Description

Field of application of the invention

The invention relates to a supporting structure for the track of a track-bound vehicle, in particular a maglev train, with a carrier, at least one piece of equipment and a device for precise mounting of the equipment on the carrier, the equipment is provided with a corresponding to the route running surface and the device on Carrier-mounted terminal body with holes formed on the terminal bodies, arranged according to the course of the functional surface first stop surfaces formed on the equipment part, cooperating with the first stop surfaces second stop surfaces and inserted into the holes fastening screws for attachment of the equipment to the terminal bodies. Moreover, the invention relates to a method for producing such supporting structures.

Characteristic of the known state of the art

Concrete or steel tracks for track-bound vehicles consist of a multitude of supporting structures consecutive along the route, on which are mounted all the equipment required for the operation of the vehicles, in particular their carrying, driving, driving, braking, etc. In magnetic levitation railroads, for example, each support structure has a rigid support on which functional surfaces having equipment parts in the form of side guide rails, reaction rails of a long-stator motor or the like. Are attached. The carriers are stored on supports anchored in foundations, measured by conventional geodetic methods and then fixed, while the equipment is attached to the carriers that their functional surfaces are after fixing the carrier to the supports exactly on the prescribed by the path paths ,

In order to operate at very high speeds, e.g. 500km / h to enable a vibration-free driving and especially to avoid striking the vehicles to the functional surfaces, the actual coordinates of the individual points of the functional surfaces may at most by a few millimeters of the respective target values, ie their on the theoretical route related X, Y and Z coordinates deviate. Because of the usual in concrete and steel manufacturing tolerances, but this accuracy can not be readily obtained. Therefore, the supporting structures were first designed so that the exact position of the equipment on the carriers in a particular Justierschritt and after fixing the support on the supports had to be made (ZEV Glass, Ann. 105, 1981, No. 7/8, pages 205-215). This made it possible to allow the usual manufacturing tolerances and to subsequently eliminate the resulting deviations between the nominal and actual values of the functional surfaces by adjustment.

Since such an adjustment is complicated, requires a lot of time, must be done at the respective site and can not be carried out in all weathers, a support structure of the type described has already become known (US-PS 4,698,895), in their application account for the adjustment can. This support structure is characterized in that the terminal body provided with countersinks (blind holes) and tapped holes and the equipment with the aid of used in the lowering spacers positioned relative to the carriers and then secured by means of introduced into the threaded holes mounting screws to the carriers. The subsidence and tapped holes in each support structure, taking into account their bearing points on the supports and the other Trassierungsvorschriften (target coordinates of the functional surfaces, associated track section or the like.) Drilled so that when using the same length spacers and identical equipment parts regardless the correct position for the functional surfaces is obtained as to whether the equipment is attached to the support structure before or after assembly. This results in particular the advantages that all necessary for the route fitting installation of the equipment on the supporting structure work can be performed in a factory hall and for securing and securing the equipment items only inexpensive spacers and mounting screws are needed. However, the known support structure makes it necessary to bring the equipment parallel to the axes of the counterbores and tapped holes to the connector body. This is not always possible or at least associated with difficulties, in particular if, in addition to the creation of a redundant and diverse fastening system, positive-locking connecting elements are provided which are joined perpendicular to the axes of the countersinkings or threaded bores (see patent application P ... of the same Applicant of same day) and to prevent the equipment from falling even if the fastener screws fail. Apart from that, the Distanhülsen represent additional mounting parts, which increase the manufacturing and assembly costs of the entire infrastructure. Finally, the achievable by the known fastening dynamic behavior is not optimal, because the equipment can only be attached via spacers and not directly to the carriers.

Object of the invention

The aim of the invention is to improve the support structure of the type described above in that the equipment mounted with the omission of the spacers directly to the terminal body and can also be moved transversely to the threaded holes for the mounting screws during assembly without thereby on the principle advantages in terms of compliance with the routing requirements must be waived. In addition, a method for producing such supporting structures is to be specified.

Essence of the invention

The technical object of the invention is to achieve the desired goal by a new design of the connector body.

To solve this problem, the support structure according to the invention is characterized in that the first stop surfaces are formed in the direction of the equipment above projections of the terminal body and abut the second abutment surfaces on the first stop surfaces.

The method for producing such a support structure, in which in a first process stage, the carrier with the usual tolerances in steel and concrete and the equipment with the tolerances required by the Trassierungsbestimmungen and in a subsequent process step downstream of the holes in the connecting bodies with the According to the invention, the tolerances required by the dimensioning provisions are produced by providing the support during the first process stage with connecting bodies having the projections, the projections being longer than the largest length required within the travel, and the first abutment surfaces being in the downstream operation with the required by the routing requirements tolerances are formed by machining the approaches.

Since the first abutment surfaces are formed on projecting lugs of the terminal bodies and no additional spacers or the like are provided more, the equipment can be easily positioned by displacements transverse to the axes of the threaded holes for the mounting screws. Nevertheless, the advantage remains that the first stop surfaces and the threaded holes can be made using a computer-controlled, cutting tool and thus taking into account all Trassierungsvorschriften and therefore the functional surfaces are automatically arranged according to the route after tightening the mounting screws.

In a preferred embodiment of the support structure according to the invention, the second stop surfaces are formed on fixedly connected to the equipment trusses.

In support structures made of steel, the connecting body preferably made of the carrier fixed web plates, while in supporting structures made of concrete, the connecting body preferably connected to the reinforcement and are cast into the carrier.

The lugs can be formed by attached to the terminal bodies round rods.

To create a diverse fastening system, the device expediently additionally positively acting fastening elements, which can have at least one each corresponding to the course of the functional surface recesses arranged on each terminal body and an associated, attached to the equipment fuse element.

In this case, the securing element is preferably attached to the cross member.

In a further development of the method according to the invention, the first stop surfaces are advantageously produced by milling.

In a particularly preferred embodiment of the method according to the invention also provided on the terminal bodies recesses are formed in the downstream operation with the required by the Trassierungsvorschriften tolerances by machining. The recesses are conveniently prepared by drilling.

Support structure and Fig. 12 and 13: each have a transverse and longitudinal section through a support structure according to the invention in concrete construction.

The support structure according to the invention is described below using the example of a magnetic levitation railway, which is driven by a long-stator motor. It is understood that the support structure with appropriate modifications can be adapted to other track-bound transport systems.

In a magnetic levitation train with synchronous long stator motor (Fig. 1) of the infrastructure is composed of a plurality of supporting structures, which are arranged one behind the other in the longitudinal direction of the route and a length of z. B. have about 24m. Each support structure includes at least one, laterally projecting support 1 and is mounted on anchored in foundations, not shown supports. Each carrier 1 typically includes a plurality of pieces of equipment 2, e.g. consist of grooved laminations of the long stator motor and e.g. have a length of 2m. In the grooves of the equipment 2 windings 3 are inserted, which are fed with three-phase variable amplitude and frequency. The exciting field of the long stator motor is generated by supporting magnets 4, which are connected to a moving along the route, in Fig. 1 only schematically indicated vehicle 5 and each consist of a magnetic core 6 and a field winding 7. In addition to the function of the magnetic carrying the supporting magnets 4 at the same time the exciter field of

Long-stator engine ready. In general, the equipment parts 2 are provided on both sides of the support structure mounted carriers 1 and the supporting magnets 4 on both sides of the vehicle 5.

The undersides of all equipment 2 form functional surfaces 8, to which the pole surfaces of the magnetic cores 6 with a floating and moving vehicle 5 a fixed predetermined distance 9 of e.g. 10 mm. Compliance with this distance is ensured by appropriate control systems. Therefore, the functional surfaces 8 must be arranged with small tolerances parallel to the route and adjoin one another at the joints between the individual pieces of equipment 2 with a small offset.

Support structures of this type are well known (US-PS 4698895) and therefore need not be explained in more detail. According to the invention shown in Fig. 2 to 6 and manufactured in steel construction carrier 1 are provided on its underside with spaced in the longitudinal direction of the route connecting bodies 11 in the form of transverse to the track arranged web plates on which the equipment parts 2 are fixed with mounting screws 12. The connector body 11 are provided with in the direction of the equipment 2, here so with downwardly projecting or protruding from the actual support 1 and perpendicular to the direction of the trench direction approaches 14 whose free end faces first stop surfaces 15 (Figures 2 and 6). In this case, the lugs 14 and the adjoining parts of the connecting body 11 each have a bore 16 (FIG. 5) for receiving one of the fastening screws 12. The bore 16 is preferably a threaded bore into which the fastening screws are screwed without the use of nuts.

The equipment parts 2 are on their the terminal bodies 11 facing sides, here on their tops, provided with trusses 17, the top second stop surfaces 18 (Fig. 2 and 6) form or have and run exactly parallel to the functional surface 8 of the respective piece of equipment 2. The trusses 17 are preferably fixedly connected to the equipment parts 2, for example by means of positive tongue / groove connections and additional adhesion, and the abutment surfaces 18 preferably all have the same distance from the functional surfaces 8. The spacings of the trusses 17 in the longitudinal direction of the route correspond to the distances between the connecting bodies 11 and the lugs 14. At their lateral ends projecting beyond the equipment parts 2, the trusses 17 each have bores 19 (FIG. 2) for receiving the fastening screws 12. Preferably, the arrangement is such that each piece of equipment 2 corresponding to FIG. 2, two trusses 17 and 17 each traverse 17 has two holes 19, wherein the spacing of the holes 19 each traverse 17 corresponds to the distance of the holes 16 of the connector body 11. Therefore, each piece of equipment according to FIG. 2 is fastened to the associated carrier 1 with the aid of four fastening screws 12.

For mounting the equipment 2, the stop surfaces 15 and 18 are placed against each other, aligned the holes 19 on the holes 16 and then screwed the mounting screws 12 until their heads firmly against the undersides of the trusses 17. The approach of the piece of equipment 2 to the lugs 14 can be done practically from any side.

So that the functional surfaces 8 of all equipment 2 any support structure after assembly to the permissible deviations are automatically parallel to that section of the route to which this support structure is assigned, all equipment parts 2 are identical, the first stop surfaces 15 and the holes 16, however, designed to fit , This is understood in the embodiment that all abutment surfaces 15 of any support structure are arranged on a surface that has the same course as the support section associated with this route section. Therefore, after the attachment of all equipment 2 on this support structure and the area formed by the associated functional surfaces 8 has a course corresponding to the associated route section. Finally, the relative position of the lugs 14 on each support structure is chosen so that with proper stringing of all supporting structures along the track and after the specified fixation of the carrier 1 on the supports, the functional surfaces 8 of all equipment 2 are on the prescribed by the routing area and At the joints of the individual pieces of equipment or the supporting structure does not exceed the permissible values going beyond offset of the functional surfaces in any direction. Here, the height offset should be negligible, while the lateral offset can usually be a few millimeters.

In fact, the functional surfaces 8 of the individual pieces of equipment 2 and thus also the associated abutment surfaces 15 and 18 are preferably in planes, so that the entire functional surface of each support structure are formed according to Arte a polygon of a plurality of flat functional surfaces 8. However, the resulting deviations of the actual values from the target values are tolerable in the face of the large radii of curvature of the usual routes. The belonging to any piece of equipment 2 stop surfaces 15 may be in the rest in the same plane, but also in different levels. In the latter case, the stop surfaces 18 would have to be arranged in correspondingly different planes. The production of the first stop surfaces 15, which are effective as reference surfaces for the position of the functional surfaces, preferably takes place in that the carrier 1 is provided with the connecting bodies during the production process and they already have the lugs 14. In this case, the lugs 14 is given a length which is slightly larger than the longest required within the entire infrastructure approach 14 corresponds. Thereafter, the lugs 14 are preferably processed analogously to known methods (US-PS 4698895) in a downstream of the manufacturing process of the support structure operation by means of computer-controlled tools. This has the advantage that the known method and the devices required for its implementation need only be modified to the effect that an additional tool in the form of an end mill or the like. Provided with each approach 14 by machining on the for him shortened required length and the resulting stop surface 15 can be given at the same time required for them angular position with respect to a fixed spatial reference plane. By using a combined countersink / face milling tool or the like. In this operation at the same time the holes 16 are formed, the axes of which are preferably perpendicular to the stop surfaces 15 and which can then be transformed with a tap into threaded holes. These operations, which can be carried out successively or at least partly simultaneously, are preferably carried out in an air-conditioned factory under controlled conditions and with the consideration of all parameters important for the routing (US Pat. No. 4,698,895). The attachment of the equipment 2, however, can optionally also be done in a factory or at the construction site, possibly even after the installation of the carrier 1, as an adjustment is not required.

When using four fixing screws 12 for each piece of equipment 2, the entire fastening device is redundant. Failure of any mounting screw 12 is still no malfunction. The same applies if on each of the two trusses 17 a fixing screw 12 fails. Fail against both fastening screws 12 at the same end of a cross member 17, then the piece of equipment 2 fall at this point due to its considerable weight by itself or moved due to the forces occurring when driving on the road in the direction of action of these forces, with the risk that the break or bend two other fastening screws 12. In any case, a malfunction occurs in the region of the joint to the neighboring piece of equipment 2 in the form of a possibly significant height offset between the adjacent functional surfaces 8.

To avoid this non-excludable malfunction, a development of the invention according to Figure 7 to 11 provides a fastening device that is redundant and diverse and in addition to the embodiment of FIG. 2 to 6 has a device that the fall of the equipment even when all Fixing screws 12 limited to a preselected value. This device preferably has a form-fitting acting, unloaded in normal operation fasteners that are effective only at failure of the mounting screws. The embodiment of FIGS. 7 to 11, in which the same reference numerals are used for the same parts, corresponds with respect to the positioning of the equipment 2 on the supports 1 of the embodiment of FIGS. 2 to 6 except for the fact that the lugs and first abutment surfaces not are formed directly on the connector body. Instead, connecting bodies 21 are provided with bores 22 in which round bars 23, e.g. are fixed by welding. The free, protruding from the bores 22 ends of the round rods 23 form on the terminal body 21 projecting lugs 24 (Fig. 7 and 11), whose end surfaces are the first stop surfaces 25 (Fig. 11). For the lugs 24 and abutment surfaces 25 the same applies as for the lugs 14 and abutment surfaces 15 so that so far only the production of the carrier 1 during the first process stage is a slightly different. In addition, the terminal body 21 still two recesses 26 with parallel to the stop surfaces 25 extending axes and holes 27 which are formed in the embodiment in the round rods 23, perpendicular to the stop surfaces 25 extending axes and preferably consist of threaded holes.

The equipment parts 2 are provided with trusses 28 which have second abutment surfaces 29 (FIG. 11) and, to that extent, correspond to the trusses 17. In addition, however, the trusses 28 are provided with integrally formed or otherwise attached webs 30 (FIG. 11), which are arranged perpendicular to the abutment surfaces 29 and extend in the direction of the connecting bodies 21. At these webs 30 are bolt-shaped security elements 31 z. B. by welding, whose axes are parallel to the stop surfaces 28. The distance between the securing elements 31 corresponds to the spacing of the recesses 26. Its position in the connecting bodies 21 is selected such that the securing elements 31 are inserted into the recesses 26 parallel to the abutment surfaces 25, 29 during assembly of the equipment parts 2, then the abutment surfaces 25, 29 brought to the plant and finally the fastening screws 12 can be inserted into the holes 27 and tightened.

The cross-sections of the recesses 26 are preferably slightly larger than the outer cross-sections of the securing elements 31. This simplifies the one hand, the assembly of the equipment 2 and on the other hand allows for breakage of both mounting screws 12 a traverse 28 lowering or offset of the associated equipment part 2 by a defined value of z. B. maximum 2 mm to 3 mm. As a result, in the region of the joint to the adjacent piece of equipment, a corresponding height offset occurs between the adjacent functional surfaces 8, which is visible from the outside. Therefore, double screw breaks can be detected by driving off the route by means of a Meßzuges or the like. And repaired immediately. Alternatively, it is possible to equip each vehicle with a distance sensor or the like responsive to a height offset at the joints of adjacent pieces of equipment 2, so that each vehicle can automatically check the route for any errors.

The production of the securing elements 31 is expediently such that they lie at identical parts in all pieces of equipment 2 and have the same shape and size. In contrast, the recesses 26 by means of a computer-controlled tool, for. As a drilling tool, during the production of the holes 27 and the stop surfaces 25stassen attached. This means that the axes of the recesses 26 are formed parallel and at such distances to the first stop surfaces 25, as corresponds to the distances of the axes of the securing elements 31 from the second stop surfaces 29. This can be done in a simple manner in that the device known per se (US-PS 4698895) is provided with a further tool and in the production of the recesses 26 of any terminal body 21 during the subsequent operation, the coordinates required for controlling the tool on the abutment surfaces 25 of the same terminal body 21 are related.

Constructed in concrete construction, a slack reinforcement 34 having carrier 35 may on its underside, as shown in FIGS. 12 and 13, also provided with spaced in the longitudinal direction of the route, preferably made of steel connecting bodies 36 in the form of transverse to the track arranged web plates. The terminal bodies 36 have at the one ends of central portions 37 preferably flange mounting plates 38 and at the other ends of the central portions 37 of the lugs 14 and 24 corresponding to the first stop surfaces forming lugs 39 on which the equipment parts 2 are fastened by means of screws 12. In contrast to the steel structures according to FIGS. 1 to 11, the mounting plates 38 are cast into the concrete during the production of the supports 35 and, as indicated by the reference numeral 40 in FIGS. 12 and 13, preferably fixedly connected to the reinforcement 34. Moreover, the arrangement according to FIG. 1 to 11 may be taken.

As can be seen in particular from Fig. 12, the mounting plates 38 are preferably poured into the concrete so that their undersides flush with the underside of the carrier 35. In this case, the middle portions 37 can be kept very short or completely absent and the lugs 39 can be formed directly on the mounting plates 38. This results in a mechanically very stable and compact design. If necessary, the support 35 may be provided in the region of the lugs 39 with recesses which facilitate the attachment of the tools 39 required for machining the lugs 39.

The invention is not limited to the described embodiments, which can be modified in many ways. For example, it is not necessary to form the bores 16, 27 for the fastening screws 12 in the lugs 14 or round rods 23. Rather, it would also be possible to attach them to other areas of the connection body 11, 21 and equipment 2 lying outside the abutment surfaces 15, 25. Furthermore, it is possible to provide more or less than four fastening screws 12 or more than two crossbars 17, 28 for fastening a piece of equipment 2. The number of equipment provided per carrier 2 is basically arbitrary. In addition, besides the illustrated pieces of equipment 2, other pieces of equipment, e.g. 3 and 8 apparent side guide rails 32 are mounted by means of the described fastening device, in which case the positive engagement of the form-fitting fastening elements preferably again in those directions is effective in which act the forces occurring during normal operation. Furthermore, the shape and the position of the abutment surfaces 15,18 and 25, 29 are largely freely selectable, if it is ensured that they and not other parts determine the final position of the equipment 2 on the carriers 1.35.
