Abstract

The aim of the thesis is developing wind power installing equipment with self-determination product, that is two-sides lifting tool of steel tube stake. At first, the mechanism of it was designed and its principle was also expounded. Next, the gripping mechanism composed of hydraulic cylinder and inclined gripping blocks was designed and its force relation was analyzed, so the positive pressure of gripping blocks and friction coefficients were calculated. Then, using the method of the finite elements to analyze and check the strength of the small lifting arm. In the end, its model machine was made and the experiment of suspending steel tube was done, and verified its rationality and reliability on the scheme, which founded the base of theory and practice for the engineering machine.
