Symmetrical Drive Scissor Lift Platform Design And Research

With the rapid development of China's manufacturing industry, the lifting platform has become an important part of the automated production line.Enterprise production scale expanded research platform on a limited production line space is under more load is of real significance.This paper is to mainly study to the lifting platform in the unit by the board device in the copper electrolysis anode plate. According to the design and application requirements, The first of two kinds of schemes which is apply more extensive level driver fork lift platform, cut hinged single cylinder to drive cut fork lift platform is to kinematics and mechanics analysis.It is Proposed four-cylinder symmetrical drive overloaded scissor lift platform design and mechanical analysis of the lifting platform which come to the cylinder driving force simply hinged single cylinder drive scissor lift platform1/4. If the four cylinder mounting included angles with the horizontal line is equal, intermediate hinge shaft shear stress calculation for zero,It is very helpful for heavy load condition, and the main components for the parameters determination and strength check.Based on the hydraulic sync system analysis, it is proposed with synchronous valve hydraulic sync system to ensure that the four hydraulic cylinder of synchronous movement. It is used SolidEdge on the lifting platform and main parts for3D solid modeling, entity model into ANS YS to make the finite element analysisAt the end of the lifting platform in the starting position is the worst condition of the main structure of the finite element strength analysis. On sliding bearing spring unit is processed, the structure of the stress distribution of the system, the main structure of the stress within190MPa in full load condition. Lifting platform mainly structure stress analysis is after the maximum value of45steel yield stress range. From the analysis result, it is obtained satisfactory results and symmetrical driving heavy-duty scissor lift platform structure strength according to design requirements.Along with the rapid development of automation, it is used of heavy lifting platform face.and constantly expand service areas. Method of this research has certain practical value and wide applicability for similar structure design and structure modification of great use for reference.
