本公开的一些实施例提出一种提升作业效率的轮式工程车辆，用于缓解稳定差的问题。
参考图1，挖掘装载机包括挖掘作业端20和装载作业端30。其中，挖掘作业端20包括挖掘用挖掘臂和挖斗，装载作业端30包括装载用装载臂和铲斗。由于挖掘装载机在进行挖掘工作时，需要与地面刚性接触，以避免整车发生晃动，因此，挖掘装载机上设有支撑装置，通过支撑装置支撑地面，以将整车支撑起来，使轮胎抬离地面。
支撑装置一般包括设于挖掘作业端20两侧的支腿，为满足复杂地面工况的挖掘作业需求，尤其是高低不平野外工况的施工作业需求，对整车稳固性要求很高，需要尽量增大两个支腿的支撑跨度和支撑高度。
基于此，如图2所示，本公开一些实施例提供了一种提升作业效率的轮式工程车辆，轮式工程车辆包括支撑装置，通过设置支撑装置提高轮式工程车辆支撑的稳定性。其中，支撑装置包括架体1、第一伸缩缸2和支腿组件3。
架体1被配置为设于轮式工程车辆的车架上，或者，架体1被配置为与轮式工程车辆的车架一体。
第一伸缩缸2设于架体1。支腿组件3与第一伸缩缸2驱动连接，支腿组件3被配置为在第一伸缩缸2的驱动下相对于架体1转动。当第一伸缩缸2驱动支腿组件3相对于架体1向上转动，收拢于车架侧部时，不会超过整车尺寸范围；当第一伸缩缸2驱动支腿组件3相对于架体1向下转动接触地面时，支腿组件3用于支撑轮式工程车辆，将整车支撑起来，使轮式工程车辆的轮胎抬离地面。
如图3所示，支腿组件3包括第一支腿31，第一支腿31被构造为空心结构，第一支腿31的第一端与架体1铰接，第一支腿31的第二端为自由端。

第二支腿34被配置为在第二伸缩缸32的驱动下相对于第一支腿31伸出或缩回，且第一支腿31被构造为对第二支腿34径向限位。第二支腿34受到的径向力传递至第一支腿31，继而通过第一支腿31传递至架体1，以避免对第二伸缩缸32产生径向力或弯矩使第二伸缩缸32发生变形，因此，利于第二伸缩缸32的正常工作，提高了 第二伸缩缸32的使用寿命。第一支腿31用于保护第二伸缩缸32，且用于对第二支腿34的伸缩进行导向。第一支腿31具有主力支撑作用，第一支腿31与第二支腿34配合支撑整车，提高了整车的稳定性。
在一些实施例中，第二支腿34与第二伸缩缸32可旋转地连接。
第二支腿34在第二伸缩缸32的驱动作用下，可相对于第一支腿31伸缩，用于实现不同的支撑跨度；且第二支腿34可相对于第二伸缩缸32旋转，使第二支腿34可满足任意角度的工况，始终使支撑盘36保持与地面完全接触，提高施工作业过程中车辆支撑的稳定性，提升作业效率。
在一些实施例中，支腿组件3包括轴承33，第二支腿34通过轴承33连接第二伸缩缸32，用于实现第二支腿34相对于第二伸缩缸32的旋转。

在一些实施例中，第二支撑件37包括弹性材料制成的弹性件371。
对于表面较好地水泥路面或者路面要求较高的地方，为了避免支撑盘36对路面造成损伤，支撑盘36的其中一个支撑面设置弹性件371，通过弹性件371支撑地面，以避免损坏地面。
可选地，弹性件371包括橡胶垫。
在一些实施例中，第二支撑件37包括齿型件372。可选地，齿型件372采用钢材制成。

在一些实施例中，定位结构包括定位件381，设于支撑盘36的至少两个第一定位孔382，以及设于第二支腿34的第二定位孔383。在其中一个第二支撑件37支撑地面时，至少两个第一定位孔382中的一个第一定位孔382与第二定位孔383对齐，定位件381被配置为插入第一定位孔382和第二定位孔383，以锁定支撑盘36与第二支腿34。
在一些实施例中，第二支腿34的第二端341通过铰接轴与支撑盘36铰接，第二支腿34与支撑盘36的铰接位置位于第二支腿34的轴向上。第二支腿34的第二端341设置的第二定位孔383偏离第二支腿34的轴向。
在一些实施例中，如图3所示，第二支腿34的第二端341被构造为折弯状，第二端341的折弯处通过销轴与支撑盘36铰接，第二支腿34与支撑盘36的铰接位置位于第二支腿34的轴向上。第二定位孔383设于第二端341折弯后的端部，第二定位孔383偏离第二支腿34的轴向，在插入定位件381连接定位支撑盘36和第二支腿34后，支撑盘36能够相对于第二支腿34小幅度旋转，以调整角度适用于高低不平的地面。
支撑盘36与第二支腿34铰接，虽然通过定位件381将支撑盘36与第二支腿34定位，但支撑盘36相对于第二支腿34仍可以小幅转动；在第二支腿34支撑过程中，避免地面角度不同造成车辆前后倾斜时，使支撑盘36与地面不平行，并且，即使第 二支腿34与地面之间存在角度变化，由于第二支腿34相对于第一支腿31可旋转，支撑盘36可相对于第二支腿34小幅转动，也可以保证支撑盘36与地面在左右方向的动态平行，增加接触面积，有效应对车辆作业过程中的角度变化，保证支撑盘36与地面的平行，提高稳定性。
在一些实施例中，支撑盘36设有至少两个结构不同的第二支撑件37，可针对不同工况地面快速灵活切换，尤其对于软土地面施工时，可避免支撑盘36抓地力不足造成的整车滑移或侧倾，大大提高了整车的作业稳定性和施工工作效率。
