液压反铲装置设计

structure feature is between components All adopt the connection by oil cylinder hinged adjustableto realize the various movements excavation.Moving arm little hinge point and rotary platform,andwith hinged arm oil cylinder to support and change the dip Angle,through arm arm Oil cylindertelescopic can make moving arm around small hinge point lifting rotation.Dou lever arm hinged onthe upper arm,dou rod and the relative By dou pole position to control oil cylinder,when dou rodoil cylinder telescopic,dou lever arm can be around the upper energizer hinge point rotation.Bucketand measures Rod front-end loader,and through hinged cylinder telescopic made the bucket turningaround the point.To increase the bucket corner,usually by connecting rod Institutions and bucketconnection.theperformance good,and may make the high speed reverse,the transmissionsteady,structure simple,may absorb attacks and vibrates,the operation reduces effort,and to be easyto realize the automated control,is easy to realize the standardization,the seriation,theuniversalization.This designed main parameter is scoop capacity 0.2m,it is long to the middle andsmall scale hydraulic excavator,mainly design the excavator's the work installment and thehydraulic transmissionprinciple.In the design,used marching walked the installment to satisfied request.Upside the turnplate isthe entire rotation,thereof it may work in a greater scope.And further because uses thehydraulicsteering to enable the entire machine performance to improve.Compared with themechanical type excavator,its excavation strength enhance to 2~3 times,the entire machineweight approximately is 5 tons,the excavation strength approximately is 30kN,the biggestunloading high approximately is 2.65m,biggest digging depth is 4.2m,the biggest excavationradius approximately is 5.728m,thus can see the entire machine work ability to have the very bigimprovement,not only excavation strength big,but also machine weight light,transmission steadyly,work efficiency is high,the structure is compact.Moreover,but also proposes to the excavator workinstallment based on the structureinference organization plan innovation design method.Key word:Hydraulic pressure excavator Excavation organization Hydraulic systemInnovation designSignature of supervisor:
