The third connecting portion 7 may be connected between the supporting seat 40 of the third positioning structure 3 and the supporting seat 40 of the fourth positioning structure 4, and other details of the third connecting portion 7 are similar to those of the first connecting portion 5, so that they will not be described herein.

The fourth connecting portion 8 may be connected between the supporting seat 40 of the first positioning structure 1 and the supporting seat 40 of the third positioning structure 3, and other details of the fourth connecting portion 8 are similar to those of the second connecting portion 6, so that they will not be described herein.

In an exemplary embodiment of the present disclosure, as shown in fig. 1, in order to further enhance the strength of the shipping fixture 100, the surfaces of the first connection part 5, the second connection part 6, the third connection part 7, and the fourth connection part 8 may be provided with reinforcing ribs 70, and the reinforcing ribs 70 may be fixed to the first connection part 5, the second connection part 6, the third connection part 7, or the fourth connection part 8 by intermittent welding so as to reduce welding deformation.

In an exemplary embodiment of the present disclosure, in order to further enhance the supporting strength of the shipping fixture 100, a reinforcing rib may be provided between the connection parts, for example, a first reinforcing rib 51 may be provided between the first connection part 5 and the second connection part 6; a second reinforcing rib 61 is arranged between the second connecting part 6 and the third connecting part 7; a third reinforcing rib 71 is arranged between the third connecting part 7 and the fourth connecting part 8; fourth reinforcing ribs (not shown) are provided between the fourth connecting portion 8 and the first connecting portion 5.

While the shipping fixture 100 of the present disclosure is carrying different models of locomotive frames, there may be different functions of the second support portion 20 and the third support portion 30, for example:

As shown in fig. 9, when the shipment tool 100 of the present disclosure carries the HXD 3C-type locomotive frame 200, the positioning seat on the side beam of the HXD 3C-type locomotive frame 200 mainly contacts the shipment tool 100 of the present disclosure, the first supporting portion 10 on the shipment tool 100 may be used for supporting, the second supporting portion 20 may stop the locomotive frame in the X direction, and the third supporting portion 30 may stop the locomotive frame in the Y direction.

As shown in fig. 10, when the shipment tool 100 of the present disclosure carries the FXD1 locomotive frame 300, the head shaking stop on the side beam of the FXD1 locomotive frame 300 mainly contacts the shipment tool 100 of the present disclosure, and at this time, the first supporting portion 10 on the shipment tool 100 plays a supporting role, the second supporting portion 20 may stop the locomotive frame in the Y direction, and the third supporting portion 30 may stop the locomotive frame in the X direction.
