Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of bridge construction, and relates to an automatic cable strand combing device for main cable strands. BACKGROUND

[0002] As a key load-bearing component of a suspension bridge, the arrangement regularity of the strands of the main cable plays a crucial role in the overall structural performance and service life of the suspension bridge. During the erection of the main cable of the suspension bridge, the strands composed of numerous high-strength steel wires need to be accurately arranged and combined to ensure that the mechanical properties of the main cable are uniform and stable and meet the design requirements.

[0003] During production and actual use, if the numerous strands are not effectively arranged, the strands are prone to twisting and crossing. These problems can cause uneven stress distribution of the main cable, local stress concentration, and seriously affect the structural safety and durability of the suspension bridge. For example, the twisting of the strands can increase the friction between the steel wires, accelerate the wear and fatigue damage of the steel wires; and the crossing can damage the originally designed mechanical transmission path of the strands, reduce the load-carrying capacity and overall stiffness of the main cable.

[0004] According to the search of relevant information, the main solution to the above-mentioned problems of strand twisting and crossing is to use a combing plate to separate the strands by groups. During the erection of the main cable, the combing plate is installed at a predetermined position to limit the displacement of the strands and maintain their relative positional relationship. For example, in some early suspension bridge construction, a simple combing plate device was used in the construction of the main cable. The combing plate is a flat plate structure, which is inserted into the card slot on the main cable to separate the strands. However, this method is prone to installation position deviation of the combing plate during actual operation, which affects the arrangement effect of the strands. Moreover, during the sorting of the strands, the combing plate is mainly knocked into the strands by manual knocking, which can achieve the positioning of the strands to a certain extent, but has many disadvantages. Manual knocking cannot accurately control the knocking force and direction, which can easily damage the protective coating on the surface of the strands and reduce the corrosion resistance of the strands. At the same time, manual operation is low in efficiency and high in labor intensity, and as the construction error accumulates, the overall deviation of the strand arrangement increases, which affects the quality of the main cable.

[0005] In summary, the existing method of separating the strands by using a combing plate and manually knocking the strands into the main cable can solve the problems of strand twisting and crossing to a certain extent, but has the disadvantages of difficult to control the precision, easy to damage the strands, low efficiency, and high labor intensity. Therefore, it is necessary to develop an automatic cable strand combing device for the main cable to overcome the shortcomings of the prior art and achieve efficient, accurate and non-destructive cable strand combing operation. SUMMARY

[0006] The application provides an automatic main cable strand combing device, solves the operation efficiency of strand combing, reduces labor intensity, changes the current situation of low efficiency and high labor intensity of manual knocking, realizes automation and high efficiency of the main cable strand combing process, and meets the needs of large-scale suspension bridge construction and reduces construction cost.

[0007] In order to solve the above problems, the technical scheme adopted by the application is:

[0008] The automatic main cable strand combing device comprises a base, a fixing seat is arranged on the base, a plurality of hydraulic cylinders are arranged on the fixing seat, a combing plate is arranged on the hydraulic cylinders, the combing plate is not directly connected with the hydraulic cylinders, the combing plate is pushed into the strands by the extension of the hydraulic cylinders to separate and position the strands, a fixed frame is arranged on one side of the combing plate, and the strands are arranged on the fixed frame.

[0009] The principle of the scheme is that the fixing seat provides a stable support basis for the whole device, and the combing plate is not directly connected with the hydraulic cylinders, so that the device will not produce additional stress concentration and vibration transmission due to the rigid connection of the combing plate and the hydraulic cylinders during the combing operation, the risk of structural damage caused by uneven local stress or excessive vibration transmission is effectively avoided, the sliding device on the fixing seat enables the hydraulic cylinders to adjust the distance to adapt to strands with different distances and arrangements, and when the strands are combed and positioned, the hydraulic cylinders are started and elongated, the combing plate is pushed upward by the hydraulic cylinders, the combing plate is inserted between the strands under the action of the hydraulic cylinders, the strands are separated, and orderly arrangement is realized.

[0010] The fixed frame on one side of the combing plate plays an auxiliary positioning role, the strands are limited by the fixed frame, so that the twisting and crossing of the strands are effectively prevented, and the neat arrangement of the strands is ensured.

[0011] The beneficial effects of the scheme are:

[0012] From the perspective of improving construction efficiency, the design realizes automatic operation of strand combing. The traditional manual combing method is not only time-consuming and labor-intensive, but also low in efficiency, and the device in the device pushes the combing plate through a plurality of hydraulic cylinders, separates and positions the strands, and greatly shortens the time required for strand combing.

[0013] It has significant advantages in ensuring construction quality. The cooperation of the combing plate and the fixed frame can ensure that the strands are arranged neatly and limited and fixed accurately, and effectively avoid the twisting and crossing of the strands. This is crucial for the structural stability and safety of the main cable, can significantly improve the quality and performance of the main cable, and reduce the subsequent problems that may be caused by improper arrangement of the strands.

[0014] The device can adjust the action of the hydraulic cylinder and the position of the comb plate according to different strand numbers, spacing and arrangement, which makes the device adaptable to various complex construction conditions without the need for large-scale equipment modification or redesign to adapt to specific situations.

[0015] In addition, it has a positive impact on the control of construction costs. Using this device improves the efficiency of strand combing, thereby reducing labor and time costs. At the same time, high-quality strand combing can also reduce the cost of later maintenance and repair.

[0016] Finally, from a safety perspective, automated operation reduces direct human involvement in hazardous environments, lowers the risk of injury to construction workers due to improper operation, and the stable and reliable cable strand arrangement also helps ensure the safety of the entire construction process.

[0017] This automatic cable combing device for main cables achieves automated cable combing operations, significantly saving time and labor costs compared to traditional manual combing methods. The coordinated work of the hydraulic cylinder and sliding device enables the combing plate to be quickly inserted between the strands, improving the speed and accuracy of cable combing, avoiding delays and errors that may occur with manual operation, and enhancing the efficiency of the entire construction process. The sliding device allows for flexible adjustment of the positions of the hydraulic cylinder and combing plate to adapt to different construction scenarios and strand distributions, providing operators with greater convenience and flexibility, eliminating the need for frequent equipment changes or complex adjustments, and reducing the difficulty and complexity of operation.

[0018] Furthermore, the top of the comb plate is provided with inclined sections on both sides near the strands, and the top position has an arc-shaped structure. The inclined sections can play a guiding role. When the comb plate is inserted between the strands, the inclined sides can guide the strands into the correct position more smoothly, reducing the resistance and collision between the strands and the comb plate, thereby reducing the risk of strand damage. At the same time, during the combing process, a certain pressure is generated when the comb plate contacts the strands. The arc-shaped structure can make the pressure more evenly distributed on the contact surface, avoiding excessive local pressure that may cause the strands to be squeezed, deformed or damaged.

[0019] Furthermore, a groove is provided on the surface of the comb plate near the strands, and a detachable rolling device is installed in the groove. During the combing process, the contact between the strands and the comb plate generates friction. The presence of the rolling device changes this friction from sliding friction to rolling friction, reducing friction and thus reducing strand wear and energy loss. This makes the combing operation smoother and more efficient. When the rolling device malfunctions or wears out, it can be easily disassembled and replaced without replacing the entire comb plate, reducing maintenance costs and time. In addition, different types or specifications of rolling devices can be selected to be installed according to different strand specifications and construction requirements to adapt to diverse work needs.

[0020] Furthermore, the rolling device includes a support frame that mates with the groove, a fixing frame for limiting and fixing, and multiple rollers arranged in an array. These rollers are mounted on the support frame via a rotating shaft and are detachable. The distance between the rollers is less than the diameter of the strand. During long-term use, the rollers may experience wear or damage, affecting their performance. The detachable design allows for replacement of only the faulty roller, rather than the entire rolling device, saving costs and maintenance time. The array of rollers distributes the pressure between the strand and the comb plate more evenly, resulting in a relatively smaller load on each roller and extending its service life. Furthermore, when the distance between the rollers is less than the diameter of the strand, the strand can be stably placed on the roller, ensuring that the strand remains within the roller's support range and preventing it from slipping out of the gaps during conveying or combing, thus ensuring the continuity and stability of the entire combing process.

[0021] Furthermore, after the rolling device is embedded in the groove, the rotating surface of the roller protrudes from the comb plate surface. The protruding rotating surface of the roller can contact the strands earlier, thus playing a role in rolling resistance reduction in the initial stage between the insertion of the comb plate into the strands. This makes the entire combing process smoother, reduces the resistance during initial insertion and the potential damage to the strands. The protruding rotating surface of the roller can better guide the strands into the correct position, improve the accuracy and efficiency of combing, and ensure that the strands can be combed according to the predetermined trajectory and arrangement.

[0022] Furthermore, a limiting block is provided on the fixed frame, which corresponds to the rotating shaft on the support frame. The fixed frame is fastened to the support frame. The limiting block can effectively position and restrict the rotating shaft, preventing axial movement or dislocation of the rotating shaft during operation, thereby ensuring that the roller can rotate stably and guaranteeing the normal operation and reliability of the rolling device.

[0023] Furthermore, both sides of the comb plate in contact with the strands and the roller are coated with a wear-resistant protective coating. This wear-resistant protective coating is a graphene composite ceramic coating, and a fluoropolymer-nanographene hybrid coating is set on the outside of the protective coating. The simultaneous application of this coating on both sides of the comb plate in contact with the strands and the roller achieves comprehensive protection. The graphene composite ceramic coating greatly enhances the wear resistance of these components. Whether the comb plate is in repeated combing action or the roller is in contact with the strands, wear can be significantly reduced, service life can be extended, and replacement frequency and cost can be reduced. The low coefficient of friction and self-lubricating properties of the fluoropolymer-nanographene hybrid coating not only greatly reduce the friction between the comb plate and the strands, but also make the rotation of the roller smoother. This not only improves the efficiency and accuracy of combing, but also further reduces the possibility of strands being damaged by friction.

[0024] Furthermore, the hydraulic cylinder is an individually controlled hydraulic cylinder, and it is a self-locking hydraulic cylinder. The individually controlled hydraulic cylinder can achieve independent and precise operation of each combing plate. It can flexibly adjust the independent control of each combing plate according to the position and arrangement of different strands, thereby improving the accuracy and adaptability of combing and better coping with complex and ever-changing strand distribution. Moreover, the self-locking hydraulic cylinder can self-lock after completing the action of pushing the combing plate, keeping the position of the combing plate stable and preventing the combing plate from moving unexpectedly due to external force or system pressure fluctuations during the combing process. This ensures the accuracy and stability of the combing position, thereby improving the combing quality.

[0025] Furthermore, the lower end of the hydraulic cylinder is provided with a sliding device, which is connected to the fixed seat through a slide rail. The sliding device is a horizontally sliding structure, which allows the hydraulic cylinder to flexibly adjust its position in the horizontal direction. This can better adapt to strands with different layouts and spacings, improving the versatility and applicability of the device. By adjusting the sliding device, the combing plate can be more accurately aligned with the position between the strands, reducing inaccurate combing or difficulties caused by initial position deviation, thereby improving the efficiency and quality of combing.

[0026] Furthermore, the comb plate is made of alloy steel, which has high strength and hardness. This allows the comb plate to maintain structural stability and integrity during frequent contact with strands and under high pressure, making it less prone to deformation or damage, thereby extending the service life of the comb plate.

[0030] Figure 4 A schematic diagram of the structure of the present invention. Detailed Implementation

[0031] The reference numerals in the accompanying drawings include: base 1, fixed seat 2, slide rail 3, sliding device 4, hydraulic cylinder 5, comb plate 6, fixed frame 7, cable strand 8, inclined part 9, arc-shaped part 10, support frame 11, roller 12, rotating shaft 13, fixed frame 14, limit block 15, groove 16, rolling device 17, catwalk gate 18.

[0032] The basic implementation examples are as follows: Figures 1-4 As shown, the automatic cable combing device for the main cable strands includes a base 1, a fixed seat 2 on the base 1, and several hydraulic cylinders 5 on the fixed seat 2. The hydraulic cylinders 5 are equipped with combing plates 6. The combing plates 6 are made of chromium-molybdenum alloy steel, which has high strength and hardness. In the process of frequent contact with the cable strands 8 and bearing large pressure, they can maintain the stability and integrity of the structure and are not easy to deform or be damaged, thereby extending the service life of the combing plates 6.

[0033] The top of the comb plate 6 is provided with inclined parts 9 near the two sides of the strand 8, and the top position is an arc-shaped part 10. The inclined parts 9 can smoothly guide the strand 8 into the correct position, reduce resistance and collision, and reduce the risk of damage to the strand 8. The arc-shaped part 10 makes the pressure evenly distributed, and avoids the strand 8 from being squeezed, deformed or damaged.

[0034] A groove 16 is provided on the surface of the comb plate 6 near the strand 8. A detachable rolling device 17 is provided in the groove 16. The rolling device 17 includes a support frame 11 that is connected to the groove 16, a fixing frame 14 for limiting and fixing, and multiple rollers 12 arranged in an array. The distance between the rollers 12 is smaller than the diameter of the strand 8. The rollers 12 are mounted on the support frame 11 through a rotating shaft 13. The rollers 12 are detachable. When the rolling device 17 fails or wears out, it can be disassembled and replaced, saving costs and time. The arrayed rollers 12 distribute the pressure evenly and extend the service life.

[0035] After the rolling device 17 is embedded in the groove 16, the rotating surface of the roller 12 protrudes from the comb plate 6, allowing it to contact the strands 8 earlier. This rolling resistance reduction makes the combing process smoother, reduces initial insertion resistance and damage to the strands 8, and better guides the strands 8 into the correct position, improving combing accuracy and efficiency. When the distance between the rollers 12 is less than the diameter of the strands 8, the strands 8 can remain stable on the rollers 12, much like placing a ball on a track. If the track spacing is less than the diameter of the ball, the ball is less likely to fall through the gap between the tracks. The same applies to the strands 8. This spacing ensures that the strands 8 are always within the support range of the rollers 12, preventing them from getting stuck in the gaps between the rollers 12 during transport or combing. This ensures the continuity and stability of the entire combing process. When the comb plate 6 pushes upward, the rotating surface of the roller 12 contacts the strands 8, allowing the comb plate to move upward with reduced friction to separate the strands, thus reducing frictional damage to the comb plate and the strands.

[0036] A limit block 15 is provided on the fixed frame 14, corresponding to the rotating shaft 13 on the support frame 11. The fixed frame 14 and the support frame 11 are fastened together. The limit block 15 effectively positions and restricts the rotating shaft 13 to prevent axial movement or dislocation, ensure the stable rotation of the roller 12, and guarantee the normal operation and reliability of the rolling device 17.

[0037] Both sides of the comb plate 6 that contact the strand 8 and the roller 12 are coated with a wear-resistant protective coating. This wear-resistant protective coating is a graphene composite ceramic coating, and a fluoropolymer-nanographene hybrid coating is set on the outside of the protective coating, which enhances the wear resistance, reduces wear, extends service life, and reduces replacement frequency and cost. At the same time, the low coefficient of friction and self-lubricating properties reduce friction, make rotation smoother, improve combing efficiency and accuracy, and reduce the possibility of damage to the strand 8.

[0038] The hydraulic cylinder 5 is a separately controlled hydraulic cylinder 5 and is a self-locking hydraulic cylinder 5. It can adjust each comb plate 6 on the slide rail according to the position and arrangement of different strands 8, so as to better adapt to the distribution of strands 8. The self-locking function keeps the position of the comb plate 6 stable, preventing accidental movement caused by external force or system pressure fluctuations, and ensuring the combing quality.

[0039] A sliding device 4 is provided at the lower end of the hydraulic cylinder 5. The sliding device 4 is slidably connected to the fixed base 2 through the slide rail 3. It is a horizontally sliding structure. The horizontally sliding structure allows the hydraulic cylinder 5 to flexibly adjust its position to adapt to different layouts and spacings of the strands 8, thereby improving the versatility and applicability of the device. By adjusting the sliding device 4, the combing plate 6 can be more accurately aligned with the position between the strands 8, reducing inaccurate combing or difficulties caused by initial position deviation, and improving combing efficiency and quality.

[0040] A fixing frame 7 is provided on one side of the comb plate 6, and the strands 8 are set on the fixing frame 7. During the combing process, the fixing frame 7 and the comb plate 6 fix and limit the arrangement of multiple strands 8, effectively preventing the strands 8 from twisting and crossing, and ensuring that the strands 8 are neatly arranged.

[0041] In actual use, the device is placed in the construction area of ​​the main cable strand 8, the equipment is started, and when the gap between the strands needs to be adjusted according to the distribution of the strands 8, the position of the hydraulic cylinder 5 and the comb plate 6 is adjusted by the sliding device 4. Then, each hydraulic cylinder 5 is controlled individually to push the comb plate 6 to insert between the strands 8, and the multiple strands 8 are separated by the comb plate 6.

[0042] During construction, the operators first adjust the position of the hydraulic cylinder 5 according to the layout and spacing of the strands 8 using the sliding device 4. Then, the hydraulic cylinder 5 is activated, and the comb plate 6 is smoothly inserted between the strands 8 under the push of the hydraulic cylinder 5. The inclined part 9 and the arc structure effectively guide the strands 8 into the correct position. The rolling device 17 greatly reduces frictional resistance, and the protective coating protects the comb plate 6 and strands 8 from wear. Since the hydraulic cylinder 5 can be controlled and self-locked independently, the position and force of the comb plate 6 can be precisely adjusted, ensuring the neat arrangement of the strands 8 and improving construction efficiency. The combing work that originally required many people and many days can now be completed by only a few operators in a short time.

[0043] Example 2

[0044] The similarities with Example 1 will not be repeated here, such as... Figure 4 As shown, a hydraulic cylinder is installed on the catwalk gantry. This cylinder is fixedly connected to the cable guide plate, and by pulling the cable guide plate upwards, its lifting height can be precisely controlled. For example, in scenarios requiring high-precision cable strand combing, the hydraulic cylinder's stroke can be adjusted to raise the cable guide plate to a specified height based on factors such as the strand diameter, material, and combing requirements. This ensures the strands are combed under appropriate tension and position, reducing the likelihood of incomplete or damaged combing due to inaccurate cable guide plate positioning. This stable pulling force helps maintain the cable guide plate's smooth ascent. For instance, when heavy strands are placed on the cable guide plate or significant resistance is encountered during combing, the hydraulic cylinder can continuously output sufficient pulling force to ensure the cable guide plate does not stall or descend due to insufficient force, guaranteeing smooth cable combing operations.
