Definitions

  • the invention relates to a clearing chain for a track construction machine for excavation of bedding material of a track, consisting of shovel-like clearing elements for recording and conveying the bedding material and the Broaching elements to form an endless chain connecting chain links.
  • Such an articulated clearing chain is already known from US 4,614,238. wherein the clearing chain from a variety of similarly designed and each chain elements connected by the chain link is composed.
  • the chain links are universal joints that can be moved on all sides educated. Every third chain element is fitted with one screwed of bulk material serving clearing element.
  • Such a constructive however, relatively complex clearing chain can advantageously be three-dimensional be performed.
  • the object of the present invention is now to create a Clearing chain of the generic type, with all sides being retained Movable joints the design effort can be reduced.
  • this object is achieved with a clearing chain of the type mentioned at the beginning Art solved in that between two adjacent clearing elements a chain intermediate part with two in the longitudinal direction of the chain spaced chain links is arranged, each for articulated Inclusion of a hinge pin detachably connected to a clearing element are trained.
  • a track construction machine 1 shown in FIG. 1 is via rail carriages 2 in the working direction represented by an arrow 31 on a track 3 traversable.
  • the clearing chain 4 has at its upper section one discharge end 6 and one positioned below the track 3 Recording part 7 on. The beginning is below the discharge end 6 a conveyor belt 8 for transporting ballast 9 to a bulk loading wagon 10th
  • the clearing chain 4 is between the discharge end 6 and Receiving part 7 guided in a curved guideway 11, which also in the tightest of spaces optimal recording of the below the track 3 lying ballast 9 and its transport up onto the conveyor belt 8 is guaranteed.
  • the clearing chain 4 is alternately composed of one Broaching element 12 and a chain intermediate part 13 together, each are connected by a chain link 14.
  • the chain intermediate part 13 has two chain links spaced apart from one another in the longitudinal direction 15 of the chain 14, each formed as a pivot bearing 16 movable on all sides are.
  • Each clearing element 12 has finger-shaped entrainment elements 29 and a blade part 30.
  • Each spherical bearing 16 is a spherical bearing with a joint eye 17 and a ball ring 18 which is mounted so as to be freely movable therein.
  • This comprises a hinge pin having a pin or hinge axis 19 20, which is anchored in bores 21 of the clearing element 12.
  • the intermediate chain part 13 is made of a joint connected to the two spherical bearings 16, positioned in a plane 23 extending normal to the hinge axis 19 Main part 22 formed. Centered between the two spherical bearings 16 are located on both the upper and lower side of the main part 22 - a stabilizing web 24 running normal to the longitudinal direction 15 of the chain and two stabilizing lugs 25 (see FIG. 3).
  • Each clearing element 12 has in the area of the spherical bearing 16 or the bores 21 two hinge plates 26, which form an incision 27 are distanced from each other in the direction of the hinge axis 19. How in particular 4, each joint tab 26 has a notch 28 to accommodate the adjacent stabilizing nose 25.
  • the clearing chain 4 contacts in the guideway 11 arranged slide plates 32.
