Description

Technical Field

[0001] This utility model relates to the field of bridge jacking technology, specifically a leveling device suitable for bridge jacking. Background Technology

[0002] Bridge jacking refers to the use of an overall hydraulic synchronous lifting scheme. This involves utilizing the existing cast-in-place piles for support without damaging the original bridge deck pavement, railings, sidewalks, or the connections between beams and slabs. First, a "hydraulic lifting" device is used to support the entire superstructure of the bridge. Then, the columns under each pier and abutment cap beam are cut off, and the "hydraulic lifting" device is operated again to raise the entire bridge to the design height. Finally, the steel reinforcement of the columns is extended, formwork is erected, and the second phase of concrete is poured.

[0003] Chinese Patent Publication No. CN207933906U discloses "A Small Bridge Lifting Device," which includes a jack body. The jack body includes a drive shaft, and a leveling device is provided on the surface of the jack body away from the drive shaft. The leveling device includes a first base plate and a second base plate for connecting the jack body. Multiple sleeves are provided circumferentially on the surface of the second base plate away from the jack body. Multiple threaded screws are provided on the first base plate, which are inserted into each sleeve and threadedly connected to the sleeves. A rotating component is fixedly connected to the end of the threaded screw away from the sleeve. The rotating component is rotatably connected to the first base plate. When it is necessary to lift the upper part of the bridge, the first base plate is placed on the bottom surface, and the rotating component is rotated. The sleeves threadedly engaged with the threaded screws can move on the threaded screws. By rotating the multiple threaded screws, the height of various positions on the second base plate is adjusted, thereby leveling the jack body and preventing the jack body from causing eccentricity when lifting the upper part of the bridge.

[0004] While existing technologies can be lifted during use, they are inconvenient to move during operation. The equipment needs to be moved by auxiliary equipment such as cranes or forklifts, which increases the time required for relocation and may prolong the overall construction period. At the same time, they cannot provide effective support during operation. The lack of additional support points means that the stability of the entire system depends on the foundation structure itself. For heavy loads or unstable foundations, they cannot provide sufficient support force, which can easily lead to equipment overturning or displacement. Utility Model Content

At the same time, it cannot provide effective support during use. The lack of additional support points means that the stability of the entire system depends on the foundation structure itself. For heavy loads or unstable foundations, it cannot provide sufficient support force, which can easily lead to the overturning or displacement of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A leveling device suitable for bridge jacking includes a vehicle body, a buffer assembly at the bottom of the vehicle body, and support assemblies on both sides of the vehicle body.

[0008] The buffer assembly includes multiple rollers, and a rotating column is fixedly connected to one side of the outer surface of each roller. Multiple base plates are fixedly connected to the bottom of the outer surface of the vehicle body, and a first fixing frame is fixedly connected to one side of the outer surface of each base plate. A first connecting column is rotatably embedded inside each of the multiple first fixing frames, and a first connecting frame is rotatably sleeved on the outer surface of each of the multiple first connecting columns.

[0009] The support assembly includes multiple support discs, and a support block is fixedly connected to the top of the outer surface of each of the multiple support discs. A first support column is movably connected to the inner side of the support block. Upper fixing blocks are fixedly connected to both sides of the outer surface of the vehicle body. Upper rotating columns are rotatably embedded inside the multiple upper fixing blocks. Upper support arms are rotatably sleeved on the outer surface of the multiple upper rotating columns.

[0010] Preferably, a first connecting block is fixedly connected to one side of the outer surface of each of the plurality of first connecting frames, and a support frame is fixedly connected to one side of the outer surface of each of the plurality of first connecting blocks, and a sleeve is fixedly connected to one side of the outer surface of each of the plurality of support frames, and the plurality of rotating columns are rotatably embedded inside the sleeve.

A shock-absorbing hydraulic rod is rotatably sleeved on the outer surface of each of the plurality of second connecting columns, and a third connecting column is rotatably embedded inside the plurality of shock-absorbing hydraulic rods. A third fixing frame is fixedly connected to one side of the outer surface of each of the plurality of first connecting frames, and the plurality of third connecting columns are rotatably embedded inside the third fixing frames. A spring is wound around the outer surface of each of the plurality of shock-absorbing hydraulic rods.

[0012] Preferably, the interior of each of the plurality of upper support arms is rotatably fitted with a first connecting rod, and the exterior of each of the plurality of first connecting rods is rotatably fitted with a support plate, and the plurality of first support columns are rotatably fitted inside the support plate.

[0013] Preferably, both sides of the outer surface of the vehicle body are fixedly connected to lower fixing blocks, and each of the lower fixing blocks has a lower rotating column rotatably embedded inside.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] 1. When encountering uneven ground, the roller movement device is driven by multiple support frames, which then drive the rollers to the first connecting frame. Multiple shock-absorbing hydraulic rods and springs dampen the rollers, thereby improving the stability of the device. This technical solution absorbs some energy when encountering uneven ground or sudden impacts, thereby reducing the impact of vibration on the equipment and bridge structure and helping to protect the device from damage.

[0018] 2. Before the lifting hydraulic rods are used for lifting, multiple supporting hydraulic rods are activated. These supporting hydraulic rods drive the push blocks to move, which in turn rotates the upper and lower supporting arms and the upper and lower rotating columns. This makes the upper and lower supporting arms horizontal with the ground, bringing the support plate into contact with the ground. The supporting hydraulic rods then continue to drive the support plate to remain firmly in contact with the ground, thereby lifting the vehicle body and preventing the rollers from slipping on the ground. This technical solution increases the load-bearing capacity and stability, lowers the center of gravity, improves the anti-overturning ability, increases the contact area of ​​the support plate, reduces the pressure on the soft foundation, and prevents ground collapse during construction.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 A leveling device suitable for bridge jacking includes a vehicle body 1, a buffer assembly at the bottom of the vehicle body 1, and support assemblies on both sides of the vehicle body 1.

[0026] The buffer assembly includes multiple rollers 2, and a rotating column 307 is fixedly connected to one side of the outer surface of each roller 2. Multiple base plates 3 are fixedly connected to the bottom of the outer surface of the vehicle body 1, and a first fixing frame 301 is fixedly connected to one side of the outer surface of each base plate 3. A first connecting column 302 is rotatably embedded inside each of the multiple first fixing frames 301, and a first connecting frame 303 is rotatably sleeved on the outer surface of each of the multiple first connecting columns 302.

[0027] The support assembly includes multiple support discs 8, and each of the multiple support discs 8 has a support block 802 fixedly connected to the top of its outer surface. The support block 802 has a first support column 801 movably connected to its inner side. Both sides of the outer surface of the vehicle body 1 have upper fixing blocks 501 fixedly connected to each other. Each of the multiple upper fixing blocks 501 has an upper rotating column 502 rotatably embedded inside it. Each of the multiple upper rotating columns 502 has an upper support arm 5 rotatably sleeved on its outer surface.

[0028] Through the above technical solution, when the roller 2 moving device encounters uneven ground, it is driven by multiple support frames 305, and then driven to the first connecting frame 303 through the support frames 305. Multiple shock-absorbing hydraulic rods 4 and springs 401 provide shock absorption for the roller 2, thereby improving the stability of the device. Through the above technical solution, some energy is absorbed when encountering uneven ground or sudden impact, thereby reducing the impact of vibration on equipment and bridge structure, and helping to protect the device from damage.

[0029] Through the above technical solution, before the lifting hydraulic rod 9 is lifted, multiple supporting hydraulic rods 7 are activated. These supporting hydraulic rods 7 drive the push block 701 to move. The movement of the push block 701 causes the upper supporting arm 5 and the lower supporting arm 6, as well as the upper rotating column 502 and the lower rotating column 602, to rotate. This makes the upper supporting arm 5 and the lower supporting arm 6 horizontal with the ground, thus bringing the support plate 8 into contact with the ground. The supporting hydraulic rods 7 then continue to drive the support plate 8 to remain firmly in contact with the ground, thereby supporting and lifting the vehicle body 1 and preventing the roller 2 from slipping when in contact with the ground. Through the above technical solution, its load-bearing capacity and stability are increased, the center of gravity is lowered, and the anti-overturning ability is improved. The support plate 8 increases the contact area, reduces the pressure on the soft foundation, and prevents the ground from collapsing during construction.

[0030] Specifically, a first connecting block 304 is fixedly connected to one side of the outer surface of a plurality of first connecting frames 303, and a support frame 305 is fixedly connected to one side of the outer surface of a plurality of first connecting blocks 304, a sleeve 306 is fixedly connected to one side of the outer surface of a plurality of support frames 305, and a plurality of rotating columns 307 are rotatably embedded inside the sleeve 306.

[0031] Through the above technical solution, the transmission is carried out through multiple support frames 305, and the transmission is carried to the first connecting frame 303 through the support frames 305.

[0032] Specifically, a second fixing frame 402 is fixedly connected to one side of the outer surface of multiple base plates 3, and a second connecting column 403 is rotatably embedded inside the multiple second fixing frames 402. A shock-absorbing hydraulic rod 4 is rotatably sleeved on the outer surface of multiple second connecting columns 403, and a third connecting column 405 is rotatably embedded inside the multiple shock-absorbing hydraulic rods 4. A third fixing frame 404 is fixedly connected to one side of the outer surface of multiple first connecting frames 303, and multiple third connecting columns 405 are rotatably embedded inside the third fixing frame 404. A spring 401 is wound and sleeved on the outer surface of multiple shock-absorbing hydraulic rods 4.

[0033] The above technical solution uses multiple shock-absorbing hydraulic rods 4 and springs 401 to dampen and buffer the rollers 2.

[0034] Specifically, a first connecting rod 503 is rotatably embedded inside the multiple upper support arms 5, and a support plate 803 is rotatably sleeved on the outer surface of the multiple first connecting rods 503, and multiple first support columns 801 are rotatably embedded inside the support plate 803.

[0035] The above technical solution uses the upper support arm 5 for support.

[0036] Specifically, both sides of the outer surface of the vehicle body 1 are fixedly connected to lower fixing blocks 601, and lower rotating columns 602 are rotatably embedded inside the multiple lower fixing blocks 601. Lower support arms 6 are rotatably sleeved on the outer surface of the multiple lower rotating columns 602, and second connecting rods 603 are rotatably embedded inside the multiple lower support arms 6. The multiple second connecting rods 603 are rotatably embedded inside the support plate 803.

[0037] The above technical solution uses the lower support arm 6 for support.

[0038] Specifically, both sides of the outer surface of the vehicle body 1 are fixedly connected to a middle fixing block 702, and a third connecting rod 703 is rotatably embedded inside the middle fixing block 702. The outer surface of the third connecting rod 703 is rotatably fitted with a supporting hydraulic rod 7, and a push block 701 is fixedly connected to one side of the outer surface of the supporting hydraulic rod 7. The first connecting rod 503 is rotatably embedded inside the push block 701.

[0039] Through the above technical solution, multiple supporting hydraulic rods 7 drive the push block 701 to move, and the movement of the multiple push blocks 701 drives the upper supporting arm 5 and the lower supporting arm 6, and the upper rotating column 502 and the lower rotating column 602 to rotate.

[0040] Specifically, multiple lifting hydraulic rods 9 are fixedly connected to the top of the outer surface of multiple vehicle bodies 1, and lifting plates 901 are fixedly connected to the top of the outer surface of each of the multiple lifting hydraulic rods 9.

[0041] The above technical solution involves lifting using the lifting hydraulic rod 9.

[0042] In use, the roller 2 moving device, when encountering uneven ground, is driven by multiple support frames 305, which in turn drive the first connecting frame 303. Multiple shock-absorbing hydraulic rods 4 and springs 401 dampen the roller 2, thereby improving the stability of the device. This technical solution absorbs some energy when encountering uneven ground or sudden impacts, reducing the impact of vibration on the equipment and bridge structure, and helping to protect the device from damage. Before the lifting hydraulic rod 9 is lifted, multiple support hydraulic rods 7 are activated, which in turn move the push block 701. The movement of multiple push blocks 701 drives the rotation of multiple upper support arms 5 and lower support arms 6, and the rotation of upper and lower rotating columns 502 and 602, thereby turning the upper support arms 5 and lower support arms 6 to be horizontal with the ground, thus bringing the support plate 8 into contact with the ground. Then, the support hydraulic rod 7 continues to drive the support plate 8 to keep it in close contact with the ground, thereby supporting and lifting the vehicle body 1 and preventing the rollers 2 from slipping when in contact with the ground. Through the above technical solution, its load-bearing capacity and stability are increased, the center of gravity is lowered, and the anti-overturning ability is improved. The support plate 8 increases the contact area, reduces the pressure on the soft foundation, and prevents the ground from collapsing during construction.
