The invention relates to an auxiliary offshore oil well device, in particular to an auxiliary zinc alloy welding piston buffer offshore oil well machinery. A synchronous driving belt is arranged between an output synchronous belt wheel and a belt wheel turn plate of a squirrel cage type flame-proof synchronous belt wheel motor, each welding piston buffer uses double-piston seal bidirectional buffer connected and combined in a welding mode, each welding piston buffer can simultaneously bear pull or pressure, and a work platform can resist the sea wave impact from any direction; a sealing ring is arranged on the threaded bottom plane in a cable box end cover to secondarily isolate electric spark to further avoid the electric spark leakage, the flame-proof effect is good, and the safety performance is high. Through combining the squirrel cage type flame-proof synchronous belt wheel motor with the welding piston buffers for the work platform, the problem of easiness in damage of a power source motor and the whole buffer problem of oil well facilities which always perplex the offshore oil well are solved, and the effect is unexpected.
