Abstract

The invention relates to a folding type suspension arm device supported by an electric pole. The folding type suspension arm device comprises a telescopic supporting rod body connected with the electric pole through a fixing seat, a horizontal suspension arm hinged to the upper end of the supporting rod body, an inclined supporting rod connecting the supporting rod body and the horizontal suspension arm and a driving mechanism arranged on the lower portion of the supporting rod body. A first traction rope set of the driving mechanism winds across a pulley at the upper end of the supporting rod body and a pulley at the moving end of the horizontal suspension arm and then is connected with a hoisting hook. The folding type suspension arm device supported by the electric pole has the characteristics of being safe and stable in structure, simple in erection process and the like; the existing electric pole is used for supporting the device, the device structure is thus simplified, and safety of the construction process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a folding boom device supported by electric poles. Background technique [0002] Transformers are widely used in our lives. Power transformers are one of the core equipment of the power grid, so their stable and reliable operation will play a very important role in the safety of the power system. The installation methods of transformers can be divided into the following types: 1) installation of single-rod transformer; 2) installation of double-pole transformer; 3) masonry of floor transformer; 4) masonry of floor transformer . [0003] For the single-pole transformer, it is suitable for installing a 10~30kv*A transformer. The single-pole transformer is to fix the transformer, drop-out fuse and lightning arrester on one pole, and the distance between the transformer stand and the ground is generally not less than 2.8m. For the double-pole transformer, it is...
