The chain scraper conveyor has coal on the chain, and the lower chain is hidden. If the chain is interrupted during operation, it is not easy to find, and it can only be judged from the symptoms. When the chain scraper conveyor is running, the scraper chain suddenly sags or accumulates under the machine head or the side of the double chain scraper conveyor is suddenly skewed during operation, indicating that the chain is broken.
The reasons for the broken chain of the chain scraper conveyor are: ① overloading the coal too much and pressing the scraper chain; ② the working surface is not straight and flat, especially the curved curved working surface, and the outer chain of the side double chain is overloaded Large, it is the easiest to be broken; ③ The friction between the chain and the middle groove and the sprocket for a long time will reduce the wear and deformation section and reduce the strength; ④ In addition to the average load, the chain will also transmit the dynamic load of the sprocket in use. The chain is subjected to dynamic loading for a long time, causing fatigue damage, increasing pitch, and reducing strength; ⑤ The quality of the chain itself is poor.
