A plurality of frame beams are divided into two groups according to weight, one group is lighter, and the other group is heavier. The lighter frame beam is connected to the group of lugs 300 arranged near the first end of the introduction beam 100 during installation, and the heavier frame beam is connected to the group of lugs 300 arranged far from the first end of the introduction beam 100 during installation.

[0052] Specifically, the first connecting ear plate 200 can be fastened to the tower crane hook 700 via a pin shaft, thereby achieving a fastened connection between the first end of the introduction beam 100 and the tower crane hook 700 .

[0053] It should be noted that the structure of the tower crane hook is well known to those skilled in the art and does not constitute the core of the improvement, so its specific structure will not be described in detail here.

[0054] In one embodiment, the attachment frame installation device also includes a second connecting ear plate 400 and a support member 500, the second connecting ear plate 400 is arranged on the bottom surface of the first end of the introduction beam 100, and the support member 500 has a first connecting end and a second connecting end that are relatively arranged, the first connecting end is connected to the second connecting ear plate 400, and the second connecting end extends downwardly in a direction away from the second end of the introduction beam 100, and is used to connect to the tower crane hook 700.

[0057] In one embodiment, the distance between the first connection end and the second connection end is adjustable, so as to effectively improve the versatility of the support member 500 and be applicable to the connection between the introduction beam 100 and tower crane hooks 700 of different specifications.

[0058] In one embodiment, referring to Figure 5 As shown, the support member 500 includes an intermediate connecting rod 501, a joint 502 and a main support rod 503, one end of the joint 502 is connected to the first end of the intermediate connecting rod 501 and the connection position is adjustable along the axial direction of the intermediate connecting rod 501, and the other end is the first connection end, one end of the main support rod 503 is connected to the second end of the intermediate connecting rod 501 and the connection position is adjustable along the axial direction of the intermediate connecting rod 501, and the other end is the second connection end.
