The invention discloses a good-stability propelling device for geothermal exploration drilling, and relates to the technical field of geothermal exploration, the good-stability propelling device comprises a base station with brake wheels mounted at four corners of the bottom, a rotating motor and two side cavity supporting frames, the diagonal position of the base station is provided with an operation port, the two side cavity supporting frames are fixed on the base station, and the rotating motor is connected with the two side cavity supporting frames. A top plate is jointly and fixedly mounted at the top ends of the two side cavity supporting frames, studs are rotationally mounted in the two side cavity supporting frames, and notches are formed in the sides, close to each other, of the two side cavity supporting frames; the width of the coil spring belt is matched with the width of the notch, when the threaded sleeve rod moves downwards, the coil spring belt on the upper portion can be pulled out, the coil spring belt on the lower portion can be automatically retracted under the action of the coil spring belt, and therefore when the threaded sleeve rod moves, the sealing performance of the notch can be always guaranteed by means of the coil spring belt; and dust generated by drilling is effectively prevented from entering the side cavity supporting frame, so that the stud can be effectively protected.

    本发明公开了一种稳定性好的地热勘探钻孔用推进装置,涉及地热勘探技术领域,包括底部四角安装有带刹轮的基台,所述基台的对角线位置开设有作业通口,还包括旋转电机和两个侧腔撑架,两个所述侧腔撑架均固定在基台上,且两个侧腔撑架的顶端共同固定安装有顶板,两个所述侧腔撑架内均转动安装有螺柱,且两个侧腔撑架相互靠近的一侧均开设有槽口;本发明卷簧带的宽度与槽口的宽度相匹配,当螺纹套杆向下运动时,能够将上方的卷簧带拉出,而下方的卷簧带在自身作用下自动收回,从而当螺纹套杆移动时,能够借助卷簧带始终保证槽口处的密封性,并有效避免钻孔产生的灰尘进入侧腔撑架中,从而能够对螺柱进行有效的防护处理。
