[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] In areas of my country with harsh terrain, cable-suspended belt conveyors are a popular option. However, during conveying, these cables experience a "pendulum"-like displacement due to factors such as material, belt tension, wind, rain, and snow. Because their structure differs from conventional belt conveyors, excessive wind vibration can cause material scattering, structural stress changes, and other anomalies. These hazards not only disrupt the normal operation of the belt conveyor but, in severe cases, can result in economic losses and even safety accidents.

[0004] The wind-induced vibration monitoring system for suspension belt conveyors is a method for real-time monitoring of wind-induced vibration data of suspension belt conveyors. The detection benchmark is an important component for wind-induced vibration offset detection. Reasonable setting of the benchmark helps to improve the accuracy of wind-induced vibration offset detection and ensure the safe operation of the suspension belt conveyor under wind-induced vibration conditions.

[0059] It should be noted that the length dimensions of the clamping plate bottom plate and the clamping plate top plate should be determined according to the distance between the rope gripper at the bottom of the H-shaped hanger 8 of the suspension belt conveyor and the hanger, and the width dimension of the clamping plate should be determined according to the size of the bottom crossbeam of the H-shaped hanger 8 of the suspension belt conveyor; its thickness is not less than the wall thickness of the selected material of the connecting rod 7; the length of the connecting rod 7 should be determined according to the distance between the upper part of the main rod 1 and the lower part of the bottom crossbeam of the H-shaped hanger 8; the connecting rod 7 can preferably be a rectangular pipe, and the specification should be determined according to the dimensions of the clamping plate bottom plate and the clamping plate top plate, and the dimensions required for the reserved bolt holes should be reserved.

[0060] In this embodiment, specifically, the wing plate 2 is a thin steel plate with a fixed length and width.

[0061] In this embodiment, specifically, the length of the wing plate 2 is 1000 millimeters, and the width is set according to the specific monitoring scenario; it should be noted that the width of the wing plate 2 should be greater than the detection accuracy requirement of the monitoring system, and the wing plate 2 cannot interfere with the bottom of the maintenance trolley 9 of the suspension belt conveyor.
