Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire rope anti-loosening technology, specifically a crane wire rope anti-loosening support device. Background Technology
[0002] A wire rope is a helical bundle of steel wires that meet specific mechanical and geometric requirements, twisted together according to certain rules. It consists of steel wires, a core, and lubricant. The process involves first twisting multiple layers of steel wires into strands, then winding a certain number of strands around the core to form a helical shape.
[0003] Existing overhead crane wire ropes are prone to looseness during use. Loose wire ropes will "sway and swing" (commonly known as "rope swaying") when lifting heavy objects. Especially during crane movement, the amplitude of the swaying will increase with the running speed, making it impossible to accurately position the target location (such as equipment installation and material transfer in the workshop). Repeated adjustments are required, which seriously slows down the production rhythm. In addition, loose wire ropes may also entangle and knot each other.
[0004] Therefore, a solution is needed. Utility Model Content

[0012] (III) Beneficial Effects
[0013] This utility model provides a support device for preventing the loosening of a crane wire rope. It has the following beneficial effects:
[0014] This solution includes a crane wire rope anti-loosening support device. On one hand, relying on the wire rope tensioning device, a pressure motor drives the threaded rod, which in turn moves the rear drive plate and the first and second mounting arms. This causes the pressure wheel to apply a continuous tension force to the wire rope. At the same time, the outer limiting rings on the surfaces of the guide wheels in the lower and upper guide devices precisely restrict the position of the wire rope, preventing the wire rope from loosening at the source. This significantly reduces the "rope swaying" phenomenon when the crane is lifting heavy objects, making the heavy objects more stable during crane movement. It also facilitates precise positioning of target positions such as workshop equipment installation and material transfer without repeated adjustments, effectively accelerating the production pace. Furthermore, it prevents multiple wire ropes from tangling and knotting, ensuring the orderly operation of the wire rope and reducing downtime and manual maintenance time. On the other hand, the rear mounting frame adopts an integrated structure of base plate, support plate, and top plate, combined with triangular reinforcing blocks (to enhance the connection strength between the side stabilizing feet and the base plate), V-shaped structural blocks (to increase the support force of the reinforcing opening), and side stabilizing feet with locking holes (for easy and secure installation), significantly improving the overall structural strength and deformation resistance of the device. The sliding port and sliding groove of the main mounting base cooperate with the sliding block of the wire rope tensioning device to ensure smooth and stable tensioning, ensuring that the wire rope tension remains stable. This design allows the device to reliably withstand wire rope tension for a long time, reducing the frequency of failures and maintenance, continuously ensuring the anti-loosening function, comprehensively solving a series of problems caused by wire rope loosening in existing technologies, and greatly improving the efficiency, accuracy, and reliability of overhead crane lifting and material handling.

[0020] 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.
[0021] Please see Figure 1-4 This utility model provides a technical solution:
[0022] Example 1
[0023] To address the aforementioned problems: existing overhead crane wire ropes are prone to looseness during use, and loose wire ropes will "sway and swing" (commonly known as "rope swaying") when lifting heavy objects. Especially during crane movement, the amplitude of the swaying of the heavy object will increase with the increase of the running speed, making it impossible to accurately position the target location (such as equipment installation and material transfer in the workshop), requiring repeated adjustments, which seriously slows down the production rhythm. In addition, loose wire ropes may also entangle and knot each other.
[0024] The solution is as follows: A crane wire rope anti-loosening support device includes a device body 1. The device body 1 includes a main mounting base 2, a lower guide device 3, an upper guide device 4, a wire tensioning device 5, and a rear mounting frame 6. The rear mounting frame 6 is fixed to the rear end of the main mounting base 2. The lower guide device 3 and the upper guide device 4 are welded to the front end of the main mounting base 2. The lower guide device 3 is located above the upper guide device 4. The wire tensioning device 5 passes through the main mounting base 2 and is located between the lower guide device 3 and the upper guide device 4. The wire tensioning device 5 includes a first mounting arm 7, a second mounting arm 8, a rear drive plate 9, a pressure wheel 10, a pressure motor 11, and a threaded rod 12. The first mounting arm 7 and the second mounting arm... The components 8 are distributed in a horizontally equidistant manner. The rear drive plate 9 is installed at the rear end of the first mounting arm 7 and the second mounting arm 8. The front ends of the first mounting arm 7 and the second mounting arm 8 are arc-shaped. The pressure wheel 10 is installed between the first mounting arm 7 and the second mounting arm 8 through a rotating shaft. The surface of the rear drive plate 9 is provided with a threaded drive hole 13. The pressure motor 11 is fixed to the rear end of the rear mounting frame 6 by screws. The threaded rod 12 is installed at the drive end of the pressure motor 11. The pressure motor 11 is connected to the rear drive plate 9 through the threaded rod 12. The surface of the pressure wheel 10 is provided with a set of limiting outer rings 14. The outer sides of the first mounting arm 7 and the second mounting arm 8 are provided with sliding blocks 15, which are rectangular in shape.
[0025] Analysis of the above: The clamping motor 11 drives the threaded rod 12 to rotate, which, through the threaded drive hole 13 of the rear drive plate 9, drives the rear drive plate 9, the first mounting arm 7, the second mounting arm 8, and the clamping wheel 10 to move back and forth, thereby tightening the wire rope. When the wire rope is loose, the clamping motor 11 is started, controlling the threaded rod 12 to rotate forward, pushing the clamping wheel 10 towards the wire rope to apply tension. When fine adjustment of the tension is required, the position of the clamping wheel 10 is adjusted by rotating the motor forward and backward. Relying on the active drive of the clamping motor 11 and the transmission of the threaded rod 12, the wire rope can be continuously and adjustablely tightened. The limiting outer ring 14 on the surface of the clamping wheel 10 can accurately limit the wire rope and prevent deviation. The sliding block 15 on the outside of the first and second mounting arms cooperates with the sliding groove 17 of the main mounting seat, making the tightening action smooth and stable, reducing rope shaking and tangling problems from the root.
[0026] Example 2:
[0027] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the main mounting base 2 has a rectangular structure, and a sliding opening 16 is provided at the center of the surface of the main mounting base 2. The sliding opening 16 has a rectangular structure, and sliding grooves 17 are provided at both the left and right ends of the sliding opening 16.
[0028] Analysis of the above content: The main mounting base 2 provides the installation foundation for the wire tensioning device 5. The sliding port 16 allows the tensioning device components to pass through and slide back and forth. The sliding groove 17 cooperates with the sliding block 15 to limit the sliding direction and ensure the stability of the tensioning process. During installation, the sliding block 15 of the wire tensioning device 5 is embedded into the sliding groove 17, so that the wire tensioning device 5 can move smoothly along the sliding port 16. There is no additional operation in daily life. It plays a structural support and guiding role. The rectangular structure is stable and reliable. The design of the sliding port 16 and the sliding groove 17 allows the wire tensioning device to move accurately and smoothly, providing a reliable structural foundation for the stable tensioning of the wire rope.
[0029] Example 3:
[0030] Please see Figure 1-4This utility model provides a technical solution based on Embodiment 1: The rear mounting frame 6 includes a base plate 18, a support plate 19, and a top plate 20. The base plate 18, support plate 19, and top plate 20 are smoothly transitioned and integrally formed. The support plate 19 is located at the top rear end of the base plate 18, and the top plate 20 is located at the top of the support plate 19. An outlet 21 is provided at the center of the surface of the support plate 19. Side stabilizing feet 22 are provided on both the left and right sides of the base plate 18. The side stabilizing feet 22 have a rectangular structure. Several sets of reinforcing blocks 23 are provided between the side stabilizing feet 22 and the base plate 18. The reinforcing blocks 23 have a triangular structure and an arc-shaped top. Several sets of locking holes 24 are provided on the surface of the side stabilizing feet 22. Several sets of reinforcing openings 25 are provided on the surface of the base plate 18 and the top plate 20 in a horizontally equidistant manner. The reinforcing openings 25 have a rectangular structure. Structural blocks 26 are provided inside the reinforcing openings 25. The structural blocks 26 have a V-shaped structure.
[0031] Analysis of the above content: The rear mounting frame 6 serves as the mounting carrier for the clamping motor 11. The integrally formed base plate 18, support plate 19, and top plate 20 provide overall support. The through-hole 21 allows the threaded rod 12 to pass through and connect to the rear drive plate 9. The side stabilizing foot 22 is fixed to the outside through the locking hole 24. The reinforcing block 23 enhances the connection strength between the side stabilizing foot and the base plate. The V-shaped structural block 26 in the reinforcing opening 25 improves the structural rigidity of the base plate and the top plate. During installation, the locking hole 24 of the side stabilizing foot 22 is used to fix the rear mounting frame to the crane with fasteners. During normal operation, it continuously provides stable support. The base plate 18, support plate 19, and top plate 20 are integrally formed, resulting in good structural strength and integrity. The design of the triangular reinforcing block 23 (with an arc-shaped top) and the V-shaped structural block 26 enhances the structural resistance to deformation and can withstand transmission tension for a long time. The through-hole 21 ensures smooth transmission of the threaded rod, and the locking hole of the side stabilizing foot facilitates stable installation, improving the reliability of the connection between the device and the crane.
[0032] Example 4:
[0033] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the lower guide device 3 and the upper guide device 4 both include a guide frame 27 and a guide wheel 28. The guide frame 27 has a U-shaped structure. The guide wheel 28 is installed inside the front end of the guide frame 27 through a rotating shaft. A set of limiting outer rings 14 are also provided on the surface of the guide wheel 28.
[0034] Analysis of the above: The guide frame 27 provides mounting support for the guide wheel 28. The guide wheel 28 rotates through a shaft to guide the wire rope. The limiting outer ring 14 on its surface cooperates with the limiting outer ring of the clamping wheel to restrict the position of the wire rope. When the wire rope is wound, it is embedded into the guide wheel 28 along the recess of the guide frame 27. The rotation of the guide wheel reduces friction damage. In daily use, the guide wheel rotates with the movement of the wire rope, continuously guiding and limiting. The U-shaped guide frame 27 facilitates the embedding of the wire rope, and the rotation of the guide wheel 28 reduces the wear of the wire rope. The limiting outer ring 14 precisely restricts the direction of the wire rope. In cooperation with the wire rope tensioning device, it not only prevents deviation after loosening, but also avoids multiple wire ropes from getting tangled or knotted, ensuring the orderly operation of the wire rope and helping to improve the tensioning effect.
[0035] Working principle: During operation, the wire rope passes sequentially through the guide wheel 28 of the lower guide device 3, the pressure wheel 10 of the wire tensioning device 5, and the guide wheel 28 of the upper guide device 4. The guide wheel 28 and the limiting outer ring 14 on the surface of the pressure wheel 10 together restrict the lateral position of the wire rope to prevent deviation. When the wire rope becomes loose, the pressure motor 11 on the rear mounting frame 6 starts, driving the threaded rod 12 to rotate. Through the threaded drive hole 13 of the rear drive plate 9, the rear drive plate 9, the first mounting arm 7, the second mounting arm 8, and the pressure wheel 10 move smoothly along the sliding groove 17 of the main mounting seat 2, so that the pressure wheel 10 applies a continuous tension force to the wire rope to eliminate slack. If the tension needs to be adjusted, the forward and reverse rotation of the pressure motor 11 can control the forward and reverse position of the pressure wheel 10.
[0036] The present invention comprises: 1. Device body; 2. Main mounting base; 3. Lower guide device; 4. Upper guide device; 5. Steel wire tensioning device; 6. Rear mounting frame; 7. First mounting arm; 8. Second mounting arm; 9. Rear drive plate; 10. Pressure wheel; 11. Pressure motor; 12. Threaded rod; 13. Threaded drive hole; 14. Limiting outer ring; 15. Sliding block; 16. Sliding port; 17. Sliding groove; 18. Base plate; 19. Support plate; 20. Top plate; 21. Through-hole; 22. Side stabilizing foot; 23. Reinforcing block; 24. Locking hole; 25. Reinforcing port; 26. Structural block; 27. Guide frame; 28. Guide wheel. All components are general standard parts or parts known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or other means. Conventional experimental methods have revealed that the problem solved by this invention is that existing overhead crane wire ropes are prone to loosening during use. Loose wire ropes will "sway and swing" (commonly known as "rope swaying") when lifting heavy objects, especially during crane movement, the amplitude of the swaying will increase with the running speed, making it impossible to accurately position the target location (such as equipment installation and material transfer in a workshop), requiring repeated adjustments, which seriously slows down the production rhythm. In addition, loose wire ropes may also entangle and knot each other. This invention, through the combination of the above-mentioned components, can reliably withstand the tension of the wire rope for a long time, reduce the frequency of failures and maintenance, continuously ensure the anti-loosening function, comprehensively solve the series of problems caused by loose wire ropes in the prior art, and significantly improve the efficiency, accuracy and reliability of overhead crane lifting and material transfer.
