Abstract

Conveyor belt is an important element of the conveyor. The strength of the steel cord conveyor belt largely determines the carrying capacity, and it also has a great impact on operational safety. In this paper, the effect of different factors on the strength of the steel cord conveyor belt splices was studied. The FEM was used for simulation analysis, and the corresponding tensile experiments were carried out to verify. Steel cords of different lengths were simulated, and the simulation results agree well with the experimental results. On this basis, the steel cord length, steel cord diameter, rubber thickness, and different number of steel cords were investigated to study the effect on the pullout force of the steel cord conveyor belt splice. The numerical simulation results show that different steel cord diameters have more significant effect on the strength of the conveyor belt splice compared to rubber. The steel cord length and steel cord diameter impact on the steel cord conveyor belt is approximately linear. For the different number of the steel cords, the increase in the number of steel cords does not mean that the tension will increase by the same multiple, and the increase in pullout force is less than the increase in the number of steel cords. It provides guidance for the production of steel cord conveyor belts.

Summary

Introduction

As a continuously moving transport facility, the conveyor has been widely used in fields such as mining, coal, port, electric power, chemical industry, metallurgy, architecture, and food [1, 2]. In previous studies and publications, researchers were more focused on the conveyor construction and conveyor belt splice strength detection. For the strength factors of the steel cord conveyor belt splice, they paid insufficient attention, the strength significantly affects the whole transport facility and even the whole system on the durability and reliability [4]. In 1979, Harrison first proposed a nondestructive testing method for a steel rope of a conveyor belt based on the principle of electromagnetic induction and developed a CBM steel core conveyor belt steel rope detection device [5]. Based on this principle, similar devices have been developed by German DMT Company and American Goodyear Company [6]. Four factors including the steel cord length, diameter, rubber thickness, and the number of steel cord will be mainly studied
