Definitions

• the invention relates to a rolling device for a movable frog point with a link strip and with at least one roller and at least one roller bearing, which is fixed to a stationary part of the switch.
• Such a device has become known for example from WO 94/26976 AI.
• this known rolling device is on the foot side of the frog tip directly or indirectly from an element which has a along or approximately along the central axis of the frog point extending projection, the element interacts with a rolling element whose central axis in or approximately in one between the rempligel ⁇ chiene extending symmetry plane extends.
• the disclosed in WO 94/26976 AI rolling device is used to support the frog point in the Umstellterrorism from one investment position in the other.
• the roller guide on its surface facing the roller two outer concave sections and a central, preferably plateau-like, section on.
• a guideway is provided which is shaped such that the frog point is lifted by the sliding chair as the guideway slides over the rolling element.
• Similar rolling devices are also known for tongue rails, WO 94/02682 AI, for example, a rolling device can be removed, in which the roller cooperates with spring elements.
• a rolling device can be removed, in which the roller cooperates with spring elements.
• the known rolling devices are not readily suitable for retrofitting into existing track systems.
• the present invention now seeks to further facilitate the installation of a movable frog tip rolling device while providing the ability to provide corresponding support for the frog tip at multiple locations along the axial length of the frog point with a minimum of adjustments, and more particularly using identical ones Spring elements to allow.
• the inventive construction essentially consists in that the roller (s) is mounted on one arm of a two-armed lever (are) that the pivot bearing of the lever is arranged in a carrier connected to a stationary part of the switch and that the role or roles facing away arm of the two-armed lever against a spring with adjustable spring force is pivotable.
• rollers on one arm of a two-armed levers are mounted, wherein the pivot bearing of the lever is arranged in a connected to a stationary part of the switch carrier, it is possible in a simple manner subsequently simply set the corresponding carrier to simply push the two-armed lever side, whereby the installation work essential is relieved.
• the arm of the two-armed lever facing away from the roller or rollers can be pivoted against a spring with adjustable spring force, it is possible in a simple manner to define the desired spring force, the adjustability of the spring force outside the range of the movable frog tip without hindrance is made possible in a simple manner.
• the training is such that the Hebelarmzier the two-armed lever of a switch is chosen the same and each shorter lever arm carries the role (s), then it follows that in the longitudinal direction of the core adjacent rolling devices identical spring elements can be used, and in each case the same actuating forces can be used to adjust the spring force. It is therefore not necessary to define different spring elements depending on the installation situation, and the same adjustment paths or the same adjustment forces are used in each installation position. In this way, when retrofitting a particularly simple adjustment and thus a particularly safe subsequent assembly.
• the determination of the carrier can, as already mentioned, be carried out in a particularly simple manner outside the area of the wing rails on the support structure for the movable frog point.
• the training is in this case made such that the carrier is fixed to the wing rails or the support structure of the switch and that the adjusting device for the spring in plan view outside the wing rails or the support structure is arranged, wherein the pivot bearing of the lever in a substantially U-shaped carrier and in particular in or on the Side cheeks of the wearer is provided.
• Such a cross-sectionally substantially U-shaped carrier whose side cheeks carry the pivot bearings of the lever, allows in a particularly simple manner, the two-armed lever in the longitudinal direction of the U-shaped carrier and thus inserted transversely to the rail longitudinal direction and pivotally fixed in its respective position , For the fine adjustment, it is thus sufficient to position the pivotable lever accordingly and to set the spring in accordance with the Hebelarmanno to the same value for all positions.
• the training be made so that the lever arm ratio is 2: 3 to 1: 3, preferably 1: 2, which can be found with relatively small springs springs Aus GmbH.
• the two-armed lever can be designed differently with different lever arm ratio for different installation situations.
• the adjusting device required for adjusting the spring force can be positioned in each case where a particularly easy handling is possible.
• FIG. 2 shows a sectional view along the line II / II of FIG. 1
• FIG. 3 shows a section according to the line III / III of FIG.
• a center piece with a frog point 1 and wing rails 2 and 3 is shown.
• the rolling devices according to the invention are referred to, wherein, as shown in the views of Figure 2 and Figure 3, the rolling device 7 fixed by means of a support structure on the wing rails 2 and 3 and the rolling device 6 after the leaking of the wing rails the base plate 4 is fixed.
• the rolling device 7 is shown, wherein the frog tip 1 is in abutment against the wing rail 3 and with the foot of the frog tip 1 a link bar 8 is connected, which cooperates with a mounted on an arm 9 of a two-armed lever 10 roll 11 ,
• the two-armed lever 10 is pivotally mounted by means of a pivot bearing 12 in a stationary U-shaped support 13, which is clamped on the support members 14 and 15 and the clamping elements 16 and bolts 17 to the wing rails 2 and 3.
• the roller 11 facing away from the arm 18 of the two-armed lever 10 is pivotally mounted against the spring 19, wherein the spring force of the spring 19 by means of the adjusting bolt 20 can be adapted to the respective needs.
• the frog tip 1 is in a Umstellterrorism in Direction of the arrow 21 raised from the base plate by the formed on the link bar ramp runs onto the roller 11 and so rests with their trained with increased height area.
• the Umstellterrorism the frog tip 1 is facilitated and minimized wear.
• the roller 11 via the ramp shown on the left in the drawing, again reaches the area of the guide strip, which is designed with a lesser height, so that the frog point 1 in FIG System passes to the wing rail 2 and in turn rests on the base plate.
• the rolling device 6 is now shown, which is not fixed to the wing rails, but on the base plate 4 in contrast to the rolling device 7.
• the Umstellterrorism the frog point over a smaller Umstellweg and it is therefore adapted to the shape of the guideway on the guide rail 8 to the lower adjustment.
• the frog point 1 consists in this area of the main tip 22 and the Beirade 23. Otherwise, the reference numerals used in Figure 2 for the same parts were retained.
