摘要
近几年来,随着物流行业的迅猛发展,港口产业也日益壮大。门座式起重机作为一种高效率的起重运输机械在港口被广泛使用。回转机构是门座起重机的主要工作机构之一。回转机构对于起重机的整体性能有决定性的影响。因此,对门座起重机回转机构的研发设计做进一步探讨有非常重要的现实意义。
本文设计以MQ4040单臂架门座起重机为研究对象,使用SolidWorks及Adams软件对其进行总体设计以及回转机构设计。主要工作如下:
(1)在MQ4040门座起重机的总体设计中,首先对起重机进行了大体设计。随后对货物水平位移补偿系统和臂架自重平衡系统进行设计及校核。最后,对起重机设计的相关载荷进行计算,并对轮压、抗倾覆稳定性校核和抗风防滑安全性进行验算。
(2)在回转机构设计中,首先对回转机构布置进行选择,随后进行回转支承装置及回转驱动的设计计算。最后使用Atuocad软件进行相关工程图纸的绘制。
(3)在三维建模中,使用SolidWorks软件对回转机构各个零件进行三维建模。然后将所有零件模型进行装配,组成回转机构。经过分析,模型无干涉,可进行下一步的Adams运动学仿真。

Abstract
In recent years, with the rapid development of the logistics industry, the port industry has also grown. Portal cranes are widely used in ports as a highly efficient lifting and transporting machine. The slewing mechanism is one of the main working mechanisms of the portal crane. Slewing mechanism has a decisive influence on the overall performance of the crane. Therefore, it is of great practical significance to further explore the design of the portal crane slewing mechanism.
This article designed the MQ4040 single-arm portal crane as the research object, using SolidWorks and Adams software for its overall design and rotary mechanism design. The main work is as follows:
(1) In the overall design of the MQ4040 portal crane, the general design of the crane was first performed. Subsequently, the horizontal displacement compensation system and the boom self-balancing system were designed and checked. Finally, the relevant load of the crane design is calculated, and the wheel pressure, anti-overturning stability check, and anti-skid safety are checked. [资料来源:https://www.doc163.com]
(2) In the design of the slewing mechanism, the slewing mechanism arrangement is first selected, and then the slewing bearing device and the slewing drive are calculated and calculated. Finally use Atuocad software to draw related engineering drawings.
(3) In the three-dimensional modeling, SolidWorks software is used to perform three-dimensional modeling of various parts of the slewing mechanism. Then all the part models are assembled to form a slewing mechanism. After analysis, the model has no interference and can perform the next Adams kinematics simulation.
(4) In the Adams kinematics simulation, the built 3D model was imported into Adams software, and dynamic simulation was completed by adding appropriate constraints and drivers to the parts. Finally, the simulation results are output. After analysis, the simulation results meet the design requirements.
