The invention discloses an underground coal mine deep hole logging instrument, which belongs to the technical field of logging instruments and comprises a logging instrument body, a bottom buffer mechanism is arranged at the lower end of the logging instrument body, a lifting rope is mounted at the upper end of the logging instrument body, a lifting rope limiting mechanism is mounted at the upper end of the lifting rope, and a fixing cylinder is arranged on the surface of the logging instrument body. The lifting rope limiting mechanism is arranged, the lifting rope can be conveniently wound and unwound through the lifting rope limiting mechanism, so that the logging instrument can be downwards lifted into coal mine wells with different depths so as to monitor the coal mine wells with different depths, the lifting rope limiting mechanism can adjust the unwinding position of the lifting rope through the limiting assembly, and the lifting rope can be conveniently wound and unwound through the lifting rope limiting mechanism. The stability of the logging instrument in the descending process is guaranteed, it is guaranteed that the logging instrument can be located in the center of a coal mine well all the time, and meanwhile the position of the logging instrument can be adjusted so that the logging instrument can avoid protruding stones on the well wall.

    本发明公开了一种煤矿井下深孔测井仪,属于测井仪技术领域,包括测井仪本体,所述测井仪本体的下端设置有底部缓冲机构,测井仪本体的上端安装有吊绳,吊绳的上端安装有吊绳限位机构,测井仪本体的表面设置有固定筒,本发明通过设置了吊绳限位机构,该机构可以便于对吊绳进行收放卷工作,从而能够将测井仪能够下升至不同深度的煤矿井的内部,以便对不同深度的煤矿井进行监测,本发明通过设置了限位组件,该机构可以对吊绳的放线位置进行调节,以保证测井仪下降时的稳定性,保证其能够一直处于煤矿井的中心位置,同时,也可以对测井仪的位置进行调节,使其能够避开井壁凸起的石头。
