The invention provides a semitrailer traction device, and relates to the technical field of traction equipment.The semitrailer traction device comprises a positioning column arranged at the center line of a semitrailer, a connecting assembly with one end rotationally connected to the positioning column and a traction mechanism connected to the other end of the connecting assembly, and the traction mechanism is connected to the semitrailer in a circumferential sliding mode with the positioning column as the center axis; the traction mechanism is close to the end, connected with the tractor, of the semitrailer and comprises a traction pin and a lifting assembly used for driving the traction pin to vertically move. And the limiting mechanism is used for limiting the traction mechanism at the center line of the semitrailer. The method has the effect of improving the problem that in the prior art, semitrailers and tractors of different models cannot be cooperatively used.

    本发明提供了一种半挂车牵引装置,涉及牵引设备技术领域,其包括设置于半挂车中心线处的定位柱、一端转动连接于定位柱的连接组件以及连接于连接组件另一端的牵引机构,所述牵引机构以定位柱为中心轴周向滑动连接于半挂车,且所述牵引机构靠近半挂车与牵引车连接的一端,所述牵引机构包括牵引销和用于驱动牵引销进行竖向移动的升降组件;还包括用于将牵引机构限位于半挂车中心线处的限位机构。本发明具有改善现有技术中存在不同型号的半挂车和牵引车不能协同使用的问题的效果。
