【摘要】：水利工程启闭设备是一种专门用来启闭水工建筑物中的闸门用的起重机械，是水利工程建设中重要的永久设备，其质量好坏、运行可靠性直接影响到水利工程防洪排涝、调水供水、灌溉、发电、航运等综合效益的发挥、水利工程运行安全及人民生命财产的安全。目前我国启闭设备仍主要依靠经验或简单的单项试验来评价。随着我国水利行业的不断发展，建立、健全启闭设备的试验方法和实验手段成为当前迫切需要解决的问题。本文完成了水利工程启闭设备综合试验平台的设计，考虑到试验评价要求的发展，实验平台还具备了一定前瞻性和扩展性。主要研究内容如下：（1）从水利工程启闭设备本身的结构特点、运行特点出发，根据启闭设备种类繁多、型式多样的特点，完成了水利工程启闭设备综合试验平台的方案设计，及各种不同型式启闭设备试验评价的操作方案，，满足了国家标准中关于各类型启闭设备的具体试验要求。（2）完成了综合试验平台的结构设计。重点针对平台的主承载构件——主体钢结构平台，以ANSYS有限元分析软件为平台，分析计算了各种试验工况下钢结构平台的强度和刚度，并根据仿真计算结果，提出了结构改进和优化措施。满足了启闭设备综合试验平台运行安全性和稳定性要求。（3）完成了综合实验平台的地下混凝土基础、地上钢结构平台及配套工装、被实验设备电气控制系统、信号采集系统、配重及附属设施的设计。水利工程启闭设备综合试验平台的设计，丰富了水工设施试验评价方法和手段，为保障水利工程正常运行起到了一定的保障作用。
[Abstract]:The hoisting equipment of hydraulic engineering is a kind of lifting machinery specially used to open and close the gate in hydraulic structures. It is an important permanent equipment in the construction of water conservancy projects. Its quality and operation reliability directly affect flood control and drainage of water conservancy projects. Water diversion, irrigation, power generation, shipping and other comprehensive benefits, water conservancy project operation safety and people's life and property safety. At present, our country hoist still mainly depends on experience or simple individual test to evaluate. With the continuous development of water conservancy industry in China, it is urgent to solve the problem of establishing and perfecting the test methods and experimental means of the hoist and switchgear. This paper has completed the design of the comprehensive test platform for the opening and closing equipment of water conservancy projects. Considering the development of the test evaluation requirements, the experimental platform also has some foresight and expansibility. The main research contents are as follows: (1) based on the structural characteristics and operation characteristics of the opening and closing equipment of water conservancy projects, according to the characteristics of various types and types of the opening and closing equipment, The scheme design of the comprehensive test platform for the opening and closing equipment of water conservancy engineering and the operation scheme for the test evaluation of various types of hoisting and closing equipment have been completed, which meet the specific test requirements of each type of opening and closing equipment in the national standard. (2) the structural design of the comprehensive test platform is completed. Aiming at the main bearing member of the platform, the main steel structure platform, using ANSYS finite element analysis software as the platform, the strength and stiffness of the steel structure platform under various test conditions are analyzed and calculated. The measures of structure improvement and optimization are put forward. It meets the requirements of safety and stability of the integrated test platform for the hoist. (3) the underground concrete foundation of the comprehensive experimental platform, the above ground steel structure platform and its supporting tooling, the electrical control system, the signal acquisition system, the counterweight and the auxiliary facilities of the experimental equipment are designed. The design of comprehensive test platform for water conservancy equipment enriches the evaluation methods and means of hydraulic facilities test and plays a certain role in ensuring the normal operation of water conservancy projects.
