Description
Technical Field
The invention belongs to the technical field of high-speed conveying of belt conveyors, and particularly relates to a carrier roller set of a high-speed belt conveyor.
Background
The belt conveyor is a main bulk material transportation tool at present, the most common running speed of the belt conveyor in China is 2-2.5 m/s, the highest speed is 6m/s, the speed of the belt conveyor in foreign countries reaches 7-12 m/s, the highest speed of the German belt conveyor exceeds 15m/s, and the belt conveyor is developing towards the direction of large transportation volume and high belt speed. With the increase of the belt speed, the original less obvious deviation is realized under the low-speed condition, and even the negligible transverse vibration dynamic characteristics of the conveying belt are very prominent, so that the running effect of the belt conveyor is seriously influenced. Although the rotating speed and the sealing of the carrier roller bearing are greatly improved, the vertical movement of a conveying belt up and down between carrier rollers in the high-speed conveying process, namely the transverse vibration, cannot be reduced, and meanwhile, the belt speed is increased, the deviation time is shortened, and the response time of an original belt conveyor deviation adjusting device cannot meet the high-speed operation requirement, so that a carrier roller group suitable for the high-speed belt conveyor is urgently required to be developed.
Disclosure of Invention
The invention aims to solve the problems of a high-speed belt conveyor, and provides a carrier roller group of the high-speed belt conveyor, which adopts the following technical scheme:
a carrier roller group of a high-speed belt conveyor comprises horizontal carrier rollers, outward-inclined side rollers and inward-inclined vertical rollers which are arranged on a rack, three outward-inclined side rollers and an inward-inclined vertical roller are respectively arranged on two axial sides of one horizontal carrier roller, the diameter of one outward-inclined side roller in the three outward-inclined side rollers is 60-70% of that of the horizontal carrier roller, the diameter of the other two outward-inclined side rollers is 70-80% of that of the outward-inclined side roller, a central line between two outward-inclined side rollers with smaller diameters in the three outward-inclined side rollers is aligned with the axis of the horizontal carrier roller, the distance between the axes of the two outward-inclined side rollers with smaller diameters is smaller than that of the horizontal carrier roller, the outward-inclined side rollers with larger diameters on two axial sides of the horizontal carrier roller are respectively arranged on two radial sides of the horizontal carrier roller to form an asymmetrical arrangement, the inward-inclined vertical rollers are arranged above the outward-inclined side rollers with larger diameters, the roll shafts of the horizontal carrier roller are fixedly connected to the rack through a hinge connecting rod L, the hinge connecting rod of the vertical carrier roller, the vertical roller, the connecting rod is connected to the rack through a hinge connecting rod L, the hinge connecting rod of the vertical roller, the connecting rod of the vertical roller, the vertical roller is connected to the vertical roller, the vertical roller is connected to the vertical roller through a connecting rod of the vertical roller, the connecting rod of the connecting rod, the connecting rod of the connecting rod, the connecting rod connecting.
The belt deviation correcting device has the advantages that the diameter of the outward-inclined side rollers is small, the number of the outward-inclined side rollers is large, so that the contact area of a belt and carrier rollers is effectively increased, the transverse vibration in the high-speed conveying process is reduced, the jamming is avoided, the vertical movement of the conveying belt can be reduced in the high-speed operation process by adopting a split asymmetric structure, the conveying belt can be prevented from being clamped between the carrier rollers when the conveying belt deviates, the spring is adopted for constant pressure automatic deviation correction, under the action of a reset spring, when the conveying speed changes or the load weight changes, the groove angle can automatically change, the centering capacity and the anti-skidding capacity in the high-speed or heavy-load conveying process are improved, when the belt deviates to one side, the pressure applied to the lower portions of the outward-inclined side rollers on the side is increased greatly, the inclination angle of the outward-inclined side rollers is changed due to the fact that the middle positions of the support plates are hinged to the support rods, the clamping between the outward-inclined side rollers and the horizontal carrier rollers is small, the deviation restoring force of the deviation conveying belt to the deviation conveying belt is generated, and when the belt deviates to one side vertical roller, the side rollers, the inward-inclined side vertical rollers are pushed to move outwards by.
