Problems solved by technology

And this kind of broken line load has obvious dynamic impact characteristics, so it increases the damage to the structure. There is no device on the existing transmission tower to reduce the load after the fracture, and under the impact of high load, the connection of the transmission tower is easy to install. Denaturation and breakage, affecting the safety of use

Abstract

The invention discloses a main tower torsion preventing power transmission tower using lead core rubber, and belongs to the technical field of power transmission towers. The main tower torsion preventing power transmission tower using the lead core rubber comprises a main tower, the main tower is mounted on the ground, a main rotating shaft is arranged on the main tower, a low-hanging-point rotating arm is arranged on the outer side of the main rotating shaft, a low-hanging-point rotating arm sleeve is arranged on the low-hanging-point rotating arm, and the low-hanging-point rotating arm sleeve on the low-hanging-point rotating arm is movably connected with the main rotating shaft on the main tower through a friction piece. According to the main tower torsion preventing power transmissiontower using the lead core rubber, torsion and vibration borne by the main tower are effectively reduced, the main tower is well protected, and the lead core can dissipate kinetic energy and reduce vibration, therefore, beneficial effects of limiting excessive deformation and too fast deformation of the low-hanging-point rotating arm and reducing the vibration are achieved, rotating speed force isreduced, so that slow rotation is performed, and damage to the power transmission tower is reduced, and the influence of overall deformation on subsequent use is prevented, so that the power transmission tower can be maintained and mounted very conveniently.

Description

technical field [0001] The invention relates to the technical field of power transmission towers, in particular to a power transmission tower using lead rubber to prevent main tower torsion. Background technique [0002] The transmission tower is a common high-rise structure, which is usually subjected to gravity load, wind load, earthquake load, etc. At the same time, various loads on the transmission line on the transmission tower are finally transmitted to the transmission tower. Under normal circumstances, The force generated by the transmission line on the transmission tower on the transmission tower is close to balance, so the transmission tower is only affected by the vertical force and a small part of the unbalanced force. However, when the accident occurs, the transmission line on the transmission tower After an asymmetrical break, the transmission line will not only generate vertical loads but also horizontal loads on the transmission tower. And this kind of broke...
