Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary support device for bridge construction, belonging to the field of bridge construction technology. Background Technology
[0002] Bridge bearings are important components connecting the superstructure and substructure of a bridge. Located between the bridge and the piers, they reliably transfer the reaction forces and deformations (displacement and rotation) of the superstructure to the substructure, thus ensuring that the stress conditions of the overall structure conform to the theoretical calculation diagrams.
[0003] Bridge bearings can be classified into steel bearings, rubber bearings, and polytetrafluoroethylene (PTFE) bearings, based on the materials used. Over time, bridge bearings may experience damage or abnormal displacement, necessitating replacement. Due to the small distance between the bridge and piers where the bearings are installed, ordinary jacks are often insufficient for replacement. Thin jacks are typically used. However, in some cases, the distance between the bridge and piers is so small that even thin jacks cannot replace the bearings, making the replacement process quite complicated.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] This utility model addresses the shortcomings of the prior art by providing an auxiliary support device for bridge construction, which enables convenient replacement of bridge bearings, and the replacement process is not limited by the distance between the bridge and the pier.
[0006] To solve the above technical problems, the present invention adopts the following technical solution:
[0007] A bridge construction auxiliary support device includes a ring plate, which is sleeved and fixed to the periphery of the pier and is positioned near the top of the pier. Multiple fixed arms are fixedly connected to the periphery of the ring plate in a uniform distribution, and each fixed arm has a plug-in arm that is slidably connected to it.
[0008] The plug-in arm has a hollow structure. Inside the plug-in arm, two sliding rods are installed side by side. A connecting plate is installed at the bottom of the two sliding rods, and a lifting plate is installed at the top of the two sliding rods. A hydraulic cylinder is installed between the two side by side in a vertical direction. The tail of the hydraulic cylinder is connected to the plug-in arm through a fixed seat, and the head of the hydraulic cylinder is connected to the lifting plate.
[0009] Furthermore, the inner side of the ring plate is connected with multiple embedded bars, which are located inside the pier.
[0010] Furthermore, the inner end of the fixed arm is welded and fixed to the outer surface of the ring plate. The fixed arm is arranged in a horizontal direction and has a hollow structure. Multiple stiffening plates are provided inside the fixed arm.
[0011] Furthermore, the plug-in arm and the fixed arm are detachably connected.
[0012] Furthermore, the axis of the slide rod is set in the vertical direction, and linear bearings are respectively sleeved on the slide rod.
[0013] Furthermore, the linear bearing is fixed inside the plug arm, and the upper and lower end faces of the linear bearing are flush with the upper and lower end faces of the plug arm.
[0014] Furthermore, the sliding rod and the connecting plate, as well as the sliding rod and the lifting plate, are fixedly connected by connecting seats.
[0015] Furthermore, the thickness of the lifting plate is greater than the thickness of the connecting plate.
[0016] Furthermore, the mounting base is fixedly installed inside the plug arm.
[0017] Furthermore, both the fixed arm and the plug-in arm have a square cross-section along the longitudinal direction.
[0018] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:
[0019] When bridge bearings need to be replaced, an integrated structure consisting of a plug-in arm, hydraulic cylinder, lifting plate, and sliding rod is installed onto a fixed arm on the periphery of the pier. The hydraulic cylinder drives the lifting plate to rise, and two sliding rods on the left and right ensure the stability of the lifting plate's movement. After the bridge is raised by the lifting plate, the bearings can be easily replaced. This utility model, by being distributed around the periphery of the pier, enables convenient replacement of bridge bearings regardless of the distance between the bridge and the pier.
[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0026] like Figures 1-3 As shown in the figure, this utility model provides an auxiliary support device for bridge construction, including a ring plate 4, which is sleeved and fixed to the periphery of the pier 2, and the ring plate 4 is set near the top of the pier 2. Multiple embedded bars are connected to the inner side of the ring plate 4, and the embedded bars are located inside the pier 2.
[0027] A bridge bearing 3 is installed at the connection between the top of the pier 2 and the bottom of the bridge 1.
[0028] The annular plate 4 is fixedly connected to a plurality of evenly distributed fixing arms 5. The inner end of the fixing arm 5 is welded to the outer surface of the annular plate 4. The fixing arm 5 is arranged in a horizontal direction and has a hollow structure. The fixing arm 5 is provided with a plurality of stiffening plates inside to improve the connection strength between the fixing arm 5 and the annular plate 4.
[0029] The fixed arm 5 is equipped with a plug-in arm 6 that is slidably connected to it, and the plug-in arm 6 and the fixed arm 5 are detachably connected.
[0030] The plug arm 6 has a hollow structure. Inside the plug arm 6, two slide rods 7 are installed side by side. The axis of the slide rods 7 is set in the vertical direction. Linear bearings 8 are respectively sleeved on the slide rods 7. The linear bearings 8 are fixed inside the plug arm 6. The upper and lower end faces of the linear bearings 8 are flush with the upper and lower end faces of the plug arm 6.
[0031] A connecting plate 9 is installed at the bottom of the two sliding rods 7, and a lifting plate 10 is installed at the top of the two sliding rods 7. The sliding rods 7 and the connecting plate 9, and the sliding rods 7 and the lifting plate 10 are fixedly connected by a connecting seat 11.
[0032] The thickness of the lifting plate 10 is greater than the thickness of the connecting plate 9.

[0035] Both the fixed arm 5 and the plug-in arm 6 have a square cross-section along their longitudinal direction.
[0036] The specific working principle of this utility model is as follows:
[0037] When the bridge bearing 3 between pier 2 and bridge 1 needs to be replaced, the integrated structure consisting of the plug arm 6, hydraulic cylinder 12, lifting plate 10, and sliding rod 7 is installed on the fixed arm 5 on the periphery of pier 2. The hydraulic cylinder 12 drives the lifting plate 10 to rise. The two sliding rods 7 set on the left and right ensure the stability of the lifting plate 10 during the movement. After the lifting plate 10 raises bridge 1, it is convenient to replace the bridge bearing 3. After the bridge bearing 3 is replaced, the hydraulic cylinder 12 is reset and bridge 1 returns to the initial position.
