Description

Transformer disassembly device

technical field

The utility model relates to a dismounting device for a transformer.

Background technique

At present, there are two methods commonly used by power bureaus to install and replace transformers: the first is to use large hoisting machinery such as cranes, and the second is to use an inclined platform for manual lifting. Due to the large size of the crane, the installation and replacement process occupies a large area, which seriously hinders traffic in the case of narrow streets and roads, causing great inconvenience to vehicles. In addition, in areas with poor road conditions such as mountainous areas, due to the limitations of the installation environment and other restrictions, the method of manpower lifting and landing can only be used when large lifting machinery cannot enter. This method is likely to cause accidents, cause personal injury and property loss, and uncertain factors larger.

The patent with the publication number CN 102951560 discloses a hoisting crane in the power system, but it also has many shortcomings, for example: the pole is not stable enough during the hoisting process, which may easily cause potential safety hazards. Other structures are adjusted at any time, and the installation process is cumbersome.
