[0040] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0041] Example 1
[0042] The vertical panels used to separate different areas inside a rail vehicle are called partitions. Existing partitions on rail vehicles only meet fire protection requirements on one side, and the fire protection performance is not good enough.
[0043] like Figure 1 As shown, this embodiment provides a fireproof partition, including a partition main body structure, the inner wall of the partition main body structure is provided with an inner fireproof structure, and the outer wall of the partition main body structure is provided with an outer fireproof structure, and the inner fireproof structure and the outer fireproof structure are used for internal and external double-sided fire protection of the partition main body structure.
[0044] The present application provides fire protection for both sides of the partition main structure by respectively setting an inner fire protection mechanism and an outer fire protection structure on the inner and outer sides of the partition main structure, so that both sides of the partition meet the requirements of thermal insulation and integrity, thereby improving the fire protection effect.
[0045] Specifically, in this embodiment, the outer fire protection structure includes a first ceramic fiber layer 7, a first fire protection phenolic board layer 6 and a first steel plate layer 5, and the outer side wall of the partition wall main body structure is sequentially provided with the first ceramic fiber layer 7, the first fire protection phenolic board layer 6 and the first steel plate layer 5.
[0046] In this embodiment, the inner fireproof structure includes a second fireproof phenolic board layer 11 and a second steel plate layer 9, and the inner wall of the partition main body structure is sequentially provided with the second fireproof phenolic board layer 11 and the second steel plate layer 9.
[0047] In this embodiment, the partition wall main body structure includes an inner frame 12 and an outer frame 8 connected to each other. A second ceramic fiber layer 16 is provided at the connection between the inner frame 12 and the outer frame 8. The second ceramic fiber layer 16 can separate the outer frame 8 and the inner frame 12 to prevent heat conduction.
[0048] In this embodiment, the inner frame 12, the outer frame 8, the first steel plate layer 5 and the second steel plate layer 9 are all made of stainless steel.
[0049] When the outer side of the fireproof partition is exposed to fire: the first steel plate layer 5 made of stainless steel can ensure the integrity of the partition and ensure that the partition will not be burned through for a long time; the first fireproof phenolic plate layer 6 not only plays a low-temperature heat insulation role, but also ensures the flatness of the partition surface; the first ceramic fiber layer 7 can block high-temperature heat and ensure that the temperature on the driver's cab side meets the fire protection standards; the outer frame 8 made of stainless steel can ensure the rigidity of the partition itself.
[0050] When the interior of the fireproof partition is exposed to fire, the stainless steel second steel plate layer 9 ensures the partition's integrity, preventing it from burning through for a long time. The second fireproof phenolic plate layer 11 not only provides low-temperature insulation but also ensures the partition's surface flatness. The stainless steel inner frame 12 ensures the partition's rigidity. The first fireproof expansion strip 13, upon thermal expansion, seals the gap between the partition door and the door frame.
[0051] The partition structure of the present application is universal, can improve design efficiency, enhance the standardization and modularization of design, and meet the requirements of multiple fire protection standards.
[0052] Example 2
[0053] Partitions are vertical panels used to separate different areas within rail vehicles. Existing partitions in rail vehicle driver cabs only meet fire protection requirements on one side, resulting in inadequate fire protection performance. Furthermore, different fire protection standards correspond to different fire resistance requirements for partition structures, highlighting the importance of fire protection for partition structures. However, due to the varying specific requirements for partition structure fire protection in different fire protection standards, significant manpower and material resources are required during the partition design phase to redesign the partition structure and conduct repeated verification and testing, impacting the design and production schedule.
[0054] In this regard, we provide a technical solution in this embodiment to solve this problem, and refer to Figure 2-Figure 5 , as shown below:
[0055] like Figure 2 As shown, this embodiment provides a rail vehicle driver's cab partition, which is made of the fireproof partition in Example 1, and includes a left partition 1 on the left side, a right partition 2 on the right side, a door frame assembly 4 in the middle, and a partition top plate 3 on the top. The door frame assembly 4 is located between the left partition 1 and the right partition 2. The left partition 1, the right partition 2, the door frame assembly 4, and the partition top plate 3 are all made of fireproof partitions, which are then spliced and connected to form the driver's cab partition of this application. During design, the fireproof partition in Example 1 is used as a partition plate material, which is used as a raw material for making the rail vehicle driver's cab partition in this embodiment, and can be used to make the driver's cab partition. When the manufactured driver's cab partition is installed in the rail vehicle, the inner side of the fireproof partition is located on the side closer to the driver's cab, and the outer side of the fireproof partition is located on the side closer to the passenger compartment.
[0056] The rail vehicle driver's cab partition wall of the present application is made of the fireproof partition wall in Example 1. As a partition wall of the driver's cab, it can achieve double-sided fire protection. When one side of the driver's cab is on fire or one side of the passenger compartment is on fire, both sides of the partition wall meet the thermal insulation and integrity requirements, thereby improving the fire protection effect.
[0057] Specifically, in this embodiment, the door frame assembly 4 includes a door frame and a partition door, and the partition door is also made of a fireproof partition.
[0058] In this embodiment, it should be noted that, in order to ensure free access between the driver's cab and the passenger compartment, a partition door is provided in the middle of the partition wall of the driver's cab. Since the partition door is not fixed and will be frequently opened or closed, in order to ensure the fireproof performance between the top of the partition door and the door frame, a groove 21 is provided at the top of the partition door. The groove 21 is provided along the length direction of the top surface of the partition door. A first fireproof expansion strip 13 is provided in the groove 21. The first fireproof expansion strip 13 can be used for sealing between the top surface of the partition door and the inner top surface of the door frame after expansion due to heat.
[0059] Specifically, a third steel plate layer 20 is arranged on the top of the partition door. The third steel plate layer 20 is formed by bending. The two ends of the third steel plate layer 20 are respectively sealed with the first steel plate layer 5 and the second steel plate layer 9 to surround and seal the top of the partition door. The third steel plate layer 20 is combined with the top surface of the partition door to form a concave shape. The inner wall of the third steel plate layer 20 and the top surface of the partition door are filled with fire-proof expansion glue 15. The outer side of the third steel plate layer 20 has a groove 21, and the first fire-proof expansion strip 13 is arranged in the groove 21. The first fire-proof expansion strip 13 can be used for sealing between the entire top surface of the partition door and the inner top surface of the door frame after heat expansion, and can seal the gap between the partition door and the door frame.
[0060] It should be noted that what preferably used in the present embodiment is the first fireproof expansion adhesive strip 13 as fireproof sealing material, certainly also can select other fireproof sealing material to be used for the fireproof seal between partition door and the doorframe.The end surface of the 3rd steel plate layer 20 need guarantee flatness, and the end surface of the first fireproof expansion adhesive strip 13 should be in same plane with the end surface of the 3rd steel plate layer 20, to ensure the flatness on partition door top, make and combine more strict between partition door and the doorframe.Simultaneously, the two sides of partition also should guarantee vertical planeness, and can guarantee that rigidity and the flatness of partition whole body satisfy design and production requirement fully by outer skeleton 8, inner skeleton 12, the first fireproof phenolic board layer 6 and the second fireproof phenolic board layer 11.In the present embodiment, the thickness of slab of the first fireproof phenolic board layer 6 and the second fireproof phenolic board layer 11 is all preferably designed to 8mm.
[0061] It should be noted that the cross-sectional structure of the third steel plate layer 20 is as follows: Figure 5 As shown, the third steel plate layer 20 is used to surround the top of the sealed partition door. The third steel plate layer 20 has two ends, namely a first end and a second end. The first end of the third steel plate layer 20 is connected to one end of the first steel plate layer 5 to achieve sealing at the connection, and the second end of the third steel plate layer 20 is connected to one end of the second steel plate layer 9 to achieve sealing at the connection. After the first steel plate layer 5, the second steel plate layer 9 and the third steel plate layer 20 are sealed and connected, the sealed protection of the partition door is achieved.
[0062] In this embodiment, the preferred embodiment is that the first steel plate layer 5, the second steel plate layer 9 and the third steel plate layer 20 are all made of stainless steel and have the same thickness. In this embodiment, the first steel plate layer 5, the second steel plate layer 9 and the third steel plate layer 20 are all 1 mm thick.
[0063] It should be noted that the third steel plate layer 20 can be an integral structure with the first steel plate layer 5, or the third steel plate layer 20 can also be an integral structure with the second steel plate layer 9, or a part of the third steel plate layer 20 can be an integral structure with the first steel plate layer 5 and the other part can be an integral structure with the second steel plate layer 9, and the sealing can be achieved by welding the interruption of the third steel plate layer 20.
[0064] Since the third steel plate layer 20 is installed correspondingly on the top of the partition door and surrounds and seals the top of the partition door, after the third steel plate layer 20 is installed correspondingly, it is combined with the top surface of the partition door to form a concave shape, such as Figure 3 As shown, a first fastener 14 is designed to fasten the third steel plate layer 20 , and the third steel plate layer 20 is connected to the top of the partition door through the first fastener 14 . The first fastener 14 can preferably be a screw or a bolt.
[0065] It should be noted that the second fireproof phenolic plate layer 11 and the second steel plate layer 9 in the inner fireproof structure are fastened to the inner frame 12 by a second fastener 10, and the second fastener 10 is preferably a screw or a bolt.
[0066] The left partition wall 1 and the right partition wall 2 of the driver's cab are symmetrical structures. Ventilation holes are provided on both the left partition wall 1 and the right partition wall 2. The ventilators are symmetrically arranged and located at the lower part of the partition wall of the driver's cab. The ventilators are used to ensure ventilation in the driver's cab. In order to ensure the fire prevention effect at the ventilators at the same time, fire grilles 17 are installed in the ventilators. The fire grilles 17 play a ventilation role when the vehicle is operating normally. When heated, the fire grilles 17 expand and block the gaps, thereby playing a flame retardant role in isolating the fire source.
[0067] Specifically, the fire grille 17 has multiple ventilation holes, and the inner walls of all ventilation holes are provided with second fire-proof expansion strips (not shown in the figure). The second fire-proof expansion strips can block the ventilation holes after being heated to achieve sealing, thereby playing a fire-proof role.
[0068] In order to facilitate the fixed installation of the fire grille 17, a grille baffle frame 18 is designed. The grille baffle frame 18 is correspondingly arranged on the periphery of the fire grille 17, and the fire grille 17 is fixedly installed in the ventilation opening through the grille baffle frame 18.
[0069] like Figure 4 As shown, the present application also provides a partition frame 19, which is arranged between the grille baffle frame 18 and the inner wall of the vent. The partition frame 19 plays a barrier role, which can prevent the fire grille 17 and the grille baffle frame 18 from directly contacting the partition wall main structure and forming a barrier layer therebetween.
[0070] The rail vehicle driver's compartment partition wall of this application has a double-sided fire protection function, specifically as follows:
[0071] When the passenger compartment side is affected by fire: the first steel plate layer 5 made of stainless steel can ensure the integrity of the partition wall and ensure that the partition wall will not be burned through for a long time; the first fire-proof phenolic board layer 6 not only plays a low-temperature heat insulation role, but also ensures the flatness of the partition wall surface; the first ceramic fiber layer 7 can block high-temperature heat and ensure that the temperature on the driver's cab side meets the fire protection standards; the outer frame 8 made of stainless steel can ensure the rigidity of the partition wall itself.
[0072] When the driver's cab is exposed to fire, the stainless steel second steel plate layer 9 ensures the partition's integrity, preventing it from burning through for a long time. The second fire-resistant phenolic plate layer 11 not only provides low-temperature insulation but also ensures the partition's surface flatness. The stainless steel inner frame 12 ensures the partition's rigidity. The first fire-resistant expansion strip 13 expands upon heat to seal the gap between the partition door and the door frame.
[0073] The rail vehicle driver's cab partition wall of the present application not only meets the conventional single-sided 30-minute structural fire protection, but also meets the thermal insulation and integrity requirements on both sides of the partition wall. Through double-sided fire protection, the fire protection function of the driver's cab partition wall is better improved, and the fire protection effect is improved. Moreover, both the inner and outer sides of the partition wall structure can meet different fire protection standards and achieve universality. For example, it can meet different fire protection structural requirements such as EN45545, BS6853, NFPA130, and AS7529.3. Compared with the existing technology, the present application does not need to spend a lot of manpower and material resources to redesign the partition wall structure and conduct repeated verification and testing during the partition wall design stage. Therefore, the design scheme of the present application greatly shortens the partition wall design cycle and reduces design costs due to its universality.
[0074] By comparison, it can be seen that the fire protection structure of the driver's cab partition wall in the existing technology only meets the fire protection requirements on one side, and the partition wall structures designed for different fire protection standards are different, which leads to a long design cycle and verification time and increases the design cost.
[0075] The partition structure of the present application is universal, can improve design efficiency, enhance the standardization and modularization of design, and meet the requirements of multiple fire protection standards.
[0076] Example 3
[0077] This embodiment provides a rail vehicle, including the rail vehicle driver's cab partition wall described in Example 2, which can achieve double-sided fire protection of the driver's cab partition wall, improve the fire protection effect, and meet multiple fire protection standards to achieve universality. Compared with the existing technology, during the partition wall design stage, there is no need to spend a lot of manpower and material resources to redesign the partition wall structure and conduct repeated verification and inspection. Therefore, the design scheme of this application greatly shortens the partition wall design cycle and reduces design costs due to its universality.
