The invention relates to the technical field of semitrailers, and concretely relates to a lifting support device capable of assisting semitrailer driving. The device comprises a support assembly, a wheel leg assembly, a supporting frame assembly and a power system used for driving the wheel leg assembly to move up and down. The supporting assembly is connected with a connecting assembly used for being connected with a semitrailer, the supporting frame assembly is connected to the bottom of the support assembly and is provided with a through hole, one end of the wheel leg assembly moves in thesupport assembly and is connected with the power system, and the other end of the wheel leg assembly can vertically move to penetrate through the through hole. A transmission assembly used for drivingthe supporting frame assembly to move up and down is connected between the wheel leg assembly and the supporting frame assembly, and the transmission assembly is connected with a switching assembly capable of limiting the transmission effect of the transmission assembly. The wheel leg assembly is driven by the power system to move up and down, the device has the supporting leg function and the auxiliary driving function, and the two functions can be switched through the switching assembly, so the running stability and the operation safety of the semitrailer are effectively improved.

    本发明涉及半挂车的技术领域,更具体地,涉及一种可辅助半挂车驾驶的升降支撑装置,包括支架组件、轮腿组件、撑架组件及用于驱动轮腿组件上下活动的动力系统,支架组件连接有用于与半挂车连接的衔接组件,撑架组件连接于支架组件的底部且撑架组件设有通孔,轮腿组件的一端活动于支架组件内且与动力系统连接,轮腿组件的另一端可上下活动穿过所述通孔;所述轮腿组件及撑架组件之间连接有用于驱动撑架组件上下活动的传动组件,所述传动组件连接有可限制传动组件传动作用的切换组件。本发明通过动力系统驱动轮腿组件上下活动,同时具有支撑腿功能和辅助驾驶功能,且两种功能之间可通过切换组件进行切换,有效改善半挂车的行驶平稳性及操作安全性。
