Embodiment 1
[0044] Embodiment 1. The present invention is a rail transit vehicle maintenance and overhaul device. The present invention is aimed at the maintenance and repair of small rail transit vehicles in cities. For small rail transit vehicles in cities, it includes a locomotive 1, and the locomotive 1 The rear end is connected with a car body 2, and the car body 2 includes a bottom plate 3 fixedly connected to the upper end of the chassis, see Figure 4 , the vehicle head 1 and the vehicle body 2 are connected via the storage table 4, please refer to figure 2 , the upper end of the storage table 4 is fixed with a support column 5 along the vertical direction, and a lifting column 6 is threaded in the support column 5 along the vertical direction, so that the lifting column 6 moves along the vertical direction when rotating, and the lifting column 6 The upper end of the column 6 is rotatably connected with the hanging plate 7 extending to the upper end of the bottom plate 3. When th...
Embodiment 2
[0051] Embodiment 2, on the basis of Embodiment 1, in order to make the lifting column 6 complete the lifting better, please refer to Image 6 , Figure 9 with Figure 11 , Figure 12 , the drive connection device includes a first gear 11 arranged in rotation on the upper end of the support column 5, the first gear 11 is screwed with the lifting column 6, and the first gear 11 is in rotation with the storage table 4, because when the first When the gear 11 rotates, it is limited and cannot move in the vertical direction, and then the lifting column 6 is rotated. Since the lifting column 6 and the support column 5 are threadedly arranged, the lifting column 6 is moved in the vertical direction when rotating. When the first gear 11 rotates, it drives the lifting column 6 to rotate and move vertically. The first gear 11 is meshed with a second gear 12 that rotates with the storage table 4. The outer side of the second gear 12 is coaxially fixed with a Extended to the first dri...
Embodiment 3
[0053] Embodiment 3, on the basis of Embodiment 2, in order to make the ejector rod 9 lift the vehicle to be repaired better, please refer to Figure 4 , Figure 5 with Figure 7 , Figure 8 The driving connection device also includes a turbine 14 placed at the lower end of the base plate 3, the turbine 14 is arranged in rotation with the base plate 3, the turbine 14 is sleeved on the outside of the push rod 9 and is threadedly arranged with the push rod 9, so that the When the worm gear 14 rotates, it drives the push rod 9 to rotate and move vertically, and the worm gear 14 is engaged with a worm screw 15 arranged in cooperation with the rotation of the base plate 3;
[0054] In the specific use of this embodiment, first, the vehicle is transported to the upper end of the base plate 3, and the vehicle at this time is placed on the upper end of the push rod 9, and then rotates by driving the worm 15, and then the worm gear 14 meshed with the worm 15 completes the synchronous...
