Description

Technical Field

[0001] This application relates to the field of railway data acquisition equipment technology, and in particular to a mounting device for portable data acquisition equipment. Background Technology

[0002] Heavy-haul railways play a crucial role in mountainous transportation systems. These railways are characterized by high transport loads, steep gradients, and complex operating environments. Due to the enormous transport loads, the pressure exerted by trains on the tracks far exceeds that of ordinary railways, meaning that even minor changes in track condition can affect train operation safety. Steep gradients increase the difficulty and risk of train operation, placing higher demands on vehicle dynamics. Furthermore, the complex operating environment, such as the variable climate and geological conditions in mountainous areas, also has numerous adverse effects on railway facilities and train operation.

[0003] Given these characteristics, real-time data collection on track conditions, vehicle dynamics parameters, and environmental data for heavy-haul railways in mountainous areas is particularly urgent. This data plays an irreplaceable role in ensuring safe railway operation, optimizing transportation efficiency, and conducting scientific maintenance management. For example, real-time monitoring of track conditions allows for the timely detection of track wear and deformation, enabling advance maintenance and preventing train accidents caused by track faults. Real-time acquisition of vehicle dynamics parameters helps understand train performance under different operating conditions, providing a basis for optimizing train design and operating strategies. Furthermore, the collection of environmental data provides a reference for coping with complex climate and geological changes in mountainous areas, ensuring stable railway operation under various environments.

[0004] However, in related technologies, the fixing methods for data acquisition equipment on heavy-haul railways in mountainous areas mostly still use traditional methods such as bolted connections or manual hand-held operation. These traditional methods have many technical pain points, which seriously restrict the effective implementation of data acquisition work.

[0005] For example, insufficient vibration resistance. Heavy-haul trains generate high-frequency vibrations and impacts during operation, which can significantly affect data acquisition equipment. Current mounting methods are insufficient to effectively buffer and absorb this vibrational energy, leading to equipment loosening. Once loose, the acquired data will not only be distorted, failing to accurately reflect the actual conditions of the track, vehicle, and environment, but long-term vibration and impact can also damage the equipment, increasing maintenance costs and affecting the continuity of data acquisition.

[0006] For example, it has poor environmental adaptability. The fixtures in related technologies are poorly designed to adapt to the complex and varied terrain conditions in mountainous areas, and cannot achieve multi-angle locking, resulting in unstable equipment installation and further affecting the quality of data acquisition and the reliability of the equipment.

[0007] In summary, the fixed acquisition equipment methods in related technologies can no longer meet the actual data acquisition needs of heavy-haul railways in mountainous areas. Utility Model Content

[0008] Based on this, a mounting device for a portable data acquisition device is provided, which can meet the actual needs of heavy-haul railways in mountainous areas for data acquisition, improve the quality and efficiency of data acquisition, and ensure the safe and stable operation of heavy-haul railways in mountainous areas.

[0019] The third locking element is configured to lock the rotating base and the support base; or, to release the rotating base and the support base.

[0020] In one embodiment, the rotating base includes a connecting base and a transition body, the transition body being fixedly connected to the connecting base, the connecting base being detachably connected to the support base, and the transition body being detachably connected to the first rotating part.

[0021] In one embodiment, the clamping mechanism includes at least one clamping part connected to the second rotating part;

[0022] The clamping part is configured to clamp the object to be clamped.

[0023] In one embodiment, the clamping part includes a first clamping body, a second clamping body, and an adjusting member.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] In some exemplary embodiments, such as Figure 1 , Figure 2 As shown, a fixing device for a portable data acquisition device includes a support base 1, a rotating structure 2, a vibration damping structure 3, and a clamping mechanism 4. The various parts cooperate with each other to achieve stable fixing and flexible adjustment of the data acquisition device.

[0040] The support base 1 serves as the basic support in the entire fixing device, providing a stable installation platform for the rotating structure 2, thereby improving the stability of the entire fixing device.

[0041] In practical applications, the support base 1 can be installed to the preset position in several ways. One installation method is bolt fixing. Specifically, several bolt holes are preset on the support base 1, and corresponding threaded holes are also set at preset positions, such as fixed brackets next to heavy-haul railways in mountainous areas, equipment installation platforms, and inside vehicles. By passing the bolts through the bolt holes of the support base 1 and screwing them into the threaded holes at the preset positions, the support base 1 is reliably fixed. This bolt fixing method has high connection strength and can withstand large external forces, ensuring that the support base 1 remains stable under various working conditions, providing a solid support foundation for subsequent components such as the rotating structure 2.

[0042] Another installation method is to use adhesive or adsorption. For example, an adhesive layer can be provided at the bottom of the support base 1. This adhesive layer is made of high-strength adhesive material, giving it good adhesion and durability, and maintaining a stable adhesion effect under different environmental conditions. For example, in the application scenario of heavy-haul railways in mountainous areas, various harsh conditions such as high temperature, low temperature, humidity, and vibration may be encountered, but this adhesive material can still ensure that the support base 1 is firmly adhered to the preset position. The preset position can be a smooth metal surface, plastic surface, etc. Adhesive installation does not require complicated drilling, tapping, or other operations. The installation process is simple and quick, especially suitable for some temporary installation scenarios. For example, when short-term data collection is required in a specific area, the support base 1 can be quickly installed and easily removed after the data collection task is completed.

[0043] Alternatively, an adsorption device, such as a vacuum suction cup, can be provided at the bottom of the support base 1. By drawing air out of the suction cup to create negative pressure, the support base 1 is adsorbed at a preset position, such as a smooth glass surface or a smooth and flat plane. For example, the support base 1 includes a suction cup 11 and a pressing plate 12, and the pressing plate 12 is connected to the suction cup 11 in a close fit through a third locking member 7.

[0044] The suction cup 11 is made of weather-resistant silicone with a Shore hardness of 60-70, and its diameter is, for example, but not limited to, 60mm. The surface of the suction cup 11 can be provided with anti-slip textures to facilitate stable adhesion to glass or a platform.

[0045] The clamping disc 12 includes, for example, a disc body 121 and a clamping support body 122. The disc body 121 is fitted and connected to the suction cup 11, serving a connection and sealing function. The clamping support body 122 is located on the side of the disc body 121 away from the suction cup 11, providing installation support for the third locking element 7. The third locking element 7 is, for example, a bolt. Both the disc body 121 and the clamping support body 122 are provided with a first screw hole 123 that mates with the third locking element 7, and the suction cup 11 is provided with a corresponding first connecting hole 111. During installation, one end of the third locking element 7 is screwed through the first screw hole 123 and rotatably connected to the suction cup 11. At the same time, a reinforcing ring 112 can be provided around the first connecting hole 111. The reinforcing ring 112 can effectively improve the local strength of the suction cup 11 and prevent the service life and adsorption performance of the suction cup 11 from being affected by the opening.

[0046] It should be noted that the number of suction cups 11, clamping plates 12, and third locking components 7 in the aforementioned support base 1 can be set according to actual installation needs; one, two, or more can be used. Using two components allows for better balance of force on the support base 1 during installation, improving installation stability. This adhesive or magnetic installation method provides more options for the installation of the support base 1, especially suitable for scenarios with special requirements for the installation location, such as confined spaces or areas where drilling is not possible, enabling quick and convenient installation of the support base 1 in a suitable position.

[0047] In this embodiment, as Figure 1 , Figure 2 As shown, the rotating structure 2 is used to achieve multi-angle adjustment. The rotating structure 2 includes a rotating base 21, a first rotating part 22, and a second rotating part 23. The rotating base 21 is connected to the support base 1, providing a stable support platform for the entire rotating structure 2. In actual assembly, the rotating base 21 can be fixed to the support base 1 by bolts, welding, or other methods to ensure a firm and reliable connection between the two. For example, the third locking member 7 can accommodate the connection between the rotating base 21 and the support base 1, simplifying the overall structure and improving installation efficiency.

[0048] The first rotating part 22 is rotatably connected to the rotating base 21. The first rotating part 22 can rotate relative to the rotating base 21 along a first plane direction, for example, the horizontal section shown in the figure. This rotation method allows the fixing device to be angled in the horizontal direction to meet the clamping requirements of different horizontal angles. Exemplarily, the fixing device also includes a first locking member 5, such as a bolt. The first rotating part 22 is adjustablely connected to the rotating base 21 through the first locking member 5. The first rotating part 22 is provided with a second screw hole 221, and the rotating base 21 is provided with a third screw hole 211. One end of the first locking member 5 can pass through the second screw hole 221 and be screwed into the third screw hole 211. For example, when the first locking member 5 is driven to rotate clockwise or counterclockwise, the first rotating part 22 and the rotating base 21 can be locked together, making the first rotating part 22 and the rotating base 21 tightly connected, fixing the first rotating part 22 at the target angle. When the first locking member 5 is driven to rotate in a counterclockwise or clockwise direction, the first rotating part 22 and the rotating base 21 can be released, so that a gap appears between the first rotating part 22 and the rotating base 21. At this time, the first rotating part 22 can be driven to rotate, thereby adjusting the rotation angle of the first rotating part 22.

[0049] The second rotating part 23 is rotatably connected to the first rotating part 22. The second rotating part 23 can rotate relative to the first rotating part 22 along a second plane direction. The first and second plane directions are perpendicular to each other. The second plane direction is the vertical section shown in the figure, enabling pitch adjustment, i.e., adjusting the angle of the clamping mechanism 4 in the vertical direction. Exemplarily, the fixing device also includes a second locking member 6, such as a bolt. The second rotating part 23 is adjustablely connected to the first rotating part 22 via the second locking member 6. The second rotating part 23 is provided with a fourth screw hole 231, and the first rotating part 22 is provided with a fifth screw hole 222. The second locking member 6 is screwed into the fourth screw hole 231 and the fifth screw hole 222 respectively. For example, when the second locking member 6 is driven to rotate clockwise or counterclockwise, it can lock the second rotating part 23 and the first rotating part 22, making the first rotating part 22 and the second rotating part 23 tightly connected together, fixing the second rotating part 23 at the target angle. When the second locking member 6 is driven to rotate in a counterclockwise or clockwise direction, the second rotating part 23 and the first rotating part 22 can be released, so that there is a gap between the first rotating part 22 and the second rotating part 23. At this time, the second rotating part 23 can be driven to rotate, thereby adjusting the rotation angle of the second rotating part 23.

[0050] The first rotating part 22 and the second rotating part 23 cooperate to achieve rotation in different directions, greatly satisfying the need for clamping at multiple angles and improving the flexibility of the rotating structure 2. In actual use, the operator can flexibly adjust the rotation angle of the first rotating part 22 and the second rotating part 23 according to the installation position and acquisition angle of the acquisition device, so that the clamping mechanism 4 can accurately align with the object to be clamped, thereby achieving precise fixation of the acquisition device.

[0051] It should be noted that the aforementioned rotating base 21 and the first rotating part 22, as well as the first rotating part 22 and the second rotating part 23, can be embedded or plugged in by multiple connecting lugs, which can achieve alignment installation and optimize the overall space occupied.

[0052] To improve the reliability of the rotating base 21 during connection, the rotating base 21 may include a connecting base 212 and a transition body 213. The transition body 213 is fixedly connected to the connecting base 212. The connecting base 212 may be flat, increasing the base area of ​​the rotating base 21 and thus improving its stability. The transition body 213 may be trapezoidal, increasing the local height of the rotating base 21 and thereby raising the height of the first rotating part 22 to ensure that the first rotating part 22 does not interfere with other components when rotating.

[0053] The connecting base 212 and the support base 1 are detachably connected. The third locking member 7 can be used to achieve a tight connection between the connecting base 212 and the support base 1, and the first locking member 5 can be used to achieve a tight connection between the adapter 213 and the first rotating part 22.

[0054] In this embodiment, as Figure 1 , Figure 2 As shown, the vibration damping structure 3 is sandwiched between the rotating base 21 and the support base 1 to enhance the vibration resistance of the fixing device. The vibration damping structure 3 can be made of materials or structures with vibration damping properties, such as rubber vibration damping pads. This gives the vibration damping structure 3 good elasticity and damping characteristics, effectively buffering and absorbing high-frequency vibrations and impacts generated during train operation. In actual installation, the rubber vibration damping pad is placed between the rotating base 21 and the support base 1, and the rotating base 21, rubber vibration damping pad, and support base 1 are fixed together using bolts or other fasteners. When the train is in motion, the generated vibration energy is first transmitted to the vibration damping structure 3. The rubber vibration damping pad, through its elastic deformation and damping effect, converts the vibration energy into heat energy and dissipates it, thereby preventing the vibration energy from being directly transmitted to the data acquisition equipment or other components of the fixing device, preventing equipment loosening, improving overall stability, and ensuring the accuracy of the data collected by the data acquisition equipment.

[0055] Alternatively, the vibration damping structure 3 may include an elastic element 31, located between the support base 1 and the rotating base 21. The elastic element 31, such as a spring, buffers vibration through its elastic deformation, offering advantages such as simple structure and low cost. There may be one or multiple elastic elements 31, which can be separately installed and fixedly connected to the support base 1 and the rotating base 21 to improve vibration resistance; or they can be correspondingly fitted onto the third locking element 7 to position and limit the elastic element 31, preventing it from shifting under pressure.

[0056] When the train is in motion, it generates high-frequency vibrations and impacts. The vibration damping structure 3 can buffer and absorb these vibration energies, prevent the acquisition equipment or fixing devices from becoming loose, improve overall stability, and ensure the accuracy of the data collected by the acquisition equipment.

[0057] In this embodiment, as Figure 1 , Figure 2 As shown, the clamping mechanism 4 is connected to the second rotating part 23. The clamping mechanism 4 is configured to clamp an object to be clamped, such as a data acquisition device. The angle of the clamping mechanism 4 can be changed by rotating the structure 2 to meet different clamping requirements or clamping positions. The clamping mechanism 4 can take various forms, such as mechanical grippers or elastic clamps, to achieve the clamping of the data acquisition device.

[0058] In one example, the clamping mechanism 4 includes a clamping part 41 connected to the second rotating part 23. The clamping part 41 is configured to clamp the object to be clamped, i.e., the acquisition device.

[0059] The clamping part 41 includes a first clamping body 411, a second clamping body 412, and an adjusting member 413. The first clamping body 411 and the second clamping body 412 are arranged opposite to each other, so that a clamping space 414 is formed between the first clamping body 411 and the second clamping body 412. The clamping space 414 is configured to place the object to be clamped. In this embodiment, the clamping space is adapted to a data acquisition device with a width of 45mm to 85mm. Specifically, the first clamping body 411 and the second clamping body 412 are both, for example, L-shaped. The first clamping body 411 has a sliding groove 4111, and part of the structure of the second clamping body 412 can be slidably disposed in the sliding groove 4111, realizing a limiting sliding function and ensuring the stability of the clamping process.

[0060] Adjusting element 413 is connected to the first clamping body 411 and the second clamping body 412 respectively. Adjusting element 413 is used to adjust the distance between the first clamping body 411 and the second clamping body 412. The adjusting element 413 can be, for example, a spring (not shown in the figure). When an external force pulls the first clamping body 411 or the second clamping body 412, the distance between them increases, providing installation space for the object to be clamped. At this time, the adjusting element 413 accumulates elastic potential energy. When the first clamping body 411 or the second clamping body 412 is released, the adjusting element 413 releases the elastic potential energy, causing the first clamping body 411 or the second clamping body 412 to reset, thereby achieving clamping of the data acquisition device.

[0061] Alternatively, the adjusting member 413 may be an adjusting screw, one end of which rotatably passes through the first clamping body 411 and is threadedly connected to the second clamping body 412. When the adjusting member 413 is rotated, the distance between the first clamping body 411 and the second clamping body 412 can be adjusted to clamp or release the object to be clamped.

[0062] It should be noted that the number of clamping parts 41 is not limited to one; it can be set to two, three, or other configurations depending on actual needs. Multiple clamping parts 41 are connected to the second rotating part 23 and located at different positions on the second rotating part 23. This design can meet diverse clamping requirements and is suitable for different clamping scenarios.

[0063] The clamping mechanism 4 also includes an anti-slip layer 42, which is disposed on the inner side of the clamping part 41. An anti-slip layer 42 can be disposed inside both the first clamping body 411 and the second clamping body 412. The anti-slip layer 42 is, for example, an anti-slip rubber pad, and is fixed to the first clamping body 411 and the second clamping body 412 by means of adhesion or other methods. This design can increase the friction between the clamping mechanism 4 and the object to be clamped, effectively preventing the object from falling off and improving the reliability of clamping.

[0064] The installation of fixed data acquisition devices in related technologies typically requires multiple people working together, which not only increases labor costs but also severely limits collaborative work in the confined spaces of mountainous areas, making it difficult to carry out smoothly. Furthermore, in emergency monitoring scenarios, such as sudden natural disasters or equipment malfunctions requiring rapid deployment of data acquisition equipment, the installation methods of fixed devices in related technologies cannot meet the demands of rapid deployment, potentially leading to the inability to obtain critical data in a timely manner and affecting timely handling and decision-making in emergency situations.

[0065] In practical use, this application uses the rotating structure 2 to change the angle of the clamping mechanism 4. For example, when it is necessary to adjust the acquisition angle of the acquisition device, the operator can rotate the first rotating part 22 and the second rotating part 23 to make the clamping mechanism 4 drive the acquisition device to rotate to a suitable angle. At the same time, the clamping mechanism 4 can be flexibly adjusted according to the shape, size and other characteristics of the acquisition device to meet different clamping requirements or clamping positions. For example, for acquisition devices of different specifications, the clamping mechanism 4 can achieve stable clamping of the acquisition device by adjusting parameters such as the opening degree of the clamping part 41 and the clamping force.

[0066] The mounting device for the portable data acquisition equipment disclosed in this application achieves stable fixation, multi-angle adjustment, and effective vibration reduction of the equipment through the coordinated operation of the support base 1, rotating structure 2, vibration damping structure 3, and clamping mechanism 4. This meets the installation requirements of data acquisition equipment in complex environments such as mountainous areas and heavy-haul railways. Furthermore, it eliminates the need for multiple personnel; installation can be performed by a single person, effectively reducing labor costs. The mounting device as a whole meets general waterproof, dustproof, and rustproof requirements, and has an operating temperature range of -30℃ to 70℃ to adapt to various environmental conditions.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
