Definitions

• the invention relates to a frog for switches or crossings with a frog tip arranged between wing rails, in particular movable and spring-movable frog tip, the wing rails essentially stationary on mounting plates such as. B. rib plates are attached.
• 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 heart of the type described in the introduction in such a way that the same conditions are always formed in the transition region between the wing rails and the tip of the heart, 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 frog tip - is largely excluded.
• the problem is solved in that sections of the wing rails and the frog tip can be placed between the fastening plates holding the wing rails on an at least partially plate-shaped driver device attached to the frog tip, that the frog tip with a section penetrates the plate-shaped area of the driver device and during passage of the centerpiece is held down or rests on the driver device by a rail vehicle.
• the section is preferably a pin extending from the foot region of the frog tip, on which acts at least one spring element, such as a leaf spring, which holds the frog tip down on the driver device.
• 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 which rests 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 area of the driver device and an abutment, such as a disk, starting from the pin.
• an abutment such as a disk
• the entrainment device is pressed downward by the frog tip and thus the wing rails, so that contact between the entrainment device and the wing rails is avoided 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, by means of which the force caused by the spring is overcome when force is applied in the direction of the underside of the housing, whereby the housing of the centerpiece tip and thus pulled away from the wing rails and thus releases the latter.
• 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 centerpiece 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 not yet 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.
• 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 fixed to the frog tip (10), but is movably connected in the manner described below.
• 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 adhesive 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 disc springs (40) is overcome, so that the driver device (18) can be displaced relative to the frog tip (10) , since this rests on sliding chairs in front of and behind the driver device (18).
• 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 proposed, the wing rails essentially being stationary on fastening plates such as e.g. Rib plates are attached.
• a driver device emanates from the tip of the tip, on which the wing rail being used rests.
