折臂式高空作业车回转工作台的设计

Design of slewing working platform of folding boom aerial work vehicle

随着交通、建筑、煤矿等建设需求的不断增加,作业场合变得越来越复杂,作业难度也随之增加,对高空作业车的性能和功能要求也越来越高。为此,为应用较为广泛的折臂式高空作业车设计了回转装置,以单轴支承装置为主体,设计上、下托架结构,并进行有限元分析,以检验上下托架的结构强度和刚度是否满足要求,同时,对小臂受力变化后的受力分析也进行了计算。回转装置的设计使折臂式高空作业车在复杂作业环境中能顺利作业,并极大地提高了作业效率。

With the increasing demand for infrastructure construction such as transportation,architecture,and coal mining,the workplace has become more and more complex,and the operation difficulty has also increased,and the requirements for the performance and function of aerial work vehicles have also become higher and higher.For this reason,a slewing device is designed for the folded-arm aerial work vehicle,which is widely used.The upper and lower bracket structures are designed with the single-axle support device as the main body,and the finite element analysis is carried out to check whether the structural strength and stiffness of the upper and lower brackets meet the requirements.At the same time,the stress after the force change of smallboom is analyzed.The design of the rotary device enables the folding boom aerial work vehicle to smoothlywork in a complex working environment,which greatly improves the working efficiency.
