Description

轨道车辆模块化燃油输送装置 技术领域
本实用新型涉及轨道车辆模块化燃油输送装置。
背景技术
目前，发电车、轨检车及特种车(车上机组)燃油附属设备包括下油箱、上油箱、电动油泵、手摇泵、燃油过滤器、接油盘及各设备连接油管路组成。燃油附属设备安装方式为钢结构预埋螺栓，后期由车间作业人员组装各燃油设备，并连接相关管路。现有设计方案存在以下不足：
(1)钢结构预埋螺栓定位尺寸存在工艺误差，电动油泵、手摇泵及过滤器安装到位后，原先设计的管路经常需要原件改制，甚至报废；
(2)由于管路数量多，且管路加工厂家未按照图纸将管路一一编号。管路送至车辆组装车间后，操作工人往往需要花费3～4小时，通过图纸中的管路尺寸，对所需管路进行分类、辨认；
(3)上油箱与泵、过滤器之间管路多，连接复杂，所设计的管路多为三维空间管路，设计难度大。另外，各车型连接方式之间存在差异，每个项目该部分管路都需重新设计，设计周期长，且加工难度大，从而该处管路错误率居高。
(4)管路组装时间长。往往由于工艺误差、管路，查找合适的管路等原因，普通车上小柴油机组燃油管路安装周期需要5～7天，而发电车3台发电机组的燃油管路安装周期甚至达到12～15天。
可见，现有的燃油附属设备及管路安装方式，已不能满足节拍生产要求，需要用模块化的设计理念，优化燃油设备安装结构、方式，提高车辆组装效率。
现有的KD25G、KD25K等发电车以及装配有小功率发电机组的轨检车、特种车均需配置燃油附属设备，但燃油系统附属设备没有形成标准化、规范化、模块化,所有这些车型的燃油附属装置都不能做到互装、互换,基本是各车型配装、配用。这些燃油附属装置的差异，给制造、组装以及用户维修等造成很大不方便。模块化思维方式的引进,有助于车辆制造工艺水平的提升。燃油附属设备的设计、制造实现标准化、规范化、模块化以后,使总组装的若干工序转为前置工序,化零部件为模块,再将各模块整组装车，模块化的设计理念,对净化总组装环境,提高部件组装质量水平都有很大帮助。
发电车燃油系统包括有一个下油箱、一个上油箱、一台手摇泵、两台电动油泵(互为备用)、四个浮球液位控制器、柴油滤清器、磁滤器、油水分离器、阀门及管路。轨检车、特种车燃油系统则包括有一个下油箱、一个上油箱、一台手摇泵、两台电动油泵(互为备用)、柴油滤清器、磁滤器、油水分离器、阀门及管路。可见两者燃油系统具有部分相同的组成及连接关系。因此，发明人设想能否把共有的部分做成独立的模块，安装在不同的车型上，有助于提高车辆的模块化程度和车辆的生产效率。

安装时，将模块化燃油输送装置整体从活顶吊装进入机房内部，将支架与机房钢结构预埋螺栓固定，最后与上油箱、下油箱、机组供油管路相连接即可。
本实用新型将油泵、柴油滤清器、磁滤器、油水分离器等设备，合理的安装在设计的共用支架上。模块化上口设置3个管接头，与上油箱连接；共用支架下口设置4个管路接口，分别与机组和下油箱相连。本实用新型通过对现有的燃油系统进行了优化，精简了管路接口，与原有设计相比，上油箱管路接口减少了3个，下油箱接口减少了1个。
