[0029] In order to make the personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.
[0030] According to the embodiment of the present application, a rail wear measuring device is provided, please refer to Figures 1 to 7The rail wear measuring device comprises a plurality of measuring components 1, each of which is used for measuring the top edge, side edge and fat edge of the rail head, and is provided with a scale 11; a fixed body 2 is provided with a positioning mark 3, is used for clamping on the outer contour of the rail, and provides a plurality of fixed ports 21 for installing the measuring components 1, and each measuring component 1 is movably arranged in the corresponding fixed port 21; the measuring component 1 in each fixed port 21 is moved so that the end of the measuring component 1 abuts against the top edge, side edge and fat edge of the rail head respectively, and the wear values of the top edge and side edge and the protrusion degree of the fat edge of the rail head are obtained by reading the numerical value of the relative position of the scale 11 and the positioning mark 3. Each measuring component 1 is movable in the fixed port 21 of the fixed body 2, so as to abut against the corresponding top edge, side edge and fat edge of the rail head, and according to the numerical value of the relative position of the scale 11 and the positioning mark 3, the user can quickly and accurately obtain the wear value or the protrusion degree, thereby avoiding the repeated measurement and unnecessary time waste in the traditional method, and greatly improving the measuring efficiency. Moreover, the measurement of the top edge, side edge and fat edge of the rail head can be completed without the cooperation of multiple persons, thereby significantly reducing the situation that multiple persons need to operate simultaneously in the traditional measurement mode, and reducing the labor cost and operation complexity. The rail wear measuring device of the embodiment solves the technical problems of time-consuming and labor-consuming in the traditional measurement in the related art.
[0031] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the rail wear measuring device includes three measuring components 1 and three fixing ports 21. The three fixing ports 21 are respectively arranged along the sides and top of the fixing body 2. Each measuring component 1 is disposed in a corresponding fixing port 21, corresponding to the measurement of the top edge, side edge, and thick edge of the rail head. A first fixing plate 22 is provided on the side of each fixing port 21 near the rail head. The two ends of the first fixing plate 22 are fixed to the fixing body 2, and the measuring component 1 is movable on the first fixing plate 22. The measuring components are a top edge scale 13, a side edge scale 14, and a thick edge scale 15, specifically corresponding to the top edge, side edge, and thick edge of the rail, ensuring accurate measurement of wear at different locations. Each fixing port 21 is provided with a first fixing plate 22, on which the measuring component 1 is movably mounted, providing a stable measuring platform for the measuring component 1. Three fixing ports 21 are respectively located on the left, right, and top of the fixing body 2. The top edge scale 13, side edge scale 14, and thick edge scale 15 are respectively located in the three fixing ports 21. The operating steps of the rail wear measuring device in this embodiment are as follows: First, use the top edge scale 13 and side edge scale 14 to measure the wear value of the top edge and side edge of the rail head. Since the thick edge is at the intersection of the top edge and side edge, after measuring the top edge and side edge, rotate the fixing body 2 180° to rotate the thick edge scale 15 on the other side to the side edge, and measure the degree of protrusion of the thick edge above the side edge (e.g., Figure 2 and Figure 3 (As shown). Measurements can be completed simply by moving the measuring component 1, without the need for personnel to hold multiple measuring components 1 or make complex adjustments, thus improving ease of use.
[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment of the rail wear measuring device, a gap is left between the first fixing plate 22 and the fixing body 2. A second fixing plate 23 is connected within this gap, and both ends of the second fixing plate 23 are connected to both ends of the measuring component 1, thereby allowing the measuring component 1 to move relative to the first fixing plate 22. The gap between the first fixing plate 22 and the fixing body 2 provides space for the installation of the second fixing plate 23. The second fixing plate 23 is connected to both ends of the measuring component 1, forming a movable connection structure. Due to the connection design between the measuring component 1 and the second fixing plate 23, the measuring component 1 can slide freely on the first fixing plate 22, allowing the measuring component to be flexibly adjusted relative to the first fixing plate 22 of the fixing body 2. The measuring component 1 can be connected to the fixing body 2 and can also move relative to the fixing body 2, thereby accurately moving the end of the scale to the contact position of the top edge, side edge, and thick edge of the rail head.
[0033] See Figure 5In this embodiment of the rail wear measuring device, the positioning mark 3 is set on the center line of the first fixed plate 22. The design of the center line also makes the relative positional relationship between the positioning mark 3 and the scale 11 of the measuring component 1 clearer.
[0034] See Figure 5 , Figure 6 and Figure 7 In this embodiment of the rail wear measuring device, the positioning mark 3 is a positioning line 31. The extension direction of the positioning line 31 is parallel to the scale 11, making it easier for the user to align and compare when reading the measured values. This design reduces reading errors caused by the angle of view or the positional offset of the measuring components, thereby improving the accuracy of the measurement.
[0035] See Figure 1 , Figure 5 , Figure 6 and Figure 7 In this embodiment of the rail wear measuring device, the measuring component 1 is also equipped with an over-limit indicator 12. When the over-limit indicator 12 is aligned with the positioning line 31, it indicates that the rail wear has reached or exceeded the safety limit. The over-limit indicator 12 is a red-marked scale line. The red-marked over-limit indicator 12 is more visually conspicuous and can attract the user's special attention. When the red-marked scale line is aligned with the positioning line 31, the user can immediately realize that the rail wear has reached or exceeded the predetermined safety limit, thereby taking necessary maintenance measures in a timely manner to prevent potential safety hazards.
[0036] See Figure 1 and Figure 2 In this embodiment of the rail wear measuring device, two locking plates 24 are respectively provided on both sides of the bottom of the fixed body 2. The two locking plates 24 are used to increase the contact area with the bottom of the rail, thereby increasing the connection between the fixed body 2 and the rail. The setting of the two locking plates 24 significantly increases the contact area between the fixed body 2 and the bottom of the rail. The fixed body 2 can fit more tightly on the rail, and can maintain a good connection even when there are minor unevenness or deformation on the rail surface. This design makes the fixed body 2 more stable when it is locked onto the outer contour of the rail, and it is not easy to loosen or shift due to external force or vibration. Therefore, the device can maintain higher stability during wear measurement, thereby improving the accuracy of the measurement.
[0037] See Figure 1 and Figure 2 In this embodiment, the rail wear measuring device has two detachable clamping plates 24, which facilitates timely replacement with clamping plates that are more compatible with the bottom outline of the rail, thus improving the versatility and adaptability of the device.
[0038] See Figure 1 , Figure 2 , Figure 3and Figure 4 In this embodiment of the rail wear measuring device, the top of the fixed body 2 is also provided with a handle hole 25, which is used to lift and put down the fixed body 2 for easy handling.
