SS1型电力机车砂箱盖是一个很不引人注意的小部件,但由于设计上的缺陷,它曾给我段运用和检修工作造成不少困难。其原因就是经常丢失。根据我段的实际情况,我们对砂箱盖作了一些改造。实际证明,改造效果很好。 1.改造前存在的问题如图1所示,原设计将支架焊在砂箱侧面,砂箱盖由压指压住。由于机车运行中频繁剧烈振动,砂箱盖随之振动,机车运行一段时间后,压指内部的作用弹簧会出现压力不足和失灵现象,加上上砂人员有时安装压指不到位,砂箱盖容易从边框处脱落,掉在支架下面。机车在运行中,掉在支架下面的砂箱盖作
SS1 electric locomotive flask cover is a very unobtrusive small parts, but due to design flaws, it has given me the use of section and maintenance work caused many difficulties. The reason is often lost. According to the actual situation in our paragraph, we made some modifications to the flask lid. Actual proof, the transformation effect is very good. 1. Existing problems before the transformation As shown in Figure 1, the original design of the bracket welded on the side of the flask, the flask cover pressed by the pressure. As locomotives frequently violent vibration, sand box cover along with the vibration, the locomotive running for a period of time, the role of the pressure refers to the internal pressure of the spring there will be inadequate pressure and failure, coupled with the sand and sometimes the installation pressure is not in place, sand box cover Easy to fall off the border, fall under the bracket. Locomotive in operation, fell off the bracket under the sand box for
