Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bulk material loading and unloading equipment, and in particular to an anti-turn-off device for a bucket wheel reducer. Background Technology
[0002] Bucket wheel stacker-reclaimers are continuous and efficient bulk material handling machines, commonly used in stacker-reclaim processes in strip-shaped material yards, greatly improving the efficiency of bulk material handling. The bucket wheel device is the main component of the bucket wheel stacker-reclaimer for completing the material handling operation. Material is picked up by the bucket, and as the bucket rotates, it is unloaded onto a cantilever conveyor belt via the bucket wheel unloading device. From there, it is unloaded through a central funnel onto a ground conveyor belt for transport. Continuous material handling is achieved through trolley travel, boom rotation, and bucket wheel rotation.
[0003] The bucket wheel drive unit consists of a motor, reducer, and hydraulic coupling. For ease of installation, maintenance, and disassembly, the bucket wheel shaft and reducer are typically connected via a hollow shaft spline. One end of the bucket wheel drive shaft is splined, and two semi-split ferrules are secured to the shaft. These ferrules are bolted to the reducer end face to meet the reducer's axial positioning requirements. Thus, the weight of the bucket wheel drive unit is borne by the spline and the two semi-split ferrules. However, due to the short axial connection length between the ferrules and the bucket wheel shaft, insufficient tightening torque during installation, or vibration during long-term operation causing loosening of the bolts, the reducer may experience axial movement. This can lead to grinding at the spline connection between the bucket wheel shaft and the reducer, damaging the spline connection and causing the reducer to turn around. This necessitates equipment shutdown and replacement of the bucket wheel shaft and reducer, impacting the overall equipment and the production efficiency of the bulk material handling process.
