一、断链保护的意义在现在煤矿矿井中,维护链板运输机安全地运转,是保证煤炭连续运输的重要环节,尤其对于集中和连镇控制的运输机,装有自动保护装置,更显得必要。刮板运输机经常发生断链事故,对于就地控制的运输机,工人可以及时发现加以处理。但对于集中和自动控制2台以上的运输机,一般每台运输机附近并无固定工人管理,如果发生断链事故而又无自动保护装置时,主电动机仍然继续运转,使断了的链子将从星轮上脱落下来,搭在下
First, the significance of broken chain protection Coal mine shaft in the present, the safe operation of chain conveyor maintenance is an important part of coal to ensure continuous transport, especially for centralized and even transport control town, equipped with automatic protection device, even more necessary. Scraper conveyor often happen chain scission accident, for local control of transport aircraft, workers can be found in time to be addressed. However, for centralized and automatic control of more than two transport aircraft, there is generally no fixed worker management near each transport aircraft. In the event of a chain breaking accident without an automatic protective device, the main electric motor continues to operate, so that the broken chain will move from star Turn off the wheel, take the next ride
