Description

Bucket elevator with buffering hasp

Technical Field

The invention mainly relates to the technical field of elevators, in particular to a bucket elevator with a buffer lock catch.

Background

The bucket elevator is a continuous conveying machine for vertically lifting materials by utilizing a series of hoppers uniformly and fixedly connected to an endless traction member, and the bucket elevator is divided into three types, namely a loop chain, a plate chain and a belt, for vertically or nearly vertically conveying bulk materials upwards by utilizing a series of hoppers fixedly connected to a traction chain or a rubber belt.

If the materials in a part of the hoppers are not discharged, power failure or other faults occur, the transmission device stops running, and at the moment, the hoppers hung on the two sides of the upper roller rapidly fall under the action of gravity to reverse due to unequal weight. This reverse rotation phenomenon may cause a large impact load, and even a screw is pulled out or a hopper is partially detached. The existing non-return structure directly blocks the driving wheel by using non-return spines so as to stop the reverse rotation of the driving wheel, but when the elevator stops rotating reversely, the gravity and the speed of the side containing materials are very high, the impact on the driving wheel at the moment of locking is very high, and the driving wheel is easy to damage.
