The sprocket shaft set is one of the important components of the chain scraper conveyor. When the chain scraper conveyor has been running for a long time, its sprocket shaft set will also experience varying degrees of wear. When its degree of wear reaches a certain limit, if it continues to be used, it will inevitably cause more serious consequences to the chain scraper conveyor, so it must be replaced in time.
Before replacing the sprocket shaft set of the scraper chain conveyor, the materials on the conveyor and the transfer machine must be emptied, so that the chain scraper conveyor is connected in pairs and connected to the vicinity of the sprocket near the head, and the three machines must be locked and locked. ; Then control the console to turn the handle of the power isolation switch of the three machines to the off position and lock it.
Next is to operate the tension cylinder control valve at the tail of the chain scraper conveyor, take out the positioning pins on both sides of the tension part, and retract the tension jack to loosen the chain of the chain scraper conveyor. Then take out the rising pin of the link link with a hand hammer and a punch, and disassemble the link link; then fix the chain hoist on the lifting link of the top beam of the support, and use the chain hoist to bypass the disassembled chain.
In addition to the wear of the sprocket shaft assembly due to the use of the scraper chain conveyor, the chain is also the same, and even breakage. In order to prevent the chain from being damaged, it is necessary not only to maintain the proper tension of the chain of the chain scraper conveyor, but also to balance the distance between the two sides of the chain of the scraper conveyor to ensure that the chain is not overloaded.
When using the scraper chain conveyor, it must be in accordance with its standard load to ensure the dynamic tension of the motor when the load starts, so as to protect the chain. In addition, aligning the chute of the chain scraper conveyor, regularly checking the chain links of the scraper, and timely replacement of deformed and worn chains are good for preventing chain breakage.
