BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for upgrading a transmission tower. More particularly, the present invention relates to an apparatus and a method for upgrading a transmission tower.

As the industry develops, the demand for electric power is increasing, the number of facilities for transmitting power is increasing, and the facilities are becoming larger and larger due to urbanization.

Due to the enlargement of such facilities, the safety distance between the facility and the transmission line can not be secured, and the risk of contact is increasing. As the safety distance is not secured, good quality of power supply and malfunction are also increasing.

Therefore, it is necessary to raise the transmission tower to ensure the safe separation distance between the transmission line and the facility.

However, in order to raise the transmission tower, it is troublesome to construct a separate temporary transmission tower or a new transmission tower.

For the installation of such temporary transmission towers or new transmission towers, transmission towers were developed for the purpose of raising transmission towers due to difficulties in securing paper, safety accidents due to insufficient safety distance, concern about facility breakdown, and high costs .

As shown in FIG. 1, the construction of a steel tower using the transmission towers of the present invention is carried out by installing a steel tower elevator (Helper-Tower) on the existing tower (a) (C) raise the top of the existing steel tower, and (d) raise the height of the steel tower and remove the steel tower elevator (Helper-Tower) (e).

However, the conventional upward method requires a minimum of 20 to 30 days in order to construct the temporary transmission line, the work process is complicated, and there is a problem that the construction cost is increased due to the installation of the main rail for the provision of the temporary transmission line

Also, there is a problem that the method can not be applied when the foundation of the pylon is above the standard of pylon control, and the beauty of the pylon is obstructed after the completion of the pylon.
