“…e excessive transverse vibration displacement of the wire rope will cause rope jumping fault and then will lead to the tension change of the ropes. us, the excessive transverse vibration of the rope affects the enwinding process of the mine hoist [2]. erefore, the transverse vibration of the catenary of the winding mine hoisting systems is taken as the main evaluation index for the orderly arrangement and the engineering safety of the multilayer winding wire rope.…”

The characteristics of rope vibration of the winding mine hoist are one of the main evaluation indices for evaluating the characteristics of the engineering mechanics and the safety coefficient of the hoist system. For this purpose, research was conducted on the vision-based measurement method for catenary transverse vibration. Firstly, a high-speed camera was utilized to capture grayscale images of the catenary transverse vibration. Secondly, the region of interest (ROI) was selected, and the ROI was binarized based on the wavelet edge extraction algorithm. Thirdly, in the ROI, the centroid position of the rope was obtained by calculating the matrix, which was described by the binary, and later, the transverse vibration signal of the catenary was obtained. Finally, the empirical mode decomposition (EMD) method was used to remove the periodic excitation caused by the displacement of the catenary winding. The experimental results show that the proposed method quickly and accurately comprehends the noncontact measurement of the catenary transverse vibration, and this method could also provide the technical support necessary for the measurement and evaluation of the safety parameters of the hoisting system.

“…In particular, the author defines braking parameters that will not lead to critical consequences. The work [18] is devoted to the study of the relationship between the slipping of the hoisting rope during the operation of the hoisting machine and the tension force of the rope. In the article [19], a mathematical model of the skip motion is developed and the analysis of accounting for various parameters on the nature of the oscillations of the studied system is conducted.…”

An analytical solution is presented to the problem of determining the force effect of lifting vessel (skip) on guides during its movement in the mine shaft. Forces values are obtained using acceleration data from sensors of motion smoothness through monitoring system. The technique developed allows to determine skip force effect on guides along all axes of horizontal coordinate system. A transition from a force to impulse action is provided. The interrelation of force action surges with guides profile deviations is analyzed. The results of this study can be widely used to identify the areas in the mine shaft where emergency could potentially occur.
