The invention discloses a device for quickly lifting heavy objects. The device comprises an oblique surface, a bottom surface, a supporting rod, a transmission device, a conveying device and a drive device, wherein the bottom edge of the oblique surface is connected with one side edge of the bottom surface through a hinge, and the top edge of the oblique surface and the other side edge of the bottom surface are supported and fixed by the supporting rod; the transmission device is arranged above the oblique surface along the oblique surface and in drive connection with the drive device; the conveying device is put on the oblique surface and is in transmission connection with the transmission device. When the conveying device moves upwards and is contacted with a normally-open switch, a trolley changes the moving direction and moves downwards; when the conveying device moves downwards and is contacted with a pause switch, the trolley stops moving. The device with a motor with power of 24 w can bear at least 24 kg of the heavy objects, the energy efficiency ratio is high, meanwhile, the heavy objects are ascended or descended for 300 mm only in about 7 seconds, and the speed is very high.
