Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge and building seismic resistance technology, specifically to a non-fixed steel wire rope shock absorber. 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 categorized into pot bearings, spherical 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 technologies primarily employ fixed steel wire ropes at the top and bottom of supports to achieve vibration damping and prevent beam collapse. However, these wire ropes are typically secured with rope clamps, resulting in a taut, spiral shape. The taut wire rope has a short energy-absorbing stroke, leading to poor energy dissipation. Furthermore, the spiral-shaped wire rope is essentially composed of multiple turns. Due to installation errors, the lengths of these turns can vary. Under stress, this uneven distribution of force causes the shortest turns to bear the load first, followed by the longer ones. This prevents the turns from automatically coordinating and adapting, increasing the risk of gradual breakage. Utility Model Content
[0005] The purpose of this utility model is to provide a non-fixed wire rope vibration damping support. The wire rope is in a slack state after being wound, which increases the energy dissipation stroke of the wire rope and improves the energy dissipation effect. At the same time, each coil of wire rope can automatically coordinate and adapt, avoiding the risk of gradual breakage caused by the different lengths of each coil of wire rope.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:
[0007] A non-fixed wire rope vibration damping support includes a support body, an upper support plate at the upper end and a lower support plate at the lower end. Both the upper and lower support plates have extensions on their sides. A wire rope is wound between the upper and lower extensions. The wire rope is distributed in a ring-shaped spiral on the outside of the support body. The wire rope is in a relaxed state that allows it to slide relative to the extensions. A limiting member is provided at the end of the wire rope.
[0008] In this design, the upper bearing plate is located at the top of the support body and is in direct contact with the superstructure, transferring the load of the superstructure to the support body. Its side has an extension to provide support for the installation and arrangement of the wire rope. The lower bearing plate is located at the bottom of the support body and is connected to the foundation, transferring the load borne by the support body to the foundation. Similarly, its side also has an extension. The wire rope is wound between the extensions of the upper and lower bearing plates, distributed in a spiral shape on the outside of the support body, and positioned at the end of the wire rope. Its main function is to prevent the wire rope from falling off the extension, ensuring that the wire rope is always in the correct installation position, and ensuring the stability and reliability of the vibration damping support.
[0009] Initial relaxation state: Under normal load, since the wire rope is in a relaxed state, it does not directly participate in bearing the load of the superstructure. At this time, the support body mainly bears the pressure transmitted by the superstructure. Its working principle is similar to that of traditional supports, which uniformly transmit the load to the lower foundation through its own structural characteristics.
[0010] Earthquake or impact load: When an earthquake or impact load occurs, the superstructure will experience significant horizontal displacement and vertical vibration. Since the wire rope can slide relative to its extension, it will gradually tighten as the superstructure displaces. The elastic properties of the wire rope allow it to absorb and dissipate some energy, thereby reducing the vibration amplitude of the superstructure and playing a role in shock absorption.
[0011] Energy dissipation: During the stretching process, the wire rope undergoes elastic deformation. At the same time, the friction between the wire ropes and the friction between the wire rope and the extension also consumes some energy. This energy dissipation helps to reduce the dynamic response of the structure and protect the superstructure from damage by earthquakes or impact loads.
[0012] The wire rope and its extension can slide relative to each other, and the wire rope is in a slack state. When relative displacement occurs, the wire rope will be gradually tightened. As the displacement increases, the wire rope begins to undergo elastic and plastic deformation. Energy is dissipated through the friction and deformation of the wire rope, thereby reducing the load on the support and playing a role in shock absorption and buffering. At the same time, the individual turns of the spiral wire rope are not locked and are in a slack state. In this way, the individual turns of the wire rope can automatically coordinate and adapt, avoiding the risk of uneven stress and gradual breakage caused by the different lengths of the individual turns of the wire rope.
[0013] Optionally, the extension is a mounting plate with multiple mounting holes. The mounting holes are evenly distributed in a ring on the outside of the support body. The diameter of the mounting holes is larger than the diameter of the wire rope and smaller than the size of the limiting member. The wire rope passes through the upper and lower mounting holes one after another and is distributed in a ring-like spiral on the outside of the support body.
[0014] Optionally, the extension consists of two bolts, with a mounting hole between the two bolts allowing the wire rope to pass through. The diameter of the mounting hole is smaller than the size of the limiting member, and the distance between the bolt heads is smaller than the diameter of the wire rope.
[0015] Optionally, the assembly hole is larger at both ends and smaller in the middle, and the inner wall of the assembly hole is an arc-shaped surface that protrudes towards the centerline of the assembly hole. The arc-shaped surface is formed by the side wall of the bolt shank, and the wire rope is tangent to the arc-shaped surface when it passes through the assembly hole.
[0016] Optionally, the limiting component is a limiting nut, with the end of the wire rope connected to the limiting nut, and the diameter of the limiting nut being larger than the diameter of the mounting hole and assembly hole.
[0017] Optionally, the limiting nut at one end of the wire rope is located on the bottom surface of the upper seat plate, and the limiting nut at the other end is located on the top surface of the lower seat plate.
[0018] Optionally, the wire rope is an integral loop spiral or a multi-segment spiral wound around the outside of the support body.
[0019] Optionally, the wire rope is a ring-shaped spiral structure formed by winding multiple strands of wire rope.
[0020] Optionally, the mounting plate is integrally formed with the upper seat plate and the lower seat plate or connected by bolts or welding.
[0021] Optionally, the support body can be any one of a rubber support, a ball bearing, a friction pendulum support, or a seismic isolation support.
[0022] The beneficial effects of this utility model are:
[0023] In existing technologies, wire ropes are primarily secured using rope clamps. The secured wire rope forms a taut, spiral shape, which limits its energy-absorbing stroke and results in poor energy dissipation. Furthermore, the spiral shape, with multiple turns of wire rope, can lead to uneven stress distribution due to installation errors. The shorter turns bear the load initially, followed by the longer ones, and the inability of the turns to automatically coordinate their stress increases the risk of gradual breakage.
[0024] In this invention, when the support is subjected to an external load, the support body, upper plate, and lower plate will experience relative displacement. Since the wire rope is in a slack state, it will gradually tighten as the relative displacement occurs. As the displacement increases, the wire rope begins to undergo elastic and plastic deformation, dissipating energy through friction and deformation, thereby reducing the load on the support and providing shock absorption and buffering. Simultaneously, because each coil of wire rope is not locked and remains slack, the spiral-shaped coils can automatically coordinate and adapt, avoiding the risk of uneven stress and gradual breakage due to varying lengths.

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
[0035] A non-fixed wire rope vibration damping support includes a support body 1, an upper support plate 2 at the upper end and a lower support plate 3 at the lower end. Both the upper support plate 2 and the lower support plate 3 have extensions on their sides. A wire rope 7 is wound between the upper extension and the lower extension. The wire rope 7 is distributed in a ring-shaped spiral on the outside of the support body 1. The wire rope 7 is in a relaxed state that can slide relative to the extension. A limiting member 6 is provided at the end of the wire rope 7.
[0036] In this embodiment, as Figure 1 As shown, the upper support plate 2 is located at the upper end of the support body 1 and is in direct contact with the superstructure (generally a beam), transferring the load of the superstructure to the support body 1. Its side has an extension to provide support for the installation and arrangement of the wire rope 7. The lower support plate 3 is located at the lower end of the support body 1 and is connected to the lower foundation (generally a pier), transferring the load borne by the support body 1 to the foundation. Similarly, its side also has an extension. The wire rope 7 is wound between the extensions of the upper support plate 2 and the lower support plate 3, as shown... Figure 2 As shown, the wire rope 7 is arranged in a spiral shape on the outside of the support body 1 and is located at the end of the wire rope 7. Its main function is to prevent the wire rope 7 from falling off the extension and to ensure that the wire rope 7 is always in the correct installation position, thereby ensuring the stability and reliability of the shock absorber support.
[0037] Initial relaxation state: Under normal load, since the wire rope 7 is in a relaxed state, it does not directly participate in bearing the load of the superstructure. At this time, the support body 1 mainly bears the pressure transmitted by the superstructure. Its working principle is similar to that of a traditional support, which transmits the load evenly to the lower foundation through its own structural characteristics.
[0038] Earthquake or impact load: When an earthquake or impact load occurs, the superstructure will experience significant horizontal displacement and vertical vibration. Since the wire rope 7 can slide relative to the extension, it will gradually be tightened as the superstructure displaces. The elastic properties of the wire rope 7 allow it to absorb and dissipate some energy, thereby reducing the vibration amplitude of the superstructure and playing a role in shock absorption.
[0039] Energy dissipation: During the stretching process, the wire rope 7 undergoes elastic deformation. At the same time, the friction between the wire ropes 7 and the friction between the wire rope 7 and the extension also consumes some energy. This energy dissipation helps to reduce the dynamic response of the structure and protect the superstructure from damage by earthquakes or impact loads.
[0040] The wire rope 7 and the extension can slide relative to each other, and the wire rope 7 is in a slack state. When relative displacement occurs, the wire rope 7 will be gradually tightened. As the displacement increases, the wire rope 7 begins to produce elastic deformation and plastic deformation. Energy is dissipated through the friction and deformation of the wire rope 7, thereby reducing the load borne by the support and playing a role in shock absorption and buffering. At the same time, the wire ropes 7 that make up the spiral are not locked and are in a slack state. In this way, the wire ropes 7 can automatically coordinate and adapt, avoiding the risk of uneven stress and gradual breakage caused by the different lengths of the wire ropes 7.
[0041] Furthermore, the extension is a mounting plate 4, on which a plurality of mounting holes 5 are provided. The plurality of mounting holes 5 are evenly distributed in a ring on the outside of the support body 1. The diameter of the mounting holes 5 is larger than the diameter of the wire rope 7 and smaller than the size of the limiting member 6. The wire rope 7 passes through the upper mounting hole 5 and the lower mounting hole 5 in turn and is distributed in a ring-like spiral on the outside of the support body 1.
[0042] Specifically, the mounting plate 4 is an annular plate, fixed to the circumferential ends of the upper seat plate 2 and the lower seat plate 3. Multiple mounting holes 5 are opened on the mounting plate 4, and the multiple mounting holes 5 are evenly distributed in a ring on the outside of the support body 1. The mounting holes 5 at the upper end correspond to the mounting holes 5 at the lower end. This distribution method allows the wire rope 7 to be evenly distributed around the support when it is wound, ensuring that the shock-absorbing support can play a shock-absorbing role in all directions and avoiding uneven shock-absorbing effect.
[0043] The diameter of the mounting hole 5 is larger than the diameter of the wire rope 7. This is to ensure that the wire rope 7 can pass smoothly through the mounting hole 5, and that the wire rope 7 can have a certain amount of room to move within the mounting hole 5 when subjected to earthquake or impact loads, so as to achieve relative sliding with the mounting plate 4 and thus play a shock absorption role. In this way, each coil of wire rope 7 can automatically coordinate and adapt, avoiding the risk of uneven stress and gradual breakage caused by the different lengths of each coil of wire rope 7.
[0044] The diameter of the mounting hole 5 is smaller than the size of the limiting member 6, so the limiting member 6 cannot pass through the mounting hole 5. This effectively prevents the wire rope 7 from falling out of the mounting hole 5, ensuring that the wire rope 7 is always in the correct installation position and ensuring the reliability and safety of the shock absorber support.
[0045] After passing through the upper and lower mounting holes 5 in sequence, the wire rope 7 is distributed in a ring-like spiral shape on the outside of the support body 1. The threading sequence can be from top to bottom or from bottom to top. This winding method increases the length and deformation space of the wire rope 7, allowing the wire rope 7 to produce greater elastic deformation when subjected to load, thereby absorbing more energy and improving the shock absorption effect. The ring-like spiral distribution also allows the wire rope 7 to restrain each other in all directions, forming a whole, which enhances the stability and load-bearing capacity of the wire rope 7.
[0046] Furthermore, the extension consists of two bolts 8, with a mounting hole 10 between the two bolts 8 that allows the wire rope 7 to pass through. The diameter of the mounting hole 10 is smaller than the size of the limiting member 6, and the distance between the bolt heads 9 of the two bolts 8 is smaller than the diameter of the wire rope 7.
[0047] Specifically, such as Figure 4 and Figure 5 As shown, the two bolts 8 form an assembly hole 10 that allows the wire rope 7 to pass through. By utilizing the structural characteristics of the bolts 8, there is no need to process the complex mounting hole 5 structure, which simplifies the manufacturing process of the support. The two bolts 8 are arranged horizontally along the upper seat plate 2 and the lower seat plate 3.
[0048] The diameter of the mounting hole 10 is smaller than the size of the limiting member 6, ensuring that the limiting member 6 cannot pass through the mounting hole 10, thereby preventing the wire rope 7 from falling out between the two bolts 8 and ensuring that the wire rope 7 is always in the correct installation position. The distance between the bolt heads 9 of the two bolts 8 is smaller than the diameter of the wire rope 7. This design allows the wire rope 7 to be effectively clamped after passing through the mounting hole 10, preventing the wire rope 7 from sliding out of the mounting hole 10 radially along the upper seat plate 2 and the lower seat plate 3.
[0049] When installing the wire rope 7, the operator only needs to pass the wire rope 7 through the assembly hole 10 formed between the two bolts 8. However, since the distance between the bolt heads 9 is smaller than the diameter of the wire rope 7, after the limiting member 6 is installed at the end of the wire rope 7, its size is larger than the diameter of the assembly hole 10, which can reliably limit the displacement of the wire rope 7 and ensure the stability of the installation.
[0050] Under earthquake or impact loads, the wire rope 7 can slide relative to the bolt 8, and the wire rope 7 itself will also undergo elastic deformation. While the mounting hole 10 provides some constraint to the wire rope 7, it does not hinder its relative sliding and deformation. The wire rope 7 can effectively absorb and dissipate energy, thus playing a shock-absorbing role. The wire rope 7 can move relative to the bolt 8 within the mounting hole 10, allowing the spiral coils of wire rope 7 to automatically coordinate and adapt, avoiding the risk of uneven stress and gradual breakage due to varying lengths.
[0051] The extension and mounting hole 10 are constructed using only two bolts 8, resulting in a simple structure, low manufacturing cost, and ease of processing and installation. By replacing bolts 8 with different specifications, the size and position of the mounting hole 10 can be changed to accommodate wire ropes 7 of different diameters or different installation requirements, offering a degree of flexibility. Compared to the mounting plate 4 design, the two bolts 8 occupy less space, making it more suitable for installation environments with limited space.
[0052] Furthermore, the assembly hole 10 is larger at both ends and smaller in the middle. The inner wall of the assembly hole 10 has an arc-shaped surface that protrudes towards the centerline of the assembly hole 10. The arc-shaped surface is formed by the side wall of the bolt 8. When the wire rope 7 passes through the assembly hole 10, it is tangent to the arc-shaped surface.
[0053] Specifically, such as Figure 6 As shown, the design of the mounting hole 10, which is larger at both ends and smaller in the middle, resembles a dumbbell or hourglass shape. The bolt 8's sidewall forms an arc-shaped surface that bulges towards the centerline of the mounting hole 10, giving the inner wall of the mounting hole 10 a smooth, curved profile. When the wire rope is bent and wound, the arc-shaped contact surface increases the radius of curvature of the contact area, distributing the pressure on the wire rope over a larger area and avoiding localized compression deformation caused by sharp edges. Analogous: When pressing a balloon with a finger, if the contact surface is arc-shaped (like the fingertip), the balloon's surface deforms evenly; if it's a sharp object (like a pen tip), the balloon will burst quickly. When the wire rope is bent, the internal wires generate alternating stress. The arc-shaped contact surface reduces the relative slippage and friction between the wires, lowering the risk of fatigue fracture.
[0054] When the wire rope 7 is subjected to earthquake or impact loads, contact stress will be generated in the part that is tangent to the arc surface. Due to the special shape of the arc surface, the contact stress can be evenly distributed along the arc surface, avoiding local stress concentration, thereby reducing the wear and fatigue damage of the wire rope 7.
[0055] Furthermore, the limiting component 6 is a limiting nut, and the end of the wire rope 7 is connected to the limiting nut. The diameter of the limiting nut is larger than the diameter of the mounting hole 5 and the assembly hole 10.
[0056] Specifically, such as Figure 5 As shown, the connection method between the limiting nut and the wire rope 7 is existing technology. Using a specialized crimping tool, the end of the wire rope 7 is placed into a specific crimping area of the limiting nut, and pressure is applied to tightly connect the wire rope 7 to the limiting nut. This connection method is relatively simple to operate, has high connection strength, and ensures that the wire rope 7 and the limiting nut are not easily separated under stress. Alternatively, welding can be used to connect the end of the wire rope 7 to the limiting nut.
[0057] Of course, the limiting component 6 is not only the limiting nut, but can also be an anchor head, a U-shaped buckle, etc. It is necessary to ensure that the limiting component 6 cannot pass through the mounting hole 5 or the assembly hole 10.
[0058] Since the diameter of the limiting nut is larger than the diameter of the mounting hole 5 and the assembly hole 10, after the wire rope 7 passes through the mounting hole 5 or the assembly hole 10, the limiting nut is installed at the end of the wire rope 7. The limiting nut will be stuck on one side of the hole, thereby preventing the wire rope 7 from sliding out of the hole. No matter what direction the wire rope 7 is subjected to tension or impact force, the limiting nut can effectively limit the displacement of the wire rope 7 and ensure that the wire rope 7 is always in the correct installation position.
[0059] Furthermore, the limiting nut at one end of the wire rope 7 is located on the bottom surface of the upper seat plate 2, and the limiting nut at the other end is located on the top surface of the lower seat plate 3.
[0060] like Figure 2 and Figure 3 As shown, the steel wire rope 7 is either an integral loop spiral or a multi-segment spiral wound around the outside of the support body 1.
[0061] Furthermore, the steel wire rope 7 is a ring-shaped spiral structure formed by winding multiple strands of steel wire rope 7.
[0062] Specifically, the winding and forming method of the steel wire rope 7 itself belongs to existing technology.
[0063] Furthermore, the mounting plate 4 is integrally formed with the upper seat plate 2 and the lower seat plate 3, or is connected by bolts 8 or welding.
[0064] Furthermore, the support body 1 can be any one of a rubber support, a ball bearing, a friction pendulum support, or a vibration damping and isolation support.
[0065] 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.
