Apparatus for measuring dynamic flexural property of wire rope core

Abstract

The invention discloses an apparatus for measuring dynamic flexural property of a wire rope core, comprising a frame, a guide wheel mounted at the top of the frame, a hydraulic cylinder vertically mounted on a pillar on one side of the frame, and a test wheel mounted below the hydraulic cylinder; the hydraulic cylinder is a constant-speed constant-stroke double-piston-rod hydraulic cylinder; one end of a core of a wire rope under test is connected with the lower end of the hydraulic cylinder, the other end of the core is passed through the test wheel mounted below the hydraulic cylinder and is connected with one end of a transmission wire rope, and the other end of the wire rope is passed through the guide wheel and is then fixedly connected to a weight; upper and lower limit switches are mounted on the pillar above the mounting position of the hydraulic cylinder, and a counter is mounted between the two limit switches. The apparatus can be used to accurately and rapidly measure the dynamic flexural property of a rope core in order to evaluate the quality of the core, basis is provided for the design, manufacture, usage and detection of the core, and accidents due to the breakage of the core during use of the wire rope are avoided.

Description

technical field [0001] The invention belongs to the technical field of detection equipment for steel wire rope cores, and mainly relates to a test device for measuring the anti-extrusion, anti-abrasion, anti-bending and anti-stretching performances of steel wire rope cores under dynamic deflection conditions and evaluating their quality. Background technique [0002] The steel wire rope is composed of steel wires, strands, and rope cores, arranged and combined according to design rules. Among them, the role of the rope core in the steel wire rope is mainly to support the pressure of the outer layer strands, to ensure that the steel wire rope can still maintain its original shape when it is subjected to bending and load extrusion during operation; secondly, the rope core can store grease. During the operation of the wire rope, it is used as the source of wire rope lubrication to make the wire lubricate well, improve the contact between the strands and wires of the wire rope, ...

AI Technical Summary

Problems solved by technology

However, there is still no suitable test device for the dynamic flexural performance of the rope core to carry out corresponding tests. Therefore, a test device for measuring the dynamic flexural performance of the rope core is designed and developed to detect and evaluate the quality of the rope core. It provides the design, manufacture, use and testing basis for the designer, manufacturer, user and testing organization of the rope core, and avoids safety accidents and quality accidents caused by the damage of the rope core during use, which has a creative role
