Embodiment Construction
[0019] The manufacturing method of the track iron backing plate structure in the track traffic engineering of the present invention is described in conjunction with the accompanying drawings.
[0020] The design concept of the new iron backing plate structure of the rail transit engineering track of the present invention is based on: the original iron backing plate is also divided into three areas: the spike fixing area I, the supporting rail area II, and the spring strip fixing area III. The thickness is the same, generally 20mm, and can be appropriately reduced if necessary. The biggest difference between the structure of the iron backing plate and the original iron backing plate is that the thickness of the spike fixing area I remains unchanged. After the finite element analysis calculation and the actual project application test, the most reasonable 20mm is used, and it can be appropriately reduced if necessary. figure 2 As shown, the thickness values of the supporting ...
