A type of prefabricated bridge vibration damping bearing

Abstract

This invention belongs to the field of bridge vibration reduction technology, specifically a modular bridge vibration damping bearing. The proposed solution includes a mounting frame with mounting holes on both sides, and vibration damping components on the outer sides of both mounting holes. A push-out component is provided on the mounting frame, comprising a mounting base and a push-out plate. This invention addresses the safety hazard posed by providing a temporary support component. During maintenance or replacement of the vibration damping component, the bridge and the bearing are not in contact after the component is removed. In this state, a cylinder is activated during replacement or maintenance, lifting a pressure plate and bringing it into contact with the bottom of a support plate. The pressure plate then supports the bridge section, ensuring that the bearing and bridge are in a state of mutual compression contact after the vibration damping component is removed, thus eliminating the potential safety hazard.

Description

Technical Field

[0001] This invention relates to the field of bridge vibration reduction technology, and in particular to a modular bridge vibration reduction bearing. Background Technology

[0002] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. A bridge typically consists of a superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles. The substructure includes abutments, piers, and foundations. Supports are force-transmitting devices installed at the points where the bridge span structure supports the piers or abutments. Ancillary structures include approach slabs, tapered slopes, revetments, and diversion works.

[0003] In existing bridge vibration damping bearings, they are generally installed directly inside the mounting frame. Over long-term use, the vibration damping bearings will gradually wear down. When they wear down to a certain extent, they will lose their damping effect and need to be replaced. The current installation of vibration damping bearings inside the mounting frame means that when replacing the vibration damping bearings, the mounting frame needs to be disassembled, and then the vibration damping bearings inside the mounting frame need to be replaced. This makes the maintenance and replacement of vibration damping bearings cumbersome and reduces the service value of the bridge vibration damping bearings. Summary of the Invention

[0004] This invention proposes a modular bridge vibration damping bearing, comprising a mounting frame with mounting holes on both sides, and vibration damping components on the outer sides of both mounting holes. The mounting frame also includes an ejector assembly comprising a mounting base and ejector plates. The mounting base is fixedly connected to the bottom inner wall of the mounting frame, and two fixing plates are fixedly connected to the top of the mounting base. The ejector plates are connected to the outer sides of the fixing plates via hinges. A horizontal plate is fixedly connected to the top of each of the two ejector plates. Adjustment holes are provided at both ends of the mounting frame, and multiple connecting rods are inserted into the interior of each adjustment hole. The connecting rod has a single push rod fixedly connected to one side of the outer wall of multiple connecting rods located at one end, and a single ejector column fixedly connected to the other side of the multiple connecting rods located at one end. The ejector column contacts the outer wall of the mounting base and the ejector plate. An adjusting rail is fixedly connected to the side of the mounting frame above the push rod, and two adjusting sliders are slidably connected inside the adjusting rail. A connecting frame is fixedly connected to one side of each of the two adjusting sliders. A fixing ring plate is fixedly connected to the bottom of the connecting frame. Friction blocks are fixedly connected at equal intervals to the inner side of the fixing ring plate. The fixing ring plate is located at both ends of the push rod.

[0005] As a further embodiment of the present invention, the shock absorption assembly includes a shock absorption seat, and two sliding grooves are opened on both sides of the inner wall of the shock absorption seat. A limiting slide rod is slidably connected to the inner wall of each sliding groove, and the same contact seat is fixedly connected to the outer side of the four limiting slide rods.

[0006] As a further embodiment of the present invention, the bottom of the contact seat is fixedly connected with shock-absorbing springs at equal intervals, and the other end of each shock-absorbing spring is fixedly connected to the bottom inner wall of the shock-absorbing seat. Both sides of the contact seat are fixedly connected with guide plates, and both ends of the top of the contact seat are provided with fitting grooves.

[0007] As a further embodiment of the present invention, the top of the mounting frame is provided with a temporary support component, and the temporary support component includes a baffle and a support plate, with the baffle fixedly connected to the top of the mounting frame.

[0008] As a further embodiment of the present invention, the top of the baffle is fixedly connected with a telescopic rod at equal intervals, and the support plate is fixedly connected to the top of the multiple telescopic rods. A bonding plate is fixedly connected to one side of the support plate, and the bonding plate and the bonding groove are compatible.

[0009] As a further embodiment of the present invention, the top of the baffle is fixedly connected to two base plates, and the top of each of the two base plates is fixedly connected to a cylinder. The output end of each of the two cylinders is fixedly connected to a pressure plate, and the pressure plate is in contact with the bottom of the support plate.

[0010] As a further embodiment of the present invention, the inner walls on both sides of the mounting frame are provided with limiting components, and the limiting components include a limiting plate and a lifting plate.

[0011] As a further embodiment of the present invention, two sliding rails are fixedly connected to the inner walls of both sides of the mounting frame, and sliding rods are slidably connected to the inner walls of the four sliding rails. The two sliding rods located on one side are fixedly connected to one side of the lifting plate.

[0012] As a further embodiment of the present invention, a plurality of limiting springs are fixedly connected to the other side of the lifting plate, and a limiting plate is fixedly connected to the other end of the plurality of limiting springs. A plurality of second telescopic rods are fixedly connected to the side of the limiting plate facing the lifting plate, and the other end of the plurality of second telescopic rods is fixedly connected to one side of the lifting plate.

[0013] As a further embodiment of the present invention, the other side of the limiting plate is connected to a pressing plate at equal intervals via a hinge, and each pressing plate is fixedly connected to a pressing spring at equal intervals on the side facing the limiting plate. The other end of each pressing spring is fixedly connected to the outside of the limiting plate, and a friction plate is fixedly connected to the other side of each pressing plate at equal intervals.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. With the ejector assembly installed, the shock absorber assembly is inserted into the mounting frame through the mounting holes. Then, the push rod is manually pushed, causing the ejector pin on the connecting rod to move towards the fixed plate. This causes the ejector pin to slowly tilt upwards, ejecting the shock absorber assembly from the top of the mounting frame. The shock absorber assembly is then restrained by baffles at both ends. After the shock absorber assembly is ejected, the sliding adjustment slider causes the fixing ring plate on the connecting frame to contact the push rod, thus fixing the push rod and achieving shock absorption. The support of the component limits the friction block on the inner side of the fixed ring plate, which increases the frictional resistance between the push rod and the fixed ring plate, further improving the tightness of the connection. When the damping component is damaged after long-term use, the sliding adjustment slider separates the fixed ring plate from the push rod. The weight of the damping component itself presses against the ejector plate below the horizontal plate, causing the ejector column to slide outwards towards the mounting frame. The damping component slowly descends to the mounting hole. Once it overlaps with the mounting hole, it can be removed. This process is convenient and efficient, improving the ease of replacement and maintenance of the damping component, thereby enhancing the use value of the bridge damping bearing.

[0016] 2. By setting up a limiting component, during the process of moving the damping component into the mounting frame, the damping seat first contacts the limiting plate. During the contact process, the limiting spring and the second telescopic rod are compressed, and the damping component slowly moves into the mounting frame. When the damping seat contacts the friction plate on the compression plate, the compression caused by the damping seat compresses the compression spring, thereby increasing the tightness of the connection between the damping component and the limiting component. The damping component is fixed by the cooperation of the limiting component and the two baffles. During the operation of the damping component, the compression spring and the limiting spring play a certain damping role, thereby improving the damping effect of the bridge damping bearing.

[0017] 3. With the provision of temporary support components, when the shock absorber components are repaired or replaced, the bridge and the shock absorber bearing are not in contact after the components are removed. This situation poses a certain safety hazard. In this invention, when the shock absorber components are replaced or repaired, a cylinder is activated, which lifts the pressure plate, causing it to contact the bottom of the support plate. The pressure plate then drives the support plate to support the bridge at that point, ensuring that after the shock absorber components are removed, the shock absorber bearing and the bridge are in a state of mutual compression contact, thus eliminating the potential safety hazard.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-7A modular bridge vibration damping bearing includes a mounting frame 1. Mounting holes 7 are provided on both sides of the mounting frame 1, and vibration damping components are provided on the outer sides of both mounting holes 7. An ejector assembly is provided on the mounting frame 1, comprising a mounting base 14 and an ejector plate 15. The mounting base 14 is fixedly connected to the bottom inner wall of the mounting frame 1, and two fixing plates 18 are fixedly connected to the top of the mounting base 14. The ejector plate 15 is connected to the outer side of the fixing plates 18 via hinges. A horizontal plate 19 is fixedly connected to the top of each of the two ejector plates 15. Adjustment holes 11 are provided at both ends of the mounting frame 1, and multiple connecting rods 9 are inserted into the interior of each adjustment hole 11, located at one end. The same push rod 10 is fixedly connected to one side of the outer wall of the multiple connecting rods 9 at one end, and the same ejector column 16 is fixedly connected to the other side of the multiple connecting rods 9 at one end. The ejector column 16 is in contact with the outer wall of the mounting base 14 and the ejector plate 15. An adjustment rail 13 is fixedly connected to the side of the mounting frame 1 above the push rod 10, and two adjustment sliders 17 are slidably connected inside the adjustment rail 13. A connecting frame 12 is fixedly connected to one side of each of the two adjustment sliders 17. A fixing ring plate 8 is fixedly connected to the bottom of the connecting frame 12. Friction blocks 20 are fixedly connected at equal intervals to the inner side of the fixing ring plate 8. The fixing ring plate 8 is located at both ends of the push rod 10.

[0028] By incorporating an ejector assembly, during the installation of the shock absorber assembly, it is inserted into the mounting frame 1 through the mounting hole 7. Then, the push rod 10 is manually pushed, causing the ejector column 16 on the connecting rod 9 to move closer to the fixed plate 18. This causes the ejector column 16 to slowly tilt upwards, ejecting the shock absorber assembly above the horizontal plate 19 from the top of the mounting frame 1. The baffles 30 at both ends constrain the shock absorber assembly. After the shock absorber assembly is ejected, the sliding adjustment slider 17 causes the fixing ring plate 8 on the connecting frame 12 to contact the push rod 10, thus fixing the push rod 10 and achieving... The current support limitation of the damping component, the friction block 20 on the inner side of the fixed ring plate 8 increases the frictional resistance between the push rod 10 and the fixed ring plate 8, further improving the tightness of the connection. When the damping component is damaged after long-term use, the sliding adjustment slider 17 is slidable to separate the fixed ring plate 8 from the push rod 10. The weight of the damping component itself squeezes the ejector plate 15 below the horizontal plate 19, causing the ejector column 16 to slide outward of the mounting frame 1. The damping component slowly descends to the mounting hole 7. When it overlaps with the mounting hole 7, it is removed. This is convenient and efficient, improves the convenience of replacing and maintaining the damping component, and thus improves the use value of the bridge damping bearing.

[0029] Reference Figure 6 and Figure 7The shock absorption assembly includes a shock absorption seat 6, and two sliding grooves are opened on both sides of the inner wall of the shock absorption seat 6. A limiting slide rod 35 is slidably connected to the inner wall of each sliding groove, and the same contact seat 5 is fixedly connected to the outer side of the four limiting slide rods 35.

[0030] In this invention, shock-absorbing springs 37 are fixedly connected at equal intervals to the bottom of the contact seat 5, and the other ends of multiple shock-absorbing springs 37 are fixedly connected to the bottom inner wall of the shock-absorbing seat 6. Guide plates 34 are fixedly connected to both sides of the contact seat 5, and fitting grooves 36 are opened at both ends of the top of the contact seat 5.

[0031] Reference Figure 5 The top of the mounting frame 1 is provided with a temporary support assembly, which includes a baffle 30 and a support plate 2. The baffle 30 is fixedly connected to the top of the mounting frame 1.

[0032] In this invention, a telescopic rod 4 is fixedly connected at equal intervals to the top of the baffle 30, and a support plate 2 is fixedly connected to the top of multiple telescopic rods 4. A bonding plate 3 is fixedly connected to one side of the support plate 2, and the bonding plate 3 and the bonding groove 36 are compatible.

[0033] In this invention, two base plates 31 are fixedly connected to the top of the baffle 30, and cylinders 33 are fixedly connected to the top of each of the two base plates 31. Pressure plates 32 are fixedly connected to the output ends of the two cylinders 33, and the pressure plates 32 are in contact with the bottom of the support plate 2.

[0034] By incorporating a temporary support component, when the shock absorber is removed for maintenance or replacement, the bridge and the shock absorber bearing are not in contact, posing a safety hazard. In this invention, when the shock absorber is replaced or maintained, cylinder 33 is activated, causing the pressure plate 32 to rise and contact the bottom of the support plate 2. The pressure plate 32 then supports the bridge at that point, ensuring that after the shock absorber is removed, the shock absorber bearing and the bridge are in a state of mutual compression contact, thus eliminating potential safety hazards.

[0035] Reference Figure 4 The inner walls on both sides of the mounting frame 1 are provided with limiting components, and the limiting components include a limiting plate 22 and a lifting plate 27.

[0036] In this invention, two sliding rails 21 are fixedly connected to the inner walls of both sides of the mounting frame 1, and sliding rods 28 are slidably connected to the inner walls of the four sliding rails 21. The two sliding rods 28 located on one side are fixedly connected to one side of the lifting plate 27.

[0037] In this invention, a plurality of limiting springs 26 are fixedly connected to the other side of the lifting plate 27, and a limiting plate 22 is fixedly connected to the other end of the plurality of limiting springs 26. A plurality of second telescopic rods 29 are fixedly connected to the side of the limiting plate 22 facing the lifting plate 27, and the other end of the plurality of second telescopic rods 29 is fixedly connected to one side of the lifting plate 27.

[0038] In this invention, the other side of the limiting plate 22 is connected to the pressing plate 23 by hinges at equal distances, and each pressing plate 23 is fixedly connected to the side of the limiting plate 22 at equal distances with the pressing spring 24. The other end of each pressing spring 24 is fixedly connected to the outside of the limiting plate 22, and each pressing plate 23 is fixedly connected to the other side at equal distances with the friction plate 25.

[0039] By setting a limiting component, during the process of moving the damping component into the mounting frame 1, the damping seat 6 first contacts the limiting plate 22. During the contact, the limiting spring 26 and the second telescopic rod 29 are compressed, and the damping component slowly moves into the mounting frame 1. When the damping seat 6 contacts the friction plate 25 on the compression plate 23, the compression caused by the damping seat 6 compresses the compression spring 24, thereby increasing the tightness of the connection between the damping component and the limiting component. The damping component is fixed by the cooperation of the limiting component and the two baffles 30. During the operation of the damping component, the compression spring 24 and the limiting spring 26 play a certain damping role, thereby improving the damping effect of the bridge damping bearing.

[0040] During use, when installing the shock absorber assembly, it is inserted into the mounting frame 1 through the mounting hole 7. During insertion, the shock absorber seat 6 first contacts the limiting plate 22. During this contact, the limiting spring 26 and the second telescopic rod 29 are compressed, and the shock absorber assembly slowly moves into the mounting frame 1. When the shock absorber seat 6 contacts the friction plate 25 on the compression plate 23, the compression caused by the shock absorber seat 6 compresses the compression spring 24, thereby increasing the tightness of the connection between the shock absorber assembly and the limiting assembly. The shock absorber assembly is fixed by the cooperation of the limiting assembly and the two baffles 30. After the shock absorber assembly is inside the mounting frame 1, the push rod 10 is manually pushed. The push rod 10 drives the ejector column 16 on the connecting rod 9 to move towards the fixed plate 18, thereby causing the ejector column 16 to slowly tilt upward, and then the shock absorber assembly located above the horizontal plate 19 is moved upward. The shock absorber is ejected from the top of the mounting frame 1, and the baffles 30 at both ends limit the shock absorber assembly. After the shock absorber assembly is ejected, the sliding adjustment slider 17 drives the fixing ring plate 8 on the connecting frame 12 to contact the push rod 10. The fixing ring plate 8 fixes the push rod 10, thereby achieving the support and limitation of the shock absorber assembly. When the shock absorber assembly is damaged after long-term use, the cylinder 33 is activated. The cylinder 33 drives the pressure plate 32 to rise, so that the pressure plate 32 contacts the bottom of the support plate 2. The pressure plate 32 drives the support plate 2 to support this part of the bridge. Then, the sliding adjustment slider 17 separates the fixing ring plate 8 from the push rod 10. The weight of the shock absorber assembly itself squeezes the ejection plate 15 below the horizontal plate 19, causing the ejection column 16 to slide outward of the mounting frame 1. The shock absorber assembly slowly descends to the mounting hole 7. When it overlaps with the mounting hole 7, it is taken out.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
