DETAILED DESCRIPTION

[0034] The embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0035] As shown in Figures 1 to 4 The present application provides a wheel set marking device, comprising:

[0036] The base 100 is provided with a long groove 102 along the length direction of the base 100;

[0037] The fixed support seat 104 is rotatably arranged at one end of the long groove 102;

[0038] The movable support seat 106 is rotatably arranged at the other end of the long groove 102, and the movable support seat 106 is adapted to act along the length direction of the long groove 102 through the adjusting assembly;

[0039] The dial 108 is detachably installed on the wheel set;

[0040] The fixed support seat 104 and the movable support seat 106 are used to support the tread of the wheel set, and the dial 108 is used to identify the index of the wheel set under the condition that the wheel set rotates relative to the fixed support seat 104 and the movable support seat 106.

[0041] According to the wheel set marking device provided by the present application, the stability of the fixed support seat 104 and the movable support seat 106 and the accuracy of the dial 108 can significantly improve the accuracy of the wheel set marking. This is crucial to ensure the accuracy of the wheel set during the maintenance or maintenance process. Since the movable support seat 106 can move on the long groove 102 through the adjusting assembly, the device can adapt to wheel sets of different sizes. This design increases the versatility and practicality of the device and reduces the use cost. The detachable design of the dial 108 allows users to easily install or remove it as needed, simplifying the operation steps. At the same time, the adjustment of the movable support seat 106 is relatively simple, and users can only adjust the position through the adjusting assembly. The use of the wheel set marking device of the present application can greatly shorten the time required for marking or positioning, thereby improving work efficiency. This is of great significance to the wheel set maintenance and maintenance work in the fields of railways, rail transit, etc.

[0042] Please continue to see Figures 1 to 4 The wheel set marking device provided by the present application is designed to achieve the function of accurately marking or positioning the wheel set, and is particularly suitable for wheel set maintenance and maintenance work in the fields of railways, rail transit, etc.

[0043] The base 100 serves as the foundation support structure for the entire device. Along its length, the base 100 is equipped with a long slot 102. This long slot 102 provides the mobile support seat 106 with the space to move, allowing it to adjust its position as needed to accommodate wheelsets of different sizes.

[0044] The fixed support seat 104 is rotatably positioned at one end of the long slot 102. It serves to stabilize and support one end of the wheelset, ensuring that the wheelset remains stable during rotation.

[0045] The mobile support seat 106 is also designed to be rotatable, but it is located at the other end of the long slot 102 and can move along the length of the long slot 102 through an adjustment assembly. This design allows the mobile support seat 106 to adjust to different wheelset sizes, ensuring uniform support for the wheelset.

[0046] The dial 108 is detachably installed on the wheelset. When the wheelset rotates relative to the fixed support seat 104 and the mobile support seat 106, the dial 108 can accurately identify the index of the wheelset, i.e., the angle or position of the wheelset rotation. This is crucial for operations such as wheelset marking or positioning.

[0047] According to an embodiment of the present application, the mobile support seat 106 includes:

[0048] The slider 110 is embedded in the long slot 102.

[0049] The adjustment rod 112 is rotatably connected to the base 100 and in transmission connection with the slider 110.

[0050] In an embodiment of the present application, the design of the mobile support seat 106 is further refined to better achieve its flexible movement and stable support function within the long slot 102. Specifically, the slider 110 is a key connecting component between the mobile support seat 106 and the long slot 102 of the base 100. It is embedded in the long slot 102 and can freely slide along the length of the long slot 102. The design of the slider 110 ensures the stability and accuracy of the mobile support seat 106 during movement, while preventing the mobile support seat 106 from shifting or shaking during movement.

[0051] The adjustment rod 112 is a component that is rotatably connected to the base 100 and establishes a transmission connection with the slider 110. This means that when the user rotates the adjustment rod 112, the adjustment rod 112 will push or pull the slider 110 to move within the long slot 102 through some transmission mechanism (such as gear transmission, screw transmission, etc.). This design allows the user to adjust the position of the mobile support seat 106 by simply rotating the adjustment rod 112, thereby accommodating wheelsets of different sizes.

[0052] Furthermore, the design of the adjustment lever 112 also takes into account the convenience of user operation. For example, the adjustment lever 112 can be designed to have sufficient length and appropriate grip so that the user can easily grasp and turn it. At the same time, the adjustment lever 112 can also be marked with scales or indication marks to help the user more accurately adjust the position of the movable support seat 106.

[0053] Through the transmission connection of the adjustment lever 112 and the slider 110, the user can more accurately control the position of the movable support seat 106. This is crucial for ensuring uniform support of the wheel pair and accurate marking. The embedded design of the slider 110 in the long slot 102 ensures the stability of the movable support seat 106 during movement. This can prevent the movable support seat 106 from shifting or shaking during movement, thereby improving the stability and reliability of the entire device. By simply turning the adjustment lever 112, the user can easily adjust the position of the movable support seat 106. This design greatly simplifies the operation steps and improves work efficiency.

[0054] According to an embodiment of the present application, one end of the adjustment lever 112 extending out of the base 100 is provided with a first handle 114.

[0055] In an embodiment of the present application, the first handle 114 is specially provided at one end of the adjustment lever 112 extending out of the base 100. This design aims to improve the convenience and comfort of user operation, while ensuring the accuracy and stability of the adjustment process.

[0056] The first handle 114 is designed to be ergonomically shaped and sized so that the user can easily grasp and turn it. This design reduces user fatigue during long operation and improves work efficiency.

[0057] The first handle 114 can be made of wear-resistant and slip-resistant materials and treated on the surface (such as anti-slip texture, soft coating, etc.) to increase the stability and comfort of holding.

[0058] In order to more intuitively guide the user operation, the first handle 114 is also marked with function identification or indication arrows. These marks can help the user more accurately understand the function and turning direction of the adjustment lever 112, thereby avoiding misoperation.

[0059] The design of the first handle 114 allows users to hold and turn the adjustment rod 112 more easily, simplifying the operation steps and improving work efficiency. The anti-slip material and specially treated surface design increase the stability of holding, reducing the possibility of slipping or misoperation during adjustment. The ergonomic shape and size design reduce the user's fatigue during long-term operation, making the operation more comfortable. The presence of functional markings or indicator arrows allows users to more intuitively understand the function and rotation direction of the adjustment rod 112, improving the accuracy and reliability of the operation.

[0060] According to an embodiment of the present application, one end of the adjustment rod 112 extending out of the base 100 is provided with a locking member 116, and the adjustment rod 112 is adapted to be locked with the base 100 by the locking member 116.

[0061] In an embodiment of the present application, the adjustment rod 112 extending out of the base 100 is specially provided with a locking member 116. This design aims to ensure that the adjustment rod 112 can be stably locked on the base 100 after adjustment, preventing accidental movement or loosening during use, thereby ensuring the accuracy and reliability of the wheelset marking device.

[0062] The locking member 116 can adopt various locking methods, such as threaded locking, buckle locking, bolt locking, etc. These locking methods can effectively fix the adjustment rod 112 on the base 100, preventing it from moving.

[0063] The design of the locking member 116 should facilitate user operation. For example, the locking bolt can be equipped with a handle or knob that is easy to hold, so that the user can easily tighten or loosen the locking member 116.

[0064] The locking member 116 should be able to provide sufficient locking force to ensure the stability of the adjustment rod 112 on the base 100. At the same time, the locking force should not be too large, so as not to damage the threaded components of the adjustment rod 112 or the base 100.

[0065] The locking member 116 can ensure that the adjustment rod 112 is stably locked on the base 100 after adjustment, preventing accidental movement or loosening during use. This helps to improve the accuracy and reliability of the wheelset marking device. The design of the locking member 116 can prevent safety accidents caused by loosening or falling of the adjustment rod 112 during use. This is crucial for the safety of the operator. The design of the locking member 116 should facilitate user maintenance and replacement. For example, when the locking member 116 is damaged or worn out, the user can easily remove and replace it with a new locking member 116. By choosing appropriate locking methods and materials, the locking member 116 can ensure sufficient durability, thereby prolonging the service life of the wheelset marking device.

[0066] According to one embodiment of the present application, along the length direction of the long groove 102, an opening groove 118 is opened at the position corresponding to the groove side wall of the long groove 102 and the sliding block 110. The opening groove 118 is provided with a stop block 120 shielding the opening groove 118, and the sliding block 110 is adapted to be limited from being pulled out of the opening groove 118 by the stop block 120.

[0067] In one embodiment of the present application, the opening groove 118 is opened on the groove side wall along the length direction of the long groove 102, and its position and size are accurately calculated to ensure that the sliding block 110 can smoothly enter and cooperate with the opening groove 118 during sliding, while not affecting the normal sliding of the sliding block 110.

[0068] The stop block 120 is arranged in the opening groove 118, partially shielding the opening groove 118, forming an effective blocking structure. The material, shape and size of the stop block 120 are carefully selected and designed to ensure that it can be firmly fixed in the opening groove 118 and can provide sufficient resistance when the sliding block 110 slides to prevent the sliding block 110 from accidentally falling out.

[0069] During the sliding process of the sliding block 110, a part of it will enter the opening groove 118 and contact the stop block 120. When the sliding block 110 is subjected to external force or vibration, the stop block 120 will provide a reverse resistance, effectively limiting the sliding block 110 from falling out. At the same time, the design of the stop block 120 also ensures that the sliding block 110 can smoothly slide along the long groove 102 when needed, without being subjected to excessive resistance.

[0070] The existence of the stop block 120 effectively limits the falling out of the sliding block 110, improving the stability of the entire structure. Even in the case of external force or vibration, the sliding block 110 can be firmly maintained in the long groove 102. This design prevents potential safety risks caused by accidental falling out of the sliding block 110. In application scenarios requiring high precision and stability, this design is particularly important. Compared with traditional structures for preventing the sliding block 110 from falling out, the design of the present embodiment is more concise and clear, without the need for additional locking pieces 116 or fixing devices. This reduces manufacturing costs and simplifies the installation and maintenance process. Since the stop block 120 and the opening groove 118 are designed reasonably and are durable, this structure can withstand long-term use and wear and tear, prolonging the service life of the entire device.

[0071] According to one embodiment of the present application, a scale is provided at the opening groove 118 along the length direction of the long groove 102.

[0072] In one embodiment of the present application, the long groove 102 is further optimized. Specifically, along the length direction of the long groove 102, a scale is arranged at the position of the open groove 118. The scale has clear and accurate graduation lines, and is consistent with the length direction of the long groove 102. The material of the scale can be selected from wear-resistant and corrosion-resistant materials to ensure its stability and reliability during long-term use.

[0073] The scale not only provides a visual measurement reference for the user, but also greatly simplifies the operation process. The user can quickly and accurately determine the position of the slider 110 in the long groove 102 by observing the graduation lines on the scale, thereby achieving precise adjustment of the position of the wheelset marking device.

[0074] In addition, the design of the scale also considers the convenience of user operation. For example, the scale can be designed to be detachable or adjustable, so that the user can replace or adjust it according to actual needs. At the same time, the scale can also be marked with easily identifiable marks or symbols to help the user more accurately read the scale value.

[0075] The scale provides a visual measurement reference for the user, allowing the user to quickly and accurately determine the position of the slider 110 in the long groove 102. This helps to improve the adjustment accuracy and measurement accuracy of the wheelset marking device. By observing the graduation lines on the scale, the user can easily achieve precise adjustment of the position of the wheelset marking device without the need for complex calculations or measurements. This greatly simplifies the operation process and improves work efficiency. The design of the scale takes into account the convenience of user operation, making it easier and more enjoyable for the user to use the wheelset marking device. At the same time, the clear graduation lines and easily identifiable marks on the scale also allow the user to more accurately read the scale value, further enhancing the user experience. The scale allows the wheelset marking device to be suitable for different sizes and types of wheelsets. The user can adjust the position of the slider 110 in the long groove 102 according to actual needs and accurately measure it through the scale, thereby ensuring that the wheelset is properly supported and marked.

[0076] According to one embodiment of the present application, the movable support seat 106 further comprises a movable support wheel, and a transmission shaft 122 is arranged on the movable support wheel. One end of the transmission shaft 122 extending out of the open groove 118 is provided with a second handle 124.

[0077] In one embodiment of the present application, the design of the movable support seat 106 is further optimized and enhanced. In addition to the previously mentioned design elements such as the long groove 102, the open groove 118, and the scale, this embodiment further increases a movable support wheel on the movable support seat 106, and is equipped with a transmission shaft 122 and a second handle 124.

[0078] Specifically, the movable support wheel is mounted on the movable support seat 106 so as to be able to flexibly roll or rotate when needed, thereby achieving effective support for wheel pairs of different sizes and types. The surface of the movable support wheel can be made of wear-resistant and anti-skid material to ensure its stability and reliability during long-term use.

[0079] The transmission shaft 122, as a key component of the movable support wheel, is firmly fixed at the center of the movable support wheel and extends out of one end of the open slot 118. The design of the transmission shaft 122 allows the user to adjust the position or angle of the movable support wheel by rotating it, thereby achieving precise control over the wheel pair support point.

[0080] In order to facilitate the user to operate the transmission shaft 122, the second handle 124 is further provided at the end of the transmission shaft 122 extending out of the open slot 118. The shape and size of the second handle 124 are carefully designed and optimized to ensure that the user can comfortably hold and easily rotate the transmission shaft 122. At the same time, the surface of the second handle 124 can be made of anti-skid material to improve the stability and safety of the user during operation.

[0081] The design of the movable support wheel enables the movable support seat 106 to flexibly adapt to wheel pairs of different sizes and types, thereby providing more stable and reliable support for the user. This helps to improve the applicability and flexibility of the wheel pair marking device. By rotating the transmission shaft 122, the user can accurately adjust the position or angle of the movable support wheel, thereby achieving precise control over the wheel pair support point. This helps to improve the adjustment accuracy and measurement accuracy of the wheel pair marking device. The design of the second handle 124 enables the user to comfortably hold and easily rotate the transmission shaft 122, thereby simplifying the operation process and improving work efficiency. At the same time, the application of anti-skid material also improves the stability and safety of the user during operation, further enhancing the user experience. The movable support wheel, transmission shaft 122 and second handle 124 are made of wear-resistant and corrosion-resistant materials to ensure their stability and reliability during long-term use. This helps to prolong the service life of the entire wheel pair marking device and reduce maintenance costs.

[0082] According to an embodiment of the present application, a mounting hole is formed in the sliding block 110, and the movable support wheel is rotatably mounted in the mounting hole through a bearing.

[0083] In an embodiment of the present application, a mounting hole is formed in the sliding block 110 for mounting the movable support wheel. The movable support wheel is rotatably connected with the mounting hole through a bearing, achieving flexible rotation and stable support of the movable support wheel.

[0084] The installation hole is carefully calculated and planned in terms of its position, size, and shape to perfectly match the active support wheel. This way, when the active support wheel is installed into the installation hole, it can rotate smoothly while providing sufficient support force.

[0085] The bearing, as a key component connecting the active support wheel and the installation hole, has the characteristics of low friction, high wear resistance, and high precision. It allows the active support wheel to rotate freely within the installation hole while maintaining a small rotational resistance and high rotational accuracy. This helps to ensure the stability and reliability of the active support wheel during long-term use.

[0086] In addition, appropriate sealing structures are also provided around the installation hole to prevent impurities such as dust and moisture from entering the inside of the bearing, thereby prolonging the service life of the bearing and maintaining its good operating state.

[0087] The active support wheel is rotationally connected to the installation hole through the bearing, achieving flexible rotation and stable support. This allows the active support seat 106 to adapt to different sizes and types of wheelsets, providing more stable and reliable support. The bearing has the characteristics of low friction and high precision, which can ensure the smooth rotation of the active support wheel within the installation hole. This helps to reduce vibration and noise during rotation, improving the smooth operation of the entire wheelset marking device. The high wear resistance of the bearing and the sealing structure around the installation hole prolong the service life of the active support wheel and the bearing. This helps to reduce maintenance costs and improve the durability of the entire device. By opening the installation hole on the sliding block 110 and using standardized bearings and sealing structures, the installation process of the active support wheel is simplified. This allows users to more conveniently install and maintain the device, improving work efficiency.

[0088] According to an embodiment of the present application, the fixed support seat 104 comprises:

[0089] The pin shaft 126 penetrates the long groove 102 along the width direction of the long groove 102.

[0090] The fixed support wheel 128 is rotatably installed on the pin shaft 126.

[0091] In an embodiment of the present application, the design of the fixed support seat 104 is further optimized and innovated. The fixed support seat 104 mainly comprises two key components, the pin shaft 126 and the fixed support wheel 128, which cooperate to achieve stable and flexible support function.

[0092] The pin shaft 126, as the core component of the fixed support seat 104, is designed to pass through the long groove 102 along the width direction of the long groove 102. The length and diameter of the pin shaft 126 are carefully calculated to ensure that it can be firmly fixed in the long groove 102 while providing sufficient support force. The surface of the pin shaft 126 can be specially treated to improve its wear resistance and corrosion resistance, thereby prolonging its service life.

[0093] The fixed support wheel 128 is rotatably mounted on the pin shaft 126. The design of the fixed support wheel 128 takes into account the friction and support force when contacting the wheel pair to ensure that excessive wear or deformation does not occur during support. The surface of the fixed support wheel 128 can be made of wear-resistant and slip-resistant materials to improve its service life and support stability.

[0094] In addition, the connection between the fixed support wheel 128 and the pin shaft 126 is also carefully designed. They can be connected by bearings, bushings, and other components to achieve smooth and low-friction rotation. This helps to reduce vibration and noise during rotation and improves the smooth operation of the entire wheel pair marking device.

[0095] The pin shaft 126 passes through the long groove 102 along the width direction of the long groove 102, providing a firm support point for the fixed support wheel 128. This helps to ensure that excessive shaking or deformation does not occur during support, thereby improving support stability. The fixed support wheel 128 is rotatably mounted on the pin shaft 126, allowing flexible rotation and the ability to adapt to different wheel pair sizes. This helps to ensure that the wheel pair can move smoothly during marking while reducing friction and wear between the fixed support seat 104. The pin shaft 126 and the fixed support wheel 128 are made of wear-resistant and corrosion-resistant materials and are specially treated to improve their service life. This helps to reduce maintenance costs and improve the durability of the entire device.

[0096] According to an embodiment of the present application, the rim shape of the movable support wheel and the rim shape of the fixed support wheel 128 are adapted to the shape of the tread of the wheel pair.

[0097] In an embodiment of the present application, the rim shape of the movable support wheel and the rim shape of the fixed support wheel 128 are specially designed to adapt to the shape of the tread of the wheel pair. The main purpose of this design is to ensure that the support wheel and the wheel pair can form a good contact and support relationship, thereby improving the stability and precision of the entire wheel pair marking device.

[0098] To achieve this goal, the rim shape of the active support wheel and the fixed support wheel 128 can adopt various shapes such as cylindrical, conical or conical drum shape. The choice of these shapes depends on the specific shape of the wheel tread and the working requirements of the scribing device. For example, if the tread of the wheel set is conical, the rims of the support wheels can also be designed to be conical to ensure that they can closely fit and provide stable support between them.

[0099] In addition, the width, height and material of the rim can also be adjusted according to actual needs. For example, the width of the rim can be selected according to the size and weight of the wheel set to ensure sufficient support area and strength. The height of the rim can be designed according to the working height and accuracy requirements of the scribing device to ensure that the support wheels can accurately contact the wheel set and provide stable support.

[0100] Since the rim shape of the support wheel matches the shape of the wheel tread, they can form a good contact relationship. This helps to reduce the shaking and deformation during the support process, thereby improving the stability of the entire wheel set scribing device. The close fit between the support wheel and the wheel set helps to reduce errors and deviations during scribing. This helps to improve scribing accuracy and meet higher working requirements. Since the contact area between the support wheel and the wheel set is larger and more uniform, the pressure and wear per unit area can be reduced. This helps to prolong the service life of the support wheel and the entire scribing device. This design makes the scribing device suitable for wheel sets of different shapes and sizes. This helps to improve the versatility and adaptability of the scribing device, making it able to meet a wider range of working requirements.
