During hoisting, the double-sided bracket 1 provides bottom support for the bottom wall of the flange plate 31 and provides lateral limit for the outer side wall of the flange plate 31, realizing the relative fixation between the flange plate 31 and the double-sided bracket 1.

[0023] The hoisting member 2 is arranged on the top of the double-sided bracket 1 and is used to be erected above the flange plate 31 of the I-beam 3 for hoisting. During hoisting, under the hoisting action, the double-sided bracket 1 provides bottom support for the bottom wall of the flange plate 31 of the I-beam 3, provides lateral limit for the outer side wall, and drives the flange plate 31 of the I-beam 3 to shift, realizing the hoisting of the I-beam 3. Specifically, the hoisting member 2 is arranged on the top of the double-sided bracket 1. During hoisting, the double-sided bracket 1 is clamped on the flange plate 31 of the I-beam 3. At the same time, the hoisting member 2 is located above the flange plate 31 of the I-beam 3 to facilitate connecting the lifting rope 4. The two ends of the lifting rope 4 are respectively connected to the hoisting members 2 of the two hoisting fixtures, and by hoisting the middle position of the lifting rope 4, the two double-sided brackets 1 of the two hoisting fixtures can be respectively clamped on the two side flange plates 31 of the I-beam 3. And under the action of the hoisting tension, the two double-sided brackets 1 provide bottom support for the bottom walls of the flange plates 31 of the I-beam 3 and provide lateral limit for the two outer side walls. In this embodiment, the hoisting member 2 and the top end of the double-sided bracket 1 can be connected by welding or other connection methods, and the connection method is not limited in this embodiment.

[0024] Continue to refer to Figures 1 to 3 , the double-sided bracket 1 includes: a positioning bracket plate 11 and a positioning web control plate 12; wherein, the positioning bracket plate 11 is used to provide bottom support for the bottom wall of the flange plate 31 of the I-beam 3; the positioning web control plate 12 is arranged perpendicular to the positioning bracket plate 11, and one long side of the positioning web control plate 12 is connected to one long side of the positioning bracket plate 11 to form an L-shaped structure. The positioning web control plate 12 is used to press against and contact the outer side wall of the flange plate 31 of the I-beam 3 to realize the horizontal direction limit of the I-beam 3.

[0025] Specifically, the positioning bracket plate 11 and the positioning abdominal control plate 12 are vertically arranged, and one long side of the positioning abdominal control plate 12 is connected to one long side of the positioning bracket plate 11 to form an L-shaped structure, that is, the double-sided bracket is in an L-shaped structure, so as to respectively support the bottom wall of the flange plate 31 of the I-beam 3 through the positioning bracket plate 11 and laterally limit the outer side wall. In this embodiment, the positioning bracket plate 11 and the positioning abdominal control plate 12 are of an integral structure and can be formed into an integral structure by bending.

[0026] Continue to refer to Figures 1 to 3 , the lifting member 2 includes: a card slot positioning top plate 21 and a lifting plate 22; wherein, one long side (such as Figure 2 the right side shown) of the card slot positioning top plate 21 is connected to the top end of the double-sided bracket 1, and a card slot structure 5 is formed by enclosing between the card slot positioning top plate 21 and the double-sided bracket 1 to be clamped on the flange plate 31 of the I-beam 3; the lifting plate 22 is arranged above the card slot positioning top plate 21 along the cross-section of the card slot positioning top plate 21, and the bottom end of the lifting plate 22 is connected to the top wall of the card slot positioning top plate 21, and a lifting hole 221 is provided on the lifting plate 22 for connecting the lifting rope 4.

[0027] Specifically, the card slot positioning top plate 21 and the positioning bracket plate 11 of the double-sided bracket 1 are arranged at an angle, and the angle between them is an acute angle so as to be adaptable to the stretching of the lifting rope 4. Among them, from the closed end (such as Figure 2 the left end shown) of the card slot structure 5 to the open end (such as Figure 2 the right end shown) of the card slot structure 5, the distance between the card slot positioning top plate 21 and the positioning bracket plate 11 of the double-sided bracket 1 gradually increases, so that the card slot positioning top plate 21 is inclined towards the lifting direction of the lifting rope 4, that is, as Figure 3 shown, the right lifting rope segment deflects upward from right to left, and the right card slot positioning top plate 21 also deflects upward from right to left. The lifting plate 22 is arranged above the card slot positioning top plate 21 along the cross-section of the card slot positioning top plate 21, and one long side (such as Figure 2 the right side shown) of the lifting plate 22 is connected to the other side (such as Figure 2 the right side shown) of the card slot positioning top plate 21, and the two can be connected by welding or fixed connection in other ways. The lifting plate 22 is provided with a lifting hole 221 penetrating through the lifting plate 22 along its thickness direction, and the lifting rope 4 can be connected to realize lifting.

Among them, the hoisting hole 221 can be of a circular or elliptical structure. Of course, it can also be other through-hole structures, and no limitation is made to it in this embodiment.

[0028] In this embodiment, the hoisting plate 22 includes a rectangular plate and an arc plate structure arranged on the top of the rectangular plate to form a special-shaped plate structure. Among them, the arc plate structure convexly arranged on the top of the rectangular plate can facilitate the opening of the hoisting hole 221 and ensure the stability of the hoisting plate 22 at the hoisting hole 221. Preferably, the arc plate structure is a structure that is narrow at both ends and wide in the middle.

[0030] Furthermore, the hoisting plate 22 is provided with a hoisting hole 221 that penetrates the hoisting plate 22 along its thickness direction. The structure is simple, and it can provide a more stable hoisting fulcrum, making the lifting tool more convenient to use. In addition, since the hoisting hole 221 is opened close to the overall opening of the lifting tool, it ensures the accuracy of the direction and positioning of the force provided by the lifting tool itself, has stronger practicability for the use environment, reduces the number of manual operations, speeds up the hoisting speed, saves time and effort, achieves twice the result with half the effort, and increases the safety factor.
