Abstract

The invention discloses an automatic tensioning system of a belt conveyor and applications thereof. The automatic tensioning system comprises a tensioning device, a speed collecting device, a tension sensor and an electronic control system, wherein the tensioning device and the speed collecting device are installed on the tension roller of the belt conveyor, the tension sensor is installed under the driving roller support of the belt conveyor, and the electronic control system takes a PLC (Programmable Logic Controller) controller as a core. Through the proportional relation existing between current and load, the automatic tensioning system identifies the loading capacity on a conveying belt and detects the traction needed by the system converted by signals in the PLC. Then, the traction is compared with the tension detected by the tension sensor, and the compared result controls a trailer wagon to go forward or draw back. The tension position of the conveying belt is in a dynamic control process and provides the necessary tension of normal running for the conveyor to prevent slipping, so that the long-distance timely intelligent dynamic tensioning for the conveying belt is realized.

Description

technical field [0001] The present invention relates to belt conveyors. Background technique [0002] At present, the belt conveyor is one of the most important means of transportation for conveying bulk materials, because it can realize continuous loading and unloading of materials and has long transportation distance, large conveying capacity, low power consumption, relatively low investment cost and convenient maintenance. And other characteristics, so it is widely used in the material transportation of ports, docks, metallurgy, thermal power plants, open-pit mines and underground coal mines. Belt conveyor is a modern large-scale transportation equipment with high strength, large capacity and high power, and plays an important role in the national economy. [0003] Belt conveyors are equipped with tensioning devices. Existing tensioning device is made up of frame, tensioning drum, traction oil cylinder, tensioning winch and pulley block. The disadvantages are: the equi...
