AI Technical Summary

Technical Problem

The tensioning device of existing belt conveyors cannot automatically adjust the tension force, resulting in the inability to match the optimal tension under different working conditions, and unnecessary pulling of the conveyor belt during shutdown, increasing the risk of damage.

Method used

An automatic tensioning device for mining belt conveyors is designed, including a conveyor belt main body, a driving assembly and an adjustment assembly. The adjustment assembly can detect and adjust the tension force of the conveyor belt in real time through the cooperation of the up and down moving barrel and the sliding barrel, ensuring that the appropriate tension force is maintained under different working conditions.

Benefits of technology

Automatic adjustment of the tension force of the conveyor belt is achieved, ensuring that appropriate tension is maintained under different working conditions, avoiding unnecessary pulling of the conveyor belt during shutdown, reducing the risk of damage, and improving the operating efficiency of the conveyor.

Abstract

The invention relates to the technical field of belt conveyors, in particular to a mining belt conveyor automatic tensioning device which comprises a conveying belt body and driving assemblies, the driving assemblies are arranged at the two ends of the conveying belt body, and a conveying belt is arranged between the two driving assemblies in a sleeving mode. The driving assemblies are fixed to the two ends of the fixing frame. The two driving assemblies, the upper supporting cylinder and the lower supporting cylinder are sleeved with the conveying belt. An adjusting assembly is fixedly connected to the middle of the fixing frame and used for adjusting the tensile force of the conveying belt. By arranging the adjusting assembly, the tension of the conveying belt can be adjusted, so that the tension of the conveying belt is matched with conveyed materials; the rotating speed of the driving cylinders can be detected in real time by arranging the rotating disc and the sensor, so that the control system can simultaneously monitor whether the rotating speeds of the driving cylinders at the two ends of the conveying belt body are consistent or not, and whether the conveying belt slips or not and whether the tensioning force meets working condition requirements or not are judged; and when not working, the adjusting assembly restores to the non-working state, the tension force of the conveying belt is reduced, and therefore the conveying belt is prevented from being damaged.
