The invention discloses an adjustable chassis of an excavator and a using method of the adjustable chassis. The adjustable chassis comprises a base and crawler belts arranged on the base, wherein telescopic mechanisms are fixedly installed at the bottom of an inner cavity of the base, and a drawing plate is fixedly connected to the surface of the output end of each telescopic mechanism. The invention relates to the technical field of excavators. According to the adjustable chassis of the excavator and the using method of the adjustable chassis, the drawing plates are connected to the telescopic mechanisms, and when the telescopic mechanisms retract, the drawing plates can be driven to move, then first pulling plates drive side sliding plates to move, the maximum transverse supporting size of the two side sliding plates to the crawler belts is shortened; and meanwhile, second pulling plates extrude adjusting plates, and the adjusting plates move to support the crawler belts, so that the purpose of controlling the shape change of the crawler belts is achieved, and therefore, after the base is lifted and the distance between the base and the ground is increased, the crawler belts can run in more complex environments, a transfer vehicle is not used any more in a small-range complex environment, the operation is simple, and the use is more convenient.
本发明公开了一种挖掘机可调底盘及其使用方法,包括底座和设置在底座上的履带,所述底座内腔的底部固定安装有伸缩机构,所述伸缩机构的输出端的表面固定连接有抽拉板,本发明涉及挖掘机技术领域。该挖掘机可调底盘及其使用方法,通过在伸缩机构上连接抽拉板,在伸缩机构收缩时,可以带动抽拉板移动,进而通过第一拉板带动侧滑板移动,缩短两个侧滑板对履带的横向最大支撑尺寸,与此同时,第二拉板挤压调节板,使得调节板移动对履带进行支撑,从而达到控制履带形状变化的目的,这样可以使得底座升高,与地面之间的间距增大后,可以在更多复杂的环境中行驶,在小范围的复杂环境中不再使用转运车辆,操作简单,使用更加方便。
