Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0025] Wherein: by hanging the hooks 13 on both sides on the connecting parts of the prefabricated building that needs to be hoisted, the bidirectional threaded rod 6 can be driven to rotate by the servo motor 8, and the rotation of the bidirectional threaded rod 6 drives the threaded moving blocks 7 on both sides to perform translational movement in opposite directions, thereby driving the connecting rod 11 to perform translational movement, and the translation of the connecting rod 11 drives the connecting block 12 and the roller 121 to perform translational movement, thereby pulling the slings 10 on both sides to facilitate the adjustment of the positions of the two sets of hooks 13 to facilitate the hanging and installation of the prefabricated building. At the same time, after the two sets of hooks 13 are hung, they can be retracted through the two sets of connecting blocks 12 to tighten the slings 10, thereby improving the stability during hoisting.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:

[0028] As a preferred embodiment, a servo motor 8 is provided on one side of the connecting member 4, and the output end of the servo motor 8 is connected to the bidirectional threaded rod 6; further, the servo motor 8 plays a driving role and can drive the bidirectional threaded rod 6 to rotate.

[0029] As a preferred embodiment, a movable frame 14 is embedded in the middle of the hook 13, and the movable frame 14 is frame-shaped; further, the movable frame 14 plays a limiting role. When the hook 13 hoists the prefabricated building, the movable frame 14 is pressed downward and embedded in the hook 13. At the same time, the outer wall of the top of the movable frame 14 abuts against the opening of the hook 13, thereby sealing the hook 13 to prevent the hook 13 from falling off during the hoisting process.

[0030] As a preferred embodiment, a slide groove 15 is provided on the inner wall of one side of the hook 13, and a slider 16 is connected to the outer wall of one side of the movable frame 14, and the slider 16 is embedded in the slide groove 15; further, the slider 16 can slide in the slide groove 15, and the slider 16 and the slide groove 15 play a limiting role.

[0031] As a preferred embodiment, push rods 17 are provided on both sides of the top of the movable frame 14, and one end of the push rod 17 away from the movable frame 14 passes through the hook 13 and is connected to the limiting plate 18; further, the push rod 17 plays a connecting role, and the limiting plate 18 plays a limiting role.

[0032] As a preferred embodiment, a spring 19 is sleeved on the outer wall of the top rod 17 located at the bottom of the limit plate 18, and the bottom end of the spring 19 abuts against the top outer wall of the hook 13; further, the spring 19 contracts under pressure, and when the hook 13 hoists the prefabricated building, the movable frame 14 is pressed downward and embedded in the hook 13. When the hoisting is completed to the required position, the rebound force of the spring 19 pushes the limit plate 18 to translate upward. The movement of the limit plate 18 drives the top rod 17 to translate upward, thereby driving the movable frame 14 to translate upward, so that the bottom plane of the movable frame 14 is in the same straight line as the opening of the hook 13, thereby achieving the effect of automatically unhooking the hook 13.

[0033] As a preferred embodiment, a reinforcing rod 20 is provided on one side of the fixing frame 1, and rollers 21 are arranged at the bottom of the fixing frame 1; further, the reinforcing rod 20 plays a reinforcing role to improve the supporting force of the fixing frame 1, and the rollers 21 are used to facilitate the movement of the device. A counterweight is added to the lower end of the fixing frame 1 to prevent the lifting device from tilting when subjected to force.

[0034] The working process of the utility model is as follows: first, the device is moved to the desired position, and the hooks 13 on both sides are hung on the connecting parts of the assembled building that needs to be hoisted. The bidirectional threaded rod 6 can be driven to rotate by the servo motor 8. The rotation of the bidirectional threaded rod 6 drives the threaded moving blocks 7 on both sides to perform translational movement in opposite directions, thereby driving the connecting rod 11 to perform translational movement. The translation of the connecting rod 11 drives the connecting block 12 and the roller 121 to perform translational movement, thereby pulling the slings 10 on both sides to facilitate the adjustment of the positions of the two sets of hooks 13, thereby facilitating the hanging and installation of the assembled building. At the same time, after the two sets of hooks 13 are hung, they can be retracted by the two sets of connecting blocks 12 to tighten the slings 10, thereby improving the hanging. The stability during installation, when the hook 13 is hoisting the prefabricated building, the movable frame 14 is pressed downward and embedded in the hook 13, and at the same time, the outer wall at the top of the movable frame 14 abuts against the opening of the hook 13 to seal the hook 13 to prevent the hook 13 from falling off during the hoisting process. When the hoisting is to the required position, the rebound force of the spring 19 pushes the limit plate 18 to move upward, and the movement of the limit plate 18 drives the top rod 17 to move upward, thereby driving the movable frame 14 to move upward, so that the bottom plane of the movable frame 14 is in the same straight line with the opening of the hook 13, thereby achieving the effect of automatically unhooking the hook 13. The above is the working principle of this kind of hanging and easy-to-install prefabricated building hoisting device.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
