FIELD: physics.
SUBSTANCE: invention relates to general-purpose pneumohydraulic systems and more specifically to drive of unloading-dosing devices for ballast laying on railway track by special rolling stock during construction and repair of railway track. Driving control of dosed discharge of ballast on railway track comprises working pneumatic line, connected via disconnecting valves to locomotive supply main line, with unloading-dosing devices of special rolling stock and more specifically hopper-batcher, namely: hopper covers installed on rotary shaft, and batcher suspended under hopper on four mechanical rods installed after disconnecting valve of pneumatic-hydraulic converter with control elements, connected to hydraulic distributors unit, connected by hydraulic lines to power hydraulic motors, each of which is mechanically connected to dispenser, hopper covers and a position monitoring device connected to the hydraulic distributor unit control device. At that, control device may be included in computation system of track works planning and control.
EFFECT: technical result is reduction of weight and dimensions of drive mechanisms, higher accuracy of positioning and optimization of power consumption and optimization of operating modes with possibility of implementing digital control methods, reduced weight and dimensions of drive mechanisms, higher accuracy of positioning and optimization of power consumption and optimization of operating modes with possibility of implementing digital control methods, reduced weight and dimensions of drive mechanisms, higher accuracy of positioning and optimization of power consumption and optimization of operating modes with possibility of implementing digital control methods.
