One end of the traction rod is fixed on the two connection seats 24d by bolts, and the other end is The bolt is attached to the center pin. The height of the two fixing plates 24b determines the installation height of the traction rod interface, so the high-position dual traction interface module 24 can be designed as structures of different heights.

A vertical connecting plate 24f is also arranged between the two fixing plates 24b, and the two sides of each connecting plate 24f are welded and fixed on the two opposite fixing plates 24b, and the welding position of the connecting plate 24f corresponds to the connecting seat 24d. Correspondingly, to enhance the structural strength and bearing capacity of the entire high-position dual traction interface module 24.

The adjustment of the bogie in the vertical height direction includes the installation height of the traction interface module and the interface height installed by the secondary spring device 2. In this embodiment, in order to reduce the number of interface modules and height adjustment variables, different models use the same secondary spring device 2 The spring device 2, that is, the installation height of the interface of the secondary spring device 2 of different models is the same, and the secondary spring device 2 only adjusts its lateral span, so it is necessary to adjust the traction interface module accordingly according to the installation height of the secondary spring device 2 The installation height matches the vehicle body being transported. In this embodiment, different traction rod interface modules are designed for different traction rod longitudinal positioning requirements, and different traction rod longitudinal positioning requirements are met by the traction rod interface module.

When the vehicle body is transported, first adjust the lateral span of the two sets of secondary spring devices 2 according to the requirements of the transverse span of the two sets of secondary spring devices 2, and adjust the distance between the two sets of secondary spring devices 2 and the original secondary spring devices of the vehicle. Interface height difference, adjust and determine the installation height of the traction rod interface, and select different traction rod interface modules according to the determined installation height of the traction rod interface and fasten them on the corresponding traction rod interface mounting seat 21. Through the above operations, the positioning requirements for the lateral span of the secondary spring device 2, the height of the interface of the traction rod and the longitudinal direction during the transportation of the vehicle body can be met.

Specifically, describe in detail through the following three embodiments:

Embodiment one:

As shown in Figure 21 and Figure 22, the transported car body adopts a single traction rod, such as CRH6-140/CRH6-160 and other models. When transporting the car body of this model, only two lower traction rods on a beam 8 A single traction interface module 22 is bridge-mounted on the lower position of the tie rod interface mounting seat 21a, and the single traction interface module is adjusted according to the installation height difference between the original air spring of the CRH6 model and the installation height of the secondary spring device 2 of the bogie. 22, and finally a single traction interface module 22 is bridged and fixed on the two lower traction rod interface mounts 21a on the same side by bolts.

Embodiment two:

As shown in Figure 23 and Figure 24, the car body to be transported uses low-position double traction rods, such as the Argentinian EMU. When transporting the car body of this model, two lower traction rod interface mounts 21a on the two beams 8 are required. On the top, that is, a low-position double-traction interface module 23 is installed symmetrically at the oblique angle of the low position. According to the installation height difference between the original air spring installation height of the Argentina EMU and the installation height difference between the secondary spring device 2 of this bogie, adjust the two low-position double-traction interface modules. The installation height of the interface module 23, and finally the two low-position double-traction interface modules 23 are fixed on the two lower traction rod interface mounting seats 21a by bolts.

Embodiment three:

As shown in Figure 25 and Figure 26, the transported car body adopts high-position double traction rods, such as Guangzhou Metro. When transporting the car body of this model, two upper traction rod interface mounts 21b on the two beams 8 are required. On the top, that is, a high-position double traction interface module 24 is installed symmetrically at the oblique angle of the high position. According to the installation height difference between the original air spring installation height of the Guangzhou Metro type and the installation height difference between the secondary spring device 2 of this bogie, high-position double traction interface modules of different heights are selected. Pull the interface module 24, and finally fix the two high-position double traction interface modules 24 on the two upper traction rod interface mounts 21b by bolts, avoiding the interference of the traction interface module on the vehicle body during the transportation of the conventional test vehicle body.
