The invention relates to the technical field of automobile manufacturing, in particular to a trailer airbag axle lifting device which is characterized in that during working, a main airbag part is fixed through a mounting plate, then a plurality of auxiliary airbag parts are mounted on the outer side of the main airbag part, and the auxiliary airbag parts are controlled through a first pressure valve and a second pressure valve respectively; during use, the inflation pump is started to inflate the inflation cavity, at the moment, the second pressure valve is opened to rapidly inflate the multiple auxiliary air bag parts, due to the fact that the cavity size of the auxiliary air bag parts is small, rapid inflation is achieved, the axle is pushed away, rapid supporting is achieved, then pressure continues to be increased, the second pressure valve is opened, and the auxiliary air bag parts are rapidly inflated. And after the main air bag piece is filled with the air, an air release valve, a first pressure valve and a second pressure valve which are arranged on the air inflation cavity are opened to release redundant high-pressure air, so that supporting is better provided within a safety range. And when the air support is released, the vent valve is directly opened to exhaust all the air, so that the use is more convenient.
本发明涉及汽车制造技术领域,具体涉及一种挂车气囊车桥提升装置,工作时通过安装板对主气囊件进行固定,然后在主气囊件外侧安装有多个辅助气囊件,并分别通过第一压力阀和第二压力阀进行控制,使用时启动充气泵向充气腔体中充气,此时第二压力阀打开以快速对多个辅助气囊件进行充气,由于辅助气囊件的腔体体积比较小,从而快速充气,以将车桥推开,从而快速进行支撑,然后继续提升压力使得第二压力阀打开,从而继续对主气囊件进行充气,以使得更一步提升支撑力,待主气囊件充满后,打开充气腔体上设置的放气阀以及第一压力阀和第二压力阀以放出多余的高压气体,使得在安全范围内更好的提供支撑。而在解除空气支撑时则直接打开放气阀以将所有气体排出,使得使用更加方便。
