Beschreibung
Zusammenfassung:	The invention discloses a lifting device. The lifting device comprises a ball screw, a lead screw nut, a lifting transmission device and an anti-explosion mechanism. The lead screw nut is installed on the ball screw. The lifting transmission device comprises a lifting support, a lifting motor and a transmission pair, the lifting motor is arranged on the lifting support, the lifting motor is in meshed connection with the transmission pair, the transmission pair is in transmission connection with the lead screw nut, and the lifting support enables the lifting transmission device and the lead screw nut to be connected into a whole through the transmission pair. The anti-explosion mechanism is arranged between the transmission pair and the ball screw. According to the lifting device, the lifting motor drives the transmission pair to rotate, the transmission pair drives the integrity of the lifting transmission device and the lead screw nut to move in the length direction of the ball screw, and therefore the phenomenon that a ball falls into a die after being broken or exploded is avoided; meanwhile, the anti-explosion mechanism is locked on the ball screw, so the integrity of the lifting transmission device and the lead screw nut is prevented from moving on the ball screw, workers are prevented from being hurt, and meanwhile damage to equipment or other parts is avoided.
