Description

Technical Field

[0001] The utility model relates to the technical field of earthquake resistance in construction engineering, and particularly relates to an installation structure of a viscous damper. Background Technique

[0002] A viscous damper is made based on the principle that viscous resistance is generated when fluid passes through a throttle hole. It is a damper related to stiffness and speed, and is widely used in high-rise buildings, bridges, seismic retrofit of building structures, seismic resistance of industrial pipeline equipment, military industry and other fields.

[0003] In the prior art (publication number: CN210827904U), there is a viscous damper and its installation structure. A viscous damper includes a first installation part at one end of a cylinder body, and the first installation part is used to connect the cylinder body and a support body; a second installation part at one end of a piston rod, and the second installation part is used to connect the piston rod and the support body; wherein, the first installation part and the second installation part respectively include at least one hinge point, and each hinge point enables the coaxial axis of the cylinder body and the piston rod to rotate in at least two planes. In the technical solution of the utility model, when there is a tendency of out-of-plane rotation of the building in the coaxial axis of the cylinder body and the piston rod due to the approach of natural disasters, through the setting of the hinge points, the above rotation can be realized, avoiding the problem of axis misalignment of the cylinder body and the piston rod caused by the rigid connection at the ends of the cylinder body and the piston rod, thereby ensuring the buffering effect of the entire viscous damper, and avoiding losing the protective significance for the building due to the damage of the internal structure before it absorbs and consumes energy.

[0004] In the prior art, the two ends of a viscous damper are usually installed on a building by means of hinges respectively. The two ends of the viscous damper are hinged but other parts are suspended. However, due to the self-weight of the cylinder barrel, the cylinder barrel tilts, so that 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 application of the viscous damper, the wear of the dynamic seal is aggravated, and its service life is far lower than the design expectation. Therefore, an installation structure of a viscous damper is proposed. Content of the Utility Model

[0022] Embodiment 1:

[0023] Please refer to Figures 1-4, the utility model provides a technical solution: a viscous damper installation structure, including two first rotating blocks 2.

The outer surfaces of the two first rotating seats 5 are rotatably connected with second rotating blocks 6. The outer surfaces of the two rotating blocks are fixedly connected with threaded barrels 7. A threaded rod 8 is threadedly connected inside the threaded barrel 7. The other end of the threaded rod 8 is rotatably connected with a third rotating block 9. The outer surface of the third rotating block 9 is rotatably connected with a second rotating seat 10. Adjust the angles of the threaded rod 8 and the threaded barrel 7 so that the threaded rod 8 and the threaded barrel 7 drive the second rotating block 6 and the third rotating block 9 to rotate between the first rotating seat 5 and the second rotating seat 10 respectively. Rotate the threaded rod 8 to adjust the distance between the threaded barrel 7 and the screw rod 13. Then fix one end of the second rotating seat 10. Support the suspended section of the damper body 3 through the threaded barrel 7 and the threaded rod 8, so that the cylinder barrel always remains in a horizontal state. The dynamic seal between the cylinder barrel of the viscous damper and the piston rod inside the cylinder barrel is evenly pressed, reducing the wear of the dynamic seal, making the movement state more stable, and increasing the service life of the viscous damper.

[0024] It also includes two first embedded horizontal plates 11. The opposite outer surfaces of the two first embedded horizontal plates 11 are fixedly connected with fixed side plates 1. The opposite outer surfaces of the two first embedded horizontal plates 11 are provided with movable side plates 12. Threaded holes are opened on the outer surfaces of the two fixed side plates 1. Through holes are opened on the outer surfaces of the two movable side plates 12. Mounting holes are opened on the outer surfaces of the two first rotating blocks 2. A screw rod 13 is threadedly connected inside the threaded hole. The screw rod 13 sequentially passes through the through hole, the mounting hole and the inside of the threaded hole movably. In this embodiment, when installing the damper body 3, place the first rotating block 2 on one side of the fixed side plate 1, and align the mounting hole of the first rotating block 2, the through hole and the threaded hole on the fixed side plate 1. Pass the screw rod 13 through the through hole and the mounting hole in sequence, and screw it into the threaded hole. Control the friction force between the fixed side plate 1 and the movable side plate 12 and the first rotating block 2 by adjusting the depth of the screw rod 13.

[0025] It also includes two second embedded horizontal plates 14. The two second embedded horizontal plates 14 are arranged in a front-back staggered manner. The top outer surfaces of the two second embedded horizontal plates 14 are fixedly connected with mounting plates 15. Ear plates are fixedly connected to the front and rear outer surfaces of the second rotating seat 10. Fixing holes are opened on the outer surfaces of the ear plates and the mounting plates 15. A bolt 16 is threadedly connected inside the fixing hole. In this embodiment, the fixing holes on the ear plates of the second rotating seat 10 correspond to the fixing holes on the mounting plates 15. Fix the second rotating seat 10 on the mounting plate 15 through the bolt 16 and the nut.

[0026] The outer surfaces of the two first embedded horizontal plates 11 facing each other are both provided with sliding grooves 17. Inside both of the two sliding grooves 17, there are fixedly connected sliding rods 18. The outer surfaces of both of the two sliding rods 18 are movably sleeved with sliders. The two movable side plates 12 are respectively fixedly connected to the outer surfaces of the two sliders. In this embodiment, by adjusting the screwing depth of the adjusting screw 13, the screw 13 drives the movable side plate 12 to make the slider slide on the outer surface of the sliding rod 18, increasing the friction between the movable side plate 12, the fixed side plate 1 and the first rotating block 2.

[0027] A plurality of first embedded vertical plates 4 are fixedly connected to the outer surfaces of the two first embedded horizontal plates 11 facing away from each other. In this embodiment, when pouring the building, a plurality of first embedded vertical plates 4 are embedded in appropriate positions in the building, and the first embedded horizontal plates 11 are located on the surface of the building.

[0028] A plurality of second embedded vertical plates are fixedly connected to the bottom outer surfaces of the two second embedded horizontal plates 14. In this embodiment, when pouring the building, a plurality of second embedded vertical plates are embedded in appropriate positions in the building, and the second embedded horizontal plates 14 are located on the surface of the building.

[0029] Both the threaded barrel 7 and the threaded rod 8 are made of stainless steel. In this embodiment, the strength of the threaded barrel 7 and the threaded rod 8 is improved by using stainless steel for the threaded barrel 7 and the threaded rod 8.

[0030] Working principle: When the present utility model is in use, first, according to the size of the damper body 3 and the position of the first rotating seat 5, during the pouring of the building, the first embedded horizontal plates 11 and the second embedded horizontal plates 14 are embedded in appropriate positions. Then, the damper body 3 is installed. The first rotating block 2 is placed on one side of the fixed side plate 1, and the mounting holes, through holes of the first rotating block 2 and the threaded holes on the fixed side plate 1 are made to correspond. The screw 13 passes through the through hole and the mounting hole in sequence and is screwed into the threaded hole. By adjusting the depth of the screw 13, the friction between the fixed side plate 1, the movable side plate 12 and the first rotating block 2 is controlled. Then, by rotating the threaded rod 8, the distance between the threaded barrel 7 and the screw 13 is adjusted, and the position of the second rotating seat 10 is adjusted so that the fixing holes of the ear plates on the second rotating seat 10 correspond to the fixing holes on the mounting plate 15. The second rotating seat 10 is fixed to the mounting plate 15 through the bolt 16 and the nut. Thus, the suspended section of the damper body 3 is supported by the threaded barrel 7 and the threaded rod 8, so that the cylinder barrel always remains in a horizontal state. The dynamic seal between the cylinder barrel of the viscous damper and the piston rod in the cylinder barrel is evenly pressed, reducing the wear of the dynamic seal, making the movement state more stable, and increasing the service life of the viscous damper.
