Description

A support frame for fixing a pole

technical field

The invention relates to power transmission equipment, in particular to a support frame for fixing a pole.

Background technique

With the development of transmission lines, various regions have begun to erect high-voltage direct and alternating current transmission towers, and these towers need to be erected with pole-holding support frames. The pole support frame not only needs to carry strong vertical and horizontal forces, but also needs to be suitable for environments with harsh ground conditions.

Most of the existing pole support frames use concrete cast-in-place foundations. This structure is not only expensive to manufacture, but also takes a long construction period and takes up a lot of land, and it cannot be reused. The prefabricated foundation can be reused and is easy to install, but it has higher requirements for the endurance of the ground base, and the location of the tower legs is higher for laying the stay wires. When the tower feet are not at the same level, it is more difficult to install the stay wires. have a certain impact on construction.

Therefore, it is necessary to provide a support frame for fixing the pole, which not only has strong vertical and horizontal bearing capacity, but also has the advantages of small size, light weight, and easy installation and transportation.
