Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction and relates to an automatic combing device for main cable strands. Background Art

[0002] The main cable is a key load-bearing component of a suspension bridge, and the regularity of its cable strands plays a vital role in the overall structural performance and service life of the suspension bridge. During the installation of the main cable of a suspension bridge, the cables composed of many high-strength steel wires need to be precisely arranged and combined to ensure that the mechanical properties of the main cable are uniform and stable and meet the design requirements.

[0003] In the process of production and actual use, due to the large number of strands and their long length, if they are not effectively arranged, the strands are prone to twisting and crossing. These problems will lead to uneven force on the main cable and local stress concentration, which will seriously affect the structural safety and durability of the suspension bridge. For example, the twisting of the strands may increase the friction between the steel wires, accelerate the wear and fatigue damage of the steel wires; and the crossing will destroy the mechanical transmission path originally designed for the strands, reducing the load-bearing capacity and overall stiffness of the main cable.

[0004] After searching and consulting relevant materials, the main solution to the above-mentioned cable strand twisting and crossing problems is to use cable combing plates to separate the cables into groups. When the main cable is installed, the cable combing plates are installed at a predetermined position to limit the displacement of the cables and maintain their relative position relationship. For example, in some early suspension bridge construction, a simple cable combing plate device was used in the main cable construction. This cable combing plate is a flat structure. The cable strands are separated by pre-setting a slot on the main cable and inserting the cable combing plate into the slot. However, this method is prone to deviation in the installation position of the cable combing plate during actual operation, thereby affecting the arrangement effect of the cable strands. Moreover, in the process of arranging the cable strands, the cable combing plate is mainly moved between the cable strands by manual knocking. Although manual knocking of the cable strands into the main cable can achieve the position of the cable strands to a certain extent, it has many disadvantages. It is difficult to accurately control the force and direction of manual knocking, which can easily damage the protective coating on the surface of the cable strands and reduce the anti-corrosion performance of the cable strands. At the same time, manual operation is inefficient and labor-intensive, and with the accumulation of construction errors, it is easy to cause an increase in the overall deviation of the cable strand arrangement, affecting the quality of the main cable.

[0005] In summary, the existing method of using a combing plate to separate the strands and manually knocking the strands into the main cable has solved the problem of strand twisting and crossing to a certain extent, but it has the disadvantages of difficult to control accuracy, easy damage to the strands, low efficiency, high labor intensity, etc. Therefore, it is necessary to develop an automatic combing device for main cable strands to overcome the shortcomings of the existing technology and realize efficient, accurate and non-destructive combing of main cable strands. Summary of the invention

[0006] The present invention provides an automatic cable combing device for main cable strands, which solves the problem of cable combing efficiency, reduces labor intensity, changes the current situation of low efficiency and high labor intensity of the existing manual knocking method, realizes the automation and efficiency of the main cable strand combing process, so as to meet the needs of large-scale suspension bridge construction and reduce construction costs.

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

[0008] The automatic combing device for main cable strands comprises a base, a fixing seat is arranged on the base, and a plurality of hydraulic cylinders are arranged on the fixing seat; a combing plate is arranged on the hydraulic cylinder, and the combing plate is not directly connected to the hydraulic cylinder, and the combing plate is pushed into between the cable strands for separation and positioning through the extension and contraction of the hydraulic cylinder; a fixing frame is arranged on one side of the combing plate, and the cable strands are arranged on the fixing frame, and a plurality of cable strands are arranged and fixed by the fixing frame and the combing plate.

[0009] The principle of this solution is that the fixed seat provides a stable supporting foundation for the entire device, and there is no direct connection between the cable combing plate and the hydraulic cylinder, so that during the cable combing operation, the device will not generate additional stress concentration and vibration transmission due to the rigid connection between the cable combing plate and the hydraulic cylinder, effectively avoiding the risk of structural damage caused by local uneven force or excessive vibration transmission. The sliding device on the fixed seat enables the hydraulic cylinder to adjust the spacing to adapt to cables with different spacing and arrangements. When combing and positioning the cable strands, the hydraulic cylinder starts and extends, and the cable combing plate is pushed upward by the hydraulic cylinder. Under the action of the hydraulic cylinder, the cable combing plate is inserted between the cable strands to separate the cable strands and achieve orderly arrangement.

[0010] The fixed frame on one side of the cable combing plate plays an auxiliary positioning role. The cable strands are limited by the fixed frame, thereby effectively preventing the cable strands from twisting and crossing, and ensuring the neat arrangement of the cable strands.

[0011] The beneficial effects of this program:

[0012] From the perspective of improving construction efficiency, this design realizes the automation of cable combing. The traditional manual combing method is not only time-consuming and labor-intensive, but also inefficient. In this device, multiple hydraulic cylinders are used to push the combing plate to separate and position the cables, greatly shortening the time required for cable combing.

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

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

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

[0016] Finally, from a safety perspective, automated operations reduce direct human involvement in dangerous environments and the risk of construction workers getting injured due to improper operation. In addition, stable and reliable cable strand arrangement also helps ensure the safety of the entire construction process.

[0017] The automatic combing device for main cable strands realizes automated combing operation, which greatly saves time and labor costs compared with traditional manual combing methods. The coordinated work of the hydraulic cylinder and the sliding device can quickly insert the combing plate between the cable strands, thereby improving the speed and accuracy of combing, avoiding delays and errors that may occur in manual operation, and improving the efficiency of the entire construction process; the sliding device allows the position of the hydraulic cylinder and the combing plate to be flexibly adjusted to adapt to different construction scenarios and cable distribution conditions, which provides greater convenience and flexibility for operators, eliminates the need for frequent equipment replacement or complex adjustments, and reduces the difficulty and complexity of operation.

[0018] Furthermore, the top position of the cable combing plate is provided with inclined portions on both side surfaces close to the cable strands, and an arc-shaped structure is provided at the top position. The setting of the inclined portions can play a guiding role. When the cable combing plate is inserted between the cable strands, the inclined side surfaces can more smoothly guide the cable strands to the correct position, thereby reducing the resistance and collision between the cable strands and the cable combing plate, thereby reducing the risk of damage to the cable strands. Meanwhile, during the cable combing process, a certain amount of pressure will be generated when the cable combing plate contacts the cable strands. The arc-shaped structure can make the pressure more evenly distributed on the contact surface, thereby preventing the cable strands from being squeezed, deformed or damaged due to excessive local pressure.

[0019] Furthermore, a groove is provided on the surface of the cable combing plate close to the cable strands, and a detachable rolling device is provided in the groove. During the cable combing process, the contact between the cable strands and the cable combing plate generates friction, and the presence of the rolling device transforms the friction from sliding friction into rolling friction, thereby reducing the friction, thereby reducing the wear and energy loss of the cable strands, making the cable combing operation smoother and more efficient, and when the rolling device fails or wears out, it can be easily disassembled and replaced without replacing the entire cable combing plate, thereby reducing maintenance costs and time. At the same time, according to different cable strand specifications and construction requirements, rolling devices of different types or specifications can be selected and installed to meet diverse work needs.

[0020] Furthermore, the rolling device comprises a support frame connected with the groove, a fixed frame fixed in position, and a plurality of rollers arranged in an array, the rollers are arranged on the support frame through a rotating shaft, and the rollers are arranged in a detachable structure, and the spacing between the rollers is smaller than the diameter of the cable strand. During long-term use, the rollers may affect the performance due to wear or damage. The detachable design allows only the roller with problems to be replaced without replacing the entire rolling device, saving costs and maintenance time. The plurality of rollers arranged in an array can more evenly share the pressure between the cable strand and the cable combing plate, so that the load borne by each roller is relatively small, thereby extending the service life of the rollers, and when the spacing between the rollers is smaller than the diameter of the cable strand, the cable strand can be stably placed on the roller, which can ensure that the cable strand is always within the support range of the roller, and avoid the cable strand from slipping from the gap between the rollers during the process of conveying or combing the cable strand, thereby 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 surface of the cable combing plate. The protruding rotating surface of the roller can contact the cable strands earlier, so that the rolling resistance reduction effect begins to be exerted in the initial stage of the cable combing plate being inserted between the cable strands, making the entire cable combing process smoother, reducing the resistance during the initial insertion and possible damage to the cable strands. The protruding rotating surface of the roller can better guide the cable strands into the correct position, improve the accuracy and efficiency of the cable combing, and ensure that the cable strands can be combed according to the predetermined trajectory and arrangement.

[0022] Furthermore, a limit block is provided on the fixed frame, and the limit block corresponds to the rotating shaft on the supporting frame. The fixed frame and the supporting frame are buckled together, and the limit block can effectively position and limit the rotating shaft to prevent axial movement or dislocation of the rotating shaft during operation, thereby ensuring that the roller can rotate stably and ensuring the normal operation and reliability of the rolling device.

[0023] Furthermore, both sides of the cable combing plate in contact with the cable strands and the roller are coated with a wear-resistant protective coating, which is a graphene composite ceramic coating, and a fluoropolymer-nanographene hybrid coating is provided outside the protective coating. This coating is applied simultaneously to both sides of the cable combing plate in contact with the cable strands and the roller, thereby achieving comprehensive protection. The graphene composite ceramic coating greatly enhances the wear resistance of these components, and can significantly reduce wear, extend service life, and reduce replacement frequency and cost, whether the cable combing plate is in repeated cable combing action or the roller is in contact and rolling with the cable strands. The low friction coefficient and self-lubricating properties of the fluoropolymer-nanographene hybrid coating not only greatly reduce the friction between the cable combing plate and the cable strands, but also make the rotation of the roller smoother, which not only improves the efficiency and accuracy of the cable combing, but also further reduces the possibility of the cable strands being damaged due to friction.

[0024] Furthermore, the hydraulic cylinder is an individually controlled hydraulic cylinder, and the hydraulic cylinder is a self-locking hydraulic cylinder. The individually controlled hydraulic cylinder can realize independent and precise operation of each cable combing plate, and can flexibly adjust the independent control of each cable combing plate according to the position and arrangement of different cable strands, thereby improving the accuracy and adaptability of the cable combing, and being able to better cope with the complex and changeable cable strand distribution conditions. In addition, the self-locking hydraulic cylinder can self-lock after completing the action of pushing the cable combing plate, thereby keeping the position of the cable combing plate stable, preventing the cable combing plate from accidentally moving due to external force or system pressure fluctuations during the cable combing process, ensuring the accuracy and stability of the cable combing position, and thus improving the quality of the cable combing.

[0025] Furthermore, a sliding device is provided at the lower end of the hydraulic cylinder, and the sliding device is slidably connected to the fixed seat through a slide rail. The sliding device is a horizontally slidable structure. The horizontally slidable structure enables the hydraulic cylinder to flexibly adjust its position in the horizontal direction, which can better adapt to cables with different layouts and spacings, thereby improving the versatility and applicability of the device. Through the adjustment of the sliding device, the cable combing plate can be more accurately aligned with the position between the cable strands, reducing the inaccuracy or difficulty of combing the cables due to initial position deviation, thereby improving the efficiency and quality of combing the cables.

[0026] Furthermore, the cable combing plate is made of alloy steel, which has high strength and hardness. This enables the cable combing plate to maintain structural stability and integrity during the working process of frequent contact with cable strands and under great pressure, and is not prone to deformation or damage, thereby extending the service life of the cable combing plate.

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

[0032] The embodiment is basically as shown in the attached Figure 1-4 As shown, the automatic combing device for main cable strands comprises a base 1, on which a fixed seat 2 is arranged, on which a plurality of hydraulic cylinders 5 are arranged, on which a combing plate 6 is arranged, and the combing plate 6 is made of chromium-molybdenum alloy steel, and has high strength and hardness. In the working process of frequent contact with the cable strands 8 and bearing high pressure, the stability and integrity of the structure can be maintained, and deformation or damage is not easy to occur, thereby extending the service life of the combing plate 6.

[0033] Inclined portions 9 are provided on both sides of the top of the cable combing plate 6 close to the cable strands 8, and the top is an arc-shaped portion 10. The inclined portions 9 can smoothly guide the cable strands 8 into the correct position, reduce resistance and collision, and reduce the risk of damage to the cable strands 8. The arc-shaped portions 10 evenly distribute the pressure to prevent the cable strands 8 from being squeezed, deformed or damaged.

[0034] A groove 16 is provided on the surface of the cable combing plate 6 close to the cable strand 8, and a detachable rolling device 17 is provided in the groove 16. The rolling device 17 includes a support frame 11 connected to the groove 16, a fixed frame 14 for limiting position and a plurality of rollers 12 arranged in an array, and the spacing between the rollers 12 is smaller than the diameter of the cable strand 8. The rollers 12 are arranged on the support frame 11 through a rotating shaft 13, and the rollers 12 are of a detachable structure. When the rolling device 17 fails or wears out, it can be disassembled and replaced, saving cost and time. The rollers 12 arranged in an array evenly share the pressure 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 surface of the combing plate 6, which can contact the cable strand 8 earlier, play a rolling resistance reduction role, make the combing process smoother, reduce the initial insertion resistance and cable strand 8 damage, better guide the cable strand 8 to the correct position, and improve the accuracy and efficiency of combing. When the spacing between the rollers 12 is smaller than the diameter of the cable strand 8, the cable strand 8 can be stably placed on the roller 12, just like placing a small ball on a track. If the interval of the track is smaller than the diameter of the small ball, the small ball is not easy to fall from the gap between the tracks, and the same is true for the cable strand 8. Such a spacing setting can ensure that the cable strand 8 is always within the support range of the roller 12, and avoid the cable strand 8 being stuck in the gap between the rollers 12 during the process of conveying or combing the cable strand 8, thereby ensuring the continuity and stability of the entire combing process. When the combing plate 6 is pushed upward, the rotating surface of the roller 12 contacts the cable strand 8, so that the combing plate can move upward to separate the cable strands while reducing the friction with the cable strand, thereby reducing the friction damage to the combing plate and the cable strand.

[0036] A limit block 15 is provided on the fixed frame 14, corresponding to the rotating shaft 13 on the supporting frame 11. The fixed frame 14 is buckled with the supporting frame 11, and the limit block 15 effectively positions and limits the rotating shaft 13 to prevent axial movement or dislocation, thereby ensuring stable rotation of the roller 12 and ensuring the normal operation and reliability of the rolling device 17.

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

[0038] The hydraulic cylinder 5 is a separately controlled hydraulic cylinder 5 and is a self-locking hydraulic cylinder 5. Each cable combing plate 6 can be adjusted on the slide rail according to the position and arrangement of different cable strands 8 to better adapt to the distribution of the cable strands 8. The self-locking function can keep the position of the cable combing plate 6 stable to prevent accidental movement caused by external force or system pressure fluctuations, thereby ensuring the quality of the cable combing.

[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 seat 2 through the slide rail 3. It is a horizontally slidable structure. The horizontally slidable structure enables the hydraulic cylinder 5 to flexibly adjust its position to adapt to cables 8 of different layouts and spacings, thereby improving the versatility and applicability of the device. Through the adjustment of the sliding device 4, the cable combing plate 6 can be more accurately aligned with the position between the cable strands 8, reducing the inaccuracy or difficulty of cable combing caused by initial position deviation, thereby improving the efficiency and quality of cable combing.

[0040] A fixing frame 7 is provided on one side of the cable combing plate 6, and the cable strands 8 are arranged on the fixing frame 7. During the cable combing process, the plurality of cable strands 8 are arranged and fixed by the fixing frame 7 and the cable combing plate 6, so as to effectively prevent the cable strands 8 from twisting and crossing and ensure that the cable strands 8 are neatly arranged.

[0041] In actual use, the device is placed in the construction area of ​​the main cable strands 8, and the equipment is started. When the gap between the strands needs to be adjusted according to the distribution of the strands 8, the positions of the hydraulic cylinders 5 and the cable combing plates 6 are adjusted through the sliding device 4, and then each hydraulic cylinder 5 is controlled individually to push the cable combing plates 6 to insert between the strands 8, so that multiple cable strands 8 are separated by the cable combing plates 6.

[0042] During the construction process, the operator first adjusts the position of the hydraulic cylinder 5 through the sliding device 4 according to the layout and spacing of the cable strands 8, and then starts the hydraulic cylinder 5. The cable combing plate 6 is smoothly inserted between the cable strands 8 under the push of the hydraulic cylinder 5. The inclined portion 9 and the arc structure effectively guide the cable strands 8 to the correct position. The rolling device 17 greatly reduces the friction resistance. The protective coating protects the cable combing plate 6 and the cable strands 8 from wear. Since the hydraulic cylinder 5 can be controlled and self-locked individually, the position and strength of the cable combing plate 6 can be accurately adjusted to ensure the neat arrangement of the cable strands 8 and improve the construction efficiency. The cable combing work that originally required many people and many days to complete can now be completed by only a few operators in a shorter time.

[0043] Embodiment 2

[0044] The same points as in Example 1 are not repeated here. Figure 4 As shown, a hydraulic cylinder is provided on the catwalk gantry, and the hydraulic cylinder is fixedly connected to the cable combing plate. The cable combing plate is pulled up by the hydraulic cylinder. By being fixedly connected to the cable combing plate and pulling it up, the rising height of the cable combing plate can be accurately controlled. For example, in some scenarios where high-precision combing of cable strands is required, the cable combing plate can be lifted to a specified height by adjusting the stroke of the hydraulic cylinder according to factors such as the diameter, material and combing requirements of the cable strands, so that the cable strands can be combed under appropriate tension and position, thereby reducing the situation where the cable strands are combed unsmoothly or damaged due to inaccurate position of the cable combing plate. In the process of pulling the cable combing plate up, this stable pulling force helps to keep the cable combing plate rising steadily. For example, when a heavy cable strand is placed on the cable combing plate or a large resistance is encountered during the combing process, the hydraulic cylinder can continuously output sufficient pulling force to ensure that the cable combing plate will not stagnate or fall due to insufficient pulling force, thereby ensuring the smooth progress of the combing work.
