The invention relates to the technical field of engineering machinery, and provides a guide wheel device, a crawler device and an operation machine.The guide wheel device comprises a guide wheel, a mounting base, a supporting base and an adjusting mechanism; the mounting seat is used for being connected with a lower vehicle frame and is provided with a mounting space for mounting the guide wheel; the supporting seats are distributed on the two sides of the guide wheel in the axis direction of the guide wheel, the supporting seats are in sliding fit with the mounting seat, the sliding direction is arranged in the height direction of the lower vehicle frame, and the guide wheel is arranged on the supporting seats in the mode of rotating around the axis of the guide wheel; the adjusting mechanism is arranged between the supporting seat and the mounting seat, the adjusting mechanism can be switched between an adjusting state and a keeping state, in the adjusting state, the adjusting mechanism can drive the supporting seat to slide relative to the mounting seat, and in the keeping state, the adjusting mechanism limits the supporting seat to slide relative to the mounting seat. By means of the arrangement, the problem that in the prior art, the installation height of the guide wheel on the lower vehicle frame of an excavator cannot be adjusted is solved.

    本发明涉及工程机械技术领域,提供一种引导轮装置、履带装置及作业机械,其中,引导轮装置包括引导轮、安装座、支撑座和调节机构;安装座用于与下车架相连接,安装座具有用于安装引导轮的安装空间;支撑座设置有一对,一对支撑座沿引导轮的轴线方向分布于引导轮的两侧,支撑座与安装座滑动配合,滑动方向沿下车架的高度方向设置,引导轮可绕自身轴线转动地设置于支撑座;调节机构设置于支撑座与安装座之间,调节机构能够在调节状态与保持状态之间切换,在调节状态,调节机构能够带动支撑座相对于安装座滑动,在保持状态,调节机构限制支撑座相对于安装座滑动。如此设置,解决了现有技术中的挖掘机因引导轮在下车架上的安装高度不可调节的问题。
