Abstract

The invention provides a power transmission tower angle steel mechanical property testing device and method, and the device comprises a pedestal and a to-be-tested piece connected with the pedestal; one end of the to-be-tested piece is connected with the pedestal, and two end faces of the other end of the to-be-tested piece are fixedly connected with a first lifting lug and a second lifting lug respectively; the first lifting lug is connected with one end of a load tester, and the other end of the load tester is connected with the loading mechanism, and the second lifting lug is connected witha deflection tester; the middle section of the to-be-tested piece is connected with the static strain tester through a plurality of data lines; and mechanical testing can be carried out on the reinforced and repaired angle steel, the newly developed reinforcing and repairing technology can meet the requirement that related mechanical property tests need to be carried out in the research and development stage, and it can be guaranteed that the reinforcing effect of the angle steel meets the requirement for safe and stable operation of an angle steel tower.

Description

technical field [0001] The invention relates to a device and a method for testing the mechanical properties of an angle steel reinforcement of a power transmission tower. Background technique [0002] The transmission angle steel tower is an important supporting equipment for the transmission line, and its safety and reliability is an important guarantee for the safe operation of the power grid. Some in-service transmission angle steel towers have potential safety hazards due to insufficient design strength, improper material selection, changes in geographical environment, corrosion, icing, and external force damage, which seriously threaten the safety of the power grid. Transmission pole repair and reinforcement technology is a new technology developed in recent years. This technology can effectively eliminate the strength of transmission tower through reasonable design of transmission tower angle steel reinforcement and reinforcement structure, and the use of fusion weldin...
