MINING MACHINE LIFTING CONTROL SYSTEM, METHOD AND DEVICE, MINING MACHINE AND MACHINE-READABLE DATA MEDIUM Russian patent published in 2025 - IPC E21F13/00 E21D9/13 

FIELD: mining; vehicles in general.

SUBSTANCE: group of inventions relates to a system, a method and a device for controlling the lifting of a mining machine, a mining machine and a machine-readable data medium and relates to the technical field of vehicle control. Proposed system for controlling the lifting of a mining machine comprises controller, lifting solenoid valve circuit connected to cargo container, lowering solenoid valve circuit and floating solenoid valve circuit. Controller is connected to the lifting solenoid valve circuit, the lowering solenoid valve circuit and the floating solenoid valve circuit. Controller is configured to control the actuation of the lifting solenoid valve circuit after receiving the lifting signal command. Lift solenoid valve circuit is configured to lift the cargo container from the first current position to the first preset position in the on state. Controller is additionally configured to control the actuation of the floating solenoid valve circuit or to control the actuation of the lowering solenoid valve circuit and the floating solenoid valve circuit after receiving the lowering signal command. Lowering solenoid valve circuit is configured to lower the cargo container from the second current position to the second preset position in the on state, and the floating solenoid valve circuit is configured to lower the cargo container from the second predetermined position to the third predetermined position in the on state or to lower the freight container from the second current position to the third predetermined position in the on state. Circuit of floating solenoid valve is configured to control delayed lowering of cargo container on frame under action of own gravity of cargo container. First predetermined position is the highest vertical position installed by the freight container, third predetermined position is the lowest vertical position set by the cargo container, second predetermined position is lower than the first predetermined position and higher than the third predetermined position, first current position is any position other than the first preset position, and the second current position is any position above the second preset position.

EFFECT: reduced impact between cargo container and frame and longer service life of hydraulic components.
