load with current measurement -Test programs for checking the control program (I / O check and actuator check) -Weight measurement and photo recording -Scanning Data Matrix codes etc. -Special measurements for vibration and noise emissions and particle counters - Validation checklists, e.g. for visual inspection and testing procedures -Inspection indication (good / bad, rework).

[0043] A universal diagnostic device 38, which is shown diagrammatically in FIG. 5, is configured for checking all modules 11-22. In the setup station, there is a loading zone, a mobile transport device with module mountings, a lifting device and an assembly tool. The diagnostic device 38 itself is a universal measuring and inspection device with mechanical mounting elements adapted to the mechanical interfaces of the modules 11-22, a specific energy supply, universal interfaces for electrical systems, hydraulic systems, fuels, additives, water, air and oil, measuring instruments for the detection of all electrical measured quantities, a control device 24 for the generation and processing of all control signals, various media (e.g. Coriolis sensors from Danfoss), sensors for time measurement, image detection and force measurement, a scanner for data matrix (lot and date), traceability components (linking part numbers with dates, lots and evaluations) and components for the calibration of the measuring technology. The interfaces 23 of the diagnostic device 38, which are shown diagrammatically in FIG. 5, are adapted to all predefined interfaces 23 of the modules 11-22 to be tested.

[0044] Advantageously, the diagnostic device 38 has an ERP interface for data detection, conversion in a formatted database, assignment of measurement data to part numbers, lot, date and order numbers, data archiving in the database, printing out inspection certificates if required, statistical evaluation and general evaluation (good / bad).

[0045] The rework station includes a set of assembly tools, a work bench, a medium tank, and equipment for evaluating and removing errors, after which the product is returned to the measuring station for further checks using the diagnostic device 38.

[0046] All checked and passed modules 11-22 are joined and screwed step by step in a final assembly sequence. As in the case of interlocking brick building blocks, all functional modules 11-22 are stacked on top of each other and coupled to each other and / or to the vehicle frame 1. This joining process is preferably performed from the top down. Alternatively, a joining process from the bottom up would also be possible. Depending on the module arrangement, the mounting sequence and the setting of the mounting positions, the vehicle 2 can be assembled on the track 39 by means of a mobile crane in a short time.

[0047] After the modules are inserted and tested, the system functions are tested and certified. In this way, the main functions are activated and the reactions are measured, either manually or in an automated process. This allows simple I / O processes as well as complex system functions to be tested and certified. The usage limits are defined and pass / fail assessments can be standardized and automated.

[0048] The common parts concept will be described with reference to FIG. 7. The same vehicle frame 1 forms the base for all modules 11-22. The vehicles 2 shown differ in terms of structure in that the structural modules 12-22 are selected differently. For example, the top vehicle comprises a travel cabin module 21, a welfare cabin module 18, a workshop module 17 with a platform, a technical room module 19 and another travel cabin module 21. In the case of the middle vehicle 2, a workshop module 17 with a luggage compartment is combined. The lower vehicle 2 comprises a loading surface module 20 instead of the welfare cabin 18. In the control device 24, control software is provided for controlling the operation of the modules 11-22. In this case, one software module 40 is assigned to each selectable functional module 11-22. These software modules 40 are de-restricted according to the functional modules 11-22 to be constructed in the respective vehicle 2.

[0049] 8 shows the fully assembled work vehicle 1 on a track 39, which comprises as above-floor modules the crane module 12, the travelling cabin / crane cabin 21, the welfare / workshop modules 17, 18, the lifting platform module 13, the overhead line and energy supply module 16 and the further travelling cabin 21. On the roof further modules 22 (e.g. various work aggregates) are mounted. As under-floor modules there are arranged a traction module (power pack) 14, a tank module 15 for fuel, a tank module 15 for hydraulic oil and various further modules 22 (e.g. a transformer module, a cooling system module, a braking resistor module, a battery module with a battery thermal management system).

[0050] Two alternative traction modules 14 are shown in figures 9 and 10. The conceptual structure is divided into a fixed area, a modular area 35 and an expandable area 36. The fixed area houses, for example, the internal combustion engine 37, the coolant cooler 41, the charge air cooler 42, the exhaust system 43 and the urea solution tank.

[0051] In the modular area, different components are arranged so that the traction module 14 can be used, for example, as a diesel-electric, hydrostatic or hydrodynamic energy source. In the diesel-electric configuration shown in FIG. 9, the internal combustion engine 37 is connected to a generator 44 and a hydraulic pump 45. In the hydrostatic configuration shown in FIG. 10, the internal combustion engine 37 is connected to a pump distributor gearbox 46. In the expandable area 36, ​​for example, an exhaust flap 47 is present.

[0052] For the connection of the individual components a carrying frame 48 with connection mounts is used as predefined mechanical interface 23. If necessary the carrying frame 48 is attached to the vehicle frame 1 by means of the auxiliary frame 25. For service work the entire unit can be easily dismantled. The described concept can also be transferred to other modules, e.g. an accumulator module, a hydraulic module, a fuel tank module, a transformer module or a cooling plant module.
