Specific implementation manner

[0023] Please refer to Figures 1-5 , a maintenance flipping table for an EMU seat, comprising: a base 1, moving wheels 2 are installed at the bottom of the base 1, and the moving wheels 2 can easily move the device to a designated position, thereby reducing the time and labor consumed by manual handling. A rotating shaft 7 is fixed at the right side position of the top of the base 1, and a flipping plate 8 is fixed on the rotating shaft 7. The flipping plate 8 is rotationally connected to the base 1 through the rotating shaft 7. A flipping mechanism 6 is arranged on the base 1. The flipping mechanism 6 realizes the automatic flipping of the flipping plate 8 through the driving motor and the threaded lead screw for screw drive, reducing the complexity and labor intensity of manual operation and providing stable power output.

[0024] Improve work efficiency. A control panel 12 is arranged on the front side of the base 1, and a counterweight box 3 is arranged on the left side of the base 1. The counterweight box 3 can provide additional weight to help maintain the overall stability of the device and reduce the risk of shaking or tipping during the flipping process of the EMU seat 11. A motor placement box 4 is arranged on the counterweight box 3, a push rod 5 is fixed above the counterweight box 3, a support plate 10 is slidably connected to the left side of the flipping plate 8, and fixing bolts 9 are threadedly connected to the left and right sides of the flipping plate 8. An EMU seat 11 is placed above the flipping plate 8, and the EMU seat 11 is fixed to the flipping plate 8 through the fixing bolts 9. The fixing bolts 9 can fix EMU seats 11 of different sizes to meet the maintenance requirements of various models of EMU seats 11.

[0025] The flipping mechanism 6 includes a driving motor 61, a threaded lead screw 62, a threaded nut 63, and a support rod 64. A groove matching the threaded lead screw 62 is formed at the top of the base 1. The threaded lead screw 62 is rotatably connected to the groove formed in the base 1. The threaded nut 63 is threadedly sleeved on the threaded lead screw 62. One end of the support rod 64 is hinged to the threaded nut 63, and the other end of the support rod 64 is hinged to the bottom of the flipping plate 8. The driving motor 61 is fixed to the leftmost side of the threaded lead screw 62 and is placed in the motor placement box 4. The motor placement box 4 is provided with heat dissipation holes to dissipate heat from the driving motor 61, preventing heat accumulation from damaging the driving motor 61. The control panel 12 is designed with two control buttons for rising and falling, and the control panel 12 is electrically connected to the driving motor 61. Pressing the rising button on the control panel 12 starts the driving motor 61, which drives the threaded lead screw 62 to rotate. The thread on the threaded lead screw 62 contacts the threaded nut 63, thereby driving the threaded nut 63 to move to the right along the threaded lead screw 62. Since the support rod 64 is hinged to the bottom of the flipping plate 8, the support rod 64 drives the flipping plate 8 to rotate through the rotating shaft 7 until the flipping plate 8 is flipped to a vertical angle. The driving motor 61 and the threaded lead screw 62 perform a screw drive to achieve automatic flipping, reducing the complexity and labor intensity of manual operation, providing stable power output, ensuring the accuracy and repeatability of the flipping action, significantly improving work efficiency, and shortening the maintenance time.

[0026] Four moving wheels 2 are installed at the four corners of the bottom of the base 1. The flipping plate 8 has an L-shaped structure, and two hollow grooves are formed in the flipping plate 8.
