While slipping, the frictional traction of the conveyor driven pulley is reduced, overloaded, or the conveyor belt is stuck. The decrease in frictional traction is due to muddy water on the conveyor belt or the driving pulley, and the tension of the conveyor belt has decreased.
If the driven pulley of the belt conveyor continues to slip and cannot be corrected, it will cause a serious safety accident when the conveyor is brought on fire. Conveyance with fire will not only cause huge economic losses to mine production, but also seriously endanger the lives of underground mine workers. Therefore, preventing conveyor pulleys from slipping and conveying with fire has been highly valued, especially for the underground mineral extraction industry.
In order to prevent the belt conveyor pulley from slipping and safety accidents caused by its friction factors. Belt conveyors for underground mines require safety protection devices.
1. Anti-slip protection, temperature protection and monitoring device for driving pulley;
2. Coal pile protection monitoring device in material unloading section;
3. Deviation monitoring and protection device for conveyor
4. Conveyor is equipped with roadway smoke protection and brake sprinkler;
5.Conveyor belt tension monitoring device
6. Other protective devices, etc.
The tube-type slip protection device generally installs the magnet of the sensor on the side of the guide pulley, and is mainly fixed by bolts. The sensor is installed near the guide roller. If the conveyor belt breaks or slips during operation, the speed of the guide roller will change. When the speed of the guide pulley through the sensor response reaches the set value, the protection device sends a signal to let the conveyor stops.
It mainly consists of a pulley sensor and a control box. During normal operation of the conveyor, the roller can maintain a certain speed under the drive of the conveyor belt, and the roller protection device will not start. When the belt breaks and slips, the speed of the conveyor belt is slowed down or stopped. When the roller speed reaches the set value, the protection device sends a signal to stop the conveyor.
