The telescopic boom frame comprises a guide frame, a third hydraulic cylinder and a mounting plate, a first moving plate is movably mounted on the inner side of the guide frame, the third hydraulic cylinder is mounted at the bottom of the guide frame, and a supporting assembly is mounted at the output end of the third hydraulic cylinder. And the supporting assembly is used for supporting the first moving plate and comprises a second moving plate and a fourth hydraulic cylinder, the fourth hydraulic cylinder is installed at the bottom of the second moving plate, a mounting plate is installed at the output end of the fourth hydraulic cylinder, and a plurality of first universal wheels are installed at the bottom of the mounting plate. When heavy goods are hoisted, a fourth hydraulic cylinder can drive a mounting plate to move downwards, then first universal wheels make contact with the ground, accordingly, a second moving plate can be supported, meanwhile, the second moving plate can support a first moving plate, the situation that the first moving plate is bent downwards due to large pressure is avoided, and the service life of the first moving plate is prolonged. Goods are hung through the hook.

    本发明公开了一种轮胎式堆料机用的伸缩臂架,包括导向框、第三液压缸和安装板,所述导向框的内侧活动安装有第一移动板,所述导向框的底部安装有第三液压缸,所述第三液压缸的输出端安装有支撑组件,支撑组件用来对第一移动板进行支撑,所述支撑组件包括第二移动板和第四液压缸,所述第二移动板的底部安装有第四液压缸,所述第四液压缸的输出端安装有安装板,所述安装板的底部安装有多个第一万向轮。本发明当吊运较重的货物时,可以通过第四液压缸带动安装板下移,然后使第一万向轮接触地面,从而实现对第二移动板的支撑,同时第二移动板又可以对第一移动板进行支撑,避免第一移动板受到较大的压力而向下弯曲,通过挂钩将货物吊起来。
