Abstract

The invention discloses a device for testing the mechanical property of a power transmission tower angle steel reinforcing piece. The device comprises a deflection measuring instrument, a micro-straintester, a load measuring instrument, a displacement tension structure, a bracket I, a bracket II and a base. The micro-strain tester is installed on the bracket I. A strain gauge is attached to the angle steel reinforcing piece; the strain gauge is connected with the micro-strain tester through a data line. A fixed plate is arranged on the bracket II; the deflection measuring instrument is connected to the bracket II through the fixed plate. A steel plate mounting block is arranged on the base, one end of the angle steel reinforcing piece is connected with the steel plate mounting block, theother end of the angle steel reinforcing piece is connected with the deflection measuring instrument through a first connecting rod, the other end of the angle steel reinforcing piece is connected with the displacement tension structure, and the load measuring instrument is connected with the displacement tension structure. According to the invention, the detection of mechanical properties such asmicro-strain, load and deflection of the angle steel reinforcing piece can be completed at the same time, and the reinforcing effect of the reinforcing part can be reliably and accurately represented.

Description

technical field [0001] The invention relates to the technical field of reinforcement and reinforcement of transmission towers, in particular to a device for testing the mechanical properties of angle steel reinforcements of transmission towers. 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 tower 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 st...
