Description

The present invention relates to a carrier of a track for a track-bound vehicle, in particular a magnetic levitation, wherein the carrier has a laterally projecting from the carrier concrete plate and at the two lateral ends of the plate at the bottom of the plate stators, on the side surfaces of the plate side guide rails and at the top of the plate sliding strips for driving and guiding the vehicle are arranged.

From the DE 37 16 260 C1 a method for adjusting and fixing functional surfaces of a travel path of an electromagnetic high-speed railway is known. Here, side guide rails are brought into a required position after the adjustment and attachment of stators, positioned opposite the track carrier and then attached to the track carrier. The side guide rails are fastened at their ends to anchoring bodies of steel embedded in advance in the guideway carrier by welding or connected to the guideway carrier via anchoring bolts by casting with hardening material. The slide strips, which consist of a greatly inflated bump on the top of the carrier are milled to the required degree and ground. A disadvantage of this design is that very expensive devices are required for positioning the side guide rails and for editing the wear strips. In addition, the devices must position the side guide rails until the hardening material has cured and the side guide rails are fixed. The production of such a guideway is therefore very time-consuming and thus costly.

The object of the present invention is to provide a carrier which can be produced particularly quickly and inexpensively and provided with functional surfaces.

The object is achieved with a carrier of a track for a track-bound vehicle with the features of claim 1.

According to the invention, the carrier of a guideway for a track-bound vehicle, in particular a magnetic levitation train, has a concrete plate projecting laterally from the carrier. At the two lateral ends of the plate stators are arranged on the underside of the plate, on the side surfaces of the plate side guide rails and at the top of the plate sliding strips for driving and guiding the vehicle. On the support are hardenable, in particular concreted contact surfaces for the side guide rails and / or for the stators and / or for the sliding strips. The side guide rails and / or the stators and / or the slide strips are preferably screwed to the bearing surfaces provided for this purpose.

The contact surfaces are produced together with the carrier. This means that they are preferably created simultaneously with or after the production of the carrier. It is important that only after the completion of the contact surfaces, the attachments are screwed to the contact surfaces.

In contrast to the prior art bearing surfaces are provided which are integrated in the carrier. A positioning of the attachments during the casting of the attachments with the carrier is not required by this. After a correct position production of the contact surfaces, which depends on the requirements of the maglev and the route in which the carrier is to be integrated, the add-on side guide rail, stator and / or slide bar can be arranged directly, in particular screwed. It is thus a fast, inexpensive and simple Assembly possible. The attachments consist of very simple components, which in turn can be made extremely inexpensive. Also, the disassembly of the attachments, such as for repair or replacement of damaged attachments is quick and easy to perform because the attachments are detachably mounted on the contact surfaces and thus can be replaced quickly. The side guide rails, stators or slide strips are preferably designed independently of each other, so that they can be mounted and dismounted individually. The contact surface according to the invention need not be provided for all attachments. It is sufficient if, for example, only the side guide rails or the stators are screwed to the bearing surfaces provided for this purpose. The contact surfaces themselves can already take over the guiding function of the vehicle. So it may be sufficient in particular for the sliding strips, if they consist of the contact surfaces themselves. A separate component of the wear strips is therefore not required.

It is particularly advantageous if the carrier is a precast concrete part. In this case, not the complete support must be designed as precast concrete. It may also be a combined construction in which, for example, the plate is a precast concrete part and the base of the support is made of steel.

If the contact surfaces are largely in the correct position, in particular concreted in accordance with predetermined variants of the carrier, then no or only a small amount of machining of the contact surfaces is required prior to mounting the attachments. Variants of the carrier, for example for installation in a curve or in straight lines of the route, can therefore be provided in principle during the production of the carrier.

It when the carrier is formed so that one of the contact surfaces forms a concrete sliding strip is particularly advantageous. The assembly of a separate Attachment for the slide bar is not required by this. Due to the precisely formed, extending along the support bearing surface, this can serve directly as Absetzfläche for the vehicle. The strength of the concrete is sufficient, so that a dedicated steel strip is not required.

In order to avoid damage to the vehicle or the carrier when depositing the vehicle on the sliding strip, it can be provided in a preferred embodiment of the invention that the concrete sliding strip is coated. As coating materials, for example, plastics can be provided, which are applied to the concrete slide strip.

Advantageously, the concrete sliding strip and / or the contact surfaces are processed after a storage period of the concrete slab. As a result, unavoidable dimensional changes during the setting time of the concrete support are awaited in order to then create a permanent positionally correct contact surface or concreted sliding strip. If the processing took place too early, a contact surface which had originally been precisely machined would, within a few days together with the concrete support, be changed with regard to their dimensions in such a way that the permissible dimensional tolerances for the contact surface would be exceeded.

The hardenable contact surfaces are advantageously mechanically processed, in particular milled and / or ground. As a result, accuracies are achieved, which meet the extremely high requirements of a maglev train and ensure the driving of the vehicle. For fastening the side guide rail clamping means, in particular at least one tensioning wire or a tie rod is provided, with which the side guide rails are connected to the carrier. An accurate and largely immutable attachment of the side guide rail on the carrier is hereby guaranteed.

In order to connect the side guide rails and / or the stators and / or the slide strips with the carrier, it is provided in a particularly advantageous manner that in the region of the trained bearing surfaces fastening means, in particular threaded sleeves and / or sleeve-nut inserts are integrated into the carrier. The attachment means may be embedded in the support during manufacture of the support or panel. If necessary, the end faces of the threaded sleeves and / or sleeve-nut inserts are machined together with the contact surfaces, so that a positionally accurate contact surface for the attachments is formed. About screws and the integrated fasteners then the side guide rails, stators and / or wear strips are screwed to the carrier. In order to obtain the required degree of attachments to each other for error-free driving and driving of the magnetic levitation vehicle, it is understood that both the side guide rails and the stators and possibly the slide strips were also made to an exact size in order to work in conjunction with the correct contact surfaces To obtain prescribed pliers measure between the individual attachments. Due to the simple design of the attachments, which is made possible by the integrated contact surfaces in the support, adherence to small dimensional tolerances of the attachments is very easy to obtain.

For example, to avoid a mechanical processing or to make only a very small extent required, it is particularly advantageous if the hardenable contact surfaces are already formed by correcting the manufacturing form when concreting the plate in the correct position or largely correct position. In this case, the formwork is made variable and adjustable in the area of the contact surfaces in order to adapt the contact surfaces to the requirements placed on the carrier for installation in the route. For example, in the case of a distortion of the carrier, the course of the contact surfaces may deviate from the course of the carrier in order to ensure proper guidance of the vehicle.

Depending on the requirement, it is advantageous if the hardenable contact surfaces are formed either continuously or discontinuously along the plate. A continuous design of the contact surfaces is particularly suitable for the wear strips and the stators. Particularly advantageous is the discontinuous design of the contact surfaces for the side guide rails. The particular advantage of this is that rain or melt water, which collects on the top of the carrier, between the carrier and the side guide rail by the distance that arises between the curable contact surfaces, can flow. A separate device for discharging the rain or melt water from the top of the carrier is thereby no longer required. In addition, the side guide rails are largely kept free of water, which in particular in winter icing of the side guide rails and thus a significant change in the dimension and, associated with a disturbance of the driving operation of the vehicle is reliably prevented.

In order to obtain a particularly good guidance of the stators, it is advantageous if the hardenable abutment surfaces one side of the plate bitden each two mutually parallel hump. On the humps, the stators and the holders of the stators are arranged. For this purpose, in turn, in particular screwing on, since this can be carried out quickly and in particular an exchange in defective stators or Statorenhaltem is advantageous.

New and inventive is when the plate between the two parallel sliding strips opposite the slide strips is formed increased. While it has hitherto been customary to form the sliding strips as a bump on the upper side of the plate, a step-like or outwardly sloping course of the upper side of the plate is now provided, wherein the sliding strips are arranged lower than the surface of the plate between the two sliding strips of the plate. This ensures that rain and melt water, which is on the top of the carrier or the plate collects, can drain to the lateral outer sides of the plate. A jam between the two humps of the sliding strips of the prior art is thus no longer. A separate means for discharging the rainwater and melting water is thereby no longer necessary, whereby the construction of the carrier is again significantly cheaper to carry out.

Of course, particularly advantageous is when the top of the plate is stepped or sloping starting from its longitudinal axis on the slide strips to the side guide rails. Thus, even with a continuous attachment of the side guide rail can be ensured that the water flows from the top of the plate, if necessary, also on the side guide rails. It also ensures that no congestion between the side guide rails and the sliding strips, which in turn would be a disturbance of driving, especially in heavy rain events or icing of the carrier would be feared.

Further advantages of the invention are described in the following exemplary embodiments. It shows

FIG. 1 shows a support 1, which consists essentially of a plate 2 and webs 3, wherein only one half of the carrier 1 and thus only one web 3 is shown for clarity. The carrier 1 is designed as a precast concrete element and is manufactured in the illustrated form in a precast concrete factory and then to a route of a travel path transported for a track-bound vehicle, in particular magnetic levitation railway.

The plate 2 protrudes in the form of a cantilever over the web 3 addition. The lateral end of the plate 2 is provided for guiding or for the cultivation of guiding and driving parts of the vehicle. The attachments, which are required for guiding and driving the magnetic levitation vehicle, consist at the top of the carrier 1 of at least one, usually two slide strips for depositing the vehicle, at each lateral end of the plate 2 each have a side guide rail for laterally guiding the vehicle as well the underside of the plate 2 of stators and their suspension for driving the vehicle.

In the present invention, the plate 2 is provided with abutment surfaces 5, 6 and 7. Contact surface 5 is designed in the present embodiment in such a way that it itself already serves as a sliding strip. The surface of the slide strip 5 is ground so that it already complies with the predetermined dimension of the sliding strip. In addition, the contact surface 5 is formed continuously, whereby a magnetic levitation vehicle when settling on the contact surface 5 can slide to a stop. The contact surface 5 is furthermore arranged in a stepped manner in comparison with the surface of the plate 2 arranged in the region of a center line 10 of the carrier 1. Towards the end of the plate 2, a further step is provided. As a result, rain or melt water, which collects on the top of the plate 2, discharged to the edge of the cantilever and can flow there. An additional drainage system on the plate 2 for water is not required by this. Of course, the step does not have to be as pronounced as in FIG. 1 shown. It can also be continuous or curved. It is essential, however, that a drainage of the surface water from the carrier 1, without that a greater amount of water accumulates on the surface of the carrier 1, is ensured.

The abutment surfaces 6 are arranged discontinuously on the outer lateral end faces of the plate 2. In the area of the contact surfaces 6 threaded sleeves 11 are embedded in the concrete of the plate 2. At the threaded sleeves 11, a side guide rail is screwed after machining the contact surface 6.

The machining of the contact surfaces 6 takes place as well as in the contact surfaces 5 and 7 by milling and / or grinding. As a result, very precise surfaces and low tolerances are possible. A dimensionally accurate side guide rail, which is screwed to the contact surfaces 6, thus allows an exact assignment to later-described stators and side guide rails, which are arranged on the opposite side of the plate 2. The resulting Zangenmaß is decisive for a reliable and accurate guidance of the vehicle on the support. 1

At the bottom of the cantilever of the plate 2, the other contact surfaces 7 are provided. The contact surfaces 7, which as well as the contact surface 5 run continuously along the carrier 1, serve for fastening the stators. Also in the contact surfaces 7 threaded sleeves 18 may be embedded, to which the stators and their support are screwed. The interface of the contact surfaces 7 to the supports of the stators are also milled and / or ground in order to obtain an exact measure, which must be complied with in particular with respect to the contact surface 5.

On the contact surface 5, if the contact surface 5 itself is not to be used as a sliding strip, a further strip, for example, also be fastened to the contact surface 5 via dowel and screw connections. Advantageously, also in this case, the slide bar and the contact surface 5 is formed such that it is arranged lower than the central surface of the plate 2 and formed elevated relative to the lateral edge is to allow the outflow of water to the lateral edge of the plate 2 out.

In FIG. 2 is a perspective view from below of a support 1 shown. The carrier 1 substantially corresponds to the carrier 1 FIG. 1 , From this representation, in particular the continuous arrangement of the contact surfaces 7 becomes clear. However, the invention is not limited to the continuous arrangement of the contact surfaces 7. It can also be carried out discontinuously, this bearing surface 7 by only a corresponding contact surface 7 is provided at the locations where the stators or the stator suspensions are to be attached. The advantage of the discontinuous contact surface 7 is that less material processing is required in order to arrange the stators in the correct position. The processing is thereby less expensive and thus cheaper.

To attach the stators sleeve nut inserts 18 are embedded in the area of the contact surfaces 7. To the sleeve-nut inserts 18, the stature suspensions are screwed.

The contact surfaces 6 are in turn formed discontinuously on the outer end faces of the plate 2. This results in the cultivation of side guide rails spaces between the side guide rail and the plate 2 between the individual contact surfaces 6. These spaces are suitable for the flow of collected on the surface of the plate 2 water without the water must flow over the side guide rails away. This is particularly advantageous in winter, since this avoids that the side guide rails freeze and thus could restrict the driving of the vehicle.

FIG. 3 shows a detailed view of a cantilever of a plate 2. On the contact surface 6 is a side guide rail 12 via a screw 13 with the threaded sleeve 11 connected. The side guide rail 12 is pressed by the screw 13 to the machined surface of the contact surface 6. The threaded sleeve 11 is cast in the concrete of the plate 2. It is firmly anchored in the plate 2 via a tension rod 14. The not shown end of the tension rod 14 opens, for example, in a further threaded sleeve, not shown, which serves for fastening the opposite side guide rail 12.

At the bottom of the cantilever of the plate 2, a stator 15 is fixed to drive the vehicle. The stator 15 is arranged in the present embodiment of a stator 16 which is connected to the stator 15 according to the principle of a tongue and groove connection. The Statoraufhängung 16 is screwed by means of screws 17 in the cast in the concrete of the plate 2 sleeve nut insert 18. The stator suspension 16 is pressed against the machined surfaces of the contact surfaces 7 and thereby brings the stator 15 in the predetermined position. Of course, other forms of Statoraufhängung 16 are possible, which do not fix the stator 15 in the form of a tongue and groove connection, but for example fix the stator 15 with screws, bolts or sleeves.

Are the sleeves of the sleeve-nut inserts 18 slightly conical to the mother formed, so on the one hand the insertion of the screw 17 in the sleeve-nut insert 18 is facilitated and on the other hand, an angular offset between the sleeve axis and the screw axis of several degrees for the Mounting of stators 15 allows. An adaptation of the stators 15 to the desired position can thereby be realized very easily. The anchoring of the sleeve nut insert 18 in the concrete by means of a large disc in the mother.

The top of the plate 2 is in turn stepped. The steps cause that from the center of the plate 2 towards the lateral edge of the plate 2, this is stepped down. As a result, the water, which on the Surface of the plate 2 is collected, led to the side of the plate 2. The gradation is also provided in the contact surface 6 by means of a slope, which is continued towards the also lowered side guide rail 12. In addition to the gradation shown here, of course, another shape of the slope can be generated, for example with a slightly curved surface of the plate 2 or with an inclined plane of the surface of the plate 2, in which the contact surface 5 and the sliding strip formed therefrom as a horizontal plane Surface is ground.

In FIG. 4 is a cross section through a tilted support 1 is shown. The inclination, ie a horizontal inclination of a few degrees, causes water to drain from the surface of the carrier 1. In order to avoid accumulation of water on the support 1, the elevations for the formation of the contact surfaces 5 are formed such that in the direction of the lowered end of the support 1 no or little increases, but essentially only gradations are provided. Reliable driving is thus guaranteed even in heavy rainfall events.

The present invention is limited to the appended claims and the illustrated embodiments. In particular, combinations of the individual elements of the invention are of course possible. Thus, according to the inventive principle, only the side guide rail can be arranged, while the attachment of the slide bar or the stator suspension takes place according to another principle.
