Abstract

The invention discloses a hydraulic support comprising a top beam and a beam detecting mechanism connected to the top beam. The beam detecting mechanism comprises a front detecting beam, a telescopic beam and a telescopic beam driving mechanism, wherein the front detecting beam is fixedly connected on the wall surface, opposite to a support surface, of the top beam; the telescopic beam is slidably connected to the front detecting beam; and one end of the telescopic beam driving mechanism is connected to the front detecting beam, and the other end of the telescopic beam driving mechanism is connected to the telescopic beam. By arranging the beam detecting mechanism at the lower end of a top beam of an existing hydraulic support, lower coal layer or rocker layer can be supported by the beam detecting mechanism, exploration of the complicated coal layer by layering is realized, mixing of coal and rock during coal exploration is avoided, subsequent coal separating steps are omitted, production efficiency is improved and work intensity is reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a hydraulic support. Background technique [0002] As a supporting equipment, hydraulic supports are widely used in fully mechanized coal mining. The hydraulic support generally includes parts such as the side guard and the top beam. The side guard and the top beam are hinged, and the jack is connected between the side guard and the top beam. Features. [0003] At present, the existing hydraulic support only has a top beam mechanism, which determines that the use of the existing hydraulic support can only achieve one coal mining operation, and complex coal seams cannot be mined in layers. Under certain specific geological conditions, for example, the geological conditions of a certain coal mine are that the thickness of the coal seam is 3.2 meters, there are 1.2 to 2.1 meters of uneven gangue in the middle, the upper coal seam is 0.4 meters, and the lower coal seam is 0.55 ...
