Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of suspension bridge cable clamp installation equipment, and more specifically, relates to an integrated machine for cable tightening, cable clamp fastening and void ratio detection of suspension bridges and its construction method. Background Technology
[0002] Cable clamps are a crucial component of suspension bridge structures. They connect the main cables and bridge towers, bearing the weight of the bridge deck load and transferring it to the towers. They also provide support and fixation, ensuring the stability and reliability of the main cables at the towers. Adjusting the position of the cable clamps allows for control of the prestressing of the main cables and the shape of the bridge deck. Proper design and arrangement also help distribute and balance the bridge deck load, improving the structural stability and service life of the suspension bridge. Therefore, cable clamps are critical to the safety, performance stability, and operational reliability of suspension bridges. After determining the precise position and arrangement of the cable clamps on the main cables, traditional construction methods require pre-tensioning the cables to ensure a circular cross-section and a void ratio of ≤30%. Subsequent formal cable tightening further reduces the void ratio to ensure the main cables maintain appropriate tension under bridge loads, effectively bearing the load and minimizing loosening and friction between the main cables and the cable clamps, thus guaranteeing the stability and safety of the entire bridge structure.
[0003] In the prior art, Chinese Patent CN117468359A discloses an intelligent cable tensioning machine and method for the main cable of a suspension bridge, including a traveling mechanism, a tensioning device, a hydraulic pump station, a counterweight frame, a controller, and cable displacement sensors; the controller is connected to the counterweight frame; each hydraulic jack is connected to a cable displacement sensor; each cable displacement sensor and the hydraulic pump station are electrically connected to the controller. This invention uses six cable displacement sensors to actually measure three sets of diameters, and uses these three sets of diameter values to derive the real-time porosity and out-of-roundness, which are then adjusted by operating the hydraulic pump station.
[0004] Chinese patent CN117468359A improved the efficiency and accuracy of calculation by systematically calculating porosity, which greatly improved the efficiency of main cable tightening construction. However, it still did not solve some problems in the installation of cable clamps for suspension bridges: (1) During the tightening process, the single-sided cable tightening machine may cause uneven tightening of the main cable, affecting the balance and load-bearing capacity of the suspension bridge; (2) The low degree of integration of cable tightening and cable clamp installation equipment for suspension bridges makes coordination difficult, data consistency poor, and also increases the complexity of operation and construction cost; (3) During the construction of cable tightening and cable clamps, the operation platform provided by the catwalk may be limited by the structure of the suspension bridge itself, such as the distance between the main cable and the bridge deck and the height of the bridge tower. Under the condition of limited space, the construction operation may become more difficult. Summary of the Invention

The reaction frame 222 is a steel structural component that is straight at both ends and curved in the middle, forming a 90-degree angle. Its two ends are fitted with semi-circular protrusions and grooves, each with a through hole corresponding to the pin 228. These protrusions and grooves are fixedly connected through the through holes and the pin 228, allowing multiple reaction frames 222 to be combined into a circular, closed structure, forming the main structure of the cable tensioning component 220. Simultaneously, the two upper reaction frames 222 of this main structure are fixedly connected to the connector 212, thus securely set inside the cable tensioning bracket 210, ensuring the stability and safety of the cable tensioning component 220. The fourth hydraulic jack 22... The 6th hydraulic jack is cylindrical and fixed to the straight end of the reaction frame 222; the second fastening shoe 229 is an arc-shaped steel component and fixed to the end of the fourth hydraulic jack 226 facing the main cable 510, used to tighten the main cable 510; the first slider 223 is an L-shaped slider welded or integrally formed from rectangular steel plates, fixed to the upper left and right sides of the reaction frame 222 at the lower end of the main structure of the cable tightening component 220 and adapted to the first slide rail 213 to assist the horizontal movement of the lower reaction frame 222, realizing convenient disassembly and assembly of the lower end of the main structure; the connecting block 227 is a rectangular steel plate and fixed to the cable tightening component 220. The lower left and right sides of the reaction frame 222 at the lower end of the main structure of the cable component 220; the second slider 225 is an L-shaped slider welded or integrally formed from rectangular steel plates, which is fixedly installed in the middle of one side of the connecting block 227 and adapted to the second slide rail 214 to assist the horizontal movement of the lower reaction frame 222, so as to realize the convenient disassembly and assembly of the lower end of the main structure; the third hydraulic jack 224 is a cylindrical jack, which is fixedly installed at the lower end of the steel structure columns on both sides of the cable tensioning frame 211 and one end passes through the cable tensioning frame 211 and is fixedly connected to the upper outer surface of the connecting block 227, and is used to provide power for the horizontal movement of the lower reaction frame 222.
[0056] Furthermore, during construction, multiple cable tensioning units 200 are fixed inside the integrated machine through through holes 216 adapted to the first connecting beam 140, and stand facing each other with the side without the fixed walking component 130 facing each other. This method can reasonably arrange the cable clamp installation work space so that the cable clamps 520 located between the multiple cable tensioning units 200 can be installed normally. At the same time, by applying pressure or tension to both sides of the main cable 510 through the cable tensioning units 200 on both sides, the load is evenly distributed, preventing the main cable 510 from being overloaded on one side, which would lead to uneven stress and porosity distribution. This improves the durability and reliability of the cable clamp 520 installation. Moreover, the cable tensioning operations on both sides can cooperate with each other to prevent the main cable 510 from generating excessive vibration or deformation when the load changes, thereby maintaining the stability of the device or structure, reducing the risk of accidents, and improving safety.
[0057] Preferably, after the cable clamp is installed following the construction of the cable tensioning unit 200, the porosity of the main cable 510 is ≤16%.
[0058] Preferably, the width of the second fastening shoe 229 is 220-380mm.
[0059] Preferably, the cable tightening unit 200 is suitable for main cable 510 with a diameter of 1100-1550mm.
[0060] Preferably, the second hydraulic pump station 221 can control the operating status of the third hydraulic jack 224 and the fourth hydraulic jack 226.
[0061] like Figures 1 to 5As shown, the cable clamp installation unit 300 is fixedly installed on the inner side of the steel structure columns on both sides of the cable tightening unit 200. It also includes an auxiliary platform 310, a fifth hydraulic jack 320, an electric wrench 330, and cable clamp bolts 340. The auxiliary platform 310 includes a base plate mainly composed of rectangular steel plates and a steel guardrail fixed to the outer side of the base plate. One end of the guardrail is fixed to one side of the steel structural columns on both sides of the cable tensioning frame 211 and located on the opposite side of the walking component 130, for temporarily storing other cable clamp installation unit 300 components. One end of the fifth hydraulic jack 320 is adapted to the cable clamp bolt 340 and used to pre-tighten the cable clamp bolt 340. The other end of the jack is also fixedly connected to the second hydraulic pump station 221 via a cable and inputs stable hydraulic energy through the second hydraulic pump station 221. A pressure sensor for sensing hydraulic pressure is also fixedly installed at the connection point between the cable and the fifth hydraulic jack 320. At the same time, the pressure sensor can transmit pressure data to the motion controller 420. One end of the electric wrench 330 is adapted to the cable clamp bolt 340 and used to pre-tighten the cable clamp bolt. Bolt 340 is used for final tightening. During construction, the fifth hydraulic jack 320, electric wrench 330, and cable clamp bolt 340 are temporarily stored above the base plate of the auxiliary platform 310. After the cable clamp bolt 340 is placed in the appropriate position on the cable clamp 520, multiple fifth hydraulic jacks 320 form a pre-tightening device to pre-tighten multiple cable clamp bolts 340 under the hydraulic energy input from the second hydraulic pump station 221 controlled by the mobile controller 420. After pre-tightening, the electric wrench 330 replaces the fifth hydraulic jack 320 and tightens multiple cable clamp bolts 340 under the control of the mobile controller 420. This ensures that the torque value of the cable clamp bolt 340 meets the design requirements, avoids loosening and over-tightening, and controls material stress, thereby improving the reliability and safety of the cable clamp 520 and increasing the installation efficiency of the cable clamp.
[0062] Preferably, the cable clamp mounting unit 300 meets the following requirements during the tightening operation of the cable clamp bolt 340: resolution of 0.8-1.2 kN, corresponding sensor accuracy of 0.2%-0.5% FS, and system synchronization accuracy of 0.8%-1.2%.
[0063] like Figure 1 and Figure 6As shown, the detection and control unit includes a detector 410 and a motion controller 420. The detectors 410 are fixedly mounted on the lower side of one side of the support block 215 and on the same side of the steel structural columns on both sides of the cable tensioning frame 211. Multiple detectors 410 on the same side are combined to form a three-dimensional detection system, used to detect the porosity of the main cable 510 in real time and send the data to the motion controller 420 to obtain accurate real-time data. This allows for observation of the cable tensioning status and changes, helping to understand the actual working condition of the structure. Furthermore, by monitoring the porosity, potential fault signs can be detected in a timely manner, allowing for necessary maintenance and adjustment measures to avoid further structural damage and safety risks. Timely adjustment of the porosity of the main cable 510 ensures the stability and safety of the cable clamp 520 installation, extending the structural lifespan. The mobile controller 420 is a handheld, portable controller, which also includes a display terminal 421 for displaying the real-time status and operation options of the integrated machine and an input terminal 422 for controlling the operation of the entire integrated machine. During the operation of the integrated machine, the movement and operation of the integrated machine are controlled by the mobile controller 420 to realize intelligent installation operation, thereby providing greater flexibility and accuracy, reducing the risk exposure of operators, improving work efficiency, achieving precise cable tightening operation and simplifying the cable clamp installation process.
[0064] Preferably, the detectors 410 on both sides are at a lower vertical height than the main cable 510.
[0065] Preferably, the three-dimensional detection system composed of the detectors 410 can acquire data such as the longitudinal axis diameter, minor axis diameter and circumference of the main cable 510 in real time, and the data is displayed as a three-dimensional reconstruction result in the motion controller 420.
[0066] Preferably, the mobile controller 420 is connected to the walking component 130 wirelessly and / or via wired means to control the running speed and direction of the walking component 130. It is also connected to the first hydraulic pump station 115 and the second hydraulic pump station 221 wirelessly and / or via wired means to control the operating status of all jacks.
[0067] like Figure 7 and Figure 8 As shown, another embodiment of the present invention provides a construction method for an integrated machine for cable tightening, cable clamp fastening, and porosity detection of suspension bridges, comprising the following steps:
[0068] S1: Verify the cable clips and corresponding consumables and ensure their quality meets the requirements; check the operation status of the integrated machine and ensure the equipment is operating normally; develop a detailed construction plan, including workflow, schedule, personnel allocation and resource requirements;
[0069] S2: After the reaction frames 222 on the lower side of the cable tensioning unit 200 are all in a position away from the main cable 510 and the cable tensioning unit 200 is kept in the posture of crossing the cable clamp 520, the integrated machine is hoisted to the installation position of the cable clamp 520 above the main cable 510. The first hydraulic jack 113 and the second hydraulic jack 116 respectively drive the first fastening shoe 114 to stick to the main cable 510 so that the walking frame 110 maintains the posture of clamping the main cable 510. The second connecting beam 150 is installed and the installation position of the cable clamp 520 is cleaned.
[0070] S3: After the third hydraulic jack 224 operates to bring the lower reaction frame 222 horizontally close to the main cable 510 and fix it with the pin 228, the fourth hydraulic jack 226 drives the second fastening shoe 229 to press against the main cable 510, so that the cable tightening unit 200 is in the posture of squeezing the main cable 510 and the main cable 510 is tightened; at the same time, the cable clamp 520 is hoisted to the installation position and pre-fixed with the cable clamp bolt 340, and then the fifth hydraulic jack 320 is used to pre-tighten and the electric wrench 330 is used to tighten the cable clamp bolt 340 in sequence.
[0071] S4: After the cable clamp 520 is installed, remove the tightening device and verify the installation quality of the cable clamp 520; once the requirements are met, the integrated machine will move to the next cable clamp 520 installation position in a walking manner and complete the installation of the remaining cable clamps 520 using steps S2 and S3.
[0072] Specifically, the walking method described in step S4 includes the following steps:
[0073] S401: After the cable clamp 520 is installed, the cable tightening unit 200 maintains the posture of clamping the main cable 510. The first hydraulic jack 113 and the second hydraulic jack 116 respectively drive the first fastening shoe 114 away from the main cable 510 so that the walking frame 110 forms a walking posture.
[0074] S402: Multiple walking components 130 work simultaneously and drive the walking frame 110 to move along the main cable 510 axis by driving the first connecting beam 140. After the walking frame 110 approaches the cable clamping unit 200 on one side, the walking component 130 stops, and the first hydraulic jack 113 and the second hydraulic jack 116 work to keep the walking frame 110 clamping the main cable 510.
[0075] S403: After the traveling frame 110 clamps the main cable 510, the pin 228 that fixes the lower reaction frame 222 is removed. The third hydraulic jack 224 works to make the cable tensioning unit 200 cross the cable clamp 520. The traveling component 130 works to make the cable tensioning unit 200 move along the first connecting beam 140 to one side of the cable tensioning unit 200 close to one side of the traveling frame 110.
[0076] S404: After the third hydraulic jack 224 operates to keep the cable tensioning unit 200 in the position of clamping the main cable 510, repeat steps S401-S403 to move the integrated machine to the next cable clamp 520 installation position.
