摘要防火板集料装置用于生产流水线末端半成品的归集，以便于成批输送至干燥车间。与叉车等车辆配套适用，可实现货物的快速装卸等。这样能大幅度的提高生产效率，减少工人的劳动力。其中升降机采用全液压系统控制，能产生更多的动力，而且液压装置的体积小，重量轻，功率密度大，结构紧凑。易于实现快速启动，制动等控制。

通过对剪叉式升降台机构技术特点分析，结合具体工作状况，规划出升降台各部分零件以及液压缸布置方式，并根据要求对液压传动系统各部分进行设计计算最终确定液压执行元件-液压缸的相关参数，通过对升降杆的各工况受力分析确定升降杆的结构，最终完成剪叉式液压升降台的设计。49739

在机器设计过程中，首先利用Solidworks软件对规划的机件三维建模并虚拟装配，然后根据力学分析确定准确结构尺寸并修改三维模型。通过运动仿真动画，动态观察结构之间的干涉状况及位置参数等。三维模型完善之后，设计最终的二维工程图。

 Abstract 

Fire board material collection device for production line end semi-finished products separately, in order to delivery to the drying plant. Forklift trucks and other vehicles and supporting applied, can realize the rapid loading and unloading of cargo. This can greatly improve production efficiency, reduce the labor of workers. The lift adopts full hydraulic control system, can produce more power, and the hydraulic device has the advantages of small volume, light weight, large power density, compact structure. Easy to achieve quick start, brake control.

The shearing fork type lifting platform mechanism analysis of technical characteristics, combined with the specific situation of planning and design work, a lifting table of each part and a hydraulic cylinder arrangement, and according to the requirements of the hydraulic system on the part of the design and calculation of hydraulic actuator - ultimately determine the hydraulic cylinder of the relevant parameters, based on the lifting rod of various conditions of a subject stress analysis to determine the lifting rod structure, finally complete scissor type hydraulic pressure lifting platform design.

During machine design, the first use of Solidworks software on the planning of the mechanical3D modeling and virtual assembly, and then according to the mechanics analysis to determine the exact structure size and modify3D models. Through the motion simulation animation, dynamic observation of structure between the interference condition and position parameters. 3D model after perfecting, final design of two-dimensional engineering drawings.
