When the chain scraper conveyor stopped no-load operation, there was no abnormality. With the increase of weight, the chain scraper conveyor shows the state of the tail chain chain jumping and shaking. For this problem, we make the following analysis.
The tension on the tail wheel of the chain scraper 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 is gradually increased to restart the feed of the roller press. About 50% of the time, the starting end showed the phenomenon of a tail wheel chain ratchet, and a tensioned connecting rod was bent and deformed, and the pin at the fulcrum was also destroyed. According to the analysis, after the weight is increased, the impact load on the tensioning device is also increased due to the vibration of the tail chain, and the deformation of the connecting rod and the fracture of the pin are formed, 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 chain scraper conveyor. The technician then re-examines the extent of the head axle to the standard 0.3 mm / m; checks the parallelism of the head and tail sprocket of the wire. Check the tooth pitch of the tail tooth and the pitch deviation of the chain.
The reasons for 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.
