The variable-width crawler-type chassis structure comprises a fixed chassis, two movable chassis bodies and a crawler assembly, a fixed block is fixedly arranged on the outer wall of the fixed chassis, a transmission cavity is formed in the fixed block, and a first transmission shaft is rotationally arranged in the transmission cavity through a first motor; and a plurality of screw rods extending to the outer wall of the fixing block are further rotationally arranged in the transmission cavity, the multiple screw rods are connected with the first transmission shaft through first rotating mechanisms, the outer walls of the multiple screw rods are in threaded connection with connecting rods, and the multiple connecting rods are matched with the fixing block through limiting mechanisms. By arranging the fixed chassis, the movable chassis, the screw rod, the connecting rod and the like, rotation of the screw rod can be achieved by means of the assemblies, movement of the connecting rod relative to the fixed block is achieved by means of rotation of the screw rod, therefore, distance adjustment of the crawler belt assemblies on the two sides is achieved, and it is guaranteed that the operation vehicle adapts to different road surface environments and smoothly moves.

    本发明公开了一种高空作业车可变宽度的履带式底盘结构,包括固定底盘、两个活动底盘与履带组件,所述固定底盘外壁固定设有固定块,所述固定块内设有传动腔,所述传动腔内通过第一电机转动设有第一传动轴,所述传动腔内还转动设有多根延伸至固定块外壁的螺杆,多根所述螺杆均通过第一转动机构与第一传动轴连接,多根所述螺杆外壁均螺纹连接有连接杆,多根所述连接杆均通过限位机构与固定块配合。本发明通过设置固定底盘、活动底盘、螺杆与连接杆等,能借助上述组件实现螺杆转动,借助螺杆转动实现了连接杆现对于固定块的移动,从而实现两侧履带组件的间距调节,保证作业车适应不同路面环境顺利移动。
