摘　　要：带式输送机作为煤矿井下主煤流运输装备,目前正朝着重型化和智能化的方向发展。传统异步驱动系统和液压张紧装置存在电动机工作效率低、能耗高、维护困难、液压缸易泄漏和张紧滞后等问题,难以满足矿用重型带式输送机高效、智能、可靠的驱动技术要求。以内蒙古某矿 3 km 长顺槽带式输送机为例,开展了驱动系统和张紧装置的永磁改造设计及应用研究。在尽量不改变输送机原有结构及参数的基础上,设计了包含 3 台永磁同步电动机及其变频驱动器、1 套永磁电张紧装置、1 台综合控制器的永磁直驱与永磁张紧一体化系统,并在煤矿井下完成了设备安装及应用。结果表明,经永磁改造后的带式输送机可解决原输送系统存在的种种问题,具有良好的动态响应特性,提高了煤炭的开采量,增加了煤矿的经济效益。As the main coal flow transportation equipment in the underground colliery,the belt conveyor is developing towards heavy-duty and intelligence.The traditional asynchronous drive system and the hydraulic tensioning device possess many issues such as low efficiency,high energy consumption,difficult maintenance of the motor,easy leakage of hydraulic cylinder and tensioning lag,which make it difficult to satisfy the technical requirements of efficient,intelligent and reliable drive.Taking 3 km long trough belt conveyor in a mine in Inner Mongolia as the example,the paper carried out the permanent magnet modification design and application research of the drive system and the tensioning device.On the premise of not changing the original structure and parameters of the conveyor as far as possible,it designed a permanent magnet direct drive and permanent magnet tensioning integrated system involving three permanent magnet synchronous motors with variable frequency drivers,one set of permanent magnet electric tensioning device and one integrated controller.And the equipment installation and practical application were completed in underground colliery.The results showed that the belt conveyor after permanent magnet modification not only solved various issues existing in the original conveyor system with excellent dynamic response characteristics,but also improved the coal production and increased the economic benefit of the colliery.
