Description

Technical Field

[0001] The present invention relates to the field of vibration and seismic reduction of bridge structures, and particularly to a viscous damping system with an installation structure. Background Art

[0002] With the booming development of the domestic bridge construction industry, bridge construction is also developing towards large spans, and the requirements for the seismic performance of bridges are becoming increasingly strict. Viscous dampers can provide additional damping for bridge structures, dissipate the vibration energy of structures quickly and efficiently, and reduce the seismic response of structures, becoming an important device for bridge structure vibration control.

[0003] In related technologies, when installing a viscous damper on a bridge, generally one end of the viscous damper is installed on the main girder by means of hinge connection, and the other end is installed on the bridge tower or pier by means of hinge connection, and its installation length, that is, the center distance between the pins at both ends of the viscous damper, is usually greater than 5 times the design stroke of the damper, resulting in a large installation space requirement for the viscous damper. Moreover, due to the self-weight of the viscous damper, the dynamic seal between the cylinder barrel of the viscous damper and the piston rod inside the cylinder barrel is in a state of unilateral pressure for a long time. During the actual bridge application process of the viscous damper, the wear of the dynamic seal is aggravated, and its service life is far lower than the design expectation. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a viscous damping system with an installation structure to solve the problems in related technologies that the installation space requirement for the viscous damper is large, and due to the self-weight of the viscous damper, the wear of the dynamic seal inside the viscous damper is aggravated, and its service life is far lower than the design expectation.

[0005] To achieve the above purpose, a viscous damping system with an installation structure is provided, which includes: a viscous damper, the viscous damper includes: a cylinder barrel, a piston is arranged inside the cylinder barrel; a piston rod, one end of which is connected to the piston, and the other end extends out of the cylinder barrel and is provided with an ear plate for connecting to the main girder; a connection component for being hinged to a tower end support below it, which is fixed to one end of the cylinder barrel close to the ear plate; and an installation structure, the installation structure includes an elastic component supported below the viscous damper, the lower part of the elastic component is used to be fixed to the tower end support, and the upper part is connected to the cylinder barrel.

[0006] In some embodiments, the elastic component includes a telescopic frame and a spring arranged inside the telescopic frame, and the telescopic frame is supported in the middle of the cylinder barrel.

[0007] In some embodiments, a fixing block is provided at the bottom of the cylinder barrel, and a protrusion is provided at the top of the telescopic frame. The protrusion is received in the pin shaft hole of the fixing block, so that the telescopic frame can rotate relative to the fixing block.

[0008] In some embodiments, the telescopic frame includes an upper frame and a lower frame. The bottom of the lower frame is assembled on the tower end support, and a slot with an upward opening is provided inside the lower frame; the upper frame is sleeved outside the lower frame and can move up and down relative to the lower frame. An insertion plate inserted into the slot is provided inside the upper frame.

[0009] In some embodiments, the spring includes a first spring and a second spring sleeved outside the first spring, and the first spring and the second spring have opposite winding directions.

[0010] In some embodiments, the viscous damping system with the mounting structure further includes: a guide rail fixed on the tower end support, the guide rail being perpendicular to the cylinder barrel; a slider fixed to the bottom of the elastic component, and the slider can slide on the guide rail.

[0011] In some embodiments, the connection component includes: a support frame fixed to the cylinder barrel by bolts; and a connection frame sleeved outside the support frame. The connection frame is used for being hinged to the tower end support below it, and the support frame is hingedly connected to the connection frame.

[0012] In some embodiments, first grooves are respectively provided on the upper and lower sides of the support frame. First spherical plain bearings are provided in the first grooves. A first pin shaft sequentially passes through the connection frame and the first spherical plain bearings to hinge the support frame and the connection frame together, and the center lines of the upper and lower two first pin shafts are collinear.

[0013] In some embodiments, second grooves are respectively provided on the front and rear sides of the connection frame. Second spherical plain bearings are provided in the second grooves. By sequentially passing a second pin shaft through the tower end support and the second spherical plain bearings, the connection frame and the tower end support can be hinged together, and the center lines of the front and rear two second pin shafts are collinear.

[0014] In some embodiments, the first pin shaft is a stepped pin shaft, and the first pin shaft and the connection frame and the first spherical plain bearings are all in close fit; the second pin shaft is a stepped pin shaft, and the second pin shaft and the tower end support and the second spherical plain bearings are all in close fit.

[0015] The beneficial effects brought by the technical solution provided by the present invention include:

[0016] An embodiment of the present invention provides a viscous damping system with an installation structure. Since the ear plate at one end of the piston rod is connected to the main beam, and one end of the cylinder barrel close to the ear plate is hinged to the tower end support through the connection component, the distance between the hinge point where the viscous damper is installed on the tower end support and the connection point where it is installed on the main beam is approximately 1 time the maximum one-way design stroke of the piston rod. The on-site installation of the viscous damper can be completely carried out on the bridge tower cross beam where the tower end support is placed, without the need to build an extended installation platform, effectively reducing the installation space of the viscous damper. And because the elastic component is arranged below the cylinder barrel, the elastic component can support the cylinder barrel, effectively preventing the weight of the cylinder barrel from being transmitted to the piston rod. The piston rod will not downwardly extrude the dynamic seal between it and the cylinder barrel, greatly improving the unilateral wear condition of the dynamic seal between the piston rod and the cylinder barrel. Therefore, the overall service life of the viscous damper can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The embodiments of the present invention provide a viscous damping system with an installation structure, which can solve the problems in the related art that the installation space requirement of the viscous damper is relatively large, and due to the self-weight of the viscous damper, the dynamic seal in the viscous damper is severely worn, and its service life is far lower than the design expectation.

[0025] See Figure 1 As shown, a viscous damping system with an installation structure provided by an embodiment of the present invention includes: a viscous damper; and an installation structure for installing the viscous damper.

[0026] See Figure 1 As shown, in some embodiments, the viscous damper may include: a cylinder barrel 1, a piston is arranged in the cylinder barrel 1; a piston rod 3, connecting the piston, and an ear plate 4 for connecting the main beam 7 is arranged at one end of the piston rod 3; a connection component 5 hinged to the tower end support 81 below it, and it is fixed at one end of the cylinder barrel 1 close to the ear plate 4.

[0027] See Figure 1As shown, in some embodiments, the main beam 7 may be provided with a beam end support 71 for fixing the viscous damper. The beam end support 71 may include a first fixing plate. The bridge tower 8 located at the bottom of the main beam 7 may also be provided with the tower end support 81 for fixing the viscous damper. The tower end support 81 may include two second fixing plates. Taking the height direction of the main beam 7 as the up-down direction, the longitudinal direction of the main beam 7 as the left-right direction, and the width direction of the main beam 7 as the front-back direction.

[0028] See Figure 1 As shown, in some embodiments, the cylinder 1 may be cylindrical, and damping liquid may be provided on opposite sides of the piston within the cylinder 1. A left end cover 11 for sealing the left end of the cylinder 1 may be provided on the left end face of the cylinder 1, and a right end cover 12 for sealing the right end of the cylinder 1 may be provided on the right end face of the cylinder 1. Both the left end cover 11 and the right end cover 12 may be fixed to the cylinder 1 by bolts. A fixing block 13 may be provided at the bottom of the cylinder 1, and the fixing block 13 may be fixed to the middle of the cylinder 1. A pin shaft hole may be recessed upward from the bottom surface of the fixing block 13.

[0029] See Figure 1 and Figure 2As shown, in some alternative embodiments, the middle part of the piston rod 3 may be connected to the piston. The piston rod 3 can drive the piston to slide within the cylinder barrel 1, generating a damping force simultaneously to achieve the normal vibration reduction and energy dissipation function of the viscous damper. The left end of the piston rod 3 extends out of the cylinder barrel 1. The ear plate 4 can be threadedly connected to the left end of the piston rod 3, and the ear plate 4 can be hinged to the beam end support 71. Specifically, the ear plate 4 can be in the form of a double ear, and a through groove 41 running through from front to back is provided between the double ears. The first fixing plate can be received within the through groove 41, and the first fixing plate is provided with a through hole running through from top to bottom. A third spherical plain bearing 42 can be provided within the through hole. The ear plate 4 can be hinged to the beam end support 71 by passing a third pin shaft 43 through the ear plate 4 and the third spherical plain bearing 42. A positioning ring 44 can be sleeved outside the third pin shaft 43, and the positioning ring 44 is provided on the upper and lower sides of the third spherical plain bearing 42. The transverse hinging mode of the ear plate 4 can meet the greater angular displacement requirements when relative transverse displacement occurs between the bridge tower 8 and the main beam 7. The piston rod 3 can extend rightward through the right end cover 12, and a dust cover 9 can be provided on the right side of the right end cover 12. The piston rod 3 can be received within the dust cover 9 to protect the piston rod 3 from external contamination and damage such as dust. Dynamic seals are provided between the piston rod 3 and the left end cover 11, and between the piston rod 3 and the right end cover 12. The dynamic seals are used to prevent the damping fluid within the cylinder barrel 1 from leaking out through the gaps between the piston rod 3 and the left end cover 11, and between the piston rod 3 and the right end cover 12.

[0030] See Figure 1 and Figure 3 As shown, in some embodiments, the connection assembly 5 may include a support frame 51. The support frame 51 can be provided on the left side of the left end cover 11 and be in close contact with the left end cover 11. The support frame 51 and the left end cover 11 can be fixed to the left end of the cylinder barrel 1 by the same set of bolts. First grooves 511 can be respectively provided on the upper and lower sides of the support frame 51. The upper first groove 511 can be recessed downward from the upper surface of the support frame 51, and the lower first groove 511 can be recessed upward from the lower surface of the support frame 51. First spherical plain bearings 512 can be provided within both of the two first grooves 511. A central hole for the piston rod 3 to pass through can be provided at the center of the support frame 51. A dust cover 9 can also be provided between the support frame 51 and the ear plate 4, and the piston rod 3 can be received within the dust cover 9.

[0031] See Figure 1 and Figure 3As shown, in some alternative embodiments, the connection assembly 5 may further include a connection frame 52 sleeved outside the support frame 51. First pin 513 holes may be respectively provided on the upper and lower sides of the connection frame 52. By sequentially passing a first pin 513 through the first pin 513 holes and the first spherical plain bearing 512, the support frame 51 and the connection frame 52 can be hinged together. Moreover, the first pin 513 is a stepped pin, and the first pin 513 is in a tight fit with both the first pin 513 hole and the first spherical plain bearing 512. The symmetry centerlines of the upper first pin 513 and the lower first pin 513 are located on the same vertical line, and on the same cross-section, the symmetry centerline of the first pin 513 and the radial centerline of the piston rod 3 are located on the same straight line. By connecting the support frame 51 and the connection frame 52 through two upper and lower first spherical plain bearings 512, the support frame 51 can drive the cylinder barrel 1 to rotate forward and backward by a certain angle around the symmetry centerline of the first pin 513, making the lateral rotation of the cylinder barrel 1 more flexible. When a lateral relative displacement occurs between the tower end support 81 and the beam end support 71, the first spherical plain bearing 512 plays a role and drives the cylinder barrel 1 to adapt to the lateral deflection angle. At the same time, it can avoid the phenomenon that the cylinder barrel 1 gets stuck in rotation caused by the non-concentricity of the two first pin 513 holes on the same centerline due to manufacturing errors. Moreover, a first cover plate 514 for fixing the first pin 513 is provided on the outer end surface of the first pin 513.

[0032] See Figure 1 and Figure 3As shown, in some embodiments, second grooves 521 may be respectively provided on the front and rear sides of the connection frame 52. Second spherical plain bearings 522 may be provided in the second grooves 521. The second fixing plate may be provided with holes for second pin shafts 523 corresponding to the second grooves 521. By sequentially passing the second pin shafts 523 through the holes for the second pin shafts 523 and the second spherical plain bearings 522, the second fixing plate and the connection frame 52 can be hinged together. Moreover, the second pin shafts 523 are stepped pin shafts, and the second pin shafts 523 are in close fit with both the holes for the second pin shafts 523 and the second spherical plain bearings 522. The symmetry center lines of the front second pin shafts 523 and the rear second pin shafts 523 are located on the same vertical line. And on the same cross-section, the symmetry center line of the first pin shaft 513 and the radial center line of the piston rod 3 are located on the same straight line. By connecting the second fixing plate and the connection frame 52 through the front and rear two second spherical plain bearings 522, the connection frame 52 can drive the support frame 51 to rotate up and down by a certain angle around the symmetry center line of the second pin shaft 523, making the vertical rotation of the cylinder barrel 1 more flexible. When a vertical relative displacement occurs between the tower end support 81 and the beam end support 71, the second spherical plain bearings 522 play a role and drive the cylinder barrel 1 to adapt to the vertical deflection angle. At the same time, it is possible to avoid the phenomenon that the cylinder barrel 1 rotates and jams caused by the non-concentricity of the two holes for the second pin shafts 523 on the same center line due to manufacturing errors. And a second cover plate 524 for fixing the second pin shaft 523 is provided on the outer end surface of the second pin shaft 523. The first spherical plain bearing 512 may be of the same type as the second spherical plain bearing 522, both being radial spherical plain bearings. Since the connection assembly 5 is provided at one end of the cylinder barrel 1 close to the ear plate 4, and the connection frame 52 is hinged to the tower end support 81, the distance between the hinge point where the viscous damper is installed on the tower end support 81 and the hinge point at the ear plate 4 is approximately 1 time the maximum one-way design stroke of the piston rod 3. The on-site installation of the viscous damper can be completely carried out on the cross beam of the bridge tower 8 where the tower end support 81 is placed, without the need to build an extended installation platform, effectively reducing the installation space of the viscous damper.

[0033] See Figure 1 and Figure 4As shown, in some alternative embodiments, the mounting structure may include an elastic component 2 supported below the viscous damper. The elastic component 2 may include a telescopic frame 21 and a spring 22 disposed within the telescopic frame 21. The telescopic frame 21 may include a lower frame 212 which may be mounted on the tower end support 81, and the lower frame 212 may be a square frame body with an upward opening. A slot 2121 with an upward opening may be provided within the lower frame 212, and an outwardly horizontally extending lower extension plate 2122 may be formed on the outer wall surface of the lower frame 212. The telescopic frame 21 may further include an upper frame 211 sleeved outside the lower frame 212. The upper frame 211 may be a square frame body with a downward opening. A downwardly extending insertion plate 2111 may be provided within the upper frame 211, and the insertion plate 2111 may be inserted into the slot 2121. The upper frame 211 may move up and down relative to the lower frame 212, and the insertion plate 2111 may function as a guide. A protrusion 2113 may be provided at the top of the upper frame 211. Preferably, the protrusion 2113 is provided at the center of the top surface of the upper frame 211. The protrusion 2113 may be received in the pin hole of the fixed block 13. When the fixed block 13 rotates back and forth around the symmetry center line of the first pin 513 together with the cylinder barrel 1, the fixed block 13 may rotate relative to the upper frame 211. The protrusion 2113 may enable the upper frame 211 to adapt to the rotation of the fixed block 13. Also, an outwardly horizontally extending upper extension plate 2112 may be formed on the outer wall surface of the upper frame 211. During the process of installing the protrusion 2113 onto the fixed block 13, a jack may be used to compress the upper frame 211 downward to the installation length, and then the upper extension plate 2112 and the lower extension plate 2122 may be temporarily fixed with bolts. Then, the jack may be released, and the protrusion 2113 may be installed into the pin hole of the fixed block 13. Then, the bolts on the upper extension plate 2112 may be removed to complete the installation of the elastic component 2. And the elastic component 2 may balance the self-weight of the cylinder barrel 1 part. Since the elastic component 2 is mounted on the tower end support 81 and the tower end support 81 is fixed to the bridge tower 8, when the main beam 7 and the bridge tower 8 have a longitudinal relative displacement, the elastic component 2 will not be longitudinally pulled and will not be affected.

[0034] See Figure 1 and Figure 4As shown, in some embodiments, the spring 22 is preferably a cylindrical helical compression spring 22, and the spring 22 may include a first spring 22 and a second spring 22 sleeved outside the first spring 22. The first spring 22 and the second spring 22 may have opposite winding directions. Using a double-layer spring 22 can ensure more stability during the compression process of the elastic component 2.

[0035] See Figure 1 and Figure 4 As shown, in some alternative embodiments, the viscous damping system with an installation structure may further include a guide rail 6. The guide rail 6 can be fixed to the tower end support 81 by bolts, and the guide rail 6 can be arranged perpendicular to the cylinder barrel 1 (i.e., horizontally arranged), and a slider 61 fixed to the bottom surface of the lower frame 212 by bolts. The slider 61 can slide on the guide rail 6 and can drive the elastic component 2 to move back and forth on the guide rail 6 together, so that the elastic component 2 can drive the viscous damper to achieve lateral movement; when a lateral displacement (i.e., the front-back direction) occurs between the bridge tower 8 and the main beam 7, the cylinder barrel 1 drives the elastic component 2 to slide on the guide rail 6 pair, and the elastic component 2 can still balance the self-weight of the cylinder barrel 1 part. The insertion plate 2111 ensures that the lower frame 212 and the upper frame 211 move together during the sliding process, playing a role in stabilizing the structure.

[0036] The principle of a viscous damping system with an installation structure provided by an embodiment of the present invention is as follows:

[0037] Since the ear plate 4 at one end of the piston rod 3 is connected to the main beam 7, and one end of the cylinder barrel 1 close to the ear plate 4 is hinged to the tower end support 81 through the connection assembly 5, the distance between the hinge point where the viscous damper is installed on the tower end support 81 and the connection point where it is installed on the main beam 7 is about 1 time the maximum one-way design stroke of the piston rod 3. The on-site installation of the viscous damper can be completely carried out on the cross beam of the bridge tower 8 where the tower end support 81 is placed, without the need to build an extended installation platform, effectively reducing the installation space of the viscous damper; and because the elastic component 2 is arranged below the cylinder barrel 1, the elastic component 2 can support the cylinder barrel 1, effectively preventing the weight of the cylinder barrel 1 from being transmitted to the piston rod 3, and the piston rod 3 will not squeeze the dynamic seal between it and the cylinder barrel 1 downward, greatly improving the unilateral wear condition of the dynamic seal between the piston rod 3 and the cylinder barrel 1. Therefore, the overall service life of the viscous damper can be improved.
