Description

Technical Field

[0001] This utility model relates to the field of rail transit, specifically to a novel sleeper structure compatible with the deployment of miniaturized equipment. Background Technology

[0002] In the railway safety assurance system, miniaturized intelligent monitoring equipment (hereinafter referred to as miniaturized equipment) plays a crucial role, such as the THDS (Head-to-Side Temperature Detection System) for vehicle axle temperature, the TFDS (Trackside Image Detection System) for freight car faults, the TADS (Trackside Acoustic Diagnostic System) for rolling bearing faults in railway vehicles, the TPDS (Trackside Dynamic Monitoring System) for railway vehicle operation quality, and the TCDS (Train Car Operation Safety Monitoring System). With the continuous advancement of railway freight speed-up, maintenance schedule reform, and the popularization of the "track window" maintenance system, the contradiction between the daily maintenance of miniaturized equipment and on-site construction is intensifying: Currently, most miniaturized equipment is mounted outside the track, occupying extra space, requiring disassembly during track maintenance. Frequent disassembly and assembly not only consumes manpower and resources but also brings higher operational risks and operating costs. Taking THDS equipment as an example: currently, when THDS equipment is used in conjunction with large machinery, the trackside portion requires multiple manual disassembly and assembly; according to statistics, of the more than 7,000 sets of THDS equipment deployed nationwide, each operation requires at least four people specifically for disassembly and assembly. Therefore, this existing operating method faces challenges in terms of efficiency, safety, and cost control. At the same time, many of the newly built lines are located in areas with complex geology, restricted access, or harsh climate, which places higher demands on the rapid deployment and long-term reliability of miniaturized equipment.

[0003] The trend of intelligent monitoring equipment for rail transit towards miniaturization and high integration is becoming increasingly clear, which brings about new adaptation requirements for sleeper structures. Traditional concrete sleepers only meet the requirements of rail bearing and stress, without considering the integration requirements such as ease of operation and maintenance, making it difficult to match the comprehensive technical requirements of the new generation of miniaturized intelligent equipment in terms of on-site installation, long-term operation, and maintenance-free operation. Utility Model Content

[0004] This utility model provides a novel sleeper structure that is compatible with the deployment of miniaturized equipment, in order to solve the contradiction between miniaturized equipment and on-site operation and maintenance in the prior art, and to achieve the goal of performing track maintenance work without disassembling the miniaturized equipment.

[0005] This utility model is achieved through the following technical solution:

[0006] A novel sleeper structure compatible with miniaturized equipment deployment includes a sleeper body, two rail support platforms located on the sleeper body, and a wiring channel located inside the sleeper body; the top surface of the sleeper body is provided with several installation areas for installing miniaturized equipment, each installation area including branch channels opened from the top surface of the sleeper body, the branch channels communicating with the wiring channel.

[0007] The existing technology presents a conflict between miniaturized equipment and on-site maintenance, primarily manifested in the external mounting of miniaturized equipment on sleepers and the need to disassemble the miniaturized equipment during track maintenance to avoid interfering with the operation of the maintenance equipment. To overcome these problems, this invention proposes a novel sleeper structure compatible with the deployment of miniaturized equipment. The sleeper body and rail support platform are existing sleeper structures that are easily understood by those skilled in the art. This application includes a wiring channel inside the sleeper body; furthermore, an installation area is provided on the top surface of the sleeper body for mounting the miniaturized equipment, which is connected to the wiring channel via a branch channel, thus providing dedicated space for laying the wiring (such as data cables, power cables, etc.) of the miniaturized equipment.

[0008] In practical use, this application involves installing the miniaturized equipment in the corresponding installation area according to the specific equipment type and operational needs, and routing the miniaturized equipment through wiring channels and branch channels. Compared with the existing technology of externally mounted miniaturized equipment, this application integrates the miniaturized equipment onto the sleeper body, so that the miniaturized equipment and the sleeper body are distributed vertically. This allows for the completion of tamping, curing, and other maintenance operations without disassembling the miniaturized equipment, while maintaining the original mechanical properties of the sleeper. This significantly improves operational efficiency, reduces manpower consumption, effectively reduces on-site wiring interference and subsequent maintenance obstacles, and improves the stable operation and service life of the miniaturized equipment under various working conditions.

[0009] The promotion and application of the new sleeper structure in this application will not only significantly improve the deployment efficiency and reliability of various miniaturized equipment in the railway transportation system, but also reduce construction coordination costs, improve operation and maintenance efficiency and the overall benefits of railway transportation, provide basic support for smart railways and intelligent equipment, and promote the railway infrastructure to move towards higher-quality development.

[0010] Those skilled in the art will understand that the miniaturized equipment described in this application includes, but is not limited to, vehicle axle temperature detection system THDS, freight car fault trackside image detection system TFDS, railway vehicle rolling bearing fault trackside acoustic diagnostic system TADS, railway vehicle operation quality trackside dynamic monitoring system TPDS, and passenger car operation safety monitoring system TCDS.

[0011] Furthermore, the height difference between the top of the rail support platform and the top surface of the sleeper body is 50~80mm.

[0012] In existing technologies, the height difference between the rail support platform and the sleeper body is generally 20-40mm. This solution increases the height of the rail support platform and the height difference between the rail support platform and the sleeper body, thereby providing more structural space for the installation of miniaturized equipment and making it more conducive to meeting the integration requirements of miniaturized equipment on the sleeper body.

[0013] Furthermore, the installation area also includes several pre-embedded mounting components, which are used to connect to miniaturized equipment.

[0014] This solution pre-embeds several mounting components within the installation area, defining them as pre-embedded mounting components. These pre-embedded mounting components are embedded inside the sleeper body and should be compatible with the miniaturized equipment to be installed. This facilitates the rapid and efficient installation of the corresponding miniaturized equipment, ensuring reliable fixation and improving the convenience and accuracy of the installation operation. The pre-embedded mounting components in this solution include, but are not limited to, nuts, bolt holes, and other pre-embedded parts that enable effective fixed connection to the miniaturized equipment.

[0015] Furthermore, the installation area is set in the direction away from the other rail platform on either rail support platform. This design allows for the installation of miniaturized equipment, such as axle temperature detection boxes, trackside acoustic detection units, data acquisition boxes, and laser sensors, on both sides of the sleeper as needed, even with installation areas on both sides of the rail support platform on their respective outer sides.

[0016] Furthermore, one or two installation areas are set between the two rail support platforms to facilitate the installation of miniaturized equipment, such as vehicle number recognition devices and infrared sensors, in the middle of the sleepers as needed, according to actual requirements.

[0017] Furthermore, the wiring channel extends through the sleeper body along its length, which is more conducive to the wiring operation of various miniaturized devices.

[0018] Furthermore, the open ends of the wiring channels and branch channels are all equipped with detachable end caps. When wiring is not required or operation is not needed, this solution can seal the corresponding wiring channels and branch channels using the end caps.

[0019] Furthermore, several reinforcing steel bars are arranged inside the rail support platform. This effectively improves the local load-bearing capacity of the rail support platform and significantly reduces the risk of damage to the sleepers caused by common external impacts during manufacturing and subsequent maintenance.

[0020] Furthermore, several prestressed steel wires are arranged inside the sleeper body. This solution fully considers the strength and durability requirements of various railway lines, such as heavy-haul, high-speed, and mixed passenger and freight lines. By arranging prestressed steel wires inside the sleeper body, the load-bearing system design is optimized to ensure the mechanical performance and structural stability of the sleeper during long-term operation, and it is suitable for the long-term service needs of various railway lines, such as heavy-haul, high-speed, and mixed passenger and freight lines.

[0021] Furthermore, the wiring channels and branch channels are made of metal pipes and / or plastic pipes; independent wiring channels can be easily and conveniently formed using metal or plastic pipes, adapting to the data and power cable laying requirements of different types of miniaturized devices. The metal or plastic pipes in this solution can have any cross-sectional shape.

Therefore, they should not be construed as limiting the scope of protection of this application.

[0036] Existing sleeper structures lack systematic consideration for the integration and installation of miniaturized equipment (such as the vehicle axle temperature detection system THDS, freight car fault trackside image detection system TFDS, railway vehicle rolling bearing fault trackside acoustic diagnostic system TADS, railway vehicle operation quality trackside dynamic monitoring system TPDS, passenger car operation safety monitoring system TCDS, etc.), resulting in the following prominent problems: 1. Difficulty in balancing load-bearing capacity: Partially modified sleeper structures may weaken load-bearing capacity or alter dynamic response characteristics, making long-term stable use on the main line track difficult and posing significant safety hazards; 2. Difficulty in equipment wiring and poor protection performance: Traditional sleepers cannot have built-in cable conduits, requiring additional trenches or exposed wiring, which not only complicates construction and is susceptible to environmental interference, but also results in poor equipment operation stability and overall system reliability, easily affecting train operation safety and daily maintenance work; 3. Difficulty in equipment installation and structural incompatibility: Existing sleepers do not reserve space for equipment installation, requiring additional accessories or external brackets for installation, which not only increases construction difficulty and time costs, but also affects the structural strength of the sleeper itself and the efficiency of subsequent maintenance work. The novel sleeper structure provided in this embodiment is used to overcome the above-mentioned technical problems.

[0037] Example 1:

[0038] A novel sleeper structure compatible with miniaturized equipment deployment, such as Figure 1 and Figure 2 As shown, the device includes a sleeper body 1 and two rail support platforms 2 located on the sleeper body 1. The rail support platforms 2 are provided with fastener pre-drilled holes 8 for installing fasteners. It also includes a wiring channel 3 located inside the sleeper body 1. The top surface of the sleeper body 1 is provided with several installation areas for installing miniaturized equipment. The installation area includes branch channels 4 opened from the top surface of the sleeper body 1 and several pre-embedded installation parts 5 located around the branch channels 4. The branch channels 4 are connected to the wiring channel 3, and the pre-embedded installation parts 5 are used to connect to the miniaturized equipment.

[0039] In this embodiment, the height difference between the top of the rail support platform 2 and the top surface of the sleeper body 1 is 50~80mm.

[0040] In this embodiment, a number of reinforcing steel bars 6 are arranged inside the rail support platform 2; preferably, the reinforcing steel bars 6 are arranged in a crisscross pattern.

[0041] In this embodiment, 8-16 prestressed steel wires 7 are arranged inside the sleeper body 1, and the ultimate tensile strength of a single prestressed steel wire 7 is 1670 N / mm². 2 The prestressed steel wire 7 must be laid out in a way that avoids the embedded installation part 5 and the wiring channel 3 and branch channel 4.

[0042] Preferably, the prestressed steel wire is a 7mm thick low-relaxation spiral rib steel wire. Its placement needs to be combined with the equipment hole avoidance design, and its tensile standard value, tensile design value, axial compressive design value, and the plasticity influence coefficient of concrete in the tension zone are all selected according to relevant specifications and technical requirements.

[0043] When used on-site, this embodiment ensures that the total width of the sleeper body and the various miniaturized devices installed on it is less than the working distance between adjacent tamping picks of the tamping machine, so as to meet the requirement of no disassembly throughout the entire engineering operation and significantly improve construction efficiency and equipment service life.

[0044] Example 2:

[0045] A novel sleeper structure compatible with miniaturized equipment deployment, based on Embodiment 1, has two symmetrically distributed installation areas between two rail support platforms 2; in addition, this embodiment also sets installation areas on the outer sides of both rail support platforms 2.

[0046] In this embodiment, the wiring channel 3 and branch channel 4 are metal or plastic pipes, preferably stainless steel pipes with a wall thickness of 3-5mm. The wiring channel 3 runs along the length of the sleeper and is specifically designed for wiring and cable protection of miniaturized equipment. This design significantly improves wiring efficiency and protection level, avoids the vulnerability of traditional exposed wiring, can withstand greater internal uniform pressure, and is less prone to damage or leakage, thus meeting on-site usage requirements.

[0047] In this embodiment, the open ends of the wiring channel 3 and the branch channel 4 are all equipped with detachable end caps to ensure that the wiring area of ​​the equipment has waterproof, dustproof and corrosion-resistant capabilities, meeting the requirements for long-term outdoor operation.

[0048] In a more preferred embodiment, the end cap may be provided with a wire hole, which facilitates both wire routing and sealing.

[0049] In a more preferred embodiment, the end cap is made of polymer composite material or metal material and is connected by bolt sealing.

[0050] In a more preferred embodiment, the shape and size of the metal or plastic pipe can be flexibly selected according to the equipment wiring requirements, such as using an elliptical pipe with a cross-sectional size of 40mm×50mm.
