Rope loosening overload protection device for heavy stacking robot

The invention relates to the technical field of storage equipment, and discloses a rope loosening overload protection device for a heavy stacking robot, and the rope loosening overload device is mounted on the side edge of a cargo carrying table, so that the cargo carrying table can drive the rope loosening overload device to synchronously move when moving up and down; according to the rope loosening overload device, the rope loosening overload device can be moved to the bottommost portion to conduct convenient, fast and safe adjustment when an operator needs to conduct installation, maintenance, initial deformation quantity setting and effective stroke setting on the rope loosening overload device, meanwhile, a rope wheel capable of moving relative to a cargo carrying table is arranged in the rope loosening overload device, and when the cargo carrying table is overweight, the rope wheel can move relative to the cargo carrying table. When the rope is loosened and overloaded, the disc spring is pressed downwar
