In daily life, it is necessary to perform certain maintenance on the coal mining scraper conveyor, otherwise it will bring more losses than necessary. The collective maintenance is described below.
During the operation of coal mining scraper conveyor, pay attention to check the tightness of the scraper chain. The connection between the chute will reduce the distance due to the operation. If the chain is too loose, there will be accidents such as jamming, skipping, breaking and falling. The inspection method is to reverse the conveyor and count the number of loose links. If there are two or more fully loose links, the chain needs to be tightened again. Keep the working surface straight. The uneven working surface will make the tension of the two chains unequal, which will cause uneven wear of the chain or cause the bottom chain to fall, jam or break. The bending of the conveyor should be appropriate, and there should be no "bright bends". The bend should be no less than eight chutes. When moving, pay attention to the cooperation of the front and rear hydraulic jacks to avoid sharp bends. Otherwise, the chute will be misaligned, which will cause a chain break and chain accident. Pay special attention to the conveyor when it is stopped. The conveyor is laid flat. Due to the limitation of the chute structure, it can only adapt to the change of 3'-5 'in the vertical direction, so the bottom surface of the working surface should be flat if there is local unevenness. And the smooth laying of the conveyor is beneficial to the operation of the scraper chain, which can reduce the chute Wear and tear while reducing power consumption. During the blasting, the transmission part of the conveyor and the pipelines, unit cables and switches must be protected. When the conveyor conveys iron and long materials, safety measures should be formulated to avoid causing personal accidents. The overlap between the transition tank tail and the middle tank is not allowed to be excessively bent. When there is a bend, wooden planks should be used. Pay special attention to the vibration of the coupling, and check the vibration of the hydraulic coupling when the conveyor starts. In order to protect the good heat dissipation conditions, the heat dissipation parts such as the cover plate should be cleaned frequently. Regular daily maintenance of the tube sheet conveyor can make the tube sheet conveyor better serve human beings, prolong its service life, and save maintenance costs.
