斗轮堆取料机臂架带式输送机张紧装置改进

Improvement on take-up device of boom belt conveyor of bucket-wheel stacker reclaimer

斗轮堆取料机在使用过程中易出现输送带失速现象,导致严重的堵料情况。分析其原因,是因为臂架带式输送机张紧力不足,以及张紧装置行程不够所造成。通过对其结构的研究分析,设计一种具有自动补偿功能的张紧装置。该装置的优点是在设备连续工作时,不需要频繁调节张紧装置,且能保证输送带在驱动滚筒上具有持续、足够的张力,确保设备运行良好。

The stalled belt during operation of the bucket-wheel stacker reclaimer results in severe material blockage. It is caused by insufficient belt tension of the boom belt conveyor and inadequate traveling distance of the take-up device. After the study on its structure, a kind of take-up device with automatic compensation function was designed. The take-up device was advantaged by needless frequent adjustment during continuous operation and keeping continuous and adequate tension, so as to ensure normal operation of the boom belt conveyor.
