The invention discloses a pneumatic lifting device. The pneumatic lifting device comprises a lifting platform, air bag type air cylinders, guiding rods, wear-resistant copper sleeves, lifting protection devices, pin shafts, limiting blocks for the guiding rods and a fixing frame, wherein the upper surface of the lifting platform is directly in contact with a carried weight; the upper surfaces of the air bag type air cylinders are fixedly connected with the lower bottom surface of the lifting platform; the lower surfaces of the air bag type air cylinders are fixedly connected with the upper part of the fixing frame; the wear-resistant copper sleeves are fixed at the upper part of the fixing frame; after penetrating through the wear-resistant copper sleeves, the top ends of the guiding rods are fixedly connected with a fixing sleeve on the lower bottom surface of the lifting platform; the limiting blocks for the guiding rods are fixed at the bottoms of the corresponding guiding rods separately; when a main air channel supplies air to the air bag type air cylinders (1), the air bag type air cylinders are inflated and expand, so that the lifting platform and the guiding rods are pushed to move together upwards along the inner sides of the wear-resisting copper sleeves (4). According to the pneumatic lifting device disclosed by the invention, the air bag type air cylinders which are high in capability of bearing axial loads and radial loads are adopted so that the flexible transmission of bearing force, effective stroke adjustment and high-efficiency control over the vibration can be realized, and the safety of the whole lifting and transporting process is guaranteed.
