These corners can damage the wire ropes when they come into contact with them, significantly reducing their service life. This situation not only increases construction costs but can also lead to safety incidents caused by damaged wire ropes, creating significant inconvenience and potential risks for hoisting operations.

[0038] refer to Figure 1-Figure 2 The present application provides a lifting protection device for a steel wire rope 20 of a sharp-angle prefabricated component, comprising:

[0039] A protective member 10 is provided between the prefabricated component and the steel wire rope 20. The pressure generated by the steel wire rope 20 acts on the protective member 10 and acts on the prefabricated component through the protective member 10.

[0040] The protection member 10 includes a hinge shaft 101 and a protection block 102. The protection block 102 includes two pieces, each of which is rotatably connected to the hinge shaft 101.

[0041] The side wall of the protection block 102 is connected to a penetration piece 30 , and the steel wire rope 20 passes through the penetration piece 30 to form a constraint on the steel wire rope 20 .

[0042] During the hoisting process, the pressure generated by the steel wire rope 20 first acts on the protective member 10. The hinge shaft 101 in the protective member 10 is set at the sharp corner of the prefabricated component, and the two protective blocks 102 can rotate around the hinge shaft 101 to fit the sharp corner shape of the prefabricated component. When the steel wire rope 20 passes through the penetration piece 30 on the protective block 102, the penetration piece 30 constrains the steel wire rope 20. For example, when the penetration piece 30 is a triangular block 301, the steel wire rope 20 penetrates the penetration hole 302 of the triangular block 301 and bends before passing out. The triangular block 301 bears the pressure of the steel wire rope 20 and disperses it to the protective block 102. The protective block 102 then applies force evenly to the prefabricated component, avoiding damage to the prefabricated component caused by stress concentration at the sharp corner, and also preventing the sharp corner of the prefabricated component from wearing the steel wire rope 20.

[0043] When the threading member 30 comprises a slide rail 303, a slider, a crosspiece 304, or the like, the slider slides on the slide rail 303. After being adjusted to the desired position, the crosspiece 304 is inserted into the connection hole. A hole for accommodating the wire rope 20 is formed between the crosspiece 304 and the protective block 102, through which the wire rope 20 passes. Fasteners 305 (such as bolts and nuts) secure the slider, allowing the threading member 30 to stably restrain the wire rope 20. This structure allows for flexible adjustment based on the diameter and load conditions of the wire rope 20, ensuring a stable position of the wire rope 20 during the hoisting process and protecting the prefabricated component and the wire rope 20.

[0044] Before lifting, the rope connection assembly 40 comes into play. The extension piece 401 is rotatably connected to the protective member 10. A spring 402 connects the extension piece 401 to the clamp 403. The clamp 403 grips the wire rope 20, securing the protective member 10 in place between the wire rope 20 and the prefabricated component. During the lifting process, the protective member 10 and the threading member 30 work together to ensure the stability of the wire rope 20, enabling the entire lifting system to operate safely and efficiently, preventing any adverse effects on the prefabricated component and the lifting operation caused by movement of the protective member 10 or swaying of the wire rope 20.

[0045] The inflection point of the steel wire rope 20 is the outer wall of the hinge shaft 101, and the hinge shaft 101 is arranged at the sharp corner of the corresponding prefabricated component.

[0046] Positioning hinge 101 at the sharp corner of a prefabricated component and serving as the turning point for wire rope 20 allows the protection device to precisely address the forces acting at the corner. This leverages the hinge's position, allowing protection block 102 to rotate around it to adapt to the shape of the sharp corner. This effectively disperses the pressure from wire rope 20 on the sharp corner, preventing damage from concentrated force. It also ensures that wire rope 20 is positioned and angled appropriately, minimizing wear.

[0047] During hoisting, the steel wire rope 20 bends at the outer wall of the hinge shaft 101. Because the hinge shaft 101 is located at the sharp corner of the prefabricated component, when the steel wire rope 20 is subjected to force, the force is transmitted to the protection block 102 through the hinge shaft 101. The protection block 102 rotates around the hinge shaft 101 and can be adjusted according to the angle of the sharp corner of the prefabricated component, so that the protection block 102 fits tightly with the sharp corner of the prefabricated component, thereby evenly distributing the pressure of the steel wire rope 20 on the prefabricated component, avoiding excessive local pressure at the sharp corner, and maintaining the stability of the steel wire rope 20 during the hoisting process, reducing damage to the steel wire rope 20.

[0048] The penetration member 30 includes a triangular block 301 , and the vertical surface and the inclined surface of the triangular block 301 are provided with penetration holes 302 . The wire rope 20 penetrates from the penetration hole 302 of the first triangular block 301 and passes through the penetration hole 302 of the other triangular block 301 after bending.

[0049] The design of the triangular block 301 provides a stable threading path for the wire rope 20. The vertical and inclined holes 302 allow the wire rope 20 to change direction when passing through, effectively dispersing the force on the wire rope 20. This structure is simple and stable, and can constrain the movement of the wire rope 20 during the lifting process, reducing the concentrated pressure of the wire rope 20 on the protection block 102 and the prefabricated component. At the same time, it can also prevent the wire rope 20 itself from being damaged due to excessive bending or friction, thereby improving the stability and safety of the entire lifting system. When the lifting operation is carried out, the wire rope 20 passes through the threading hole 302 of one triangular block 301, then bends along the shape of the triangular block 301, and then passes out from the threading hole 302 of another triangular block 301. In this process, the triangular block 301 bears the tension and pressure of the wire rope 20, and transfers these forces evenly to the protection block 102. Due to the special shape of the triangular block 301 and the position of the through hole 302, the force direction and magnitude of the wire rope 20 are reasonably adjusted, ensuring the stability of the wire rope 20 during the lifting process, while protecting the prefabricated component and the wire rope 20.

[0050] The penetration member 30 includes a slide rail 303, two sliders, a cross piece 304, and a fastener 305. The slide rail 303 is set on the protection block 102. The slider is slidably connected to the slide rail 303. The sliding direction of the slider is perpendicular to the length direction of the protection block 102. The cross piece 304 is connected to one of the sliders. The other slider is provided with a connecting hole. The sliders can slide relative to each other, and after reaching a predetermined position, the cross piece 304 is inserted into the connecting hole. A hole for accommodating the wire rope 20 is formed between the cross piece 304 and the protection block 102, and the wire rope 20 passes through the hole. The fastener 305 is set on the slider and is used to lock the slider after reaching the position.

[0051] The structural design of this threading member 30 is highly flexible. The combination of the slide rail 303 and the slider allows the position of the slider to be adjusted according to the different specifications of the wire rope 20, thereby changing the size of the hole formed between the crosspiece 304 and the protective block 102 to accommodate wire ropes 20 of various diameters. Under different lifting conditions, it can be easily adjusted to the appropriate position to ensure effective restraint of the wire rope 20. The fastener 305 can ensure that the slider is fixed in the adjusted position, so that the entire threading member 30 remains stable during the lifting process, improving the device's compatibility with different wire ropes 20 and the safety of the lifting operation.

[0052] During the installation process, according to the diameter of the wire rope 20, the sliding block moves along the slide rail 303. After adjusting to the appropriate position, the cross piece 304 is inserted into the connecting hole of another block. At this time, a hole for the wire rope 20 to pass through is formed between the cross piece 304 and the protection block 102, and then the block is locked by the fastener 305. During hoisting, the wire rope 20 passes through the hole and is constrained by the cross piece 304 and the protection block 102. When the wire rope 20 is subjected to force, the force is transmitted to the slide rail 303 and the protection block 102 through the block. Since the block is fixed, the entire threading piece 30 can stably withstand the force of the wire rope 20, ensuring the stable position of the wire rope 20 during the hoisting process and protecting the prefabricated component and the wire rope 20.

[0053] The fastener 305 includes a bolt passing through the two sliders. A plurality of nuts are provided on the bolt for fixing the sliders respectively.

[0054] Bolts and multiple nuts are used as fasteners 305, which has a simple and reliable structure. The bolts passing through the two sliders can effectively connect them together, and the setting of multiple nuts can fix the two sliders separately, which can accurately adjust the position of the slider and maintain stability. This design is convenient for installation and adjustment, and can ensure that the slider will not loosen when subjected to forces of different directions and sizes, ensure that the threading piece 30 effectively constrains the wire rope 20, and improve the safety of the lifting process. After adjusting the position of the slider, the bolts are passed through the two sliders, and by tightening the nuts at different positions, the nuts are in close contact with the two sliders respectively, thereby applying pressure to the slider and fixing the slider to the predetermined position on the slide rail 303. During the lifting process, when the force generated by the wire rope 20 acts on the threading piece 30, the force exerted on the slider is transmitted and dispersed through the connection structure of the bolts and nuts. Due to the tightening effect of the nuts, the slider will not be displaced, ensuring the stability of the threading piece 30, thereby maintaining the stable state of the wire rope 20 and protecting the prefabricated component and the wire rope 20.

[0055] The crosspiece 304 includes multiple crosspieces. Providing multiple crosspieces 304 can further improve the restraining effect on the wire rope 20. Multiple crosspieces 304 can support and position the wire rope 20 at different positions as needed, so that the position of the wire rope 20 in the threading member 30 is more stable, and the force on the wire rope 20 can be better dispersed to prevent the wire rope 20 from shaking or shifting during the hoisting process, thereby reducing damage to the prefabricated components and the wire rope 20 itself, and improving the safety and stability of the hoisting. Multiple crosspieces 304 work in conjunction with the slider in the threading member 30 composed of the protective block 102 and the slider. When the slider is adjusted to the appropriate position, the multiple crosspieces 304 jointly restrict the wire rope 20 at different positions. During the lifting process, the force exerted on the wire rope 20 is transmitted to the slider and the protective block 102 through the crosspiece 304. The multiple crosspieces 304 share the pressure and tension of the wire rope 20, so that the wire rope 20 can be stably supported in all directions, ensuring that the position of the wire rope 20 in the threading member 30 is fixed, avoiding shaking or displacement due to uneven force, and protecting the prefabricated components and the wire rope 20.

[0056] The crossbar 304 is rotatable. The rotatable design of the crossbar 304 increases the flexibility of the threading member 30. When threading the wire rope 20, the crossbar 304 can be rotated to a suitable angle to facilitate the insertion of the wire rope 20. During the hoisting process, according to the force direction and magnitude changes of the wire rope 20, the crossbar 304 can be rotated and adjusted within a certain range to better adapt to the dynamic changes of the wire rope 20, ensure effective constraint on the wire rope 20, and reduce the wear of the wire rope 20, thereby improving the practicality of the device and its adaptability to complex hoisting conditions. During the installation phase, the crossbar 304 is rotated to an angle that does not hinder the insertion of the wire rope 20. After the wire rope 20 has passed through, the crossbar 304 is adjusted back to its normal working position. During the hoisting process, when the angle of the wire rope 20 changes due to the force, the crossbar 304 will rotate within a certain range according to the movement trend of the wire rope 20, so that the crossbar 304 can always maintain good contact and constraint with the wire rope 20. The force is transmitted to the slider and the protective block 102 via the rotatable crosspiece 304, maintaining the stability of the wire rope 20 in the threading member 30 while reducing wear caused by rigid friction between the wire rope 20 and the crosspiece 304. It should be noted that the length of the crosspiece 304 is shorter than the length of the slide rail 303, which facilitates the entry of the wire rope 20.

[0057] The slide rails 303 include multiple ones. Providing multiple slide rails 303 can enhance the structural strength and stability of the through-piece 30. Multiple slide rails 303 can share the force transmitted by the slider more evenly, making the slider more stable during the movement and fixation process. At the same time, this design can improve the through-piece 30's ability to withstand complex stress conditions, ensuring that the slider can operate stably on the slide rails 303 under the action of forces of different directions and magnitudes, thereby ensuring effective constraint on the wire rope 20 and improving the safety and reliability of the entire lifting device. During the operation of the through-piece 30, the slider slides and is fixed on multiple slide rails 303. When the wire rope 20 is subjected to stress and transmits the force to the slider, the slider disperses the force to the multiple slide rails 303. Multiple slide rails 303 jointly bear and transmit these forces, making the stress on the through-piece 30 more uniform, avoiding structural deformation or damage due to excessive local stress. During the hoisting process, this structure ensures the stability of the slider, thereby ensuring the stable constraint of the wire rope 20 by the penetration member 30, protecting the prefabricated component and the wire rope 20.

[0058] In some embodiments, the protective member 10 is further provided with a rope connection assembly 40, which is used to connect to the steel wire rope 20 when the protective member 10 is inserted between the steel wire rope 20 and the prefabricated component, thereby securing the protective member 10 prior to hoisting. The rope connection assembly 40 ensures that the protective member 10 is securely fixed in the correct position between the steel wire rope 20 and the prefabricated component prior to hoisting. This prevents the protective member 10 from accidentally moving during hoisting preparations and requiring readjustment, thereby improving the efficiency of hoisting preparations. Furthermore, it ensures that the protective member 10 is initially in the optimal working position, facilitating its function of protecting the prefabricated component and the steel wire rope 20 during the hoisting process and enhancing the stability and safety of the entire hoisting system. After the protective member 10 is placed between the steel wire rope 20 and the prefabricated component, the rope connection assembly 40 is used to connect it to the steel wire rope 20. Through the specific connection method of the rope connection assembly 40, such as clamping the steel wire rope 20 with a clip 403, the protective member 10 and the steel wire rope 20 form a relatively fixed whole. In the preparation stage before hoisting, the protective member 10 will not be displaced by external interference. When hoisting begins, the protective member 10 can immediately play its protective role, ensuring that the hoisting operation is in a stable and safe state from the beginning.

[0059] The device comprises an extension member 401, a spring 402, and a clip 403. The extension member 401 is rotatably connected to the protective member 10, the spring 402 is connected to the extension member 401, and the clip 403 is connected to the spring 402. The clip 403 is capable of clamping the wire rope 20. This structure consisting of the extension member 401, spring 402, and clip 403 is simple and practical. The rotatable connection between the extension member 401 and the protective member 10 allows the clip 403 to be flexibly adjusted within a certain range, facilitating the connection between the clip 403 and the wire rope 20. The clip 403 can be a conventional rope clip or a standard cross-shaped clip with a spring structure, such as a clip for clothes or documents.
