机车锅炉烟管(如图1),由于材料关系,經常是用气焊来焊接。焊接时要一个人转动,一个人焊接,而且組裝时間較长。在生产大跃进中,我們做了一个轉胎,不但节省了一个劳动力,而且提高了工作效率。 轉胎的构造如图2,管子放在轉胎上,脚踩开关7压縮空气就通过胶皮管6进入风鑽1内,风鑽就带动主动輪轉动起来,主动輪8带动被动輪2和主动軸4轉动。主动軸上的摩擦輪就靠着摩擦力的关系带动焊件轉动,并且
Locomotive boiler pipe (Figure 1), due to material relations, often welded with gas welding. Welding to a person to rotate, a person welding, and assembly time longer. In the Great Leap Forward of Production, we made a tire change that not only saved a workforce, but also increased our work efficiency. Tire structure shown in Figure 2, the tube on the tire, foot switch 7 compressed air through the rubber tube 6 into the pneumatic drill 1, the pneumatic drill to drive the drive wheel to rotate, the drive wheel 8 drives the driven wheel 2 and Drive shaft 4 rotates. The friction wheel on the drive shaft drives the weldment to rotate by the frictional force
