Several lower horizontal bars 6 are placed parallel to each other below the upper horizontal bar 4 in the same pattern, with ball-joint components 5 connecting adjacent lower horizontal bars 6. Several reinforcing rods 7 are placed in a serrated pattern between the upper horizontal bar 4 and the lower horizontal bar 6. The upper end of each reinforcing rod 7 is fixedly connected to the upper horizontal bar 4 via a ball-joint component 5, and the lower end of each reinforcing rod 7 is obliquely fixedly connected to the lower horizontal bar 6 via a ball-joint component 5. The longitudinal and transverse reinforcing rods 7 connect all the upper horizontal bars 4 and lower horizontal bars 6 into one unit. A main horizontal plate 3, parallel to the upper horizontal bar 4, is provided above the middle upper horizontal bar 4. The length of the main horizontal plate 3 is less than that of the lower horizontal bar 6.

The upper horizontal bar 4 is fixedly connected to multiple sets of ball joints 5. Moreover, the upper horizontal bar 4, lower horizontal bar 6 and reinforcing bar 7 provided in the ball joint lifting device can form multiple sets of triangular frame structures through the cooperation of the ball joints 5, which can effectively enhance the overall structural strength of the ball joint lifting device and also effectively enhance the overall load-bearing capacity of the ball joint lifting device, making the ball joint lifting device adaptable to complex stress environments. In addition, it can enhance the lifting effect of the ball joint lifting device on the main body of the steel skeleton 9.
