[0002] The unloading platform is a temporary operating table and operating frame often set up at the construction site. It can be used for various masonry, decoration and painting operations. Especially in the construction of high-rise buildings, the use of unloading platforms can effectively solve the problem of vertical transportation of materials.

[0003] Based on the above, the inventors found that: in actual use, as the height of the building floors continues to increase, it is necessary to continuously transfer the position of the unloading platform according to the floor height of the construction building to match the current construction floor. However, in the process of transferring, the existing cantilever unloading platform needs to first release the fixation between the cantilever beam and the structural floor, and release the connection between the wire rope and the upper outer wall, and then lift it to the height of one floor through the tower crane, and then fix the cantilever beam and the structural floor in turn, and complete the connection between the wire rope and the upper outer wall. The operation is very inconvenient, and the transfer efficiency and stability of the unloading platform are low. At the same time, when unloading, staff are usually required to stand on the unloading platform and move the materials down one by one. Due to the limited space of the unloading platform, the handling operation is restricted and it is not convenient to use. Therefore, in view of this, the present invention studies and improves the existing structure, and provides a new self-climbing unloading platform and its application method, in order to achieve the purpose of more practical value.
