Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to a rail lubrication spraying system and a train. Background Technology

[0002] In rail transit, when trains travel on curved sections, the interaction between the wheel and rail intensifies due to changes in the track and the superelevation of the outer rail. This can easily lead to wheel flange contact, resulting in side wear of the rail. Side wear of the rail accelerates rail damage, shortens its service life, and increases wheel-rail noise.

[0003] Currently, there are many solutions to the problem of rail side wear on curved sections. In practical applications, rail lubrication is commonly used for rail side wear on curved sections. This method involves installing a lubrication device next to the main rail, applying lubricant to the wheel area, and then using the wheel to carry the lubricant to the curved section rail, thereby lubricating the rail side and reducing wear on the side of the curved rail. However, in actual lines, the location of rail side wear on curved sections may vary. Current lubrication methods may result in ineffective lubrication of the worn rails or over-lubrication in some areas, leading to low accuracy. Utility Model Content

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] Please see Figures 1-2 , Figure 1 A schematic diagram of the structure of the first embodiment of the rail lubrication spraying system of this utility model is shown. Figure 2 A schematic diagram of the wheel-rail contact structure in the rail lubrication spraying system of this utility model is shown, as follows: Figure 1 As shown, the track lubrication spraying system includes an image acquisition device, an image processing device, a main control module, and a spraying device installed on the train.

[0029] The image acquisition device includes at least two devices, which can be cameras or industrial cameras, or other devices capable of acquiring images. One image acquisition device is installed on the front or rear side of each of the two parallel wheels of the train, with the front or rear side of the wheel corresponding to the direction of train travel. The image acquisition device acquires wheel-rail images in real time or at regular intervals when the train is traveling on curved sections. The wheel-rail images are images of the wheel-rail contact position directly in front of or behind the wheel.

[0030] The image processing device is connected to both the image acquisition device and the main control module. The image acquisition device sends the acquired wheel-rail images to the image processing device. The image processing device detects whether the rail has experienced side wear based on the wheel-rail images.

[0031] The image processing device analyzes the wheel-rail image and determines whether side wear has occurred on the rail based on the analysis results. If so, it sends a side wear signal to the main control module. The image processing device first preprocesses the wheel-rail image, which may include using filtering techniques to remove noise, identifying image edges, or performing binarization on the noise-removed image. The image processing device then analyzes whether the vertical centerline of the rail and the vertical centerline of the wheel are collinear in the preprocessed wheel-rail image. If they are collinear, side wear has occurred; if they are not collinear, no side wear has occurred. Figure 2 As shown, an image acquisition device can capture wheel-rail images of the rail in contact with the wheel on either the front or rear side. By analyzing whether the vertical centerline of the rail and the vertical centerline of the wheel are aligned, it can be determined whether side wear has occurred on the rail. This embodiment can clearly, intuitively, and accurately identify whether side wear has occurred on the rail using wheel-rail images of the front or rear side of the wheel.

[0032] The spraying device includes at least one component containing lubricant and is mounted on one side of a train wheel. A main control module is connected to the spraying device; when side wear occurs on the rail, the main control module receives a side wear signal from the image processing device and controls the spraying device to spray lubricant onto the wheel-rail contact point where side wear has occurred.

[0033] In one embodiment, the spraying device includes one unit mounted on the train and positioned between the two wheels. The side-wear signal may include an identifier of an image acquisition device, which is associated with the rotation angle of the spraying device. The main control module triggers the spraying device to rotate based on the side-wear signal, so that the nozzle of the spraying device is directly facing the position where the rail is experiencing side-wear, and sprays lubricant onto the corresponding wheel-rail contact position where side-wear occurs. A motor connected to the main control module may be included, with its shaft connected to the spraying device. The main control module controls the rotation of the motor shaft, thereby causing the spraying device to rotate.

[0034] In other embodiments, the spraying device includes two devices, one located near one wheel and on one side of that wheel, and the other located near another wheel and on one side of that wheel, such that the nozzles of the spraying devices are directly facing the wheel-rail contact point of the corresponding wheel. The side-wear signal may include an identifier of the image acquisition device, which is associated with a corresponding spraying device. The main control module triggers the associated spraying device based on the side-wear signal, causing the spraying device to spray lubricant onto the wheel-rail contact point where side-wear has occurred on the corresponding rail.

[0035] In other embodiments, the spraying apparatus may include three or four, etc., which will not be described in detail here.

[0036] The image acquisition device of this utility model acquires wheel-rail images at the wheel-rail contact position directly in front of or behind the wheels when the train is traveling on a curve. The image processing device detects whether the rail has experienced side wear based on the wheel-rail images. If side wear occurs, the main control module controls the spraying device to spray lubricant onto the wheel-rail contact position where side wear has occurred. The lubricant lubricates the side-wearing position of the rail, effectively preventing further deterioration of the side wear. This embodiment, by controlling the spraying device through the main control module to spray lubricant onto the wheel-rail contact position where side wear has occurred, can automatically and accurately spray lubricant onto the side-wearing position of the rail, saving rail lubrication materials and effectively solving the problem of insufficient or excessive lubrication for rail side wear.

[0037] In one embodiment, such as Figure 2 As shown, the rail lubrication spraying system also includes a mounting bracket, which is mounted on the wheel axle and located on one side of the wheel. The spraying device is mounted on the mounting bracket. Since the wheel axle is stationary relative to the moving train, mounting the bracket on the wheel axle and placing the spraying device on the bracket makes the spraying device more stable and allows for better alignment of the wheel-rail contact position, thus improving spraying accuracy.

[0038] Furthermore, such as Figure 2As shown, the spraying device and mounting brackets consist of four units each. Each of the two parallel wheels of the train has one spraying device and one mounting bracket installed on both the left and right sides. When side friction occurs on one side of the rail, lubricant can be sprayed onto the wheel-rail contact area where side friction occurs using the spraying devices on both sides of that wheel. Compared to using a single spraying device, using two spraying devices simultaneously allows for more thorough lubrication.

[0039] In one embodiment, such as Figure 3 As shown, the rail lubrication spraying system also includes a power component installed on the train. The mounting bracket includes a fixed part and a rotating part that are rotatably connected. The fixed part is connected to the wheel axle, the main control module is connected to the power component, and the rotating shaft of the power component is connected to the rotating part.

[0040] The power component can be a motor, which rotates the rotating part of the mounting bracket, thereby rotating the spraying device. In this embodiment, the image processing device also obtains the location information corresponding to the location of rail side wear based on the wheel-rail image and sends the location information to the main control module. The location of rail side wear includes the inner and outer positions of the rail. The wheel-rail image can identify whether the side wear occurs on the inner or outer position of the rail. The inner side of the rail refers to the side of the rail closer to another rail, and the outer side refers to the side of the rail farther from another rail. When rail side wear occurs, the main control module controls the rotating part of the mounting bracket to rotate according to the location information, thereby adjusting the angle of the spraying device to align with the wheel-rail contact position where rail side wear occurs, thus enabling accurate spraying of lubricant at the wheel-rail contact position where rail side wear occurs.

[0041] Furthermore, such as Figure 4 As shown, the rail lubrication spraying system also includes an accelerometer installed on the train. The accelerometer is connected to the main control module and is used to measure the three-axis acceleration of the train. The accelerometer sends the acceleration data to the main control module, which calculates the train's speed based on the acceleration. The main control module then controls the spraying speed of the spraying device based on the train's speed, and / or controls the distance between the spraying device and the wheel-rail contact points based on the train's speed. In this embodiment, to achieve more uniform lubricant spraying, the spraying speed of the spraying device is controlled according to the train's speed. When the train's speed is higher, the spraying speed of the spraying device increases accordingly; when the train's speed is lower, the spraying speed decreases accordingly, thus ensuring uniform spraying. Furthermore, the distance between the spraying device and the wheel-rail contact points is controlled according to the train's speed. When the train's speed is higher, the distance between the spraying device and the wheel-rail contact points can be closer; when the train's speed is lower, the distance can be farther, thus ensuring uniform spraying.

[0042] Furthermore, such as Figure 5 As shown, the rail lubrication spraying system also includes a gyroscope mounted on the train. The gyroscope is connected to the main control module, which in turn is connected to an image acquisition device. The gyroscope measures the angular velocity of the train body around its vertical axis in real time. The main control module uses this angular velocity to determine whether the train is currently traveling on a curve. If it is, the image acquisition device is triggered to start and acquire wheel-rail images. In this embodiment, the gyroscope accurately identifies curves and triggers the image acquisition device to acquire wheel-rail images on the curve, which is beneficial for accurately identifying rail side wear on curves.

[0043] Furthermore, the aforementioned gyroscope and accelerometer are integrated into the inertial navigation system, which can be a fiber optic inertial navigation system or other types of inertial navigation systems.

[0044] In one embodiment, the rail lubrication spraying system further includes a framework, such as Figure 2 As shown, the two ends of the frame are directly suspended from the two ends of the train's wheel axle. The frame is located above the wheel, and the image acquisition device is mounted on the frame. It is highly stable and located directly in front of and / or behind the wheel, aligned with the wheel-rail contact position directly in front of and / or behind the wheel, so that the image acquisition device can stably and accurately acquire wheel-rail images.

[0045] This utility model embodiment also provides a train equipped with the above-described track lubrication spraying system.
