A power transmission emergency repair tower

Abstract

The invention discloses a power transmission repair tower. The power transmission repair tower comprises a main tower body, a tower head connecting device and a tower head. The main tower body comprises N first tower body segments and M second tower body segments. The first tower body segments and the second tower body segments are all of straight polygon prism structures. The N first tower body segments and the M second tower body segments are orderly distributed at intervals. The bottom of one first tower body segment is connected to the top of an adjacent second tower body segment in a sleeved manner. The top of the first tower body segment is connected to the bottom of another adjacent second tower body segment in a sleeved manner. The bottom of the tower head connecting device is equipped with a first connecting mechanism used for connecting with the top of the main tower body. The top of the tower head connecting device is equipped with a second connecting mechanism used for connecting with the tower head. Through an assembly mode, the power transmission repair tower is formed. Transport of the overall power transmission tower is avoided. The limit of the transport process isremoved in order to ensure that first-aid repair work can be timely conducted.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a power transmission emergency repair tower. Background technique [0002] Transmission lines are important lifeline projects, and their safety is directly related to national economic construction and people's lives. It is very important to ensure the normal and reliable operation of power grid transmission lines. The transmission line tower line system has the characteristics of high tower, large span, and strong flexibility. The geometric nonlinearity of the ground wire and the insulator string and the coupling between the tower lines make the effect of the transmission line tower line system on the excitation of typhoon and other environments Very sensitive and prone to damage phenomena such as mechanical vibration, fatigue damage and dynamic collapse. [0003] The southeast coast of my country is not hit by typhoons every year. When a large typhoon lands, it ofte...

Problems solved by technology

When building an emergency repair tower, it is necessary to use the main pole with the same height as the original transmission tower. However, it is very difficult to transport the main pole with a height of tens of meters or even a hundred meters. It is necessary to transport such a main pole within a specific period of time. Carry out transportation, such as in the early morning, to avoid the impact of the transportation main pole on local traffic, thus limiting the construction time of the emergency repair tower
