Detailed ways

The utility model will be further described below by way of specific embodiments:

Please refer to Fig. 1 and Fig. 2 at the same time, wherein Fig. 1 is an axonometric view of the transport platform movable laterally according to the present invention, and Fig. 2 is a schematic diagram of its laterally moving state. The transversally movable transport platform includes a frame 1 , legs 2 , front wheels 3 , rear wheels 7 , drawbars 5 , connecting rods 6 , and quick release pins 4 . Wherein, the legs 2 are arranged on the outer frame of the frame 1 , the front wheels 3 and the rear wheels 7 are respectively arranged at the four corners of the frame 1 , and the connecting rod 6 is arranged between the two front wheels 3 and connected with the drawbar 5 .

Please refer to Fig. 3 and Fig. 4 at the same time, wherein Fig. 3 is a schematic structural view of the front wheel, and Fig. 4 is an axonometric view of the front wheel. Described front wheel 3 comprises wheel 8, has an outrigger type wheel fork 9 with jack, three-hole T-shaped plate 10, mandrel 11, lower bearing 17, upper bearing 16, axle sleeve 12, pressing plate 13, Spring washer 14, compression nut 15. Wherein, the front wheel 3 is welded on the frame 1 through the axle sleeve 12 . The three-hole T-shaped plate 10 has a long end and a short end perpendicular to each other, and a hole is arranged at both ends of the long end and the short end, and the three-hole T-shaped plate 10 is lightly sleeved on the mandrel 11 . The lower bearing 17 is arranged around the mandrel 11 and the bushing 12 , and the mandrel 11 transmits force to the frame 1 through the lower bearing 17 and the bushing 12 to ensure upward force transmission. Upper bearing 16 is housed on mandrel 11 and axle sleeve 12 tops, guarantees mandrel 11 to rotate flexibly. The pressing piece 13 is arranged on the upper bearing 16, and is pressed and fixed by the compression nut 15, and the force is transmitted to the frame 1 through the compression nut 15 and the pressing piece 13, thereby preventing the platform from falling off when the platform is raised.
