[0002] During the construction of prefabricated buildings, prefabricated components such as wall panels and floor slabs need to be lifted from transport vehicles and accurately installed in designated positions.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1-4 The present invention provides the following technical solution: a prefabricated building hoisting balancer, comprising a beam frame unit 1, multiple sets of adjustable hoisting units 3, a balance detection component for detecting the hoisting balance state, and a drive mechanism 6 for driving the position adjustment of the hoisting units 3. The balance detection component is signal-connected to the drive mechanism 6. The drive mechanism 6 drives the hoisting units 3 to move relative to the beam frame unit 1 according to the detection signal of the balance detection component, so as to dynamically adjust the hoisting center of gravity and realize the hoisting balance of the prefabricated components.

[0041] It should be noted that this utility model also includes a controller, which serves as the control core of the entire prefabricated building hoisting balancer and is used to control the operation of the balancer.

[0042] Optionally, by Figures 1-4As shown, in this embodiment, the beam frame unit 1 includes: a main balancing beam plate 11 and two symmetrically distributed auxiliary balancing beam plates 12. The main balancing beam plate 11 has a through first guide sliding hole 111, and at least two lifting lugs 2 are fixed on the top surface of the main balancing beam plate 11. The auxiliary balancing beam plates 12 pass through the first guide sliding hole 111, and two symmetrically distributed hoisting units 3 are provided on the auxiliary balancing beam plates 12. The driving mechanism 6 is used to drive the two auxiliary balancing beam plates 12 to move towards or in opposite directions; the hoisting unit 3 The system includes: an adjusting seat 31, a movable pulley 32, a fixed pulley 33, a wire rope 34, a hook 36, a first electric push rod 37, and a second electric push rod 5. A second guide hole 121 is provided within the auxiliary balance beam plate 12. The adjusting seat 31 is located within the second guide hole 121. The movable pulley 32 is movably mounted at the bottom of the adjusting seat 31. The fixed pulley 33 is fixed to the bottom surface of the adjusting seat 31. One end of the wire rope 34 is fixed to the movable pulley 32, and the other end passes over the fixed pulley 33. The hook 36 is located at the bottom of the wire rope 34. At the end, the first electric push rod 37 is fixed to the top surface of the adjusting seat 31, and the piston rod of the first electric push rod 37 passes through the adjusting seat 31 and is fixedly connected to the movable pulley 32. The second electric push rod 5 is fixed to the end of the auxiliary balance beam plate 12, and the piston rod of the second electric push rod 5 is fixedly connected to the adjusting seat 31. The balance detection component includes: tilt sensor 4 and tension sensor 35. The tilt sensor 4 is fixed to the top surface of the main balance beam plate 11, and the tension sensor 35 is fixed between the wire rope 34 and the hook 36. After adopting the above scheme, in use, firstly, according to the size of the prefabricated component (length and width of the main balance beam plate 11), by starting the drive mechanism 6 and the second electric push rod 5, the two auxiliary balance beam plates 12 move towards or in opposite directions along the first guide sliding hole 111 of the main balance beam plate 11 to adjust the distance between the two main balance beam plates 11. And by adjusting the distance between the two hoisting units 3 in the same group through the second electric push rod 5, the position of the four groups of hoisting units 3 is adapted to the size of the prefabricated component.

[0043] Then, the entire device is suspended on the lifting device by the lifting lugs 2 on the top surface of the main balance beam plate 11. The lifting points of the prefabricated components are then connected and fixed to the hooks 36 of the lifting unit 3, thus completing the preparatory work before lifting.

[0044] At this time, the balance detection component is activated simultaneously to monitor the hoisting status in real time: the tilt sensor 4 continuously detects the tilt angle of the main balance beam plate 11 to determine the horizontal balance status of the entire hoisting system; the tension sensor 35 accurately collects the tension value at each hook 36 to reflect the force distribution of each hoisting point on the precast component.

[0045] When the lifting equipment lifts the precast component, if the center of gravity of the precast component shifts, causing overall imbalance, the balance detection component will quickly capture the abnormal signal: if the main balance beam plate 11 tilts, the tilt angle sensor 4 will transmit the tilt angle signal to the controller; if the tension at each lifting point is uneven, the tension sensor 35 will synchronously feed back the tension difference signal to the controller.

[0046] After receiving the signal, the controller analyzes the cause of the imbalance using an algorithm and sends adjustment commands to the corresponding actuators.

[0047] Firstly, in response to imbalance, the controller controls the extension and retraction of the second electric push rod 5 at the end of the secondary balance beam plate 12. The piston rod of the second electric push rod 5 drives the adjusting seat 31 to move along the second guide sliding hole 121 of the secondary balance beam plate 12, changing the distance between the two lifting units 3 on the same secondary balance beam plate 12. If the tension in a certain area is too high, the adjusting seat 31 moves away from that area, thereby reducing the local tension by optimizing the distribution of lifting points.

[0048] Secondly, for the tension deviation of a single lifting point, the controller activates the first electric push rod 37 on the adjusting seat 31. The piston rod of the first electric push rod 37 drives the movable pulley 32 to move up and down, which, together with the fixed pulley 33, changes the effective suspension length of the wire rope 34: when the tension sensor 35 at a certain hook 36 detects that the tension is too large, the first electric push rod 37 shortens, pulls the movable pulley 32 upward, increases the sag of the wire rope 34, and reduces the tension at that lifting point; conversely, the first electric push rod 37 extends, pushes the movable pulley 32 downward, reduces the sag of the wire rope 34, increases the tension, and ensures that the tension at each lifting point is balanced.

[0049] By changing the initial height of the hook 36 through the first electric push rod 37, the hook 36 can also be adapted to irregular prefabricated components and to scenarios with different lifting point heights of the prefabricated components.

[0050] Throughout the hoisting process, the balance detection component continuously collects status signals. The controller dynamically adjusts the actions of the drive mechanism 6, the second electric push rod 5, and the first electric push rod 37 based on real-time data until the tilt sensor 4 detects that the main balance beam plate 11 is in a horizontal state and the values ​​of each tension sensor 35 tend to be consistent. At this point, the precast component achieves hoisting balance, ensuring the stability and safety of the hoisting process.

[0051] Optionally, by Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the drive mechanism 6 includes: a bidirectional threaded screw 61, a servo motor 62 fixed to one end of the main balance beam plate 11, and two guide rods 63 symmetrically fixed in the first guide sliding hole 111. The bidirectional threaded screw 61 is rotatably disposed in the first guide sliding hole 111, and the secondary balance beam plate 12 is threadedly engaged with the bidirectional threaded screw 61. The servo motor 62 drives the bidirectional threaded screw 61 to rotate, and the guide rods 63 pass through the secondary balance beam plate 12. With the above scheme, when adjusting the distance between the two secondary balance beam plates 12, the servo motor 62 is started, and its output shaft drives the bidirectional threaded screw 61 to rotate in the first guide sliding hole 111.

[0052] Since the two auxiliary balance beams 12 are threadedly engaged with the left and right reverse threads of the bidirectional threaded screw 61, and the auxiliary balance beams 12 are simultaneously limited by the guide rod 63 that passes through them, the rotation of the bidirectional threaded screw 61 is converted into the linear motion of the two auxiliary balance beams 12: if the bidirectional threaded screw 61 rotates clockwise, the two auxiliary balance beams 12 move closer to each other along the guide rod 63; if the bidirectional threaded screw 61 rotates counterclockwise, the two auxiliary balance beams 12 move away from each other in opposite directions.

[0053] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown in this embodiment, the outer wall of the secondary balance beam plate 12 is attached to the inner wall of the first guide sliding hole 111. After adopting the above solution, in use, firstly, the stability and accuracy of the secondary balance beam plate 12 during movement can be significantly improved. The attached state makes there almost no extra gap between the two, avoiding swaying or deviation when the secondary balance beam plate 12 moves in the first guide sliding hole 111. When the drive mechanism 6 drives the secondary balance beam plate 12 to move in opposite directions, this close fit ensures that it moves strictly according to the preset trajectory and will not produce additional displacement deviation due to gaps. This lays a stable foundation for the subsequent position adjustment of the hoisting unit 3 and helps to improve the accuracy of the overall hoisting balance adjustment.

[0054] Secondly, it can enhance the structural rigidity of the entire device. The secondary balance beam plate 12 and the first guide sliding hole 111 are closely fitted together, making the two form a more stable overall structure. When hoisting heavy objects, the load can be effectively distributed and transferred. The weight of the prefabricated components is transferred to the secondary balance beam plate 12 through the hoisting unit 3, and then transferred to the main balance beam plate 11 by the secondary balance beam plate 12. The close fit design makes the force transmission path more direct and smooth, reduces the stress concentration phenomenon caused by structural gaps, reduces the risk of damage to the device due to uneven force during hoisting, and extends the service life of the device.

[0055] Furthermore, it helps ensure the accuracy of balance detection. The stable movement of the secondary balance beam 12 without shaking allows the tilt sensor 4 in the balance detection assembly to more accurately detect the tilt angle of the main balance beam 11.

[0056] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, two symmetrically distributed guide sliders 311 are fixed on the outer wall of the adjusting seat 31. A third guide sliding hole 122 adapted to the guide sliders 311 is provided on the secondary balance beam plate 12. With the above scheme, the movement guidance accuracy of the adjusting seat 31 can be enhanced during use. When the second electric push rod 5 drives the adjusting seat 31 to move along the second guide sliding hole 121 of the secondary balance beam plate 12, the symmetrically distributed guide sliders 311 will be embedded in the third guide sliding hole 122 and slide synchronously to form a two-way limiting structure. This design can effectively limit the lateral displacement or torsion that may occur during the movement of the adjusting seat 31, and ensure that the adjusting seat 31 always slides smoothly along the preset trajectory. It avoids the relative position displacement of the moving pulley 32, the fixed pulley 33 and the wire rope 34 caused by the shaking of the adjusting seat 31, thereby ensuring the stability of the tension direction of the hoisting unit 3 on the prefabricated component and reducing the hoisting error caused by mechanical clearance.

[0057] Secondly, it can improve the load-bearing stability of the adjusting seat 31. When hoisting heavy objects, the adjusting seat 31 needs to bear the vertical load transmitted by the prefabricated components through the wire rope 34, and at the same time, it also needs to cope with the thrust or pull of the second electric push rod 5. The cooperation between the guide slider 311 and the third guide slide hole 122 can distribute part of the load to the side wall of the auxiliary balance beam plate 12, avoiding the adjusting seat 31 relying solely on the force on one side of the second guide slide hole 121, reducing the wear of the contact part between the adjusting seat 31 and the auxiliary balance beam plate 12, and extending the service life of the components.

[0058] In addition, the symmetrical distribution of the guide sliders 311 makes the force on the adjusting seat 31 more uniform, reducing component damage caused by local stress concentration.

[0059] It should be noted that the tension sensor 35, the first electric push rod 37, the tilt sensor 4, the second electric push rod 5, and the servo motor 62 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0060] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0061] Components not described in detail in this article are existing technologies.

[0062] The working principle and usage process of this utility model: When using the balancer of this utility model, firstly, based on the size of the prefabricated component (length and width of the main balance beam plate 11), the servo motor 62 of the drive mechanism 6 and the second electric push rod 5 are activated to make the two auxiliary balance beam plates 12 move towards or away from each other along the first guide sliding hole 111 of the main balance beam plate 11, thereby adjusting the distance between the two main balance beam plates 11. The distance between the two hoisting units 3 in the same group is adjusted by the second electric push rod 5, so that the position of the four groups of hoisting units 3 adapts to the size of the prefabricated component.

[0063] Then, the entire device is suspended on the lifting equipment by the lifting lugs 2 on the top surface of the main balance beam plate 11. The lifting points of the prefabricated components are then connected and fixed to the lifting hooks 36 of the lifting unit 3 to complete the preparatory work before lifting.

[0064] At this time, the balance detection component is activated simultaneously to monitor the hoisting status in real time: the tilt sensor 4 continuously detects the tilt angle of the main balance beam plate 11 to determine the horizontal balance status of the entire hoisting system; the tension sensor 35 accurately collects the tension value at each hook 36 to reflect the force distribution of each hoisting point on the precast component.

[0065] When the lifting equipment lifts the precast component, if the center of gravity of the precast component shifts and causes overall imbalance, the balance detection component will quickly capture the abnormal signal: if the main balance beam plate 11 tilts, the tilt angle sensor 4 will transmit the tilt angle signal to the controller; if the tension at each lifting point is uneven, the tension sensor 35 will synchronously feed back the tension difference signal to the controller.

[0066] After receiving the signal, the controller analyzes the cause of the imbalance using an algorithm and sends adjustment commands to the corresponding actuators.

[0067] Firstly, in response to imbalance, the controller controls the extension and retraction of the second electric push rod 5 at the end of the secondary balance beam plate 12. The piston rod of the second electric push rod 5 drives the adjustment seat 31 to move along the second guide sliding hole 121 of the secondary balance beam plate 12, changing the distance between the two lifting units 3 on the same secondary balance beam plate 12. If the tension in a certain area is too high, the adjustment seat 31 moves away from that area, thereby reducing the local tension by optimizing the distribution of lifting points.

[0068] Secondly, for the tension deviation of a single lifting point, the controller activates the first electric push rod 37 on the adjusting seat 31. The piston rod of the first electric push rod 37 drives the movable pulley 32 to move up and down, which, in conjunction with the fixed pulley 33, changes the effective suspension length of the wire rope 34: when the tension sensor 35 at a certain hook 36 detects that the tension is too large, the first electric push rod 37 shortens, pulls the movable pulley 32 upward, increases the sag of the wire rope 34, and reduces the tension at that lifting point; conversely, the first electric push rod 37 extends, pushes the movable pulley 32 downward, reduces the sag of the wire rope 34, increases the tension, and ensures that the tension at each lifting point is balanced.

[0069] By changing the initial height of the hook 36 through the first electric push rod 37, the hook 36 can also be adapted to irregular prefabricated components and to scenarios with different lifting point heights of the prefabricated components.

[0070] Throughout the hoisting process, the balance detection component continuously collects status signals. The controller dynamically adjusts the actions of the drive mechanism 6, the second electric push rod 5, and the first electric push rod 37 based on real-time data until the tilt sensor 4 detects that the main balance beam plate 11 is in a horizontal state and the values ​​of each tension sensor 35 tend to be consistent. At this point, the precast component achieves hoisting balance, ensuring the stability and safety of the hoisting process.

[0071] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
