In the using process, when one side of the top face of the web beam is subjected to overload pressure, the second supporting plate on the same side can be pressed downwards, then the first supporting plate on the same side is made to move downwards, and therefore the moving ends of the first hydraulic cylinders on the same side are made to return. And at the moment, hydraulic oil in the rodless cavities of the first hydraulic cylinders on the same side can enter the rodless cavities of the second hydraulic cylinders on the same side, and then the moving ends of the second hydraulic cylinders on the same side stretch out.

Due to the fact that hydraulic pressure is adopted as a power source, enough supporting force can be provided for the bottom face and the two side faces of the web beam, and then the anti-overturning performance is improved.

Description

Technical Field

[0001] The present application relates to the technical field of steel-concrete composite beams, and in particular to a steel-concrete composite beam bridge deck reinforcement device. Background Art

[0002] Related technology (Announcement No.: CN112342940B) discloses a steel-concrete composite beam bridge deck reinforcement device, including a web beam and a cap beam. Ear plates are provided on the side of the web beam, a pressure plate is provided on the side of the web beam below the ear plates, and a pair of tie rods 1 are hinged on both sides of the ear plates via pins. A T-shaped welded plate is provided on the top of the cap beam, and a pair of tie rods 2 are hinged on both sides of the T-shaped welded plate via pins. Multiple compression springs are horizontally provided on the side of the pressure plate, the ends of the compression springs are connected to a fixed bar, and the ends of tie rods 1 and 2 are hinged to the fixed bar via pins.

[0003] In the process of implementing the technical solution of the present disclosure, it was found that there are at least the following problems in the related technology:

[0004] This steel-concrete composite beam bridge deck reinforcement device improves the integrity between the web beam and the cap beam through the aforementioned structure. When overload pressure is applied to one side laterally, tie rods 1 and 2 bend inward, distributing the force to multiple compression springs. This causes the compression springs to slightly compress, which in turn distributes the pressure to the web beam, enhancing the bridge's lateral anti-overturning resistance and preventing the beam from falling. However, due to the inherent performance of the compression springs, they are unable to provide sufficient thrust to the web beam when the deformation is small, resulting in poor anti-overturning performance.

[0018] The disclosed technical solution provides a steel-concrete composite beam bridge deck reinforcement device that can achieve the following technical effects:

[0019] The disclosed technical solution provides a steel-concrete composite beam bridge deck reinforcement device for use between a cap beam with a groove on its top surface and a web beam located above the cap beam. The device comprises a sealing plate, a first hydraulic cylinder, a first support plate, a first optical axis, a second support plate, a first support, a first pivot arm, and a second hydraulic cylinder. The sealing plate is mounted on the top surface of the cap beam to seal the groove and prevent debris from entering the groove. The first hydraulic cylinder is mounted on the bottom surface of the groove along the height of the cap beam and located on either side of the groove along the length of the cap beam, each providing support for the bottom surface of the web beam. The first support plates are mounted on the movable ends of the first hydraulic cylinders on both sides and are located within the groove. The first optical axis is evenly mounted on the top surface of the first support plates on both sides along the height of the cap beam and slidably extends through the sealing plate, allowing for both to move up and down relative to the sealing plate. The sealing plate includes multiple through-holes for the passage of the multiple first optical axes. The second support plates are mounted on the top ends of the multiple first optical axes on both sides, each of which is designed to abut against the bottom surface of the web beam, thereby supporting the web beam. The first support is mounted on the top surface of the sealing plate, along the length of the cap beam, on either side of the sealing plate. The first supports on either side are used to support and mount a rotatable first pivot arm. The first pivot arm is rotatably mounted on each of the first supports, allowing rotational movement relative to the first supports. One end of each first pivot arm is movably inserted through the sealing plate, which includes two strip-shaped holes for the pivot arms to pass through. The other ends of each first pivot arm clamp onto the two side surfaces of the web beam, providing support for the two sides of the web beam. The second hydraulic cylinder is rotatably mounted between one end of each first pivot arm located within the groove and the bottom surface of the groove. It can rotate relative to the bottom surface of the groove and one end of each first pivot arm located within the groove, providing support for the two sides of the web beam. The oil inlet of each second hydraulic cylinder is connected to the oil inlet of each first hydraulic cylinder, and the oil return port of each second hydraulic cylinder is connected to the oil return port of each first hydraulic cylinder, allowing hydraulic oil to circulate between the second and first hydraulic cylinders. When the web beam is in a balanced state, hydraulic oil is stored in the rod chambers and rodless chambers of the second hydraulic cylinder and the first hydraulic cylinder on both sides.

[0020] During use, when one side of the top surface of the web beam is subjected to overload pressure, the second support plate on the same side can be pressed down. Driven by the first optical axis on the same side, the first support plate on the same side can move downward, thereby causing the moving end of the first hydraulic cylinder on the same side to retract. At this time, the hydraulic oil in the rodless chamber of the first hydraulic cylinder on the same side can enter the rodless chamber of the second hydraulic cylinder on the same side, and the hydraulic oil in the rod chamber of the second hydraulic cylinder on the same side can enter the rod chamber of the first hydraulic cylinder on the same side, thereby causing the moving end of the second hydraulic cylinder on the same side to extend. Then, supported by the first support on the same side, the first rotating arm on the same side can deflect toward the direction of the web beam. This increases the support force on the side of the web beam, enhances the lateral anti-overturning ability of the bridge, and prevents the beam from falling off. Since hydraulic pressure is used as the power source, sufficient support force can be provided to the bottom surface and two side surfaces of the web beam, thereby improving the anti-overturning ability.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0041] Combine Figures 1 to 8As shown, an embodiment of the present disclosure provides a steel-concrete composite beam bridge deck reinforcement device, which is applied between a cap beam 1 having a groove on its top surface and a web beam 2 located above the cap beam 1. The device comprises a sealing plate 3, a first hydraulic cylinder 4, a first support plate 5, a first optical axis 6, a second support plate 7, a first support 8, a first pivot arm 9, and a second hydraulic cylinder 10. The sealing plate 3 is mounted on the top surface of the cap beam 1 to seal the groove and reduce the ingress of debris into the groove. The first hydraulic cylinder 4 is mounted on the bottom surface of the groove along the height direction of the cap beam 1 and is located on both sides of the groove along the length direction of the cap beam 1, each providing support for the bottom surface of the web beam 2. The first support plates 5 are mounted on the movable ends of the first hydraulic cylinders 4 on both sides and are both located within the groove. The first optical axes 6 are evenly mounted on the top surfaces of the first support plates 5 on both sides along the height direction of the cap beam 1 and are slidably inserted through the sealing plate 3, allowing both to move up and down relative to the sealing plate 3. The sealing plate 3 includes multiple through-holes for passing the multiple first optical axes 6. Second support plates 7 are mounted on the tops of the multiple first optical axes 6 on either side. Each second support plate 7 is designed to abut against the bottom surface of the web beam 2, thereby supporting the web beam 2. First supports 8 are mounted on the top surface of the sealing plate 3, located on either side of the sealing plate 3 along the length of the cap beam 1. Each first support 8 is used to support a rotatable first pivot arm 9. The first pivot arm 9 is rotatably mounted on each first support 8, allowing rotational movement relative to each first support 8. One end of each first pivot arm 9 is movably inserted through the sealing plate 3, which includes two strip-shaped holes for passing through the pivot arms. The other ends of each first pivot arm 9 clamp onto the two side surfaces of the web beam 2, providing support for the two sides of the web beam 2. Second hydraulic cylinders 10 are rotatably mounted between one end of each first pivot arm 9 located within the groove and the bottom surface of the groove. They can rotate relative to the bottom surface of the groove and one end of each first pivot arm 9 located within the groove, providing support for the two sides of the web beam 2. The oil inlets of the second hydraulic cylinders 10 on both sides are respectively connected to the oil inlets of the first hydraulic cylinders 4 on both sides, and the oil return ports of the second hydraulic cylinders 10 on both sides are respectively connected to the oil return ports of the first hydraulic cylinders 4 on both sides, so that the hydraulic oil circulates between the second hydraulic cylinders 10 on both sides and the first hydraulic cylinders 4. When the web beam 2 is in a balanced state, hydraulic oil is stored in the rod chambers and rodless chambers of the second hydraulic cylinders 10 and the first hydraulic cylinders 4 on both sides.

[0042] The disclosed embodiments provide a steel-concrete composite beam bridge deck reinforcement device. When one side of the top surface of the web beam 2 is subjected to overload pressure, the second support plate 7 on the same side is pressed downward. Driven by the first optical axis 6 on the same side, the first support plate 5 on the same side moves downward, causing the movable end of the first hydraulic cylinder 4 on the same side to retract. At this point, the hydraulic oil in the rodless chamber of the first hydraulic cylinder 4 on the same side enters the rodless chamber of the second hydraulic cylinder 10 on the same side, and the hydraulic oil in the rod chamber of the second hydraulic cylinder 10 on the same side enters the rod chamber of the first hydraulic cylinder 4 on the same side, thereby extending the movable end of the second hydraulic cylinder 10 on the same side. Then, supported by the first support 8 on the same side, the first rotating arm 9 on the same side deflects toward the web beam 2. This increases the support force on the side of the web beam 2, enhances the bridge's lateral anti-overturning performance, and prevents the beam from falling. Because hydraulic power is used as the power source, sufficient support force is provided to the bottom and both sides of the web beam 2, thereby improving anti-overturning performance.

[0043] Optionally, combined Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 As shown, the structure further includes a guide rail 11, a slider 12, a movable plate 13, a first connecting rod 14, a second optical axis 15, a second pivot arm 16, and a second connecting rod 17. The guide rail 11 is mounted on the bottom surface of the groove along the length of the cap beam 1 and is used to support the slidable slider 12. The slider 12 is slidably mounted on the guide rail 11 and is located on both sides of the guide rail 11 along the length of the guide rail 11. The guide rail 11 and the sliders 12 on both sides jointly serve as a guide and support. The movable plate 13 is mounted on the sliders 12 on both sides and can move along the length of the cap beam 1 under the guidance and support of the guide rail 11 and the sliders 12 on both sides. The first connecting rod 14 is rotatably mounted between the movable plates 13 on both sides and the first support plates 5 on both sides and can rotate relative to the movable plates 13 and the first support plates 5 on both sides. The second optical axis 15 is mounted on the bottom surface of the groove along the height direction of the cap beam 1 and is located between the movable plates 13 on both sides. It is used to support the rotatable second pivot arm 16. The second rotating arm 16 is rotatably mounted on the top of the second optical axis 15 and can rotate relative to the second optical axis 15. The second connecting rod 17 is rotatably mounted between the two ends of the second rotating arm 16 and the two side movable plates 13, and can rotate relative to the two ends of the second rotating arm 16 and the two side movable plates 13.

[0044] In the disclosed embodiment, when the second support shaft rotates, it drives the second rotating arm 16 to rotate. Then, under the pull or push of the second connecting rods 17 on both sides, and the guiding support of the guide rails 11 and the sliders 12 on both sides, the movable plates 13 on both sides can move toward or in opposite directions. Then, under the pull or push of the first connecting rods 14 on both sides, the second support plates 7 on both sides can be synchronously lowered or raised. Therefore, when the top surface of one side of the web beam 2 is subjected to overload pressure, pressing down the second support plate 7 on the same side, driven by the first optical axis 6 on the same side, after the first support plate 5 on the same side moves downward, the first support plate 5 on the other side will also move downward synchronously. When the support plate on the other side moves downward, the hydraulic oil in the rodless chamber of the first hydraulic cylinder 4 on the other side can enter the rodless chamber of the second hydraulic cylinder 10 on the other side, and the hydraulic oil in the rod chamber of the second hydraulic cylinder 10 on the other side can enter the rod chamber of the first hydraulic cylinder 4 on the other side, thereby causing the movable end of the second hydraulic cylinder 10 on the other side to extend. Then, supported by the first support 8 on the other side, the first rotating arm 9 on the other side can deflect toward the web beam 2, thereby increasing the support force on the other side of the web beam 2. Therefore, when one side of the top surface of the web beam 2 is subjected to overload pressure, both sides of the web beam 2 can be stably supported. This further enhances the bridge's lateral anti-overturning performance and improves the beam's ability to prevent it from falling off.

[0045] Optionally, combined Figure 1 、 Figure 4 、 Figure 5 and Figure 6 As shown, the second support 18 is further included. The second support 18 is rotatably mounted on both ends of the first connecting rod 14 on both sides, and is respectively connected to the moving plates 13 on both sides and the first supporting plates 5 on both sides.

[0046] In the embodiment of the present disclosure, the second support 18 is respectively connected to the movable plates 13 on both sides and the first support plates 5 on both sides, and is used to support and install the rotatable first connecting rods 14 on both sides, so as to facilitate the installation or disassembly of the first connecting rods 14 on both sides.

[0047] Optionally, combined Figure 1 、 Figure 2 and Figure 5 As shown, it also includes a pin 19. The pin 19 is rotatably mounted on both ends of the second connecting rod 17 on both sides, and is respectively connected to the two ends of the second rotating arm 16 and the moving plates 13 on both sides.

[0048] In the disclosed embodiment, the pins 19 are respectively connected to both ends of the second rotating arm 16 and the two side movable plates 13, and are respectively used to support and install the rotatable second connecting rods 17 on both sides, so as to facilitate the installation or disassembly of the second connecting rods 17 on both sides.

[0049] Optionally, combined Figure 1 、 Figure 4and Figure 6 As shown, the optical fiber 12 further includes a seat bearing 20 . The seat bearing 20 is sleeved on the second optical axis 15 and mounted on the second rotating arm 16 .

[0050] In the disclosed embodiment, a bearing block 20 is further included, which is mounted on the second optical axis 15 and installed on the second rotating arm 16. The bearing block 20 is used to reduce the friction between the second rotating axis and the second rotating arm 16 and improve the precision of the second rotating arm 16 when rotating relative to the second rotating axis.

[0051] Optionally, combined Figure 1 、 Figure 3 and Figure 7 As shown, it also includes a third support 21, a third optical axis 22, a moving block 23, a cam bearing 24 and a clamping block 25. The third support 21 is installed on the top surface of the sealing plate 3 and is located on both sides of the sealing plate 3 along the length direction of the cap beam 1. The first supports 8 on both sides are located between the third supports 21 on both sides, and the second supports 18 on both sides are respectively used to support and install multiple slidable second optical axes 15. The third optical axes 22 are slidably arranged on the third supports 21 on both sides along the length direction of the cap beam 1, and are evenly distributed on the third supports 21 on both sides. The multiple third optical axes 22 on both sides are used to serve as guide supports. The moving blocks 23 are respectively installed at the opposite ends of the multiple third optical axes 22 on both sides. Under the guiding support of the multiple third optical axes 22 on both sides, they can move along the length direction of the cap beam 1. The sides of the moving blocks 23 on both sides are provided with sliding grooves, and the sliding grooves on both sides are used to serve as limiters. Cam bearings 24 are mounted on one end of the first rotating arms 9 on either side, located outside the groove, and are located inside the slide grooves on either side, respectively, to reduce friction and enable the movable blocks 23 on either side to move with the rotation of the first rotating arms 9. Clamping blocks 25 are mounted on opposite sides of the movable blocks 23 on either side, and the clamping blocks 25 on either side abut against the two side surfaces of the web beam 2.

[0052] In the disclosed embodiment, when both first rotating arms 9 deflect toward the web beam 2, the movable blocks 23 on either side, guided and supported by the multiple third optical axes 22 on either side, and driven by the cam bearings 24 on either side, can move toward each other, ultimately allowing the clamping blocks 25 on either side to support the two side surfaces of the web beam 2. By using the two clamping blocks 25 to abut against the two side surfaces of the web beam 2, the contact area between the two sides and the web beam 2 is increased, thereby enhancing the contact effect on the web beam 2.

[0053] Optionally, combined Figure 1 、 Figure 3 、 Figure 7 and Figure 8 As shown, the first linear bearing 26 is further included. The first linear bearing 26 is respectively mounted on the third optical axes 22 on both sides and is also mounted on the third supports 21 on both sides.

[0054] In the disclosed embodiment, further included are first linear bearings 26 that are respectively fitted over the plurality of third optical axes 22 on either side and mounted on the third supports 21 on either side. The plurality of first linear bearings 26 on either side are used to reduce friction between the plurality of third optical axes 22 on either side and the third supports 21 on either side, and to improve the sliding precision of the plurality of third optical axes 22 relative to the third supports 21 on either side.

[0055] Optionally, combined Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the second linear bearings 27 are also included. The second linear bearings 27 are respectively mounted on the first optical axes 6 on both sides and are all installed on the sealing plate 3.

[0056] In the disclosed embodiment, second linear bearings 27 are further included, each of which is fitted over the plurality of first optical shafts 6 on both sides and mounted on the sealing plate 3. The plurality of second linear bearings 27 on both sides are used to reduce the friction between the plurality of first optical shafts 6 on both sides and the sealing plate 3, and to improve the sliding precision of the plurality of first optical shafts 6 on both sides relative to the sealing plate 3.

[0057] Optionally, combined Figure 1 and Figure 2 As shown, the system further includes a fourth support 28 and a fifth support 29. The fourth support 28 is connected to the movable end of the second hydraulic cylinder 10 on either side and is rotatably mounted to one end of the first rotating arm 9 on either side, located within the groove. The fifth support 29 is rotatably mounted to the rear end of the second hydraulic cylinder 10 on either side and is mounted to the bottom surface of the groove.

[0058] In the disclosed embodiment, the fourth supports 28 on both sides are used to realize the rotatable installation between the second hydraulic cylinders 10 on both sides and the first rotating arms 9 on both sides, and the fifth supports 29 on both sides are used to realize the rotatable installation between the second hydraulic cylinders 10 on both sides and the bottom surface of the groove.
