Abstract

The invention discloses a pneumatic control-based lifting steel wire rope internal multi-wire spiral contact testing device and a testing method thereof. The device comprises a workbench, a steel wirerope strand internal multi-wire spiral contact mechanism based on pneumatic control, a steel wire rope strand internal multi-wire loading mechanism based on pneumatic control and a roller loading mechanism. According to the pneumatic control-based lifting steel wire rope internal multi-wire spiral contact testing device, the working condition of multi-wire spiral contact in the steel wire rope strand can be realized on one experimental device, and two motion behaviors of frictional wear between steel wires in the steel wire rope strand and frictional wear between steel layers can be truly simulated. The experiment device is pneumatically controlled, so that the loading force of each part is adjustable and controllable, the control process is simpler and more convenient, and the experimentdata is more accurate.

Description

technical field [0001] The invention relates to a multi-filament spiral contact testing device and method based on pneumatic control 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. 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 wire rope, or causing broken wires inside the steel wire rope, threatening the safety of lifting and transportation. Therefore, it is of great si...
