Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbing equipment, and in particular relates to a building shock absorbing and isolating device. Background Art

[0002] From the mortise and tenon structure of ancient China to the elastic buildings and ball bearing buildings of modern Western countries, human beings have always been exploring ways to deal with earthquakes at the boundaries of engineering technology of the times. When a building reaches a certain height, it will be difficult to simply increase the stiffness of the structural lateral force resistance system. Some super high-rise buildings or bridges will add dampers to reduce the vibration response of the structure, including viscous fluid dampers. Viscous fluid dampers are a type of oil cylinder structure filled with damping medium. The reciprocating motion of the piston drives the flow of the internal medium to produce a damping effect, thereby converting kinetic energy into heat energy.

[0003] The viscous fluid dampers in the prior art are often installed at the bottom of buildings or key structures. These dampers are exposed to different ambient temperatures. Over time, rust, mud and dust will form on their surfaces to varying degrees, which will damage the structure of the damper in the long run. In particular, the guide rods exposed to the outside of the cylinder body will seriously affect the shock absorption performance once rusted and damaged, requiring maintenance personnel to regularly inspect and maintain them. Utility Model Content

[0004] The purpose of the utility model is to provide a building seismic isolation device, which can more conveniently remove the mud and dust adhered to the outside of the cylinder and the rust produced when inspecting and repairing the damper, can disassemble and replace the scraper and can protect the guide rod to prevent the guide rod from being eroded by rain stains, thereby facilitating the cleaning and protection work of the staff and extending the service life of the damper.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A building seismic isolation device comprises a cylinder body, a cover plate and a moving ring, wherein the outer wall of the cylinder body is slidably assembled with the moving ring, the moving ring is arranged in a hollow circular ring shape, the inner ring of the moving ring is fixedly connected with a protrusion, the inner walls on both sides of the moving ring are fixedly connected with sliding blocks, both sides of the cylinder body are provided with sliding grooves for the sliding blocks to slide, one side of the protrusion is movably sleeved with a scraper, both sides of the cylinder body and one end of the sliding groove are fixedly connected with fixed blocks, the fixed blocks are fixedly connected to the sliding blocks via a fixedly connected spring column, and the moving ring is fixedly connected to the cover plate via a fixedly connected hose.

[0007] A guide rod is slidably connected inside the cylinder body, and the cover plate is fixedly mounted on one end of the guide rod.

[0008] One end of the cover plate is fixedly connected with a spherical hinge.

[0009] The spherical joints are arranged in a group, each group consists of two spherical joints, and another spherical joint is fixedly connected to the bottom of the cylinder body.

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] like Figure 1-4As shown, a building seismic isolation device comprises a cylinder body 1, a cover plate 102 and a moving ring 2, wherein a guide rod 105 is slidably connected inside the cylinder body 1, the cover plate 102 is fixedly mounted on one end of the guide rod 105, a spherical hinge 101 is fixedly connected to one end of the cover plate 102, the spherical hinge 101 is arranged as a group, a group of two, another spherical hinge 101 is fixedly connected to the bottom of the cylinder body 1, a moving ring 2 is slidably assembled on the outer wall of the cylinder body 1, the moving ring 2 is arranged in a hollow annular shape, a protrusion 202 is fixedly connected to the inner ring of the moving ring 2, sliding blocks 205 are fixedly connected to the inner walls of the moving ring 2 on both sides, and the cylinder body 1 is opened on both sides. A sliding groove 104 is provided for the sliding block 205 to slide, a scraper 203 is movably sleeved on one side of the protrusion 202, and a groove 206 is provided around the scraper 203 for the protrusion 202 to be embedded. The two ends of the movable ring 2 are detachably connected to the scraper 203 by screws 204, and handles 201 are fixedly connected on both sides of the movable ring 2. Fixed blocks 106 are fixedly connected on both sides of the cylinder body 1 and at one end of the sliding groove 104. The fixed block 106 is fixedly connected to the sliding block 205 through a fixedly connected spring column 107, and the movable ring 2 is fixedly connected to the cover plate 102 through a fixedly connected hose 103.

[0022] According to the above structure, when cleaning the damper, since the movable ring 2 is slidably connected to the sliding groove 104 on the outer wall of the cylinder body 1 through the sliding block 205, the movable ring 2 can be slid toward one end of the cylinder body 1 by pinching the handle 201. During sliding, the scraper 203 sleeved on one side of the protrusion 202 can scrape off the dust and rust condensed on the outer wall of the cylinder body 1. When the scraper 203 slides to one end of the cylinder body 1, since the fixed block 106 and the sliding block 205 are connected through the spring column 107, the spring column 107 will automatically pull the movable ring 2 back to the initial position. During the sliding process of the movable ring 2, due to the characteristics of the hose 103, the hose 103 will move with the movement of the movable ring 2.

After the wiping is completed, the scraper 203 is sleeved with the protrusion 202 through the groove 206, and the screw 204 is screwed on to complete the fixation. The utility model can more conveniently remove the mud and rust adhered to the outside of the cylinder body 1 when inspecting and repairing the damper, the scraper 203 can be disassembled and replaced, and the guide rod 105 can be protected to prevent the guide rod 105 from being eroded by rain stains, which is convenient for the cleaning and protection work of the staff and prolongs the service life of the damper.

[0023] The working principle of the utility model is as follows: when cleaning the damper, since the movable ring 2 is slidably connected to the sliding groove 104 of the outer wall of the cylinder body 1 through the sliding block 205, the movable ring 2 can be slid toward one end of the cylinder body 1 by pinching the handle 201. When sliding, the scraper 203 sleeved on one side of the protrusion 202 can scrape off the dust and rust condensed on the outer wall of the cylinder body 1. When the scraper 203 slides to one end of the cylinder body 1, the fixed block 106 and the sliding block 205 are connected through the spring column 107. When the moving ring 2 is connected, the spring column 107 will automatically pull the moving ring 2 back to the initial position. During the sliding of the moving ring 2, due to the characteristics of the hose 103, the hose 103 will extend as the moving ring 2 slides, and the guide rod 105 is always protected. If there are a lot of stains on the scraper 203, the screw 204 can be unscrewed and the scraper 203 can be taken out for wiping. After wiping, the scraper 203 is connected to the protrusion 202 through the groove 206, and the screw 204 is screwed on to complete the fixation.
