Description

一种步履式挖掘机 技术领域
本发明涉及到建筑及其他施工中的一种挖掘机，尤其涉及一种步履式挖掘机。
背景技术
在建筑其他施工中遇见的高于或低于承机面的物料时的挖掘，并装入运输车辆或卸至堆料场的土方机械。存在的问题是：大型挖掘机的行走链板较短导致稳定性较差，行走链板与地面接触面积小，地面承受压力大；行走链板加长后易造成行走链板走折且造价较高。
发明内容
本发明是要解决现有技术存在的上述问题，提供一种配备了专利产品：步履式行走底座(专利号：PCT/CN2014/000823)的一种挖掘机。大大增加了挖掘机的稳定性，对施工环境要求较低。
本发明涉及的步履式挖掘机，其特征是：动力装置与驾驶室安装在步履行走底座上，挖掘机挖掘臂安装在动力装置上，也可安装专利产品：破碎器(专利号：PCT/CN2014/001098)。
该步履式挖掘机的有益效果是：
1、由于发明了该步履式挖掘机，大大增加了挖掘机的稳定性，降低了施工环境的要求，步履式行走装置造价低。
2、安装破碎器，在过硬的岩石、路面、混凝土和施工条件较差的作业时，工作效率增大，降低了施工时间和成本，节约能源。
附图说明
图1为本发明结构示意图；
图2为图1后视图；
图3为安装了破碎器的结构示意图；
图4为步履式行走底座结构示意图；
图5为图4的侧视图。
图中：步履式行走底座1，动力装置2，大臂3，小臂变幅油缸4，小臂5，挖掘铲变幅油缸6，挖掘铲7，大臂变幅油缸8，破碎器9，移动行走支脚10，固定行走支脚11，纵向行走油缸12，轮架13，轮架上滑板(滑轮)14，纵向连接梁15，支脚油缸16，支脚油缸内滑套17，销轴18，支脚油缸外滑套19，轮架轴20，支重轮21，上滑道22。
具体实施方式
下面结合附图和具体实施方式对本发明做进一步详细说明：
如图1、图2所示，该步履式挖掘机，包括动力装置2安装在步履式行走装置1上，挖掘铲7、小臂5和大臂3相连，通过挖掘铲变幅油缸6、小臂变幅油缸4和大臂变幅油缸8连接运动，并安装在动力装置2的上。
通过主机驾驶员的操作，使动力装置2工作，使步履式行走底座1行走至施工地点，通过挖掘机大臂变幅油缸8、小臂变幅油缸4和挖掘铲变幅油缸6的作用下，使挖掘机大臂3、小臂5和挖掘铲7变幅工作，完成挖掘过程。
如图3所示，该步履式挖掘机，还装配有专利产品破碎器9，在动力装置2的带动下进行快速的伸缩运动，在伸缩运动产生的冲击震动力作用下，使岩石、路面、混凝土等快速破碎。
如图4、图5所示，包括动力装置2通过回转支撑轴承和轴承底座与固定行走支脚11连接，固定行走支脚11通过连接销轴18与纵向连接梁15连接，纵向连接梁15与两端的支脚油缸外滑套19固定成为移动行走支脚架，支脚油 缸6一端与支脚油缸外滑套19连接，另一端和支脚油缸内滑套17与轮架13通过轮架轴20连接，轮架13下安装有支重轮21，支重轮21在移动行走支脚10内的下滑道上前后行走，移动行走支脚10通过纵向行走油缸12与移动行走支脚架相连。在底盘前后增加推土铲便于步履式行走底盘在坑洼路段行走。
所述轮架13上安装有滑板(滑轮)14沿上滑道22下滑行，用于移动行走支脚14的前后左右运动。
通过安装在动力装置2上的驾驶室来控制步履式行走底盘。通过控制支脚油缸16的伸缩，来调节移动行走支脚10和固定行走支脚11与地面受力情况的交替运行。通过控制纵向行走油缸12的伸缩达到步履式行走底盘的前后行走和左右转向。在使用机械作业时，可使移动行走支脚10与固定行走支脚11同时与地面接触受力，以达到使用机械的最佳平稳性。
控制支脚油缸16，使支脚油缸16缸杆伸出，带动轮架13产生向下的力，使移动行走支脚10向下与地面接触，提升固定行走支脚11离开地面，支脚油缸16停止运动。
控制纵向行走油缸12的缸杆向前伸缩，带动移动行走支脚10沿轮架13上的滑板(滑轮)14沿上滑道22向前滑动，这一过程在纵向行走油缸12达到最大行程为止。
控制支脚油缸16，使支脚油缸16缸杆缩回，带动轮架13产生向上的力，使移动行走支脚10向上离开地面，固定行走支脚11与地面接触，支脚油缸16停止运动。
控制纵向行走油缸12的缸体向前伸缩，带动支重轮21在移动行走支脚10内的滑道上滚动，这一过程在纵向行走油缸12达到最大行程为止。
步履式行走装置正常行驶时，在一边的纵向行走油缸12停止的情况下，通 过控制另一边纵向行走油缸12的伸缩达到步履行走装置的转向行走。
通过以上一系列的操作使步履式挖掘机在安全平稳的环境下进行行走。
