The insertion plate 24 of the connecting frame 13; a quick connection mechanism 5 is provided between the two insertion plates 24, and a limit block 6 matching and snap-fitting with the quick connection mechanism 5 is connected to the top of the inner cavity of the connecting frame 13. By setting a quick connection mechanism 5 between the insertion plates 24 and the limit block 6 in the connecting frame 13 for quick connection, the first connecting member 1 and the second connecting member 2 can be quickly connected when the insertion plate 24 is inserted into the connecting frame 13, thereby improving the work efficiency of the staff and reducing the work difficulty; after the sling quickly connects all the columns 3 with the first connecting member 1 with the second connecting member 2 on the ground, the staff then reinforces them through the bolt holes 4 on the four corners of the first bottom plate 12 and the second top plate 21 with bolts and nuts, thereby shortening the working time of the sling, making the work process more streamlined, and reducing costs.

[0028] Furthermore, the width of the insertion plate 24 is equal to the width between the front and rear inner walls of the connecting frame 13; the distance between the outer walls of the two insertion plates 24 is equal to the length between the left and right inner walls of the connecting frame 13, which can play a positioning role, and after the insertion plates 24 are inserted into the connecting frame 13, the two will not move in the horizontal direction; two reinforcing plates 25 are connected between the two insertion plates 24, and the two reinforcing plates 25 are arranged vertically with the insertion plates 24. By setting the two reinforcing plates 25, the connection strength between the insertion plates 24 can be improved, and the connection strength between the first and second connecting members can be improved; and a cavity for installing the quick connection mechanism 5 is formed between the two reinforcing plates 25 and the insertion plate 24.

[0029] Furthermore, the quick connection mechanism 5 includes a clamping member 51, a fixing bolt 52 and a welding nut 53. The clamping member 51 is composed of a transverse plate 511, a longitudinal plate 512 and a clamping plate 513. The bottom ends of the two longitudinal plates 512 are connected to the two ends of the transverse plate 511 to form a "U"-shaped structure. The outer sides of the two longitudinal plates 512 are provided with a clamping plate 513 integrally formed therewith, and the outer ends of the clamping plates 513 are tilted downward; the middle parts of the transverse plate 511 and the second top plate 21 are provided with fixing bolt holes for the fixing bolts 52 to pass through, and the fixing bolts 52 are inserted into the fixing bolt holes. The welding nut 53 is fixed to the top of the bolt hole, and the fixing bolt 52 is threadedly matched with the welding nut 53; the two limit blocks 6 are square structures, and their top ends are connected to the top of the inner cavity of the connecting frame 13. A gap is provided between the outer wall of the limit block 6 and the inner wall of the connecting frame 13, and the width of the gap is equal to the thickness of the insertion plate 24; the inner wall limit portion 61 of the limit block 6, the inner end top angle of the limit portion 61 is inclined upward, and the angle between the clamping plate 513 and the longitudinal plate 512 is equal to the inner end top angle of the limit portion 61.

[0030] During installation: first weld the welding nut 53 to the top of the fixing bolt hole of the transverse plate 511, then place the clamping piece 51 in the positioning groove 26 at the top of the second top plate 21, the staff presses the clamping piece 51 with one hand, and uses the other hand to pass the fixing bolt 52 from the bottom of the second top plate 21 through the fixing bolt holes on the second top plate 21 and the transverse plate 511, and then tighten the clamping piece 51 with the welding nut 53.

[0031] Working process of the quick connection mechanism: the lifting device lifts the column 3 to the top of the second connecting member and moves downward. When the insertion plate 24 is gradually inserted into the inner cavity of the connecting frame 13 on both sides, the inner wall of the limiting portion 61 contacts the clamping plate 513, and gradually squeezes and deforms the upper ends of the clamping plates 513 and the longitudinal plates 512 on both sides toward the middle of the clamping member 51, until the clamping plate 513 passes the inner end top angle of the limiting portion 61, the clamping plate 513 and the longitudinal plate 512 return to the initial state, and the angle between the clamping plate 513 and the longitudinal plate 512 is engaged with the inner end top angle of the limiting portion 51, thereby completing the quick connection of the quick connection mechanism 5 and the limiting block 6, that is, the quick connection of the first connecting member 1 and the second connecting member 2; if a special situation occurs and the first connecting member 1 needs to be separated from the second connecting member 2, the staff can unscrew the fixing bolt 52 from the bottom of the second top plate 21 and lift the column 3 through the lifting device.

By setting the inner wall of the groove 62, the distance between the inner walls of the limiting blocks 6 on both sides gradually decreases from the bottom end to the top end. When the inner wall of the groove 62 contacts the clamping plate 513, the upper ends of the clamping plate 513 and the longitudinal plate 512 can be gradually squeezed toward the middle until the clamping plate 513 passes through the inner end top corner of the limiting portion 61, and the clamping member 51 returns to its initial state, and the clamping plate 513 is clamped with the inner end top corner of the limiting portion 61.

[0033] Furthermore, a positioning groove 26 matching the shape of the transverse plate 511 is provided in the middle of the upper surface of the second top plate 21. The positioning groove 26 can play a role in positioning and limiting the clip 51 during installation, making it easier for the staff to fix the clip 51 on the second top plate 21 through the fixing bolts 52; and in the process of tightening the clip 51 with the fixing bolts 52 and the welding nuts 53, the clip 51 will not rotate.

[0034] Furthermore, the connecting frame 23 includes a square frame 231, a connecting beam 232 and an inclined beam 233. The square frame 231 is a square frame-shaped structure. The upper surface and the lower surface of the front and rear square frames 231 are respectively connected to the second top plate 21 and the second bottom plate 22. The square frame 231 is used as a connecting piece between the second top plate 21 and the second bottom plate 22, so that when the first and second connecting pieces need to be separated, the staff can pass through the square frame 231 to unscrew the fixing bolts 52 of the quick connecting mechanism 5; preferably, the top and bottom of both sides of the two square frames 231 are connected by the connecting beam 232, and the inclined beam 233 is connected between the upper left corner and the lower right corner of the square frame 231. By setting the inclined beam 233, the supporting strength of the connecting frame 23 can be improved, and it will not affect the staff to pass through the square frame 231 to unscrew the fixing bolts.

[0035] Furthermore, the front end and rear end of the connecting frame 13 are respectively connected to the first reinforcing plates 7, and the middle of the left end and the right end of the connecting frame 13 are respectively connected to the second reinforcing plates 8. The top and bottom of the first and second reinforcing plates are connected to the first top plate 11 and the first bottom plate 12. By arranging the first reinforcing plates 7 and the second reinforcing plates 8, the supporting strength and overall structural strength of the first connecting member 1 can be improved.

[0036] Furthermore, third reinforcing plates 9 are respectively connected to both sides of the front end and the rear end of the connecting frame 23, and fourth reinforcing plates 10 are respectively connected to the middle of the left end and the right end of the connecting frame 23. The top and bottom of the third and fourth reinforcing plates are connected to the second top plate 21 and the second bottom plate 22. By providing the third reinforcing plates 9 and the fourth reinforcing plates 10, the supporting strength and overall structural strength of the second connecting member 2 can be improved.
