[0044] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0045] like Figures 1 to 8As shown, the lifting and positioning equipment for assembled prefabricated components provided in the embodiment of the present application includes a lifting plate 1, a controller 2, a center of gravity adjustment mechanism 3, an auxiliary lifting mechanism 4 and an inclination adjustment mechanism 5. Among them, the lifting plate 1 is used to be connected to the lifting equipment, and the lifting plate 1 is provided with a controller 2, and the controller 2 is connected to the center of gravity adjustment mechanism 3, the auxiliary lifting mechanism 4 and the inclination adjustment mechanism 5, and is used to control the operation of the center of gravity adjustment mechanism 3, the auxiliary lifting mechanism 4 and the inclination adjustment mechanism 5. The center of gravity adjustment mechanism 3 is arranged at the bottom of the lifting plate 1, and is used to adjust the center of gravity of the prefabricated component during the lifting process. The auxiliary lifting mechanism 4 is arranged below the center of gravity adjustment mechanism 3, and is used to lift and lower the prefabricated component during the lifting process. The inclination adjustment mechanism 5 is connected to the prefabricated component and is used to adjust the verticality of the prefabricated component to the installation surface during installation and assembly.

[0046] The shape of the lifting plate 1 can be designed according to the shape of the prefabricated component during lifting. This embodiment takes the lifting and positioning of the prefabricated column 10 as an example, so the appearance shape of the lifting plate 1 is designed to be square to facilitate installation and use during lifting.

[0047] In some specific embodiments, such as Figure 4 As shown, a plurality of first lifting rings 11 can be evenly spaced on the top surface of the lifting plate 1. The first lifting ring 11 is used to connect to the lifting rope or hook of the lifting equipment, and its shape can be set to circular, elliptical, semi-elliptical, or other shapes that are convenient for installation and locking. In the embodiment of the present application, the first lifting ring 11 is preferably semi-circular. The semi-circular structure makes the first lifting ring 11 more evenly stressed during lifting, which can prevent deformation during lifting.

[0048] In the embodiments of this application, Figure 4 As shown, there are five first lifting rings 11, specifically, four first lifting rings 11 are evenly arranged along the circumference of the lifting plate 1, and one first lifting ring 11 is arranged at the center of the lifting plate 1. The lifting and positioning equipment of the present application can be transported by different first lifting rings 11 under different usage conditions. For example, when the lifting and positioning equipment of the present application is lifted from a high place to a low place without load, only one first lifting ring 11 located at the center of the lifting plate 1 can be used for lifting. When lifting prefabricated components, four first lifting rings 11 evenly arranged along the circumference of the lifting plate 1 can be used for lifting to ensure efficient operation under the premise of safety.

[0049] The first lifting ring 11 is connected to the lifting plate 1 through the lifting column 12. Specifically, the first lifting ring 11 is fixedly connected to one end of the lifting column 12, and a thread is provided on the outer wall of the other end of the lifting column 12. A threaded hole is provided at a position corresponding to the lifting column 12 on the lifting plate 1, and the other end of the lifting column 12 is screwed into the threaded hole. The lifting column 12 and the lifting plate 1 are then reinforced by welding to prevent the thread from loosening during use and causing a safety accident.

[0050] In the embodiments of this application, Figure 4 As shown, a mobile power supply 6 is also provided on the top of the lifting plate 1. The mobile power supply 6 is connected to the controller 2 and is used to provide power to the controller 2. The mobile power supply 6 is internally provided with a battery and a conversion circuit.

[0051] Specifically, the controller 2 includes a control module and a signal transceiver module, and the control module performs wireless communication with an external mobile terminal through the signal transceiver module.

[0052] In a specific embodiment, Figure 7 and Figure 8 As shown, the center of gravity adjustment mechanism 3 includes a drive assembly (not shown in the figure), a slide 31, a slider 32 and a screw 33. Among them, on the lower surface of the lifting plate 1, along the circumference of the lifting plate 1, two or more slides 31 are evenly spaced outward from the bottom center of the lifting plate 1. For example, four centrally symmetrical slides 31 are provided on the lower surface of the lifting plate 1. Along the length direction of the slide 31, a screw 33 is provided in the slide 31, and the two ends of the screw 33 are respectively rotatably connected to the side wall of the lifting plate 1 at the slide 31. A slider 32 is provided on the screw 33, and the slider 32 is connected to the auxiliary lifting mechanism 4. The drive assembly is connected to the controller 2 and the screw 33, which is used to drive the screw 33 to rotate.

[0053] Specifically, a first through hole 321 is defined in the slider 32 , a spiral structure is provided on the wall surface of the slider 32 in the first through hole 31 , and the slider 32 is matched and connected to the lead screw 33 via the spiral structure.

[0054] The driving assembly includes an electric motor and a gear, wherein the electric motor is arranged on the lower surface of the lifting plate 1 and is electrically connected to the controller 2. A gear is provided at one end of the lead screw 33, and the output shaft of the electric motor adopts a gear shaft meshing with the gear.

[0055] When the controller 2 controls the electric motor to rotate, the electric motor drives the screw 33 to rotate, so that the slider 32 moves to the desired position, and then the center of the prefabricated component connected to the slider 32 through the auxiliary lifting mechanism 4 is adjusted to below the center of the lifting plate 1, ensuring the safety and stability of the prefabricated component during the lifting process.

[0056] In a specific embodiment, Figures 5 to 8 As shown, the auxiliary lifting mechanism 4 includes a tension sensor 41, a first electric hoist 42, and a first screw 43. The tension sensor 41 is fixedly connected to the end surface of the slider 32 located outside the chute 31. The first electric hoist 42 is fixedly connected to the end of the tension sensor 41 opposite the end connected to the slider 32. Both the tension sensor 41 and the first electric hoist 42 are connected to the controller 2. A suspension rope 421 is provided in the first electric hoist 42, and the protruding end of the suspension rope 421 is connected to the first screw 43, which is used to securely connect to the prefabricated component.

[0057] The tension sensor 41 is used to detect the tension value generated by the prefabricated component during the lifting process, and transmit the tension value to the controller 2, which controls the rotation of the electric motor according to the tension value.

[0058] Specifically, a second lifting ring is provided on the first screw rod 43 , and the extended end of the lifting rope 421 is connected to the second lifting ring.

[0059] In a specific embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the inclination adjustment mechanism 5 includes a second electric winch 51 , a positioning block 52 , a pulley 53 , a core shaft 54 ​​, an inclinometer 55 , a fixing assembly 56 and a locking assembly 57 .

[0060] The second electric hoist 51 is mounted on the lifting plate 1 and includes a pull rope 511. Specifically, the second electric hoist 51 can be mounted on the top surface of the lifting plate 1. Multiple second through-holes 13 are evenly spaced around the circumference of the lifting plate 1. Preferably, the number of second through-holes 13 is an even number. The pull rope 511 is fixedly connected to the second electric hoist 51 at its fixed end. Its extended end, after passing through the second through-hole 13, is connected to the installation location of the prefabricated component via a fixing assembly 56.

[0061] Positioning block 52 is equipped with a pulley 53. A core shaft 54 ​​is rotatably connected to the center of pulley 53. The ends of core shaft 54 ​​are fixedly connected to the opposite side walls of positioning block 52. A pull cord 511 loops around pulley 53 and then extends diagonally outward from the center of positioning block 52. Positioning block 52 also includes a locking assembly 57, which restricts the rotation of pulley 53 and the sliding of pull cord 511.

[0062] A high-precision inclinometer 55 is fixedly provided on the inner wall of the positioning block 52 parallel to the core shaft 54 ​​. The inclinometer 55 is used to detect the tilt of the positioning block 52 and convert the detected tilt into an electrical signal and transmit it to the controller 2 .

[0063] The positioning block 52 is detachably mounted on the side wall of the prefabricated component by means of bolts 521 , wherein the bolts 521 and the inclinometer 55 are arranged on the same inner wall of the positioning block 52 .

[0064] Specifically, if Figure 1 and Figure 2 As shown, the fixing assembly 56 includes a fixing block 561, a second screw 562 and a nut 563. The extended end of the pull rope 511 is connected to the fixing block 561 through a lock buckle, and the fixing block 561 is detachably connected to the installation position of the prefabricated component through the second screw 562 and the nut 563.

[0065] Specifically, if Figure 6 As shown, the locking assembly 57 includes a block 571, a spring 572, an electric telescopic rod 573, an upper long link 574, a lower long link 575, and a short link 576. The block 571 is positioned on the side of the pulley 53 away from the inclinometer 55. Several springs 572 are disposed between the side of the block 571 away from the pulley 53 and the inner wall of the positioning block 52. The upper end of the block 571, which is closer to the pulley 53, is hingedly connected to the upper long link 574, and the lower end is hingedly connected to the lower long link 575. The upper long link 574 and the lower long link 575 are symmetrically arranged. A short link 576 is disposed between the upper long link 574 and the lower long link 575, with its ends hingedly connected to the upper long link 574 and the lower long link 575, respectively. An electric telescopic rod 573 is provided on the side of the short connecting rod 576 away from the clamping block 571. One end of the electric telescopic rod 573 is fixedly connected to the inner wall of the positioning block 52 where the inclinometer 55 is located, and the other end is hingedly connected to the middle of the length of the short connecting rod 576. The electric telescopic rod 573 is electrically connected to the controller 2, which is used to control the extension and retraction of the electric telescopic rod 573 so that the clamping block 571 can lock or unlock the pull rope 511 via the pulley 53.

[0066] In a specific embodiment, Figure 1 As shown, a housing 7 is detachably connected to the top of the lifting plate 1. A third through-hole 71 is formed in the top of the housing 7, allowing the first lifting ring 11 to extend through the third through-hole 71, thereby facilitating the locking of the first lifting ring 11 by external lifting equipment. The provision of the housing 7 effectively prevents external dust, rainwater, etc. from entering the interior of the lifting plate 1 and affecting the service life of the internal components.

[0067] A solar panel 72 is also provided on the top surface of the housing 7, and the solar panel 72 is electrically connected to the mobile power supply 6. When working outdoors, the solar panel 72 can convert solar energy into electrical energy to continuously charge the mobile power supply 6, so that the mobile power supply 6 has sufficient power during use.

[0068] The following uses the prefabricated column 10 as an example of a prefabricated component to specifically describe the use of the lifting and positioning equipment for assembled prefabricated components provided in the embodiment of the present application.

[0069] First, the first screw 43 connected to the extended end of the lifting rope 421 is threadedly fixed to the prefabricated component's pre-reserved threaded hole. Next, the hook or wire rope of the external lifting equipment is locked into the pull ring. After checking and confirming that everything is correct, the prefabricated column 10 is erected. Third, the pull ring and the connection between the first screw 43 and the prefabricated column 10 are checked to ensure they are intact. Finally, the positioning block 52 is fixed to the side wall of the prefabricated column 10 with bolts. After installation, the lifting operation is carried out, using a slow start, fast rise, and slow lowering operation method.

[0070] During the slow lifting process, the on-site commander controls the start-up of the lifting and positioning equipment for the assembled prefabricated column 10 provided in the embodiment of the present application through a mobile terminal. The tension sensor 41 detects the tension value generated by the prefabricated column 10 during the lifting process, and converts the tension value into an electrical signal and transmits it to the controller 2. The controller 2 sends a signal to control the rotation of the electric motor based on the received electrical signal corresponding to the tension size. The electric motor drives the lead screw 33 to rotate, driving the slider 32 to move to a suitable position so that the tension values ​​​​of each tension sensor 41 are equal. This process automatically adjusts the center of gravity of the hoisted prefabricated column 10 to be directly below the lifting plate 1. This center of gravity adjustment process can not only ensure the safety and stability during the lifting process, but also reduce the time for the driver of the lifting equipment to make adjustments during operation, thereby improving the lifting efficiency.

[0071] When the prefabricated column 10 is hoisted to a position about 1.5m above the installation location, the external hoisting equipment can be directly suspended, and the staff can operate the mobile terminal to make the controller 2 control the first electric winch 42 to slowly adjust the lifting rope 421 to descend as a whole. When the prefabricated column 10 reaches the appropriate position above the installation location, the staff can operate the mobile terminal to make the controller 2 control the corresponding second electric winch 51 to tighten the pull rope 511, and the pull rope 511 tightens one or two sides of the corresponding prefabricated column 10, causing the prefabricated column 10 to tilt slightly, ensuring that the ground-reserved dowel bars at the installation location correspond to the grouting pipes reserved for the prefabricated column 10 one by one and can all be accurately inserted into the grouting pipes, and then use the controller 2 to control each first electric winch 42 to slowly adjust the lifting rope 421 to extend as a whole, so that the prefabricated column 10 slowly descends. The present application adopts the inclination adjustment mechanism 5 to adjust the inclination of the prefabricated column 10, which can not only reduce the time for workers to make repeated adjustments manually, but also avoid the safety hazards in the manual adjustment process and reduce the labor intensity of workers.

[0072] When the prefabricated column 10 is lowered to about 30 cm away from the installation position, the staff operates the mobile terminal to make the controller 2 control the second electric winch 51 to loosen the pull rope 511. At the same time, the staff operates the mobile terminal to make the controller 2 control the electric telescopic rod 573 to extend to release the lock of the positioning block 52 on the pull rope 511, and then guide the fixed block 561 at the end of the pull rope 511, and fix the fixed block 561 to the outside of the installation position through the second screw 562 and the nut 563.

[0073] The staff operates through the mobile terminal to make the controller 2 control each first electric winch 42 to slowly adjust the lifting rope 421 to descend as a whole. When the gap between the bottom of the prefabricated column 10 and the installation position is about 30 cm, a pad of 1mm to 10mm different thicknesses is used between the bottom of the prefabricated column 10 and the installation surface to maintain a gap of 20mm between the bottom of the prefabricated column 10 and the installation surface for pouring grouting material, ensuring that the grouting material has good fluidity while also ensuring that the prefabricated column 10 meets the design elevation after installation.

[0074] After the prefabricated column 10 falls to the ground, the controller 2 controls the second electric winch 51 to tighten the corresponding pull rope 511 according to the inclination degree of the positioning block 52 detected by the high-precision inclinometer 55 inside the positioning block 52, so as to ensure the verticality of the prefabricated column 10 to the installation surface after installation. The controller 2 controls the electric telescopic rod 573 to retract, so that the positioning block 52 locks the pull rope 511 again; the locking mechanism of the positioning block 52 on the pull rope 511 can avoid automatic locking of the pull rope 511 due to circuit failure or power outage, thereby avoiding safety accidents caused by the pull rope 511 being out of control.

[0075] After the pull rope 511 is locked, the locking device on the outside of the lifting ring can be removed to facilitate other operations of the tower crane or crane. The lifting plate 1 can be temporarily placed on the top of the prefabricated column 10. After the bottom of the prefabricated column 10 is grouting and solidified, the lifting and positioning equipment for assembled prefabricated components provided in the embodiment of this application can be removed.

[0076] During the operation process of using the hoisting and positioning equipment for assembled prefabricated columns 10 provided by the embodiments of the present application, the labor intensity of on-site construction workers can be reduced, the operation process of remotely controlling the hoisting equipment can be simplified, and the assembly efficiency of the prefabricated columns 10 can be improved. This makes the adjustment of the prefabricated columns 10 during the hoisting and installation process simpler and more accurate, the operation is safer and more convenient, and the operation efficiency is higher.
