液压式双柱汽车举升机设计
摘要
双柱式汽车举升机是一种汽车维修和保养单位常用的举升设备,广泛硬用于轿车等小型车的维修和保养。目前,全国生产汽车举升机的厂家较多,生产的举
升机的形式也比较繁多,有双柱式举升机、四柱式举升机、剪式举升机、组合动动式汽车举升机。
本文较全面地介绍了举升机的分类,在确定了所要设计的举升机的方案之后,即针对举升机的结构及其特点要求进行了设计与说明,同时对举升机设计过程中所涉及到的工艺性问题进行补充说明。然后分析了液压式双柱汽车举升机主立柱的截面特性,并对主立柱的强刚度和托臂的强度进行了校核验算。对液压缸活塞杆强度以及受压杆的稳定性也进行了验算,以保证所设计的举升机满足使用的要求。
本课题所设计的式液压驱动式的普通式双柱汽车举升机。它的特点是:(1)性能可靠,低能耗,操作方便;(2)无横梁,结构简单;(3)非对称托臂可伸缩,保证了安全性;(4)托脚的最低位置低,使得车辆的底盘可以比较低,对各种车辆的使用性扩大了;(5)与螺杆式举升机相比,使用的寿命较长;(6)价格低廉,拥有的市场份额大。

Two pillar car lift
ABSTRACT
Two pillar car lift is a car repair and maintenance mon lifting equipment, extensive hard for car repairs and maintenance of small cars. At present, producing more lift manufacturers, production of lift are in the form of numerous, double-column lift, four-column lift, scissor lift, combo move-car lift.
prehensive introduction of the classification of the lift, in determining the design for lift after the programme, that is, for structure and characteristics of lift requirement is designed and documented, at the same time on the design process involved in the process of lifting a supplementary explanation of the problem. And then analyzed for ordinary dual-cylinder vehicle lift section of the main column properties, and on the main column strength and stiffness and strength of the support arm of the checking and checking. On the strength of hydraulic cylinder piston rod as well as checking pression Rod stability is also to ensure that the design of the lift meet the requirements of. Design of hydraulic drive-the present subject for ordinary dual-cylinder vehicle lift.
It of features is: (1) performance reliable, low energy consumption, operation convenient; (2) no beam, structure simple; (3) non-symmetric supporting arm can telescopic, guarantee has security; (4) s
