A0剪叉式平台
摘要
由于各行业的发展,针对升降平台服务的设备行业已经成为我国的新型产业不断发展壮大,各类剪叉式平台不断出现,随着质量的逐步提高,销量也在稳步上升。本设计液压升降台采用剪叉式结构。
近年来,有许多课题文献是有关于剪叉式液压平台液压系统的,但这些研究大多针对于某一课题或者难点进行研究,对于研究平台及液压系统的却少,所以研究与设计剪叉式液压平台及液压系统具有重要现实与理论意义。
本主要概述剪叉式平台液压技术的发展史及其目前在国内外发展情况,简述了剪叉式平台发展趋势,整机的液压系统图油路各自拟订好的控制回路及液压源而成。各回路相互时去掉重复多余的元件,力求系统结构简单。
本文对剪叉式平台的液压系统与回路进行了简单的分析与阐述,并对课题要求的设计要求进行了方案设计与分析,通过进一步的验算选定了所需要的液压元件。通过运用AutoCAD绘制液压系统原理图、液压平台装配图、液压缸及其他零件图。最后通过验算证明了本设计的准确性。

Abstract
With the development of logistics and automobile industry, the equipment industry that serves it has become a new industry in our country. Sales increased year by year. This design hydraulic lifting platform with shear-fork structure.
In recent years, the literature on hydraulic system of shear-fork platform is not uncommon, but the content of literature is mostly focused on a topic, but there are few papers on hydraulic system of modern shear-fork platform. Therefore, the research and design of shear-fork platform hydraulic system has important practical and theoretical significance.
This paper mainly summarizes the development history of hydraulic technology of shear-fork platform and its development situation at home and abroad, and briefly describes the development trend of shear-fork platform. The hydraulic system diagram of the whole machine is composed of control circuits and hydraulic sources drawn up separately. When the circuits are combined with each other, duplicate redundant elements are removed, and the system structure is simple.
In this paper, the common hydraulic circuit of the shear-fork platform is simply described and analyzed, and the hydraulic system of the shear-fork platform is designed and analyzed. The hydraulic system schematic diagram, the working tank assembly, the hydraulic layout drawing, the oil tank parts drawing are drawn by using AutoCAD. Finally, the feasibility of the design is proved by checking calculation.
