Self-adaptive leveling method and device of hydraulic support top beam

Abstract

The invention discloses a self-adaptive leveling method and device of a hydraulic support top beam. A main controller monitoring the numerical value of a tilt sensor in real time and feeding results back to a hydraulic support electro-hydraulic system is adopted in the process that a support is controlled by the hydraulic support electro-hydraulic system to lift a column, real-time adjustment is carried out by the main controller according to the angle of tilt of the top beam, a jack starts to be adjusted and balanced when setting load is applied by the stand column, a blind-action probing method is adopted, the value of the tilt sensor is monitored in real time in the motion probing process so as to detect the state of the top beam, and when the numerical value of the tilt sensor is within a top beam balance error range, leveling is completed. By means of the self-adaptive leveling method and device, automatic leveling control of the hydraulic support top beam can be achieved under the existing automatic batch control and automatic machine following control modes on the premise that an existing mechanical hydraulic equipment structure is not changed.

Description

technical field [0001] The invention relates to an electro-hydraulic control system of a hydraulic support, in particular to a method and device for self-adaptive leveling of a top beam of a hydraulic support. Background technique [0002] At present, the existing hydraulic support system cannot realize automatic control well when the top beam is leveled. In the existing control method, the leveling is only realized in the single-frame hydraulic support control mode, but the automatic leveling cannot be realized. It still relies on manual control of the expansion and contraction of the balance cylinder to achieve the purpose of leveling the top beam. That is, under the existing automatic follow-up mode and group automatic control mode, and without changing the mechanical structure of the existing hydraulic valve, adaptive leveling cannot be realized. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention ...
