【摘要】：采煤机供电电缆和外接高压水管分别是采煤机电控系统和喷雾除尘系统不可缺少的部件,工作时电缆和水管随着采煤机的牵引而受到折弯、挤压；由于它们结构的特殊性以及对煤矿安全生产的重要性,工作时需对供电电缆和外接高压水管需要进行特别保护。目前,工作面广泛采用拖缆装置来保护、拖拽供电电缆和外接高压水管。但是,从目前的使用状况中发现,拖缆装置仍然存在保护失效、电缆夹板偏移、不同类型电缆夹板无法转接等问题,对煤矿安全、高效生产要求造成影响。因此为了满足煤矿生产机械化、自动化、高效化快速开采的要求,对现有拖缆装置进行研究和改进的意义重大。通过查阅大量文献,首先对拖缆装置的国内外研究现状进行分析,详细对现有拖缆装置的结构、工作原理、安装和使用现状进行研究,并提出现有拖缆装置使用时的缺点。对电缆夹板的类型及不同类型电缆夹板的结构进行研究：将布置在电缆槽内的电缆夹板划分成多个区域,分析影响不同区域工况的主导因素；对O型电缆夹板进行工况分析,并运用ANSYS Workbench对电缆夹板进行有限元分析；对电缆夹板的折弯角进行理论研究与计算,作为对拖缆装置改进的理论依据。对采煤工作面的施工需求进行分析,提出新型拖缆装置设计方案；在伸缩臂的设计方面,运用MATLAB Simulink对伸缩臂的调节液压缸控制系统在不同输入信号下的响应进行了分析；在转动臂的设计方面,详细对转动臂的关键零部件进行有限元分析；在过载保护系统的设计方面,对安全销强度进行计算；在转接板的设计方面,对转接板的结构进行设计,并对转接板进行有限元分析。运用D-H方法建立拖缆装置的的连杆坐标系及数学模型,确定连杆参数,求出摇臂的齐次变换矩阵,建立摇臂的运动学方程,运用MATLAB计算运动学方程各个参数；通过MATLAB Robotics建立拖缆装置仿真模型,求解摇臂在工作时的运动轨迹和相对于刮板输送机之间的位置关系,并求出拖缆装置的各个关节的变量与时间的关系。
[Abstract]:Shearer power cable and external high pressure water pipe are indispensable components of shearer electric control system and spray dust removal system respectively. When working, the cable and water pipe are bent and extruded with the shearer traction. Because of the particularity of their structure and the importance of safe production in coal mines, special protection should be given to power supply cables and external high voltage water pipes. At present, the working face widely used towing device to protect, towing power supply cable and external high-voltage water pipe. However, it is found from the current situation that the cable towing device still has some problems, such as protection failure, cable splint offset, and different types of cable splint can not be transferred, which has an impact on the safety and efficient production requirements of coal mines. Therefore, in order to meet the requirements of mechanization, automation and high efficiency of coal mine production, it is of great significance to study and improve the existing cable towing devices. By consulting a large number of literatures, this paper first analyzes the domestic and foreign research status of cable towing device, studies in detail the structure, working principle, installation and application status of the existing cable towing device, and puts forward the shortcomings of the existing cable towing device when it is used. The types of cable splints and the structure of different types of cable splints are studied. The operating condition of O type cable splint is analyzed, and the finite element analysis of cable splint is carried out by using ANSYS Workbench, and the bending angle of cable splint is theoretically studied and calculated as the theoretical basis for the improvement of cable towing device. Based on the analysis of the construction requirements of coal mining face, the design scheme of a new type of towing cable device is put forward, and the response of the adjusting hydraulic cylinder control system of the telescopic arm under different input signals is analyzed by using MATLAB Simulink in the design of the telescopic arm. In the design of the rotating arm, the key parts of the rotating arm are analyzed by finite element method in detail, and the strength of the safety pin is calculated in the design of the overload protection system. In the design of the plate, the structure of the plate is designed, and the finite element analysis of the plate is carried out. The D-H method is used to establish the coordinate system and mathematical model of the connecting rod of the towing cable device. The parameters of the connecting rod are determined, the homogeneous transformation matrix of the rocker arm is obtained, the kinematics equation of the rocker arm is established, and the parameters of the kinematics equation are calculated by using MATLAB. The simulation model of cable towing device is established by MATLAB Robotics to solve the movement track of rocker arm and the position relation between rocker arm and scraper conveyor, and the relationship between the variables of each joint and time of cable towing device is obtained.
