Definitions

  • Figure 1 shows, from one side, the parts that are involved, and how they are applied for this standard.
  • Figure 2 shows same parts from above. In addition it shows a wedge (7), described in this application.
  • Referred standard describes a movable part (4) that locks rail (2) to sleeper (1).
  • This movable part will from now on be referred to as a clip.
  • Its movement to and from a rail is governed by the shape of a metal plate (3) in which it resides.
  • This metal plate is hold by a sleeper of concrete into which it is molded, and the clip can be moved so that one of its ends moves from a position from the inside of the metal plate to a position where it is placed over the foot of the rail.
  • This end is also dressed in a plastic cover (5) with bevelled sides (6).
  • the clip's other end is hold by tracks on the metal plate's outer side.
  • a skewer for disconnecting rails from sleepers, by placing it against the rail and bend the attached clip away from the rail.
  • an apparatus is used for this, an apparatus that is moved from sleeper to sleeper that is to be disconnected. But even with such a machine the work may be time consuming.
  • the alternative to use many men, each equipped with a skewer, is neither practical nor in terms of costs viable.
  • Mentioned wedge is designed to be pressed between the rail's vertical part and described clip's plastic cover, so that clips can be pushed away from the rail's foot, and by doing this rails will be disconnected from sleepers.
  • the wedge could, by using the sledge, be moved forward with a relative high speed and in a short period of time release long distances of rails.
  • This has been tested by the use of a tractor, which for this purpose, used a tooth on an excavator. As this was not a precise and for the purpose designed tool, and due to the risk for damages on the clips, it cannot be permanent solution. But the test showed that the principle works, and this with a velocity only limited by the tractor's velocity.
  • the wedge can be connected to springs that prevent damages, both on clips that are stuck and on the wedge itself with mounting.
  • the wedge's side towards the clips could be made in a material that has low friction and/or be equipped with automatic lubrication of this surface.
  • the tip of the wedge could also be given an extra wedge shaped tip (8), which lifts the clips enough to reduce their friction against the rail's foot.
  • the construction of the wedge's mounting should be done in a way that facilitates its replacements, as it will, despite different measures, be worn out.
  • a bar (18) suspended on a hinge as shown by figure 5 or a piston, powered by electromagnetism, an electric motor or hydraulic, can be used to push a clip away from the rail.
  • a spring loaded switch for an electric governing circuit could by a direct or indirect physical contact with a clip or pertaining metal plate, make a connection for this.
  • a corresponding construction to push a clip towards a rail for connecting it to a sleeper may also be done.
  • the sledge may be designed to hold the described constructions on both sides of the rail. Depending on the wedge's design it may have to adapt to which side it is to be used.
  • the sledge can be equipped with wheels (9-11) to fixate it in a correct position in relation to the rails. These wheels can be locked towards each side of a rail, and towards the rails upper- and underside of the rails upper part.
  • the sledge will have to have a sufficient length and described wheels in both ends in order to maintain a stable direction when moved. To prevent the sledge from twisting around one rail this stability can be accomplished by connection to wheels (12) following the railway's other rail.
  • the part of the sledge with wheels enclosing a rail will have to, for example with hinges (13), be able to open, before the sledge is placed on rails, and then be closed. To lock this closure, extra bars (16) with a latch (17), or a locking mechanism by the hinges (13), can be used.
  • the wheels suspension should be adjustable for an optimal fit towards the rails. Sledge-runners can be used instead of wheels.
