随着港口煤、矿等散装物料吞吐量的不断增加,港口中拥有了大量的散料装卸机械、皮带输送机等设备,而堆取料机已作为港口码头散料堆场的重要堆取设备,回转支承作为堆取料机的重要零部件,对于设备的可靠性和使用率有着极大的影响。回转支承安装在门座架之上,支承着回转平台、塔架(立柱)、臂架、斗轮、皮带机、配重、回转机构等上部结构,实现臂架的回转功能。目前,堆取料机常用的回转支承主要有回转台车与回转轴承两种形式。
With the continuous increase in the throughput of bulk materials such as coal and mines in ports, the port has a large number of bulk loading and unloading machinery and belt conveyors and other equipment, and the stacker and reclaimer has been used as an important stacking device for bulk terminals in the port , Slewing rings as an important part of the stacker reclaimer, has a great impact on the reliability and utilization of the equipment. Swivel support installed on the door frame, supporting the revolving platform, the tower (column), boom, bucket wheel, belt machine, counterweight, slewing mechanism and other superstructure, to achieve boom rotation function. At present, the rotary support commonly used in stacker-reclaimer mainly includes two types of rotary trolley and slewing bearing.
