盾构刀盘支撑法兰位于切口环内,主要作用是将刀盘与主驱动连接起来,驱动刀盘的旋转。盾构刀盘支撑通过法兰盘与主驱动齿轮相连,刀盘在旋转过程中连接的密封位极易进入泥砂,长期旋转过程中容易造成密封位的磨损,因此法兰盘在掘进一定距离后必须进行检查、修复。某法兰盘为宽740mm,中心直径2 740mm的圆环,并连接6个牛腿。为防止该法兰盘的变形,采取镶嵌钢环加补焊的修复工艺,达到了法兰盘变形量小、平面精度高的目的。 Shield cutterhead support flange is located in the notch ring, the main role is to connect the cutterhead and the main drive, drive cutterhead rotation. Shield cutterhead support through the flange and the main drive gear connected to the cutter during the rotation of the sealing position is easy to enter the silt, the long-term rotation process is likely to cause the sealing position of the wear and tear, so the flange in the driving a certain distance Must be checked, repaired. A flange is a wide 740mm, center diameter of the ring 2 740mm, and connected to six cow legs. In order to prevent the deformation of the flange, to take the steel ring plus welding repair process to achieve a small deformation of the flange, the plane of high precision purposes.
