[0027] The present invention provides a wheel detection device 100 .

[0028] In the embodiment of the present invention, Figures 1 to 4 As shown, the wheel detection device 100 includes: a substrate 10, a first laser sensor 20 and a second laser sensor 30, wherein the first laser sensor 20 is movably arranged in the substrate 10, and the first laser sensor 20 is used to emit and receive a first detection laser outside the substrate 10; the second laser sensor 30 is fixed in the substrate 10, and the second laser sensor 30 is used to emit and receive a second detection laser outside the substrate 10; wherein the first laser sensor 20 can move along a detection direction perpendicular to the first laser sensor 20, and the detection direction of the first laser sensor 20 is perpendicular to the detection direction of the second laser sensor 30.

[0029] Specifically, the first laser sensor 20 and the second laser sensor 30 are sensors that use laser technology for measurement. They are generally composed of a laser emitting end, a laser receiving end, and a measuring circuit. They can achieve non-contact long-distance measurement, with fast speed, high accuracy, large range, strong resistance to light and electrical interference, etc. When measuring the distance, the laser is aimed at the target and emitted, and its round-trip time is measured, and then multiplied by the speed of light to obtain the round-trip distance. Taking the first laser sensor 20 as an example, the detection end of the first laser sensor 20 includes a first emitting end and a first receiving end. The first emitting end emits a first detection laser to the outside of the substrate 10. The first detection laser reaches the target (wheel) and is reflected back and received by the first receiving end, thereby realizing the distance measurement function. Among them, in order to facilitate the emission and reception of the first detection laser and the second detection laser, an opening or a light-transmitting plate can be correspondingly set on the substrate 10.

[0030] It should be noted that the detection direction of the first laser sensor 20 here refers to the direction in which the detection end of the first laser sensor 20 is facing, that is, the extension direction of the symmetric center line between the first detection laser emitted by the first laser sensor 20 and the first detection laser received; similarly, the detection direction of the second laser sensor 30 here refers to the direction in which the detection end of the second laser sensor 30 is facing, that is, the extension direction of the symmetric center line between the second detection laser emitted by the second laser sensor 30 and the second detection laser received.

[0031] The wheel detection device 100 of the present invention can at least detect the tread of the wheel and the inner distance of the wheelset. The specific detection method is as follows: the substrate 10 is positioned on the wheel to be detected, and the detection direction of the first laser sensor 20 is directed toward the tread of the wheel, and the detection direction of the second laser sensor 30 is directed toward the wheel on the other side opposite to the wheel on the side. In this way, the first laser sensor 20 emits a first detection laser to the tread of the wheel to be detected, and receives the first detection laser reflected by the tread of the wheel to be detected. At the same time, the first laser sensor 20 is controlled to move along the detection direction perpendicular to the first laser sensor 20, so that the first detection laser of the first laser sensor 20 can scan the tread profile of the entire wheel to be detected, thereby obtaining the relevant parameters of the tread of the wheel to be detected, including the rim height, rim thickness and rim comprehensive value; and the second detection laser is emitted to the wheel on the opposite side by the second laser sensor 30, and the second detection laser reflected by the wheel on the opposite side is received, so that the inner distance of the wheelset between the wheel to be detected and the wheel on the opposite side can be obtained.

[0032] After obtaining the test data of various parameters, the test results can be compared with the range of the wheel detection technical standards to determine whether the various parameters of the wheel meet the standards, so as to facilitate technicians to repair or replace the wheel.

[0033] Therefore, in the technical solution of the present invention, by arranging the first laser sensor 20 to be movable along a detection direction perpendicular to the first laser sensor 20, and the detection direction of the first laser sensor 20 is perpendicular to the detection direction of the second laser sensor 30, at least the wheel tread detection function and the wheelset inner distance detection function can be realized, the detection functions are diverse, the detection method is convenient, and the wheel detection device 100 of the present invention has a simple structure, low cost, is lightweight and portable, and is suitable for popularization and use.

[0034] In one embodiment of the present invention, please refer to Figures 1 to 4 The base 10 includes: a first mounting portion 11 and a second mounting portion 12, the first laser sensor 20 is arranged in the first mounting portion 11, and the first laser sensor 20 is used to emit and receive the first detection laser outside the first mounting portion 11; the second laser sensor 30 is arranged in the second mounting portion 12, and the second laser sensor 30 is used to emit and receive the second detection laser outside the second mounting portion 12; wherein, the first mounting portion 11 and the second mounting portion 12 are vertically connected, and the detection direction of the first laser sensor 20 is toward the side where the second mounting portion 12 extends, and the detection direction of the second laser sensor 30 is away from the side where the first mounting portion 11 extends.

[0035] In this embodiment, the first mounting portion 11 extends in the horizontal direction, and the second mounting portion 12 extends in the longitudinal direction. One end of the first mounting portion 11 is connected to one end of the second mounting portion 12, and the two form a right angle. The structure is compact, convenient to hold and carry. The first laser sensor 20 and the second laser sensor 30 are respectively installed in the first mounting portion 11 and the second mounting portion 12. At the same time, the detection direction of the first laser sensor 20 is toward the area where the right angle range is located, and the detection direction of the second laser sensor 30 is away from the area where the right angle range is located. In this way, the first mounting portion 11 provides a moving space for the first laser sensor 20, and the first laser sensor 20 can move along the length direction of the first mounting portion 11. Moreover, when the first mounting portion 11 is attached to the wheel tread and the second mounting portion 12 is attached to the side of the wheel, so that the right-angle base 10 is positioned on the wheel, the first detection laser emitted by the first laser sensor 20 is aimed at the wheel tread, and the second detection laser emitted by the second laser sensor 30 is aimed at the opposite wheel. The first detection laser and the second detection laser do not affect each other, and the wheel tread detection and the wheelset inner distance detection can be performed on the wheel at the same time. The detection method is convenient and the detection efficiency can be improved.

[0036] In one embodiment of the present invention, please refer to Figures 1 to 4The wheel detection device 100 also includes: a first positioning member 41, a pull rod 42 and an elastic reset member 43, the first positioning member 41 is slidably provided on the surface of the second mounting portion 12, and the first positioning member 41 and the first mounting portion 11 extend in the same direction; the pull rod 42 extends from the inside of the second mounting portion 12 to the outside of the second mounting portion 12, and the pull rod 42 can slide along the length direction of the second mounting portion 12, the first positioning member 41 is fixedly connected to the pull rod 42; the elastic reset member 43 is sleeved on the pull rod 42, and the two ends of the elastic reset member 43 are respectively abutted against the first positioning member 41 and the second mounting portion 12.

[0037] In this embodiment, a mounting assembly is also provided on the base 10. Based on the right-angled first mounting portion 11 and the second mounting portion 12, the base 10 can be positioned on the wheel through the mounting assembly. Specifically, the mounting assembly includes a first positioning member 41, a pull rod 42 and an elastic reset member 43. A slide groove 124 for the first positioning member 41 to slide is provided on the surface of the second mounting portion 12. A slideway 125 for the pull rod 42 to slide is provided inside the second mounting portion 12. A bushing is sleeved on the pull rod 42. The pull rod 42 slides along the slideway 125, so that the first positioning member 41 can slide in the slide groove 124, and the pull rod 42 can be reset by the elastic reset member 43. The first positioning member 41 is a positioning block, and the elastic reset member 43 is a coil spring. When the base 10 is installed on the wheel, first pull the rod 42 to extend the rod 42 along the second mounting portion 12, and drive the first positioning member 41 to slide downward, so that the distance between the first mounting portion 11 and the first positioning member 41 is greater than the distance between the wheel tread and the positioning point of the inner ring of the wheel; then, fit the first mounting portion 11 to the tread of the wheel, and fit the second mounting portion 12 to the side of the wheel to complete the pre-positioning; finally, release the rod 42, and through the rebound effect of the elastic reset member 43, position the first positioning member 41 to the positioning point of the inner ring of the wheel, thereby completing the complete positioning of the base 10 and the wheel. Among them, the detection direction of the first laser sensor 20 is toward the side where the first positioning member 41 is located, and the second laser sensor 30 is facing away from the side where the first positioning member 41 is located, so that the wheel can be detected on the wheel tread and the inner distance of the wheelset at the same time. This technical solution makes the detection more convenient and improves the detection accuracy by positioning the base 10 on the wheel and then detecting it.

[0038] In one embodiment of the present invention, please refer to Figures 1 to 4 The wheel detection device 100 further includes: two second positioning members 44 , which are fixedly mounted on a side surface of the first mounting portion 11 facing the first positioning member 41 , and the two second positioning members 44 are symmetrically distributed with respect to the first positioning member 41 .

[0039] In this embodiment, the mounting assembly further includes two second positioning members 44, which are positioning blocks. The two second positioning members 44 cooperate with the first positioning member 41 to further position the base 10. Specifically, during the process of mounting the base 10 on the wheel, when the first mounting portion 11 is attached to the tread of the wheel, the two second positioning members 44 protruding from the surface of the first mounting portion 11 are in contact with the tread of the wheel. By adjusting the two points at the top of the wheel tread to fit with the two second positioning members 44 respectively, and cooperating with the first positioning member 41 attached to the positioning point of the inner ring of the wheel, the three-point positioning of the base 10 and the wheel can be achieved, which can further improve the accuracy and firmness of the positioning of the base 10, thereby further improving the detection accuracy.

[0041] In this embodiment, a magnetic member 45 is installed on the surface of the second mounting portion 12 facing the right angle area. The magnetic member 45 is a magnet. Specifically, when the base 10 is installed on the wheel, when the second mounting portion 12 is attached to the side of the road, the magnetic member 45 on the side of the second mounting portion 12 is attached to the metal side of the wheel, so that the second mounting portion 12 is adsorbed on the side of the wheel. In this way, the base 10 can be more firmly positioned on the wheel, which is convenient for completing subsequent detection operations.

[0042] In one embodiment of the present invention, please refer to Figures 1 to 4 The first mounting portion 11 is provided with a first mounting cavity 111 and a first opening 112 connected to the first mounting cavity 111, the first laser sensor 20 is arranged in the first mounting cavity 111, and the detection end of the first laser sensor 20 faces the first opening 112; the second mounting portion 12 is provided with a second mounting cavity 121 and a second opening 122 connected to the second mounting cavity 121, the second laser sensor 30 is arranged in the second mounting cavity 121, and the detection end of the second laser sensor 30 faces the second opening 122; wherein, the first opening 112 faces the side where the first positioning member 41 is located, and the second opening 122 faces away from the side where the first positioning member 41 is located.

[0043] In this embodiment, the first mounting portion 11 and the second mounting portion 12 are both hollow structures, the first opening 112 of the first mounting portion 11 faces the area where the right angle range is located, and the second opening 122 of the second mounting portion 12 faces away from the area where the right angle range is located. The first laser sensor 20 is movably mounted in the first mounting cavity 111, and the first laser sensor 20 transmits and receives the first detection laser through the first opening 112.

[0045] In this embodiment, taking the first laser sensor 20 and the first light-transmitting plate 113 as an example, by arranging the first light-transmitting plate 113 at the first opening 112, the first laser sensor 20 can be protected without affecting the emission and reception of the first detection laser by the first laser sensor 20, so as to prevent foreign objects from entering the first installation cavity 111 and causing damage to the first laser sensor 20, and can prevent moisture and dust, which is conducive to extending the service life of the first laser sensor 20. The function of the second light-transmitting plate 123 is the same as that of the first light-transmitting plate 113, and will not be repeated.

The distance value detected at this position can be converted into the diameter data corresponding to the wheel according to the known inner diameter of the wheel of this type. The converted wheel diameter is compared with the preset diameter of the wheel to understand the degree of wheel tread wear. When the wheel diameter is less than the test standard, the wheel needs to be repaired or replaced. In this technical solution, while realizing the wheel tread detection function and the wheelset inner distance detection function, the wheel diameter detection function can also be realized, making the wheel detection device 100 of the present invention more versatile.
