Abstract
Description
Technical Field
[0001] This application relates to the field of bridge construction technology, specifically to an adaptive smart catwalk wire rope. Background Technology
[0002] During the construction of the suspension bridge, a temporary construction access road, known as a catwalk, is erected. The catwalk is a linear temporary construction access road erected under and parallel to the main cables during suspension bridge construction. Construction workers use the catwalk to complete various construction tasks, including cable strand pulling, strand adjustment, saddle shaping, cable tightening, cable clamping and suspender installation, box girder hoisting and site connection, main cable winding, and protective coating.
[0003] Catwalks are important temporary structures on suspension bridges, serving as temporary construction access routes to facilitate worker access during suspension bridge erection. Catwalk erection utilizes tools such as winches, wire ropes, and chain hoists for rapid completion. Wire ropes are helical bundles of steel wires with specific mechanical properties and geometric dimensions twisted together according to certain rules. They consist of steel wires, a core, and lubricant. Wire ropes are made by first twisting multiple layers of steel wires into strands, then winding a certain number of strands around the core to form a helical shape. In material handling machinery, they are used for lifting, traction, tensioning, and load-bearing. Wire ropes are characterized by high strength, light weight, stable operation, and resistance to sudden breakage, ensuring reliable operation.
[0004] As a temporary facility in suspension bridge construction, the safety of catwalk steel cables is paramount. Although the design and construction of catwalks require sufficient strength and wind resistance, safety challenges may still arise in actual use, especially under strong winds or extreme weather conditions. The stability of the catwalk steel cables may be affected, increasing safety risks for construction workers. Furthermore, the susceptibility to corrosion and poor fire resistance of catwalk steel cables are becoming increasingly prominent issues. Currently, there are technologies for real-time cable monitoring, but these are mainly used for permanent structures such as stay cables. The structure of these cables differs from that of catwalk steel cables. Catwalk steel cables can experience torsional deformation during use. If arranged according to the structure of conventional intelligent cables, the internal signal acquisition optical fibers and other structures may be damaged due to torsion, making it difficult to achieve the required information acquisition effect. Therefore, there is a need to develop an intelligent catwalk steel cable for suspension bridges. This intelligent catwalk steel cable can monitor the cable's own physical parameters such as stress, strain, temperature, and humidity in real time, and provide real-time warnings. It can adapt to problems such as torsional deformation, ensuring the safety of construction workers and minimizing property damage. Summary of the Invention
[0005] The purpose of this application is to address the shortcomings of the aforementioned background technology and provide an adaptive smart catwalk steel wire rope.
[0006] The technical solution of this application is: an adaptive intelligent catwalk steel wire rope, comprising,
[0007] The central strand includes a core strand located at the axis and multiple drive strands circumferentially surrounding the outer side of the core strand; a continuous fiber optic sensor for monitoring the wire rope is installed inside the core strand; the drive strands are drively connected to the core strand and drive the core strand to rotate around the axis when subjected to external torsion.
[0008] Multiple common shares, wherein the multiple common shares are arranged in a circumferential manner around the outer side of the central share to form a wire rope structure;
[0009] The central stock is rotatable around its own axis and is connected to multiple ordinary stocks.
[0010] According to the adaptive smart catwalk steel wire rope provided in this application, the transmission strand is a bar-shaped gear arranged in the axial direction parallel to the core strand and capable of rotating around its own axis; a rack structure that meshes with the gear is provided on the outer circumference of the core strand.
[0011] According to the adaptive smart catwalk steel wire rope provided in this application, the central strand further includes carbon fiber cloth; the carbon fiber cloth is wrapped around the outside of all gears to press the gears tightly against the core strand so that the gears mesh tightly with the rack structure.
[0012] According to the adaptive smart catwalk steel wire rope provided in this application, the core strand and the gear are filled with lubricating oil.
[0013] According to the adaptive smart catwalk steel wire rope provided in this application, the outer side of the optical fiber sensor is wrapped with a curing adhesive to form a monitoring strand at the core strand axis.
[0014] According to the adaptive smart catwalk steel wire rope provided in this application, the fiber optic sensor includes a strain fiber for acquiring the stress of the steel wire rope and a temperature and humidity fiber for acquiring the temperature and humidity of the steel wire rope; the strain fiber and the temperature and humidity fiber are arranged symmetrically around the monitoring strand axis, and a thin steel plate is provided between the strain fiber and the temperature and humidity fiber to serve as a separator.
[0015] According to the present application, an adaptive smart catwalk steel wire rope is provided, wherein the steel wire rope comprises multiple segments, and adjacent segments are connected into one unit by a connecting structure.
[0016] According to the present application, an adaptive smart catwalk wire rope is provided, wherein the connection structure includes a flange disposed at the axial end of a segment, and adjacent segments are connected as one unit in the axial direction by bolts passing through the flange.
[0017] According to the adaptive smart catwalk wire rope provided in this application, the flange is fixedly connected to the end of the ordinary strand inside the segment by molten aluminum poured on the flange.
[0018] According to the adaptive smart catwalk steel wire rope provided in this application, the fiber optic sensors of adjacent segments are connected into one piece by fusion splicing.
[0019] The advantages of this application are as follows: 1. The catwalk steel wire rope constructed in this application can monitor the steel wire rope in real time by setting fiber optic sensors. It can obtain various parameters of the current catwalk steel wire rope in real time, and can issue early warnings when problems occur in the steel wire rope, so as to ensure the safety of construction personnel and minimize property losses. At the same time, the catwalk steel wire rope of this application is equipped with a transmission structure in the core strand. The transmission structure can convert the torsional force of the catwalk steel wire rope into the force that drives the core strand to rotate. The core strand can rotate on its own, thereby avoiding damage to the internal fiber optic sensors. It can adapt to various application scenarios of the catwalk steel wire rope, accurately monitor the steel wire rope, is not easily damaged, and has great promotional value.
[0020] 2. The transmission structure built on the outside of the core strand in this application is extremely simple. The core strand and the transmission strand are designed as a gear and rack transmission structure. When the wire rope is subjected to external torsion, the transmission strand transmits the torsion force on the wire rope to the core strand, which can drive the core strand to rotate around the axis. The fiber optic sensor inside the core strand will rotate with it and will not be damaged by torsion. Its structure is simple, has good force, excellent adaptability, and is very easy to assemble.
[0021] 3. In this application, carbon fiber cloth is wrapped around the outside of the central strand. The carbon fiber cloth can tightly connect the transmission strand and the core strand, making the gear and rack structure more closely matched. The torsional force of the wire rope can be easily transmitted to the core strand through the transmission strand. The core strand can better dissipate the torsional force and is less likely to cause the fiber optic sensor to twist and deform.
[0022] 4. This application fills the space between the core strand and the transmission strand with lubricating oil. The lubricating oil makes the meshing transmission structure between the core strand and the transmission strand smoother, the rotation between the transmission strand and the core strand is smoother, the rotation between them is less likely to be damaged, and the structural stability is better.
[0023] 5. This application uses a curing adhesive to encapsulate the fiber optic sensor, forming a monitoring strand at the axial position of the core strand. The arrangement of the fiber optic sensor is very simple. The connection between the fiber optic sensor and the core strand is flexible, with a good stress structure, which can effectively buffer various impacts and is not easily damaged.
[0024] 6. The fiber optic sensor of this application includes strain fiber and temperature and humidity fiber, which can monitor various application parameters of the wire rope. The use status of the wire rope can be obtained in real time through the strain fiber and temperature and humidity fiber, and timely warning can be given to avoid safety accidents. The arrangement structure of the strain fiber and temperature and humidity fiber avoids mutual interference.
[0025] 7. The wire rope of this application is made up of multiple segments connected axially. The wire rope is divided into multiple segments, which makes production and assembly easier. Moreover, it can prepare wire ropes that meet the length requirements according to the needs, which greatly reduces the difficulty of wire rope production, manufacturing and assembly.
[0026] 8. The method of connecting adjacent segments in this application is very simple. By setting flanges at the ends of the segments, adjacent segments are connected using adjacent flanges. The overall assembly is very simple, the segment connection strength is high, and the stress performance is good.
[0027] 9. The flange connection method of this application is very simple. By casting molten aluminum into the steel wire of the ordinary strand and fixing it to the flange, the flange can be easily installed at the end of the segment, and subsequent segment connection becomes easier.
[0028] 10. This application connects adjacent fiber optic sensors together by fusion splicing, forming a continuous fiber optic sensor arrangement within the steel wire rope. The assembly of the segments is very easy and does not affect the arrangement of the fiber optic sensors within the steel wire rope.
[0029] The catwalk wire rope of this application has a simple structure, and is very easy to install, manufacture and assemble. It can monitor the wire rope in real time, issue early warnings in a timely manner, remind users and avoid safety accidents.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

Therefore, they should not be construed as limitations on this application.
[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0039] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0040] This application relates to an adaptive intelligent catwalk steel cable. The steel cable incorporates an internal fiber optic sensor, which can collect data on the cable in real time. Analysis of this data allows for accurate assessment of the cable's current condition and timely warnings in case of problems, ensuring worker safety and minimizing property damage. Furthermore, the core strand of the steel cable with the internal fiber optic sensor rotates around its own axis when subjected to torsion, dissipating the external torsional force. This prevents the fiber optic sensor from becoming entangled and damaged, ensuring it remains in optimal working order and continuously collects data, thus adapting to various application scenarios.
[0041] Specifically, such as Figures 1-5As shown, the smart catwalk steel wire rope of this embodiment includes a central strand and multiple ordinary strands 1. The central strand includes a core strand 2 located at the axis and multiple drive strands 3 circumferentially surrounding the outer side of the core strand 2. A continuous fiber optic sensor for monitoring the steel wire rope is installed inside the core strand 2. The drive strands 3 are connected to the core strand 2 and drive the core strand 2 to rotate around its axis when subjected to external torsion. The central strand is the cable located at the axis of the entire steel wire rope and serves as the monitoring unit for the entire steel wire rope. It collects information such as stress, strain, temperature, and humidity of the steel wire rope in real time through fiber optic sensors. Based on this collected data, the usage status of the steel wire rope is determined. Data receiving devices are installed at both ends of the fiber optic sensors within the central strand. The data collected by the fiber optic sensors is transmitted to the data receiving devices for data processing. The core strand 2 and the transmission strand 3 within the central strand are connected by transmission. The core strand 2 can rotate around the axis within the area surrounded by the transmission strand 3. That is, the core strand 2 can rotate relative to the entire wire rope. This rotation can eliminate the torsional effect of the wire rope and prevent the core strand 2, which has fiber optic sensors installed inside, from being damaged due to following the torsion of the wire rope. The rotation of the wire rope and the core strand 2 around the axis is asynchronous.
[0042] The wire rope of this application has multiple ordinary strands 1 arranged around the circumference of the central strand. These ordinary strands 1 form a wire rope structure by circumferentially surrounding the central strand. The central strand is rotatable around its own axis and connected to the multiple ordinary strands. Each ordinary strand 1 is a cable structure formed by multiple wire ropes wound together. The arrangement of these ordinary strands around the central strand forms a catwalk wire rope. The ordinary strands 1 are the load-bearing part of the entire catwalk wire rope. The central strand is a structure that is rotatably connected within the ordinary strands 1. Both ends of the central strand are free ends, meaning that the rotation of the central strand is relatively independent of the rotation of the ordinary strands 1 around their axes. When the wire rope is subjected to circumferential torsion, the central strand will rotate relative to the ordinary strands around their axes. Meanwhile, the core strand 2 within the central strand, after being acted upon by the transmission strand 3, can also rotate around its own axis, effectively dissipating the circumferential torsion on the wire rope and reducing the likelihood of damage.
[0043] In some embodiments of this application, the structure of the transmission strand 3 described above has been optimized. Specifically, as follows: Figure 2 and 3As shown, in this embodiment, the transmission strand 3 is a rack-shaped gear structure that can rotate around its own axis, arranged along the axial direction parallel to the core strand 2. A rack structure that meshes with the gear structure is provided on the outer circumference of the core strand 2. That is, the transmission strand 3 itself is a rack-shaped gear structure that can rotate around its own axis. When the catwalk wire rope is subjected to torsion, the ordinary strand 1 on the outer side of the transmission strand 3 exerts a squeezing or torsional force on the transmission strand 3. These forces act on the transmission strand 3 and can drive the transmission strand 3 to rotate around its own axis. The transmission strand 3 itself is connected to the core strand 2 by a gear and rack meshing transmission. The rotation of the transmission strand 3 around its own axis will drive the core strand 3 in the middle to rotate around its axis. The rotation of the core strand 3 around its axis is free-spinning and is relatively independent of the circumferential torsion of the catwalk wire rope. The fiber optic sensor inside the core strand 3 will not be damaged by torsion.
[0044] In a further embodiment of this application, the core stock 2 structure described above has been optimized, specifically, as follows: Figure 1 As shown, the outer side of the fiber optic sensor is wrapped with curing adhesive 6 to form a monitoring strand located at the axis of the core strand 2. The fiber optic sensor is fixed and molded by the curing adhesive 6 to form a strip-shaped monitoring strand. The curing adhesive 6 can protect the monitoring strand and prevent damage to the fiber optic sensor during assembly.
[0045] After the monitoring section is formed, it is fixed to the axis of the core section 2, forming the core section 2 with internal monitoring functions and an external rack structure. Then, the transmission section 3 is assembled around the core section 2, and the gear structure of multiple transmission sections 3 meshes with the rack structure on the core section 2 for transmission.
[0046] In addition, in order to facilitate the smooth meshing and transmission connection between the transmission strand 3 and the core strand 2, this embodiment fills the space between the core strand 2 and the transmission strand 3 with lubricating oil 5. Filling with lubricating oil 5 can ensure that the rotation between the core strand 2 and the transmission strand 3 is smoother and less prone to jamming or other problems.
[0047] To ensure the tight connection between the transmission strand 3 and the core strand 2, the central strand in this embodiment also includes carbon fiber cloth 4. The carbon fiber cloth 4 is wrapped around the outside of all the transmission strands 3 to press the transmission strands 3 onto the core strand 2 so that the gear structure and the rack structure mesh tightly.
[0048] In a further embodiment of this application, the above-described fiber optic sensor has been optimized, such as... Figure 1 As shown, the fiber optic sensor includes a strain fiber 8 for acquiring the stress of the wire rope and a temperature and humidity fiber 9 for acquiring the temperature and humidity of the wire rope. The strain fiber 8 and the temperature and humidity fiber 9 are arranged symmetrically around the monitoring strand axis, and a thin steel plate 7 is provided between the strain fiber 8 and the temperature and humidity fiber 9 to act as a separator.
[0049] The strain fiber 8 and the temperature and humidity fiber 9 are arranged at intervals, with sufficient gaps between them and separated by a thin steel plate 7, so that they will not interfere with each other. Moreover, they are fixed and restrained by curing adhesive 6, forming an integral structure. No matter how the core strand 2 is twisted, the strain fiber 8 and the temperature and humidity fiber 9 will not interfere with each other, resulting in excellent stability of data acquisition.
[0050] In some other embodiments of this application, the overall structure of the catwalk wire rope is optimized. The wire rope of this embodiment includes multiple segments. The segments of this embodiment are constructed according to the combination structure of the ordinary strand 1 and the center strand described above. Adjacent segments are connected into one piece by a connecting structure to finally form an integral catwalk wire rope.
[0051] Dividing the wire rope into multiple standard segments facilitates its production, processing, and assembly. The appropriate number of segments can be selected and assembled according to actual needs to obtain the required length of catwalk wire rope. The processing, production, and assembly of individual standard segments become much simpler.
[0052] The fiber optic sensors of adjacent segments are connected as one unit by fusion splicing. This way, only data receiving devices need to be set at both ends of the wire rope to receive the data collected by the fiber optic sensors of all segments in the wire rope.
[0053] like Figure 4 and 5 As shown, the connection structure of this embodiment includes a flange 10 disposed at the axial end of the segment, and adjacent segments are connected as one unit in the axial direction by bolts 11 passing through the flange 10. The flange 10 is fixedly connected to the end of the ordinary strand 1 inside the segment by molten aluminum poured onto the flange 10.
[0054] In actual production, the following steps can be followed:
[0055] S1, Creating Core Stocks
[0056] Based on the required diameter of the finished catwalk steel wire rope, a circular hole gear with 28 gears is customized, and a thin steel plate is used to divide the hollow circular hole into two halves. The strain fiber 8 and the temperature and humidity fiber 9 are embedded in the two semi-circular holes respectively, and high elastic modulus fast curing adhesive 6 is injected into the holes to form the required core strand 2 (compared to the traditional process of grooving on the steel wire, this structure places the optical fiber in the core area of the structure, which can better protect the "fragile" optical fiber).
[0057] S2, Production Center Section
[0058] The prepared core strand 2 is coiled into a roll to form a core strand wheel. Then, the core strand wheel and the customized 7 round hole gears with 18 gears (transmission strand 2) are installed on the frame of the stranding machine, and the safety pins are inserted. Finally, the core strand 2 and the transmission strand 3 are passed through the cylinder and the dividing plate in sequence to avoid crossing. The core strand 2 and the transmission strand 3 are passed through the machine body, the pre-deformer, and the pressure plate, and tied to the lead wire. After the strand rope is extended for 5 to 10 meters, the strand diameter, twist direction, twist pitch, and flatness are checked. After confirming that everything is correct, a special strand core is formed and wrapped with high-toughness carbon fiber cloth 4 and then wound into the special strand core wheel.
[0059] This special drum core can ensure that the core strand 2 rotates through the rotation of the transmission strand 3 during multiple twisting processes under external force. Since the two ends of the core strand 2 are free ends, it can be ensured that the core strand 2 rotates freely without being affected by circumferential torque. This ensures the safety of the core strand 2 and can also further improve the accuracy of radial force measurement of the wire rope.
[0060] S3, Making steel wire rope
[0061] This stage is mainly the rope-joining stage, which is divided into the first rope-joining and the second rope-joining.
[0062] First rope assembly: Install the ordinary 6-strand 29-wire rope reel (national standard) and the special core reel onto the frame of the rope machine and insert the safety pins; pass the ordinary strand 1 and the center strand through the machine body, pre-deformer, and pressure plate, and tie them to the lead wire; after the strands have been extended for 5 to 10 meters, stop the machine and check the diameter, surface, lay direction, lay pitch, and flatness. After confirming that everything is correct, take it back to the take-up reel to form multiple sections of wire rope. The 29-wire rope has a structure of 1+7+7 / 7+14.
[0063] Second rope assembly: Pour molten aluminum onto flange 10, such as... Figure 4 Point A shown is the location where the iron-aluminum alloy water is poured (corresponding to the location of ordinary strand 1), with a depth of approximately 5mm. Through cooling with the iron-aluminum alloy water, the strands of ordinary strand 1 are firmly bonded to the flange 10. Then, the flanges 10 of two adjacent sections are connected by high-strength bolts 11, and the leveling is done with anchoring adhesive to connect the two adjacent sections. The interrupted strain fiber 8 and temperature and humidity fiber 9 can be spliced together using a fiber optic fusion splicer, and the fiber break point is protected with heat shrink tubing. Finally, the smart catwalk steel wire rope is formed.
[0064] Smart steel wire ropes are designed and manufactured in a standardized manner, facilitating mass production and installation and reducing costs. They also minimize material waste and construction debris during construction.
[0065] S4, Test
[0066] This stage is mainly the finished product testing stage; first, connect the laptop to the fiber optic demodulator, then connect the fiber optic demodulator to the catwalk steel cable, and finally conduct a load test;
[0067] The specific experimental method is as follows:
[0068] S41. The catwalk wire rope is pre-tensioned through the tensioning platform three times, each time for 30 minutes.
[0069] S42. Based on 80% of the breaking load, tensioning is carried out in five stages, with each stage held for 5 minutes.
[0070] S43. After the test is completed, the tensile force is unloaded, and step S42 is repeated twice to complete the test.
[0071] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
