Description

DETAILED DESCRIPTION OF THE INVENTION The present invention moves on the rails of a track, corrects daylight, level, and misalignment of the track, and uses a tamping device to compact the track bed ballast on the lower surface of the sleeper at the corrected position. The present invention relates to a level correction device for a track straightening machine that corrects the level of the track, that is, corrects the level and cant of the track.

Conventionally, the leveling device of a track straightening machine uses one rail as a reference rail in the left and right rails of the track, and adjusts the level of the other rail (including cant) with respect to this reference rail.
is detected, and this detected value is compared with a preset set value, and if the two are not equal, the other rail is raised relative to the reference rail, and the detected value and the set value are adjusted. The level of the orbit was adjusted so that they were equal. However, with the leveling device of this conventional track straightening machine, it is possible to correct the track level to a preset value, but after leveling, the tamping device removes the trackbed ballast from the lower surface of the sleeper at the corrected position. After tamping and straightening the track, it is possible to correct for the drop in the rail or the overburden.If necessary, the operator can use experience and feeling to take into account the condition of the track bed. In anticipation of the rail falling or overpaying after track alignment, the rail must be lifted and the track level adjusted.

The drawback was that it was not possible to make reasonable adjustments to the level of the orbit in accordance with the condition of the orbit.

The present invention has been made to eliminate the above-mentioned drawbacks, and detects a drop in the level of a pre-adjusted trajectory or an overpayment, and calculates a correction error based on the difference between this detected value and a preset setting value. A correction setting value is obtained from the algebraic sum of this correction error value and the level setting value, and this correction setting value and the water/v! of the position where the level of the trajectory should be corrected! A level correction device for a track straightening machine that can correct the track level according to the track condition by comparing the detected values and lifting the other rail with respect to the reference rail so that the two are equal.
