Abstract

The invention relates to the field of vehicle repair and rescue, and discloses a pneumatic hoisting device. The device is characterized by comprising an upper shell and a lower shell, wherein side walls of the upper shell and the lower shell are in sliding fit with each other along the vertical direction; an air bag is placed in a cavity formed by the upper shell and the lower shell; and the air bag is provided with an air nozzle which is extended out of the lower shell. The device has the advantages of simple structure, light weight, convenient carrying, rational design, simple operation, convenient use; and the device can bear large pressure, can be used under the condition of uneven mellowness and narrow space and does not need special operation space.

Description

technical field [0001] The invention relates to the field of vehicle maintenance and lifesaving rescue, in particular to a pneumatic lifting device. Background technique [0002] At present, jacks are generally used for lifting in vehicle maintenance or lifesaving rescue. General-purpose jacks are generally steel hydraulic structures. Jacks used for large vehicles are often heavy and difficult to implement; and when using jacks, a certain amount of operating space is required, and the jack must be placed on a flat and hard ground or The road surface, especially if the road surface or ground is sloped, uneven or soft, cannot be used at all. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a pneumatic lifting device with simple structure, convenient use and reasonable design, which is light in weight and easy to carry, and can be used in the case of looseness, unevenness and nar...
