Description

Technical Field

[0001] This invention relates to the field of fireproof belt installation technology for gas pipelines, specifically to an installation mechanism for fireproof belts for pipelines. Background Technology

[0002] To protect the environment, reduce pollution, and minimize energy consumption, a natural gas high-temperature heating system has been used instead of the traditional kerosene heating system in the copper strip rolling process. However, the gas transportation process requires the use of numerous pipelines. After prolonged use, these pipelines are susceptible to corrosion from rainwater and ambient gases, leading to rust, gas leaks, and fire hazards, threatening equipment, property, and the safety of workers in the production area. Fire-resistant tape is typically used for protection. While fire-resistant tape is spirally wound around the pipeline, commonly used winding devices are usually bulky, and the pipeline needs constant movement. For gas pipelines with large lengths and diameters, this requires a significant area for winding. Therefore, we propose an installation mechanism for fire-resistant tape on pipelines. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a fireproof strip for pipelines and an installation mechanism for the fireproof strip. The fireproof strip is spirally wrapped around the outside of the pipeline through a high-temperature adhesive layer, providing comprehensive sealing protection for the pipeline, reducing the corrosive effects of rainwater and ambient gases, and reducing the risk of rust and gas leakage. The fireproof layer can play a fireproof role when a fire occurs due to pipeline rupture and gas leakage, and reduce the speed of fire spread. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fireproof strip for pipelines, comprising a fireproof strip spirally wound on a pipeline, wherein the fireproof strip is provided with a high-temperature adhesive layer, a partition layer, a reinforcing layer, a fireproof layer and an outer layer in sequence from bottom to top, and a release paper layer is provided on the outer surface of the outer layer. When the fireproof strip is wound into a fireproof strip roll, the release paper layer and the high-temperature adhesive layer are in contact and connected. When the fireproof strip is wound on the outer surface of the pipeline, it is sealed and connected to the outer surface of the pipeline through the high-temperature adhesive layer.

[0005] As a preferred embodiment of the present invention, the reinforcing layer includes a reinforcing metal mesh layer disposed between the partition layer and the fireproof layer, wherein flame-retardant particles are uniformly disposed between the mesh openings of the reinforcing metal mesh layer.

[0006] As a preferred embodiment of the present invention, the fireproof layer is an asbestos cloth layer disposed between the reinforcing metal mesh layer and the outer layer.

[0007] As a preferred embodiment of the present invention, the lower surface of the asbestos cloth layer is uniformly provided with grooves, and aerosol microcapsules are disposed in the grooves.

[0008] The present invention also provides the following technical solution: an installation mechanism for a pipeline fireproof strip, used to install the above-mentioned pipeline fireproof strip onto a gas pipeline, comprising a spiral frame, wherein the inner surface of the spiral frame is uniformly provided with wheel grooves, and a drive wheel is rotatably provided on the inner surface of the wheel grooves. The drive wheel is connected to a drive mechanism installed on the outer side of the spiral frame. When installing the fireproof strip, the spiral frame is sleeved on the outer side of the pipeline and the drive mechanism drives the drive wheel to rotate and spiral forward around the outer surface of the pipeline. A first fixing frame is provided at the tail end of the outer surface of the spiral frame, and a release shaft for placing the wound fireproof strip is provided on the first fixing frame. A through groove is provided on the spiral frame near the release shaft, and a pressure wheel for pressing the fireproof strip onto the pipeline is rotatably provided in the through groove.

[0009] As a preferred technical solution of the present invention, a mounting frame and electromagnets are used instead of a drive mechanism for driving the drive wheel to rotate. The mounting frame includes a sliding frame slidably mounted on a base plate. A circular groove is opened on the side surface of the sliding frame, and a plurality of electromagnets are evenly arranged in the circular groove. An iron block is fixedly mounted at the first end of the outer surface of the spiral frame. When installing the fireproof strip, the pipe passes through the circular groove and is coaxially mounted with the circular groove. The spiral frame is sleeved on the outside of the pipe. By sliding the sliding frame and sequentially switching the plurality of electromagnets, the iron block is attracted, causing the spiral frame to move spirally on the outside of the pipe to complete the spiral winding of the fireproof strip.

[0010] As a preferred embodiment of the present invention, two sliding grooves are symmetrically opened on both sides of the upper surface of the base plate, and a drive screw is rotatably arranged in each of the two sliding grooves. A drive motor is installed on the side surface of the base plate, and the output shaft of the drive motor passes through the sliding groove and is connected to the drive screw. The bottom end of the sliding frame is slidably arranged in the sliding groove and has a screw hole for threaded connection with the drive screw.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: The fireproof tape is spirally wrapped around the outside of the pipe using a high-temperature adhesive layer, providing comprehensive sealing protection and reducing the corrosive effects of rainwater and ambient gases, thus lowering the risk of rust and gas leaks. Simultaneously, a fireproof layer is installed inside the fireproof tape, which can play a fire-prevention role in the event of a fire caused by a pipe rupture or gas leak, slowing the spread of fire and buying time for extinguishing it, thereby reducing fire hazards to a certain extent. The installation mechanism of the fireproof tape allows for quick installation onto the gas pipeline. Driven by a drive wheel, the spiral frame spirals around the pipe, wrapping the fireproof tape around its outside. This method is suitable for the automatic placement of fireproof tape on longer pipelines, is simple to operate, highly automated, and improves work efficiency. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7 This invention provides a technical solution: a fireproof strip for pipelines, comprising a fireproof strip 1 spirally wound around a pipeline. The fireproof strip 1, from bottom to top, comprises a high-temperature adhesive layer 11, a partition layer 12, a reinforcing layer, a fireproof layer, and an outer layer 18. The high-temperature adhesive layer 11 is preferably an inorganic high-temperature adhesive, capable of withstanding temperatures of 400-1000℃. Even in the event of a pipeline rupture or fire, the fireproof strip can still function normally, preventing the fire from spreading to undamaged areas. Simultaneously, the inorganic high-temperature adhesive also acts as a sealant, isolating moisture and slowing pipeline corrosion. The partition layer 12 separates the high-temperature adhesive layer 11 from the reinforcing layer and can be a common fireproof cloth such as basalt fiber fireproof cloth or acrylic cotton fiber fireproof cloth. The heating layer is used to improve the overall strength of the fireproof strip, preventing damage from external forces during prolonged use, thereby extending the service life of the fireproof cloth.

[0022] The outer surface of the outer layer 18 is provided with a release paper layer 19. The outer layer 18 can be made of waterproof cloth to improve the waterproof sealing effect. The outer surface of the outer layer 18 is smooth and easy to separate from the release paper layer 19.

[0023] When the fireproof strip 1 is wound into a fireproof strip roll, the release paper layer 19 is in contact with the high-temperature adhesive layer 11 to isolate the outer layer 18 and the high-temperature adhesive layer 11. When the fireproof strip 1 is wrapped around the outer surface of the pipe, it is sealed to the outer surface of the pipe through the high-temperature adhesive layer 11. The fireproof strip 1 is spirally wrapped around the outside of the pipe through the high-temperature adhesive layer 11, providing comprehensive sealing protection for the pipe, reducing the corrosive effects of rainwater and ambient gases, and reducing the risk of rust and gas leakage. At the same time, a fireproof layer is also set inside the fireproof strip 1, which can play a fireproof role when a fire occurs due to pipe rupture and gas leakage, reduce the speed of fire spread, buy time for fire extinguishing, and reduce fire hazards to a certain extent.

[0024] In a preferred embodiment, the reinforcing layer includes a reinforcing metal mesh layer 13 disposed between the partition layer 12 and the fireproof layer. The reinforcing metal mesh layer 13 is preferably a metal mesh made of aluminum alloy, used to improve the overall strength of the fireproof strip.

[0025] In a further preferred embodiment, flame-retardant particles 14 are uniformly arranged between the mesh openings of the reinforced metal mesh layer 13 to further improve the fireproof effect of the fireproof strip 1 and reduce fire losses.

[0026] In a preferred embodiment, the fireproof layer is an asbestos cloth layer 15 disposed between the reinforcing metal mesh layer 13 and the outer layer 18, or it can be a silicone rubber coated glass fiber cloth layer, etc. It is resistant to high temperature, not easily fueled, and can effectively block the spread of fire.

[0027] In a further preferred technical solution, the lower surface of the asbestos cloth layer 15 is uniformly provided with grooves 16, and aerosol microcapsules 17 are disposed in the grooves 16. The aerosol microcapsules 17 are filled with aerosol fire extinguishing agent. When the aerosol microcapsules are melted by high temperature during a fire, they can release the aerosol fire extinguishing agent, which generates a fire extinguishing agent with fire extinguishing effect through combustion, thereby further improving the fire protection performance.

[0028] Fireproof tape 1 is spirally wound onto the pipeline. Commonly used winding devices are usually large in size, and the pipeline needs to be constantly moved. For gas pipelines with large length and diameter, a large area needs to be occupied for winding. Therefore, the present invention also provides the following technical solution: an installation mechanism for pipeline fireproof tape, used to install the above-mentioned pipeline fireproof tape onto the gas pipeline, including a spiral frame 2. The inner surface of the spiral frame 2 is evenly provided with wheel grooves 21. The inner surface of the wheel grooves 21 is rotatably provided with a drive wheel 22. The drive wheel 22 is connected to a drive mechanism installed on the outside of the spiral frame 2. The drive mechanism can be a motor installed on the spiral frame 2. The output shaft of the motor is connected to the drive wheel 22 through a transmission chain or other transmission mechanism. When the spiral frame 2 is used to install the fireproof tape 1, it is sleeved on the outside of the pipeline and the drive mechanism drives the drive wheel 22 to rotate and spiral forward around the outer surface of the pipeline, thereby spirally winding the fireproof tape 1 onto the outside of the pipeline.

[0029] The screw frame is also equipped with a built-in battery for powering the motor, preferably a removable and rechargeable lithium-ion battery, and a control switch connecting the motor and the built-in battery is also provided.

[0030] Specifically, a first fixing frame 23 is provided at the tail end of the outer surface of the spiral frame 2. A release shaft 24 for placing the wound fireproof tape 1 is provided on the first fixing frame 23. The fireproof tape roll formed by the fireproof tape 1 is rotatably mounted on the release shaft 24 via a sleeve or similar device. A through groove 27 is provided on the spiral frame 2 near the release shaft 24. A pressure roller 28 is rotatably mounted in the through groove 27 to press the fireproof tape 1 tightly onto the pipe. After the spiral frame 2 is fitted onto the pipe, one end of the fireproof tape roll is torn open, and the high-temperature adhesive layer 1 at the end is exposed. 1. Passing through the through groove 27 and bonded to the pipe, the release paper layer 19 at the end is torn open and placed above the pressure roller 28. The motor drives the drive wheel 22 to rotate, causing the spiral frame 2 to spiral forward around the pipe. During the forward movement, the fireproof tape roll also rotates continuously and is spirally wrapped and bonded to the pipe. During the bonding process, the fireproof tape is pressed tightly by the pressure roller 28, so that the high-temperature adhesive layer is firmly bonded to the pipe surface. It does not require the use of large equipment to move the pipe, nor does it require a special workshop for the installation of the fireproof tape 1, reducing space occupation and making it more convenient to use.

[0031] Optionally, a separator bar is also provided at the through groove 27 to separate the release paper layer 19 from the main body of the fireproof strip 1.

[0032] Optionally, when the fireproof strip 1 is wrapped around the pipe, the distance it advances with each rotation is half the width of the fireproof strip 1. That is, after the fireproof strip 1 is completely wrapped around the pipe, it consists of two layers of bonded fireproof strip 1 on the pipe. By setting up double-layer fireproof strip 1, its fireproof, sealing and corrosion-resistant performance is further improved.

[0033] In a preferred embodiment, a second fixed frame 25, opposite to the first fixed frame 23, is fixedly installed on the outer side of the spiral frame 2 near the through groove 27. A take-up shaft 26 for winding the release paper layer 19 is provided on the second fixed frame 25. An arc-shaped clamp for clamping the end of the release paper layer 19 can be provided on the outer side of the take-up shaft 26. A motor for driving the take-up shaft 26 to rotate is provided on the first fixed frame 23. The spiral frame 2 spirals forward, and the motor on the fireproof belt 1 drives the take-up shaft 26 to rotate and roll up the release paper layer 19 to facilitate subsequent recycling or processing.

[0034] For preferred options, please refer to [link / reference]. Figure 5 The drive wheel 22 includes a wheel frame and an outer wheel rim 221. The outer wheel rim 221 is made of rubber or silicone, etc., and multiple extrusion grooves 222 are evenly opened on the outer wheel rim 221. The material around the extrusion grooves 222 is relatively soft. During the process of the drive wheel 22 moving around the outer wall of the pipe, the extrusion grooves 222 are continuously squeezed, squeezing out the air inside, thereby forming a large adsorption force with the outer wall of the pipe, which improves the stability of the spiral frame 2 during movement.

[0035] This invention also provides another embodiment, please refer to the following for details. Figure 6 and Figure 7This embodiment is largely the same as the above embodiment, except that: a mounting frame 3 and electromagnets 37 are used instead of the drive mechanism for rotating the drive wheel 22, allowing the drive wheel 22 to rotate freely within the wheel groove, and providing support and reducing friction when the spiral frame 2 rotates. The mounting frame 3 includes a sliding frame 35 slidably mounted on the base plate 31. A circular groove 36 is provided on the side surface of the sliding frame 35, and several electromagnets 37 are evenly arranged in the circular groove 36. An iron block 29 is fixedly mounted at the first end of the outer surface of the spiral frame 2. When installing the fireproof strip 1, the pipe passes through the circular groove 36 and is coaxially mounted with the circular groove 36. The spiral frame 2 is fitted onto the outside of the pipe. By sliding the sliding frame 35 and sequentially switching the several electromagnets 37, the iron block 29 is attracted, causing the spiral frame 2 to move spirally on the outside of the pipe to complete the spiral winding of the fireproof strip 1. Specifically, after the spiral frame 2 is installed, the sliding frame 35 moves along the mounting frame 3. The track moves forward at a constant speed. Electromagnets 37, evenly arranged in the circular groove 36, open and close sequentially. The electromagnet 37 closest to the ferrous block 29 and located in its rotation direction opens first, attracting the ferrous block 29 to move towards it, thereby driving the spiral frame 2 to rotate around the pipe a certain distance. During this process, the sliding frame 35 continues to drive the electromagnets 37 forward, thus making the spiral frame 2 spiral forward. After the ferrous block 29 moves to the position of the electromagnet 37, the electromagnet 37 closes, and the next electromagnet 37 opens. The ferrous block 29 is then attracted by the next electromagnet 37 and spirals forward. Afterward, under the attraction of several electromagnets 37, it spirals forward around the outer wall of the pipe, completing the installation of the fireproof strip 1. Similarly, it does not require the use of large equipment to move the pipe; it only needs to be placed on the mounting frame 3. Compared with the above embodiment, it does not require the installation of motors and batteries on the spiral frame 2, so there is no need to worry about the battery life during use.

[0036] During the movement of the screw frame 2 and the sliding frame 35, the electromagnet 37, the ferrous block 29, the first fixed frame 23, the second fixed frame 25, etc., do not come into contact to avoid collision and damage.

[0037] In a preferred embodiment, two symmetrical grooves 32 are formed on both sides of the upper surface of the base plate 31. A drive screw 34 is rotatably installed in each of the two grooves 32. A drive motor 33 is installed on the side surface of the base plate 31. The output shaft of the drive motor 33 passes through the groove 32 and is connected to the drive screw 34. The bottom end of the sliding frame 35 is slidably installed in the groove 32 and has a threaded hole that is threaded to the drive screw 34. The drive motor 33 drives the drive screw 34 to rotate, causing the sliding frame 35 to drive the electromagnet 37 to move at a uniform speed, thereby completing the winding arrangement of the fireproof strip 1.

[0038] The motors, drive motors 33, electromagnets 37, etc. used in this invention are all commonly used electronic components in the prior art. They are all electrically connected to external or control switches located in corresponding components. Their specific structures, working principles, and circuit connections are all known technologies and will not be described in detail here.

[0039] An optional technical solution is that pipe supports 38 are fixedly provided at both ends of the base plate 31 to support the pipes. The placement groove on the pipe support 38 is coaxial with the circular groove 36. The length of the entire base plate 31 can be set according to the length of the pipe.

[0040] In a preferred embodiment, the spiral frame 2 has 1-1.5 spiral turns, so that the spiral frame 2 can be stably fitted onto the outer wall of the pipe during rotation.

[0041] All parts not disclosed in this invention are prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
