(1) In the turning section, the smaller the distance between the idler rollers on the load-carrying and return paths, the easier it is to make adjustments and fine-tunings later, and the more stable the operation of the conveyor belt. But it cannot be too dense, otherwise the resistance increases, causing the bending radius to increase. Based on experience, the spacing Z between the idler rollers on the load-carrying branch is generally set at 0.75–1 m, while the spacing between the idler rollers on the return branch is 1.5–2 m. Since the standard frame length for underground belt conveyors is generally 3 meters per set, the frame length needs to be modified accordingly in consideration of the support angle and the inward curve elevation angle y. (2) When an increased trenching angle and an inward curve elevation angle y are used for the turning section, a transition section is required before and after it; in this transition section, values of =1m and =2m are generally adopted, while the elevation slope on the inner side of the frame is usually set at 5‰ to 8‰. (3) Since the measures taken at the turn are the installation of a support angle and an inner curve elevation angle y, the former is a necessary condition while the latter depends on the situation; therefore, choosing the appropriate value is important, with a value of 0.5 being commonly used. , with a maximum of no more than l. ； ), = 0～5. , with a maximum of no more than 7. . (4) A certain amount of swing must be allowed for the axes of the carrying idler rollers and the return idler roller sets on the mounting frame. The planar bending belt conveyor is a type of belt conveyor that changes direction naturally, designed based on the principles of mechanical equilibrium. It features a simple structure that makes maintenance easy, and it is suitable for use in curved tunnels. By reducing the number of transfer points, it increases the safety factor. It represents a new, efficient type of coal mining transportation equipment that is well-suited to the actual conditions in underground mines, and it holds great potential for further development.
