The invention discloses a lifting bridge air bag suspension system which comprises a bearing air bag, a lifting air bag, a lifting mechanism support, an air storage tank and a pneumatic control device, the pneumatic control device comprises a two-position five-way electromagnetic valve, when a lifting bridge is controlled to descend, the two-position five-way electromagnetic valve is located at a first working position, an air inlet P is communicated with the air storage tank, and an air outlet P is communicated with the air storage tank; the first working port is communicated with the bearing air bag, and the air storage tank inflates the bearing air bag; when the lifting bridge is controlled to lift, the two-position five-way electromagnetic valve is located at a second working position, the air inlet is communicated with the bearing air bag, the second working opening is communicated with the lifting air bag, and the bearing air bag inflates the lifting air bag. The lifting air bag is inflated through the bearing air bag, the utilization rate of compressed air is increased, and energy consumption is reduced. And the size of the gas storage tank is reduced, the cost is reduced, and the arrangement of the gas storage tank is facilitated.
本发明公开了一种提升桥气囊悬架系统,包括承载气囊、提升气囊、提升机构支架以及储气罐和气动控制装置,所述气动控制装置包括二位五通电磁阀,当控制提升桥下降时,所述二位五通电磁阀处于第一工作位,进气口P连通储气罐,第一工作口连通所述承载气囊,储气罐向承载气囊充气;当控制提升桥提升时,所述二位五通电磁阀处于第二工作位,进气口连通所述承载气囊,第二工作口连通所述提升气囊,承载气囊向提升气囊充气。本发明,利用承载气囊向提升气囊充气,提高了压缩气体的利用率,降低了能源消耗。并且减小了储气罐的体积,降低了成本,方便了储气罐的布置。
