Description

Technical Field

[0001] This invention relates to the field of reinforcement devices, and more specifically, to a bridge reinforcement device and reinforcement method. Background Technology

[0002] Bridge reinforcement generally refers to restoring or improving the load-bearing capacity of existing bridges by strengthening components and improving structural performance, so as to extend their service life and meet the requirements of modern transportation.

[0003] Existing equipment for bridge reinforcement requires pre-embedded installation, which can easily damage the strength of the bridge structure itself. Furthermore, the support device as a whole cannot adapt well to the deformation of the bridge structure, which can easily lead to the deformation of the device as a whole, thereby affecting the strength of the reinforcement. Therefore, a bridge reinforcement device and reinforcement method are provided. Summary of the Invention

The second mounting plate is integrally mounted on the other end of the main support, and the first buffer frame is connected to the outer side of the second mounting plate. A sliding groove is formed on the inner side of the first buffer frame.

[0007] The buffer assembly includes shock-absorbing pads, guide rails, a crossbar, a buffer pad, a spring, a second buffer frame, an auxiliary support, and a gasket. The bottom of the abutment is fixedly installed with shock-absorbing pads. Guide rails are slidably connected to both sides of the first buffer frame.

[0009] Preferably, the main support forms a sliding structure between the first mounting plate and the mounting groove, and the main support also forms a sliding structure between the second mounting plate and the sliding groove. The main support, the abutment plate, and the connecting frame are arranged in a triangular configuration.

[0010] Preferably, the first buffer frame forms a sliding structure between the guide rail and the crossbar, the first buffer frame and the second buffer frame are symmetrically arranged relative to each other about the central axis of the guide rail, and the second buffer frame forms a telescopic structure between the second buffer frame and the first buffer frame through a spring.

[0011] Preferably, the auxiliary support forms an engaging structure with the abutment through the second buffer frame, and the auxiliary support and the main support are arranged in a Y-shape.

[0012] Preferably, the transmission component forms a rotating structure with the fixed frame via the rotating rod, and the slide rod forms a transmission structure with the transmission component via the linkage rod. The gears are arranged at equal intervals along the internal vertical direction of the fixed frame and are meshed together.

[0013] Preferably, the slide rail forms an engaging structure with the fixed frame through the slide rod, and the slide rod is symmetrically arranged about the central axis of the main support rod.

[0014] Preferably, the auxiliary mechanism includes a connecting shaft, a support leg, and a limiting support platform. The support leg is rotatably connected to the outside of the connecting shaft, and the limiting support platform is provided on the outside of the support leg.

[0015] Preferably, the support leg forms a rotating structure with the ring sleeve via a connecting shaft, and the support leg forms a locking structure with the ring sleeve via a limiting load-bearing platform. The ring sleeve forms a detachable structure with the main support rod via a positioning bolt.

[0016] This invention provides a bridge reinforcement device and method, the method comprising the following steps:

[0017] S1. The control motor drives the gear and rotating rod to rotate, which in turn drives the transmission component and linkage rod through the rotating rod. The linkage rod moves up and down with the rotation of the transmission component, thereby driving the slide rod at the end to slide along the inside of the limiting groove. This can stably control the slide rod and the slide rail to separate from each other. At the same time, the gear can drive other gears on both sides to ensure that multiple sets of equipment can control the internal slide rod synchronously. At this time, the position of the main support rod and the connecting frame can be adjusted. After the connecting frame is adjusted to the appropriate length, the control motor drives the slide rod to extend outward again, so that the slide rod and the slide rail can be inserted into each other to complete the adjustment.

[0018] S2. Next, after the top of the abutment plate contacts the bottom of the bridge, the bottom shock-absorbing pads are compressed. The shock-absorbing pads can provide a certain buffer to ensure that the abutment plate does not directly interact with the connecting frame and prevent deformation. At the same time, the main brackets on both sides can be installed laterally, allowing the first mounting plate and the mounting groove to slide against each other, and the second mounting plate and the sliding groove to slide against each other. The auxiliary brackets and the second buffer frame are also installed simultaneously. Flexible disassembly and assembly facilitates transportation. When under pressure, the second buffer frame and the first buffer frame on both sides slide relative to each other along the guide rail and pull the middle spring to distribute the force. At the same time, the buffer pads and crossbars at both ends can bear the force and limit the movement to ensure stability. The overall Y-shaped design ensures stable support, and the symmetrical design ensures uniform force distribution and better reinforcement effect.

[0019] S3. Finally, the bottom of the main support rod can be inserted into the middle of the soil for installation. The outer ring at the bottom of the main support rod can be adjusted to the appropriate height as needed and fixed with positioning bolts. The opening angle of the support leg can be adjusted according to the height of the ring and the limiting support platform, so that the limiting support platform blocks the angle of the support leg to complete the support assistance. After opening, the top of the limiting support platform is filled with soil to ensure that the support platform is further stabilized by the weight of the soil, which helps to ensure the overall installation stability.

[0020] The present invention provides a bridge reinforcement device and method, which, when used, have the following advantages:

[0021] Beneficial effects:

[0022] 1. The reinforcement device provided by the present invention provides overall support through the top abutment plate, the lower connecting frame, and the main support rod. When the abutment plate contacts the bridge ground, it can be pressed down according to the inclination of the bridge ground. The abutment plate with a certain degree of mobility can adjust its angle through the bottom shock-absorbing pad and the support mechanism on both sides, so as to better ensure the overall fit and effectively absorb and disperse the vibration of the bridge body. The multiple sets of supports and the Y-shaped arrangement can maximize the support effect.

[0023] 2. By incorporating a buffer assembly, both the main support and auxiliary support ends are equipped with pads, ensuring overall connection stability while allowing for a certain range of motion. The pads are integrated with the main support and the first mounting plate, and the other side engages with the support equipment. Compared to directly integrated support equipment, this provides a better range of motion for the entire device, better adapting to support operations. The top spring and crossbar ensure the tension distance and range of motion, acting as a limiter. This ensures better fit to the bottom of the bridge while also absorbing and dispersing vibrations through the range of motion, springs, and buffer pads, thus guaranteeing stable operation.

[0024] 3. The inclusion of sliding rods allows for tight installation of the equipment, and also enables overall height adjustment. The height can be adjusted by changing the position between the lower connecting frame and the main support rod. The rotation of the gears controlled by the external motor drives the internal sliding rods to move back and forth. Multiple sets of sliding rods limit the movement of the lower connecting frame and the main support rod, ensuring flexible adjustment while maintaining the stability of the overall connection and better adapting to the installation and use of bridge bodies of different specifications.

[0025] 4. With the auxiliary mechanism in place, when the equipment is erected, the bottom of the main support rod can contact the soil or water, and the soil can be filled on the top of the limiting support platform to further pressurize it, so as to ensure the stability of the installation. Before filling the soil, the opening and closing angle of the support legs can be controlled to provide auxiliary support on both sides, so as to ensure that the bottom of the whole can stand stably. At the same time, the soil is filled and compacted to fix it, further ensuring the connection of the overall support, which is conducive to the use of the whole and ensures the stability of the reinforcement.

[0036] Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0037] For examples, please refer to Figure 1-5 .

[0038] like Figure 1-5As shown, a bridge reinforcement device and reinforcement method include a support plate 1 and a support mechanism at the bottom of the support plate 1. The support mechanism includes an installation component and a buffer component.

[0039] The mounting components include a connecting frame 3, a main support 4, a first mounting plate 5, a mounting groove 6, a second mounting plate 7, a first buffer frame 8, and a sliding groove 9. The connecting frame 3 is located below the abutment plate 1. The main support 4 is movably mounted on the side of the connecting frame 3. The first mounting plate 5 is integrally mounted on one end of the main support 4. The outer side of the first mounting plate 5 is slidably connected to the inside of the mounting groove 6. The second mounting plate 7 is integrally mounted on the other end of the main support 4. The first buffer frame 8 is connected to the outer side of the second mounting plate 7. The sliding groove 9 is opened on the inner side of the first buffer frame 8.

[0040] The buffer assembly includes a shock-absorbing pad 2, a guide rail 10, a crossbar 11, a buffer pad 12, a spring 13, a second buffer frame 14, an auxiliary support 15, and a gasket 16. The shock-absorbing pad 2 is fixedly installed at the bottom of the abutment 1. The guide rail 10 is slidably connected to both sides of the first buffer frame 8. The end of the first buffer frame 8 is slidably connected to the inside of the crossbar 11. The buffer pad 12 is fixedly installed on the inner wall of the crossbar 11. The other end of the first buffer frame 8 is connected to the spring 13. The end of the spring 13 is connected to the second buffer frame 14. The auxiliary support 15 is movably connected to the inner side of the second buffer frame 14, and the gasket 16 is engaged at the end of the auxiliary support 15.

[0041] Furthermore, a main support rod 17 is slidably installed inside the connecting frame 3, a fixed frame 18 is fixedly installed on the outside of the main support rod 17, a motor 19 is stably installed on the outside of the fixed frame 18, a gear 20 is connected to the output end of the motor 19, a rotating rod 21 is connected to the middle of the gear 20, a transmission component 22 is integrally provided at the end of the rotating rod 21, and a linkage rod 23 is rotatably connected to the side of the transmission component 22, a rotating shaft 24 is rotatably connected to the end of the linkage rod 23, a sliding rod 25 is stably connected to the side of the rotating shaft 24, a limit groove 26 is slidably connected to the outside of the sliding rod 25, a slide rail 27 is provided in the middle of the main support rod 17, a ring 28 is provided through the periphery of the main support rod 17, a positioning bolt 29 is provided in the middle of the ring 28, and auxiliary mechanisms 30 are symmetrically provided on both sides of the ring 28.

[0042] Furthermore, the main support 4 forms a sliding structure between the first mounting plate 5 and the mounting groove 6, and the main support 4 also forms a sliding structure between the second mounting plate 7 and the sliding groove 9. The main support 4, the abutment plate 1, and the connecting frame 3 are arranged in a triangle. Both the main support 4 and the auxiliary support 15 are provided with gaskets 16 at their ends to ensure overall connection stability while allowing for a certain range of motion. The gaskets 16 are integrated with the main support 4 and the first mounting plate 5 respectively, and the other side is engaged with the support equipment. Compared with the directly integrated support equipment, this provides a better range of motion for the overall equipment.

[0043] Furthermore, the first buffer frame 8 forms a sliding structure between the guide rail 10 and the crossbar 11. The first buffer frame 8 and the second buffer frame 14 are symmetrically arranged relative structures about the central axis of the guide rail 10. The second buffer frame 14 forms a telescopic structure between the first buffer frame 8 and the spring 13. The arrangement of the top spring 13 and the crossbar 11 can ensure the stretching distance and range of motion, playing a limiting role. This ensures better fit to the bottom of the bridge, while also ensuring the absorption and dispersion of vibration through a certain range of motion, the spring 13, and the buffer pad 12, thus better ensuring stable use.

[0044] Furthermore, the auxiliary support 15 forms an engaging structure with the abutment plate 1 through the second buffer frame 14, and the auxiliary support 15 and the main support 4 are arranged in a Y-shape, which can effectively absorb and disperse the vibration of the bridge body. The multiple sets of supports and the Y-shaped arrangement can ensure the support effect to the greatest extent.

[0045] Furthermore, the transmission component 22 forms a rotating structure with the fixed frame 18 through the rotating rod 21, and the slide rod 25 forms a transmission structure with the transmission component 22 through the linkage rod 23. The gears 20 are evenly spaced and meshed along the internal vertical direction of the fixed frame 18, ensuring that the lower connecting frame 3 and the main support rod 17 can be limited by multiple sets of slide rods 25. This ensures flexible adjustment while maintaining the stability of the overall connection and engagement, and better adapts to the installation and use of bridge bodies of different specifications.

[0046] Furthermore, the slide rail 27 forms an engaging structure with the fixed frame 18 through the slide rod 25, and the slide rod 25 is symmetrically arranged about the central axis of the main support rod 17, so the height can be adjusted by adjusting the position between the lower connecting frame 3 and the main support rod 17.

[0047] Furthermore, the auxiliary mechanism 30 includes a connecting shaft 3001, a support leg 3002, and a limiting load-bearing platform 3003. The support leg 3002 is rotatably connected to the outside of the connecting shaft 3001, and the limiting load-bearing platform 3003 is provided on the outside of the support leg 3002. The auxiliary support on both sides can be provided by controlling the opening and closing angle of the support leg 3002 to ensure that the bottom of the whole can stand stably. At the same time, it can be compacted and fixed with the backfill soil to further ensure the connection firmness of the overall support, facilitate the use of the whole, and ensure the stability of the reinforcement.

[0048] Furthermore, the support leg 3002 forms a rotating structure with the ring sleeve 28 via the connecting shaft 3001, and the support leg 3002 forms a locking structure with the ring sleeve 28 via the limiting load-bearing platform 3003. The ring sleeve 28 forms a detachable structure with the main support rod 17 via the positioning bolt 29. The bottom of the main support rod 17 can contact the soil or water, and the top of the limiting load-bearing platform 3003 can be further pressurized by filling soil to ensure the stability of the installation.

[0049] This solution also provides a bridge reinforcement device and method, the method including the following steps:

[0050] S1. First, the control motor 19 drives the gear 20 and the rotating rod 21 to rotate. The rotating rod 21 can transmit the transmission component 22 and the linkage rod 23, so that the linkage rod 23 moves up and down with the rotation of the transmission component 22. This drives the end slide rod 25 to slide along the inside of the limiting groove 26, which can stably control the slide rod 25 to separate from the slide rail 27. At the same time, the gear 20 can transmit the transmission to other gears 20 on both sides, ensuring that multiple sets of equipment can control the internal slide rod 25 synchronously. At this time, the main support rod 17 and the connecting frame 3 can be adjusted in position. After the connecting frame 3 is adjusted to a suitable length, the control motor 19 drives the slide rod 25 to extend outward again, so that the slide rod 25 and the slide rail 27 can be inserted into each other to complete the adjustment.

[0051] S2. Next, after the top of the abutment plate 1 contacts the bottom of the bridge, the bottom shock-absorbing pad 2 is compressed. The shock-absorbing pad 2 can provide a certain buffer to ensure that the abutment plate 1 does not directly interact with the connecting frame 3, thus preventing deformation. At the same time, the main bracket 4 can be installed laterally on both sides, allowing the first mounting plate 5 and the mounting groove 6 to slide relative to each other. Meanwhile, the second mounting plate 7 and the sliding groove 9 slide relative to each other. The auxiliary bracket 15 and the second buffer frame 14 are also installed simultaneously. Flexible disassembly and assembly facilitates transportation. When compressed, the second buffer frame 14 and the first buffer frame 8 on both sides slide relative to each other along the guide rail 10 and pull the middle spring 13 to disperse the force. At the same time, the buffer pads 12 and the crossbars 11 at both ends can bear the force and limit the movement, ensuring stability. The overall Y-shaped setting ensures stable support, and the symmetrical setting ensures uniform force distribution and better reinforcement effect.

[0052] S3. Finally, the bottom of the main support rod 17 can be inserted into the middle of the soil for installation. The outer ring 28 at the bottom of the main support rod 17 can be adjusted to a suitable height as needed and fixed by the positioning bolt 29. The opening angle of the support leg 3002 can be adjusted according to the height of the ring 28 and the limiting support platform 3003, so that the limiting support platform 3003 blocks the angle of the support leg 3002 to complete the support assistance. After opening, the top of the limiting support platform 3003 is further backfilled to ensure that the support platform is further stabilized by the weight of the soil, which is conducive to ensuring the overall installation stability.

[0053] Working principle: First, the control motor 19 drives the gear 20 and the rotating rod 21 to rotate. The rotating rod 21 drives the transmission component 22 and the linkage rod 23, causing the linkage rod 23 to move up and down following the rotation of the transmission component 22. This causes the end slide rod 25 to slide along the inside of the limiting groove 26, which can stably control the slide rod 25 to separate from the slide rail 27. At the same time, the gear 20 can drive the other gears 20 on both sides, ensuring that multiple sets of equipment can control the internal slide rod 25 synchronously. At this time, the position of the main support rod 17 and the connecting frame 3 can be adjusted. After the connecting frame 3 is adjusted to a suitable length, the control motor 19 drives the slide rod 25 to extend outward again, so that the slide rod 25 and the slide rail 27 can be inserted into each other to complete the adjustment.

[0054] Secondly, after the top of the abutment plate 1 contacts the bottom of the bridge, the bottom shock-absorbing pad 2 is compressed. The shock-absorbing pad 2 can provide a certain buffer to ensure that the abutment plate 1 does not directly interact with the connecting frame 3, thus preventing deformation. At the same time, the main bracket 4 can be installed laterally on both sides, allowing the first mounting plate 5 and the mounting groove 6 to slide relative to each other. Meanwhile, the second mounting plate 7 and the sliding groove 9 can slide relative to each other. The auxiliary bracket 15 and the second buffer frame 14 are also installed simultaneously, which facilitates flexible disassembly and assembly and transportation. When under pressure, the second buffer frame 14 and the first buffer frame 8 on both sides slide relative to each other along the guide rail 10 and pull the middle spring 13 to distribute the force. At the same time, the buffer pads 12 and the crossbars 11 at both ends can bear the force and limit the movement, ensuring stability. The overall Y-shaped design ensures stable support, and the symmetrical design ensures uniform force distribution and better reinforcement effect.

[0055] Finally, the bottom of the main support rod 17 can be inserted into the middle of the soil for installation. The outer ring 28 at the bottom of the main support rod 17 can be adjusted to a suitable height as needed and fixed by the positioning bolt 29. The opening angle of the support leg 3002 can be adjusted according to the height of the ring 28 and the limiting support platform 3003, so that the limiting support platform 3003 blocks the angle of the support leg 3002 to complete the support assistance. After opening, the top of the limiting support platform 3003 is further backfilled to ensure that the support platform is further stabilized by the weight of the soil, which is conducive to ensuring the overall installation stability.

After the connecting frame is adjusted to the appropriate length, the control motor drives the slide rod to extend outward again, so that the slide rod and the slide rail can be inserted into each other to complete the adjustment. S2. Next, after the top of the abutment plate contacts the bottom of the bridge, the bottom shock-absorbing pads are compressed. The shock-absorbing pads can provide a certain buffer to ensure that the abutment plate does not directly interact with the connecting frame and prevent deformation. At the same time, the main brackets on both sides can be installed laterally, allowing the first mounting plate and the mounting groove to slide against each other, and the second mounting plate and the sliding groove to slide against each other. The auxiliary brackets and the second buffer frame are also installed simultaneously. Flexible disassembly and assembly facilitates transportation. When under pressure, the second buffer frame and the first buffer frame on both sides slide relative to each other along the guide rail and pull the middle spring to distribute the force. At the same time, the buffer pads and crossbars at both ends can bear the force and limit the movement to ensure stability. The overall Y-shaped design ensures stable support, and the symmetrical design ensures uniform force distribution and better reinforcement effect. S3. Finally, the bottom of the main support rod is inserted into the middle of the soil for installation. The outer ring at the bottom of the main support rod is adjusted to the appropriate height as needed and fixed with positioning bolts. The opening angle of the support leg can be adjusted according to the height of the ring and the limiting support platform. The limiting support platform blocks the angle of the support leg to complete the support assistance. After opening, the top of the limiting support platform is filled with soil to ensure that the support platform is further stabilized by the weight of the soil, which helps to ensure the overall installation stability.
