[0042] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0043] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0044] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0045] In addition, the terms "first", "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, the meaning of "multiple groups" is two groups or more, the meaning of "multiple pieces" is two pieces or more, and the meaning of "several" is one or more, unless otherwise specifically limited.

[0046] In important fields such as railways and urban rail transit, steel rails, as the core component of the track structure, play an irreplaceable key role. It not only provides precise guidance for the operation of the train, ensuring that the train travels safely and stably along the established route, but also bears the weight of the train itself and all the loads such as goods and passengers, and effectively transmits these loads to the foundation structure.

[0047] During the operation of the train, the steel rail is constantly subjected to great pressure and impact force. Due to long-term exposure to this complex and harsh mechanical environment, if the steel rail has quality defects such as cracks and pores, these defects are likely to gradually expand and spread under the continuous action of alternating loads. When the defects develop to a certain extent, they may cause the steel rail to suddenly break. Once the steel rail breaks, the train will lose reliable support, and it is extremely easy to cause catastrophic accidents such as derailment and overturning, which often cause serious casualties and huge property losses.

[0048] At the same time, the flatness of the track surface composed of steel rails is also of great significance to the smoothness and safety of train operation. If the track surface is not flat, the train will inevitably produce violent vibration and shaking during operation. This not only greatly reduces the comfort of passengers, but also significantly exacerbates the wear and tear between the wheels and the steel rails. Long-term excessive wear and tear will significantly shorten the service life of track components, increasing track maintenance costs and safety hazards.

[0049] In view of the above situation, it is particularly important to conduct comprehensive and strict quality detection on the steel rail before it is put into use. Through quality detection, the surface quality of the steel rail is strictly controlled to ensure that the geometric dimension accuracy of the steel rail meets the standard requirements, thereby providing a solid guarantee for the safe operation of the train on a smooth track.

[0050] In the existing related technology, the automatic detection device for steel rails has certain limitations. Generally, such devices can only detect the quality of the side surface of the steel rail and cannot achieve comprehensive detection of all areas of the steel rail. For those parts not covered by the automatic detection device, manual detection with detection instruments is still needed to ensure that the overall quality of the steel rail meets the specified standards. However, this detection method relies on a large amount of manual operation, not only resulting in a huge amount of manual work, but also severely restricting the improvement of detection efficiency, making it difficult to meet the needs of the modern railway transportation industry for efficient and accurate detection.

[0051] Therefore, based on this, the embodiments of the present application provide a steel rail detection device to solve the above problems.

[0055] It should be noted that the end portion detection mechanism 2 can comprise detection elements used for detecting the quality of the rail 100, and the end portion detection mechanism 2 can perform quality checking on the end surface of the rail 100, for example, the end portion detection mechanism 2 can perform surface defect checking on the end portion of the rail 100, and can also perform contour shape checking, size checking and asymmetry checking on the end portion of the rail 100.

[0056] The rail 100 detection device provided by the present application comprises the end portion detection mechanism 2 and the peripheral portion detection mechanism 3 arranged on the base 1, the end portion detection mechanism 2 can perform quality detection on the end surface of the rail 100, and the peripheral portion detection mechanism 3 can perform quality detection on the top surface, the side surface and the bottom surface of the rail 100, so that the rail 100 detection device can obtain the size and the appearance defect information of the end surface of the rail 100 and the size and the appearance defect information of the peripheral portion of the rail 100, so as to help reduce the labor work amount and improve the detection efficiency of the rail 100.

[0057] In some embodiments, the end detection mechanism 2 comprises a first detector 21 slidably arranged on the base 1 along a first direction, the first detector 21 has a first position and a second position, when the first detector 21 is at the first position, the first detector 21 is opposite to the end position of the rail 100 to detect the quality of the end of the rail 100, the first detector 21 can be moved to the second position along the first direction to enable the rail 100 to move along a second direction to enter or exit the rail 100 detection device, wherein the second direction is parallel to the length direction of the rail 100, and the first direction is perpendicular to the second direction.

[0058] It should be noted that the second direction can be the X-axis direction shown in the figure, and the first direction can be the direction parallel to the plane formed by the Z-axis and the X-axis shown in the figure, and in some embodiments, the first direction can be the Z-axis direction shown in the figure.

[0059] It should be noted that in some embodiments, a driving member for driving the rail 100 to move along the second direction can be arranged outside the rail 100 detection device, or a driving member for driving the rail 100 to move can be arranged inside the rail 100 detection device, that is, the power for moving the rail 100 along the second direction can be provided by the rail 100 detection device or can be provided by the rail 100 detection device.

[0060] It should be noted that the first detector 21 can include one or more of a two-dimensional laser scanner, a three-dimensional laser scanner, an electromagnetic ultrasonic detector, and an ultrasonic flaw detector.

[0061] Enabling the rail 100 to move relative to the rail 100 detection device can reduce the size of the rail 100 detection device in the second direction, so that the rail 100 detection device can be smaller than the length of the rail 100, so that the space occupied by the rail 100 detection device can be reduced; slidingly arranging the first detector 21 on the base 1 can change the position of the first detector 21 during the detection of the rail 100, when the end face of the rail 100 needs to be detected, the first detector 21 can be moved to the first position, so that the first detector 21 can be opposite to the end position of the rail 100 to realize the quality detection of the end of the rail 100, so as to ensure the accuracy of the detection result, when the rail 100 needs to be moved to adjust the position of the rail 100, the first detector 21 can be moved to the second position, at this time, the rail 100 can move along the second direction, and the first detector 21 will not block the movement of the rail 100, so as to reduce the possibility of collision between the rail 100 and the first detector 21 during the movement of the rail 100.

[0062] In some embodiments, the moving speed of the steel rail 100 can range from 0.8 m / s to 2 m / s, and for example, the moving speed of the steel rail 100 can be 0.8 m / s, 1.0 m / s, 1.2 m / s, 1.4 m / s, 1.6 m / s, 1.8 m / s, or 2 m / s; and the detection accuracy of the steel rail 100 detection device can be ±0.1 mm.

[0063] In some embodiments, the steel rail 100 detection device further comprises a sensing assembly in communication connection with the end detection mechanism 2 and the peripheral detection mechanism 3, the sensing assembly comprising a first sensor and a second sensor arranged at intervals along the second direction on the base 1, the first sensor and the second sensor being configured to detect the position information of the steel rail 100 and send the position information to the end detection mechanism 2 and the peripheral detection mechanism 3, so that the end detection mechanism 2 and the peripheral detection mechanism 3 can confirm the defect position of the steel rail 100.

[0064] It should be noted that the first sensor and the second sensor can be a high-precision encoder, which is a precision measuring device capable of accurately converting physical quantities such as position, speed, and angle of mechanical movement into digital signals or electrical signals. The high-precision encoder usually works based on photoelectric, magneto-electric, or capacitive sensing principles. For example, the photoelectric encoder has a code disc with transparent and non-transparent areas inside. When the code disc rotates with the mechanical shaft, the light emitted by the light source passes through the transparent area of the code disc and is received by the photosensitive element and converted into an electrical signal. By counting and processing these electrical signals, the rotation angle, position, and speed of the shaft can be accurately measured. In addition, the first sensor and the second sensor can also be an infrared position detector, an ultrasonic detector, a Doppler position and speed detector, etc.

[0065] The sensing assembly is in communication connection with the end detection mechanism 2 and the peripheral detection mechanism 3, which can be achieved by wired connection such as wires, or by wireless connection such as Bluetooth, Wi-Fi, mobile network, etc. The detection results of the sensing assembly can be transmitted to the end detection mechanism 2 and the peripheral detection mechanism 3, respectively, and the end detection mechanism 2 and the peripheral detection mechanism 3 can confirm the position of the defect on the steel rail 100 according to the position information, thereby facilitating the repair of the defect by the staff.

[0067] The first driving member 22 is arranged to drive the first detector 21 to move, and the rail 100 detection device can automatically drive the first detector 21 to move to adjust the position of the first detector 21, so that the automation degree of the rail 100 detection device can be improved, and the labor workload in the rail 100 detection operation process can be reduced.

[0068] In some embodiments, the first driving member 22 can be one of a motor, a pneumatic cylinder, and a hydraulic cylinder.

[0069] Of course, in other embodiments, the position of the first detector 21 can be adjusted by manually moving the first detector 21, so that the first detector 21 can realize position switching.

[0070] Referring to Figure 2 and Figure 3 In some embodiments, the end detection mechanism 2 further comprises a first sliding rail 23 and a first sliding block 24 slidably connected to the first sliding rail 23, the first sliding rail 23 is connected to the base 1, the length direction of the first sliding rail 23 is parallel to the first direction, and the first sliding block 24 is connected to the first detector 21. When the first sliding block 24 slides along the first sliding rail 23, the movement of the first detector 21 can be guided, so that the position deviation of the first detector 21 during movement can be reduced, thereby helping to improve the detection accuracy of the first detector 21.

[0071] In some embodiments, the first direction can be the Z-axis direction shown in the figure, and the first detector 21 can move close to or away from the bottom plate 11 of the base 1.

[0072] Referring to Figure 4 In some embodiments, the end detection mechanism 2 can include two first detectors 21, and the two first detectors 21 can respectively detect the quality of the two end faces of the rail 100. For example, the two end faces of the rail 100 can be divided into a front end face and a rear end face according to the advancing direction of the rail 100, one of the two first detectors 21 can detect the quality of the front end face, and the other of the two first detectors 21 can detect the quality of the rear end face, so that the camera of the first detector 21 can be arranged to face only a single direction. In other embodiments, the end detection mechanism 2 can be provided with only one first detector 21, and the front end face and the rear end face of the rail 100 can be detected by the one first detector 21. At this time, the first detector 21 can be provided with two cameras, and the directions of the two cameras are opposite.

[0073] Referring to Figures 5 to 7, the base 1 is provided with a supporting mechanism 6, the supporting mechanism 6 comprises a first roller 61, the first roller 61 is rotationally connected with the base 1, a circumferential surface of the first roller 61 is used for abutting against a bottom surface of the steel rail 100 to support the steel rail 100, when the steel rail 100 moves along the second direction, the first roller 61 can rotate relative to the base 1 about a central axis of the first roller 61.

[0074] It should be noted that when the steel rail 100 moves along the second direction, the first roller 61 can rotate relative to the base 1 about a central axis of the first roller 61, the central axis of the first roller 61 can be perpendicular to the second direction and parallel to the ground of the base 1, for example, the central axis of the first roller 61 can be parallel to the Y-axis direction shown in the figure.

[0075] The first roller 61 abutting against the bottom surface of the steel rail 100, the base 1 can support the steel rail 100 through the first roller 61, when the steel rail 100 moves relative to the base 1, the friction between the steel rail 100 and the first roller 61 can cause the first roller 61 to rotate relative to the base 1, reducing the friction between the steel rail 100 and the first roller 61, so as to reduce the wear of the surface of the steel rail 100 in the detection process, which helps to ensure the overall quality of the steel rail 100.

[0076] In some embodiments, the supporting mechanism 6 can comprise a plurality of first rollers 61, the plurality of first rollers 61 can be arranged at intervals along the second direction, so that the plurality of first rollers 61 can support different areas of the steel rail 100, shorten the cantilever length of the steel rail 100, which can reduce the bending of the steel rail 100 due to gravity in the detection process, and help to improve the accuracy of the detection result of the steel rail 100; in addition, the steel rail 100 bent due to gravity is prone to up and down shaking in the conveying process, therefore, reducing the bending of the steel rail 100 due to gravity in the detection process can also reduce the shaking of the steel rail 100 in the conveying process, which helps to improve the accuracy of the detection.

[0077] In some embodiments, the base 1 can comprise a first seat body 12, a second seat body 13 and a third seat body 14 arranged at intervals along the second direction in sequence, the first seat body 12, the second seat body 13 and the third seat body 14 are respectively used for being fixed with the ground, wherein the end detection mechanism 2 and the peripheral detection mechanism 3 can be installed on the second seat body 13, and the plurality of first rollers 61 can be respectively installed on the first seat body 12, the second seat body 13 and the third seat body 14, so that the vibration generated when the steel rail 100 moves relative to the first roller 61 can be reduced from being transmitted between the first seat body 12, the second seat body 13 and the third seat body 14, which helps to improve the accuracy of the detection result.

[0078] Referring to Figure 6 and Figure 7The support mechanism 6 further comprises a first mounting member 62 slidingly connected with the base 1, and the first roller 61 is rotatably arranged on the first mounting member 62. The first mounting member 62 is slidable relative to the base 1 in a direction perpendicular to the second direction, so as to increase or decrease the distance between the first roller 61 and the bottom plate 11 of the base 1.

[0079] It should be noted that the sliding direction of the first mounting member 62 can be along the Z-axis direction shown in the figure. When the second mounting member 4 slides along the Z-axis direction shown in the figure, the distance between the first roller 61 and the bottom plate 11 of the base 1 can be increased or decreased.

[0080] The first mounting member 62 is arranged to be slidable relative to the base 1 in a direction perpendicular to the bottom plate 11 of the base 1, and the first roller 61 is rotatably arranged on the first mounting member 62. The movement of the first mounting member 62 can adjust the distance between the first roller 61 and the bottom plate 11. Then, the height of the first roller 61 can be raised or lowered to adapt to the shape of the rail 100, so as to reduce the bending of the rail 100 during the detection.

[0081] In some embodiments, the support mechanism 6 can comprise a first support assembly 601 and a second support assembly 602. The first support assembly 601 and the second support assembly 602 can each comprise a first roller 61. The first support assembly 601 can be provided in two, and the two first support assemblies 601 can be arranged at two ends of the base 1 along the second direction. The second support assembly 602 can be arranged between the two first support assemblies 601 and in a middle region of the base 1. In some embodiments, the second support assembly 602 can comprise a first mounting member 62, and the first mounting member 62 of the second support assembly 602 is slidingly connected with the base 1. The relative distance between the first roller 61 and the bottom plate 11 of the base 1 can be adjusted by adjusting the relative position of the first mounting member 62 of the second support assembly 602 and the base 1, so that the first rollers 61 of the second support assembly 602 and the first rollers 61 of the two first support assemblies 601 can be in the same straight line. In other embodiments, the first support assembly 601 can comprise a first mounting member 62, and the first mounting member 62 of the first support assembly 601 is slidingly connected with the base 1. In this way, the positions of all the first rollers 61 can be adjusted to be in the same straight line. In still other embodiments, the first support assembly 601 and the second support assembly 602 can each comprise a first mounting member 62.
