Description

Technical Field

[0001] This utility model relates to the field of sensor testing device technology, and specifically to a wheel sensor testing device. Background Technology

[0002] In rail transit systems, wheel sensors are one of the key devices for ensuring train operation safety and achieving automatic control. Their stability and accuracy directly affect train monitoring and dispatching. To ensure reliable operation of wheel sensors, testing and calibration are necessary during manufacturing. However, existing testing methods are insufficient; there is a lack of dedicated equipment that can conveniently and efficiently simulate the passage of train wheelsets to accurately test wheel sensors. Therefore, it is necessary to design a simulation device to meet testing requirements. Utility Model Content

[0003] To address the lack of existing wheel sensor testing equipment on rails, the purpose of this invention is to provide a wheel sensor testing device that simulates the scenario of a train wheelset passing over a wheel sensor, thereby enabling the testing of the wheel sensor.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A wheel sensor testing device includes a movable body with omnidirectional rollers on the inner side of the movable body facing the rail. The movable body is connected to a push rod, and a simulated wheelset is provided on one side of the movable body. When the movable body is pushed along the rail by the push rod, the simulated wheelset triggers a wheel sensor located on the same side of the rail.

[0005] This technical solution features omnidirectional rollers on the inner side of the moving body facing the rail, ensuring stable and smooth movement. A hand-operated lever connects to the moving body, allowing operators to easily push it along the rail to simulate the movement of train wheelsets passing over wheel sensors. The lever also facilitates operator control of the simulation. Simulated wheelsets are located on one side of the moving body; as the body moves along the rail using the hand-operated lever, these simulated wheelsets trigger the wheel sensors located on the same side of the rail. The overall structure is simple, practical, and easy to operate, efficiently completing wheel sensor testing, improving testing efficiency and accuracy, and ensuring the reliable operation of rail transit equipment. In summary, this technical solution effectively triggers wheel sensors by simulating train wheels sliding over them, providing a realistic testing scenario. This allows for convenient and stable simulation of train wheelsets passing over wheel sensors, providing reliable conditions for sensor testing and improving testing efficiency and accuracy.

[0006] Preferably, the simulated wheelset has the same size and shape as the actual train wheelset, and the curvature of the simulated wheelset is adapted to the actual train wheelset, ensuring the consistency and accuracy of the triggering of the wheel sensor.

[0007] Preferably, the moving body includes a top plate, with multiple support plates extending downwards from both sides of the top plate. Universal rollers are provided on the inner sides of both the top plate and the support plates. The universal rollers on the top plate travel along the top of the rail, while the universal rollers on the support plates travel along the side walls of the rail. The top plate has a horizontal extension located outside the support plates on the same side, and the simulated wheelset is installed at the lower end of the horizontal extension. The universal rollers are evenly distributed on the inner sides of the top plate and the support plates, improving the stability of the lifting mechanism's movement on the rail and preventing tilting or jamming.

[0008] Preferably, the push rod is detachably fixed to the top plate. This facilitates the overall storage, transportation, and replacement and maintenance of components, for example, by using threaded connections, snap-fit ​​connections, or other similar methods.

[0009] Preferably, the push rod is a telescopic push rod. The length of the push rod can be adjusted according to the operator's height, operating habits, and testing scenario requirements, optimizing operational convenience. The telescopic push rod and the moving main body are detachable, increasing the applicability and maintenance convenience of the mechanism, meeting different usage scenarios and long-term use needs, and possessing good potential for widespread application.

[0010] The beneficial effects of this utility model are as follows: This technical solution features universal rollers on the inner side of the moving body facing the rail, which conform to the rail for stable and smooth movement. The hand-operated push rod connects to the moving body, facilitating operator movement along the rail to simulate the action of a train wheelset passing the wheel sensor. The push rod also allows for operator control of the simulation process. Furthermore, a simulated wheelset is located on one side of the moving body; as the body moves along the rail using the push rod, the simulated wheelset triggers the wheel sensor located on the same side of the rail. The overall structure is simple, practical, and easy to operate, efficiently completing wheel sensor testing, improving testing efficiency and accuracy, and ensuring the reliable operation of rail transit equipment. In summary, this technical solution effectively triggers the wheel sensor by simulating a train wheel sliding over it, providing a realistic testing scenario and enabling convenient and stable simulation of a train wheelset passing the wheel sensor. This provides reliable conditions for sensor testing and improves testing efficiency and accuracy. Attached Figure Description
