Abstract

The invention discloses a liquid nitrogen dumping device and a dumping method thereof. The dumping device comprises a rack, a driving mechanism, a rotating shaft, a liquid nitrogen tank hoop locking mechanism and a liquid nitrogen funnel; a driving mechanism mounting platform and a rotating shaft supporting frame are arranged on the rack; the rotating shaft is mounted on the rotating shaft supporting frame; the driving mechanism is mounted on the driving mechanism mounting platform; the driving mechanism drives the rotating shaft to rotate; the upper end of the liquid nitrogen tank hoop locking mechanism is fixedly connected to the rotating shaft; and the liquid nitrogen funnel is installed on the rack, and when the driving mechanism drives the rotating shaft to rotate, the rotating shaft drives the liquid nitrogen tank hoop locking mechanism to rotate, so that a necking opening in the upper end of the liquid nitrogen tank hoop locking mechanism corresponds to the liquid nitrogen funnel. According to the liquid nitrogen dumping device, rapid clamping of a liquid nitrogen bottle can be achieved through the dumping device, liquid nitrogen is automatically and stably poured into a liquid nitrogen container, and the method is easy to operate, high in reliability, high in applicability and free of potential safety hazards.

Description

technical field [0001] The invention belongs to the field of liquid nitrogen cooling assembly for armored vehicles, and in particular relates to a liquid nitrogen dumping device and a dumping method thereof. Background technique [0002] Since the guide device of the armored vehicle suspension system is assembled with an interference fit with the steering knuckle, the guide device needs to be cooled with liquid nitrogen before assembly, so that the guide device can be cooled and shrunk before the assembly can be completed. Liquid nitrogen is a colorless liquid that is stored in a pressure-resistant steel cylinder. When cooling the guide device, it is necessary to pour the liquid nitrogen in the liquid nitrogen bottle into the liquid nitrogen bucket first, and then put the guide device into the liquid nitrogen bucket to cool. During the process of pouring liquid nitrogen, the liquid nitrogen will absorb a lot of heat when it vaporizes, and skin contact will cause frostbite. ...
