Copper alloy offshore oil well power-assisted device achieving threaded piston shock absorption
The invention relates to an offshore oil well assisting device, in particular to a copper alloy offshore oil well power-assisted device achieving threaded piston shock absorption. Platform hinges are arranged at the four corners of an operating platform to be connected with the upper hole ends of threaded piston shock absorbers, and the lower hole ends of the threaded piston shock absorbers are connected with fixed supporting legs. An oscillating bar pin shaft on an oscillating bar base is fixedly connected with a well drilling oscillating bar in a rotating mode, one side end of the well drilling oscillating bar is fixedly connected with a big well drilling rope, and the big well drilling rope penetrates through a platform drilling hole in the operating platform and then goes deep into a seafloor oil well bed. A transmission chain is arranged between an output chain wheel on a disc type water-cooling chain wheel motor and a chain wheel rotating table. The threaded piston shock absorbers and the plane of the operating platform are arranged at the included angle of 45 degrees, and it is guaranteed that the operating platform is stably fixed; the threaded piston shock absorbers achieve two-way shock absorption through the combination of threaded connecting and double-piston sealing, the disc type water-cooling chain wheel motor and the welding piston two-way shock absorbers are combined together through the operating platform, and the two problems troubling offshore oil wells all the time are solved at the same time.
