Specific embodiments

[0024] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] The directions involved in the following text are based on Figure 1 the directions of the components in

[0026] As Figures 1 to 5 shown, the auxiliary hoisting device of the present utility model includes at least one group of auxiliary hoisting components. The auxiliary hoisting components include a left sleeve 1, a left connecting screw 2, a left pressing disc 3, a right sleeve 4, a right connecting screw 5, a right pressing disc 6 and a connecting cable 7. A left connecting cavity 8 is arranged 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 arranged in the left connecting cavity 8 in a threaded connection and matching manner. The left pressing disc 3 is connected and arranged at the left end of the left connecting screw 2;

[0027] A right connecting cavity 9 is arranged 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 arranged in the right connecting cavity 9 in a threaded connection and matching manner. The right pressing disc 6 is connected and arranged at the right end of the right connecting screw 5;

[0028] 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.

[0029] The I-beam 14 includes two flanges and a web between the two flanges. When using the auxiliary hoisting device of the present utility model to hoist the I-beam, preferably two groups of auxiliary hoisting components are used. First, the hoisting personnel pass 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 disk 3, the right sleeve 4, the right connecting screw 5, and the right pressing disk 6 are located between the two flanges and below the web. Then, the left connecting screw 2 and the right connecting screw 3 are rotated respectively, so that the left connecting screw 2 drives the left pressing disk 3 to move towards one flange, and the right connecting screw 5 drives the right pressing disk 4 to move towards the other flange until the left pressing disk 3 and the right pressing disk 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 auxiliary hoisting device of the present utility model, and the auxiliary hoisting device has a simple structure, is convenient to use, is convenient for hoisting the I-beam 14, and is conducive to large-scale use.

[0030] Specifically, the right end of the left connecting screw 2 is arranged in the left connecting cavity 8 in a threaded connection and matching manner, and the left connecting screw 2 can move left and right in the left connecting cavity 8 when rotated; the left end of the right connecting screw 5 is arranged in the right connecting cavity 9 in a threaded connection and matching manner, and the right connecting screw 5 can move left and right in the right connecting cavity 9. For the convenience of rotating the left connecting screw 2 and the right connecting screw 3, as shown in Figure 1 、 Figure 2 and Figure 3 shown, a left rotating handle 10 is connected between the left connecting screw 2 and the left pressing disk 3, and a right rotating handle 11 is connected between the right connecting screw 5 and the right pressing disk 6.

[0031] Since the rotation of the left connecting screw 2 will drive the rotation of the left pressing disk 3, and the rotation of the right connecting screw 5 will drive the rotation of the right pressing disk 6, this will affect the abutting effect of the left pressing disk 3 and the right pressing disk 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. For the convenience of rotating 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. This 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 effect of the left pressing disc 3 and the right pressing disc 4 pressing against the inner side walls of the two flanges of the I-beam. In order 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. The right rotating balls are located between the right rotating block 14 and the side wall of the right rotating groove.

[0032] In order 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 effect of the left pressing disc 3 and the right pressing disc 4 pressing against the inner side walls of the two flanges of the I-beam, anti-slip pads 15 are respectively provided on the left side surface of the left pressing disc 3 and the right side surface of the right pressing disc 6. The anti-slip pads 15 are preferably rubber pads.

[0033] In order 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.

[0034] In order to ensure the use effect of the auxiliary hoisting device and improve the stability of the I-beam 14 during hoisting, for another example Figure 4 、 Figure 5As shown, the auxiliary lifting device includes two groups of auxiliary lifting components. The middle parts of the connecting cables 7 of the two groups of auxiliary lifting components are crossed and overlapped together. The position where the middle parts of the two connecting cables 7 are crossed and overlapped is the lifting point of the hook of the lifting device. In order to more conveniently arrange the connecting cable 7 and facilitate the connection between the auxiliary lifting device and the I-beam 14, the present utility model further provides a lifting point concentration member 19. The connecting cable 7 includes a first cable body part and a second cable body part. One end of the first cable body part is connected to the left sleeve 1, the other end of the first cable body part is detachably connected to the lifting point concentration member 19, one end of the second cable body part is connected to the right sleeve 4, and the other end of the second cable body part is detachably connected to the lifting point concentration member 19.
