摘要
针对大庆130型钻机手柄连杆式机械排挡装置使用中存在的问题,研制了气控排挡装置,其特点是各挡挂摘时能自锁和互锁,操作安全;还可通过压力表的显示判断各牙嵌离合器的挂摘情况,从而改善工人的劳动条件,获得显著的经济效益。
A type of pneumatic gear--shifting apparatus is developedto take the place of the existing mechanical linking-rod onewhich shows many problems in application. This apparatusis characterized by self-locking and inter--locking in the caseof gear engaging or disengaging and by safe operation andgood economic effects.
