| 7. | No job is too tough for this digger ! with its big working treads , rotating cabin , moving arm and tilting shovel , it can reach every corner of the construction site 对这个挖土机来说没什么工作是困难的!用它的大轮子,旋转的工作间,动臂和摆式铁铲,它可以到达施工现场的每个角落。 |
| 8. | It can replace the big tower crare and other lifting machine in special construction sites where the working condition si very tough . this kind of hoist features high efficiency and economic operation 在施工条件较困难的情况下,可取代传统施工配置的大型动臂式塔机,或其他卷扬机构。工作效率较高,十分经济。 |
| 9. | Users needn ’ t establish the model themselves . through the verification of practical engineering projects , the program afforded by this article is simple and easy to use , as well as accurate and reliable 运用本文开发的格构式动臂港口轮胎起重机结构参数化计算分析平台对qly50港口轮胎式起重机进行参数化建模分析,验证了本参数化设计分析平台的有效性和实用性。 |
| 10. | According to the principle of curve axial symmetry , authors inferred the theoretical foundation of error - free translation of the working equipment of loader and proved that when the diameter of piston rod on arm oil cylinder was designed properly , the two oil cylinders could be guaranteed to have a synchronous movement which made the bucket maintain translation throughout the working process under the condition of the oil cylinder ' s basic parameter ; also made the equipment structure of the loader greatly simplified and provided the reference for improvement of the present equipment of loader 根据曲线轴对称原理,推导出了能使装载机工作装置无误差平移的理论基础,证明了只要适当地设计动臂油缸活塞杆直径,就可以在油缸的基本参数上保证机构工作时两油缸同步运动,使铲斗在作业过程中保持平移;使装载机工作装置结构大为简化,为进一步改进现有装载机工作装置提供参考。 |
