带机械手的起重机结构设计(含CAD图)(设计说明书15000字,CAD图7张)
摘要：本文以带机械手的起重机为研究对象，系统阐述其结构设计方法与理论依据。通过整合起重机性能分析、机械手功能集成及《机械设计手册》规范要求，完成起升机构、运行机构及主梁的优化设计。基于三维建模与有限元分析，提出双联滑轮组件的创新应用：采用双联动滑轮结构，显著降低吊钩水平偏移量，提升起吊稳定性；同时优化卷筒与钢丝绳匹配参数，简化安装流程并延长钢丝绳寿命。整机集成桥架、大，小车运行机构、柔性机械手及集中控制系统，实现工作效率提升，设计周期缩短，为自动化搬运场景提供了高精度、低振动的解决方案。
在整体系统的设计上沿用了传统思路，采用最常见的机构来制定设计方案，并完成了设备的大体布局，整机控制采用了集中控制。动滑轮组件采用了双联滑轮组件，保证了起吊过程中吊钩水平运动较小，从而使得整个起吊的过程能保持平稳状态，同时，采用该结构，钢丝绳的安装和更换也相对比较简单。钢丝绳将被安置在与其适配的卷绕装置（卷筒）里，其具有与钢丝绳接触面积大和钢丝绳单位面积压力小的特点。起升机构还包括有：绳索、减速器、联轴器、电机和制动器等。对于大车驱动机构和小车传动机构、提升机构，还应参与相关例如车轮压力、减速器、联轴器、电机和制动器等的计算。 [资料来源：https://www.doc163.com]

Structural Design of Crane with Mechanical Arm
This article focuses on the design process and general design theory of cranes with mechanical arms, including the various performance, structure, and development status of cranes, as well as the introduction of mechanical arms. Based on the "Mechanical Design Manual", the design of the lifting mechanism and related components of the crane is designed and improved. From the initial scheme formulation, to the verification calculation of the main beam, to the design of the 3D model on the computer, the specific design details are finally finalized to improve the efficiency of the crane, increase the design speed and quality tasks, and shorten the design cycle.
The crane with a robotic arm in this article consists of a bridge frame, a small car operating mechanism, a large car operating mechanism, a lifting mechanism, a flexible robotic arm, and electrical equipment. In the overall system design, we followed the traditional approach and used the most common mechanisms to develop the design plan, and completed the overall layout of theequipment. The whole machine control adopted centralized control. The movable pulleycomponent in this design adopts a double pulley component, which ensures that the horizontal movement of the hook is small during the lifting process, thereby maintaining a stable state throughout the lifting process. At the same time, with this structure, the installation and replacement of the steel wire rope are relatively simple.

The steel wire rope will be placed in a winding device (drum) that is compatible with it, which has the characteristics of a large contact area with the steel wire rope and a small pressure per unit area of the steel wire rope. The lifting mechanism also includes ropes, reducers, couplings, motors, and brakes. For the large vehicle drive mechanism, small vehicle transmission mechanism, and lifting mechanism, they should also participate in calculations related to wheel pressure, reducers, couplings, motors, and brakes
