Description

Rail fastening device and method for sectional track repair

Technical Field

The invention relates to a rail fastening arrangement comprising a threaded connection for fastening a connection member to a sleeper, the connection member contacting a rail foot of a rail via a contact element.

The invention also relates to a method for the sectional repair of a track having a rail and sleepers, wherein a group of adjacent sleepers is displaced in the longitudinal direction of the rail such that a construction gap is formed which allows the sleepers to pass through and/or unimpeded ballast cleaning.

Background

From WO 2012095152, a method for segmental repair of a track is known, in which a group of adjacent sleepers is displaced in the longitudinal direction of the rail, so that a construction gap is formed which allows the sleepers to pass through and/or unimpeded ballast cleaning.

Disclosure of Invention

It is an object of the invention to provide a rail fastening arrangement or method of the kind mentioned at the outset, with which the sectional track repair can be simplified.

According to the invention, this object is achieved with a rail fastening arrangement or method of the type specified by the features cited in the characterizing part of the first or second aspect, respectively. According to a first aspect of the invention, a rail fastening device is provided, comprising a threaded connection for fastening a connecting member to a sleeper, the connecting member contacting a rail foot of a rail by means of a contact element, characterized in that the contact element of the connecting member is designed as a rolling body which is rotatable about an axis for rolling on the rail in the longitudinal direction thereof, wherein a clamping device is arranged on the connecting member for establishing a force-locking connection between the connecting member and the rail foot. According to a second aspect of the invention, a method for the segmental restoration of a track having rails and sleepers is provided, wherein a set of adjacent sleepers is displaced in the longitudinal direction of the rail by means of a rail fastening device according to the first aspect such that a construction gap is formed which allows the sleepers to pass through and/or unimpeded ballast cleaning, characterized in that, in order to simplify the displacement of the sleepers relative to both rails, the original rail fastening device is removed and replaced instead with a rail fastening device which can be rolled over the rail in the longitudinal direction of the rail, wherein after the displacement of the sleepers are connected to the rail in a force-locking manner by operation of the clamping device.

Other advantages of the present invention will become apparent from the following aspects. The free end of the connecting member, which is arranged at a position above the rail foot, is arranged centrally between two rolling bodies, which are provided for rolling on the rail foot. The rail fastening devices of a group of sleepers, each associated with one sleeper, are connected to one another by means of a length-adjustable connecting element, wherein the length of the connecting element arranged between adjacent sleepers is configured to correspond to the sleeper distance of the rail. The connecting element is a chain. In order to displace the sleepers again, the sleepers adjacent to the constructional gap are grasped and the sleepers are moved back into their initial position, wherein the rail fastening devices of a group of sleepers, which are each associated with a sleeper, are connected to one another by means of a length-adjustable connecting element, and wherein the adjacent sleepers of the group, which are connected to one another by means of the connecting element, are automatically pulled together into their respective initial position.

Drawings

The invention will be described in more detail hereinafter with reference to an embodiment shown in the drawings.

Fig. 1 shows a view of two rail fastening devices connecting a sleeper to a rail in the longitudinal direction of the rail;

figure 2 shows a top view of two rail fastening arrangements; and

fig. 3 and 4 each show a simplified side view of a track.

Detailed Description

The sleeper 1 visible in fig. 1 and 2 is connected to a rail 3 by means of specially designed rail fastening means 2. For the sake of simplicity, only one rail 3 of the track 4 is shown here. A second rail 3 (not shown) of the track 4 is also connected to the sleeper 1 by two such rail fastening devices 2.

Each rail fastening device 2 comprises a threaded connection 5 for fastening a connection member 8 to the sleeper 1, said connection member 8 contacting the rail foot 7 of the rail 3 via a contact element 6. The contact elements 6 of the connecting member 8 are designed as rolling bodies 10, which rolling bodies 10 are rotatable about an axis 9 for rolling on the rail 3 in the longitudinal direction 11 of the rail. The threaded connector 5 is secured in a hole in the tie 1 which is typically used to secure one of many known rail fasteners.

As can be seen in particular in fig. 2, the free end 12 of the connecting element 8, which is arranged at a position above the rail foot 7, is arranged centrally between two rolling bodies 10, which rolling bodies 10 are provided for rolling on the rail foot 7. At the free end 12 of the connecting member 8, a clamping device 13 is arranged for establishing a force-locking connection between the connecting member 8 and the rail foot 7. The clamping device 13, which is designed here as a screw, for example, can also be configured as an eccentric or the like.

As shown in fig. 3 and 4, the rail fastening devices 2 of a group of adjacent sleepers 1, each associated with one rail 3, are connected to each other by means of a length-adjustable connecting element 14, the connecting element 14 preferably being a chain. The length l of the connecting element 14 arranged between the rail fastening devices 2 of two adjacent sleepers 1 is configured to correspond to the sleeper distance of the rail 4. For example, the connecting element 14 may also optionally be designed to be telescopically extendable.

For the sectional repair of the rail 4, a group of adjacent sleepers 1 is displaced in the longitudinal direction 11 of the rail, so that a constructional gap 15 is formed, which constructional gap 15 allows the sleepers 1 to pass through and/or allows unimpeded ballast cleaning (see fig. 3). In order to simplify the displacement of the sleeper 1 relative to the two rails 3, the original rail fastening device is removed and optionally replaced with the rail fastening device 2 described in fig. 1 and 2. Now, the rail fastening devices 2 together with the associated sleepers 1 can be very easily rolled or displaced by hand on the rail 3 in the longitudinal direction of the rail by the operator to thereby create the constructional gap 15 (see fig. 4) required for track repair. After the sleeper displacement, the sleeper 1 can, if required, be connected to the rail 3 in a force-locking manner by operating the clamping device 13, which is designed as a screw element, in order thereby reliably to prevent any further undesired displacement.

Since only a short time frame is available for track repair due to a more concentrated travel on the track 4, in a possible application cited here by way of example, the sleeper 1 connected to the rail fastening device 2 according to the invention is moved back again into its initial position (see fig. 4) after cleaning of the ballast stored in the construction gap 15. Until the next day, the sleepers 1 are replaced in a further repair phase, wherein, as already mentioned, the required constructional play 15 of the sleeper now passing through is again produced by the displacement of a group of sleepers 1.

For the aforementioned re-displacement of the sleepers 1, it is particularly advantageous if two adjacent sleepers 1 are each coupled by a connecting element 14 (preferably designed as a chain). It is then only necessary to grasp the sleeper 1 adjacent to the constructional gap 15 and move it back into its initial position. Since the rolling resistance is rather low as a result of the rolling bodies 10, said displacement can be performed manually by the operator without any problem. A group of adjacent sleepers 1 connected to each other by means of the connecting elements 14 is automatically pulled into their respective initial positions. Since the length l of each connecting element 14 is adapted to the tie distance, it is ensured that the correct tie distance is likewise automatically achieved with a renewed displacement of the tie 1.
