Abstract

Currently, the widespread use of tubular belt conveyors is constrained by insufficient justification of the conveyor parameters. In the work, on the basis of the theory of the limiting equilibrium state of bulk load, equations of equilibrium of load on the belt of an inclined tubular conveyor are obtained. It is assumed that the belt was a rigid cylinder filled with bulk material in extreme equilibrium. Based on the obtained equilibrium equation, the analytical dependences of the limiting angle of inclination of the belt conveyor with a tubular belt on the degree of unfilling with the bulk load of the belt and the properties of the bulk load are found. From the analysis of these dependencies it follows that the limiting angle of inclination of the tubular belt conveyor depends on the angle of internal friction of the transported load, the angle of friction of the load on the conveyor belt, the angle of unfilling of the belt with load and does not depend on the radius of the conveyor belt.

Highlights

At present, belt conveyors with tubular belt are widely used
Perten Yu.A., Chernenko V.D., Galkin V.I., Dmitriev V.G. are engaged in questions of stability and the maximum angle of inclination of the tubular belt conveyor
In [1], the problem of stability of bulk load of an inclined tubular conveyor is solved, while the load when moving along the tubular conveyor belt is affected by the friction forces of the load on the belt, directed along the belt, components of the load’s gravity directed against the movement belts, and the bulk load back up force, directed in the same way as the friction force, along the movement of the belt

Summary

Introduction

Belt conveyors with tubular belt are widely used. The main advantage of the tubular belt conveyor is the lack of contact of the load with the environment, as well as the ability to transport load along curved routes without reloading nodes.In addition, unlike a conveyor belt with a deep grooved belt, the transported load on the conveyor belt is more stable due to the limited space.Perten Yu.A., Chernenko V.D., Galkin V.I., Dmitriev V.G. are engaged in questions of stability and the maximum angle of inclination of the tubular belt conveyor.In [1], the problem of stability of bulk load of an inclined tubular conveyor is solved, while the load when moving along the tubular conveyor belt is affected by the friction forces of the load on the belt, directed along the belt, components of the load’s gravity directed against the movement belts, and the bulk load back up force, directed in the same way as the friction force, along the movement of the belt.such a mode of equilibrium of bulk load in a tubular conveyor is possible with conveyor tilt angles much higher than permissible.
