Technical Field
[0001] This utility model relates to the field of assembly lifting equipment technology, and in particular to a lifting equipment for installing prefabricated components of prefabricated buildings. Background Technology
[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are prefabricated in factories and then transported directly to the construction site, such as floor slabs, wall panels, stairs, and balconies. They are then assembled and installed on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, and assembly construction, they represent modern industrialized production methods.
[0003] In the prior art, when assembling prefabricated building components, a crane is needed to lift and move the components to the target location for assembly. In traditional methods, the components are mostly fixed to the crane using a single lifting device such as a rope, which is not very flexible. When facing different assembly requirements, the horizontal angle of the components during installation cannot be quickly adjusted, and manual adjustment of the installation angle is required, which affects the assembly speed of prefabricated components. Therefore, in order to solve the above problems, this utility model proposes a lifting device for installing prefabricated building components. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a lifting device for installing prefabricated components of prefabricated buildings. By adjusting the horizontal angle of the lower lifting frame through a servo motor, the device's flexibility during the lifting process is improved, making it easier to adjust the installation angle of the lifted components to meet different assembly requirements, shortening the assembly time, and effectively increasing the assembly speed of prefabricated components.
[0005] This utility model provides the following technical solution: a lifting device for installing prefabricated components of assembled buildings, including an upper lifting frame. Four fixing rings are evenly fixedly installed on the upper part of the upper lifting frame. Pull ropes are fixedly connected to each fixing ring, and connecting seats are fixedly connected to the ends of the four pull ropes away from the fixing rings. A fixing box is fixedly installed in the middle of the upper lifting frame. A servo motor is fixedly installed inside the fixing box. A transmission gear roller is fixedly sleeved on the output shaft of the servo motor, and a transmission gear belt meshes with the outer edge of the transmission gear roller. A transmission toothed belt engages with a second transmission toothed roller at its left end. A rotating shaft is fixedly sleeved in the middle of the second transmission toothed roller. The rotating shaft is movably sleeved with the bottom of the inner cavity of the fixed box. A lower lifting frame is provided below the upper lifting frame. A fixing plate is fixedly installed in the middle of the inner cavity of the lower lifting frame. The upper part of the fixing plate is fixedly connected to the bottom end of the rotating shaft. The horizontal angle of the lower lifting frame is adjusted by a servo motor to improve the flexibility of the device during the lifting process, facilitate the adjustment of the installation angle of the lifted components, meet different assembly requirements, shorten the assembly time, and effectively improve the assembly rate of prefabricated components.
[0006] Preferably, the left and right parts of the fixed plate are each movably connected to a push rod one via a shaft, and there are four push rods one in total, which are symmetrically distributed. The front and rear parts of the inner cavity of the lower hanging frame are each movably connected to a hydraulic rod one via a shaft, and there are four hydraulic rods one in total. The extension and retraction of the extension and retraction of the hydraulic rods are used to drive the push rod one to swing, so that the sliding plate moves in the left and right direction in the inner cavity of the lower hanging frame.
[0007] Preferably, the end of the push rod one away from the fixed plate is movably connected to the push rod two via a shaft. The left and right parts of the inner cavity of the lower hanging frame are respectively movably connected to sliding plates. The inner cavity of the sliding plates is provided with sliding grooves in the front and rear parts respectively. The inner cavity of the sliding plates is fixedly installed with a servo motor two. The output shaft of the servo motor two is fixedly sleeved with a helical gear one. The servo motor two drives the helical gear one to rotate. The meshing of the helical gear one and the helical gear two drives the threaded rod to rotate. During the rotation of the threaded rod, the slider slides in the sliding groove in the front and rear direction.
[0008] Preferably, a second helical gear is externally engaged with the first helical gear, and a threaded rod is fixedly sleeved in the middle of the second helical gear. The threaded rod is movably sleeved with a sliding groove, and the threads in the two sliding grooves are opposite. A slider is movably connected in the sliding groove, and the slider is movably sleeved with the threaded rod. A lifting rope is fixedly installed at the bottom of the slider, and a hook is fixedly installed at the bottom end of the lifting rope. By adjusting the position of the lifting rope and the hook, it is convenient for the device to lift components of different sizes, enhancing the applicability of the device. It also helps to keep the lifting rope and the lifting point perpendicular, ensuring the stability of the device when lifting prefabricated components.

[0010] 1. The servo motor drives the first transmission toothed roller to rotate, and the meshing of the transmission toothed belt drives the second transmission toothed roller to rotate, so that the rotating shaft drives the fixed plate to rotate, thereby adjusting the angle of the lower lifting frame in the horizontal direction.

The servo motor two drives helical gear one to rotate, and the meshing of helical gear one and helical gear two drives the threaded rod to rotate. During the rotation of the threaded rod, the slider moves in the slide groove in the front and back direction, thereby adjusting the position of the lifting rope and the hook, so that the hook is located at the lifting point of the component, realizing the connection between the component and the hook. This facilitates the lifting of components of different sizes and enhances the applicability of the device. It also helps to keep the lifting rope and the lifting point perpendicular, ensuring the stability of the device when lifting prefabricated components. Attached Figure Description

The upper part of the fixed plate 12 is fixedly connected to the bottom end of the rotating shaft 10. The connecting seat 4 is connected to the crane by bolts. The crane drives the entire device to move flexibly. After the crane lifts the component and moves it to the assembly position, the servo motor 6 drives the transmission toothed roller 7 to rotate. The meshing of the transmission toothed belt 8 drives the transmission toothed roller 9 to rotate, so that the rotating shaft 10 drives the fixed plate 12 to rotate, thereby adjusting the angle of the lower lifting frame 11 in the horizontal direction.

The component slides backward to adjust the position of the lifting rope 23 and the hook 24, so that the hook 24 is located at the lifting point of the component, which facilitates the connection between the component and the hook 24. Then, the component is lifted and moved to the assembly location by the crane. The servo motor 6 is turned on to drive the transmission toothed roller 7 to rotate. The meshing of the transmission toothed belt 8 drives the transmission toothed roller 9 to rotate, so that the rotating shaft 10 drives the fixed plate 12 to rotate, thereby adjusting the angle of the lower lifting frame 11 in the horizontal direction, which facilitates the orientation adjustment of the lifted component and meets different assembly angle requirements.
