With the rapid development of modern social science and technology,long-distance,large capacity,and high-power belt conveyors have become the main development trend,and tensioning devices are an indispensable part of the normal production and operation of belt conveyor systems.By installing a tensioning device,it is ensured that the conveyor belt has good tension,thereby avoiding slipping caused by too little friction between the conveyor belt and the drum.The failure of the tensioning device is one of the faults of belt conveyors,often causing belt wear and material spillage.In severe cases,it can lead to belt breakage,equipment shutdown,etc.The losses caused by such accidents are difficult to estimate.In order to reduce the harm caused by the failure of the tensioning device and maximize the economic benefits of the belt conveyor during operation.This article takes a heavy hammer tensioning device as the research object,and uses SolidWorks as the support platform to develop an automated drawing software that integrates load calculation,component modeling,and component assembly.The research content of this article is as follows:(1)Using database management technology,establish a standard type spectrum database for tension device components in the DTⅡ(A)belt conveyor manual in the database management system SQL Server.Using Visual Basic 6.0as the development platform,apply a certain case to calculate the required tension value.Next,modular and parameterized technologies are applied,and SolidWorks API is used to combine secondary development with database access technology(ADO)to establish a three-dimensional model of relevant components,completing the series design of components and the entire bottom-up assembly process.(2)By simulating the starting condition of the conveyor and using modal analysis,the natural frequency and modal shape diagram of the device are obtained.By analyzing the modal results,identify the parts of the structure that are susceptible to resonance,and then perform harmonic response analysis to make the device withstand loads of different frequencies,in order to determine the frequency at which resonance occurs and provide a theoretical basis for preventing resonance damage to the structure. |
