Description

Technical Field

[0001] The utility model relates to the technical field of fault detection equipment, in particular to a roller fault detection device. Background Art

[0002] Long-distance belt conveyors are characterized by low operating costs, simple operation, high efficiency and long transportation distances. They are important tools for transporting bulk materials. However, various types of failures may occur during the operation of long-distance belt conveyors (especially long-distance belt conveyors, which are evenly spaced with numerous rollers. The rollers are rotatably connected to the beams on both sides of the belt conveyor to lift the upper end of the conveyor belt. However, the bearings at the rotating connection between the rollers and the beams are easily damaged. Once the bearings are damaged, the corresponding rollers will make obvious abnormal noises when rotating) and there are safety hazards.

[0003] Application number: CN202222037956.1 discloses a belt conveyor roller fault detection device for detecting whether there is a fault in the belt conveyor roller, including a data collector, a controller, a human-computer interaction module and multiple sound collectors. The multiple sound collectors are arranged on the side of the belt conveyor and are spaced apart along the conveying direction of the belt conveyor. The multiple sound collectors are electrically connected to the controller through the data collector, and the human-computer interaction module is electrically connected to the controller. In this way, the sound collector collects the noise emitted by the belt conveyor during operation, and the controller processes and analyzes the collected noise to determine whether the belt conveyor roller is damaged. If there is damage, the human-computer interaction module outputs it.

[0004] The existing roller fault detection device detects abnormal sounds at the roller by sound collection as a reference for judging whether the roller is faulty. If there are obvious signs of damage such as scratches, wear marks, cracks, deformation, bubbles, stains or damage on the surface of the roller, the operation of the conveyor belt will inevitably be affected. At this time, the sound at the roller may not produce large abnormal noise, which affects the accuracy of roller fault detection. In addition, the sound collector of the roller fault detection device is far away from the roller, which affects the accuracy of roller sound fault detection. For this reason, we propose a roller fault detection device. Utility Model Content
