Description

[Technical Field]

[0001] This utility model relates to the technical field of bridge reinforcement equipment, specifically to a distributed load-bearing reinforcement device for bridges used by heavy transport vehicles. [Background Technology]

[0002] Currently, during the transportation of large equipment in the power, chemical, and wind power sectors, the total weight of the transport vehicles often far exceeds the design load standards of many small- and medium-span bridges. To ensure the structural safety of the bridge and the smooth passage of traffic, temporary reinforcement of the bridge is necessary.

[0003] Common temporary reinforcement methods mainly involve erecting full-span scaffolding or using a small number of simple support columns under the bridge. While full-span scaffolding provides reliable support, it suffers from significant drawbacks, including large-scale erection and dismantling work, excessive time consumption, high material costs, and significant interference with the space under the bridge (such as waterways and roads), resulting in low efficiency and poor economic returns. Simple support columns, on the other hand, generally suffer from insufficient stability, small contact area with the bridge deck leading to excessive local compressive stress, inflexible height adjustment, and loose fixing prone to slippage, making it difficult to provide safe, uniform, and reliable effective support.

[0004] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0005] The technical problem to be solved by this utility model is to provide a distributed load-bearing reinforcement device for bridges used by heavy transport vehicles. This device has the advantages of convenient assembly and disassembly, adjustable height, reasonable support distribution, convenient transportation and reusability, and solves the problems of inconvenient assembly and disassembly and unreliable support in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model proposes a distributed load-bearing reinforcement device for bridges used by heavy transport vehicles, comprising:

[0007] Base 1;

[0008] The pile foundation 2 is composed of several vertically connected pile sections 20. The bottom pile section 20 is detachably mounted on the base 1, and the top pile section 20 is fixedly provided with mounting blocks 21 on both the left and right sides of the top.

[0009] The bearing component 3 is detachably installed on the top of the pile foundation 2 and fixedly connected to the mounting block 21. The bearing component 3 includes:

[0010] The first connecting and fixing block 4 is located on the top side of the pile foundation 2. The first connecting and fixing block 4 has a first groove 40 formed in the middle so that the top side of the pile foundation 2 can be embedded. The first connecting and fixing block 4 has a first connecting plate 41 formed on both sides to connect with the corresponding mounting block 21.

[0011] The second connecting and fixing block 5 is located on the top of the pile foundation 2 and on the other side opposite to the first connecting and fixing block 4. The second connecting and fixing block 5 has a second groove 50 formed in the middle so that one side of the top of the pile foundation 2 can be embedded. The second connecting and fixing block 5 has a second connecting plate 51 formed on both sides to connect with the corresponding mounting block 21.

[0012] Adjustable fixing member 6 is provided on the corresponding mounting block 21, and is used to fix the first connecting plate 41 and the second connecting plate 51 on the same side in an adjustable manner on the corresponding mounting block 21, so that the first connecting fixing block 4 and the second connecting fixing block 5 clamp the top of the pile foundation 2;

[0013] The first connecting block 4 is fixedly provided with a first support frame 42 for supporting the bridge bottom on its outer side, and the second connecting block 5 is fixedly provided with a second support frame 52 for supporting the bridge bottom on its outer side.

[0014] As described above, a distributed load-bearing reinforcement device for a bridge for heavy transport vehicles includes an adjusting fastener 6 consisting of several bolts and nuts threaded to them. Several vertically arranged fixing holes 60 are provided on the first connecting plate 41, the mounting block 21, and the second connecting plate 51. The bolts pass through the fixing holes 60 in the first connecting plate 41, the mounting block 21, and the second connecting plate 51 in sequence and are then connected to the corresponding nuts to fix the first connecting fixing block 4 and the second connecting fixing block 5 in a set position, thereby pressing the first support frame 42 and the second support frame 52 tightly against the bottom of the bridge.

[0015] As described above, a distributed load-bearing reinforcement device for a bridge for heavy transport vehicles has a "T" shaped structure for the first support frame 42 and the second support frame 52.

[0016] As described above, in a distributed load-bearing reinforcement device for a bridge for heavy transport vehicles, the first support frame 42 is connected to the first connecting and fixing block 4 by welding, and the second support frame 52 is fixedly connected to the second connecting and fixing block 5 by welding.

[0017] As described above, in a distributed load-bearing reinforcement device for a bridge for heavy transport vehicles, the mounting block 21 is fixedly connected to the pile foundation 2 by welding.

[0018] As described above, a distributed load-bearing reinforcement device for a bridge for heavy transport vehicles includes a fixed sleeve 7 that can slide up and down on one of the pile sections 20. The fixed sleeve 7 has several support rod assemblies 8 around its periphery. The lower end of the support rod assembly 8 is connected to the base 1, and the upper end of the support rod assembly 8 is connected to the side of the fixed sleeve 7.

[0019] As described above, a distributed load-bearing reinforcement device for a bridge for heavy transport vehicles includes a support rod assembly 8 which is a telescopic structure comprising an upper support rod 80 and a lower support rod 81. The upper support rod 80 is telescopically inserted into the lower support rod 81 and can be locked in a set position. The top of the upper support rod 80 is hinged to the fixing sleeve 7, and the lower support rod 81 is hinged to the base 1.

[0020] As described above, a distributed load-bearing reinforcement device for a bridge for heavy transport vehicles has rubber pads 9 on the top of both the first support frame 42 and the second support frame 52.

[0021] Compared with existing technologies, the distributed load-bearing reinforcement device for bridges used by heavy transport vehicles of this utility model has the following advantages:

[0022] 1. The distributed load-bearing reinforcement device of this application can be carried by transport vehicles. When the transport vehicle passes over small and medium-sized bridges, workers install the distributed load-bearing reinforcement device on-site at the mid-span of the bridge bottom to support the bridge bottom. After the vehicle passes, it is disassembled and then taken away by the transport vehicle for future use. By adopting segmented pile foundations and detachable load-bearing components, it is easy to carry by transport vehicles, can be quickly assembled and disassembled on-site, has a high reuse rate, significantly improves construction efficiency, and reduces costs.

[0023] 2. In this application, by fixing an installation block at the top of the pile foundation, the first connecting fixing block and the second connecting fixing block are connected to the installation block and clamp the top of the pile foundation. Compared with the previous method of directly clamping the pile foundation, this effectively prevents the first connecting fixing block and the second connecting fixing block from sliding down the pile foundation after being subjected to force, making the support more reliable.

[0024] 3. In this application, the first support frame and the second support frame are respectively set on the outside of the first connecting fixing block and the second connecting fixing block, which increases the distance between the two support frames, thereby expanding the support contact area with the bottom of the bridge, realizing distributed uniform load bearing, avoiding single-point stress concentration, and providing better protection for the bridge.

[0025] 4. This application also includes a fixed sleeve and a telescopic support rod assembly to support the pile foundation, which greatly enhances the anti-tilting ability of the pile foundation and ensures the overall stability of the device when subjected to vertical loads.

Detailed Implementation Methods

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1-5As shown, this utility model discloses a distributed load-bearing reinforcement device for bridges used by heavy transport vehicles, comprising a base 1, pile foundations 2, and a load-bearing component 3. The pile foundation 2 is composed of several vertically connected pile sections 20. The bottom pile section 20 is detachably mounted on the base 1, and mounting blocks 21 are fixedly installed on both the left and right sides of the top of the top pile section 20. The mounting blocks 21 are fixedly connected to the pile foundation 2 by welding. The load-bearing component 3 is detachably installed on the top of the pile foundation 2 and fixedly connected to the mounting blocks 21. The bearing assembly 3 includes a first connecting fixing block 4, a second connecting fixing block 5, an adjusting fixing member 6, a first support frame 42, and a second support frame 52. The first connecting fixing block 4 is located on one side of the top of the pile foundation 2. A first groove 40 is formed in the middle of the first connecting fixing block 4 so that one side of the top of the pile foundation 2 can be embedded. First connecting plates 41 connected to corresponding mounting blocks 21 are formed on both sides of the first connecting fixing block 4. The second connecting fixing block 5 is located on the top of the pile foundation 2, on the other side opposite to the first connecting fixing block 4. A second groove 50 is formed in the middle of the second connecting fixing block 5 so that one side of the top of the pile foundation 2 can be embedded. Second connecting plates 51 connected to corresponding mounting blocks 21 are formed on both sides of the second connecting fixing block 5. The adjusting fixing member 6 is located on the corresponding mounting block 21 and is used to fix the first connecting plate 41 and the second connecting plate 51 on the same side in an adjustable manner on the corresponding mounting block 21 so that the first connecting fixing block 4 and the second connecting fixing block 5 clamp the top of the pile foundation 2. The first support frame 42 is fixed to the outside of the first connecting block 4 to support the bridge bottom, and the second support frame 52 is fixed to the outside of the second connecting block 5 to support the bridge bottom. It should be noted that the pile sections 20 can be connected and fixed using flanges.

[0038] The distributed load-bearing reinforcement device of this application can be carried by transport vehicles. When the transport vehicle passes over small and medium-sized bridges, workers install the distributed load-bearing reinforcement device on-site at the mid-span of the bridge bottom to support the bridge bottom. After the vehicle passes, it is disassembled and then taken away by the transport vehicle for future use. By adopting segmented pile foundations 2 and detachable load-bearing components 3, it is easy to carry by transport vehicles, can be quickly assembled and disassembled on-site, has a high reuse rate, significantly improves construction efficiency, and reduces costs.

[0039] In this application, by fixing an installation block 21 on the top of the pile foundation 2, the first connecting fixing block 4 and the second connecting fixing block 5 are connected to the installation block 21 and clamp the top of the pile foundation 2. Compared with the previous method of directly clamping the pile foundation 2, this can prevent the first connecting fixing block 4 and the second connecting fixing block 5 from sliding down the pile foundation 2 after being subjected to force, thus preventing them from failing to support the bridge.

[0040] In addition, in this application, the first support frame 42 is fixed to the outside of the first connecting fixing block 4, and the second support frame 52 is fixed to the outside of the second connecting fixing block 5. Compared with the top of the pile foundation 2, which is directly set on the top, the distance between the first support frame 42 and the second support frame 52 can be larger, thereby making the bearing area of ​​the first support frame 42 and the second support frame 52 and the bottom of the bridge larger, playing a better supporting role and preventing the load from being applied only at a single point.

[0041] like Figure 3 , Figure 4 As shown, as a further embodiment, the adjusting fastener 6 consists of several bolts and nuts threadedly connected to them. The first connecting plate 41, the mounting block 21, and the second connecting plate 51 are each provided with several vertically arranged fixing holes 60. The bolts pass through the fixing holes 60 in the first connecting plate 41, the mounting block 21, and the second connecting plate 51 in sequence and are then connected to the corresponding nuts to fix the first connecting fixing block 4 and the second connecting fixing block 5 in a set position, thereby pressing the first support frame 42 and the second support frame 52 tightly against the bottom of the bridge. In this embodiment, by splicing several pile sections 20 together and adjusting them to an approximate height, the adjusting fastener 6 is used to fix the first connecting fixing block 4 and the second connecting fixing block 5 at the positions of the corresponding fixing holes 60, so that the tops of the first support frame 42 and the second support frame 52 are pressed tightly against the bottom of the bridge, thus supporting the bridge.

[0042] like Figure 3 , Figure 4 As shown, as a further embodiment, the first support frame 42 and the second support frame 52 are in a "T" shape to increase the contact area with the bottom of the bridge, making the support more uniform and stable. Furthermore, the first support frame 42 is connected to the first connecting fixing block 4 by welding, and the second support frame 52 is fixedly connected to the second connecting fixing block 5 by welding, ensuring connection strength.

[0043] like Figure 1 , Figure 2 and Figure 5 As shown in the figure, as a further embodiment, a fixed sleeve 7 that can slide up and down is also fitted on one of the pile sections 20. A plurality of support rod assemblies 8 are provided around the fixed sleeve 7. The lower end of each support rod assembly 8 is connected to the base 1, and the upper end of each support rod assembly 8 is connected to the side of the fixed sleeve 7. In this embodiment, by setting the fixed sleeve 7 and the support rod assembly 8 in cooperation, the support rod assembly 8 can protect the pile foundation 2 through the fixed sleeve 7, thereby improving the overall stability of the pile foundation 2 and preventing the pile foundation 2 from collapsing to one side.

[0044] Furthermore, the support rod assembly 8 is a telescopic structure, including an upper support rod 80 and a lower support rod 81. The upper support rod 80 is telescopically inserted into the lower support rod 81 and can be locked in a set position. The top of the upper support rod 80 is hinged to the fixing sleeve 7, and the lower support rod 81 is hinged to the base 1. By making the support rod assembly 8 telescopic, if the height of the bridge bottom is high, the upper support rod 80 and the lower support rod 81 can be adjusted so that the fixing sleeve 7 is located in the middle of the pile foundation 2, thus providing better support. It should be noted that the fixing sleeve 7 can also be set in two parts, left and right, connected by bolts to clamp the pile section 20. It should be noted that the upper support rod 80 and the lower support rod 81 can be locked in a set position by screws, which are not shown in the figure.

[0045] like Figure 1 As shown, as a further embodiment, both the first support frame 42 and the second support frame 52 are provided with rubber pads 9 on their tops. By providing rubber pads 9, damage to the bridge bottom surface is avoided by the first support frame 42 and the second support frame 52 making hard contact with the bridge bottom, and the friction is increased, further improving the stability of the support.
