Description
Technical Field
[0001] The utility model relates to the technical field of railway engineering construction, and particularly relates to a shock-absorbing bridge bearing. Background Technique
[0002] Railway engineering construction is a complex systematic project, involving work in multiple stages from planning, design, construction to operation and maintenance.
[0003] A railway bridge bearing is an important structural component connecting the upper structure and the lower structure of a railway bridge. It can reliably transfer the reaction force and deformation (displacement and rotation angle) of the upper structure of the railway bridge to the lower structure of the railway bridge, so that the actual stress situation of the structure conforms to the calculated theoretical diagram. When a train is running on the railway bridge, it will cause the bridge to vibrate. If the vibration of the bridge cannot be well reduced and eliminated, it will cause resonance of the railway bridge, thus affecting the safety of the railway bridge.
[0004] When the existing shock-absorbing bridge bearing is in use, it cannot achieve multi-layer shock absorption in the longitudinal direction of the bridge, so the need for longitudinal deformation of the bridge cannot be guaranteed. Content of the Utility Model
[0005] Aiming at the above problems, the purpose of the utility model is to provide a shock-absorbing bridge bearing, which solves the problem that multi-layer shock absorption in the longitudinal direction of the bridge cannot be achieved, so that the need for longitudinal deformation of the bridge cannot be guaranteed. The third shock absorber absorbs the motion energy through elastic deformation to reduce vibration. At the same time, the damper consumes mechanical energy and makes it gradually decelerate and stop, and realizes multi-layer shock absorption in the longitudinal direction of the bridge through the rubber bearing, the second shock absorber and the third shock absorber, so as to guarantee the need for longitudinal deformation of the bridge.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a shock-absorbing bridge bearing, including a base component, a lower layer component, a shock-absorbing component, an upper layer component, and an adjusting component. The base component includes a base bottom plate. The lower layer component includes a lower seat body and a first shock absorber. The shock-absorbing component includes a shock-absorbing slide plate and a second shock absorber. The upper layer component includes an upper top plate. The adjusting component includes an adjusting column and a limiting ring. An installation frame body is welded to the inner side of the upper part of the base bottom plate. Partition plates are symmetrically connected to the inner wall of the lower seat body. Three sliding through holes are opened in the inner side of the lower seat body. A positioning slide rod is slidably arranged inside the sliding through hole. A first spring is sleeved on the outer ring of the end of the positioning slide rod close to the installation frame body. An adjusting groove is opened in the inner side of the lower seat body. A protective ring is connected to the inner wall of the top of the adjusting groove. A rubber bearing is connected to the top of the shock-absorbing slide plate. Upper seat bodies are symmetrically connected to the lower end of the upper top plate. A third shock absorber is connected to the end of the limiting ring away from the second spring.
[0007] The beneficial effects of the present utility model are as follows: when the limit ring moves under the action of the adjusting column, the adjusting column applies a force to the third shock absorber through the limit ring, and the third shock absorber absorbs the kinetic energy through elastic deformation to reduce vibration. At the same time, the damper consumes mechanical energy and gradually slows down and stops it, and realizes multi-layer shock absorption in the longitudinal direction of the bridge through the rubber bearing, the second shock absorber and the third shock absorber, thereby ensuring the needs of the longitudinal deformation of the bridge.
[0008] To install the lower components through the installation frame:
[0009] As a further improvement of the above technical solution: the base plate is provided with screw holes for installation, both ends of the positioning slide rod are connected to the inner wall of the installation frame, and the protective ring is a rubber ring.
[0010] The beneficial effect of this improvement is that when in use, the base plate is stably installed on the bridge pier, and then the rubber bearing and the upper top plate are installed and connected in turn, and the lower components are installed through the setting of the installation frame.
[0011] In order to allow the lower seat of the bridge support to move laterally in the mounting frame through the positioning slide rod and to adapt to the needs of the lateral deformation of the bridge:
[0012] As a further improvement of the above technical solution: there are three positioning slide rods in total and they are slidably connected to the lower seat body. The three positioning slide rods all pass through the lower seat body horizontally. One end of the first spring is connected to the outer wall of the lower seat body, and the end of the first spring away from the outer wall of the lower seat body is connected to the inner wall of the mounting frame.
[0013] The beneficial effect of this improvement is that when the lateral horizontal force on the bridge is too large and acts on the bridge support, the lower seat body on the bridge support will move laterally inside the installation frame through the positioning slide rod, and be used to adapt to the needs of the lateral deformation of the bridge, thereby avoiding damage to the bridge support due to excessive lateral horizontal force.
[0014] In order for the first shock absorber to absorb the kinetic energy and reduce vibration through elastic deformation:
[0015] As a further improvement of the above technical solution: the outer walls at both ends of the lower seat body are symmetrically connected with first shock absorbers, the end of the first shock absorber away from the lower seat body is connected to the inner wall of the mounting frame, the number of the first shock absorbers is the same as the number of the first springs, the first shock absorber includes a damper, and the first shock absorber is arranged above the first spring.
[0016] The beneficial effect of this improvement is that when the lower seat body moves laterally in the installation frame through the positioning slide rod to adapt to the needs of lateral deformation of the bridge, the lower seat body applies a force to the connected first shock absorber, and the first shock absorber absorbs kinetic energy through elastic deformation to reduce vibration. At the same time, the damper consumes mechanical energy and gradually slows down and stops it.
[0017] In order to reduce the vibration amplitude of the bridge, the rubber bearing consumes a lot of energy through internal friction when it is subjected to force:
[0018] As a further improvement of the above technical solution: a mounting nail is welded on the top of the shock-absorbing slide plate, and the mounting nail is inserted into the inner side of the rubber support. The rubber support is a rectangular high-damping rubber support. The second shock absorber is installed on the top of the lower bottom surface of the lower seat body. The end of the second shock absorber away from the lower seat body is connected to the shock-absorbing slide plate. The second shock absorber includes a damper, and the second shock absorber is arranged at equal intervals between two adjacent adjustment columns.
[0019] The beneficial effects of this improvement are: after completing the installation of the base plate, clean and dry the bottom surface of the rubber bearing, then evenly apply an appropriate amount of industrial glue, and then fit the bottom surface of the rubber bearing to the top of the shock-absorbing slide plate. At the same time, insert the installation nails into the inner side of the rubber bearing, and apply a certain amount of pressure to the rubber bearing to ensure close contact until the industrial glue solidifies. When the rubber bearing is under force, it consumes a lot of energy through internal friction, thereby reducing the vibration amplitude of the bridge. By setting the second shock absorber, it is used to adapt to the needs of longitudinal deformation of the bridge.
[0020] In order to ensure the stability of the sliding connection between the upper and lower seat bodies through the setting of the limit plate:
[0021] As a further improvement of the above technical solution: the end of the upper seat body away from the upper top plate is connected to a limiting vertical plate, and the limiting vertical plate is slidably inserted into the position between the inner wall of the lower seat body and the partition plate, and the upper seat body is slidably connected to the partition plate through the limiting vertical plate.
[0022] The beneficial effect of this improvement is: after completing the installation of the base plate, the bridge beam is erected on the upper top plate, and the upper top plate and the bridge beam are fixed. When the upper top plate is subjected to the action force, the upper top plate moves and drives the upper seat and the limit vertical plate to move. The setting of the limit vertical plate is used to ensure the stability of the sliding connection between the upper seat and the lower seat.
[0023] In order to adjust the column to slide toward the bottom of the adjustment slot after the force of the shock-absorbing slide is applied to the adjustment column:
[0024] As a further improvement of the above technical solution: the limiting ring is slidably installed on the inner side of the adjusting groove, the top of the adjusting column is connected to the bottom of the shock-absorbing slide, the adjusting column extends away from the bottom of the shock-absorbing slide to the inner side of the adjusting groove and is connected to the limiting ring, the outer ring of the adjusting column is provided with a second spring, the upper end of the second spring is connected to the bottom of the shock-absorbing slide, and the lower end of the second spring is connected to the lower bottom wall of the lower seat body.
[0025] The beneficial effect of this improvement is that after the adjusting column is subjected to the force of the shock-absorbing slide plate, the adjusting column is forced to slide toward the bottom of the adjusting groove. At the same time, in this process, the shock-absorbing slide plate squeezes the second spring, and the second spring is deformed under the force.
[0026] In order to achieve multi-layer vibration reduction in the longitudinal direction of the bridge through rubber bearings, second shock absorbers and third shock absorbers:
[0027] As a further improvement of the above technical solution: the third shock absorber is installed on the inner side of the adjustment groove, and the third shock absorber includes a damper.
[0028] The beneficial effect of this improvement is: when the limit ring moves under the action of the adjusting column, the adjusting column applies force to the third shock absorber through the limit ring, and the third shock absorber absorbs kinetic energy through elastic deformation to reduce vibration.

The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present utility model.
[0036] As Figures 1-5As shown in the figure, a shock-absorbing bridge bearing includes a base assembly 1, a lower layer assembly 2, a shock-absorbing assembly 3, an upper layer assembly 4, and an adjustment assembly 5. The base assembly 1 includes a base bottom plate 11. The lower layer assembly 2 includes a lower layer seat body 21 and a first shock absorber 28. The shock-absorbing assembly 3 includes a shock-absorbing sliding plate 31 and a second shock absorber 33. The upper layer assembly 4 includes an upper layer top plate 41. The adjustment assembly 5 includes an adjustment column 51 and a limit ring 53. An installation frame body 12 is welded to the inner side of the upper part of the base bottom plate 11. Partition plates 22 are symmetrically connected to the inner wall of the lower layer seat body 21. Three sliding through holes 23 are formed in the inner side of the lower layer seat body 21. A positioning slide bar 24 is slidably arranged inside the sliding through hole 23. A first spring 25 is sleeved on the outer ring of the positioning slide bar 24 near one end of the installation frame body 12. An adjustment groove 26 is formed in the inner side of the lower layer seat body 21. A protective ring 27 is connected to the inner wall of the top of the adjustment groove 26. A rubber bearing 32 is connected to the top of the shock-absorbing sliding plate 31. Upper layer seat bodies 42 are symmetrically connected to the lower end of the upper layer top plate 41. A third shock absorber 54 is connected to one end of the limit ring 53 away from the second spring 52. The base bottom plate 11 is provided with screw holes for installation. Both ends of the positioning slide bar 24 are connected to the inner wall of the installation frame body 12. The protective ring 27 is a rubber ring; during use, the base bottom plate 11 is stably installed on the bridge pier, and then the rubber bearing 32 and the upper layer top plate 41 are installed and connected in sequence. Through the setting of the installation frame body 12, it is used for the installation of the lower layer assembly 2. There are three positioning slide bars 24 which are slidably connected to the lower layer seat body 21. The three positioning slide bars 24 all horizontally penetrate the lower layer seat body 21. One end of the first spring 25 is connected to the outer wall of the lower layer seat body 21, and the end of the first spring 25 away from the outer wall of the lower layer seat body 21 is connected to the inner wall of the installation frame body 12; when the horizontal force on the bridge is too large and acts on the bridge bearing, the lower layer seat body 21 on the bridge bearing generates a horizontal movement in the installation frame body 12 through the positioning slide bar 24 to meet the need of the bridge's lateral deformation, thereby avoiding damage to the bridge bearing due to excessive horizontal force. Symmetrically connected to the outer walls at both ends of the lower layer seat body 21 are first shock absorbers 28. One end of the first shock absorber 28 away from the lower layer seat body 21 is connected to the inner wall of the installation frame body 12. The number of the first shock absorbers 28 is the same as the number of the first springs 25. The first shock absorber 28 includes a damper. The first shock absorber 28 is arranged above the first spring 25;When the lower seat body 21 generates a lateral movement in the mounting frame 12 through the positioning slide bar 24 to meet the need of the lateral deformation of the bridge, the lower seat body 21 applies a force to the connected first shock absorber 28. The first shock absorber 28 absorbs the movement energy through elastic deformation to reduce vibration. At the same time, the damper consumes mechanical energy and makes it gradually decelerate and stop. The installation nails 34 are welded to the top of the shock absorber slide plate 31. The installation nails 34 are inserted into the inner side of the rubber bearing 32. The rubber bearing 32 is a rectangular high-damping rubber bearing. The second shock absorber 33 is installed on the top of the bottom surface of the lower seat body 21. One end of the second shock absorber 33 away from the lower seat body 21 is connected to the shock absorber slide plate 31. The second shock absorber 33 includes a damper. The second shock absorbers 33 are arranged at equal intervals between two adjacent adjusting columns 51. After the installation of the base seat plate 11 is completed, the bottom surface of the rubber bearing 32 is cleaned and dried, and then an appropriate amount of industrial glue is evenly applied. Then the bottom surface of the rubber bearing 32 is attached to the top of the shock absorber slide plate 31. At the same time, the installation nails 34 are inserted into the inner side of the rubber bearing 32, and a certain pressure is applied to the rubber bearing 32 to ensure close contact until the industrial glue cures. When the rubber bearing 32 is stressed, it consumes a large amount of energy through internal friction, thereby being able to reduce the vibration amplitude of the bridge. Through the setting of the second shock absorber 33, it is used to meet the need of the longitudinal deformation of the bridge. One end of the upper seat body 42 away from the upper top plate 41 is connected with a limiting vertical plate 43. The limiting vertical plate 43 is slidably inserted into the position between the inner wall of the lower seat body 21 and the partition plate 22. The upper seat body 42 is slidably connected with the partition plate 22 through the limiting vertical plate 43. After the installation of the base seat plate 11 is completed, the bridge beam is erected on the upper top plate 41, and the upper top plate 41 is fixed to the bridge beam. When the upper top plate 41 is subjected to a force, the upper top plate 41 moves and drives the upper seat body 42 and the limiting vertical plate 43 to move. Through the setting of the limiting vertical plate 43, it is used to ensure the stability of the sliding connection between the upper seat body 42 and the lower seat body 21. The limiting ring 53 is slidably installed inside the adjusting groove 26. The top of the adjusting column 51 is connected to the bottom of the shock absorber slide plate 31. The bottom of the adjusting column 51 away from the shock absorber slide plate 31 extends into the adjusting groove 26 and is connected to the limiting ring 53. A second spring 52 is arranged on the outer ring of the adjusting column 51. The upper end of the second spring 52 is connected to the bottom of the shock absorber slide plate 31. The lower end of the second spring 52 is connected to the wall body of the bottom surface of the lower seat body 21. After the adjusting column 51 is subjected to the force of the shock absorber slide plate 31, the adjusting column 51 slides downward along the adjusting groove 26. At the same time, during this process, the shock absorber slide plate 31 squeezes the second spring 52, and the second spring 52 deforms under the force. The third shock absorber 54 is installed inside the adjusting groove 26. The third shock absorber 54 includes a damper;When the limit ring 53 moves under the action of the adjusting column 51, the adjusting column 51 exerts a force on the third shock absorber 54 through the limit ring 53. The third shock absorber 54 absorbs the motion energy through elastic deformation to reduce vibration. At the same time, the damper consumes mechanical energy and gradually decelerates it to a stop, and realizes multi-layer shock absorption in the longitudinal direction of the bridge through the rubber bearing 32, the second shock absorber 33, and the third shock absorber 54, so as to meet the needs of ensuring the longitudinal deformation of the bridge.;
[0037] The working principle of the present utility model is as follows: During use, the base bottom plate 11 is stably installed on the bridge pier. After the installation of the base bottom plate 11 is completed, the lower bottom surface of the rubber bearing 32 is cleaned and dried, and then an appropriate amount of industrial glue is evenly applied. Then, the lower bottom surface of the rubber bearing 32 is attached to the top of the shock-absorbing slide plate 31. At the same time, the installation nails 34 are inserted into the inner side of the rubber bearing 32, and a certain pressure is applied to the rubber bearing 32 to ensure close contact until the industrial glue cures. The bridge beam body is erected on the upper top plate 41, and the upper top plate 41 is fixed to the bridge beam body. When the upper top plate 41 is subjected to a force, the upper top plate 41 moves and drives the upper seat body 42 and the limit vertical plate 43 to move. Through the setting of the limit vertical plate 43, it is used to ensure the stability of the sliding connection between the upper seat body 42 and the lower seat body 21. Through the setting of the installation frame body 12, it is used for the installation of the lower component 2. After the adjusting column 51 is subjected to the force of the shock-absorbing slide plate 31, the adjusting column 51 slides downward along the bottom of the adjusting groove 26 under the force. At the same time, during this process, the shock-absorbing slide plate 31 squeezes the second spring 52, and the second spring 52 deforms under the force. When the limit ring 53 moves under the action of the adjusting column 51, the adjusting column 51 exerts a force on the third shock absorber 54 through the limit ring 53. The third shock absorber 54 absorbs the motion energy through elastic deformation to reduce vibration. At the same time, the damper consumes mechanical energy and gradually decelerates it to a stop. When the rubber bearing 32 is subjected to a force, it consumes a large amount of energy through internal friction, so as to be able to reduce the vibration amplitude of the bridge. Through the setting of the second shock absorber 33, it is used to meet the needs of the longitudinal deformation of the bridge, and multi-layer shock absorption in the longitudinal direction of the bridge is realized through the rubber bearing 32, the second shock absorber 33, and the third shock absorber 54, so as to meet the needs of ensuring the longitudinal deformation of the bridge. When the horizontal force on the bridge in the transverse direction is too large and acts on the bridge bearing, the lower seat body 21 on the bridge bearing moves horizontally in the installation frame body 12 through the positioning slide rod 24, and is used to meet the needs of the transverse deformation of the bridge, so as to avoid damage to the bridge bearing due to excessive horizontal force in the transverse direction. When the lower seat body 21 moves horizontally in the installation frame body 12 through the positioning slide rod 24 to meet the needs of the transverse deformation of the bridge, the lower seat body 21 exerts a force on the connected first shock absorber 28. The first shock absorber 28 absorbs the motion energy through elastic deformation to reduce vibration. At the same time, the damper consumes mechanical energy and gradually decelerates it to a stop.
