Description

Technical Field

[0001] This invention belongs to the field of intelligent operation and maintenance and condition monitoring technology of rail transit signaling equipment, specifically involving a key component monitoring device for a ZYJ7 type switch machine. Background Technology

[0002] The ZYJ7 switch machine is a core execution device in railway and urban rail transit signaling systems. It utilizes internal locking and switching mechanisms and contact components to enable accurate switching and reliable locking of turnouts, ensuring safe train operation. As railways and urban rail transit develop towards higher density and higher speed, the requirements for the operational stability of key components of the ZYJ7 switch machine are constantly increasing, making the monitoring need to promptly detect component abnormalities and avoid failure risks increasingly urgent.

[0003] Existing monitoring of key components of the ZYJ7 switch machine mostly uses ordinary contact sensors, which are cumbersome to install and have poor adaptability. They are difficult to fit into the assembly space of the switch machine and can easily affect the original protection of the equipment and manual observation. To improve the adaptability and practicality of the monitoring device for key components of the ZYJ7 switch machine, how to develop a modular monitoring structure that can adapt to the three-dimensional assembly space of the switch machine, and achieve rapid assembly of monitoring components, simultaneous monitoring of multiple key components, and reliable sealing protection without borrowing the original screws of the switch machine, changing its original IP protection requirements, or obstructing the manual observation view, is a technical challenge faced by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a key component monitoring device for the ZYJ7 switch machine.

[0005] The technical solution of the present invention is as follows: A key component monitoring device for a ZYJ7 switch machine includes the ZYJ7 switch machine and an overall monitoring assembly. The ZYJ7 switch machine is composed of a top cover and a bottom shell. The assembly gap formed by the top cover and the bottom shell serves as the installation base. The overall monitoring assembly is installed within this assembly gap using a combination of physical limiting and snap-locking. The snap-locks do not use the original screws of the ZYJ7 switch machine, and their position and quantity can be set as needed. The overall monitoring assembly is composed of a modular structure, including a safety switch contact monitoring module, a dynamic and static contact monitoring module, a fixed support module, a sealing module, a wiring harness module, a limiting module, a locking block, and a crank shaft monitoring module, and is adapted to the three-dimensional assembly space of the top cover.

[0006] According to a preferred embodiment, the fixed support module is a rectangular frame with a large hollow structure. The frame skeleton and hollow position of the fixed support module can be adjusted according to the switch machine model and monitoring requirements without affecting daily maintenance and manual observation. The safety switch contact monitoring module, the dynamic and static contact monitoring module, and the lock block and crank shaft monitoring module can be assembled in the fixed support module according to different monitoring requirements.

[0007] According to a preferred embodiment, the locking block and crank shaft monitoring module is used to monitor the amount of locking block ejection after the ZYJ7 type switch machine overturns, and is adapted to crank shaft status monitoring; the dynamic and static contact monitoring module is used to monitor the driving depth of the dynamic contact after overturning, and the long-term movement status and movement amount of the static contact; the safety switch contact monitoring module is used to continuously track the safety switch opening and closing process and the contact movement amount during long-term operation.

[0008] According to a preferred embodiment, the sealing module is arranged around the bottom edge of the fixed support module. The sealing module is a single-sided sealing strip, and after the cover is closed, all pairs of sealing surfaces form a metal-rubber fit, without changing the original IP protection requirements of the ZYJ7 switch machine.

[0009] According to a preferred embodiment, the limiting module is located at the bottom of the fixed support module, one end of the limiting module is connected to the fixed support module, and the other end of the limiting module abuts against the inner wall of the bottom shell.

[0010] According to a preferred embodiment, the installation position of the limiting module can be set according to different needs, and it has the dual functions of guiding the overall monitoring component during installation and limiting it after installation.

[0011] According to a preferred embodiment, the wiring harness module adopts a customized spatial arrangement, and the wiring path of the wiring harness module is arranged at a right angle along the turning edge of the fixed support module, avoiding the key moving parts inside the ZYJ7 type switch machine.

[0012] According to a preferred embodiment, the wiring harnesses of the lock block, the crank shaft monitoring module, the dynamic and static contact monitoring module, and the safety switch contact monitoring module are converged and only one quick connector is reserved, and the wiring path does not increase the obstruction space for manual observation of the switch machine.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes the assembly gap and physical limiting combined with the buckle locking installation method of the ZYJ7 type switch machine's upper cover and bottom shell. Since the buckle does not use the original screws of the switch machine and can be set as needed, and the overall monitoring component is a modular structure that adapts to the three-dimensional space of the upper cover, it can meet the monitoring and installation requirements of key components of the ZYJ7 type switch machine, improve the adaptability and ease of installation of the device, and does not damage the original components of the switch machine or interfere with its normal operation.

[0014] Secondly, the device can achieve multi-dimensional targeted monitoring of switch machine lock blocks, crankshafts, dynamic and static contacts, and safety switches through the fixed support module's large rectangular frame and hollow structure, and the on-demand assembly of various monitoring modules. This allows the device to adapt to different monitoring needs without obstructing manual observation. Then, through the sealing of the single-sided sealing strip of the sealing module, the guiding and limiting function of the limiting module, and the right-angle wiring path of the customized wiring harness, the device can achieve reliable protection, stable installation, and stable signal transmission, improving the device's monitoring comprehensiveness, protection reliability, and practicality.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but should not be used to limit the scope of protection of the present invention.

[0018] Example: For example Figures 1 to 4As shown, this invention provides a key component monitoring device for a ZYJ7 switch machine, comprising a ZYJ7 switch machine and an integrated monitoring assembly 11. The ZYJ7 switch machine serves as the basic support carrier of the device, and its overall structure consists of the original upper cover 12 and bottom shell 13. When the two are joined together, they naturally form a uniform and regular assembly gap. This assembly gap does not require any modification such as drilling, welding, or cutting, and directly serves as the dedicated installation space for the integrated monitoring assembly 11. This approach maximizes the preservation of the structural integrity and operational stability of the original ZYJ7 switch machine shell while making full use of the existing space. It ensures that the integrated monitoring assembly 11 does not occupy any extra space inside the switch machine or interfere with the normal operation of the key internal components after installation, thus providing a fundamental guarantee for the stable operation of the device. The integrated monitoring assembly 11, as the core functional carrier of the device, employs a combination of physical limiting and snap-fit ​​mechanisms. The locking mechanism secures the components within the assembly gap. The location and number of the clips can be set according to the internal space layout and fixing requirements of the switch machine. The entire process does not require the use of the original screws of the ZYJ7 switch machine, nor any additional installation tools. The installation is convenient and detachable, facilitating future operation, maintenance, module replacement, and the maintenance of the switch machine itself. It also ensures that the components are firmly installed and do not loosen under continuous vibration of the railway track. The overall monitoring component 11 adopts a modular assembly structure, consisting of a safety switch contact monitoring module 14, a dynamic and static contact monitoring module 15, a fixed support module 16, a sealing module 17, a wiring harness module 18, a limit module 19, and a locking block and crank shaft monitoring module 21. Each module is independently formed and can be assembled and disassembled. The overall structure is compatible with the three-dimensional assembly space of the top cover 12 and is compatible with the original components of the switch machine without interference.

[0019] The fixed support module 16 serves as the fundamental load-bearing core of the overall monitoring assembly 11. It employs a structure combining a large rectangular frame with large openwork sections. The frame skeleton is made of high-strength, lightweight material, possessing both excellent structural rigidity and lightweight characteristics. It can stably support the weight of each monitoring module and wiring harness module 18, while also being adaptable to the continuous vibration conditions of railway tracks. It is not easily deformed or detached, maintaining structural stability over a long period. The orientation of the frame skeleton and the position of the openwork sections of the fixed support module 16 can be adjusted according to the specific model of the ZYJ7 switch machine, the distribution of key internal components, and actual monitoring requirements. The adjustment process does not require destructive processing of the module, adapting to the usage requirements of different specifications of the ZYJ7 switch machine. The large openwork structure not only reduces the weight of the overall monitoring assembly... The weight of component 11 avoids additional load on the fastening structure of the switch machine's top cover 12 and bottom shell 13, while ensuring that it does not obstruct key internal components of the switch machine and does not affect the daily maintenance operations and manual observation of maintenance personnel. This facilitates routine inspections and troubleshooting of the switch machine's interior by maintenance personnel. The fixed support module 16 has multiple pre-set standardized mounting positions. The safety switch contact monitoring module 14, the dynamic and static contact monitoring module 15, and the lock block and crank shaft monitoring module 21 can be assembled into the corresponding pre-set mounting positions according to different monitoring needs. The assembly process does not require additional drilling or fixing, and can be quickly completed for installation and disassembly. This not only adapts to the monitoring needs in different scenarios but also reduces the cost of later module maintenance and replacement, improving the versatility and convenience of the device.

[0020] The locking block and crank shaft monitoring module 21, the dynamic and static contact monitoring module 15, and the safety switch contact monitoring module 14 are the core data acquisition components of the device. These three modules work independently yet collaboratively, comprehensively covering the key operating components and core actions of the ZYJ7 switch machine. This enables full-dimensional, all-time monitoring of the operating status of key switch machine components. The data acquisition process is non-contact, avoiding any contact with existing switch machine components and ensuring uninterrupted operation. The locking block and crank shaft monitoring module 21 is installed at the corresponding preset position on the fixed support module 16. After installation, it accurately aligns with the locking block and crank shaft positions. Its core function is to monitor the real-time ejection amount of the locking block after overshooting the ZYJ7 switch machine, recording key data such as the ejection distance and speed, and determining whether the locking block ejection is complete, whether there is jamming, or abnormal ejection amount. Simultaneously, it is adapted for crank shaft status monitoring, capturing real-time data such as the crank shaft's operating posture and rotation angle, promptly detecting abnormalities such as crank shaft wear, offset, and jamming, thus providing a basis for the switch machine's operation. The reliability of the switch machine's locking and transmission functions is supported by data. The dynamic and static contact monitoring module 15 is installed at the corresponding mounting position of the fixed support module 16, aligned with the connection between the dynamic and static contacts of the switch machine. It is used to monitor the driving depth of the dynamic contact after the switch machine overturns in real time, determine whether the dynamic contact is driven in place and whether the contact is good, and continuously track the movement status and amount of the static contact during long-term operation. It identifies abnormalities such as static contact offset, wear, and poor contact, and avoids signal transmission failure of the switch machine due to contact problems, thus ensuring the stability of the switch machine's signal transmission. The safety switch contact monitoring module 14 is adapted to the mounting position layout of the fixed support module 16 and aligned with the position of the switch machine's safety switch. It is used to continuously track the opening and closing process of the safety switch cover, record the action time, speed, and other data of the cover, and monitor the amount of contact movement of the safety switch during long-term operation. It can promptly detect safety hazards such as safety switch jamming, contact offset, and abnormal action, ensuring that the safety protection function of the switch machine functions normally and avoiding safety accidents. All three monitoring modules can be selected and disassembled according to the actual monitoring needs on site, without the need to replace the entire monitoring component 11, thus reducing operation and maintenance costs. Furthermore, the acquisition accuracy and acquisition frequency can be adjusted according to the on-site operation and maintenance needs, adapting to different operating conditions of the ZYJ7 switch machine.

[0021] The sealing module 17 is the core of the device's protection. It employs a single-sided sealing strip structure and is made of aging-resistant, vibration-resistant, waterproof, and dustproof rubber material, adapting to the sealing requirements of the ZYJ7 switch machine. Its structure does not alter the original IP protection requirements of the ZYJ7 switch machine, ensuring that the original sealing performance of the switch machine remains unaffected and can continuously resist the erosion of harsh outdoor environments. The sealing module 17 is arranged in a ring around the bottom edge of the fixed support module 16, fitting tightly and without gaps to ensure the integrity of the seal. When the switch machine's upper cover 12 and bottom shell 13 are closed, the switch machine... All pairs of sealing surfaces between the metal housing (upper cover 12, lower cover 13) and the overall monitoring component 11 form a tight fit between the metal surface and the rubber surface, constructing a complete and reliable sealing barrier. This sealing barrier can prevent dust, water vapor, rainwater, oil and other impurities in the outdoor environment from entering the switch machine. It not only protects the original key components of the switch machine from the corrosion of impurities and extends their service life, but also prevents impurities from entering the monitoring modules and wiring harness modules 18, avoiding monitoring module failures and wiring harness short circuits, ensuring the long-term stable operation of the overall monitoring component 11, and meeting the usage requirements of harsh outdoor working conditions in railways.

[0022] The limiting module 19 is fixedly installed at the bottom of the fixed support module 16. One end of the limiting module 19 is connected to the bottom frame of the fixed support module 16, with a firm and secure connection. The other end extends to the inner wall of the switch machine bottom shell 13. After the overall monitoring component 11 is installed in place, this end of the limiting module 19 abuts against the inner wall of the bottom shell 13, forming a rigid support. The installation position of the limiting module 19 can be set according to the inner wall structure of the switch machine bottom shell 13, the installation height of the fixed support module 16, and the actual fixing requirements, adapting to the installation requirements under different working conditions. It also serves the dual functions of guiding the installation of the overall monitoring component 11 and limiting its position after installation. During the installation of the overall monitoring component 11... The limiting module 19 can guide the component to be accurately and smoothly inserted into the assembly gap between the upper cover 12 and the bottom shell 13 from top to bottom, avoiding component misalignment or tilting, and preventing collision with key components such as locking blocks, crankshafts, and contacts inside the switch machine, which could cause damage to the components. After the overall monitoring component 11 is installed in place, the rigid support formed by the limiting module 19 and the inner wall of the bottom shell 13, together with the physical limiting and buckle locking, achieves multiple fixation of the overall monitoring component 11, ensuring that the component does not shift or shake under the action of external forces such as continuous track vibration and outdoor wind, ensuring that the acquisition position of each monitoring module is always accurate, and providing a reliable guarantee for the accuracy of monitoring data.

[0023] The wiring harness module 18 adopts a customized spatial configuration. Its wiring harness length and routing path are pre-defined based on the frame structure of the fixed support module 16, the installation positions of each monitoring module, and the distribution of key components inside the switch machine. No secondary adjustments are required on-site, ensuring the wiring harness is neat and fits the internal space of the switch machine, while avoiding interference with internal components. The routing path of the wiring harness module 18 is strictly arranged along the right-angle space of the turning edge of the fixed support module 16, adhering to the surface of the frame skeleton of the fixed support module 16, without any suspension or tangling. This avoids damage to the wiring harness caused by squeezing, pulling, or abrasion from key moving parts inside the switch machine, while also saving internal space and not increasing manpower for the switch machine. The obstructed observation space facilitates routine inspections and troubleshooting of the switch machine's interior by maintenance personnel. The acquisition harnesses of the lock block, crank shaft monitoring module 21, dynamic and static contact monitoring module 15, and safety switch contact monitoring module 14 are all neatly converged, ultimately reserving only one quick connector. This reduces wiring nodes, lowers interference during signal transmission, and improves the stability and reliability of data transmission. This quick connector is located on the outside of the overall monitoring component 11, away from critical internal components of the switch machine, facilitating quick connection with external monitoring systems without requiring complex wiring operations inside the switch machine. This improves installation and maintenance efficiency and avoids damage to internal components of the switch machine during wiring.

[0024] The specific usage and function of this embodiment are as follows: During use, the modular pre-assembly of the overall monitoring component 11 is completed first. Based on the ZYJ7 switch machine model, internal space, and monitoring requirements, the frame structure and openwork layout of the fixed support module 16 are adjusted. The limiting module 19 is fixed at the preset bottom position, and the sealing module 17 is arranged around the bottom edge of the fixed support module 16. Then, the locking block, crank shaft monitoring module 21, dynamic and static contact monitoring module 15, and safety switch contact monitoring module 14 are correspondingly snapped into the standardized installation positions of the fixed support module 16. The wiring harness module 18 is neatly arranged according to the right-angle space of the turning edge of the fixed support module 16. After converging the wiring harnesses of the three types of monitoring modules, a single quick connector is reserved to complete the component pre-assembly. During on-site installation, the switch machine cover 12 is opened, and the overall monitoring component 11 is installed from top to bottom. The component is smoothly inserted into the assembly gap between the upper cover 12 and the bottom shell 13, and is positioned by the guiding action of the limiting module 19 to avoid misalignment and collision with key moving parts such as internal locking blocks, crankshafts, and contacts. After the component is in place, it is locked by the physical limiting action of the adjustable buckle and the assembly gap. The end of the limiting module 19 abuts against the inner wall of the bottom shell 13 to form a rigid support. The original screws of the switch machine are not used throughout the process, and no additional tools are required to complete the fixation. Then, the quick connector on the outside of the overall monitoring component 11 is directly plugged into the external railway signal monitoring system to complete the power supply and signal transmission link connection in one go without the need for on-site wiring and debugging. After closing the upper cover 12 of the switch machine, the sealing module 17 forms a metal-rubber surface seal with the metal shell of the switch machine, and the device immediately enters the working state.

[0025] During the operation monitoring phase, the three types of monitoring modules work synchronously in a non-contact manner: the locking block and crank shaft monitoring module 21 collects the locking block ejection amount, crank shaft running posture and rotation angle in real time after the switch machine overturns; the moving and stationary contact monitoring module 15 continuously monitors the driving depth of the moving contact and tracks the long-term displacement status of the stationary contact; the safety switch contact monitoring module 14 records the switch cover action parameters and contact movement throughout the process. All collected data are stably transmitted to the external monitoring system via the wiring harness module 18. The system compares the data with preset thresholds to identify abnormalities and issues fault warnings.

[0026] During device maintenance or switch machine overhaul, the entire monitoring component 11 can be removed by simply unlocking the latches. Each modular component can be disassembled and replaced individually. When reassembling, the above installation steps can be repeated for quick reuse without changing the original structure and operating status of the switch machine.

[0027] This device is installed without modification during assembly gaps, preserving the original structural integrity, IP protection level, and core operating functions of the ZYJ7 switch machine. It also achieves seismic fixation through the limit module 19, adapting to the continuous vibration conditions of railway tracks. The sealing module 17 prevents outdoor dust and moisture intrusion, ensuring long-term stable operation of the device and the switch machine. The large open design of the fixed support module 16 does not obstruct the maintenance observation space and does not affect the daily inspection of the switch machine. Three types of monitoring modules enable full-dimensional monitoring of key components, allowing for early identification of potential problems such as jamming, offset, and wear, reducing the intensity of manual inspections. The wiring harness module 18 features customized wiring and a single quick-connect head, improving installation and docking efficiency. Overall, it achieves online real-time monitoring of key components of the ZYJ7 switch machine, enhancing the operational reliability of the switch machine and the safety assurance capabilities of railway traffic.

[0028] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
