Definitions

  • the invention relates to a device for fastening rails, preferably in the form of stock rails or travel rails with associated wheel handlebar stands in the area of switches and / or crossings, comprising a base plate for the rail with a rail fastening plate such as sliding chair or wheel handlebar footplate that is detachably arranged and fixed by means of a hold-down device, wherein the rail mounting plate interacts with the rail foot and with an element preferably extending from the base plate.
  • a rail fastening plate such as sliding chair or wheel handlebar footplate that is detachably arranged and fixed by means of a hold-down device, wherein the rail mounting plate interacts with the rail foot and with an element preferably extending from the base plate.
  • a disadvantage of corresponding devices can be seen in the fact that, for example, if the rail fastening plate wears, the entire unit consisting of the base plate and the rail fastening plate must be replaced. This must be done particularly often when the rail mounting plate serves as a sliding chair.
  • the necessary requirement of a spring element also has the disadvantage that the entire hold-down device is no longer functional when the spring no longer has the required clamping force. For safety reasons, corresponding devices must therefore be checked and serviced frequently.
  • CH-A-11 99 40 and DE-B-11 42 378 show sliding chairs for tongue devices in which there is a detachable connection to the respective lower plate.
  • the sliding chair In order to hold down a rail foot in the construction according to DE-A-11 42 378, the sliding chair is fixed on one side by a spring clip. This causes high maintenance because the bracket can tire quickly. Therefore, this proposal does not in principle meet the usual safety regulations.
  • the sliding chair According to CH-A-11 99 40, the sliding chair is connected to the base by means of a screw, without ensuring that the rail foot is always held down to the required extent, since the sliding chair can possibly be pushed away from the rail. It is therefore necessary to check and adjust the sliding chair frequently.
  • a sliding chair is releasably attached to the base by means of a groove-web connection.
  • This connection alone is not sufficient to achieve a permanent hold down of the rail foot, even if provision is made to prevent the slide shoe from being inadvertently pushed out.
  • the object of the present invention is to design a device of the type mentioned at the outset in such a way that a safe and maintenance-friendly holding down of the rail foot is possible without having to choose complex design measures.
  • the kidney holder is designed as part of the rail fastening plate, which interacts with it to maintain the kidney with sections of the base plate, and in that the element is a clamping element which presses the rail fastening plate against the rail foot.
  • the rail fastening plate can be formed at least in sections in the form of a beak in the end face facing the rail foot, this region interacting with at least one wedge-shaped projection formed by sections of the rail foot and the base plate.
  • the rail mounting plate preferably extends in front of the rail foot at least partially laterally over the base plate and at least partially along its side surface and is beak-shaped in this area, the base plate below the rail foot having a greater lateral extent than in the support area of the rail mounting plate and together in this area forms wedge-shaped projections with the front section of the rail foot.
  • edge sections of the beak-shaped end face of the rail fastening plate interact with associated projections present in the edge region of the base plate.
  • edge sections of the beak-shaped end face of the rail fastening plate interact with associated projections present in the edge region of the base plate.
  • the hold-down device can be formed by legs of the rail fastening plate which encompass side projections of the base plate and have mutually facing end sections.
  • the side surfaces of the base plate can have at least one step, which are at least partially encompassed by angled legs extending from the rail fastening plate. The interaction between the steps and the leg sections not only ensures that the rail fastening plate is held down on the base plate, but also works at the same time as a guide, so that it can only be moved in the longitudinal direction of the base plate. This results in a simple construction, which also affects the mode of operation of the tensioning element. From this only a force needs to be exerted on the rail fastening plate in the direction of the rail foot to be held without forces having to be applied against lateral displacement.
  • the rail fastening plate extends to both sides of the rail, the rail fastening plate having legs extending at least below the rail and on the side that does not interact with the rail fastening plate, on the side surfaces of the base plate.
  • the free ends of the legs can now interact with clamping elements that act on the legs in the side region of the base plate.
  • fastening elements can preferably be provided at both ends of the rail fastening plate, by means of which the rail fastening plate is fixed on the base plate and can be pressed down against the rail foot.
  • the rail foot is not held down by means of a spring, which is referred to as the weak point of the known devices, so that there is a high level of stability.
  • the rail fastening plate interacts with the rail foot, in order to enable holding down.
  • the rail mounting plate is fixed on the base by means of at least one hold-down device and pressed against the rail base by means of a tensioning element.
  • the Nierderhalter therefore ensures that the rail mounting plate cannot lift off the base plate in an uncontrolled manner.
  • the tensioning element the required pressure is exerted from the rail mounting plate onto the rail foot in order to keep it from falling.
  • tensioning elements themselves, it should be noted that these can be an eccentric shape or a wedge-shaped element tapering in the direction of the base plate, so as to enable the rail fastening plate to be fixed and tensioned in the direction of the rail foot to be held down.
  • a further embodiment of the tensioning element is to be emphasized, which is characterized in that the end face of the rail fastening plate facing away from the rail has an inclined end face in at least one section, which is assigned a corresponding surface, which interact with one another, of the tensioning element. If the tensioning element is now moved in the direction of the base plate, the surface of the tensioning element sliding along the rear surface of the fastening plate ensures that the fastening plate is displaced in the direction of the rail foot to be held down and thus braced.
  • the angle enclosed between the underside of the rail fastening plate and the inclined back surface is of course less than 90 °, preferably 60 °.
  • the sliding chair can be equipped with a lubrication system that preferably acts automatically. So z. B. a lubricant cartridge can be inserted laterally in the sliding chair, which by moving the tongue lubricant z. B. on holes in the plate on the slide chair surface to the required extent.
  • the devices for fastening rails described in the figures serve to hold down stock rails as well as the inside of the running rails in the area of wheel handlebar stands, which run in the area of switches and / or crossings.
  • the stock rails are fastened in switches and / or crossings by means of sliding chairs.
  • a sliding chair (12) is detachably arranged on a base plate (10), the lateral extent of which can be greater than that of the base plate.
