Description

Technical Field

[0001] This invention relates to a rail flaw detection device, and more particularly to a double-rail hand-pushed wheel type flaw detector. Background Technology

[0002] Currently, ultrasonic testing is the primary method used for rail flaw detection in my country. Several modes exist for ultrasonic rail flaw detection in my country. One mode uses a hand-push type ultrasonic rail flaw detector with a detection speed of 2 km / h. Its advantages include small size, convenient access to and from tracks, and strong detection capability, but its disadvantage is low detection efficiency, as it can only test one rail at a time. Another mode uses imported large-scale ultrasonic rail flaw detection vehicles combined with handcarts for fixed-point verification. This mode has high flaw detection efficiency but is large, costly, and requires high maintenance. A third mode uses the RT18-D dual-rail flaw detector with a detection speed of 15 km / h, but it is heavy, bulky, and has a complex operation process. Therefore, there is an urgent need for a small, simple, and lightweight detection device.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to solve the problem of low detection efficiency of current hand-push monorail flaw detectors.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0006] A dual-rail, hand-push-wheel flaw detector includes a main frame, a wheel assembly, a data processing assembly, and a coupling water tank. Two sets of wheel assemblies are detachably connected to both ends of the main frame. Each wheel assembly includes a wheel frame mechanism, a water turbine mechanism, and a centering mechanism. The wheel frame mechanism is connected to both ends of the main frame, the centering mechanism is connected to the wheel frame mechanism, the water turbine mechanism is connected to the centering mechanism, and the coupling water tank is connected to the wheel frame mechanism. A push rod is connected to the main frame, and the data processing assembly is connected to the main frame and the wheel assembly.

[0007] When in use, this invention allows for quick assembly and disassembly by detachably connecting the probe wheel assemblies to both sides of the main frame; it uses a water wheel for detection and a data processing assembly for data acquisition; the overall equipment has low friction, making it easy to move; it can simultaneously detect two rails, improving detection efficiency; compared to large rail ultrasonic testing, it eliminates the electric drive mechanism, making the overall equipment lighter; the centering mechanism can maintain the self-adaptation between the water wheel mechanism and the rail, ensuring detection accuracy.

[0008] Preferably, the probe frame mechanism includes a first frame, a second frame, and traveling wheels; the first frame has a convex structure with one end open, the second frame is connected to the first frame, the coupling water tank is connected to the second frame, the traveling wheels are connected to the bottom of both ends of the first frame, and the traveling wheels are connected to the data processing assembly.

[0009] Preferably, the first frame is connected to multiple quick-release pipe clamps, and both ends of the main frame are connected to the probe frame mechanism through quick-release pipe clamps.

[0010] Preferably, the probe frame mechanism further includes a third frame, a brush, and a nozzle. The third frame is connected to the side of one end of the first frame, the brush is connected to the third frame, the nozzle is connected to the third frame, and the nozzle is connected to the coupling water tank.

[0011] The brush is used to remove dust from the rails, and the nozzle is used to spray coupling fluid to expel air from the microscopic space of the rail surface. The water turbine body is filled with liquid and ultrasonic transducers. After the ultrasonic waves are emitted by the ultrasonic transducer, they pass through the internal medium of the water turbine and the water medium that is wetted on the surface of the rails before entering the rails to detect damage in the rails.

[0012] Preferably, the water turbine mechanism includes a water turbine body, a water turbine sleeve, and a water turbine frame. Two water turbine frames are connected to the centering mechanism. The two ends of the water turbine sleeve are adjustablely connected to the water turbine frame, and the two ends of the water turbine body are adjustablely connected to the water turbine sleeve.

[0013] Preferably, the water turbine mechanism further includes an angle adjustment mechanism, and the water turbine frame on one or / and both sides is connected to the water turbine sleeve through the angle adjustment mechanism.

[0014] Preferably, the water turbine mechanism further includes an inclination adjustment mechanism, which is connected to the outside of one side of the water turbine sleeve. One end of the rotating shaft of the water turbine body is connected to the water turbine sleeve, and the other end is connected to the water turbine sleeve and the inclination adjustment mechanism.

[0015] Preferably, the water turbine mechanism further includes a centering adjustment mechanism, which is connected to the outside of one side of the water turbine sleeve and is connected to the rotation shaft of the water turbine body.

[0016] The angle of the turbine body is adjusted by the angle adjustment mechanism, the tilt adjustment mechanism, and the centering adjustment mechanism, so that the turbine body is always effectively coupled with the rail.

[0017] Preferably, the centering mechanism includes a centering fixing plate, at least two sets of elastic sliding components, and two small rollers. The at least two sets of elastic sliding components are connected to the probe frame mechanism, the centering fixing plate is connected to the elastic sliding components, and the small rollers are connected to the bottom of the centering fixing plate.

[0018] Preferably, the elastic sliding assembly includes a mounting base, a sliding rod, a spring, and a slider. The mounting base is connected to the bottom of the centering fixing plate. Both ends of the sliding rod are connected to the mounting base. The slider is slidably connected to the sliding rod. The spring is sleeved on the sliding rod and its two ends abut against the mounting base and the slider, which are respectively located away from the water turbine mechanism.

[0019] The springs can adaptively keep the turbine mechanism centered, ensuring that the turbine and the rail are always coupled.

[0020] The advantages of this invention are:

[0021] (1) When using this invention, the probe wheel assembly can be detachably connected to both sides of the main frame, enabling quick assembly and disassembly; the water wheel is used for detection, and the data processing assembly realizes data acquisition. The overall equipment has low friction, is easy to push, and can detect two rails at the same time, improving detection efficiency; compared with large rail ultrasonic testing, the electric drive mechanism is eliminated, making the overall equipment lighter; the centering mechanism can keep the water wheel mechanism and the rail self-adaptive, ensuring the accuracy of detection;

[0022] (2) The brush is used to remove dust from the rails, and the nozzle is used to spray coupling fluid to expel air from the microstructure space of the rail surface. The water turbine body is filled with liquid and ultrasonic transducer. After the ultrasonic wave is emitted by the ultrasonic transducer, it enters the rail after passing through the internal medium of the water turbine and the water medium that is wetted on the rail surface, and detects the damage in the rail.

[0023] (3) The traveling wheels are relatively fixed, while the centering mechanism can move along the axis of the water turbine mechanism. That is, the small roller can move axially and always maintain rolling friction with the side of the rail. The traveling wheels are no longer subjected to axial thrust, so the friction is reduced and the noise is reduced.

[0024] (4) The spring can adaptively keep the water turbine mechanism centered and keep the water turbine and the rail always coupled. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1:

[0047] like Figure 1 , Figure 2 As shown, the dual-rail hand-push wheel flaw detector includes a main frame 1, a probe wheel assembly 2, a data processing assembly, a coupling water tank 5, a battery 6, and steel rails 7. The data processing assembly includes a host 3 and a computer 4. The two sets of probe wheel assemblies 2 are detachably connected to both ends of the main frame 1. The two sets of probe wheel assemblies 2 are symmetrically arranged and placed on the steel rails 7 on both sides. The host 3, battery 6, and computer 4 are installed on the main frame 1. The computer 4 is used for software operation and system display and is connected to the host 3. The host 3 is used to analyze and process the probe wheel signals and is connected to the probe wheel assembly 2. The battery 6 is used to provide power to the equipment. There are two coupling water tanks 5, which are placed on the probe wheel assembly 2 respectively.

[0048] like Figure 3 As shown, the main frame 1 includes a trapezoidal frame 11, a push rod 12, an instrument rack 13, and a quick-release clamp 14. The trapezoidal frame 11 is horizontally placed and serves as the main supporting structure, forming a rectangular frame structure. The main unit 3 and the battery 6 are both connected to the trapezoidal frame 11. The bottom of the push rod 12 is connected to the middle of the trapezoidal frame 11, and the push rod 12 is used for manual pushing. The instrument rack 13 is connected to the upper part of the push rod 12 and is used to mount the computer 4. (See also...) Figure 1 As shown, the two ends of the trapezoidal frame 11 are connected to the probe assembly 2 by two quick-release pipe clamps 14.

[0049] like Figures 4-7 As shown, the probe assembly 2 includes a probe frame mechanism 21, a water turbine mechanism 22, and a centering mechanism 23. (Refer to...) Figure 2As shown, the probe wheel frame mechanism 21 is connected to both ends of the main frame 1, the centering mechanism 23 is connected to the probe wheel frame mechanism 21, the water turbine mechanism 22 is connected to the centering mechanism 23, and the coupling water tank 5 is connected to the probe wheel frame mechanism 21.

[0050] like Figure 8 , Figure 9 As shown, the probe wheel frame mechanism 21 includes a first frame 211, a second frame 212, a traveling wheel 213, a third frame 214, a brush 215, a nozzle 216, and a wheel bracket 217.

[0051] The first frame 211 has a convex structure with one open end, the open end being the larger end of the convex structure. The first frame 211 is a flat structure, with two quick-release pipe clamps 14 connected to both sides of its closed end. The second frame 212 is mounted on the first frame 211, with its bottom ends connected to the two ends of the open end of the first frame 211. The second frame 212 is a vertical structure, and the coupling water tank 5 is connected to the second frame 212. The second frame 212 also has a protective function. Wheel brackets 217 are also connected to both sides of the first frame 211. The traveling wheels 213 are rotatably connected to the wheel brackets 217. The traveling wheels 213 are used for the overall movement of the equipment and also collect mileage encoding signals. The traveling wheels 213 are connected to the host 3, transmitting the encoding signals to the host 3 and finally displaying them on the computer 4.

[0052] The third frame 214 is connected to one end of the first frame 211 and is located on the side of the wheel bracket 217. The brush 215 is connected to the third frame 214, and the nozzle 216 is connected to the third frame 214. The nozzle 216 is connected to the coupling water tank 5 through pipes, connectors, etc. The brush 215 is used to remove dust from the rail 7, and the nozzle 216 is used to spray coupling fluid to expel air from the microstructure space on the surface of the rail 7. The water wheel body 221 is filled with liquid and an ultrasonic transducer. After the ultrasonic waves are emitted by the ultrasonic transducer, they pass through the internal medium of the water wheel and the water medium wetting the surface of the rail 7 before entering the rail 7 to detect damage in the rail 7.

[0053] In this embodiment, the probe wheel assemblies 2 are detachably connected to both sides of the main frame 1, enabling rapid assembly and disassembly. The water turbine mechanism 22 is used for detection, while the host 3 and computer 4 collect data. The overall equipment has low friction, making it easy to push and can simultaneously detect two rails 7, improving detection efficiency. Compared to ultrasonic testing of large rails 7, the electric drive mechanism is eliminated, making the overall equipment lighter. The centering mechanism 23 can maintain the self-adaptation between the water turbine mechanism 22 and the rail 7, ensuring detection accuracy.

[0054] The flaw detector in this embodiment is lightweight and compact, and features a quick-clamp design that allows for rapid assembly by just two people, facilitating operation. It has a detection speed of 5 km / h and strong detection capability. It can perform dual-track detection simultaneously without the need to apply for a time window, and the operation and detection process is simple with minimal resistance to pushing.

[0055] Example 2:

[0056] like Figure 10 , Figure 11 , Figure 12 As shown, in this embodiment, based on embodiment one, the water turbine mechanism 22 includes a water turbine body 221, a water turbine sleeve 222, a water turbine frame 223, a water turbine rotating block 224, an angle adjustment disc 225, an inclination adjustment block 226, a horizontal adjustment block 227, and a horizontal adjustment handle 228.

[0057] The turbine body 221 can be the existing technology and is connected to the main unit 3 for collecting damage signals.

[0058] Reference Figure 6 , Figure 7 , Figure 13 As shown, the two waterwheel frames 223 are connected to the centering mechanism 23. One end of the waterwheel frame 223 is provided with a bolt hole for connecting to the centering mechanism 23, and the other end is provided with a handle 2231 for holding when moving. The middle part of the waterwheel frame 223 is a U-shaped frame structure, and a rotating shaft 2232 is connected in the U-shaped frame structure. The waterwheel rotating block 224 is connected to the rotating shaft 2232.

[0059] One or two angle adjustment mechanisms are provided between the water turbine rotating block 224 and the water turbine sleeve 222. Specifically, the side of the water turbine rotating block 224 has a threaded post that can be threadedly connected to the water turbine sleeve 222. An angle adjustment disc 225 is connected to the outside of the connection between the threaded post and the water turbine sleeve 222. The angle adjustment disc 225 has an arc-shaped groove. The top of the side of the water turbine rotating block 224 is connected to a first bolt 2241, which can pass through the arc-shaped groove. A first nut 2242 is locked to the first bolt 2241. The angle adjustment disc 225 is used to achieve left and right adjustment. That is, when it is necessary to adjust the water turbine body 221 left and right, the water turbine sleeve 222 and the water turbine rotating block 224 are rotated to a suitable position, and then locked by the first bolt 2241 and the first nut 2242.

[0060] It should be noted that the waterwheel rotating blocks 224 at both ends of the waterwheel sleeve 222 can be equipped with angle adjustment mechanisms, or only one waterwheel rotating block 224 can be set.

[0061] In this embodiment, the water turbine body 221 is adjusted by a tilt adjustment mechanism, which is mainly implemented by a tilt adjustment block 226. Figure 12, Figure 13 As shown, the water turbine sleeve 222 is a rectangular frame. The two ends of the rotating shaft of the water turbine body 221 are connected to the two sides of the water turbine sleeve 222 respectively. The left end of the rotating shaft of the water turbine body 221 is fixedly connected to the water turbine sleeve 222, a pressure block 2221, and the second bolt 2222. The right end of the rotating shaft of the water turbine body 221 is not only connected to the water turbine sleeve 222, but also extends into the tilt adjustment block 226 and can be fixedly connected to the tilt adjustment block 226. Two arc-shaped waist grooves are provided on each side of the tilt adjustment block 226. The four arc-shaped waist grooves are symmetrical in the upper, lower, left, and right directions. The third bolt 2261 fixes the tilt adjustment block 226 and the water turbine sleeve 222 together through the arc-shaped waist grooves. A fourth bolt 2262 is also provided in the vertical direction. The fourth bolt 2262 can fix the rotating shaft of the water turbine body 221 and the tilt adjustment block 226 together.

[0062] In this embodiment, the water turbine body 221 is also centered by a centering adjustment mechanism, specifically achieved by a horizontal adjustment block 227 and a horizontal adjustment handle 228. The horizontal adjustment block 227 is connected to the outside of the tilt adjustment block 226 and fixed by a fifth bolt 2271. A long slot is opened on one side of the horizontal adjustment block 227. The middle part of the horizontal adjustment handle 228 is inserted into the long slot and then engaged in the long slot. One end of the horizontal adjustment handle 228 is a threaded post that can be threadedly connected to the rotating shaft of the water turbine body 221, and the other end is a screw head for manually screwing to adjust the length of the threaded connection section between the horizontal adjustment handle 228 and the rotating shaft of the water turbine body 221, thereby achieving centering adjustment.

[0063] In this embodiment, the angle of the water turbine body 221 is adjusted by means of an angle adjustment mechanism, an inclination adjustment mechanism, and a centering adjustment mechanism, so that the water turbine body 221 is always effectively coupled with the rail 7.

[0064] Specifically, one end of the rotating shaft of the waterwheel body 221 can be connected between one side of the waterwheel sleeve 222 and the pressure block 2221, and the other end can be inserted into the other side of the waterwheel sleeve 222 and the inside of the tilt adjustment block 226. The waterwheel body 221 can be centered by turning the horizontal adjustment handle 228, and then the waterwheel body 221 and the waterwheel sleeve 222 can be fixed together by the fourth bolt 2262 and the second bolt 2222. The front-to-back angle of the waterwheel body 221 can be adjusted by the tilt adjustment block 226, and then the third bolt 2261 can be tightened. The left-to-right angle of the waterwheel body 221 can be adjusted by the angle adjustment disc 225, and then the first bolt 2241 can be tightened. This is only a suggested adjustment method. Depending on the actual use, the front-to-back, left-to-right, and centering adjustments can be made multiple times and the adjustment sequence can be changed to achieve the optimal state.

[0065] In this embodiment, the traveling wheel 213 is relatively fixed, while the centering mechanism 23 can move along the axial direction of the water wheel mechanism 22. That is, the small roller 232 can move axially and always maintain rolling friction with the side of the rail 7. The traveling wheel 213 is no longer subjected to axial thrust, so the friction is reduced and the noise is reduced. At the same time, this embodiment reduces the number of electric drive parts, making the whole unit lighter and more flexible. Lightweight and flexible design is essential for quick movement and loading / unloading of rails. The better the flexibility, the better the centering effect during movement.

[0066] Example 3:

[0067] like Figure 6 , Figure 7 As shown, the centering mechanism 23 includes a centering fixing plate 231, at least two sets of elastic sliding components, and two small rollers 232. The at least two sets of elastic sliding components are connected to the probe wheel frame mechanism 21. The centering fixing plate 231 is connected to the elastic sliding components, and the two small rollers 232 are connected to the bottom of both ends of the centering fixing plate 231. During detection, the small rollers 232 rest against the side of the rail 7, serving as the centering limit for the water turbine mechanism 22.

[0068] In this embodiment, there are two elastic sliding components. Each elastic sliding component includes a mounting base 233, a sliding rod 234, a spring 235, and a slider 236. Each elastic sliding component is equipped with two mounting bases 233, and both mounting bases 233 are connected to the first frame 211 in the probe wheel frame mechanism 21 by bolts. The two mounting bases 233 are arranged relatively spaced apart. The two ends of the sliding rod 234 are fixedly connected to the mounting bases 233, and the slider 236 is slidably connected to the sliding rod 234. The spring 235 is sleeved on the sliding rod 234, and its two ends abut against the mounting base 233 and the slider 236, which are respectively away from the water turbine mechanism. The bottom of the slider 236 is connected to the centering fixing plate 231 by bolts. The water turbine frame 223 is connected to the centering fixing plate 231.

[0069] That is, the adaptive performance of the spring 235 enables the centering fixed plate 231 to move adaptively, thereby enabling the water turbine frame 223 to move adaptively, thus keeping the water turbine mechanism 22 centered and keeping the water turbine body 221 and the rail 7 always coupled.

[0070] In this embodiment, the centering mechanism 23 further includes guide blocks 237. Two guide blocks 237 are provided on both sides of each small roller 232. The guide blocks 237 are used to enable the overall equipment to pass through the railway junction.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
