Research On Turning Mechanics Of Turning Belt Conveyor

The turning belt conveyor is so named because its body can be used for turning and conveying materials according to the small workmanship and flexibility of the conveying site. It has also become an indispensable turning conveying equipment in the production lines of major production enterprises. The turning mode of the turning belt conveyor has different tensions which have different effects on the materials it conveys. The turning radius of the high-incline belt conveyor is analyzed and judged, and the inclination angle to the side roller, the inclination angle of the roller group, the elastic modulus of the belt is bent to the space turning, and the static design theory of the large-incline belt conveyor is made. A more comprehensive discussion, especially in the study of plane turning, has carried out a force balance analysis from the overall consideration of the conveyor belt, coupled with the internal force factor, updated the theoretical formula, and made the design update of the large inclination belt conveyor closer In reality.

From the perspective of force balance, the influence of parameter changes on the turning radius of the natural turning large inclination belt conveyor is analyzed. Through the comparison of the calculated data list, it can be concluded that the tension change has the greatest impact on the turning radius. The changes in the groove angle and the elevation angle have the greatest effect. The influence of turning radius also has a big conclusion. Through the geometric analysis and force balance analysis of the conveyor belt at the convex and concave variable slopes, the mathematical model of the convex variable slope turning radius and the concave variable slope turning radius is obtained, and other constraints are used to determine the turning radius. Check to determine the appropriate turning radius. The horizontal turning of the T-shaped high-inclination belt conveyor is studied. Through the force analysis, the expression of the positive pressure on a single driving point and the horizontal turning radius is theoretically deduced, which verifies the T-shaped large-inclination belt conveyor Turns with a small radius of curvature can be achieved. The force model of the turning section is analyzed from a three-dimensional perspective, and the normal and tangential balance equations of the turning section are established under the condition of force balance.

Several methods of large-angle horizontal turning are compared, and how to use linear friction drive to achieve large-angle horizontal natural turning is emphasized. It is pointed out that using linear friction drive can greatly reduce the tension at the starting point of the curve section, thereby effectively reducing the turning radius. The detailed calculation method and the problems that should be paid attention to in the specific design are put forward. The dynamic analysis of the flat turning belt conveyor with large inclination is studied, and the unconditionally stable Wilson-θ method is used to solve the dynamic problem of the large inclination belt conveyor based on the establishment of a dynamic model. Finally, a computer simulation is carried out, and finally the linear operation is performed. The results are compared with the turning operation results. Analyzed the turning problem of the large-incline belt conveyor and the structural characteristics of various turning methods, studied the design theory of the turning section of the flat-turning large-incline belt conveyor, and obtained the force analysis of the flat-turning large-incline belt conveyor Method and design approach of turning radius, the calculation method of load distribution coefficient of plane turning conveyor is analyzed, and the design calculation process of plane turning high-incline belt conveyor is given through actual engineering projects.

Although the demand for flat-turning and high-inclination belt conveyors continues to increase, the promotion of domestic flat-turning and high-inclination belt conveyors is relatively slow. The main reason is that theoretical research and technology are not perfect and mature enough, and users have insufficient knowledge of this conveyor.
