The utility model has a simple structure and a novel design. The grate bars are redesigned and the original three grate bars are arranged in one body, which strengthens the firm connection between the grate bars and increases the mutual force between the middle beams. The vertical dimension of the middle grate bar of the three integrated grate bars is reduced, which reduces the installed weight of the grate bars of each trolley, reduces the total weight of the trolley, reduces the operating load, and makes the high-temperature wind from the grate bars to the bottom smoother, which can effectively prevent the deformation of the guide ribs and the breakage and falling off of the middle beam.

[0004] Although the grate bars in the prior art can reduce the vertical dimension of the grate bars, reduce the installed weight of the grate bars on each trolley, reduce the total weight of the trolley, reduce the operating load, and the high-temperature wind from the grate bars to the bottom is more unobstructed, which can effectively prevent the deformation of the guide ribs and the breakage and falling of the center beam, there is a problem of insufficient concentrated strength, and the single-layer structure is prone to insufficient local force. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a high temperature resistant grate bar.

[0006] The utility model is implemented by the following technical scheme: a high-temperature resistant grate bar is provided with a grate bar, the grate bar is divided into an upper grate bar and a lower grate bar, a heat dissipation space is provided between the upper grate bar and the lower grate bar, a supporting column is provided in the heat dissipation space, the supporting column and the upper grate bar and the lower grate bar are welded and connected, a heat dissipation gap is provided on the grate bar, the heat dissipation gap is flatly arranged on the grate bar, the heat dissipation gap adopts a long strip heat dissipation gap, an assembly set is provided on the outer side of the grate bar, an assembly space is provided inside the assembly set, a side shelf is provided in the assembly space, and the grate bar is fixed in the assembly set by the side shelf.

[0007] The bottom of the assembly sleeve is provided with a circular heat dissipation hole, the top of the circular heat dissipation hole is provided with a grate bar, and the outer side of the assembly sleeve is provided with an assembly component.
