The controller can control the actions of the driving mechanism and the first cleaning component, and store the detection data of the camera and the detection component.

[0030] In a specific embodiment of the present invention, Figure 2 As shown, the chassis 1 is a U-shaped shell with an opening facing downward, and the driving mechanism includes a motor 3 and rollers 4 symmetrically arranged on both sides of the track 00. The outer wall of the motor 3 is connected to the inner wall of the chassis 1, and the output end of the motor 3 is connected to the main shaft of the roller 4, and the roller 4 is in contact with the top surface of the rail head 01; the camera 2 is correspondingly arranged between the rollers 4 on both sides. Among them, the driving mechanism is four groups, and the four rollers 4 are arranged in two groups at the front and rear parts of the chassis 1, and the two rollers 4 in each group are symmetrically arranged on both sides of the top surface of the rail head 01. During detection, the motor drives the rollers to move along the track, and then drives the trolley to move along the length direction of the track to achieve flaw detection of the track.

[0031] Further optimize the above scheme, such as Figure 2 As shown, buffer components in contact with both sides of the rail head 01 are also provided on the inner walls of both sides of the chassis 1, and the buffer components include a U-shaped clamp 5 and a spring 6. The open side of the U-shaped clamp 5 can wrap the edges of both sides of the rail head 01, and the outer side of the closed end of the U-shaped clamp 5 is connected to the spring 6, and the other end of the spring 6 is connected to the inner wall of the chassis 1. The U-shaped clamp can guide the chassis, and the spring can reduce the shock of the chassis, ensuring the working stability of the internal camera and detection components.

[0032] In a specific embodiment of the present invention, Figure 2 , 3 As shown, the detection assembly includes an ultrasonic generator 7 and an ultrasonic receiver 8, which are respectively arranged on both sides of the waist 02 of the track 00.

The ultrasonic generator and ultrasonic receiver are relatively installed in the protective nets on both sides, which can enhance the propagation effect of ultrasonic waves, and prevent dust or other impurities from entering the generator and receiver, thereby protecting the ultrasonic generator and ultrasonic receiver. This structure can be used to perform flaw detection on the waist of the track by ultrasonic waves.

[0033] When designing specifically, Figure 1 , 4 As shown, the first cleaning assembly includes a roller brush 11 and a blower (not shown), the blower is connected to the chassis 1, the blower is connected to the inner cavity of the roller brush 11 through the air duct and the air duct in the connecting frame 12, the roller brush 11 is connected to the side wall of the chassis 1 through the connecting frame 12, and the length of the roller brush 11 is consistent with the width of the rail head 01. When the chassis travels along the track, the blower is started to make the roller brush rotate at high speed, and the roller brush is used to clean the top surface of the rail head to prevent impurities on the surface of the rail head from affecting the camera shooting.

[0034] Further optimize the above scheme, such as Figure 4-6 As shown, a scraper 13 is also provided at the front end of the chassis 1, and the scraper 13 can be covered on both sides of the rail head 01 and the rail waist 02.

During the running of the chassis, the dust attached to the track surface is initially cleaned with the help of the scraper. When encountering large impurities, the spring can play a buffering role.

[0035] In addition, an infrared sensor can be installed at the front end of the chassis. When the infrared sensor detects a large obstacle on the track, it immediately sends an alarm signal to the controller. The controller controls the motor to stop and the trolley stops moving to avoid damage to the trolley.

[0036] During specific production, a scraper 17 is provided at the front end of the scraper 13, and multiple scrapers 17 are spaced apart on the inner wall at the top of the scraper 13. With the help of the scraper 17, impurities on the surface of the rail head 01 and both sides of the rail waist 02 can be preliminarily removed, reducing the workload of subsequent cleaning.

[0037] In a specific embodiment of the present invention, Figure 1 As shown, the second cleaning component includes two brushes 16, and the two brushes 16 are symmetrically arranged on the inner walls on both sides of the chassis 1. The two brushes 16 are respectively abutted against the two side walls of the track 00 to clean the dust on both sides of the track 00; the detection component is arranged on the rear side of the brush 16 to facilitate the detection of both sides of the track after cleaning, thereby ensuring the accuracy of the detection.

[0038] Further optimize the above technical solution, such as Figure 1 As shown, the outer side of the chassis 1 is provided with a track gauge detection element 15 for detecting the distance between the two tracks 00. The track gauge detection element 15 is an infrared distance measuring sensor, and the camera 2 includes two industrial cameras, which are arranged at intervals on the top of the chassis 1 along the length direction of the track 00.

[0039] In specific applications, the Beidou positioning module and communication module that are wirelessly connected to the railway dispatching center can be installed in the chassis, and the movement of the trolley can be remotely controlled through the railway dispatching center; at the same time, a display screen connected to the industrial camera, infrared sensor and detection components is installed on the outside of the chassis. The industrial camera collects video images of the rail head in real time, and the detection video can be displayed in real time on the display screen, and can also be sent to the railway dispatching center through the communication module. If damage to the track is detected, the location information of the damaged part is obtained through the Beidou positioning module, and the damaged location can also be manually marked at any time. If an obstacle is encountered during the operation of the trolley, it will be detected by the infrared sensor and the information will be sent to the controller. The controller will then send a stop signal to the motor, and the trolley will stop moving; at the same time, the communication module will send the obstacle information and location information to the railway dispatching center.

[0040] In summary, the utility model has the advantages of simple structure and convenient and fast operation. The trolley moves along the track under the drive of the motor, uses a scraper to pre-treat impurities on the track surface, and then uses a roller brush and a brush to perform secondary cleaning on the track surface to ensure detection accuracy; the image of the rail head is collected by the industrial camera in the chassis to detect whether there are defects on the track surface, and the ultrasonic generator and ultrasonic receiver on the inner wall of the chassis are used to detect whether there are defects on the side of the track.
