Definitions

  • wing rails Centerpiece for switches or crossings with a centerpiece tip arranged between wing rails, in particular a movable and spring-movable centerpiece tip, the wing rails being essentially stationary on fastening plates such as e.g. Rib plates are fastened and sections of the wing rails and the frog tip rest between the fastening plates holding the wing rails on an at least partially plate-shaped driver device fastened to the frog tip and a foot-side section of the frog tip extending in the main axis direction is partially surrounded by the driver device.
  • fastening plates such as e.g. Rib plates are fastened and sections of the wing rails and the frog tip rest between the fastening plates holding the wing rails on an at least partially plate-shaped driver device fastened to the frog tip and a foot-side section of the frog tip extending in the main axis direction is partially surrounded by the driver device.
  • a centerpiece of the type described above is known from DE-AS 1 272 951.
  • An extension of the tailpiece is screwed to two hold-down brackets that extend below the wing rails to prevent the tip of the frog from springing up.
  • the frog tip or the frog block is supported between wing rails on a base such as a sliding chair, whereas the wing rails largely originate from documents such as rib plates. There is also the possibility that wing rails are firmly attached to the sliding chairs on which the frog tips are moved.
  • the present invention is based on the problem of developing a frog of the type described at the outset in such a way that the same conditions are always formed in the transition region between wing rails and frog tip, so that in particular it is ensured that a relative movement - viewed in the direction of the main axis of the wing rails or the Centerpiece tip - is largely excluded.
  • the problem is solved in that the foot-side section of the frog tip extending in the main axis direction moves through the plate-shaped area of the driver device, a force acting on the section in this way preferably by means of plate springs which extend between the underside of the plate and an abutment, that when the centerpiece is passed through a rail vehicle, the centerpiece tip rests on the driver device which rests on the underside of the wing rails.
  • the section is preferably a pin extending from the foot area of the frog tip, on which preferably act the leaf springs which hold the frog tip down on the driver device or other suitable spring elements.
  • the measures according to the invention ensure that the wing rails and the frog tip always rest on the top of the driver device, so that a rigid unit is formed, which excludes a relative movement between the wing rail and frog tip in the direction of the main axis of the track sections; because on the top of the driver device, the wing rail and thus also the centerpiece tip always remain when driving through a rail vehicle.
  • the centerpiece tip is consequently held on the driver device lying on the underside of the wing rails, so that lifting is not possible.
  • the spring element holding the centerpiece tip on the upper side of the driver device extends between the underside of the plate-shaped region of the driver device and an abutment, such as a disk, which starts from the pin.
  • the driver device can be adjusted in the direction of the main axis of the centerpiece tip in such a way that the wing rails do not more on top of the driver device. Rather, the driver device is pressed down by the frog tip and thus the wing rails, so that there is no contact between the driver device and the wing rails when the frog tip is pivoted relative to the wing rails.
  • the driver device can be part of a housing on which a drive device such as a cylinder-piston arrangement is supported, through which the force caused by the spring is overcome when force is applied in the direction of the underside of the housing, thereby removing the housing from the frog tip and thus is pulled away from the wing rails and thus releases the latter.
  • a drive device such as a cylinder-piston arrangement
  • FIG. Shows a section of a frog with a frog tip (10) and the wing rails (12) and (14) assigned to it, but this does not limit the invention. Rather, the idea to be derived from the invention can also be applied to other track sections.
  • the centerpiece tip (10) is designed to be movable as well as spring-movable.
  • the wing rails (12) and (14) are fastened on fastening plates, not shown, whereas the frog tip (10) is movably arranged on sliding chairs, also not shown.
  • the mounting plate and sliding chair can form a single unit.
  • the wing rails (12) or (14) and the centerpiece tip (10) bend, a different deflection occurring in particular when a rail vehicle or its wheels to be considered only on the wing rail (12) or . (14) and do not yet roll on the centerpiece tip (10).
  • different overflow areas can be formed, which lead to undesired wear of the frog tip (10) and thus inevitably to an exchange of the frog block.
  • this relative movement in the direction of the main axis (16) of the frog tip (10) is prevented by the fact that between or in the area of the usually available documents, i. H. Fastening plates or sliding chairs, driver devices (18) are arranged, which start from the centerpiece tip, but on which the wing rails (12) and (14) are loosely arranged.
  • the frog tip (16) is movable in the manner described below, but at least when driving on the frog essentially as a unit with the driver device (18) so that wing rails (12), (14) and frog tip (10) on one Place the surface firmly.
  • the driver device (18) consists of an upper plate (20), from which legs (22) and (24) extend, which in turn are connected by a base plate (26). Other suitable constructions for the driver device (18) are also possible.
  • the wing rails (12) and (14) can rest on the top (28) of the plate (20) with their feet (30) and (32). This takes place at least in relation to the wing rail being used.
  • the centerpiece tip (10) has a pin (34) on the underside which passes through a corresponding recess (36) in the plate (20).
  • the driver device (18) is thus fixed to the frog tip (10), but is movably connected in the manner described below.
  • the centerpiece tip (10) is continuously subjected to a force in the direction of the driver device (18), which in the exemplary embodiment is caused by disc springs (40), (42) which are located between the underside (44) of the plate ( 20) and an abutment (46) extending from the pin (34).
  • the corresponding wing rail (12) or (14) When driving through a rail vehicle, the corresponding wing rail (12) or (14) rests on the upper side (28) of the plate (20), which is pressed towards the frog tip (10) in such a way that the frog tip (10) can speak on the top (28).
  • the driver device (18) Since the driver device (18) must also be moved when the frog tip (10) is adjusted, it should be ensured that static friction between the wing rails (12) and (14), i.e. the feet (30) and (32) and the top (28) of the plate (44) is reduced or avoided.
  • a cylinder-piston arrangement (46), (48) is supported, the piston (48) with the pin (34) of the frog tip (10) is connected.
  • the cylinder (46) can, for example, be attached to the driver device (18), specifically in the exemplary embodiment on the legs (22), (24) or the base plate (26). If a fluid now acts on the piston (48) in the direction of the arrow (50), the prestressing force caused by the plate springs (40) is overcome, so that the driver device (18) can be moved relative to the frog tip (10) because this lies in front of and behind the driver device (18) on sliding chairs. By pulling down the driver device (18), the feet (30) and (32) of the wing rails (12) and (14) are free, so that the tip of the frog (10) can be easily adjusted.
  • driver devices (18) in a switch or crossing area depends on their design and requirements. Corresponding driver devices (18) can thus always be provided between successive sliding chairs or fastening plates. Alternatively, there is the possibility of arranging corresponding driver devices at a greater distance, that is to say not assigning such to each sliding chair or each mounting plate. Also, only one driver device (18) can be provided directly in the transition area.
  • a centerpiece for switches or crossings with a centerpiece tip (10) arranged between wing rails (12, 14), in particular a movable and spring-movable centerpiece tip is generally proposed, the wing rails being essentially stationary on fastening plates such as e.g. Rib plates are attached.
  • a driver device emanates from the Her Foundationspitze, on which the wing rail being used rests.
