Definitions

  • the invention relates to a device for securing a safety construction to a rail, said device having an alongated part, as in the shape of a tube, that can be slid underneath the rail, the free end of said tube being provided with a hook-shaped part which might grip across one side of a rail foot, a bush being slidably, but not rotably, positioned on said tube at a distance from said hook-shaped part and being provided with a lip which might crip across the other side of the rail foot, means being present for locking said bush on said tube.
  • Such a device is known by EP-A-0 708 204 and serves for mounting a safety construction, such as in the shape of a fencing, to a rail.
  • This fencing is employed for protection of the railroad workers.
  • said construction has to be suitable for use on different widths of the foot of a rail.
  • the object of the invention is to provide a device in which deviations in the width of the rail foot can be easily compensated and which device can be mounted very quickly.
  • the upper surface of said bush is provided with a pivotably connected cam which can cooperate with a toothing mounted in or on the upper surface of said tube, said cam and toothing being arranged such, that said cam and thus said bush can be locked in the position in which the lip, connected to said bush, is positioned above the foot of said rail.
  • the bush can be slid across the tube and towards the rail foot. This can be done quickly while during this displacement, the cam snaps across the teeth and will abut against one tooth of the toothing in an end position of the bush. This prevents the bush from making a backward movement. This allows a considerable reduction of the time during which the railway can not be used.
  • said cam extends through a slot in the upper plane in said bush and is operated by a draw spring, which is connected to said bush and said cam in such a way that the cam will take up a stable position in both positions.
  • said hook-shaped part coupled to the free end of the tube has a sliding portion, which is slidably mounted in the tube and is pulled into the tube by a spring, until a part of said sliding portion projecting radially from the tube is pulled against a stop connected to said tube.
  • said hook-shaped part need only be displaced across a small distance, to wit basically across a distance being smaller than the distance between two teeth of the toothing, the spring between sliding portion and tube is able to exert a relatively large force. Further, the sliding portion can be caused to be displaced only across the required distance. This will give an appropriate connection of the tube to the rail.
  • the bush has two spaced-apart hooks that can grip across the rail, and that a magnet has been mounted between the hooks, that can abut the rail. This allows for further simplification of mounting.
  • the device illustrated in the drawing first comprises a tube 1, in this case having a rectangular cross-section, extending outwards from rail 2 and being connected to a fencing not illustrated, being the safety device for the railway, through an extension 3.
  • hook-shaped portion 4 At the free end of the tube 1 is a hook-shaped portion 4 that is provided with a sliding portion 5 which is slidably received in the tube and is pulled inwards into the tube by a spring 6. The distance across which said sliding portion 5 can move is only small, to wit not greater than the distance between two teeth of the toothing described here after. Hook-shaped portion 4 extends across the foot 7 of rail 2.
  • a bush 8 is slidably mounted on the tube 1.
  • the bush is provided with a slot 9 which holds a cam 10, which is pivotable around a shaft 11, which is supported by lips 12 protruding upwards from the bush 8.
  • a spring 13 can extend between the cam 10 and the bush 8, so that the spring will pull the cam to the two extreme positions.
  • the spring 13 might be omitted if the cam 10 is designed such, that due to its weight it will be moved to the position illustrated in the drawing, in which it engages the toothing 14.
  • the cam 10 is provided with an edge that can abut a tooth of toothing 14, which is arranged in the upper surface 15 of said tube 1.
  • Bush 8 is further provided with two hooks 16 that can grip across the base 7 of the rail 2.
  • tube 1 is slid underneath the rail 2 until the hook-shaped portion 4 is located behind the foot 7 of the rail 2. Hook-shaped portion 4 will then be pulled across the foot 7 and after that the bush 8 is slid towards the rail 2, until the hooks 16 extend across the foot 7 of the rail 2.
  • the cam 10 On displacement of the bush 8, the cam 10 will snap across the toothing 14, possibly tensioned by the spring 13. In the end position of bush 8, the edge of the cam 10 is positioned behind a tooth of toothing 14 and the bush can not be pulled back.
  • the cam 10 When demounting the device, the cam 10 will be pivoted to the other position and be maintained in this position by the spring 13 so that the bush 8 can be slid and its teeth 16 will be released from the foot 7 of the rail 2. Then, the tube can be slid towards the rail 2 until the hook-shaped portion 4 is free from the foot 7 and can be pulled out from underneath the rail 2.
