Abstract

The invention discloses an angle iron cross diagonal member stable bearing capacity test device and relates to the field of power supply test devices. The test device comprises two fixed structures, afirst supporting main material, a second supporting main material, a tension and pressure measurement assembly, a horizontal hydraulic jack and an electronic displacement meter, wherein the two fixedstructures are separately arranged, the first supporting main material and the second supporting main material are respectively hinged to one fixed structure, the tension and pressure measurement assembly comprises a height-adjustable pressure sensor which is fixedly arranged and used for measuring pressure or tension of the hydraulic jack, the horizontal hydraulic jack is fixedly arranged, and the electronic displacement meter is used for measuring displacement of the ends, far from the fixed structure of the first supporting main material and the second supporting main material. The angle iron cross diagonal member stable bearing test device disclosed by the invention takes restraining action of torsion rigidity of the other rod to a target press rod into consideration; compared with anexisting test device, a device platform which can detect flexural-torsional instability load data of angle iron members more reasonably and can obtain more accurate stable bearing capacity calculation values is provided.

Description

technical field [0001] The invention relates to the field of power supply test devices, in particular to a test device and method for the stable bearing capacity of angle steel crossed oblique members. Background technique [0002] Goaf subsidence has always been a major hidden danger affecting the safe operation of power lines. Geological disasters in goafs have caused transmission line towers to tilt, foundations to sink, and incidents of forced outages and line changes have occurred from time to time. The wind deflection of the ground wire failed, and some lines were even forced to cut off power, move towers, and reroute. The scientific calculation of the stable bearing capacity of angle steel cross-slope members is an important content in the structural design of transmission towers, and it is also a prerequisite for the research on the failure mechanism and deformation control technology of transmission towers in mining areas. [0003] At present, some studies have bee...
