Description

  The present invention moves the longitudinal chain section of the removal chain located on the machine frame, working under the track to receive the ballast, from the transfer position to the working position adjacent to the sleeper end in the track direction. And the method of transfer.

  Already according to U.S. Pat. No. 4,614,238, U.S. Pat. No. 4,014,389, or German Patent 3,151,652, there is a removal chain for receiving ballast, which is circulated around an endless track. It is known. The removal chain mainly consists of one lateral chain section in contact with the ballast roadbed and two longitudinal chain sections that are pivotally connected to the lateral chain section. Especially when moving the longitudinal chain section from the transfer position to the work position, there is a risk that the boundary of the side of the inner space will be exceeded, so the adjacent track that touches the work track must be blocked for safety reasons. I must.

  The object of the present invention is to provide a method of the type mentioned at the outset so that a safe transfer of the longitudinal chain section to the working position is possible.

  This object is achieved according to the invention by a method having the features of the characterizing portion of claim 1.

  According to this method step, the transfer of the longitudinal chain section to the working position can be carried out without blocking adjacent tracks. With the removal of the entire ballast track in a short time to clean the ballast, the original trajectory position is completely lost, so it is particularly important to be able to reference the stored value of the positive arrow. This further increases the maximum possible lateral spacing between the track lifting unit to be positioned according to the value stored to reproduce the original track position and the outer boundary of the longitudinal chain section. I know exactly. Even if the hydraulic components are damaged by the mechanical connection, additional safety measures are taken to ensure that the infringement of the interior space side is eliminated.

  Further advantages of the invention are described in the dependent claims and the description on the basis of the drawings.

  In the following, the present invention will be described in detail with respect to the illustrated embodiments.

FIG. 3 is a partial side view of a ballast cleaning machine having a removal chain. It is a figure which shows a part of removal chain seen in the machine longitudinal direction. It is a top view which shows a part of removal chain.

  FIG. 1 schematically shows a part of a machine 1 for cleaning the ballast of a track 2. The machine 1 has a machine frame 4 that is supported on the track 2 via the rail carriage 3 or movable along the track 2 via the rail carriage 3. On this machine frame 4, a removal chain 5 that receives the ballast of the track, a track lifting unit 6 that can be adjusted in the height direction and the lateral direction, a working chamber 7, and the ballast or A conveyor belt 8 for carrying new ballast is arranged. The removal chain 5 supported on the machine frame 4 so as to be adjustable in height and lateral direction via a drive device 9 consists of two longitudinal chain sections 10 and one lateral chain section 11. In the drawing, the removal chain 5 is shown in the transfer position, but the working position of the removal chain 5 is shown by a one-dot chain line.

  In the above working position where ballast can be received from the track 2 (shown in detail in FIGS. 2 and 3), the lateral chain section 11 of the removal chain 5 is located below the sleeper 12 of the track 2 The longitudinal chain segments 10 are each located at a position adjacent to the sleeper end 14 in the transverse direction 13 of the track. In order to transfer the removal chain 5 from the transfer position to the working position, the longitudinal chain section 10 must be moved in the traverse lateral direction 13 by the drive 9 and then lowered, after which the lateral chain section 11 is inserted. can do. In this case, the track 2 is held by the track lifting unit 6 in a position that is no longer supported by the ballast.

  In the scope of the method according to the invention for transferring the removal chain 5, first the value of the positive arrow defining the exact position of the track 2 to be processed is stored in a computer unit 15 provided in the machine 1. This can be done, for example, by a measurement run performed in advance at the first work step along the track 2 to be processed. During the measurement run, the value of the positive arrow related to the accurate trajectory position is calculated and stored, or thereafter stored in the computer unit 15.

  Next, when the track lifting unit 6 enters the track, the actual position of the track 2 in this range is measured by a transmitter (not shown) connected to the unit 6, and thereby the track lifting unit 6. The actual positive arrow value corresponding to the horizontal distance between the machine frame 4 and the machine frame 4 is formed. Thereafter, the actual value of the positive arrow is compared with the stored value of the positive arrow. For example, when the track 2 is shifted by the machine 1, the track 2 is moved to the stored accurate track position by the track lifting unit 6.

  During the transfer process, the mechanical coupling 16 arranged between the track lifting unit 6 and the longitudinal chain section 10 additionally provides for the movement of the longitudinal chain section 10 in the track lateral direction 13 as a safety measure. To control. For this purpose, a coupling part 16 in the form of a chain coupling part 19 acts on the limit switch 17. This limit switch 17 can be attached, for example, to the longitudinal chain section 10, and as soon as the internal space side 18 of the track is about to be exceeded in the direction of the adjacent track, the lateral direction of the longitudinal chain section 10 Stop moving. Thereby, the rail transport along the adjacent track can be maintained even while the removal chain 5 is transferred.

  In order to increase safety, a cable connection connected to the limit switch 17 can additionally or selectively be provided between the track lifting unit 6 and the longitudinal chain section 10. This cable connection serves to limit the maximum lateral movement of the longitudinal chain section 10 when transferring the longitudinal chain section 10 to the working position, and if the mechanical coupling 16 described above fails. It is effective for.
