Abstract

The invention discloses a pneumatic control-based multi-filament spiral contact testing device inside a hoisting wire rope and a testing method thereof. Controlled wire rope internal multi-wire loading mechanism and drum loading mechanism. The multi-wire spiral contact test device inside the hoisting steel wire rope based on pneumatic control in the present invention can realize the working condition of the multi-wire spiral contact inside the steel wire rope strand on one experimental device, and truly simulate the friction and wear between the steel wires inside the steel wire rope strand and the steel layer There are two kinds of motion behaviors of friction and wear between the steel layer. The experimental device adopts pneumatic control to realize the adjustable and controllable loading force of each part, which makes the control process easier and the experimental data more accurate.

Description

technical field [0001] The invention relates to a device and a method for testing the internal multi-filament spiral contact of a hoisting wire rope based on pneumatic control. Background technique [0002] The steel wire rope is a flexible lifting structure with a three-dimensional spiral space structure, which is twisted into strands at a certain lay angle, and then twisted into a rope. Noise can withstand large axial loads, and has the advantages of small 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, which reduces the service life of the steel wire rope, or causes the broken wire inside the steel wire rope, which threatens the safety of lifting and transportation. Therefore, it is of great significance to master the multi-filament spiral contact conditions inside the wire rope and its...
