[0002] In the production and maintenance of self-propelled equipment, the storage of bogies is undoubtedly very important. At present, bogies are generally stored individually on rails. This storage method has many defects. For example, when bogies with different track gauges need to be stored, rails of corresponding track gauges need to be built, which consumes a lot of manpower and material resources. Moreover, they can only be stored individually, with low space utilization. When stored for a long time, the wheel tread may be worn due to uneven rails and surface impurities, which reduces the service life. Utility Model Content

[0011] A further improvement is that the bogie located at the bottom layer is provided with a wheelset support device, the wheelset support device comprises a pad, and the pad is provided with two pads adapted to the wheels of the bogie.

[0012] A further improvement is that the wheelset supporting device also includes a buffer block, a bracket is provided on the top of the pad, the bottom of the buffer block is inserted into the bracket, and a limiting inclined surface is provided on the top of the buffer block for supporting the bogie wheel; the top surface of the pad is a slope surface adapted to the limiting inclined surface.
