Abstract
The invention discloses a modularized combined-type lifting device for a transformer bell cover. A left base module and a right base module are provided with a left double-shear-fork lifting module and a right double-shear-fork lifting module which are pushed and lifted by a left hydraulic cylinder and a right hydraulic cylinder respectively. A cross beam module is arranged on the top of the left double-shear-fork lifting module and the top of the right double-shear-fork lifting module. Lifting hooks used for lifting the bell cover of a transformer are arranged on the cross beam module. The cross beam module is provided with a displacement sensor used for detecting whether the lifting height of the left double-shear-fork lifting module is consistent with the lifting height of the right double-shear-fork lifting module or not. The displacement sensor is connected with a control system. The control system is connected with a synchronous control device which controls the synchronous movement of the left hydraulic cylinder and the right hydraulic cylinder. According to the lifting device for the transformer bell cover, the double-shear-fork-type gantry structure is adopted, the maximal lifting height can be up to 8 meters, and the maximal lifting weight can be up to 10 tons. Components which assemble the device are of modularized structures, assembling can be carried out according to actual needs, lifting of different heights and ranges can be achieved, and the task operation is convenient to carry out in an indoor space.
