The light-weight semitrailer comprises a mounting plate, when the light-weight semitrailer is used, a square hole round pipe can be driven to rotate by starting a servo motor, the square hole round pipe rotates to drive a square rod to rotate, a transmission rod is driven to rotate, the transmission rod rotates to drive a rotating shaft to rotate through meshing of a transmission bevel gear and a driven bevel gear, and therefore the light-weight semitrailer is driven to rotate. Then, two second air cylinders are started to push two lifting blocks to move downwards, so that a plurality of bearing plates make contact with the ground, then, two first air cylinders are started to pull two supporting plates to be far away from each other, and the two supporting plates make contact with the ground; and the bottoms of the two supporting plates are attached to the tops of the adjacent rectangular blocks correspondingly, so that the middle position of the semitrailer can be supported when cargoes are loaded and unloaded, the situation that the middle of a carriage is broken due to stress is effectively avoided, and meanwhile the situation that a rotating shaft is broken due to too large bearing capacity is avoided.
本发明公开了一种带有支承装置的轻量化半挂车,包括安装板,本发明在使用时,通过启动伺服电机可带动方孔圆管旋转,方孔圆管旋转带动方杆旋转,并带动传动杆旋转,传动杆旋转通过传动锥形齿轮与从动锥形齿轮的啮合带动转轴旋转,并带动相邻的空心筒向下翻转,从而使得两个空心筒与地面垂直,接着,启动两个第二气缸推动两个升降块向下移动,从而将若干个承重板与地面相接触,然后,启动两个第一气缸拉动两个支撑板相远离,并使得两个支撑板的底部分别与相邻的矩形块顶部贴合,从而可在装卸货物时对半挂车中部位置支撑,有效的避免车厢中部受力闪断,同时,避免承载力过大造成转轴的断裂。
