Sprocket components and scraper chain as the important transmission configuration of scraper conveyor, if there is a fault, it may affect the normal operation of underground coal mining work. So how do you deal with such situations? The sprocket components sometimes has the phenomenon of high temperature in the operation process, the cause may be the insufficient lubricating oil, or the damage of bearing and sprocket may cause the aggravation of friction, which makes the temperature rise. Then the solution is to oil the sprocket assembly, so that the amount of oil to the specified requirements, or replace the worn bearing, sprocket body to make a new replacement. The scraper chain has the condition of jumping teeth at the sprocket assembly, which is caused by many factors, such as too loose scraper chain, twisted chain segment, unequal length or elongation of double-strand chain or different number of rings, as well as the influence of excessive scraper deformation. The correct treatment method is to adjust it: re-tensioning the scraper chain, re-install the twisted chain segment correctly, check the scraper chain length and elongation if unqualified, it should be adjusted and replaced, and must use the odd ring chain, and is to replace the seriously deformed scraper. Inspect the daily maintenance of sprocket assembly and chain of scraper conveyer according to different conditions, deal with and solve the faults in time, reduce the influence of associated problems.

The dumbbell pin plays an important role in the normal operation of the scraper conveyer as the connecting member between two adjacent chutes. Today the coal machine parts manufacturer Henan shuanzhi will introduce the dumbbell pin of scraper conveyer for you. Scraper conveyor dumbbell pin shape is like "fitness dumbbell", the middle is thinner, thicker at both ends. The dumbbell pin jams the ends of the two adjacent middle slots by the thicker ends at each end and connects the two adjacent middle slots by the thin middle rod. In addition to the common dumbbell pins described above, there are two types of special shaped dumbbell pins - I-type dumbbell pins and day-type rings. The stress condition of dumbbell pin is more complicated. In the process of hydraulic support moving the middle trough, the dumbbell pin will be pulled by the adjacent middle trough and subjected to shear stress because the adjacent chute is not synchronized. The dumbbell pin of scraper conveyor is a vulnerable part, and the common fault is fracture. The first crack occurred in the neck of the dumbbell pin, mainly because the neck of the dumbbell pin is a region where stress concentration is relatively large. Under long-term working conditions, the dumbbell pin's neck crack growth area diffused to a certain extent, resulting in fatigue fracture, resulting in the fracture of the whole dumbbell pin. Once the dumbbell pin is broken, it will cause the middle slot dislocation or off, the scraper chain is affected by it, easy to break the chain, the chain clip, from the chute off the phenomenon, affecting the scraper conveyor working surface production safety and normal production. Above is the dumbbell pin on the scraper conveyer, do you know? The dumbbell pin of the scraper conveyer produced by Henan Shuangzhi is forged from the selected material of 40Cr, and the quality is comparable to that of the original products after multiple processes such as tempering and quenching.

Reducer has the characteristics of large bearing capacity, high transmission efficiency, generally used for input shaft and output shaft are arranged in a vertical direction of the transmission device. For the coal mine scraper reducer oil leakage of the reasons are usually only two points: sealing ring damage and the box body joint surface is not strict. Most of the oil leakage of the scraper reducer is caused by the damage of the sealing ring. After long-term operation and the influence of underground coal mine environment, the sealing ring will inevitably wear down, resulting in poor sealing effect and oil leakage. However, it can be well solved by simply replacing the sealing ring. For the box body joint surface lax than the former slightly less, this situation is mostly the upper and lower box body lax, the end pressure cap is not tight, may be caused by the assembly irregularities, may also be caused by the long-term operation of bolts loose, the solution is to tighten all parts of the bolts.
