Description

Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to a protective viscous damper. Background Art

[0002] Traditional structural earthquake resistance is to resist earthquakes, wind, snow, tsunamis and other disasters by enhancing the strength, stiffness and ductility of the structure itself. The structures designed by the traditional earthquake resistance method usually do not have the ability to self-regulate. Therefore, when natural disasters occur, they often cause significant economic losses and casualties. Therefore, viscous dampers are widely used in building earthquake resistance. Viscous energy dissipation dampers are usually installed between two sets of walls. The two connecting ends of the viscous energy dissipation damper are connected to the two sets of walls respectively, so as to achieve the maximum energy dissipation protection effect. When vibration occurs, the viscous damper can absorb and consume the impact energy to the maximum extent.

[0003] At present, when installing a damper with upper and lower staggered connection ends, a connection method in which the lower end is fixed first and then the upper end is fixed is generally adopted. Under this installation method, the upper end of the connector needs to be lifted before it can be connected to the top wall. After the upper end is lifted, bricks are added to keep the upper end in a lifted state. The brick support method has the problem of easy slippage during use, which is high in risk. In view of the above defects, the present utility model is proposed. Utility Model Content

[0004] The utility model aims to provide a protective viscous damper to solve the problem.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a protective viscous damper, comprising a viscous damper body, the two ends of the viscous damper body are respectively connected with a first connecting seat and a second connecting seat through a rotating shaft, the two ends of the rotating shaft for connecting the second connecting seat are both installed with guide seats, a protective support rod is sleeved between the two groups of the guide seats, a limiting rod matching the protective support rod is connected to the surface of the second connecting seat, and a protective support rod follower supplementary member for assisting the protective support rod to be sent out is arranged at the end of the protective support rod;

[0006] The protective support rod slides along the surface of the guide seat to adjust its relative position with the limiting rod, and the protective support rod rotates and engages in the limiting rod. The engaged protective support rod restricts the reverse movement of the limiting rod.

[0007] Preferably, the first connecting seat and the second connecting seat have the same specifications, and the ends of the first connecting seat and the second connecting seat are arranged in opposite directions.

[0008] Preferably, the protective support rod member includes a support rod, a linkage rod, a limit clamp and an anti-slip sleeve. The support rod is provided in two groups, and the two groups of support rods are respectively sleeved in two groups of guide seats. The linkage rod is installed between the ends of the two groups of support rods, and the limit clamp is opened on the surface of the two groups of support rods.

[0009] Preferably, the protective support rod also includes an anti-slip sleeve, which is sleeved on the surface of the linkage rod, and the surface of the anti-slip sleeve is ground.

[0010] Preferably, the position limiting holder is composed of a plurality of groups of semicircular notches arranged at equal intervals, and a side of each group of notches facing away from the linkage rod is rounded.

[0011] Preferably, the limiting rod comprises a threaded hole and a limiting rod, the threaded hole is opened at one side of the end of the second connecting seat, the limiting rod is threadedly connected in the threaded hole, and the limiting rod can move laterally along the inside of the threaded hole.

[0012] Preferably, the diameter of the threaded hole is consistent with the diameter of the semicircular notch, and the end of the limiting rod is hemispherical to match the limiting socket.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is provided with a protective support rod. After the end of the viscous damper body is lifted, the setting position of the support rod relative to the guide seat is changed synchronously. The limit seat on the support rod can slide smoothly after rounded corners, and the engagement connection position with the limit rod can be changed, so as to provide real-time support and supplement, replacing the traditional brick support method to provide stable support for the viscous damper body and prevent the viscous damper body from lateral slipping.

[0016] 2. In the utility model, a protective support rod follow-up supplement is provided. When the end of the viscous damper body is lifted upward, the combination of the support rod and the linkage rod is no longer subjected to force. At this time, the return spring pulls the support rod to move inside the guide seat through the connecting nut, thereby realizing automatic extension and supplement of the support rod.

[0023] The above and other technical features and advantages of the utility model are further described below in conjunction with the accompanying drawings and embodiments. However, the following embodiments are only preferred embodiments of the utility model, not all of them. Example

[0024] like Figure 1-4 As shown, the utility model provides a protective viscous damper, comprising a viscous damper body 1, two ends of the viscous damper body 1 are respectively connected with a first connecting seat 2 and a second connecting seat 3 through a rotating shaft, the first connecting seat 2 and the second connecting seat 3 have the same specifications, the ends of the first connecting seat 2 and the second connecting seat 3 are arranged in opposite directions, the first connecting seat 2 and the second connecting seat 3 are respectively used to connect two groups of disconnected walls, the position change between the first connecting seat 2 and the second connecting seat 3 is absorbed by the deformation of the viscous damper body 1, both ends of the rotating shaft for connecting the second connecting seat 3 are installed with guide seats 4, a protective support rod 5 is sleeved between the two groups of guide seats 4, the surface of the second connecting seat 3 is connected with a limiting rod 6 matching the protective support rod 5, and the end of the protective support rod 5 is provided with a protective support rod follower supplement 7 for assisting the protective support rod 5 to be sent out;

[0025] The protective support rod 5 slides along the surface of the guide seat 4 to adjust its relative position with the limiting rod 6 , and the protective support rod 5 rotates and engages in the limiting rod 6 . The engaged protective support rod 5 limits the reverse movement of the limiting rod 6 .

[0026] The protective support rod 5 includes a support rod 51, a linkage rod 52, a limit clamping seat 53 and an anti-slip sleeve 54;

[0027] There are two groups of support rods 51, and the two groups of support rods 51 are respectively sleeved in the two groups of guide seats 4. The linkage rod 52 is installed between the ends of the two groups of support rods 51. Under the connection of the linkage rod 52, the linkage rod 52 cooperates with the two groups of support rods 51 to form a U-shaped structure that can move synchronously. The two groups of support rods 51 can move synchronously inside the guide seat 4. The linkage rod 52 is supported by the support rods 51 and contacts the wall, and cooperates with the rotating shaft to support the end of the viscous damper body 1. The limit clamping seat 53 is opened on the surface of the two groups of support rods 51, and the limit clamping seat 53 is engaged with the limit rod 6. After engagement, the relative position of the limit clamping seat 53 and the limit rod 6 is fixed.

[0028] The limiting seat 53 is composed of multiple groups of semicircular grooves arranged at equal intervals. When the end of the linkage rod 52 contacts the wall, the setting position of the support rod 51 relative to the limiting rod 6 is fixed. At this time, the limiting rod 6 can be nested in the corresponding semicircular groove. With the cooperation of the second connecting seat 3 and the limiting rod 6, the setting position of the second connecting seat 3 relative to the end of the viscous damper body 1 is fixed. At this time, the second connecting seat 3 can maintain a vertical state for subsequent connection with the wall. The side of each group of grooves away from the linkage rod 52 is rounded. After the end of the viscous damper body 1 is lifted, the setting position of the support rod 51 relative to the guide seat 4 is changed synchronously. After the rounded treatment, the limiting seat 53 on the support rod 51 can slide smoothly to change the engaging connection position with the limiting rod 6, thereby performing real-time support supplement.

[0029] The protective support rod 5 also includes an anti-slip sleeve 54, which is sleeved on the surface of the linkage rod 52, and the surface of the anti-slip sleeve 54 is polished. The anti-slip sleeve 54 can increase the friction with the wall, so that the support rod 51 can stably support the end of the viscous damper body 1.

[0030] The limiting rod 6 includes a threaded hole 61 and a limiting rod 62. The threaded hole 61 is opened on one side of the end of the second connecting seat 3. The limiting rod 62 is threadedly connected to the threaded hole 61. The limiting rod 62 can move laterally along the inside of the threaded hole 61. The diameter of the threaded hole 61 is consistent with the diameter of the semicircular groove. The end of the limiting rod 62 is hemispherical to match the limiting socket 53. In the setting preparation stage, the limiting rod 62 can be received into the threaded hole 61 by rotating the limiting rod 62. The hemispherical shape of the end of the limiting rod 62 can smoothly guide the limiting rod 62 to enter the limiting socket 53 during the process of moving the threaded hole 61 out again, thereby completing the relative nested connection.

[0031] When the cam 72 is in the unlocking state, the locking nut 77 is in the unlocking state, and the locking nut 77 is in the unlocking state, so that the locking nut 77 is locked and the locking nut 77 is locked.

[0032] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
