Description

Technical Field

[0001] This invention belongs to the field of bridge vibration reduction technology, and particularly relates to a cable-stayed spherical bearing with a shear-resistant transition steel plate structure. Background Technology

[0002] Spherical bearings are a new type of bridge bearing developed based on pot bearings. With advantages such as reliable force transmission, uniform force distribution, and flexible displacement, spherical bearings are a structural form suitable for multi-directional displacement functions. Spherical bearings not only have the characteristics of strong load-bearing capacity and large horizontal displacement of pot bearings, but can also be applied to various bridge structures such as wide bridges, sloping bridges, and curved bridges. According to their performance, spherical bearings are roughly divided into two-way movable bearings, one-way movable bearings, and fixed bearings, while one-way sliding spherical bearings have vertical load-bearing and unidirectional sliding performance.

[0003] When existing unidirectional sliding spherical bearings support bridges, the shear force generated by the slight relative sliding between the upper and lower bearings during bridge vibrations is resisted by the shear shaft. After too many vibrations, the shear shaft will deform, reducing its effectiveness in resisting shear forces and making it prone to breakage. This results in the spherical bearing itself being the sole countermeasure for minor bridge vibrations, reducing its service life. Furthermore, the shear shaft of existing spherical bearings may break during severe bridge vibrations. Although the tension force generated by the cables can provide some buffering, the shear shaft will be irreversibly damaged after the vibration ends, requiring replacement of the shear shaft or even the entire spherical bearing. Summary of the Invention

The two sets of load-bearing mechanisms are symmetrically arranged on both sides of the shear shaft.

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

[0024] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-5 This invention provides a cable-stayed spherical support with a shear-resistant transition steel plate structure, comprising a lower support 2, an intermediate arc plate 7 slidably disposed on the top of the lower support 2, and an upper support 1 slidably connected to the top of the intermediate arc plate 7.

[0026] Two sets of shear shafts 4 are slidably arranged between the lower support 2 and the upper support 1. Two sets of load-bearing mechanisms are respectively arranged between the two ends of the shear shaft 4 and the lower support 2 and the upper support 1. The two sets of load-bearing mechanisms are symmetrically arranged on both sides of the shear shaft 4. The load-bearing mechanisms are used to transmit the micro vibration force between the shear shaft 4 and the lower support 2 and the upper support 1. The two sets of load-bearing mechanisms are connected to a buffer mechanism through two sets of on / off control components. The buffer mechanism is used to control the connection or disconnection of hydraulic oil between the load-bearing mechanism and the buffer mechanism.

[0027] Two sets of cable assemblies are provided between the lower support 2 and the upper support 1. The two sets of cable assemblies are used to counteract the violent vibration force between the lower support 2 and the upper support 1. The on / off control component is connected to the cable assembly. When the cable assembly is under tension, the on / off control component is in the connected state. When the cable assembly is not under tension, the on / off control component is in the disconnected state.

[0028] The main function of the shear shaft 4 is to counteract the micro-vibration force between the upper support 1 and the lower support 2 through deformation. The main function of the load-bearing mechanism is to assist the shear shaft 4 in counteracting the micro-vibration force between the upper support 1 and the lower support 2 through its own energy absorption. The main function of the buffer mechanism is to unload the excessive vibration force on the shear shaft 4 when severe vibration occurs, to prevent the shear shaft 4 from breaking and to maintain the shear shaft 4's ability to counteract vibration. The main function of the on / off control component is to ensure that the buffer mechanism only functions when severe vibration occurs. The main function of the cable assembly is to counteract the vibration force between the upper support 1 and the lower support 2 when severe vibration occurs, and the cable assembly can control the on / off control component when it is in operation, so that the buffer mechanism can function. Overall, this invention sets up a load-bearing mechanism, which, together with the shear shaft, counteracts the micro-vibration force to prevent the shear shaft from undergoing permanent deformation after resisting micro-vibration for a long time. In the event of severe vibration, it automatically unloads the excessive shear force on the shear shaft to prevent damage to the shear shaft and maintain the energy dissipation function of the shear shaft.

[0029] In a further optimized design, the top of the lower support 2 is fixedly connected to the intermediate support 6, and the intermediate arc plate 7 is slidably connected to the top of the intermediate support 6.

[0030] The scheme is further optimized. The load-bearing mechanism between the upper support 1 and the shear shaft 4 includes an active hydraulic chamber 10 opened in the upper support 1. An active piston 9 is slidably connected in the active hydraulic chamber 10. A connecting rod 8 is fixedly connected between the active piston 9 and the shear shaft 4 on the side of the active piston 9 close to the shear shaft 4. The end of the active hydraulic chamber 10 away from the shear shaft 4 is connected to the buffer mechanism.

[0031] The load-bearing mechanisms are configured with the same structure in both the upper support 1 and the lower support 2. For example... Figure 2 and Figure 4 As shown, two sets of active pistons 9 are symmetrically arranged at the top of the outer shear shaft 4. When a minor lateral vibration occurs between the upper support 1 and the shear shaft 4, the active pistons 9 slide within the active hydraulic chamber 10. Because the on / off control component obstructs the flow of hydraulic oil within the active hydraulic chamber 10, the movement of the active pistons 9 is subject to significant resistance, thus generating considerable resistance to the relative displacement between the upper support 1 and the shear shaft 4. Simultaneously, the active pistons 9 within the lower support 2 generate significant resistance to the movement between the lower support 2 and the shear shaft 4. Combined with the deformation resistance of the shear shaft 4 itself, this counteracts the relative slippage between the upper support 1 and the lower support 2, effectively mitigating the minor vibration force between them and reducing the working load on the shear shaft 4. The working principle of the inner shear shaft 4 and the active pistons 9 is the same.

[0032] In a further optimized design, the buffer mechanism inside the upper support 1 includes a passive hydraulic chamber 17 opened inside the upper support 1. A passive piston 15 is slidably connected inside the passive hydraulic chamber 17. A second spring 16 abuts between one side of the passive piston 15 and the passive hydraulic chamber 17. The end of the passive hydraulic chamber 17 away from the second spring 16 is connected to the active hydraulic chamber 10.

[0033] In a further optimized design, a connecting channel 11 is provided inside the upper support 1, and the end of the passive hydraulic chamber 17 away from the second spring 16 is connected to the end of the active hydraulic chamber 10 away from the shear axis 4 through the connecting channel 11.

[0034] like Figure 2 and Figure 4 As shown, when severe vibration occurs, the two sets of on / off control components on the outer side connect the two sets of passive hydraulic chambers 17 to the two sets of active hydraulic chambers 10 through the two sets of connecting channels 11. At this time, the hydraulic oil in the active hydraulic chamber 10 is connected to the hydraulic oil in the passive hydraulic chamber 17. The active piston 9 pushes the hydraulic oil to pressurize the passive piston 15, causing the passive piston 15 to move within the passive hydraulic chamber 17 and compress the second spring 16. Although the active piston 9 can still apply a thrust to the shear shaft 4, the thrust applied to the shear shaft 4 will not be too large because the active piston 9 can continue to move towards the connecting channel 11, thus preventing the shear shaft 4 from continuing to deform and thus avoiding breakage during severe vibration. At the same time, since the second spring 16 and the passive piston 15 can still generate resistance to the sliding of the active piston 9 through the hydraulic oil, the shear shaft 4 can still generate resistance to the sliding between the upper support 1 and the lower support 2 through the active piston 9 during severe vibration, which plays an auxiliary role in counteracting the vibration force of the cable assembly.

[0035] In a further optimized design, the cable assembly includes sliding cavities 21 respectively opened in the upper support 1 and the lower support 2. The two sets of sliding cavities 21 are respectively located on the sides of the upper support 1 and the lower support 2, and the two sets of sliding cavities 21 are located on the same side. Connecting plates 18 are slidably connected in the two sets of sliding cavities 21. Several cables 3 are fixedly connected between the side walls of the two sets of connecting plates 18 away from the shear axis 4. The cables 3 slide through the side walls of the two sets of sliding cavities 21. Several third springs 20 are abutted between the side of the connecting plate 18 near the cables 3 and the sliding cavity 21.

[0036] like Figure 1 , Figure 2 and Figure 4As shown, when severe vibration occurs, a large relative displacement occurs between the upper support 1 and the lower support 2. At this time, several cables 3 are stretched. Under the combined stretching action of the cables 3, the connecting plates 18 located in the upper support 1 and the lower support 2 are pulled away from the shear axis 4. Simultaneously, the connecting plates 18 compress the third spring 20. When the connecting plates 18 are in contact with the side wall of the sliding cavity 21, the connecting plates 18 can no longer move. At this time, the cables 3 can no longer slide relative to the upper support 1 and the lower support 2. The cables 3 restrict the relative movement between the upper support 1 and the lower support 2, thereby counteracting the vibration force. After the severe vibration force disappears, the third spring 20 pushes the connecting plates 18 back to their initial position towards the shear axis 4.

[0037] The scheme is further optimized. The on / off control component in the upper support 1 includes a stop cavity 23 opened in the upper support 1. The stop cavity 23 penetrates the side wall of the connecting channel 11. A stop rod 12 is slidably connected in the stop cavity 23. A steel wire rope 14 is connected between the end of the stop rod 12 near the connecting plate 18 and the connecting plate 18. A first spring 13 abuts between the end of the stop rod 12 near the connecting plate 18 and the stop cavity 23. A flow hole 24 is opened on the stop rod 12. The flow hole 24 is used to connect the active hydraulic chamber 10 and the passive hydraulic chamber 17.

[0038] like Figures 2-4 As shown, when only minor vibrations occur, the stop rod 12, pushed by the spring force of the first spring 13, adheres tightly to the end of the stop cavity 23 away from the connecting plate 18. At this time, the flow hole 24 corresponds to the side wall of the stop cavity 23, and the hydraulic oil in the active hydraulic cavity 10 cannot flow into the passive hydraulic cavity 17 through the stop rod 12 in the connecting channel 11, thus causing greater resistance to the movement of the active piston 9. When severe vibrations occur, several cables 3 pull the connecting plate 18 away from the shear shaft 4. While the connecting plate 18 moves in the sliding cavity 21, it pulls the stop rod 12 through the wire rope 14 to squeeze the first spring 13, causing the stop rod 12 to move towards the connecting plate 18, so that the flow hole 24 connects with the connecting channel 11. At this time, the hydraulic oil in the active hydraulic cavity 10 can flow into the passive hydraulic cavity 17 through the flow hole 24, thereby reducing the movement resistance of the active piston 9 and achieving the effect of unloading the excessive vibration force on the shear shaft 4.

[0039] In a further optimized design, a number of stop blocks 19 are fixedly connected to the side of the sliding cavity 21 away from the shear shaft 4. The connecting plate 18 is correspondingly set with the number of stop blocks 19. The side wall of the number of stop blocks 19 near the connecting plate 18 is provided with spring holes 22. A number of third springs 20 are respectively set in the number of spring holes 22.

[0040] like Figure 2 and Figure 4As shown, the main function of the stop block 19 is to block the movement of the connecting plate 18. When a violent vibration occurs, it can quickly stop the connecting plate 18, so that the several cables 3 can quickly counteract the vibration force.

[0041] In a further optimized design, grooves 5 are provided on the upper support 1 and the lower support 2 respectively. The grooves 5 are used to allow the shear shaft 4 to pass through the upper support 1 or the lower support 2. Stops 25 are provided on both sides of the grooves 5 respectively. When the shear shaft 4 moves to the edge of the groove 5, the stops 25 are used to support the shear shaft 4.

[0042] In a further optimized design, a reinforcing plate 26 is fixedly connected between the side of the stop block 25 away from the shear axis 4 and the upper support 1 and the lower support 2.

[0043] like Figure 1 As shown, the main function of the groove 5 is to limit the movement direction of the shear shaft 4 relative to the upper support 1 and the lower support 2. By setting the stop 25, when distance vibration occurs, the sliding distance of the shear shaft 4 in the groove 5 also increases because the active piston 9 can continue to slide. When the shear shaft 4 is in contact with the stop 25, the shear shaft 4 no longer moves. At this time, since the side wall of the stop 25 can support the shear shaft 4, the part of the shear shaft 4 that bears the shear force in the air (i.e., the part of the shear shaft 4 between the stop 25 on the upper support 1 and the stop 25 on the opposite side of the lower support 2) is reduced. By reducing the cantilever length of the shear shaft 4, the shear force borne by the shear shaft 4 is reduced, and the ability of the shear shaft 4 to cancel the vibration force between the upper support 1 and the lower support 2 is improved.

[0044] The working process of this embodiment is as follows: When a micro-vibration occurs, several cables 3 remain in a slack state. At this time, the stop rod 12, under the elastic force of the first spring 13, is tightly attached to the end of the stop cavity 23 near the shear shaft 4, and the flow hole 24 is not connected to the connecting channel 11. Relative movement occurs between the upper support 1 and the lower support 2. The active piston 9 moves within the active hydraulic chamber 10 under the action of the shear shaft 4. Due to the resistance of the hydraulic oil in the active hydraulic chamber 10, the movement of the active piston 9 is subject to significant resistance. Combined with the deformation resistance of the shear shaft 4 itself, this generates resistance to the relative sliding between the upper support 1 and the lower support 2, thereby counteracting the vibration force.

[0045] When severe vibration occurs, the relative slippage between the upper support 1 and the lower support 2 increases. Several cables 3 are straightened and pull the connecting plate 18 to abut against the stop block 19. By limiting the displacement of the connecting plate 18, the cables 3 generate resistance to the lateral slippage between the upper support 1 and the lower support 2. At the same time, the connecting plate 18 pulls the stop rod 12 to connect the flow hole 24 with the connecting channel 11, allowing the hydraulic oil in the active hydraulic chamber 10 to flow into the passive hydraulic chamber 17. The active piston 9 can continue to move, pushing the passive piston 15 to squeeze the second spring 16 through the hydraulic oil. By reducing the movement resistance of the active piston 9 and increasing the movement distance of the active piston 9, the excessive shear force on the shear shaft 4 is relieved, preventing the shear shaft 4 from breaking during severe vibration. Meanwhile, the second spring 16 can still generate resistance to the movement of the active piston 9 through the passive piston 15 and the hydraulic oil, so that the shear shaft 4 can still play a role in counteracting the vibration force during severe vibration.

[0046] After the vibration force disappears, the connecting plate 18 resets under the elastic force of the third spring 20, the tension on the stop rod 12 disappears, and the stop rod 12 resets under the elastic force of the first spring 13, disconnecting the connection between the active hydraulic chamber 10 and the passive hydraulic chamber 17 again, so that the spherical support as a whole returns to its initial state.
