Detailed ways

Figure 1-4 is a structural schematic diagram of the present invention, a lifting and shifting type wheel set motor system maintenance platform, including a shifting box body 9, the front and rear sides of the shifting box body 9 are in the open state, and the shifting A middle plate 11 is fixed at the middle position inside the car body 9, and a lifting platform 3 is provided on the top of the shift car body 9, and a shift rack 6 is arranged on both sides of the shift car body 9, and a shift rack 6 is arranged on the top of the shift car body 9. Each of the four corners of the interior is provided with a lifting hydraulic cylinder 7, and the top of the lifting hydraulic cylinder 7 is fixedly connected with the lifting platform 3. The front and rear positions of the lifting platform 3 are each provided with a row of guide rails 10, and between the two rows of guide rails 10 is a The support device 1, the upper surface of the lifting platform 3 is provided with a guide groove 12 parallel to the guide rail 10, the support device 1 is fixed in the guide groove 12 by positioning bolts, and the wheel pair limiting device 2 is fixed on the lifting platform 3 by bolts. The limiter 2 is set on the track 10, and a fixed plate is welded to the front and rear sides of the plates on the left and right sides of the shift box body 9, and each fixed plate is fixed with a shift motor 5 by bolts. The machine heads are all designed outwards, the machine head of the displacement motor 5 is in contact with the displacement rack 6, the displacement motor 5 can move back and forth on the displacement rack 6, and both sides of the displacement compartment 9 are provided with lifting gears.
