Abstract

This utility model relates to the field of pipe support devices, and more particularly to a high-strength, earthquake-resistant metal pipe support device, comprising a pipe body; earthquake-resistant components are fitted on the exterior of both ends of the pipe body, and a support component is fitted in the middle of the pipe body. This utility model utilizes an arc-shaped limiting frame in the earthquake-resistant component to adjust its height according to the diameter of the pipe body, thereby limiting and fixing the pipe body. Then, the support component is lifted and placed in the middle of the pipe body, and its rotation adjustment provides oblique support to the pipe body. Through the combined use of the rubber vibration-damping pad inside the arc-shaped limiting frame and the support column in the support component, vibration transmission can be reduced.

Description

Technical Field

[0001] This utility model relates to the field of pipe support devices, and in particular to high-strength earthquake-resistant metal pipe support devices. Background Technology

[0002] Metal pipes are tubular objects made of metal materials, typically used to transport liquids, gases, or solids. They can also be used for electrical wiring protection, structural support, and other applications. Pipe racks are facilities used to support and fix metal pipes. They fix the pipes in a specific position, preventing displacement in any direction. They are mainly used at the starting point, ending point, branch point of the pipeline, and in areas where thermal expansion and contraction of the pipeline needs to be limited. They can withstand the weight of the pipeline, horizontal thrust, bending moment, and other forces.

[0003] Most existing pipe rack systems use unidirectional fixing, which may cause excessive displacement, shaking, or deformation of metal pipes under seismic forces. This can lead to loosening of pipe connections, failure of seals, or even cracks or ruptures in the pipes themselves, resulting in leakage of liquids or gases. If the pipes are transporting flammable, explosive, toxic, or harmful substances, the leakage could cause serious safety accidents such as fires, explosions, and poisoning, posing a huge threat to the safety of people's lives and property.

[0004] Therefore, since most of the existing pipe rack devices adopt unidirectional fixing, under the action of seismic force, the pipe connection may loosen or the seal may fail, causing liquid or gas leakage in the pipe. If the transported material is hazardous, it may cause serious safety accidents. High-strength earthquake-resistant metal pipe rack devices can be designed and vibration damping components can be installed to reduce the transmission of vibration and improve the stability of metal pipe connections. Utility Model Content

[0005] To overcome the problem that most existing pipe racks are unidirectionally fixed, which may cause pipe connections to loosen or seal to fail under seismic forces, resulting in leakage of liquid or gas inside the pipes, and potentially causing serious safety accidents if hazardous substances are being transported, a high-strength earthquake-resistant metal pipe rack device is proposed.

[0006] The technical solution of this utility model is as follows: a high-strength earthquake-resistant metal pipe support device, including a pipe body; earthquake-resistant components are fitted on the outer sides of both ends of the pipe body, and a support component is fitted in the middle of the pipe body. The earthquake-resistant component includes an I-shaped steel frame, an arc-shaped limiting frame is provided above the I-shaped steel frame, and a rubber vibration isolation pad is fixed to the inner side of the arc-shaped limiting frame. The support component includes an arc-shaped support frame, a U-shaped frame is fixed to the middle of the outer side of the arc-shaped support frame, a support column is provided on the side of the U-shaped frame away from the arc-shaped support frame, a first rotating stud is passed through the connection between the support column and the U-shaped frame, and the support column is rotatably connected to the U-shaped frame through the first rotating stud. A fixing plate is provided on the end of the support column away from the U-shaped frame, a second rotating stud is passed through the connection between the fixing plate and the support column, and the fixing plate is rotatably connected to the support column through the second rotating stud.

[0007] Furthermore, each end of the arc-shaped limiting frame is fixedly connected to a rectangular plate, and a rectangular sleeve is fitted over the rectangular plate. The lower end of the rectangular sleeve is fixedly connected to the upper end of the I-shaped steel frame.

[0008] Furthermore, locating pins are symmetrically provided on both sides of the connection between the rectangular sleeve and the rectangular plate, and multiple sets of locating holes are vertically symmetrically opened on both sides of the rectangular plate. The locating pins pass through the rectangular sleeve and are positioned and connected to the rectangular plate through the locating holes.

[0009] Furthermore, two sets of mounting holes are horizontally provided below the I-shaped steel frame.

[0010] Furthermore, the arc-shaped support frame is arranged symmetrically in the horizontal direction, and connecting plates are symmetrically fixed at both ends of the arc-shaped support frame.

[0011] Furthermore, each pair of horizontally symmetrically arranged connecting plates has a mounting stud in the middle, and mounting nuts are threaded onto the outer walls of both ends of the mounting stud.

[0012] Furthermore, a first fixing nut is threaded onto the outer wall of both ends of the first rotating stud, and a second fixing nut is threaded onto the outer wall of both ends of the second rotating stud. Fixing holes are provided on the fixing plate.

[0013] The beneficial effects of this utility model are as follows: By setting an arc-shaped limiting frame whose height can be adjusted according to the diameter of the pipe body, it can accurately adapt to pipes of different specifications. Utilizing the fitting and limiting effect of the arc-shaped structure with the pipe body, combined with the rubber vibration isolation pad at its lower end, under seismic conditions, it not only achieves stable limiting and fixing of the pipe body but also effectively buffers and absorbs vibration energy, reducing the transmission of vibration along the pipe support to the pipe body, significantly reducing the displacement, swaying, and deformation amplitude of the pipe caused by vibration. The support component is located in the middle of the pipe body and can be rotated and adjusted to achieve oblique support for the pipe body, forming a multi-angle, multi-directional support and limiting structure with the arc-shaped limiting frame. This combined support and limiting method, under seismic action, can achieve stable limiting and fixing of the pipe body through the rigid support of the support column and the rubber vibration isolation pad. The flexible buffering mechanism effectively disperses the seismic forces on the pipeline, further enhancing the limiting and fixing effect on the pipeline. This greatly reduces the risk of pipeline rupture and leakage, ensuring the safety of transported substances such as gas, water, and oil within the pipeline. It also prevents secondary disasters such as fires, explosions, and poisoning caused by leaks, providing reliable protection for people's lives and property. Furthermore, the coordinated work of the arc-shaped limiting frame and the support components ensures the stability of the connection between the pipeline and the pipe rack, as well as between the various components of the pipe rack. During an earthquake, the aforementioned limiting and support structures can effectively prevent loosening or detachment of connections, maintaining the integrity of the pipeline system. This ensures that the pipeline system can quickly resume operation after an earthquake, reducing maintenance costs and downtime, and improving the reliability and practicality of the pipeline system.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-5 As shown, this utility model provides an embodiment: a high-strength earthquake-resistant metal pipe support device, including a pipe body 1; earthquake-resistant components are fitted on the outer sides of both ends of the pipe body 1, and a support component is fitted in the middle of the pipe body 1. The earthquake-resistant components include an I-beam steel frame 201, an arc-shaped limiting frame 202 is provided above the I-beam steel frame 201, and a rubber vibration isolation pad 203 is fixedly connected to the inner side of the arc-shaped limiting frame 202. The support component includes an arc-shaped support frame 301, a U-shaped frame 305 is fixedly connected to the middle of the outer side of the arc-shaped support frame 301, and a support column 308 is provided on the side of the U-shaped frame 305 away from the arc-shaped support frame 301. A first rotating stud 306 passes through the connection between the support column 308 and the U-shaped frame 305. The support column 308 is connected to the first rotating stud 306. The support column 308 is rotatably connected to the U-shaped frame 305. A fixing plate 309 is provided at the end of the support column 308 away from the U-shaped frame 305. A second rotating stud 310 is provided at the connection between the fixing plate 309 and the support column 308. The fixing plate 309 is rotatably connected to the support column 308 through the second rotating stud 310. According to the diameter of the pipe body 1, the arc-shaped limiting frame 202 in the anti-vibration component is height adjusted and the pipe body 1 is limited and fixed. Then, the support component is picked up and placed in the middle of the pipe body 1. The support component is rotated and adjusted to provide oblique support for the pipe body 1. Thus, the transmission of vibration can be reduced by the cooperation of the rubber vibration isolation pad 203 on the inner side of the arc-shaped limiting frame 202 and the support column 308 in the support component.

[0022] Please see Figure 3In this embodiment, a rectangular plate 204 is fixedly connected to each end of the arc-shaped limiting frame 202. A rectangular sleeve 205 is fitted over the rectangular plate 204. The lower end of the rectangular sleeve 205 is fixedly connected to the upper end of the I-shaped steel frame 201. Positioning pins 206 are symmetrically provided on both sides of the connection between the rectangular sleeve 205 and the rectangular plate 204. Multiple sets of positioning holes 207 are vertically symmetrically opened on both sides of the rectangular plate 204. The positioning pins 206 pass through the rectangular sleeve 205 and are positioned and connected to the rectangular plate 204 through the positioning holes 207. The lower end of the I-shaped steel frame 201... Two sets of mounting holes 208 are provided horizontally. The pipe body 1 is passed between the I-shaped steel frame 201 and the arc-shaped limiting frame 202. Finally, according to the diameter of the pipe body 1, the rectangular plate 204 is moved vertically along the rectangular sleeve 205 by adjusting the positioning pin 206 until the rubber vibration isolation pad 203 is close to the outer wall of the pipe body 1 and is limited. After confirming that there is no problem, the positioning pin 206 is picked up and passed through the rectangular sleeve 205 and positioned and connected to the rectangular plate 204 through the positioning hole 207.

[0023] Please see Figures 4-5 In this embodiment, the arc-shaped support frame 301 is arranged symmetrically in the horizontal direction. The two ends of the arc-shaped support frame 301 are symmetrically fixed with connecting plates 302. A mounting stud 303 is inserted through the middle of each pair of horizontally symmetrical connecting plates 302. The outer walls of the mounting studs 303 are threaded with mounting nuts 304. The outer walls of the first rotating stud 306 are threaded with first fixing nuts 307. The outer walls of the second rotating stud 310 are threaded with second fixing nuts 311. Fixing holes 312 are opened on the fixing plate 309. After the end of the pipe body 1 is fixed, the two sets of arc-shaped support frames 301 are picked up and placed symmetrically on the outer wall of the pipe body 1. Then, the mounting studs 303 are picked up, passed through the connecting plates 302, and the mounting nuts 304 are tightened.

[0024] According to the required installation location of the pipe body 1, first move the I-beam steel frame 201 to the corresponding location. Then, pass the ground nail through the mounting hole 208 to fix the I-beam steel frame 201 in the appropriate position. Next, pass the pipe body 1 between the I-beam steel frame 201 and the arc-shaped limiting frame 202. Finally, according to the diameter of the pipe body 1, adjust the positioning pin 206 and move the rectangular plate 204 vertically along the rectangular sleeve 205 until the rubber vibration isolation pad 203 is close to the outer wall of the pipe body 1 for limiting operation. After confirming that everything is correct, pick up the positioning pin 206, pass it through the rectangular sleeve 205 and position it to the rectangular plate 204 through the positioning hole 207. After the end of the pipe body 1 is fixed, pick up the two sets of arc-shaped support frames 301 and place them symmetrically on the outer wall of the pipe body 1. Then, pick up the mounting stud 303, pass it through the connecting plate 302, and tighten the mounting nut 304. Then, according to the terrain of the location of the pipe body 1, loosen the first fixing screw in sequence. The first fixing nut 307 and the second fixing nut 311 allow the support column 308 to rotate to a suitable angle via the first rotating stud 306 and the U-shaped frame 305. Simultaneously, the fixing plate 309 is rotatably connected to the support column 308 via the second rotating stud 310, ensuring that the fixing plate 309 remains parallel to the ground. After continuous rotation and adjustment, the fixing plate 309 is brought into contact with the ground. The first fixing nut 307 and the second fixing nut 311 can then be tightened sequentially. Finally, a ground nail is inserted through the fixing hole 312 to reinforce the final adjusted position of the fixing plate 309, allowing the support column 308 to provide oblique support to the pipe body 1. Thus, during use, the arc-shaped limiting frame 202, in conjunction with the rubber vibration isolation pad 203, provides stable fixation to the pipe body 1 and effectively buffers and absorbs vibration energy, reducing the transmission of vibration along the I-beam steel frame 201 to the pipe body 1. Simultaneously, the arc-shaped limiting frame 202, together with the support column 308, provides multi-directional support to the pipe body 1, effectively dispersing the seismic force experienced by the pipe body 1.
