Description

[0001] The present application relates to the technical field of construction equipment, and more specifically, to a hoisting device for prefabricated components of assembled buildings. Background Art

[0002] Prefabricated buildings refer to buildings in which various prefabricated components such as exterior wall panels, interior wall panels, composite panels, balconies, air conditioning panels, stairs, prefabricated beams, prefabricated columns, etc. are prefabricated and processed in the factory workshop, and then transported to the construction site for installation. Since each prefabricated component is prefabricated and formed in the same workshop, the size and structure of each prefabricated component are more accurate, and only installation is carried out on the construction site, which greatly reduces on-site construction work, makes on-site construction simpler, and omits the on-site pouring maintenance process, greatly shortening the construction period. However, various prefabricated components have a certain weight, and it is difficult to carry them to the installation location by hand, so they need to be hoisted and decorated.

[0045] Please refer to Figures 1 to 8 The embodiment of the present application provides a hoisting device for prefabricated components of an assembled building, including an annular frame 100, a plurality of lifting components and a rotating component.

[0046] Among them, the annular frame 100 is arranged horizontally, the top side of the annular frame 100 is connected to the external lifting equipment, the annular frame 100 is provided with an annular installation cavity 110 and a through hole 114, the installation cavity 110 includes a first cavity 111, a second cavity 112 and a third cavity 113 which are sequentially connected from the center of the ring to the outside, the through hole 114 is arranged on the bottom side of the annular frame 100, and the through hole 114 is connected to the second cavity 112, an outer gear ring 120 is fixedly installed in the first cavity 111, and the outer gear ring 120 is coaxial with the annular frame 100.

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

[0048] Each rotating assembly includes a passive gear 310, a rotating drive mechanism and a connecting frame 322. The axis of the passive gear 310 is arranged perpendicular to the horizontal plane. The connecting frame 322 is slidably installed in the third cavity 113, and the connecting frame 322 is fixedly connected to the sliding group. The rotating drive mechanism is installed on the connecting frame 322. The rotating drive mechanism is used to drive the active gear 321 to rotate. The passive gear 310 is rotatably connected to the slider group 210, and the outer gear ring 120 is meshed with the passive gear 310.

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

[0050] The following will take the above specific implementation as an example to illustrate the use process of the lifting device:

[0051] See also Figure 1As shown, the external hoisting equipment directly lifts the annular frame 100 through ropes, and the bottom ends of the lifting ring rods 230 of the four lifting mechanisms directly lift the prefabricated component 00 through ropes. When it is necessary to adjust the inclination angle of the prefabricated component 00 with the horizontal plane, part of the lifting drive mechanism is started, and the lifting drive mechanism drives the corresponding lifting ring rod 230 to move downward. The lifting ring rod 230 drives the corresponding part of the prefabricated component 00 to move downward through the rope, while the other parts of the prefabricated component 00 are fixed, so that the prefabricated component 00 is inclined, and the lifting ring rod 230 drives the corresponding part of the prefabricated component 00 to continue to move downward through the rope until the angle between the prefabricated component 00 and the horizontal plane basically reaches α, and the lifting drive mechanism stops. At this time, the prefabricated component 00 can adapt to the inclination angle of the roof wall, which facilitates the installation of the prefabricated component 00. When the angular position of the prefabricated component 00 in the horizontal plane needs to be adjusted, the rotation drive mechanisms of the four rotation assemblies are all started. In each rotation assembly, the rotation drive mechanism drives the passive gear 310 to rotate, and the outer gear ring 120 meshing with the passive gear 310 is stationary relative to the annular frame 100, so that the passive gear 310 rotates and rotates around the axis of the outer gear ring 120. At the same time, the rotating passive gear 310 also drives the slider group 210, the connecting frame 322 and the rotation drive mechanism to rotate around the axis of the outer gear ring 120. Because the eyelet rod 230 is installed on the slider group 210, the eyelet rods 230 of the four rotating components will also be driven to rotate around the axis of the outer gear ring 120, and the four eyelet rods 230 drive the prefabricated component 00 to rotate on the horizontal plane, so that the angle between the prefabricated component 00 and the roof wall on the horizontal plane gradually decreases until the angle between the prefabricated component 00 and the roof wall on the horizontal plane is basically zero, and the four rotating components stop. At this time, the prefabricated component 00 can adapt to the angular position of the roof cavity surface on the horizontal plane. After the prefabricated component 00 is adjusted, the external lifting equipment lowers the prefabricated component 00 to the plane where the roof wall is located, and then fixes the prefabricated component 00 and the roof wall. In specific implementation, the external lifting equipment can first lower the prefabricated component 00 to a plane close to the roof wall, and then start the lifting assembly again to make the four corners of the prefabricated component 00 simultaneously and synchronously descend 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 should be freely selected according to the specific lifting construction conditions and needs; when both the horizontal inclination angle and the angular position of the prefabricated component 100 in the horizontal plane need to be adjusted, there is no order of precedence in the specific implementation of these two adjustment processes, that is, the inclination angle of the prefabricated component 00 and the horizontal plane can be adjusted first, and then the angular position of the prefabricated component 00 in the horizontal plane can be adjusted, or the angular position of the prefabricated component 00 in the horizontal plane can be adjusted first, and then the inclination angle of the prefabricated component 00 and the horizontal plane can be adjusted. These two adjustment processes can also be repeated and interspersed with each other many times, and they should be freely matched and selected according to needs during specific construction.

[0052] In this embodiment, the lifting device includes an annular frame 100, a plurality of lifting components and a rotating component, wherein each lifting component includes a slider group 210, a lifting drive mechanism and a lifting ring rod 230, and the external lifting equipment directly lifts the annular frame 100 through a rope, and the annular frame 100 is provided with a second cavity 112 and a passage hole 114, and the slider group 210 is installed in the second cavity 112, and the slider group 210 is installed with a lifting ring rod 230, and the bottom end of the lifting ring rod 230 is penetrated through the passage hole 114, and the bottom end of the lifting ring rod 230 is directly connected to the prefabricated component 00 through a rope; the lifting drive mechanism can drive the lifting ring rod 230 to move up and down, and the lifting ring rod 230 can drive part of the prefabricated component 00 to move up and down through the rope, so that the angle between the prefabricated component 00 and the horizontal plane changes, so that the prefabricated component 00 can adapt to the inclination angle of the external wall surface where the prefabricated component 00 is to be installed; the rotating drive mechanism The structure can drive the passive gear 310 to rotate, because the outer ring gear 120 meshing with the passive gear 310 is fixedly installed in the first cavity 111, and the outer ring gear 120 is stationary relative to the annular frame 100. Therefore, when the rotating drive mechanism drives the passive gear 310 to rotate, the passive gear 310 cannot convert the rotational kinetic energy into the rotation of the outer ring gear 120. The kinetic energy will be converted into the self-rotation of the passive gear 310 and the revolution around the outer ring gear 120, and the slider group 210 is slidingly connected to the side wall of the second cavity 112. Therefore, the revolution of the passive gear 310 also drives the slider group 210, the connecting frame 322 and the rotating drive mechanism to rotate around the outer ring gear 120, and the eye rod 230 installed on the slider group 210 is also driven to rotate around the outer ring gear 120, so that the prefabricated component 00 can rotate on the horizontal plane, so that the prefabricated component 00 can adapt to the angular position of the outer wall surface in the horizontal plane. In summary, the lifting 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 in the horizontal plane, thereby enabling the prefabricated component 00 to adapt to the installation of exterior wall panels at various angles, thereby improving the installation efficiency and construction safety of the prefabricated component 00.
