Definitions

  • the present invention relates to a device for lifting and moving the tongue rail of a switch according to the preamble of claim 1.
  • tongue lifts Devices of the type mentioned at the outset, which are also referred to as tongue lifts, are widely used in the prior art and are used to facilitate the changeover of a switch by displacing a tongue rail in track applications.
  • the EP 0 692 570 B1 a tongue lifting device with two rollers, which are rotatably mounted on an adjustable and spring-biased Zügelheberbügel.
  • Such components have proven useful in practice. However, they have a comparatively complex construction.
  • the known tongue lifting devices are susceptible to the ingress of soiling, gravel and other environmental influences occurring in the area of railway tracks. This can lead to interference or damage to the tongue lifting devices, which significantly impairs their reliability. Therefore, the tongue lifts must be checked and maintained frequently.
  • protective measures must be taken, for example, during penetration in the area of the tongue lifting devices in order to prevent the penetration of ballast into the tongue To prevent tongue lifting device, which is cumbersome and time consuming.
  • the invention is based on the finding that the reliability of tongue lifting devices is jeopardized in particular by the penetration of foreign bodies in the region between adjacent rollers. Based on this finding, the invention provides that in a generic tongue lifting device between at least two adjacent rollers, a cover is provided, which faces the first direction and at least partially covers a passage between the at least two adjacent rollers.
  • the invention is characterized by a two-part design of the base body, in which an upper part is slidably mounted on a lower part and the displacement by the special design of the contact edges of both parts in the form of corresponding bevels angled to the displacement plane of the tongue rail on the running rail out, resulting in additionally offers a possibility to adjust the height of the rolling device. This may be necessary in particular whenever a lowering of one or more sleepers, on which the base plate is screwed, is to be compensated in order to allow the tongue rail to be always, and preferably to the same extent, carried by all rolling devices, even during prolonged operation of the switch becomes.
  • the main body is divided into an upper and a lower part, wherein the rollers are mounted on the upper part of the base body and the upper and lower parts are arranged displaceable against each other.
  • the height adjustment of the roller bearing is carried out by continuously or stepwise formed bevels in the superimposed contact edges of the upper and lower part. This ensures that in each shift state, the upper side of the upper part is parallel to the direction of displacement of the tongue rail.
  • the displacement of lower part and upper part can be carried out continuously due to the configuration of the contact edges with corresponding bevels, wherein a fixation of the Upper part can be done on the lower part in any intermediate position and thus any desired height adjustment between a minimum and a maximum value can be done.
  • one or more steps may be formed in the substantially beveled contacting edges of the top and bottom portions, whereby displacement and height adjustment may occur in increments between minimum and maximum values.
  • the design of the steps provides a particularly secure and easily fixable support for the upper part on the lower part.
  • the height adjustment of the rolling device is usually carried out by hand and preferably in that the means for fixing the upper part are solved on the lower part in its arbitrary displacement and height position, an adjustment or readjustment of the height by moving the upper part on the lower part and finally the Means for fixing, preferably screws, are tightened again.
  • the displacement of the upper part on the lower part takes place at a continuously displaceable upper part via a device for moving the same.
  • this threaded rod also has an element for engaging a conventional tool, for example a hexagonal head, on its free end protruding from the main body.
  • a device which is particularly simple and preferably continuously using arbitrary tools continuously adjustable within wide limits.
  • the design and arrangement of the cover provided between adjacent rollers can be determined depending on the nature and extent of the expected environmental influences. According to one embodiment of the present invention, however, it is preferred that the cover is spaced from the outer periphery of the at least two adjacent rollers by at most 5.0 mm, particularly preferably at most 3.0 mm. As a result, a satisfactory reliability can be achieved for most applications, without a costly production or increased manufacturing tolerances are required.
  • the base body is formed as a casting, which is preferably integrally formed with the cover.
  • At least one roller in the first direction has a projection with respect to a reference point of the base body which is larger than that of the other rollers.
  • the lifting of the tongue rail be done gradually, which not only gives a smooth operation, but also reduces the required for raising the tongue rail actuating forces.
  • a first and a second roller are provided, the first roller having a projection of 2.0 to 3.0 mm and the second roller having a projection of 3.0 to 4.0 mm in the first Direction opposite the body possesses.
  • One of the aspects of operational safety is that correct installation of the tongue lifting device must be ensured from the outset, and that incorrect replacement of the tongue lifting device must also be precluded during conversion measures.
  • the main body is provided with a label indicating the supernatant of the respective roles. As a result, handling errors when installing and removing the tongue lifting device are effectively excluded.
  • the design of the support bolts can be done in many ways in the context of the present invention. According to one embodiment of the present invention, however, it is preferred that the support bolts each have at least one stop element, in particular a collar, wherein the stop element limits an insertion depth of the support pin into the base body.
  • the stop element limits an insertion depth of the support pin into the base body.
  • the rollers are mounted on the support bolts by plain bearings, which are preferably formed by a provided between an inner peripheral surface of the rollers and an outer peripheral surface of the support pin plastic polymer layer.
  • plain bearings which are preferably formed by a provided between an inner peripheral surface of the rollers and an outer peripheral surface of the support pin plastic polymer layer.
  • Such sliding bearings have proven to be extremely durable, while ensuring a smooth and smooth operation when lifting and moving the tongue rail.
  • the plastic polymer layer has self-lubricating properties in order to ensure the advantageous properties of the sliding bearing permanently.
  • the base body has an axis of symmetry which extends parallel to the rollers. In this way it is possible within a certain rail system to install the tongue lifting device in different positions with respect to the symmetry axis, depending on the respective boundary conditions, without changing the basic function of the tongue lifting device.
  • the principles of the present invention are applicable to both adjustable and non-adjustable tongue lifts.
