A chain plate type conveyor of an iron making department of Spanish mackerel ring division company of Anemarrhena strand is directly used for bearing sinter discharged by ring cooling, and has the advantages of high temperature, heavy load, more small particles and dust and severe operation environment. The chain plate shaft of the chain plate type conveyor consists of a roller, a sleeve and a pin shaft, small particles easily enter between the pin shaft and the shaft sleeve, and a sliding gap between the shaft sleeve and the pin shaft is ground, so that an outer chain plate and the shaft rotate to cause the abrasion of the chain plate, the shaft hole is enlarged, the abrasion of a driving chain wheel is aggravated, and even the chain shaft is broken. If the large sintered material is clamped between the inner chain plate and the outer chain plate, the split pin on the shaft head is easy to cut off, and the machine needs to be stopped for 6 hours to replace the pin shaft. Because the condition of shutdown replacement is not provided at ordinary times, the replacement can be carried out only in fixed maintenance, shutdown accidents are easy to form, and the shutdown of the chain plate type conveyor can cause the shutdown of the sintering machine until the reduction of the production of the blast furnace or even the damping down is caused.
Disclosure of Invention
