Catwalk load bearing cable anti-slip protection method and system

Abstract

This invention provides a method and system for anti-slip protection of catwalk load-bearing cables. Through an integrated process, it achieves closed-loop management of anti-slip protection for catwalk load-bearing cables. The anti-slip protection system is directly installed on the top of the suspension bridge tower, ensuring that all load-bearing cables pass through a fastening and clamping module and are connected to a displacement detection module, guaranteeing seamless integration of the system with the construction site. During catwalk use, the displacement detection module captures the slippage status of the load-bearing cables in real time. When the central control module determines that slippage has occurred, it immediately triggers the fastening and clamping module to clamp the load-bearing cables, forming an automated response chain of "monitoring-judgment-execution." This replaces the traditional manual inspection mode, solving the technical problems of long inspection cycles, low accuracy, and slow response speed. It eliminates monitoring blind spots and directly eliminates slippage risks through an automated response mechanism, avoiding a chain of safety hazards caused by imbalance of anchor points.

Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology, specifically relating to a method and system for anti-slip protection of catwalk load-bearing cables. Background Technology

[0002] A catwalk is a high-altitude work platform commonly used in bridge construction. In the construction of bridges, especially suspension bridges, the catwalk is erected below the main cable through cable saddles and load-bearing cables, forming a temporary construction access road that is basically parallel to the main cable. It serves as a key temporary facility for the passage of construction personnel, material transportation, and main cable erection throughout the entire construction process of the bridge superstructure, and is of great significance to the construction of the bridge.

[0003] As a crucial temporary facility for construction personnel passage, material transportation, and main cable erection, the installation of catwalks is of paramount importance. During construction, due to the randomness of construction loads and the fluctuation of wind loads, uneven stress can easily occur in different sections of the load-bearing cables. Prolonged exposure to such dynamic loads can lead to relative slippage between the load-bearing cables and the cable saddles. Under these relative slippage conditions, serious accidents such as cable anchorage loosening, displacement, and even cable breakage and catwalk collapse can occur, posing a severe safety threat to personnel and equipment. Therefore, anti-slip protection for the catwalk load-bearing cables is essential.

[0004] In the existing technology, when protecting the catwalk load-bearing cables against slippage, the main method is to conduct regular manual inspections. Measuring tools such as tape measures are used to check the positional changes of the catwalk load-bearing cables to determine whether there is slippage. Based on the judgment results, corresponding measures are taken. This method has technical problems such as long inspection cycles, low measurement accuracy, and slow response speed. Summary of the Invention

[0005] To address the issue that in the prior art, the main method for preventing slippage of catwalk load-bearing cables is manual periodic inspection, using measuring tools such as tape measures to check the positional changes of the catwalk load-bearing cables to determine if slippage has occurred, and taking corresponding measures based on the results, this method suffers from technical problems such as long inspection cycles, low measurement accuracy, and slow response speed. This invention provides a method and system for preventing slippage of catwalk load-bearing cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a method for preventing slippage of catwalk load-bearing cables, comprising:

[0008] S1: Multiple catwalk load-bearing cables are erected at the top of the suspension bridge tower via cable saddle assemblies;

[0009] S2: Fix the anti-slip protection system for the catwalk load-bearing cables in the cable saddle assembly, so that all the catwalk load-bearing cables pass through the fastening clamping module of the anti-slip protection system for the catwalk load-bearing cables, and connect the displacement detection module of the anti-slip protection system for the catwalk load-bearing cables to all the catwalk load-bearing cables.

[0010] S3: During the use of the catwalk, the displacement detection module of the catwalk load-bearing cable anti-slip protection system detects the slip parameters of all catwalk load-bearing cables in real time.

[0011] When the central control module of the catwalk load-bearing cable anti-slip protection system determines that the catwalk load-bearing cable has slipped based on the slippage parameters, it outputs a signal to the fastening and clamping module, causing the fastening and clamping module to clamp the catwalk load-bearing cable, thereby achieving anti-slip protection for the catwalk load-bearing cable.

[0012] Optionally, step S2 includes:

[0013] S2.1: Install the fastening clamping module between the cable saddle groups so that all catwalk load-bearing cables pass through the clamping channels in the fastening clamping module;

[0014] S2.2: Fix multiple rope displacement gauges in the displacement detection module onto the fastening clamping module, and connect each rope displacement gauge to the corresponding catwalk load-bearing cable through an adapter.

[0015] Optionally, step S3 includes:

[0016] S3.1: During the use of the catwalk, the displacement detection module of the catwalk load-bearing cable anti-slip protection system detects the slip parameters of all catwalk load-bearing cables in real time and transmits them to the central control module in real time.

[0017] S3.2: When the central control module determines that any catwalk load-bearing cable has slipped based on the slippage parameters, it outputs a signal to the fastening and clamping module, causing the fastening and clamping module to clamp all catwalk load-bearing cables, thereby achieving anti-slip protection for the catwalk load-bearing cables.

[0018] Optionally, step S3 further includes:

[0019] S3.3: When the central control module determines that any catwalk support cable has slipped based on the slippage parameters of all catwalk support cables, the central control module generates the corresponding slippage data and outputs a signal to the alarm display module, which then displays the slippage data of the slipped catwalk support cable in real time.

[0020] S3.4: The central control module transmits the slippage data corresponding to the slipped catwalk support cable to the storage module and stores the slippage data; the slippage data includes: the number of the slipped catwalk support cable, the time of slippage, and the amount of slippage.

[0021] Secondly, the present invention provides a catwalk load-bearing cable anti-slip protection system for implementing the above-mentioned catwalk load-bearing cable anti-slip protection method, comprising: a central control module, a fastening and clamping module, and a displacement detection module;

[0022] The fastening and clamping module has a clamping channel through which multiple catwalk load-bearing cables pass;

[0023] The displacement detection module is mounted on the fastening clamping module and is connected to each of the catwalk load-bearing cables to detect the slippage parameters of all catwalk load-bearing cables in real time during the use of the catwalk.

[0024] The central control module is electrically connected to the displacement detection module and the fastening clamping module. It is used to acquire the slippage parameters of all catwalk load-bearing cables in real time, and determine whether any catwalk load-bearing cable has slipped based on the slippage parameters. When any catwalk load-bearing cable slips, it outputs a signal to the fastening clamping module, so that the fastening clamping module clamps all the catwalk load-bearing cables in the clamping channel to achieve anti-slip protection for the catwalk load-bearing cables.

[0025] Optionally, the fastening clamping module includes a base, a channel assembly, and a clamping assembly;

[0026] The base is fixedly installed on the top of the suspension bridge tower, between the cable saddles of the cable saddle assembly;

[0027] The channel assembly is fixedly mounted on the base and forms the clamping channel, and multiple catwalk load-bearing cables pass through the clamping channel;

[0028] The clamping assembly is fixedly installed on the base, flush with the clamping channel, and partially disposed in the clamping channel. The clamping assembly is electrically connected to the central control module.

[0029] Optionally, the channel assembly includes an upper pressure plate and a lower pressure plate arranged vertically, with the clamping channel formed between the upper pressure plate and the lower pressure plate, and multiple catwalk load-bearing cables passing through the clamping channel;

[0030] The lower side of the upper bearing plate is an inclined surface;

[0031] The clamping assembly includes a friction wedge, a clamping device, and a reaction frame;

[0032] The reaction frame is fixedly mounted on the base;

[0033] The clamping device is fixedly installed on the reaction frame and is flush with the height of the clamping channel;

[0034] The friction wedge is disposed on the clamping device and partially inserted into the clamping channel, and contacts the catwalk load-bearing cable;

[0035] The friction wedge is matched with the lower side of the upper pressure plate.

[0036] Optionally, the displacement detection module includes multiple rope displacement gauges, each of which is disposed on one side of the upper pressure plate, and each rope displacement gauge corresponds to one of the catwalk load-bearing cables.

[0037] Each of the catwalk load-bearing cables is fixedly equipped with a connector;

[0038] The cable displacement gauge is connected to its corresponding catwalk load-bearing cable via an adapter.

[0039] Optionally, the lower side of the friction wedge and the upper side of the lower bearing plate both have anti-slip protrusions, and the anti-slip protrusions on the lower side of the friction wedge and the upper side of the lower bearing plate are used to abut against the catwalk load-bearing cable.

[0040] Optionally, the catwalk load-bearing cable anti-slip protection system further includes an alarm display module and a storage module, both of which are electrically connected to the central control module.

[0041] The beneficial effects of this invention are:

[0042] This invention provides a method for preventing slippage of catwalk load-bearing cables. Through an integrated process, it achieves closed-loop management of catwalk load-bearing cable anti-slip protection. The anti-slip protection system is directly installed on the top of the suspension bridge tower, ensuring all load-bearing cables pass through a fastening and clamping module and are connected to a displacement detection module, guaranteeing seamless integration of the system with the construction site. During catwalk use, the displacement detection module captures the slippage status of the load-bearing cables in real time. When the central control module determines that slippage has occurred, it immediately triggers the fastening and clamping module to clamp the load-bearing cables, forming an automated "monitoring-judgment-execution" response chain. This replaces the traditional manual inspection mode, solving the technical problems of long inspection cycles, low accuracy, and slow response speed. It eliminates monitoring blind spots and directly eliminates slippage risks through an automated response mechanism, avoiding cascading safety hazards caused by anchor point stress imbalance. Simultaneously, the systematic installation process significantly reduces the complexity of on-site commissioning, improves construction efficiency, and provides highly reliable active protection support for large-scale suspension bridge projects.

[0043] Meanwhile, the catwalk load-bearing cable anti-slip protection system provided by this invention uniformly constrains multiple load-bearing cables through a fastening clamping module, ensuring that the cable displacement meter of the displacement detection module can accurately capture single cable slippage; the central control module makes dynamic decisions based on real-time data streams, and once slippage of the catwalk load-bearing cable is detected, it immediately drives the clamping component to perform clamping action. This system forms an integrated "monitoring-control-execution" platform, eliminating the three major pain points of traditional manual inspection methods: long inspection cycle, low measurement accuracy, and slow response speed, and significantly reducing the risk of catwalk collapse caused by slippage of the catwalk load-bearing cable.

[0057] Example 1

[0058] See Figure 1 The diagram shows a method for preventing slippage of catwalk load-bearing cables according to the present invention, including: S1: erecting multiple catwalk load-bearing cables at the top of the suspension bridge tower 1 through a cable saddle assembly;

[0059] S2: Fix the anti-slip protection system for the catwalk load-bearing cables in the cable saddle assembly, so that all the catwalk load-bearing cables 5 pass through the fastening clamping module 3 of the anti-slip protection system for the catwalk load-bearing cables, and connect the displacement detection module 4 of the anti-slip protection system for the catwalk load-bearing cables to all the catwalk load-bearing cables 5.

[0060] S3: During the use of the catwalk, the displacement detection module of the catwalk load-bearing cable anti-slip protection system is used to detect the slip parameters of all catwalk load-bearing cables 5 in real time.

[0061] When the central control module of the catwalk load-bearing cable anti-slip protection system determines that the catwalk load-bearing cable 5 has slipped based on the slippage parameters, the central control module of the catwalk load-bearing cable anti-slip protection system outputs a signal to the fastening clamping module 3, so that the fastening clamping module 3 clamps the catwalk load-bearing cable 5, thereby achieving anti-slip protection for the catwalk load-bearing cable 5.

[0062] In this embodiment, a closed-loop management system for anti-slip protection of the catwalk's load-bearing cables is achieved through an integrated process. The anti-slip protection system is directly installed on the top of the suspension bridge tower, ensuring that all load-bearing cables pass through the fastening and clamping module and are connected to the displacement detection module, guaranteeing seamless integration of the system with the construction site. During the use of the catwalk, the displacement detection module captures the slippage parameters of the load-bearing cables in real time. When the central control module determines that slippage has occurred, it immediately triggers the fastening and clamping module to clamp the load-bearing cables, forming an automated "monitoring-judgment-execution" response chain. This replaces the traditional manual inspection mode, solving the technical problems of long inspection cycles, low accuracy, and slow response speed. It eliminates monitoring blind spots and directly eliminates slippage risks through an automated response mechanism, avoiding a chain of safety hazards caused by anchor point stress imbalance. Simultaneously, the systematic installation process significantly reduces the complexity of on-site commissioning, improves construction efficiency, and provides highly reliable active protection support for large-scale suspension bridge projects.

[0063] Specifically, the cable saddle assembly includes at least two cable saddles for erecting the catwalk load-bearing cables, and the anti-slip protection system for the catwalk load-bearing cables is installed between the cable saddles.

[0064] Optionally, step S2 in this invention includes:

[0065] S2.1: Install the fastening clamping module between the cable saddle groups so that all catwalk load-bearing cables pass through the clamping channels in the fastening clamping module;

[0066] S2.2: Fix multiple rope displacement gauges in the displacement detection module onto the fastening clamping module, and connect each rope displacement gauge to the corresponding catwalk load-bearing cable through an adapter.

[0067] In this embodiment, by precisely positioning the clamping channels between the cable saddle groups, the uniformity of the travel paths of all load-bearing cables is ensured, eliminating monitoring interference caused by uneven stress on multiple cables. The design of one-to-one connection between the pull rope displacement gauge and the load-bearing cable, combined with the adapter, enables independent acquisition of displacement data of the catwalk load-bearing cables, eliminating crosstalk between multiple cables and ensuring data authenticity.

[0068] Optionally, step S3 in this invention includes:

[0069] S3.1: During the use of the catwalk, the displacement detection module of the catwalk load-bearing cable anti-slip protection system detects the slip parameters of all catwalk load-bearing cables in real time and transmits them to the central control module in real time.

[0070] S3.2: When the central control module determines that any catwalk load-bearing cable has slipped based on the slippage parameters, it outputs a signal to the fastening and clamping module, causing the fastening and clamping module to clamp all catwalk load-bearing cables, thereby achieving anti-slip protection for the catwalk load-bearing cables.

[0071] In this embodiment, the displacement detection module continuously uploads the slippage parameters of each load-bearing cable to the central control module. Through real-time data stream analysis, the central control module can accurately identify abnormal slippage of a single load-bearing cable (such as local instability caused by loose anchor points) and immediately send corresponding instructions to the clamping module to clamp the catwalk load-bearing cable for anti-slip protection, preventing further slippage. This "single-point trigger, global response" strategy avoids protection delays caused by missed detections and prevents secondary risks caused by stress redistribution by simultaneously clamping all load-bearing cables. This embodiment solves the shortcomings of existing technologies that rely on manual inspection and anti-slip protection, resulting in slow response and poor accuracy, providing proactive safety assurance for catwalk operators and equipment.

[0072] Optionally, step S3 in this invention further includes:

[0073] S3.3: When the central control module determines that any catwalk support cable has slipped based on the slippage parameters of all catwalk support cables, the central control module generates the corresponding slippage data and outputs it to the alarm display module. The alarm display module displays the slippage data corresponding to the slipped catwalk support cable in real time.

[0074] S3.4: The central control module transmits the slippage data corresponding to the slippage of the catwalk support cable to the storage module and stores the slippage data. The slippage data includes: the number of the slippage catwalk support cable, the slippage parameters, and the slippage occurrence time.

[0075] In this embodiment, when the catwalk load-bearing cable slips, the central control module synchronously drives the alarm display module to alarm and display in real time, intuitively showing the slipped load-bearing cable number, slippage parameters, and occurrence time, guiding staff to quickly locate the fault point so as to quickly arrive at the scene for fault investigation and maintenance; the storage module automatically archives complete slippage data to form a structured safety log, which not only shortens the fault response time, but also provides data support for later analysis of slippage patterns (such as the cumulative effect of wind load), and can also allow staff to optimize the catwalk load-bearing cable setting strategy by tracing back historical data, thereby improving the safety management level of the catwalk throughout its entire life cycle.

[0076] Example 2

[0077] Secondly, referring to Figures 2 to 5 The present invention provides a catwalk load-bearing cable anti-slip protection system for implementing the catwalk load-bearing cable anti-slip protection method in Embodiment 1, comprising: a central control module, a fastening clamping module 3 and a displacement detection module 4;

[0078] The fastening and clamping module 3 has a clamping channel 31 through which multiple catwalk load-bearing cables 5 pass;

[0079] The displacement detection module 4 is installed on the fastening and clamping module 3 and is connected to each catwalk load-bearing cable 5 to detect the slippage parameters of all catwalk load-bearing cables 5 in real time during the use of the catwalk.

[0080] The central control module is electrically connected to the displacement detection module 4 and the fastening clamping module 3. It is used to acquire the slippage parameters of all catwalk load-bearing cables 5 in real time, and to determine whether any catwalk load-bearing cable 5 has slipped based on the slippage parameters. When any catwalk load-bearing cable 5 slips, it outputs a signal to the fastening clamping module 3, so that the fastening clamping module 3 clamps all the catwalk load-bearing cables 5 in the clamping channel 31 to achieve anti-slip protection for the catwalk load-bearing cables 5.

[0081] In this embodiment, the fastening and clamping module 3 uniformly constrains multiple catwalk load-bearing cables 5, ensuring that the cable displacement meter of the displacement detection module 4 can accurately capture the slippage parameters of a single cable. The central control module makes dynamic decisions based on real-time data streams. Once it is determined that the catwalk load-bearing cable 5 has slipped, it immediately drives the clamping component to perform a clamping action. This system forms an integrated "monitoring-control-execution" platform, eliminating the pain points of long inspection cycles, low measurement accuracy, and slow response speed in traditional manual inspection methods, and significantly reducing the risk of catwalk collapse caused by slippage of the catwalk load-bearing cables.

[0082] Furthermore, in this embodiment, the central control module is a PLC, DCS, or other industrial central processing unit.

[0083] Optionally, refer to Figure 3 The fastening and clamping module 3 in this invention includes a base 32, a channel assembly 33, and a clamping assembly 34;

[0084] The base 32 is fixedly installed on the top of the suspension bridge tower 1, between the cable saddles 2 of the cable saddle group;

[0085] The channel assembly 33 is fixedly mounted on the base 32 and forms a clamping channel 31, through which multiple catwalk load-bearing cables 5 pass;

[0086] The clamping assembly 34 is fixedly installed on the base 32, flush with the clamping channel 31, and partially disposed in the clamping channel 31. The clamping assembly 34 is electrically connected to the central control module.

[0087] In this embodiment, the base 32 can be directly anchored to the top of the suspension bridge tower 1, providing rigid support for the system; the clamping channel 31 supports multiple load-bearing cables, limiting their non-axial displacement; the clamping component 34 is semi-embedded in the clamping channel, allowing it to quickly intervene in the clamping surface of the catwalk load-bearing cable 5, simplifying the installation process through the integration of the base 32; the flush layout of the clamping component 34 and the clamping channel 31 ensures uniform transmission of clamping force. When any catwalk load-bearing cable 5 slips, the clamping component 34 clamps into the clamping channel 31, working with the channel component 33 to clamp the catwalk load-bearing cable 5 to prevent further slippage and other risks.

[0088] Optionally, refer to Figure 3 The channel assembly 33 in this invention includes an upper pressure plate 331 and a lower pressure plate 332 arranged vertically, and a clamping channel 31 is formed between the upper pressure plate 331 and the lower pressure plate 332. Multiple catwalk load-bearing cables 5 pass through the clamping channel 31. The lower side of the upper pressure plate 331 is an inclined surface.

[0089] The clamping assembly 34 includes a friction wedge 341, a clamping device 342, and a reaction frame 343; the reaction frame 343 is fixedly mounted on the base 32; the clamping device 342 is fixedly mounted on the reaction frame 343 and is flush with the height of the clamping channel 31; the friction wedge 341 is mounted on the clamping device 342 and is partially inserted into the clamping channel 31 and contacts the catwalk load-bearing cable 5; the friction wedge 341 matches the lower side of the upper pressure plate 331.

[0090] In this embodiment, the clamping channel 31 is composed of an upper pressure plate 331 and a lower pressure plate 332, with a space between them to accommodate the catwalk load-bearing cable 5. The friction wedge 341 is inserted into the clamping channel 31 under the drive of the tightening device 342. The inclined surface of the friction wedge 341 matches the inclination angle of the upper pressure plate 331 to form a self-locking clamping structure. When the friction wedge 341 contacts the catwalk load-bearing cable 5, the inclined surface generates a radial component force to increase the clamping friction. At the same time, the reaction frame 343 provides stable support for the tightening device 342 to ensure that the pushing force is completely converted into anti-slip braking force.

[0091] Furthermore, both the upper pressure plate 331 and the lower pressure plate 332 are fixedly installed on the base 32 by brackets.

[0092] Furthermore, in this embodiment, the clamping device 342 is a hydraulic jack.

[0093] Optionally, refer to Figure 4 The friction wedge 341 and the upper side of the lower pressure plate 332 in this invention have anti-slip protrusions 35. The anti-slip protrusions on the lower side of the friction wedge 341 and the upper side of the lower pressure plate 332 are used to abut against the catwalk load-bearing cable 5.

[0094] In this embodiment, the lower side of the friction wedge 341 and the upper side of the lower pressure plate 332 have anti-slip protrusions 35, which enhance the friction between the lower side of the friction wedge 341 and the upper side of the lower pressure plate 332 and the catwalk load-bearing cable 5 during the clamping process, prevent the catwalk load-bearing cable 5 from slipping, and enhance safety.

[0095] Optionally, the displacement detection module 4 in this invention includes multiple draw-wire displacement gauges 41, as shown in the reference. Figure 3 Multiple pull rope displacement gauges 41 are installed on one side of the upper pressure plate 331, and each pull rope displacement gauge 41 is installed in a corresponding manner to the catwalk load-bearing cable 5. Each catwalk load-bearing cable 5 is fixedly equipped with an adapter 51. The pull rope displacement gauge 41 is connected to its corresponding catwalk load-bearing cable 5 through the adapter 51.

[0096] In this embodiment, the pull rope displacement meter 41 is arranged in a one-to-one correspondence with the catwalk load-bearing cable 5, so as to realize the separate detection of multiple catwalk load-bearing cables 5 and prevent mutual interference leading to misjudgment; the upper bearing plate 331 serves as the mounting base of the pull rope displacement meter 41, and its horizontal stiffness ensures the stability of the measurement reference.

[0097] Specifically, in the initial state, the pull rope of the pull rope displacement meter 41 is connected to the adapter 51. When the catwalk load-bearing cable 5 slips, that is, when the catwalk load-bearing cable 5 moves in any direction along the axial direction, the pull rope of the pull rope displacement meter 41 is stretched or retracted under the drive of the adapter 51. This will cause the pull rope displacement meter 41 to detect the movement data of the catwalk load-bearing cable 5. At this time, the central control module determines that the catwalk load-bearing cable 5 has slipped based on the obtained movement data of the catwalk load-bearing cable 5, and starts the clamping device 342. The clamping device 342 drives the friction wedge 341 into the clamping channel 31, which cooperates with the upper pressure plate 331 and the lower pressure plate 332 to clamp all the catwalk load-bearing cables 5 and prevent them from slipping further.

[0098] Optionally, the catwalk load-bearing cable anti-slip protection system of the present invention further includes an alarm display module and a storage module, both of which are electrically connected to the central control module.

[0099] In this embodiment, the system safety closed loop is improved by using an alarm display module and a storage module. The alarm module can locate the faulty load-bearing cable in real time through sound and light signals and a graphical interface, guiding staff to make precise rectifications. The storage module automatically archives slippage event data to form a traceable safety database. High-frequency slippage points can be identified through historical data analysis, guiding targeted reinforcement.
