Belt conveyor handling method
Jan 09, 2024
There are various reasons for belt deviation, which need to be handled differently according to the different reasons
Adjusting the carrier roller group
When the belt of the belt conveyor deviates in the middle of the entire belt conveyor, the position of the roller group can be adjusted to adjust the deviation; During manufacturing, the installation holes on both sides of the roller group are machined into long holes for adjustment. The specific method is which side the belt is biased towards, which side of the roller group moves forward towards the direction of the belt, or the other side moves backward. If the belt deviates in the upward direction, the lower position of the roller group should move to the left, and the upper position of the roller group should move to the right.
Install the centering roller group
There are various types of centering roller groups, such as intermediate shaft type, four link type, vertical roller type, etc. The principle is to use blocking or roller rotation in the horizontal plane to block or generate lateral thrust, so that the belt automatically moves towards the center to achieve the purpose of adjusting belt deviation. This method is generally more reasonable when the total length of a belt conveyor is short or when the belt conveyor is running in both directions, because shorter belt conveyors are more prone to deviation and are not easy to adjust. It is best not to use this method for long belt conveyors, as the use of the centering roller group will have a certain impact on the service life of the belt.
Adjusting the position of the drive drum and the directional drum
The adjustment of the driving drum and the redirecting drum is an important link in adjusting the deviation of the belt. Because a belt conveyor has at least 2 to 5 drums, the installation position of all drums must be perpendicular to the centerline of the length direction of the belt conveyor. If the deviation is too large, it will inevitably cause deviation. The adjustment method is similar to adjusting the roller group. For the head drum, if the belt deviates to the right of the drum, the bearing seat on the right side should move forward. If the belt deviates to the left of the drum, the bearing seat on the left side should move forward. Correspondingly, the left bearing seat can also be moved back or the right bearing seat can be moved back. The adjustment method of the tail drum is exactly the opposite to that of the head drum. After repeated adjustments until the belt is adjusted to the ideal position. It is best to accurately install its position before adjusting the drive or redirecting the drum.
Adjustment of tension
The adjustment of the belt tension is a very important step in adjusting the deviation of the belt conveyor. The two directional rollers at the upper part of the tensioning point of the heavy hammer should not only be perpendicular to the length direction of the belt, but also perpendicular to the gravity perpendicular line, ensuring that their axis centerline is horizontal. When using spiral tensioning or hydraulic cylinder tensioning, the two bearing seats of the tensioning drum should be translated simultaneously to ensure that the drum axis is perpendicular to the longitudinal direction of the belt. The specific adjustment method for belt deviation is similar to the adjustment at the drum.
