【摘要】 夹钳装置归属于起重机械的取物装置一类。取物装置是将起吊物品与起升机构联系起来,并使起重机进行正常作业的一个重要部件。现有的取物装置大致分为通用取物装置(吊钩吊环等)和专用取物装置(夹钳集装箱吊具等)。给通用起重机配置上各种专用取物装置,就可以代替各种专用起重机实现多种工作要求。这是起重机发展的一种趋势。本文力图建立夹钳取物装置机构设计的一般方法,为以后的设计者提供有价值的理论基础和实用设计资料。本文以夹取机构的设计为主线,讨论夹取机构设计中的一系列问题。首先,基于基元式机构创新设计方法建立夹取机构方案,探讨了夹取机构的基本单元,在此基础上进行了机构拓扑,最后得出了多种夹取机构运动方案。其次对夹钳机构的构件尺寸进行了计算,在计算过程中对重要参数进行了研究,通过建立的夹钳机构的力学模型,对典型夹取机构进行了运动学分析,最后运用PRO/E对20T机械杠杆式夹钳进行了建模,并进行了相关零部件设计,利用ADAMS软件对主要零部件进行动力学仿真。其研究成果已用于样机研制,取得了预期效果。本文较全面的研究了夹取机构设计的关键技术,通过引入基元式机构创新设计方法,建立了夹取机构的基本单元,进行了方案设计与机构综合,建立了夹钳机构的力学模型,为夹取机构设计提供了一种有效的实用的方法。更多还原

【Abstract】 Clamp is ascribed to extract devices of lifting equipment. Extract device is important component, linking work-piece to hoisting mechanism. Extract device is divided into two kinds. One is dedicated (spreader hoisting mechanism etc.), The other is current general (crane hook、lifting bolt etc.). Allocating dedicated clamp device to general lifting equipment could implement many special functions. It is development tendency of lifting equipment. This article tries to establish general method to design clamp device, to provide valuable theory and information on engineering for designer.This article discuss series design project of clamp around the design of clamp mechanism. Firstly, establish kinematics precept design on base of the elementary method of mechanism creation design. Discuss basic cell of clamp mechanism. Topology 2-10 bar clamp mechanism by basic cell. The second, Introduce the process of dimension calculation of clamp mechanism. Discuss the key parameter on the process of dimension calculation. Establish mechanical model of clamp mechanism for kinematics analysis. Lastly, Apply PRO/E to create 3D model of the pars of 20T mechanical clamp device. Discuss ADAMS-based the process of kinetics simulation of 20T mechanical clamp device.The value of this article is establishing the general method of clamp device all-round, discussing the core part of clamp design process. On kinematics precept design, introduce the elementary method of mechanism creation design. Find the basic cell of clamp. Discuss the process of synthesis of mechanism of clamp device. Provide the experience to clamp designer. For kinematics analysis, creat the basic mechanical model of clamp mechanism. Solve the kinematics project to apply traditional analytical method.更多还原
