[0038] The concept, specific structure and generated technical effects of the present application will be described clearly and completely in combination with the embodiments and the drawings below, so as to fully understand the purpose, scheme and effects of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The same reference signs used in the drawings indicate the same or similar parts.

[0039] It should be noted that, unless otherwise specified, when a certain feature is referred to as being "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. In addition, the up, down, left, right and other descriptions used in the present application are only relative to the mutual position relationship of the components of the present application in the drawings.

[0040] Reference Figures 1 to 5The wheel shaft position sensor measurement and detection tool comprises a hand-held frame 1, a measurement scale 3, an inductive plate 4, a level 2 and two leveling screws 6 installed on the hand-held frame 1, the upper surface and the lower surface of the level 2 are parallel to the horizontal plane, the upper surface is provided with a horizontal bubble device 7, the two leveling screws 6 are vertically and spacedly installed on the level 2, and the measurement scale 3 is vertically arranged and perpendicular to the level 2. When the lower surface of the level 2 is in a horizontal state and in contact with the upper surface of the steel rail, the measurement scale 3 can be moved up and down relative to the hand-held frame 1 or the level 2 so that the lower surface can be closely attached to the upper end surface of the sensor, and the 0 scale on the measurement scale 3 is located at the bottom end and below the level 2. The inductive plate 4 is slidably installed on the measurement scale 3, and the distance between the center of the inductive plate 4 and the bottom end of the measurement scale 3 can be 15-25 mm. The inductive plate 4 is used for testing the state of the wheel shaft position sensor. Since the installation height of the wheel shaft position sensor is 40±2 mm, the main body of the measurement scale 3 contains scale values of 0-120 mm. The measurement of the installation height of the wheel shaft position sensor and the detection of whether it can work normally in the present scheme can ensure that the wheel shaft position sensor can work normally when the wheel passes, and can avoid damage or non-triggering of the sensor.

[0041] Specifically, the level 2 can be made of a magnetic material, which can be preferably a magnetic wear-resistant material. In use, the level 2 is attracted to the steel rail by magnetic force, and needs to be adjusted to a horizontal state before measurement and detection. The level 2 can be adjusted to a horizontal state by manually rotating the leveling screw 6 so that the water bubble in the horizontal bubble device 7 above the level 2 is located in the middle of the device.

[0042] The inductive plate 4 is fixed at a proper scale of the measurement scale so as to detect whether the wheel shaft position sensor can work normally while measuring the installation height of the wheel shaft position sensor. Since the measurement distance for measuring the installation height of the wheel shaft position sensor is the vertical distance of the space from the rail surface to the upper surface of the sensor, the rail surface is not a plane, and the measurement reading needs to correspond to the highest point of the rail surface. A single tool cannot achieve accurate measurement, and multiple tools need to be used to complete the measurement, which is difficult for one person to complete, and there is a large error in the use of multiple tools. The detection of whether the wheel shaft position sensor works normally needs to test at a position 20 mm above the sensor, and a ruler is used to measure the 20 mm position in conventional measurement, and then the inductive plate 4 is held to the 20 mm position, and another person observes the indicator light of the sensor. Due to the difficulty in keeping the hand-held position unchanged for a long time, there is also a large measurement error, and two people are needed to complete the measurement. The wheel shaft position sensor measurement and detection tool of the present scheme can achieve direct clamping measurement, and the measurement error is 1 cm 2The inductive plate 4 is fixed at a proper scale position of the measuring scale, so that when measuring the installation height of the wheel axle position sensor, the inductive plate can be inducted by the wheel axle position sensor, the position adjustment of the inductive plate 4 by the operator can be reduced, the work efficiency and the measuring accuracy can be improved.

[0043] When the horizontal ruler 2 is horizontally placed above the rail and the bottom surface is close to the upper surface of the rail, and the 0 scale at the bottom end of the measuring scale 3 is close to the upper surface of the sensor, at this time, the scale on the measuring scale 3 corresponding to the bottom surface of the horizontal ruler 2 is the installation height of the wheel axle position sensor. Since the wheel axle position sensors are usually installed at both ends of the track, when the wheel passes above the wheel axle position sensor, the sensor will receive the signal and send it to the online monitoring device, so as to start the online data acquisition, and at the same time, the indicator light on the sensor is on. The inductive plate 4 can simulate the appearance of the wheel, and the wheel axle position sensor can turn on the indicator light due to the induction of the inductive plate 4. Whether the wheel axle position sensor is working normally can be judged by observing whether the indicator light on the wheel axle position sensor is normally on, so that the state of the wheel position sensor can be tested.

[0044] The scheme can be used for measuring the installation height of the wheel position sensor and testing the state of the wheel position sensor, and solves the problems that a large number of tools and devices need to be carried for the above measurement and testing, the measurement takes a long time, and the maintenance is inconvenient. By using the wheel axle position sensor measurement and detection tool of the scheme, the measurement error can be reduced, the reliability of the measurement can be improved, at the same time, the tool is simple to operate, convenient to maintain, and the staff can quickly and effectively master the requirements of the wheel position sensor parameters, and the fault maintenance processing level and ability are improved.
