The invention relates to a pneumatic lifting device and belongs to the technical field of hoisting equipment. The device comprises a lower frame, an upper frame, a first movable bracket, a second movable bracket, a third movable bracket, a fourth movable bracket and an air cylinder. According to the technical scheme, the third movable bracket is pushed by the air cylinder and slides along the fourth movable bracket, and the first movable bracket and the second movable bracket are overlapped gradually, so that the upper frame is lowered; when the upper frame rises, the air cylinder drives a telescopic rod to telescope to recover the unfolded state of the third movable bracket and the fourth movable bracket, the lifting device is lowered when the air cylinder completely unfolds, the control on downward transportation of cargos is improved, and the device has the beneficial technical effects and significant practical value.
Description
technical field [0001] The invention relates to a pneumatic lifting device, which belongs to the technical field of lifting equipment. Background technique [0002] The lifting platform is a multi-functional lifting and loading mechanical equipment, which can be divided into fixed type and mobile type, guide rail type, and crank arm type. The fixed type includes scissor lifts, chain lifts, loading and unloading platforms and attached electric construction platforms. Wait. Lifting platform is a kind of hoisting machinery that transports people or objects vertically. The general lifting platform adopts hydraulic drive or pneumatic drive, which is not only used for cargo transfer and lifting, but also widely used in high-altitude installation, maintenance and other operations. Most of the existing lifting platforms use oil cylinders or air cylinders to push the lifting platform to perform lifting operations. It is convenient and fast when the goods need to be transported upwa...
