Problems solved by technology
The hydraulic support of the working face is a floating system weakly constrained by the scraper conveyor. During the moving process of the working face, there is a gap between the hydraulic support and the scraper conveyor through pin lugs, resulting in certain errors in the moving process. Some support controller programs are solidified and the control parameters are set to be static, which cannot adapt to the changing geo

Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0037] Please refer to figure 1 , a kind of underground automatic frame moving hydraulic support system of the present invention, the hydraulic support moving detection system includes a hydraulic support, a support controller, a stroke sensor, a pressure sensor, an angle sensor, a height sensor and a pipeline pressure sensor; The coal working face is arranged to support the roof of the working face. At least one pressure sensor is installed on each hydraulic support to measure the support pressure of the roof of the hydraulic support; at least one stroke sensor is installed on each hydraulic support to measure the pressure of each hydraulic support. at least one angle sensor is installed on each hydraulic support to measure the running posture of the hydraulic support during the moving process; at least one height sensor is installed on each hydraulic ...

The invention discloses an automatic support-moving method under a mine and an automatic support-moving type hydraulic support system under the mine. The automatic support-moving type hydraulic support system comprises a hydraulic support pushing detection system, the hydraulic support pushing detection system comprises one or more hydraulic supports, support controllers, pressure sensors, strokesensors, angle sensors and pipeline pressure sensors; the one or more hydraulic supports are arranged along a coal mining work face and used for supporting a work face roof, the support controllers are arranged on all the hydraulic supports, each support controller is connected with the pressure sensor, the stroke sensor, the angle sensor and the pipeline pressure sensor of the corresponding hydraulic support so as to collect the roof support pressure, the pushing stroke, the operation attitude and main pipeline pressure data of the corresponding hydraulic support, and the support controllersautomatically control the support-moving process of the hydraulic supports through a control program. According to the automatic support-moving type hydraulic support system, the column-lowering efficiency of the working face can be improved, the column-lowering process can be stopped while the supports are moved, the supports complete column lowering in the shortest time, the related effect is achieved, the column-lowering time is short, and thus the column-rising time is also short.
Description
technical field [0001] The invention relates to the technical field of intelligent control equipment for hydraulic supports in mines, in particular to an automatic moving method and an automatic moving hydraulic support system in mines. Background technique [0002] The fully mechanized mining face is formed by multiple hydraulic supports arranged in sequence on the working face to realize the support for the roof of the working face and the migration of the scraper conveyor. The hydraulic support of the working face is a floating system weakly constrained by the scraper conveyor. During the moving process of the working face, there is a gap between the hydraulic support and the scraper conveyor through pin lugs, resulting in certain errors in the moving process. Some support controller programs are solidified and the control parameters are set to be static, which cannot adapt to the changing geological conditions of the working face, the equipment and the use environment th...
