The sprocket shaft set is one of the important components of the coal mining scraper conveyor. With the extension of the equipment running time, the sprocket shaft set will also experience varying degrees of wear. When its degree of wear reaches a certain limit, it must be replaced. If it continues to be used, it will inevitably cause more serious consequences to the coal mining scraper conveyor.
Before replacing the sprocket shaft set of the coal mining scraper conveyor, the materials on the transporter and the transfer machine must be emptied, so that the scraper is connected in a pair of links to near the sprocket of the nose, and the three machines must be locked and locked; Notify 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 tensioning cylinder control valve at the tail of the coal mining scraper conveyor, take out the positioning pins on both sides of the tensioning part, and retract the tensioning jack to loosen the chain of the coal mining 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 go around the disassembled chain.
In addition to the wear of the sprocket shaft group due to the use of the coal mining scraper conveyor, the chain is also the same, and even breakage. Preventing the chain of the coal mining scraper conveyor from breaking is the key to ensuring the normal production of the equipment, so not only must the chain of the coal mining scraper conveyor maintain proper tension, but also balance the distance between the two sides of the chain of the coal mining scraper conveyor to ensure that the chain is not overloaded.
When using the coal mining scraper conveyor, it must be in accordance with its standard load to ensure the dynamic tension of the motor when the load starts to protect the chain. In addition, aligning the chute of the coal mining scraper conveyor, checking the chain links of the scraper regularly, and replacing the deformed and worn chains in time are all good to prevent the chain from breaking.
