  • 摘要

    为满足薄煤层综采工作面无人化需求,针对现有采煤机电缆存在需要专人看护的问题,设计了采煤机电缆自动拖拽系统,系统额定功率15 kW,工作面最大长度400 m,适应采煤机最大速度30 m/min。重点介绍了采煤机电缆自动拖拽系统的整体设计、参数设计和适配设计,并详细阐述了基于动力学仿真分析的拖缆链传动系统设计、适用于复杂工作面的轨道浮动对中技术、基于速度与转矩的自适应控制技术、电缆快速拆装技术等4项关键技术,解决了系统设计、机械结构、控制策略、故障保护等难题,实现了电缆夹始终处于微张紧状态。在张家峁煤矿14301工作面进行了工程应用,实现了全工作面自适应常态化运行,跟机率达到94.7%。该系统结构合理、可靠性高、拆装维护方便,可在现有工作面进行改造,可推广性强,促进了薄煤层无人化开采技术的进步。

  • Abstract

    In order to meet the unmanned needs of thin coal seam fully mechanized mining faces and address the issue of requiring dedicated personnel to monitor the cables of existing coal mining machines, an automatic cable dragging system for coal mining machines has been designed, The system has a rated power of 15 kW, a maximum length of 400m for the working face, and is suitable for a maximum speed of 30 m/min, This article focuses on the overall design, parameter design, and adaptation design of the automatic cable dragging system for coal mining machines, It elaborates in detail on four key technologies: the design of the cable chain transmission system based on dynamic simulation analysis, the track floating alignment technology suitable for complex working faces, the self adaptive control technology based on speed and torque, and the fast cable disassembly and assembly technology. The system design, mechanical structure, control strategy, fault protection, and other difficulties have been solved, It solves the problems of system design, mechanical structure, control strategy, and fault protection, and achieves that the cable clamp is always in a slightly tensioned state, Engineering application was carried out in the 14301 working face of Zhangjiamao Coal Mine, achieving adaptive and normalized operation of the entire working face, with a follow-up rate of 94.7%, The system has a reasonable structure, high reliability, convenient disassembly and maintenance, and can be retrofitted on existing working faces, It has strong scalability and promotes the progress of unmanned mining technology in thin coal seams.
