新疆乌准铁路实现双机重联5000吨列车规模化开行

2017-09-15 23:11:42   央广网

今年以来,随着乌准铁路运量的骤增,硬件设施不足、运能紧张的“短板”制约了货运上量的脚步。新疆铁路部门将“多拉快跑”作为提升运能的“砝码”,推进机务运用组织改革,全面提升机车运用效率。

“以往,乌准铁路采用DF8B型内燃机车单机牵引货物列车,机车牵引功率最高为3100吨。由于线路运用紧张,存在装好的列车等线路的情况。”乌鲁木齐机务段技术科副科长吕建光介绍。

新疆铁路部门将提高机车牵引能力、开行双机重联5000吨列车作为释放线路运能的突破口,从机车设备改造、优化乘务组织、提高列车运行速度三个方面持续实施技术革新,推动运输组织模式的创新,将单列货物列车的载重能力由3、4000吨提高到5000吨。

自今年5月1日起,新疆铁路部门投入资金,组织人员对东风8B型内燃机车进行双机重联改造技术攻关,通过3个多月的反复试验,完成了机车制动管路、电器线路、微机设备等关键设备的重联技术改造。经过改造的机车实行双机重联后,可实现由一名机车乘务员操纵两台机车,做到功率匹配、精细操纵,在经过乌准铁路两个长大坡道时减少了摘挂机车的过程,运行时间有效缩短,满足了乌准线开行双机重联5000吨列车的需求,实现运能充分释放。

随着50台双机重联机车成批投入乌准铁路使用,新疆铁路部门进一步优化人员配置。一方面,通过内部挖潜将人力资源向乌准铁路倾斜,配齐配足人力机班,机车乘务员由当初的40余人增加到200人。另一方面,进一步优化机车乘务组织,实施“2+1”值乘模式(即:2台DF8B双机重联牵引,一位机车一名机车乘务员、一名机车副司机;二位机车一名副司机),与过去相比,每列车可节省一名机车乘务员。

推进乌准铁路运输组织模式的创新,新疆铁路部门积极开展货物列车提速攻关,通过现场调研,修订完善技术标准,精心设计提速试验方案,经过多次提速试验,于8月18日将货物列车运行速度由每小时80公里提高至每小时90公里,输送能力提升5列以上。同时,新疆铁路部门进一步细化机车操纵及检修作业标准,分批对机车乘务员及检修人员进行双机重联操纵技能及检修整备作业标准的针对性培训,促进机车乘务员岗位技能和应急处理能力的提高。

“开行双机重联5000吨列车后,不但增加了煤炭运量,还满足企业铝粉、铝锭、PVC化工产品等大宗原料采购、产品销售需求,实现了往返均衡运输。”乌鲁木齐铁路局货运处负责人表示。

近期,随着双机重联5000吨大列的开行,乌准铁路运能紧张的状况得到明显缓解。准东北站天环线、神环线通过实施设备改造、优化装车流程,压缩列车在环线内的运行时间,单列装车时间由过去的3个多小时压缩到2小时40分左右。近期,天环线煤炭装车启用了双漏仓装车模式,单日装车达10列,创下历史新高。目前,天环线、神环线每天的装车能力分别达10列、9列。

如今,隆隆铁龙唤醒戈壁,煤炭、铝粉、化工等大宗产品大进大出,带动天山北坡经济带煤炭、煤电、现代煤化工、煤电冶、新能源、新材料产业发展。

随着乌准铁路提速扩能工程的持续推进和双机重联机车大批投入使用,运输能力将进一步提高,将为新疆铁路完成年度货发量9500万吨以上的目标提供助力。

目前,新疆铁路部门在兰新铁路、南疆铁路等区段已基本实现5000吨大列常态化开行,此次乌准铁路实现规模化开行双机重联5000吨列车后,将有效促进铁路运能的快速释放,推动新疆经济进入加速度发展的“快车道”。
