A left connecting cavity 8 is provided in the left sleeve 1. The left connecting cavity 8 is arranged along the length direction of the left sleeve 1. The inner surface of the side wall of the left connecting cavity 8 is provided with left connecting internal threads. The right end of the left connecting screw 2 is connected and arranged in the left connecting cavity 8 by thread connection. The left extrusion disc 3 is connected and arranged at the left end of the left connecting screw 2;

[0028] A right connecting cavity 9 is provided in the right sleeve 4. The right connecting cavity 9 is arranged along the length direction of the right sleeve 4. The inner surface of the side wall of the right connecting cavity 9 is provided with right connecting internal threads. The left end of the right connecting screw 5 is connected and arranged in the right connecting cavity 9 by thread connection. The right extrusion disc 6 is connected and arranged at the right end of the right connecting screw 5;

[0029] The right end of the left sleeve 1 is connected to the left end of the right sleeve 4. One end of the connecting cable 7 is connected to the left sleeve 1, and the other end of the connecting cable 7 is connected to the right sleeve 4.

[0030] The I-beam 14 includes two flanges and a web between the two flanges. When hoisting the I-beam using the I-beam lifting tool structure of the present utility model, it is preferably to use two groups of auxiliary hoisting components. First, the hoisting personnel bypass the connecting cable 7 around the two flanges of the I-beam 14 so that it is located above the web of the I-beam 14, and at the same time, the left sleeve 1, the left connecting screw 2, the left pressing disc 3, the right sleeve 4, the right connecting screw 5, and the right pressing disc 6 are located between the two flanges and below the web; then rotate the left connecting screw 2 and the right connecting screw 3 respectively, so that the left connecting screw 2 drives the left pressing disc 3 to move towards one flange, and the right connecting screw 5 drives the right pressing disc 4 to move towards the other flange until the left pressing disc 3 and the right pressing disc 4 are respectively abutted against the inner side walls of the two flanges of the I-beam, and the auxiliary hoisting component is fixed to the I-beam 14. Finally, the hook of the hoisting device is hung on the connecting cable 7, and the hoisting device hoists the I-beam 14. It can be seen that the hoisting of the I-beam 14 can be realized through the I-beam lifting tool structure of the present utility model, and the I-beam lifting tool structure has a simple structure, is convenient to use, is convenient for hoisting the I-beam 14, and is conducive to large-scale use.

[0031] Specifically, the right end of the left connecting screw 2 is threadedly connected and arranged in the left connecting cavity 8, and the left connecting screw 2 can move left and right in the left connecting cavity 8 by rotation; the left end of the right connecting screw 5 is threadedly connected and arranged in the right connecting cavity 9, and the right connecting screw 5 can move left and right in the right connecting cavity 9. To facilitate the rotation of the left connecting screw 2 and the right connecting screw 3, as shown in Figure 1 , Figure 2 and Figure 3 again, a left rotating handle 10 is connected between the left connecting screw 2 and the left pressing disc 3, and a right rotating handle 11 is connected between the right connecting screw 5 and the right pressing disc 6. The hoisting personnel act on the left rotating handle 10 to rotate the left connecting screw 2, and act on the right rotating handle 11 to rotate the right connecting screw 5.

[0032] Since the rotation of the left connecting screw 2 will drive the rotation of the left pressing disc 3, and the rotation of the right connecting screw 5 will drive the rotation of the right pressing disc 6, this will affect the abutting effect of the left pressing disc 3 and the right pressing disc 4 against the inner side walls of the two flanges of the I-beam, and it is not convenient for the hoisting personnel to rotate the left connecting screw 2 and the right connecting screw 5. To make it more convenient to rotate the left connecting screw 2 and the right connecting screw 5, as shown in Figure 1 , Figure 2 and Figure 3As shown in the figure, a left rotating block 12 is connected to the left side of the left connecting screw rod 2.

A right rotating block 14 is connected to the right side of the right connecting screw rod 5. A right rotating groove is provided in the right pressing disc 6. The right rotating block 14 is fitted in the right rotating groove and can rotate in the right rotating groove. Such a setting makes the left pressing disc 3 not rotate with the left connecting screw rod 2, and the right pressing disc 6 not rotate with the right connecting screw rod 5, which is more convenient for the hoisting personnel to use and ensures the tight contact effect between the left pressing disc 3, the right pressing disc 4 and the inner side walls of the two flanges of the I-beam. To further facilitate the rotation of the left connecting screw rod 2 and the right connecting screw rod 5, a plurality of evenly distributed left rotating balls 13 are arranged at intervals in the circumferential direction of the left rotating block 12. The left rotating balls 13 are located between the left rotating block 12 and the side wall of the left rotating groove. A plurality of evenly distributed right rotating balls are arranged at intervals in the circumferential direction of the right rotating block 14.

[0033] To reduce the possibility of damage to the I-beam 14, the left pressing disc 3 and the right pressing disc 4 during hoisting and improve the tight contact effect between the left pressing disc 3, the right pressing disc 4 and the inner side walls of the two flanges of the I-beam, anti-slip pads 15 are respectively provided on the left surface of the left pressing disc 3 and the right surface of the right pressing disc 6. The anti-slip pads 15 are preferably rubber pads.

[0034] To facilitate the connection between the left sleeve 1 and the right sleeve 4 and facilitate the use of the auxiliary hoisting assembly, for another example Figure 1 、 Figure 2 As shown in the figure, the right end of the left sleeve 1 and the left end of the right sleeve 4 are detachably connected together through a middle connection structure 16.

[0035] To ensure the use effect of the I-beam hoist structure and improve the stability of the I-beam 14 during hoisting, for another example Figure 4 、 Figure 5As shown, the I-beam sling structure includes two groups of auxiliary hoisting components. The middle parts of the connecting cables 7 of the two groups of auxiliary hoisting components are crossed and overlapped together. The position where the middle parts of the two connecting cables 7 are crossed and overlapped is the hanging point of the hook of the hoisting device. In order to more conveniently arrange the connecting cable 7 and facilitate the connection between the I-beam sling structure and the I-beam 14, the present utility model further provides a hoisting point concentration member 19. The connecting cable 7 includes a first cable body part and a second cable body part.
