Description

Technical Field

[0001] This invention relates to the field of bridge high pier construction technology, and in particular to a limiting device during the climbing process of a bridge high pier climbing frame. Background Technology

[0002] High piers are important supporting structures for highway, railway, and municipal bridges. The quality of high pier construction directly affects the safety and durability of the bridge during its use. At present, the construction of high piers for bridges generally adopts two methods: flip-form and hydraulic climbing form. Compared with the flip-form method, the hydraulic climbing form has the advantages of simple structure, easy installation, convenient operation, high safety, fast construction speed, and low labor input. It is the wall-attached climbing form technology widely used at home and abroad.

[0003] The main components of a hydraulic climbing formwork include a bottom platform, a middle platform, and a frame installed on the middle platform. A hydraulic lifting mechanism is installed between the bottom platform and the middle platform. The climbing formwork is lifted by this hydraulic lifting mechanism. During the climbing process, a limit mechanism needs to be installed on the middle platform to ensure the stability of the climbing formwork during the climbing process and to avoid safety and quality accidents.

[0004] Traditional high-pier climbing scaffolding typically uses triangular supports for horizontal limiting. However, traditional horizontal limiting devices are all point supports, resulting in poor overall force distribution. Furthermore, traditional horizontal limiting devices are generally only installed on the two long sides of the central platform. This setup can only limit the climbing scaffolding in the direction perpendicular to the long sides, leading to poor overall limiting effect. Summary of the Invention

[0005] To address the above technical problems, this invention provides a limiting device for the climbing process of a bridge high pier climbing frame, which realizes the limiting function of the climbing frame in both the X and Y directions in the horizontal direction, strengthens the limiting function of the climbing frame, and ensures construction safety and construction quality.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a limiting device for the climbing process of a bridge pier climbing frame, comprising multiple Bailey panels, which are rotatably connected to the central platform of the climbing frame. The so-called rotatable connection with the central platform means that they can rotate around the central platform to be lowered when the climbing frame is climbing and retracted when not climbing. Each Bailey panel is perpendicular to the facade of the bridge pier.

[0007] By adopting the above technical solution and using Bailey panels as limiting devices, finished products can be directly purchased, saving processing time and costs. The Bailey panel storage technology allows for vertical placement during the climbing frame as it ascends, providing better horizontal limiting. After the climbing frame is completed, the Bailey panels can be flipped and stored, ensuring ample working space. In addition, in extreme weather conditions such as strong winds, the Bailey panels can be rotated to a vertical position to resist the corresponding overturning moment, thereby reducing safety hazards during the construction of high bridge piers. The rotational connection between the Bailey panels and the central platform can be achieved through hinge shafts or by controlling the flipping mechanism.

[0008] Preferably, at least one roller is provided on the side of the Bailey panel closest to the bridge pier.

[0009] By adopting the above technical solution, rolling contact between the Bailey bridge sheet and the bridge pier is achieved. Rolling friction has less friction than sliding friction, which protects the surface quality of the cast bridge pier. As a preferred option, universal rollers are selected here so that no matter what angle or position the Bailey bridge sheet is in, the roller will ensure that its outer diameter keeps in vertical contact with the pier under its own weight.

[0010] Preferably, the Bailey plate is rotatably connected to the central platform via a flipping mechanism, and the Bailey plate is fixedly connected to the flipping mechanism. The angle between the Bailey plate and the central platform changes as the flipping mechanism moves. Bailey plates are provided on all four sides of the central platform.

[0011] By adopting the above technical solution and using a flipping mechanism to control the flipping and storage of Bailey panels, the system becomes more stable and reliable. Due to the retractability of the Bailey panels, it achieves the beneficial effect of installation on the two short sides of the central platform, and realizes the limiting function of the climbing frame in the horizontal X and Y directions, thereby improving the limiting function of the limiting device.

[0012] Preferably, the flipping mechanism is a linkage mechanism, including a fixed rod, a driving rod, a connecting rod, and a rhomboid structure hinged to the connecting rod; the fixed rod is fixedly connected to the central platform, the driving rod and the connecting rod are respectively hinged to the two ends of the fixed rod, the rhomboid structure is hinged to the connecting rod, and the end of the driving rod away from the fixed rod is hinged to the rhomboid structure.

[0013] By adopting the above technical solution, the beneficial effect of rotating the Bailey plate can be achieved by rotating the active rod. Moreover, the flipping mechanism of the linkage mechanism is simple and safe and reliable. The angle between the Bailey plate and the central platform can be accurately controlled through the flipping mechanism, thereby limiting the position of the Bailey plate, reducing safety hazards, and improving the limiting effect.

[0014] Preferably, the rhomboid structure includes rod one, rod two, and rod three; rod one and rod two are opposite sides, one end of rod two is hinged to the end of the connecting rod away from the fixed rod, one end of rod one is hinged to the rod body of the connecting rod, the section from the hinge point of rod one and the connecting rod to the end of the connecting rod away from the fixed rod is part of the rhomboid structure, which is equivalent to the opposite side of rod three, and the two ends of rod three are respectively hinged to the other end of rod one and the other end of rod two, and the active rod is hinged on the hinge axis of rod one and rod three.

[0015] By adopting the above technical solution, the rotation of rod one and rod two is controlled by the active rod, and the extreme positions of rod one and rod two can reach a position parallel to the central platform. Compared with other methods, the rotation range is larger. In addition, the use of a rhombus structure to achieve rotation allows the total length of the Bailey panel after it is retracted to the fixed rod to be adjusted by changing the side length of the rhombus. This adapts to the different space characteristics of different central platforms that can accommodate Bailey panels, and achieves better processing performance.

[0016] Preferably, one side of the long side of the Bailey plate is fixedly connected to one of the rods, either rod one or rod two.

[0017] By adopting the above technical solution, the Bailey panels are fixed on the flipping mechanism, and the flipping mechanism controls the flipping of the Bailey panels. Because the Bailey panels themselves are of high quality, fixing them to the flipping mechanism makes them safer and effectively avoids construction safety hazards.

[0018] Preferably, a flipping mechanism is provided on both sides of the long side of the Bailey plate.

[0019] By adopting the above technical solution, a more stable fixed Bailey panel was achieved, effectively avoiding potential construction safety hazards.

[0020] Preferably, the end of the active rod away from the fixed rod is provided with a locking device, and a fixing device adapted to the locking device is provided on the middle platform.

[0021] By adopting the above technical solution, a better locking effect is achieved on the flipping mechanism and Bailey plate when they are in the storage state, thus improving safety performance.

[0022] Preferably, the clip is a hook, and both sides of the long side of the Bailey plate are provided with a flipping mechanism, and the opening directions of the hooks on the two flipping mechanisms are opposite.

[0023] By adopting the above technical solution, because the Bailey panels are relatively heavy, they may detach from the hooks due to their own weight. The openings of the hooks face upwards and downwards, which reduces the possibility of the hooks falling off the fasteners on their own.

[0024] Preferably, the fastener includes a fixed shaft, a spring, and a movable shaft. The fixed shaft is fixed on the central platform, and the movable shaft is connected to the fixed shaft via the spring, allowing the movable shaft to be movably connected to the central platform.

[0025] This technical solution has a simple structure and is safe and reliable. When the hook opening direction is opposite, it is difficult to detach the hook from the fastener by operating it. However, with this structure, the hook can be separated from the fastener by manually pulling the moving shaft.

[0026] In summary, the present invention has the following beneficial technical effects:

[0027] 1. Using Bailey panels as limiting devices allows for the direct purchase of finished products, saving processing time and costs. The Bailey panels are designed to be retractable, and when the climbing frame is being raised, they are set vertically for better horizontal limiting. After the climbing frame is completed, the Bailey panels are flipped and stored, ensuring ample working space. In addition, in the event of strong winds or other extreme weather, the Bailey panels can be rotated to a vertical position to resist the corresponding overturning moment, thereby reducing safety hazards during the construction of high bridge piers.

[0028] 2. Because the Bailey panels themselves are of high quality, they can be more securely installed on the flipping mechanism, effectively avoiding potential construction safety hazards. In addition, the retractable nature of the Bailey panels allows for installation on the two short sides of the central platform, achieving the effect of limiting the horizontal movement of the climbing frame in both the X and Y directions, thus improving the limiting function of the limiting device.

[0029] 3. The flipping mechanism adopts a linkage mechanism. The flipping mechanism is fixedly connected to the central platform and the Bailey panels. The flipping of the Bailey panels is achieved through the linkage structure. First, it ensures the safe and reliable installation of the Bailey panels. Second, it achieves a larger rotation range of the Bailey panels. It also enables accurate control of the angle between the Bailey panels and the central platform.

[0030] 4. Because the Bailey panel may detach from the hook under its own weight, the technical solution of having one hook opening facing upwards and the other downwards reduces the possibility of the hook detaching from the fixing component. In addition, when the structure with hook openings facing opposite directions is used, it is difficult to detach the hook from the fixing component by operation. However, with this technical solution, the hook can be separated from the fixing component by manually pulling the moving shaft. The structure is simple, safe and reliable.

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Example 1

[0043] This embodiment discloses a limiting device during the climbing process of a bridge pier 3 climbing frame, referring to... Figure 1 and Figure 2 The limiting device includes six Bailey panels 1. Each Bailey panel 1 has five universal rollers on the side close to the bridge pier 3 to achieve rolling contact between the Bailey panel 1 and the bridge pier 3, reducing friction. Two Bailey panels 1 are rotatably connected to the two long sides of the central platform 2, and one Bailey panel 1 is rotatably connected to the two short sides of the central platform 2. The so-called rotatable connection with the central platform 2 means that it can rotate around the central platform 2. The Bailey panels 1 are rotatably connected to the central platform 2 through the flipping mechanism 4. The Bailey panels 1 are fixed to the flipping mechanism 4. The angle between the Bailey panels 1 and the central platform 2 changes with the movement of the flipping mechanism 4. Each Bailey panel 1 is perpendicular to the facade of the bridge pier 3.

[0044] Using Bailey panel 1 as the limiting device allows for direct procurement of finished products, saving processing time and costs. The Bailey panel 1 is also designed for easy storage; during scaffolding ascent, it is vertically positioned. Figure 1 This provides better horizontal limiting. After the climbing scaffold has finished climbing, Bailey plate 1 is flipped over for storage, as per [reference]. Figure 2This ensures ample working space. In addition, in the event of extreme weather such as strong winds, the Bailey plate 1 can be rotated to a vertical position to resist the corresponding overturning moment, thereby reducing safety hazards during the construction of the bridge pier 3.

[0045] In addition, due to the retractability of the Bailey plate 1, it is possible to install it on the two short sides of the middle platform 2, which has the beneficial effect of limiting the climbing frame in the horizontal X and Y directions, and improving the limiting function of the limiting device.

[0046] Reference Figure 3 The flipping mechanism 4 is a linkage mechanism, including a fixed rod 41, a driving rod 42, a connecting rod 43, and a rhomboid structure 44 hinged to the connecting rod 43. The fixed rod 41 is fixedly connected to the central platform 2, which makes the connection more stable and reliable. The driving rod 42 and the connecting rod 43 are respectively hinged to the two ends of the fixed rod 41. The rhomboid structure 44 is hinged to the connecting rod 43. The end of the driving rod 42 away from the fixed rod 41 is hinged to the rhomboid structure 44, which realizes a larger rotation range of the Bailey plate 1. The rhomboid structure 44 includes rod one 441, rod two 442, and rod three 443. Rod one 441 and rod two 442 are opposite sides. One end of rod two 442 is hinged to the end of the connecting rod 43 away from the fixed rod 41. One side of the long side of the Bailey piece 1 is fixedly connected to the second rod 442. One end of the first rod 441 is hinged to the body of the connecting rod 43. The section from the hinge point of the first rod 441 and the connecting rod 43 to the end of the connecting rod 43 away from the fixed rod 41 is part of the rhomboid structure 44, which is equivalent to the opposite side of the third rod 443. The two ends of the third rod 443 are respectively hinged to the other end of the first rod 441 and the other end of the second rod 442. The active rod 42 is hinged on the hinge axis of the first rod 441 and the third rod 443. This allows the total length of the Bailey piece 1 after it is folded up to the fixed rod 41 to be adjusted by changing the side length of the rhombus. This adapts to the different space characteristics of the different middle platforms 2 that can accommodate the Bailey piece 1, and has better processing performance.

[0047] Reference Figure 3 Both sides of the long side of the Bailey panel 1 are equipped with a flipping mechanism 4, which makes the fixing of the Bailey panel 1 more stable and reliable, and effectively avoids construction safety hazards.

[0048] Reference Figure 3 and Figure 4A locking element 45 is provided at the end of the active rod 42 away from the fixed rod 41. A fixing element 5 adapted to the locking element 45 is provided on the middle platform 2, which achieves a better locking effect on the flipping mechanism 4 and the Bailey piece 1 in the storage state, improving safety performance. The locking element 45 is a hook. Flipping mechanisms 4 are provided on both sides of the long side of the Bailey piece 1. The openings of the hooks on the two flipping mechanisms 4 are one facing upward and the other facing downward, which can effectively prevent the Bailey piece 1 from automatically detaching from the fixing element 5 under its own weight. The fixing element 5 includes a fixed shaft 51, a spring 52 and a moving shaft 53. The fixed shaft 51 is fixed on the middle platform 2. The moving shaft 53 is connected to the fixed shaft 51 through the spring 52 and is movably connected to the middle platform 2. When the structure with opposite hook openings is used, it is difficult to detach the hook from the fixing element 5 by operating it. However, with this structure, the hook can be separated from the fixing element 5 by manually pulling the moving shaft 53.

[0049] Example 2

[0050] The difference between this embodiment and embodiment 1 is that one side of the long side of the Bailey piece 1 is fixedly connected to the rod 441. Under this technical solution, the total length of the Bailey piece 1 and the fixed rod 41 in the stored state is less than the length of the technical solution in embodiment 1. It can be seen that this is also a way to adjust the total length of the Bailey piece 1 and the fixed rod 41 in the stored state.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
