A plurality of second horizontal tubes 72 are arranged in a staggered manner horizontally and vertically, and two staggered second horizontal tubes 72 are connected by bolts, thereby enclosing a third installation opening 3. Both the first installation opening 1 and the third installation opening 3 are used for the passage of the column.

[0050] Reference Figure 2 , Figure 5 The upper and lower parts of the vertical tube 73 are both slidably sleeved with the first sleeve 4, and the first sleeve 4 is bolted to the vertical tube 73. The outer wall of the first sleeve 4 is fixedly mounted with the second sleeve 5, and the first sleeve 4 and the second sleeve 5 are perpendicular to each other. The second sleeve 5 located at the upper part of the vertical tube 73 is slidably sleeved on the second horizontal tube 72, and the second horizontal tube 72 and the second sleeve 5 are bolted. The second sleeve 5 located at the lower part of the vertical tube 73 is slidably sleeved on the first horizontal tube 71, and the first horizontal tube 71 and the second sleeve 5 are bolted.

[0051] When splicing the support frame 7, the first sleeve 4 is first bolted to the vertical pipe 73, and then the first horizontal pipe 71 and the second horizontal pipe 72 pass through the second sleeve 5. The second sleeve 5 temporarily supports the first horizontal pipe 71 and the second horizontal pipe 72, thereby facilitating the splicing of the support frame 7.

[0052] Reference Figure 2 The first horizontal tube 71 , the second horizontal tube 72 and the vertical tube 73 are all provided with a plurality of through holes 6 , and the through holes 6 facilitate bolt connection between the first horizontal tube 71 , the second horizontal tube 72 and the vertical tube 73 .

[0053] Reference Figure 3 , Figure 4 The support frame 7 further includes a plurality of fixing components 74, which are distributed on the inner walls of the first mounting opening 1 and the third mounting opening 3 on both sides. The fixing components 74 include a first push rod 741, a first limiting ring 742 and a second limiting ring 743. The first push rod 741 is horizontally arranged and penetrates the through hole 6. The first limiting ring 742 and the second limiting ring 743 are both spirally sleeved on the first push rod 741.

[0054] When the fixing assembly 74 is installed on the inner walls of the two adjacent sides of the first installation opening 1, the fixing assembly 74 is located on the first horizontal tube 71. The second limiting ring 743 is first screwed into the first push rod 741, and then the first push rod 741 passes horizontally through the through hole 6 on the first horizontal tube 71, and then the first limiting ring 742 is screwed into the first push rod 741. Push the first push rod 741 against the column, and then tighten the first limiting ring 742 and the second limiting ring 743. The first limiting ring 742 and the second limiting ring 743 clamp the first horizontal tube 71, so as to facilitate fixing the column inside the first installation opening 1, and then facilitate installing the support frame 7 on the column.

[0055] When the fixing assembly 74 is installed on the inner walls of the two adjacent sides of the third installation opening 3, the fixing assembly 74 is located on the second horizontal tube 72. The first push rod 741 is passed horizontally through the through hole 6 on the second horizontal tube 72, and then one end of the first push rod 741 is screwed into the first limiting ring 742, and the other end of the first push rod 741 is screwed into the second limiting ring 743. The first push rod 741 is pushed against the column, and then the first limiting ring 742 and the second limiting ring 743 are tightened. The first limiting ring 742 and the second limiting ring 743 clamp the second horizontal tube 72, so as to facilitate fixing the column inside the third installation opening 3, and then facilitate installing the support frame 7 on the column.

[0056] Reference Figure 3 A support rod 8 is provided inside the second installation opening 2, and third sleeves 9 are fixedly installed at both ends of the support rod 8. The third sleeve 9 is sleeved on the first horizontal pipe 71, and the third sleeve 9 is bolted to the first horizontal pipe 71. A winch 10 is provided on one side of the support frame 7, and the bottom side of the winch 10 is bolted to the support rod 8, so that the winch 10 is conveniently installed on the support frame 7.

[0057] Reference Figure 4 The second horizontal tube 72 located on the side of the support frame 7 close to the winch 10 is sleeved with a fourth sleeve 11, and the fourth sleeve 11 is bolted to the second horizontal tube 72. A fixed pulley 12 is rotatably mounted on the side of the fourth sleeve 11 away from the column.

[0058] Reference Figure 6A lifting device also includes a mounting seat 13, and an automatic hook 14 is fixedly installed on the top side of the mounting seat 13. A shaft rod 15 is arranged above the mounting seat 13, and the shaft rod 15 is provided with two hooks 16. The hook 16 includes a connecting portion 161 and a hanging portion 162, and the hanging portion 162 is L-shaped. One side of the connecting portion 161 is fixedly connected to one side of the hanging portion 162, and the side of the connecting portion 161 away from the hanging portion 162 is rotatably installed on the shaft rod 15, and both ends of the shaft rod 15 are closed to limit the connecting portion 161 from sliding off the shaft rod 15. A locking assembly 17 is arranged between the two connecting portions 161, and the locking assembly 17 includes a driving rod 171, and the driving rod 171 is threaded through the two connecting portions 161. The thread directions between the two connecting portions 161 and the driving rod 171 are opposite.

[0059] When the building is a steel structure, the crossbeam of the steel structure is in an I-shape. The driving rod 171 is rotated to rotate the two hooks 16 in opposite directions, and then the two hooks 16 hook the wing plates on both sides of the crossbeam, thereby facilitating the installation of the mounting seat 13 on the crossbeam.

[0060] Reference Figure 7 , an I-beam 18 is arranged above the mounting seat 13, and an embedded plate 19 is fixedly installed on the top side of the I-beam 18. When the building is a concrete structure, the embedded plate 19 is fixed to the beam by bolt connection. The driving rod 171 is rotated to rotate the two hooks 16 in opposite directions, and then the two hooks 16 hook the wing plates on both sides of the I-beam 18, so as to facilitate the installation of the mounting seat 13 on the beam I-beam 18. The two ends of the beam I-beam 18 are fixedly installed with limit plates 20, so as to reduce the occurrence of the hook 16 sliding off the two ends of the I-beam 18.

[0061] A sheave 21 is rotatably mounted on the bottom side of the mounting seat 13, and a traction rope 22 is wound up on the winch 10. The free end of the traction rope 22 is used to connect with the prefabricated wall panel after passing through the fixed pulley 12 and the sheave 21 in sequence. The fixed pulley 12 allows the traction rope 22 to tilt toward the column, so that when the prefabricated wall panel is hoisted, the prefabricated wall panel exerts a force on the fixed pulley 12 away from the column through the traction rope 22, thereby reducing the upward force exerted by the prefabricated wall panel on the winch 10 through the traction rope 22, thereby reducing the upward sliding of the support frame 7.

[0062] At the same time, when the prefabricated wall panel pulls the winch 10 upward through the traction rope 22, the lower part of the support frame 7 close to the winch 10 is tilted, so that the upper part of the support frame 7 is tightly against the column, thereby reducing the upward sliding of the support frame 7.

[0063] A method for using a lifting device, applied to a lifting device in an embodiment of the present application, comprises the following steps:

[0064] S1. Install the support frame 7 on the column and the mounting seat 13 on the beam.

[0065] S2, connecting the prefabricated wall panel to be hoisted to the end of the traction rope 22 away from the winch;

[0066] S3, start the winch 10, and the winch 10 drives the prefabricated wall panel to rise and fall by retracting and unreeling the traction rope 22.

[0067] The implementation principle of a lifting device and a method of using the same in the embodiment of the present application is as follows: after the support frame 7 is installed on the column and the mounting seat 13 is installed on the beam, the traction rope 22 is passed through the fixed pulley 12 and the sky wheel 21 in sequence. Then the free end of the traction rope 22 is connected to the prefabricated wall panel to be lifted. Generally, a nylon sling is first put on the prefabricated wall panel, and the free end of the traction rope 22 is tied to the nylon sling, so as to connect the traction rope 22 to the prefabricated wall panel.

[0068] After the traction rope 22 is connected to the prefabricated wall panel, the hoist 10 is started to reel in the traction rope 22, thereby lifting the prefabricated wall panel. After the prefabricated wall panel is lifted, a worker is arranged to use a rope to connect with the nylon sling on the prefabricated wall panel. Then the worker pulls the rope to adjust the position of the prefabricated wall panel, thereby moving the prefabricated wall panel to the position where the prefabricated wall panel needs to be installed in the building.

[0069] The entire lifting device is inside the building, which makes it easy to close the top side of the building. After the top side of the building is closed, if it rains, the construction workers can continue to work inside the building, thus reducing the construction period.

[0070] In the lifting device of the present application, the mounting seat 13 is installed on the top side of the building, and then the traction rope 22 is connected to the platform to form a temporary elevator, thereby facilitating the construction workers to move to different floors of the building.

The second top rod 746 is threaded through the mounting block 745, and one end of the second top rod 746 is used to press against the column.

[0074] The implementation principle of the lifting device and the use method thereof in the embodiment of the present application is as follows: after the column passes through the first installation opening 1 and the third installation opening 3, the fastener 744 is inserted from top to bottom into the first horizontal tube 71 or the second horizontal tube 72. Then, the second top rod 746 is rotated to make the second top rod 746 close to the column, thereby facilitating the fixing of the support frame 7 to the column.
