Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of earthquake-resistant supports, in particular to a buffer device for an earthquake-resistant support of a building. Background Art
[0002] Building seismic supports are an important seismic measure to protect electromechanical equipment and pipelines. When an earthquake occurs, the buffer device on the seismic support can give full play to its elastic deformation capacity, reduce the impact of the seismic force on the building foundation, and disperse the seismic energy, thereby making the structure of the building more stable and protecting the building and its ancillary facilities from damage.
[0003] When in use, the seismic bracket mainly relies on the elastic deformation ability of the spring inside its buffer device to reduce the impact of earthquake force on the building foundation. However, after a period of use, the elastic performance of the spring gradually decreases, thereby reducing the seismic effect of the seismic bracket.
[0004] Furthermore, when the spring inside the existing buffer device becomes rusty and corroded, it is inconvenient to replace the spring, so the entire buffer device needs to be replaced, which increases the cost of use. Utility Model Content
[0005] The purpose of the utility model is to provide a buffer device for a building earthquake-resistant support, which effectively solves the problems raised in the above-mentioned background technology.
[0006] In order to achieve the above-mentioned purpose, the present utility model provides the following technical solutions.
[0007] A buffer device for a building seismic support comprises a housing with an open top, two hangers inserted within the housing, a slider being provided at the tops of the two hangers, a connecting block being provided at the bottoms of the two hangers, and a lifting block being slidably mounted on the outer surfaces of the two hangers, the lifting blocks being disposed within the housing. Springs are sleeved on the outer surfaces of the hangers, the ends of the springs respectively abutting the slider and the lifting blocks. A rotating shaft is rotatably mounted within the housing, the outer surface of the rotating shaft being provided with external threads, the rotating shaft passing through the interiors of the lifting blocks and the slider, and being threadedly connected to the lifting blocks.
[0008] It can be seen that by twisting the rotating shaft, since the two suspension rods limit the lifting block, and the rotating shaft and the lifting block are threadedly connected, the lifting block can be driven to rise vertically and compress the spring when the rotating shaft is twisted. By compressing the spring, its elastic performance is improved, thereby ensuring the seismic effect of the seismic bracket. The rotating shaft can also limit the slider, thereby improving the stability of the connecting block when it moves up and down.
[0009] Furthermore, a top cover is mounted on the top of the housing by screws, and the upper end of the rotating shaft passes through the outer side of the top cover.
[0010] Furthermore, a hexagonal groove is provided on the top of the rotating shaft.
[0011] Furthermore, side grooves are provided on both sides of the shell, and protrusions are installed on the outer surfaces of both sides of the slider, which extend through the side grooves to the outside of the shell. Two connecting holes are provided on the lower surface of the slider, and the tops of the two suspension rods are respectively inserted into the two connecting holes. Screw holes are provided on the outer surfaces of the suspension rods, and bolts are installed inside the protrusions, and the bolts are adapted to the screw holes.
[0012] Furthermore, hydraulic damping rods are installed on the outer surfaces of both sides of the shell, and the ends of the hydraulic damping rods are connected to the connecting blocks.
[0013] Furthermore, four L-shaped fixing frames are installed on one side of the outer surface of the housing close to the top cover, and the four L-shaped fixing frames are distributed in a coaxial array.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows.
[0015] 1. The utility model can drive the lifting block to rise vertically and compress the spring by twisting the rotating shaft. The two suspension rods limit the lifting block, and the rotating shaft and the lifting block are threadedly connected. The elastic performance of the spring is improved by compressing the spring, thereby ensuring the seismic effect of the seismic bracket. The rotating shaft can also limit the slider, thereby improving the stability of the connecting block when it moves up and down.
[0016] 2. The utility model opens the top cover and then unscrews the bolt from the screw hole, so that the slider can be taken out of the housing, and then the spring is taken out and replaced. Thereafter, the slider is installed into the housing and the bolt is screwed into the screw hole to fix the slider and the suspension rod together. The top cover is then reinstalled by screws, thereby realizing the replacement of the spring without replacing the entire buffer device, thereby reducing the use cost.

[0026] See also Figure 1-Figure 5The present invention provides a buffer device for a building earthquake-resistant support, comprising a housing 100 with an open top structure. Two suspension rods 101 are inserted into the housing 100. A slider 102 is provided on the top of the two suspension rods 101. A connecting block 103 is installed on the bottom of the two suspension rods 101. A lifting block 104 is slidably installed on the outer surface of the two suspension rods 101. The lifting block 104 is disposed inside the housing 100. A spring 105 is sleeved on the outer surface of the suspension rod 101. The two ends of the spring 105 abut against the slider 102 and the lifting block 104, respectively. A rotating shaft 106 is rotatably installed inside the housing 100. The outer surface of the rotating shaft 106 is provided with an external thread 107. The rotating shaft 106 passes through the interior of the lifting block 104 and the slider 102, respectively, and is threadedly connected to the lifting block 104.
[0027] When in use, the connecting block 103 is connected to the bracket. When vibration occurs, the connecting block 103 drives the bracket to move up and down, causing the slider 102 to slide up and down on the outer surface of the suspension rod 101 and compress the spring 105. The deformation of the spring 105 can play a buffering role. When the elastic performance of the spring 105 is reduced, the rotating shaft 106 can be screwed. Since the two suspension rods 101 limit the lifting block 104, and the rotating shaft 106 is threadedly connected to the lifting block 104, the lifting block 104 can be driven to rise vertically and compress the spring 105 when the rotating shaft 106 is screwed. By compressing the spring 105, its elastic performance is improved, thereby ensuring the seismic effect of the seismic bracket, and the rotating shaft 106 can also limit the slider 102, thereby improving the stability of the connecting block 103 when it moves up and down.
[0028] Specifically, a top cover 200 is installed on the top of the shell 100 by screws, and the upper end of the rotating shaft 106 passes through the outside of the top cover 200. Through the setting of the top cover 200, the top of the shell 100 can be sealed, reducing dust from falling into the shell 100 and adhering to the outer surface of the spring 105, thereby reducing the corrosion of the spring 105. Moreover, since the upper end of the rotating shaft 106 passes through the outside of the top cover 200, the spring 105 can be adjusted by twisting the rotating shaft 106 without opening the top cover 200.
[0029] Specifically, a hexagonal slot 300 is provided on the top of the rotating shaft 106 . Through the provision of the hexagonal slot 300 , a hexagonal wrench can be used to drive the rotating shaft 106 to rotate.
[0030] Specifically, side grooves 400 are provided on both sides of the housing 100, and protrusions 401 are installed on the outer surfaces of both sides of the slider 102. The protrusions 401 extend through the side grooves 400 to the outside of the housing 100. The lower surface of the slider 102 is provided with two connecting holes 402, and the tops of the two suspension rods 101 are respectively inserted into the two connecting holes 402. The outer surface of the suspension rod 101 is provided with screw holes 403, and bolts 404 are installed inside the protrusions 401. The bolts 404 are adapted to the screw holes 403. When the performance of the spring 105 cannot meet the use requirements, the top cover 200 can be opened first, and then the bolts 404 can be screwed out from the screw holes 403. At this time, the slider 1 02 is released from the fixation between the suspension rod 101, so the upward sliding protrusion 401 can drive the slider 102 to be taken out from the shell 100, and then the spring 105 is taken out and replaced, and then the slider 102 is installed into the shell 100. Since the side groove 400 and the protrusion 401 limit the slider 102, it is possible to ensure that the top of the suspension rod 101 is accurately inserted into the connecting hole 402, and then the bolt 404 is screwed into the screw hole 403 to fix the slider 102 and the suspension rod 101 together, and then the top cover 200 is reinstalled with screws, thereby realizing the replacement of the spring 105, without replacing the entire buffer device, reducing the cost of use.
[0031] Specifically, hydraulic damping rods 500 are installed on the outer surfaces of both sides of the shell 100, and the ends of the hydraulic damping rods 500 are connected to the connecting blocks 103. Since the spring 105 will freely expand and contract after being impacted or vibrated, this expansion and contraction will last for a period of time, resulting in a longer duration of vibration, which affects the stability of the bracket. Therefore, through the setting of the hydraulic damping rods 500, a damping effect can be provided when the spring 105 expands and contracts, reducing the vibration amplitude and frequency, so that the bracket can be stabilized quickly.
[0032] Specifically, four L-shaped fixing brackets 600 are installed on one side of the outer surface of the shell 100 close to the top cover 200. The four L-shaped fixing brackets 600 are distributed in a coaxial array. Through the setting of the L-shaped fixing bracket 600, it can be connected to the ceiling, and the connecting block 103 is connected to the bracket to realize the lifting of electromechanical equipment and pipelines.
[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
