The invention discloses a discharging platform with an overload alarm function. The discharging platform comprises an attachment device, a climbing device, a main bearing frame, a track, a platform beam and a vertical ladder, and further comprises an overload alarm system consisting of an overload alarm platform, a warning device and a display screen, and the overload alarm system can climb mutually with the main bearing frame through the track to realize autonomous climbing with the floor height below 7 m. The overload alarm system has the functions of load real-time display and overload alarm, and data can be in butt joint with a project intelligent construction site platform and monitoring software. The discharging platform has the functions of self-climbing, overload alarm and data transmission, the weight of materials can be displayed in real time, an alarm threshold value can be preset, an acousto-optic alarm can be given through a warning device when the alarm threshold value is reached, the overload phenomenon is avoided, the construction safety is guaranteed, meanwhile a tool type and modular design is designed, compared with a traditional discharging platform, the discharging platform is scientific in structure and is convenient to assemble and disassemble, and the intelligent degree is greatly improved.
