[0018] The bottom support frame 1 is provided with a plurality of walking wheels 3 for easy movement and a fixing component for fixing the flipping position;
[0019] The flip assembly includes a first connecting rod 7, a second connecting rod 8, a first hydraulic rod 11, an L-shaped flip arm 5, a third connecting rod 9, a fourth connecting rod 10, and a second hydraulic rod 12. The middle position of the L-shaped flip arm 5 is connected to the base 2 through a rotating shaft 6 and is located in the middle position of the base 2. The lower end of the first connecting rod 7 is movably connected to the left side of the base 2. One end of the second connecting rod 8 is movably connected to the upper end of the first connecting rod 7, and the other end is movably connected to the upper part of the vertical part of the L-shaped flip arm 5, and the height of the connection is lower than the connection between the second connecting rod 8 and the first connecting rod 7. The lower end of the first hydraulic rod 11 is movably connected to the left side of the base 2. It is connected to the left side of the base 2, and the upper end is movably connected to the second connecting rod 8, and is close to the connection between the second connecting rod 8 and the first connecting rod 7. The left end of the third connecting rod 9 is movably connected to the right side of the base 2. One end of the fourth connecting rod 10 is movably connected to the right end of the third connecting rod 9, and the other end is movably connected to the right side of the lateral part of the L-shaped flip arm 5, and the height of the connection during flipping is always lower than the connection between the fourth connecting rod 10 and the third connecting rod 9.

[0020] In this embodiment, the fixing assembly includes a plurality of hydraulic legs 4, and the hydraulic legs 4 and the walking wheels 3 are intermittently arranged at the bottom of the bottom support frame 1; when movement is required at normal times, the hydraulic legs 4 are retracted to make the bottom wheel surface of the walking wheels 3 contact the ground, thereby facilitating movement; when the bottom support frame 1 is in a fixed position, the hydraulic legs 4 are lowered to make the walking wheels 3 leave the ground, thereby fixing the position of the bottom support frame 1; the walking wheels 3 and the hydraulic legs 4 are common technologies in the prior art and will not be elaborated here.
[0021] In this embodiment, the first connecting rod 7, the second connecting rod 8, the third connecting rod 9 and the fourth connecting rod 10 are all double-layer structures; a gasket can also be provided on the bottom support frame 1 to prevent damage to the connection between the first connecting rod 7 and the second connecting rod 8 and the connection between the third connecting rod 9 and the fourth connecting rod 10.
[0022] In this embodiment, the vertical portion of the L-shaped flip arm 5 is equal to the length of the horizontal portion; an anti-slip pile 13 is also provided on the upper portion of the vertical portion of the L-shaped flip arm 5 to prevent the box girder from sliding during the flipping process; in a normal state, the vertical portion of the L-shaped flip arm 5 can be laid flat and arranged in a line with the horizontal portion of the L-shaped flip arm 5 for easy transportation.
[0023] In the specific implementation of this embodiment:
[0024] During flipping, the first hydraulic rod 11 is shortened and the second hydraulic rod 12 is extended at the same time, thereby driving the second connecting rod 8 to move obliquely downward to the left along the first connecting rod 7, and at the same time making the first connecting rod 7 move obliquely downward to the left, and driving the L-shaped flip arm 5 to rotate to the left along the rotating shaft 6. During the rotation process, the second hydraulic rod 12 moves at the same time, driving the fourth connecting rod 10 and the third connecting rod 9 to move, making the movement process more stable. Until the flipping is completed, the vertical part of the original L-shaped flip arm 5 becomes the horizontal part located on the left side of the base 2, and the horizontal part of the original L-shaped flip arm 5 becomes the vertical part. After the flipping is completed, the flipped box girder can be changed from the original vertical welding to the flat welding, thereby improving the welding qualification rate and reducing the production cost.
