The invention discloses a hydraulic balance lifting appliance which comprises a main cross beam and two auxiliary cross beams. The middle of the main cross beam is provided with a rotary connection base, and two main hanging brackets are symmetrically installed in the middle of the main cross beam through main hanging bracket guide rails. Each main hanging bracket is specifically provided with a main hanging bracket adjusting oil cylinder used for adjusting the position of the main hanging bracket. The lower portion of each main hanging bracket is connected with the middle of the corresponding auxiliary cross beam through a rotating connection base. Each auxiliary cross beam is provided with at least one pair of auxiliary hanging brackets symmetrically through auxiliary hanging bracket guide rails arranged at the top in the longitudinal direction. Each auxiliary hanging bracket is specifically provided with an auxiliary hanging bracket adjusting oil cylinder used for adjusting the position of the auxiliary hanging bracket. Two hydraulic block balance oil cylinders are arranged between the top of each auxiliary hanging bracket and the top of the corresponding auxiliary cross beam in the transverse direction of the auxiliary cross beam. The hydraulic block balance oil cylinders on the auxiliary cross beams communicate through oil pipes. The lower portion of each auxiliary hanging bracket is provided with a hanging belt. The hydraulic balance lifting appliance maintains uniform distribution of loads automatically in the hanging process of nuclear island installation structure modules, the risk of overturning caused by lateral loads is effectively avoided, and safety and reliability are achieved.
Description
technical field [0001] The invention relates to a hydraulic balance sling, which is used for the overall hoisting operation of structural modules in the nuclear island installation project of nuclear power plant construction, and belongs to the field of nuclear technology application. Background technique [0002] The Chinese government has decided to build new nuclear power plants at a rate of 6 to 8 per year in the 13th Five-Year Plan starting in 2016. In order to introduce self-developed new nuclear power plants, a total of 500 billion yuan will be invested, and strive to surpass Japan and the United States in terms of power generation capacity and operating quantity before 2030, and become the world's largest "nuclear energy power." [0003] In the construction of nuclear power plants, the nuclear island installation structure modules have the following characteristics: [0004] 1. The lifting weight is large. The largest structural module weighs more than 1,100 tons. ...
