Gas cylinder transfer device

The utility model relates to the technical field of pressure vessel transfer, in particular to a gas cylinder transfer device which comprises a loading frame and a movable frame arranged on the loading frame, the loading frame comprises a loading cavity defined by a bottom plate and side plates, the upper portion of the loading cavity is open, walking wheels for the transfer device to move are arranged below the bottom plate, and the movable frame comprises a blocking frame and a supporting mechanism. One end of the supporting mechanism is connected with the side plate, and the other end of the supporting mechanism is connected with the blocking frame. According to the gas cylinder transfer device, the liftable movable frame is arranged at the top of the loading cavity, so that the gas cylinders which are vertically placed and have different length specifications can be adapted by means of the height-variable blocking frame, and the problems that the height of a side plate of a traditional car hopper is small
