Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit technology, and more specifically, to a trackside cabinet. Background Technology
[0002] With the rapid development of rail transit, especially the development of subway signaling systems, there are diverse demands for trackside cabinets, which are essential components of signaling systems.
[0003] Currently, there are two types of cabling methods for the equipment rooms of urban rail signaling systems: one is bottom entry and bottom exit (underground cabling), where cables are laid under the anti-static floor of the equipment room; the other is top entry and top exit (upper cabling), where cables are laid in the cable tray boxes of the equipment room. The specific method used needs to be determined based on a comprehensive consideration of factors such as indoor space, maintenance requirements, safety, and aesthetics.
[0004] Currently, the cable entry and exit methods for trackside cabinets in domestic subway signaling systems are mostly based on under-cabinet routing. In some projects, to meet the requirements for overhead cabling, holes are drilled directly in the top of existing standard cabinets for cable entry, with the cable trays pressed against the top of the cabinet. In other projects, to accommodate top-outlet cabling, a slot is cut into the front of the top plate of the cabinet, but this is only suitable for situations where there are relatively few devices inside the cabinet. Utility Model Content
[0005] A brief overview of the present invention is given below to provide a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the present invention. It is not intended to identify key or essential parts of the present invention, nor is it intended to limit the scope of the present invention. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.
[0006] This disclosure provides a trackside cabinet. The trackside cabinet includes a housing for accommodating signaling equipment and cables.
[0007] The cabinet is deeper than a standard cabinet, forming a cable storage space inside the cabinet. The cabinet includes a top plate and a bottom plate.
[0008] The top plate has two elongated slots extending along the depth of the cabinet. Each slot is covered by one or more sliding covers, which are slidable back and forth along the slots to create openings in the top plate, serving as cable inlets and outlets.
[0009] The base plate adopts a modular design, and its length is adapted to the depth of the cabinet.
[0010] According to an embodiment of this disclosure, the railside cabinet features cable entry and exit channels on both sides of the top, and utilizes a sliding cover that moves back and forth to achieve adjustable cable entry points, accommodating various cable quantities and sizes. The increased cabinet depth creates dedicated space for cable routing without affecting the cabinet's equipment storage capacity.
[0011] The two slots are symmetrically arranged on both sides of the rear part of the top plate.
[0012] This symmetrical arrangement provides balanced cable entry points, helps to distribute cable load evenly and maintain the cabinet's center of gravity, while also providing flexibility for cabling from either side of the cabinet.
[0013] The length of the two slots is set according to the expected number and size of cables to be inserted into the cabinet.
[0014] In this way, the appropriate slot size can be set according to needs.
[0015] The length of the two slots is less than the depth of the cabinet.
[0016] This design choice allows for a solid section at the front of the top panel, enhancing the structural integrity of the cabinet and ensuring that cable entry points are located at the rear of the cabinet.
[0017] The cable accommodating space is used to accommodate the power cables, signal cables, and control cables inside the trackside cabinet for vertically separated wiring.
[0018] Dedicated vertical cable routing space is easy to operate and maintain, and also helps manage cable bending radius, extending cable life and improving performance.
[0019] The cable accommodating space is equipped with multiple cable clamps, which are configured to secure power cables, signal cables, and control cables respectively. The cable clamps are fixed to the mounting plate of the cabinet.
[0020] This method enhances cable organization and management within the cabinet. Using cable clips also helps maintain proper cable tension and prevents stress on connections.
[0021] The base plate is configured to allow cables to enter from the bottom, enabling the railside cabinet to accommodate both top and bottom cable entry.
[0022] This dual-entry capability significantly improves the flexibility of rack design, enabling it to adapt to various installation environments and cabling requirements.
[0023] The cabinet can be 600 mm wide, 800 mm deep, and 2200 mm high.
[0024] These specific dimensions strike a balance between increased functionality and space efficiency. The 800 mm depth provides ample space for cable accommodating while maintaining a relatively compact footprint suitable for railside installation. Attached Figure Description

[0034] According to the embodiments of this disclosure, without changing the existing equipment layout in the trackside cabinet, a solution is proposed to solve the problems of cable entry and exit and cable arrangement in the cabinet, which can meet the railway industry standards.
[0035] The solution of this utility model can accommodate various cabinet structures in the indoor cabinets of railway signaling systems, including interlocking cabinets, ATP (Automatic Train Protection) cabinets, and relay cabinets, all of which can meet the requirements for overhead wiring.
[0036] The trackside cabinet according to an embodiment of the present disclosure will now be described with reference to the accompanying drawings.
[0037] Figure 1 This is a simplified perspective view of the trackside cabinet 10 according to an embodiment of the present disclosure. Figure 1 As shown, the trackside cabinet 10 includes a cabinet body 100.
[0038] The cabinet 100 constitutes the main structure of the rack, providing support and protection for the internal components and accommodating various signal devices and cables. For the sake of brevity, this disclosure primarily describes the innovative aspects of the cabinet structure, omitting descriptions of the various components inside the cabinet, such as the multi-function board, shielding board, and signal devices.
[0039] In an embodiment according to this disclosure, the cabinet depth D is increased compared to a standard cabinet to form a cable-receiving space within the cabinet body.
[0040] For example, the depth of a standard cabinet is generally 600 mm, while the depth of a railside cabinet according to an embodiment of this disclosure can be 800 mm.
[0041] The increased cabinet depth provides additional internal space for cable routing and operational maintenance. This space, located at the rear of the cabinet, allows for vertical cable routing without interfering with various devices installed at the front of the cabinet.
[0042] The cabinet 100 includes a top plate 102 and a bottom plate 104.
[0043] In this disclosure, for the sake of brevity, the structural features of the top and bottom panels of the cabinet are mainly described, while the descriptions of the side panels, front panels, back panels and other components of the cabinet are omitted.
[0044] The top plate 102 is provided with two elongated slots 1022, which extend along the depth of the cabinet. Each slot 1022 is covered by one or more sliding covers 1024, which can slide back and forth along the slots 1022 to form openings on the top plate 102 as cable inlets and outlets.
[0045] Figure 1 The upper left side schematically shows at least one sliding cover 1024 sliding along the slot 1022, forming an opening in the top plate 102.
[0046] Figure 2 This is a simplified schematic top view of a trackside cabinet according to an embodiment of the present disclosure. Figure 2 The right side schematically shows at least one sliding cover 1024 sliding along the slot 1022, forming an opening in the top plate 102.
[0047] Two slots 1022 are parallel to the side edges of the top plate 102 and are symmetrically arranged on both sides of the rear of the top plate 1022. The length of each slot 1022 can be set according to the expected number and size of the cables to be inserted into the cabinet 100. The length of the two slots 1022 is less than the depth of the cabinet 100.
[0048] This design allows for a solid section at the front of the top panel 102, enhancing the structural integrity of the cabinet. Simultaneously, it ensures the cable entry point is located at the rear of the cabinet, utilizing the internal cable-receiving space to accommodate cables and improving the management of bending radii when cables transition from vertical to horizontal cabling.
[0049] The sliding cover 1024 is designed to fit the slot, and one or more sliding covers can be installed as needed. For example, three sliding covers can be installed, and the size of the resulting opening can be flexibly controlled by moving the sliding covers to a two-overlapping state or a three-overlapping state. The adjustable opening size allows cables of different diameters and numbers to pass through without requiring permanent modifications to the cabinet structure.
[0050] Understandable. Figures 1-2 The three sliding covers shown are merely illustrative examples, and the number of sliding covers is not limited in this disclosure.
[0051] Figure 3 This is a simplified schematic bottom view of a trackside cabinet according to an embodiment of the present disclosure.
[0052] The base plate 104 adopts a modular design, and its length is adapted to the depth of the cabinet 100.
[0053] In this embodiment of the disclosure, the base plate 104 adopts a modular design. For example, it can use one or more existing modules with cable inlets, and then combine them with a module that can adapt to the depth of the cabinet.
[0054] This base plate design accommodates the increased depth of the cabinet while allowing cable entry at the bottom, enabling the railside cabinet to accommodate both top and bottom cable entry.
[0055] This dual-entry capability significantly improves the flexibility of rack design, enabling it to adapt to various installation environments and cabling requirements, reducing the need for different rack models for different scenarios.
[0056] In the embodiments according to this disclosure, the increased cabinet depth forms a cable accommodating space within the cabinet. This cable accommodating space is used to accommodate power cables, signal cables, and control cables in the railside cabinet for vertically separated wiring, and facilitates operation and maintenance.
[0057] When installing vertical cabling, existing cabinet mounting plates and shielding plates can be used to secure cable clamps. Cables are arranged along both sides of the cabinet and secured with cable clamps. The cable clamps both support the weight of the cables and prevent them from twisting.
[0058] Preferably, the power cable, signal cable, and control cable can be fixed separately using cable clamps.
[0059] In a preferred embodiment of this disclosure, the railside cabinet has a width of 600 mm, a depth of 800 mm, and a height of 2200 mm. These specific dimensions strike a balance between increased functionality and space efficiency. The 800 mm depth provides ample space for cable management while maintaining a relatively compact footprint suitable for railside installation. The 2200 mm height allows for substantial equipment storage capacity. The cabinet dimensions are designed to balance equipment capacity, ease of installation, and maintainability, while also adapting to site constraints. Adjustments can be made to specific project requirements, which will not be elaborated upon here.
[0060] According to the embodiments of this disclosure, the trackside cabinet features cable entry and exit channels on both sides of the top of the cabinet, increasing cable capacity. A sliding cover allows for adjustable cable entry points, accommodating various cable quantities and sizes. The increased cabinet depth provides dedicated space for cable routing without affecting the cabinet's equipment storage capacity. Cables are routed on both sides of the rear of the cabinet, without affecting the existing equipment layout in a standard cabinet. These two cable entry and exit channels correspond to and match overhead cable trays, facilitating installation and reducing the need for additional cable conduits and cables. This saves costs and reduces installation and maintenance cycles. It is suitable for installation in indoor equipment rooms under various complex environmental conditions, offering high reliability.
[0061] The embodiments of this disclosure are a new type of trackside cabinet designed to meet the increasing demand for overhead cabling in subway signaling systems. The cabinet adopts a modular design and features high versatility, high scalability, and high compatibility. It can flexibly meet different cabling requirements according to customer and environmental needs, saving design cycle and design costs.
[0062] The cabinet allows for flexible switching between top-cabinet and bottom-cabinet configurations through the combination of different structural components. The internal equipment layout remains unchanged, thus preserving the cabinet's manufacturing process and installation / maintenance methods while maintaining its original performance specifications. It can adapt to installations in various complex environments, minimizing project investment costs.
[0063] The cabinets according to embodiments of this disclosure support both top and bottom cabling methods, simultaneously meeting the overhead cabling requirements of various cabinets. The addition of cabinets of different sizes enriches the types of trackside cabinets for subway signaling systems, satisfying the needs of customers and partners for different cabling methods and cabinet sizes.
