The invention discloses a rollover truck air bag type righting device and method. The rollover truck air bag type righting device comprises an air bag type jack and an air bag type buffering cushion. The air bag type jack is arranged on the lower portion of the dumping side of the rollover truck and cooperates with the crane to achieve lifting and overturning of the truck body. The air bag type buffer cushion is arranged in a landing area in the aligning direction, and a multi-stage damping mechanism is arranged in the air bag type buffer cushion so as to absorb impact energy and achieve stable landing through controllable deflation. According to the air bag type jack, the independent air pump unit is combined with an inertial sensor and pressure feedback, the inflation rate is dynamically adjusted through the central controller, uniform bearing force distribution of a vehicle body structure is achieved in the centralizing process, and secondary damage caused by local stress concentration is effectively prevented. When the truck returns to fall down, the pre-inflated airbag cushion pad achieves progressive absorption of impact energy in a multi-stage damping and graded pressure relief mode, in the initial stage, the internal pressure of the airbag is used for buffering instantaneous impact, and then the truck stably falls to the ground through controllable deflation. According to the invention, a modular quick-release design is adopted, parallel operation of multiple devices is supported, the accident rescue efficiency is improved, secondary damage is reduced, and the device is suitable for righting rescue scenes of various heavy vehicles.

    本发明公开了一种侧翻卡车气囊式扶正装置及方法,装置包括气囊式千斤顶和气囊式缓冲垫。气囊式千斤顶布设于侧翻卡车倾倒侧下方,与吊车协同作用,实现车身抬升及翻转;气囊式缓冲垫布设于回正方向的落地区域,内部设有多级阻尼机构,以吸收冲击能量并通过可控放气实现平稳落地。气囊式千斤顶利用独立气泵单元结合惯性传感器和压力反馈,由中央控制器动态调节充气速率,扶正中实现车身结构的均匀承力分布,有效防止局部应力集中造成的二次损伤。当卡车回正下落时,预充气的气囊缓冲垫通过多级阻尼分级泄压方式实现冲击能量渐进式吸收:初始阶段利用气囊内压缓冲瞬时冲击,随后通过可控放气使车辆平稳落地。本发明采用模块化快拆设计,支持多设备并行操作,提升事故救援效率,减少二次损伤,适用于各类重型车辆扶正救援场景。
