Rails are usually long steel components, and their cross-sectional shape is generally in the shape of an I-beam, which can provide good bending resistance. For example, on high-speed railways, the train speed is fast and the load is large, so the rails need to have higher strength and stability, and are generally made of high-strength alloy steel, such as steel containing alloy elements such as manganese and chromium. The dimensions of the rails mainly include rail height, rail head width, rail bottom width and rail waist thickness, etc. The heavier the rail, the more train loads it can usually bear. Railway staff need to regularly inspect the rails to check whether there are defects such as wear and cracks on the rail surface; The track inspection vehicle is an important device for detecting the flatness of railway rails. It is widely used in the regular inspection of various railway lines such as main line railways and high-speed railways. It can detect railway tracks with a long mileage at normal running speed, and can quickly obtain a large amount of track geometric data, providing a scientific basis for the maintenance of railway lines. At the same time, the track inspection vehicle is usually equipped with a high-precision sensor system, including an inertial measurement unit, a laser displacement sensor, etc. When the track inspection vehicle runs on the railway at a certain speed, the laser displacement sensor installed at the bottom of the vehicle near the rail emits a laser beam to the rail surface, and then receives the reflected light.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figure 1-6, the present invention provides a technical solution: a railway rail flatness patrol detection device and method, including a self-running trolley 10, a shock absorber 20, a laser displacement sensor 30, a connecting plate 40, a cleaning roller 401, a chute 402, a magnetic slider 403, a lubricating oil tank 404, a telescopic tube 405, a solenoid valve I 406, a storage chamber 50, a pipeline 501 and a solenoid valve II 502; This railway rail flatness patrol detection device facilitates the cleaning and lubrication of the railway rail surface. The specific implementation method is as follows: A shock absorber 20 is fixedly connected to the surface of the self-running trolley 10, and a laser displacement sensor 30 is installed on the surface of the shock absorber 20. Chutes 402 are symmetrically arranged at the bottom of the self-running trolley 10, and two groups of magnetic sliders 403 are symmetrically installed inside the chutes 402. The bottoms of the two groups of magnetic sliders 403 are connected to a connecting plate 40, and cleaning rollers 401 are symmetrically arranged on the surface of the connecting plate 40. Lubricating oil tanks 404 are symmetrically installed on the surface of the self-running trolley 10, and a telescopic tube 405 is connected to the bottom of the lubricating oil tank 404. The telescopic tube 405 passes through the self-running trolley 10 and is connected to the connecting plate 40. A solenoid valve I 406 is arranged on the surface of the telescopic tube 405. A storage chamber 50 is fixedly connected to the surface of the self-running trolley 10, and a pipeline 501 is installed on the surface of the storage chamber 50, and a solenoid valve II 502 is installed inside the pipeline 501. The cross-section of the chute 402 is set as a T-shaped structure, and the magnetic slider 403 is embedded inside the T-shaped structure of the chute 402. And there is a magnetic connection between the chute 402 and the magnetic slider 403, and a sliding connection between the chute 402 and the magnetic slider 403. And the magnetic sliders 403 are symmetrically arranged on both sides of the shock absorber 20. The telescopic tube 405 is arranged inside the connecting plate 40, and the telescopic tube 405 is arranged between the front and rear two cleaning rollers 401. And the cross-section of the cleaning roller 401 is set as an I-shaped structure. The connecting plates 40 are symmetrically arranged on both sides of the shock absorber 20. There is a sliding connection between the connecting plate 40 and the self-running trolley 10, and a rotational connection between the cleaning roller 401 and the connecting plate 40. The end of the pipeline 501 is arranged outside the self-running trolley 10, and there is an alternating arrangement between the self-running trolley 10 and the pipeline 501. The lubricating oil tanks 404 are symmetrically arranged on both sides of the storage chamber 50, and the telescopic tube 405 is communicated with the lubricating oil tank 404. The telescopic tube 405 is made of a flexible material.
[0023] The handheld cleaning roller 401 moves, causing the cleaning roller 401 to drive the connecting plate 40 to move. At this time, the connecting plate 40 drives the magnetic slider 403 to move. At this time, the magnetic slider 403 slides inside the chute 402, and the magnetic slider 403 slides along the T-shaped chute inside the chute 402. The magnetic slider 403 drives the connecting plate 40 to move, causing the connecting plate 40 to drive the end of the telescopic tube 405 to move. At this time, the connecting plate 40 drives the cleaning roller 401 to move, and the cleaning roller 401 moves to the distance between the railway rails. The self-running trolley 10 will be placed, and the self-running trolley 10 will be placed on the ground. At this time, the cleaning roller 401 can be placed outside the railway rails, and at the same time, the end of the telescopic tube 405 moves above the railway rails. The self-running trolley 10 moves, and at the same time, the solenoid valve 406 is opened. At this time, the self-running trolley 10 drives the chute 402 to move, causing the chute 402 to drive the magnetic slider 403 to move, and the magnetic slider 403 drives the connecting plate 40 to move. At this time, due to the friction between the cleaning roller 401 and the railway rails, the connecting plate 40 and the cleaning roller 401 rotate. At this time, the cleaning roller 401 rotates inside the connecting plate 40. At this time, the cleaning roller 401 on the front side of the telescopic tube 405 can clean the surface of the railway rails, and the dust on the surface of the railway rails can be swept off. The solenoid valve 406 loses its closing effect on the telescopic tube 405. At this time, the lubricating oil inside the lubricating oil tank 404 enters the telescopic tube 405 and falls on the surface of the railway rails through the telescopic tube 405. At this time, the cleaning roller 401 on the rear side of the telescopic tube 405 can apply the lubricating oil to maintain the surface of the railway rails.
[0024] This method for the circuit inspection of the flatness of railway rails can mark the positions with abnormal data, which is convenient for finding them. The specific implementation method is as follows: S1: The laser displacement sensor 30 can detect the railway rails, and at the same time, the laser displacement sensor 30 transmits the data through data transmission to the inside of the data analysis. S2: The data analysis can test and detect the data. Through data analysis, calculations and analyses are carried out to detect whether the data of the railway rails is qualified. At this time, the data analysis transmits the data to the information storage. S3: When the data analysis detects that the data of the railway rails is abnormal, it transmits the data to the control device. At this time, the control device can control the solenoid valve 502 to open. The solenoid valve 502 opens the storage cavity 50, causing the powder inside the storage cavity 50 to fall, and marks the position with the powder. At the same time, the solenoid valve 502 can control the alarm near the railway rails with abnormal data to turn on. S4: At this time, the powder falling from the storage cavity 50 can prompt the maintenance personnel of the maintenance position. At the same time, the alarm can remind the maintenance personnel of the detection area. After the maintenance is completed, the alarm can be manually turned off.
[0025] The laser displacement sensor 30 can detect the data of the railway rail. At the same time, the laser displacement sensor 30 can transmit the data to the internal data analysis. At this time, the data analysis can quickly compare and analyze the data, check the data of the railway rail at this place, and analyze whether the data is qualified. The data analysis can store the detected data information internally, store the data through information storage, and when the data analysis detects that the data is unqualified, it means that the flatness of the railway rail at this place is unqualified. At this time, the data analysis can transmit the data to the inside of the control device, and the control device can control the solenoid valve two 502 to open. At this time, the solenoid valve two 502 loses the blockage of the pipeline 501, so that the powder in the storage cavity 50 enters the inside of the pipeline 501 by its own weight, discharges the powder through the pipeline 501, makes the powder fall on the ground, marks the abnormal railway rail, and at the same time the control device can control the alarms on both sides before and after the railway rail to open, which can summarize the position of the railway rail and facilitate the maintenance personnel to confirm the maintenance position.
[0026] In S1, when the self-running trolley 10 moves forward, the laser displacement sensor 30 can detect the surface of the railway rail passing by; When the self-running trolley 10 is running, the self-running trolley 10 drives the position of the laser displacement sensor 30 to move. At this time, the laser displacement sensor 30 detects and senses the surface of the railway rail.
[0027] In S2, the information data is recorded through information storage, and at the same time, the information data can store abnormal and correct data at the same time; The information storage can store the data, which is convenient for subsequent inspection and verification of the situation at this place.
[0028] In S3, the alarms are installed along the railway rail. When the data of the railway rail is abnormal, the control device controls the alarms on both sides of the abnormal data to open through the data; The alarms can mark the position of the uneven railway rail, which is convenient for the maintenance personnel to confirm the range of the position with abnormal data and facilitate its maintenance.
[0029] Working principle: When using the railway rail flatness circuit detection equipment and method, the chute 402, magnetic slider 403, lubricating oil tank 404, telescopic pipe 405 and solenoid valve one 406 are set, which is convenient for cleaning and lubricating the surface of the railway rail. The storage cavity 50, pipeline 501 and solenoid valve two 502 are set, which can mark the position with abnormal data, facilitate finding it, and increase the overall practicability.
