[0041] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0042] A bogie switching device, such as Figure 1 and Figure 2 Shown, including:

[0043] Bottom rail 5, arranged to cross the main track;

[0044] A mobile platform and two transition rails 9 are provided on the mobile platform. The transition rails 9 are parallel to the main rails 12, and the spacing between the two transition rails 9 is consistent with the spacing between the two main rails. Under the action of the mobile platform, the transition rails 9 move axially along the bottom rail 5 until they are aligned with the main rails.

[0045] A plurality of wheelset fixing blocks 3 are arranged on the transition track 9 .

[0046] By designing a movable platform, the transition track 9 moves axially along the bottom rail under the action of the mobile platform to align with the main track, so that it can be aligned with the two sections of the main track respectively. During the switching process, there is no need to reload and unload, and the switching can be smooth and fast.

[0047] In most embodiments, the bottom rail 5 and the main rail are arranged perpendicularly. Generally, there are two bottom rails 5. This can improve stability and reduce the travel distance and occupied area during movement.

[0048] In addition, the device also includes two fixed platforms, which are located on both sides of the mobile platform, and the projection of the fixed platform on the axis of the transition track 9 and the projection of the mobile platform on the axis of the transition track 9 overlap by more than 90%;

[0049] Correspondingly, the mobile platform includes:

[0050] Mobile frame 10,

[0051] A plurality of bottom rail wheels 6 are provided at the bottom of the mobile frame 10 and cooperate with the bottom rail 5.

[0052] The upper cover 7 is provided on the top of the moving frame 10.

[0053] Two movable cover plates 8 are respectively provided on both sides of the movable frame 10, and the projection of the movable cover plate 8 on the axis of the transition track 9 and the projection of the upper cover plate 7 on the axis of the transition track 9 have an overlap rate of more than 90%;

[0054] A slot for inserting the movable cover 8 is provided in the fixed platform.

[0055] The overlap rate of the projection of the fixed platform on the axis of the transition track and the projection of the mobile platform on the axis of the transition track exceeds 90%. In this way, combined with the movable cover, the pit will not be exposed during the translation of the bogie, thereby improving safety.

[0056] In the process of left and right translation, part of the pit will be exposed. Without the operation of on-site workers, operators or parts may fall into the pit due to uncertain factors, bringing great safety hazards. Therefore, in this embodiment, by designing the above structure, the pit will not be exposed during the translation of the bogie, and the pit will be completely covered, thus eliminating a great safety hazard.

[0057] In some embodiments, the stationary platform comprises:

[0058] a fixed frame, wherein the slot is provided in the fixed frame;

[0059] A fixed pedal 2 is provided on the top of the fixed frame;

[0060] The support column 1 is arranged at the bottom of the fixed frame.

[0061] Generally, a stop block 4 is provided on the side of the fixed pedal 2 close to the movable platform, and a movable roller 11 is provided on the movable cover 8, thereby reducing resistance.

[0062] In most embodiments, the upper surfaces of the fixed pedal 2 and the upper cover plate 7 are flush with each other without forming a step, thereby improving safety.

[0063] In most embodiments, a plurality of support columns 1 are provided at the bottom of the fixed frame, and in some embodiments, a bottom rail 5 is fixed to the ground by screws.

[0064] A wheelset fixing block 3 is installed on the upper portion of the mobile platform. This effectively restrains the bogie wheelset within the groove, making it easier for operators to push the bogie and preventing it from being pushed too far. A stop block is also installed on the inner side of the fixed pedal to limit the space for left and right translation, ensuring that the translation position is precisely aligned with the rail to be connected. This device greatly facilitates the operation of on-site operators and improves work efficiency.

[0065] The operation process of this application is as follows: the bogie to be transferred is pushed onto the mobile platform of the mobile device, specifically the front and rear wheel pairs are in the transition track 9. When the front and rear wheel pairs of the bogie enter the wheel pair fixed block 3, the bogie has been pushed to the correct position. The bogie is pushed from the side to enable the mobile platform to move along the bottom rail 5. Specifically, the bottom track wheel 6 supports the mobile frame 10, the upper cover plate 7, and the transition track 9 to move along the bottom rail 5. Since the movable cover plate 8 is connected to the mobile frame 10, the movable cover plate 8 will also move together. There is space inside the fixed platform 2, which allows the movable cover plate 8 to move inside it. In order to reduce the movement resistance of the movable cover plate 8, a movable roller 11 is installed at the front end of the movable cover plate 8 to reduce unnecessary resistance. After the bogie is pushed to the correct position, the bogie can be pushed to the track to be transferred.
