摘　　要：为实现中国通商口岸木材的自动化搬运,本文设计一款专用于木材转运的机械设备。采用Creo5.0中的Parametric模块对木材转运设备的各个机构和零件进行三维建模,主要包括龙门架主体框架结构、夹持机构和运载火车底盘(轨距为1435 mm和1520 mm)。根据运动方式的不同,采用不同的连接方式对各个机构进行装配,在夹持机构夹片末端内侧添加一个观测点,并对装配模型进行运动仿真分析。仿真结果表明,木材转运设备的各个机构能够协调工作,解决了各个零件之间的装配方式与运动合理性问题;对木材转运设备的三维模型进行优化,以提高木材转运的效率,使设计方案更加完善,为木材转运设备的后续研究与优化奠定基础。In order to realize the automatic transportation of wood at China’s trade ports,this paper designs a special mechanical equipment for timber transfer.The parametric module of Creo5.0 is used to model the various mechanisms and parts of the timber transfer equipment,including the main frame structure of the gantry frame,clamping mechanism and the chassis of the carrier train(the gauge is 1435 mm and 1520 mm).According to the different motion modes,different connection modes are used to assemble each mechanism.An observation point is added to the inner side of the clamp end of the clamping mechanism,and the dynamic simulation analysis of the assembly model is carried out.The simulation results show that the various mechanisms of the designed timber transfer equipment can coordinate work,and solve the problems of assembly mode and motion rationality between the various parts;optimize the three-dimensional model of the timber transfer equipment,in order to improve the efficiency of timber transfer,make the design scheme more perfect,and lay a foundation for the follow-up research and optimization of timber transfer equipment.
