Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited by the embodiments.

[0018] Such as figure 1 As shown, the detection method of belt conveyor slippage and broken belt, the actual belt speed value will be detected by the driving roller speed sensor 4 and the driven roller speed sensor 5 installed on the driving roller and driven roller of the belt conveyor Send to PLC1, PLC1 compares the difference between the actual speed value measured by the driving roller and the actual speed value measured by the driven roller with the preset slippage value or broken belt value, and judges the running status of the belt conveyor 6 according to the comparison result , when the difference is greater than the slippage value but less than the broken belt value, it is judged that the belt is slipping, at this time PLC1 sends an alarm signal to the sound and ligh...

Abstract

The invention relates to a belt conveyor slippage and fracture detection method. A driving roller speed sensor arranged on a driving roller of a belt conveyor and a driven roller speed sensor arranged on a driven roller of the belt conveyor send detected actual speed values of the belt to a PLC, the PLC compares the detected actual speed values of the driving roller and the driven roller, the obtained difference is compared with a preset slippage value or fracture value, and the operating state of the belt conveyor is adjusted in dependence on the comparison result. When the difference is larger than the fracture value, the PLC automatically stops the belt which is broken down on site, and carries out interlock protection to upstream and downstream equipment. The belt conveyor slippage and fracture detection method is advantaged in that the detection method can be effectively used for detecting belt slippage and fracture, if a fault occurs, a fault signal is automatically sent to the PLC, the PLC carries out automatic shutdown or sound-light alarm to the corresponding belt on site, and industrial control is relatively accurate and in time.

Description

technical field [0001] The invention relates to the technical field of belt conveying, in particular to a detection method for belt conveyor slippage and broken belt. Background technique [0002] In the industrial production line, the belt conveyor is the main equipment for conveying materials, and plays a key role in connecting the preceding and the following. The normal operation of the belt conveyor is related to the smooth operation of the entire production line. If the belt slips or breaks, the material on the belt conveyor will continue to accumulate, causing material blockage in upstream equipment and material loss in downstream equipment, seriously affecting production line operations. However, because the production line is generally long and the structure is complex, it is not easy to detect in time when the belt conveyor slips or breaks, which often results in material blocking and breaking. This requires a detection method that can accurately detect the phenom...
