Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a road and bridge reinforcement device. Background Technology

[0002] Road and bridge reinforcement systems are comprehensive solutions that address existing bridge structural defects, insufficient load-bearing capacity, or decreased durability by employing specialized technologies and equipment to strengthen, repair, or renovate them. Their core objective is to extend the service life of bridges and ensure traffic safety by improving structural performance, adjusting internal force distribution, or enhancing material strength.

[0003] During bridge maintenance and construction, in order to minimize the risk of accidents, support devices are usually installed under the bridge. These devices support the bottom of the bridge, reduce the heavy pressure inside the bridge, and increase safety. Existing support devices are generally hydraulically driven, but due to the limited force-bearing area of ​​the hydraulic column, the support direction is prone to skew, which can cause the supported bridge to tilt, posing certain safety hazards during operation. Utility Model Content

[0004] Therefore, it is necessary to provide a road and bridge reinforcement device, which addresses the issue that while support devices are generally hydraulically driven, the limited force-bearing area of ​​the hydraulic column makes the support direction prone to skew, potentially causing the supported bridge to collapse and posing certain safety hazards during operation.

[0005] A road and bridge reinforcement device includes: a base, a bottom plate fixedly connected to the top of the base, hydraulic columns provided at the four corners of the top of the bottom plate, a connecting plate fixedly connected to the upper end of the plurality of hydraulic columns, and a support assembly provided above the connecting plate;

[0006] The bridge has multiple top plates, which are located on the same horizontal plane and are respectively positioned above the multiple support components to support the bridge.

[0007] In one embodiment, the interior of the base is a hollow structure, and the bottom plate is fixed above the hollow structure of the base.

[0008] In one embodiment, a plurality of support blocks are fixedly connected to the surface of the hydraulic column at equal intervals in a ring, and the lower part of the support blocks is fixedly connected to the upper part of the base plate.

[0009] In one embodiment, a limiting ring is fixedly connected to the surface of a plurality of the support blocks, and the limiting ring is sleeved on the surface of the hydraulic column.

[0010] In one embodiment, a plurality of limiting blocks are fixedly connected at equal intervals on the surface of the hydraulic column, and limiting rods are movably inserted into the surface of each of the limiting blocks, with the top ends of the limiting rods fixed below the connecting plate.

[0011] In one embodiment, the support assembly includes a support platform fixed above the connecting plate, with multiple support plates movably inserted inside the support platform. Each of the multiple support plates has a support plate fixedly connected above it, and the upper part of the support plate is attached to the lower part of the top plate.

[0012] In one embodiment, a top block is fixedly connected to one side of each of the plurality of support plates that are close to each other, and the top of each of the top blocks is in contact with the bottom of the support plate.

[0013] In one embodiment, multiple fixing bolts are threaded into the interior of each of the multiple support plates, and the multiple fixing bolts are respectively located above and below the support platform.

[0014] Beneficial effects

[0015] 1. Multiple hydraulic columns are vertically fixed to the upper surface of the base plate. The multiple hydraulic columns support upwards synchronously and are controlled by a unified controller to achieve synchronous lifting. The multiple hydraulic columns support the upper support components from multiple directions. A top plate is fixed on top of the multiple support components. The area of ​​the top plate is larger than the top area of ​​the hydraulic columns, which can better contact the bottom surface of the bridge. Multiple top plates can be installed according to actual needs and can be connected by buckles to increase structural stability. The multiple hydraulic columns greatly increase the contact area between the top plate and the bridge. The base disperses the downward pressure of the multiple hydraulic columns, improves the ground bearing capacity, reduces the possibility of the hydraulic columns tilting during operation, and greatly improves the safety of the hydraulic columns in use.

[0016] 2. The diameter of the support platform is larger than that of the connecting plate. The support platform limits the movement of multiple support plates, which in turn support the support plate above. The support plate then supports the top plate above. The distance between the support plate and the support platform is adjusted by the support plate to reduce the support distance of the hydraulic column and increase its safety. The surface of the support plate is arc-shaped, and the multiple support plates provide ring support, greatly increasing the structural strength. The bottom of the support plate increases the contact area with the support plate through a top block, enhancing the structural connection strength between the support plate and the support plate. This also improves the structural strength of the support plate, making it less prone to deformation. Fixing bolts limit the movement of the support plate both above and below, allowing for adjustment of the support height and improving safety. Attached Figure Description

[0029] The following is combined Figures 1-4 This utility model describes a road and bridge reinforcement device.

[0030] In one embodiment, a road and bridge reinforcement device includes: a base 100 and a plurality of top plates 500. A bottom plate 200 is fixedly connected above the base 100. Hydraulic columns 300 are provided at the four corners of the bottom plate 200. A connecting plate 301 is fixedly connected to the upper end of the plurality of hydraulic columns 300. A support assembly 400 is provided above the connecting plate 301. The plurality of top plates 500 are on the same horizontal plane. The plurality of top plates 500 are respectively provided above the plurality of support assemblies 400 for supporting the bridge.

[0031] In this embodiment, to support the bridge, the ground is typically leveled, and then the base 100 is laid on the ground. The base 100 supports the bottom plate 200. Multiple hydraulic columns 300 are bolted to the top of the bottom plate 200, and these hydraulic columns 300 are vertically fixed to the upper surface of the bottom plate 200. The multiple hydraulic columns 300 provide synchronous upward support, controlled by a unified controller to achieve synchronized lifting. The multiple hydraulic columns 300 support the upper support assembly 400 from multiple directions, and the upper support assembly 400 is fixed... The top plate 500 has a larger area than the top area of ​​the hydraulic column 300, allowing for better contact with the bridge's underside. Multiple top plates 500 can be installed according to actual needs and can be connected by clips to increase structural stability. The multiple hydraulic columns 300 greatly increase the contact area between the top plate 500 and the bridge. The base 100 disperses the downward pressure of the multiple hydraulic columns 300, improving the ground's load-bearing capacity and reducing the possibility of the hydraulic columns 300 tilting during operation, thus greatly improving the safety of the hydraulic columns 300 in use.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the interior of the base 100 has a hollow structure, the base plate 200 is fixed above the hollow structure of the base 100, and multiple support blocks 304 are fixedly connected in a ring at equal intervals on the surface of the hydraulic column 300. The lower part of the support block 304 is fixedly connected to the upper part of the base plate 200.

[0033] In this embodiment, the hollow structure of the base 100 increases the strength of the supporting structure of the base plate 200, making the base 100 less prone to deformation, and also increases the height of the base plate 200, reduces the support extension distance of the hydraulic column 300, and improves safety.

[0034] The support block 304 supports the bottom outer wall of the hydraulic column 300, increasing the structural strength of the bottom of the hydraulic column 300 and the connection strength between the bottom of the hydraulic column 300 and the base plate 200, thus greatly increasing safety.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a limiting ring 305 is fixedly connected to the surface of multiple support blocks 304. The limiting ring 305 is sleeved on the surface of the hydraulic column 300. Multiple limiting blocks 303 are fixedly connected at equal intervals on the surface of the hydraulic column 300. Limiting rods 302 are movably inserted into the surface of each of the multiple limiting blocks 303. The top ends of the multiple limiting rods 302 are fixed below the connecting plate 301.

[0036] In this embodiment, while supporting the hydraulic column 300, the surface of the support block 304 is limited by the limiting ring 305. The limiting ring 305 reinforces the surface of the hydraulic column 300 and increases the connection strength between the multiple support blocks 304, making the support block 304 less prone to deformation. The limiting rod 302 is used to limit the support direction of the hydraulic column 300, further increasing the structural strength of the hydraulic column 300 when it rises, and greatly increasing the safety of the hydraulic column 300 during use.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the support assembly 400 includes a support platform 401 fixed above the connecting plate 301. Multiple support plates 402 are movably inserted into the support platform 401. Each of the multiple support plates 402 is fixedly connected to a support plate 403 above it. The upper part of the support plate 403 is in contact with the lower part of the top plate 500.

[0038] In this embodiment, the diameter of the support platform 401 is larger than that of the connecting plate 301. The support platform 401 limits the movement of multiple support plates 402. The support plate 403 supports the upper plate 500 above the multiple support plates 402. The distance between the support plate 402 and the support platform 401 is adjusted by the support plate 402 to reduce the support distance of the hydraulic column 300 and increase the safety of the hydraulic column 300. The surface of the support plate 402 is arc-shaped, and the multiple support plates 402 provide ring support, which greatly increases the structural strength.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, a top block 404 is fixedly connected to one side of the multiple support plates 402 that are close to each other. The top of the multiple top blocks 404 is attached to the bottom of the support plate 403. Multiple fixing bolts 405 are threaded into the interior of the multiple support plates 402. The multiple fixing bolts 405 are located above and below the support platform 401 respectively.

[0040] In this embodiment, the bottom of the support plate 403 increases the contact area with the support plate 402 through the top block 404, which strengthens the structural connection between the support plate 402 and the support plate 403, and at the same time improves the support structure strength of the support plate 402, making the support plate 402 less prone to deformation. The fixing bolt 405 limits the upper and lower parts of the support plate 402, which is used to adjust the support height of the support plate 402 and improve safety.

[0041] Working principle:

[0042] When supporting the bottom of the bridge, multiple hydraulic columns 300 support the support assembly 400 and the top plate 500. The top plate 500 supports the bridge through multiple support points. The bottoms of the multiple hydraulic columns 300 are supported by the base 100 and the bottom plate 200, which disperses the downward pressure of the hydraulic columns 300 and reduces the compression of the hydraulic columns 300 on the ground. The support height of the base 100, the bottom plate 200 and the support assembly 400 reduce the support distance of the hydraulic columns 300, thereby reducing the surface pressure of the columns during the support process. This greatly increases the safety of the hydraulic columns 300 in use, making them less prone to tilting and improving safety.

[0043] It should be noted that the hydraulic column 300 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the hydraulic column 300 can be powered by an internal power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
