Definitions

  • the invention relates to a clearing and conveyor chain for the transport of ballast ballast of a track, consisting of articulated and chain links guided in a conveyor trough and fastened to them Scraper blades above the end distanced from the chain link an edge of the scraper blade protruding finger-shaped Have scratch fingers.
  • the chain is in two on opposite sides of the machine frame articulated chain guide longitudinal tracks and one across the Track grating feasible chain guide cross track over pulleys in such as a triangular or polygonal shape and with the help of a drive rotatable.
  • the scratch fingers are made of wear-resistant material and can be detached connected to the scraper blades. So that the scratch fingers after advanced wear can be replaced. Such scratch fingers are already known from AT 349 051 B.
  • the object of the present invention is now to create a Clearing and conveyor chain of the generic type, with the relatively small constructive effort a quick and easy exchange of worn out Scratch fingers is possible and the transport and conveying performance reducing falling through or jamming of gravel stones between the scratch fingers is reliably excluded.
  • This task is carried out with a clearing and conveyor chain of the generic type Art solved in that the scratch fingers are formed in two parts, a first part by a finger-like protruding part connected to the scraper Carrier and a second part by an attachable to the carrier and is formed by a fastener releasably connected to a protective cap, with a finger-shaped between each of the scratch fingers Blade element projecting over the edge of the scraper blade is provided is.
  • This two-part training favors a relatively wide, perpendicular to Direction of conveyance, working surface transporting the ballast Protective caps, which means that between the adjacent scratch fingers Space can be made relatively small. So that one undesirable reduction in transport performance due to between the Exclude scratching fingers from falling gravel stones. On the other hand but can be narrow with respect to the direction of conveyance Training of the scratch fingers an optimal tear effect for a quick tear off can also be retained from encrusted gravel stones. Furthermore comes with the attachability of the protective caps and their - as a result of broader training - lower number of changeover times for renewal much simplified.
  • the pluggability is an easy one ensures a tight connection between the driver and the protective cap, thereby the impact forces when the gravel stones are torn loose can be easily taken from the track bed.
  • the driver acting as a fixing member is completely covered by the protective cap, so that even after a long period of use, the driver itself does not show any wear subject and ensures a problem-free replacement of the protective cap remains.
  • a clearing and conveyor chain 1 consists of a large number of chain links 2 together, each second with a scraper 3 to Transport of ballast ballast is connected.
  • the clearance and conveyor chain 1 lies on a sliding and conveying plane 4 of a conveying trough 5.
  • Any scraper 3 is - as can be seen in Fig. 2 - with an edge 6 finger-shaped protruding scratch fingers 7 equipped.
  • Each of these three scratch fingers 7 is formed in two parts, wherein a first part by a finger-shaped connected to the scraper blade 3 driver 8 projecting over said edge 6 and a second one Part is formed by a protective cap 9 which can be plugged onto the driver 8 is.
  • This completely enclosing the driver 8 protective cap 9 is made wear-resistant material formed and releasable by a fastener 10 connected to the driver 8.
  • the trained as a heavy duty pin 11 Fastening means 10 is in a on the edge 6 of the scraper blade 3 adjacent end region 12 (see FIG. 3) of the driver 8 positioned.
  • each of the scratch fingers 7 is a finger-shaped over the edge 6 the scraper blade 3 projecting blade element similar to a driver 8 13 provided that is not covered with a protective cap. This means falling through which reduces transport and conveying performance or jamming of gravel stones between the scratch fingers 7 reliably locked out. Since these blade elements 13 are shorter than the neighboring ones Scratch fingers 7, the wear is reduced accordingly.
  • Each scraper blade 3 has one with respect to the conveying direction (arrow 14 in Fig. 1) front working level 15 for transporting the ballast.
  • the fastener has a longitudinal axis 16 10 arranged at an angle to the working plane 15 of the scraper blade 3.
  • the front working surface 17 of the protective cap 9, which is immediately adjacent to the sliding and conveying plane 4 is with a Wear plate 18 connected from a particularly wear-resistant material.
  • the protective caps 9 with their work surfaces 17 arranged in a common plane 19.
  • the heavy-duty spring pin 11 through a bore 20 of the driver 8 and two opposite one another Bores 21 of the protective cap 9 (see Fig. 4) passed through.
  • a truncated pyramid-shaped design of the driver 8 is a backlash-free and tight fit of the protective cap is guaranteed.
