The invention provides a guide wheel mechanism, a driving device and an excavator, and relates to the field of engineering machinery. The guide wheel mechanism comprises a guide base, an adjusting piece arranged on the guide base and a guide wheel rotationally connected to the adjusting piece, and the adjusting piece has a first posture and a second posture which can be switched relative to the guide base. The axis of the guide wheel when the adjusting piece is in the first posture is higher than the axis of the guide wheel when the adjusting piece is in the second posture. Therefore, the height of the adjusting piece is adjusted according to the installation requirements of different types of crawler belts, so that the height of the guide wheel is adjusted, the installation requirements of different crawler belts are met, and after different crawler belts are installed, good stability and comfort are achieved. The driving device and the excavator both comprise the guide wheel mechanism, and therefore the driving device and the excavator have the advantage of being capable of adapting to installation of different types of crawler belts.

    本申请提供了一种引导轮机构、驱动装置和挖掘机,涉及工程机械领域。本申请提供的引导轮机构,包括导向座、设置于导向座的调节件以及转动连接于调节件的引导轮,调节件相对于导向座具有可切换的第一姿态和第二姿态,调节件处于第一姿态的情况下引导轮的轴线高于调节件处于第二姿态的情况下引导轮的轴线。因此,根据不同种类履带安装需要,调节调节件的高度,从而调节引导轮的高度,满足不同履带的安装需求,使得在安装不同的履带之后,均具有较佳的稳定性和舒适度。本申请提供的驱动装置和挖掘机均包括了上述的引导轮机构,因此,也具有能够适应安装不同种类的履带的优点。
