蒸汽机车在牵引运行中,无论采用人工焚火还是采用人工与加煤机联合焚火方式,都需要将煤水车煤槽中部与后部的煤移送到取煤口附近,才能顺利进行焚火作业。因此,乘务员要利用焚火间歇时间去煤水车扒煤,既增加劳动强度,又影响前途瞭望,危及行车安全。为了保证行车全安,改善乘务员劳动条件,自五十年代以来,一些局、段先后在蒸汽机车上试装自行研制的推煤机,并取得了一定效果,但都存在不同的缺点。由哈尔滨铁路局科
In the traction operation, steam locomotives need to move the coal in the middle and the rear of the coal tanker to the vicinity of the coal intake to fire smoothly, regardless of whether manual fire burning or manual fire-burning combined with stoker is used. Therefore, the flight attendants should use the intermittent incineration time to coal-water coal mills, which not only increase the labor intensity, but also affect the prospects, endangering traffic safety. In order to ensure the safety of traffic and to improve the working conditions of flight attendants, some bureaus and departments have experimented with self-developed coal pulverizers on steam locomotives since the 1950s and achieved some success. However, they all have different shortcomings. From Harbin Railway Bureau
