在轨道运输线路中,简易道岔常用于临时轨道线路,车集煤矿改进的简易道岔,加工技术合理,连接牢固,车辆运行稳定使用安全可靠。(1)简易道岔岔心的加工道岔岔心与传统岔心的区别在于,将简易道岔岔心前端加工成半圆形,其加工半径 R 应根据选用的轨型确定(如选 R=X),然后将加工好的岔心焊接在(450×350×10)mm 的钢板上(见图1),同时将1根φ20 mm 的钢筋柱焊接在岔心前端的钢 In the rail transportation lines, simple turnouts are often used in temporary track lines, car improvement of simple turnouts car set, processing technology is reasonable, solid connection, the vehicle is stable and safe to use. (1) Machining of simple turnout The difference between the turnout of turnout and traditional turnout is that the front end of the simple turnout turn is made into a semicircle. The machining radius R should be determined according to the selected track type (if R = X is selected) , And then the machined fork is welded to a (450 × 350 × 10) mm steel plate (see FIG. 1) while a steel rod of φ20 mm is welded to the front end of the steel
