The invention discloses a protection device for safety technology precaution construction, and relates to the technical field of protection devices for construction. The trolley comprises a trolley body and a handlebar and further comprises lifting devices, the lifting devices are arranged on the two sides of the top face of the trolley body, each lifting device comprises two servo motors, two threaded rods, two long plates, two U-shaped sliding rods, a goods storage box, four cylinders and four round pads, the two servo motors are fixed to the two sides of the top face of the trolley body respectively, and the two long plates are fixed to the two sides of the top face of the trolley body respectively. The two threaded rods are fixed to the top faces of the two servo motors correspondingly, the two long plates are rotationally installed at the bottoms of the outer walls of the two threaded rods correspondingly, internal threads of the two long plates are meshed with threads of the two threaded rods, and the two U-shaped sliding rods are fixed to the two sides of the top face of the trolley correspondingly. The two long plates are installed on the inner walls of the two U-shaped sliding rods in a sliding mode correspondingly. The long plate supports the cargo storage box, so that the protective device is prevented from lifting cargos and crashing the cargos.
