[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0038] The embodiment of the present application provides a vehicle-mounted system for railway flaw detection operations, which can solve the problems in the related art that the rail flaw detection vehicle and personnel are transported separately, and the equipment is completely loaded and unloaded manually without a special fixed point and is only limited by ropes.

[0039] See Figures 1 to 14As shown in the figure, an on-vehicle system for railway flaw detection operations provided by an embodiment of the present application includes: a loading vehicle 3, a flaw detection device 1, and a loading and unloading device 2. A passenger area 30 and a cargo compartment area 31 are provided on the loading vehicle 3; a mating structure 16 is provided on the flaw detection device 1; the loading and unloading device 2 is disposed inside the cargo compartment 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, and a locking structure 25 is provided on the loading and unloading structure. 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, the flaw detection device 1 is driven to move into or out of the cargo compartment area 31.

[0040] In the present application, a passenger area 30 and a cargo compartment area 31 are provided on the loading vehicle 3, which can transport the flaw detection device 1 and personnel at the same time; and a loading and unloading structure is provided inside the cargo compartment area 31. The flaw detection device 1 can be loaded and unloaded through the loading and unloading structure. A locking structure 25 is provided on the loading and unloading structure, which cooperates with the mating structure 16 provided on the flaw detection device 1. When the flaw detection device 1 is installed inside the cargo compartment area 31, the flaw detection device 1 is locked through the cooperation of the locking structure 25 and the mating structure 16.

[0041] On the basis of the above embodiment, in this embodiment, the flaw detection device 1 includes: a working platform 10, a flaw detector 11, and a coupling agent 14. A front axle body 12 and a rear axle body 13 are provided at the bottom end of the working platform 10, and the mating structure 16 is provided at the bottom end 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 device 1 is designed with a detachable structure, and any module can be lifted by only two people; that is to say, the flaw detector 11, the coupling agent 14, the front axle body 12, and the rear axle body 13 can all be detached from the working platform 10. A battery management system 15 is provided on the working platform 10 to enable the flaw detection device 1 to be driven by a battery, which is environmentally friendly and energy-saving, and the detection speed reaches 15 kilometers per hour. Wheel-type probes are used for detection. The ultrasonic wheel-type probes with 9 channels show the data of 18 channels in total for two rails in the form of a B-scan on an industrial-grade high-brightness liquid crystal display screen. The non-contact nature of the wheel-type probes ensures good coupling on curved sections and tracks with a high degree of rail surface wear, and can effectively detect nuclear damage in the rail head, crack in the bolt hole of the rail web, and transverse crack in the rail bottom, etc., and is equipped with an alarm to automatically pop up a window, which is convenient for the operator to perform real-time detection of the rail.

[0043] On the basis of the above embodiment, in this embodiment, the passenger area 30 on the loading vehicle 3 is set to a 3+2+4 seat layout according to regulatory requirements and personnel comfort; the connection between the passenger area 30 and the cargo compartment area 31 is a middle partition to separate people from the flaw detection device 1.

[0044] The frame assembly 20 is fixed inside the cargo compartment 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 compartment area 31, and the pulley track 201 is fixed on the frame body 200 so that the loading and unloading structure can move along the pulley track 201. A fixed plate 203 is fixedly connected between 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 beam of the whole vehicle, and the force received is transmitted to the longitudinal beam.

[0045] Further, in order to improve the stability of the movement of the loading and unloading structure, a fixed roller assembly 202 is provided on the frame assembly 20. The fixed roller assembly 202 is arranged below the sliding frame 21 and is in rolling connection with the sliding frame 21. Specifically, a fixed wheel column 205 is fixedly connected to the frame body 200, the fixed roller assembly 202 is installed at the top of the fixed wheel column 205, and the fixed roller assembly 202 is attached to 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 stable support for it.

[0046] Further, the pulley track 201 includes a straight section. One end of the straight section close to the inlet and outlet of the cargo compartment area 31 slopes upward and extends to form an inclined section. Refer to Figure 4 As shown, when the moving end of the loading and unloading structure moves toward the inlet and outlet of the cargo compartment area 31, it first passes through the straight section of the pulley track 201 and then enters the inclined section. One end of the moving end of the loading and unloading structure 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 downward due to its own weight to facilitate the operator to install the flaw detection device 1 on the moving end of the loading and unloading structure.

[0047] Based on the above embodiment, 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 a locking structure 25 is fixed on 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] Among them, the sliding frame 21 includes an upper frame 212. Columns 210 are arranged on the upper frame 212, and roller members 213 are arranged on the columns 210. The roller members 213 are in rolling connection with the inside of the pulley track 201. In order to improve the structural stability of the sliding frame 21 and facilitate the connection between the driving structure 22 and the sliding frame 21, a connecting beam 211 is fixedly connected to the upper frame 212, so that the fixed end of the driving structure 22 is fixed on the frame body 200, and the output end of the driving structure 22 is fixed to the connecting beam 211. Therefore, the sliding frame 21 can move easily, be connected to the pulley track 201, and make a reciprocating circular motion along the specific pulley track 201 on the frame assembly 20 under the action of its own rollers and the driving structure 22.

[0050] Among them, the driving structure 22 includes: an oil cylinder assembly 221 and an oil cylinder control module 222. The oil cylinder assembly 221 is connected to the frame body 200 in the frame assembly 20 through an oil cylinder fixed support 220, and the output end of the oil cylinder assembly 221 is fixed to the connecting beam 211; the oil cylinder control module 222 is installed on the frame assembly 20 and is connected to the oil cylinder assembly 221. In this embodiment, in order to maximize cost savings, the oil cylinder assembly 221 is set as a three-stage oil cylinder. The telescoping and moving speed of the three-stage oil cylinder are controlled by the oil cylinder control module 222. The oil cylinder control module 222 controls the telescoping and moving speed of the oil cylinder assembly 221 by controlling the working pressure, flow rate of the hydraulic power unit system, and the opening and closing of the solenoid valve.

[0051] Furthermore, a shock pad 204 is arranged inside the pulley track 201 on the side close to the inlet and outlet of the cargo compartment area 31. The purpose of setting the shock pad 204 is to add a barrier to the shaking caused by the too fast descending speed of the upper frame 212.

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

[0053] On the basis of the above embodiments, in this embodiment, the locking structure 25 includes: a mounting seat 250, two limiting seats 255, a locking tongue 252, a spring 251, a locking groove 254, and an adjusting rod 253. The mounting seat 250 is fixed on the loading and unloading structure; the two limiting seats 255 are fixedly arranged on the mounting seat 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 arranged between the two limiting seats 255; the locking groove 254 is fixed on the mounting seat 250 and is located on one side of the limiting seat 255; the adjusting rod 253 is rotatably connected to the locking tongue 252, and one end is slidably connected to the inside of the locking groove 254.

[0054] Specifically, refer toFigure 8 As shown, the mounting base 250 is fixed at the four corner positions of the upper frame 212, and one of the wall surfaces of the mounting base 250 is vertically arranged. 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 passing gap for the mating structure 16 to pass through is formed between the end of the locking tongue 252 and the vertically arranged wall surface of the mounting base 250. A receiving gap for the mating structure 16 to be received is formed between the bottom of the locking tongue 252 and the bottom wall of the mounting base 250. An adjusting rod 253 is rotatably connected to the locking tongue 252. It should be noted that the adjusting rod 253 will not rotate on the locking tongue 252 in the natural state and will only rotate on the locking tongue 252 when pressed. In addition, 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. Among them, a slot hole is opened in the middle of the locking groove 254. The slot hole includes a first slot 2540 and a second slot 2541. One end of the adjusting rod 253 passes through the slot hole. When the adjusting rod 253 is located in the first slot 2540, it is slidably connected to the first slot 2540. When the adjusting rod 253 is pressed, it rotates from the first slot 2540 into the second slot 2541.

[0056] On the basis of the above embodiment, in this embodiment, the mating structure 16 includes: a snap ring 160, a connecting rod 161, and an operating plate 162. The snap ring 160 is fixedly connected to the bottom end of the flaw detection device 1. The snap ring 160 is used to pass through the passing gap and be locked in the receiving gap; the connecting rod 161 is rotatably connected to the bottom end of the flaw detection device 1; the operating plate 162 is fixed on the connecting rod 161, and one end of the operating plate 162 is an adjusting rod fitting end.

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

[0058] See Figure 3 As shown, after the snap ring 160 passes through the passing gap and reaches the receiving gap, it cannot move up and down after being held by the locking tongue 252 and the mounting base 250. It should be noted that since a spring 251 is arranged on the locking tongue 252 and a slope is arranged at the top end of the locking tongue 252, when the snap ring 160 presses down the locking tongue 252, the locking tongue 252 moves, increasing the passing gap so that the snap ring 160 can pass through. After the snap ring 160 passes through, the passing gap rebounds due to the spring 251 driving the locking tongue 252 and returns to the initial size. At this time, the snap ring 160 cannot pass through the passing gap and move up, thereby fixing the working platform 10.

[0059] Among them, a first inclined surface 1620 and a second inclined surface 1621 are provided on the operation panel 162, and a positioning groove 1622 is also provided between the first inclined surface 1620 and the second inclined surface 1621.

[0060] See Figures 10 to 12 As shown, this figure shows the process of moving the adjusting rod 253 from the first groove 2540 to the second groove 2541 through the operation panel 162. After the working platform 10 is installed and fixed, since the final position of the working platform 10 needs to be adjusted, the adjusting rod 253 can be first moved into the second groove 2541 and locked through the operation panel 162. At this time, rotate the operating handle 163 so that the operating handle 163 drives the adjusting rod 253 to rotate in the first direction. At this time, during the rotation of the second inclined surface 1621, it pushes the adjusting rod 253 to move, and the spring 251 contracts to move from Figure 10 the first position shown to Figure 11 the second position shown, and then the operating handle 163 drives the adjusting rod 253 to continue rotating. The adjusting rod 253 moves along the first inclined surface 1620 from Figure 11 the second position shown to Figure 12 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 exerts a force on the adjusting rod 253 in an oblique direction to make the adjusting rod 253 move downward, so that the adjusting rod 253 rotates into the positioning groove 1622 of the operation panel 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. Therefore, the adjusting rod 253 also reaches the second groove 2541 and is temporarily locked. Therefore, at this time, the locking tongue 252 retracts, and the working platform 10 can be freely installed and adjusted in position.

[0061] See Figures 13 to 14 As shown, this figure shows the process of moving the adjusting rod 253 from the second groove 2541 to the first groove 2540 through the operation panel 162. When the locking tongue 252 needs to return to its original position, continue to rotate the operating handle 163 in the first direction. At this time, the operation panel 162 can drive the adjusting rod 253 to rise from the second groove 2541 until the adjusting rod 253 is horizontally arranged, that is, from Figure 13 the third position shown to Figure 14 the fourth position shown, and rotate the operating handle 163 in the second direction. Since there is no longer a force in the oblique direction to make the adjusting rod 253 move downward at this time, 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, a front and rear axle mounting assembly 23 is further provided on the frame assembly 20. The front and rear axle mounting assembly 23 includes a linear guide rail 231. One end of the linear guide rail 231 close to the inlet and outlet of the cargo compartment area 31 is fixedly connected with a front and rear axle fixed slider 232, and one end of the linear guide rail 231 far from the inlet and outlet of the cargo compartment area 31 is fixedly connected with a front and rear axle driving slider 230. Therefore, the front axle body 12 and the rear axle body 13 of the flaw detection device 1 can be driven by the front and rear axle driving slider 230 and move to be fixedly limited between the front and rear axle fixed slider 232 and the front and rear axle driving slider 230.

[0063] A fixed box 255 is further provided on the frame assembly 20 for accommodating the flaw detector 11.

[0064] The specific process of the flaw detection device 1 moving out of the cargo compartment area 31 is as follows: When the loading vehicle 3 is ignited and in the N gear, the rear tailgate is opened, and the oil cylinder control module 222 is started. The upper frame 212 is moved along the pulley track 201 to the outside of the loading vehicle 3 through the oil cylinder assembly 221. When it is in Figure 1 position B in, the upper frame 212 completes the flipping action through the slow action of the inclined section of the pulley track 201 and the oil cylinder assembly 221; when the upper frame 212 is in Figure 1 position A in, the roller member 213 is limited by the shock pad 204 to reach a predetermined angle (the working platform 10 and the driving structure 22 < 15°), and at this time, the extension arm of the flaw detection device 1 is more than 20 CM away from the ground; the platform of the flaw detection device 1 completes the removal operation.

[0065] When the flaw detection device 1 moves into the cargo compartment area 31, first place the working platform 10 on the locking structure 25 of the upper frame 212 of the loading and unloading device 2 (locking principle: when the working platform 10 is placed on the locking structure 25, its own gravity pushes the bevel locking tongue 252 on the locking structure 25 inward. When the snap ring 160 completely drops, the locking tongue 252 is automatically locked under the action of the spring 251), and place the coupling agent 14 on the working platform 10 and tie it firmly with a binding strap. Control the oil cylinder control module 222 to make the working platform 10 retract backward. When moving from position A to Figure 1 position C shown, the assembly of the working platform 10 is completed; the front axle body 12 and the rear axle body 13 of the flaw detection device 1 are driven by the front and rear axle driving slider 230 and move to be fixedly limited between the front and rear axle fixed slider 232 and the front and rear axle driving slider 230, and place the flaw detector 11 in the fixed box 255 to complete the assembly of the flaw detection device 1.
