Description

Railway circuit triangular pit alarm device based on tamping car

Technical Field

The utility model belongs to the technical field of railway road maintaining machinery and specifically relates to relate to tamping car field.

Background

The tamping car is used in the construction of new lines of railway lines, the cleaning of old lines and the maintenance of existing lines, and can carry out the operations of lifting and leveling, shifting, tamping stone ballast and tamping shoulder stone ballast on tracks. After operation, the direction, the left and right level, the front and back height of the track can meet the requirements of line design standards or line maintenance rules, the compactness of the railway ballast can be improved, the stability of the track is enhanced, and the safe operation of the train is ensured. The operation object of the tamping car is a track bed, and the horizontal and directional deviation of the railway line is eliminated by adjusting the track bed. According to the railway track maintenance rules, the track after the operation of the tamping car is allowed to have horizontal deviation. However, if the left strand rail is higher than the right strand rail and the right strand rail is higher than the left strand rail within a short distance, and the distance between the two maximum horizontal error points is less than 18m, the horizontal error is called a triangular pit. A triangular pit with a level difference of more than 4mm will suspend one of the four wheels of the vehicle bogie. If the greatest transverse force occurs exactly on this wheel, it is possible for the wheel to climb the rail and a derailment accident to occur. So that no triangular pits are allowed on the railway line. In order to meet the operation requirement, the tamping car is provided with the measuring trolley, the measuring trolley is provided with the measuring device, the line level and direction data before and after line operation can be measured, and whether a triangular pit exists in the line cannot be detected.
