The Development Of Omni-directional Scissor Self-propelled Aerial Working Platform

Aerial working platforms is a kind of specific devices which transport staff, tools, equipment andmaterials to the desired location completing overhead work through stretch institutions, it is one of thespecial engineering machinery, which is widely used in construction, airport, residential and otherconstruction sites. Scissor self-propelled aerial working platform is kind of aerial working machinery,the bearing chassis of self-propelled aerial working platform mostly uses crawler or wheeled mobileoperators at present, making the suspension mechanism more complex and inevitable turning radius inmovement. In response to these problems, develop the omni-directional scissor self-propelled aerialworking platform; improve the motion pefermance of self-propelled aerial working platform. Theresearch work of this paper is as follows:Firstly, study the curve equation of the rollers, complete the design and manufacture ofMecanum wheel. Research the determination methods of Mecanum wheel rolling resistancecoefficient and study the law of rolling resistance coefficient through virtual prototype;Secondly, measure the sliding friction coefficient of the roller with the ground, establish thekinematic equation and dynamic equation with sliding of omni-derectional platform pursuant to whichdesign the control system of the platform, and complete the structural design and manufacture ofomni-derectional platform;Thirdly, study the kinematics of a single-cylinder V-propelled scissor lift platform, analyse thestress of the bottom scissor arm. Optimize the design of the scissor arm for the goal of reducing thehydraulic cylinder maximum thrust and scissor arm quality. Design the protecting plate and its liftingmechanism.
