Adjust the belt of the belt conveyor bearing the idler group in the middle of the whole belt conveyor, and adjust the position of the idler group to adjust the deviation when the idler group deviates; During manufacturing, the mounting holes on both sides of the idler gear set are machined into long holes for adjustment. There are many types of self-aligning idler groups, such as intermediate shaft type, four-bar type and vertical roller type. Its principle is to stop the rotation of the idler in the horizontal plane or generate lateral thrust to automatically center the belt, thus adjusting the belt deviation.

The adjustment of driving roller and reversing roller is an important link in the adjustment of belt deviation. Because a belt conveyor has at least 2 to 5 rollers, the installation position of all rollers must be perpendicular to the center line of the belt conveyor in the length direction. If the deflection is too large, deviation will inevitably occur.

Extended data:

Preventive measures for belt conveyor deviation;

1, strengthen management, keep the roadway clean, there is no floating coal, no water, no oil and no sundries on the tape, and there is no coal pile at the nose and tail. Improve the quality of operation and maintenance personnel and keep the conveyor in good running condition.

2, keep clear of coal dust in the main parts of the conveyor roller, idler and receiving place. , to prevent the belt from running off due to the coal dust on the roller and idler.

3. Adjust the deviation of the tape in time, check the abrasion of the edge and joint of the tape in time, and replace and repair it in time when problems are found.
