DEVICE FOR INDEPENDENT CONTROL OF POWER SUPPLY OF ACTUATORS FOR SUSPENSION AND LIFTING OF RAIL AND SLEEPERS Russian patent published in 2024 - IPC E01B27/17 H02P11/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to railway transport for providing power and control of lifting and hanging mechanisms of rail-and-sleeper grid using track machines of cyclic and continuous-cyclic action. Device for independent control of power supply of actuating mechanisms of suspension and lifting of rail and sleepers includes a module of input voltage converter, an optoelectronic decoupling module, a status indication module, modules for generating a control signal of the lifting drives of the right and left grippers of the lifting-and-straightening device (LSD). Module for generating the control signal of the drives for lifting the right block of LSD grippers includes a source-stabilizer of reference voltages A, a primary cascade for generating a signal A₁, a secondary cascade for generating a signal A₂, a relay switch A₁, a relay switch A_2. Module for generating the control signal of the drives for lifting the left block of the LSD grippers includes a source-stabilizer of reference voltages B, a primary cascade for generating signal B₁, a secondary cascade for generating signal B₂, a relay switch B₁, a relay switch B₂.

EFFECT: expansion of functional capabilities of device for independent control of power supply of actuators of suspension and lifting of rail-and-sleeper grid due to provision of parallel independent control of lifting of right and left threads of longitudinal profile of rail-sleeper grid, which allows controlling the bending boom in the vertical plane along the axis of the track in order to provide the specified mode of hanging and lifting the rail-and-sleeper grid.
