A belt tension monitoring system

Abstract

The invention provides a belt tension monitoring system, comprising a tension trolley, a three-dimensional camera and a controller; the tension trolley is connected to a belt conveyor through a belt whose tension is to be monitored; the tension trolley changes with the belt tension The 3D camera is set on one side of the tensioning trolley to monitor the position change of the tensioning trolley and transmit the 3D image data of the position change to the controller; the controller calculates the relationship between the tensioning trolley and the 3D camera according to the 3D image data. Check the straight-line distance between them and judge whether the straight-line distance is within the normal threshold range; if so, the belt is normal; if not, the belt is abnormal, and the controller controls the belt conveyor to stop. The invention proposes a tension trolley monitoring device based on three-dimensional video technology. By monitoring the positional relationship of the belt tension trolley in real time, and according to the rigid connection attribute, the preset safety belt tensioning displacement interval value is used to assist in judging whether the belt tension is correct or not. If abnormal, realize real-time quantitative monitoring of belt tension.

Description

technical field [0001] The invention relates to the field of monitoring, in particular to a belt tension monitoring system. Background technique [0002] The existing belt tension monitoring device mainly relies on the limit devices at both ends of the belt running range to adjust the belt tightness. It will be adjusted, and the belt tension is in an unsafe state near the limit, so the existing belt tension monitoring device cannot monitor whether the belt tension is within a safe range in real time, so that the belt tension It is impossible to alarm or stop when it exceeds the safety range, so that it is impossible to avoid excessive tension, slack or breakage of the belt, resulting in material spillage or even more serious transportation accidents. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a belt tension monitoring system, which can monitor the belt tension in real time. [0004] For achieving the above object, the present inv...
