Description

Technical Field

[0001] This disclosure relates to the field of bridge technology, and in particular to a reaction frame assembly. Background Technology

[0002] A suspension bridge is a bridge in which cables serve as the main load-bearing structure. The cables are typically suspended from the main cable saddles at the top of the main towers and anchored to both banks. The dynamic and static loads on the bridge deck are transferred to the main cable saddles via the cables, and then from the main cable saddles to the main towers.

[0003] In related technologies, when installing the main cable saddle at the top of the main cable tower, hoisting equipment is first used to hoist the main cable saddle to the top of the main cable tower. Since it is difficult to place the main cable saddle to the predetermined position at the top of the main cable tower in one go after it has been hoisted to the top, the position of the main cable saddle often needs to be fine-tuned.

[0004] When fine-tuning the main cable saddle, a reaction frame is typically installed on the side wall of the main tower. This reaction frame is fixed to the side wall of the main tower using anchoring or embedding methods. Then, a jacking cylinder is installed between the reaction frame and the main cable saddle to push the saddle to the predetermined position. However, since the reaction frame serves as a support component for the jacking cylinder, it is usually removed after the main cable saddle has been pushed in, in order to avoid affecting the bridge's aesthetics, thus resulting in waste. Summary of the Invention

[0005] This disclosure provides a reaction frame assembly that can be reused multiple times, avoiding waste caused by cutting off the reaction frame after use. The technical solution is as follows:

[0006] This disclosure provides a reaction frame assembly comprising: a reaction frame, a tie rod, a locking element, and a pre-embedded sleeve for embedding in and passing through a cable tower; the reaction frame includes: a mounting plate, a locking seat, and a pushing seat, the locking seat being located on the surface of the mounting plate, the pushing seat being located on the side of the mounting plate, the locking seat having a first through hole passing through the locking seat, the mounting plate having second through holes corresponding one-to-one with the first through hole, the first through hole and the corresponding second through hole being coaxial; the tie rod is inserted into the first through hole, the second through hole, and the inner hole of the pre-embedded sleeve, one end of the tie rod protruding from the side of the locking seat away from the pre-embedded sleeve, the other end of the tie rod protruding from the end of the pre-embedded sleeve away from the reaction frame, both ends of the tie rod being provided with the locking element, the locking element being detachably connected to the tie rod.

[0007] In one implementation of this disclosure, the locking component includes a locking washer and a locking nut. Both the locking washer and the locking nut are sleeved on the outside of the pull rod. The two ends of the pull rod are provided with external threads. The locking nut is threadedly connected to the pull rod through the external threads. The locking washer is located between the locking nut and the pre-embedded sleeve. The end face of the locking washer near the locking nut is a first end face. At least a portion of the first end face is a concave spherical surface. The center of the spherical surface of the first end face is located on the central axis of the locking washer. The end face of the locking nut near the locking washer is a second end face. At least a portion of the second end face is a convex spherical surface. The center of the spherical surface of the second end face is located on the central axis of the locking nut. The locking nut abuts against the locking washer, and the spherical surface of the first end face fits against the spherical surface of the second end face.

[0008] In another implementation of the present disclosure, the outer peripheral wall of the locking nut is provided with a radially extending recessed hole.

[0009] In another implementation of this disclosure, the pull rod includes a first sub-rod, a second sub-rod, and an elastic element. One end of the first sub-rod has a countersunk hole with an internal thread. One end of the second sub-rod has an external thread. One end of the elastic element is connected to one end of the second sub-rod, and the other end of the elastic element is connected to the bottom surface of the countersunk hole. One end of the second sub-rod is inserted into the countersunk hole and is threadedly connected to the countersunk hole. When the first sub-rod and the second sub-rod are threadedly connected, the elastic element is in a compressed state, and the compressed length of the elastic element is greater than the length of the second sub-rod inserted into the countersunk hole.

[0010] In another implementation of this disclosure, the reaction frame assembly includes two reaction frames, each of which has a first connecting hole on its mounting plate. The reaction frame assembly also includes a connecting plate, a connecting bolt, and a connecting nut. The connecting plate has a second connecting hole that corresponds one-to-one with the first connecting hole. The connecting plate is press-fitted onto the mounting plates of the two reaction frames. The connecting bolt is inserted into the corresponding first and second connecting holes. The connecting nut is threadedly connected to the connecting bolt.

[0011] In another implementation of this disclosure, the locking seat includes a locking plate and a plurality of support plates. The sides of the plurality of support plates are all located on the same side of the locking plate and are perpendicularly connected to the locking plate. The sides of the plurality of support plates away from the locking plate are perpendicularly connected to the surface of the mounting plate. The first through hole is located on the locking plate.

[0012] In another implementation of the present disclosure, the push base includes a base plate and a push plate. The side of the push plate is located on the surface of the base plate and is perpendicularly connected to the base plate. The side of the base plate is connected to the side of the mounting plate, and the base plate is perpendicularly connected to the mounting plate. The push plate and the mounting plate are located on opposite sides of the base plate.

[0013] In another implementation of this disclosure, the push base further includes an arc-shaped plate and two support plates. The two support plates are distributed in parallel, and one side of each support plate is connected to the surface of the arc-shaped plate. The sides of each support plate away from the arc-shaped plate are connected to the base plate. The arc-shaped plate and the push plate are located on the same side of the base plate, and the arc-shaped plate is located between the push plate and the mounting plate.

[0014] In another implementation of the present disclosure, the reaction frame assembly further includes a pre-embedded frame for embedding in the cable tower, the pre-embedded frame being located on the surface of the mounting plate, and the pre-embedded frame and the locking seat being located on opposite sides of the mounting plate.

[0015] In another implementation of the present disclosure, the embedded frame includes an embedded plate and a plurality of embedded hooks, one end of each of the plurality of embedded hooks being located on the surface of the embedded plate.

[0016] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0017] The reaction frame assembly provided in this embodiment has an embedded sleeve embedded inside the cable tower, and the sleeve penetrates the entire cable tower. When the reaction frame needs to be installed on the cable tower, the tie rod passes sequentially through the first through hole of the locking seat, the second through hole of the mounting plate, and the inner hole of the embedded sleeve, with both ends of the tie rod protruding from the locking seat and the embedded sleeve, respectively. By installing locking components at both ends of the tie rod, the reaction frame can be fixed to the side wall of the cable tower. Since the locking components and the tie rod are detachably connected, the locking components can be removed from both ends of the tie rod after the main cable saddle is pushed to the predetermined position, allowing the reaction frame to be removed from the cable tower. This eliminates the need to cut and discard the reaction frame, allowing it to be reused multiple times and avoiding waste caused by cutting it after use. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0047] Figure 1 This is a front view of a reaction frame assembly provided in an embodiment of this disclosure. Figure 2 This is a top view of a reaction frame assembly provided in an embodiment of this disclosure. Figure 1 , 2 As shown, the reaction frame assembly includes: a reaction frame, a tie rod 20, a locking element, and a pre-embedded sleeve 40 for embedding in and through the cable tower 50.

[0048] Figure 3 This is a front view of a reaction frame provided in an embodiment of this disclosure. (As shown...) Figure 3 As shown, the reaction frame includes: a mounting plate 11, a locking seat 12, and a pushing seat 13. The locking seat 12 is located on the plate surface of the mounting plate 11, and the pushing seat 13 is located on the side of the mounting plate 11. The locking seat 12 has a first through hole 120 that passes through the locking seat 12. The mounting plate 11 has a second through hole 110 that corresponds one-to-one with the first through hole 120. The first through hole 120 and the corresponding second through hole 110 are coaxial.

[0049] like Figure 1 , 2 As shown, the pull rod 20 is inserted into the first through hole 120, the second through hole 110 and the inner hole of the pre-embedded sleeve 40. One end of the pull rod 20 protrudes from the side of the locking seat 12 away from the pre-embedded sleeve 40, and the other end of the pull rod 20 protrudes from the end of the pre-embedded sleeve 40 away from the reaction frame. Both ends of the pull rod 20 are provided with locking parts, and the locking parts are detachably connected to the pull rod 20.

[0050] The reaction frame assembly provided in this embodiment has an embedded sleeve embedded within the cable tower 50, and the sleeve penetrates the cable tower 50. When the reaction frame needs to be installed on the cable tower 50, the tie rod 20 passes sequentially through the first through hole 120 of the locking seat 12, the second through hole 110 of the mounting plate 11, and the inner hole of the embedded sleeve 40, while both ends of the tie rod 20 protrude from the locking seat 12 and the embedded sleeve 40, respectively. By providing locking components at both ends of the tie rod 20, the reaction frame can be fixed to the side wall of the cable tower 50. Since the locking components and the tie rod 20 are detachably connected, the locking components can be removed from both ends of the tie rod 20 after the main cable saddle is pushed to the predetermined position, allowing the reaction frame to be removed from the cable tower 50. This eliminates the need to cut off the reaction frame, preventing its scrapping and allowing for multiple reuses, thus avoiding waste caused by cutting off the reaction frame after use.

[0051] Optionally, such as Figure 1 As shown, the locking components include a locking washer 31 and a locking nut 32, both of which are fitted over the pull rod 20.

[0052] Figure 4 This is a schematic diagram of the structure of a pull rod 20 provided in an embodiment of this disclosure. Figure 4 As shown, the two ends of the pull rod 20 are provided with external threads.

[0053] like Figure 1As shown, the locking nut 32 is threadedly connected to the pull rod 20 via an external thread, and the locking washer 31 is located between the locking nut 32 and the pre-embedded sleeve 40.

[0054] In the above implementation, locking nuts 32 are provided at both ends of the pull rod 20, so that the pull rod 20 can be fixed at both ends of the pre-embedded sleeve 40. Since the pull rod 20 and the locking nuts 32 are threadedly connected, the locking nuts 32 and the pull rod 20 can be detachably connected by rotating the locking nuts 32.

[0055] Figure 5 This is a schematic diagram of the structure of a locking washer 31 provided in an embodiment of this disclosure. Figure 5 As shown, the end face of the locking washer 31 near the locking nut 32 is the first end face 311. At least a portion of the first end face 311 is a concave spherical surface, and the center of the spherical surface of the first end face 311 is located on the central axis of the locking washer 31.

[0056] Figure 6 This is a schematic diagram of the structure of a locking nut 32 provided in an embodiment of this disclosure. Figure 6 As shown, the end face of the locking nut 32 near the locking washer 31 is the second end face 321. At least a portion of the second end face 321 is a convex spherical surface. The center of the spherical surface of the second end face 321 is located on the central axis of the locking nut 32. The locking nut 32 abuts against the locking washer 31.

[0057] In this embodiment of the disclosure, such as Figure 1 As shown, the spherical surface of the first end face 311 is in contact with the spherical surface of the second end face 321.

[0058] By setting the surfaces where the locking washer 31 and the locking nut 32 fit together to be spherical, the locking nut 32 can be screwed onto the pull rod 20 to ensure that the locking nut 32 and the locking washer 31 remain coaxial, preventing misalignment of the locking nut 32 and the locking washer 31 and preventing the locking nut 32 from loosening.

[0059] Figure 7 This is a top view of a locking nut 32 provided in an embodiment of this disclosure. (See attached image.) Figure 7 As shown, the outer peripheral wall of the locking nut 32 is provided with a radially extending recess 322.

[0060] A recessed hole 322 is provided on the outer peripheral wall of the locking nut 32, and the recessed hole 322 is used to insert a shaft-like part. In this way, when the locking nut 32 cannot be turned, a shaft-like part can be inserted into the recessed hole 322, and by turning the part, the locking nut 32 can be rotated to continue to rotate, so that the locking nut 32 can be more reliably fixed on the pull rod 20.

[0061] For example, such as Figure 7As shown, a plurality of recessed holes 322 are provided on the outer peripheral wall of the locking nut 32, and the plurality of recessed holes 322 are arranged circumferentially at intervals.

[0062] The diameter of the different recesses 322 can be different. This allows for the insertion of shaft parts of different diameters.

[0063] As an example, the wall of the recess 322 can be provided with internal threads. The end of the shaft part can be provided with external threads, so that the shaft part can be threadedly connected in the recess 322 to prevent the shaft part from easily falling out of the recess 322 when it is turned.

[0064] Optionally, such as Figure 1 As shown, the locking seat 12 includes a locking plate 121 and a plurality of support plates 122. The sides of the plurality of support plates 122 are all located on the same side of the locking plate 121, and the support plates 122 are perpendicularly connected to the locking plate 121. The sides of the plurality of support plates 122 away from the locking plate 121 are perpendicularly connected to the surface of the mounting plate 11. The first through hole 120 is located on the locking plate 121.

[0065] In the above implementation, the locking seat 12 adopts a frame structure with a hollow design. This allows the position of the end of the pull rod 20 to be observed through the hollow design of the locking seat 12 after the pull rod 20 is inserted into the locking seat 12 through the first through hole 120 of the locking plate 121, thus facilitating accurate control of the pull rod 20's insertion into the second through hole 110 of the mounting plate 11.

[0066] For example, the locking seat 12 and the support plate 122 can be fixedly connected by welding, which is convenient for processing and manufacturing.

[0067] The frame structure formed by the locking plate 121 and multiple support plates 122 can reduce the overall weight of the reaction frame assembly, making it easier to lift the reaction frame assembly to the top of the tower 50.

[0068] Optionally, such as Figure 1 As shown, the push base 13 includes a base plate 131 and a push plate 132. The side of the push plate 132 is located on the plate surface of the base plate 131 and is perpendicularly connected to the base plate 131. The side of the base plate 131 is connected to the side of the mounting plate 11 and is perpendicularly connected to the mounting plate 11. The push plate 132 and the mounting plate 11 are located on opposite sides of the base plate 131.

[0069] In this embodiment, the mounting plate 11 is a plate in the reaction frame used to fit against the side wall of the tower 50, and the side of the mounting base plate 131 of the mounting plate 11 is flush with the top of the tower 50. In this way, after the reaction frame is installed on the tower 50, the push plate 132 of the push seat 13 can protrude from the top of the tower 50 so as to abut against the push cylinder, so that the push cylinder can push the main cable saddle.

[0070] Figure 8 This is a side view of a reaction frame provided in an embodiment of this disclosure. Figure 8 The middle left side is Figure 3 MM-directed view, Figure 8 The middle right side is Figure 3 NN cross-section view.

[0071] like Figure 8 As shown, the push base 13 also includes an arc plate 133 and two support plates 134. The two support plates 134 are distributed in parallel, and one side of the two support plates 134 is connected to the surface of the arc plate 133. The side of the two support plates 134 away from the arc plate 133 is connected to the base plate 131. The arc plate 133 and the push plate 132 are located on the same side of the base plate 131.

[0072] like Figure 4 As shown, the arc-shaped plate 133 is located between the push plate 132 and the mounting plate 11.

[0073] In this embodiment of the present disclosure, the arc plate 133 is used to support the cylinder of the push cylinder. Therefore, the radius corresponding to the arc surface of the arc plate 133 can be the same as the radius corresponding to the outer wall surface of the cylinder, so that the outer wall surface of the cylinder can fit with the arc surface of the arc plate 133 and prevent the push cylinder from easily loosening.

[0074] For example, the arc plate 133 and the support plate 134 can be fixedly connected by welding, which is convenient for processing and manufacturing.

[0075] The frame structure formed by the arc plate 133 and multiple support plates 134 can reduce the overall weight of the reaction frame assembly, making it easier to lift the reaction frame assembly to the top of the tower 50.

[0076] Optionally, such as Figure 1 As shown, the reaction frame assembly also includes a pre-embedded frame 70 for embedding in the cable tower 50. The pre-embedded frame 70 is located on the plate surface of the mounting plate 11, and the pre-embedded frame 70 and the locking seat 12 are located on opposite sides of the mounting plate 11.

[0077] An embedded frame 70 is also provided on the surface of the mounting plate 11. The embedded frame 70 is used to be embedded in the side wall of the tower 50. In this way, the weight of the reaction frame can be borne not only by the tie rod 20, but also by the embedded frame 70, which can reduce the shear force of the tie rod 20 and improve the reliability of the reaction frame assembly.

[0078] Figure 9 This is a structural schematic diagram of a pre-embedded bracket 70 provided in an embodiment of this disclosure. (See diagram below.) Figure 9 As shown, the embedded frame 70 includes an embedded plate 71 and a plurality of embedded hooks 72, one end of each of the plurality of embedded hooks 72 being located on the surface of the embedded plate 71.

[0079] The embedded plate 71 is used to connect with the mounting plate 11. For example, both the embedded plate 71 and the mounting plate 11 are provided with screw holes. After the reaction frame is installed on the side wall of the cable tower 50, the embedded plate 71 and the mounting plate 11 are fixed together with bolts, so that the embedded hook can also bear the weight of the reaction frame.

[0080] For example, such as Figure 9 As shown, one end of the pre-embedded hook 72 is bent, which makes the pre-embedded hook 72 more securely hooked into the tower 50 and prevents the pre-embedded hook 72 from falling off.

[0081] Optionally, a pad can be provided between the embedded plate 71 and the mounting plate 11 to prevent the reaction frame from abutting too tightly against the embedded plate 71 and causing wear, thereby improving reliability.

[0082] Figure 10 This is a structural schematic diagram of a pre-embedded sleeve 40 provided in an embodiment of this disclosure. (See attached diagram.) Figure 10 As shown, the embedded sleeve 40 includes a cylinder and two embedded flanges, which are located at both ends of the cylinder and are coaxially connected to the cylinder.

[0083] In this embodiment of the disclosure, the diameter of the cylinder is greater than or equal to the diameter of the pull rod 20, so that the pull rod 20 can pass through.

[0084] The embedded cylinder is installed inside the pylon 50, and the embedded flange is also installed inside the pylon 50, with the end face of the embedded flange flush with the side wall of the pylon 50. This way, when the mounting plate 11 of the reaction frame is installed on the side wall, the mounting plate 11 can simultaneously fit against both the side wall of the pylon 50 and the end face of the embedded flange, making the mounting plate 11 more reliably abut against the side wall of the pylon 50.

[0085] Optionally, a gasket can be placed between the embedded flange and the mounting plate 11 to prevent the reaction frame from coming into excessive contact with the embedded sleeve 40 and causing wear, thereby improving reliability.

[0086] Figure 11 This is a schematic diagram of another reaction frame provided in an embodiment of this disclosure. Figure 12 This is a side view of another reaction frame provided in an embodiment of this disclosure. Figure 12 It means Figure 11 AA section view. Figure 13 This is a top view of another reaction frame provided in an embodiment of this disclosure.

[0087] like Figure 12 , 13 As shown, the reaction frame assembly includes two reaction frames, and each reaction frame's mounting plate 11 is provided with a first connection hole 111.

[0088] like Figure 12 ,13 As shown, the reaction frame assembly also includes a connecting plate 61, a connecting bolt 62, and a connecting nut 63. The connecting plate 61 has a second connecting hole 610 that corresponds one-to-one with the first connecting hole 111. The connecting plate 61 is press-fitted onto the mounting plates 11 of the two reaction frames. The connecting bolt 62 is inserted into the corresponding first connecting hole 111 and second connecting hole 610. The connecting nut 63 is threadedly connected to the connecting bolt 62.

[0089] In the above implementation, the two reaction frames are detachably connected together via connecting plate 61. Compared to Figure 1 The reaction frame shown is divided into two smaller reaction frames, left and right. Because the smaller reaction frames are lighter and easier to transport, they can be assembled on-site. This also shortens the manufacturing cycle and reduces manufacturing costs.

[0090] Figure 14 This is a schematic diagram of another pull rod 20 provided in an embodiment of this disclosure. (See attached diagram.) Figure 14 As shown, the pull rod 20 includes a first sub-rod 21, a second sub-rod 22, and an elastic element 23. One end of the first sub-rod 21 has a countersunk hole 210 with an internal thread. One end of the second sub-rod 22 has an external thread. One end of the elastic element 23 is connected to one end of the second sub-rod 22, and the other end of the elastic element 23 is connected to the bottom surface of the countersunk hole 210. One end of the second sub-rod 22 is inserted into the countersunk hole 210, and the second sub-rod 22 is threadedly connected to the countersunk hole 210.

[0091] In this embodiment, when the first sub-rod 21 and the second sub-rod 22 are threadedly connected, the elastic element 23 is in a compressed state, and the compressed length of the elastic element 23 is greater than the length of the second sub-rod 22 inserted into the countersunk hole 210.

[0092] During use, the first sub-rod 21 and the second sub-rod 22 are threaded together to form a single unit. When the reaction frame needs to be disassembled, the second sub-rod 22 is screwed out of the countersunk hole 210 of the first sub-rod 21 by turning it. At this time, the elastic force of the elastic element 23 is released, applying a reciprocating elastic force to the first sub-rod 21 and the second sub-rod 22. Since the compressed length of the elastic element 23 is greater than the length of the second sub-rod 22 inserted into the countersunk hole 210, after the first sub-rod 21 and the second sub-rod 22 move within the pre-embedded sleeve 40, the locking nuts at the ends of the first sub-rod 21 and the second sub-rod 22 can be separated from the side wall of the tower 50. Because there is no friction between the end face of the locking nut and the side wall of the tower 50, it is easier to remove the locking nut from the tie rod 20, which helps to increase the difficulty of disassembling the reaction frame.

[0093] For example, the elastic element 23 can be a spring, with one end of the spring connected to one end of the second sub-rod 22 and the other end of the spring connected to the bottom surface of the countersunk hole 210. When the first sub-rod 21 and the second sub-rod 22 are threadedly connected, the spring is in a compressed state, and the compressed length of the spring is greater than the length of the second sub-rod 22 inserted into the countersunk hole 210.

[0094] For example, at least one of the first and second sub-stems is circumferentially movably connected to the spring. For instance, the end face of the second sub-stem has a spherical groove, the arc corresponding to the axial section of the spherical groove being a major arc, and one end of the spring has a spherical structure located within the spherical groove. This ensures that when the first sub-stem is screwed into the inner hole of the second sub-stem, the first sub-stem does not exert torque on the spring, thus improving the spring's stability.

[0095] The usage process of the reaction frame assembly provided in this embodiment is as follows:

[0096] First, embed the pre-embedded sleeve 40 inside the tower 50, making the pre-embedded flanges at both ends of the pre-embedded sleeve 40 flush with the side wall of the tower 50.

[0097] Then, the reaction frame is hoisted to a suitable height, so that the tie rod 20 passes through the pre-embedded sleeve 40 and the locking seat 12 of the reaction frame, and the threads at both ends of the tie rod 20 protrude from the locking seat 12 of the reaction frame and the side wall of the tower 50.

[0098] Next, lock washers 31 and lock nuts 32 are installed on the threads at both ends of the pull rod 20. The flat surface of the lock washer 31 faces the locking seat 12, and the spherical surface of the lock washer 31 and the spherical surface of the lock nut 32 are installed facing each other. The lock nut 32 on the side of the locking seat 12 is rotated to press the lock washer 31 against the locking seat 12. The lock nut 32 away from the locking seat 12 is rotated to press the lock washer 31 against the embedded flange.

[0099] Then, install the tension nut 80 at the end of the tie rod 20 away from the locking seat 12, and use the through-type hydraulic jack and the tension nut 80 to tension the tie rod 20 step by step to the design tension requirement.

[0100] Next, using a shaft-like component, such as a pry bar, insert it into a recess 322 of the locking nut 32 and manually rotate the pry bar to cause the locking nut 32 and the locking washer 31 to press tightly against the embedded flange.

[0101] Finally, the jacking cylinder is placed on the arc plate 133 of the reaction frame for jacking. After the main cable saddle is jacked to the predetermined position, the reaction frame, tie rod 20, locking washer 31, locking nut 32, tension nut 80, and pad are removed and reused for jacking construction of other main cable saddles.
