The invention discloses iron nail attracting equipment for building construction protection. The iron nail attracting equipment for the building construction protection structurally comprises an ironnail attracting main machine, a switch, a handle, an energization device, moving wheels and heat dissipation holes, the switch is embedded on the outer surface of the iron nail attracting main machineand is electrically connected with the outer surface of the iron nail attracting main machine through a guide wire, the handle is arranged at the top end of the iron nail attracting main machine, theenergization device is fixedly mounted on the iron nail attracting main machine and is electrically connected with the iron nail attracting main machine through the guide wire, and the four moving wheels are fixedly mounted at four corners of the bottom of the iron nail attracting main machine. The heat dissipation holes are embedded at the bottom end of the iron nail attracting main machine, iron nails are automatically attracted through the decreasing of a lifting iron attracting mechanism, the rising of the lifting iron attracting mechanism can enable an automatic energization and deenergization mechanism to deenergize automatically, so that the iron nails automatically drop on a placing mechanism, the iron nails on an electromagnetic chuck can be automatically taken out for processingin the midway, the electromagnetic chuck is prevented from being fully attracted with the iron nails, magnetism of the electromagnetic chuck is reduced, and parts of the iron nails are prevented frombeing attracted; and meanwhile, the iron nail release collection work after the automatic iron nail attracting is realized, the working amount of workers is reduced, and the using is more convenient.
