EA032060B1 - Method for transferring a longitudinal section of a clearing chain of a track ballast cleaning machine - Google Patents

Abstract

The invention relates to a method for transferring a longitudinal chain section (10) of a clearing chain (5) for picking up ballast from a track (2) from a transfer position to a working position adjacent to the sleeper ends (14) wherein camber values determining a precise track set of the track to be cleaned are stored in a computing unit (15). The position of the track (2) is measured in the area of a rail lifter (6) determining current camber values, which are compared to the stored camber values and the track is moved to the stored precise track set by the rail lifter (6) in the event of any discrepancy. The movement of the longitudinal chain section (10) in the transverse direction of the track (13) for subsequent lowering into the working position is controlled by a mechanical linkage (19) between the rail lifter (6) and the longitudinal chain section (10) acting on a limit switch (17) and is halted when a clearance gauge (18) is surpassed.

032060 B1 (57) In the method of rearranging the longitudinal section (10) of the harvesting chain (5), intended for receiving crushed stone of the rail track (2), from the translation position to the working position bordering the ends (14) of the sleepers, they are accumulated in the computing unit (15) ) the length of the arrow, determining the exact position of the processed rail track. The position of the rail track (2) is measured in the area of the lifting unit (6) for straightening the rail track, forming the actual value of the length of the arrow, compared with the accumulated values of the length of the arrow, and if there is a deviation, the rail track is moved using the lifting block (6) to straighten the rail track to the exact position of the rail track. The movement of the longitudinal section (10) of the chain in the transverse direction (13) of the rail for final lowering to the working position is controlled by the mechanical connection (19) acting on the limit switch (17) between the lifting unit (6) for straightening the rail and the longitudinal section ( 10) chains and stops when the clearance profile is exceeded (18).

The invention relates to a method for rearranging a longitudinal section of a harvesting chain designed to receive crushed stone under a rail and placed on a machine frame from the position of the transfer to the working position in the transverse direction relative to the rail to the border of the ends of the sleepers.

From the patents I8 4614238, I8 4014389 or I8 3151642, the cleaning chains are already known, made as endless, rotating around a rail track for receiving crushed stone. Such chains consist mainly of a transverse section of the chain in contact with the crushed stone bed, and of two articulated longitudinal sections of the chain. Since, in particular, when rearranging the longitudinal section of the chain from the translation position to the working position, there is a danger that the boundary of the profile clearance will be crossed, it will be necessary for safety reasons to close the adjacent rail track adjacent to the work being carried out.

The objective of the claimed invention is the creation of a method of the type indicated above, with which you can reliably translate the longitudinal section of the chain into position.

This problem is solved using the claimed invention due to the characteristics of claim 1 of the claims, namely, that:

a) accumulate in the computing unit the values of the length of the arrow, determining the exact position of the processed rail track;

b) measure the position of the rail in the area of the lifting unit for straightening the track, creating the actual value of the length of the arrow, compare it with the accumulated lengths of the arrow and, if there is a deviation, move the track using the lifting unit for straightening the track to the exact position of the rail due to the accumulated the length of the arrow;

c) control the movement of the longitudinal section of the chain in the longitudinal direction of the rail track for its final lowering to the working position by means of the mechanical connection acting on the limit switch between the lifting unit for straightening the rail track and the longitudinal section of the chain and stop if the clearance profile is exceeded.

Using the inventive method, it seems possible to translate the longitudinal section of the chain into working position without blocking the adjacent section of the rail track. Since when the entire ballast ballast is removed for a short time to clean the ballast, the initial position of the rail track is completely violated, it is especially important to be able to observe the accumulated values of the length of the arrow. Thus, the maximum permissible lateral distance between the lifting unit for straightening the track, which is located according to the accumulated values necessary to restore the original position of the track, and the external contours of the longitudinal section of the chain, is always known exactly. Thanks to the mechanical connection, there is still reliability in that the excess of the clearance profile is reliably excluded also in the event of a failure of the hydraulic components.

Other advantages of the claimed invention are described in the dependent claims and are illustrated in the accompanying drawings.

Further, the claimed invention is described in more detail by the example of its design depicted in the drawing.

In FIG. 1 shows a partial side view of a crushed stone cleaning machine having a cleaning chain; and in FIG. 2 and 3 - a view in the longitudinal direction of the machine or a top view of the detail of the harvesting chain.

In FIG. 1 shows schematically in a simplified form a section through a machine 1 for cleaning crushed stone of a rail track 2, which has a frame 4, supported by running gears 3 on a rail track 2 and moving along it. On this frame there is a cleaning chain 5 for receiving crushed stone of the rail track, a lifting unit 6 for straightening the rail track with the possibility of moving in height and to the side, a working cabin 7, as well as conveyor belts 8 for transporting the removed crushed stone, as well as for dumping cleaned or new crushed stone. Located on the machine frame 4, the harvesting chain 5 with the possibility of translating it using the drive 9 in height and to the side consists of two longitudinal sections 10 and one transverse section 11 and is shown in the drawing in the translation position, while the working position of the cleaning chain 5 the dash is a dashed line.

In the indicated working position (as can be accurately seen in Figs. 2 and 3), intended for receiving crushed stone from the rail track, a transverse section 11 of the harvesting chain 5 is placed under the sleepers 12 of the rail 2, and the longitudinal sections 10 of the chain are respectively relative to the transverse direction 13 rail in a position bordering the ends of 14 sleepers. In order to move the harvesting chain 5 from the translation position to the operating position, the longitudinal sections 10 of the chain must be moved by the drive 9 in the transverse direction 13 of the rail track and then lowered, after which the transverse section 11 of the chain can be installed. In this case, the track 2 will be held by means of a lifting unit 6 for straightening the track in a position in which it will no longer rest on the rubble.

In accordance with the claimed scope of legal protection of the invented method for rearranging the harvesting chain 5, first the lengths of the arrows are accumulated, which determine the exact position of the processed rail track 2, in the computing unit 15 located on the machine 1. This procedure can, for example, be performed as a result of the first preliminary process the measurement performed during the first working movement along the machined rail 2, in which the values of the arrow arrows are determined, which determine the exact position of the rail on the road, and accumulated or thereafter loaded into the computing unit 15.

Subsequently, when the rail is captured by the lifting unit 6 for straightening the track, the actual position of the rail 2 in this area is measured using the sensor connected to it (not shown in the drawing) and the actual values of the arrow length are formed, which correspond to the horizontal distance between the lifting unit 6 for straightenings of a rail track and a frame of 4 cars. The actual values of the length of the arrow are then compared with the accumulated values of the length of the arrow. In the case of deviations caused, for example, by the displacement of the track 2 by the machine 1, the track 2 will be moved using the lifting unit 6 to straighten the track to the exact position of the track due to the accumulated lengths of the arrow.

During the rearrangement process, it is additionally controlled by means of a mechanical connection 16 located between the lifting unit 6 for straightening the rail track and the longitudinal section 10 of the chain, the movement of the longitudinal section 10 of the chain in the transverse direction 13 of the rail as a precaution. For this purpose, the connection 16, made in the form of a chain connection 19, acts on the limit switch 17, which can be placed, for example, on the longitudinal section 10 of the chain and thereby stops the lateral movement of the longitudinal section 10 of the chain as soon as the profile of the lumen 18 of the track 2 may be exceeded in the direction of the adjacent track. Due to this, the movement along the adjacent rail track can also continue during the rearrangement of the harvesting chain 5.

Additionally, to increase reliability or alternatively, a cable connection can be provided connected to the limit switch 17 between the lifting unit 6 for straightening the rail track and the longitudinal section 10 of the chain, which is designed to limit the maximum lateral movement in the working position and acts at the moment when the specified mechanical compound 16.
