The invention relates to the technical field of pneumatic lifting devices, and discloses a pneumatic lifting device with a stable structure, the pneumatic lifting device comprises a fixing frame and a lifting tray, the fixing frame comprises an ejector rod, the bottom of the ejector rod is fixedly connected with a fixing frame, and the two ends of the fixing frame are fixedly connected with mounting lugs respectively; a lifting groove is formed in the inner side wall of the fixing frame, two air cylinders are fixedly connected to the bottom of the ejector rod, the bottoms of the two air cylinders are fixedly connected with the same connecting plate, a vertical rod is fixedly connected to the bottom of the ejector rod, and the bottom of the vertical rod is fixedly connected with the connecting plate. The lifting tray is controlled to descend, the lower positioning block is clamped into the clamping groove in the upper positioning block, the position of the lifting tray is locked, and then the problem that a chain is damaged after a long time due to the fact that a traditional refueling ladder trailer mode mainly depends on ascending and descending of the chain of the refueling ladder is solved through driving of the two air cylinders.

    本发明涉及气动提升装置技术领域,且公开了一种具有稳定结构的气动提升装置,包括固定架和提升托盘,所述固定架包括顶杆,所述顶杆的底部固定连接有固定框,所述固定框的两端分别固定连接有安装耳,所述固定框内侧壁开设有提升槽,所述顶杆的底部固定连接有两个气缸,两个所述气缸的底部分别固定连接有同一个连接板,所述顶杆的底部固定连接有竖杆,所述竖杆的底部与连接板固定连接。制提升托盘下降,使下定位块卡进上定位块上的卡槽内,锁定提升托盘的位置,进而通过两个气缸的驱动解决了传统的加油梯挂车方式主要依靠加油梯自身链条上升下降,时间长了会对链条造成损伤的问题。
