Study On Structure And Performance Optimization Of Combined Roller Clearer

Winter snowfall is common in northern China,especially in the northeast.The newly fallen floating snow is repeatedly crushed by vehicles and pedestrians,which is easy to form compacted ice and snow,resulting in smooth roads,which is very easy to cause serious traffic accidents.It will cause urban traffic stagnation,railway network suspension,and capital airport closure,which will seriously affect people’s living conditions and industrial and agricultural production,and cause serious damage to the national economy.Until now,there is still a serious shortage of professional equipment to fight compacted ice and snow in China,and the traditional manual deicing and snow removal not only consumes a lot of financial and material resources,but also has low efficiency,less removal,and there are potential safety hazards in the process of removing compacted ice and snow,and it is very important to develop multi-functional snow plowing equipment suitable for China’s national conditions.Analyze the physical properties of pavement compacted ice and snow.The mechanical analysis of ground compacted ice and snow is divided into the force experienced by the rolling tool when cutting into the compacted ice and snow,and the resistance of the compacted ice and snow to the snow removal device is calculated by using the shear strength,and analysis of damage criteria for compacted ice and snow.Determination of a multifunctional roller snow removal device with ZL50 as a loader.The design of the roller and snow shovel of the multi-functional roller snow removal device,the calculation and analysis of the motion state and tangent working resistance of the roller,the vibration damping function of the roller,and the design and arrangement scheme of the roller tool.The schematic diagram of the hydraulic system is designed to explain the principle of the loader rising and falling,determine the working pressure of the hydraulic system,determine and select the main component parameters of the hydraulic cylinder,and determine the most suitable hydraulic cylinder.The finite element software is used to analyze the key components of the rolling device.Carry out static analysis of the support plate of the roller to see whether the strength of the support plate meets the requirements.A 6th-order modal analysis was performed on the roller to see if the mill resonated.The transient analysis of the rolling tool is to use the 16Mn and No.45 carbon steel materials of the rolling tool to carry out the transient analysis of the compacted ice and snow,and analyze the instantaneous cutting of the two material tools into the different simulation structures of the two materials of the compacting ice and snow tools.The hydraulic simulation software was used to analyze the simulation analysis of the lifting hydraulic system of ZL50 loader.The hydraulic simulation software is used to model and set the parameters of the hydraulic system of the loader,analyze the pressure loss of the inlet pipe of the hydraulic system,the displacement of the hydraulic cylinder,the speed of the hydraulic cylinder and the pressure of the rodless cavity of the hydraulic cylinder,and analyze the hydraulic system of the loader.
