电机车是井下运送煤炭、矸石的主要工具之一,运行正常与否将直接关系着运输任务的完成。随着井下生产的集中化和综合机械化的实现,运输负荷量不断增加,为此必须对机车进行科学管理,确保安全生产,不断提高其周转率。下面介绍的自动信、集、闭及自动拉合电可满足这一需要。 Electric locomotives are one of the main tools for transporting coal and waste rock downhole, and whether the operation is normal or not will directly affect the completion of transportation tasks. With the centralized production of underground production and the realization of comprehensive mechanization, the load of transportation is constantly increasing. Therefore, the locomotives must be scientifically managed to ensure safety in production and continuously increase their turnover rate. The following describes the automatic letter, set, closed and automatically pull together to meet this need.
