When the chain scraper conveyor stopped running without load, there was no abnormality. As the weight increases, the chain scraper conveyor assumes that the tail chain jumps and shakes. For this problem, we make the following analysis:
The tension of the tail wheel of the scraper chain conveyor is insufficient. The tension of the tail wheel of the traction machine is stopped by the lever suspension weight, so the weight is increased to the tensioning device of the tail wheel, and the roller press gradually increases to restart the feeding of the roller press. At about 50% of the time, the starting end showed the phenomenon of the ratchet of the tail wheel chain, and a tension link was formed to flex and deform, and the pin at the fulcrum was also broken. According to the analysis, after the weight is increased, due to the vibration of the tail chain, the impact load on the tensioner also increases, and the deformation of the connecting rod and the breakage of the pin form, thereby eliminating the amount of cleaning and lifting. Large, long chain life.
There is a problem with the alignment of the head and tail wheels of the scraper chain conveyor. Then, the technician re-checks the degree of the head shaft to make it reach the standard 0.3 mm / m; check the parallelism of the wire head and tail sprocket. Check the pitch deviation of the tail teeth and the pitch deviation of the chain.
The cause of the chain jumper of the chain scraper conveyor can be stopped from the above three aspects, and the tail wheel adjustment should be done to prevent the equipment from running normally.
