Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for rail vehicle maintenance, and in particular to a height measuring device for a rail vehicle phase-crossing induction receiver. Background Technology

[0002] Wheel wear is a common and significant problem in the operation and maintenance of rail vehicles. As wheels wear down, the overall height of the carriage gradually decreases. The phase-splitting sensors on rail vehicles have strict requirements regarding their installation height and position: they must be maintained within the range of 110-130mm from the rail surface and within 300±20mm from the center of the rail. To ensure safe and stable operation and meet these parameter requirements, maintenance personnel must periodically measure the height of the phase-splitting sensor receivers according to the vehicle's operation and maintenance cycle and make necessary adjustments based on the measurement results.

[0003] However, in actual operation, this work faces many difficulties. Since the phase sensor and the rail are not on the same vertical plane, various types of measuring tools and complex tooling equipment are required during installation and measurement. The use of different tools not only increases the complexity of the operation, but also makes it difficult to ensure the accuracy of dimensional measurements due to human factors, tool precision and other reasons. At the same time, the complicated operation process also greatly reduces the installation efficiency and increases the time and cost of maintenance work. Utility Model Content

[0020] The embodiments of the present utility model are described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0021] In the description of the present utility model, it should be understood that when it comes to orientation descriptions, such as up, down, etc., the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0022] In the description of the present utility model, "plural" refers to more than two. If there is a description of first and second, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or the sequence relationship of the indicated technical features.

[0023] In the description of the present utility model, unless otherwise clearly defined, terms such as "set", "install", "connect", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0024] Refer to Figure 1 、 Figure 2 , a height measurement device for an on-load tap-changer induction receiver of a rail vehicle, which includes a fixing frame 1 inserted on the rail. The fixing frame 1 is a "冂"-shaped structure adapted to the rail. A longitudinal measuring scale 2 is fixedly connected by welding at the top of the fixing frame 1. A transverse measuring scale 3 is slidably connected to the surface of the longitudinal measuring scale 2. The transverse measuring scale 3 includes a slider 31 sleeved on the longitudinal measuring scale 2. One side of the slider 31 is fixedly connected with a metal scale 32. A level 33 is fixedly connected to the bottom end of the metal scale 32. For the convenience of observation, the level 33 is a horizontal bubble level.

[0025] In order to be able to limit and fix the transverse measuring scale 3 well, a limiting magnet 4 for supporting the slider 31 is provided on the longitudinal measuring scale 2. The limiting magnet 4 is in two pieces and is symmetrically arranged on both sides of the longitudinal measuring scale 2 respectively. This design effectively improves the stability during measurement and ensures the accuracy and reliability of the measurement data.

[0026] For the convenience of measurement, scale marks 21 are etched on the surface of the longitudinal measuring scale 2. The length of the longitudinal measuring scale 2 is 130 mm. Scale 35 is etched on the metal scale 32. The length of the metal scale 32 is 320 mm.

[0027] In order to prevent the slider 31 from sliding out of the longitudinal measuring scale 2, a limiting block 22 is provided at the top of the longitudinal measuring scale 2.

[0028] During measurement, the horizontal measuring ruler 3 is slid along the surface of the vertical measuring ruler 2 using the slider 31 until the vertical measuring ruler 2 contacts the center of the lower surface of the sensor receiver. During this process, it is necessary to observe whether the level 33 is in a horizontal state. Then, the values ​​of the horizontal measuring ruler 3 and the vertical measuring ruler 2 are read. During the measurement process, when the horizontal measuring ruler 3 contacts the center of the lower surface of the sensor receiver, two sets of limiting magnets 4 are magnetically attracted to both sides of the horizontal measuring ruler 3. The two sets of limiting magnets 4 support the bottom of the slider 31, which plays a limiting role and prevents the slider 31 from sliding downward under the action of gravity, thereby reducing measurement error.

[0029] This device can effectively improve the installation dimensions of the phase-separation sensor receiver for rail vehicles. The longitudinal measuring ruler 2 can quickly measure the height of the sensor receiver from the rail, and the transverse measuring ruler 3 can quickly measure the transverse distance of the sensor receiver from the rail. It is simple and convenient to use. The longitudinal measuring ruler 2 is also equipped with a limit magnet 4, which can effectively limit and fix the transverse measuring ruler 3, effectively improving the stability during measurement and ensuring accurate and reliable measurement data, thus providing a stronger guarantee for the safe operation of rail vehicles.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
