Definitions

• the invention relates to a device for adjusting the position of a rail or a rail comprising at least one rail with respect to a supporting substructure.
• ballastless systems have proven to be advantageous for certain applications and operating conditions in recent decades.
• a large range of different technical solutions was produced and evaluated in terms of their suitability for use in practical operation.
• systems in which the support points for receiving the rails already in prefabricated pre-fabricated prefabricated concrete precast slabs are integrated eg fixed track of the type "Bögl”
• DE 102 36 535 proposes a support tube divisible at the height of the upper edge of the carriageway slab by means of a desired separation point.
• components remain in the near-surface area of the deck slab, which may develop as potential sources of damage in the subsequent period of operation.
• Further disadvantages can be seen in the fact that adjustment and support take place in the region of the threshold, whereas the actual measurement takes place at the top of the rail. Due to the spatial offset between the measuring and adjustment location, the adjustment is more difficult and more complex.
• regulatory portals are used, which are supported on the support layer and raise the rails of the track grating medium rail pliers and align.
• the regulatory gantries must be frictionally connected to the ground by means of screwing or dowelling and straddle the designed track grid.
• a large number of extremely bulky regulatory portals have to be installed on a section of a track grid to be adjusted. Due to their dimensions, these gantries can not be moved manually, but require the use of additional lifting and transport means for handling the gantries. Due to the complex construction, these devices also bind a lot of capital. With efforts of several hundred meters a day, a large number of these capital-intensive portals must be procured and stored. In switch areas, these portals can not be used because they can no longer span the width dimensions of the track grid occurring there due to their construction. Likewise, no use in areas of limited space environments is possible, such as in tunnels or in trough structures.
• DE 199 23 329 A similar device is known from DE 199 23 329, which likewise comprises the entire width of the track grid spanning portals. Also in this solution, rail grabs are used, which, however, deviating from the known from DE 101 31 655 solution from the portal down to reach under the rails. The disadvantages known from DE 101 31 655 fully apply to this device as well.
• a third known, developed by the company "Pfleiderer” solution variant (see company publication “Rheda 2000” Pfleiderer AG, Neu hypocalc / Upper Palatinate, April 2003 / A01 / 0280879/1 / 04.03) finally provides the use of spindle brackets, which at fixed intervals along the longitudinal axis of the rail - usually in every third sleeper - be mounted on both rails of the track.
• Such a spindle bracket essentially comprises a rail foot force and form-fitting under cross base plate.
• a vertically oriented threaded bolt is guided through a threaded bore of the base plate and supported in a blind hole in the support layer of the fixed track.
• the base plate While the vertical spindle remains stationary under the mass of the track grid at the point of contact with the support layer, the base plate carries out the change in length of the rail. This leads to uncontrollable deformations in the adjusting devices, which is not only unusable thereby, but also can not be removed from the concrete slab plate with bent vertical spindles.
• the invention has for its object to provide a device for adjusting the position of a rail or a rail comprising at least one rail with respect to a supporting base, which allows an efficient and easy adjustment even in the fürhöhungs Kunststoffe of track curves.
• the adjustment should be independent of any changes in length of the rails and thus in the case of strong changes in length again easily disassembled from the concrete deck slab.
• the device should have a low mass, so that production and transport of the device can be designed as inexpensively as possible.
• the measuring and adjusting locations should be arranged as close as possible to each other.
• the device consists of at least one fixing element (2) acting directly on the rail (1), which can be fixed by means of least one about an axis parallel to the longitudinal axis of the rail (1) axis tiltable connecting element (3) supported on the supporting surface.
• the invention advantageously proposes, by means of a tiltable connecting element, always to provide an adjustment system which is also horizontally and vertically aligned in absolute spatial coordinates. In this way, the specified setpoints can be set efficiently and quickly without disturbing interactions.
• the inventive concept provides that the or each tiltable about an axis to the longitudinal axis of the rail (1) parallel connecting element (3) with at least one adjustable adjusting element (5) for horizontal adjustment of the rail and / or at least one adjustable adjusting element ( 7) is connected for vertically adjusting the rail with respect to the supporting ground.
• each adjusting element (5) for horizontal adjustment of the rail a perpendicular to the rail longitudinal axis slidable carriage (4) which receives the tiltable connecting element (3) drives.
• the invention proposes that the carriage (4) is supported in a vertical direction with respect to the supporting surface on at least one between at least two adjusting elements (7) for vertical adjustment of the rail guided base plate (6).
• the base plate forms a plane along which the carriage and thus also mounted on this carriage rail can be moved at right angles to the rail longitudinal axis.
• the or each adjusting element for vertical adjustment of the rail is designed in the form of a spindle rod (7), which is non-positively and / or positively connected to the supporting ground.
• a useful complement to the inventive concept provides that the or each adjusting element for vertical adjustment of the rail by means of a device for preventing a caused by the rotation of the spindle rod (7) lateral emigration on the supporting surface is supported. This may be a walk protection in the execution of a grained sheet, wherein the rounded tip of the vertical spindle is seated in the grain. In the case of a more developed slope, the use of a provided with a welded sheet metal washer is provided. On drilling work on the support layer as well as welding work on the reinforcement layer can thus also be dispensed with in an advantageous manner.
• the or each tiltable connecting element (3) is designed in the form of a curved bearing bar, which is mounted in a fork-shaped recess of the carriage (4).
• the or each fixing element (2) has a free relative mobility between rail and fixing element in the rail longitudinal direction.
• the adjusting device is decoupled from thermally induced changes in length of the rail.
• An advantageous embodiment of the invention in this context provides that the or each fixing element (2) as a foot of the rail (1) form-fitting embracing rail plate is executed. This can be done for example in the form of a U-shaped running rail plate.
• FIG. 1 shows a sectional view of the device according to the invention
• Figure 2 is a plan view of the inventive device (without rail and bearing bar);
• the track grid itself is constructed in a manner known per se from rails of the type UIC 60 (1) and sleepers of the type B 355. In the - viewed in the rail longitudinal direction - center of every third sleeper compartment an inventive adjustment is now applied to the underside of the rail foot.
• a pre-assembled base plate (6) is introduced into the free space between the rail and the base layer.
• the pre-assembly of the base plate can already be done decoupled in time as a preparatory measure for the actual work on the track grid.
• the device according to the invention is thus always "in the water.”
• the fine adjustment can be made via the spindle nuts (10) or the spindle screw (7)
• the vertical spindles can be unscrewed from the carriageway slab at a defined curing time. the, with which the derivation of the force exerted by the track grid weight on the carriageway plate passes.
• the base plate, together with the horizontal spindle, the sliding carriage and the track plate in the transverse direction of the track is pulled out through the intermediate space still remaining between the rail lower edge underneath the upper edge of the track plate.
• the holes left behind by the vertical spindles in the deck slab are filled and smoothed.
• the components of the Wandertikes remain as lost parts in the surface of the interior of the carriageway slab.
