矿用液压坑道钻机给进机构
摘要：
本实用新型公开了一种矿用液压坑道钻机给进机构，含有导轨和传动装置，其中：导轨上设置有拖板，二者滑动配合，拖板上端安装有传动装置，拖板侧面安装有传动装置，传动装置含有驱动销齿轮，导轨上设置有销齿排，驱动销齿轮与销齿排相啮合，导轨的端部设置有缓冲装置，拖板上设置有毛刷，本实用新型导轨上安装有机械缓冲装置，用于减少和吸收给进装置停止时的冲击力，且给进拖板上配有毛刷，清除导轨面上煤尘等杂物，同时采用液压传动装置驱动销齿与销齿排啮合运动，实现钻机的给进往复运动，解决了钻机行程销，动力不足，模块化等关键技术问题，大大提高了工作效率。
摘要（英）：

The utility model discloses a feed mechanism of a mining hydraulic underground drill rig. The feed mechanism comprises a guide rail and a transmission device, wherein a carriage is arranged on the guide rail and in slide fit with the guide rail, the transmission device is mounted at the upper end and on the side surface of the carriage and comprises a drive pin tooth gear, a pin tooth row is arranged on the guide rail and meshed with the drive pin tooth gear, a buffer device is arranged at an end part of the guide rail, and a brush is arranged on the carriage. According to the feed mechanism of the mining hydraulic underground drill rig, the mechanical buffer device is mounted on the guide rail and used for reducing and absorbing impact force when the feed device stops, the brush mounted on the feed carriage is used for cleaning sundries such as coal dust and the like on the guide rail surface, meanwhile, the hydraulic transmission device is adopted to drive meshing movement of the pin tooth gear and the pin tooth row, reciprocating feed motion of the drill rig is achieved, key technicalproblems of insufficient power, modularization and the like of a travel pin of the drill rig are solved, and the working efficiency is improved greatly.
