Abstract

The invention discloses a power equipment hoisting device for narrow space. A left double-scissor-fork lifting device and a right double-scissor-fork lifting device pushed by a left hydraulic cylinder and a right hydraulic cylinder to ascend and descend are mounted on a left base and a right base respectively, a cross beam is mounted at the tops of the left and right double-scissor-fork lifting devices, a hanging hook for lifting a transformer hanging bell cover is mounted on the cross beam, a displacement sensor for detecting whether lifting height of the left and right double-scissor-fork lifting devices is uniform or not is mounted on the cross beam and connected with a control system, the cross beam comprises a left longitudinal rod set, a right longitudinal rod set, a front cross rod and a rear cross rod, each of the left longitudinal rod set and the right longitudinal rod set is composed of two longitudinal rods, each longitudinal rod is fixedly connected with the top of a scissor-fork lifting member of the corresponding double-scissor-fork lifting device, and four cross rods which are parallel to each other are fixedly connected with the left longitudinal set and the right longitudinal set. The transformer hoisting device is of a double-scissor-fork gantry structure, maximum lifting height can reach 8m, and maximum lifting weight can reach 10t.

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 hoisting device for electrical equipment in a narrow space with reasonable structure and good working performance. [0004] Technical solution of the present invention is: [0005] A hoisting device for power equipment in a narrow space, 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 lifted and lowered by left and right hydraulic...
