Description

Technical Field

[0001] This utility model relates to the field of spherical bearing technology, and in particular to a damping and shock-absorbing spherical bearing. Background Technology

[0002] In the fields of modern architecture, bridges, and large-scale equipment engineering, spherical bearings, with their ability to achieve multi-directional rotation and high load-bearing capacity, have become key components connecting the superstructure and the substructure. From the ultra-long main beams of cross-sea bridges to super high-rise skyscrapers, from the space trusses of large stadiums to the support systems of high-speed rail tracks, spherical bearings are widely used in various complex engineering scenarios to ensure the normal rotation and displacement requirements of structures under load.

[0003] Existing spherical bearing damping mechanisms are simple in structure, typically equipped with only a single spring or rubber damping element. This single-structure design limits their ability to provide limited damping in the vertical direction. When faced with lateral impacts from earthquakes, side loads from strong winds, or complex vibrations from the operation of large equipment, existing damping structures often struggle to cope, unable to work collaboratively in multiple directions to effectively dissipate energy. This results in excessive horizontal displacement of the superstructure, significantly increasing the risk of structural failure.

[0004] Therefore, it is necessary to develop a damping and shock-absorbing spherical bearing to address the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a damping and shock-absorbing spherical bearing that can achieve shock absorption in both horizontal and vertical directions, thereby improving the shock absorption effect of the bearing under complex conditions such as earthquakes and strong winds.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a damping and shock-absorbing spherical bearing, comprising an upper bearing plate and a lower bearing plate. The top surface of the lower bearing plate has an installation groove, and a spherical crown plate is disposed within the installation groove. The bottom surface of the spherical crown plate is slidably engaged with the bottom surface of the installation groove. A spherical liner plate is slidably connected to the top surface of the spherical crown plate, and the top surface of the spherical liner plate is slidably engaged with the bottom surface of the lower bearing plate. A plurality of disc springs are disposed on the bottom surface of the installation groove, and the bottom surface of the spherical liner plate contacts the top surface of the disc springs. A plurality of buffer components are disposed around the spherical liner plate on the bottom surface of the lower bearing plate.

[0008] Furthermore, a first planar sliding plate is fixedly connected to the bottom surface of the mounting groove, and a first planar steel plate is fixedly connected to the bottom surface of the spherical crown plate. The first planar steel plate is slidably connected to the first planar sliding plate.

[0009] Furthermore, a spherical sliding plate is provided on the top surface of the spherical crown plate, and the bottom surface of the spherical liner plate is slidably connected to the spherical sliding plate.

[0010] Furthermore, a second planar sliding plate is fixedly connected to the top surface of the spherical liner, and a second planar steel plate is fixedly connected to the bottom surface of the lower support plate. The second planar steel plate and the second planar sliding plate are slidably connected.

[0011] Furthermore, the buffer assembly includes a hydraulic cylinder, which is fixedly connected to the bottom surface of the lower support plate. The hydraulic cylinder is filled with silicone oil and a sealing cap is sealed to one end near the spherical liner. A piston head is slidably connected to the inner wall of the hydraulic cylinder. An oil hole is opened through the piston head, and a piston rod is fixedly connected to the piston head. The piston rod passes through the sealing cap and is slidably connected to it. A driving block is fixedly connected to the end of the piston rod away from the piston head, and a reset component is provided between the driving block and the hydraulic cylinder.

[0012] Furthermore, the reset component includes a compression spring, which is sleeved on the outer wall of the piston rod and disposed between the oil cylinder and the drive block.

[0013] Furthermore, the compression spring is fitted with a guide cylinder, the piston rod passes through the guide cylinder near one end of the oil cylinder, the other end of the guide cylinder is open, and the driving block is slidably connected to the inner wall of the guide cylinder; one end of the compression spring is fixedly connected to the bottom surface of the inner side of the guide cylinder, and the other end is fixedly connected to the driving block.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This invention provides vertical elastic support through a disc spring within the mounting slot. The cylinder of the buffer assembly is filled with silicone oil. Utilizing the throttling effect of the oil flowing through the oil holes during the reciprocating motion of the piston head, viscous damping is generated, which dissipates vibration energy.

[0020] The core of this invention is to provide a damping and shock-absorbing spherical bearing that can achieve shock absorption in both horizontal and vertical directions, thereby improving the shock absorption effect of the bearing under complex conditions such as earthquakes and strong winds.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] It is understood that all electrical components mentioned in this article are electrically connected to the main controller and power supply, and all electrical components mentioned in this article are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices. Therefore, this utility model will not explain the control method and circuit connection in detail. At the same time, all parts not described in detail in this utility model are common technologies known to those skilled in the art.

[0024] In one specific embodiment of this utility model, such as Figure 1As shown, the damping spherical bearing mainly consists of an upper support plate 1 and a lower support plate 2. The top surface of the lower support plate 2 has a mounting groove 3, within which a spherical crown plate 4 is installed. The bottom surface of the spherical crown plate 4 slides into the bottom surface of the mounting groove 3, providing a basic structure for the bearing's rotation. A spherical liner plate 5 is slidably connected to the top surface of the spherical crown plate 4, and the top surface of the spherical liner plate 5 slides into the bottom surface of the lower support plate 2, allowing the bearing to rotate flexibly in multiple directions. Several disc springs 6 are installed on the bottom surface of the mounting groove 3. These disc springs are evenly distributed in a ring around the center of the spherical liner plate 5, providing balanced support for the spherical liner plate 5. The bottom surface of the spherical liner plate 5 contacts the top of the disc springs 6, providing cushioning and damping for the bearing in the vertical direction. Several buffer components 7 are installed around the spherical liner plate 5 on the bottom surface of the lower support plate 2 to handle horizontal loads and enhance the stability of the bearing under complex stress conditions.

[0025] It should be noted that the bottom surface of the mounting groove 3 has a cylindrical groove (not shown in the figure) that matches the outer diameter of the disc spring 6. The groove depth is 1 / 3 to 2 / 3 of the free height of the disc spring 6, ensuring accurate positioning of the disc spring 6 and preventing lateral displacement. During installation, the spherical liner 5 applies initial pressure to the disc spring 6, giving it stable support stiffness even under no-load conditions. The disc spring 6 is spaced apart from the spherical crown plate 4 to avoid interfering with the horizontal displacement of the spherical crown plate 4.

[0026] In one specific embodiment of this utility model, such as Figure 1 As shown, the bottom surface of the mounting groove 3 is fixedly connected to the first flat sliding plate 8, and the bottom surface of the spherical crown plate 4 is fixedly connected to the first flat steel plate 9. The first flat steel plate 9 and the first flat sliding plate 8 are slidably connected. This reduces the frictional resistance between the spherical crown plate 4 and the bottom surface of the mounting groove 3, allowing the spherical crown plate 4 to slide more smoothly in the mounting groove 3, ensuring the flexibility of the support during rotation.

[0027] In one specific embodiment of this utility model, such as Figure 1 As shown, a spherical sliding plate 10 is provided on the top surface of the spherical crown plate 4, and the bottom surface of the spherical liner plate 5 is slidably connected to the spherical sliding plate 10. The spherical sliding plate 10 further reduces the friction between the spherical liner plate 5 and the spherical crown plate 4, ensuring that the spherical liner plate 5 can rotate on the spherical crown plate 4 to adapt to loads in different directions.

[0028] In one specific embodiment of this utility model, such as Figure 1 As shown, the top surface of the spherical liner plate 5 is fixedly connected to the second planar sliding plate 11, and the bottom surface of the lower support plate 2 is fixedly connected to the second planar steel plate 12. The second planar steel plate 12 and the second planar sliding plate 11 are slidably connected. This structure ensures smooth sliding between the lower support plate 2 and the spherical liner plate 5, enabling the support to achieve stable displacement and rotation when bearing load.

[0029] It should be noted that the first flat steel plate 9 and the second flat steel plate 12 are both made of stainless steel, while the first flat sliding plate 8, the second flat sliding plate 11 and the spherical sliding plate 10 are all made of polytetrafluoroethylene.

[0030] In one specific embodiment of this utility model, such as Figure 2 As shown, the buffer assembly 7 includes a hydraulic cylinder 701, which is bolted to the bottom surface of the lower support plate 2. The hydraulic cylinder 701 is filled with silicone oil 702, and a sealing cap 703 is threadedly connected to one end near the spherical liner plate 5. A piston head 704 is slidably connected to the inner wall of the hydraulic cylinder 701, with an oil hole 705 extending through it. A piston rod 706 is welded to the piston head 704 and slidably connected to the sealing cap 703. A drive block 707 is welded to the end of the piston rod 706 away from the piston head 704, and a reset element is provided between the drive block 707 and the hydraulic cylinder 701. When the support is subjected to a horizontal load, the drive block 707 moves the piston rod 706 and piston head 704 within the hydraulic cylinder 701. The silicone oil 702 flows through the oil hole 705, generating damping force, consuming the energy of the horizontal load, and thus providing shock absorption.

[0031] Specifically, the reset component includes a compression spring 708, which is sleeved on the outer wall of the piston rod 706 and positioned between the hydraulic cylinder 701 and the drive block 707. When the horizontal load disappears, the compression spring 708 releases its elastic potential energy, pushing the drive block 707 and the piston rod 706 to reset, causing the piston head 704 to return to its initial position, preparing for the next shock absorption.

[0032] Specifically, a guide cylinder 709 is fitted over the compression spring 708. A piston rod 706 passes through one end of the guide cylinder 709 near the hydraulic cylinder 701, and the other end of the guide cylinder 709 is open. The drive block 707 is slidably connected to the inner wall of the guide cylinder 709. One end of the compression spring 708 is fixedly welded to the inner bottom surface of the guide cylinder 709, and the other end is fixedly welded to the drive block 707. The guide cylinder 709 provides guidance for the drive block 707 and the compression spring 708, preventing the compression spring 708 from twisting or deforming during extension and retraction, and ensuring the stable and reliable operation of the buffer assembly 7.

[0033] The working principle of this utility model is as follows: When the damping and shock-absorbing spherical bearing of this utility model is used, under vertical load, the load is transmitted sequentially through the upper support plate 1 and the lower support plate 2 to the spherical liner plate 5. The spherical liner plate 5 compresses the disc spring 6, and the disc spring 6 absorbs energy through compression deformation. At the same time, the sliding fit between the spherical crown plate 4, the spherical liner plate 5, and the bottom surface of the mounting groove 3 allows the bearing to rotate to a certain extent. When encountering horizontal loads such as earthquakes or strong winds, the upper structure drives the lower support plate 2 to produce horizontal displacement. The drive block 707 moves under the action of horizontal force, driving the piston rod 706 and the piston head 704 to slide within the hydraulic cylinder 701. The silicone oil 702 flows through the oil hole 705 to generate damping force, hindering the movement of the piston head 704 and converting the energy of the horizontal load into heat energy for dissipation. When the horizontal load disappears, the compression spring 708 pushes the drive block 707 to reset, allowing the bearing to return to its initial state. Through the coordinated operation of disc spring 6 and buffer assembly 7, the support achieves effective vibration reduction in multiple directions, reducing the risk of structural damage.
