Construction method of high-low voltage power transmission line metal tower

YANG XING / RONG ZHIQIANG

The invention relates to a construction method of a high-low voltage power transmission line metal tower. A construction device of the high-low voltage power transmission line metal tower is used andcomprises a frame fixing mechanism and a traction group, wherein the frame fixing mechanism is connected with the existing working ground in a sliding fit mode, the traction group is arranged on the front side of the frame fixing mechanism, and the lower end of the traction group is connected with the existing working ground in a sliding fit mode. The design concept of a multi-stable structure isadopted for the construction of the high-low voltage power transmission line metal tower, and then the overall stability of electric pole hoisting and a foundation supporting structure is improved; and besides, an elastic tightening and clamping mode is adopted for an electric pole so as to cooperate with a hoisting operation of the electric pole, and the application range of clamping and fixing the electric poles of different sizes and types within a certain range can be widened.

本发明涉及一种高低压输电线路金属杆塔施工方法，其使用了一种高低压输电线路金属杆塔施工装置，该高低压输电线路金属杆塔施工装置包括固架机构和牵引组，所述的固架机构通过滑动配合方式与已有工作地面相连，固架机构的前侧设置有牵引组，牵引组的下端通过滑动配合方式与已有工作地面相连，本发明采用多重稳固结构的设计理念进行高低压输电线路金属杆塔施工，进而提高电杆吊装以及基础支撑结构的整体稳定性，同时对电杆采用的弹性绷紧夹固方式以便于配合电杆的吊装操作，且又可提高对一定范围不同尺寸类型电杆夹固的适用范围。
