A detection device for the vibration amplitude of a steel wire rope

Abstract

The invention relates to a detection device for the dither amplitude of a steel wire rope. The detection device comprises a detection head (A), an inclined angle adjuster (3), an elevation adjuster (5), a support (6), a supporting foot (7) and a data acquisition unit (8). The detection head (A) is mounted on the inclined angle adjuster (3), and the inclined angle adjuster (3) is connected with the elevation adjuster (5); the elevation adjuster (5) is mounted at the middle part of a shaft on the top of the support (6), and the supporting foot (7) is connected to the bottom of the support (6) through a hinge; the data acquisition unit (8) is connected with the detection head (A) through a data line; the detection head (A) comprises an emitter (1), a receiver (2) and a supporting arm (4); and the emitter (1) and the receiver (2) are erected on the two opposite sides of the supporting arm (4). According to the technical scheme, dither of the steel wire rope can be effectively and intuitively detected and recorded, the practical information can be provided for fault diagnosis of a lifter, and happening of accidents of the lifter can be effectively prevented.

Description

technical field [0001] The invention relates to a new device capable of visually and effectively testing the swing range of a hoisting wire rope, which can be applied to a mine hoist to provide practical information for state analysis and fault diagnosis of the mine hoist, and can effectively eliminate hidden dangers of accidents. Background technique [0002] Mine hoisting wire rope has a heavy load during operation and is excited by various vibration sources, so various vibrations will inevitably occur. Especially in the start-up acceleration stage or deceleration stop stage of the hoist, the jitter is particularly prominent. The unbalanced tension of the first rope, the deformation of the tank, the failure of the braking system, the insufficient roundness of the drum or the radial runout of the main shaft and other factors will cause the vibration of the wire rope, and the vibration amplitude can reach up to about 40cm. Although the vibration problem does not directly af...
