Track gangue-blocking device of large dip angle working face hydraulic support

Abstract

一种大倾角工作面液压支架机道挡矸装置,其特征在于:该道挡矸装置包括防护板(2)和防护千斤顶(3),防护千斤顶(3)上端铰接在支架顶梁(1)的一侧,防护板(2)的上端铰接在支架顶梁(1)的另一侧,防护千斤顶(3)的活塞杆与防护板(2)铰接。本实用新型安装在大倾角工作面液压支架上,可以阻挡采煤过程中顶板上空滑落的煤块、矸石等,可以有效维护采煤工作面上方的安全,保护下面机组的安全。从而提高煤矿的生产效率,节省劳动成本。
The utility model discloses a track gangue-blocking device of a large dip angle working face hydraulic support, which is characterized in that the track gangue-blocking device comprises a protective plate (2) and a protective jack (3), wherein the upper end of the protective jack (3) is articulated at one side of a support top beam (1); the upper end of the protective plate (2) is articulated at the other side of the support top beam (1); and a piston rod of the protective jack (3) is articulated with the protective plate (2). The track gangue-blocking device can be arranged on the large dip angle working face hydraulic support, the dropping coal briquettes and gangues above a roof in the coal mining process can be blocked, the safety above the coal face can be effectively maintained and the safety below the unit is protected, thereby improving the production efficiency of the coal mine and saving the labor cost.
