Description

Technical Field

[0001] This utility model relates to the field of transportation-related technology, and more specifically, to a safety enclosure device for urban rail transit. Background Technology

[0002] The daily operational safety of urban rail transit (such as subways and light rail) relies heavily on well-maintained protective facilities. These facilities help isolate the track area from non-operational areas, reducing the chances of unauthorized personnel accidentally entering the tracks or climbing over platform railings, thereby lowering safety risks.

[0003] Currently, commonly used enclosure devices in the industry mainly include fixed railings, mesh structures, and enclosed barriers. If the gaps between some fixed railings are too large, there may be a risk of people climbing them; if the gaps are too small, it may affect the ventilation and visibility of the area. Some mesh structures may not be strong enough, and their structural nodes may still provide opportunities for people to step on or grab onto them. Some enclosed barriers have relatively high costs, and in emergency scenarios, they may cause some inconvenience to on-site observation, operation, and response efficiency.

[0004] In view of this, this paper studies and improves upon existing problems, and provides a safety enclosure device for urban rail transit. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a safety enclosure device for urban rail transit, in order to solve the problems mentioned in the background art. The existing enclosure devices commonly used in the industry mainly include fixed railings, mesh structures and enclosed barriers: if the gaps of some fixed railings are set too large, there may be a risk of being climbed; if the gaps are designed too small, it may have a certain impact on the ventilation effect and visibility of the area; some mesh structures may have insufficient strength, and their own structural nodes may still provide certain conditions for people to step on or grab; some enclosed barriers have relatively high investment costs, and in emergency scenarios, they may bring certain inconveniences to on-site observation, operation and response efficiency.

[0006] To achieve the above objectives, this utility model provides a safety enclosure device for urban rail transit, which is accomplished by the following specific technical means:

[0007] A safety enclosure device for urban rail transit includes: a frame, threaded holes, columns, cavities, ball bearings, a top cover, reflective stickers, protrusions, plates, holes, and bolts; the frame has multiple threaded holes equidistantly arranged, each threaded hole being threadedly connected to a column; each column has multiple cavities equidistantly arranged, each cavity being movably connected to a ball bearing, the ball bearings being adapted to corresponding cavities; the frame is fixedly connected to a top cover by bolts; the top cover is fixedly connected to a protrusion, the protrusion being arc-shaped; and reflective stickers are fixedly connected to both the frame and the top cover.

[0008] As a further optimization of this technical solution, the tops of multiple columns in the urban rail transit safety enclosure device of this utility model are in contact with the bottom of the top cover.

[0009] As a further optimization of this technical solution, the frame of the urban rail transit safety enclosure device of this utility model is fixedly connected to a plate at one end and the other end, and the two plates are provided with multiple holes at equal intervals.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0011] 1. The design of this utility model, with its frame, threaded holes, cavities, columns, and ball bearings, utilizes multiple threaded holes in the frame to connect with corresponding columns to form a protective fence. Multiple columns are placed vertically and have multiple cavities, each containing a ball bearing. This structure not only achieves a combination of stability and ease of installation and disassembly through threaded connections, but also restricts personnel from climbing by allowing the ball bearings to rotate within the cavities. When personnel come into contact with the ball bearings, the bearings easily rotate with the applied force and cannot provide stable support. This avoids the shortcomings of existing devices without affecting ventilation, visibility, or emergency observation, thus helping to solve practical safety protection problems.

[0012] 2. The design of this utility model, with its frame, top cover, reflective pads, protrusions, and bolts, utilizes bolts to fix the top cover to the top of the frame, creating an upward constraint on the columns within the frame. This prevents displacement or detachment of the columns from the frame during long-term use, such as under external forces like upward lifting or vibration, further ensuring the overall stability of the enclosure structure. The bolt connection also facilitates the disassembly and assembly of the top cover during subsequent maintenance, allowing for easy inspection, adjustment, or replacement of the columns. The top of the top cover features an arc-shaped protrusion to prevent stress during climbing. Both the frame and top cover are equipped with reflective pads, which enhance the visual visibility of the device in low-light environments such as at night or at tunnel entrances. This helps passing personnel and vehicles quickly identify the boundaries of the enclosure, reducing the risk of collisions due to poor visibility. Furthermore, the reflective pads require no additional energy consumption, further enhancing the safety warning effect. Attached Figure Description

[0021] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0022] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1 to 4This utility model provides a specific technical implementation scheme for a safety enclosure device for urban rail transit:

[0024] A safety enclosure device for urban rail transit includes: a frame 1, threaded holes 2, columns 3, cavities 4, ball bearings 5, a top cover 6, reflective pads 7, protrusions 8, plates 9, holes 10, and bolts 11. The frame 1 has multiple threaded holes 2 equidistantly spaced, each threadedly connected to a column 3. This threaded connection provides strong pull-out resistance and lateral load-bearing capacity, resisting impacts from personnel climbing or external collisions on the column 3. It also allows for individual disassembly and assembly of the column 3, enabling targeted replacement if the column 3 is damaged without disassembling the entire frame 1. Multiple cavities 4 are equidistantly spaced within the columns 3, and each cavity 4 is movable. The device is equipped with ball bearings 5, which are adapted to the corresponding cavities 4. The inner wall of the cavity 4 is designed with a smooth arc surface, which not only provides space for the ball bearings 5 ​​to rotate flexibly, but also prevents the ball bearings 5 ​​from falling out of the cavity by designing the size of the cavity 4 opening smaller than the diameter of the ball bearings 5. When a person attempts to climb, the ball bearings 5 ​​will rotate synchronously with the direction of the applied force when the hand or foot comes into contact with them, and cannot provide stable support, thus structurally blocking the climbing path. At the same time, the gap between the columns 3 is designed to match the ball bearings 5, so as not to block the ventilation channel or affect the field of vision in emergency situations, thus avoiding the problem of limited field of vision of traditional enclosure devices.

[0025] The frame 1 is fixedly connected to the top cover 6 by bolts 11. When it is necessary to inspect or replace the column 3, the top cover 6 can be removed simply by unscrewing the bolts 11 without damaging the frame 1 or the column 3, thus improving the convenience of maintenance. The top cover 6 is fixedly connected to a protrusion 8. The protrusion 8 is arc-shaped, and the arc-shaped surface has no sharp edges or flat stress points, so personnel cannot use the protrusion 8 to grab or step on it, thus structurally eliminating the possibility of climbing by using the protrusion 8.

[0026] Both the frame 1 and the top cover 6 are fixedly connected with reflective stickers 7. The reflective stickers 7 are mainly designed for low-light scenarios such as nighttime, tunnel entrances and exits, and underground stations. When light shines on the reflective stickers 7, it will reflect to form a clear light signal, clearly outlining the boundary of the protective device. This helps pedestrians and rail vehicles to quickly identify the protected area and avoid accidental collisions due to poor visibility. Moreover, the reflective stickers 7 do not need to be connected to an external power source. They rely solely on passive reflection to achieve the warning function, which saves on circuit laying and energy consumption costs and avoids warning failure caused by electrical component failure, thus balancing safety warning effect and economic efficiency.

[0027] The tops of multiple columns 3 are in contact with the bottom of the top cover 6. The core function of the top cover 6 is to form an upward limiting constraint on the columns 3 inside the frame 1, so as to prevent the columns 3 from shifting or detaching from the frame 1 when subjected to external forces such as the upward force when people climb or strong wind vibration.

[0028] The frame 1 is fixedly connected to a plate 9 at one end and the other end. Both plates 9 have multiple holes 10 at equal intervals. During installation, fasteners such as expansion bolts can be inserted through the holes 10 to firmly fix the device to the installation foundation. The equally distributed holes 10 can flexibly adjust the fixing position to adapt to different foundation pre-embedded points or installation size differences on different sites, ensuring that the device can be stably fixed in different installation scenarios and avoiding structural shaking or displacement caused by unstable installation.

[0029] Specifically, it should be noted that the materials of the frame 1, threaded hole 2, column 3, cavity 4, ball bearing 5, top cover 6, reflective sticker 7, protrusion 8, plate 9, hole 10, and bolt 11 are not limited, as long as they meet the working standards. The ball bearing 5 and cavity 4 need to be cleaned and lubricated regularly, and the connection between column 3 and threaded hole 2 needs to be cleaned and maintained regularly. The specific cleaning cycle and cleaning method can be determined according to the actual use. This case does not impose any restrictions on this, and those skilled in the art should interpret it broadly.

[0030] In use, the multiple threaded holes 2 pre-set on the frame 1 are threadedly connected to the corresponding columns 3, keeping the columns 3 vertical and forming the main body of the fence. Simultaneously, it is ensured that the multiple cavities 4 pre-drilled on the columns 3 are equipped with movable ball bearings 5. These ball bearings 5 ​​within the cavities 4 of the columns 3 can rotate with applied force when personnel come into contact with them, thus providing no stable support and effectively limiting climbing behavior. This also ensures ventilation, visibility, and emergency observation needs, overcoming the shortcomings of existing devices. Next, the top cover 6 is fixedly connected to the top of the frame 1 using bolts 11. The tightening force of the bolts 11 creates an upward limiting constraint on the columns 3 within the frame 1, preventing displacement or detachment from the frame 1 due to upward pulling or vibration during long-term use. The problem is that the overall structural stability of the enclosure device is further enhanced. On the other hand, the bolt 11 connection method facilitates the disassembly and assembly of the top cover 6 during subsequent operation and maintenance, providing operational convenience for the inspection, adjustment or replacement of the column 3. Moreover, the arc-shaped protrusion 8 designed on the top of the top cover 6 can avoid the formation of stress points that are conducive to climbing. Finally, reflective stickers 7 are pasted on the surfaces of both the frame 1 and the top cover 6. In low-light environments such as at night and at tunnel entrances and exits, the reflective stickers 7 can improve the visual recognition of the device through the reflection of light, helping passing personnel and working vehicles to identify the enclosure boundary in time, reducing the risk of collisions caused by poor visibility. Furthermore, the reflective stickers 7 do not require additional energy consumption, which improves the safety warning effect while taking into account the economic efficiency of use, completing the entire process of the device from structural assembly to functional perfection.

[0031] In summary, this urban rail transit safety enclosure device achieves multi-dimensional optimization of urban rail transit safety enclosure through the coordinated operation of a frame, threaded holes, columns, cavities, ball bearings, a top cover, reflective stickers, protrusions, and bolts. Firstly, the multiple threaded holes in the frame are threadedly connected to the corresponding columns to form a guardrail, leveraging the characteristics of the threaded connection to ensure both structural stability and ease of subsequent installation and disassembly. Secondly, the cavities on the vertically placed columns and the ball bearings connected within them allow the ball bearings to rotate under force when personnel come into contact with them, thus preventing them from providing stable support and effectively limiting climbing behavior. This does not obstruct ventilation, visibility, or emergency observation, overcoming the shortcomings of existing devices. Furthermore, the bolts securely connect the top cover to the top of the frame, providing protection for the columns within the frame. The upward limiting constraint prevents the column from shifting or detaching from the frame due to external forces such as upward pulling or vibration during long-term use, further ensuring the overall structural stability of the device. The bolt connection method also facilitates the disassembly and assembly of the top cover during subsequent operation and maintenance, making it convenient to inspect, adjust, or replace the column. The arc-shaped protrusion designed on the top of the cover avoids creating stress points that are easy to climb. The reflective stickers installed on both the frame and the top cover can improve the visual recognition of the device by reflecting light in low-light environments such as at night and at tunnel entrances and exits, helping passing personnel and operating vehicles to identify the enclosure boundary in time, reducing the risk of collisions caused by poor visibility. Moreover, no additional energy consumption is required, which improves the safety warning effect while taking into account economy. The overall structure forms a complementary function and effectively solves the practical problems of safety enclosure in urban rail transit.
