They are mainly prefabricated and processed in a standardized manner in the production factory, and then transported from the production factory to the construction site. By reserving lifting holes, lifting rings or other lifting embedded parts on the top of the prefabricated concrete exterior wall, the lifting chain of the on-site tower crane passes through the lifting ring, and the prefabricated concrete exterior wall is lifted by the cooperation of the lifting chain and the lifting ring, and then hoisted to the installation location by the tower crane for positioning and installation.

[0020] Figure 1 It is a structural schematic diagram of the utility model. Figure 2 The schematic diagram of the structure of the limiting bracket 2 in the utility model is shown in the figure: the prefabricated wall hoisting device of this embodiment includes a device body 1 and a limiting bracket 2 arranged at both ends of the device body 1, at least two sets of hoisting components are arranged on the device body 1 along the length direction, and the hoisting components are used to hoist the prefabricated wall, and the limiting bracket 2 is arranged below the end of the device body 1 and is used to contact and limit the prefabricated concrete outer wall; the prefabricated wall may include a prefabricated assembled concrete outer wall, a prefabricated assembled concrete outer wall panel, a prefabricated concrete outer wall panel, a prefabricated Prefabricated concrete exterior walls, etc., the various prefabricated walls are all pre-embedded with lifting embedded parts on the top, which are used to cooperate with the lifting components of the prefabricated wall lifting device for lifting; the device body 1 can be a balance beam, a steel plate, etc., and the balance beam can adopt an I-beam with an I-shaped cross-section. In this embodiment, a steel plate is used as the device body 1; at least two groups of lifting components are arranged to ensure that during the lifting process, the force exerted on the tower crane hook 9 can be distributed to each lifting component by the lifting embedded parts, thereby improving the overall rigidity and avoiding the influence of sudden uneven force on the prefabricated wall.

[0021] In this embodiment, the device body 1 is provided with a plurality of lifting holes 3 along the length direction, and the lifting holes 3 are used to install the lifting assembly; the plurality of lifting holes 3 are arranged equidistantly along the length direction of the device body 1, and when the installation position of the lifting assembly is adjusted, the distance of the position change of the lifting assembly can be ensured to be controllable.

[0022] In this embodiment, the lifting assembly includes a buckle 4 and a hook 6, and the buckle 4 and the hook 6 are connected by a lower lifting rope 5. The buckle 4 is detachably mounted on the lifting hole 3; the hook 6 is used to cooperate with the lifting embedded parts pre-embedded at the top of the prefabricated wall to lift the prefabricated wall. The hook 6 is detachably mounted on the lifting hole 3 through the buckle 4, and the position of the hook 6 can be adjusted. The position of the hook 6 can be adjusted according to prefabricated walls of different sizes. At least two groups of the lifting assembly are arranged. Taking two groups of lifting assemblies as an example, the positions of the two groups of lifting assemblies installed on the lifting hole 3 need to ensure that the center of gravity of the prefabricated wall coincides with the center of gravity of the tower crane hook 9 during the lifting process, so as to ensure that the movement of the prefabricated wall during the lifting process is more stable.

[0023] In this embodiment, the limiting bracket 2 is perpendicular to the device body 1 and can be telescopically adjusted in length to limit the contact with the precast concrete exterior wall; the limiting bracket 2 is arranged at both ends of the device body 1 and realizes lateral limitation of the precast wall by contacting the precast wall.

[0024] In this embodiment, the position limiting tripod 2 includes a sleeve 10 and a telescopic section 11 sleeved on the sleeve 10, the sleeve 10 is provided with a plurality of pin holes 12 along the length direction, and the telescopic section 11 is provided with a positioning lock pin 13 matched with the pin hole 12, which is used to adjust the length of the telescopic section 11; the sleeve 10 and the telescopic section 11 are coaxially arranged, and the maximum adjustable length of the sleeve 10 and the telescopic section 11 is at least greater than the highest height of the prefabricated wall to be hoisted, which can ensure that the position limiting tripod 2 can be applied to prefabricated walls of different heights during the hoisting process; the pin holes 12 are equidistantly arranged along the length direction of the sleeve 10, and the positioning lock pin 13 is arranged on the side wall near the top of the telescopic section 11, such as Figure 2 As shown, when the limit bracket 2 is not extended or retracted, the positioning lock pin 13 on the telescopic section 11 is embedded in the first pin hole 12 on the sleeve 10, so that the telescopic section 11 is sleeved in the sleeve 10. When the prefabricated wall is hoisted, the limit bracket 2 is adjusted according to the height of the hoisted prefabricated wall. After the positioning lock pin 13 embedded in the first pin hole 12 is pressed and retracted, the telescopic section 11 is pulled downward until the overall length of the sleeve 10 and the telescopic section 11 is greater than or equal to the height of the prefabricated wall. At this time, the positioning lock pin 13 is embedded in the corresponding pin hole 12 to position the sleeve 10 and the telescopic section 11, thereby adjusting the length of the limit bracket 2.

[0025] In this embodiment, two lifting ears are symmetrically fixed to the upper end of the device body 1 along the length direction, and the two lifting ears are respectively connected to the tower crane hook 9 through the upper lifting rope 8. The tower crane hook 9 is located in the middle directly above the balance steel plate; the symmetrical arrangement of the two lifting ears can ensure that when the tower crane hook 9 lifts the device body 1 through the upper lifting rope 8, the center of gravity of the tower crane hook 9 can coincide with the center of gravity of the device body 1, so that the device body 1 can be in a horizontal state, reducing shaking when lifting the prefabricated wall.

[0026] A limit tripod 2 is arranged below the ends of both ends of the device body 1. The length of the limit tripod 2 is adjusted according to the height of the prefabricated wall by cooperating with the positioning locking pin 13 on the telescopic section 11 and the pin hole 12 on the sleeve 10 to ensure that the limit tripod 2 limits the prefabricated wall laterally during the lifting process. A detachable lifting component is installed on the device body 1. The lifting embedded parts arranged on the top of the prefabricated wall are lifted by the hook 6 of the lifting component so that it is on the same vertical line as the pre-selected lifting point position. Two lifting ears are symmetrically fixedly connected to the upper end of the device body 1 along the length direction. The symmetrical arrangement of the two lifting ears can ensure that when the tower crane hook 9 lifts the device body 1 through the upper lifting rope 8, the center of gravity of the tower crane hook 9 can coincide with the center of gravity of the device body 1. The tower crane hook 9 cooperates with the use of the lifting component and the lifting ears to ensure that the center of gravity of the tower crane hook 9, the device body 1 and the prefabricated wall are on the same vertical line during the lifting process, thereby achieving stable lifting.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
