Gantry Bucket Wheel Reclaimer Of A Blender Mechanism Research And Improvement

Bucket wheel stacker-reclaimer was derived and developed from bucketwheel excavator, it is a new type of high efficiency continuous loading andunloading equipment. Bridge-type blending bucket wheel reclaimer is one of themain branches of bucket wheel stacker-reclaimer. It was widely used in steelmills, docks, building materials, non-ferrous metal, chemical industry, powerplant and other departments to homogenize raw material. With the continuousdevelopment of blending reclaimer, foreign mines and terminal also used bridgetype blending reclaimer for iron ore homogenization processing, in order toimprove the added value of iron ore. Bucket-wheel mechanism is mixbridge-type bucket wheel reclaimer body， Bucket wheel agencies usefrequently，Working conditions is poor，So the failure rate is relatively high，Bucket wheel mechanism failure after the entire device can’t work，it Will affectthe whole yard system.In this paper, we study the bridge type blending bucket wheel reclaimer isused in steel mills blending yard， After using about half a year, the bridge-typeblending bucket wheel reclaimer’s track and support rolling contact surface areground into wavy, leads to the vehicle vibration, and then the equipment can notdo normal operation. According to this problem，Based on the analysis of bucketwheel reclaimer Picking process，Put forward a kind of resistance, which isdifferent from traditional average mining algorithm，obtained that diggingresistance in the process of reclaiming was the wavy change，rather than a fixedvalue。Then set up the bucket wheel model in Solidworks software, Imported itto ANSYS Workbench software and analyze the friction between the wheel andrail, To analyze the cause of friction appear wavy and Propose solutions. For thecase finite element analysis was carried out on the structure, aims at solving theproblem of frequently rail damage, making a design more reasonable and highservice life of the bucket wheel institutions.
