Technical Field

The application relates to a large-scale maintenance machinery technology, in particular to a line detection system, a detection method and a tamping car.

Background

The existing tamping car line longitudinal height detection device is composed of B, C, D measuring rods arranged on the left side and the right side of a detection trolley shown in figure 1, two steel strings and two height sensors. As shown in fig. 1, the tips of the measurement rods R and F erected on the detection trolley are tensioned B, D to form a steel string, and the M point of the string passes through the height sensor feeler lever on the C trolley, so that the height deviation value of the C point relative to the BD reference line can be detected.

As shown in fig. 2, the existing tamper vehicle line direction deviation detecting device generally comprises a D, C, B, A four-point trolley mounted on a tamper vehicle, wherein a point D trolley is mounted at the front end of the vehicle, a point a trolley is mounted at the rear end of the vehicle, a tensioned string is connected to the centers of the point D trolley and the point a trolley, vector sensors E1, E2 and A, D are respectively arranged on the point C, B trolley, and the string between the two trolleys passes through the middle of the forks of the sensors E1 and E2, so that when the line direction is deviated at the point B or C trolley, a deviation signal is output on the corresponding sensor. In the prior art, the three-point measurement is performed by using only D, C, B three-point trolley instead of using the A-point trolley, and the principle is similar to that of the four-point measurement, and the description is omitted here.
