Description

Technical Field

[0001] The present invention relates to the field of bridge engineering, and in particular to a tensile support adaptable to bending and torsional deformation of curved bridges. Background Art

[0002] Curved bridges can save space by changing the direction of traffic routes. They are important transportation hubs for interchanges and are widely used in urban overpasses. Compared to straight bridges, curved bridges experience significantly different forces during construction and operation. This is especially true for bridges with a small radius of curvature. The weight of the inner and outer ring beams is inconsistent, with the outer side weighing more than the inner side. The prestressed reinforcement arrangement of the bridge floor generates a torque along the main beam, with the overall effect of causing the beam to flip outward. These factors will intensify the combined bending and torsion effects of curved bridges under constant loads, easily causing the beam to twist outward, resulting in the loss of the inner supports of the beam, affecting the service life of the bridge supports, and in severe cases, even leading to bridge collapse. The provision of supports with pull-out resistance is an effective means of solving the above problems.

[0003] Existing tensile bearings are mostly rigid tensile bearings with spherical joints. Because these bearings use a fixed connection between the beam and the pier, the beam can be subjected to excessive tension and damage due to the combined effects of bending and torsion. This has led to the development of tensile bearings with replaceable connectors. The tensile bearing disclosed in Publication No. CN215758505U utilizes flexible tensile connectors connected to upper and lower support plates, which are fixedly connected to the beam and pier, respectively. When the inner side of a curved bridge deflects upward, the flexible tensile connectors pull on the upper and lower support plates to provide a pullout force. However, due to connector strength issues, these bearings can also be damaged by damage. Compared to traditional tensile bearings, this bearing allows for replacement of the connectors after damage, reducing replacement costs. However, manual replacement is inefficient, resulting in untimely replacements, and the problem of bearing damage due to combined bending and torsion is still unresolved. Therefore, the invention of a tensile bearing that can prevent bearing damage caused by bending and torsion deformation of curved bridges and provide tension data feedback is an urgent problem for those skilled in the art.

[0007] The support assembly includes a second seat plate and a hollow shell located on the second seat plate, wherein a baffle is further provided inside the shell, the baffle being fixed to the inner wall of the shell and having a certain distance from the upper and lower surfaces of the shell;

[0008] The shell and the baffle are respectively provided with a first slide groove and a second slide groove, and the force transmission column can slide up and down in the first slide groove and the second slide groove. The first seat plate is located above the shell, and the partition is provided inside the shell and below the baffle.

[0009] The pressure plate is arranged above the baffle, and a plurality of vertical wedges are provided on the lower surface of the pressure plate. The baffle is provided with a transverse wedge corresponding to each vertical wedge. The contact surface of each vertical wedge and the corresponding transverse wedge forms a certain angle with the horizontal direction. The area between the pressure plate and the shell is filled with pre-pressed rubber.

[0010] The edge of the partition is also provided with an annular first sealing ring, which abuts against the inner wall of the shell. The upper and lower chambers of the partition are connected through a two-way resistance valve, and the two-way resistance valve is arranged through the upper and lower surfaces of the partition;

[0012] Optionally, the two-way resistance valve includes a valve top seat, a valve core, a valve base and a spring, the valve core is elastically connected to the valve top seat and the valve base through the spring, and the valve top seat and the valve base are connected to the upper and lower cavities of the partition through the corresponding first through groove and second through groove;

[0013] The first through groove and the second through groove are through-connected on the corresponding valve top seat and valve base.

[0014] Optionally, the upper and lower surfaces of the valve core are provided with a first flow-blocking structure and a second flow-blocking structure that match the corresponding first through-groove and second through-groove, and the maximum cross-sections of the first flow-blocking structure and the second flow-blocking structure are larger than the maximum cross-sections of the corresponding first through-groove and the second through-groove.

[0015] Optionally, the first flow-blocking structure is conical, and the second flow-blocking structure is inverted conical.

[0016] Optionally, a first groove capable of accommodating each transverse wedge is provided in the baffle, and each first groove is connected to the second sliding groove.

[0023] Beneficial effects:

[0024] 1. The combination of the moving assembly, the supporting assembly and the pressure plate ensures the sealing of the tensile support. The tensile support is stretched to adapt to the bending and torsional deformation of the curved bridge, thereby reducing the tensile force on the support and preventing it from being damaged.

[0025] 2. The setting of the two-way resistance valve, when the vehicle load is applied, uses the internal hydraulic oil to drive the valve core to block the valve to prevent the movement of the moving component, so that the support can withstand pressure or tension, and the flow section in the valve can allow a small amount of liquid to flow before it is reduced to zero to achieve buffering;

[0026] 3. The setting of the pre-stressed rubber above the pressure plate is conducive to the pressure plate generating a downward force, and the interaction between the vertical wedges and the horizontal wedges changes the direction of force transmission, thereby improving the sealing effect of the sealing ring connected to one end of the horizontal wedge. The pre-stressed rubber also effectively prevents the sealing ring from direct contact with air;

[0027] 4. The matching settings between various components, such as the matching of the force transmission column with the first and second slide slots, and the matching of the partition with the inner size of the shell, improve the sealing and tensile resistance effects;

[0028] 5. The force transmission column is rotatably connected to the first seat plate, so that the tensile support can withstand a certain degree of rotational deformation while bearing tension and pressure;

[0029] 6. The setting of the intelligent tension monitoring system can realize real-time monitoring of the tension borne by the support and feed it back to the monitoring center, so as to achieve real-time monitoring of the tension of the support. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] See also Figures 1 to 8 The present invention provides an embodiment of a tensile support adapted to the bending and torsional deformation of a curved bridge, wherein: Figure 1 As shown, the tensile support adapted to the bending and torsional deformation of a curved bridge includes a moving component 1, a supporting component 2 matched with the moving component 1, a pressure plate 3 arranged in the supporting component 2, and a tension intelligent monitoring system 4.

[0048] like Figure 1-2 As shown, the moving assembly 1 includes a first seat plate 11, a partition plate 13, and a force transmission column 12, one end of which is connected to the first seat plate 11 and the other end of which passes through the partition plate 13. Preferably, the contact area between the partition plate 13 and the force transmission column 12 is fixedly connected. Figure 3As shown, the support assembly 2 includes a second seat plate 22 and a hollow shell 21 located on the second seat plate 22. A baffle 23 is further provided inside the shell 21. The baffle 23 is fixed to the inner wall of the shell 21 and has a certain distance from the upper and lower surfaces of the shell 21. The shell 21 and the baffle 23 are respectively provided with a through first slide groove 211 and a through second slide groove 231. The first slide groove 211 is set through the upper surface of the shell 21. The first slide groove 211 and the second slide groove 231 are respectively in contact with the outer surface of the force transmission column 12, and the force transmission column 12 can slide up and down in the first slide groove 211 and the second slide groove 231. The first seat plate 11 is located above the shell 21, and the partition 13 is provided inside the shell 21 and below the baffle 23, so that the moving assembly 1 can slide up and down in the hollow shell 21. In addition, as Figure 2 As shown, a rubber pad 121 is further provided at one end of the force transmission column 12 passing through the partition 13. The rubber pad 121 is provided to prevent the force transmission column 12 from contacting with the upper surface of the second seat plate 22 and causing loss during the process of sliding up and down in the first slide groove 211 and the second slide groove 231, and also to provide a certain buffering effect.

[0049] Furthermore, if Figure 2 As shown, the edge of the partition 13 is also provided with an annular first sealing ring 131, which abuts against the inner wall of the shell 21, thereby sealing the upper and lower cavities of the partition 13, and the upper and lower cavities of the partition 13 are connected through a two-way resistance valve 14, and the two-way resistance valve 14 is arranged through the upper and lower surfaces of the partition 13. Generally, the upper and lower ends of the two-way resistance valve 14 are aligned with the upper and lower surfaces of the partition 13.

[0050] In this embodiment, hydraulic oil can be filled in the upper and lower chambers of the partition 13, and the hydraulic oil in the upper and lower chambers of the partition 13 can flow through the two-way resistance valve 14. At the same time, the first seat plate 11 and the second seat plate 22 are respectively connected to the main beam and the bridge pier through corresponding anchor rods. When the inner side of the curved bridge moves upward due to combined bending and torsion deformation, it can drive the moving assembly 1 of the tensile support to move together with the main beam, that is, drive the first seat plate 11, the force transmission column 12, and the partition 13 to move upward, and start to transmit tension when the partition 13 moves upward and contacts the baffle 23. The force transmission path is that the pulling force passes through the anchor rod connected to the main beam, the first seat plate 11, the force transmission column 12, the partition 13, the baffle 23, the shell 21, the second seat plate 22, the anchor rod connected to the bridge pier, and finally reaches the foundation through the bridge pier. While the force transmission column 12 drives the partition 13 to move upward, the hydraulic oil above the partition 13 flows to the bottom of the partition 13 through the two-way resistance valve 14, and the first sealing ring 131 located on the edge of the partition 13 ensures the independence and sealing of the upper and lower spaces of the partition 13.

[0051] Furthermore, if Figure 4-5As shown, a plurality of vertical wedges 31 are protruding from the lower surface of the pressure plate 3, wherein the pressure plate 3 is arranged above the baffle 23, and the baffle 23 is provided with a horizontal wedge 232 corresponding to each vertical wedge 31, and the contact surface between each vertical wedge 31 and the corresponding horizontal wedge 232 forms a certain angle with the horizontal direction, and the angle is 15-75 degrees. Preferably, the angle is 45 degrees, and the area between the pressure plate 3 and the shell 21 is filled with pre-stressed rubber.

[0052] Furthermore, the baffle 23 is provided with a first groove for accommodating each transverse wedge 232. Each first groove is connected to a second chute 231. A square second sealing ring 233 is provided on the surface of the second chute 231. The inner surface of the second sealing ring 233 abuts the outer surface of the force transmission column 12, and the outer portion of the second sealing ring 233 is fixedly connected to one end of each transverse wedge 232. Furthermore, each transverse wedge 233 can slide within a corresponding first groove in the baffle 23. Preferably, the number of the first grooves is set to two or more.

[0053] Specifically, generally, pre-stressed rubber is filled between the upper portion of the pressure plate 3 and the outer shell 21, and the pre-stressed rubber adheres to the outer surface of the force transmission column 12, thereby enabling the force transmission column 12 to have a certain sealing effect during the vertical sliding process. Among them, the pressure plate 3 can generate a downward movement tendency under the push of the pre-stressed rubber. At this time, the pressure plate 3 will push the vertical wedge 31 to generate a downward movement tendency, and the horizontal wedge 232 can slide in the baffle 23. At this time, the horizontal wedge 232 will generate a tendency to move toward the center of the support, that is, the horizontal wedge 232 will squeeze the second sealing ring 233. Similarly, the same wedge is arranged on the adjacent edge of this wedge to squeeze the second sealing ring 233 in the other direction. Therefore, the second sealing ring 233 is tightly attached to the force transmission column 12 and the baffle 23, so that the sealing effect of the cavity above the partition 13 is improved. In this embodiment, the force transmission column 12 is set as a quadrangular prism, and then the number of first grooves for accommodating the horizontal wedge 232 is set to two. In addition, the compression rubber above the pressure plate 3 also fits the force transmission column 12, which can prevent the second sealing ring 233 from directly contacting the air, thereby avoiding oxidation of the second sealing ring.

[0054] Furthermore, if Figure 7As shown, the two-way resistance valve 14 includes a valve top seat 141, a valve core 142, a valve base 143 and a spring 144. The valve core 142 is elastically connected to the valve top seat 141 and the valve base 143 through the spring 144. The valve top seat 141 and the valve base 143 are connected to the upper and lower chambers of the partition 13 through the corresponding first through groove 1411 and the second through groove 1431, thereby realizing the flow of hydraulic oil in the upper and lower chambers of the partition 13. Among them, the first through groove 1411 and the second through groove 1431 are arranged on the corresponding valve top seat 141 and valve base 143, and the maximum cross-sections of the first through groove 1411 and the second through groove 1431 are smaller than the cross-section of the valve core 142, so that the valve core 142 can contact with the valve top seat 141 or the valve base 143 under the action of the spring 144, and the valve core 142 can block the first through groove 1411 or the second through groove 1431, thereby stopping the flow of hydraulic oil between the upper and lower chambers of the partition 13, and enabling the support to withstand the tension or pressure caused by the vehicle load.

[0055] Furthermore, the upper and lower surfaces of the valve core 142 are provided with a first flow-blocking structure 1421 and a second flow-blocking structure 1422 that match the corresponding first through-groove 1411 and the second through-groove 1431. The maximum cross-sections of the first flow-blocking structure 1421 and the second flow-blocking structure 1422 are larger than the maximum cross-sections of the corresponding first through-groove 1411 and the second through-groove 1431. Specifically, the upper opening of the first through-groove 1411 is smaller than the lower opening, and the second through-groove 1431 is arranged in a mirror-symmetrical manner with the first through-groove 1411. During the up and down movement of the valve core 142, the flow cross-sections of the first through-groove 1411 and the second through-groove 1431 will change accordingly based on the corresponding extension of the first flow-blocking structure 1421 and the second flow-blocking structure 1422. The specific cross-sectional views AA and BB are as follows: Figure 8 shown.

[0056] In this embodiment, compared with the bending and torsional deformation of the curved bridge caused by the constant load, the deformation of the main beam caused by the vehicle load is instantaneous. When a vehicle passes on the inner side of the curved bridge, the movable component 1 tends to move downward rapidly, and the hydraulic oil below the partition 13 is squeezed and flows rapidly to the top of the partition 13. The valve core 142 in the two-way resistance valve 14 is driven by the hydraulic oil to move upward, and then the first flow-blocking structure 1421 gradually extends into the first through groove 1411, and the AA cross-sectional area (shaded part) is reduced and smaller than the BB cross-sectional area, until the valve core 142 contacts the valve top seat 141, that is, the flow section AA is completely closed, and the liquid flow is blocked. This process prevents the partition 13 from moving downward rapidly and thus prevents the movable component 1 from moving downward rapidly, making the movable component 1 relatively stable and ensuring the pressure-bearing performance of the support under the action of vehicle load. Among them, AA is the actual flow cross-section, which determines the pressure that the support can withstand. During the upward movement of the valve core 142, the reaction force of the spring 144 gradually increases. When the ratio of the tension generated by the spring 144 to the pressure that the support needs to withstand is equal to the ratio of the area of ​​the flow cross-section AA to the area of ​​the partition 13, the support can withstand the resulting pressure. Or, as described above, when the valve core 142 contacts the valve top seat 141, the flow cross-section AA is completely closed, and when the flow of liquid is blocked, the support can withstand even greater pressure. When a vehicle passes on the outside of the curved bridge, the movable assembly 1 tends to move upward rapidly, that is, the partition 13 tends to move upward rapidly. The hydraulic oil above the partition 13 is squeezed and tends to flow rapidly to the bottom of the partition 13. The working principle is exactly the opposite of when a vehicle passes on the inside of the curved bridge. At this time, BB is the actual flow cross-section, which prevents the partition 13 from moving upward rapidly, thereby preventing the movable assembly 1 from moving upward rapidly, ensuring the tensile strength of the support under the action of vehicle load.

[0057] Furthermore, the first flow-blocking structure 1421 is conical, and the second flow-blocking structure 1422 is inverted conical.

[0058] Further, if Figure 6 As shown, the force transmission column 12 is rotatably connected to the first seat plate 1, and a second groove is provided on the side of the first seat plate 1 close to the force transmission column 12, so that the end of the force transmission column 12 is embedded in the second groove. Preferably, the bottom of the second groove is arc-shaped, and the end surface of the force transmission column 12 is also arc-shaped.

[0059] Furthermore, an annular protrusion is provided on the side of the second groove, and the annular protrusion and the bottom of the second groove form an area that can accommodate the end of the force transmission column 12, and a rubber ring 111 is provided on the surface of the annular protrusion to prevent the end of the force transmission column 12 from rotational wear.

[0060] Further, if Figure 9As shown, it also includes a tension intelligent monitoring system 4, which includes a closed circuit formed by a conductive structure 41, an ammeter 42, a power supply 43, and a wire 44, and a monitoring center 45 communicatively connected to the ammeter 42; the wire 44 is used to connect the conductive structure 41, the ammeter 42, and the power supply 43 in series.

[0061] Specifically, if Figure 1 As shown, the conductive structure 41 is arranged on the lower surface of the baffle 23, and the ammeter 42, power supply 43 and wire 44 are all located in the housing 21. At the same time, the conductive structure 41 adopts intelligent pressure-sensitive material.

[0062] Furthermore, the intelligent pressure-sensitive material is composed of a thermoplastic elastomer, a polyolefin resin, conductive carbon black and a polyolefin film adsorbed with carbon black particles, wherein the polyolefin film is located on the upper and lower surfaces of the pressure-sensitive material and is connected to the two levels of the circuit through a wire 44. The thermoplastic elastomer acts as a material skeleton and has a microscopic pore structure. The mechanical strength of the pressure-sensitive material is improved by adding polyolefin resin, and the conductive carbon black is added to realize the conductive function of the conductive structure 41, and the deformation of the conductive structure 41 is used to realize the connectivity of the closed circuit.

[0063] At the same time, the ammeter 42 can monitor the circuit current, and a corresponding communication module is also provided inside the ammeter 42. The communication module can also transmit the detection data of the ammeter 42 to the monitoring center 45, and then the monitoring center 45 can determine the size of the tension value according to the size of the current, where the monitoring center 45 is a computer monitoring center.

[0064] Among them, the working principle of the intelligent tension monitoring system 4 is as follows:

[0065] The circuit current is monitored by the ammeter 42 and fed back to the monitoring center 45, so as to indirectly monitor the tension on the support through the ammeter 42, thereby achieving real-time monitoring of the tension on the support.

[0066] When the tensile support is not subjected to external pressure, the conductive structure 41 does not deform, the conductive carbon blacks do not (or very little) contact each other, and no (or very little) "conductive path" is formed, resulting in no (or weak) conductivity.

[0067] When the tensile support is subjected to tension, the hydraulic oil in the cavity above the partition 13 squeezes the conductive structure 41, causing the conductive structure 41 to begin to deform, that is, more conductive carbon black inside it contacts each other, and the conductive structure 41 has a certain conductivity and generates a corresponding current;

[0068] When the external tensile force on the tensile support continues to increase, the deformation of the conductive structure 41 further increases, the amount of conductive carbon black in contact with each other further increases, and the conductive ability of the conductive structure 41 is further enhanced and can output a strong current;

[0069] Finally, when the external tensile force on the tensile support is removed, the deformation of the conductive structure 41 disappears due to the good resilience of the conductive structure 41 itself, and the conductive carbon black returns to the original non-contact (or very small) contact state, and the conductive structure 41 shows insulation (or weak conductive) performance again.

[0070] In the above embodiments, those skilled in the art may adopt existing technologies for software control. The present invention only protects the structure of a tensile support that adapts to the bending and torsional deformation of a curved bridge and the mutual connection relationship.
