[0028] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0029] Reference Figure 1 A universal storage and transport rack for bogie wheelsets and axles, comprising a base frame 1 and an axle frame 2.

[0030] The base frame 1 is a rectangular frame, and a protective plate can be installed on the surface of the base frame 1 to avoid rigid collisions with the base frame 1 during the installation of the bogie wheelsets and axles. Two pairs of wheel frames 11 for supporting the front and rear wheels 4 are fixedly installed on the base frame 1, and each pair of wheel frames 11 is arranged in a V-shape.

[0031] The axle bracket 2 consists of two parts, front and rear, which are respectively hinged to the base frame 1. The top of the axle bracket 2 is a V-shaped frame 21 for supporting the axle 5.

[0032] Reference Figure 3 When the shaft bracket 2 is in the retracted state, it is located in the hollow middle position of the base frame 1;

[0033] Reference Figure 2 When the shaft frame 2 is in the unfolded state, it is at a 90-degree angle to the base frame 1 and is fixed to the base frame 1 by the locking device 3.

[0034] A longitudinal beam 12 is provided on the base frame 1, and the longitudinal beam 12 is welded to the bottom of the base frame 1. The shaft frame 2 is hinged to the longitudinal beam 12 via a hinge 13. The locking device 3 includes a sleeve 31 located on the longitudinal beam 12, and a pin 32 for insertion into the sleeve 31 is provided on the shaft frame 2. A pin sleeve 33 is provided outside the pin 32, and a handle 321 is provided on the pin 32. A vertical slot 331 is opened on the pin sleeve 33 to allow the handle 321 to move. When the axle bracket 2 needs to be in the unfolded state, simply rotate the axle bracket 2 outward around the longitudinal beam 12 via the hinge 13. When the axle bracket 2 is at a 90-degree angle to the base frame 1, move the handle 321 downward along the vertical seam 331 so that the pin 32 is inserted into the sleeve 31 to lock the axle bracket 2 and the base frame 1. Thus, the V-shaped bracket 21 on the axle bracket 2 provides support for the axle 5. When the axle bracket 2 needs to be in the retracted state, simply pull the handle 321 upward along the vertical seam 331. When the handle 321 leaves the vertical seam 331, rotate the handle to place the handle 321 on the pin sleeve 33. At this time, the pin 32 leaves the sleeve 31. Simply rotate the axle bracket 2 inward around the longitudinal beam 12 via the hinge 13 to retract the axle bracket 2 into the hollow middle position of the base frame 1.

[0035] This product has a forklift hole 14 at the bottom of the base frame 1 for forklift transportation. The forklift hole 14 is formed by welding two “П”-shaped steel bars, one at the front and one at the rear, to the bottom of the base frame 1.

[0036] The wheel frame 11 and the V-frame 21 of this product are provided with nylon pads to better protect the wheel 4 and the axle frame 2.

[0037] This invention can be switched at will between wheelset storage and transportation mode and axle storage and transportation mode. It has a simple structure and is easy to operate, thereby reducing the manufacturing cost of storage and transportation devices. At the same time, it saves a lot of resources and labor in the storage and transportation of wheelsets and axles.

[0038] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
