Description

Technical Field

[0001] The utility model relates to the field of rail wear detection, in particular to a collection device. Background Art

[0002] With the rapid development of railway transportation, the safety and stability of railway transportation become particularly important. As an important part of the railway, the quality and condition of the rail directly affect the running safety of the train. During the long-term use of the rail, due to the high-speed running and frequent use of the train, wear phenomenon will inevitably occur. The wear of the rail will not only affect the smooth running of the train, but also may cause a series of safety accidents. Therefore, it is of great significance to detect the wear condition of the rail in real time and accurately for ensuring the safe operation of the railway.

[0003] Traditional rail wear detection methods mainly rely on manual measurement. This method often requires contact measurement and has a single measurement angle, which is vulnerable to the influence of the surrounding environment. With the development of technology, rail wear detection methods based on laser and image processing technology have gradually been applied. These methods usually obtain the wear information on the rail surface through laser scanning and image capture, and achieve accurate calculation of wear through data processing and analysis. However, in current use, laser scanning often cannot detect at a fixed position and angle, which is likely to cause errors. Summary of the Utility Model

The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or selectively mutually exclusive embodiment with other embodiments.

[0028] Embodiment 1

[0029] Referring to Figures 1 to 6 , which is the first embodiment of the present utility model. This embodiment provides a collection device, including a collection unit 100, which includes a collection housing 101, a first camera 102, a second camera 103, and a line laser 104 disposed inside the collection housing 101; a mounting frame 200, the mounting frame 200 is wrapped outside the collection unit 100, including an upper housing 201, a lower housing (202) disposed on the outer wall of the upper housing 201, a limiting boss 201a disposed on the outer wall of the upper housing 201, and a limiting groove 202a disposed on the outer wall of the lower housing 202 and cooperating with the limiting boss 201a; a driving unit 300, the driving unit 300 is disposed below the mounting frame 200, including a vehicle body frame 301 and driving wheels 302 disposed on the vehicle body frame 301.

[0030] Among them, the line laser 104 is selected as a one-dimensional line laser with a wavelength of 405 nm, and is installed inside the collection housing 101. The line laser 104 has high brightness and high stability and can work stably under various lighting conditions; the first camera 102 and the second camera 103 are located on the left and right sides of the line laser 104. It should be noted that both the first camera 102 and the second camera 103 are industrial cameras, which are respectively installed on the inner walls of both sides of the collection housing 101. The industrial cameras have high resolution and high-speed shooting functions and can capture the subtle changes on the surface of the steel rail in real time; the inside of the collection housing 101 is sufficient to accommodate the line laser 104, the first camera 102, and the second camera 103; the central axes of the first camera 102, the second camera 103, and the line laser 104 are on the same horizontal plane inside the collection housing 101. It should be noted that the central axis refers to the line connecting the head and tail center points of a long strip-shaped device; there is a space inside the upper housing 201 and the lower housing 202 to accommodate the collection unit 100. There is one collection unit 100 inside each of the two sides of the mounting frame 200. The limiting boss 201a of the upper housing 201 can be accommodated in the limiting groove 202a of the lower housing 202 so that the upper housing 201 and the lower housing 202 can be combined into one body; the mounting frame 200 is fixedly connected to the driving unit 300.

[0031] In use, place two acquisition units 100 inside the left and right sides of the mounting frame 200. Fit the limit boss 201a into the limit groove 202a to integrate the upper housing 201 and the lower housing 202. Then, after fixedly connecting the mounting frame 200 to the drive unit 300, place the entire device on the railway track and start it. When the drive unit 300 drives the entire device to move, the line laser 104 generates a continuous laser line on the surface of the rail. As the drive unit 300 moves, this laser line forms a series of continuous mapped images on the surface of the rail. The first camera 102 and the second camera 103 respectively capture these mapped images in real time from different angles.

[0032] In summary, during use, this design realizes non-contact measurement, captures the contour of the laser line from two different angles (left and right), has the ability to resist environmental interference, provides fixed positions and angles, keeps the laser beam consistent with the camera view angle, reduces errors, and improves the acquisition accuracy.

[0033] Embodiment 2

[0034] Refer to Figures 1 to 6 , which is the second embodiment of the present utility model. The acquisition housing 101 is provided with data interfaces 105. There are two data interfaces 105 on the acquisition housing 101, corresponding to the first camera 102 and the second camera 103; a line laser power interface 104a is provided on the acquisition housing 101.

[0035] Among them, the three data interfaces 105 are located on the same surface of the acquisition housing 101. The first camera 102 and the second camera 103 transmit data through the two data interfaces 105, and the line laser 104 is connected to an external power supply through the line laser power interface 104a.

[0036] Furthermore, the included angle between the central axis of the first camera 102 and the central axis of the line laser 104 is 45°; the included angle between the central axis of the second camera 103 and the central axis of the line laser 104 is 45°.

[0037] Among them, the first camera 102 and the second camera 103 are distributed on both sides of the line laser 104. It should be noted that the central axis refers to the line connecting the center points of the head and tail of a long strip-shaped device. When the central axes of the first camera 102, the second camera 103 and the line laser 104 are on the same horizontal plane, the included angle between the central axis of the first camera 102 and the central axis of the second camera 103 is 90°. When all the above position relationships are satisfied, the first camera 102, the second camera 103 and the line laser 104 are all located inside the acquisition housing 101. The included angle between the central axis of the first camera 102 and the central axis of the line laser 104 is 45°, and the included angle between the central axis of the second camera 103 and the central axis of the line laser 104 is 45°, which enables the system to more accurately measure the shape and size of the rail, ensuring the symmetry and consistency of image capture, observing from multiple angles to reduce the blind area of data acquisition, and reducing the occlusion problem encountered during the data acquisition process by the camera. The included angle between the central axes of the first camera 102 and the second camera 103 is 90°, which also ensures a sufficient shooting range while concentrating on shooting the irradiation result of the line laser 104.

[0038] Furthermore, the limiting boss 201a and the limiting groove 202a are completely matched in shape; the upper housing 201 and the lower housing 202 can be completely fitted through the limiting boss 201a and the limiting groove 202a.

[0039] Among them, when the limiting boss 201a and the limiting groove 202a are completely matched in shape, the fitting of the upper housing 201 and the lower housing 202 can achieve a perfect fit effect.

[0040] Furthermore, a first baffle 201b is provided inside the upper housing 201, and a second baffle 202b is provided inside the lower housing 202; the space surrounded by the first baffle 201b and the second baffle 202b can accommodate the acquisition housing 101.

[0041] Among them, the first baffle 201b and the second baffle 202b are respectively a baffle combination composed of two baffles. The first baffle 201b and the original housing of the upper housing 201 can enclose a space that can accommodate half of the acquisition unit 100 and whose shape completely matches that of the acquisition unit 100; the second baffle 202b and the original housing of the lower housing 202 can enclose a space that can accommodate half of the acquisition unit 100 and whose shape completely matches that of the acquisition unit 100; when the upper housing 201 and the lower housing 202 are fitted through the limiting boss 201a and the limiting groove 202a, the first baffle 201b, the second baffle 202b, and the original housings of the upper housing 201 and the lower housing 202 enclose a space that can exactly accommodate the acquisition unit 100.

[0042] Further, one first baffle 201b is provided on each of the two sides inside the upper housing 201; one second baffle 202b is provided on each of the two sides inside the lower housing 202.

[0043] Among them, one first baffle 201b is provided on each of the left and right sides of the upper housing 201, aiming to protect the acquisition units 100 on both sides; one second baffle is provided on each of the left and right sides of the lower housing 202, aiming to protect the acquisition units 100 on both sides; so that the acquisition unit 100 will not have a failure of leaving the working area inside the mounting rack 200.

[0044] Further, a first through groove 201c is provided on the side of the upper housing 201, and a second through groove 202c is provided on the side of the lower housing 202.

[0045] Among them, both the first through groove 201c and the second through groove 202c are groove groups composed of three grooves; when the upper housing 201 and the lower housing 202 are fitted together, the first through groove 201c and the second through groove 202c will be combined into three slots that can allow the cameras of the first camera 102 and the second camera 103 to shoot results and the line laser 104 to emit laser to the object to be measured.

[0046] Further, one first through groove 201c is provided on each of the two sides of the upper housing 201; one second through groove 202c is provided on each of the two sides of the lower housing 202; the lower housing 202 is provided with first screw holes 202d, and four first screw holes 202d are provided on the lower housing 202d.

[0047] Among them, in the case of the first through groove 201c and the second through groove 202c on the left and right sides, there are slots on both the left and right sides to allow the cameras of the first camera 102 and the second camera 103 on the acquisition unit 100 inside the mounting rack 200 to shoot, and the line laser 104 to emit laser to the object to be measured; the first screw holes 202d on the lower housing 202 function to be bolted to the vehicle body frame 301, and the four first screw holes 202d improve the stability of the mounting rack 200 on the driving unit 300.

[0048] Further, a vehicle body front axle 301a and a vehicle body rear axle 301b are provided on the vehicle body frame 301, and a second screw hole 301c matching the first screw hole 202d is provided on the vehicle body frame 301.

[0049] Among them, the front axle 301a of the vehicle body supports the vehicle weight, enabling the vehicle to drive stably on the railway track. The front axle 301a of the vehicle body transmits the driving force and distributes it to the two front wheels, enabling the vehicle to drive and control the driving direction. The front wheels are steered by the steering gear on the front axle 301a of the vehicle body to achieve the steering function of the vehicle. The front axle 301a of the vehicle body absorbs impacts, and the shock absorber damping elements on the front axle 301a of the vehicle body can effectively absorb these impacts to protect the components inside the acquisition unit 100. The design and stiffness of the front axle 301a of the vehicle body improve the stability of the vehicle and reduce the risk of accidents. The rear axle 301b of the vehicle body supports the vehicle weight, enabling the vehicle to drive stably on the railway track. The rear axle 301b of the vehicle body obtains the driving force through the power source, enabling the vehicle to drive. The rear axle 301b of the vehicle body absorbs impacts, and the shock absorber damping elements on the rear axle 301b of the vehicle body can effectively absorb these impacts to protect the components inside the acquisition unit 100. The design and stiffness of the rear axle 301b of the vehicle body improve the stability of the vehicle and reduce the risk of accidents. The number of the second screw holes 301c is the same as that of the first screw holes 202d, which is four. The positions of the second screw holes 301c correspond to those of the first screw holes 202d one by one. The screw holes are selected for better stability. In the case of using through holes, since there is no thread restriction, the fixed connection is entirely achieved by the friction between the nut and the components. Therefore, bolt connection is selected.

[0050] Further, the driving wheels 302 can be divided into front wheels 302a and driving wheels 302b.

[0051] Among them, the front wheels 302a are connected to the front axle 301a of the vehicle body, and the driving wheels 302b are connected to the rear axle 301b of the vehicle body.

[0052] During use, place the two acquisition units 100 into the space enclosed by the second baffle 202b and the lower housing 202. Place the lower housing 202 on the vehicle body frame 301, align the first screw holes 202d with the second screw holes 301c, insert bolts and lock them with nuts. Place the limit boss 201a into the limit groove 202a to integrate the upper housing 201 with the lower housing. During this process, the cameras of the first camera 102, the second camera 103 and the line laser 104 and the emitting head must face the large empty groove formed by the first through groove 201c and the second through groove 202c. Place the entire device on the railway track. Both the front wheels 302a and the driving wheels 302b are located on the railway track. After starting, when the driving unit 300 drives the entire device to move, the line laser 104 generates a continuous laser line on the surface of the rail. As the driving unit 300 moves, this laser line will form a series of continuous mapping images on the surface of the rail. The first camera 102 and the second camera 103 respectively capture these mapping images in real time from different angles.

[0053] In summary, during use, this design achieves non-contact measurement, captures the profile of the laser line from two different angles (left and right), has the ability to resist environmental interference, provides a fixed position and angle, keeps the laser beam consistent with the camera's perspective, reduces errors, and improves the acquisition accuracy.
