Definitions

  • the invention relates to a tamping pick for track tamping machines, consisting of an axially connected pimple shaft at the upper end to the tamping drive and a pimple plate formed on the lower end, each formed as separate parts and by means of a - from a shaft extending in the longitudinal direction of the shaft and one at the Back of the pimple plate arranged connecting part existing positive - plug connection with a recess or recess can be connected to each other.
  • the tamping picks that can be used in the tamping units of track tamping machines can be set in vibration by their drives and immersed in the ballast between the individual sleepers and are added to each other in pairs for tamping the ballast under the sleepers.
  • Large forces are transferred to the tamping pick, particularly when penetrating the ballast bed, a very high penetration resistance is often to be overcome or is particularly stressed by the pressurization when the ballast is pressed together under the threshold of the tamping pick. Due to the constant intensive work with the track ballast, which is carried out with great driving forces, the actual tamping pick plates are subjected to very heavy wear.
  • a conventional tamping unit per rail has four to eight such tamping pickles per rail / sleeper crossing area, therefore eight to sixteen tamping ticks for both tracks and, for example, for a track tamping machine for simultaneous processing of two adjacent sleepers, a total of thirty-two tamping pickles are provided.
  • the pick shaft and pick plate are formed with an integrally formed stub as separate parts which can be connected to one another by means of a positive plug connection.
  • the plug-in connection consists of a plug and recess which run in the longitudinal direction of the shaft and can be plugged into one another, each of which is provided with a bore running transversely to the direction of the shaft for receiving a radially elastic connecting element.
  • the tamping pick consists of further interlocking interlocking elements, in particular with an extension extending almost to the middle of the shaft, as a result of which the entire tamping pick is very complex, uneconomical and also difficult to manufacture.
  • the radially elastic clamping sleeve serving as a connecting element or a clamping screw passing through it is often subject to jamming during installation and removal, which also impairs assembly.
  • an embodiment of a tamping pick with a separate pick shaft and pick plate in which the shaft end part has an approximately trapezoidal cross-section and the corresponding recess on the pick plate is formed by two integral parts on the back of the plate and in relation to each other Angled flanges are formed.
  • This plug-in connection which is essentially designed with a trapezoidal cross section, is intended to hold the two parts while making a non-positive connection when they are plugged into one another, since no additional securing means, for example a connecting element, is provided.
  • this tamping pick which is already used in practice, the pimple plates often get stuck in the ballast during operation or fall off when lifting off.
  • this recess open on three sides, which is formed only by the two protruding flanges, as well as the manufacture of the tamping pick shaft in the special trapezoidal cross-sectional shape, which is associated with a special surface profile to avoid sharp transitions, is very complex and therefore also uneconomical.
  • Such a, but simpler, design of a tamping pick is already known, according to US Pat. No. 376,565, with an approximately trapezoidal cross-sectional design of the shaft end part and a correspondingly shaped pimple plate.
  • the two flanges that delimit the recess in the pimple plate extend to the side edges of the pimple plate.
  • the shaft end part should be insertable and durable in the trapezoidal recess of the pimple plate while producing a non-positive connection.
  • the object of the present invention is now to provide a tamping pick of the type described at the outset, which is simple and yet very robust and where the pick plate can be quickly and easily removed and removed can be reassembled and that, despite this separate design, the entire tamping pick can also absorb large forces.
  • the plug-in connection has a pin which, in the direction of supply or in the area towards the pick plate, is designed in a stepped manner to the lower pick shaft and a pick plate which at least partially with its upper edge is arranged in this stage.
  • the pimple plate can either run approximately parallel or at a slight angle to the pimple shaft, but always with the advantage that the upper edge of the pimple plate protrudes at least partially or not completely from the shaft - or the majority of the pimple plate thickness with a smaller part protruding - there is still space in the step - which means that even when pulling out the tamping picks that can penetrate the ballast bed, the remaining hole in the ballast bed becomes smaller or no larger gravel grains go up when pulling out of the tamping pimple are transported up again.
  • a further advantageous embodiment of the invention is that the plug connection is formed essentially over the entire height of the pimple plate, in particular up to the wedge-shaped lower edge, and that the pimple plate preferably runs essentially flush or approximately parallel with its working surface to the pimple shaft.
  • essentially the entire height of the pimple plate can be used to form the plug connection, as a result of which it is particularly robust and is suitable for absorbing the highest forces. Since, in addition, the pimple plate with its working surface is essentially aligned with the pimple shaft, immersion in the ballast bed or pulling out the tamping tool, in particular with a crusted ballast bed, can be carried out more easily and smoothly.
  • the connecting or receiving part connected to the pimple plate has only a single recess or recess in the form of a conical shell section, the conical shell part resting on the pimple plate over a parabolic section surface and being welded to the outside thereof, and the pin which can be inserted into the recess is conical and is designed with a section surface which corresponds to the inner cone-shaped section and runs approximately parallel to the pin step.
  • a further embodiment of the invention consists in that the conical jacket part of the receiving part with its conical jacket section-shaped recess with an approximately circular cross section and approximately parallel to the longitudinal direction of the shaft - and preferably at a distance of approximately 1/2 to 3/4 r to the shaft axis or Corresponding to the spigot step - extending and formed by the pimple plate inner surface or final, parabolic section surface is formed and for receiving a similarly shaped conical spigot with a corresponding section surface and spigot step extends to the upper pimple plate edge.
  • This design has proven to be particularly advantageous, both in terms of manufacture and in terms of size in connection with the distance from the parabolic section surface to the outer edge of the pick shaft - since the remaining size of about 3/4 of the diameter at the lower end of the pick shaft about 7/8 of this diameter is sufficient for a robust design of the pin, in particular to be able to absorb local peak loads without breaking.
  • the conical shell part of the connection or. Receiving part with its tapered axis to the shaft axis at an angle ⁇ of about 5 to 15 °, preferably 10 °, is inclined towards the pimple plate.
  • This design results in a particularly advantageous plug connection, which due to this inclined construction towards the pimple plate is particularly advantageous when penetrating hard or encrusted ballast beds, since with this construction a lower penetration resistance can be achieved when penetrating into the ballast bed.
  • a particularly expedient embodiment of the invention consists in the fact that the upper edge of the pimple plate welded to the conical jacket part interacts with the projecting pin step of the pimple shaft serving as a stop. This configuration ensures that at least some of the forces acting on the pimple plate in the vertical direction when immersed in the ballast can be transmitted directly to the pimple shaft in the region of the pin step serving as a stop.
  • conical jacket part of the receiving part is formed on the side opposite the parabolic section surface with a further, approximately parabolic section.
  • This design has the advantage that the plug connection as a whole can be made even better for penetration into the ballast bed, with both remaining parts of the outside of the pimple plate being attached welded conical section-shaped receiving part can be achieved by machining a particularly advantageous pretension, which ensures a secure durability against falling of the receiving part from the pin when inserted into each other.
  • the connecting or receiving part and the pin can be machined by means of machining processes - in particular also to achieve a pretension when the tapered pin is inserted.
  • the connecting or receiving part and the spigot can be produced both by turning, grinding or other suitable types of method to achieve a precise fit to the spigot.
  • the pin can be connected and detached to the receiving part by a connecting element, in particular a wedge or a grooved pin.
  • a connecting element in particular a wedge or a grooved pin.
  • this measure can additionally be provided, with in particular the making of a notch for a pin or a clamping screw through the conical jacket part being very simple and advantageous and free of faults.
  • the connector from a connection or.
  • receiveing part forming and connected to the back of the pimple plate, dovetail-shaped connecting web is formed, the width of which is tapered in the direction of the upper edge of the pimple plate, and in that the pin has a receiving groove which is configured opposite to the connecting web and runs in the longitudinal direction of the pin.
  • Such a plug-and-socket connection which is designed as a tongue and groove connection, ensures, with particularly simple manufacture, an effective connection which can be carried out quickly and which is quick and easy and shock-resistant immersion in the ballast caused extreme shock loads reliably.
  • the wedge-shaped taper of the connecting or receiving part while avoiding further aids, can produce a permanent clamping effect between the pick plate and the pin.
  • the particularly simple and quickly implementable solution of the pimple plate is achieved by knocking on its upper horizontal edge, as a result of which the wedge-shaped and dovetail-shaped connecting web is released from the oppositely designed receiving groove of the pin.
  • the depth of the connecting part which runs perpendicular to the pimple plate, can be designed in accordance with a further embodiment variant of the invention, approximately according to the thickness of the pimple plate.

  • a sufficient clamping effect can be achieved for the tamping insert.
  • the solution of the worn pimple plate is also relatively easy to carry out.
  • the depth of the receiving groove of the pin can be made larger than the depth of the connecting part. This makes it easier to insert the pimple plate possible in the pin, since the back of the wedge-shaped connecting part does not rest on the base of the receiving groove.
  • the side flanks of the connecting part forming the undercut form an angle of approximately 45 to 80 °, preferably approximately 60 °, with the rear of the pimple plate.
  • Such an inclination of the side flanks with respect to the plane of the pimple plate makes it possible to produce a particularly firm connection between the pin and the pimple plate without the transverse forces on the receiving groove extending in the longitudinal direction of the pimple plate becoming too great.
  • the connecting part can be formed from two longitudinal wedge sections which are arranged in mirror image to the longitudinal plane of symmetry of the pimple plate and are spaced apart from one another.
  • a protruding projection is provided on the inclined side flank, which is designed to engage in a notch of the same design in the receiving groove of the pin .
