[0022] Compared with the prior art, the intelligent material lifting device and construction method of the building construction platform have the following beneficial effects:

[0023] 1. The present invention uses a lifting component and a maintenance and protection component, so that the material is protected by the maintenance and protection component during the lifting process and is not easily damaged, thereby improving the stability and efficiency of the lifting process. The maintenance and protection component can effectively protect the material, avoid the occurrence of dangerous situations during the lifting process, and avoid safety hazards.

Subsequently, the electric push rod drives the limit plate to move upward, and the limit plate is separated from the support plate. Under the action of the telescopic rod and the spring, the support plate retracts to the movable bin to avoid affecting the closure of the fixed plate. At the same time, the limit plate can be clamped in the second limit groove on the surface of the material basket to limit the material basket and avoid deviation of the material basket during lifting, which causes the material basket to move in the protective groove, thereby improving the safety of the device.

[0025] 3. The present invention can protect the material basket on the protection trough through the fixing unit. It can not only effectively isolate the lifting area when the material basket is placed on the ground to prevent people or other objects from accidentally entering the operating area of ​​the lifting component, thereby improving the safety of the workplace, but also avoid the splashing of materials during the lifting process, and prevent the materials from falling from a height to pollute the working environment below or cause harm to the staff, thereby ensuring the stable operation of the production process and improving production efficiency.
