[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: A hoisting tool for curved curtain wall panels, such as Figure 1 As shown, the structure includes several intermediate support frames 1 that are sequentially hinged together in the left-right direction via hinges 3. The intermediate support frames 1 can swing in the front-back direction. The ends of the two intermediate support frames 1 located on the left and right outer sides are hinged together with edge support frames 2 via the same hinges 3. The hinges 3 are detachably connected to the intermediate support frames 1 and the edge support frames 2 via screws or bolts, so as to adjust the number of intermediate support frames 1 connected according to the length of different curved curtain wall panels.

[0020] Angle adjustment devices are connected to the rear sides of two adjacent intermediate support frames 1 and between adjacent intermediate support frames 1 and edge support frames 2. These angle adjustment devices are used to adjust and fix the included angles between two adjacent intermediate support frames 1 and between adjacent intermediate support frames 1 and edge support frames 2. Specifically, for example... Figure 2 As shown, the angle adjustment device includes a fixed plate 4 and a first adjustment rod fixedly mounted on the rear side of the intermediate support frame 1 and the edge support frame 2, as shown. Figure 4 As shown, the fixed plate 4 has a sliding groove 401 that is open to the left and right and extends in the front and back direction.

[0021] The first adjusting rod includes a first threaded sleeve 5 and two first lead screws 6 that are threaded to the left and right ends of the first threaded sleeve 5 respectively. The threads of the two first lead screws 6 are opposite in direction. The end of the first lead screw 6 away from the first threaded sleeve 5 is movably inserted into the slide groove 401. A first limiting nut 7 and a second limiting nut 8 that are threaded to the first lead screw 6 are fitted on it. The first limiting nut 7 and the second limiting nut 8 are located on the left and right sides of the fixed plate 4 respectively. The diameters of the first limiting nut 7 and the second limiting nut 8 are both greater than the width of the slide groove 401.

[0022] Because the first adjusting rod is subjected to a large force, in order to rotate the first threaded sleeve 5 more conveniently and effortlessly, in this embodiment, as follows: Figure 2 As shown, a plurality of levers 501 are vertically fixed on the outer side wall of the first threaded sleeve 5 and spaced around it. In use, the levers 501 can be braked and moved to rotate the first threaded sleeve 5, or an extended sleeve can be fitted onto the levers 501 to drive the first threaded sleeve 5 to rotate.

[0023] Both the intermediate support frame 1 and the edge support frame 2 are fixedly provided with a first hinge seat 9 on their front sides. The first hinge seat 9 on the intermediate support frame 1 is hingedly connected to the rear end of the second adjusting rod 10. The second adjusting rod 10 can swing left and right and its length is adjustable. The second adjusting rod 10 is a threaded sleeve structure similar to the first adjusting rod. A first connecting plate 11 is fixedly provided at the front end of the second adjusting rod 10. The front end of the first connecting plate 11 is fixedly connected to the rear end of the spring 12. A second connecting plate is fixedly provided at the front end of the spring 12. A suction cup 13 is provided on the front side of the second connecting plate. The suction cup 13 is used to adhere and fix it to the rear side of the curved curtain wall panel. In other embodiments, the spring 12 can also be replaced by other types of spring telescopic structures, such as a spring telescopic rod.

[0024] like Figure 3 As shown, the first hinge seat 9 on the edge support frame 2 is hinged to one end of a third adjusting rod 14 that can swing left and right. The length of the third adjusting rod 14 is adjustable, and the third adjusting rod 14 has a similar screw thread sleeve structure to the first adjusting rod. The end of the third adjusting rod 14 away from the edge support frame 2 is hinged to a second hinge seat 16, which is fixedly mounted on the side of the edge clamping member 15. The edge clamping member 15 can swing back and forth relative to the third adjusting rod 14. The edge clamping member 15 is used to clamp and fix the end of the curved curtain wall panel.

[0025] Specifically, such as Figure 5 As shown, the edge clamping member 15 includes a U-shaped plate 1501 with a front opening. A movable plate 1502 that can move left and right is slidably connected to the bottom of the groove of the U-shaped plate 1501. An adjusting screw 1504 threadedly connected to one side plate of the U-shaped plate 1501 is provided. One end of the adjusting screw 1504 abuts against the movable plate 1502. The adjusting screw 1504 is used to push the movable plate 1502 to slide so that the movable plate 1502 and the U-shaped plate 1501 can cooperate to clamp and fix the end of the curved curtain wall panel.

[0026] The second hinge seat 16 is fixedly connected to the side of the U-shaped plate 1501 away from the adjusting screw 1504. Anti-slip buffer pads 1505 are fixedly provided on the opposite sides of the movable plate 1502 and the U-shaped plate 1501.

[0027] The edge support frame 2 is provided with a hanger 17 extending away from the middle support frame 1, specifically, as shown in the example. Figure 3 As shown, in this embodiment, the lifting rod 17 is an L-shaped rod structure. One end of the lifting rod 17 is provided with a threaded rod head, which passes through the groove 401 of the fixed plate 4 (without an angle adjustment device) on the rear side of the edge support frame 2. Two third limiting nuts are fitted onto the threaded rod head and are threadedly connected to it. The third limiting nuts are located on the left and right sides of the fixed plate 4, respectively. A lifting ring 18 is fixedly provided on the lifting rod 17. The lifting ring 18 is located on the side of the edge support frame 2 away from the middle support frame 1.

[0028] Working principle: Before use, adjust the number of connections of the intermediate support frame 1 through hinge 3 according to the length of different curved curtain wall panels.

[0029] In use, first adjust the length and rotation angle of the third adjusting rod 14 to adjust the position of the edge clamping member 15 so that the edge clamping member 15 can clamp the end of the curved curtain wall panel. By rotating the adjusting screw 1504, push the movable plate 1502 to slide so that the movable plate 1502 and the U-shaped plate 1501 can cooperate to clamp and fix the end of the curved curtain wall panel. The anti-slip buffer pad 1504 installed on the opposite side of the movable plate 1502 and the U-shaped plate 1501 protects the end of the curved curtain wall panel.

[0030] Then, the first limiting nut 7 located between two adjacent fixed plates 4 is rotated inward to adjust its position, so that the included angle between two adjacent intermediate support frames 1 and between adjacent intermediate support frames 1 and edge support frames 2 can be adjusted. Then, the included angle between two adjacent intermediate support frames 1 and between adjacent intermediate support frames 1 and edge support frames 2 is adjusted in sequence, and the positions of the first limiting nut 7 and the second limiting nut 8 on the first lead screw 6 are readjusted so that the first limiting nut 7 and the second limiting nut 8 fix the relative position between the two fixed plates 4 again, so as to fix the adjusted included angle.

[0031] Then, adjust the length of the second adjusting rod 10 so that the suction cup 13 can be used to adhere and fix it to the rear side of the curved curtain wall panel. The spring 12 installed behind the suction cup 13 not only provides a margin for forward and backward displacement when the suction cup 13 is adhered and fixed to the rear side of the curved curtain wall panel, but also provides cushioning for the vibration of the curved curtain wall panel during hoisting.

[0032] In actual hoisting use, depending on the size of the curved curtain wall panel to be hoisted, multiple hoisting tools can be installed at the rear of the same curved curtain wall panel at the same time. Then, the slings on the crane are connected to the lifting rings on the multiple hoisting tools on the rear side of the same curved curtain wall panel to hoist the curved curtain wall panel.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
