Anti-seismic beam for bridge anti-seismic support

Abstract

This utility model relates to the field of bridge seismic support technology, specifically a seismic-resistant crossbeam for bridge seismic support, including a seismic-resistant and labor-saving component. The seismic-resistant and labor-saving component has mounting components at both ends. The seismic-resistant and labor-saving component includes a middle beam, with a middle buffer pad fixedly mounted on top of the middle beam, and a mounting frame fixedly mounted inside the middle beam. During use, the middle buffer pad acts as a buffer, and when the bridge presses down on the rubber ring, the rubber ring provides protection, preventing damage to the rotating roller. The damper body acts as an energy dissipator and vibration reducer. Through the design of the rotating plate and shaft, utilizing the lever principle, the force borne by the damper body is reduced, extending its service life and lowering costs. With the mounting components, only the damaged side beams need to be replaced, while the remaining middle beam can continue to be used, thus achieving material savings.

Description

Technical Field

[0001] This utility model relates to the field of bridge seismic support technology, specifically to a seismic-resistant crossbeam for bridge seismic support. Background Technology

[0002] A bridge is generally a structure built over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. During the construction of a bridge, bridge beams are installed to provide support.

[0003] However, existing seismic-resistant beams directly reduce vibrations by installing dampers during use. Due to the lack of a force-saving mechanism, the dampers receive all the vibrations from the bridge. Over time, the lifespan of the dampers is reduced, and the frequency of subsequent replacements is high. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-seismic crossbeam for bridge seismic support, so as to solve the problem of lack of force-saving mechanism mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant crossbeam for bridge seismic support, comprising:

[0006] An earthquake-resistant and labor-saving component, wherein mounting components are provided at both ends of the earthquake-resistant and labor-saving component;

[0007] The earthquake-resistant and labor-saving component includes a central beam, a central buffer pad fixedly mounted on top of the central beam, an installation frame fixedly mounted inside the central beam, a damper body fixedly mounted inside the installation frame, rotating plates abutting at both ends of the damper body, a shaft penetrating through the interior of the rotating plate near its center, an inner rod fixedly connected to the inner side of the end of the rotating plate away from the damper body, a rotating roller connected to the outer wall of the inner rod, and a rubber ring fixedly mounted on the outer wall of the rotating roller.

[0008] Preferably, the mounting assembly includes a side beam, a side buffer pad is fixedly disposed above the side beam, a slider is inserted inside the side beam, a rotating rod is inserted inside the slider, a gear is connected to the outer wall of one end of the rotating rod, toothed plates are meshed on the outer walls of both sides of the gear, a limit plate is fixedly installed at one end of the toothed plate, a turntable is connected to the outer wall of the end of the rotating rod away from the gear, a handle is fixedly connected to the outer wall of the turntable, and the turntable is connected to the slider by a torsion spring.

[0009] Preferably, the rotating plate is rotatably connected to the shaft, the shaft is longer than the distance from the damper body to the rubber ring, and the rotating roller is rotatably connected to the inner rod.

[0010] Preferably, the upper surface of the intermediate buffer pad is higher than the rubber ring, and the inside of the side beam has a groove corresponding to the size of the limiting plate.

[0011] Preferably, the slider is slidably connected to the side beam, and the rotating rod is rotatably connected to the slider.

[0012] Preferably, the gear is fixedly connected to the rotating rod, and the toothed plate and the limiting plate are slidably connected to the slider.

[0013] Preferably, the turntable is fixedly connected to the rotating rod, and the two ends of the torsion spring are fixedly connected to the slider and the turntable, respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) During the use of the anti-seismic crossbeam of this utility model, the bridge will press on the middle buffer pad, which plays a buffering role. The bridge will then press on the rubber ring, which plays a protective role and prevents the rotating roller from being crushed. When the bridge vibrates, the vibration will be transmitted to the rubber ring. When it is pressed down, the rotating roller rotates around the inner rod, the rubber ring rolls outward on the lower surface of the bridge, and the rotating plate rotates around the shaft. The damper body plays a role in energy dissipation and vibration reduction. Through the design of the rotating plate and the shaft, the lever principle is used to reduce the force borne by the damper body, extend the service life of the damper body, and reduce the cost.

[0016] (2) The anti-seismic beam of this utility model is designed with an installation component. Under long-term vibration, the two ends of the beam are more likely to be damaged than the middle. After damage, the handle can be held to make the turntable rotate around the rotating rod. The turntable drives the rotating rod to rotate, the rotating rod drives the gear to rotate, the gear drives the tooth plate and the limiting plate to move, so that the limiting plate retracts into the slider. Then the side beam can be pulled out and replaced. Only the damaged side beam needs to be replaced and the middle beam can be used, thereby achieving the purpose of saving materials.

Detailed implementation method:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 One embodiment of this utility model is an anti-seismic crossbeam for bridge seismic support. The damper body 14 used in this application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0025] Includes: earthquake-resistant and labor-saving component 01, with installation components 02 at both ends of the earthquake-resistant and labor-saving component 01;

[0026] The seismic-resistant and labor-saving component 01 includes a central beam 11. A central buffer pad 12 is fixedly installed on the top of the central beam 11, which serves as a buffer. An installation frame 13 is fixedly installed inside the central beam 11. A damper body 14 is fixedly installed inside the installation frame 13. Rotating plates 15 are abutted at both ends of the damper body 14. A shaft 16 passes through the middle of the rotating plate 15. An inner rod 17 is fixedly connected to the inner side of the end of the rotating plate 15 away from the damper body 14. A rotating roller 18 is connected to the outer wall of the inner rod 17. The rotating roller 18 can rotate around the inner rod 17. A rubber ring 19 is fixedly installed on the outer wall of the rotating roller 18, which protects the rotating roller 18 and prevents it from being crushed.

[0027] Furthermore, the mounting assembly 02 includes a side beam 21, with a side buffer pad 22 fixedly mounted on top of the side beam 21. The side buffer pad 22 serves as a buffer. A slider 23 is inserted inside the side beam 21, guiding the limiting plate 27. A rotating rod 24 is inserted inside the slider 23. When the rotating rod 24 rotates, it drives the gear 25 to rotate, which in turn drives the toothed plate 26 and the limiting plate 27 to move. The gear 25 is connected to the outer wall of one end of the rotating rod 24, and the toothed plate 26 meshes with the outer walls of both sides of the gear 25. The limiting plate 27 is fixedly mounted on one end of the toothed plate 26. After the limiting plate 27 is engaged in the slot of the side beam 21, it can move the side beam 21. The rotating rod 24 is connected to a turntable 28 on the outer wall of the end away from the gear 25. When the turntable 28 rotates, it can drive the rotating rod 24 to rotate. The rotation of the rotating rod 24 drives the gear 25 to rotate. The gear 25 drives the toothed plate 26 and the limiting plate 27 to move. The outer wall of the turntable 28 is fixedly connected to a grip 29. The turntable 28 is connected to the slider 23 through a torsion spring 30. The torsion spring 30 provides elastic force. Under the action of the elastic force of the torsion spring 30, the grip 29 is released, the turntable 28 rotates and drives the rotating rod 24 to rotate. The rotating rod 24 drives the gear 25 to rotate. The gear 25 drives the toothed plate 26 and the limiting plate 27 to move. The limiting plate 27 is locked in the slot of the side beam 21 for limiting.

[0028] Furthermore, the rotating plate 15 is rotatably connected to the shaft 16, and the length of the shaft 16 from the damper body 14 is greater than the length from the rubber ring 19. By utilizing the lever principle, effort is saved. The rotating roller 18 is rotatably connected to the inner rod 17, and the rotating roller 18 can rotate around the inner rod 17.

[0029] Furthermore, the upper surface of the intermediate buffer pad 12 is higher than the rubber ring 19. The intermediate buffer pad 12 plays a buffering role, and the rubber ring 19 plays a role in protecting the rotating roller 18 and preventing the rotating roller 18 from being crushed. The side beam 21 has a slot inside corresponding to the size of the limiting plate 27. After the limiting plate 27 is inserted into the slot of the side beam 21, the side beam 21 can be limited.

[0030] Furthermore, the slider 23 is slidably connected to the side beam 21, ensuring that the slider 23 can be pulled out from the side beam 21 for replacement of the damaged side beam 21. The rotating rod 24 is rotatably connected to the slider 23, ensuring that the slider 23 does not affect the rotation of the rotating rod 24. When the rotating rod 24 rotates, it can drive the gear 25 to rotate, and the gear 25 can drive the toothed plate 26 and the limiting plate 27 to move.

[0031] Furthermore, gear 25 is fixedly connected to rotating rod 24, ensuring that rotating rod 24 can drive gear 25 to rotate when rotating. Gear 25 can drive toothed plate 26 and limiting plate 27 to move. Toothed plate 26 and limiting plate 27 are both slidably connected to slider 23. Slider 23 plays a guiding role for limiting plate 27. After limiting plate 27 is inserted into the slot of side beam 21, it can limit the side beam 21.

[0032] Furthermore, the turntable 28 is fixedly connected to the rotating rod 24, ensuring that the turntable 28 can drive the rotating rod 24 to rotate when it rotates. The rotation of the rotating rod 24 drives the gear 25 to rotate, and the gear 25 drives the toothed plate 26 and the limiting plate 27 to move. The two ends of the torsion spring 30 are fixedly connected to the slider 23 and the turntable 28 respectively. The torsion spring 30 provides elastic force. Under the action of the elastic force of the torsion spring 30, the grip 29 is released, the turntable 28 rotates and drives the rotating rod 24 to rotate, the rotating rod 24 drives the gear 25 to rotate, and the gear 25 drives the toothed plate 26 and the limiting plate 27 to move. The limiting plate 27 is locked in the slot of the side beam 21 for limiting.

[0033] Working principle: During use, the bridge rests on the intermediate buffer pad 12, which acts as a buffer. The bridge then rests on the rubber ring 19, which protects the rotating roller 18 from damage. When the bridge vibrates, the vibration is transmitted to the rubber ring 19. When pressed downwards, the rotating roller 18 rotates around the inner rod 17, and the rubber ring 19 rolls outwards on the lower surface of the bridge. The rotating plate 15 rotates around the shaft 16, and the damper body 14 absorbs energy and reduces vibration. When the side beam 21 is damaged, the handle 29 can be gripped, causing the turntable 28 to rotate around the rotating rod 24. The turntable 28 drives the rotating rod 24 to rotate, which in turn drives the gear 25 to rotate. The gear 25 moves the toothed plate 26 and the limiting plate 27, causing the limiting plate 27 to retract into the slider 23. This allows the side beam 21 to be removed and replaced. The above is the complete working principle of this utility model.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
