High-speed belt conveyor roller set

Abstract

The invention discloses a carrier roller set of a high-speed belt conveyor, belongs to the technical field of high-speed conveying of belt conveyors, and solves the problem of the high-speed belt conveyor. The carrier roller set of the high-speed belt conveyor comprises a horizontal carrier roller, outer inclined side rollers and an inner inclined side vertical roller which are arranged on a machine frame, wherein three outer inclined side rollers and one inner inclined side vertical roller are arranged on two sides of the horizontal carrier roller in the axial direction correspondingly, the diameter of one of the three outer inclined side rollers is 60%-70% of the diameter of the horizontal carrier roller, and the diameters of the other two outer inclined side rollers are the same and are70%-80% of the diameter of the outer inclined side roller; and the center line between the two outer inclined side rollers with smaller diameters among the three outer inclined side rollers is aligned with the axis of the horizontal carrier roller, the axis spacing of the two outer inclined side rollers with smaller diameters is smaller than the diameter of the horizontal carrier roller, and theouter inclined side rollers, with larger diameter, on the two sides of the horizontal carrier roller in the axial direction, are arranged on two sides of the horizontal carrier roller in the radial direction correspondingly, thus forming an asymmetric arrangement. The carrier roller set of high-speed belt conveyor is used for the high-speed belt conveyor.

Description

technical field [0001] The invention belongs to the technical field of high-speed conveying of belt conveyors, and in particular relates to an idler set of high-speed belt conveyors. Background technique [0002] Belt conveyor is the main bulk material transportation tool nowadays. At present, the most common running speed of belt conveyor in my country is 2-2.5m / s, and the maximum speed is 6m / s. The speed of belt conveyor abroad has reached 7~ 12 m / s, the maximum speed of the German belt conveyor has exceeded 15m / s, and the belt conveyor is developing in the direction of large capacity and high belt speed. With the increase of the belt speed, the inconspicuous running deviation at low speed conditions, and even the negligible lateral vibration dynamic characteristics of the conveyor belt are very prominent, which seriously affects the operation effect of the belt conveyor. Although the speed and sealing of idler bearings have been greatly improved, it is still impossible to...

AI Technical Summary

Problems solved by technology

With the increase of belt speed, the dynamic characteristics of the lateral vibration of the conveyor belt, which were not obvious under low-speed conditions, or even negligible, are very prominent, which seriously affects the operation effect of the belt conveyor.

Although the speed and sealing of the roller bearings have been greatly improved, it is still impossible to reduce the vertical movement of the conveyor belt running up and down between the rollers during high-speed conveying, that is, lateral vibration. The response time of the deviation adjustment device of the belt conveyor cannot meet the requirements of high-speed operation, so it is urgent to develop idler sets suitable for high-speed belt conveyors
