The cross-shaped frame 4 includes two T-shaped frames 4A on the left and right. The space between the two T-shaped frames 4A is the space for placing the large workpiece 2; when the large workpiece 2 is in the hoisting and assembly state, the height of the cross-shaped frame 4 is greater than the height of the large workpiece 2; the T-shaped frame 4A includes a horizontal frame 4A1, and the upper plane of the horizontal frame 4A1 at the same height as the ground 1A is the walking plane for assembly personnel. When the large workpiece 2 is hoisted into the cross-shaped frame 4 and the cross-shaped frame 4 drives the large workpiece 2 to turn 180 degrees through the power rotary device 3A and the passive rotary device 3C, the upper plane of the horizontal frame 4A1 is still at the same height as the ground 1A.
[0005] As a further solution of the present invention: The turning machine 3 includes a movable bracket 5 that does not affect the rotation of the cross-shaped frame 4. The two ends of the movable bracket 5 are respectively installed on the left and right T-shaped frames 4A; when the large workpiece 2 is in the hoisting state, the movable bracket 5 is located at the bottom of the cross-shaped frame 4, and the movable bracket 5 supports the two ends of the large workpiece 2.

[0007] As a further solution of the present invention: the power rotation frame 3B includes a rotation drive 3B1, and the power rotation device 3A drives the rotation of the cross frame 4 through the rotation drive 3B1.
[0008] As a further solution of the present invention: the cross frame 4 includes transverse steel 4Y, angle steel 4C and 4 H-shaped steels 4H. The 4 H-shaped steels 4H are symmetrically arranged, and the upper and lower adjacent H-shaped steels 4H are connected into one body by the transverse steel 4Y.
[0009] As a further solution of the present invention: the large equipment includes the "ultra-large excavator" in construction machinery, and the large workpiece 2 includes the longitudinal beam in the "ultra-large excavator".
[0010] In summary, compared with the traditional technology, in the present invention, the turnover of the large workpiece in the production workshop is realized by the turnover machine installed in the pit, and through ingenious design, the upper plane of the horizontal frame in the turnover machine is flush with the ground, which not only overcomes the disadvantages of the traditional operation of turning the large workpiece in the air by the overhead crane in the production workshop, but also greatly facilitates the assembly operation of the operators on the ground, which is both safe and convenient.
