Device and method for testing bearing property of mining annular steel wire rope

摘要

A device for testing the bearing property of a mining annular steel wire rope (5), comprising a steel wire rope loading device (1), a motor drive device (2), a detouring wheel positioning device (3), a positioning platform (4), and a drive wheel positioning device (6). The steel wire rope loading device (1) is arranged in the middle of a circular arc-shaped section on the left of the positioning platform (4) in the horizontal direction. The motor drive device (2) and the detouring wheel positioning device (3) are arranged at a circular arc-shaped section on the left of the positioning platform (4) in the radial direction, and are symmetrically arranged at both sides of the steel wire rope loading device (1). The drive wheel positioning device (6) is uniformly arranged at the circular arc-shaped section on the right of the positioning platform (4) in the radial direction. The drive wheel winding process and the detouring wheel rope returning process of the annular steel wire rope (5) in an endless rope transportation process are simulated on the basis that a hydraulic cylinder loads, a double-way hydraulic motor drives the annular steel wire rope (5), and a double-way hydraulic pump provides the load damping, and the tensile property and the fatigue life of the annular steel wire rope (5) are tested so as to accurately estimate the loading property thereof. The reliability is high, the university is high, and important significance in guaranteeing the safety of the annular steel wire rope (5) in the endless rope transportation system is achieved.
