[0023] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0024] like Figure 1 As shown, this embodiment provides an auxiliary device for disassembling and assembling brake discs of subway trains. The device includes a plurality of mutually connected supporting modules, and in this embodiment, two supporting modules are used to form the auxiliary device.

[0025] Each support module includes a base 1, a support column 2, a V-shaped plate 4 and a side bar 3. The support column 2 is vertically installed at both ends of the base 1, and the horizontal cross-section of the support column 2 is concave, and the concave notches of the two support columns 2 are arranged opposite to each other. The two sides of the two support columns 2 are respectively connected to the side bars 3, and the side bars 3 and the support columns 2 are detachably connected by bolts or snaps, etc., and can be easily removed or installed from the support columns 2. Specifically, one end of each side bar 3 is connected to one side of the support column 2 at one end of the base 1, and the other end is connected to the same side of the support column 2 at the other end of the base 1. The V-shaped plate 4 is installed on the base 1, and the V groove of the V-shaped plate 4 is upward, and the two ends are respectively connected to the support columns 2 on both sides of the base 1.

[0026] The two support modules are connected side by side through the base 1. The device is also provided with a reinforcing rod 8, which is arranged between two adjacent support modules, one end of the reinforcing rod 8 is connected to the support column 2 of one support module, and the other end is connected to the support column 2 of the same end of the other support module. The horizontal installation of the reinforcing rod 8 can make the device have better tensile resistance in the horizontal direction, not easy to tip over, and obtain better stability.

[0027] The working principle of this embodiment is: the V-shaped plate at the bottom of the device can stably fix the cylindrical wheel cake 9, ensuring that the wheel cake 9 will not move up and down and can remain upright; the support column 2 with a concave horizontal cross-section can ensure that the wheel cake 9 will not fall or turn over after the side guard rod 3 is removed.

[0028] When removing the brake disc 10 , install the wheel cake 9 connected to the brake disc 10 into the device, first unscrew the fixing bolts of the brake disc 10 and the wheel cake 9 , then open the side guard bar 3 and take out the brake disc 10 .
