Technical Field
The invention relates to the field of railway engineering machinery, in particular to a control method of a screen cleaning/ballast throwing conversion controller for track screen cleaning.
Background
The screen scarifier for railway line maintenance can realize two operations of continuous screen scarfing and continuous ballast throwing, an operator can select a screen scarfing working condition and a ballast throwing working condition through a screen scarfing/ballast throwing button on an operation panel, and the conversion of the screen scarfing working condition and the ballast throwing working condition is realized through a ballast throwing device on a ballast mixing conveying device. When the ballast throwing working condition is adopted, the ballast separating plate moves backwards, the dirty ballast mixing plate directly falls to the dirty soil conveying device, and the dirty ballast is thrown to one side of the line or conveyed to the material transport vehicle through the rotary conveying device. And when the working condition of cleaning the screen is carried out, the ballast separating plate moves forwards, the dirty mixed ballast is conveyed to the vibrating screen for screening, and the screened clean railway ballast is directly thrown down on the line through the backfilling ballast dropping hopper. During the screen cleaning operation, when emergency shutdown is met, all mechanisms still operate, and the screened clean railway ballast is automatically backfilled and thrown down on a circuit to form a backfilled railway ballast stacking package, so that a screen cleaning fault is generated. In order to solve the screen cleaning fault of emergency shutdown of the screen cleaning machine, the cooperative actions of stopping screen cleaning and backfilling and starting to throw the ballast and convey the ballast are required to be implemented, and the dirty and mixed ballast is directly thrown to one side of a line or conveyed to a material transport vehicle.
Disclosure of Invention

S101: and (3) replacing the ballast throwing working condition: the approach switch of the mixed ballast dividing plate senses that the mixed ballast dividing plate is in a rear-end ballast throwing working condition, the display gives a prompt for converting the cleaning working condition into a ballast throwing working condition, the mixed ballast is directly conveyed away by the material vehicle without being subjected to cleaning and backfilling, and the replacement of the ballast throwing working condition is realized.
S102: resetting the cleaning working condition: after the screen scarifier re-runs, when the speed encoder detects that the vehicle speed is greater than zero, the time is delayed for several seconds, the longitudinal moving oil cylinder drives the mixed ballast dividing plate 7 to move forwards, the mixed ballast dividing plate approach switch senses that the mixed ballast dividing plate is in a front-end ballast throwing working condition, the display gives a state prompt that the ballast throwing working condition is converted into a screen scarfing working condition, dirty mixed ballasts are conveyed to the vibrating screen for screening, screened clean ballasts are directly thrown onto a line through the backfilling ballast dropping hopper, the screen scarfing working condition is reset, and the normal screen scarfing working condition is recovered.
S103: and (3) converting the working conditions of screen cleaning/ballast throwing: when the screen scarifier meets the S100 condition, the loop of the S100 to S102 program is entered again.
The beneficial technical effects of the invention are as follows: because the algorithm controller is arranged in the control display system, the conversion of the cleaning/throwing working condition, the transposition of the throwing working condition and the resetting of the cleaning working condition can be realized according to the program. Meanwhile, the mixed ballast dividing plate and the mixed ballast dividing plate proximity switch are arranged in the screen scarifier, so that the position state of the mixed ballast dividing plate can be sensed by the mixed ballast dividing plate proximity switch, and the identification and conversion of the screen scarifier/ballast throwing working condition are realized. The invention also has the advantages of simple method, effective control, timely response and convenient maintenance.
