The invention provides a pull arm upper assembly lifting hook structure with a buffering function, which comprises a vehicle body, a lifting arm upper assembly and a box body, the lifting arm upper assembly is fixedly mounted on the top of the vehicle body, the box body is arranged on the top of the lifting arm upper assembly, a pull handle is arranged on one side of the box body, and the two sides of the pull handle are movably connected with limiting blocks through rotating shafts. And one side of the limiting block is fixedly connected with one side of the box body. The buffering lifting hook mechanism can play a buffering role when a lifting hook pulls a box body in the suspension arm, the situation that the lifting hook is damaged due to the fact that contact is affected is avoided, and meanwhile the adjusting mechanism and the stabilizing mechanism can solve the problem that when the suspension arm in the vehicle body pulls the box body to be loaded on the vehicle body, if some protruding obstacles exist at the bottom of the box body, the box body cannot be damaged. When the box body is pulled to move, the box body jolts, the stability of the box body cannot be guaranteed, and rollover is caused, and the anti-falling mechanism can avoid unhooking caused by jolting in the process of pulling the box body to move.
本发明提供一种具有缓冲功能的拉臂上装吊钩结构,包括车体、吊臂上装和箱体,所述吊臂上装固定安装于车体顶部,所述箱体设置于吊臂上装的顶部,所述箱体的一侧设置有拉把,所述拉把的两侧均通过转轴活动连接有限位块,所述限位块的一侧与箱体的一侧固定连接。本发明中缓冲吊钩机构能够在吊臂上装中吊钩牵引着箱体时对起到缓冲的作用,避免影响接触导致吊钩损坏,同时调整机构和稳固机构,能够解决车体中吊臂上装牵引着箱体向车体上装载时,若箱体的底部存在着一些凸起的障碍物时,会导致箱体发生颠簸,无法保证箱体稳定性,导致侧翻情况发生,且防脱机构能够避免牵引箱体移动过程中,因为颠簸导致脱钩的情况发生。
