摘要: 为解决传统竖井施工中机械化程度低、人力消耗大,安全风险高等问题,研发了一种沉井潜入式竖井掘进机。该掘进机可以实现打井不下井,开挖、出渣、支护同步作业,自动、高效施工。本文针对沉井潜入式竖井掘进机的相关结构进行了如下研究:首先,系统阐述了沉井潜入式竖井掘进机的结构组成和工作原理。然后,基于受力特性和运动特性,分别对其工作装置进行力学特性分析、运动学特性分析,构建其运动学分析简易模型。其次,采用有限元法对关键部件进行静强度分析,得到其对应的应力云图和变形量云图,验证关键部件在强度和刚度方面符合设计要求。最后,基于虚拟样机技术对其关键部件以及关键位置处进行运动学研究和动力学研究,得到其位移和受力曲线图。结果表明:该竖井掘进机结构设计、力学特性分析以及运动学分析合理,有限元法和虚拟样机技术运用可行。研究结果为后续竖井掘进机的优化设计奠定了一定的理论基础。研制出沉井潜入式竖井掘进机样机,进行了厂内工业试验,为工程应用打下基础。

Abstract:

In order to solve the problems of low degree of mechanization, high manpower consumption and high safety risk in traditional shaft construction, a caisson submerged shaft boring machine is developed. The boring machine can realize the simultaneous operation for excavation, slag discharge and support, and automatic and efficient construction. The related structural research is as follows. First,

the structure and working principle of the shaft boring machine is systematically explained. Second, based on the force characteristics and kinematic characteristics of the working device, the mechanical characteristics and kinematic characteristics of the working device are analyzed, and a simple model of its kinematics analysis is constructed. Thirdly, the static strength of the key components is analyzed by adopting the finite element method, the corresponding nephogram of stress and deformation are obtained, which can verifiy that the strength and stiffness of key components meet the the design requirements. Last, based on virtual prototype technology, the research of kinematics and dynamics on its key components and key positions is carried out, obtaining its displacement and force curve diagrams. The results show that: the structural design, the mechanical property and the kinematics analysis are reasonable; the techonogies of finite element method and the virtual prototype are feasible. The results provide a reference for optimal design of shaft boring machine. On the basis, a prototype of the caisson submerged shaft boring machine is developed and in-plant industrial test is carried out, which lays a foundation for engineering application.
