Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a fast alignment tool for a stay cable tensioning jack. Background Art

[0002] As the mainstream bridge type of long-span bridges, cable-stayed bridges have been widely used in modern bridge construction. The tensioning of the cables is a crucial part of the bridge construction process. The quality of the tensioning construction not only directly affects the structural safety and stability of the bridge during the completion stage, but also affects the efficiency and economy of the subsequent maintenance work, such as the adjustment of the cable force of the cable-stayed bridge. If the tensioning construction quality does not meet the standards, it may lead to problems such as uneven cable force distribution and bridge deformation, increase the time cost of subsequent maintenance and cause economic losses.

[0003] In traditional cable-stayed cable tensioning construction, large-tonnage jacks are usually used to complete the tensioning operation. However, due to their large size and heavy weight, these jacks need to rely on forklifts or other lifting machinery for lifting during the installation process of the cable anchor cup, which increases the complexity of the construction and equipment dependence. In addition, due to the certain inclination angle between the cable and the horizontal plane of the box girder, it is difficult to align the jack during installation, and it is difficult to quickly and accurately install it to the cable anchor cup end. These problems not only prolong the construction time, but also require more on-site operators to cooperate in the operation, which seriously reduces the construction efficiency. At the same time, the extension of the construction period and the increase in labor costs directly lead to an increase in the overall construction cost, affecting the economic benefits of the project. Therefore, how to improve the technology and equipment of cable-stayed cable tensioning construction to improve construction efficiency, reduce costs and reduce dependence on large machinery has become a key issue that needs to be solved in the construction of cable-stayed bridges. Summary of the invention

It takes a long time and requires a large number of on-site workers, which seriously reduces the construction efficiency.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The embodiment of the present application provides a quick alignment tool for a cable-stayed cable tensioning jack, which can solve the technical problems in the prior art of using large-tonnage jacks to complete tensioning operations, increasing the complexity of construction. At the same time, the cable forms a certain angle with the horizontal plane of the box girder, making it difficult to align the jack, and it is difficult to quickly and accurately install it to the anchor cup end of the cable. It takes a long time and requires a large number of on-site workers, which seriously reduces the construction efficiency.

[0027] The rapid alignment tooling in the present application includes a base component and a rotating component. The base component carries the rotating component, and the base component can flexibly adjust its own inclination direction and inclination angle during the tensioning process of the inclined cable, so as to facilitate the rapid adjustment of the rotating component to align with the inclined cable to be tensioned. The base component faces the inclined cable to be tensioned, and after the angle is aligned, it can rotate itself to mechanically connect the inclined cable to be tensioned to perform the tensioning work. The overall operation is simple and the alignment efficiency is high, which can greatly improve the tensioning efficiency.

[0028] Specifically, Figure 1 A schematic diagram of a fast alignment tooling structure of a cable-stayed tensioning jack provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the base assembly includes an adjusting base ring 1 and at least two connecting mechanisms 2 which are radially symmetrically arranged on the adjusting base ring 1, and are used to connect external traction ropes respectively, and use the traction torque difference and traction direction deviation between the traction ropes to adjust the inclination angle and inclination direction of the adjusting base ring 1. The adjusting base ring 1 is a metal ring structure, one end of the connecting mechanism 2 is fixedly connected to the adjusting base ring 1 to form a whole, and the other end is reserved for connecting positions of external traction ropes. The number of connecting mechanisms 2 is even, and every two groups of connecting mechanisms 2 are radially symmetrically arranged along the adjusting base ring 1. In a possible embodiment, the connecting mechanism 2 is two groups to connect two traction ropes. When the traction directions and traction torques of the two traction ropes differ, the inclination angle of the adjusting base ring 1 will also change accordingly, until the cross section of the adjusting base ring 1 is perpendicular to the axis of the inclined cable to be tensioned, and the rotating assembly is located on the side of the adjusting base ring 1 facing the inclined cable to be tensioned. Therefore, when the cross section of the adjusting base ring 1 is perpendicular to the axis of the inclined cable to be tensioned, it means that the axis of the rotating assembly coincides with the axis of the inclined cable to be tensioned, and the alignment can be completed at this time.

[0029] Furthermore, the rotating assembly includes a hollow jack 3 that can rotate circumferentially relative to the adjusting bottom ring 1, and a reaction nut 4 located in the inner ring of the hollow jack 3 and can rotate circumferentially relative to the hollow jack 3 for connecting the inclined cable to be tensioned.

[0030] The cross section of the hollow jack 3 is also annular, and is a commonly used component in the field of inclined cables. No further elaboration is given here. The cross-sectional area of ​​the hollow jack 3 is not larger than the cross-sectional area of ​​the adjusting bottom ring 1, and is preferably consistent with the cross-sectional area of ​​the adjusting bottom ring 1. The fixed end of the hollow jack 3 is attached to the side of the adjusting bottom ring 1, and the telescopic end faces the inclined cable to be tensioned. The reaction nut 4 is fitted on the inner ring of the hollow jack 3, and can maintain two states of relative stillness and relative rotation with the hollow jack 3. The reaction nut 4 also has an annular structure at one end facing the inclined cable to be tensioned, and the cross section of the other end is It is consistent with the cross-section of the inner ring of the adjusting bottom ring 1 so as to fit into the inner ring of the adjusting bottom ring 1. During the alignment process, the adjusting bottom ring 1 always remains stationary after the angle is adjusted. The reaction nut 4 is screwed into the anchor cup end of the inclined cable to be tensioned, the adjusting bottom ring 1 is removed, and the reaction nut 4 is continued to be rotated. After the movable end of the hollow jack 3 is in contact with the support foot preset in advance by the outside world, the hollow jack 3 starts to tension. The above-mentioned may also be other components such as fixed feet, which can fix the current position of the hollow jack 3 and play a reaction role to ensure the normal tensioning action of the hollow jack 3.

[0031] It should be noted that an anchor cup is provided at the end of the cable to be tensioned, and an external thread is provided on the outer circumferential wall of the anchor cup. The pitch, tooth type and rotation direction of the internal thread on the inner wall of the reaction nut 4 are configured to completely correspond to the external thread on the anchor cup, so that the precise matching and tight engagement between the two can be achieved through the circumferential rotation of the reaction nut 4. Through this threaded connection method, the anchor cup can be firmly fixed inside the reaction nut 4, ensuring that the end of the cable to be tensioned will not loosen or move during the tensioning process, while being able to withstand large tensioning forces and vibration loads. In addition, this design is also easy to install and disassemble, improves construction efficiency and operational convenience, and makes the tensioning process of the cable safer, more stable and controllable. At the stage of connecting the anchor cup, the hollow jack 3 rotates with the reaction nut 4.

[0032] Furthermore, Figure 2 An exploded diagram of a fast alignment tooling for a cable-stayed tensioning jack provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the connecting mechanism 2 includes a traction ear 201 arranged on the outer circumferential wall of the adjusting bottom ring 1. Combined with the above description, there are two connecting mechanisms 2, and the traction ears 201 in the two connecting mechanisms 2 are radially symmetrically arranged. A connecting through hole is opened on the connecting ear, and two external traction ropes pass through the two traction ears 201 respectively. During the alignment work, the adjusting bottom ring 1 is first placed vertically, and the two connecting ears are in upper and lower positions in space. The traction rope connected to the upper connecting ear applies vertical force, and the traction rope connected to the lower connecting ear applies horizontal force and the traction torque of the traction rope is relatively large. At this time, the bottom of the adjusting bottom ring 1 begins to tilt toward the inclined cable to be tensioned, and continues to apply tension toward the traction rope connected to the lower connecting ear until the adjusting bottom ring 1 tilts until its cross section is perpendicular to the inclined cable to be tensioned.

[0033] For further information, see Figure 2 A rotation guide mechanism 5 for supporting the fixed end of the hollow jack 3 is provided on the side of the adjusting bottom ring 1 facing the hollow jack 3. In the initial stage of assembly of the overall alignment tooling, the reaction nut 4 is first sleeved on the inner ring of the hollow jack 3, and then the positions of the two and the adjusting bottom ring 1 are adjusted. At this stage, the reaction nut 4 and the hollow jack 3 are relatively stationary, but at the same time they rotate relative to the adjusting bottom ring 1. The guiding mechanism supports the fixed end of the hollow jack 3, which can reduce the rotational friction resistance between the hollow jack 3 and the adjusting bottom ring 1 and improve the overall work efficiency.

[0034] Furthermore, the rotation guide mechanism 5 includes a plurality of fixed bases 501 evenly distributed along the circumference of the adjusting bottom ring 1, and a universal ball 502 is arranged inside the fixed base 501 to realize a flexible rotation guide function. One end of the fixed base 501 is fixedly connected to the side of the adjusting bottom ring 1 facing the hollow jack 3 to form an integrated structure to ensure the stability and reliability of the overall structure; the other end extends horizontally and protrudes toward the hollow jack 3 to form a support and guide function. A recessed portion is provided at the horizontal protruding end of the fixed base 501, and the recessed portion is used to accommodate the universal ball 502, and its inner diameter is slightly larger than the outer diameter of the universal ball 502 to ensure that the universal ball 502 can freely perform universal rotation in the recessed portion, thereby realizing flexible adjustment in multiple directions. After assembly, the universal ball 502 partially protrudes from the outside of the fixed base 501 and directly contacts the fixed end of the hollow jack 3. The rotation of the universal ball 502 reduces friction resistance, ensuring that the adjustment base ring 1 can smoothly and flexibly adjust the position and angle when subjected to force, thereby improving the working efficiency and accuracy of the overall mechanism. The number of fixed bases 501 and universal ball 502 is preferably 6 to 8 groups, and each group is equidistantly arranged.

[0035] Furthermore, in order to improve the connection stability and movement flexibility between the hollow jack 3 and the reaction nut 4, a threaded connection method is adopted between the two to achieve the dual functions of firm connection and flexible movement. Specifically, a first internal thread is processed on the inner ring of the hollow jack 3, and the first internal thread is evenly distributed along the inner wall to form a continuous spiral structure; at the same time, a first external thread matching the first internal thread is processed on the outer periphery of the reaction nut 4, and the pitch, tooth type and rotation direction of the first external thread are completely corresponding to the first internal thread to ensure that the two can be tightly meshed. Through the design of threaded connection, the hollow jack 3 and the reaction nut 4 can maintain a relative static state when needed to achieve stable force transmission and fixed support; and can achieve flexible movement adjustment through relative rotation under external force, so as to meet the use requirements under different working conditions. This threaded connection method not only enhances the overall stability of the structure, but also significantly improves the accuracy and efficiency of motion control, making the cooperation between the hollow jack 3 and the reaction nut 4 more reliable and easy to operate.

[0036] Furthermore, the outer diameter of the reaction nut 4 is designed to be smaller than the inner diameter of the adjusting bottom ring 1 to ensure that the reaction nut 4 can be smoothly embedded in the inner ring of the adjusting bottom ring 1. Specifically, one end of the reaction nut 4 facing the adjusting bottom ring 1 protrudes from the outside of the hollow jack 3 and is embedded in the inner ring of the adjusting bottom ring 1, thereby achieving a tight combination of the two. In combination with the above description, one end of the reaction nut 4 is fixed to the inner ring of the hollow jack 3 through a threaded connection to ensure the connection stability and force transmission efficiency between the two; and the other end of the reaction nut 4 protrudes from the outside of the hollow jack 3 and is embedded in the inner ring of the adjusting bottom ring 1 to further enhance the integrity and stability of the structure.

[0037] In a possible implementation, the length of the portion of the reaction nut 4 protruding from the outside of the hollow jack 3 is equal to the thickness of the reaction nut 4. This design enables the end of the reaction nut 4 to be located on the same plane as its cross section, which not only simplifies the structural design, but also improves the convenience and accuracy of assembly. At the same time, this equal-length design helps to evenly distribute the force and avoid local stress concentration, thereby improving the reliability and durability of the overall structure. Through this optimized design, the connection between the reaction nut 4 and the adjusting bottom ring 1 and the hollow jack 3 is tighter, which can effectively cope with the high loads and complex stress conditions generated during the tensioning of the inclined cable, ensuring the safety and efficiency of the construction process.

[0038] Furthermore, Figure 3 A side view of a fast alignment tooling for a cable-stayed tensioning jack provided in an embodiment of the present application, as shown in FIG. Figure 2 As shown, a toggle mechanism 6 is provided on one end face of the reaction nut 4 facing the adjusting bottom ring 1, and the toggle mechanism 6 is used to assist the rotation operation of the reaction nut 4, so as to realize the connection and tensioning operation of the anchor cup. In combination with the above description, the inner ring of the reaction nut 4 is provided with an internal thread, and the pitch, tooth type and rotation direction of the internal thread are completely matched with the external thread of the anchor cup part of the inclined cable to be tensioned, so as to ensure that the anchor cup can be firmly screwed into the reaction nut 4, thereby realizing a stable connection between the two. The toggle mechanism 6 is arranged on the end face of one side of the reaction nut 4 embedded in the adjusting bottom ring 1 close to the beam end, and its design purpose is to facilitate the operator to apply torque through the toggle mechanism 6 during the construction process, so that the reaction nut 4 can be easily rotated, thereby completing the connection work of the anchor cup. The specific form of the toggle mechanism 6 can be a plurality of evenly distributed toggle grooves, toggle holes or toggle protrusions, so as to facilitate the use of tools for operation. Through the setting of the toggle mechanism 6, not only the rotation operation of the reaction nut 4 is simplified, but also the construction efficiency is improved, and the labor cost and time cost are reduced.

[0039] The design of the toggle mechanism 6 also takes into account the complexity of the construction environment and the convenience of operation. For example, when there is a certain angle between the inclined cable and the horizontal plane of the box beam, the toggle mechanism 6 can help the operator to more accurately control the rotation angle and speed of the reaction nut 4, ensuring that the threaded connection between the anchor cup and the reaction nut 4 is tight and uniform, avoiding loose connection or damage caused by misalignment or improper operation. This design further improves the reliability and safety of the inclined cable tensioning construction, and also helps to reduce the difficulty and cost of later maintenance.

[0040] In a possible embodiment, the toggle mechanism 6 includes a rotating connecting rod 601 disposed transversely on a side of the adjusting bottom ring 1 away from the reaction nut 4, and a fixing bolt 602 penetrating the rotating connecting rod 601 and connected to the reaction nut 4. Specifically, the rotating connecting rod 601 is arranged transversely on the outside of the adjusting bottom ring 1, and its axis is perpendicular to the axis of the adjusting bottom ring 1, so that the operator can apply torque toward the reaction nut 4 through the rotating connecting rod 601. The fixing bolt 602 penetrates the center or a specific position of the rotating connecting rod 601, one end of which is fixedly connected to the rotating connecting rod 601, and the other end extends to the reaction nut 4 and is connected thereto, so as to transmit the rotational motion of the rotating connecting rod 601 to the reaction nut 4, realize the rotation control of the reaction nut 4, and the operator can easily apply torque through the rotating connecting rod 601 to drive the reaction nut 4 to rotate, thereby completing the connection or disassembly of the anchor cup. The length and shape of the rotating connecting rod 601 can be designed according to actual construction requirements to provide sufficient leverage and reduce the difficulty of operation. At the same time, the connection method of the fixing bolt 602 ensures the efficiency and stability of force transmission between the rotating connecting rod 601 and the reaction nut 4, avoiding construction errors or safety hazards caused by loose connections.

[0041] The alignment tooling of the present invention has a simple structure and can be quickly installed and disassembled. The angle of the bottom ring 1 can be quickly adjusted through an external traction rope to drive the rotating assembly to quickly align the inclined cable to be tensioned, which can significantly improve the construction efficiency. At the same time, the alignment tooling in the present application is light in weight and small in size, and has lower requirements for lifting equipment, which can save more operating space. In the absence of lifting equipment, a simple bracket can be built and lifted with a pulley or hand winch, which can be completed by only 2 to 3 operators, saving labor costs and being more economical.
