Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction equipment, more particularly, to a hoisting device for prefabricated components of fabricated buildings. BACKGROUND

[0002] Fabricated buildings refer to various prefabricated components of buildings such as outer wall panels, inner wall panels, laminated panels, balconies, air conditioning panels, staircases, prefabricated beams, and prefabricated columns, which are prefabricated and formed in a factory workshop and then transported to a construction site for installation. Since the prefabricated components are prefabricated in the same workshop, the dimensions and structures of the prefabricated components are more accurate, and only installation is performed at the construction site, greatly reducing the on-site construction work, making the on-site construction simpler, and omitting the maintenance process of on-site pouring, thereby greatly shortening the construction period.

[0023] Compared with the prior art, the hoisting device for prefabricated components of assembled buildings provided in this application achieves at least the following beneficial effects:

[0024] In this application, the hoisting device includes a ring frame, multiple lifting components, and a rotating component. Each lifting component includes a slider assembly, a lifting mechanism, and a lifting ring rod. External hoisting equipment directly lifts the ring frame via ropes. The ring frame has a second cavity and a passage hole. The slider assembly is installed in the second cavity, and the lifting ring rod is installed on the slider assembly. The bottom end of the lifting ring rod passes through the passage hole, and the bottom end of the lifting ring rod is directly connected to the precast component via ropes. The lifting mechanism can drive the lifting ring rod to move up and down, and the lifting ring rod can drive a part of the precast component to move up and down via ropes, causing the angle between the precast component and the horizontal plane to change, thereby allowing the precast component to adapt to the tilt angle of the exterior wall to which the precast component is to be installed. A rotating drive motor... The mechanism can drive the driven gear to rotate. Because the outer gear ring meshing with the driven gear is fixedly installed in the first cavity and remains stationary relative to the annular frame, when the rotation drive mechanism drives the driven gear to rotate, the driven gear cannot convert the rotational kinetic energy into the rotation of the outer gear ring. Instead, the kinetic energy is converted into the rotation of the driven gear itself and its revolution around the outer gear ring. The slider assembly is slidably connected to the side wall of the second cavity. Therefore, the revolution of the driven gear also drives the slider assembly, connecting frame, and rotation drive mechanism to rotate around the outer gear ring. The lifting ring rod installed on the slider assembly is also driven to rotate around the outer gear ring, allowing the precast component to rotate on the horizontal plane. This allows the precast component to adapt to the angular position of the exterior wall surface on the horizontal plane. In summary, the hoisting device provided in this embodiment can adjust the angle between the precast component and the horizontal plane, and also adjust the angular position of the precast component on the horizontal plane. This enables the precast component to adapt to the installation of exterior wall panels at various angles, improving the installation efficiency and construction safety of the precast component.

[0045] Please refer to Figures 1 to 8 This application provides a hoisting device for prefabricated components of prefabricated buildings, including a ring frame 100, multiple lifting components and rotating components.

[0046] The annular frame 100 is horizontally arranged, and its top side is connected to external hoisting equipment. The annular frame 100 has an annular mounting cavity 110 and a passage hole 114. The mounting cavity 110 includes a first cavity 111, a second cavity 112 and a third cavity 113 arranged sequentially from the center outward. The passage hole 114 is located on the bottom side of the annular frame 100 and communicates with the second cavity 112. An external gear ring 120 is fixedly installed in the first cavity 111 and is coaxial with the annular frame 100.

[0047] Each lifting assembly includes a slider group 210, a lifting mechanism, and a lifting ring rod 230. The slider group 210 is installed in the second cavity 112 and is slidably connected to the side wall of the second cavity 112. The bottom end of the lifting ring rod 230 passes through the passage hole 114. Both the lifting ring rod 230 and the lifting mechanism are installed in the slider group 210. The lifting mechanism is used to drive the lifting ring rod 230 to move up and down. The bottom end of the lifting ring rod 230 is used to connect with the precast component 00.

[0048] Each rotating assembly includes a driven gear 310, a rotation drive mechanism, and a connecting frame 322. The axis of the driven gear 310 is perpendicular to the horizontal plane. The connecting frame 322 is slidably mounted on the third cavity 113 and is fixedly connected to the slider assembly. The rotation drive mechanism is mounted on the connecting frame 322 and is used to drive the driving gear 321 to rotate. The driven gear 310 is rotatably connected to the slider assembly 210, and the external gear ring 120 meshes with the driven gear 310.

[0049] In one specific embodiment, the prefabricated component 00 is a rectangular planar structural component. The number of lifting components and rotating components is the same, which is four in total. The outer wall to which the prefabricated component 00 is to be installed is an inclined roof wall. The roof wall has an angle α with the horizontal plane. After the prefabricated component 00 is lifted, there is an angle β between the prefabricated component 00 and the roof wall on the horizontal plane.

[0050] The following will use the above specific implementation method as an example to illustrate the usage process of this hoisting device:

[0051] See Figure 1As shown, external hoisting equipment directly lifts the ring frame 100 via ropes, and the bottom ends of the lifting rings 230 of the four lifting mechanisms directly lift the precast components 00 via ropes. When it is necessary to adjust the tilt angle of the precast components 00 with respect to the horizontal plane, some lifting mechanisms are activated. The lifting mechanisms drive the corresponding lifting rings 230 to move downwards. The lifting rings 230 drive the corresponding parts of the precast components 00 downwards via ropes, while the other parts of the precast components 00 remain fixed, causing the precast components 00 to tilt. The lifting rings 230 continue to drive the corresponding parts of the precast components 00 downwards via ropes until the angle between the precast components 00 and the horizontal plane reaches approximately α. At this point, the lifting mechanisms stop. The precast components 00 can adapt to the tilt angle of the roof and walls, facilitating the installation of the precast components 00. When the angular position of the prefabricated component 00 on the horizontal plane needs to be adjusted, the rotation drive mechanisms of the four rotating components are activated. In each rotating component, the rotation drive mechanism drives the driven gear 310 to rotate. The outer gear ring 120, which meshes with the driven gear 310, remains stationary relative to the annular frame 100, causing the driven gear 310 to rotate on its own axis and around the axis of the outer gear ring 120. At the same time, the rotating driven gear 310 also drives the slider assembly 210, the connecting frame 322, and the rotation drive mechanism to rotate around the axis of the outer gear ring 120. Because the lifting ring rod 230 is installed on the slider assembly 210, the lifting ring rods 230 of the four rotating components will also be driven to rotate around the axis of the external gear ring 120. The four lifting ring rods 230 drive the precast component 00 to rotate on the horizontal plane, causing the angle between the precast component 00 and the roof wall to gradually decrease on the horizontal plane until the angle between the precast component 00 and the roof wall is basically zero. At this point, the four rotating components stop, and the precast component 00 can adapt to the angular position of the roof cavity surface on the horizontal plane. After the precast component 00 is adjusted, the external hoisting equipment lowers the precast component 00 to the plane where the roof wall is located, and then performs the fixed installation between the precast component 00 and the roof wall. In specific implementation, the external hoisting equipment can first lower the precast component 00 to a plane close to the roof wall, and then restart the lifting assembly to make the four corners of the precast component 00 simultaneously and synchronously lower in a small range until it is on the plane where the roof wall is located. It should be noted that during construction, any one or two adjustment processes can be freely selected according to the specific hoisting conditions and needs. When both the horizontal tilt angle and the angular position of the precast component 100 on the horizontal plane need to be adjusted, there is no specific order to these two adjustment processes. That is, the tilt angle of the precast component 00 on the horizontal plane can be adjusted first, followed by the angular position of the precast component 00 on the horizontal plane, or the angular position of the precast component 00 on the horizontal plane can be adjusted first, followed by the tilt angle of the precast component 00 on the horizontal plane. These two adjustment processes can also be repeated and interleaved. The specific construction should be carried out in a free combination and selection according to the needs.

[0052] In this embodiment, the hoisting device includes a ring frame 100, multiple lifting components, and a rotating component. Each lifting component includes a slider assembly 210, a lifting mechanism, and a lifting ring rod 230. External hoisting equipment directly lifts the ring frame 100 via ropes. The ring frame 100 has a second cavity 112 and a passage hole 114. The slider assembly 210 is installed in the second cavity 112, and the lifting ring rod 230 is installed on the slider assembly 210. The bottom end of the lifting ring rod 230 passes through the passage hole 114, and the bottom end of the lifting ring rod 230 is directly connected to the precast component 00 via ropes. The lifting mechanism can drive the lifting ring rod 230 to move up and down. The lifting ring rod 230 can drive a part of the precast component 00 to move up and down via ropes, causing the angle between the precast component 00 and the horizontal plane to change, thereby allowing the precast component 00 to adapt to the tilt angle of the exterior wall to which the precast component 00 is to be installed. The rotating drive mechanism can... The driven gear 310 is able to rotate. Since the outer gear ring 120, which meshes with the driven gear 310, is fixedly installed in the first cavity 111 and is stationary relative to the annular frame 100, when the rotation drive mechanism drives the driven gear 310 to rotate, the driven gear 310 cannot convert the rotational kinetic energy into the rotation of the outer gear ring 120. Instead, the kinetic energy is converted into the rotation of the driven gear 310 and its revolution around the outer gear ring 120. The slider assembly 210 is slidably connected to the side wall of the second cavity 112. Therefore, the revolution of the driven gear 310 also drives the slider assembly 210, the connecting frame 322, and the rotation drive mechanism to rotate around the outer gear ring 120. The lifting ring rod 230 installed in the slider assembly 210 is also driven to rotate around the outer gear ring 120, so that the precast component 00 can rotate on the horizontal plane, thereby enabling the precast component 00 to adapt to the angular position of the exterior wall surface on the horizontal plane. In summary, the hoisting device provided in this embodiment can adjust the angle between the prefabricated component 00 and the horizontal plane, and can also adjust the angular position of the prefabricated component 00 on the horizontal plane, thereby enabling the prefabricated component 00 to adapt to the installation of exterior wall panels at various angles, improving the installation efficiency and construction safety of the prefabricated component 00.

[0053] See Figure 4 and Figure 5 In some embodiments, the rotation drive mechanism includes a drive gear 321 and a rotation motor. Both the drive gear 321 and the rotation motor are mounted on the connecting frame 322. The rotation motor drives the drive gear 321 to rotate, and the drive gear 321 meshes with the driven gear 310.

[0054] In the specific implementation of the embodiment, after the rotation drive mechanism is started, the rotation motor drives the drive gear 321 to rotate, and then the drive gear 321 drives the driven gear 310 meshing with it to rotate.

[0055] See Figure 6 and Figure 7In some embodiments, the lifting mechanism includes a screw 221, a lifting gear, and a lifting motor. The lifting motor drives the lifting gear to rotate. The lifting gear meshes with the screw 221, and the bottom end of the screw 221 is connected to the lifting ring rod 230.

[0056] In this embodiment, the lifting motor can drive the lifting gear to rotate, and the lifting gear drives the screw 221 to move up and down along its own axis, so that the screw 221 can drive the lifting ring rod 230 to move up and down.

[0057] See Figure 6 and Figure 7 In some embodiments, the slider assembly 210 has a through hole, the screw 221 passes through the through hole and is slidably connected to the side wall of the through hole, and the driven gear 310 passes through the screw 221 and is clearance-fitted with the screw 221.

[0058] See Figure 6 and Figure 7 In some embodiments, the slider assembly 210 includes a first slider 211 and a second slider 212. The upper sidewall of the first cavity 111 is provided with a first sliding groove, and the first slider 211 is engaged with and slidably connected to the first sliding groove. The lower sidewall of the first cavity 111 is provided with a second sliding groove, and the second slider 212 is engaged with and slidably connected to the second sliding groove. The through hole includes a first through hole 2011 and a second through hole 2012. The first through hole 2011 is disposed in the first slider 211, and the second through hole 2012 is disposed in the second slider 212. The screw 221 passes through the first through hole 2011 and the second through hole 2012, and the screw 221 is slidably connected to the sidewalls of the first through hole 2011 and the second through hole 2012. Along the vertical direction, the driven gear 310 is located between the first slider 211 and the second slider 212.

[0059] In this embodiment, the slider group 210 includes a first slider 211 and a second slider 212, which can limit the passive gear 310 in the vertical direction.

[0060] See Figure 6 In some embodiments, an assembly ring 330 is provided between the driven gear 310 and the screw 221; the slider assembly 210 has an assembly blind hole 202, and the end of the assembly ring 330 in the up-down direction is engaged with the assembly blind hole 202; the screw 221 is clearance-fitted with the assembly ring 330, and the driven gear 310 is fixedly sleeved on the outer circumferential surface of the assembly ring 330.

[0061] In this embodiment, the assembly ring 330 prevents the driven gear 310 from contacting the screw 221, thus preventing the movement of the screw 221 from affecting the driven gear 310. The bottom and side walls of the assembly blind hole 202 can limit the movement of the assembly ring 330, ensuring that the assembly ring 330 does not collide with the screw 221 during the movement of the slider assembly. This allows the assembly ring 330 to remain coaxial with the screw 221, further preventing the movement of the screw 221 from affecting the driven gear 310.

[0062] See Figure 1 and Figure 2 In some embodiments, the hoisting device further includes a central plate 400 and a connecting beam 500. The central plate is located at the center of the annular frame 100, and the central plate 400 and the annular frame 100 are fixedly connected by the connecting beam 500. A camera is installed on the bottom side of the central plate 400.

[0063] In this embodiment, the adjustment and installation of the prefabricated component 00 can be observed in real time through a camera device, reducing errors and safety issues caused by human observation, and improving the installation efficiency and construction safety of the prefabricated component 00.

[0064] See Figures 1 to 3 In some embodiments, a first connecting part 401 is provided on the top side of the central plate, and the first connecting part 401 is connected to an external hoisting device through a first hoisting rope 01; a second connecting part 402 is provided on the bottom side of the central plate, and the second connecting part 402 is connected to the prefabricated component 00 through a second hoisting rope 02.

[0065] See Figure 1 and Figure 2 In some embodiments, the top side of the annular frame 100 is provided with a third connecting part 101, which is connected to an external hoisting device via a third hoisting rope 03.

[0066] In practice, the first connecting part 40, the second connecting part 402 and the third connecting part 101 can all be set as lifting ring structures.
