Description

Technical Field

[0001] This invention belongs to the field of prefabricated support and hanger technology, and specifically relates to a prefabricated support and hanger for chemical pipelines. Background Technology

[0002] In chemical production workshops, it is often necessary to transport corrosive gaseous media and toxic waste gases through chemical pipelines. Since the gaseous media being transported are relatively light, the chemical pipelines for transporting gases are generally suspended on the workshop roof using prefabricated supports and hangers.

[0003] Currently, the installation and layout of prefabricated supports and hangers requires initial positioning and layout to determine the installation position of each set of supports and hangers. Then, channel steel is installed at the corresponding positions, and finally, crossbeams are assembled. Each set of supports and hangers assembled in this way is an independent structural component. Due to installation errors, adjustments are needed after the layout is completed to improve the installation accuracy of the prefabricated supports and hangers, ensuring stable support for chemical pipelines.

[0004] However, because prefabricated supports and hangers need to be assembled and adjusted on the roof, the operation is cumbersome, time-consuming, and labor-intensive. Furthermore, since each set of supports and hangers is an independent structural component with low structural strength, it is prone to shaking during the installation of chemical pipelines, causing positional deviations and affecting the stability of the chemical pipeline support, thus impacting the safe use of the chemical pipelines. In the subsequent operation of chemical pipelines, if a malfunction occurs, such as a gas leak at the pipeline interface, the corrosive gas or toxic waste that spreads into the chemical production workshop, due to the dense distribution of personnel, could cause a major safety accident, posing a significant safety hazard.

[0005] Therefore, in response to the above problems, a prefabricated support and hanger for chemical pipelines is proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0052] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0053] like Figures 1-11 As shown, an embodiment of the present invention provides a prefabricated support and hanger for chemical pipelines, comprising: several sets of support and hanger bodies, a first series fixing component, a second series fixing component, and an end support structure.

[0054] like Figure 8 and Figure 9 As shown, the main body of the several sets of support brackets includes several sets of C-shaped frames 1 and several sets of support beams 2. The upper and lower ends of both sides of the support beams 2 are fixedly assembled with the C-shaped frames 1 by angle steel fasteners 17. The support beams 2 have positioning protrusions 204 on both sides, and the corresponding positions of the C-shaped frames 1 are provided with positioning slots 105 that match the positioning protrusions 204.

[0055] During the installation of the support beam 2, the positioning protrusions 204 on both sides of the support beam 2 can be inserted into the corresponding positioning slots 105 to achieve precise positioning of the support beam 2 on the C-frame 1. Then, the support beam 2 can be locked using the angle steel fasteners 17. This not only facilitates the precise assembly of the support beam 2 on the C-frame 1, but also improves the structural strength of the main support structure, making it safer and more reliable to use.

[0056] like Figure 5 and Figure 6 As shown, two sets of mounting plates 102 are welded and fixed on the C-frame 1, which can be used to hoist and fix the C-frame 1 to the roof of the chemical production workshop.

[0057] Multiple sets of clamps 103 are also fixedly installed on the C-frame 1, which can be used to fix chemical pipelines to the C-frame 1.

[0058] Several sets of C-shaped frames 1 are fixedly installed with lower supports 101 at their bottom, and several sets of support beams 2 are fixedly installed with upper supports 201 at their top.

[0059] like Figure 1 and Figure 2 As shown, the first series fixing assembly includes several sets of upper connecting pipes 3, and the second series fixing assembly includes several sets of lower connecting pipes 4. Flanges are welded and fixed to both ends of the sets of upper connecting pipes 3 and lower connecting pipes 4, and bolt holes matching the flanges are respectively opened on the lower support 101 and the upper support 201.

[0060] Several sets of upper connecting pipes 3 are respectively fixedly installed between the upper supports 201 on two adjacent sets of support beams 2 through flanges, and the series fixation between several sets of support beams 2 is achieved through several sets of upper connecting pipes 3.

[0061] Several sets of lower connecting pipes 4 are respectively fixedly installed between the lower supports 101 on two adjacent sets of C-shaped frames 1 through flanges, and the series fixation between several sets of C-shaped frames 1 is achieved through several sets of lower connecting pipes 4.

[0062] Specifically, before installing the supports and hangers, a corresponding number of supports and hangers can be pre-assembled on the ground using upper connecting pipe 3 and lower connecting pipe 4, according to requirements. This pre-positioning and assembly of several sets of supports and hangers on the ground saves time and effort, ensuring accurate assembly positions between sets. Subsequent roof hoisting eliminates the need for positioning and layout operations, reducing the number of installation steps and greatly facilitating subsequent roof hoisting and fixing.

[0063] At the same time, it improves the overall structural strength of the supports and hangers, so that each set of supports and hangers is no longer in an independent state. After being hoisted onto the roof, it can withstand both vertical and horizontal forces. This prevents individual supports and hangers from swaying due to horizontal forces during the installation of chemical pipelines, avoiding positional shifts and ensuring that the supports and hangers provide stable and reliable support for the chemical pipelines.

[0064] like Figures 1-4 As shown, the end support structure includes a first end bracket 5 and a second end bracket 6, both of which are T-shaped. The first end bracket 5 and the second end bracket 6 are fixedly installed between the upper connecting pipe 3 and the lower connecting pipe 4 located at both ends, respectively.

[0065] Sliding push plates 7 are installed on both the first end bracket 5 and the second end bracket 6. Support rods 703 are welded and fixed at the four corners of the push plates 7. Through holes 13 matching the support rods 703 are opened at the four corners of the first end bracket 5 and the second end bracket 6. The four sets of support rods 703 are slidably inserted into the four sets of through holes 13. The support rods 703 enable the push plates 7 to slide horizontally on the first end bracket 5 and the second end bracket 6, thereby allowing the push plates 7 to slide horizontally and fit tightly against the side wall.

[0066] The push plate 7 has a fixing hole 702. After the push plate 7 is pressed against the side wall through the fixing hole 702, the expansion bolts are used to fix the push plate 7 to the side wall, thereby achieving the pre-fixation of the entire support and hanger.

[0067] A screw cylinder 15 is welded and fixed at the center of both the first end bracket 5 and the second end bracket 6. A tightening screw 14 is threaded inside the screw cylinder 15. A bearing is fixedly installed at the center of the push plate 7. One end of the tightening screw 14 passes through the screw cylinder 15 and is rotatably connected to the bearing on the push plate 7. By rotating the tightening screw 14, the push plate 7 can be pushed and pulled to slide horizontally.

[0068] The other end of the tightening screw 14 is fixedly equipped with a throttle 1401, which allows for easy manual rotation of the tightening screw 14.

[0069] Specifically, such as Figure 3 and Figure 4 Combination Figure 11As shown, when installing the pre-assembled support frame onto the roof of the chemical workshop, the first end support 5 and the second end support 6 can be raised to the corresponding height using an electric lift 18. If the overall support frame is too long, to prevent deformation due to its own weight during the lifting process, an additional set of electric lifts 18 can be added every 10-20 meters to support the middle section of the overall support frame, thus preventing deformation and damage during installation.

[0070] Next, by rotating the tightening screw 14 using the throttle 1401, the tightening screw 14 pushes the push plates 7 on both sides to expand to both sides until both push plates 7 are firmly against the side wall. Then, expansion bolts are used to pass through the fixing holes 702 to fasten the push plates 7 to the side wall, achieving pre-fixation of the entire support frame on the roof. In this way, the entire support frame can be pre-positioned and fixed before being locked during hoisting, facilitating the precise and stable installation of the entire support frame. After pre-fixation, the mounting plates 102 on the C-shaped frame 1 are fixed to the workshop roof in sequence using expansion bolts, thus achieving the final hoisting and fixing of the entire support frame. This greatly reduces the installation difficulty of the prefabricated support frame and brings great convenience to the installation of the support frame.

[0071] The push plate 7 has several sets of strip protrusions 701 on one end face. The friction between the push plate 7 and the side wall can be increased by the several sets of strip protrusions 701, making it less likely for the push plate 7 to slide relative to the side wall.

[0072] It is worth noting that by fixing the push plate 7 to the side wall, the overall support frame is not only hoisted and fixed to the roof of the chemical workshop, but also fixed to the vertical side wall of the chemical workshop. This gives the overall support frame multiple fixing effects, greatly reducing the risk of the support frame falling and making it safer and more reliable to use.

[0073] Several sets of gas monitors 12 are fixedly installed in the middle of each set of upper connecting pipes 3. These gas monitors 12 can be used to monitor gas leaks in chemical pipelines.

[0074] Since chemical pipelines are generally spliced ​​in multiple sections, and the splicing positions are usually located between adjacent supports and hangers, by installing a gas monitor 12 in the middle of the upper connecting pipe 3, the sealing of the chemical pipeline splice can be monitored in real time. If a gas leak occurs at the splice, the gas monitor 12 can detect it in time and issue an alarm signal, prompting the production personnel in the chemical workshop to evacuate in time.

[0075] like Figure 8 Combination Figure 10As shown, the C-shaped frame 1 has a hollow structure inside, which is connected to the interior of the lower support 101. The support beam 2 has an air blowing channel 205 inside, which is connected to the interior of the hollow structure through a positioning protrusion 204.

[0076] like Figure 5 Combination Figure 10 and Figure 12 As shown, one end of the C-frame 1 and the support beam 2 is provided with a closed air inlet 16. The air inlet 16 is connected to the hollow structure and the air blowing channel 205. Through the closed air inlet 16, the C-frame 1 and the support beam 2 can blow out a closed isolation air curtain. If a toxic gas leak occurs at a chemical pipeline joint, an isolation air curtain can be formed by blowing air to temporarily isolate the toxic gas and prevent the leaked toxic gas from spreading outward and causing a safety accident.

[0077] like Figure 1 , Figure 2 and Figure 4 As shown, a liquid nitrogen storage tank 8 is fixedly connected to the bottom of the second end bracket 6, and a blower box 9 is fixedly installed at the bottom of the liquid nitrogen storage tank 8. An air guide pipe 901 is fixedly connected between the output end of the blower box 9 and the lower connecting pipe 4. The output end of the blower box 9 is connected to the interior of the lower connecting pipe 4 through the air guide pipe 901. The lower connecting pipe 4 can inject air into the hollow structure inside the C-shaped frame 1 through the lower support 101.

[0078] like Figure 7 As shown, a second solenoid valve 104 is fixedly installed between the lower support 101 and the C-shaped frame 1. The second solenoid valve 104 can control the opening and closing of the hollow structure inside the lower support 101 and the C-shaped frame 1, thereby controlling the air blowing of each set of supports and hangers.

[0079] Specifically, if the gas monitor 12 detects a toxic gas leak at a certain point in the chemical pipeline, it opens the second solenoid valve 104 at the bottom of the C-frame 1 adjacent to that location and starts the blower box 9. The blower box 9 blows air into the lower connecting pipe 4 through the air guide pipe 901. After being conducted through the lower connecting pipe 4, the air enters the two adjacent sets of C-frames 1 from the corresponding lower support 101. Then, it sprays out two sets of isolation air curtains through the air blowing port 16. The isolation air curtains prevent the spread of toxic gas and provide sufficient time for the evacuation and escape of production personnel in the chemical workshop, ensuring safe production.

[0080] In this way, the support frame can cope with accidental leaks of toxic gases during subsequent use and take corresponding measures to protect the personal safety of production personnel in the chemical workshop, which is conducive to the safe production of the chemical workshop.

[0081] like Figure 4As shown, the liquid nitrogen storage tank 8 contains liquid nitrogen. A bypass pipe 801 is fixedly connected between the liquid nitrogen storage tank 8 and the air duct 901. The interior of the liquid nitrogen storage tank 8 is connected to the interior of the air duct 901 through the bypass pipe 801, allowing liquid nitrogen to enter the interior of the air duct 901.

[0082] A third solenoid valve 8011 is fixedly installed on the bypass pipe 801. The closing of the bypass pipe 801 can be controlled by the third solenoid valve 8011, thereby controlling the supply of liquid nitrogen.

[0083] like Figure 6 and Figure 7 As shown, a lower branch pipe 1011 is fixedly connected to the bottom end of the lower support 101, and the lower branch pipe 1011 is connected to the interior of the lower support 101. A first solenoid valve 1012 is fixedly installed on the lower branch pipe 1011, and the opening and closing of the lower branch pipe 1011 can be controlled by the first solenoid valve 1012. A fire ball 1013 is fixedly installed at the bottom end of the lower branch pipe 1011, and the interior of the fire ball 1013 is connected to the interior of the lower support 101 through the lower branch pipe 1011. An opening 1014 is provided on the fire ball 1013, through which air can be blown downwards.

[0084] Specifically, because chemical production workshops contain a large number of hazardous chemical products, a fire in such a workshop would result in a major accident and cause serious environmental damage. Furthermore, firefighters would find it difficult to approach and take firefighting measures in the event of a fire. Therefore, autonomous firefighting operations in chemical workshops are of paramount importance.

[0085] When a fire occurs in the chemical workshop, the third solenoid valve 8011 can be opened and the blower box 9 can be started. This allows the liquid nitrogen inside the liquid nitrogen storage tank 8 to enter the air duct 901 through the bypass pipe 801 and quickly vaporize into low-temperature nitrogen gas. The low-temperature nitrogen gas is then conducted through the lower connecting pipe 4 to the lower support 101 at the bottom of each C-shaped frame 1. Then, the first solenoid valve 1012 is opened, allowing the low-temperature nitrogen gas to enter the fire-fighting ball 1013 through the lower branch pipe 1011, and finally sprayed evenly downwards through the opening 1014. By spraying the low-temperature nitrogen downwards, firstly, cooling is achieved; secondly, by covering the nitrogen, air can be expelled, causing the fire source to extinguish automatically, thus achieving the effect of autonomous fire suppression.

[0086] This allows the support bracket to also have an independent fire-fighting function, making it particularly suitable for hazardous locations, such as pipe support inside spaces containing flammable and explosive materials.

[0087] like Figure 10As shown, the support beam 2 has an internal air extraction channel 206, which is connected to the interior of the upper support 201. The upper connecting pipe 3 is connected to the interior of the air extraction channel 206 through the upper support 201, and the upper connecting pipe 3 can extract air from the interior of the air extraction channel 206, making the air extraction channel 206 a negative pressure state.

[0088] like Figure 6 and Figure 10 As shown, the support beam 2 is also equipped with an exhaust port, through which toxic gases leaking from inside the isolation air curtain can be extracted. The exhaust port includes a lower exhaust port 202 and a side exhaust port 203, both of which are connected to the interior of the exhaust channel 206, enabling both the lower exhaust port 202 and the side exhaust port 203 to extract leaked toxic gases.

[0089] The lower exhaust port 202 is vertically located at the bottom of the support beam 2, and can extract leaked toxic gas from the vertical direction. The side exhaust port 203 is inclined downward on one side of the support beam 2, and can extract leaked toxic gas from the side.

[0090] Specifically, such as Figure 10 Combination Figure 12 As shown, because the isolation air curtain blows from one set of supports to another, the leaked toxic gas will also flow along with the isolation air curtain from one set of supports to the other. At this time, the side exhaust port 203 on the other set of supports will draw in the toxic gas head-on, and the bottom exhaust port 202 will draw in the toxic gas vertically as it passes through the support. In this way, through two extractions, the leaked toxic gas can be effectively and completely removed, achieving efficient collection of the leaked toxic gas.

[0091] like Figures 1-3 Combination Figure 10 As shown, a fan housing 10 is fixedly installed below the first end bracket 5. An air inlet pipe 1001 is fixedly connected between the input end of the fan housing 10 and the upper connecting pipe 3. The input end of the fan housing 10 is connected to the interior of the upper connecting pipe 3 through the air inlet pipe 1001. By starting the fan housing 10, air can be drawn from the interior of the upper connecting pipe 3, and the upper connecting pipe 3 can also draw air from the interior of the air extraction channel 206, thereby drawing the toxic gas inside the isolation curtain into the interior of the air extraction channel 206 through the lower air extraction port 202 and the side air extraction port 203.

[0092] When a gas leak occurs in a chemical pipeline, both the blower box 9 and the exhaust fan box 10 are activated simultaneously. The blower box 9 blows an isolation air curtain from the support frame through the lower connecting pipe 4, isolating the leaked toxic gas. Then, the exhaust fan box 10 extracts the toxic gas from inside the isolation air curtain through the upper connecting pipe 3.

[0093] In this way, by isolating first and then extracting, the system can autonomously handle toxic gas leaks from chemical pipelines, enabling the support bracket to independently cope with various unexpected production accidents during subsequent use and effectively ensure the safe production of chemical workshops.

[0094] like Figure 3 As shown, a gas storage box 11 is fixedly connected to the bottom of the exhaust fan box 10. The gas storage box 11 is used to collect and store the collected toxic gases. An exhaust pipe 1002 is fixedly installed between the output end of the exhaust fan box 10 and the gas storage box 11. The output end of the exhaust fan box 10 is connected to the inside of the gas storage box 11 through the exhaust pipe 1002.

[0095] A one-way valve 10021 is fixedly installed on the gas outlet pipe 1002 to prevent the backflow of toxic gas collected inside the gas storage tank 11.

[0096] Specifically, the leaked toxic gas extracted by the exhaust fan box 10 can be discharged into the interior of the gas storage box 11 through the exhaust pipe 1002 for collection, thereby achieving temporary storage of the leaked toxic gas.

[0097] It is worth noting that, such as Figure 2 As shown, a bottom groove 1101 is also provided at the bottom of the gas storage box 11. A folding airbag 1102 is fixedly installed inside the bottom groove 1101. The folding airbag 1102 can automatically expand when the gas storage box 11 collects toxic gas, effectively increasing the internal capacity of the gas storage box 11 and improving the collection effect of the gas storage box 11.

[0098] An exhaust valve 1103 is installed on the gas storage tank 11. The toxic gas collected inside the gas storage tank 11 can be removed through the exhaust valve 1103 for further processing.

[0099] During assembly, the support beam 2 is first assembled and fixed on the C-frame 1 using angle steel fasteners 17. Then, the upper connecting pipe 3 and the lower connecting pipe 4 are used to connect and fix several hangers assembled from the C-frame 1 and the support beam 2 in series to form an integral hanger. The number of hangers can be adjusted arbitrarily according to the requirements.

[0100] During installation, the entire support frame is first lifted to the required height using the electric lift 18, then pre-fixed to the side wall using the push plate 7, and then fixed to the roof using the mounting plate 102. This completes the installation of the entire support frame. Finally, the chemical pipeline is fixed to the support frame using the clamp 103.

[0101] In subsequent use, if a gas leak occurs at the joint of the chemical pipeline, the blower box 9 and the exhaust fan box 10 will be activated immediately. The blower box 9, through the lower connecting pipe 4, blows out an isolation air curtain from the corresponding support and hanger to isolate the leaked toxic gas. Then, the exhaust fan box 10, through the upper connecting pipe 3, allows all supports and hangers to extract the leaked toxic gas, enabling the supports and hangers to handle hazardous gas leaks autonomously. If a fire occurs in the chemical workshop, the fire-fighting ball 1013 below the supports and hangers can also blow out low-temperature nitrogen gas for autonomous fire extinguishing, enabling the supports and hangers to autonomously respond to various hazardous situations.

[0102] Compared with the prior art, the prefabricated support and hanger for chemical pipelines of the present invention can pre-assemble several sets of supports and hangers into a whole by using the upper connecting pipe 3 and the lower connecting pipe 4. This can ensure the installation accuracy of each set of supports and hangers and guarantee the overall structural strength, providing stable and reliable support for chemical pipelines, eliminating unnecessary installation operations, and saving time and effort.

[0103] With the movable push plate 7, after the support bracket is vertically suspended and fixed to the roof, it can also be horizontally installed and fixed to the side wall, which greatly improves the stability of the prefabricated support bracket installation and makes it safer and more reliable to use.

[0104] In addition, the lower connecting pipe 4 enables each set of supports to blow out an isolation air curtain. In the event of a gas leak in the chemical pipeline, the leaked gas can be isolated to prevent the spread of toxic gas and the occurrence of a major safety accident. The upper connecting pipe 3 enables each set of supports to extract the leaked gas located inside the isolation air curtain, realizing autonomous handling after a toxic gas leak and ensuring safe production in the chemical workshop.

[0105] 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 invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0106] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
