Description

Technical Field

[0001] This invention relates to the field of train wiring technology, and in particular to a wiring device for trains and its operating method. Background Technology

[0002] As a core component of modern urban public transportation systems, the complexity and reliability of the internal electrical systems of urban rail vehicles directly affect the safe operation and efficiency of trains. During the manufacturing and assembly of urban rail vehicles, the arrangement of onboard cables is an extremely critical and tedious process. Shielded cables are mainly used to transmit sensitive control signals or communication data. Their unique metal braided or shielding layers are designed to effectively resist interference from the complex electromagnetic environment inside and outside the vehicle, ensuring the accuracy and stability of signal transmission. 110V low-voltage cables typically power the vehicle's control circuits, lighting, door control, and other low-voltage equipment. They are characterized by relatively small current, but require extremely high stability and safety of the lines. 380V cables are mainly used to drive relatively high-power AC loads such as air conditioning units and air compressors. Their wiring must fully consider factors such as voltage drop, heat generation, and electrical isolation.

[0003] The equipment installation locations and wiring point distributions differ significantly between the lead car and intermediate cars. The lead car typically houses critical devices such as the driver's cab control panel, core signal processing equipment, and traction control unit, resulting in more complex cable connections. In contrast, intermediate cars primarily house passenger compartment equipment and auxiliary power systems. This structural asymmetry dictates that a uniform pre-wiring scheme cannot be adopted; separate, customized pre-wiring designs must be developed for each car. Therefore, separate pre-wiring is required for the lead car and intermediate cars. Taking a typical six-car urban rail train as an example, a train usually consists of two lead cars and four intermediate cars. Based on the aforementioned differences between the lead car and intermediate cars… Due to the differences in train models and the inherent directionality of the vehicles (i.e., the two sides of the direction of travel are defined as "first side" and "second side"), the pre-wiring work for the entire train is broken down into as many as 12 different key work locations. Specifically, each lead car and each intermediate car has a first side and a second side. Within each of these sides, wiring engineers need to independently lay and install three types of wire harnesses: 110V wires, 380V wires, and shielded cables. This means that, for just one complete train, the basic pre-wiring work points reach 2 types of train models × 2 sides × 3 types of wire harnesses = 12 core wiring areas.

[0004] Because the wiring is done from above the vehicle, the handling, laying, and securing of cables, as well as the precise assembly and calibration of connectors, cannot be carried out efficiently in a streamlined process. The pre-wiring at 12 locations means a large amount of repetitive labor and process changes, with a high proportion of preparation and auxiliary time, resulting in a long overall wiring cycle and making it a bottleneck station on the vehicle final assembly line. Summary of the Invention

[0005] The purpose of this invention is to provide a wiring device and its working method for trains, which solves the problems of low work efficiency, inconvenience of operation, and low standardization of wire harnesses after wiring, which are carried out by looking up from the train and performing wiring, connector assembly, wire alignment, and protection on both sides of the inner side wall of the train alone.

[0006] To achieve this objective, the present invention adopts the following technical solution: The present invention provides a wiring device for trains, including a positioning frame, a laying component installed on the upper side of the positioning frame, a nameplate installed on the laying component, a positioning post installed at one end of the positioning frame, limit posts installed on both sides of the positioning frame, a wire being laid from the positioning post, the wire being laid along the length direction of the positioning frame, the nameplate corresponding one-to-one with the wire, and the nameplate being marked with the laying length information of the wire, the position of the wire, and the type of the wire.

[0007] Preferably, the laying component includes a wooden board, the positioning frame is rectangular, and the wooden board is overlapped within the rectangular frame formed by the positioning frame.

[0008] Preferably, the laying assembly further includes a crystal plate, which is laid on the upper side of the wooden board. Along the wire laying direction, the width of the crystal plate perpendicular to the wire laying direction is greater than the width of the rectangular frame.

[0009] Preferably, the crystal plate has a through hole, and the limiting post passes through the through hole.

[0010] Preferably, the laying assembly further includes a thin plate with a textured surface and a barbed surface on the back of the nameplate, and the nameplate is adhered to the thin plate.

[0011] Preferably, the limiting post is made of aluminum alloy and is welded to both sides of the positioning frame.

[0012] Preferably, a rubber sleeve is fitted onto the limiting post.

[0013] Preferably, one end of the positioning frame is provided with a slide rail, and the positioning post is slidably installed on the slide rail, with the positioning post sliding perpendicular to the wire laying direction.

[0014] Preferably, the positioning frame is constructed by overlapping aluminum materials, and the positioning frames can be connected to each other.

[0015] A method for operating a wiring device for a train, comprising the wiring device for a train as described above, and further comprising the following steps:

[0016] S1, connect the positioning frames to the length of the target train;

[0017] S2, Place the laying components on the positioning frame;

[0018] S3, place the nameplate on the laying component, with the distance between the nameplate and the positioning post being the same as the information marked on the nameplate;

[0019] S4, lay the corresponding wire from one side of the positioning column to the nameplate position and extend it to both sides of the positioning frame with the reserved length, and mark the extended length on the nameplate;

[0020] S5. After bundling the wires, attach a mesh bag to the outside of the wires, and finally check the wires.

[0021] Beneficial effects: The wires are pre-arranged on the positioning frame, eliminating the need for manual overhead wiring work inside the vehicle. At the same time, the reserved length of the wires can be marked by the nameplate, which facilitates the pre-fixing of wires for the same vehicle model, shortens the wiring time, and reduces the workload of workers.

[0028] The present invention will now be described in further detail 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 not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0029] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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 or an electrical 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 invention based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] Under current technology, the reliability of the electrical system inside urban rail vehicles is directly related to train safety and operational efficiency. Among these, the cabling layout is a critical and complex process. Shielded wires are used to transmit sensitive signals, and their shielding layer can resist electromagnetic interference; 110V low-voltage wires power control circuits, lighting, etc., and have high stability requirements; 380V wires are used for AC loads such as air conditioners and air compressors, and the wiring must consider voltage drop and electrical isolation.

[0033] Due to significant differences in equipment layout between the lead car and intermediate cars, a unified pre-wiring scheme cannot be adopted. The lead car houses critical equipment such as the driver's cab and signal processing equipment, making cable connections more complex; the intermediate cars primarily house passenger compartment equipment. Therefore, customized pre-wiring designs are required for each type of train. Taking a six-car train (two lead cars + four intermediate cars) as an example, considering the directionality of the "first side" and "second side" of the vehicles, a total of 12 key wiring locations are identified throughout the train: each car has two sides, and each side requires the laying of three types of wiring harnesses: 110V wire, 380V wire, and shielded wire. That is, 2 types of trains × 2 sides × 3 types of wiring harnesses = 12 core operating areas.

[0034] This process is limited by the overhead working space inside the vehicle, resulting in low automation and reliance on manual labor. Workers often have to operate in non-standard positions, such as looking upwards, which restricts their movement. The processes of cable handling, laying, fixing, and connector assembly are highly repetitive and involve frequent changes, with preparation and auxiliary time accounting for a large proportion, leading to a long overall wiring cycle and becoming a bottleneck in the final assembly line.

[0035] To solve the above problems, such as Figures 1 to 5 As shown, the present invention provides a wiring device for trains, including a positioning frame 1, a laying component installed on the upper side of the positioning frame 1, a nameplate 2 installed on the laying component, a positioning post 3 installed at one end of the positioning frame 1, limit posts 7 installed on both sides of the positioning frame 1, a wire 4 being laid from the positioning post 3, the wire 4 being laid along the length direction of the positioning frame 1, the nameplate 2 corresponding to the wire 4 one-to-one, and the nameplate 2 being marked with the laying length information, the position of the wire 4 and the type of the wire 4.

[0036] The nameplate 2 usually indicates the location of wire 4, that is, whether wire 4 is located on the first or second side. The nameplate 2 also indicates the type of wire 4 and the information of the components it connects to. Most importantly, the nameplate 2 indicates the distance from the positioning post 3 and the reserved length. The position of the nameplate 2 from the positioning post 3 is the location of wire 4, which also represents the length of wire 4 that needs to be laid. The reserved length of wire 4 is to be thrown out from the nameplate 2 to the nearest side of the positioning frame 1 for connection with the components. The nameplate 2 is placed on the laying component. The operator can directly select wire 4 for laying based on the information on the nameplate 2. The worker stands on one side of the positioning frame 1 and selects wire 4 for laying. There is no need to look up to work, which reduces the labor intensity. At the same time, it can also improve the efficiency of wiring and the standardization of wiring harness. After the wiring is completed, wire 4 can be directly laid into the wire grooves on both sides of the inner side wall of the vehicle.

[0037] Meanwhile, limit posts 7 are usually installed on both sides of the wiring direction of the positioning frame 1. The limit posts 7 can prevent the wire 4 from falling and improve the wiring efficiency.

[0038] The laying assembly of the present invention includes a wooden board 5, a rectangular positioning frame 1, and the wooden board 5 is attached to the rectangular frame formed by the positioning frame 1.

[0039] The laying assembly of this invention mainly consists of two parts: wooden boards 5 and a positioning frame 1. The positioning frame 1 is designed as a rectangular structure, and the wooden boards 5 are laid on the upper side of the rectangular area enclosed by the frame. In actual laying, the wooden boards 5 are usually divided into two groups, representing the "first side" and the "second side," respectively. The two groups of wooden boards 5 are arranged parallel to each other on the positioning frame 1. Each wooden board 5 serves as a supporting base for a specific wire 4. For example, the wooden boards 5 on the first side are used to lay multiple types of wires 4, while the wooden boards 5 on the second side are used to place other wires 4, thereby structurally achieving orderly placement and zoned management of the wires 4.

[0040] The design of this cable laying assembly offers several practical advantages. First, the wooden board 5, acting as a supporting medium, provides a stable foundation for the cables 4, effectively preventing displacement, sagging, or tangling during construction or use, thus enhancing the overall stability and safety of the cable system. Second, this clearly defined zoning method greatly facilitates cabling operations for construction workers. Workers can accurately and efficiently lay different types of cables 4 to their corresponding areas based on the markings on the wooden board 5, reducing the probability of cabling errors and improving work efficiency. Furthermore, this structure facilitates subsequent positioning and fixing of the cables 4, maintaining a neat and aesthetically pleasing cable arrangement and providing better conditions for system inspection and maintenance.

[0041] In summary, this cable laying assembly, through the cooperation of the wooden board 5 and the positioning frame 1, not only strengthens the physical support for the cable 4, but also optimizes the cabling process, making it a cable laying solution that balances practicality, reliability, and ease of construction.

[0042] The laying assembly also includes a crystal plate 6, which is laid on the upper side of the wooden board 5 along the laying direction of the wire 4. The width of the crystal plate 6 perpendicular to the laying direction of the wire 4 is greater than the width of the rectangular frame. The crystal plate 6 is usually made of flexible material. It is placed on the upper side of the wooden board 5 to protect the wire 4 placed on the upper side of the crystal plate 6. At the same time, the crystal plate 6 hangs on both sides of the laying assembly. The wire 4 will have a certain length reserved on both sides of the positioning frame 1. The crystal plate 6 can protect the wire 4 from being scratched by the top edge of the positioning frame 1.

[0043] The crystal plate 6 has a through hole, and the limiting post 7 is inserted into the through hole. Since the width of the crystal plate 6 is greater than the width of the positioning frame 1, in order to prevent the crystal plate 6 from lifting at the edge of the positioning frame 1, the limiting post 7 is inserted through the crystal plate 6 so that the crystal plate 6 can be laid flat, which is convenient for the laying of the wire 4.

[0044] The laying components also include a thin plate 8 with a textured surface and a nameplate 2 with a barbed surface on the back. The nameplate 2 is adhered to the thin plate 8. The thin plate 8 should have a certain thickness and flexibility. A 2mm thick floor cloth can be used as the thin plate 8. The thin plate 8 is cut to a length of 24m and a width of 0.2m. The label is attached to the thin plate 8 using tape. The thin plate 8 can be adhered to the nameplate 2 through the textured surface, which facilitates subsequent disassembly and replacement, or changes in the position of the nameplate 2 to adapt to different train models, or changes in the placement of the nameplate 2 according to different train electrical layouts. Alternatively, the nameplate 2 can be made of printed paper and adhered to the thin plate 8 with tape. After the wiring is completed, the thin plate 8 can be rolled into a roll for easy storage. When used again, it can be directly unfolded to shorten the laying time and improve wiring efficiency.

[0045] In the laying assembly involved in this invention, the limiting post 7 and the positioning frame 1 are the core structures that realize its modular and expandable functions. The limiting post 7 is preferably made of aluminum alloy and is firmly connected to both sides of the positioning frame 1 through welding. This design makes full use of the characteristics of aluminum alloy material. Its advantages of being lightweight and high-strength ensure the overall structural stability while greatly reducing the weight of the component, bringing significant convenience to handling and on-site assembly. In addition, aluminum alloy has excellent corrosion resistance and can effectively cope with complex working conditions such as moisture and vibration that may be encountered during train operation, thereby ensuring long-term reliability.

[0046] The positioning frame 1 itself is also made of aluminum alloy profile, and the overall design adheres to the modular concept. Each positioning frame 1 can be used as an independent module, and can be quickly and accurately assembled through specially designed connecting components. In practical applications, construction personnel can assemble multiple positioning frames 1 end to end according to the wiring length requirements of a specific train model. This invention has a high degree of configuration flexibility, and different wiring distances can be adapted by increasing or decreasing the number of frames. For example, when dealing with extreme wiring requirements of up to approximately 24 meters, a solution consisting of 12 standard positioning frames 1 can be used. This "assemble-on-demand" feature avoids the problems of high cost, poor flexibility, and inconvenient storage caused by traditional customized long-size tooling.

[0047] The assembled structure forms an extended and orderly wiring channel with a uniform width of 0.8 meters. This width, rigorously calculated and verified in practice, is key to achieving "pre-wiring under the vehicle" while meeting the space requirements for accommodating various types and multiple cables, and also taking into account the strict limitations of the limited installation space under the vehicle.

[0048] In summary, this component, through the reinforced positioning of the aluminum alloy limiting post 7 and the flexible splicing of the modular positioning frame 1, together constructs a robust, lightweight, and freely expandable cable support system. It successfully transforms what could have been a cumbersome and complex long-distance under-vehicle cabling project into a series of standardized and easily managed on-site assembly operations. This not only significantly improves cabling efficiency and accuracy but also provides lasting convenience for subsequent cable inspection, maintenance, and even system upgrades.

[0049] The limiting post 7 is fitted with a rubber sleeve, which can prevent the sharp surface of the limiting post 7 from being cut, reduce damage to the wire harness, and improve safety. The limiting post 7 is usually a post structure with a height of 120mm, a width of 20mm, and a thickness of 4mm.

[0050] The positioning frame 1 is equipped with a slide rail 9 at one end, and the positioning post 3 is slidably installed on the slide rail 9. The positioning post 3 slides perpendicular to the laying direction of the wire 4. By setting the positioning post 3, the placement position of the wire harness on the laying component can be adjusted to improve safety.

[0051] The positioning frame 1 is made of aluminum materials and can be connected to each other. The frame is 2m long, 0.8m wide and 0.8m high. The structure is simple and easy to mass-produce.

[0052] The present invention also provides a method for operating a wiring device for a train, comprising the following steps:

[0053] S1, Connect the positioning frames 1 to each other to the length of the target train;

[0054] S2, Place the laying components on the positioning frame 1;

[0055] S3, place nameplate 2 on the laying component, the distance between nameplate 2 and positioning post 3 is the same as the information marked on nameplate 2;

[0056] S4, lay the corresponding wire 4 from one side of the positioning column 3 to the nameplate 2 position and extend it to both sides of the positioning frame 1 with a reserved length. The extended length is marked on the nameplate 2. In addition, on the side of the positioning column 3 away from the positioning frame 1, the length of the wire 4 to be connected to the equipment cabinet needs to be reserved. The length is marked on the nameplate 2 starting from the positioning column 3.

[0057] S5, after bundling wire 4, attach a net bag to the outside of wire 4, and finally check wire 4.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
