The invention relates to a vehicle emergency device, in particular to an emergency operation platform for a semitrailer. Theemergency operation platform comprises a mounting platform and a lifting platform, the mounting platform is mounted on a frame, the lifting platform is slidably connected to the mounting platform, and a turnover structure is arranged on the side, facing the ground, of the lifting platform. The overturning structure is used for driving supporting wheels to overturn so that the supporting wheels can vertically face the ground, meanwhile, telescopic assemblies in the overturning structure drive wedge-shaped blocks to slide and cooperate with inclined faces arranged at the tail ends of first sliding ways in the mounting platform to drive the lifting platform to descend, and the supporting wheels abut against the ground to conduct auxiliary supporting operation. The problems that in the prior art, when the situation that springs are broken, shafts are broken and other single-side supporting capacity of the semitrailer are lost, a semitrailer body is out of control, and rollover and other dangerous situations are likely to happen are solved.

    本发明涉及一种车辆应急装置,具体是一种半挂车用应急作业平台,包括安装平台以及升降平台,其中所述安装平台安装在车架上,所述升降平台滑动连接在安装平台上,所述升降平台朝向地面侧设置有翻转结构,翻转结构用于带动支撑轮翻转,使其垂直朝向地面,同时翻转结构内的伸缩组件带动楔形块滑动,配合安装平台内第一滑道末端设置的斜面,带动升降平台下降,使得支撑轮与地面抵接,进行辅助支撑作业,以解决目前当半挂车发生断簧和短轴等单侧失去支撑能力的情况下,车体失去控制,容易导致侧翻等等危险情况的问题。
