大型H钢翻转提高机构设计
摘 要本文一方面对翻转机提高类型从其特点进行分析到选取，选取出链式翻转机构和液压式提高装置，对H钢翻转工作进行分析，设计出符合规定元器件如轴，齿轮，皮带等，对某些件进行校核，为了元件互相协调配合，设备运营平稳。最后设计出液压与电气系统组合，从而形成一套完整工作体系从上升正反翻转、制动、下降。
提高机构选取形式为液压式，长处是重量轻、容易实现调速、使用寿命长。缺陷是油液对密封装置规定比较严苛容易泄露。翻转机构使用链式传动，长处是摩擦性好、成本低。缺陷不耐冲击、质量大。
核心词 H钢；翻转机构；提高机构
Design of Large Scale H Steel Lifting Mechanism
Abstract
China is now the level of industrial development，H steel used more and more widely in the field，lifting and turning of the heavy and large parts can not only rely on manpower to complete，in order to improve the production efficiency we need to design a device to solve this problem. At the same time the design should take into account the loose gear and lubrication problems.
Based on the analysis of the types of hoisting machine turn to choose from its features，choose a chain turnover mechanism and a hydraulic lifting device for H steel turning work analysis，designed to meet the requirements of the components such as shaft，gear，belt and so on，to check the part，as the components of coordination，equipment running smoothly. Finally，the hydraulic and electrical system is combined to form a complete system of work，from rising，reverse，braking and descending.
The selection of lifting mechanism is hydraulic，with the advantages of light weight，easy realization of speed control and long service life. The disadvantage is that the oil on the sealing device requirements are more stringent，easy to leak. The turnover mechanism adopts chain type transmission，and has the advantages of good friction and low cost. Disadvantages，no impact，high quality.
Keywords H steel，turnover mechanism，lifting mechanism
