The limitations that the elevation of a rail surface during traditional artificial rail lifting of a railway, and rail lifting amount cannot be subjected to datamation are broken through.

Description

technical field [0001] The invention belongs to the technical field of instrumentation analysis and measurement control, and in particular relates to a laser control device for artificial railway elevation elevation and an elevation control method thereof. Background technique [0002] Ballasted railway lines are often caused by local subsidence of the ballast bed and roadbed, resulting in uneven line heights, affecting the normal operation of trains, and even endangering traffic safety. Therefore, it is necessary for the railway engineering unit to carry out lifting and tamping operations on the sinking section of the line according to the unevenness of the line. Among them, the lifting is to lift the track surface of the ballasted track potholes and sinking places to increase the thickness of the lower ballast bed ;Tamping is to compact and tamp the increased ballast bed, thereby increasing the supporting force of the ballast bed; and then adjust the longitudinal section t...

AI Technical Summary

Problems solved by technology

[0004] (1) At present, when the railway works department conducts manual lifting operations on ballasted lines, the smoothness of the line and the amount of lifting mainly rely on experienced masters who lie on the rails and use their eyes to estimate. There is no special measuring instrument during the lifting process To control the lifting amount, the lifting effect is only based on experience, the lifting height cannot be digitized, and there is a lack of data support and scientific guidance

Because purely relying on personnel estimates is greatly affected by human factors and environmental factors, this traditional lifting control method leads to inaccurate lifting volume, poor renovation effect, and sometimes even aggravates the original level of the line.

[0005] (2) Due to the limited field of view in the existing manual lifting method, it is impossible to control the flooding pit (long-distance unevenness of the line) as a whole. Line shape; for example, when working at night, due to the dark light, the eyes will be inaccurate, and the quality of the renovation will often fail to achieve the expected effect

[0006] (3) The existing ballast line elevation measuring instruments are mainly level instruments (electronic, optical), and the matching tripods and tower rulers are heavy and inconvenient to erect and carry the equipment

In addition, the tower ruler cannot be fixed on the rail surface, and it is difficult to ensure that it is perpendicular to the horizontal plane in real time by relying on manual support during the lifting process, which affects the measurement accuracy; and the standing position of the ruler holder affects the normal operation of the press hand

[0007] It can be seen that the current artificial lifting method mainly relies on human eye estimation, and the operation method is backward. It has disadvantages such as unquantifiable lifting amount, limited observation range, difficult night operation, and laborious observation.
