Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit platform safety protection equipment, and particularly relates to a high-speed rail platform safety protection device suitable for multiple vehicle types. BACKGROUND

[0002] The high-speed rail platform is an important hub area for passengers to get on and off the train, and its safety protection work is of great significance. If the passengers are too close to the train when it enters the station during high-speed operation, serious accidents such as collision and being dragged into the train may occur, which endangers the safety of life and health of the passengers and also causes great interference and damage to the normal operation order of the high-speed rail. In the past, the high-speed rail platform mainly relied on the verbal prompting of platform staff to guide passengers to wait outside the safety yellow line. This traditional manual prompting method has obvious limitations and cannot ensure that every passenger will consciously comply with safety regulations. In particular, children who lack supervision are often curious and lively, and are easy to cross the safety yellow line inadvertently, thereby bringing great risks to their personal safety. At present, there are various types of platform safety protection facilities, but they all have different degrees of defects.

[0003] Firstly, the high-speed rail platform telescopic safety fence sets left and right movable piles, a turnover footboard and a T-shaped fixed rack, etc. This fence not only occupies a lot of platform space, affecting the normal use of the platform and the passage of passengers, but also the whole device is relatively heavy and lacks flexibility, and it is difficult to quickly and flexibly adjust and handle in case of an emergency, so it cannot effectively play a safety protection role.

[0004] Secondly, the technical scheme of the full-height platform door adopts a full-closed structure full-height platform door to completely separate the track area from the platform area. Although it has a significant effect on ensuring the safety of passengers waiting for the train and can effectively prevent passengers from accidentally entering the track area. However, the construction cost of the full-height platform door is high, and a large amount of funds needs to be invested in the purchase, installation and commissioning of equipment. Moreover, the maintenance cost is also relatively high in the subsequent use process, including daily maintenance of equipment, replacement of parts, etc., which undoubtedly increases the overall cost of high-speed rail operation.

[0005] In addition, the technical scheme of the rope belt protection facility uses rope belts instead of large-area special glass and supporting door frames and other steel facilities, which saves the construction cost to a certain extent. However, this rope belt protection facility has obvious safety loopholes. Since there is a large gap between the rope belts and the platform ground, there is still a risk of falling into the track area for children and small luggage, and it cannot provide all-around and dead-angle-free safety protection for passengers.

[0006] Moreover, the technical scheme of the semi-high platform door similar to the subway ground station is adopted, and the platform door can only be suitable for one or several vehicle types with close door opening positions. However, the high-speed rail vehicles in China have many types, and the door spacing of different types of vehicles is different. Therefore, the single-specification platform door cannot meet the needs of the high-speed rail platform door, and in the actual use process, the opening position and opening degree of the platform door do not match the stopping position of the high-speed rail of different vehicle types, thereby affecting the normal use and safety protection effect of the platform door.

[0007] Therefore, there is an urgent need for a high-speed rail platform safety protection device which can save space, flexibly handle emergencies, reduce cost, eliminate gap hidden dangers, and adapt to multiple vehicle types. SUMMARY

[0008] The embodiment of the present application provides a high-speed rail platform safety protection device adapted to multiple vehicle types to solve the technical problems in the prior art that the high-speed rail platform protection device cannot consider multiple vehicle type adaptation, safety protection gap, cost and space occupation, and provides a high-speed rail platform safety protection device which can save space, flexibly handle emergencies, reduce cost, eliminate gap hidden dangers and adapt to multiple vehicle types.

[0009] In view of the above technical problems, the embodiment of the present application provides a high-speed rail platform safety protection device adapted to multiple vehicle types, comprising a plurality of lifting units, a plurality of fixing members slidingly installed on the lifting units, and a traction rope connecting the fixing members on adjacent lifting units; the lifting unit is composed of a first lifting mechanism and a second lifting mechanism arranged in mirror symmetry, and the first lifting mechanism and the second lifting mechanism are structurally identical; the first lifting mechanism comprises a fixed base, a lifting drive assembly installed on the fixed base, and a lifting rail connected to the lifting drive assembly;

[0010] A plurality of fixing members are slidingly installed on the lifting rail through a synchronous drive assembly;

[0011] Among them, a plurality of lifting units are arranged in a horizontal array along the edge of the platform, two lifting units form a group, and each group of lifting units is synchronously lifted to adapt to the stopping position of the doors of different vehicle types.

[0012] Optionally, the lifting drive assembly comprises a driving motor fixedly installed on the fixed base, a push rod installed on the fixed base and connected to the output shaft of the driving motor, a hinged seat installed on the inner side wall of the lifting rail, a fixed track slidingly connected to the outer side wall of the lifting rail, and a sliding bar installed on the lifting rail;

[0013] One end of the push rod is connected to the output shaft of the driving motor, and the other end is connected to the hinged seat.

[0014] Optionally, the outer wall of the lifting railing is also provided with multiple sets of rollers, which can slide along the fixed track under the push of the push rod; the multiple sets of rollers and the fixed track form an anti-lateral pull assembly;

[0015] The roller is embedded in the fixed track and rolls in contact with the fixed track to constrain the lateral displacement of the lifting railing and counteract the lateral tension.

[0016] Optionally, the fixed base is provided with a guide frame and a limiting frame for the push rod to pass through.

[0017] Optionally, the synchronous drive assembly includes a first synchronous wheel fixedly installed at the top of the frame of the lifting railing, a second synchronous wheel fixedly installed at the bottom of the frame of the lifting railing, and a synchronous belt wound between the first synchronous wheel and the second synchronous wheel; a section of the synchronous belt near the limiting frame passes through the limiting frame and is fixedly connected to the limiting frame.

[0018] Optionally, a guide rail is also provided on the outer wall of the lifting railing, and each of the plurality of fixing members is respectively connected to a slider; the number of fixing members is set to 5, and in the longitudinal direction of the lifting railing, the 5 sliders from the top to the bottom of the lifting railing are sequentially the first slider, the second slider, the third slider, the fourth slider and the fifth slider. The first slider is fixedly installed on the guide rail, and the fifth slider is fixedly connected to the section of the synchronous belt away from the limiting frame; adjacent sliders are connected by rubber elastic ropes.

[0019] Optionally, the multi-model-compatible high-speed rail platform safety protection device also includes a mounting frame, in which the first and second lifting mechanisms of the lifting unit are mirror-symmetrically mounted.

[0020] Optionally, the mounting frame includes, but is not limited to, a triangular frame, a pentagonal frame, or a trapezoidal frame. A display screen for displaying the carriage number is provided on two sides of the triangular frame, and a display screen for displaying the carriage number is provided on three sides or two symmetrical sides of the pentagonal frame; a display screen for displaying the carriage number is provided on three sides or two symmetrical inclined surfaces of the trapezoidal frame.

[0021] This invention achieves comprehensive efficiency improvements through innovative design: it adopts a mirrored layout of dual lifting mechanisms and a grouped synchronous control scheme, driving the sliders and multiple sets of lifting barriers to rise and fall synchronously. This allows for precise adaptation to the door positions of different vehicle models, significantly improving platform compatibility and completely solving the adaptation problem caused by differences in door positions across multiple vehicle models. The roller-track anti-side-pull assembly and guide limiting structure ensure smooth and non-lateral lifting. Simultaneously, a synchronous belt drives multi-stage slider linkage, forming a flexible protective rope barrier with a dense lower section to prevent crawling and climbing, and a loose upper section that does not obstruct the view. This eliminates the gap hazards of traditional facilities and saves platform space. Using an electric push rod as the power source, the entire solution is modular, facilitating installation and maintenance while also reducing costs.

[0022] The invention features a compact and stable horizontal array of multiple lifting units. Its five-segment protective rope structure provides stepless protection from 110mm to 1400mm. The lower netting structure effectively prevents children from running and jumping, and objects from falling. The upper, loosely designed structure ensures safety while maintaining unobstructed visibility. The entire protective system occupies zero platform space. In terms of safety, the device physically isolates passengers and objects from entering the tracks, preventing safety hazards such as emergency braking and ensuring punctuality. At the platform management level, the integrated guidance screen's safety service platform dynamically displays train numbers, times, and carriage information. Combined with the intelligent opening and closing of automated guardrails, it effectively guides passenger flow, reduces crowding, and significantly improves platform operational efficiency and service quality, providing a safe, intelligent, and efficient comprehensive solution for high-speed rail platforms.

Detailed Implementation

[0033] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0034] In the description of this invention, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] like Figures 1 to 2 As shown, one embodiment of the present invention provides a high-speed rail platform safety protection device adaptable to multiple train models, including multiple lifting units 1, multiple fixing parts 2 slidably mounted on the lifting units 1, and traction ropes 3 connecting the fixing parts 2 on adjacent lifting units 1; each lifting unit 1 consists of a first lifting mechanism 11 and a second lifting mechanism 12 arranged in a mirror-symmetrical manner, the first lifting mechanism 11 and the second lifting mechanism 12 having the same structure; the first lifting mechanism 11 includes a fixed base 111, a lifting drive assembly 112 mounted on the fixed base 111, and a lifting railing 113 connected to the lifting drive assembly 112. The multiple fixing parts 2 are slidably mounted on the lifting railing 113 via a synchronous drive assembly 4.

[0037] The lifting units 1 are arranged in a horizontal array along the edge of the platform, with two lifting units 1 forming a group. Each group of lifting units 1 lifts and lowers synchronously to accommodate the parking positions of doors on different vehicle models. Each lifting unit 1 consists of a first lifting mechanism 11 and a second lifting mechanism 12 with identical structures. The fixing members 2 on the first lifting mechanism 11 of the same group of lifting units 1 are connected to each other by a traction rope 3.

[0038] Understandably, the multi-model-compatible high-speed rail platform safety protection device consists of multiple spaced-apart lifting units 1. These units can be grouped into sets of two and placed before the high-speed rail doors, as needed. Thus, by horizontally arraying multiple lifting units 1 along the platform edge and controlling their synchronous lifting in pairs, the device can flexibly adapt to the door positions of different high-speed rail models, achieving precise matching of the protected area. Each unit group consists of a mirror-symmetrical double lifting mechanism, working in conjunction with a linkage rope barrier formed by a fixing component 2 and a traction rope 3. This effectively prevents passengers from falling onto the platform or items from entering the platform tracks through physical isolation, enhancing overall structural stability. Furthermore, the density of the rope barrier can be adjusted via the synchronous drive component 4, forming a continuous protective barrier that is dense at the bottom to prevent crawling and climbing, and loose at the top to avoid obstructing the view. This effectively eliminates potential safety gaps while ensuring the reliability and flexibility of platform safety protection, while accommodating multiple train models and improving space utilization.

[0039] In an implementation, such as Figure 1 and Figure 3As shown, the lifting drive assembly 112 includes a drive motor 1121 fixedly mounted on the fixed base 111, a push rod 1122 mounted on the fixed base 111 and connected to the output shaft of the drive motor 1121, a hinge seat 1123 mounted on the inner side wall of the lifting railing 113, a fixed track 1124 slidably connected to the outer side wall of the lifting railing 113, and a sliding bar 1125 mounted on the lifting railing 113. One end of the push rod 1122 is connected to the output shaft of the drive motor 1121, and the other end is connected to the hinge seat 1123.

[0040] Understandably, when the drive motor 1121 is started, the push rod 1122 rotates around the hinge seat 1123. Since the hinge seat 1123 is fixedly installed on the inner wall of the lifting railing 113, the rotation of the push rod 1122 can simultaneously push the lifting railing 113, which is fixedly connected to the hinge seat 1123, to move up and down in a direction perpendicular to the ground. During the lifting movement, the lifting railing 113 slides synchronously within the fixed track 1124. The sliding bar 1125 installed on the lifting railing 113 also slides synchronously along with other components within the device. The lifting drive assembly 112 drives the push rod 1122 to rotate around the hinge seat 1123 via the drive motor 1121, converting rotational power into vertical linear motion of the lifting railing 113.

[0041] In an implementation, such as Figure 1 and Figure 3 As shown, multiple sets of rollers 5 are also provided on the outer wall of the lifting railing 113. These rollers 5 can slide along the fixed track 1124 under the push of the push rod 1122. The multiple sets of rollers 5 and the fixed track 1124 form an anti-lateral pull assembly. Specifically, the rollers 5 are embedded in the fixed track 1124 and roll in contact with it, thereby constraining the lateral displacement of the lifting railing 113 and counteracting lateral tension.

[0042] Understandably, this anti-lateral pull assembly forms a rolling contact engagement by embedding multiple sets of rollers 5 into the fixed track 1124. During the vertical lifting and lowering of the lifting railing 113, it simultaneously constrains its lateral displacement and counteracts external tension. By replacing sliding friction with rolling friction, it effectively enhances the system's resistance to lateral disturbances, prevents the railing from swaying or derailing, and ensures smooth and stable longitudinal lifting and lowering movements. This significantly improves the operational stability and durability of the protective device under dynamic stress environments.

[0043] In an implementation, such as Figure 1As shown, the fixed base 111 is provided with a guide frame 6 and a limiting frame 7 for the push rod 1122 to pass through. Understandably, the guide frame 6 provides an installation channel for the push rod 1122. The limiting frame 7 provides an installation position for the subsequent synchronous belt. The guide frame 6 ensures stable extension and retraction of the push rod 1122 in the vertical direction, while the limiting frame 7 supports the synchronous drive assembly 4 and provides a connection base point for the fixing member 2. Together, they achieve structural integration of lifting drive force and rope adjustment function.

[0044] In an implementation, such as Figure 1 and Figure 3 As shown, the synchronous drive assembly 4 includes a first synchronous wheel 41 fixedly installed at the top of the frame of the lifting railing 113, a second synchronous wheel 42 fixedly installed at the bottom of the frame of the lifting railing 113, and a synchronous belt 43 wound between the first synchronous wheel 41 and the second synchronous wheel 42; a section of the synchronous belt 43 near the limiting frame 7 passes through the limiting frame 7 and is fixedly connected to the limiting frame 7.

[0045] Understandably, when the lifting barrier 113 is raised, the first synchronous pulley 41 and the second synchronous pulley 42 rise with it. Since the limiting frame 7 and the guide frame 6 are fixed, the section of the synchronous belt 43 near the limiting frame 7 is fixedly connected to it. During the raising of the lifting barrier 113, relative rotation occurs between the synchronous belt 43 and the second synchronous pulley 42, driving the synchronous belt 43 to rotate. Figure 1 Rotating counterclockwise, that is, Figure 1 The left synchronous belt 43 descends, while the right synchronous belt 43 ascends. As the right synchronous belt 43 ascends, it can drive the five fixing parts 2 to ascend and eventually gather together.

[0046] As the lifting barrier 113 moves downward, the first synchronous pulley 41 and the second synchronous pulley 42 descend with it. Since the limiting frame 7 remains stationary, the section of the synchronous belt 43 near the limiting frame 7 remains fixedly connected. During the descent of the lifting barrier 113, relative rotation occurs between the synchronous belt 43 and the descending second synchronous pulley 42, driving the synchronous belt 43 to rotate clockwise. Figure 1 The left synchronous belt 43 rises while the right synchronous belt 43 falls. The falling of the right synchronous belt 43 causes the fifth slider, which is fixedly connected to it, to fall. At this time, the second to fourth sliders automatically slide down and unfold along the guide rail 8 under the action of gravity and the tension of the rubber elastic rope, so that the five fixing parts 2 are distributed at intervals on the lifting rail 113 (at this time, the fixing parts 2 can be fixed in position by existing technologies such as buckles), forming a protective rope rail structure that is dense at the bottom and loose at the top.

[0047] In an implementation, such as Figure 1 and Figure 4 As shown, a guide rail 8 is also provided on the outer wall of the lifting railing 113, and each of the multiple fixing parts 2 is respectively connected to a slider 9; the number of fixing parts 2 is set to 5. Along the longitudinal direction of the lifting railing 113, the 5 sliders 9, from the top to the bottom of the lifting railing 113, are sequentially designated as the first slider, second slider, third slider, fourth slider, and fifth slider. The first slider is fixedly installed on the guide rail 8 (the first slider is the topmost slider, and its relative position is always fixed; its fixing method can be achieved through guide rail limiting blocks, i.e., one guide rail limiting block is installed above and below the first slider to limit its relative position). The fifth slider is fixedly connected to the section of the synchronous belt 43 away from the limiting frame 7; adjacent sliders 9 are connected by rubber elastic ropes (not shown). It is understood that the number of fixing parts 2 can be set according to requirements and is not limited to 5. The number of fixing parts can be adjusted according to actual needs to adapt to different protection height requirements. Since the first slider, which is in the first position, is fixedly installed on the guide rail 8, and the fifth slider, which is in the fifth position, is fixedly connected to the synchronous belt 43 on the right, when the synchronous belt 43 on the right descends, the fifth slider descends, and at this time the second to fourth sliders automatically slide down along the guide rail 8 under the action of gravity.

[0048] In an implementation, such as Figure 2 As shown, the multi-model adaptable high-speed rail platform safety protection device also includes a mounting frame 10. The first lifting mechanism 11 and the second lifting mechanism 12 of the lifting unit 1 are mirror-symmetrically installed within the mounting frame 10. Understandably, the mounting frame includes, but is not limited to, triangular, pentagonal, and trapezoidal frames. The mounting frame 10 adopts a polygonal structure such as a triangular, pentagonal, or trapezoidal shape, utilizing geometric and mechanical properties to disperse stress, enhance anti-overturning ability and wind pressure resistance. Simultaneously, the inclined surface design optimizes visual guidance and space utilization, achieving both structural compactness and integrated protective function, while also improving the stability and installation adaptability of the device in the high-speed operating environment of high-speed rail.

[0049] In addition, such as Figure 5 As shown, displays for showing the carriage number are provided on two sides of the triangular frame. Figure 6 As shown, displays for showing carriage numbers are provided on three faces or two symmetrical faces of the pentagonal frame. Figure 7As shown, displays for showing carriage numbers are installed on three sides or two symmetrical inclined surfaces of the trapezoidal frame. This forms a multi-faceted three-dimensional display structure, breaking through the limitations of the single-plane display in existing safety systems. Passengers can clearly identify carriage number information from different angles and distances without having to approach the carriage, effectively improving the visibility and recognizability of the carriage location. This three-dimensional display solution allows passengers to locate their target carriage in advance, reducing crowding and congestion at platform junctions, lowering the workload of staff, and significantly improving passenger flow efficiency and travel experience.

[0050] Furthermore, the triangle, as the most stable geometric shape, possesses a three-point force balance characteristic that allows the safety protection device on the high-speed railway platform to maintain rigidity under the impact of airflow and vehicle vibration generated by the high-speed operation of the train, avoiding structural deformation caused by resonance. The isosceles triangular support structure formed by its base and the ground can distribute the vertical load to the two side columns, improving the anti-overturning moment compared to a rectangular structure, making it particularly suitable for dynamic docking scenarios between the platform and the train. The triangular layout reduces the lateral space occupied by the device at the platform edge, reserving a wider passage for passengers. At the same time, the sloping design naturally guides the eye to focus on the screen area, forming a visual flow that conforms to the 15° golden angle of vision in ergonomics.

[0051] The pentagonal body, through the angular distribution of its adjacent sides, disperses the vertical gravitational load and the horizontal airflow impact force from the train onto five stress surfaces. This reduces the stress concentration factor compared to a triangular structure, extending the metal's fatigue life under long-term dynamic loads. The five-legged support layout at the bottom increases the contact area with the ground, thereby improving the static stability coefficient.

[0052] The trapezoidal body adopts a 1:1.5 size gradient design on the upper and lower bases, and forms a pyramid-like support structure with a 45° inclined side. Its overturning moment is improved compared with a cuboid of the same volume. The bottom adopts an enlarged base and is fixed with an expansion bolt system, which can adapt to various platform surfaces such as concrete and asphalt.

[0053] The working process of the multi-vehicle-adaptive high-speed rail platform safety protection device of the present invention is as follows:

[0054] Multiple lifting units 1 are arranged in a horizontal array along the edge of the platform, with each pair of lifting units 1 forming a group, and each group can be controlled independently.

[0055] Before the train enters the station, the drive motor 1121 starts, driving the lifting barrier 113 of the lifting unit 1 to descend vertically. The rollers 5 slide along the fixed track 1124 to prevent lateral deviation, and the lifting barrier 113 gradually retracts into the mounting frame 10. During the descent of the lifting barrier 113, relative rotation occurs between the synchronous belt 43 and the descending second synchronous pulley 42, driving the synchronous belt 43 to rotate clockwise.Figure 1 The left synchronous belt 43 rises while the right synchronous belt 43 falls. The falling of the right synchronous belt 43 causes the fifth slider, which is fixedly connected to it, to fall. At this time, the second to fourth sliders automatically slide down and unfold along the guide rail 8 under the action of gravity and the tension of the rubber elastic rope. Finally, the five fixing parts 2 are distributed at intervals on the lifting rail 113 (at this time, the fixing parts 2 can be fixed in position by existing technologies such as buckles), forming a protective rope rail structure that is dense at the bottom and loose at the top, which constitutes a protective barrier to isolate the track from the platform and prevent passengers from falling accidentally.

[0056] After the train comes to a complete stop at the station, the drive motor 1121 drives the lifting barrier 113 to rise. The first synchronous pulley 41 and the second synchronous pulley 42 rise along with the lifting barrier 113. Since the limiting frame 7 and the guide frame 6 are fixed, the section of the synchronous belt 43 near the limiting frame 7 is fixedly connected to it. During the lifting process of the lifting barrier 113, relative rotation occurs between the synchronous belt 43 and the rising second synchronous pulley 42 of the lifting barrier 113, driving the synchronous belt 43 to... Figure 1 Rotating counterclockwise, that is, Figure 1 The left synchronous belt 43 descends, while the right synchronous belt 43 ascends. As the right synchronous belt 43 ascends, it can simultaneously drive the fifth, fourth, third, and second sliders to ascend until the second slider contacts the first slider, and so on, until all the sliders finally come together, thus forming an aisle at the door.
