Abstract

The invention discloses a hoisting apparatus for indoor transformer gas-insulated switchgears with various grades. A left double-fork lifting device lifted by the pushing of a left hydraulic cylinder is installed on a left pedestal. A right double-fork lifting device lifted by the pushing of a right hydraulic cylinder is installed on a right pedestal. A crossbeam is installed on the tops of the left double-fork lifting device and the right double-fork lifting device and is provided with a hook for lifting a transformer belljar. A displacement sensor is installed on the crossbeam, is used for detecting whether the lifted height of the left double-fork lifting device is consistent with that of the right double-fork lifting device, and is connected with a control system. The crossbeam comprises a left group of longitudinal rods, a right group of longitudinal rods, a front cross bar, and a rear cross bar. Each of the left group of longitudinal rods and the right group of longitudinal rods is composed of two longitudinal rods. Each longitudinal rod is fixedly connected with the top of the corresponding fork lifting member of the double-fork lifting devices. The four parallel cross bars are fixedly connected with the left group of longitudinal rods and the right group of longitudinal rods. The hoisting apparatus utilize the double-fork gantry structure and achieves a maximum lifting height of 8 meters and maximum lifting weight of 10 tons.

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 lifting device for indoor various transformer grade gas insulated switchgears with reasonable structure and good working performance. [0004] Technical solution of the present invention is: [0005] A lifting device for indoor gas insulated switchgear of various transformer grades, characterized in that it includes left and right bases, and left and right double scissor lifting devices are respectively installed on the left and right bases to be ...
