Problems solved by technology
However, in the existing fully mechanized mining face, the shifting frame is not uniform, and the moving step of the working face is difficult to control, which takes up a lot of time. After the two ends of the working face are set, the support cannot guarantee that the hydraulic support, the coal wall and the scraper conveyor will be in the same position after being moved. On a straight line, it is impossible to accurately realize the "three level and straight" of the working face

The invention relates to a thin coal seam hydraulic support system with an alignment device. In the prior art, the fact that a hydraulic support after moving, a coal wall and a scraper conveyer are on the same straight line cannot be guaranteed. Accordingly, the thin coal seam hydraulic support system with the alignment device comprises two end support alignment plates and a plurality of middle support alignment plates. The back portions of the two end support alignment plates are fixed below top beams of working face hydraulic supports at the two ends. The back portions of the middle support alignment plates are fixed below top beams of a middle working face hydraulic support respectively. A pulling rope is arranged between the front portions of the two end support alignment plates. A plurality of alarming devices are included. Each alarming device is arranged close to a middle support alignment plate and comprises two levers, two anti-explosion contact switches, a buzzer and / or an LED lamp. The thin coal seam hydraulic support system has the advantages of being convenient to use, practical, accurate in support locating, three-horizontal-one-vertical feature of a working face is achieved, and the thin coal seam hydraulic support system is suitable for various coal mines and especially suitable for thin coal seam fully-mechanized coal mining.
Description
technical field [0001] The invention relates to a thin coal seam hydraulic support system with a line setting device. Background technique [0002] The working face is required to be "three flat and straight", that is, the three straight lines of the coal wall, the scraper conveyor, and the hydraulic support must be parallel to each other, and the scraper conveyor must be straight. The coal shearer walks on the scraper conveyor, the coal wall is always parallel to the scraper conveyor, and the scraper conveyor is pushed forward by the hydraulic support, so in order to ensure the "three-level and straight" working face, after pulling The hydraulic supports must be in a straight line. However, in the existing fully mechanized mining face, the shifting frame is not uniform, and the moving step of the working face is difficult to control, which takes up a lot of time. After the two ends of the working face are set, the support cannot guarantee that the hydraulic support, the co...
