[0037] With reference to Figure 1 , Figure 2 and Figure 4 , the moving beam 9 is horizontally arranged above the middle support leg 1, the left and right ends of the moving beam 9 are arranged above the corresponding longitudinal main beam 14, so that the moving beam 9 is displaced along the length direction of the longitudinal main beam 14, specifically, the two ends of the moving beam 9 are provided with track wheels 10, and the top and bottom of the longitudinal main beam 14 are provided with tracks matched with the track wheels 10 and the electric hanging wheel 5.
[0038] With reference to Figures 1-4, the bracket is arranged between the moving suspension beam 9 and the transverse track 2, so that the transverse track 2 is lifted synchronously with the longitudinal main beam 14, and then the transverse track 2 is displaced along the length direction of the longitudinal main beam 14 synchronously with the middle support leg 1 and the moving suspension beam 9.
