井口推车机的研制与改造

The developement and reform of the pusher at the entrance of mine

针对普通钢丝绳推车机在使用过程中存在的缺陷 ,结合原系统研制了新型液压推车机 ,解决了频繁出现的机电故障。介绍了改造后液压推车机装置的工作原理。

Accounting to the limitation of the normal steel-rope pusher during the course of using,the paper,based on the existing system,developes a new kind of hydraulic pusher,and resolves the electromechanical breakdowns usually occured.Also,this paper introduces the working principle,structure and the specialties of the reformed hydraulic pusher.
