Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration reduction technology in building and bridge engineering, specifically to a damping type anti-fall beam vibration reduction bearing. Background Technology
[0002] In bridge design, bearings are key components that transfer the loads from the superstructure to the substructure and accommodate the rotation and displacement of the superstructure. Bearings are classified into pot bearings, ball bearings, lead-core rubber bearings, and friction pendulum bearings, among others.
[0003] In practical applications, when an earthquake occurs, the horizontal displacement between the upper and lower bearing plates of ordinary rubber bearings and ball bearings cannot be effectively restrained when they encounter earthquakes or major vibration impacts, which can easily lead to beam collapse.
[0004] Current technology primarily uses steel wire ropes fixed at the upper and lower ends of the support to achieve vibration reduction and prevent beam collapse. However, the steel wire ropes are generally locked with rope clamps. After locking, the steel wire rope forms a taut, spiral shape. Each coil of the spiral is locked, limiting energy consumption and travel. Furthermore, due to installation errors, the length of each coil of the steel wire rope may be uneven after locking. This unevenness in length leads to uneven stress distribution when under load, with the shortest steel wire rope bearing the load first. The coils cannot automatically coordinate and adapt, resulting in a risk of gradual breakage. Utility Model Content
[0005] The purpose of this invention is to provide a damping anti-fall beam shock absorber, which can effectively increase the energy dissipation stroke, and the wire rope can automatically coordinate and adapt to avoid the risk of gradual breakage.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:
[0007] A damping-type anti-fall beam vibration reduction bearing includes an upper bearing plate, a lower bearing plate, and a bearing core located between the upper and lower bearing plates. A steel wire rope is wound between the upper and lower bearing plates and located outside the bearing core. The steel wire rope includes a first steel wire rope, a second steel wire rope, and a transition steel wire rope. The first steel wire rope is located outside the second steel wire rope, and the second steel wire rope is located outside the bearing core. The first steel wire rope and the second steel wire rope respectively form multiple relaxed first semicircular rings and second semicircular rings distributed between the upper and lower bearing plates. The first semicircular rings and the second semicircular rings are arranged opposite each other. The transition steel wire rope connects adjacent first semicircular rings and adjacent second semicircular rings.
[0008] In this design, the upper bearing plate is connected to the superstructure, and the lower bearing plate is connected to the substructure of the bridge (such as piers). The bearing core is located between the upper and lower bearing plates, bearing the vertical load of the bridge. The first wire rope is located outside the second wire rope, forming multiple relaxed first semicircular loops distributed in a ring shape between the upper and lower bearing plates. Under the influence of earthquakes or strong winds, the first wire rope absorbs energy through tensile deformation, limiting the relative displacement of the upper and lower bearing plates and preventing beam collapse. The second wire rope is located outside the bearing core and inside the first wire rope, forming multiple relaxed second semicircular loops opposite to the first semicircular loops. The second wire rope works in conjunction with the first wire rope, providing shock absorption and beam collapse prevention functions, enhancing the overall stability of the bearing. Transition wire ropes connect adjacent first and second semicircular loops, ensuring the integrity and continuity of the wire rope system, enabling the first and second wire ropes to work together to absorb energy and limit displacement.
[0009] Under the influence of earthquakes or strong winds, bridges will experience horizontal displacement. The wire rope system (including the first wire rope, the second wire rope, and the transition wire rope) absorbs energy through tensile deformation, reducing the amplitude of bridge vibration. The relaxed first and second semi-circular rings gradually straighten under stress, providing a damping effect. Compared to their locked state, the relaxed first and second semi-circular rings have a longer energy-dissipating stroke, resulting in better vibration reduction. Furthermore, even if the lengths of the first and second semi-circular rings differ due to installation errors, they can automatically coordinate and adapt under stress, preventing uneven stress due to length discrepancies. Therefore, the wire ropes are less prone to gradual breakage. When the horizontal displacement of the bridge exceeds a certain limit, the wire rope system restricts the relative displacement of the upper and lower bearing plates, preventing the bridge from detaching from the supports.
[0010] Optionally, the transition wire rope includes a first transition wire rope and a second transition wire rope. The first transition wire rope is located above the second transition wire rope. The first transition wire rope connects the upper ends of adjacent first semicircular rings and adjacent second semicircular rings. The second transition wire rope connects the lower ends of adjacent first semicircular rings and adjacent second semicircular rings. The first transition wire rope and the second transition wire rope are staggered vertically.
[0011] Optionally, the first wire rope, the first transition wire rope, and the second transition wire rope are integrated into a single unit, and the second wire rope, the first transition wire rope, and the second transition wire rope are integrated into a single unit.
[0012] Optionally, a first retaining ring is provided below the upper seat plate, and a second retaining ring corresponding to the first retaining ring is provided above the lower seat plate. Multiple sets of limiting devices for restricting the slippage of the transition wire rope are provided between the first retaining ring and the upper seat plate, and between the second retaining ring and the lower seat plate.
[0013] Optionally, the limiting member is a limiting bolt, which passes through the upper seat plate from top to bottom and connects to the first retaining ring, and passes through the lower seat plate from bottom to top and connects to the second retaining ring.
[0014] Optionally, each set of limiting components includes four limiting bolts, which form a rectangle and are distributed at the four corners of the rectangle.
[0015] Optionally, two limiting bolts distributed circumferentially in the same set of limiting components form a cavity that allows the wire rope to pass through, with the upper and lower ends of the first semicircular ring located in the corresponding cavity, and the upper and lower ends of the second semicircular ring located in the corresponding cavity.
[0016] Optionally, the upper cavity is composed of two limiting bolts distributed circumferentially in the same set of limiting components, an upper seat plate, and a first retaining ring. The lower cavity is composed of two limiting bolts distributed circumferentially in the same set of limiting components, a lower seat plate, and a second retaining ring. The cavity is smaller in the middle and larger at both ends. The inner wall of the cavity is an arc-shaped surface protruding towards the center of the cavity. The arc-shaped surface is composed of the sidewalls of the limiting bolts.
[0017] Optionally, two limiting bolts distributed circumferentially on the inner side of two adjacent sets of limiting members restrict the first transition wire rope and the second transition wire rope from sliding out, and the first transition wire rope and the second transition wire rope are located inside the two limiting bolts on the inner side.
[0018] Optionally, the support core can be any one of a rubber support, a spherical support, a friction pendulum support, or a vibration damping and isolation support.
[0019] The beneficial effects of this utility model are:
[0020] In existing technologies, wire ropes are generally distributed in a spiral shape on the side of the support. Both the upper and lower ends of the spiral wire rope are locked, keeping the rope taut and resulting in a shorter energy-dissipating stroke. Compared to existing techniques where the wire ropes are arranged in a ring and locked, this invention allows the wire rope system (including a first wire rope, a second wire rope, and a transition wire rope) to absorb energy through tensile deformation during horizontal displacement of the bridge under earthquakes or strong winds, reducing the bridge's vibration amplitude. The relaxed first and second semi-circular rings gradually straighten under stress, providing a damping effect. The relaxed first and second semi-circular rings have a longer energy-dissipating stroke compared to the locked state, resulting in better vibration reduction. Meanwhile, even if the first and second semicircular rings have different lengths due to installation errors, they can automatically coordinate and adapt when under stress, and will not cause uneven stress due to uneven lengths. Therefore, the wire rope is less likely to break gradually. When the horizontal displacement of the bridge exceeds a certain limit, the wire rope system will limit the relative displacement of the upper and lower seat plates to prevent the bridge from falling off the support.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example
[0031] A damping type anti-fall beam vibration reduction bearing includes an upper bearing plate 1, a lower bearing plate 2, and a bearing core 8 located between the upper bearing plate 1 and the lower bearing plate 2. A steel wire rope located outside the bearing core 8 is wound between the upper bearing plate 1 and the lower bearing plate 2. The steel wire rope includes a first steel wire rope 3, a second steel wire rope 4, and a transition steel wire rope. The first steel wire rope 3 is located outside the second steel wire rope 4, and the second steel wire rope 4 is located outside the bearing core 8. The first steel wire rope 3 and the second steel wire rope 4 respectively form a plurality of relaxed first semicircular rings 301 and second semicircular rings 401 distributed between the upper bearing plate 1 and the lower bearing plate 2. The first semicircular rings 301 and second semicircular rings 401 are arranged opposite to each other. The transition steel wire rope connects adjacent first semicircular rings 301 and adjacent second semicircular rings 401.
[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the upper support plate 1 is connected to the superstructure (beam), the lower support plate 2 is connected to the substructure of the bridge (such as the pier), and the support core 8 is located between the upper support plate 1 and the lower support plate 2, bearing the vertical load of the bridge.
[0033] The first wire rope 3 is located outside the second wire rope 4. After bending outward, the first wire rope 3 forms multiple relaxed first semicircular rings 301. The multiple first semicircular rings 301 are distributed in a ring shape between the upper seat plate 1 and the lower seat plate 2. Under the action of earthquakes or strong winds, the first wire rope 3 absorbs energy through tensile deformation, restricts the relative displacement of the upper seat plate 1 and the lower seat plate 2, and prevents the beam from falling. The second wire rope 4 is located outside the support core 8 and inside the first wire rope 3. After bending inward, the second wire rope 4 forms multiple relaxed second semicircular rings 401. The second semicircular rings 401 are arranged opposite to the first semicircular rings 301. The second wire rope 4 and the first wire rope 3 work together to provide shock absorption and anti-falling beam functions, and enhance the overall stability of the support. The transition wire rope connects the adjacent first semicircular rings 301 and the adjacent second semicircular rings 401 to ensure the integrity and continuity of the wire rope system, so that the first wire rope 3 and the second wire rope 4 can work together to absorb energy and limit displacement.
[0034] Under the influence of earthquakes or strong winds, bridges will experience horizontal displacement. The wire rope system (including the first wire rope 3, the second wire rope 4, and the transition wire rope) absorbs energy through tensile deformation, reducing the vibration amplitude of the bridge. The relaxed first semicircular ring 301 and the second semicircular ring 401 gradually straighten under stress, providing a damping effect. The relaxed first semicircular ring 301 and the second semicircular ring 401 have a longer energy-dissipating stroke compared to the locked state, resulting in better vibration reduction. At the same time, even if the lengths of the first semicircular ring 301 and the second semicircular ring 401 are different due to installation errors, the semicircular rings can automatically coordinate and adapt under stress, preventing uneven stress due to uneven lengths. Therefore, the wire ropes are less prone to gradual breakage. When the horizontal displacement of the bridge exceeds a certain limit, the wire rope system will limit the relative displacement of the upper bearing plate 1 and the lower bearing plate 2, preventing the bridge from falling off the supports.
[0035] Furthermore, the transition wire rope includes a first transition wire rope 9 and a second transition wire rope 10. The first transition wire rope 9 is located above the second transition wire rope 10. The first transition wire rope 9 connects the upper ends of the adjacent first semicircular ring 301 and the adjacent second semicircular ring 401. The second transition wire rope 10 connects the lower ends of the adjacent first semicircular ring 301 and the adjacent second semicircular ring 401. The first transition wire rope 9 and the second transition wire rope 10 are staggered vertically.
[0036] Specifically, the first transition steel wire is used to connect the upper ends of two adjacent first semicircular rings 301 and the upper ends of two adjacent second semicircular rings 401, and the second transition steel wire rope 10 is used to connect the lower ends of two adjacent first semicircular rings 301 and the lower ends of two adjacent second semicircular rings 401. The first transition steel wire rope 9 and the second transition steel wire rope 10 connect multiple first semicircular rings 301 into a whole loop, and the first transition steel wire rope 9 and the second transition steel wire rope 10 connect multiple second semicircular rings 401 into a whole loop. Figure 3 and Figure 4As shown, the first transition steel wire rope 9 and the second transition steel wire rope 10 are staggered vertically. Taking three adjacent first semicircular rings 301 and second semicircular rings 401 as an example, they can be divided into end, middle, and tail sections from left to right. There are two first transition steel wire ropes at the top, and two second transition steel wire ropes 10 at the bottom. One of the upper first transition steel wire ropes 9 connects to the upper end of the first semicircular ring 301 at the end and the first semicircular ring 301 in the middle. The other first transition steel wire rope 9 connects to the upper end of the second semicircular ring 401 at the end and the second semicircular ring 401 in the middle. The two upper first transition steel wire ropes 9 are positioned opposite each other. One of the lower second transition steel wire ropes 10 connects to the lower end of the first semicircular ring 301 in the middle and the first semicircular ring 301 at the tail. The other second transition steel wire rope 10 connects to the lower end of the second semicircular ring 401 in the middle and the second semicircular ring 401 at the tail. The two lower second transition steel wire ropes 10 are also positioned opposite each other. Figure 5 As shown, the first transition wire rope 9 and the second transition wire rope 10 connect all the first semicircular rings 301 into a whole ring in this manner, and connect all the second semicircular rings 401 into a whole ring.
[0037] Furthermore, the first wire rope 3, the first transition wire rope 9, and the second transition wire rope 10 are a single unit, and the second wire rope 4, the first transition wire rope 9, and the second transition wire rope 10 are also a single unit.
[0038] Specifically, the first wire rope 3, the first transition wire rope 9, and the second transition wire rope 10 are actually one wire rope, and the second wire rope 4, the first transition wire rope 9, and the second transition wire rope 10 are also actually one wire rope. That is, the first wire rope 3 and the second wire rope 4 both contain the first transition wire rope 9 and the second transition wire rope 10. It can also be understood that the first transition wire rope 9 and the second transition wire rope 10 are woven together with the first wire rope 3, and the first transition wire rope 9 and the second transition wire rope 10 are also woven together with the second wire rope 4.
[0039] Furthermore, a first retaining ring 6 is provided below the upper seat plate 1, and a second retaining ring 7 corresponding to the first retaining ring 6 is provided above the lower seat plate 2. Multiple sets of limiting devices for restricting the slippage of the transition steel wire rope are provided between the first retaining ring 6 and the upper seat plate 1, and between the second retaining ring 7 and the lower seat plate 2.
[0040] Specifically, the first retaining ring 6 is set below the upper seat plate 1 by a limiting member and is spaced apart from the upper seat plate 1. The second retaining ring 7 is set above the lower seat plate 2 by a limiting member and is spaced apart from the lower seat plate 2. The first retaining ring 6 and the second retaining ring 7 are set opposite to each other. In addition to connecting the two retaining rings, the limiting member is also used to limit the first transition steel wire rope 9 and the second transition steel wire rope 10 to prevent them from slipping off the support. This ensures that the first steel wire rope 3 and the second steel wire rope 4 can effectively reduce vibration and prevent beam falling.
[0041] Furthermore, the limiting component is a limiting bolt 5, which passes through the upper seat plate 1 from top to bottom and connects to the first retaining ring 6, and passes through the lower seat plate 2 from bottom to top and connects to the second retaining ring 7.
[0042] Furthermore, each set of limiting components includes four limiting bolts 5, which form a rectangle and are distributed at the four corners of the rectangle.
[0043] Furthermore, the two limiting bolts 5 distributed circumferentially in the same set of limiting components form a cavity 11 that allows the wire rope to pass through. The upper and lower ends of the first semicircular ring 301 are located in the corresponding cavity 11, and the upper and lower ends of the second semicircular ring 401 are located in the corresponding cavity 11.
[0044] The upper cavity 11 is composed of two limiting bolts 5 distributed circumferentially in the same set of limiting components, an upper seat plate 1, and a first retaining ring 6. The lower cavity 11 is composed of two limiting bolts 5 distributed circumferentially in the same set of limiting components, a lower seat plate 2, and a second retaining ring 7. The cavity 11 is smaller in the middle and larger at both ends. The inner wall of the cavity 11 is an arc-shaped surface protruding towards the center of the cavity 11. The arc-shaped surface is composed of the sidewalls of the limiting bolts 5.
[0045] Specifically, such as Figure 6 As shown, the cavity 11 is mainly used for the steel wire ropes that form the first semicircular ring 301 and the second semicircular ring 302 to pass through. When the steel wire rope passes through and bends, it contacts the arc-shaped surface. The arc-shaped contact surface increases the radius of curvature of the contact area, which disperses the pressure on the steel wire rope to a larger area and avoids local compression deformation caused by sharp edges. When the steel wire rope bends, the internal steel wires will generate alternating stress. The arc-shaped contact surface can reduce the relative slippage and friction between the steel wires and reduce the risk of fatigue fracture.
[0046] Furthermore, the two limiting bolts 5 distributed circumferentially on the inner side of the two adjacent sets of limiting members restrict the first transition steel wire rope 9 and the second transition steel wire rope 10 from sliding out. The first transition steel wire rope 9 and the second transition steel wire rope 10 are located inside the two limiting bolts 5 on the inner side.
[0047] Specifically, such as Figure 3 and Figure 4As shown, multiple sets of limiting components are arranged in a ring on the outside of the support core 8. Each set of limiting components consists of four limiting bolts 5, which form a rectangle. The four limiting bolts 5 are located at the four corners of the rectangle. The limiting components are distributed vertically. A cavity 11 is formed between two limiting bolts 5 distributed along the circumferential direction in the same set of limiting components. The cavity 11 is through which the first wire rope 3 or the second wire rope 4 passes. The two limiting bolts 5 on the inner side of the adjacent sets of limiting components distributed along the circumferential direction are used to restrict the first transition wire rope 9 or the second transition wire rope 10 from sliding off the support, thus acting as a baffle. This embodiment uses the threading of the first steel wire rope 3 as an example. The threading method of the first steel wire rope 3 and the second steel wire rope 4 is the same. One end of the first steel wire rope 3 is inserted into the cavity 11 above and then bent to form the first transition steel wire rope 9. Then it is inserted outward from the adjacent cavity 11 above. At this time, the first transition steel wire rope 9 is restricted to the two limiting bolts 5 on the inner side of the two adjacent sets of limiting members. After the first steel wire rope 3 is inserted, it is bent directly downward to form the first semi-circular ring 301. Then it is inserted into the corresponding cavity 11 below and bent again to form the second transition steel wire rope 10. Then it is inserted out of the adjacent cavity 11 below and bent upward to form another first semi-circular ring 301. Then it is inserted again from the corresponding cavity 11 above. After one cycle, one end of the first steel wire rope 3 is connected to the other end to form an integral ring. The connection method of the steel wire rope is the prior art. The aluminum alloy pressing joint connection method or the rope clamp connection method can be used.
[0048] Furthermore, the support core 8 can be any one of a rubber support, a spherical support, a friction pendulum support, or a vibration damping and isolation support.
[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
