Engine cylinder sleeve liquid nitrogen cooling treatment equipment

The invention relates to treatment equipment, in particular to engine cylinder sleeve liquid nitrogen cooling treatment equipment. According to the engine cylinder sleeve liquid nitrogen cooling treatment equipment, a cylinder sleeve can be automatically put in and taken out, and hands can be prevented from being frostbitten. The engine cylinder sleeve liquid nitrogen cooling treatment equipment comprises a base, a driving mechanism and a lifting platform. A liquid nitrogen barrel is connected to the base. The driving mechanism is arranged between the base and the liquid nitrogen barrel. The lifting platform is arranged on the liquid nitrogen barrel, and the lifting platform is in transmission connection with the driving mechanism. According to the equipment, the driving mechanism can drive the lifting platform to work, the lifting platform works so that the cylinder sleeve can move downwards to enter liquid nitrogen in the liquid nitrogen barrel to be cooled, the cooled cylinder sleeve can move upwards to mo
