Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge repair technology, and in particular to a bridge pier correction device. Background Technology
[0002] Due to their height and small cross-section, bridge piers have relatively low lateral stiffness. As the dynamic loads on the bridge accumulate over the years, the piers are prone to tilting. If the tilt is not corrected in time, the pier will continue to tilt, and the concrete at the base facing away from the tilt will gradually become the tension zone. Since the concrete has poor tensile strength, circumferential cracks will gradually appear on the concrete surface and continue to develop, eventually causing the pier structure to be completely damaged.
[0003] For example, Chinese patent "CN219490724U" discloses "A Bridge Pier Reset and Correction Device." This correction device, through the installation of a pier support plate, a first hydraulic drive mechanism, a pier side extension frame, a pier fixing arm, a second hydraulic rod, and a correction support plate, achieves the ability to be adjusted according to the size of the pier, making it applicable to most bridge piers for correction work. It has strong applicability, and the design of the pier support plate, pier side extension frame, and pier fixing arm allows the device to be expanded according to usage needs. However, the pier fixing arm in this device is a plate structure, and its contact with the pier is point-to-point, resulting in low installation stability. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a bridge pier column correction device, which solves the problem that the pier column fixing arm of the existing correction device is a plate structure, which makes point contact with the pier column, resulting in low installation stability.
[0005] According to the embodiments of this utility model, the following technical solution is adopted:
[0006] A bridge pier correction device, installed on the bridge pier, includes a support frame and correction jacks mounted on the support frame, and further includes:
[0007] An arc-shaped mounting frame is installed on the side of the bridge pier and connected to the load-bearing frame.
[0008] An arc-shaped fixing plate is installed on the side of the bridge pier and is positioned opposite to the arc-shaped mounting frame.
[0009] The system also includes an adjustment unit, which comprises an adjustment component and several steel cables. The adjustment component is located on the arc-shaped mounting frame, and the several steel cables are wound between the arc-shaped mounting frame and the arc-shaped fixing plate. The adjustment component is connected to the end of each steel cable and is used to adjust the tension of each steel cable to adjust the distance between the arc-shaped fixing plate and the arc-shaped mounting frame.
[0010] Preferably, the adjusting component includes an adjusting jack and a connecting plate. The adjusting jack is mounted on an arc-shaped mounting frame, the ends of each steel cable are connected to the connecting plate, and the telescopic end of the adjusting jack is connected to the connecting plate.
[0011] Preferably, the arc-shaped mounting frame is equipped with a limiting rod, and the limiting rod is slidably connected to a sliding plate. The telescopic end of the adjusting jack is connected to the sliding plate, and the sliding plate is fixedly connected to the connecting plate by screws.
[0012] Preferably, the connecting plate has an installation groove, which is slidably engaged with the limiting rod.
[0013] Preferably, the arc-shaped mounting frame has several limiting grooves corresponding to several steel cables, and each limiting groove has a guide wheel rotatably mounted therein, with each steel cable placed in its respective guide wheel.
[0014] Preferably, the arc-shaped fixing plate includes a first arc-shaped plate and two second arc-shaped plates, with the two second arc-shaped plates rotatably disposed at both ends of the first arc-shaped plate.
[0015] Preferably, it also includes two partitions, which are disposed opposite each other on both sides of the pier and located between the second arc-shaped plate and the arc-shaped mounting frame.
[0016] Preferably, the partition, the first arc plate and the second arc plate are each provided with a number of positioning grooves, and a number of steel cables are correspondingly arranged in the number of positioning grooves.
[0017] Preferably, the top of the arc-shaped mounting bracket is bent outward to form a limiting edge.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] In this solution, the curved mounting frame and the curved fixing plate are installed opposite each other on the side of the pier, and the curved surfaces of the curved mounting frame and the curved fixing plate are made to fit against the circumferential side of the pier. In addition, several steel cables are used to wrap between the curved mounting frame and the curved fixing plate. While adjusting the tension of the steel cables, the curved mounting frame and the curved fixing plate are made to fit tightly against the circumferential side of the pier. Compared with the point contact method, this solution improves the stability when correcting the pier.
[0020] In this solution, by installing the arc-shaped mounting frame and the arc-shaped fixing plate opposite each other on the side of the pier, and by adjusting the tension of the steel cable, until both the arc-shaped mounting frame and the arc-shaped fixing plate are in contact with the circumference of the pier, the correction device can be installed on piers of different diameters, making it applicable to more types of bridge pier correction work.

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0027] like Figure 1 and Figure 2 As shown, this utility model embodiment proposes a bridge pier column correction device, installed on the bridge pier 1, including a support frame 3 and a correction jack 4 disposed on the support frame 3, and further including:
[0028] The arc-shaped mounting frame 2 is located on the side of the pier 1 and is connected to the bearing frame 3;
[0029] An arc-shaped fixing plate 5 is installed on the side of the pier 1 and is positioned opposite to the arc-shaped mounting frame 2;
[0030] The system also includes an adjustment unit, which comprises an adjustment component and several steel cables 6. The adjustment component is located on the arc-shaped mounting frame 2. The several steel cables 6 are wound between the arc-shaped mounting frame 2 and the arc-shaped fixing plate 5. The adjustment component is connected to the end of each steel cable 6 and is used to adjust the tension of each steel cable 6 to adjust the distance between the arc-shaped fixing plate 5 and the arc-shaped mounting frame 2.
[0031] In this embodiment of the invention, the inner surfaces of both the arc-shaped mounting frame 2 and the arc-shaped fixing plate 5 are arc-shaped, increasing the contact area with the pier 1 and improving the stability of the pier 1 during correction compared to point contact. Simultaneously, with the assistance of the adjustment unit, one end of the steel cable 6 is fixedly anchored to one end of the arc-shaped mounting frame 2, and the other end of the steel cable 6 is wound around the circumferential surface of the pier 1 to the other end of the arc-shaped mounting frame 2 and connected to the adjustment component. This allows the arc-shaped mounting frame 2 and the arc-shaped fixing plate 5 to be wound with the steel cable 6. Through the action of the adjustment component, the steel cable 6 can be gradually tightened, allowing the arc-shaped mounting frame 2 and the arc-shaped fixing plate 5 to fit tightly against the surface of the pier 1 until the steel cable 6 is taut, completing the installation. Specifically, several steel cables 6 are laid one by one along the axial direction of the pier 1, and different numbers of steel cables 6 are selected to determine the contact area with the pier 1.
[0032] Secondly, in the early stage of assembly, since the positions of the arc-shaped mounting frame 2 and the arc-shaped fixing plate 5 can be installed at will, that is, the distance between the arc-shaped mounting frame 2 and the arc-shaped fixing plate 5 can be controlled at will, the arc-shaped mounting frame 2 and the arc-shaped fixing plate 5 can be placed on both sides of different bridge piers 1 respectively, and tightened by adjusting parts and steel cables 6, the correction device can be installed on bridge piers 1 of different diameters, so that it can be applied to more types of bridge pier correction work.
[0033] Because a large number of steel cables 6 are used, and to facilitate the synchronous adjustment of several steel cables 6, the adjusting components include adjusting jacks 7 and connecting plates 61. Adjusting jacks 7 are mounted on the arc-shaped mounting frame 2, and the ends of each steel cable 6 are connected to the connecting plate 61. The telescopic end of the adjusting jacks 7 is connected to the connecting plate 61. All the ends of the steel cables 6 are anchored to the connecting plate 61, so that when the connecting plate 61 moves, it can drive the ends of all the steel cables 6 to move as well. When the telescopic end of the adjusting jacks 7 retracts, it can synchronously drive the connecting plate 61 to slide within the arc-shaped mounting frame 2, thereby simultaneously tightening the steel cables 6.
[0034] At the same time, such as Figure 3 and Figure 4As shown, the arc-shaped mounting frame 2 is equipped with a limiting rod 21, and a sliding plate 71 is slidably mounted on the limiting rod 21. The telescopic end of the adjusting jack 7 is connected to the sliding plate 71, and the sliding plate 71 is fixedly connected to the connecting plate 61 by screws. The sliding path of the connecting plate 61 can be limited by the limiting rod 21 and the sliding plate 71, so that the connecting plate 61 can only move along the axis of the limiting rod 21, which also indirectly avoids the radial force on the telescopic end of the adjusting jack 7. Moreover, in order to facilitate the wrapping of several steel cables 6 around the pier 1, the connecting plate 61 is provided with an installation groove 62. The installation groove 62 is slidably engaged with the limiting rod 21. The connecting plate 61 is separated from the limiting rod 21 by the installation groove 62. After the steel cable 6 is wrapped around the pier 1, the installation groove 62 of the connecting plate 61 is engaged in the limiting rod 21, and the connecting plate 61 is fixedly installed on the sliding plate 71 by screws, thus completing the fixed installation.
[0035] Specifically, such as Figure 3 As shown, the arc-shaped mounting frame 2 has several limiting grooves corresponding to several steel cables 6. Each limiting groove contains a guide wheel 22, and each steel cable 6 is placed within its respective guide wheel 22. The guide wheels 22 effectively reduce direct friction between the steel cables 6 and the arc-shaped mounting frame 2 during tightening or loosening. By replacing sliding contact with rolling contact through the guide wheels 22, the wear on the steel cables 6 can be significantly reduced, extending their service life and thus improving the reliability and durability of the entire device.
[0036] Based on the above solutions, such as Figure 3 As shown, the arc-shaped fixing plate 5 includes a first arc-shaped plate 51 and two second arc-shaped plates 52. The two second arc-shaped plates 52 are respectively rotatably disposed at both ends of the first arc-shaped plate 51. The first arc-shaped plate 51 and the two second arc-shaped plates 52 are combined together by a rotatable connection. If the diameter of the pier 1 changes, the first arc-shaped plate 51 and the two second arc-shaped plates 52 can flexibly adjust the overall curvature, so that the arc-shaped fixing plate 5 can better fit the surface of the pier 1, thereby enhancing the versatility and applicability of the device.
[0037] Based on the above solutions, such as Figure 3 As shown, it also includes two partitions 8, which are arranged opposite each other on both sides of the pier 1 and located between the second arc-shaped plate 52 and the arc-shaped mounting frame 2. The partitions 8 can form additional support structures on both sides of the pier 1, further enhancing the overall stability of the device. At the same time, the partitions 8 can effectively disperse the tension transmitted by the steel cable 6, avoiding the force from being concentrated on the arc-shaped fixing plate 5 or the arc-shaped mounting frame 2, thereby reducing the risk of the device tilting or sliding due to uneven force. It can also prevent the steel cable 6 from being directly disconnected from the pier 1 and causing damage to the pier 1.
[0038] Specifically, such as Figure 2As shown, the partition plate 8, the first arc plate 51 and the second arc plate 52 are all provided with a number of positioning grooves 9, and a number of steel cables 6 are correspondingly placed in the number of positioning grooves 9. The positioning grooves 9 provide a clear path and fixed position for the steel cables 6, and prevent the steel cables 6 from shifting or twisting during tightening or loosening.
[0039] Specifically, the top of the arc-shaped mounting bracket 2 is bent outward to form a limiting edge 31. When the arc-shaped mounting bracket 2 is installed, the limiting edge 31 can position the arc-shaped mounting bracket 2 on the top of the pier 1 to ensure its installation stability and prevent it from moving downward, thus facilitating subsequent installation work.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
