         Rope winder, petroleum instrument salvaging system
         and petroleum instrument hoisting system
         Pat. 10,087,054 U.S. class B66D 1/485 Int. Class E21B 23/14
         Inventor: Biao Yang, Beijing, CN.
         Assignee: Beijing Hailan Science & Technology Development
         Co., Ltd., Beijing, CN.
           This patent presents a rope winder, which has a rack, and
         a winding drum set on the rack that releases and retracts a
         rope. The rope includes a first turning wheel, an electron-
         ic counter, a calculating unit, a speed regulating unit and
         a  control  unit. The turning wheel has a  groove  which fits
         the rope. A petroleum instrument salvaging system which
         includes the rope winder and rope. One end of the rope is
         wound on the winding drum of the rope winder. A petroleum
         instrument hoisting system which includes the rope winder
         and a rope of which one end is wound on a winding drum of
         the rope winder.
           One embodiment of the invention provides a rope winder,
         for salvaging or hoisting a petroleum instrument via a rope
         3. Specifically, the rope winder provided is used for manip-

                                                              of a petroleum instrument salvaging system or the hoisting
                                                              head of a petroleum instrument hoisting system. Referring
