Description

Technical Field

[0001] The present application relates to the technical field of railway track ballast line maintenance, and in particular to a method and device for detecting the amount of track drop during the operation of a ballast bed cleaning and screening machine. Background Art

[0002] At present, in the operation of large-scale road maintenance machinery roadbed cleaning and screening machines, the track drop (sinking) after cleaning needs to be manually detected. The existing methods for detecting the drop are:

[0003] 1) Using trackside fixed facilities as reference points, such as adjacent line sleepers, trackside poles, etc., to detect, record and indicate the relative height of the line before operation;

[0004] 2) At the reference point (the detection point is relative to the same reference object before the operation), detect the relative height of the line after the operation;

[0005] 3) The amount of track fall on the operation line is characterized by comparing the height difference before and after the operation.

[0006] The workload of manual measurement is large, the density of detection points is low, and when the adjacent line is open to traffic, there are major safety hazards.

[0007] In the prior art, such as patent CN203065910U, angle sensors are installed on the lower surfaces of the crossbeams on the front bogie and the rear bogie to achieve the purpose of real-time measurement of the longitudinal height difference of the rail surface; however, in actual screening operations, since the frame is relatively soft, the frame may bend and deform during the operation, which has a great impact on the detection accuracy and cannot accurately reflect the actual amount of track drop.

[0008] In addition, since the middle working area of ​​the screen cleaning machine exceeds the width of the frame and the bottom of the frame is affected by backfill, the laser or steel string technology cannot penetrate the straight line distance between the two bogies. Therefore, the direct measurement method of the steel string and the indirect measurement method of the laser are relatively difficult.

[0009] However, it is very necessary to accurately detect the amount of falling track after the cleaning operation in practical applications;

[0010] 1) It can be passed to the following tamping vehicle as reference data for subsequent tamping vehicle operations;

[0011] 2) Provide post-operation feedback on the excavation depth of the cleaning operation to facilitate real-time adjustments in excavation or backfilling operations and improve the quality of line operations.

[0012] Therefore, a method that can accurately detect the amount of roadbed cleaning machine falling on the track is particularly important. Summary of the invention
