Research on the control system of the multi-point driving belt conveyor tension device

摘要

The tensioning device is an important part of a large belt conveyor, and its performance is directly related to the safe operation and service life of the belt conveyor. This paper designs a hydraulic automatic tension device and electrical control scheme that provides the necessary tension for the conveyor to operate normally, establishes a multi-point drive belt conveyor tensioning device under different working conditions to establish a mathematical model, and uses MATLAB / SIMULINK to tension Simulate different systems under different operating conditions. The results show that the tensioning device can solve the key problems such as lagging dynamic load response to the conveyor belt and power imbalance in large conveyors under different working conditions. While reducing the use strength of the conveyor belt, the working efficiency of the belt conveyor is improved.
