Figure 5-6 As shown, support plates 9 are arranged at the four corners and sides of the bottom of the main stage steel frame, and a horizontal rotary support device 8 and a moving wheel group are arranged in sequence below the support plate.

[0032] Combination Figure 7-14 As shown, the moving wheel group includes four driving wheel groups 5 and two driven wheel groups 6. The driving wheel group 5 is located at the four corners of the bottom of the main stage steel frame, and includes a running wheel 5.1, a running wheel seat 5.2 and a transmission wheel group 5.3. The driven wheel group 6 is located at the side of the bottom of the main stage steel frame, and includes a running wheel 6.1 and a running wheel seat 6.2. The horizontal slewing support device includes a thrust bearing 8.4, a first flange 8.2 and a second flange 8.5 from top to bottom.
