Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection pipeline support technology, and in particular to a fire protection pipeline support anti-seismic buffer device. Background Technology
[0002] Fire protection pipe supports are structural devices used to support, fix, and secure fire protection pipes. Fire protection pipes typically include fire water pipes, sprinkler system pipes, etc. These pipes need to be fixed to the walls or ground of the building using supports to ensure the stability and normal operation of the pipe system. When using fire protection pipe supports, in order to cope with sudden external vibrations such as earthquakes, seismic buffer devices need to be installed to mitigate the impact of vibrations on the pipes and reduce damage.
[0003] Chinese patent discloses a pipeline seismic support with good buffering effect (publication number CN216078812U). This patented technology uses two buffer blocks placed above two jackets to buffer the severe impact or compression on the top, preventing damage to the jackets. At the same time, the jackets can clamp and fix one end of the pipeline to prevent the pipeline from shaking or shifting after installation. The buffer spring and damping shock absorber at the bottom of the support can support and buffer the vibration pressure on the top of the support, effectively improving the load-bearing capacity and seismic performance of the pipeline.
[0004] However, most existing pipe support systems only provide external shock absorption, failing to protect the pipe itself from vibration. This results in rigid contact between the pipe and the jacket during vibrations, easily causing damage. For example, the aforementioned prior art places the pipe inside the jacket. In practical applications, external vibrations cause rigid wear between the pipe and the jacket, leading to pipe damage and reduced service life. Therefore, those skilled in the art provide a shock-absorbing device for fire-fighting pipe supports to address the problems mentioned in the background. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a seismic buffer device for fire-fighting pipeline supports, which solves the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a seismic buffer device for fire-fighting pipeline supports, comprising: a support base, two first support plates disposed on the upper surface of the support base, a first sleeve installed between the two first support plates, and a second sleeve disposed above the first sleeve. The second support plate is mounted on the upper surface of the first support plate, and a threaded rod is provided through the upper surface of the second support plate. A fixing groove is provided on the inner side of both the first and second sleeves, and a first spring is disposed inside the fixing groove. A buffer plate is also provided on the inner side of the first and second sleeves. Buffer rods are symmetrically arranged on the outer side of the buffer plate inside the fixing groove. A base plate is disposed below the support base, and fixing rods are symmetrically arranged on the upper surface of the base plate. A lifting rod is slidably disposed on the upper end of the fixing rod, and a second spring is sleeved on the outside of the fixing rod and the lifting rod.
[0007] As a further technical solution of this utility model, a bearing is installed at the middle position of the upper surface of the second jacket, the threaded rod is threadedly connected to the second support plate, and the lower end of the threaded rod is embedded in the bearing and rotatably connected to the bearing.
[0008] As a further technical solution of this utility model, two buffer plates are symmetrically arranged on the inner sides of the first and second jackets, and rubber pads are provided on the inner sides of the buffer plates.
[0009] As a further technical solution of this utility model, one end of the first spring is fixed to the inner end of the fixing groove, and the other end of the first spring is fixed to one end of the buffer rod.
[0010] As a further technical solution of this utility model, a limiting plate is also provided on the lower surface of the support base on the outside of the lifting rod, the upper end of the second spring is fixed on the lower surface of the limiting plate, and the lower end of the second spring is fixed on the upper surface of the base plate.
[0011] As a further technical solution of this utility model, a nut is threadedly connected to the outside of the lifting rod above the support base, and the lower surface of the nut contacts the upper surface of the support base.
[0012] This utility model provides a seismic buffer device for fire-fighting pipeline supports, which has the following advantages compared with the prior art:
[0013] 1. This design provides a shock-absorbing buffer device for fire-fighting pipe supports. By setting up a buffer plate, a buffer rod, a fixing groove, and a first spring, when the fire-fighting pipe support is subjected to vibration from external factors, the first spring will play a certain role in buffering deformation, thereby achieving the purpose of shock-absorbing the fire-fighting pipes in the first and second jackets, improving their service life. The structure is simple and practical.
[0014] 2. This design provides a shock-absorbing device for fire-fighting pipeline supports. Through the arrangement of a base plate, a lifting rod, a second spring, a limiting plate, a nut, and a fixing rod, the lifting rod can be connected to the support base using the nut. When the fire-fighting pipeline support vibrates, the lifting rod will rise and fall inside the fixing rod, while the external second spring deforms to achieve the purpose of shock absorption and improve the service life of the fire-fighting pipeline.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a seismic buffer device for fire-fighting pipe supports, comprising: a support base 1, two first support plates 21 disposed on the upper surface of the support base 1, a first clamping sleeve 2 installed between the two first support plates 21, and a second clamping sleeve 3 disposed above the first clamping sleeve 2. The second support plate 31 is mounted on the upper surface of the first support plate 21, and a threaded rod 32 is provided through the upper surface of the second support plate 31. Fixing grooves 42 are provided on the inner sides of both the first clamping sleeve 2 and the second clamping sleeve 3, and a first spring 43 is disposed inside the fixing grooves 42. Buffer plates 4 are also provided on the inner sides of the first clamping sleeve 2 and the second clamping sleeve 3, and the outer side of the buffer plates 4 is located within the fixing grooves 42. The support base 1 is provided with a base plate 5 below the symmetrically arranged buffer rods 41. The upper surface of the base plate 5 is provided with fixed rods 55 symmetrically arranged. The upper end of the fixed rods 55 is slidably provided with lifting rods 51. The fixed rods 55 and lifting rods 51 are sleeved with a second spring 52. This arrangement, by setting a buffer plate 4 inside the first jacket 2 and the second jacket 3, can buffer and protect the internal pipes, avoiding damage to the pipes caused by external vibrations. At the same time, the second spring 52 outside the fixed rods 55 and lifting rods 51 can achieve the purpose of shock absorption and buffering for the fire pipe support formed by the first jacket 2 and the second jacket 3, which is practical.
[0027] like Figure 3 As shown, a bearing is installed at the middle position of the upper surface of the second jacket 3. The threaded rod 32 is threadedly connected to the second support plate 31, and the lower end of the threaded rod 32 is embedded in the bearing and rotatably connected to the bearing. This setting utilizes the rotation of the threaded rod 32 to make it move downward. This is existing technology and will not be discussed here. In this way, when the threaded rod 32 rotates, the second jacket 3 will move downward to clamp and position the pipeline, thus ensuring its stability.
[0028] like Figure 5As shown, two buffer plates 4 are symmetrically arranged inside the first jacket 2 and the second jacket 3, and rubber pads are provided inside the buffer plates 4. One end of the first spring 43 is fixed to the inner end of the fixing groove 42, and the other end of the first spring 43 is fixed to one end of the buffer rod 41. This arrangement allows the first spring 43 to deform when subjected to external vibration, causing the buffer plate 4 to move towards the position of the first jacket 2 and the second jacket 3, thus achieving the purpose of shock absorption for the fire pipeline.
[0029] like Figure 4 As shown, a limiting plate 53 is also provided on the lower surface of the support base 1 on the outside of the lifting rod 51. The upper end of the second spring 52 is fixed to the lower surface of the limiting plate 53, and the lower end of the second spring 52 is fixed to the upper surface of the base plate 5. A nut 54 is also threadedly connected to the outside of the lifting rod 51 above the support base 1. The lower surface of the nut 54 contacts the upper surface of the support base 1. This setting can limit the support base 1 using the limiting plate 53, and limit the lifting rod 51 using the nut 54. In this way, the lifting rod 51 can be installed. The second spring 52 can deform when the device vibrates, thereby achieving the purpose of shock absorption and good practicality.
[0030] The working principle of this utility model is as follows: When using the fire-fighting pipe support anti-vibration buffer device, the fire-fighting pipe is first placed into the second jacket 3. After placement, the first jacket 2 is moved downward by rotating the threaded rod 32. This allows the fire-fighting pipe to be positioned using the first jacket 2 and the second jacket 3, and the buffer plate 4 can clamp the pipe to ensure its stability. When the fire-fighting pipe support is vibrated by external factors, its first spring 43 will perform a certain buffer deformation, thereby achieving the purpose of anti-vibration buffering for the fire-fighting pipe in the first jacket 2 and the second jacket 3, and improving its service life. At the same time, through the setting of the base plate 5, lifting rod 51, second spring 52, limiting plate 53, nut 54 and fixing rod 55, the lifting rod 51 can be connected to the support base 1 using the nut 54. When the fire-fighting pipe support vibrates, the lifting rod 51 will rise and fall inside the fixing rod 55, and at the same time, the second spring 52 on the outside will deform to achieve the purpose of anti-vibration buffering, improving the service life of the fire-fighting pipe and having good practicality.
[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
