Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of hoisting and positioning devices, and more specifically, to a hoisting and positioning device for prefabricated building components. Background Technology
[0002] In prefabricated building construction, irregular prefabricated components, due to their complex shapes and uneven center of gravity distribution, present greater challenges in hoisting and positioning compared to ordinary scaffolding and pipework. Traditional hoisting operations rely on rigid lifting equipment and fixed lifting points, which cannot adapt to the varied shapes of components. During hoisting, it is difficult to form a stable mechanical constraint between the component and the lifting equipment, causing the component to sway and rotate due to uneven force at the moment of lifting. This not only increases the difficulty of positioning but also poses safety hazards.
[0003] Existing hoisting and positioning devices mostly adopt a universal design, fixing components through simple binding or clamping methods, which makes it difficult to provide comprehensive constraints on irregular components. These devices cannot adjust the hoisting force points according to the component's shape and center of gravity. During the hoisting process, the component is prone to displacement due to gravity and inertia, resulting in poor hoisting performance of prefabricated components. Utility Model Content
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a hoisting and positioning device for prefabricated building components, which solves the technical problem that swaying and rotation easily occur when hoisting prefabricated components by hoisting devices in the prior art, resulting in poor hoisting effect.
[0005] According to one aspect, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, comprising:
[0006] A lifting rope, wherein the lifting rope has connecting loops at both ends;
[0007] A hook lifting component having a first through channel, through which the lifting rope passes, is looped around the lifting rope, and is located in the middle of the lifting rope;
[0008] A guide ball is rotatably mounted on the hook and its end extends into the first through-channel and abuts against the lifting rope, allowing the hook and lifting member to slide relative to the lifting rope.
[0009] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, wherein one side of the hook hoisting member has a strip-shaped mounting opening, the strip-shaped mounting opening being used to install the hoisting rope so that the hoisting rope is inserted into the first through-channel.

[0011] A sliding baffle is slidably disposed on the hook lifting component and located on one side of the strip-shaped installation opening. After sliding, it is used to seal the strip-shaped installation opening.
[0012] An elastic element, one end of which acts on the sliding baffle and the other end of which acts on the hook, provides a force for the sliding baffle to slide and seal the strip-shaped installation opening.
[0013] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, wherein the hook hoisting component includes:
[0014] An intermediate body, the bottom of which has several anti-slip protrusions;
[0015] The intermediate body has several swing bodies sequentially hinged to both ends.
[0016] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, wherein both the intermediate body and the swinging body include an inner sleeve and an outer sleeve, and a plurality of spherical receiving spaces are formed between the inner sleeve and the outer sleeve. The guide ball is disposed in the spherical receiving space, and the spherical receiving space is connected to the first through channel, such that the end of the guide ball extends into the first through channel.
[0017] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, which further includes:
[0018] A support member having a second through channel through which the hoisting rope passes. The support member and the connecting ring are respectively located on both sides of the precast component to support the hoisting rope away from the precast component.
[0019] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, wherein the supporting member is triangular and the second through channel is located on one side of one side of the supporting member.
[0020] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, wherein the second through-channel is arc-shaped.
[0021] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, wherein the supporting member has an abutting edge for abutting with the prefabricated component, and the thickness of the abutting edge is greater than the thickness of the other two sides of the supporting member.
[0022] For example, at least one embodiment of this disclosure provides a hoisting and positioning device for prefabricated building components, wherein the supporting member has a connecting hole and further includes a U-shaped clip, the U-shaped clip connecting the connecting ring and the connecting hole.
[0023] The beneficial effects of the embodiments disclosed herein are as follows:
[0024] This disclosure utilizes lifting ropes, hooks, and guide balls to optimize the lifting force points and mechanical constraints. The lifting ropes are connected to the precast components via connecting rings, providing a basic connection for lifting. The hooks are fitted around the middle of the lifting ropes, and the guide balls allow the hooks to slide relative to the ropes.

[0039] like Figures 1-6 As shown, this invention discloses a hoisting and positioning device for prefabricated building components according to one embodiment. It utilizes the synergistic effect of a hoisting rope 100, a hook 200, and a guide ball 300 to optimize the hoisting force point and mechanical constraints. The hoisting rope 100 is connected to the prefabricated component via a connecting ring 101, providing a basic connection for hoisting. The hook 200 is fitted around the middle of the hoisting rope 100, and the guide ball 300 allows the hook 200 to slide relative to the hoisting rope 100. This design allows for real-time adjustment of the hook 200's position based on the component's center of gravity and shape, resulting in better balance of hoisting force. This solves the problems of uneven force distribution, swaying, and rotation during the hoisting of irregular prefabricated components, improving the accuracy and safety of hoisting positioning.
[0040] The lifting rope 100 is made of high-strength, flexible steel wire rope. For precast components with large weight, steel wire rope with a larger diameter can be selected to ensure the safety of the lifting process.
[0041] The connecting ring 101 can be formed by bending the end of the lifting rope 100, which facilitates the passage of connectors such as U-shaped clips, ensuring sufficient strength and stability when connecting prefabricated components and lifting equipment.
[0042] The hook lifting component 200 is block-shaped, and its length is determined according to the actual lifting requirements and its coordination with the lifting rope. The first through channel 201 is a circular through hole located at the center of the hook lifting component 200, with a diameter larger than that of the lifting rope 100, ensuring that the lifting rope 100 can pass through smoothly and has sufficient room to move within the channel. A lifting hook connecting part is provided at the top of the hook lifting component 200. This connecting part is a boss structure with a hole, the diameter of which is determined according to the size of the lifting hook, and it is connected to the lifting hook by bolts or pins.
[0043] The guide ball 300 rolls relative to the lifting rope 100 to achieve relative sliding of the lifting rope 100. An installation hole adapted to the guide ball 300 is machined on the hook lifting member 200. The installation hole is a countersunk hole structure. After the guide ball 300 is installed, its end can extend into the first through channel 201 and abut against the lifting rope 100. At the same time, the rotation flexibility of the guide ball 300 will not be affected by the installation being too deep.
[0044] Installation and Lubrication: Install the guide ball 300 into the mounting hole of the hook 200. To ensure smooth rotation of the guide ball 300, apply an appropriate amount of lubricating grease, such as lithium-based grease, to the mounting hole and the surface of the guide ball 300. The grease has good lubrication and anti-wear properties, effectively reducing friction between the guide ball 300 and the mounting hole, extending the service life of the guide ball 300, and ensuring the stability of the hook 200 sliding on the lifting rope 100.
[0045] Before hoisting, the hoisting rope 100 is passed through the first through-channel 201 of the hook 200, so that the hook 200 is located in the middle of the hoisting rope 100. The guide ball 300 is installed in the mounting hole of the hook 200. The end of the guide ball 300 is in the first through-channel 201 and abuts against the hoisting rope 100, so that the hook 200 can slide along the hoisting rope 100 to a certain extent. The hook 200 is used to be hoisted by the hook.
[0046] Based on the shape and center of gravity of the precast component, determine the binding points of the lifting rope 100 on the precast component. Use the connecting ring 101 to reliably connect the lifting rope 100 to the precast component. During the connection process, ensure that the connection between the connecting ring 101 and the precast component is firm, and that the tightening torque of the U-shaped clips and other connectors meets the requirements. For precast components with complex shapes, it may be necessary to adjust the binding point positions multiple times to ensure that the component is subjected to uniform force during lifting.
[0047] During the lifting phase, the lifting equipment is started, and the lifting hook is slowly raised. The hook pulls the hook lifting component 200 and the lifting rope 100. At this time, the lifting rope 100 gradually bears the force, and the precast component begins to be lifted. In the early stage of lifting, the condition of the precast component is closely observed, and the connection between the lifting rope 100 and the precast component is checked to ensure it is secure, and the position of the hook lifting component 200 on the lifting rope 100 is stable. Due to the function of the guide ball 300, the hook lifting component 200 will automatically slide and adjust its position on the lifting rope 100 according to the center of gravity of the precast component and the force at the moment of lifting, so as to better balance the lifting force.
[0048] During the hoisting process, the hook lifting component 200 can slide self-adjustingly on the hoisting rope 100 to readjust the hoisting force point. For example, when the precast component tilts to one side, the hook lifting component 200 will slide in the opposite direction of the tilt, increasing the hoisting force on that side and restoring the precast component to balance.
[0049] The guide ball 300 allows the hook lifting component 200 to slide flexibly on the lifting rope 100, automatically adjusting the lifting force point and effectively balancing the lifting force. This reduces the swaying and rotation amplitude of the precast components at the moment of lifting, improving the stability of the lifting process and reducing safety hazards caused by swaying and rotation.
[0050] This device can adjust the lifting force point in real time according to the different shapes and center of gravity distributions of prefabricated components, adapting to the lifting needs of various irregular prefabricated components. Compared with general-purpose lifting and positioning devices, it has a wider range of applications for irregular prefabricated components, improving the versatility and flexibility of the lifting and positioning device.
[0051] In some examples, such as Figure 6 As shown, a strip-shaped mounting port 202 is provided on one side of the hook lifting component 200, thereby optimizing the operation process of inserting the lifting rope 100 into the first through-channel 201. The strip-shaped mounting port 202 provides an entry path for the lifting rope 100, enabling the lifting rope 100 to be inserted into the first through-channel 201 more easily and quickly, improving the assembly efficiency of the device, thereby increasing the preparation speed of the entire lifting operation and ensuring that the lifting work can be carried out more efficiently.
[0052] A strip-shaped installation opening 202 is provided on one side of the hook lifting member 200 to facilitate the installation of the lifting rope 100 into the first through channel 201 from the side. The center line of the installation opening is in the same plane as the center line of the first through channel 201 to ensure that the lifting rope 100 can smoothly transition during the installation process and reduce jamming.
[0053] The addition of the strip-shaped mounting opening 202 shortens the installation time of the lifting rope 100. Despite the increase in the strip-shaped mounting opening 202, the overall structural strength of the hook lifting component 200 is not significantly affected through reasonable structural design and dimensional control. During actual lifting operations, the device remains stable, effectively ensuring the stability and positioning accuracy of the precast component lifting and maintaining the good performance of the original lifting and positioning device.
[0054] In some examples, such as Figure 6 As shown, the function and safety of the hoisting positioning device are improved by setting a sliding baffle 400 and an elastic element 500. Although the strip-shaped installation port 202 facilitates the insertion of the hoisting rope 100 into the first through-channel 201, during the hoisting process, the hoisting rope 100 may be at risk of coming off the strip-shaped installation port 202 due to factors such as swaying and vibration, which would seriously endanger the safety of the hoisting operation. After the hoisting rope 100 is inserted, the sliding baffle 400 can slide to seal the strip-shaped installation port 202 to prevent the hoisting rope 100 from coming off. The elastic element 500 provides a continuous sealing force to the sliding baffle 400, ensuring that even if the device is subjected to external impact or vibration during the entire hoisting process, the sliding baffle 400 can always maintain a closed state on the strip-shaped installation port 202, thereby improving the reliability and safety of the hoisting positioning device.
[0055] The sliding baffle 400 is designed as a rectangular plate structure. On both sides of the sliding baffle 400 that contact the hook lifting component 200, there are protruding guide strips. The cross-sectional shape of the guide strips is rectangular or trapezoidal. The length of the guide strips is the same as the length of the sliding baffle 400. The hook lifting component 200 has a guide groove that matches the guide strip at the corresponding position. The depth of the guide groove is slightly greater than the height of the guide strip to ensure that the sliding baffle 400 can slide smoothly in the guide groove without lateral swaying.
[0056] The elastic element 500 is a compression spring. A blind hole that matches the outer diameter of the spring is machined on the hook and lifting part 200 near the strip mounting opening 202. A protrusion is set at the corresponding position on the sliding baffle 400. The height of the protrusion matches the part of the spring that is higher than the blind hole in the free state, ensuring that one end of the spring can be fitted on the protrusion and the other end is placed in the blind hole. Thus, the elastic element 500 acts on the sliding baffle 400 at one end and on the hook and lifting part 200 at the other end.
[0057] The cooperation between the sliding baffle 400 and the elastic element 500 eliminates the risk of the hoisting rope 100 detaching from the strip mounting opening 202. Compared with hoisting positioning devices without this structure, the risk of safety accidents caused by the hoisting rope detaching is greatly reduced, improving the safety of hoisting operations and ensuring the safety of personnel and equipment at the construction site.
[0058] The elastic element 500 continuously provides a sealing force to the sliding baffle 400, ensuring that the sliding baffle 400 reliably seals the strip mounting opening 202 under various complex working conditions. Over long-term use, the reliability of the device is significantly improved, reducing the failure rate caused by loose or displaced components.
[0059] Although the sliding baffle 400 and elastic element 500 have been added, the sliding operation of the sliding baffle 400 remains simple and does not significantly hinder the installation and disassembly of the lifting rope 100. While ensuring safety and reliability, the ease of operation of the original device is maintained, and operators can master the relevant operations without complicated training.
[0060] In some examples, such as Figure 1 , Figure 4 As shown, the hook lifting component 200 is divided into an intermediate body 210 and a swing body 220. Anti-slip protrusions 211 are provided at the bottom of the intermediate body 210 to improve the stability of the lifting process and its adaptability to prefabricated components. The anti-slip protrusions 211 at the bottom of the intermediate body 210 increase the friction with the surface of the prefabricated component, preventing the hook lifting component 200 from sliding on the hook. The swing body 220, hinged at both ends, can adaptively adjust according to the shape and contour of the prefabricated component, better conforming to the lifting rope 100 and distributing the lifting force, thereby improving the stability and safety of the lifting process and ensuring that the prefabricated component maintains a stable posture during lifting.
[0061] The intermediate body 210 is elongated, with anti-slip protrusions 211 evenly distributed on its bottom. These protrusions can be hemispherical, conical, or frustum-shaped. The anti-slip protrusions 211 are integrally formed with the intermediate body 210 through casting or machining to ensure strong connection. The distance between adjacent anti-slip protrusions 211 is determined based on actual conditions, ensuring sufficient friction without causing processing difficulties or affecting the structural strength of the intermediate body 210 due to excessively small spacing.
[0062] Several hinge holes are machined at both ends of the intermediate body 210. A hinge shaft that matches the hinge holes of the intermediate body 210 is machined at one end of the swing body 220. The diameter of the hinge shaft matches the diameter of the hinge holes of the intermediate body 210, ensuring that the connection is firm and the swing is flexible after hinge with the intermediate body 210.
[0063] Through the adaptive adjustment of the swing body 220 and the anti-slip effect of the anti-slip protrusion 211 at the bottom of the intermediate body 210, the swaying amplitude of the precast component during hoisting is reduced. The stable hoisting process makes it easier to accurately align the precast component with the installation position during positioning.
[0064] In some examples, both the intermediate body 210 and the swing body 220 include an inner sleeve 230 and an outer sleeve 240, with a plurality of spherical receiving spaces 231 formed between the inner sleeve 230 and the outer sleeve 240. A guide ball 300 is disposed in the spherical receiving space 231, and the spherical receiving space 231 is connected to the first through channel 201, so that the end of the guide ball 300 extends into the first through channel 201.
[0065] In some examples, such as Figure 4 As shown, the intermediate body 210 and the swing body 220 are designed to consist of an inner sleeve 230 and an outer sleeve 240, forming a spherical receiving space 231 between them to hold the guide ball 300. The spherical receiving space 231 is connected to the first through channel 201, thereby optimizing the performance of the hoisting and positioning device. By integrating the guide ball 300 into the structure of the intermediate body 210 and the swing body 220, this design makes the installation of the guide ball 300 more stable and better able to withstand various forces during hoisting. On the other hand, multiple guide balls 300 are evenly distributed around the hoisting rope 100, providing support and guidance to the hoisting rope 100 from multiple directions. This makes the sliding of the hook 200 relative to the hoisting rope 100 more stable and flexible, further improving the accuracy and stability of the attitude adjustment of the prefabricated components during hoisting.
[0066] Both the inner sleeve 230 and the outer sleeve 240 of the intermediate body 210 and the oscillating body 220 are made of high-strength and wear-resistant metal materials. The shape of the inner sleeve 230 is adapted to the internal contour of the intermediate body 210 or the oscillating body 220, and it is a structure with spherical grooves inside, which together form part of the spherical receiving space 231. The outer sleeve 240 covers the outside of the inner sleeve 230, and its interior also has spherical protrusions corresponding to the spherical grooves of the inner sleeve 230. The two together form a complete spherical receiving space 231.
[0067] The spherical receiving space 231 is evenly distributed between the inner sleeve 230 and the outer sleeve 240, ensuring that the guide ball 300 can roll freely in the spherical receiving space 231 without excessive shaking. The spherical receiving space 231 is connected to the first through channel 201 through connecting holes opened in the intermediate body 210 and the swing body 220. The diameter of the connecting hole is slightly smaller than the diameter of the guide ball 300, so that the end of the guide ball 300 can extend into the first through channel 201, but the guide ball 300 will not come out of the spherical receiving space 231.
[0068] Multiple guide balls 300 are evenly distributed around the lifting rope 100, providing support and guidance from multiple directions, which makes the sliding of the hook lifting component 200 relative to the lifting rope 100 smooth, reduces jamming and offset during the sliding process, and further improves the accuracy of adjusting the posture of the precast components during the lifting process.
[0069] In some examples, such as Figure 3 , Figure 5 As shown, a support member 600 is designed to optimize the spatial layout between the lifting rope 100 and the precast component, thereby improving the stability and safety of the lifting operation. When lifting irregular precast components, due to their complex shapes, if the lifting rope 100 is close to the surface of the precast component, it may wear down due to unevenness or sharp edges of the component surface, and may also affect the balance and attitude control of the precast component. The support member 600 passes through the lifting rope 100 through the second through channel 601 and is positioned on both sides of the precast component along with the connecting ring 101, thus keeping the lifting rope 100 away from the precast component. This avoids the wear problems that may occur from direct contact between the lifting rope and the precast component, and at the same time makes the force on the lifting rope more even, which helps to maintain the balance and stable attitude of the precast component during the lifting process.
[0070] The support component 600 is designed as a block structure for ease of installation and operation. To ensure sufficient strength, a high-strength metal material, such as cast steel or high-strength aluminum alloy, is selected. The second through channel 601 is circular and located on one side of the support component 600.
[0071] During the preparation phase of the hoisting operation, the hoisting rope 100 is passed through the second through-channel 601 of the support member 600, positioning the support member 600 at a suitable position on the hoisting rope 100. Then, the hoisting rope 100 is looped around the precast component, and the connecting ring 101 is connected to the hoisting rope 100, ensuring a secure connection. During installation, the position of the support member 600 on the hoisting rope 100 is adjusted so that it and the connecting ring 101 are symmetrically arranged relative to both sides of the precast component, thereby evenly lifting the hoisting rope 100 away from the precast component.
[0072] Depending on the shape and center of gravity distribution of the precast component, the position of the support member 600 may need to be fine-tuned. For example, for a precast component with its center of gravity shifted to one side, the support member 600 can be moved appropriately in the opposite direction of the center of gravity shift to better balance the force on the lifting rope 100 and ensure the stability of the precast component during the lifting process. Simultaneously, during the lifting process, operators can adjust the position of the support member 600 in real time by observing the posture of the precast component and the force on the lifting rope, based on the actual situation.
[0073] During the hoisting phase, the hoisting equipment is started, and the hoisting hook is slowly raised. In the initial stage of hoisting, because the supporting member 600 supports the hoisting rope 100 away from the precast component, the hoisting rope 100 will not be worn due to the unevenness or sharp edges of the precast component's surface. At the same time, the force on the hoisting rope 100 is more even, and the precast component can be hoisted relatively smoothly. As the hoisting height increases, the posture of the precast component, the tension of the hoisting rope, and the stability of the position of the supporting member 600 are continuously observed.
[0074] The support member 600 lifts the hoisting rope 100 away from the precast component, effectively avoiding direct friction and collision between the hoisting rope and the surface of the precast component. Compared with the case where the support member is not used, the wear of the hoisting rope is significantly reduced, the service life is extended, the replacement frequency of the hoisting rope is reduced, and the hoisting cost is reduced.
[0075] By evenly distributing the lifting ropes 100mm away from the precast components, the force on the lifting ropes is more uniform, reducing the swaying amplitude of the precast components during the lifting process compared to traditional methods. This improves the stability of the lifting, reduces safety hazards caused by swaying, and ensures the smooth progress of the lifting operation.
[0076] In some examples, such as Figure 1 , Figure 5As shown, the support member 600 is designed as a triangle, with the second through channel 601 located on one side, thereby further optimizing the performance of the lifting and positioning device. The triangular structure possesses excellent stability and mechanical properties, enabling it to more effectively withstand the forces from the lifting rope 100 and the prefabricated component during lifting, ensuring the stability of the support member 600 itself. The side-mounted layout of the second through channel 601 helps adjust the position of the lifting rope 100 relative to the prefabricated component, achieving more precise force transmission and distribution, thus better maintaining the balance and stability of the prefabricated component during lifting, improving lifting safety and positioning accuracy.
[0077] The triangular support structure 600 enhances stability during hoisting compared to ordinary shapes, better withstands hoisting forces, reduces the risk of hoisting risks due to deformation or displacement of the support structure, and ensures safe hoisting operations. The side-mounted second through-passage 601 allows for more precise adjustment of the hoisting rope 100 relative to the prefabricated component, resulting in more rational force transmission and distribution. This reduces the swaying amplitude of the prefabricated component during hoisting compared to traditional layouts, improving hoisting stability. The stable hoisting process and precise force control improve the positioning accuracy of the prefabricated component compared to traditional methods, further enhancing the construction quality of prefabricated buildings.
[0078] In some examples, the second through-channel 601 is designed as an arc to optimize the movement characteristics of the lifting rope 100 within the support member 600, thereby improving the stability and flexibility of the lifting process. The arc-shaped channel better accommodates the minute angle changes in the lifting rope 100 caused by factors such as the movement of prefabricated components and wind during lifting. Compared to a straight channel, it reduces localized stress concentration between the lifting rope 100 and the inner wall of the channel, thus reducing wear. Simultaneously, the arc-shaped channel provides a smoother guide for the lifting rope 100, helping to maintain the balance of the prefabricated components and making the force transmission more uniform during lifting, thereby improving the accuracy and safety of lifting positioning.
[0079] The arc-shaped second through channel 601 can effectively reduce the local stress concentration between the hoisting rope 100 and the inner wall of the channel. Compared with the straight channel, the wear of the hoisting rope 100 is reduced, the service life of the hoisting rope 100 is extended, and the cost and time of replacing the hoisting rope are reduced.
[0080] Improved hoisting stability: The curved channel provides a smoother guide for the hoisting rope 100, making the force transmission more uniform during hoisting. The swaying amplitude of the prefabricated components during hoisting is reduced compared to the straight channel, which greatly improves the stability of hoisting and reduces safety risks.
[0081] By precisely adjusting the position of the hoisting rope 100 through the arc-shaped channel, combined with a stable hoisting process, the positioning accuracy of prefabricated components is improved compared to the traditional straight channel, reducing installation errors and improving the construction quality of prefabricated buildings.
[0082] In some examples, such as Figure 1 , Figure 5 As shown, the support member 600 is provided with an abutment edge 602, and its thickness is greater than that of the other two sides. This optimizes the contact state between the support member 600 and the precast component during hoisting, improving the overall stability and safety of the hoisting. During hoisting, the support member 600 needs to withstand the pressure from the precast component and the tension of the hoisting rope 100. The abutment edge 602 directly abuts against the precast component. By increasing its thickness, the strength and rigidity of the abutment edge 602 can be improved, allowing it to better withstand the pressure from the precast component and preventing deformation of the support member 600 due to excessive pressure. This ensures that the hoisting rope 100 always maintains a suitable distance from the precast component, maintaining the stability of the hoisting. In addition, the thicker abutment edge 602 can also increase the contact area with the precast component, disperse the pressure, and reduce damage to the surface of the precast component.
[0083] The contact edge 602 must ensure sufficient contact length with the precast component to achieve uniform pressure distribution, and must have the same overall width as the support 600 to ensure the integrity and stability of the structure.
[0084] The increased thickness of the abutment edge 602 significantly improves the strength and rigidity of the contact area between the support member 600 and the precast component, thereby enhancing the structural stability of the support member 600 during hoisting compared to the case with uniform thickness. This effectively reduces the hoisting risks caused by deformation of the support member and ensures the safe conduct of hoisting operations.
[0085] The thicker abutment edge 602 increases the contact area with the precast component, disperses the pressure, and reduces the possibility of the support member 600 sliding on the surface of the precast component. The swaying amplitude of the precast component during hoisting is reduced compared to when the abutment edge thickness is uniform, improving the stability of hoisting and helping to control the posture of the precast component more accurately.
[0086] In some examples, such as Figure 1 , Figure 5As shown, a connecting hole 603 is provided on the support member 600, and the connecting ring 101 is connected to the connecting hole 603 through a U-shaped clamp 700, thereby strengthening the connection stability and coordination between the various components of the hoisting and positioning device. During the hoisting process, the weight of the prefabricated component and various external forces may cause the connection parts to loosen, affecting hoisting safety and positioning accuracy. The use of the U-shaped clamp 700, on the one hand, tightly connects the support member 600 and the connecting ring 101, ensuring that the support member 600 can continuously and stably support the hoisting rope 100 away from the prefabricated component; on the other hand, this rigid connection can make the hoisting force more evenly distributed among the components, improve the stability of the entire hoisting system, reduce safety hazards caused by loose connections, and thus more accurately control the attitude and position of the prefabricated component during the hoisting process.
