The traditional manual flaw detection method has been difficult to meet the detection requirements of large-scale railway networks.

Under harsh climate conditions such as high temperature, low temperature, heavy rain, and strong wind, it is difficult to carry out manual detection work normally, and the work efficiency and detection quality of the detection personnel will be seriously affected. (2) Low intelligence and integration: 90% of existing devices only support single functions (such as ultrasonic or visual detection), lack multi-modal data fusion, and the false judgment rate of faults is ≥20%.

[0008] Preferably, the visual detection assembly includes an industrial camera and a fill light. Both the industrial camera and the fill light are fixedly spaced above the traveling cross beam through guide rods.

[0009] Preferably, the liquid storage tank is arranged in an inclined shape, and a recovery pump is fixedly connected to the lower side of the liquid storage tank.

[0013] The present invention also proposes an integrated track defect detection method, which uses the integrated track defect detection device described in any one of the above. The specific steps are as follows: S1, Equipment assembly and preparation; Connect the traveling cross beam of the flaw detection trolley to the traveling longitudinal beam through a connection assembly. Install the visual detection assembly above the traveling cross beam, and install the ultrasonic detection assembly at the bottom of the traveling longitudinal beam, and make the ultrasonic detection assembly located between the liquid storage tank and the dialing and discharging assembly; fix the liquid storage tank filled with flaw detection liquid or coupling agent on the support fixture; Install one end of the traveling cross beam in the flaw detection trolley above one side rail, install the traveling longitudinal beam above the other side rail, and perform auxiliary positioning through the auxiliary positioning wheels to ensure its traveling position; S2, Track detection; Start the spraying assembly, and coat the flaw detection liquid or coupling agent in the liquid storage tank on the rail through the spraying assembly; perform visual detection on the surface of the rail through the visual detection assembly, and at the same time, perform ultrasonic detection on the inside of the rail through the ultrasonic assembly on the traveling longitudinal beam; S3, Liquid coating removal and recovery; Two groups of dialing and arranging components act alternately to wipe off the liquid above the rail; specifically, start the driving motor, the driving motor drives the swing arm to rotate, the swing arm drives the dial plate to move outwards, and the dial plate moves along the trajectory line until the liquid above the rail is pushed to the recovery boxes on both sides, and the liquid in the recovery boxes is then transported to the recovery tank connected above the traveling longitudinal beam through the recovery pump.

When focusing on detecting the internal cracks of the rail, the coupling agent is filled into the liquid storage tank, and the ultrasonic component is used to detect the inside of the rail, and then the coupling agent on the rail surface is wiped off and recovered by the dialing and arranging component.

Detailed implementation manners

[0025] To make the objectives, features, and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all of 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.

[0026] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0029] As Figures 1 to 6 shown, this embodiment provides an integrated track defect detection device, including a flaw detection trolley, which is composed of a traveling cross beam 1 and a traveling longitudinal beam 2 connected to the end of the traveling cross beam 1. A visual detection component 3 and an ultrasonic detection component 4 are respectively connected to the traveling cross beam 1 and the traveling longitudinal beam 2; a liquid storage tank 5 is detachably connected above the traveling longitudinal beam 2, and the flaw detection liquid or coupling agent inside the liquid storage tank 5 is coated above the steel rail 18 through a spraying component 6; It further includes two groups of dialing and discharging components 7, which are evenly arranged at the bottom of the traveling longitudinal beam 2 and are located behind the liquid storage tank 5 and the visual detection component 3, and alternately act to wipe off the flaw detection liquid or coupling agent liquid above the steel rail 18. The dialing and discharging component 7 includes a driving motor 71 arranged inside the traveling longitudinal beam 2, the output shaft of the driving motor 71 is connected with a swing arm 72, and a dial plate 73 is hinged to the bottom of the swing arm 72; it also includes an auxiliary rod 74 hinged to the bottom of the traveling longitudinal beam 2, and the other end of the auxiliary rod 74 is rotatably connected with the dial plate 73. When the driving motor drives the swing arm 72 to rotate, it drives the dial plate 73 to move accordingly. By forming a constraint on one end of the dial plate 73 through the auxiliary rod 74, the other end of the dial plate 73 can move along the track line 75, so as to realize a reciprocating motion and dial out the liquid on the upper surface of the steel rail 18; It further includes a recovery box 8, which is fixed on both sides of the traveling longitudinal beam 2 and is used to collect the liquid dialed out from the steel rail 18 by the dial plate 73.

[0030] At present, the flaw detection of the rail 18 mainly relies on two technologies: visual flaw detection and ultrasonic flaw detection. Visual flaw detection mainly uses a high-resolution camera and an image recognition algorithm to detect surface defects of the rail 18. In this process, a flaw detection liquid needs to be infiltrated into the surface crack defects of the rail 18 for imaging, and the visual detection component 3 is used to capture or mark the defects; ultrasonic flaw detection is used to detect internal defects of the rail 18. By emitting ultrasonic waves and analyzing the reflected waves, internal cracks, looseness and other problems can be located. In this process, a coupling agent can be used to improve the transmission of acoustic energy between the ultrasonic detection component 4 and the rail 18, and to increase the reciprocating transmission rate of the ultrasonic sound on the rail 18.

[0031] Due to the lack of relevant recycling equipment, the flaw detection liquid or the coupling agent is discarded beside the rail 18 after use, which will have a certain impact on the surrounding environment. For example, the imaging penetrant in the flaw detection liquid usually contains components such as organic solvents and dyes. Discarding it beside the rail 18 is likely to damage the ecological balance of the surrounding soil and pollute its environment; the coupling agent remains on the surface of the rail 18 after use, and its dryness may affect the contact performance between the rail 18 and the train wheels.

[0032] Based on the above problems, an integrated track defect detection device has been studied. The flaw detection liquid or the coupling agent on the surface of the rail 18 is deflected to one side of the rail 18 by the deflector component 7. Two sets of deflector components 7 form a cycle of "wiping - resetting - wiping", which has a better cleaning effect, especially suitable for long-term operation at high speed of the flaw detection trolley. The double deflector plates 73 can achieve non-stop alternating operation, which can greatly improve the cleaning effect on the surface of the rail 18; in addition, its movement trajectory is to move to both sides, which can deflect the liquid on the upper surface of the rail 18 into the recovery boxes 8 on both sides, realizing precise diversion, and recovering the flaw detection liquid or the coupling agent on the upper surface of the rail 18 to avoid its residue on the rail 18, affecting the surrounding environment or the contact performance with the train wheels.

[0033] In some embodiments, the traveling cross beam 1 includes a main beam body 101 and a connecting beam 102 located at the end of the main beam body 101. The main beam body 101 and the connecting beam 102 are detachably connected through a connecting component 103. This connecting piece adopts a conventional connection structure and will not be elaborated here. The connecting beam 102 is arranged perpendicular to the traveling longitudinal beam 2. After installation, the bottom of the flaw detection trolley as a whole presents a T-shaped structure. The detachable connection between the main beam body 101 and the connecting beam 102 through the connecting piece enables the flaw detection trolley to be disassembled into two parts, which is convenient for storage or transportation, can reduce the space occupation, and can be quickly installed during use.

[0034] In some embodiments, traveling wheels 9 are respectively connected to the body end of the main body beam 101 and both ends of the traveling longitudinal beam 2. The traveling wheels 9 are arranged in a triangular pattern and are respectively located above two groups of steel rails 18, and are used to drive the traveling cross beam 1 and the traveling longitudinal beam 2 above them to move; auxiliary positioning wheels 20 are respectively arranged inside the traveling wheels 9. The auxiliary positioning wheels 20 are arranged at the bottom of the traveling cross beam 1 or the traveling longitudinal beam 2 and can move left and right through components such as springs, which is convenient for installing and fitting them to the side of the steel rail 18 to avoid phenomena such as derailment when the flaw detection trolley is traveling. This structure is prior art and will not be elaborated here.

[0035] In some embodiments, the visual detection component 3 includes an industrial camera and a fill light. Both the industrial camera and the fill light are fixedly spaced apart above the traveling cross beam 1 through guide rods. The industrial camera is used to capture cracks on the upper surface of the steel rail 18, and the fill light provides suitable illumination for the industrial camera during night detection to ensure clear imaging. During night flaw detection operations, first evenly coat the flaw detection liquid on the upper surface of the steel rail 18, and then use the dialing and discharging component 7 to wipe off the flaw detection liquid on the surface of the steel rail 18. If there are cracks in the steel rail 18, the flaw detection liquid will seep into them, and the flaw detection liquid in the cracks is difficult to be completely removed by the dialing plate 73. At this time, in cooperation with the industrial camera above, the contour of the crack with the flaw detection liquid will be more prominent in the dark environment, and the industrial camera can accurately capture the crack image for subsequent analysis and processing.

[0036] In some embodiments, the recovery box 8 is arranged in an inclined shape. A recovery pump 10 is fixedly connected to the lower side of the recovery box 8. The recovery pump 10 transports the liquid in the recovery box 8 to the inside of the recovery tank 12 above the traveling longitudinal beam 2 through a recovery pipeline 11. The inclined design enables the liquid in the recovery box 8 to converge towards the lower side under the action of gravity, and in cooperation with the recovery pump 10, it can accurately and efficiently extract the liquid that has been dialed out, reduce residues, and transport it to the recovery tank 12 above the traveling longitudinal beam 2 through the recovery pipeline 11. After the detection process is completed, the waste liquid inside it is then processed. Further, a filter plate can be arranged in the recovery box 8 to filter the liquid to a certain extent to avoid affecting the service life of the recovery pump 10.

[0037] In one embodiment, a support fixture 13 is fixed above the traveling longitudinal beam 2, and the above-mentioned liquid storage tank 5 is placed on the support fixture 13. The liquid storage tank 5 is connected to the spraying component 6 through the support fixture 13 and the drainage channel 14 at the bottom of the traveling longitudinal beam 2. This detachable method facilitates the connection of the liquid storage tank 5 to the support fixture 13, enabling the flaw detection liquid or coupling agent inside the liquid storage tank 5 to be coated above the steel rail 18 through the spraying component 6; Further, the support member 13 has a rectangular structure, and a placement cavity for placing the liquid storage tank 5 is provided inside. Grooves 15 are provided on the four side walls of the support member 13. A limiting block 16 is hinged in the groove 15. The limiting block 16 has an L-shaped structure. A clamping block 17 is fixed to the top of the limiting block 16. A clamping groove 51 engaged with the clamping block 17 is provided on the outer wall of the liquid storage tank 5. After the liquid storage tank 5 is placed in the support member 13, the bottom of the limiting block 16 can be pressed. Through the restraint of the rotating shaft, the top of the limiting block 16 is pressed in the middle, so that the clamping block 17 is engaged with the clamping groove 51, and the liquid storage tank 5 is positioned above the support member 13.

[0038] In some embodiments, the spraying assembly 6 includes an output pump 61 disposed inside the traveling longitudinal beam 2. The liquid discharge channel 14 is connected to the input end of the output pump 61. It further includes a spraying box 62, and a plurality of groups of nozzles 63 are fixed to the bottom of the spraying box 62. The output end of the output pump 61 is communicated with the nozzles 63 through the spraying box 62. In the coating stage, the liquid storage tank 5 is communicated with the liquid discharge channel 14. The liquid in the liquid discharge channel 14 is conveyed to the inside of the spraying box 62 by the output pump 61, and the solution is coated on the upper surface of the rail 18 by the nozzles 63 inside the spraying box 62.

[0039] In some embodiments, a laser distance measuring assembly 19 is provided at one end of the traveling cross beam 1 away from the traveling longitudinal beam 2. The gauge of the two rails 18 is measured by the laser distance measuring assembly 19 to determine whether the gauge meets the standard.

[0040] It should be noted that a processor is provided on the traveling cross beam 1. The processor can transmit the flaw detection data to the observation device in real time through a wireless network so that the staff can grasp the detection situation at any time. In addition, a power supply is also equipped on the traveling cross beam 1 to supply power to each power unit of the flaw detection trolley to ensure the stable operation of the equipment.

[0041] In the present invention, an integrated track defect detection method is also proposed. Using the above-mentioned integrated track defect detection equipment, it includes the following steps: S1, equipment assembly and preparation; Connect the traveling cross beam 1 of the flaw detection trolley to the traveling longitudinal beam 2 through the connection assembly 103. Install the visual detection assembly 3 above the traveling cross beam 1, and install the ultrasonic detection assembly 4 at the bottom of the traveling longitudinal beam 2, and make the ultrasonic detection assembly 4 located between the liquid storage tank 5 and the discharging and arranging assembly 7; fix the liquid storage tank 5 filled with the flaw detection liquid or coupling agent on the support member 13; Install one end of the traveling cross beam 1 in the flaw detection trolley above one side rail 18, install the traveling longitudinal beam 2 above the other side rail 18, and perform auxiliary positioning through the auxiliary positioning wheels 20 to ensure its traveling position; S2, track detection; Start the spraying component 6, and apply the flaw detection liquid or coupling agent in the liquid storage tank 5 onto the upper part of the rail 18 through the spraying component 6; visually inspect the surface of the rail 18 through the visual inspection component 3, and at the same time, perform ultrasonic inspection on the inside of the rail 18 by the ultrasonic component on the traveling longitudinal beam 2; Further, in S2, selectively fill the flaw detection liquid or coupling agent into the liquid storage tank 5 according to the detection focus; During night detection, to further highlight and capture the cracks on the surface of the rail 18, fill the flaw detection liquid into the liquid storage tank 5, apply the flaw detection liquid onto the surface of the rail 18 through the spraying component 6, and then wipe and recycle the flaw detection liquid on the surface of the rail 18 through the wiping and discharging component 7. Since the flaw detection liquid in the cracks cannot be completely wiped off, the cracks can be highlighted by the flaw detection liquid, and the visual detection device is used to capture and mark them; When focusing on detecting the internal cracks of the rail 18, fill the coupling agent into the liquid storage tank 5, cooperate with the ultrasonic component to detect the inside of the rail 18, and then wipe and recycle the coupling agent on the surface of the rail 18 through the wiping and discharging component 7.

[0042] S3, liquid application, wiping and recycling; The two wiping and discharging components 7 act alternately to wipe off the liquid above the rail 18; specifically, start the driving motor 71, the driving motor 71 drives the swing arm 72 to rotate, the swing arm 72 drives the baffle 73 to move outwards, and the baffle 73 moves along the trajectory line 75 until the liquid above the rail 18 is pushed to the recovery boxes 8 on both sides. The liquid in the recovery boxes 8 is then transported to the recovery tank 12 connected above the traveling longitudinal beam 2 through the recovery pump 10.

[0043] Although the specific implementation manners of the invention are described above in conjunction with the drawings, it is not a limitation to the protection scope of the invention. Based on the technical solutions of the invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the invention.

Liquid smearing removal and recovery; The two sets of dialing and discharging components act alternately to smear the liquid above the rail (18); specifically, start the drive motor (71), the drive motor (71) drives the swing arm (72) to rotate, the swing arm (72) drives the dialing plate (73) to move outwards, the dialing plate (73) moves along the trajectory line (75) until the liquid above the rail (18) is pushed into the recovery boxes (8) on both sides, and the liquid in the recovery boxes (8) is then transported into the recovery tank (12) connected above the traveling longitudinal beam (2) through the recovery pump (10).

10. An integrated track defect detection method according to claim 9, characterized in that, In S2, selectively fill the flaw detection liquid or coupling agent into the liquid storage tank (5) according to the detection focus; During night detection, to further highlight and capture the cracks on the surface of the rail (18), fill the flaw detection liquid into the liquid storage tank (5), coat the flaw detection liquid on the surface of the rail (18) through the spraying component (6), and then smear and recover the flaw detection liquid on the surface of the rail (18) through the dialing and discharging component. Since the flaw detection liquid in the cracks cannot be completely smeared, the cracks can be highlighted by the flaw detection liquid, and the visual detection component (3) is used to capture and mark them; When focusing on detecting the internal cracks of the rail (18), fill the coupling agent into the liquid storage tank (5), cooperate with the ultrasonic component to detect the inside of the rail (18), and then smear and recover the coupling agent on the surface of the rail (18) through the dialing and discharging component.
