[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0038] This application provides a vehicle-mounted system for railway flaw detection operations, which can solve the problems in related technologies where railway flaw detection vehicles and personnel are transported separately, equipment is entirely dependent on manual loading and unloading, and there are no dedicated fixed points for limiting movement only by ropes.

[0039] See Figures 1 to 14As shown in the figure, this application provides a vehicle-mounted system for railway flaw detection operations, which includes: a loading vehicle 3, a flaw detection device 1, and a loading and unloading device 2. The loading vehicle 3 is provided with a passenger area 30 and a cargo area 31. The flaw detection device 1 is provided with a mating structure 16. The loading and unloading device 2 is located inside the cargo area 31. The loading and unloading device 2 includes a frame assembly 20 and a loading and unloading structure. One end of the loading and unloading structure is movably connected to the frame assembly 20. The loading and unloading structure is provided with a locking structure 25. The loading and unloading structure is locked to the mating structure 16 on the flaw detection device 1 through the locking structure 25. When the loading and unloading structure moves along the frame assembly 20, it drives the flaw detection device 1 to move into the cargo area 31 or removes the flaw detection device 1 from the cargo area 31.

[0040] In this application, a passenger area 30 and a cargo area 31 are provided on the loading vehicle 3, which can transport the flaw detection equipment 1 and personnel at the same time; and a loading and unloading structure is provided inside the cargo area 31, through which the flaw detection equipment 1 can be loaded and unloaded. A locking structure 25 is provided on the loading and unloading structure, which works in conjunction with the cooperating structure 16 provided on the flaw detection equipment 1. When the flaw detection equipment 1 is installed inside the cargo area 31, the flaw detection equipment 1 is locked by the locking structure 25 and the cooperating structure 16.

[0041] Based on the above embodiments, in this embodiment, the flaw detection device 1 includes: a working platform 10, a flaw detector 11, and a coupling agent 14. The bottom of the working platform 10 is provided with a front axle body 12 and a rear axle body 13, and a mating structure 16 is provided at the bottom of the working platform 10. The flaw detector 11 is connected to the working platform 10. The coupling agent 14 is provided on the working platform 10.

[0042] Specifically, the flaw detection equipment 1 features a detachable structure design, requiring only two people to lift any module; that is, the flaw detector 11, coupling agent 14, front axle body 12, and rear axle body 13 can all be disassembled from the work platform 10. The work platform 10 is equipped with a battery management system 15, enabling the flaw detection equipment 1 to be battery-powered, environmentally friendly and energy-saving, with a detection speed of up to 15 kilometers per hour. It employs wheel-type probes, with 9 channels of ultrasonic wheel probes. Data from 18 channels across both rails is displayed in B-scan format on an industrial-grade high-brightness LCD screen. The non-contact nature of the wheel probes ensures good coupling in curved sections and on rails with high wear, effectively detecting rail head defects, rail web bolt hole cracks, and transverse cracks at the rail base. An automatic alarm pop-up window facilitates real-time rail inspection by the operator.

[0043] Based on the above embodiments, in this embodiment, the passenger area 30 on the loading vehicle 3 is configured with 3+2+4 seats according to regulatory requirements and personnel comfort; the connection between the passenger area 30 and the cargo area 31 is a central partition to separate people from the flaw detection equipment 1.

[0044] The frame assembly 20 is fixed inside the cargo area 31. The frame assembly 20 includes a frame body 200 and a pulley track 201. The frame body 200 is fixed inside the cargo area 31, and the pulley track 201 is fixed on the frame body 200 to allow the loading and unloading structure to move along the pulley track 201. A fixing plate 203 is fixedly connected between the two longitudinal bars of the frame body 200 to improve the structural strength of the frame body 200. In this embodiment, the frame body 200 is fixed to the longitudinal beams of the vehicle, and the force it receives is transmitted to the longitudinal beams.

[0045] Furthermore, to improve the stability of the loading and unloading structure's movement, a fixed roller assembly 202 is provided on the frame assembly 20. The fixed roller assembly 202 is located below the sliding frame 21 and is tactilely connected to the sliding frame 21. Specifically, a fixed wheel post 205 is fixedly connected to the frame body 200. The fixed roller assembly 202 is installed on the top of the fixed wheel post 205 and is made to fit against the moving end of the loading and unloading structure. When the moving end of the loading and unloading structure moves, the fixed roller assembly 202 provides it with stable support.

[0046] Furthermore, the pulley track 201 includes a straight section, which slopes upward and extends towards the end near the entrance / exit of the warehouse area 31 to form an inclined section. See also Figure 4 As shown, when the moving end of the loading and unloading structure moves toward the entrance and exit side of the warehouse area 31, it first passes through the straight section of the pulley track 201 and then enters the inclined section. In the moving end of the loading and unloading structure, one end is slidably connected to the pulley track 201, and the other end is supported by the fixed roller assembly 202. When the end slidably connected to the pulley track 201 moves to the inclined section, the other end will tilt downwards due to its own weight, so as to facilitate the manual installation of the flaw detection equipment 1 on the moving end of the loading and unloading structure.

[0047] Based on the above embodiments, in this embodiment, the loading and unloading structure includes: a sliding frame 21 and a driving structure 22. The sliding frame 21 is slidably connected to the frame assembly 20, and the locking structure 25 is fixed to the sliding frame 21. The fixed end of the driving structure 22 is fixed to the frame assembly 20, and the output end of the driving structure 22 is fixed to the sliding frame 21.

[0048] Specifically, the sliding frame 21 is the moving end of the loading and unloading structure.

[0049] The sliding frame 21 includes an upper frame 212, on which a column 210 is mounted. Roller components 213 are mounted on the column 210 and are rotatably connected to the pulley track 201. To improve the stability of the sliding frame 21 and facilitate the connection between the drive structure 22 and the sliding frame 21, a connecting beam 211 is fixedly connected to the upper frame 212. This allows the fixed end of the drive structure 22 to be fixed to the frame body 200, and the output end of the drive structure 22 to be fixed to the connecting beam 211. Therefore, the sliding frame 21 can move easily, connect to the pulley track 201, and, under the action of its own rollers and the drive structure 22, reciprocate along the specific pulley track 201 on the frame assembly 20.

[0050] The drive structure 22 includes a cylinder assembly 221 and a cylinder control module 222. The cylinder assembly 221 is connected to the frame body 200 in the frame assembly 20 via a cylinder fixing support 220, and the output end of the cylinder assembly 221 is fixed to the connecting beam 211. The cylinder control module 222 is mounted on the frame assembly 20 and connected to the cylinder assembly 221. In this embodiment, to maximize cost savings, the cylinder assembly 221 is set as a three-stage cylinder. The extension, retraction, and movement speed of the three-stage cylinder are controlled by the cylinder control module 222. The cylinder control module 222 controls the extension, retraction, and movement speed of the cylinder assembly 221 by controlling the working pressure, flow rate, and opening and closing of the solenoid valves of the hydraulic power unit system.

[0051] Furthermore, the pulley track 201 is equipped with a shock-absorbing pad 204 on the side near the entrance / exit of the warehouse area 31. The purpose of the shock-absorbing pad 204 is to provide a barrier against the shaking caused by the upper frame 212 falling too fast.

[0052] Furthermore, a clamping lock 24 is provided on the frame body 200, and a locking ring is fixed on the upper frame 212. The upper frame 212 can be fixed by the clamping lock 24 and the locking ring. When the upper frame 212 needs to be moved, the clamping lock 24 and the locking ring are released.

[0053] Based on the above embodiments, in this embodiment, the locking structure 25 includes: a mounting base 250, two limiting seats 255, a locking tongue 252, a spring 251, a locking groove 254, and an adjusting rod 253. The mounting base 250 is fixed to the mounting structure; the two limiting seats 255 are fixed to the mounting base 250 at intervals; the locking tongue 252 is slidably connected between the two limiting seats 255; the spring 251 is sleeved on the outer peripheral surface of the locking tongue 252 and is located between the two limiting seats 255; the locking groove 254 is fixed to the mounting base 250 and is located on one side of the limiting seats 255; the adjusting rod 253 is rotatably connected to the locking tongue 252, and one end is slidably connected inside the locking groove 254.

[0054] For details, see Figure 8 As shown, the mounting base 250 is fixed at the four corners of the upper frame 212, with one wall of the mounting base 250 being vertically oriented. Two limiting seats 255 are fixedly connected to the mounting base 250. A locking tongue 252 is slidably connected between the two limiting seats 255. One end of the locking tongue 252 passes through one of the limiting seats 255, and a through-gap is formed between the end of the locking tongue 252 and the vertically oriented wall of the mounting base 250 for the mating structure 16 to pass through. A receiving gap is formed between the bottom of the locking tongue 252 and the bottom wall of the mounting base 250 for the mating structure 16 to be accommodated. An adjusting rod 253 is rotatably connected to the locking tongue 252. It should be noted that the adjusting rod 253 does not rotate on the locking tongue 252 in its natural state; it only rotates on the locking tongue 252 when pressure is applied. Furthermore, a spring 251 is sleeved on the locking tongue 252. One end of the spring 251 is connected to one of the limiting seats 255, and the other end is connected to the adjusting rod 253.

[0055] A locking groove 254 is fixedly connected to the mounting base 250. The locking groove 254 has a slot in the middle, which includes a first groove 2540 and a second groove 2541. One end of the adjusting rod 253 passes through the slot. When the adjusting rod 253 is located in the first groove 2540, it is slidably connected to the first groove 2540. When the adjusting rod 253 is pressed, it rotates from the first groove 2540 into the second groove 2541.

[0056] Based on the above embodiments, in this embodiment, the cooperating structure 16 includes: a retaining ring 160, a connecting rod 161, and an operating plate 162. The retaining ring 160 is fixedly connected to the bottom end of the flaw detection equipment 1 and is used to pass through the penetration gap and lock within the receiving gap. The connecting rod 161 is rotatably connected to the bottom end of the flaw detection equipment 1. The operating plate 162 is fixed on the connecting rod 161, and one end of the operating plate 162 is the adjusting rod contact end.

[0057] The retaining ring 160, connecting rod 161 and operating plate 162 are all located at the bottom of the working platform 10.

[0058] See Figure 3 As shown, after the retaining ring 160 passes through the through-gap, it reaches the receiving gap and is held in place by the locking tongue 252 and the mounting base 250, preventing it from moving up or down. It should be noted that because a spring 251 is provided on the locking tongue 252, and a slope is provided at the top of the locking tongue 252, when the retaining ring 160 presses down on the locking tongue 252, the locking tongue 252 moves, increasing the through-gap to allow the retaining ring 160 to pass through. After the retaining ring 160 passes through, the through-gap is restored to its initial size due to the spring 251 causing the locking tongue 252 to spring back. At this point, the retaining ring 160 cannot pass through the through-gap to move upwards, thus fixing the working platform 10.

[0059] The operation panel 162 is provided with a first inclined surface 1620 and a second inclined surface 1621, and a positioning groove 1622 is provided between the first inclined surface 1620 and the second inclined surface 1621.

[0060] See Figures 10 to 12 As shown in the figure, this illustrates the process of moving the adjusting rod 253 from the first slot 2540 to the second slot 2541 via the operating plate 162. After the work platform 10 is installed and fixed, since it is necessary to adjust the final position of the work platform 10, the adjusting rod 253 can be moved into the second slot 2541 and locked using the operating plate 162. At this time, rotating the operating handle 163 causes the operating handle 163 to drive the adjusting rod 253 to rotate in the first direction. During this rotation, the second inclined surface 1621 pushes the adjusting rod 253 to move, and the spring 251 contracts to release the spring from the first slot 2540. Figure 10 The first position shown is moved to Figure 11 The second position is shown. Then, the operating handle 163 drives the adjusting rod 253 to continue rotating. The adjusting rod 253 moves along the first inclined plane 1620 from... Figure 11 The second position shown is moved to Figure 12 In the third position shown, when the operating handle 163 drives the adjusting rod 253 to continue rotating in the first direction, the first inclined surface 1620 applies an inclined force to the adjusting rod 253, causing it to rotate into the positioning groove 1622 of the operating plate 162. At this time, the positioning groove 1622 of the adjusting rod 253 is located on one side of the second groove 2541 of the locking groove 254, so the adjusting rod 253 also reaches the second groove 2541 and is temporarily locked. Therefore, the locking tongue 252 is retracted at this time, and the working platform 10 can be freely installed and adjusted in position.

[0061] See Figures 13 to 14 As shown in the figure, this illustrates the process of moving the adjusting rod 253 from the second slot 2541 to the first slot 2540 via the operating plate 162. When it is necessary for the locking tongue 252 to return to its original position, the operating handle 163 is rotated in the first direction. At this time, the operating plate 162 can drive the adjusting rod 253 to rise from the second slot 2541 to a horizontal position, that is, from... Figure 13 The third position shown is moved to Figure 14 The fourth position is shown, and the operating handle 163 is rotated in the second direction. Since there is no force in the oblique direction to make the adjusting rod 253 move downward, and under the action of the spring 251, the adjusting rod 253 and the locking tongue 252 are pushed back to the initial position to fix the retaining ring 160.

[0062] Based on the above embodiments, in this embodiment, the frame assembly 20 is further provided with a front and rear axle mounting assembly 23. The front and rear axle mounting assembly 23 includes a linear guide rail 231. A front and rear axle fixing slider 232 is fixedly connected to the end of the linear guide rail 231 near the inlet / outlet of the warehouse area 31, and a front and rear axle drive slider 230 is fixedly connected to the end of the linear guide rail 231 away from the inlet / outlet of the warehouse area 31. Therefore, the front axle body 12 and the rear axle body 13 of the flaw detection equipment 1 can be moved under the drive of the front and rear axle drive slider 230 and fixedly limited between the front and rear axle fixing slider 232 and the front and rear axle drive slider 230.

[0063] The frame assembly 20 is also equipped with a mounting box 255 for housing the flaw detector 11.

[0064] The specific process of removing the flaw detection equipment 1 from the cargo area 31 is as follows: When the loader 3 is in neutral (N) gear, the rear tailgate is opened, the hydraulic cylinder control module 222 is activated, and the upper frame 212 is moved along the pulley track 201 to outside the loader 3 via the hydraulic cylinder assembly 221. Figure 1 When in position B, the upper frame 212 is slowly rotated by the inclined section of the pulley rail 201 and the hydraulic cylinder assembly 221; when the upper frame 212 is in position B... Figure 1 When the roller component 213 is in position A, it is limited by the shock-absorbing pad 204 to a predetermined angle (the working platform 10 and the drive structure 22 are < 15°). At this time, the extension arm of the flaw detection device 1 is more than 20 cm above the ground; the platform of the flaw detection device 1 completes the removal operation.

[0065] When the flaw detection equipment 1 is moved into the warehouse area 31, the work platform 10 is first lifted and placed on the locking structure 25 of the upper frame 212 of the loading and unloading equipment 2 (locking principle: when the work platform 10 is placed on the locking structure 25, it uses its own weight to push the inclined locking tongue 252 on the locking structure 25 inward. When the retaining ring 160 falls completely, the locking tongue 252 automatically locks under the action of the spring 251). The coupling agent 14 is placed on the work platform 10 and secured with straps. The hydraulic cylinder control module 222 is used to retract the work platform 10. When it moves from position A to... Figure 1 When the position C shown is reached, the assembly of the work platform 10 is completed; the front axle body 12 and the rear axle body 13 of the flaw detection device 1 are moved to the position between the front and rear axle fixed slider 232 and the front and rear axle transmission slider 230 under the drive of the front and rear axle transmission slider 230 and are fixed and limited, and the flaw detector 11 is placed in the fixed box 255 to complete the assembly of the flaw detection device 1.
