Definitions
- the present invention relates to a system for producing guideway elements.
- Travel routes in particular rail travel routes and in particular rail travel routes for magnetic levitation trains, are composed of individual travel route elements.
- Track elements known from the market for a magnetic levitation train are concrete parts which are manufactured on site.
- the guideway elements are to be prefabricated as metal parts in a factory in the future. These metal parts are then to be brought to the track construction site and connected there in such a way that the course of the track is as continuous as possible, even with different terrain profiles.
- Project of a magnetic levitation planned route elements are e.g. 62 m long and are arranged on supports above the ground surface.
- These guideway elements are steel components made of thick-walled sheet steel. In cross section, these guideway elements have a trapezoidal box section with two upper transverse brackets in the installed position, so that an approximately T-shaped cross section is obtained overall.
- the said track elements are all of approximately the same length, they differ with regard to their detailed geometry. This includes, for example, an individual curvature about a vertical axis (curve curvature) and about a horizontal axis (height profile) running transverse to the longitudinal axis of the guideway element.
- This geometric egg Properties are individually defined for each route element in accordance with the geographical conditions at the point at which the respective route element is to be installed.
- the guideway elements are first preassembled on a system which includes clamping devices. In a further system, the guideway elements are then to be machined, e.g. B. drilled, milled and deburred. The system according to the invention specified in claim 1 is intended for this.
- the system according to the invention is constructed from a plurality of holding devices with support devices arranged one behind the other in the longitudinal direction of the system.
- the support devices can each be adjusted in their position so that each support device can be adapted to the individual geometry and position of that section of a travel element that is to be placed on it.
- the support device is designed so that the guideway element can be placed in its orientation that essentially corresponds to the later installation position. In this way, a kind of "bed" is created, which the individual detailed geometry of the respective driving reproduces elements. Because of the adjustability, different guideway elements can be produced using the same system, whereby the system costs and the manufacturing costs of the individual guideway elements are significantly reduced.
- the holding devices designed according to claim 3 are relatively robust.
- a quick and safe pivoting movement of the support device is given in the development of the invention according to claim 4.
- the training according to claim 9 is particularly helpful for increasing precision, documentation and quality assurance.
- Claim 11 aims in the same direction and also provides lateral guidance for the guideway element.
- Path elements of different widths can be accommodated by the system which is further developed according to claim 13.
- Optimal conditions for the production of a guideway element in particular for the machining of a guideway element stapled, for example, by spot welding, are created by the development of the system according to the invention. In it the track element is rather held and low vibration.

- the described settings can be made individually for each of the main bearing receiving devices 14 and tensioning and steaming devices 16, so that a guideway element 32 with a specific curve curvature can be produced or processed.
- pneumatic or manual actuating devices can also be used instead of electrical or hydraulic actuating elements.
- the system described can also be used for its final measurement.
- the position taken up by the various adjusting elements can anticipate the delay that arises when processing the guideway element, so that the delay is automatically compensated for.
