Abstract
The utility model relates to the technical field of cargo lifting devices, and discloses a safe cargo lifting device for building construction, which comprises a support rail column, a transport car, a support plate, a mounting seat, a limiting seat and a limiting guide roller, the periphery of the limiting guide roller is in limiting rolling fit with the outside of the support rail column through a limiting rail groove, and a storage groove is formed in the inner side of the limiting rail groove. When the transportation car stalls and falls down, the limiting guide rollers are driven by the transportation car to be located outside the supporting rail columns to be in a high-speed rotating state, at the moment, the multiple sets of locking hooks in the containing groove can be thrown out under the rotating centrifugal force, and the limiting guide rollers can be driven by the limiting guide rollers to be located outside the supporting rail columns to be in a high-speed rotating state. And when the locking hook is thrown out to be in hanging buckle clamping connection with the fixing rod in the rectangular groove, the locking hook can rapidly lock and brake the storage groove, the transportation lift car stops falling, and therefore the effects that when the transportation lift car stalls, locking limiting protection can be automatically conducted, and more dangerous conditions are avoided are achieved.
