Description

Technical Field

[0001] The present application relates to the technical field of power transmission and transformation installation, and more specifically, to a power transmission and transformation line installation and maintenance device. Background Art

[0002] Transformer installation is particularly important in the installation and maintenance of power transmission and transformation lines. Because the transformer itself is heavy, it is usually necessary to use a crane to carry out lifting installation. However, due to the limited location of some transformer installation sites, it is difficult for cranes to enter the installation site, so manual and other methods are required to carry out lifting and installation, which increases the difficulty of installation and maintenance work. The existing public technology number CN219507609U proposes a power transmission and transformation line installation and maintenance device. The device is not only easy to move, but also has high stability during use, is safer, simple to use, and easy to operate. Regarding the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: although the installation and maintenance device in the comparative literature can realize the lifting and transportation of line installation equipment such as transformers, when the transformer is lifted to a certain installation height, manual transportation is still required for auxiliary installation or disassembly, and the construction difficulty is still large, and the practicality is reduced. In view of this, we propose a power transmission and transformation line installation and maintenance device. Utility Model Content
