Description

Technical Field

[0001] This utility model relates to the field of bridge technology, specifically to a shock-absorbing bearing. Background Technology

[0002] In the field of road construction technology, bridges are of paramount importance. Under strong earthquakes, bridges often experience displacement between their upper and lower sections. When this displacement exceeds the limit, the bridge may be damaged. Therefore, bridges are generally equipped with vibration damping bearings to reduce the vibrations they experience.

[0003] For example, the national authorized patent announcement number CN221276312U discloses a bridge vibration damping bearing, including a base plate, a left threaded seat, a right threaded seat, a left connecting rod, a right connecting rod, a top plate, and a support plate. The base plate is rotatably connected to a bidirectional threaded rod. The left threaded seat engages with the left-hand threaded section of the bidirectional threaded rod, and the right threaded seat engages with the right-hand threaded section of the bidirectional threaded rod. The lower end of the left connecting rod is hinged to the left threaded seat, and the lower end of the right connecting rod is hinged to the right threaded seat. The upper ends of both the left and right connecting rods are hinged to the lower surface of the top plate. The upper surface of the top plate is provided with multiple receiving cylinders, and the lower surface of the support plate is provided with multiple vibration damping rubber blocks. The number of vibration damping rubber blocks is equal to the number of receiving cylinders, and each vibration damping rubber block corresponds to one receiving cylinder. The support plate is used to connect the bridge. This application can support bridges of different heights, expanding the applicability of bridge vibration damping bearings.

[0004] However, the aforementioned bridge damping bearings can only provide vertical support and damping in one direction, and cannot effectively resist lateral vibration forces. This can cause the bridge to shift or tilt under lateral forces, affecting the overall stability of the bridge. Utility Model Content

[0005] The purpose of this invention is to provide a shock-absorbing support to solve the problem mentioned in the background art that it can only provide unilateral vertical support and shock absorption, but cannot effectively resist lateral vibration forces.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A shock-absorbing support includes: a lower support column, a cross plate fixedly installed on the upper surface of the lower support column, shock-absorbing mechanisms rotatably installed on the four outer surfaces of the cross plate, an upper support plate rotatably installed on the upper surface of the other end of the four sets of shock-absorbing mechanisms, and a protective sleeve fixedly installed on the lower surface of the upper support plate. The protective sleeve is fitted onto the outer surfaces of the shock-absorbing mechanisms and the lower support column.

[0008] Preferably, a positioning block is fixedly installed on the lower surface of the upper support plate. The positioning block is made of rubber and is damped and slidably inserted into the outer surface of the cross plate.

[0009] Preferably, the shock absorption mechanism includes two sets of connecting arms. Each pair of connecting arms is rotatably mounted on the upper and lower ends of one outer surface of the cross plate. A support rod is rotatably mounted between the other ends of the two sets of connecting arms. A universal ball is fixedly mounted on the upper surface of the support rod. The universal ball is rotatably mounted in a ball groove. The ball groove is fixedly mounted on the four ends of the lower surface of the cross plate.

[0010] Preferably, the outer surfaces of the two sets of connecting arms are respectively rotatably mounted with a first T-shaped post and a second T-shaped post, and the second T-shaped post is damped and slidably mounted inside the first T-shaped post, and is inclined.

[0011] Preferably, springs are fitted onto the outer surfaces of the first T-shaped post and the second T-shaped post, and the two ends of the springs are respectively fixedly connected to one end of the first T-shaped post and the second T-shaped post.

[0012] Preferably, when the upper support plate presses down on the universal ball, the universal ball can drive the support rod to pull the two sets of connecting arms to rotate downward on the outer surface of the cross plate. Since the two sets of connecting arms are arranged vertically, the distance between the two sets of connecting arms will be reduced when they are pressed down and rotated. This allows the two sets of connecting arms to drive the second T-shaped column to slide into the first T-shaped column to compress the spring between them, thus providing a shock absorption effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the upper support plate, shielding cylinder, ball groove, lower support column, and damping mechanism, when the upper support plate is subjected to vertical or lateral vibration force, the upper support plate can press against the four sets of damping mechanisms on the upper surface of the lower support column through the four sets of ball grooves on the lower surface to perform damping operation. If it is lateral vibration force, the upper support plate can perform tilting and rotation damping operation on the outer surface of the damping mechanism through the ball groove, thereby enabling the upper support plate to adapt to vibration force in different directions and improving the overall damping effect. This rotational damping method can better conform to the direction of lateral force and effectively disperse and buffer lateral vibration force. Compared with the support that can only perform vertical damping, it can more accurately deal with lateral vibration force and reduce the impact of lateral vibration on the bridge structure. After the upper support plate is subjected to vibration pressure, it will drive the shielding cylinder on the lower surface to move down together, so that the shielding cylinder is always fitted on the outer surface of the damping mechanism.

[0015] 2. Through the design of the connecting arms, the first T-shaped column, the second T-shaped column, the spring, and the universal ball joint, when the upper support plate is subjected to vibration, the upper support plate can press down on the outer surface of the universal ball joint through the ball grooves at the four ends of the lower surface. This allows the four sets of universal balls to drive the support rods on the lower surface to pull the two sets of connecting arms to rotate downwards on the outer surface of the cross plate. Since the two sets of connecting arms are arranged vertically, the distance between them will decrease when the two sets of connecting arms are pressed down and rotated. This allows the two sets of connecting arms to drive the second T-shaped column to slide into the first T-shaped column, compressing the spring between them to achieve shock absorption. If the upper support plate is subjected to lateral vibration force, it can rotate and tilt on the outer surface of the universal ball through the ball groove on the lower surface, thereby compressing the tilting spring for shock absorption. At the same time, the upper support plate will lift the universal ball on the other side through the ball groove to pull the spring. This method can adaptively adjust in the direction of the lateral force. This adaptive capability can dynamically adjust the state of each component during the shock absorption process, such as the degree of compression and lifting of the spring, according to the magnitude and direction of the lateral force, so as to more accurately disperse and buffer the lateral vibration force and improve the shock absorption efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3As shown, this embodiment provides a shock-absorbing support, including: a lower support column 2, a cross plate 201 fixedly installed on the upper surface of the lower support column 2, shock-absorbing mechanisms 3 rotatably installed on the four outer surfaces of the cross plate 201, an upper support plate 1 rotatably installed on the upper surface of the other end of the four sets of shock-absorbing mechanisms 3, a protective sleeve 101 fixedly installed on the lower surface of the upper support plate 1, the protective sleeve 101 is fitted on the outer surface of the shock-absorbing mechanism 3 and the lower support column 2, and a positioning block 103 fixedly installed on the lower surface of the upper support plate 1. The positioning block 103 is made of rubber and is damped and slidably inserted into the outer surface of the cross plate 201.

[0023] Through the design of the upper support plate 1, the protective cylinder 101, the ball groove 102, the lower support column 2, and the damping mechanism 3, when the upper support plate 1 is subjected to vertical or lateral vibration force, the upper support plate 1 can press against the four sets of damping mechanisms 3 on the upper surface of the lower support column 2 through the four sets of ball grooves 102 on the lower surface to perform damping operation. If the lateral vibration force is used, the upper support plate 1 can perform a damping operation by rotating at an inclination on the outer surface of the damping mechanism 3 through the ball grooves 102. This allows the upper support plate 1 to adapt to vibration forces in different directions, improving the overall damping effect. This rotational damping method can better adapt to the direction of lateral force and effectively disperse and buffer lateral vibration force. Compared with the support that can only perform vertical damping, it can more accurately deal with lateral vibration force and reduce the impact of lateral vibration on the bridge structure. After the upper support plate 1 is subjected to vibration pressure, it will move the protective cylinder 101 on the lower surface together, so that the protective cylinder 101 is always fitted on the outer surface of the damping mechanism 3.

[0024] like Figure 4 As shown, the shock absorption mechanism 3 includes two sets of connecting arms 301. Each pair of connecting arms 301 is rotatably mounted on the upper and lower ends of one outer surface of the cross plate 201. A support rod 305 is rotatably mounted between the other ends of the two sets of connecting arms 301. A universal ball 306 is fixedly mounted on the upper surface of the support rod 305. The universal ball 306 is rotatably mounted in the ball groove 102. The ball groove 102 is fixedly mounted on the four ends of the lower surface of the cross plate 201.

[0025] Among them, the outer surfaces of the two sets of connecting arms 301 are respectively rotatably mounted with a first T-shaped column 302 and a second T-shaped column 303, and the second T-shaped column 303 is damped and slidably mounted inside the first T-shaped column 302 and is inclined.

[0026] Springs 304 are fitted on the outer surfaces of the first T-shaped post 302 and the second T-shaped post 303, and the two ends of the springs 304 are respectively fixedly connected to one end of the first T-shaped post 302 and the second T-shaped post 303.

[0027] When the upper support plate 1 presses down on the universal ball 306, the universal ball 306 can drive the support rod 305 to pull the two sets of connecting arms 301 to rotate downward on the outer surface of the cross plate 201. Since the two sets of connecting arms 301 are arranged vertically, the distance between the two sets of connecting arms 301 will be reduced when they are pressed down and rotated. This allows the two sets of connecting arms 301 to drive the second T-shaped column 303 to slide into the first T-shaped column 302 to compress the spring 304 between them, thus playing a shock-absorbing role.

[0028] Through the design of the connecting arm 301, the first T-shaped column 302, the second T-shaped column 303, the spring 304, and the universal ball 306, when the upper support plate 1 is subjected to vibration, the upper support plate 1 can press down on the outer surface of the universal ball 306 through the ball grooves 102 at the four ends of the lower surface. This allows the four sets of universal balls 306 to drive the support rods 305 on the lower surface to pull the two sets of connecting arms 301 to rotate downwards on the outer surface of the cross plate 201. Since the two sets of connecting arms 301 are arranged vertically, the distance between them will decrease when the two sets of connecting arms 301 are pressed down and rotated. This allows the two sets of connecting arms 301 to drive the second T-shaped column 303 to slide into the first T-shaped column 302 to squeeze. The spring 304 between the compression points acts as a shock absorber. If the upper support plate 1 is subjected to lateral vibration force, the upper support plate 1 can rotate and tilt on the outer surface of the universal ball 306 through the ball groove 102 on the lower surface, so that the spring 304 in the compression tilt direction can be used for shock absorption. At the same time, the upper support plate 1 will lift the universal ball 306 on the other side through the ball groove 102 to pull the spring 304. This method can adaptively adjust in the direction of lateral force. This adaptive capability can dynamically adjust the state of each component during the shock absorption process, such as the degree of compression and lifting of the spring 304, according to the magnitude and direction of the lateral force, so as to more accurately disperse and buffer the lateral vibration force and improve the shock absorption efficiency.

[0029] Based on the above technical solution, the working steps of this solution are summarized as follows: When the upper support plate 1 is subjected to vibration force, it can press down on the outer surface of the universal ball joint 306 through the ball grooves 102 at the four ends of the lower surface. This allows the four sets of universal balls 306 to drive the support rods 305 on the lower surface to pull the two sets of connecting arms 301 to rotate downwards on the outer surface of the cross plate 201. Since the two sets of connecting arms 301 are arranged vertically, the distance between them will decrease when the two sets of connecting arms 301 are pressed down and rotated. The two sets of connecting arms 301 can drive the second T-shaped column 303 to slide into the first T-shaped column 302 to compress the spring 304 between them to play a shock-absorbing role. If the upper support plate 1 is subjected to lateral vibration force, the upper support plate 1 can rotate and tilt on the outer surface of the universal ball 306 through the ball groove 102 on the lower surface to compress the tilted spring 304 to perform shock absorption. At the same time, the upper support plate 1 will lift the other side of the universal ball 306 through the ball groove 102 to pull the other set of springs 304 to perform shock absorption operation.

[0030] In summary: When the upper support plate 1 is subjected to vibration force, it can adaptively adjust in the direction of vibration. This adaptive capability can dynamically adjust the state of each component during the damping process according to the magnitude and direction of the lateral force, such as the degree of compression and lifting of the spring 304, so as to more accurately disperse and buffer the lateral vibration force and improve the damping efficiency.
