Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, and particularly relates to a tape break warning device for a bucket elevator. Background Technique

[0002] A bucket elevator is a commonly used vertical conveying device. It uses a series of hoppers uniformly fixed on an endless traction member to lift materials upward in a vertical or nearly vertical direction. After the bucket elevator operates for a long time, the steel wire core of the tape is very likely to break at the clip of the tape joint. If it cannot be discovered and processed in time, the broken steel wire cores will become more and more over time. When the strength of the remaining steel wire ropes is insufficient to bear the load of the elevator, it will cause the sudden break of the elevator tape and result in an accident of the elevator falling off its frame. When the existing tape detection device is installed, it is fixed by fixing bolts. Long-term use will cause the fixing bolts to rust and slip, affecting the detection effect.

[0003] According to what is described in a tape break warning device for a bucket elevator (the authorized announcement number is: CN209321776 U) published on the patent network, this tape break warning device for a bucket elevator includes a "detection module, a lifting platform, a lifting bracket", etc. to detect the tape.
