Abstract

A method for drilling holes 4 and / or for attaching fastening devices in these holes 4 for fastening cables in train protection systems on track sections provides a carriage 6 that can be moved on rails 1. This has at least one sensor 7, 7 ′ which responds to the sleeper screw 3 to detect the position of the sleeper 2 to be processed.

Description

The invention relates to a method for drilling holes and / or for attaching fastening devices in these holes for the attachment of cables in train control systems in track sections according to the preamble of claim 1.

Train tracks for train or rail traffic increasingly use train control systems as point-to-point influence PZB and line-train-influencing LZB. All these devices require a signal cable which runs in the track section to be tested in the middle between the two rails of the track.

To attach these cables between the two rails, the sleepers of the track are used. The cables are fastened by means of a corresponding, clip-like fastening device on every second threshold. To attach this fastener on the threshold, it is first necessary that in the threshold from above a hole is drilled. In this hole then the fastening device for the cable is used.

To introduce the holes in the thresholds so far a car is used, which is movable on the rails. The carriage has a drilling device. An operator drives the car to the desired location of the threshold, so that then the bore can be introduced. The disadvantage of this method is that always an operator is necessary to be able to move the car from threshold to threshold and also to operate the drilling device.

Based on this, the object of the invention is to provide an automatic method for drilling holes and / or for attaching fastening devices in these holes for fastening cables in train control systems in the case of track sections.

The technical solution is characterized by the features in the characterizing part of claim 1.

This provides a method of automatically drilling holes and / or automatically attaching fasteners in these holes for attachment of cables to train track protection systems. The basic idea of the invention lies in the fact that the vehicle is equipped with its working equipment with a positioning device using at least one sensor. The carriage moves on the track to be processed independently and finds its own working position, namely drilling position and / or position for introducing the fasteners. By means of the at least one sensor, a contactless detection of the thresholds or of a component of these thresholds is possible. As a result, the movement of the carriage can be derived and controlled with his work equipment and the working position. This positioning method prevents the car from overrunning the target position with its implements, even if the threshold distances are not exactly accurate.

According to the embodiment in claim 2 is preferably used as a sensor, a non-contact sensor, in particular an inductive sensor. This has the advantage that the sensor operates wear-free.

According to the embodiment in claim 3, the threshold screws are used to detect the positions of the thresholds. These sleepers are used to secure the rails to the sleepers. These sleeper screws are made of metal and are therefore ideally suited for the use of inductive sensors.

According to a preferred embodiment in claim 4 seen in the direction of travel, two sensors are used one behind the other. These two sensors move over the sleeper screws with a specific operating distance. The basic principle consists in the fact that the front sensor is first used once for the rough initial recognition of the sleeper screw. This means that the carriage is then moved further at reduced speed until the rear sensor detects the sleeper screw and thus the carriage is in the working position and stops.

The development according to claim 5 proposes a special movement management of the car, in the event that only every second threshold for the attachment of the signal cable is used. The basic principle is that after completion of work at a certain threshold, the car is first accelerated until the next threshold is reached. This next threshold is detected by the sensor. The corresponding signal is used, that the car is now decelerated until the next threshold, namely with respect to the original output threshold, the threshold after next is reached. Thus, there is a sufficient distance to decelerate the car and - especially when using two sensors - clearly locate the next position without overriding this position.

An embodiment for drilling holes for attaching fasteners in these holes for the attachment of cables in train track safety systems will be described below with reference to the drawings. In these shows:

1 a front view of the drill truck;

2 a section along the line AA in 1 ;

3 a detail B from the illustration in 2 ;

4a to 4d the process flow in a plan view;

5 a diagram illustrating the movement sequences.

A rail track for train or rail traffic has two rails 1 which is on sleepers 2 are attached. Threshold screws are used for fastening 3 ,

To be in the middle between the two rails 1 - not shown - to lay signal cables for train protection systems and secure, these cables are on the thresholds 2 fastened by means of corresponding - also not shown - fasteners. These fasteners will be in holes 4 anchored, which is in the middle of the thresholds 2 are located. The attachment of the signal cables on the sleepers 2 takes place on every second threshold 2 ,

For drilling the holes 4 serves a drilling device 5 , This is on a cart 6 attached. This car 6 is on the rails 1 movable by means of a motor drive.

The car 6 has on its one side in succession two inductive sensors 7 . 7 ' on. These sensors 7 . 7 ' are designed to give a signal when they are in the area of the sleeper screws 3 are located.

The operation is as follows:
The starting situation is in 4a shown. In this position is the rear sensor 7 ' in the area of a sleeper screw 3 , In this position of the car 6 has the drilling device 5 previously a hole 4 into the threshold 2 drilled.

In the next but one threshold 2 again a hole 4 to drill, the car is 6 computer-controlled set in motion and accelerated in total with the acceleration a1 until the front sensor 7 a signal from the sleeper screw 3 the next threshold 2 receives ( 4b ).

From this signal is no longer accelerated, but the achieved speed vmax is maintained until the rear sensor 7 ' the sleeper screw 3 passes over ( 4c ).

With this signal of the rear sensor 7 ' the delay a2 becomes active. The car 6 is decelerated up to the specified speed v1. In this position is the front sensor 7 in the area of the sleeper screw 3 , The car 6 maintains this speed v1 until the rear sensor 7 ' from the sleeper screw 3 is switched. This leaves the car 6 standing in the new position ( 4d ). In this, the drilling device 5 a new hole 4 drill. Then the cycle starts again.

The illustrated embodiment describes the drilling of holes 4 , These holes 4 serve to accommodate fastening devices for the cables of the signal line. With the car 6 It is basically equally conceivable, not only by means of the drilling device 5 holes 4 to drill. It is also conceivable, instead (or additionally), the fastening means for the signal lines automatically by means of a corresponding device in the holes 4 contribute.
