Embodiment

[0028] Embodiments: The present invention includes a monitoring system and a monitoring method.

[0029] figure 1 It is a layout diagram of a wire rope drum monitoring system for a mine hoist according to the present invention. The monitoring system includes: an industrial camera 2 installed at the upper rear or lower front of the rope in the middle of the reel 1, a shaft encoder 3 installed at the shaft end of the reel 1 and connected to the shaft, and data that is sequentially connected to the shaft encoder 3 The acquisition card 4 and the industrial computer 5 ; the industrial camera 2 is connected to the industrial computer 5 through a cable 7 .

[0030] A method for judging the rope disorder of a mine hoist wire rope drum, specifically:

[0031] 1) The industrial computer 5 sets the judgment cycle T, the same sampling times n of the industrial camera 2 and the shaft encoder 3 within the judgment cycle T, that is, each sampling interval time Δt=T / n, and sets m·Δt as Sam...

Abstract

The invention relates to a disorder rope monitoring system for a winding reel of a mine hoist and a disorder rope judging method and belongs to disorder rope monitoring systems and methods for steel wire rope reels. Specifically, the disorder rope monitoring system comprises an industrial camera, a shaft encoder, a data acquisition card and an industrial control computer, wherein the industrial camera is arranged at the upper rear part or lower front part of a middle outlet rope of the reel, the shaft encoder is arranged at a shaft end of the reel and is connected with a shaft, and the data acquisition card and the industrial control computer are sequentially connected with the shaft encoder; the industrial camera is connected with the industrial control computer through a communication cable. The disorder rope judging method comprises the steps of measuring the rotation angle of the reel through the shaft encoder, measuring the rope outlet position of a steel wire rope through the industrial camera, and judging whether the rope is in disorder or not through analyzing the change characteristics of angles and rope outlet positions in a certain period. The monitoring system is convenient in mounting and has no need of modifying the reel, and meanwhile, the safety of operation of a mine hoist system is improved.

Description

technical field [0001] The present invention relates to a system and method for detecting disordered ropes of steel wire rope drums, in particular to a monitoring system and method for detecting disordered ropes of winding drums of mine hoists, suitable for single-rope or multi-rope winding drums, especially for construction shafts Or the use of winding drums for mine hoists that have been built. Background technique [0002] The lifting system is an important part of the transportation system, and the wire rope plays an important role in the lifting system. For single-rope or multi-rope winding drums, the lifted object is moved up and down by winding the wire rope on the drum. Due to various reasons, the steel wire rope may not be arranged according to the existing trajectory during the winding process on the drum, that is, the phenomenon of rope disorder occurs. Rope disorder is extremely harmful to the steel wire rope. It will speed up the wear of the steel wire rope, a...
