【摘要】：随着我国现代化进程的发展，煤炭资源的需求量不断加大，对立井提升系统的安全、高效生产提出了更高的要求。调绳作业是立井提升系统维护必须进行的一项重要工作。调绳作业的安全、快速进行是依靠可靠的调绳装置及调绳工艺来保证的。现有的调绳装置功能单一、只能调节安装侧钢丝绳、松绳困难、不能实现对提升系统的安全保护，已经无法满足使用需求。本课题通过对现有国内外调绳装置的对比分析，针对其不足，充分考虑现场实际使用需求，提出了多功能调绳装置的总体方案，使其能够实现调绳功能、安全保护功能和卡绳功能。本文设计了该装置的机械、液压、电控部分，介绍了各部分的组成以及各功能的实现。通过分析多功能调绳装置的各工况和现有的楔形锁绳装置，本文设计了新的齿轮齿条式锁绳部件，并对其抓捕动态钢丝绳及夹紧静态钢丝绳进行了力学分析，指出安全保护抓捕时钢丝绳受到的摩擦力应小于钢丝绳最小破断拉力以及锁绳部件的自锁条件。应用ADAMS软件对齿轮齿条式锁绳部件的锁绳过程进行了动力学仿真，仿真结果表明齿轮齿条式锁绳部件能够在不同工况时安全可靠的锁紧钢丝绳，为多功能调绳装置各功能的实现提供了基础。安全保护功能的抓捕响应时间与抓捕同步性是安全保护抓捕的关键参数。使用蓄能器作为安全保护抓捕时的动力源，在AMESim软件中仿真研究蓄能器对抓捕响应时间的影响。在AMESim软件中仿真研究液压同步分流马达对抓捕同步性的影响，仿真结果表明使用液压同步分流马达后，，安全保护抓捕的抓捕同步性误差不超过3%，能够满足实际使用需求。多功能调绳装置工作时载荷最终都会传递到承载部件上，多功能调绳装置的承载部件主要由移动锁绳器和下锁绳器的主板、移动锁绳器的移动承载组件以及承载底座组成。本文分析了主板、移动承载组件和短承载梁的受力情况，做出初步结构设计。应用Solidworks软件对主板、移动承载组件和短承载梁进行了三维实体参数化建模，并利用ANSYS Workbench软件对其进行了静力学分析和结构优化设计，得到较为合理的结构，为其设计提供了理论依据。
[Abstract]:With the development of China's modernization process, the demand for coal resources is increasing, and the safety and efficient production of the antithetical well hoisting system has put forward higher requirements. Rope adjustment is an important task in the maintenance of shaft hoisting system. The safety and speed of rope adjusting operation are guaranteed by reliable rope adjusting device and rope adjusting technology. The existing rope adjusting device has a single function and can only adjust the installation side of the wire rope. It is difficult to loose the rope and can not realize the safety protection of the lifting system and can no longer meet the needs of use. Based on the comparative analysis of the existing domestic and foreign rope regulating devices and considering their shortcomings, the overall scheme of the multi-function rope adjusting device is put forward in order to realize the rope adjusting function. Safety protection function and rope clamp function. In this paper, the mechanical, hydraulic and electronic control parts of the device are designed, and the composition of each part and the realization of each function are introduced. Based on the analysis of the various working conditions of the multi-function rope adjusting device and the existing wedge-shaped locking rope device, a new gear and rack type locking rope component is designed, and the mechanical analysis of its capture of dynamic wire rope and clamping static wire rope is carried out. It is pointed out that the friction force of wire rope should be less than the minimum breaking force of wire rope and the self-locking condition of lock rope. The dynamic simulation of the lock rope process of the gear rack type lock rope component is carried out by using ADAMS software. The simulation results show that the gear rack type lock rope component can secure and reliable lock steel wire rope under different working conditions. It provides the foundation for the realization of the various functions of the multifunctional rope adjusting device. The capture response time and synchronization of security protection function are the key parameters of security protection arrest. The accumulator is used as the power source of safety protection and capture. The effect of accumulator on the capture response time is simulated in AMESim software. The effect of hydraulic synchronous shunt motor on catching synchronicity is studied by simulation in AMESim software. The simulation results show that after using hydraulic synchronous shunt motor, the catch synchronicity error of safety protection arrest is less than 3 parts, which can meet the need of practical use. The load of the multi-function rope adjusting device will be transferred to the bearing part when it works. The bearing part of the multi-function rope adjusting device is mainly composed of the main board of the moving-rope locking device and the lower locking device, the moving load-carrying component of the moving-rope latching device and the bearing base of the moving-rope latching device. In this paper, the stress of main plate, moving bearing component and short bearing beam is analyzed, and the preliminary structural design is made. The 3D solid parametric modeling of the main board, moving load-bearing component and short load-bearing beam is carried out by using Solidworks software, and the statics analysis and structural optimization design are carried out by using ANSYS Workbench software, and a more reasonable structure is obtained. It provides a theoretical basis for its design.
