Abstract
The invention relates to offshore oil well auxiliary devices, in particularly to aluminium alloy steel flange piston damping offshore oil well power-assisted equipment. Flange hinges are arranged at the four corners of an operation platform to be connected with the upper hole ends of flange piston dampers. The lower hole ends of the flange piston dampers are connected with fixed supporting feet. A swing rod shaft pin on a swing rod base is rotatably and fixedly provided with a drilling swing rod. One side end of the drilling swing rod is fixedly connected with a big drilling rope, and the big drilling rope penetrates through a platform drill hole in an operation platform and then goes deep into a seabed oil well bed. A triangular driving belt is arranged between an output triangular belt wheel and a belt wheel turning table on a squirrel-cage water-cooling triangular belt-wheel motor.
