Description

Technical Field

[0001] This utility model relates to the field of carbon skateboard testing technology, and more specifically, to a multi-point rail transit carbon skateboard wear testing device. Background Technology

[0002] Carbon sliding contactors are crucial components for electric locomotives or electric multiple units (EMUs) to obtain electrical energy from the overhead contact line. They are typically installed at the top of the pantograph, making direct contact with the contact line to transmit power. Because carbon sliding contactors are in constant contact with the contact line, they require regular inspection to prevent equipment damage and economic losses.

[0003] Current carbon skateboard wear detection methods mostly rely on manual inspection or single-point laser ranging technology, which has the following drawbacks:

[0004] 1. Manual measurement is inefficient, inaccurate, and cannot achieve dynamic monitoring;

[0005] 2. Single-point laser sensors cannot cover the entire curved surface of the carbon skateboard, which can easily lead to data blind spots;

[0006] 3. Traditional linear array layouts cannot match the curved surface features of carbon skateboards, resulting in data distortion. Utility Model Content

[0007] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a multi-point rail transit carbon slide plate wear detection device.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A multi-point track transit carbon skateboard wear detection device includes a controller, a display electrically connected to the controller, and a laser sensor;

[0010] It also includes a preset plate assembly and two independently set fixing components. The preset plate assembly matches the carbon slide structure, and the positions of the preset plate assembly and the carbon slide are fixed by the two sets of fixing components.

[0011] Among them, there are multiple laser sensors, which are arranged in an array at equal intervals along the arc trajectory of the preset plate assembly, so that the emission axis of the laser sensor matches the curvature of the carbon slide plate surface.

[0012] Furthermore, there are eight laser sensors, and the distance between two adjacent laser sensors is 100mm, which is consistent with the length of the working area of ​​the carbon slide plate.

[0013] Furthermore, the length of the preset plate assembly is the same as the length of the carbon slide plate and is integrally formed, and is made of aluminum alloy.

[0014] Furthermore, the preset plate assembly includes a top plate, side plates, and a bottom plate; the top plate is arc-shaped and each end is connected to a side plate, and each side plate has a bottom plate at its bottom that contacts the upper surface of the carbon slide plate.

[0015] Furthermore, the curvature of the top plate is consistent with the curvature of the working area of ​​the carbon slide plate.

[0016] Furthermore, the base plate is in close contact with the carbon sliding plate surface.

[0017] Furthermore, the fixing component includes a mounting base, a fixing bolt, and a pressure seat; the mounting base is vertically provided with a fixing bolt on its top, and the fixing bolt is connected to a pressure seat made of rubber.

[0018] Furthermore, the bottom surface of the pressure seat is flat, and the bottom surface of the inner cavity of the pressure seat is an arc surface that fits against the bottom surface of the carbon slide plate.

[0019] Furthermore, the fixing assembly also includes a bearing, and the bottom end of the fixing bolt is connected to the pressure seat through the bearing.

[0020] Furthermore, the fixing component also includes a limiting seat, which is disposed on the mounting base and integrally formed with the mounting base to form a limiting cavity on the back of the inner cavity of the limiting seat that is consistent with the width of the carbon slide plate.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This invention utilizes a controller, display, laser sensor, preset plate assembly, and fixing assembly to work together. This allows the laser sensor to be distributed in a multi-point array, with the length of the working area of ​​the carbon slide plate being consistent with its length. This ensures comprehensive coverage of the main working area of ​​the carbon slide plate. Furthermore, the laser sensor's emission axis matches the curvature of the carbon slide plate surface, making the laser beam perpendicular to the surface. This not only enables dynamic measurement of the wear on the carbon slide plate surface but also greatly improves measurement accuracy, providing reliable data support for the maintenance and replacement of the carbon slide plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0029] A multi-point rail transit carbon skateboard wear detection device, as shown in the attached document. Figure 1 As shown, it includes a controller 1, a display 2 electrically connected to the controller 1, and laser sensors 3, wherein there are 8 laser sensors 3;

[0030] In addition, it also includes a preset plate assembly 4, which matches the carbon skateboard structure; among them, eight laser sensors 3 are arranged in an array at equal intervals along the arc trajectory of the preset plate assembly 4, so that the emission axis of the laser sensor 3 matches the curvature of the carbon skateboard surface.

[0031] In addition, it also includes a fixing component 5, which consists of two sets and is set independently, and is used to fix the position of the preset plate component 4 and the carbon slide plate.

[0032] In its specific implementation, this utility model mainly consists of a controller 1, a display 2, a laser sensor 3, a preset plate assembly 4, and fixing components 5. The controller 1 is electrically connected to the display 2 and the laser sensor 3 to control and process the entire detection process and display the results on the display 2. The preset plate assembly 4 matches the carbon slide plate structure and provides an installation reference for the laser sensor 3, ensuring that the laser sensor 3 can accurately measure the surface of the carbon slide plate. Subsequently, the preset plate assembly 4 is connected to the carbon slide plate through two sets of fixing components 5 to ensure that the relative position of the preset plate assembly 4 and the carbon slide plate remains fixed during the measurement process. The eight laser sensors 3 are equidistant along the arc-shaped trajectory of the preset plate assembly 4. The laser sensors are arranged in an array with a spacing of 100mm between adjacent laser sensors 3 and a total length of 800mm, which is consistent with the working area of ​​the carbon slide plate. This allows the main working area of ​​the carbon slide plate to be covered, ensuring comprehensive measurement of the wear on the carbon slide plate surface. At the same time, the emission axis of the laser sensor 3 is matched with the curvature of the carbon slide plate surface, which enables the laser beam to be perpendicular to the carbon slide plate surface, improving the accuracy of the measurement. Through synchronous trigger scanning, each laser sensor 3 measures the carbon slide plate surface simultaneously, realizing full-coverage dynamic measurement of the wear on the carbon slide plate surface. When there is wear on the carbon slide plate surface, the distance measured by the laser sensor 3 will change. Based on the laser ranging principle, the wear at different locations on the carbon slide plate surface can be calculated.

[0033] For the above scheme, please refer to the appendix. Figure 1 As shown, the preset plate assembly 4 is integrally formed with the same length as the carbon slide plate and is made of aluminum alloy to better fit with the carbon slide plate and ensure the accuracy and stability of the measurement. The preset plate assembly 4 includes a top plate 41, side plates 42, and a bottom plate 43. The top plate 41 is arc-shaped to match the shape of the working surface of the carbon slide plate, providing a mounting plane for the laser sensor 3 with the same curvature as the carbon slide plate surface. When the laser sensor 3 is mounted on the top plate 41, its emission axis can be perpendicular to the carbon slide plate surface or maintain a specific angle relationship, thereby ensuring that the laser beam can accurately irradiate the carbon slide plate surface, achieving accurate distance measurement and thus accurately obtaining the wear condition of the carbon slide plate surface. Each end of the top plate 41 is connected to a side plate 42, and each side plate 42 has a bottom plate 43 that contacts the upper surface of the carbon slide plate. The curvature of the top plate 41 is consistent with the curvature of the working area of ​​the carbon slide plate, and the bottom plate 43 is in close contact with the carbon slide plate surface.

[0034] For the above scheme, please refer to the appendix. Figure 2 As shown, the fixing component 5 includes a mounting base 51, a fixing bolt 52, and a pressure seat 53; the mounting base 51 is vertically provided with a fixing bolt 52 on its top, and the fixing bolt 52 is connected to a pressure seat 53 made of rubber; the bottom surface of the pressure seat 53 is flat, and the bottom surface of the inner cavity of the pressure seat 53 is an arc surface that fits against the bottom surface of the carbon slide plate.

[0035] The plan refers to the appendix. Figure 2 As shown, the fixing component 5 also includes a bearing 54, and the bottom end of the fixing bolt 52 is connected to the pressure seat 53 through the bearing 54. When the fixing bolt 52 is tightened, the rotational motion can be converted into a smooth vertical downward movement of the pressure seat 53 through the bearing 54, so that the pressure seat 53 will not generate a large friction on the preset plate assembly 4, thereby reducing the wear of the pressure seat 53 and the preset plate assembly 4.

[0036] The plan refers to the appendix. Figure 3 and attached Figure 4 As shown, the fixing component 5 also includes a limiting seat 55, which is disposed on the mounting base 51 and integrally formed with the mounting base 51, so as to form a limiting cavity on the back of the inner cavity of the limiting seat 55 that is consistent with the width of the carbon slide plate; so as to provide precise lateral positioning for the carbon slide plate, ensuring that the carbon slide plate can be accurately placed in the preset position during installation, ensuring the positional accuracy of the carbon slide plate, and maintaining the correct relative positional relationship between it and the preset plate component 4 and the laser sensor 3, thereby improving the accuracy of wear detection.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
