Embodiment Construction

[0083] The present invention will be described in detail below in conjunction with specific embodiments.

[0084] Such as Figure 1-8 , lifting the internal multi-wire performance testing device of the steel wire rope, including a worktable, an internal multi-wire helical contact mechanism of the steel wire rope placed on the workbench, a multi-wire loading mechanism and a drum loading mechanism inside the steel wire rope;

[0085] The workbench includes four profile columns 47, two beams 46 welded between the profile columns, the workbench table top 1 supported by the four columns, the column 48 symmetrically welded on the workbench, and two beams welded on one side of the workbench. Rectangular holes for preventing interference on columns and workbenches.

[0086] In this embodiment, the central steel wire pulling and twisting mechanism is used to perform torsion and tension testing on the central steel wire in the steel wire strand. One end of the central steel wire is con...

Abstract

The invention discloses an improved testing device and method for an internal multi-wire performance of a steel wire rope. The device comprises a workbench, and a steel wire rope strand internal multi-wire spiral contact mechanism, a steel wire rope strand internal multi-wire loading mechanism and a roller loading mechanism all arranged on the workbench. According to the testing device, the multi-wire spiral contact condition in the steel wire rope strand can be realized, and frictional wear between wires in the strand as well as frictional wear between steel layers in the steel wire rope canbe simulated effectively.

Description

technical field [0001] The invention relates to a device and method for testing the performance of multiple wires inside a hoisting wire rope. Background technique [0002] The steel wire rope is a flexible hoisting structure with a three-dimensional helical space structure, which is twisted into strands at a certain twist angle, and then twisted into strands. Because it can transmit long-distance loads, it has a large bearing capacity, good flexibility, and smooth movement. Noise can withstand large axial loads, and has the advantages of low bending and torsional stiffness, so it is widely used in various practical engineering applications such as cranes, elevators, and mine hoists. However, due to its complex and changeable working conditions, including harsh working conditions such as high temperature, water (ice) and corrosive gas (liquid). As a result, the friction and wear of the steel wire inside the steel wire rope is serious, reducing the service life of the steel ...
