Abstract
Description
Technical Field
[0001] This utility model relates to the field of rail transit signaling equipment technology, specifically to a chassis for trackside signaling equipment. Background Technology
[0002] Trackside signaling equipment is a key component of railway signaling systems, typically installed beside railway tracks to perform functions such as train position detection, signal transmission, and control. The core electronic units of this equipment need to be housed in a protective enclosure to withstand rain, dust, vibration, and extreme temperatures. Existing trackside signaling equipment enclosures usually include a sealed housing, a lockable door, and necessary heat dissipation structures. The bottom of the enclosure typically has a flat mounting base with bolt holes for securing it in place. The enclosure is then firmly installed in the designated location using bolts pre-embedded in a concrete foundation or pre-mounted on a metal bracket.
[0003] However, in actual construction and installation, due to errors in civil engineering, the position of the embedded bolts often deviates to some extent. When the relative position of the embedded bolts does not perfectly match the position of the fixing bolt holes on the chassis mounting base, the chassis cannot be installed smoothly. Installers often need to enlarge the holes on-site, hammer and adjust, or even redo the civil engineering work. This process is time-consuming and labor-intensive, seriously affecting installation efficiency, and sometimes even affecting the overall protective performance of the chassis due to damage to the structure of the mounting base. Utility Model Content
[0004] The purpose of this utility model is to provide a chassis for trackside signaling equipment, so as to solve the problem that the existing trackside signaling equipment chassis cannot adapt to the position deviation of the pre-embedded bolts due to the fixed position of the mounting base bolt holes, resulting in difficult on-site installation and low efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a chassis for trackside signal equipment, comprising a chassis body and a door, wherein the door is connected to the chassis body via a hinge, and the bottom of the chassis body is provided with a mounting base, wherein the mounting base comprises a horizontally arranged base plate and at least two vertically fixed mounting wing plates on the lower surface of the base plate, and the mounting wing plates are provided with elongated mounting holes;
[0006] The side panel of the enclosure is provided with a heat dissipation structure for ventilation of the internal components. The interior of the enclosure is provided with multiple layers of spaced support plates, and electrical components are mounted on the support plates.
[0007] Furthermore, the mounting base is integrally formed from a metal sheet through a bending process, and there are two mounting wing plates, which are located on both sides of the mounting base along its length.
[0008] Furthermore, the length direction of the elongated mounting hole is consistent with the length direction of the mounting base, and the number of elongated mounting holes opened on the same mounting wing plate is not less than two, and the mounting holes on the two mounting wing plates are positioned opposite each other.
[0009] Furthermore, a locking component is provided on the base plate, and a threaded hole that mates with the locking component is provided at the bottom of the housing. The mounting base is detachably connected to the housing through the engagement of the locking component and the threaded hole.
[0010] Furthermore, the heat dissipation structure is in the form of louvers, and the inner side of the louvers is provided with a vertical waterproof and breathable membrane.
[0011] Furthermore, the inner wall of the enclosure is fitted with an electromagnetic shielding pad, which is conductive rubber or a metal spring.
[0012] Furthermore, a sealing strip is provided on the inner periphery of the box door, and a guide plate is provided on the top plate of the box body, the vertical cross-section of the guide plate being inverted V-shaped.
[0013] Compared with existing technologies, the present invention provides a chassis for trackside signaling equipment. By adopting a mounting base consisting of a horizontal base plate and vertically downward extending mounting wing plates, and opening elongated mounting holes on the wing plates, the chassis provides positional adjustment margin in at least one direction in the horizontal plane, enabling the chassis to have horizontal installation adjustment capability. When the position of the pre-embedded bolts deviates, the installer can loosen the nuts and move the chassis within the range of the elongated holes to align it with the bolts, thereby achieving fast, non-destructive, and precise alignment installation, effectively compensating for foundation construction errors and improving installation efficiency.
[0014] Meanwhile, through the rational layout of the internal multi-layer mounting plates and the organic combination of the side plate's efficient heat dissipation structure, the multi-layer mounting plates provide a modular and high-capacity installation platform for electrical components, facilitating maintenance and management; while the heat dissipation structure design ensures the long-term stable operation of the equipment in harsh environments, jointly improving the comprehensive performance and engineering practical value of the trackside signal equipment chassis.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] As attached Figure 1 To be continued Figure 4 As shown:
[0024] Example:
[0025] This utility model provides a chassis for trackside signaling equipment, including a chassis body 1 and a chassis door 2. The chassis door 2 is connected to the chassis body 1 by a hinge 3. The bottom of the chassis body 1 is provided with a mounting base 4. The mounting base 4 includes a horizontally arranged base plate 401 and at least two mounting wing plates 402 vertically fixed to the lower surface of the base plate 401. The mounting wing plates 402 are provided with elongated mounting holes 402a.
[0026] The side panel of the enclosure 1 is provided with a heat dissipation structure for ventilation of the internal components. The interior of the enclosure 1 is provided with multiple layers of spaced support plates 5, and electrical components are mounted on the support plates 5.
[0027] It should be noted that one of the core innovations of this utility model lies in the structural design of the mounting base 4. This base consists of a horizontal base plate 401 and a vertically extending mounting wing plate 402, forming a stable and highly rigid support frame. This design cleverly transfers the installation force point from the bottom of the housing 1 to the stronger wing plate, optimizing the mechanical structure. The elongated mounting holes 402a on the mounting wing plate 402 provide crucial positional adjustment margins for the housing in at least one direction (usually the length direction) in the horizontal plane. When unavoidable deviations occur in the positions of the pre-embedded bolts at the construction site, installers do not need to perform destructive on-site hole enlargement or foundation adjustment; they only need to loosen the nuts to allow the housing to be slightly moved within the elongated hole range until all bolts are properly aligned. This not only achieves rapid, non-destructive, and precise alignment installation, effectively compensating for foundation construction errors, but also improves installation efficiency and reduces labor costs and skill requirements.
[0028] Meanwhile, this utility model improves the overall performance of the chassis through the rational layout of the internal multi-layer mounting plates and the organic combination of the side plate's efficient heat dissipation structure. The multi-layer mounting plates provide a modular, high-capacity mounting platform for various electrical components (such as circuit boards, relays, terminal blocks, etc.), resulting in neat internal wiring, high space utilization, and easy maintenance, repair, and component replacement. The heat dissipation structure design effectively dissipates the heat generated during equipment operation, preventing performance degradation or component damage due to overheating, thus ensuring long-term, stable, and reliable operation of the equipment in various harsh environments along railway lines.
[0029] In this embodiment: the mounting base 4 is integrally formed from a metal sheet through a bending process, and there are two mounting wing plates 402, which are located on both sides of the mounting base 4 along the length direction.
[0030] It should be noted that the mounting base 4 is manufactured using sheet metal and a bending process to form a single piece. This process ensures a seamless connection between the base plate 401 and the two mounting flanges 402, creating a unified structure with high integrity and structural strength. This avoids problems such as deformation, stress concentration, or strength weakening that may occur with welding, making the base more resistant to vibration and impact in the railway environment. The two mounting flanges 402 are positioned on opposite sides of the base along its length. This symmetrical layout is most suitable when combined with the common strip foundations or double-bolt pre-embedded methods found along tracks. It provides balanced and stable support for the chassis and makes adjustments along its length smoother and more effective.
[0031] In this embodiment: the length direction of the elongated mounting hole 402a is consistent with the length direction of the mounting base 4, and there are no fewer than two elongated mounting holes 402a on the same mounting wing plate 402, and the mounting holes 402a on the two mounting wing plates 402 are positioned opposite each other.
[0032] It should be noted that the elongated mounting holes 402a are aligned with the length of the mounting base 4. This design directly addresses the common longitudinal deviation problem of pre-embedded bolts in the trackside foundation. Each mounting wing plate 402 has at least two elongated holes, precisely corresponding to the holes on the opposite mounting wing plate 402, thus forming multi-point positioning. This design not only retains the freedom of adjustment in one direction, but more importantly, it prevents the chassis from rotating around the vertical axis after fixing, ensuring the accuracy of the installation orientation and overall stability. The multiple mounting holes 402a also distribute the force on the fixing points, improving the reliability of the connection under vibration.
[0033] In this embodiment: a locking member 6 is provided on the base plate 401, and a threaded hole 7 that cooperates with the locking member 6 is provided at the bottom of the housing 1. The mounting base 4 is detachably connected to the housing 1 through the cooperation of the locking member 6 and the threaded hole 7.
[0034] It should be noted that a detachable connection between the mounting base 4 and the housing 1 is achieved by setting locking components 6 (such as bolts) on the base plate 401 and pre-drilling matching threaded holes 7 at the bottom of the housing 1. This connection method has significant practical value, facilitating transportation by allowing the bulky housing and base to be moved separately, reducing difficulty and cost. During maintenance, if the base is damaged due to accidental impact or needs replacement, it can be quickly removed from the intact housing 1, achieving modular replacement and saving maintenance time and costs. In addition, this design also brings flexibility to production; the same housing 1 can be adapted to mounting bases 4 of different specifications to meet diverse on-site installation needs.
[0035] In this embodiment: the heat dissipation structure is in the form of a louver 8, and the inner side of the louver 8 is provided with a vertical waterproof and breathable membrane 9.
[0036] It should be noted that the louvered cooling structure (8-type) effectively blocks most rain, snow, and splashing water from directly entering the enclosure while ensuring sufficient ventilation cross-sectional area, achieving basic-level protection. A vertically installed waterproof and breathable membrane (9) is added to the inside. This membrane allows air circulation and water vapor permeation, balancing pressure and aiding heat dissipation, while completely blocking liquid water intrusion, thus improving the enclosure's waterproof rating. The vertical orientation also facilitates the rapid flow of any small amount of moisture adhering to the membrane, preventing accumulation and ensuring the long-term effectiveness of its breathability.
[0037] Specifically, the waterproof and breathable membrane 9 is tightly pressed onto the inner frame of the louver 8 by a pressure frame and a sealing ring, ensuring the sealing of its perimeter and facilitating future replacement.
[0038] In this embodiment: the inner wall of the box 1 is attached with an electromagnetic shielding pad 10, which is a conductive rubber or metal spring.
[0039] It should be noted that attaching electromagnetic shielding gaskets 10 to the inner wall of enclosure 1 is an important protective measure against the complex electromagnetic environment of railway sites (such as traction power supply and high-power radio waves). When enclosure door 2 is closed, these gaskets form a continuous conductive path at the joints of enclosure 1, constructing a complete Faraday cage. Whether using elastic and environmentally sealing conductive rubber or durable and highly shielding metal springs, the core purpose is to effectively attenuate external electromagnetic interference while suppressing internal signal leakage, thereby ensuring that the sensitive trackside signaling equipment inside the enclosure is not interfered with and operates stably and reliably.
[0040] In this embodiment: a sealing strip 11 is provided on the inner periphery of the door 2, and a guide plate 12 is provided on the top plate of the box body 1. The vertical cross-section of the guide plate 12 is inverted V-shaped.
[0041] It should be noted that the sealing strip 11 installed on the inner periphery of the enclosure door 2 fits tightly against the door frame of the enclosure 1, forming the first line of defense and effectively preventing dust, moisture, insects, and other contaminants from entering the enclosure. The inverted V-shaped (herringbone) deflector 12 on the top plate of the enclosure 1 is an active protective design. Its function is to quickly divert rainwater or melting snow falling on the top of the enclosure to both sides during rainy or snowy weather, preventing water accumulation and minimizing the chance of rainwater directly washing over the enclosure door 2 and door seams. These two measures work together to form a double seal and physical protection for the internal environment of the enclosure 1, improving the enclosure's protection level and environmental adaptability.
[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
