[0028] Embodiment 2:

[0029] like Figure 1-Figure 4 As shown, the lifting device for steel structure installation disclosed in the second embodiment of the utility model has a structure basically the same as that in the first embodiment, except that a movable hole 11 is provided on the bottom surface of the lifting clamping plate 6, and a movable block 12 is provided inside the movable hole 11 for movement, a driving motor 13 is fixed to one side of the lifting clamping plate 6, and a screw rod 14 is provided inside the movable hole 11 for rotation, a plurality of anti-deflection rods 15 are fixed to one side of the buffer plate 9, and a spring 10 surrounds the outer wall of the anti-deflection rod 15, a plurality of through holes 16 are provided on one side of the extrusion plate 8, and the other end of the anti-deflection rod 15 passes through the through hole 16, and two limit holes 17 are respectively provided on the inner top and bottom surfaces of the placement groove 7, and a limit block 18 is provided inside the limit hole 17 for sliding, and the two sides of the extrusion plate 8 are respectively fixed to one side of the limit block 18.

During buffering, the anti-deflection rod 15 and the through hole 16 can support and block the spring 10 to prevent the spring 10 from tilting, thereby making the fixed support more stable. The limiting hole 17 and the limiting block 18 can make the extrusion plate 8 more stable during extrusion and fixation to prevent shaking.

[0032] like Figure 1-Figure 4 As shown, the lifting device for steel structure installation disclosed in the third embodiment of the utility model has a structure basically the same as that in the second embodiment, except that a protective pad 19 is fixed to one side of the inner wall of the placement groove 7, and the protective pad 19 is made of rubber.
