Description

Technical Field

[0001] This invention belongs to the technical field of installation devices for long linear structures with large-angle vertical rotation, specifically relating to a cable tensioning device, method, and application for long linear structures with large-angle vertical rotation. Background Technology

[0002] With the continuous advancement of computer-based dynamic synchronous control technology, clustered mechanical equipment has been widely applied in civil engineering construction, with rotation technology making significant progress. Structures employing vertical rotation typically utilize a "horizontal assembly and vertical rotation" method, where the structure is assembled or prefabricated on the ground. This significantly reduces high-altitude work and lowers construction safety risks while ensuring accuracy. This technique is particularly suitable for high towers (piers), arch ribs spanning valleys and ravines, and arch ribs in continuous beam arches in railways. The vertical rotation system usually includes tie rods, compression rods, cables, backstays, bogies, hinges, jacks / cylinders, etc. However, as the tower height or the vertical rotation angle of the arch rib increases, the cable tension changes more significantly, generally decreasing or increasing with the angle.

[0003] As the vertical rotation angle increases, the stress level of the cables continuously changes. Within each cable bundle, it is highly likely that one or several strands will experience relatively low or no stress, causing them to slack and easily detach from the saddle. This introduces uncertainty regarding whether they can be successfully tightened and repositioned into the saddle during subsequent rotation, posing a safety hazard. Existing jacks / cylinders rarely have the capability to tension specific strands at the tensioning end. Furthermore, the cable anchoring end is usually positioned high up, exceeding the typical crane's working height, with a large structural elevation angle and steep slope, making it inaccessible to personnel and equipment. Therefore, the problem of individual strands experiencing relatively low or no stress cannot be effectively resolved. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a cable tensioning device, method and application for large-angle vertical rotation of long linear structures, in order to solve the problem in the prior art that individual steel strands in the cable may become slack when long linear structures are rotated at large angles, and that it is difficult to tension the slack steel strands due to the limitations of the length and installation height of the installation components.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses a cable tensioning device with a long linear structure and large-angle vertical rotation, located at the cable anchorage end of the higher end of the vertical rotation component. It includes a cable force identification module, a mechanical transmission module, and a tensioning module. The cable force identification module includes several force measuring elements, each disposed on a steel strand of the cable. The mechanical transmission module includes a three-stage rotary hinge structure for adjusting the spatial position of the end, comprising a first, second, and third rotary hinge structure connected sequentially. The tensioning module includes a fixed cylinder, a working clamp, and a telescopic cylinder. The working clamp is disposed within the fixed cylinder, and the telescopic cylinder is fixedly connected to the fixed cylinder at one end facing the cable anchorage end. The end of the first rotary hinge structure is fixed to the surface of the vertical rotation component, and the end of the third rotary hinge structure is fixed to the fixed cylinder.

[0007] Furthermore, a pressure plate module is provided at the anchoring end of the cable. The pressure plate module includes a fastening screw, a limiting pressure plate, a lower plate spring, and a lower plate clamping piece. The fastening screw fixes the limiting pressure plate to the anchoring end of the cable, and the lower plate spring and the lower plate clamping piece are disposed between the limiting pressure plate and the anchoring end of the cable.

[0008] Furthermore, a steel strand shearing structure is sleeved on the outer side of the cable anchoring end. The steel strand shearing structure includes a fixing ring, which is fixed to the cable anchoring end. At least two lifting columns are provided on the surface of the fixing ring. A lifting plate is slidably connected to the lifting column. The lifting plate has several through holes that match the steel strands in the cable. A return spring is provided on the lifting column, which is located between the fixing ring and the lifting plate. Fixed seats are symmetrically provided on the lifting plate. A telescopic rod is provided on the fixed seat. The output end of the telescopic rod is set towards the middle of the lifting plate, and a cutter is provided on the output end of the telescopic rod. Under normal conditions, the lifting plate is flush with the ends of several steel strands located outside the cable anchoring end.

[0009] Furthermore, the fixing ring is also provided with a number of limiting posts, which are evenly distributed along the circumference of the limiting ring.

[0010] This technical solution also discloses a tensioning method for a long linear structure large-angle vertical rotation cable tensioning device, including the following steps:

[0011] ① The intelligent control system determines the position where the mechanical transfer module last stopped, initializes itself, and confirms the current position coordinates;

[0012] ② Track the position coordinates of the steel strand with the minimum tension and confirm the relationship between θ, h, and r and the position coordinates of the mechanical transmission module;

[0013] ③ The mechanical transmission module starts the first rotary hinge structure to perform polar axis tracking and reach the precise directional position of the target coordinate θ component;

[0014] ④ The mechanical transmission module activates the second rotary hinge structure to perform height tracking and reach the target coordinate h component direction interval Δh and r component direction interval Δr;

[0015] ⑤ The mechanical transmission module activates the third rotary hinge structure to perform radius tracking and reach the precise directional position of the target coordinate r component;

[0016] ⑥ After the mechanical transfer module transfers the tensioning module to the locking position, the video system verifies and confirms it;

[0017] ⑦ After confirming that everything is correct, the tensioning module begins to work;

[0018] ⑧ After tensioning is completed, the mechanical transfer module is reset;

[0019] ⑨ Restart the cable force identification module to monitor the force on each steel strand of the cable in real time, and determine whether to restart the intelligent tension control system program based on the difference in cable force values.

[0020] This technical solution also discloses the application of a cable tensioning device for large-angle vertical rotation of long linear structures, which is mainly used for the installation of ultra-high towers, ultra-high piers and arch ribs with ultra-large angle vertical rotation.

[0021] The beneficial effects of this invention are as follows:

[0022] (1) The working principle of this technical solution is clear and the functional modules are reasonably divided. It directly solves the technical problem of uneven stress on the cable strands when the structure is vertically rotated to a high position and large angle that cannot be reached by personnel and machinery.

[0023] (2) The entire vertical rotation process can be completed without manual intervention, which effectively reduces the amount of high-altitude work and significantly reduces construction safety risks;

[0024] (3) It has promoted the further development of rotation technology, especially the vertical rotation of ultra-high towers (piers) and the vertical rotation of arch ribs at ultra-large angles;

[0025] (4) The present invention proposes to provide an intelligent device that can tension and tighten any single cable / steel strand at the cable anchorage end. It can monitor the cable force of each steel strand in real time. When it is found that the individual steel strands are under less force, it can selectively tension the steel strands under less force at the cable anchorage end to ensure that each steel strand in each cable bundle is under uniform force. From monitoring, identification and tensioning, no manual operation is required throughout the entire process, thereby ensuring that the structural rotation system is always safe and reliable.

[0026] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0042] like Figures 1-8 As shown, this invention discloses a cable tensioning device for a long linear structure with a large-angle vertical rotation. The device is located at the cable anchorage end 1, which is at a higher position on the vertical rotation component. In practice, each cable anchorage end 1 on the higher end of the vertical rotation component should be equipped with one cable tensioning device as described in this technical solution. Specifically, the cable tensioning device mainly includes a cable force identification module 14, a mechanical transmission module, and a tensioning module. The cable force identification module 14 is mainly used to monitor and collect the tension of any strand 7 in the cable. It includes several force measuring elements, which are respectively installed on each strand 7 in the cable. The mechanical transmission module includes a three-stage rotation... The three-stage rotary hinge structure includes a first rotary hinge structure 9, a second rotary hinge structure 10, and a third rotary hinge structure 11 connected in sequence. The tensioning module includes a fixed cylinder 13, a working clamp, and a telescopic cylinder 12. The working clamp is set inside the fixed cylinder 13 and is used to clamp the end of the steel strand 7. The specific setting and clamping method can refer to the clamping part of the front clamp jack in the prior art. The telescopic cylinder 12 is fixedly connected to the end of the fixed cylinder 13 facing the cable anchoring end 1. The end of the first rotary hinge structure 9 is fixed to the surface of the vertical rotating component, and the end of the third rotary hinge structure 11 is fixed to the fixed cylinder 13.

[0043] Cable force identification module 14 design: This module intends to use the pressure sensor method, vibration frequency method or other effective methods to measure the cable force, and to lay out the corresponding measuring elements on the steel strand 7.

[0044] Mechanical transfer module design: This module consists of three rotary hinges. The first rotary hinge performs polar axis tracking to reach the precise directional position of the target coordinate θ component (one-dimensional approximate search); the second rotary hinge performs height tracking to reach the directional range Δh of the target coordinate h component and the directional range Δr of the target coordinate r component (two-dimensional fuzzy positioning), where Δh is the height range from the cable anchorage end 1 from which the mechanical transfer module can normally perform tensioning work, and Δr is the reasonable length range of the line connecting the two coordinate points along the polar axis. The setting logic relationship between Δh and Δr is: after r is precisely determined within the range of Δr, the value of h should not be outside its reasonable range Δh; the third rotary hinge performs radius tracking to reach the precise directional position of the target coordinate r component (three-dimensional precise locking).

[0045] The pressure plate 5 module design consists of four parts: fastening screws 6, pressure plate 5, under-plate spring 4, and under-plate clamping plate 3. The fastening screws fix the limiting pressure plate 5 to the cable anchoring end 1. The under-plate spring 4 and the under-plate clamping plate are set between the limiting pressure plate 5 and the cable anchoring end 1, ensuring that the tensioning module can tension the steel strand 7 individually while preventing the clamping plate from disengaging and the cable system from failing.

[0046] The tensioning module design consists of three parts: a fixed cylinder body 13, a working clamping plate, and a telescopic cylinder body 12. The working clamping plate is built into the fixed cylinder body 13. When the module is working, the fixed cylinder body 13 can clamp the steel strand 7 through the clamping plate, and then the telescopic cylinder extends to push the pressure plate 5 module to apply tension to the target steel strand 7.

[0047] Furthermore, a steel strand 7 shearing structure is sleeved on the outer side of the cable anchoring end 1. The steel strand 7 shearing structure includes a fixing ring 15, which is fixed to the outer side of the cable anchoring end 1. At least two lifting columns 16 are provided on the surface of the fixing ring 15. A lifting plate 19 is provided on the lifting column 16 and slidably connected thereto. The end of the lifting column 16 is provided with an end protrusion 20 to limit the movement of the lifting plate 19. The lifting plate 19 is provided with several through holes that match the steel strands 7 in the cable. A return spring 17 is provided on the lifting column 16. The return spring 17 is located between the fixing ring 15 and the lifting plate 19. Between them, fixed seats 22 are symmetrically arranged on the lifting plate 19, and telescopic rods 21 are arranged on the fixed seats 22. The output end of the telescopic rods 21 is set towards the middle of the lifting plate 19, and a cutter 23 is arranged on the output end of the telescopic rods 21. It is easy to understand that when the telescopic rods 21 move to the center of the lifting plate 19, that is, when the two cutters 23 are combined, they can cover the entire surface of the lifting plate 19. Under normal conditions, the lifting plate 19 is flush with the ends of several steel strands 7 located outside the cable anchoring end 1. The flush end arrangement will not affect or cause errors in the positioning of the steel strands 7 by the mechanical transfer module.

[0048] Under the action of the mechanical transfer module, the fixed cylinder 13 and the telescopic cylinder 12 will move and fit onto the end of the slack steel strand 7. At this time, during the process of moving and fitting, the telescopic cylinder 12 will contact the lifting plate 19 and squeeze the return spring 17. When the compression spring is compressed to the limit position, it can play a supporting role. Thus, it is possible for the end of the telescopic cylinder 12 to abut against the lifting plate 19 for tensioning. At the same time, after the mechanical transfer module is reset, under the action of the return spring 17, the lifting plate 19 will return to the position flush with the end of the steel strand 7. Then, the telescopic rod 21 is activated, which can drive the cutter 23 to move towards the middle of the middle lifting plate 19, thereby cutting the end of the steel strand 7 that has become longer after tensioning, so that the end of the tensioned steel strand 7 is flush with the end of the other steel strands 7. That is, the protruding end of the steel strand 7 will not interfere with or obstruct the positioning of the other slack steel strands 7 by the subsequent mechanical rotation module.

[0049] Furthermore, the fixed ring 15 is also provided with several limiting posts 18. The limiting posts 18 are evenly distributed along the circumference of the limiting ring. The setting of the limiting posts 18 can limit and support the position of the lifting plate 19, that is, it will not cause excessive compression of the return spring 17, that is, the return spring 17 will not be damaged due to excessive compression.

[0050] like Figure 10 As shown, this technical solution also discloses a tensioning method for a long linear structure large-angle vertical rotation cable tensioning device, including the following steps:

[0051] ① The intelligent control system determines the position where the mechanical transfer module last stopped, initializes itself, and confirms the current position coordinates;

[0052] ②Trace the position coordinates of the steel strand 7 with the minimum tension, and confirm the relationship between θ, h, and r and the position coordinates of the mechanical transmission module;

[0053] ③ The mechanical transmission module starts the first rotary hinge structure 9 to perform polar axis tracking and reach the precise directional position of the target coordinate θ component;

[0054] ④ The mechanical transmission module starts the second rotary hinge structure 10 to perform height tracking and reach the target coordinate h component direction interval Δh and r component direction interval Δr;

[0055] ⑤ The mechanical transmission module activates the third rotary hinge structure 11 to perform radius tracking and reach the precise directional position of the target coordinate r component;

[0056] ⑥ After the mechanical transfer module transfers the tensioning module to the locking position, the video system verifies and confirms it;

[0057] ⑦ After confirming that everything is correct, the tensioning module begins to work;

[0058] ⑧ After tensioning is completed, the mechanical transfer module is reset;

[0059] ⑨ Restart the cable force identification module 14 to monitor the force on each steel strand 7 of the cable in real time, and determine whether to restart the intelligent tension control system program according to the difference in cable force values.

[0060] The above steps are as follows:

[0061] First, the cable force is measured using a pressure sensor, vibration frequency method, or other effective methods. When the difference Δij between the cable forces of any two steel strands 7 is less than the specified target limit K, the intelligent control system remains silent; when the difference Δij between the cable forces of any two steel strands 7 is greater than the specified target limit K, the intelligent control system starts working. ① The intelligent control system determines the position where the mechanical transfer module last stopped, initializes, and confirms the current position coordinates. ② It tracks the position coordinates of the steel strand 7 with the minimum tension and confirms the θ, h, and r values ​​between these coordinates and the position coordinates of the mechanical transfer module. Here, θ is the angle between the line connecting the two coordinate points and the horizontal line (θ is the polar axis direction), h is the distance from the cable anchorage end 1 at which the mechanical transfer module can perform normal tensioning work, and r is the length of the line connecting the two coordinate points along the polar axis direction (r is the polar axis radius). ③ The mechanical transfer module activates the first rotating hinge structure 9 to perform polar axis tracking and reach the precise directional position of the target coordinate θ component (one-dimensional approximate search). ④ The mechanical transfer module activates the second rotary hinge structure 10 to perform height tracking, reaching the direction interval Δh of the h component and the direction interval Δr of the r component of the target coordinates (two-dimensional fuzzy positioning). Δh is the height interval of the cable anchorage end 1 from which the mechanical transfer module can normally perform tensioning work, and Δr is the reasonable length interval of the line connecting the two coordinate points along the polar axis. The logical relationship between Δh and Δr is: after r is precisely determined within the range of Δr, the value of h should not be outside its reasonable interval Δh. ⑤ The mechanical transfer module activates the third rotary hinge structure 11 to perform radius tracking, reaching the precise direction position of the r component of the target coordinates (three-dimensional precise locking). ⑥ After the mechanical transfer module transfers the tensioning module to the locked position, the video system verifies and confirms it. ⑦ After verification, the tensioning module begins to work. The fixed cylinder 13 can clamp the steel strand 7 using its built-in clamps, and then the retractable hydraulic cylinder extends to push the pressure plate 5 module to apply tension to the target steel strand 7. ⑧ After tensioning is completed, the mechanical transfer module resets to its initial position, and the intelligent tensioning program ends. ⑨ Restart the cable force identification module 14 to monitor the force on each strand 7 of the cable in real time, and determine whether to restart the intelligent tensioning control system program based on the difference in cable force values.

[0062] like Figure 11 and Figure 12As shown, this technical solution also discloses the application of a cable tensioning device for large-angle vertical rotation of long linear structures, which is mainly used for the large-angle vertical rotation installation of ultra-high towers, ultra-high piers and arch ribs 8.

[0063] It should be noted that this technical solution should also include the control system and several electronic control components in the prior art. The mechanical transmission module should also include other connecting parts, drive parts and electronic control components, etc., to control the movement of the first rotary hinge axis, the second rotary hinge axis and the third rotary hinge axis, so as to realize the spatial positioning of the relaxed steel strand 7. The method of using three axes to achieve precise positioning is the prior art, such as the structure of the robot in the prior art. Therefore, it has not been described in detail in this technical solution.

[0064] It is important to emphasize that the application scenarios of this technical solution are mainly for the installation of ultra-high towers, ultra-high piers, and arch ribs. Applying the devices and methods in this technical solution to the construction industry, or to the vertical rotation installation of long linear structures at large angles, is unprecedented and undeveloped in this industry. The installation method is as follows: Figure 9 , Figure 11 and Figure 12 As shown in the installation diagram, the lower end of the arch rib 8 is located on the ground, and the cable at the lower end is connected to components such as jacks. There is not enough space or a good way to tension the single slack steel strand 7 at the lower end. Therefore, the traditional method is to use a crane to send workers to the cable anchoring end 1 at the higher end of the arch rib 8 to tension the slack steel strand 7. However, this method is ultimately limited by the height of the arch rib 8, and the risk of manual high-altitude operations is relatively high. Therefore, the structure of this technical solution and the tensioning method using this structure were developed during the actual installation process. Thus, this technical solution is designed and developed to address the difficulties in the existing installation process.

[0065] Finally, this technical solution proposes an intelligent control system at the anchorage end of the cable that can tension any single steel strand. It can replenish tension on a single slack steel strand from the anchorage end (where the position is high and construction personnel cannot reach it; and where the tensioning end cannot tension a single steel strand in the cable due to the setting of the tensioning components). This effectively solves the problem that when the structure is vertically rotated to a high position, the cable force of the vertically rotated cable is significantly reduced, and some steel strands in the cable experience relatively little or no force.

[0066] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
