The bearing frame 1 is rectangular and is configured to be connected to a hoisting device. A hoisting hole that passes through in the vertical direction is provided on the bearing frame 1; the two hoisting structures 2 are arranged in parallel and at intervals in the hoisting holes in the horizontal direction, and each hoisting structure 2 includes a hoisting beam 21 and two moving components 22.

[0036] Before the lifting operation, the load-bearing frame 1 is first connected to the lifting equipment. According to the size of the hoisted panel, the lifting structure 2 is moved along the load-bearing frame 1, and the distance between the two lifting structures 2 is adjusted to ensure that the load-bearing frame 1 is balanced in force and can remain horizontal when lifted by the lifting equipment. The lifting structure 2 is then locked to the load-bearing frame 1, and the moving component 22 is pushed along the lifting beam 21. The distance between the two moving components 22 on each lifting beam 21 is adjusted to ensure that the panel to be lifted can always remain horizontal during the lifting process.

The two bearing beams 11 are arranged in parallel and spaced apart in the horizontal direction; the connecting beam 12 is fixedly connected between the two bearing beams 11; the connecting ring 13 is fixedly sleeved on the bearing beams 11, and the connecting ring 13 is configured to be connected to a lifting device. With the above arrangement, the bearing beams 11 and the connecting beams 12 are spliced ​​with each other to form the bearing frame 1, which has a simple structure and low production cost. At the same time, the connecting ring 13 is welded to the bearing beams 11, and the connection strength is high.

[0038] More specifically, the connecting ring 13 is provided with a slot which penetrates along its circumference, and the sling of the lifting equipment can be inserted into the slot to prevent the sling from shaking in the air, thereby improving the stability and safety of the lifting operation.

In other embodiments, the number of connecting rings 13 can also be increased according to the actual needs of the hoisting operation, which is not limited here.

[0040] In this embodiment, the hoisting beam 21 is an I-beam, including a web and two wing plates, and the moving assembly 22 includes two second pulleys 221, which are respectively slidably arranged on both sides of the web of the hoisting beam 21 and vertically abut between the two wing plates of the hoisting beam 21. The above arrangement enables the moving assembly 22 to slide along the extension direction of the hoisting beam 21 through the second pulleys 221, with a simple structure, low production cost, low friction, and easy to push by construction personnel.

[0041] Specifically, the moving assembly 22 further includes a lifting lug 222, and both ends of the lifting lug 222 are rotatably provided with a second pulley 221.

[0043] In this embodiment, the second locking hole and the second locking member 223 cooperate with each other through threads, and the second locking member 223 is screwed to lock or unlock the moving assembly 22 to the hanging beam 21. In other embodiments, the second locking member 223 may also be a pin or a rivet, which is not limited here.

[0044] Specifically, a slide groove 111 is provided on the load-bearing beam 11, and the bottoms of the slide grooves 111 on the two load-bearing beams 11 are arranged opposite to each other, and first pulleys 211 are rotatably provided at both ends of the hoisting beam 21, respectively, and the first pulleys 211 extend into the slide groove 111 and abut against the bottom of the slide groove 111.

[0045] In this embodiment, the first pulley 211 is rotatably connected to the wing plate of the lifting beam 21 , and two first pulleys 211 are respectively provided at both ends of each wing plate of the lifting beam 21 .

[0046] More specifically, the hoist further includes a first locking member (not shown in the figure), and a first locking hole is formed on the first pulley 211.

[0047] In this embodiment, the first locking hole and the first locking member cooperate with each other through threads, and the first locking member is turned to lock or unlock the hanging beam 21 to the load-bearing beam 11. In other embodiments, the first locking member may also be a pin or a rivet, which is not limited here.

[0048] More specifically, a folded edge 112 is provided at the opening of the slide slot 111, and the first pulley 211 can abut against the folded edge 112. The provision of the folded edge 112 can increase the force points of the first pulley 211 and improve the stability of the hoisting beam 21 when it moves along the load-bearing beam 11. In this embodiment, the load-bearing beam 11 is a C-shaped steel, including two wing plates and a web plate, and the ends of the two wing plates of the load-bearing beam 11 away from the web plate of the load-bearing beam 11 are both provided with a folded edge 112.

[0049] More specifically, the hoisting structure 2 further includes two clamping plates 23, which are respectively arranged at both ends of the hoisting beam 21. The clamping plates 23 extend into the slide slot 111 and abut against the bottom of the slide slot 111 and the folded edge 112. The above arrangement can prevent the hoisting beam 21 from being separated from the load-bearing beam 11 during the hoisting process, thereby improving the safety of the hoisting device.

[0050] Specifically, the bearing frame 1 further includes four diagonal bracing rods 14, which are arranged one by one at the four vertices of the bearing frame 1. The arrangement of the diagonal bracing rods 14, in which both ends of each diagonal bracing rod 14 are respectively connected to the bearing beam 11 and the connecting beam 12, can prevent the bearing frame 1 from being deformed during the hoisting process, and overcome the defect of the instability of the rectangular structure.
