The invention relates to an offshore well power assisting device, in particular to an offshore well power assisting device with chromium and manganese alloy welding springs. The upper hole end of a welding spring buffer is connected to each platform hinge of an operation platform, and the lower hole end of each welding spring buffer is connected and fixed to a fixing supporting leg. A well drilling swing rod is rotationally fixed to a swing rod shaft pin on a swing rod base, a large well drilling rope is fixedly connected with one side end of the well drilling swing rod, and the large well drilling rope penetrates through a platform drilling hole in the operation platform and then goes deep to a seabed oil well bed. The offshore well power assisting device is characterized in that an isolation component is arranged on a front end cover in a squirrel cage type flameproof triangular belt wheel motor, all the bending moment loads are shared, a motor rotating shaft is made to only bear pure torque, the squirrel cage type flameproof triangular belt wheel motor and the welding spring buffers are combined together through the operation platform, meanwhile, the two problems, namely the power source motor rapid wear problem and the overall buffering problem of oil well facilities, troubling offshore wells are solved, and unexpected effects are achieved.
