Description

Technical Field

[0001] This utility model relates to the field of rail vehicle technology, and in particular to a protective net device and a rail vehicle. Background Technology

[0002] When a rail vehicle is traveling at low speed or temporarily stopped due to a malfunction, and the doors are open for ventilation, reliable protective devices must be installed in the door area to prevent accidents such as passengers falling, trampling, or items falling onto the tracks. These devices must also meet the requirement of not requiring real-time on-duty personnel to be used, in order to match the characteristics of efficient operation of rail vehicles.

[0003] Currently, the commonly used door safety nets for rail vehicles mainly include two structural types. The first type consists of a frame structure formed by two metal rods and nylon ropes. The metal rods are equipped with clamps for fastening. During installation, tools such as hex wrenches are used to tighten the clamps, securing the safety net to the interior handrails of the vehicle. This structure has the following drawbacks: Firstly, the installation process requires specialized tools, making it cumbersome. Disassembly also requires loosening the clamps one by one, which is time-consuming and labor-intensive, hindering rapid deployment and retrieval in emergency situations. Secondly, the frame structure, composed of metal rods and nylon ropes, is large and rigid, requiring significant space for storage. This necessitates the use of large, centralized storage cabinets in the train, increasing the difficulty of internal space planning and reducing the utilization rate of the carriage space.

[0004] The second type of protective net is a pure woven rope structure, equipped with a simple fixing device. Gravity is used to connect the net's buckles to the car body's sliding track. While this type of net is simple in structure and easy to install, it still has shortcomings in practical applications: First, its reliability is low. Relying solely on gravity to connect the buckles to the track, the buckles are prone to detaching from the track under external forces such as vibrations during rail vehicle operation and passenger collisions, causing the protective net to fail. This is especially problematic in unattended scenarios, where the stability of the protection cannot be guaranteed. Second, its storage convenience is poor. The woven rope is soft and lacks a fixed shape, making it prone to tangling and knotting during storage. Disassembly for reuse requires a significant amount of time, affecting efficiency. Utility Model Content

[0005] This utility model provides a protective net device and a rail vehicle to solve the problem that existing protective nets are difficult to balance in terms of ease of installation, reliability of protection and ease of storage. It designs a protective net device that is simple in structure, easy to store and reliable in use.

[0006] This utility model provides a protective net device for use in rail vehicles. The rail vehicles are equipped with handrails on which the protective net device is installed. The protective net device includes: The protective net includes a mesh body made of woven ropes and a woven fabric covering the surface of the mesh body; The safety net is provided with multiple sets of connecting ropes along its height for connecting with the handrail. Each set of connecting ropes is equipped with the buckle assembly. The buckle assembly includes a fixed buckle and a movable buckle. One end of the fixed buckle and the movable buckle are respectively connected to the connecting rope, and the other end of the fixed buckle and the movable buckle are detachably connected.

[0007] According to the protective netting device provided by this utility model, the fixed buckle is provided with an insertion channel and a locking hole provided at both edges of the insertion channel. The locking hole is connected to the insertion channel. The movable buckle is provided with two spaced buckles. The buckles are configured to engage with the locking hole via the insertion channel.

[0008] According to the protective net device provided by this utility model, the two buckles are elastically arranged, and the fixed buckle and the movable buckle have a locked state and an unlocked state. In the locked state, the two buckles are open and the buckle portion protrudes from the card hole. The two buckles are also configured to move closer to each other to disengage from the insertion channel when pressed by an external force, so that the fixed buckle and the movable buckle switch to the unlocked state.

[0009] According to the protective net device provided by this utility model, the fixing buckle is further provided with a rotating shaft. One end of the rotating shaft is exposed and the other end is located in the insertion channel. The rotating shaft located in the insertion channel is provided with two opposing stop protrusions. The rotating shaft has a first position and a second position. In the first position, the two stop protrusions abut against the inner sides of the two buckles respectively. In the second position, a gap is formed between the buckle and the rotating shaft.

[0010] According to the protective netting device provided by this utility model, the end of the fixing buckle away from the insertion channel is provided with a first connecting hole for hanging the connecting rope; The movable buckle has a second connecting hole at the end away from the buckle, and the connecting rope is movably connected to the second connecting hole so that the length of the connecting rope is adjustable.

[0011] According to the present invention, a set of connecting ropes located at the upper end of the protective net includes two first sub-ropes. The two first sub-ropes are respectively disposed at the two side edges of the protective net. Each first sub-rope is equipped with the buckle assembly. The first sub-rope is used to hang on the upper end of the handrail.

[0012] According to the present invention, a protective net device is provided, wherein the connecting rope located in the middle and / or lower end of the protective net includes a second sub-rope and a third sub-rope. One end of the second sub-rope is connected to one side edge of the protective net and the other end is connected to the fixed buckle. One end of the third sub-rope is connected to the other side edge of the protective net and the other end is connected to the movable buckle. The second sub-rope and the third sub-rope are used to bypass the corresponding handrail and are connected through the fixed buckle and the movable buckle.

[0013] This utility model also provides a rail vehicle, including a car body, a car door and a mounting frame near the car door, with handrails provided on both sides of the mounting frame for installing the protective net device as described above.

[0014] According to the present invention, a rail vehicle is provided with a storage cavity on one side of the mounting frame for storing the folded protective net device.

[0015] According to the present invention, a rail vehicle is provided at the entrance of the storage cavity, and a rotatable protective door is provided on the protective door.

[0016] The protective netting device and rail vehicle provided by this utility model connect the protective netting to the handrail via multiple sets of connecting ropes and buckle components. The fixed buckle and movable buckle adopt a detachable connection structure. During installation, simply attach the connecting rope to the handrail and then directly fasten the fixed buckle and movable buckle to complete the fixation. No special tools such as hex wrenches are required, simplifying the operation steps and allowing a single person to quickly complete the deployment. During disassembly, simply separate the fixed buckle and movable buckle to quickly remove the protective netting, significantly shortening the installation and retrieval time, and making it particularly suitable for the rapid response needs in emergency scenarios.

[0017] Multiple sets of connecting ropes are distributed along the height of the protective net, making the protective net and handrails fixed at multiple points. At the same time, the detachable connection structure of the fixed buckle and the movable buckle is more stable than the pure gravity buckle, which can resist the impact of external forces such as vibration during the operation of the rail vehicle and passenger collisions, effectively preventing the protective net from falling off, ensuring that a continuous and stable protective barrier is formed in the door area, meeting the requirements of use without the need for crew members to be on duty, and reducing the risk of safety accidents.

[0018] The main body of the protective net is made of woven rope and woven fabric. It is soft and has no rigid metal frame. When stored, it can be folded or rolled into a smaller volume, which can reduce storage space and improve the utilization of the car compartment space. At the same time, it avoids the problem of tangled woven ropes during storage. It does not need to be disassembled when used again, further improving the efficiency of use.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] like Figures 1 to 6 As shown, this utility model provides a protective net device applied to rail vehicles. The rail vehicle is equipped with a handrail 200 on which the protective net device is installed. The protective net device includes two parts: a protective net 100 and a buckle assembly 110. The protective net 100 includes a mesh-like main body composed of woven ropes 101 and woven fabric 102 covering the surface of the mesh-like main body. Compared with a simple woven mesh structure, this utility model uses woven ropes 101 and woven fabric 102 sewn together to form an integral structure. On the one hand, it is more robust and durable, reducing the probability of damage and extending the service life. On the other hand, when the protective net 100 is folded or rolled up for storage, it can avoid local rope tangling or knotting, making it convenient to unfold quickly for the next use and improving efficiency. Figure 1As shown, a thicker braided rope 101 can be used around the edge of the mesh body to facilitate the installation of connecting ropes 120 and improve the reliability of the connection. A thinner braided rope 101 can be used in the inner area and combined with woven fabric 102 to form the main protective area.

[0027] The buckle assembly 110 is used to connect the safety net 100 and the handrail 200. In order to ensure the overall flexibility of the safety net 100 after installation, the safety net 100 is provided with multiple sets of connecting ropes 120 along its height direction for connecting with the handrail 200. Each set of connecting ropes 120 is equipped with the buckle assembly 110. The buckle assembly 110 includes a fixed buckle 111 and a movable buckle 112. One end of the fixed buckle 111 and the movable buckle 112 are respectively connected to the connecting rope 120, and the other end of the fixed buckle 111 and the movable buckle 112 are detachably connected. When in use, the connecting rope 120 can be connected to the handrail 200 first, and then fastened by the fixed buckle 111 and the movable buckle 112. Finally, the two sides of the protective net 100 can be hung on the handrails 200 on both sides, thus realizing the quick installation of the protective net 100. When disassembling, the protective net 100 can be quickly removed by separating the fixed buckle 111 and the movable buckle 112. No tools are needed, and the operation is convenient.

[0028] In a preferred embodiment of the present invention, the fixed buckle 111 is provided with an insertion channel 113 and a locking hole 114 located at both edges of the insertion channel 113. The locking hole 114 communicates with the insertion channel 113. The movable buckle 112 is provided with two spaced buckles 115. The buckles 115 are configured to engage with the locking hole 114 via the insertion channel 113.

[0029] like Figure 3 As shown, one end of the insertion channel 113 has an opening for the buckle 115 to enter and exit. The locking hole 114 connects the inside and outside of the insertion channel 113. During operation, the movable buckle 112 moves toward the fixed buckle 111, and the buckle 115 enters the insertion channel 113 through the opening. Then, when the buckle 115 moves to the position of the corresponding locking hole 114, the buckle 115 cooperates with the locking hole 114 to achieve a limit.

[0030] Furthermore, the two buckles 115 are elastically configured, and the fixed buckle 111 and the movable buckle 112 have a locked state and an unlocked state. In the locked state, the two buckles 115 are open and the buckles 115 partially protrude from the latch hole 114. The two buckles 115 are also configured to move closer to each other when pressed by an external force to disengage from the insertion channel 113, so that the fixed buckle 111 and the movable buckle 112 switch to the unlocked state.

[0031] The installation of the movable buckle 112 and the fixed buckle 111 involves two steps. The first step is that the snap buckle 115 moves axially along the fixed buckle 111 until it reaches the locking hole 114. The second step is that the snap buckle 115 expands outwards from the locking hole 114 (i.e., radially along the fixed buckle 111) to achieve engagement. During this process, the distance between the front ends of the two snap buckles 115 changes dynamically. To achieve this distance variation, the two snap buckles 115 are elastically configured. Specifically, the front ends of the two snap buckles 115 have an adjustable distance. For example, in one example, the rear end of the snap buckle 115 is rotatably connected to the corresponding part of the movable buckle 112, and the distance between the two snap buckles 115 can be adjusted by rotating the snap buckle 115 by a certain angle. Alternatively, in another example, an elastic element is provided between the two snap buckles 115, and the distance between the two snap buckles 115 can be adjusted by compressing the elastic element.

[0032] exist Figure 3 In the example, the locking hole 114 is, for instance, V-shaped. When the movable buckle 112 is installed, the two latches 115, after entering the insertion channel 113, are constrained by the shape of the locking hole 114. The two latches 115 first move closer to each other, and then, when they move to face the locking hole 114, they move away from each other and open, thus engaging with the two locking holes 114 respectively, achieving locking. To unlock, press the two latches 115 simultaneously from both sides to bring them closer together, and then pull them out from the insertion channel 113.

[0033] To improve locking stability, prevent unauthorized opening due to operation of the movable buckle 112 by non-staff members, and enhance the reliability of the protective net 100, a protective lock can be further installed to provide double locking, preventing accidental separation of the fixed buckle 111 and the movable buckle 112, and ensuring the protective effectiveness of the protective net 100.

[0034] like Figures 4 to 6 As shown, the fixing buckle 111 is also provided with a rotating shaft 116. One end of the rotating shaft 116 is exposed and the other end is located in the insertion channel 113. The rotating shaft 116 located in the insertion channel 113 is provided with two opposing stop protrusions 117. The rotating shaft 116 has a first position and a second position. In the first position, the two stop protrusions 117 respectively abut against the inner side of the two buckles 115. In the second position, a gap is formed between the buckles 115 and the rotating shaft 116.

[0035] Specifically, the exposed pivot 116 can be rotated using a special tool or key, and can be locked when necessary, such as... Figure 4 As shown, when the pivot 116 is rotated to the first position, the stop protrusion 117 abuts against the inner side of the buckle 115, preventing external pressing and preventing the two buckles 115 from coming close together and disengaging from the insertion channel 113. When unlocking is required, as shown... Figure 5 and Figure 6As shown, when the rotating shaft 116 is rotated to the second position, the stop protrusion 117 rotates 90 degrees or other angles relative to the previous position, creating a gap between the buckle 115 and the rotating shaft 116. The buckle 115 can be pressed normally, thus enabling the insertion and removal of the movable buckle 112. The rotating shaft 116 can be an elliptical shaft or other irregular shaft, which can restrict the pressing of the buckle 115 when rotated at a certain angle.

[0036] It is understood that in other embodiments, when the rotating shaft 116 is rotated to the first position, the stop protrusion 117 may also form a small gap (not abutting) with the buckle 115, which can also play a role in restricting the pressing of the buckle 115.

[0037] This application provides a locking function for the latch assembly 110 by setting a combination structure of a rotating shaft 116 and a stop protrusion 117. The rotating shaft 116 can be easily rotated using a universal four-corner key to lock and unlock the latch assembly 110, ensuring the reliability of the latch lock without sacrificing convenience. The dual locking function fundamentally eliminates safety hazards such as unauthorized opening and accidental loosening, enabling the protective net to be stably applied in unattended working environments and improving the scene adaptability of the protective net.

[0038] Based on the above embodiment, the fixing buckle 111 has a first connecting hole 118 at the end away from the insertion channel 113 for attaching the connecting rope 120. Figure 2 and Figure 3 As shown, the connecting rope 120 and the first connecting hole 118 are connected in a non-adjustable manner, that is, the length of the connecting rope 120 connected to the fixing buckle 111 is fixed.

[0039] The movable buckle 112 has a second connecting hole 119 at the end away from the snap buckle 115. The connecting rope 120 is movably connected to the second connecting hole 119 so that the length of the connecting rope 120 is adjustable. Figure 2 and Figure 3 As shown, a partition shaft 1191 (extending in the same direction as the second connecting hole 119) is provided inside the second connecting hole 119. Gaps are provided on both sides of the partition shaft 1191 between it and the edge of the second connecting hole 119. The connecting rope 120 can be inserted through one gap, pass around the partition shaft 1191, and then exit through the other gap, with a certain length reserved after exiting to allow for adjustment of the rope's length as needed. By making the length of the connecting rope 120 adjustable, it can adapt to the installation requirements of doors of different widths, improving product versatility.

[0040] Based on the above implementation method, in order to achieve the installation of the protective net 100, Figure 1The embodiment provides three sets of installation components, namely, three sets of connecting ropes 120 evenly distributed along the height direction of the protective net 100, and each set of connecting ropes 120 is adapted to a suitable number of buckle components 110 to achieve fixed connection with the handrails 200 on both sides.

[0041] like Figure 1 As shown, a set of connecting ropes 120 located at the upper end of the protective net 100 includes two first sub-ropes 121. The two first sub-ropes 121 are respectively located at the two side edges of the protective net 100. Each first sub-rope 121 is equipped with the buckle assembly 110. The first sub-rope 121 is used to hang on the upper end of the handrail 200.

[0042] Each first sub-rope 121 of the connecting rope 120 is equipped with a buckle assembly 110. Taking one of the first sub-ropes 121 as an example, the first sub-rope 121 includes two sections. One end of the first section is led out from the braided rope 101 at the top of the protective net 100 (the first section and the corresponding braided rope 101 can be an integral structure). The other end of the first section is connected to the fixed buckle 111. One end of the second section is connected to the movable buckle 112, and the other end is provided with a ring sleeve. The ring sleeve can be directly put on the upper end of the handrail 200 (the handrail 200 is provided with a crossbar near the top to prevent the ring sleeve from sliding down).

[0043] Furthermore, the connecting rope 120 located in the middle and lower part of the protective net 100 includes a second sub-rope 122 and a third sub-rope 123. One end of the second sub-rope 122 is connected to one side edge of the protective net 100 and the other end is connected to the fixed buckle 111. One end of the third sub-rope 123 is connected to the other side edge of the protective net 100 and the other end is connected to the movable buckle 112. The second sub-rope 122 and the third sub-rope 123 are used to bypass the corresponding handrail 200 and are connected through the fixed buckle 111 and the movable buckle 112.

[0044] The middle and lower connecting ropes 120 have the same structure, and each set of connecting ropes 120 is equipped with a buckle assembly 110. For example... Figure 1 As shown, the second sub-rope 122 and the third sub-rope 123 are longer than the first sub-rope 121. The second sub-rope 122 and the third sub-rope 123 are connected by a fixed buckle 111 and a movable buckle 112 after passing around the corresponding handrail 200, which is convenient for direct operation from the side of the handrail 200 without having to slip it on from the top of the handrail 200, thus simplifying the operation process and improving the convenience of operation.

[0045] It is understandable that the length of each sub-rope connected to the movable buckle 112 can be adjusted to adapt to the installation requirements of doors of different widths, thereby improving versatility and adaptability.

[0046] When installing the protective net 100, the operation can be carried out from top to bottom. For example, first, put the loop on the handrail 200, then install the fixed buckle 111 and movable buckle 112 corresponding to the first sub-rope 121, then wrap the middle set of second sub-ropes 122 and third sub-ropes 123 around the handrail 200 and connect the fixed buckle 111 and movable buckle 112, and finally install the lower set of second sub-ropes 122 and third sub-ropes 123. The operation method is the same as above. During the specific operation, the length of some connecting ropes 120 can be adjusted in real time as needed to ensure that the protective net 100 is properly tensioned, and the installation of the protective net 100 is completed.

[0047] It is understood that the connecting rope 120 is not limited to three sets. For example, in other embodiments, only one set of connecting rope 120 is provided at each of the upper and lower ends of the protective net 100, or in other embodiments, four or more sets of connecting rope 120 are provided.

[0048] This utility model also provides a rail vehicle, including a car body, a car door and a mounting frame 210 near the car door. Handrails 200 are provided on both sides of the mounting frame 210 for installing the protective net device described in the above embodiments and examples.

[0049] In some embodiments, a storage cavity is provided on one side of the mounting frame 210 for storing the folded protective net device.

[0050] The protective netting device of this utility model has a flexible structure, which makes it easy to fold or roll up for storage. After folding or rolling, it has a small volume and can make full use of the internal space of the mounting frame 210 to provide a small storage cavity, thus satisfying the storage of the protective netting device while improving space utilization.

[0051] Furthermore, a rotatable protective door is provided at the entrance of the storage cavity, and a viewing window is provided on the protective door.

[0052] The protective door is used to seal and protect the storage cavity, providing dust and water protection and preventing the loss of the protective netting device. A viewing window allows staff to observe the storage status of the protective netting device inside the cavity, ensuring quick access when needed and achieving effective protection.

[0053] The protective netting device and rail vehicle provided by this utility model are as follows: the protective netting 100 is connected to the handrail 200 by multiple sets of connecting ropes 120 and buckle components 110. The fixed buckle 111 and the movable buckle 112 adopt a detachable connection structure. During installation, it is only necessary to attach the connecting rope 120 to the handrail 200 and then directly fasten the fixed buckle 111 and the movable buckle 112 to complete the fixation. No special tools such as hex wrenches are required, simplifying the operation steps and allowing a single person to quickly complete the deployment. During disassembly, it is only necessary to separate the fixed buckle 111 and the movable buckle 112 to quickly disassemble the protective netting 100, which greatly shortens the installation and retrieval time and is especially suitable for the rapid response needs in emergency scenarios.

[0054] Multiple sets of connecting ropes 120 are distributed along the height of the protective net 100, so that the protective net 100 and the handrail 200 are fixed at multiple points. At the same time, the detachable connection structure of the fixed buckle 111 and the movable buckle 112 has stronger connection stability than the pure gravity buckle. It can resist the impact of external forces such as vibration during the operation of the rail vehicle and passenger collision, effectively prevent the protective net 100 from falling off, ensure that a continuous and stable protective barrier is formed in the door area, meet the usage requirements of not requiring the presence of crew members, and reduce the risk of safety accidents.

[0055] The protective net 100 is mainly composed of braided rope 101 and braided fabric 102. It is soft and has no rigid metal frame. When stored, it can be folded or rolled into a smaller volume, which can reduce storage space and improve the utilization rate of the carriage space. At the same time, it avoids the problem of the braided rope 101 getting tangled during storage. It does not need to be disassembled when used again, further improving the efficiency of use.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
