The invention provides a track-gauge-changeable crawler-type power platform. The track-gauge-changeable crawler-type power platform comprises a power platform chassis, a crawler walking device and a track-gauge-changeable adjusting mechanism. The power platform chassis is connected with the crawler walking device through the front connecting rod and the rear connecting rod, one end of the hydraulic oil cylinder is connected with the front connecting rod, the other end of the hydraulic oil cylinder is fixed to the power platform chassis, and the power platform drives the crawler walking device to transversely get close to or away from the power platform chassis through the variable gauge adjusting mechanism. Therefore, the transverse distance between the crawler walking devices on the two sides is changed, and the gauge-changeable adjusting mechanism can continuously adjust the gauge between the two crawler walking devices, the ground clearance of the power platform chassis and the gravity center of the power platform. The track gauges can be adjusted at the same time or independently according to needs, the trafficability of the whole vehicle is high, the posture of the whole vehicle can be leveled to a certain degree when the vehicle operates or walks on a slope along a contour line, the longitudinal stability can be improved by adjusting the front-back position of the gravity center when the vehicle goes up and down a steep slope, and the requirements of different crop agriculture on machines and tools under complex working conditions of hills and mountains are met.
本发明提供一种可变轨距履带式动力平台,包括动力平台底盘、履带行走装置以及变轨距调节机构;动力平台底盘通过前、后连接杆连接履带行走装置,液压油缸一端与前连接杆连接,另一端固定在动力平台底盘上,动力平台通过变轨距调节机构带动履带行走装置横向靠近或远离动力平台底盘,从而改变两侧履带行走装置之间的横向距离,变轨距调节机构可连续调节两履带行走装置之间的轨距、动力平台底盘离地高度与动力平台的重心。本发明中轨距可同时调节或根据需要单独调节,整车通过性高,在坡地沿等高线作业或行走时可实现一定程度的整车姿态调平,上下陡坡时可通过调整重心前后位置提高纵向稳定性,满足丘陵山地复杂工况下不同作物农艺对机具的需求。
