Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation, and in particular to a fireproof glass cover for a track area. Background Art

[0002] With the booming development of modern rail transit, the rail transit area, a key area within the system, encompasses tracks, power supply facilities, communication lines, and numerous operational support equipment. As urban rail transit networks become increasingly dense, passenger volume and train frequency continue to rise, the security challenges facing rail transit areas are becoming increasingly complex and diverse, leading to the emergence of fire-resistant glass covers for rail transit areas.

[0003] Traditional rail transit construction focuses on stabilizing track structures, optimizing vehicle performance, and improving the accuracy of signal systems, but to a certain extent, it has neglected the critical aspect of fire prevention in track areas. In the early days, track areas mostly used ordinary glass or simple protective barriers, which are extremely fragile in the face of fire. Once a fire breaks out in buildings or facilities along the track, flames and high-temperature smoke can easily invade the track area, interfering with normal traffic signal transmission and causing communication lines to short-circuit and malfunction. The strong heat radiation may also directly burn track fasteners and power supply equipment, causing track deformation and power outages, instantly paralyzing the entire rail transit line. What's more, the flying fire and high-temperature debris generated by the fire may also break ordinary glass, causing its fragments to scatter, endangering the safety of passing trains and passengers and staff on board. The subsequent cleanup and repair work is also extremely tedious and complicated.

[0004] Furthermore, because rail transit often traverses relatively enclosed or semi-enclosed spaces like underground tunnels and elevated sections, air circulation is restricted. Heat cannot dissipate quickly when a fire breaks out, and the fire spreads at an unimaginable rate. Existing fire prevention methods, such as relying solely on fire sprinkler systems, are extremely limited in effectiveness. The large amount of water vapor not only affects the normal operation of electrical equipment but also fails to prevent the fire from spreading to key driving areas.

[0005] With the innovation of material science and fire protection technology, fireproof glass covers for track areas have come to the fore. It integrates advanced glass manufacturing technology with fire retardant technology, utilizes a multi-layer composite structure, and cleverly combines fireproof adhesives, thermal insulation materials, and high-strength glass substrates. On the one hand, this type of glass cover can, with its excellent fire resistance integrity, steadily block flames and smoke for up to several hours when a fire strikes, strictly observe the boundaries of the track area, and buy enough time for fire rescue; on the other hand, through a special insulation mechanism, it effectively reduces the efficiency of heat transfer, protects sensitive equipment inside the track area from high temperatures, and maintains normal signal conduction and stable power supply output. In addition, its stable material structure also gives it the ability to resist a certain impact force, and can cope with unexpected conditions such as train operation vibration and foreign object impact, protecting the safety of the track area in all directions, and meeting the stringent requirements for efficient and safe operation of rail transit;

[0006] High pressure will be generated during train operation vibration, foreign object impact, etc., and the lack of a buffer structure can easily lead to damage;

[0007] In the existing technology, the fireproof glass cover in the track area is simply made of a composite material of a substrate. The joints lack a high-pressure buffer structure, and the high-pressure buffer strength cannot be adjusted. The buffering is absorbed by the stiffness of the material in the initial stage, which easily leads to accelerated accumulation of high pressure inside the composite material, causing it to break. The composite material cannot change its buffering strength after being subjected to high pressure, which reduces the service life and safety of the composite material. Summary of the Invention

[0041] See also Figure 4 , Figure 4 This is a schematic diagram of the main cross-sectional structure of the installation steel box of the present invention.

[0042] The adjustable buffer mechanism is arranged on the top of the steel box 8 and is used for buffering the vibration of the composite glass connecting mechanism; the adjustable buffer mechanism comprises a pressing block 901, a pressure sensor 902, a damping adjusting plate 903, an adjusting rod 904 and a damping spring 905, the pressing block 901 is fixedly installed on the bottom of the buffer base plate 9, the pressure sensor 902 is arranged in four groups and is annularly and equidistantly inlaid on the top of the damping adjusting plate 903, the damping adjusting plate 903 is fixedly installed with the pressing block 901 through the pressure sensor 902, the adjusting rod 904 is screw-connected in the inside of the damping adjusting plate 903, the damping spring 905 is sleeved on the surface of the adjusting rod 904, a stop ring is fixedly installed on the bottom of the surface of the adjusting rod 904 and on the top of the inner wall of the steel box 8, the top end of the damping spring 905 is fixedly installed with the bottom of the damping adjusting plate 903, and the bottom end of the damping spring 905 is fixedly installed with the top of the steel box 8.

[0044] Please refer to Figure 6 , Figure 7 and Figure 8 , Figure 6 for the three-dimensional structure schematic view of the present application Figure 4 . Figure 7 for the local cut structure schematic view of the damping cylinder body of the present application Figure 8 for the explosion three-dimensional structure schematic view of the piston block of the present application.

[0045] The adjustable damping mechanism is arranged on both sides of the top of the inner wall of the thick fireproof frame 12, and is used to adjust the damping force to adapt to the adjustable buffer mechanism; the adjustable damping mechanism includes a damping cylinder 101, a connecting frame 102, a piston rod 103, a damping force adjustment rod 104, a piston block 105, a limiting ring frame 106, an adjusting ring 107, a limiting groove 1031 and an oil through hole 1051. The tops of the two groups of damping cylinders 101 are fixedly installed on both sides of the top of the inner wall of the thick fireproof frame 12 respectively, one end of the connecting frame 102 is fixedly installed on the buffer substrate 9, and the other end is fixedly installed on the piston rod 103, the piston block 105 is slidably installed inside the damping cylinder 101, and the piston rod 103 The top is fixedly installed with the piston block 105, the interior of the damping cylinder 101 is filled with hydraulic oil, the damping force adjusting rod 104 is rotatably installed inside the piston rod 103, and the top end passes through the piston block 105, and there are two groups of adjusting rings 107 which are symmetrically installed on the top and bottom of the piston block 105.

[0046] The connecting frame 102 is driven by the buffer base plate 9, and then the piston rod 103 can be driven to reciprocate up and down through the connecting frame 102. When the piston rod 103 drives the piston block 105 to move when the damping cylinder 101 is filled with hydraulic oil, the flow rate of the hydraulic oil determines the damping force. At this time, the adjustment hole 1071 on the adjustment ring 107 is staggered with the oil through hole 1051 to adjust the flow rate, thereby adjusting the damping force. The damping force is controlled by the torsion of the damping force adjustment rod 104. When the shock absorber spring 905 is rotated, the damping force is adjusted. When the rigidity is increased by squeezing, the adjusting ring 107 is twisted, so that the interlaced gap between the adjusting hole 1071 and the oil through hole 1051 is correspondingly reduced, thereby increasing the damping force, improving the damping efficiency, and matching the current shock-absorbing spring 905. When the shock-absorbing spring 905 is loosened upward by the shock-absorbing adjusting plate 903 and the rigidity is reduced, the adjusting ring 107 can be twisted to increase the interlaced gap between the adjusting hole 1071 and the oil through hole 1051, thereby reducing the damping force, and matching the current elastic force of the shock-absorbing spring 905.

Then, the driven rod 111 can be driven to rotate through the driven gear 118. After the driven rod 111 rotates, the switching component can have transmission force. When the switching component switches up and down to the corresponding meshing position with the large gear 9041 and the damping force adjustment gear 1041, it can drive the large gear 9041 and the damping force adjustment gear 1041. At the same time, the tensioning force adjustment component can ensure the driving stability of the toothed belt 119 to avoid loosening of the toothed belt 119 and causing unstable transmission of the driven gear 118.

[0051] The switching assembly includes a coupling tooth 112, a limit frame 113, an arc frame 114 and an electric push rod 115. The coupling tooth 112 is installed on the surface of the driven rod 111 through a slidable power coupling in a keyway and is located inside the limit frame 113. The limit frame 113 is slidably installed on the surface of the driven rod 111. The electric push rod 115 is fixedly installed on the rear side of the bottom of the stabilizing frame 116. The output end of the electric push rod 115 is fixedly installed on the arc frame 114, and the two ends of the arc frame 114 are fixedly installed on the two sets of limit frames 113.

[0052] The electric push rod 115 can drive the arc frame 114 to move up and down through the output end. When the arc frame 114 moves upward, it drives the limit frame 113 to move upward. The limit frame 113 drives the coupling tooth 112 to move upward and engage with the large gear 9041, thereby driving the adjustment rod 904 to rotate. After the adjustment rod 904 rotates, the shock-absorbing adjustment plate 903 can be moved downward under the reaction force of the retaining ring, so that the shock-absorbing spring 905 is compressed, thereby increasing the initial rigidity of the shock-absorbing spring 905. Reversal causes the shock-absorbing adjustment plate 903 to move upward under the thread twisting of the adjustment rod 904, reducing the initial rigidity of the shock-absorbing spring 905, thereby facilitating the absorption of vibrations of different intensities.

[0054] The driving assembly includes a motor 117, a driving gear 1171 and a driving rod 1172. The motor 117 is fixedly mounted on the rear side of the top of the stabilizing frame 116. The output end of the motor 117 is fixedly mounted with a driving rod 1172. The bottom of the driving rod 1172 passes through the stabilizing frame 116 and extends to the bottom of the inner wall of the mounting steel box 8 to rotate with the mounting steel box 8. The driving gear 1171 is mounted on the driving rod 1172 through a slidable power coupling in a keyway and is located at the inner center of the stabilizing frame 116. The driving gear 1171 is engaged with the toothed belt 119. The driving gear 1171 is connected to the two sets of driven gears 118 through the toothed belt 119. When the motor 117 is started, the driving rod 1172 is driven to rotate, and then the rotation of the driving rod 1172 drives the driving gear 1171 to rotate, and the engagement of the driving gear 1171 with the toothed belt 119 drives the two sets of driven gears 118 to rotate.

The trapezoidal slider 1163 is threadedly connected to the surface of the adjusting bolt 1162, and the trapezoidal slider 1163 slides with the bottom of the stabilizing frame 116. The blocking rod 1164 is fixedly mounted on the bottom of the trapezoidal slider 1163 and cooperates with the toothed belt 119; the torsion adjusting bolt 1162 can not move axially under the rotation limit of the mounting plate 1161 and the retaining spring, and after self-rotation, it drives the trapezoidal slider 1163 threadedly connected to it to move in the front and rear directions, and then the trapezoidal slider 1163 drives the blocking rod 1164 to squeeze and tension the toothed belt 119, thereby ensuring the stability of the engagement between the toothed belt 119 and the driven gear 118 when the toothed belt 119 rotates.

[0058] Working Principle: In actual rail transit operation, sudden events such as train vibrations and collisions with foreign objects can instantly generate high-voltage shocks at the fire-resistant glass cover in the track area. At this point, the borosilicate fire-resistant laminated glass 97, located in a key protective position, bears the brunt of the high-pressure force. Part of this high-pressure-induced vibration is transmitted through the thick aluminum veneer 93, while the remaining portion is quickly and accurately transmitted to the buffer base plate 9 via the stable connection structure formed by the fire-resistant rubber strip 92 and the steel adapter 91.

[0059] The limit plates 9001 on either side of the bottom of the buffer baseplate 9 then work closely with the limiter matching frames 9002 on either side of the top of the mounting steel box 8 to perform their limiting function, ensuring that the buffer baseplate 9 can only slide stably in the predetermined direction under high-pressure impact, effectively preventing structural damage caused by uneven force or uncontrolled displacement, and laying the foundation for subsequent buffering action. At the same time, the buffer baseplate 9 simultaneously transmits the impact force to the connecting frame 102 and the pressure block 901, which precisely contacts the shock-absorbing adjustment plate 903.

[0060] The four groups of pressure sensors 902 equidistantly embedded in a circular shape on the top of the shock-absorbing adjustment plate 903 are activated in real time, sensitively capturing the current pressure value and immediately transmitting the data to the external controller. The external controller quickly compares and analyzes the current pressure data based on the preset buffering force threshold range: if the pressure is within the normal range where the buffering force does not need to be adjusted, the shock-absorbing adjustment plate 903 will directly relay the pressure to the shock-absorbing spring 905. The shock-absorbing spring 905, with its excellent elastic deformation characteristics, steadily absorbs and dissipates the impact force, and cooperates with the adjustable damping mechanism to effectively suppress repeated shocks caused by impact, prevent the high borosilicate fireproof laminated glass 97 from suffering from excessive pressure accumulation in a short period of time, achieve the effect of gradually dispersing and buffering high-pressure impacts, and effectively ensure the stability of the glass structure;

[0061] When the external controller determines that the pressure data exceeds the normal threshold and the buffer force needs to be adjusted urgently, the entire adjustment process is quickly and orderly initiated. The system first precisely activates the motor 117 on the top and rear side of the stabilizing frame 116. The output end of the motor 117 drives the drive rod 1172 rigidly connected to it to rotate at high speed. The drive rod 1172 then drives the drive gear 1171, which is mounted on a keyway and has a slidable power coupling, to rotate synchronously. The drive gear 1171, through its precise meshing relationship with the toothed belt 119, steadily drives the two sets of driven gears 118 to rotate smoothly, transmitting stable power for subsequent critical adjustment actions.

[0062] Next, electric push rod 115 is manipulated specifically based on the desired adjustment—the stiffness adjustment of damping spring 905 or the adaptive change in the damping force of piston block 105. If the initial stiffness of damping spring 905 needs to be strengthened to withstand high pressure, electric push rod 115 is driven upward, pushing arc frame 114 upward synchronously. Arc frame 114, thanks to its secure connection to limit frame 113, pulls limit frame 113, driving coupling gear 112 precisely upward, allowing it to mesh tightly with large gear 9041. Large gear 9041 rotates under force, and with the aid of the threaded adjustment rod 904 and the reaction force of the retaining ring, it steadily pushes damping adjustment plate 903 downward, effectively compressing damping spring 905 and, as expected, increasing its initial stiffness to better adapt to high-pressure impacts. On the contrary, when the electric push rod 115 is driven downward, the various components are linked in reverse, the shock-absorbing adjustment plate 903 moves upward, and the initial rigidity of the shock-absorbing spring 905 is reduced, which is conducive to gently absorbing smaller impact forces and reducing unnecessary mechanical wear of the glass under low-pressure conditions;

[0063] When precise damping force adjustment is required, the electric push rod 115 is driven downward, driving the arc frame 114, the limit frame 113, and the coupling gear 112 in a sequential manner until the coupling gear 112 precisely engages the damping force adjustment gear 1041. At this point, the coupling gear 112 drives the damping force adjustment gear 1041 to rotate smoothly, thereby driving the damping force adjustment rod 104 to rotate synchronously. The damping force adjustment rod 104, thanks to its rigid connection with the adjustment ring 107, cleverly twists the adjustment ring 107. The eight carefully designed groups of adjustment holes 1071 on the adjustment ring 107 intersect with the eight groups of oil holes 1051 within the piston block 105. By precisely controlling the interlaced gap between the two, the flow rate of the hydraulic oil in the damping cylinder 101 is cleverly adjusted, achieving precise adjustment of the damping force on demand. When the rigidity of the shock absorber spring 905 increases due to high-pressure extrusion, the interleaving gap is appropriately reduced, the damping force is increased, and the strong elastic force of the shock absorber spring 905 is efficiently matched to synergistically suppress vibration; when the rigidity of the shock absorber spring 905 decreases due to adjustment, the interleaving gap is correspondingly increased and the damping force is appropriately reduced to ensure that it complements the current elastic force of the shock absorber spring 905, maintaining a delicate balance between the buffering and damping systems in all directions.

[0064] After undergoing the above-mentioned intelligent and precise adjustment process of elastic force and damping force, even if the high borosilicate fire-resistant laminated glass 97 is subjected to high-pressure impact, it can still rely on this set of sophisticated and coordinated buffering and damping adjustment mechanisms to adaptively disperse and eliminate the impact force, significantly improving its own safety in use, effectively extending its service life, and building a solid barrier for the stable operation of rail area facilities and the safety of personnel.
