Description

Technical Field

[0001] This utility model relates to the field of railway locomotive testing technology, specifically a diesel locomotive weight distribution testing platform. Background Technology

[0002] In the railway transportation sector, the axle load distribution of diesel locomotives directly affects operational safety and mechanical lifespan. Significant deviations in axle loads lead to uneven wheel-rail contact stress, exacerbating component wear and potentially causing traction loss or dynamic instability. Currently, the industry commonly uses track weighing systems for axle load detection, typically by placing sensors on top of the rails to measure wheel tread loads. While widely used, this method has fixed detection points, limiting its adaptability to different wheelbase models. Adjusting the detection layout often requires mechanical modifications to the track structure. Furthermore, traditional detection methods struggle to directly obtain stress information at the wheel flange, yet the actual load-bearing state of this area is crucial for analyzing axle load balance. Therefore, current technology lacks a detection scheme that can quickly adapt to various locomotive models and directly measure wheel flange stress, hindering the efficient implementation of locomotive axle load balance analysis. Utility Model Content

[0003] The present invention aims to solve the above problems, thereby providing a testing platform for the weight distribution of internal combustion locomotives that can directly measure the force on the wheel flange.

[0004] The technical solution adopted by this utility model to solve the aforementioned problem is: A weight distribution testing platform for diesel locomotives includes two parallel steel rails. Bases are respectively provided on the inner side of the rails along the length direction. Multiple sets of detachable support seats are correspondingly provided on the two bases along the length direction. The spacing between adjacent support seats is adapted to the wheelbase of the locomotive under test. A weighing sensor is installed in the support seat to support and measure the vertical load transmitted by the bottom surface of the locomotive wheel flange. The bearing surface of the weighing sensor is located at the top. The weighing sensor integrates a wireless signal transmitter that transmits the detected weight signal outward.

[0005] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are: By placing the load cell inside the rail and having its bearing surface facing upward to support the bottom surface of the wheel flange, the vertical load information of the wheel flange can be directly obtained, providing more direct force data for analyzing axle load balance. At the same time, the support base is arranged in a detachable and adjustable manner, which allows the testing platform to flexibly adapt to locomotive models with different wheelbases for measurement, improving the convenience of testing operations and the applicability of the platform.

[0006] As a preferred embodiment, a further technical solution of this utility model is: Furthermore, the base is fixed to the inside of the rail by welding. This fixing method ensures a firm connection and guarantees the stability of the base position during long-term use, providing a reliable foundation for the precise installation of the subsequent support and sensor.

[0007] Furthermore, bolt holes are spaced along the length of the base, and connecting holes are provided on the support base. Bolts that mate with the bolt holes pass through the connecting holes, and the support base and the base are reliably fixed by bolt connection. At the same time, this connection method is easy to disassemble and adjust, which helps to flexibly configure the test points according to the wheelbase of the specific vehicle model.

[0008] Furthermore, a placement slot is provided inside the support base, and the load cell is positioned in the placement slot by plugging or clamping. This structure provides a stable installation position for the sensor, enabling it to maintain a stable posture when subjected to vertical loads, while also facilitating the quick installation and routine maintenance and replacement of the sensor.

[0009] Furthermore, the placement slot is provided with an upwardly protruding positioning rod, and the bottom of the load cell is provided with a positioning hole that cooperates with the positioning rod. The cooperation between the positioning rod and the positioning hole enables quick and accurate positioning when installing the sensor, preventing the sensor from moving horizontally in the placement slot and ensuring that its bearing surface can be accurately aligned with the bottom surface of the wheel flange.

[0010] Furthermore, the weighing sensor is rechargeable, eliminating the hassle of laying power supply lines, reducing installation complexity, and making the deployment of the testing platform more flexible and convenient, especially suitable for temporary or mobile testing tasks in different locations.

[0011] Furthermore, it also includes a main unit, which has a wireless receiver that communicates with the wireless signal transmitter. The main unit also includes a display screen for displaying the weight of each axis and the total weight. The wireless transmission method avoids the need for long-distance cable laying, and the display screen can intuitively and centrally display the weight of each axis and the total weight data, making it convenient for operators to quickly read and record the test results on site.

[0014] A weight distribution testing platform for diesel locomotives includes two parallel steel rails 1. Bases 2 are respectively installed on the inner side of each rail 1 along its length. Each base 2 can be a single unit or composed of several spaced segments. Multiple sets of detachable support seats 3 are correspondingly installed on the two bases 2 along their length. The spacing between adjacent support seats 3 is adapted to the wheelbase of the locomotive under test. A load cell 4 is installed within each support seat 3 to support and measure the vertical load transmitted by the bottom surface of the locomotive wheel flanges. The load-bearing surface of the load cell 4 is located at the top. The load cell 4 integrates a wireless signal transmitter that transmits the detected weight signal outwards.

[0015] Furthermore, the base 2 is fixed to the inside of the rail 1 by welding. This fixing method is firm and can ensure the stability of the position of the base 2 under long-term use, providing a reliable foundation for the subsequent precise installation of the support base 3 and the weighing sensor 4.

[0016] Furthermore, bolt holes are spaced along the length of the base 2. The spacing of the bolt holes is predetermined according to the wheelbase parameters of common locomotive models. The support 3 is provided with connecting holes, through which bolts 5 that cooperate with the bolt holes are passed. The support 3 and the base 2 are reliably fixed by connecting with bolts 5. At the same time, this connection method is easy to disassemble and adjust the position, which helps to flexibly configure the detection points according to the wheelbase of the specific vehicle model.

[0017] Furthermore, a placement slot is provided in the support base 3, and the load cell 4 is positioned in the placement slot by plugging or snapping. This structure provides a stable installation position for the load cell 4, so that it can maintain a stable posture when bearing vertical loads, and at the same time facilitates the quick installation and daily maintenance and replacement of the load cell 4.

[0018] Furthermore, a positioning rod 6 protruding upward is provided in the placement groove, and a positioning hole that cooperates with the positioning rod 6 is provided at the bottom of the load cell 4. The cooperation between the positioning rod 6 and the positioning hole can achieve quick and accurate positioning when installing the load cell 4, avoid the load cell 4 from moving horizontally in the placement groove, and ensure that its bearing surface can be accurately aligned with the bottom surface of the wheel flange.

[0019] Furthermore, the weighing sensor 4 is rechargeable, with an integrated rechargeable battery and a charging interface, eliminating the hassle of laying power supply lines, reducing installation complexity, and making the deployment of the testing platform more flexible and convenient, especially suitable for temporary or mobile testing tasks in different locations.

[0020] Furthermore, it also includes a main unit, which has a wireless receiver that communicates with the wireless signal transmitter. The main unit also includes a display screen for displaying the weight of each axis and the total weight. The wireless transmission method avoids the need for long-distance cable laying, and the display screen can intuitively and centrally display the weight of each axis and the total weight data, making it convenient for operators to quickly read and record the test results on site.

[0021] During operation, the corresponding bolt hole positions are first selected according to the specific model and wheelbase parameters of the diesel locomotive under test. The support base 3 is detachably fixed to the base 2 welded to the inner side of the rail 1 by bolts 5. The corresponding number of detection points are configured according to the number of locomotive axles. When the locomotive drives onto the detection platform, the bottom surface of the wheel flange directly contacts the bearing surface of the top of the weighing sensor 4 inside the support base 3. The weighing sensor 4 accurately measures the vertical load transmitted at the wheel flange and transmits the data through the built-in wireless signal transmitter. After the data is received by the wireless receiver in the host, the weight of each axle and the total weight are displayed on the screen in real time. The rechargeable weighing sensor 4 eliminates the need for complex wiring. The entire detection process does not require mechanical modification of the track structure, realizing convenient detection with rapid deployment and flexible adaptation to various locomotive models, effectively improving the efficiency of locomotive axle load balance analysis.
