Description

Technical Field

[0001] This utility model relates to the field of switch machine maintenance technology, specifically a visual high-definition contact wiping rod. Background Technology

[0002] As the core actuator for railway turnout switching, the internal contacts of the switch machine are crucial for signal command transmission. The cleanliness of these contact surfaces directly determines the stability and reliability of electrical signal transmission. During railway operation, switch machine contacts are in a closed, humid working environment, easily absorbing contaminants such as dust, oil, and metal oxides. If not cleaned promptly or thoroughly, this can lead to increased contact resistance, signal transmission delays or even interruptions, causing safety hazards such as abnormal turnout switching and signal misinterpretation, seriously threatening train operation safety. With the development of modern railways towards high speed and high density, higher demands are placed on the signal transmission reliability and equipment maintenance efficiency of switch machines. Traditional contact cleaning methods suffer from low efficiency and poor cleaning results, making it difficult to meet the ever-increasing demands of modern railway transportation. Utility Model Content

[0003] The purpose of this invention is to provide a visual high-definition contact wiping rod. By setting a wiping head, it can closely adhere to the contact surface to effectively remove impurities such as oxide film, dirt, and oil stains generated during long-term use. Equipped with a camera, it can promptly detect minor imperfections and areas that are not thoroughly cleaned on the contact surface, so as to adjust the cleaning operation in time. It can also provide detailed and accurate video data for subsequent equipment maintenance and troubleshooting, greatly improving work efficiency and accuracy.

[0004] To address the problems of existing technologies, this utility model provides a visual high-definition contact wiping stick, including a main body and a wiping head. The main body and the wiping head are detachably connected. A camera is provided at one end of the main body near the wiping head to capture the real-time position of the wiping head. An extension rod is provided at the center of the end of the main body near the wiping head. A connecting rod is connected to the side of the wiping head near the extension rod. A clip is provided between the extension rod and the connecting rod to fix the connecting rod to the extension rod.

[0005] Preferably, the wiping head is made of a wear-resistant, non-shedding material.

[0006] Preferably, the material of the wiping head is a rubber alloy material.

[0007] Preferably, the clip has a first snap-fit ​​hole for inserting an extension rod and a second snap-fit ​​hole for inserting a connecting rod, and the clip is made of an elastic material.

[0008] Preferably, the end of the extension rod is provided with a detachable LED light, and the main body also has a control circuit board for controlling the LED light and the camera. The control circuit board is electrically connected to the LED light and the camera through wires, and the control circuit board also has a wireless transmission module.

[0009] Preferably, the main body also has a storage battery inside, and the storage battery is electrically connected to the control circuit board via wires. The main body is also provided with a control switch for controlling the LED lights and the camera, and the other end of the main body is provided with a charging port for charging the storage battery.

[0010] Preferably, the connecting rod has bending adaptability, and can form a bending angle along any plane under the action of external force, and can maintain the bending state after the external force is removed.

[0011] Preferably, the connecting rod is composed of multiple nested hollow rods, with the inner diameter of each rod decreasing sequentially along the extension direction, and adjacent rods forming a sliding nested structure; under the action of external force, each rod can extend and retract independently along the axial direction to realize the length adjustment of the connecting rod, and each rod can maintain the adjusted state after adjustment.

[0012] The advantages of this utility model compared to the prior art are: This application includes a wiping abrasive head made of a rubber alloy material. Its material properties allow for a tight fit with the contact surface, effectively removing conductive impurities such as oxide films, dirt, and oil that accumulate on the contact surface during long-term use. This fundamentally ensures good conductivity and contact stability of the contacts. Simultaneously, the rubber alloy material combines elasticity and wear resistance, effectively preventing scratch damage to the contact surface caused by traditional hard abrasive heads while ensuring adaptability to cleaning pressure. It also overcomes the technical shortcomings of cotton abrasive heads, such as the tendency to leave fibers and incomplete cleaning, achieving the dual goals of effective cleaning and contact protection. To improve the precision of the cleaning operation, this application includes a camera to construct a visual cleaning operation system. Operators can receive real-time video feeds from the camera via their mobile devices, clearly monitoring the entire cleaning process of the contact points. This not only helps operators identify areas that are not thoroughly cleaned and quickly adjust the cleaning angle to ensure full coverage, but also records the entire cleaning process. The resulting video data can serve as a core component of subsequent equipment maintenance records, providing detailed and visualized data support for contact point status trend analysis and potential fault tracing, significantly improving the targeting and accuracy of equipment operation and maintenance. Furthermore, leveraging the visualization advantages of cameras, operators can use the magnification function of their mobile phone screens to accurately confirm the removal of minute contaminants until the cleanliness of the contact surface reaches the preset technical standard, thus stopping the operation. This forms a closed-loop cleaning process of "visual monitoring - precise cleaning - compliance verification." The wiping grinding head adopts a modular design, supporting individual replacement. Compared with the easily worn characteristics of traditional cotton grinding heads and the high wear rate of metal grinding heads, its rubber alloy material provides a longer service life, significantly reducing the frequency of consumable replacement and related procurement costs. At the same time, by efficiently removing conductive interference impurities from the contact surface, it reduces equipment short circuits, signal interruptions, and other faults caused by poor contact at the source, reducing the frequency of downtime for maintenance, manpower input, and spare parts consumption during operation and maintenance, further saving on the operation and maintenance costs throughout the entire equipment life cycle.

[0018] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-4 As shown, this utility model provides a visual high-definition contact wiping stick, including a main body 1 and a wiping head 2. The main body 1 and the wiping head 2 are detachably connected. The wiping head 2 directly contacts the surface of the contact to be cleaned, and efficiently removes conductive interference impurities such as oxide film, dirt, and oil through friction, ensuring good conductivity and contact stability of the contact. A camera 13 is provided at one end of the main body 1 near the wiping head 2, which can be used to capture the real-time position of the wiping head 2. The camera 13 captures the working position of the wiping head 2 and the cleaning status of the contact surface in real time, outputs high-definition video images and transmits them to terminal devices such as mobile phones; and accurately captures minor defects on the contact surface (such as micro scratches and residual contaminants) and the contact posture of the wiping head 2, providing operators with intuitive visual reference and ensuring that the cleaning operation is precise and controllable; and records the entire cleaning process, and the resulting video data can be used as visual data support for subsequent equipment maintenance and troubleshooting. An extension rod 11 is positioned at the center of one end of the main body 1 near the wiping head 2. A connecting rod 21 is connected to the side of the wiping head 2 near the extension rod 11. A locking device 3 is provided between the extension rod 11 and the connecting rod 21 to secure the connecting rod 21 to the extension rod 11. The locking device 3 enables the extension rod 11 and the connecting rod 21 to be detachably fixed. The locking structure ensures the firmness of the connection between the two, preventing the wiping head from loosening or falling off due to vibration or force during the cleaning process, and ensuring the stability of the cleaning operation.

[0020] The wiping head 2 is made of a wear-resistant, non-shedding material. The material of the wiping head 2 is a rubber alloy.

[0021] The wiping head 2 is made of a wear-resistant, non-shedding rubber alloy material. Its core function is to directly contact the surface of the contact point to be cleaned, and rely on the wear-resistant and frictional properties of the rubber alloy material to efficiently remove conductive interference impurities such as oxide film, dirt, and oil, ensuring good conductivity and contact stability of the contact point. Secondly, the material has both elasticity and wear resistance, which can adapt to the contour of the contact point surface to achieve a tight fit, while avoiding scratch damage to the contact point surface. The non-shedding property can prevent debris generated during the cleaning process from remaining on the contact point surface, avoiding secondary pollution or poor contact. Furthermore, the wiping head 2 can be disassembled and replaced individually, reducing consumable costs and adapting to the needs of long-term repeated use.

[0022] The internal part of the clip 3 has a first snap-fit ​​hole 31 for inserting the extension rod 11 and a second snap-fit ​​hole 32 for inserting the connecting rod 21. The clip 3 is made of elastic material.

[0023] The clip 3 is made of elastic material. Its main function is to utilize the deformation characteristics of the elastic material to generate radial clamping force after the extension rod 11 and the connecting rod 21 are inserted, so as to realize the detachable fixation of the two. This ensures the firmness of the connection and allows the elastic material to undergo reversible deformation under external force, which facilitates quick unlocking and separation and simplifies the replacement operation of the wiping grinding head 2. The end of the extension rod 11 is equipped with a detachable LED light 12. The main body 1 also contains a control circuit board 16 for controlling the LED light 12 and the camera 13. The control circuit board 16 is electrically connected to the LED light 12 and the camera 13 via wires. The control circuit board 16 also has a wireless transmission module. The main body 1 also contains a battery 17, which is electrically connected to the control circuit board 16 via wires. The main body 1 is also equipped with a control switch 14 for controlling the LED light 12 and the camera 13. The other end of the main body 1 is equipped with a charging port 15 for charging the battery 17.

[0024] LED light 12 provides directional light source for the shooting area of ​​camera 13. Especially in narrow and dimly lit contact installation environments, it can effectively improve the brightness of the contact surface, eliminate shadow interference, ensure that the video image captured by camera 13 is clear and distinguishable, and ensure the accuracy of identification of fine contaminants. Control circuit board 16, as the core control unit, receives command signals from control switch 14 and coordinates the starting and stopping of LED light 12, shooting and recording of camera 13, and other working states. It also processes the video data transmitted by camera 13 and realizes data interaction with mobile APP through the wireless transmission module integrated on it (including real-time transmission of video image, uploading of device status information and receiving control commands from mobile phone).

[0025] Example 1: The connecting rod 21 has bending adaptability, and can form a bending angle along any plane under the action of external force, and can maintain the bending state after the external force is removed.

[0026] The connecting rod 21 has bending adaptability. Under the action of external force, it can form the required bending angle along any plane. After the external force is removed, it can maintain the bending state. It can flexibly adapt to complex contact positions such as deep cavity corners, irregular arrangements, and concealed installations, adjust the contact posture of the wiping grinding head 2, ensure the tight fit between the wiping grinding head 2 and the contact surface, and solve the cleaning blind spots that are difficult to cover by conventional straight rod structures.

[0027] Example 2: The connecting rod 21 is composed of multiple nested hollow rods. The inner diameter of each rod decreases sequentially along the extension and retraction direction, and adjacent rods form a sliding nested structure. Under the action of external force, each rod can extend and retract independently along the axial direction to realize the length adjustment of the connecting rod 21, and each rod can maintain the adjusted state after adjustment.

[0028] The connecting rod 21 has axial telescopic adaptation characteristics. Under the action of external force, each section of the rod can slide independently along the axis to achieve length adjustment. After adjustment, it can maintain the length state. It can flexibly adapt to complex contact positions such as deep cavities of different depths and long-distance arrangements, adjust the working distance of the wiping grinding head 2, ensure the tight fit between the grinding head and the contact surface, and solve the limitation of the cleaning range that conventional fixed length structures cannot cover.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
