The invention discloses an air bag type pulling trolley comprising a rack. The rack comprises a carrying platform; an air bag arranged among four supporting legs is arranged below the middle of the carrying platform. A plurality of supporting rollers are arranged at the bottom of the carrying platform and on the inner sides of the supporting legs; a high-pressure gas main pipeline penetrates the carrying platform, a high-pressure gas connector is arranged at the end of the high-pressure gas main pipeline, the high-pressure gas main pipeline is in rotary sealing connection with an inflation anddeflation connector through a hose; and a traction base is arranged at the end of the rack. The trolley has the beneficial effects that: because the airbag rolls under tension after being inflated, pulling transportation of carried objects is realized; on the basis of a design of walking wheels, the risk that the trolley suddenly sits on the bottom can be reduced, so that the use stability and safety are improved; a problem of repeated inflation and deflation can be solved by the adoption of an air pressure control valve, so that the use efficiency of the air bag is improved, and the servicelife of the air bag is prolonged.
一种气囊式拉移台车,包括机架,机架包括载物平台,载物平台中部下方设置有位于四个支撑腿之间的气囊,载物平台底部和支撑腿内侧均设置有若干支撑辊筒,载物平台内贯穿有高压气体主管路,高压气体主管路端部设置有高压气体接口,高压气体主管路通过软管与充放气接口旋转密封连接,机架端部设置有牵引座。本发明的有益效果是:通过气囊充气后受到拉力滚动的原理,实现了载重物的拉移运输,采用行走轮的设计可以降低台车突然坐底的风险,提高了使用的稳定性和安全性,采用气压控制阀可以避免反复的充放气问题,提高了气囊的使用效率,延长了气囊的使用寿命。
