货车拱板式转向架轴箱和拱架柱螺栓拆卸相当困难,我厂起先是人用扳手拆,后来改用5-5-5牌风动扳机,二人操作,有时拆不下就割掉。在双革运动中,我们制成了两套螺栓拆卸机,这两套拆卸机安装在固定台位轨道两侧的地坑内,把转向架推到固定台位,开动拆卸机就可同时拆卸转向架两侧的轴箱和拱架柱螺栓。估计比过去提高效率4倍多,初步计算全年可节约6000元,而且大大地减轻了 Truck truck plate bogie axle and arch column bolt removal is quite difficult, I plant was the first wrench removed, and later switched to 5-5-5 licensing pneumatic trigger, two operations, and sometimes can not split on the cut off. In the double leather movement, we made two sets of bolt disassembler, the two sets of demolition machine installed in the pit on both sides of the fixed platform track, the bogie to the fixed station, start the demolition machine can be removed at the same time turn Shafts and arch studs on both sides of frame. Estimated to be more than four times more efficient than in the past, the initial calculation can save 6,000 yuan a year, and greatly reduce
