Abstract

At present, the air conditioning unit assembly line of railway bus electrical integrated control cabinet mainly depends on PLC operation and control. PLC is one of its core and key components. Bus air conditioning unit can dynamically detect current, resistance and so on, but also can be used in the unit failure. Take the corresponding protective measures immediately, the data on the display can reflect the problem, and provide the basis for the unit's targeted maintenance. Aiming at the protection of air conditioning unit of railway bus electrical integrated control cabinet, this paper mainly discusses its protection from the composition of air conditioning unit and the composition of electric integrated control cabinet based on PLC.

Aiming at the protection of air conditioning unit of railway bus electrical integrated control cabinet, this paper mainly discusses its protection from the composition of air conditioning unit and the composition of electric integrated control cabinet based on PLC. At present, PLC. is widely used in the electric integrated control cabinet of railway passenger cars under the control and instruction of the PLC, once there is a problem or failure in the operation of the bus electrical system and the air conditioning unit, it can be diagnosed and protected in time. For this reason, the following from the PLC based electrical integrated control cabinet and air conditioning unit composition, specifically discussed the maintenance line measures.

1、绪论

1.1意义

随着铁路改革的不断深入,客货车数量不断增加,技术含量更高的控制柜流水线投入使用。从而控制柜流水线的缺点逐渐暴露出来,具体体现在:1。修复过程中的设计缺陷。现有控制柜流水线都是在上代以前设计制造的,其设计依据完全基于当时轮对维修任务量和轮对型号。设备布置不合理。新增加的设备增加了本已拥挤的维修线的难度。大型加工设备的老化影响轮对加工质量。设备自动化程度低;数据填报、汇总、统计、上报均为手工操作,数据填报重复率高。随着计算机技术的出现,人类社会正朝着知识经济和互联网时代迈进。信息技术和网络技术首次应用于企业生产,将大大降低企业成本,增强企业竞争力。综合考虑以上因素,轮对检修线必须从工艺流程、加工设备、各工序数据采集和数据传输三个方面进行综合改造。在流水线维修过程中,我们力求将人员、设备、材料所需的空间进行最适当的配置和最有效的组合,以获得最大的经济效益。控制柜流水线系统业务流程合理,技术先进,能够满足相关技术要求标准;信息系统信息处理顺畅,数据统计、传输准确准确地传送到铁道部。均能满足铁道部有关文件和出口规定的要求,也可以创造了可观的经济效益。

1.2目的

铁路客车电气综合控制柜是铁路客车运输的重要设备。其技术水平是中国铁路设备现代化的重要标志,也是铁路能否加快的关键。作为车辆的重要部分,铁路客车电气综合控制柜承担着确保驾驶安全性,有助于运输的双重责任。根据运输需求,铁路货物车在国家铁路范围内运行,没有固定的所属部门或固定的维修场所。实施定期检查和附近的扣除。也就是说,无论卡车在哪里行驶,只要车辆达到了预定的检查周期,铁路客车电气综合控制柜流水线日常检查和维护也将在车辆检查的同时完成。更换和修理车轮套件,以及新的车轮套件的组装工作,将分散在配送车轮套件按照计划。近年来,为了确保铁路客车电气综合控制柜流水线运行可靠性,车辆工程师不断改进设计和制造水平,积极采用新技术和新材料,从根本上改善轮毂的性能,而另一方面,各种维修单元不断改进试验装置的技术内容和自动化,积极推进专业的集中维护和寿命管理。这样的话,铁路客车电气综合控制柜流水线整体品质会大幅提高,事故的可能性也会有效减少。但是,分析了近5起脱轨事故的原因,其中3起是铁路客车电气综合控制柜破损。这表明铁路客车电气综合控制柜故障仍然是脱轨事故的主要原因。为了学习教训,进一步分析事故的根本原因,从数据统计分析可以看出,铁路客车电气综合控制柜有些零部件容易损坏。铁路客车电气综合控制柜流水线寿命和故障不仅与材料有关,还与组装的品质密切相关。

2、铁路客车电气综合控制柜检修流水线

2.1流水线概况

铁路客车电气综合控制柜检修流水线标准工作流程如图1所示。流水线实施后,根据工艺流程,对工序进行细分,确定每道工序的作业时间,确定每道工序的工人人数。生产单位组织技术人员和有经验的工人根据工艺文件和图纸编制作业指导书,为操作人员提供简明和全面的工作程

2.2流水线平面布局

电气综合控制柜检修流水线平面布局及工位设置如图(2)所示:

2.3水线工位划分

电气综合控制柜流水线共有8个装配工位,用于部件安装和接线。同时,为了避免装配线因配件而中断,设置缓冲站,在出现异常情况后,将芯材短时间存放。两个外壳装配区用于将装配线的芯线组装到外壳中,以及机柜门上附件的安装和布线。预接线架存放已完成的配线,边防仓库用于存放零散材料,可节省班组操作人员收集材料的时间。以Ac380V电气综合控制柜为例,划分各站相应的操作内容,如表1所示:
