A novel method for operating a discharging platform comprises the following steps: Step 1: Install the guide wheel type attachment support (11) and the electric hoist lifting bracket (12) at the corresponding position of the layer to be loaded; Step 2: Assemble the car bottom frame assembly (51) on the ground by bolts and pins, combine the car bottom frame assembly (51) with the car bottom plate assembly (52) by bolts, connect the car side protection assembly (53) with the car bottom frame assembly (51) by bolts, connect and fix the end frame assembly (55) with the car bottom frame assembly (51), the car bottom plate assembly (52) and the car side protection assembly (53) respectively by bolts, install the unloading platform flap assembly (54) on the surface of the car bottom plate assembly (52) in the center by self-tapping screws and flap hinges, and fasten the protection plate (56), the side tie plate (57) and the car side protection assembly (53) with bolts after aligning the holes, wherein the side tie plate (57) will be fastened with the guide rail (21) by bolts later; Step 3: Assemble the bottom operating platform (3), fasten the walkway board (31) of corresponding size with the walkway connecting plate (32) and bolts, then install the bottom operating platform guardrail (34), the bottom of the bottom operating platform guardrail (34) is bolted to the walkway board (31), and finally install the bottom operating platform siderail (33), the bottom of the bottom operating platform siderail (33) is bolted to the walkway board (31), and the two sets of bottom operating platform siderails (33) are respectively fastened to the two ends of the bottom operating platform guardrail (34) with bolts; Step 4: Place a number of wooden blocks on the ground, place four sets of guide rails (21) horizontally in pairs and connect them in a normal manner, and use guide rail inner plug-ins (22) and material platform guide rail connectors (23) to fasten them with bolts; install a set of material platform guide rail trusses (24) between two sets of guide rails (21) at the same height, use bolts to install two sets of material platform upper hanging points (25) at corresponding positions of one set of material platform guide rail trusses (24), use high-strength bolts to install two sets of material platform lower hanging points (26) at corresponding positions of the other set of material platform guide rail trusses (24), and install an inverted electric hoist (27) on the same side material platform hanging points (25) and material platform lower hanging points (26) in a conventional manner. After installation and adjustment, the chain is in a relaxed state, and the chain is tied at intervals, and the unloading platform vertical surface protection component (6) is installed with bolts below the material platform guide rail trusses (24) at the top; Step 5: On flat ground, pass the lifting belt through the lifting hole of the car body (5), slowly lift it up and place it on the guide rail (21), adjust the position, use bolts to fasten the two sets of side tie plates (57) to the corresponding guide rails (21), fasten the walkway plate (31) of the bottom operating platform (3) to the guide rail (21) on flat ground with bolts, and fasten the side rails (33) of the bottom operating platform to the material platform guide rail truss (24) with bolts; Step 6: Connect one end of the two groups of large diagonal braces (42) and the two groups of small diagonal braces (44) to the main beam of the car bottom frame assembly (51) by using a pin shaft, connect the other end of the two groups of large diagonal braces (42) and the two groups of small diagonal braces (44) to the diagonal brace support (41) by using a pin shaft, install the diagonal brace support (41) and the guide rail (21) by bolts, use the conventional installation method for the steel pipe diagonal rod (43), connect the diagonal brace support (41) and the main beam of the car bottom frame assembly (51) in turn, slowly lift the assembled unloading platform from the ground, and place it at the position of the guide wheel type attachment support (11) of the installation layer for assembly.
