[0018] See also Figure 1 and Figure 2 , a preferred embodiment of the utility model includes:

[0019] An adjustable lifting tool for steel structure parts, the adjustable lifting tool for steel structure parts comprises: a hanging plate 1, a hanger 2, an end plate 3, a hook 5 and a sling 4, the hanger 2 is made of a square steel pipe with a total length of 15 meters, the hanging plate 1 is welded and fixed to the middle position of the top of the hanger 2, a lifting head protruding upward is provided in the middle of the hanging plate 1, a lifting hole 101 is provided in the middle of the lifting head, and a sling length adjustable connecting structure and a cable entry hole 203 penetrating the side wall of the hanger 2 are symmetrically provided on both sides of the hanger 2, the cable entry hole 203 is a long hole with a length of 30 cm, and is arranged at a distance of 100 meters from the hanger 2 on both sides. At a position about 20 cm from the end, there are two end plates 3 which are respectively welded and fixed on the ends at both ends of the hanger 2. A cable outlet hole 301 is provided in the middle of each end plate 3. There are two slings 4 which are respectively installed on both sides of the hanger 2. One end of each sling 4 can be detachably installed on the adjustable connecting structure of the sling, and the other end first passes through the cable inlet hole 203 to enter the hanger 2 and then passes through the cable outlet hole 301 in the middle of the end plate 3 fixed at the top of the hanger 2. The passing directions of the two slings 4 are opposite, and a hook 5 is installed on the end passing through the cable outlet hole 301.

[0020] The length-adjustable connection structure of the sling 4 is composed of 10 connection plates 201 welded and fixed on the same side of the hanger 2 and 11 threading guardrails 202 welded at intervals between the connection plates 201 and between the connection plates 201 and the cable entry hole 203. All the connection plates 201 are arranged on the same horizontal line. The distance between any two adjacent connection plates 201 and any two threading guardrails 202 is equal, which is 1 meter. Each connection plate 201 is provided with a through connection hole. The end of the sling 4 is equipped with a corresponding U-shaped detachable connector, which can be hinged with any connection plate 201 through the connection hole. In this way, the actual adjustment range of the sling 4 can be as high as 9 meters by adjusting the connection between the U-shaped detachable connector and different connection plates 201 during hoisting, which can meet the hoisting requirements of large components of different lengths. Moreover, when the sling 4 is installed, the cable body passes through the gap between the threading guardrail 202 and the hanger 2 to prevent the cable body of the sling 4 from falling when not in use.

[0021] Reinforcement ribs are provided between the hanging plate 1 and the hanger 2, and the reinforcement ribs are symmetrically arranged on both sides of the hanging plate 1.
