Definitions

  • the invention relates to a clamping forceps for frictional connection with a rail for their movement in the rail longitudinal direction.
  • the object of the present invention is now to provide a generic Clamping pliers, which are also - with respect to a normal to the rail longitudinal direction running direction - tightly lined rails allows easy removal of a single rail.
  • Figs. 1 to 5 clamping pliers 1 for non-positive connection with a rail 2 has two normal to the rail longitudinal direction mutually pivotable jaws 3. These are around in Rail longitudinal direction extending pivot axis 4 pivotally a jaw holder 5 stored. Each jaw 3 points to one of the jaw holder 5 further distanced end one to rest on a Rail 6 provided rail foot 7. Between this and the pivot axis 4 is located toward the opposite Jaw 3 protruding, rotationally symmetrical rail head nose 8. The distance between the located on a common jaw 3 End medicinalen Schienenfußnase 7 and the rail head nose 8 is slightly larger than the normal distance to the rail longitudinal direction a (Fig. 1 and 2) between a rail head lower edge 9 of a rail head 10 and the rail 6.
  • Each jaw 3 is with respect to their normal to the pivot axis 4 extending Longitudinal direction to form a blocking portion 11 over the Swivel axis 4 also formed extended. Between the two Blocking portions 11 of the jaws 3 is a blocking part 12 to a Axis 13 pivotally mounted on the jaw holder 5.
  • the rails 2 are under close juxtaposition - like not shown here for the sake of clarity - on a transport wagon stored and deducted from the wagon on a track construction site.
  • the blocking part 12 of the clamping jaw 1 for releasing the pivoting swung up (see Fig. 1 to 3), after which the two jaws 3 be swung apart. In this position is a problem Inserting each jaw 3 between two adjacent rails 2 possible.
  • the rail head lugs 8 and the Schienfußnasen come 7 each between rail 6 and rail head 10 in the area a rail web 21 of the withdrawn rail 2 to lie (Fig. 1 to 3).
  • clamping forceps 1 are for the sake of simplicity functionally identical parts with provided the reference numerals used in the first embodiment.
  • FIG. 6 and 7, simplified version of a clamping pliers. 1 has two jaws 3 rigidly connected to the jaw holder 5.
  • the clamping tongs 1 under inclined position (s. dash-dotted lines in Fig. 6) at a rail end 16 with the Rail foot and rail head lugs 7,8 between rail head 10 and Rail foot 6 are inserted.
  • a tensile force is exercised, it comes in turn on the leverage to a pressing the Schienenfußnasen 7 to the rail 6 and the rail head lugs 8 to the rail head lower edge 9.
  • this must be under an angle above the rail end 16 in addition Rail longitudinal direction to be moved.
  • each Rail head nose 8 is mounted on a pivotable on the jaw 3 Attached bracket 17 and through a bore 18 of the jaw 3 can be passed.
  • the pivotability of the holder 17 about an axis 19 is supported by a pivotally mounted on the jaw holder 5 Blocking device 20 blocked.
  • This clamp 1 can be easily placed on the deducted rail 2 be by the two rail head lugs 8 each in their outer Pivoting position (see Fig. 9) are brought. After putting the Clamping pliers 1, the two rail head lugs 8 are pivoted to each other and blocked by the blocking device 20. This is when applying a tensile force on the clamping jaw 1, the already described non-positive connection via rail foot nose 7 and rail head nose 8 producible. To remove the clamping pliers 1 are the blocking device 20 and the two rail head lugs 8 to pivot.
