Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sintering trolleys, and specifically relates to wear-resistant and anti-falling grate bars of a sintering trolley. Background Art
[0002] The grate bar is the main accessory on the sintering machine trolley. The two ends of the upper part of the grate bar are subjected to force and play a supporting role. After repeated cycles of heating, cooling, impact, and wear, the grate bar is gradually oxidized, worn, deformed, and damaged.
[0003] Grate bars are a key component that plays an important role in industrial production. The working conditions of grate bars are harsh and the causes of their damage are complex. They are vulnerable parts. During the loading and unloading process, the grate bars need to withstand the impact and friction and wear of the sintered ore. Once the grate bars cannot withstand the impact and break and fall, the material will fall through the gap, thus affecting the processing of the material. Although the existing grate bars can carry the material, there is no connection between the multiple grate bars, so that the impact borne by a single grate bar cannot be dispersed, and the structure of a single grate bar is not stable enough, so it needs to be improved.

[0025] The bottom of the upper clamping plate 1 is fixedly mounted with a side plate 10 , the inner part of the side plate 10 is movably sleeved with a movable shaft 11 , and the outer surface of the movable shaft 11 is fixedly sleeved with a lower clamping plate 12 .

[0027] A cavity 13 is formed inside the lower clamping plate 12 , and a first gear 14 located inside the cavity 13 is fixedly sleeved on the outer surface of the movable shaft 11 .
