Definitions

  • the invention relates to a frog for points, with a heart base body and the core piece body attached and releasably attachable to the core body, replaceable insert.
  • Object of the present invention is therefore to provide a heart of the type mentioned, in which the aforementioned disadvantages are avoided.
  • the claimed in claim 1 solution is provided.
  • the attachment of the insert is carried out neither by a direct screwing nor by acting on the insert screwed wedge elements.
  • at least one clip-type fastening element is provided, which laterally engages in both the insert and / or in the centerpiece main body and / or engages over the insert and / or engages under the centerpiece main body.
  • corresponding engagement portions are provided on the side of the insert and the heart piece main body, engage in the corresponding engaging leg of the fastener.
  • the insert is releasably secured only on one side via at least one fastener, while the insert is then attached to the other side by positive engagement on the heart piece main body.
  • the insert is releasably secured on both sides in each case via at least one fastening element.
  • the screw can have a hammer head screw, which is then inserted into a corresponding slot-shaped receptacle, so that the screw shaft protrudes outward.
  • the slot-shaped receptacle is adapted to the hammer head of the screw.
  • the screw has a transversely guided through the center piece long screw- The long screw is thus inserted on one side, passed through the heart and then serves to screw the fastener.
  • the long bolt there are also two uses.
  • a bore can be provided in the heart stucco body.
  • corresponding grooves can be milled in at the top side of the core piece main body, which, when the insert rests on the core piece main body, result in a passage opening for the long screw.
  • an oblique joint is provided at the transition from the insert to the heart body in the direction of travel, By this oblique impact, the edge at the transition from the heart piece body to use when driving over virtually does not work.
  • the oblique transition can be realized in two ways. On the one hand, the transition on the insert can be tapered in a V-shape. On the other hand, however, a V-shaped incision on the insert is possible. It is understood that the heart piece main body is formed on the recess provided for use corresponding.
  • At least one engagement opening for attaching a tool is provided on the insert and / or on the centerpiece body adjacent to the insert. About the engagement opening of the insert can then be levered out of the recess.
  • the insert is located adjacent to the frog point. Since the insert is generally intended to cover only the area of the frog that is most prone to wear, the base of the insert is significantly smaller than the base of the heart stucco body. Alternatively, it is also possible in certain applications, however, that the insert extends over the entire length of the frog body, it being otherwise possible for the insert to rest on the entire top side of the frog body.
  • the heart piece main body may be formed as a one-piece, in particular milled block or consist of several parts which are firmly connected to each other.
  • a centerpiece 1 for points is shown in each case.
  • heart pieces of the type according to the invention can be used both for grooved rails and for Vignole rail turnouts.
  • the heart 1 has a heart base body 2 and a replaceable insert 3 made of a wear-resistant material that is placed on the core piece body 2 and can be detachably fastened thereto.
  • a recess 3 corresponding to the dimensions of the insert 3 is provided on the upper side of the centerpiece main body 2, in which the insert 3 is arranged essentially free of play.
  • the insert 3 itself consists of non-weldable manganese steel. Not shown are in the rest belonging to the heart 1, welded to the core piece body 2 connecting rails.
  • the insert 3 comprises the region 5 of highest wear following the frog tip 6.
  • the engagement sections 8, 9 are in each case depressions or recesses on the one hand in the centerpiece main body 2 and on the other hand in the insert 3.
  • Engaging legs 14 of the fastening element 7 engage in the respective recess.
  • the engaging legs 14 have approximately a horizontal orientation.
  • the two outer engagement legs 14 are connected to each other via a central connecting leg 15.
  • the engagement portion is provided on the upper side of the insert 3 and the underside of the heart piece main body 2.
  • the fastener 7 fully encloses the core body 2 and the insert 3.
  • the screw connection for a fastening element 7 in each case has a hammer head screw 16 whose hammer head is inserted into a corresponding slot-shaped receptacle 17 in the centerpiece main body 2.
  • the receptacle 17 is adapted to the shape of the hammer head of the hammer head screw 16
  • the same fastening elements 7 are provided, which in each case via hammer head screws 16 are attached to the heart piece body 2.
  • the engagement legs 14 and the engagement portions 9, 10 each have corresponding ramps such that the engagement legs 14 are narrowed towards the outer end, while the engagement portions 8, 9 expand outwardly.
  • FIGS. 1 to 8 it is in the embodiments shown in FIGS. 1 to 8 shown so that the slot-shaped receptacle 17 is inserted from above and accordingly accessible from above in Fig. 9, an embodiment is shown in which the receptacle 17 parallel to the direction of travel R is aligned.
  • the fastening element 7 shown in FIG. 9 has a different form from the fastening elements 7 described above, While the fastening elements shown in FIGS. 1 to 8 are mirror-symmetrical, this is not the case in the embodiment shown in FIG.
  • the lower engaging leg 14 is here on the ground, which is not the case with the other embodiments.
  • the bevels described above are more pronounced.
  • the screw for either or for two fasteners 7 each have a long screw 18 which is passed transversely to the direction R through the heart piece 1 in the embodiment shown in FIG the long screw 18 is used to attach two fasteners 7, a hole 19 in the heart piece main body 2 is provided for the long screw 18.
  • corresponding grooves 20, 21 are provided, on the one hand, on the upper side of the core piece body 2 and, on the other hand, on the underside of the insert 3, which form a passage opening for the long bolt 18 in the condition inserted into the recess 4.
  • the transition from the insert 3 to the centerpiece main body 2 in the direction of travel R is designed as a skewed joint.
  • the oblique joint runs approximately at an angle of 45 ° to the respective groove.
  • the insert 3 at its two ends tapered in a V-shape, while the insert 3 is cut in the embodiment shown in Fig. 3 and 4 at its two ends in a V-shape.
  • the recess 4 is adapted to the shape of the insert 3 such that the insert 3 is arranged without play in the recess 4 and is positively fixed in the rest in the horizontal plane.
  • the insert 3 is trapezoidally inserted into the outwardly widening trapezoidal recess 4.
  • This configuration of the recess 4 of the insert 3 makes it possible to push the insert 3 transversely to the direction of travel R out of the recess 4 and, moreover, to insert it laterally from the side.
  • FIGS. 1 and 5 Only in the embodiments of FIGS. 1 and 5 are shown at the heart base body 2 immediately adjacent to the insert 3 engaging openings 22 for applying a tool. It is understood that it is also possible in principle to provide the engagement openings 22 on the insert 3 itself.
  • the embodiment according to FIGS. 7 and 8 differs from the other embodiments in that the insert 3 extends over the entire centerpiece main body 2, ie rests over its entire surface on the entire upper side of the core piece main body 2. In the other embodiments, the insert 3 is considerably smaller than the heart piece main body 2.
  • the heart base body 2 and a one-piece block, which has been produced by erosive treatment.
  • the heart piece main body 2 of several block parts or even from rail elements, if necessary in conjunction with other (block) parts can be produced.
  • the fastening element 7 is in each case screwed to the frog base body 2 via a fastening screw 25.
  • a threaded bore 26 is directly in the heart piece main body introduced, while in the embodiment of FIG. 13, a threaded bushing 27 is provided, which is introduced into the heart piece main body 2.
  • the fasteners are in inspection boxes 23, which are closed on the top side with a lid. It is understood that it is not necessary in operations in the region of the open track body to provide such revision boxes 23.
