According to the chassis lifting appliance rear support switching device and the lifting appliance model changing method, a supporting seat of a rear lifting arm of the lifting appliance is provided with a supporting structure, the supporting structure comprises a first supporting block and a second supporting block which are hinged to the supporting seat side by side in the moving direction of the lifting appliance, and the direction of the central axis of the hinged part is consistent with the moving direction of the lifting appliance; the switching device comprises a frame, a first rotating pusher dog assembly and a second rotating pusher dog assembly, wherein the first rotating pusher dog assembly and the second rotating pusher dog assembly are installed on the frame in a sliding mode and used for stirring the first supporting block and the second supporting block to rotate correspondingly. The transverse moving telescopic cylinder is installed on the frame and drives the first rotating pusher dog assembly and the second rotating pusher dog assembly to move between the two rear suspension arms to be close to and away from the supporting structure; and the first rotary pusher dog assembly and the second rotary pusher dog assembly respectively stir the first supporting block and the second supporting block to rotate so as to switch the supporting surfaces. The supporting structure on the lifting appliance can be automatically switched, different skirt edge widths can be adapted, the production efficiency is improved, and meanwhile the labor cost and potential safety hazards are reduced.
一种底盘吊具后支撑切换装置及吊具换型方法,吊具的后吊臂的支撑座上设置有支撑结构,支撑结构包括沿吊具移动方向并排铰接安装于支撑座上的第一支撑块和第二支撑块,且铰接部位中心轴线方向均与吊具移动方向一致,切换装置包括:框架以及滑动安装于框架上的第一旋转拨爪组件和第二旋转拨爪组件,分别用于拨动第一支撑块和第二支撑块转动;安装于框架上的横移伸缩缸,驱动第一旋转拨爪组件和第二旋转拨爪组件在两个后吊臂之间移动,靠近和远离支撑结构;第一旋转拨爪组件和第二旋转拨爪组件分别拨动第一支撑块和第二支撑块转动,切换支撑面。使吊具上支撑结构自动化切换,可以适应不同裙边宽度,提高生产效率,同时降低人工成本和安全隐患。
