随着科学技术的进步，公路隧道数量越来越多，甚至隧道增长率高于高速公路本身增长率。隧道受地质条件、设计和施工技术条件的限制，存在很多问题。从已建成的公路隧道看，渗漏水，衬砌开裂，拱背空洞，衬砌厚度不够，混泥土强度劣化等现象较为严重。目前有些公路隧道处于病害发育的亚健康状态，很多隧道已经进入到养护维修期。常见隧道养护的内容包括：土建工程检修(衬砌开裂、渗漏水等)；照明、通风、监控设备检修；机电、消防救援设施检修等。目前我国很多隧道已经进入到养护维修期。
目前隧道养护作业时2米以下的高度，不借助作业平台，但是2米以上位置不借助作业平台根本无法实现，隧道施工人员主要是靠在地面搭脚手架、货车尾部搭载临时脚手架和使用普通高空作业车三种方式来实现，把施工作业人员从地面运送到高处隧道面。搭脚手架的方法高度固定，不可调节；货车尾部脚手架与车厢连接不稳，车辆行走时脚手架晃动剧烈，作业人员安全性没有保障，作业效率低。普通高空作业车作业斗小、承载能力小，只能实现点对点检测，不能一边行走一遍作业，作业效率低；另一方面，作业时臂架结构旋转超出车身宽度占用两个车道，影响车辆通行。

根据图1-图4所示的一种自行走隧道养护作业车，包括汽车二类底盘1、副车架2、自行走装置3和作业装置4，所述副车架2连接于汽车二类底盘1上，副车架2的宽度不超过汽车二类底盘1的车体，所述自行走装置3包括固定于副车架2底部的四个支腿31，支腿31下面通过油缸连接活动腿32，活动腿32底部安装行走轮33，行走轮33内安装马达和轮边减速机，行走轮33作为主动轮带动副车架2行走。所述作业装置4为多平台可折叠作业装置，包括能够在水平方向和竖直方向展开的多个作业平台，所述多个作业平台展开状态能够覆盖四分之一圆弧面，所述作业装置4底部通过第一回转机构5与副车架2连接，第一回转机构5设置于副车架2中心位置，回转角度范围为±90度，使作业装置4可以双侧作业，解决了单向车道高速公路上不能掉头的问题。
本实施例所述作业装置4包括伸缩臂41，所述伸缩臂41包括基本臂411和展开臂412，所述基本臂411的一端连接配重块42，另一端滑动连接展开臂412，所述第一回转机构5设置于基本臂411底部，第一回转机构5的中心与配重块42外边缘的距离不超过副车架2宽度的1/2，使作业装置回转时配重块始 终在车体内，保证作业时只占用一个车道，不影响正常的车辆通行。所述展开臂412的自由端固定连接变幅作业机构44，自由端内侧通过第二回转机构45转动连接第一作业平台43的一端，所述第二回转机构45的回转角度范围为±90度，使第一作业平台43能够在水平方向展开，且可以沿隧道方向伸向后方，增加隧道作业面积；作业装置4收起状态下所述第一作业平台43和变幅作业机构44的长度方向与伸缩臂41同向设置。
上述第一作业平台43包括平台底板431和护栏432，护栏432设置于平台底板边缘，平台底板431靠近第二回转机构45一端设有活动扶梯433和固定爬梯434，方便工人进入平台以及在各平台间移动，所述活动扶梯433与平台底板431转动连接，使其既能向平台内折叠又能向平台外下放。
上述变幅作业机构44包括变幅主臂441，所述变幅主臂441的一端铰接有连接台443，另一端安装有第三作业平台444，中间平行间隔安装3个第二作业平台445，所述连接台443顶部安装有固定作业平台446，底部固定于展开臂412上，变幅主臂441与连接台443之间设有变幅油缸448用来举升变幅主臂441，所述第三作业平台444、第二作业平台445和固定作业平台446在变幅主臂441举升时由上至下呈阶梯状分布。所述变幅主臂441两侧与其平行设置两条连杆442，连杆442的两端分别连接第三作业平台444和连接台443，所述连接台443、第二作业平台445和第三作业平台444均通过安装座447与变幅主臂441和连杆442铰接。具体为所述变幅主臂441和连杆442上同间距错位设置若干组铰点，每一组铰点均连接一个安装座447，相邻安装座447与变幅主臂441、连杆442形成角度可变的平行四边形结构，使多个作业平台在收起状态下齐平，在工作状态下随变幅主臂441的抬升从齐平逐渐呈现阶梯状排布，且作业平台的脚 踩面始终处于水平状态，连接台包括连接柱，连接柱顶部安装固定作业平台446，底部通过螺栓固定于展开臂412上，连接柱上部通过安装座447与变幅主臂441、连杆442和变幅油缸448铰接。
本实施例沿伸缩臂41方向第三作业平台444的宽度大于第二作业平台445的宽度，第一作业平台43的长度大于第二作业平台445的长度，可以解决隧道顶部和底部作业量大的问题，增大作业面积，提高作业效率。呈阶梯布置的第二作业平台445和固定作业平台446，刚好可以覆盖拱腰位置，第三作业平台444覆盖隧道的顶部，第一作业平台43覆盖隧道底部，实现了隧道半断面同时作业，装置收回时，装置平台分成两层布置，第一作业平台43在底层，第二作业平台445、固定作业平台446和第三作业平台444水平布置在第一作业平台43上方，收车时占用空间小，外观简洁。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本发明的保护范围。
