Abstract

The invention provides a posture self-adaptive regulation and control system and method for a hydraulic support. The posture self-adaptive regulation and control system comprises the hydraulic support and a posture regulation and control jack arranged on the hydraulic support. The supporting state monitoring device is arranged on the hydraulic support and collects attitude information of the hydraulic support in real time when the hydraulic support is in a bearing state; the calculation device is in communication connection with the support state monitoring device, determines the support posture of the hydraulic support according to the posture information and generates a regulation and control strategy of a posture regulation and control jack according to the support posture; and the electro-hydraulic controller is arranged on the hydraulic support, is respectively connected with the posture regulation and control jack and the calculation device, and is used for controlling the extension length of the posture regulation and control jack according to the regulation and control strategy so as to regulate the hydraulic support to a preset posture. Therefore, when the hydraulic support is in a bearing state, the support posture of the hydraulic support can be adjusted in a self-adaptive mode, and therefore it is guaranteed that the hydraulic support is in a better stress state.

Description

technical field [0001] The application relates to the technical field of working attitude control of hydraulic supports in coal mine fully mechanized mining face, in particular to an attitude self-adaptive control system and control method of hydraulic supports. Background technique [0002] Hydraulic support, as one of the main equipment of the fully mechanized mining face, provides a safe working space for the normal production of the working face. At the same time, during the recovery process, the hydraulic support cooperates with equipment such as coal shearers and scraper conveyors to realize continuous advancement and efficient production of the working face. The hydraulic support is mainly used to support the roof of the working face and bear the mine pressure of the working face, and the quality of the working posture during its operation determines the stress state of the hydraulic support. [0003] At present, the hydraulic support mostly adopts a two-column cover...
