Description

The present invention relates to an automatic gauge adjusting device .

  Conventionally, the track correction work on the slab track is an inefficient work by manual work, and it is not easy to improve the finishing accuracy. As for the operation of the tamping tool of the current track maintenance machine (branching mulch), twelve tools are moved by operating the operation panel in the vehicle by two people. On the ground, there are one person who instructs the tool position on both sides of the tool, and a total of four people are working only for compaction. Especially at night and in rainy weather, the operator and the instructor are concerned about safety and work mistakes, resulting in a heavy labor.

  The branching martai is a track maintenance machine that mainly works on the railroad track with a roadbed in the branching station and the surrounding roadbed track section. Lines intersect in the vicinity of the branching device and the branching device, and cannot be compacted like a normal parallel line. For this reason, prior to compaction work, we will investigate in advance the position where several people can compact and mark sleepers. And the branching martai comes to the position where it can be compacted with the marks of sleepers, etc., but since the tracks intersect, the vertical direction of the tracks is 6 tools on each side by two operators in the car In the horizontal alignment, the operator in the vehicle aligns according to the instructions of the ground instructor. Then, after both the left and right positions are aligned, the compaction work is performed.

  As a specific example of automating the branching tamping tamping tool, the conventional work as described above is performed, the position at that time is stored in a storage medium such as a floppy (registered trademark), and then the branching machine There is also a device that takes out the floppy (registered trademark) stored at the time of work and reproduces it on the machine with the data. However, the work of compacting the branching device is about once a year, and considering the shape of the branching device, the difference in location, the number of laying of the branching device, etc., the number of data becomes enormous and the data is managed. It is also necessary to consider the method. In addition, the turnout is a place that receives a large impact when passing through the train, and may be partially reworked. If the area around the turnout is reworked, there is a problem that the data stored so far cannot be used and the tool cannot be automatically fixed.

Therefore, by installing a gauge adjustment holding device in the tie, good results can be obtained for the linear maintenance of the tie plate type slab, and by using the data measured in advance, the tool can be automatically set. Since there is no need for an on-ground instructor who is in danger, and only confirmation of the operator in the vehicle is required, early development of a device that contributes to work efficiency, labor saving, safety improvement, etc. is desired.

For reference, the patent literature of the gauge measuring device related to the above-mentioned device filed so far is introduced for reference. (See Patent Document 1.)
