Description

System and method for measuring falling road quantity of ballast cleaning vehicle and electronic equipment

Technical Field

The application relates to the technical field of railway maintenance machinery design and manufacture, in particular to a falling road quantity measuring system, a measuring method and electronic equipment of a railway ballast cleaning vehicle.

Background

The sleeper ballast screen scarifier needs to control a certain falling path amount in the screening operation, and favorable line conditions are provided for carrying out tamping track lifting and restoring line geometric parameters for the subsequent tamping vehicle.

The existing screening vehicles used at home and abroad all adopt open loop control to control the falling road quantity, namely: the falling channel quantity H can be set in the control, but whether the required falling channel quantity H can be achieved or not is judged, a measuring system without feedback is provided, and a corresponding feedback control mechanism is provided; in this control method, it is generally necessary to make a manual measurement after that and to add a corrected falling track amount Δh so that h+Δh approaches the actual falling track amount.

However, due to the different types of existing rails and sleepers, and dynamic changes in line conditions and line geometry, ΔH requires frequent updates to accommodate such changes, which is not easily achievable in construction. Normally, only one H is set, a larger falling path error is allowed after screening, and the correction quantity delta H is added when the falling path quantity deviates greatly through manual measurement.

Based on the dilemma, it is necessary to develop a system and a method for monitoring the falling track quantity in real time and performing closed-loop control to improve the backfilling quality of the ballast after screening, reduce the labor intensity, provide more favorable line conditions for the subsequent tamping vehicle to carry out tamping and track lifting and recover the line geometry, and further improve the operation efficiency of the whole screening machine set.
