The invention discloses a four-point lifting device for a large offshore booster station. The four-point lifting device comprises a lifting frame, four upper lifting belts and four lower lifting belts. The plane of the hoisting frame is rectangular, and the hoisting frame comprises two cross beams, two longitudinal beams and four middle connecting assemblies which are connected between the two ends of the two cross beams and the two ends of the two longitudinal beams in a one-to-one correspondence manner; each cross beam and each longitudinal beam comprise two end sections and a middle beam section connected between the two end sections; the middle beam section is formed by splicing a plurality of middle pipe sections through flange plates; each middle connecting assembly comprises a middle connecting piece, an upper pin shaft sleeve piece, a lower pin shaft sleeve piece, an upper rope groove wheel and a lower rope groove wheel. The four upper lifting belts are connected between the upper rope grooved pulleys of the four middle connecting assemblies and a main lifting hook of the crane in a one-to-one correspondence manner; the four lower lifting belts are connected between the lower rope grooved wheels of the four middle connecting assemblies and the four lifting lugs of the booster station in a one-to-one correspondence mode. According to the lifting device, four lifting lugs on the booster station can be vertically lifted, and the lifting device has the advantages of being good in balance, safe and reliable.
