Description

Technical Field

[0001] This invention relates to the field of bridge construction technology, specifically to an integrated anti-top and anti-roll mechanism and device for cable-stayed formwork. Background Technology

[0002] The cable-stayed formwork adds a cable-stayed system at the front end of the formwork. By applying upward pretension to the front end of the formwork through the stay cables, part of the cast-in-place load is transferred to the main tower of the cable-stayed bridge. This improves the stress condition of the formwork's load-bearing structure, significantly increasing its load-bearing capacity and the construction length of the main beam segments. Therefore, it is widely used in the construction of long-span concrete cable-stayed bridges.

[0003] The cable-stayed formwork construction involves two working conditions: movement and anchoring. In the movement condition, the cable-stayed formwork needs to be moved using a roll-back mechanism that contacts the bottom of the beam. When the formwork reaches its anchoring position, the roll-back mechanism needs to be disassembled and a top-mounting mechanism installed to adjust the formwork's position and balance the anchoring force. The existing solution has the following problems:

[0004] 1. The jacking mechanism and the anti-rolling mechanism are two independent sets of mechanisms, occupying a large amount of operating space under the beam. At the same time, when the cable-stayed formwork is used for working condition switching, it is necessary to manually install and disassemble the two sets of mechanisms repeatedly, which is labor-intensive and complicated.

[0005] 2. During the movement of the cable-stayed basket, due to its own deformation, asynchronous movement of the hanging legs on both sides, and uneven load distribution, the anti-rolling mechanism is subjected to a large jacking force. The existing anti-rolling mechanism is composed of rollers and bearings directly connected, which can easily cause the anti-rolling mechanism to jam with the bottom of the beam, resulting in damage to the concrete structure.

[0006] 3. When assembling the cable-stayed formwork, the anti-top and anti-roll mechanisms occupy a lot of operating space, which is not convenient for the assembly and construction of the formwork.

[0007] 4. The lifting and anti-rolling mechanisms are difficult to maintain. If they are damaged, they need to be disassembled as a whole and cannot be replaced in parts, which takes a long time. Summary of the Invention

[0008] In view of the deficiencies in the existing technology, the purpose of this invention is to provide an integrated anti-top and anti-roll mechanism and device for cable-stayed formwork, which can solve the problems in the above-mentioned background technology, such as the need to repeatedly disassemble and assemble the anti-top and anti-roll mechanisms during the construction process of cable-stayed formwork, complicated conversion operations, two independent mechanisms occupying a large space, the anti-roll mechanism being prone to jamming with the bottom of the beam, and difficulty in maintenance.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is: an integrated anti-top and anti-roll mechanism for a cable-stayed basket, comprising a fixed base, wherein a groove is provided on the top surface of the fixed base, and a flipping base is rotatably connected in the groove; an anti-top head is fixedly connected to the top of the flipping base, and an anti-rolling head is rotatably connected to the bottom of the flipping base.

The limiting plate is disposed on the outside of the rotating seat, and a limiting groove is formed on the limiting plate at the position corresponding to the rotating seat. The limiting groove is adapted to the shape of the rotating seat.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this invention, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0039] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the invention.

[0040] See Figure 1 and Figure 2 As shown, this embodiment of the invention provides an integrated anti-top and anti-roll mechanism for a cable-stayed basket, including a fixed base 101. A groove is formed on the top surface of the fixed base 101, and a flip base 102 is rotatably connected within the groove. An anti-top head 104 is fixedly connected to the top of the flip base 102, and an anti-roll head 105 is rotatably connected to the bottom of the flip base 102. Integrating the anti-top head and the anti-roll head into the same mechanism improves the practicality of the invention while reducing the space occupied under the beam.

[0041] Preferably, the interior of the flipping seat 102 is provided with a vertically arranged slide groove 107, and a horizontally arranged slider 106 is slidably connected in the slide groove 107. Both ends of the slider 106 are fixedly connected to a connecting shaft 103. The connecting shaft 103 is rotatably connected to the fixed seat 101, and the side of the slider 106 facing the anti-roll head 105 is fixedly connected to one end of the first spring 108. The other end of the first spring 108 is fixedly connected to the bottom surface of the slide groove 107, and the first spring 108 is always in a compressed state.

[0042] It should be noted that when the present invention is used for reverse jacking, the reverse jacking head is upward. At this time, the reverse jacking head is fixed when subjected to force, which improves the reverse jacking stability. When the reverse rolling head is upward, as the reverse rolling head is subjected to force, the reverse rolling head has a certain buffer movement space, which can effectively avoid the jamming state caused by excessive force on the reverse rolling head, and effectively improve the working stability and safety of the present invention.

[0043] Preferably, the fixed base 101 is fixedly connected to the top surface of the connecting base 110; the end of the connecting shaft 103 extends out of the fixed base 101 and is fixedly connected to a rectangular block 109, and a snap-fit ​​base 111 is slidably connected to the outer wall of the fixed base 101; the top of the snap-fit ​​base 111 has a groove with the same shape as the rectangular block 109; when the rectangular block enters the groove, it can be fixed by the snap-fit ​​base, thereby fixing the flip base; the bottom surface of the snap-fit ​​base 111 is fixedly connected to the top end of the second spring 112, the bottom end of the second spring 112 is fixedly connected to the connecting base 110, and the second spring 112 is always in a compressed state. When it is necessary to flip the flip base to switch the reverse top and reverse roll functions, the snap-fit ​​base is pulled down until the snap-fit ​​base is completely separated from the rectangular block, which is simple and convenient to operate.

[0044] See Figure 3 As shown, this embodiment of the invention also provides an integrated anti-top and anti-roll device for a cable-stayed basket, including a steel beam 2. A flipping mechanism 3 is provided on the side of the steel beam 2. One end of the flipping mechanism 3 is rotatably connected to the steel beam 2, and the other end of the flipping mechanism 3 is connected to the integrated anti-top and anti-roll mechanism 1 as described above, which is used to realize the conversion between the vertical state and the horizontal state of the integrated anti-top and anti-roll mechanism 1.

[0045] See Figure 4 As shown, the flipping mechanism 3 includes a rotating seat 31, which is rotatably connected to the side of the steel beam 2 via a rotating shaft 32, and the top of the rotating seat 31 is fixedly connected to the anti-rolling integrated mechanism 1.

[0046] Preferably, a first hydraulic rod 35 is vertically arranged between the rotating seat 31 and the anti-rolling integrated mechanism 1; the bottom end of the first hydraulic rod 35 is fixedly connected to the top of the rotating seat 31, and the top end of the first hydraulic rod 35 is fixedly connected to the bottom of the connecting seat 110 of the anti-rolling integrated mechanism 1.

[0047] It should be noted that the first hydraulic rod can adjust the counter-jacking force of the counter-jacking structure, and at the same time adjust the height of the counter-rolling mechanism to adapt to the construction of variable cross-section main beams and improve the practicality of the present invention.

[0048] Preferably, a limiting key 34 integrally formed with the rotating shaft 32 is fixedly connected to the end side wall extending outside the rotating seat 31. A square groove 33 penetrating the rotating seat 31 is provided at the bottom of the rotating seat 31, and the shapes of the limiting key 34 and the square groove 33 are compatible. When the anti-top and anti-rolling mechanisms are damaged and need maintenance, the rotating seat is rotated in the opposite direction of the baffle. After rotation, the positions of the limiting key and the square groove correspond. At this time, the rotating seat can be directly slid off along the rotating shaft. The operation is simple and convenient, greatly simplifying the workload of maintenance workers.

[0049] See Figures 5-7As shown, it also includes a limit locking mechanism 4, which includes a limit plate 41 and a drive unit. The limit plate 41 is disposed on the outside of the rotating seat 31, and a limit groove 42 is formed on the limit plate 41 corresponding to the position of the rotating seat 31. The limit groove 42 is adapted to the shape of the rotating seat 31. The drive unit is connected to the limit plate 41 and is used to drive the limit plate 41 to move closer to or away from the rotating seat 31, thereby realizing the locking and unlocking of the rotating seat 31.

[0050] Preferably, a baffle 43 is fixedly connected to the bottom of one end of the steel beam 2 facing the limiting plate 41, and a receiving groove 44 is provided on the limiting plate 41 at the position corresponding to the baffle 43. The baffle can support the anti-top and anti-roll mechanisms when they are stored, and the receiving groove can facilitate the limiting plate to fit onto the steel beam and avoid interference.

[0051] Preferably, the drive unit includes a connecting rod 47 and a connecting plate 46; the connecting rod 47 passes through and slides on the steel beam 2, and one end of the connecting rod 47 is fixedly connected to the limiting plate 41, and the other end of the connecting rod 47 is fixedly connected to the connecting plate 46; the connecting plate 46 is fixedly connected to one end of a plurality of parallel-arranged second hydraulic rods 45, and the other end of the second hydraulic rods 45 is fixedly connected to the steel beam 2. In this embodiment, two connecting rods 47 are provided, which are respectively connected to both ends of the limiting plate 41.

[0052] When the anti-top and anti-roll integrated device is working, the second hydraulic rod extends and the rotating seat enters the limiting groove, thereby locking and fixing the rotating seat to ensure the normal operation of the anti-top and anti-roll mechanism. When the anti-top and anti-roll mechanism is not working, the second hydraulic rod shortens, causing the limiting plate to lose its limiting effect on the rotating seat, thus allowing the anti-top and anti-roll integrated mechanism to be stored away, reducing space occupation and facilitating the assembly and construction of the hanging basket.
