Abstract

The invention discloses tension test equipment and a steel wire rope tension test method thereof. A tension bar is arranged, a clamping block is arranged at one end of the tension bar, and the clamping block and a clamping sleeve are clamped and fixed through a clamping groove; when a tension test is carried out, a transition block applies acting force to the clamping sleeve through a fixing shaft, the clamping sleeve applies acting force to the connecting rod through the connecting block, the acting force is transmitted to a first bracket through the connecting rod so as to provide drawing force for the steel wire rope; the clamping sleeve is clamped with the clamping block, the connection mode between the clamping sleeve and the clamping block is no longer hard contact, when the clampingsleeve transmits a tensile force, the steel wire rope is deformed under the action of tension, the instantaneous tensile force of the steel wire rope can be buffered in a clamping mode between the clamping sleeve and the clamping block, when the steel wire rope is stretched, the instantaneous acting force borne by the steel wire rope is not too large, and therefore damage to material performancecaused by the too large acting force at the moment of stress of the steel wire rope is avoided, and the tension test result of the steel wire rope is more accurate.

Description

technical field

[0001] The invention relates to the field of test equipment, in particular to a tension test equipment and a method for performing a steel wire rope tension test, belonging to the technical field of tension test equipment applications. Background technique

[0002] The tensile test of materials is mainly to determine the tensile properties of materials, and the quality of tensile properties can be detected by tensile tests. Tensile test (stress-strain test) generally clamps the two ends of the material sample on two fixtures at a certain distance, separates the two fixtures at a certain speed and stretches the sample, and measures the stress change on the sample. until the sample fails. Tensile test is one of the most widely used methods to study the mechanical strength of materials. When the existing steel wire rope tensile test equipment is used for tensile test, the steel wire rope is mainly clamped and fixed by the clamp of the tensile test, so that the ...
