Abstract
The utility model relates to a hydraulic lifting device for machinery. A supporting barrel is arranged at the bottom of a to-be-supported article; a supporting block is arranged between the to-be-supported article and the supporting barrel; the supporting block is formed by integrally connecting an upper half cone with a lower half cone; the upper half cone is embedded into the bottom of the to-be-supported article; the lower half cone is inserted into the top end of the supporting barrel; the supporting barrel is divided into an upper half barrel and a lower half barrel; the inner diameter of the lower half barrel is less than the inner diameter of the upper half barrel; a sliding block column and an I-shaped adjusting block are respectively mounted in the upper half barrel and the lower half barrel in a sliding form; the top end of the I-shaped adjusting block is embedded into the bottom of the sliding block column; a sealing ring is arranged between the upper half barrel and the lower half barrel; the bottom end of the lower half barrel is communicated with a hydraulic oil injection system. The hydraulic lifting device for machinery has a simple structure; a split structure is adopted; the injection pressure of the hydraulic oil is utilized to indirectly jack the to-be-supported article; the adjusting process is stable and reliable; each structure point can bear larger load; the practical value is ultrahigh.
Description
Technical field
