Definitions
- the invention relates to a centerpiece of a rail switch having a movable centerpiece tip which is guided in a sliding manner in a base frame and which is movable in contact with the wing rails and is laterally supported in the contact positions by support elements fixed to the base frame.
- the movable frog tip In the case of frogs with a movable frog tip, the movable frog tip is held on the one hand at the clamping point and on the other hand in the drive or closure levels and should in the contact positions on the wing rails come into contact with the support elements provided for lateral support of the frog tip , In fact, however, due to the bending behavior of the frog tip, an exact contact with the supporting elements connected to the base frame is not guaranteed and therefore no support of the frog tips taking into account the loads caused by the high rolling loads is given. It would therefore be desirable to create a frog in which the frog tip is adequately secured in the contact positions.
- changeover or end position securing devices In connection with tongue rails of switches, which can be moved in contact with a stock rail, changeover or end position securing devices have already become known which ensure a resilient pressing of the tongue rail against the stock rail.
- the changeover force is supported by an additional force after a predetermined changeover path.
- a force accumulator is initially charged when adjusting switch parts, after which, after a dead center position has been exceeded, the tongue rail is pressed into an end position with renewed release of force.
- the energy accumulator is formed by a compression spring, the compression spring, for example, via an angle lever with the j eider driven part or the drive is connected, as can be seen, for example, from AT 379 624.
- Such angle levers must be articulated exactly in the appropriate position, and a series of articulation points are required, via which the force of the energy accumulator is subsequently transmitted to the parts to be adjusted.
- a changeover or end position securing device is also referred to as a spring rocker.
- said spring toys are in the form of two pressure springs which are supported on the housing of the Erdkas least • and corresponding after exceeding dead center positions to take effect.
- an adjusting device for a switch with stock rails and associated switch tongues in which the adjusting device can be fixed in at least one spring element in one of two end positions.
- the tongue base is encompassed by a connecting element, which interacts with a spring rocker which is arranged on a fastening plate which is clamped on the stock rail.
- a lever element can be used as an intermediate element for the connecting linkage of the tongue in order to support the end position and can be checked. do .
- the present invention now aims to create a centerpiece in which the centerpiece tip can be better supported laterally in the contact positions and can be appropriately secured in its end position and pressed against the support elements, so that a safe crossing is made possible.
- the centerpiece according to the invention is essentially characterized in that an end position securing device which resiliently presses the centerpiece tip in its contact position against the wing rail and the support elements, which is arranged within the space delimited by the base frame and with the base frame or the support elements and connected to the frog tip.
- the centerpiece tip By arranging a end position securing device which resiliently presses the centerpiece tip in its contact position against the wing rail and the support elements, the centerpiece tip is pressed laterally in the contact position on the support elements fixed to the base frame, so that a substantially improved support is achieved. Adequate support would otherwise not be provided, because the centerpiece tip cannot be held exactly over its entire length in the contact position due to its bending behavior and its elastic deformation. Characterized in that the end position securing device fiction, according to arranged within the space delimited by the base frame and connected to the base frame or the support elements and with the frog tip, a particularly compact design is achieved, which the extremely tight space in the area of the frog tip in an optimal manner Takes into account.
- the inventive arrangement of the end position securing device prevents the end position securing device or parts of the end position securing device from projecting beyond the space delimited by the basic frame, so that parts of the end position securing device are not fixed to a holding part arranged under the rail foot must, as is known from the prior art in connection with tongue and stock rails. All in all, this results in an optimal arrangement in the area of the frog tip, and in particular the end position securing device can also be retrofitted into the frog, since the assembly is easily carried out on the base frame or the support elements.
- the end position securing device is fixed to a support part connecting two adjacent support elements.
- the subsequent installation of the end position securing device is further simplified, since the end position securing device can already be fixed in advance on the supporting part, whereby an exact positioning of the end position securing device can already be carried out.
- the end position securing device can preferably be installed in such a way that the end position securing device is connected to a holding part which surrounds the rail foot of the main tip and the rail foot of the example.
- a holding part which connects the main tip to the example tip
- the holding part encompassing the rail foot of the main tip and the rail foot of the tip is usually, as is known per se, connected to the frog tip with a bolt passing through the rail web of the main or tip in the area of its center of gravity, with only the relative longitudinal displaceability of the main tip looking back relative to the example.
- the force is introduced in the area of the center of gravity of the frog tip and thus in the area of the neutral fiber, ie approximately in the middle of the rail web, so that the occurrence of tilting moments is largely prevented.
- the training can preferably be developed in such a way that the rail-side articulation point of the end position securing device lies in the area of the center of gravity of the frog tip. Overall, the entire end position securing device is thus in the area of the center of gravity of the frog tip, so that all effective forces are in one plane.
- the end position securing device is preferably designed as a spring rocker, as a result of which a particularly compact design is achieved and both the right and the left end position of the frog tip can be secured with a single device.
- FIG. 1 shows the plan view of a section of a switch with a movable heart tip and a cast or welded base frame
- FIG. 2 shows an enlarged detailed view of FIG. 1
- FIG. 3 shows a section of FIG. 2 along the line III-III
- FIG 4 is a partial view of a spring rocker element.
- a heart 1 is shown, the base frame is designated by 2.
- the centerpiece tip 5, which consists of a main tip 3 and an example 4, can be moved or pivoted either in contact with the rigid wing rail 6 or the rigid wing rail 7.
- the movable centerpiece tip 5 is held on the one hand at the clamping point 8 and on the other hand in the drive or locking plane 9.
- Support elements 10, which are fixed to the base frame 2, are provided for exact positioning of the movable centerpiece tip 5 in the respective end positions.
- a holding part 11 can be seen which engages around the rail base of the main tip and the rail base of the example and at the same time ensures the required longitudinal displacement of the example relative to the main tip.
- the end position securing device 12 is designed as a spring rocker and consists of two compression springs 14 which are connected on the frame side to the support part 13 and are mounted rotatably on the rail side about the common axis 15 and are pivotably articulated on the holding part 11 via the connecting part 16 and the articulated part 17 are.
- FIG. 4 shows a detailed view of the spring rocker, the prestressing force of the spring 14 being able to be adjusted accordingly by turning the bracket part 19.
