The invention relates to the technical field of high-position drilling, in particular to a high-position auxiliary drilling device which comprises a high-position drill floor, a bidirectional lead screw is rotationally connected to the inner bottom wall of the high-position drill floor, a first mounting block is in threaded connection with the outer portion of the bidirectional lead screw, and a lifting frame is hinged to the top of the first mounting block; and the outer part of the first sliding screw rod is slidably connected with a second mounting block. According to the high-position auxiliary drilling device, a lead screw motor is started to drive two bidirectional lead screws, four first mounting blocks are driven to move oppositely or oppositely through symmetrical threaded ring layers of the bidirectional lead screws, at the moment, a lifting frame deforms, a supporting top plate changes in height, then a second hydraulic cylinder is controlled, the second hydraulic cylinder pushes a translation seat to move leftwards, and drilling is completed. The translation seat drives the supporting rod to generate angle change, and then the inclined table is lifted through the supporting rod to be flush with the right side of the top of the high-position drill floor, so that driving safety when the down-the-hole drill goes up and down the high-position drill floor is guaranteed.
本发明涉及高位钻孔技术领域,具体为一种高处辅助钻孔装置,包括高位钻台,所述高位钻台的内底壁转动连接有双向丝杠,所述双向丝杠的外部螺纹连接有第一安装块,所述第一安装块的顶部铰接有升降架,所述第一滑动丝杆的外部滑动连接有第二安装块。该高处辅助钻孔装置,启动丝杆电机驱动两个双向丝杠,通过双向丝杠对称的螺纹圈层带动四个第一安装块相对或相背移动,此时升降架发生变形,支撑顶板进行高度变化,此时再控制第二液压缸,第二液压缸推动平移座向左移动,平移座带动支撑杆发生角度变化,进而通过支撑杆抬升斜面台,使斜面台与高位钻台的顶部右侧平齐,从而保证潜孔钻机上下高位钻台时的驱动安全。
