[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figures 1-6 As shown, a building component unloading device includes an unloading platform 1. A rotating shaft 6 is rotatably mounted on the top right end of the unloading platform 1. Winching rollers 7 are coaxially fixed at both the front and rear ends of the rotating shaft 6. Chain ropes 8 are wound inside the two winching rollers 7. A pedal 9 is provided on the right end of the unloading platform 1. The outer surface of the left end of the pedal 9 is rotatably connected to the bottom right end of the inner wall of the unloading platform 1 by a pin. Locking holes 12 are opened on the right ends of both the front and back sides of the pedal 9. Pin sleeves 14 are fixedly welded to the top right ends of the outer surfaces of both the front and back sides of the unloading platform 1. Locking pins 16 are slidably mounted inside the pin sleeves 14.

[0023] The top right side of both sides of the unloading platform 1 is fixedly welded with a support platform 2. The left side of the top surface of the support platform 2 on the front side is fixedly installed with a DC motor 3 by bolts. The right side of the DC motor 3 is provided with a transmission box 4. The bottom of the transmission box 4 is fixedly connected to the support platform 2 by bolts.
