Research On Continuous Replacing Device Of Belt Conveyor

Conveyor belt is the carrier of material transportation, there is frictionbetween the belt surface,the materials,belt and drum and the coal or ganguecrush after a period of time,which caused the conveyor belt surface scratch, wirerope corrosion and fracture.In order to ensure the normal operation conveyor,conveyor belt need to replace for regular. The present measures replacing belthave mainly artificial and mechanical measures, with discontinuous,need moreworkers,safe hidden troubles in the change operation. Therefore a kind of highefficiency, high safety belt replacing device need design to meet the mineproduction and transportation demand.This paper firstly based on analyzing working condition and main designparameters of belt replacing device and the different transportation situation ofbelt conveyor,the total scheme is designed.Each unit in the composition of thedevice,structure features and working principle are introduced in more detail inthis scheme.The three-dimensional modeling software SOLIDWORKS wasused to build three-dimensional model. The replacing technological process alsowas analyzed.Secondly, hydraulic system of the continuous replacing device was designed and each loop workflow was analyzed.Introduced the hydraulicsystem simulation software AMESim and the modeling and simulation of thehydraulic part was completed with the AMEsim Software. With the analysis ofthe dynamic characteristics, the feasibility of the hydraulic part wasillustrated.The key performances of belt locking, synchronization anddriving-tension,were also studied in this paper.At last, the industrial experiment of the belt replacing device was done inthe work site.The test result indicate that, the experiment performance is reliable,also can fulfill the need of the modern mine.
