The invention discloses a cable self-tensioning type logging truck which comprises a cable winch installed on an installation frame of a logging truck body, a cable sequentially penetrates through a cable dredging mechanism, a guide pulley, a tightening mechanism and a pneumatic tensioning mechanism and extends into a well, the pneumatic tensioning mechanism is arranged at a well mouth and seals the well mouth, and the cable winch is installed on the installation frame of the logging truck body. The pneumatic tensioning mechanism is communicated with a bypass pipe, the cable dredging mechanism, the guide pulley and the tightening mechanism are all connected with the mounting frame, and a vertical hydraulic cylinder is arranged between the tightening mechanism and the pneumatic tensioning mechanism. According to the invention, when the logging equipment is put into a well, the cable connected with the logging equipment is always kept in a tensioned state, so that the phenomena of winding and knotting caused by over-looseness of the cable are avoided, a well mouth is effectively sealed, and pollution to equipment on the well due to overflowing of pressure liquid in the well is avoided; in the process of recycling the cable, sundries such as sludge on the cable are effectively removed, and the service life of the cable is prolonged. The invention is suitable for the technical field of logging trucks in geological logging.

    本发明公开了一种线缆自张紧式测井车,包括安装于测井车车体的安装车架上的线缆卷扬机,线缆依次穿经线缆清淤机构、导向滑轮、束紧机构及气动张紧机构并伸入到井内,气动张紧机构设置于井口处并封闭井口,气动张紧机构连通有旁通管,线缆清淤机构、导向滑轮及束紧机构均与安装车架连接,于束紧机构和气动张紧机构之间设置有竖向液压缸。本发明确保了测井设备在下放入井内的过程中,与测井设备连接的线缆始终保持张紧的状态,避免了线缆过松而出现缠绕、打结的现象,有效地封闭井口,避免了井内压力液体冒出而污染井上设备;在回收线缆的过程中,有效地去除线缆上的淤泥等杂物,提高了线缆的使用寿命。本发明适用于地质测井中测井车的技术领域。
