[0002] The general layout form of the bunker top platform is as Figure 1 shown. A belt conveyor 2 and a discharging truck 1 are arranged on the bunker top platform. A discharging truck track 3 is arranged outside the discharge opening, and a load-bearing steel beam 5 is arranged directly below the track. The material flow 4 is directed towards the load-bearing beam. Materials such as coke and lump ore have relatively sharp edges and corners, and the material flow direction will cause certain impact and friction on the load-bearing beam.

[0003] When the load-bearing beam at the discharge opening of the bunker is a steel structure beam, the material not only causes impact and friction on the load-bearing steel beam, but also has strong corrosiveness. After a long time, the web and flange of the load-bearing steel beam may be damaged, which affects the structural safety of the bunker. Therefore, the load-bearing steel beam needs to be protected.

[0004] Currently, the common protection methods are as follows:

[0005] 1. Spraying high-strength wear-resistant material. Before spraying, anchor claws need to be welded. For an already put-into-use bunker, the construction is troublesome and the construction measure cost is relatively high.

[0006] 2. Lining ceramic plates at the protection position. It is heavy, increases the burden on the load-bearing steel beam, has a large construction workload, a long construction time at high altitude, and the price of the lining plates is relatively high.

[0007] 3. Adding various metal lining plates at the protection position. Bolts need to be welded on the protection position of the steel beam, and the lining plates are connected by bolts. The construction workload is large, the construction time at high altitude is long, and the bolt holes may be deformed due to temperature changes, and it is easy to fall off.
