Description

Technical Field

[0001] The invention relates to the technical field of railway transportation, in particular to a rail flaw detection and foreign matter handling rail vehicle. Background Art

[0002] With the network operation, the requirements for operation and maintenance of self-owned lines are getting higher and higher. The existing self-owned line management personnel and management mode are difficult to meet the needs. The entire self-owned line industry is eager to innovate management methods and realize intelligent operation and maintenance; double-track track automatic flaw detection electric detection equipment is an important part of the intelligent operation and maintenance of self-owned lines. "Track automatic flaw detection electric detection equipment" can realize sensitive detection and perception of damage to in-service rails, and has functions such as ultrasonic flaw detection, electromagnetic surface detection, and track geometric parameter detection;

[0003] Among them, electromagnetic detection technology is used to detect and evaluate the rolling fatigue damage (fish scale damage) on the upper surface of the rail caused by long-term rolling of the rail wheels, rail material deterioration and surface residual stress. It can effectively detect shallow surface defects of the rail, solve the blind spot problem of ultrasonic detection, and solve the shortcomings of high-definition imaging of the rail surface that is difficult to detect the defect depth information required for grinding.

[0004] During the operation of existing flaw detection and foreign body handling rail vehicles, the uneven road surface between the tracks often causes the electromagnetic sensors to shake violently, resulting in inaccurate detection data.

[0015] The present invention provides a rail flaw detection and foreign body handling rail vehicle. Compared with the prior art, it has the following beneficial effects:

[0016] (1) The rail flaw detection and foreign body handling rail vehicle reduces the influence of the ground on the electromagnetic sensor detection by extending and retracting the buffer spring and the fixed telescopic rod, which effectively buffers it. Combined with the balancing effect of the balance spring and the connecting shaft, when the auxiliary wheel passes through an uneven road surface, the electromagnetic sensor can also ensure the normal detection process of the rail to the greatest extent, thereby increasing the detection efficiency, reducing the influence of related factors, and ensuring the accuracy of the detection data.

Example

[0025] See also Figure 1-5 A rail flaw detection and foreign body handling rail vehicle comprises a rail 1 and a vehicle body 3 arranged above the rail 1. Four moving wheels 2 are rotatably arranged at the lower end of the vehicle body 3. A wheel axle 5 is fixedly arranged between two adjacent moving wheels 2. A back plate 4 is fixedly arranged on the side wall of one end of the vehicle body 3. A fixed telescopic rod 7 is fixedly arranged at the lower wall of the vehicle body 3. A transverse plate 6 is fixedly arranged at the lower end of the fixed telescopic rod 7. A buffer spring 8 is wound around the outer wall of the fixed telescopic rod 7. The buffer spring 8 is fixedly arranged between the vehicle body 3 and the transverse plate 6. An electromagnetic spring 8 is connected to the lower wall of the transverse plate 6 through a balancing component. Sensor 9, a crescent support frame 12 is fixedly provided at the lower end side wall of the electromagnetic sensor 9, the crescent support frame 12 and the electromagnetic sensor 9 are integrally formed, the lower end of the auxiliary wheel 13 and the lower end of the rail 1 are arranged on the same horizontal plane to prevent the crescent support frame 12 and the electromagnetic sensor 9 from falling off, and at the same time ensure that the auxiliary wheel 13 is in contact with the ground when the vehicle body 3 moves, two rotating shafts 14 are rotatably provided at the lower end side wall of the crescent support frame 12, and the auxiliary wheels 13 are fixed on the two rotating shafts 14, and the lower wall of the vehicle body 3 is fixed with A rotating rod 16 is fixedly provided between the side walls of the lower ends of the two fixing plates 15 for transverse rotation. A rotating cutting wheel 17 is fixedly provided on the side wall of the rotating rod 16. The side wall of the rotating cutting wheel 17 is flat, and the rotating cutting wheel 17 is provided at one end away from the back plate 4, so that the rotating cutting wheel 17 can process, clean and level the debris on the ground as the vehicle body 3 moves, which is convenient for the subsequent movement of the auxiliary wheel 13. A transmission belt 18 is provided between both ends of the rotating rod 16 and the wheel shaft 5, and a corresponding cleaning belt 18 is provided between the lower wall of the vehicle body 3 and the rotating cutting wheel 17. When the vehicle body 3 is moving and the ground that the auxiliary wheel 13 passes through is uneven, the impact of the ground on the detection of the electromagnetic sensor 9 can be reduced by the expansion and contraction of the buffer spring 8 and the expansion and contraction of the fixed telescopic rod 7, thereby effectively buffering it. In combination with the balancing effect of the balance spring 11 and the connecting shaft 10, when the auxiliary wheel 13 passes through an uneven road surface, the electromagnetic sensor 9 can also ensure the normal detection process of the rail 1 to the greatest extent, thereby increasing the detection efficiency, reducing the impact of related factors, and ensuring the accuracy of the detection data. Example

[0026] See also Figure 1-5This embodiment provides a technical solution based on the first embodiment: the balancing assembly includes a connecting shaft 10 rotatably arranged at the lower wall of the horizontal plate 6, the electromagnetic sensor 9 is rotatably connected to the horizontal plate 6 through the connecting shaft 10, and the lower wall of the horizontal plate 6 and the upper wall of the electromagnetic sensor 9 are also connected to each other through four balancing springs 11;

[0027] The cleaning assembly includes a plurality of fixed rods 19 which are laterally slidably arranged on the lower wall of the vehicle body 3. The plurality of fixed rods 19 and the rotating cutting wheel 17 are arranged correspondingly. A cleaning rod 20 is connected to the lower end of the fixed rod 19. The fixed rod 19 and the cleaning rod 20 are rotatably connected via a bearing 21. A limiting rod 22 is fixedly arranged at the side wall of the fixed rod 19. A resisting rod 23 is fixedly arranged at the side wall of the cleaning rod 20. The limiting rod 22 and the resisting rod 23 are arranged correspondingly. The limiting rod 22 and the resisting rod 23 are both arranged in an inclined shape, and an acute angle is formed between the limiting rod 22 and the resisting rod 23, so that when the cleaning rod 20 rotates, the limiting rod 22 can rotate and resist the resisting rod 23. As the vehicle body 3 moves, the wheel shaft 5 drives the rotating rod 16 to rotate through the transmission belt 18, thereby driving the rotating cutting wheel 17 to rotate, and the rotating cutting wheel 1 When the cutting wheel 17 rotates, it can cut and level the larger mud blocks on the ground, further ensuring the levelness of the road surface when the auxiliary wheel 13 passes through, and protecting the detection process of the electromagnetic sensor 9. When the rotating cutting wheel 17 is leveling the road surface, when mud blocks or stones are stuck between the rotating cutting wheels 17, they can be cleaned and scraped at the cleaning rod 20 when passing through the cleaning rod 20. When there are stones and other debris stuck tightly, the debris pushes the cleaning rod 20 to rotate, and the supporting rod 23 and the limiting rod 22 on the side wall of the cleaning rod 20 resist, so as to remove the debris. This process produces a certain buffering effect when cleaning the stuck debris, preventing the cleaning rod 20 from directly colliding with the debris, which may cause the cleaning rod 20 to break in the long run, effectively ensuring the working life of the cleaning component.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] During operation, first, when the vehicle body 3 is moving and the ground on which the auxiliary wheel 13 passes is uneven, the impact of the ground on the detection of the electromagnetic sensor 9 can be reduced by the expansion and contraction of the buffer spring 8 and the expansion and contraction of the fixed telescopic rod 7, thereby effectively providing a buffering effect thereon. In combination with the balancing effect of the balancing spring 11 and the connecting shaft 10, when the auxiliary wheel 13 passes over an uneven road surface, the electromagnetic sensor 9 can also ensure the normal detection process of the rail 1 to the greatest extent, thereby increasing the detection efficiency, reducing the impact of related factors, and ensuring the accuracy of the detection data.

[0030] As the vehicle body 3 moves, the wheel shaft 5 drives the rotating rod 16 to rotate through the transmission belt 18, thereby driving the rotating cutting wheel 17 to rotate. When the rotating cutting wheel 17 rotates, it can cut and level the larger mud blocks on the ground, further ensuring the flatness of the road surface that the auxiliary wheel 13 passes through, and protecting the detection process of the electromagnetic sensor 9;

[0031] When the rotating cutting wheel 17 is leveling the road surface, when mud or stones are stuck between the rotating cutting wheels 17, they can be cleaned and scraped off at the cleaning rod 20 when passing through the cleaning rod 20. When stones and other debris are stuck tightly, the debris pushes the cleaning rod 20 to rotate, and the supporting rod 23 and the limiting rod 22 on the side wall of the cleaning rod 20 resist, thereby removing the debris. This process produces a certain buffering effect when cleaning the stuck debris, preventing the cleaning rod 20 from directly colliding with the debris, which may cause the cleaning rod 20 to break in the long run, effectively ensuring the working life of the cleaning component.
