为解决煤矿井下传统绞车牵引设备列车采用钢丝绳牵引、频繁带电移动牵引绞车、高空悬挂单轨吊以及铺设轨道带来的安全风险问题,避免设备列车在运输过程中发生自滑移、掉道、翻车、跑车、钢丝绳断裂等事故,研制KDYZ40-40/2000矿用电控液压移动列车组,对综采工作面动力控制设备提供安全保障,介绍了传统绞车牵引设备列车的工作原理,分析了长距离遥控式设备列车组整体结构形式,采用设备列车整体同步升降、迈步推移调偏体系,锚固牵引装置、自移平板车以及自动伸缩管缆装置解决了设备列车随工作面推进同步移动、调偏与管揽自动伸缩等问题,分析了设备列车采用的分组遥控电液控制系统,环形供液以及多传感器反馈闭环控制方式,提高了列车长距离控制速度,实现了列车同步平稳安全运行。结果表明:该设备列车组能够适应巷道高度2.0 m以上的工况条件,取消绞车牵引、高空悬挂单轨吊以及铺设轨道,简化了劳动组织工序,提高设备整体运行安全性以及速度,有效保证安全高效生产,推进综采面自动化、无人化管理。
In order to solve safety hazardscaused by the use of steel wire rope traction,frequent live-moving traction winches,high-alti⁃tude suspension monorail cranes,track laying of traditional winches in coal mines,and avoid accidents such as self-skidding,falling lanes,overturning,out of rails,wire rope breaks of equipment trains during transportation,the KDYZ40-40/2000 mine-used electroni⁃cally controlled hydraulic mobile train set was developed to provide safety guarantee for the power control equipment of fully-mechanized mining face.The working principle of traditional winch traction equipment train was introduced,and the overall structure of long-distance remote-controlled equipment train set was analyzed.It solved problems of synchronous movement of equipment train with the working sur⁃face,deviation adjustment and automatic expansion and contraction of pipe by using equipment train’s overall synchronous lifting,stepand-shifting deviation adjustment system,anchoring traction device,self-moving flat vehicle and automatic telescopic tube cable device.The grouped remote electro-hydraulic control system adopted by equipment train,loop liquid supply and multi-sensor feedback closedloop control method were analyzed,which improved long-distance control speed of train and realized synchronous and safe operation of train.The results show that use of remote control equipment train set can adapt to the working conditions of tunnel height above 2.0 m,e⁃liminating winch traction,high-altitude suspension monorail hoisting and laying track,simplifying labor organization process,improving the overall operating safety and speed of equipment,and effectively ensuring safety and efficiency and promoting automation and unmanned management of fully-mechanized mining face,thus fundamentally revolutionize the working methods of equipment trains.
