When the piston rod of the first hydraulic cylinder 1 extends out, the moving stroke of the power head 8 can be larger than that of the piston rod of the first hydraulic cylinder 1.
According to the pressurizing device provided by the embodiment of the invention, the first hydraulic cylinder 1, the pressurizing rope 2 and the pulley block are combined to provide pressure for the power head 8, compared with the hoisting pressurizing in the prior art, the pressurizing device has the advantages of low cost and convenience in installation, and the defect that the stroke is influenced by the length and the installation position of the oil cylinder when the oil cylinder is used for pressurizing in the prior art is overcome.
