[0002] Mobile platforms are widely used in container terminal crane equipment and logistics warehousing, such as container terminal crane trolley mechanisms and logistics warehousing mobile platforms. Their precise and efficient operation relies on accurate positioning. Currently, using magnetic nails for positioning mobile platforms is a common method. Specifically, a detector carried by the mobile platform detects magnetic nails pre-laid on the ground or at specific locations to determine the platform's location. However, in existing technologies, magnetic nails are susceptible to electromagnetic interference from surrounding metal objects, which reduces the stability of the positioning signal emitted by the magnetic nails, thus affecting the positioning accuracy of the mobile platform. Utility Model Content

[0003] To address at least one of the problems mentioned in the background art, this utility model provides a mobile platform positioning magnetic nail mounting component and a mobile platform positioning system, which can improve the positioning accuracy of the mobile platform.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] In a first aspect, this utility model provides a positioning magnetic nail mounting component for a mobile platform. The mounting component is spaced along the moving path of the mobile platform, and the magnetic nail is used to position the mobile platform. The mounting component includes a main body made of nylon.

[0006] The first end of the main body along the axial direction has a receiving cavity for installing magnetic nails. The inner wall of the receiving cavity is provided with an elastic locking structure to prevent the magnetic nails from falling off along the axial direction.

[0007] The second end of the main body along the axial direction has a threaded hole, and the mounting part is configured to be screwed onto the corresponding threaded connector through the threaded hole. The receiving cavity and the threaded hole are spaced apart along the axial direction of the main body.

[0008] As an optional implementation, the distance between the receiving cavity and the threaded hole along the body axis is greater than 30 mm.

[0009] As an optional implementation, the outer peripheral surface of the main body has reinforcing ribs extending along the axial direction.

[0010] As an optional implementation, the main body includes a first telescopic section and a second telescopic section, which are sleeved together along the axial direction.

[0011] As an optional implementation, it also includes a positioning screw. The first telescopic segment has a plurality of first positioning holes spaced apart along the axial direction, and the second telescopic segment has a plurality of second positioning holes spaced apart along the axial direction. The first positioning holes and the second positioning holes are arranged radially opposite to each other. The positioning screw is configured to pass through the first positioning holes and the second positioning holes radially to lock the relative position of the first telescopic segment and the second telescopic segment.

[0012] As an optional implementation, the elastic locking structure includes multiple spring pieces distributed circumferentially along the inner wall of the receiving cavity, with the first end of the spring piece connected to the inner wall of the receiving cavity and the second end of the spring piece extending obliquely toward the bottom of the receiving cavity.

[0013] As an alternative implementation, the second end of the spring is arc-shaped and bent toward the inner wall of the adjacent receiving cavity.

[0014] As an optional implementation, a dust cover is also included, which is detachably mounted over the opening of the receiving cavity.

[0015] Secondly, this utility model also provides a mobile platform positioning system, including a track, a mobile platform, a detector, a mounting frame, and mounting components. The mobile platform is movably mounted on the track, and the detector is mounted on the mobile platform.

[0016] Multiple mounting brackets are spaced apart along the side of the track. Mounting components are screwed onto threaded connectors on the mounting brackets via threaded holes. Magnetic nails are installed in the receiving cavities of the mounting components. Detectors are configured to determine the position of the moving platform by sensing the magnetic field signal of the magnetic nails.

[0017] As an optional implementation, the distance between the magnetic nail and the detector is 60mm-120mm.

[0018] The positioning magnetic nail mounting component for the mobile platform provided by this utility model is spaced along the moving path of the mobile platform. The magnetic nails are used to position the mobile platform. The mounting component includes a main body made of nylon. The first end of the main body along the axial direction has a receiving cavity for mounting the magnetic nails. The inner wall of the receiving cavity is provided with an elastic locking structure to prevent the magnetic nails from falling off along the axial direction. The second end of the main body along the axial direction has a threaded hole. The mounting component is configured to be screwed onto a corresponding threaded connector through the threaded hole. The receiving cavity and the threaded hole are spaced apart along the axial direction of the main body.

[0019] The mobile platform positioning magnetic nail mounting component provided by this utility model uses a nylon body, which combines insulation and non-magnetic properties. A certain distance is maintained between its internal cavity and the threaded hole at the rear end, physically isolating the magnetic nail installed in the cavity from the metal connector at the threaded hole. This effectively blocks interference from metal components to the magnetic field signal of the magnetic nail, ensuring that the detector carried by the mobile platform can accurately receive a pure magnetic field positioning signal, thus improving the positioning accuracy of the mobile platform. Secondly, the elastic locking structure on the inner wall of the cavity generates a clamping force through elastic deformation. Under complex operating conditions such as vibration and impact during the operation of the mobile platform, it can stably constrain the axial displacement of the magnetic nail, avoiding the loosening and detachment problems that are prone to occur in traditional rigid connections, and ensuring the long-term reliability of the magnetic nail positioning reference. Furthermore, the threaded hole design at the rear end of the main body not only enables quick screw-on fixing to the mounting surface, but its self-locking characteristic also enhances the overall structure's vibration resistance. Combined with the shock-absorbing and buffering properties of the nylon material, this further improves installation stability, making the detector's magnetic field sensing more sensitive and accurate.

[0050] Mobile platforms are widely used in container terminal crane equipment and logistics warehousing, such as container terminal crane trolley mechanisms and logistics warehousing mobile platforms. Their precise and efficient operation relies on accurate positioning. Currently, using magnetic nails for positioning mobile platforms is a common method. Specifically, a detector carried by the mobile platform detects magnetic nails pre-laid on the ground or at specific locations to determine the platform's location. However, in existing technologies, magnetic nails are susceptible to electromagnetic interference from surrounding metal objects, which reduces the stability of the positioning signal emitted by the magnetic nails, thus affecting the positioning accuracy of the mobile platform.

[0051] In view of this, the present invention provides a positioning magnetic nail mounting component for a mobile platform, comprising a nylon body; a first axial end of the body having a receiving cavity for mounting a magnetic nail, the inner wall of which is provided with an elastic locking structure to prevent the magnetic nail from falling off axially; a second axial end of the body having a threaded hole, the mounting component being configured to be screwed onto a corresponding threaded connector through the threaded hole, the receiving cavity and the threaded hole being spaced apart axially along the body.

The internal receiving cavity and the rear threaded hole maintain a certain distance, physically isolating the magnetic nail installed in the receiving cavity from the metal connector at the threaded hole, effectively blocking interference from metal components to the magnetic field signal of the magnetic nail, ensuring that the detector carried by the mobile platform can accurately receive a pure magnetic field positioning signal, and improving the positioning accuracy of the mobile platform. Furthermore, the elastic locking structure on the inner wall of the receiving cavity generates a clamping force through elastic deformation, which can stably constrain the axial displacement of the magnetic nail under complex operating conditions such as vibration and impact during the operation of the mobile platform, avoiding the loosening and falling-off problems that are prone to occur in traditional rigid connections, and ensuring the long-term reliability of the magnetic nail positioning reference.

[0053] You can refer to this. Figures 1 to 5 This utility model embodiment provides a mobile platform positioning magnetic nail mounting component 100. The mounting component 100 is spaced along the moving path of the mobile platform 220. The magnetic nails 300 are used to position the mobile platform 220. The mounting component 100 includes a nylon body 110. The first end of the body 110 along the axial direction has a receiving cavity 111 for mounting the magnetic nails 300. The inner wall of the receiving cavity 111 is provided with an elastic locking structure to prevent the magnetic nails 300 from falling off along the axial direction. The second end of the body 110 along the axial direction has a threaded hole 112. The mounting component 100 is configured to be screwed onto a corresponding threaded connector through the threaded hole 112. The receiving cavity 111 and the threaded hole 112 are spaced apart along the axial direction of the body 110.

[0054] The mobile platform positioning magnetic nail mounting component 100 provided in this embodiment of the utility model adopts a nylon body 110, which has both insulation and non-magnetic properties. A certain distance is maintained between its internal receiving cavity 111 and the rear threaded hole 112, so that the magnetic nail 300 installed in the receiving cavity 111 and the metal connector at the threaded hole 112 form physical isolation, effectively blocking the interference of metal components on the magnetic field signal of the magnetic nail 300. This ensures that the detector 230 carried by the mobile platform 220 can accurately receive a pure magnetic field positioning signal, improving the positioning accuracy of the mobile platform 220. Secondly, the elastic locking structure on the inner wall of the receiving cavity 111 generates a clamping force through elastic deformation. Under complex working conditions such as vibration and impact during the operation of the mobile platform 220, it can stably constrain the axial displacement of the magnetic nail 300, avoiding the loosening and falling-off problems that are prone to occur in traditional rigid connections, and ensuring the long-term reliability of the magnetic nail 300 positioning reference. In addition, the threaded hole 112 at the rear end of the main body 110 not only enables quick screwing and fixing with the mounting base, but its self-locking characteristic of thread engagement also enhances the vibration resistance of the overall structure. Combined with the shock absorption and buffering characteristics of nylon material, it further improves the installation stability and makes the magnetic field sensing of detector 230 more sensitive and accurate.

[0055] In the above embodiments, the distance between the receiving cavity 111 and the threaded hole 112 along the axial direction of the main body 110 can be greater than 30mm. It is understood that the main body 110, made of nylon, has non-magnetic properties. When the distance between the receiving cavity 111 and the threaded hole 112 is greater than 30mm, a reliable magnetic isolation space can be formed between the magnetic nail 300 and any metal connectors that may exist around the threaded hole 112. This greatly reduces the risk of metal interference with the magnetic field signal of the magnetic nail 300, making the detector 230 carried by the mobile platform 220 receive magnetic signals more stably and accurately, effectively ensuring the accuracy of positioning. At the same time, the elastic locking structure on the inner wall of the receiving cavity 111 further works in concert to firmly lock the magnetic nail 300, ensuring that its displacement amplitude is controlled within a very small range under the complex operating environment of frequent starts and stops and vibrations of the mobile platform 220, thus ensuring the stability of the positioning reference. If the distance between the receiving cavity 111 and the threaded hole 112 is less than 30mm, the magnetic field interference generated by the metal connector (for fixing the mounting part 100) will easily interfere with the magnetic field of the magnetic nail 300, causing the magnetic signal strength received by the detector 230 of the mobile platform 220 to be unstable, and the effective detection distance will also be shortened, affecting the reliability of remote positioning.

[0056] In the above embodiments, the outer peripheral surface of the main body 110 may have axially extending reinforcing ribs 113. When the outer peripheral surface of the main body 110 is provided with axially extending reinforcing ribs 113, during the operation of the mobile platform 220, facing frequent starts, stops, accelerations, decelerations, and possible external impacts, the reinforcing ribs 113 can effectively disperse the force, preventing the main body 110 from deforming or breaking due to excessive pressure or impact, greatly enhancing the durability of the mounting component 100. The presence of reinforcing ribs 113 also helps the mounting component 100 dissipate heat. Due to the long-term operation of the mobile platform 220, heat may accumulate inside the mounting component 100. The axially extending reinforcing ribs 113 increase the contact area with the outside air, which is conducive to heat dissipation, preventing the performance of the nylon material from deteriorating due to overheating, and further extending the service life of the mounting component 100.

[0057] In the above embodiments, the main body 110 includes a first telescopic section 114 and a second telescopic section 115, which are axially sleeved together. It is understood that in practical applications, due to the different structural designs of different mobile platforms 220, the varying heights and positions of the detector 230, and the complex and variable operating environment, factors such as ground flatness and subtle differences in the equipment mounting base can all affect the initial relative distance between the magnetic nail 300 and the detector 230. At this point, by flexibly adjusting the splicing length of the first telescopic section 114 and the second telescopic section 115, it can be ensured that the magnetic nail 300 and the detector 230 always maintain the most suitable distance, which greatly optimizes the sensitivity and accuracy of the detector 230 in receiving the magnetic field signal of the magnetic nail 300, effectively avoiding signal interference or attenuation problems caused by too close or too far distance, enabling the mobile platform 220 to obtain stable and reliable positioning information in real time. Compared with the traditional fixed-length mounting part 100, this telescopic adjustment design greatly improves the convenience and adaptability of installation. Whether it is in the early stage of equipment debugging or in the later stage when the position of the magnetic nail 300 needs to be adjusted due to equipment maintenance or upgrade, the operator can complete the operation quickly and efficiently, significantly reducing the time cost required for installation and maintenance, and providing strong support for the efficient and accurate positioning operation of the mobile platform 220.

[0058] In the above embodiments, a positioning screw 120 may also be included. The first telescopic segment 114 has a plurality of first positioning holes 1141 spaced apart along the axial direction, and the second telescopic segment 115 has a plurality of second positioning holes 1151 spaced apart along the axial direction. The first positioning holes 1141 and the second positioning holes 1151 are arranged radially opposite to each other. The positioning screw 120 is configured to pass radially through the first positioning holes 1141 and the second positioning holes 1151 to lock the relative positions of the first telescopic segment 114 and the second telescopic segment 115. It can be understood that when it is necessary to adjust the relative distance between the magnetic nail 300 and the detector 230 on the moving platform 220, the operator can first use a screwdriver to loosen the positioning screw 120, allowing the first telescopic segment 114 and the second telescopic segment 115 to be unlocked and move relatively freely. Subsequently, based on the actual site conditions and precise measurement requirements, the two telescopic sections were manually and flexibly stretched or compressed axially. During this process, the first positioning hole 1141 on the first telescopic section 114 and the corresponding second positioning hole 1151 on the second telescopic section 115 were carefully observed and compared to accurately find the matching position of the two along the radial direction. Finally, the screwdriver was used again to re-insert the positioning screw 120 radially into the corresponding first positioning hole 1141 and second positioning hole 1151, and tightened securely to successfully lock the adjusted relative position of the first telescopic section 114 and the second telescopic section 115, efficiently completing the adjustment operation.

[0059] The advantages of this adjustment method for the first telescopic section 114 and the second telescopic section 115 are obvious. First, it allows for precise adjustment of the position of the magnetic nail 300. Whether dealing with the complex and varied structures of different mobile platforms 220 or adapting to uneven and changing operating environments, it ensures that the magnetic nail 300 and the detector 230 maintain the perfect distance, ensuring a stable magnetic signal received by the detector 230 and greatly improving positioning accuracy. Second, it is simple and convenient to operate. The entire adjustment process can be completed with just a simple tool like an ordinary screwdriver, without the need for specialized or complex equipment. This greatly reduces the skill requirements for operators, saves time, and improves the efficiency of equipment debugging and maintenance. Furthermore, the reliable connection between the positioning screw 120 and the positioning hole ensures that even when the mobile platform 220 frequently accelerates or decelerates during operation, or is subjected to strong vibrations or impacts, the relative stillness of the two telescopic sections can be maintained, ensuring that the position of the magnetic nail 300 remains unchanged.

[0060] In the above embodiments, the elastic locking structure may include multiple spring pieces 130 spaced circumferentially along the inner wall of the receiving cavity 111. The first end of each spring piece 130 is connected to the inner wall of the receiving cavity 111, and the second end of each spring piece 130 extends obliquely towards the bottom of the receiving cavity 111. When installing the magnetic nail 300, it can be axially inserted into the receiving cavity 111. The magnetic nail 300 will contact the second end of the oblique spring piece 130. Due to the elasticity of the spring piece 130, it will undergo elastic deformation under the pressure of the magnetic nail 300, bending towards the inner wall of the receiving cavity 111. After the magnetic nail 300 is fully installed, the restoring force generated by the elastic deformation of the spring piece 130 will act on the surface of the magnetic nail 300. Multiple spring pieces 130 apply pressure evenly to the magnetic nail 300 circumferentially, forming a stable constraint environment that firmly fixes the magnetic nail 300 within the receiving cavity 111, preventing the magnetic nail 300 from falling off axially. During operation, the mobile platform 220 is subjected to various external forces such as vibration, acceleration, and deceleration. The elastic locking structure effectively counteracts these forces. Firstly, the elastic properties of the spring 130 allow it to absorb and buffer some of the impact force, reducing the direct impact of external forces on the magnetic nail 300 and preventing it from loosening or shifting due to vibration. Secondly, even if the magnetic nail 300 is subjected to a certain axial force, the clamping force generated by the spring 130 effectively resists it, maintaining the stable position of the magnetic nail 300 and ensuring that it continuously and stably emits positioning signals. This guarantees that the detector 230 carried by the mobile platform 220 can accurately receive the signals, thereby achieving precise positioning.

[0061] In the above embodiment, the second end of the spring piece 130 can be arc-shaped and bent towards the inner wall of the adjacent receiving cavity 111. It can be understood that when the magnetic nail 300 is inserted into the receiving cavity 111 axially, the arc-shaped surface of the second end of the spring piece 130 can effectively guide the magnetic nail 300 to slide smoothly in, reducing jamming and allowing the magnetic nail 300 to quickly and smoothly reach the predetermined position. Simultaneously, the spring piece 130 undergoes elastic deformation under the pressure of the magnetic nail 300, generating a clamping force to firmly hold the magnetic nail 300, preventing axial displacement and detachment of the magnetic nail 300 during subsequent operation of the moving platform 220. When it is necessary to remove the magnetic nail 300, because the second end of the spring piece 130 is arc-shaped and bent inwards, the arc-shaped surface can effectively avoid sharp scratches on the surface of the magnetic nail 300 during the removal process, greatly reducing the risk of scratching the magnetic nail 300 and ensuring that the appearance of the magnetic nail 300 remains intact. This not only facilitates the reuse of the magnetic nail 300, maintains the stability of its magnetic field performance, and extends the service life of the magnetic nail 300, but also makes the entire removal operation more convenient and safe, reducing the possibility of damage to equipment components due to improper operation, and providing a reliable guarantee for the entire process of installation and maintenance of the positioning magnetic nail 300 on the mobile platform 220.

[0062] The above embodiments may further include a dust cover 140, which is detachably mounted on the opening of the receiving cavity 111. It is understood that in practical applications, the operating environment of the mobile platform 220 is complex and variable, and impurities such as dust, debris, oil, and moisture may be present. The dust cover 140 can prevent these impurities from entering the receiving cavity 111, avoiding interference with the magnetic field of the magnetic nail 300 after adhering to its surface, thus preventing the detector 230 on the mobile platform 220 from accurately identifying the position of the magnetic nail 300 and ensuring the normal transmission and reception of the magnetic field signal of the magnetic nail 300. By setting the dust cover 140, the receiving cavity 111 can be kept relatively clean, making the maintenance of the magnetic nail 300 simpler and more efficient, reducing the time cost of cleaning and maintenance.

[0063] Furthermore, this utility model embodiment also provides a mobile platform positioning system 200, including a track 210, a mobile platform 220, a detector 230, a mounting bracket 240, and the mounting member 100 in the above embodiment. The mobile platform 220 is movably disposed on the track 210, and the detector 230 is disposed on the mobile platform 220. There are multiple mounting brackets 240, which are spaced apart on the side of the track 210 along the extension direction of the track 210. The mounting member 100 is screwed onto the threaded connector on the mounting bracket 240 through a threaded hole 112. A magnetic nail 300 is installed in the receiving cavity 111 of the mounting member 100. The detector 230 is configured to determine the position of the mobile platform 220 by sensing the magnetic field signal of the magnetic nail 300. Mounting component 100 includes a nylon body 110; the first axial end of the body 110 has a receiving cavity 111 for mounting a magnetic nail 300, and the inner wall of the receiving cavity 111 is provided with an elastic locking structure to prevent the magnetic nail 300 from falling off along the axial direction; the second axial end of the body 110 has a threaded hole 112, and the mounting component 100 is configured to be screwed onto a corresponding threaded connector through the threaded hole 112, with a gap between the receiving cavity 111 and the threaded hole 112 along the axial direction of the body 110. The mounting component 100, with its nylon body 110, combines insulation and non-magnetic properties. A certain gap is maintained between its internal receiving cavity 111 and the rear threaded hole 112, physically isolating the magnetic nail 300 installed in the receiving cavity 111 from the metal connector at the threaded hole 112, effectively blocking interference from metal components to the magnetic field signal of the magnetic nail 300, ensuring that the detector 230 carried by the mobile platform 220 can accurately receive a pure magnetic field positioning signal, and improving the positioning accuracy of the mobile platform positioning system 200.

[0064] In the above embodiments, the distance between the magnetic nail 300 and the detector 230 can be controlled between 60mm and 120mm. It is understood that when the mobile platform 220 moves on the track 210, the detector 230 needs to accurately sense the magnetic field signal emitted by the magnetic nail 300 to determine the position of the mobile platform 220. If the distance between the magnetic nail 300 and the detector 230 is too close, for example, less than 60mm, the magnetic field signal received by the detector 230 may be too strong, exceeding its optimal sensing range, thus causing saturation or distortion in the detection results and affecting the accuracy of positioning. Simultaneously, an excessively close distance may also make the detector 230 more susceptible to interference from the magnetic field of the magnetic nail 300, reducing the stability of the system. If the distance is greater than 120mm, the magnetic field signal will attenuate rapidly during propagation, and the signal strength received by the detector 230 may be too weak, making it difficult to accurately identify and interpret the magnetic field signal, which will also reduce positioning accuracy. By controlling the distance between the magnetic nail 300 and the detector 230 to 60mm-120mm, the detector 230 can receive a magnetic field signal with moderate intensity and good stability, thereby accurately determining the position of the mobile platform 220 and ensuring the high-precision operation of the mobile platform positioning system 200.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
