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.

Description

technical field [0001] The invention relates to a lifting device for a transformer bell jar. Background technique [0002] In the prior art, the lifting of the indoor transformer bell jar generally adopts ordinary lifting facilities, and the building structure needs to be destroyed during the construction to operate, and the skills of the operators are greatly affected, and the working performance is not ideal, which needs further improvement. Contents of the invention [0003] The object of the present invention is to provide a modular combined transformer bell jar lifting device with reasonable structure and good working performance. [0004] Technical solution of the present invention is: [0005] A modularized combined transformer bell hoisting device, characterized in that it includes left and right base modules, on which are respectively installed left and right double-scissor lifting modules driven by left and right hydraulic cylinders, and left and right 1. A cro...
