储柜横跑车运输带传动链张紧装置改进

Improvement of the Drive Chain Tensioning Device for the Storage Cabinet Horizontal Carriage Conveyor Belt

摘要: 针对日常维护更换调整储柜横跑车运输带传动链时，其张紧装置、安装设计缺陷没有张紧调节位置，张紧装置靠近主传动链轮过近并且没有调整位置，主传动链轮。被动链轮位置是固定的，导致传动链张紧位置受限的问题，对储柜横跑车运输带传动系统原理、结构进行分析提出改进方案，通过“摆臂式张紧 + 张紧轮定位功能”的思路，制作并加工了摆臂、轴套、定位底座、和原张紧链轮、链轮轴、轴承，同时选用连接螺栓、定位螺栓，锁紧螺母等标准件，最终上机组装储柜横跑车运输带传动链张紧装置，应用后有效提升了传动链张紧度调节的范围及维修效率，降低了传动链的更换频次，降低了维修人员工作量的同时也有效节约了维修成本，提升了设备运行效率与可靠性。

Abstract: During routine maintenance and replacement of the storage cabinet horizontal carriage conveyor belt drive chain, the tensioning device and installation design flaws lacked a tension adjustment position. The tensioning device was too close to the main drive sprocket and lacked adjustment, leaving the main drive sprocket and passive sprocket fixed, resulting in a limited drive chain tensioning position. This study analyzed the principle and structure of the storage cabinet horizontal carriage conveyor belt drive system and proposed an improvement plan. Using the concept of “swing arm tensioning + tensioner positioning function”, the swing arm, bushing, positioning base, and the original tensioning sprocket, sprocket shaft, and bearing were fabricated and processed. Standard parts such as connecting bolts, positioning bolts, and lock nuts were used, and the storage cabinet horizontal carriage conveyor belt drive chain tensioning device was finally assembled on the machine. This application effectively improved the drive chain tension adjustment range and maintenance efficiency, reduced the frequency of drive chain replacement, reduced maintenance personnel workload, and effectively saved maintenance costs, thereby improving equipment operating efficiency and reliability.
