[0002] Prefabricated buildings are a type of structure that uses machinery to install various reinforced concrete prefabricated components and assembles them according to design requirements. Prefabricated buildings often involve the lifting of various prefabricated components during construction. Prefabricated components mainly include wall panels, composite panels, balconies, stairs, prefabricated beams, prefabricated columns, etc. All prefabricated components are pre-buried with lifting rings during prefabrication.

[0003] For components such as composite panels, stairs and balconies, the horizontal plane needs to be level during installation to ensure smooth installation; for components such as wall panels, prefabricated beams and prefabricated columns, the vertical plane needs to be vertical during installation to ensure smooth installation. However, since some prefabricated components are not completely symmetrical structures, the center of gravity has a certain offset, which makes them prone to tilting during hoisting. Currently, it is only possible to adjust the state of the hoisting components on the hoisting device and observe them with the naked eye to make the corresponding planes of the above prefabricated components roughly horizontal or vertical. After hoisting to the designated position, the staff will manually adjust the prefabricated components to the appropriate state to facilitate installation.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] The following reference Figure 1-Figure 3 As shown, combined with a specific embodiment, this embodiment further illustrates that a lifting device for assembled prefabricated components is provided. Figure 1 As shown, it includes a hoisting frame 1, both sides of the bottom of the hoisting frame 1 are provided with support beams 2 that can slide along their own length direction, telescopic beams 21 are provided at both ends of the support beam 2, a hoisting assembly 3 is provided at one end of the telescopic beam 21 outside the support beam 2, and an indicating mechanism 4 is arranged in the middle of the support beam 2. When hoisting prefabricated components such as prefabricated stairs or prefabricated balconies that need to ensure the horizontality of the horizontal plane and whose center of gravity is not in the center position, the horizontality of the designated plane of the prefabricated component is indicated by the indicating mechanism 4, and then the state of the hoisting assembly 3 is adjusted to adjust the designated plane of the prefabricated component to a horizontal state, thereby ensuring the stability of the hoisting process and the accuracy of the position when hoisting to the installation point.

[0041] Reference Figure 1 , Figure 2 As shown, a sliding seat 22 is welded at the center of the top of the support beam 2, and a slide rail 11 is provided at the bottom of the hoisting frame 1 along its length direction. A positioning pin 221 is provided on the sliding seat 22, and a plurality of pin holes 111 for inserting the positioning pin 221 are distributed on the slide rail 11. The sliding seats 22 on both sides are slid at the same time according to the length of the prefabricated component to be hoisted, and the positioning pin 221 is inserted into the positioning hole at the corresponding position to realize the positioning of the sliding seat 22, so as to facilitate the adjustment of the position of the hoisting assembly 3 in the length direction of the hoisting frame 1, so as to facilitate the hoisting of prefabricated components of different lengths.

[0042] Reference Figure 2 As shown, telescopic electric cylinders 23 are provided on both sides of the bottom of the support beam 2, and a driving block 231 is fixedly connected to the piston rod of the telescopic electric cylinder 23, and the driving block 231 is fixedly connected to one end of the telescopic beam 21 located outside the support beam 2. The telescopic cylinder drives the driving block 231 to move, that is, the telescopic beam 21 can be moved inside or outside the support beam 2, thereby adjusting the position of the hoisting assembly 3 in the width direction of the hoisting frame 1, so as to facilitate the hoisting of prefabricated components of different widths.

[0043] The hoisting assembly 3 includes a hoisting motor 31, a hoisting plate 32 and a hoisting rope 33. A mounting seat 211 is welded on the telescopic beam 21. The hoisting plate 32 is rotatably connected in the mounting seat 211. The hoisting motor 31 is fixedly mounted on the mounting seat 211 and the output shaft of the hoisting motor 31 is fixedly connected to the hoisting plate 32. The hoisting rope 33 is wound on the hoisting plate 32, and the bottom end of the hoisting rope 33 is provided with a hook 331. After a plurality of hooks 331 are hoisted to the hoisting rings at corresponding positions on the prefabricated component, the hoisting motor 31 at the designated position is started to drive the hoisting plate 32 to rotate, that is, the hoisting rope 33 can be wound on the hoisting plate 32, so that the bottom end of the hoisting rope 33 drives the hook 331 to pull the hoisting ring on the prefabricated component to adjust the prefabricated component to an appropriate state. Since the multiple groups of hoisting assemblies 3 are independent of each other, the height of each hoisting position can be accurately adjusted respectively, so as to facilitate the corresponding plane on the prefabricated component to be in a horizontal state.

[0044] Reference Figure 1 , Figure 3 As shown, the indicating mechanism 4 includes a support frame 41, which is fixedly installed at the center position of the top surface of the supporting beam 2, an indicating rope 42 is suspended on the support frame 41, an indicating ball 43 is provided at the end of the indicating rope 42 away from the support frame 41, and a moving component 44 for moving the indicating rope 42 away from the supporting beam 2 is provided on one side of the supporting beam 2; the moving component 44 includes a moving electric cylinder 441, a moving block 442 is provided on the piston rod of the moving electric cylinder 441, a guide pulley 443 is provided on the moving block 442, and the indicating rope 42 is mounted on the guide pulley 443. After adjusting the prefabricated components such as prefabricated stairs or prefabricated balconies to the specified state through the lifting component 3, the position of the guide pulley 443 can be changed by moving the piston rod of the mobile electric cylinder 441 into the cylinder barrel, thereby changing the height of the bottom end of the indicator rope 42, so that the indicator ball 43 falls to contact the specified plane on the prefabricated component. When the specified plane on the prefabricated component is tilted, the indicator ball 43 will roll, and the staff can determine the tilt direction of the specified plane on the prefabricated component according to the rolling direction of the indicator ball 43, thereby adjusting the state of the lifting component 3 at the corresponding position. After the adjustment is completed, the horizontality of the specified plane on the prefabricated component is judged by observing whether the indicator ball 43 rolls again, until the indicator ball 43 no longer rolls, that is, it can be determined that the specified plane on the prefabricated component has been adjusted to a horizontal state, so as to ensure the accuracy of the position of the prefabricated component during installation.

[0045] Reference Figure 3As shown, in order to prevent the indicator rope 42 from falling off the guide pulley 443 when the indicator ball 43 rolls on the specified plane of the prefabricated component, a limiting pulley 444 is further configured on the side of the guide pulley 443 away from the moving block 442. The indicator rope 42 is clamped between the limiting pulley 444 and the guide pulley 443 and will never be completely separated from the guide pulley 443, thereby ensuring the reliability of the indicator rope 42.

[0046] Reference Figure 3 As shown, the outer sleeve of the indicator ball 43 is provided with a flexible ball sleeve 431. In this embodiment, the flexible ball sleeve 431 is made of rubber material and has a large friction force. A plurality of convex points 432 are evenly distributed on the flexible ball sleeve 431 to further increase the friction force between the indicator ball 43 and the prefabricated component, so that the indicator ball 43 will roll only when the plane specified on the prefabricated component reaches a certain inclination angle, and the indicator ball 43 will not roll within the allowable error range. The number and size of the convex points 432 on the flexible ball sleeve 431 will also affect the friction coefficient of the flexible ball sleeve 431. Therefore, replacing the flexible ball sleeve 431 with a different number of convex points 432 or a different size of convex points 432 can adapt to different allowable error ranges of prefabricated components.

[0047] This embodiment also provides a hoisting method using the hoisting device of the assembled prefabricated component, comprising the following steps:

[0048] S1. Adjust the positions of the support beams 2 on both sides on the hoisting frame 1 according to the length of the prefabricated component to be hoisted;

[0049] S2. Adjust the position of the telescopic beam 21 on the support beam 2 according to the width of the prefabricated component to be hoisted;

[0050] S3, hang the hook 331 of the hoisting assembly 3 on the hoisting ring of the prefabricated component, and lift the hoisting frame 1 upward to the ground through external hoisting equipment such as a tower crane or a gantry crane;

[0051] S4, adjusting the position of the indicator ball 43 by the toggle assembly so that the indicator ball 43 contacts the designated plane on the prefabricated component, and observing the state of the indicator ball 43 on the designated plane;

[0052] S5. When the indicator ball 43 rolls, the state of the hoisting assembly 3 at the corresponding position is adjusted to raise or lower the height of the corresponding position until the indicator ball 43 stops rolling, and it is determined that the designated plane on the prefabricated component has been adjusted to a horizontal state;

[0053] S6. Continue to hoist the hoisting frame 1 to the designated installation position using external hoisting equipment.

[0054] Embodiment 2

[0055] The following reference Figure 4-Figure 9 As shown, further explained in combination with a specific embodiment, the difference between this embodiment and the first embodiment is that this embodiment is used to hoist a prefabricated wall panel with an offset center of gravity, and it is necessary to indicate the verticality of the wall surface on the prefabricated wall. Figure 4 , Figure 5 As shown, this embodiment also includes an auxiliary indicator 5, which includes a support rod 51 and an indicator rod 52. The support rod 51 is vertically welded to the support frame 41, and the top end of the indicator rod 52 is hinged on the support rod 51 and the bottom end is vertically facing the ground.

[0056] Reference Figure 5 , Figure 6 As shown, the support rod 51 includes a first support rod 511 and a second support rod 512 . The first support rod 511 is welded to one side of the support frame 41 , and the second support rod 512 is slidably connected to the first support rod 511 . A connecting column 513 is provided between the second support rod 512 and the moving block 442 .

[0057] Start the moving electric cylinder 441 and move the piston rod of the moving electric cylinder 441 into the cylinder barrel, so that the moving block 442 drives the guide pulley 443 and the second support rod 512 to move toward the hanging frame 1 at the same time, until the bottom end of the indicator rod 52 contacts the prefabricated wall, so that the indicator rod 52 rotates to a tilted state under the abutment of the prefabricated wall; then move the piston rod of the moving electric cylinder 441 out of the cylinder barrel, so that the moving block 442 drives the guide pulley 443 and the second support rod 512 to move toward the hanging frame 1 at the same time, so that the indicator rod 52 is separated from the prefabricated wall. Figure 7 As shown, if the bottom end of the indicator rope 42 is still in a vertical state after the indicator rod 52 is rotated to the inclined state, the wall surface of the prefabricated wall is in a state of being inclined toward the hanging frame 1 from top to bottom; Figure 8 As shown, if the indicator rod 52 is rotated to the inclined state, the indicator rope 42 is also in the inclined state, and when the indicator rod 52 is rotated back to the vertical state, the indicator rope 42 is also in the vertical state, then the wall surface of the prefabricated wall is in the vertical state; refer to Fig. 9 As shown, if the indicator rope 42 is still in an inclined state after the indicator rod 52 rotates back to the vertical state, the wall surface of the prefabricated wall is in an inclined state toward the outside of the hanging frame 1 from top to bottom.

[0058] Reference Figure 6As shown, the indicator rod 52 includes a top rod 521 and two fork arms 522. The top rod 521 is hingedly arranged at one end of the second support rod 512 outside the first support rod 511. The two fork arms 522 are arranged on both sides of the bottom of the top rod 521 and have a gap 523. The indicator rope 42 is located between the gaps 523 of the two fork arms 522, so that the staff can observe whether the indicator rope 42 and the fork arms 522 are in a state of being parallel to each other on the ground. Both fork arms 522 are provided with indicator grooves 5221 along their length direction. The width of the indicator grooves 5221 is consistent with the diameter of the indicator rope 42. By observing whether the portion of the indicator rope 42 located in the fork arms 522 overlaps with the indicator grooves 5221, it is possible to conveniently and accurately judge whether the indicator rope 42 and the indicator rod 52 are in a state of being parallel to each other.
