The invention discloses an aluminum plate carrying device. The aluminum plate carrying device comprises a base. The bottom of the base is provided with a walking mechanism. The upper surface of the base is provided with a vertical column and an inclined guide rail. A groove is formed in the guide rail. A screw rod is arranged in the groove. The aluminum plate carrying device further comprises a carrying plate which is arranged horizontally, a sliding block and a power source. The carrying plate is fixedly connected with the sliding block. The sliding block is slidably connected with the guide rail. The bottom of the sliding block is further provided with a nut. The nut is matched with the screw rod. The power source is fixed to the top of the vertical column and is used for driving the screw rod to rotate. The carrying plate is further provided with a material pushing mechanism and an assistant supporting mechanism. The material pushing mechanism is used for pushing an aluminum plate to slide. The assistant supporting mechanism is used for supporting the aluminum plate. According to the aluminum plate carrying device, the conveying and transporting process of the aluminum plate is more convenient, faster and simpler, the entire structural stability is good, after the carrying plate reaches the designated position, the aluminum plate on the assistant supporting mechanism is pushed by the material pushing mechanism to be unloaded, the discharging process of the aluminum plate is safer and more convenient, and meanwhile the device is further convenient to move.
