The invention relates to the technical field of shaft monitoring, in particular to a full-stroke monitoring device for a coal mine shaft, which comprises a cage, the side wall of the cage is provided with an offset detection mechanism, and the inner center of the cage is provided with a counterweight correction mechanism; the deviation detection mechanism comprises a plurality of fixing sleeves fixedly connected to the side wall of the cage, first rotating shafts are arranged on the inner sides of the tops and the bottoms of the fixing sleeves correspondingly, first limiting wheels are rotationally installed on the outer sides of the first rotating shafts, and inclined guide rails are arranged on the front sides and the rear sides of the first rotating shafts correspondingly. The counterweight correction mechanism comprises an elliptical rail arranged in the center of the interior of the cage. Real-time detection of the deviation angle in the downward moving process of the cage is achieved through the deviation detection mechanism, meanwhile, when the cage inclines and deviates, a first limiting wheel is driven to obliquely slide along the interior of an oblique guide rail, then a conductive contact piece and a conductive block are in contact and powered on, accurate detection of the inclination angle is achieved, and the detection efficiency is improved. And the response speed between operation is improved, and the risk is effectively reduced.
本发明涉及井筒监控技术领域,尤其涉及一种用于煤矿井筒的全行程监控设备,包括罐笼,所述罐笼的侧壁设有偏移检测机构,所述罐笼的内部中心设有配重校正机构;所述偏移检测机构包括固定连接在罐笼侧壁的多个固定套,所述固定套的顶部和底部内侧均设有第一转轴,所述第一转轴的外侧转动安装有第一限位轮,所述第一转轴的前后侧均设有斜向导轨;所述配重校正机构包括设置在罐笼内部中心的椭圆轨。本发明通过偏移检测机构实现对罐笼下移过程中偏移角度的实时检测,同时通过罐笼发生倾斜偏移时带动第一限位轮沿斜向导轨内部倾斜滑动,进而使得导电触片和导电块接触通电,达到了对倾斜角度的精准检测,提高操作间的响应速度,有效降低的风险。
