Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail detection, in particular to a double-rail corrugation measuring device. Background Art
[0002] In existing technology, a visual rail corrugation measurement trolley primarily consists of a detection unit, a control unit, and a push rod. The detection units are located at both ends of the control unit. Each unit contains running rollers, four probes, and a small camera, enabling stable movement along the rails, measuring corrugation, and capturing relevant images. The control unit, which includes key components such as a controller, battery, and storage device, is responsible for data processing, storage, and transmission. The push rod is connected to the control unit to facilitate operator movement of the trolley.
[0003] The Visual Rail Corrugation Measurement Cart combines measurement and imaging capabilities to accurately measure and visualize rail corrugation. This design not only improves measurement accuracy and efficiency, but also provides strong support for railway track maintenance and inspection.
[0004] However, the existing visual rail corrugation measurement trolley still has many shortcomings, mainly reflected in the following points:
[0005] Limitations in measurement accuracy and range: Existing non-contact dual-track measurement technologies suffer from the disadvantage that their accuracy is easily affected by environmental factors and the surface characteristics of the object being measured, which impacts measurement accuracy and reliability. Certain non-contact measurement technologies may be limited by their measurement distance or angle, making them ineffective in certain scenarios. This limits the technology's scope of application.
[0006] (2) High equipment cost: High-precision non-contact measurement equipment is often expensive, which may increase the overall measurement cost and make it impossible for some projects with limited budgets to adopt these technologies.
[0007] (3) High technical requirements for operators: Non-contact measurement technology usually requires operators to have certain technical knowledge and experience to ensure the correct setting and use of the equipment. This places high demands on the professional quality of the operator.
[0008] (4) Stability issues: In some cases, the stability of non-contact measurement equipment may be affected. For example, slight vibrations of the equipment or air flow disturbances in the environment may cause fluctuations in the measurement results.
[0009] (5) Difficulty in calibration and maintenance: To maintain measurement accuracy, non-contact measurement equipment needs to be calibrated and maintained regularly. However, these processes can be relatively complex and require specialized equipment and personnel to complete.
[0010] In summary, although the non-contact measurement method of the existing dual-track measurement technology has the advantage of not needing to contact the object being measured, it also faces challenges such as susceptibility to interference in accuracy, limited measurement range, high equipment cost, high operating technology requirements, stability issues, and difficulty in calibration and maintenance.

[0039] The utility model provides a double-track corrugation measuring device, such as Figure 1As shown, it includes a measuring component, an extension component 1000, a hand-held part 100 and a connecting rod 700; the measuring component and the extension component 1000 are respectively arranged at both ends of the connecting rod 700, and the hand-held part 100 is connected to the connecting rod 700 for holding the measuring component to measure the rail; the measuring component includes a measuring housing 200, an acceleration sensor 500 and a counting device; the measuring housing 200 is arranged at the end of the connecting rod 700; a detection hole is provided on the housing 200, and the acceleration sensor 500 is arranged in the measuring housing 200 and is arranged corresponding to the detection hole for detecting the acceleration change of the dual-rail corrugation measuring device; the counting device is connected to the measuring component for measuring the moving distance and speed of the dual-rail corrugation measuring device.
[0040] In this embodiment, the measuring assembly is the pipe diameter portion of the overall device, which is disposed at the end of the connecting rod 700 and is used to directly contact and measure the corrugation condition of the rail.
[0041] In this embodiment, a control component may be provided on the connecting rod 700 , and the control component is connected to the measuring component by signal, specifically, by wired connection or by wireless connection such as Bluetooth, WiFi, etc.
[0042] Specifically, in this embodiment, the control component may also be provided on the handheld portion 100 to facilitate manipulation of the measurement component.
[0043] In this embodiment, the measuring assembly includes a housing 200, an acceleration sensor 500 and a counting device, wherein the acceleration sensor 500 and the counting device cooperate to achieve accurate measurement of the corrugation data of the rail.
[0044] Specifically, in this embodiment, when measuring the corrugation data of the rail, the inertial reference method is used for measurement.
[0045] More specifically, during the measurement process, the acceleration sensor 500 will sense the vibration of the rail and transmit the data to the processing unit (computer) for analysis and processing. By calculating the acceleration change of the detection wheel, the corrugation of the rail can be directly reflected.
[0046] In an optional embodiment, a walking component 300 is provided on the measuring component to enable the measuring component to walk on the track.
[0047] Specifically, in this embodiment, the walking assembly 300 can drive the measuring assembly to walk on the rails, thereby achieving the effect of mobile measurement.
[0048] In an optional embodiment, the traveling assembly 300 includes a connecting frame and traveling wheels; the traveling wheels are mounted on the housing 200 via the connecting frame and are used for traveling on the upper surface of the rail.
[0049] Specifically, in this embodiment, the connecting frame is arranged on the outer wall of the shell 200 and is arranged below the shell 200. The running wheels are universal wheels, which can facilitate smooth running on the upper surface of the rail.
[0050] In an optional embodiment, the counting device is a rotary counter 600 for recording the walking distance of the walking component.
[0051] In this embodiment, the number of rotations of the running wheel is counted by the wheel counter 600, so that the travel distance of the running wheel can be obtained according to the circumference of the running wheel and the number of rotations, and the travel acceleration can be obtained by combining the time.
[0052] In this embodiment, the wheel counter 600 is an encoder.
[0053] In an optional embodiment, the traveling assembly 300 further includes a wheel assembly 900 , which is disposed on the housing 200 and below the housing 200 for rolling on the side surface of the rail.
[0054] In this embodiment, the walking assembly 300 also includes a wheel assembly 900, which is connected to the outer shell 200 and is arranged below the outer shell 200. When in use, it is located on the inner side of the rail. The outer diameter of the wheel can abut against the inner wall of the rail, so that it can walk on the inner wall of the rail, which can maintain the stability of the rail corrugation measuring device during driving.
[0055] The arrangement of the wheel assembly 900 can reduce the friction between the measuring device and the rail, and achieve accurate positioning of the measuring device on the rail, thereby ensuring the accuracy of the measuring position and the accuracy of the measuring structure.
[0056] In an optional embodiment, a device slot 800 is provided on the connecting rod 700 for placing items.
[0057] Specifically, in this embodiment, the device slot 800 can be used to place a mobile device, such as a mobile phone, a tablet computer, or a laptop computer, so that after connecting to the control component, the detected data or images can be viewed in real time.
[0058] Specifically, the device slot 800 can be an open disc-shaped structure, that is, it does not have any fixed structure, and the mobile device can be placed directly on the tray. It can also be provided with a fixed structure for fixing the mobile device to prevent the mobile device from detaching from the device slot 800 during driving.
[0059] More specifically, in this embodiment, the fixing structure can be set by snapping or binding with a strap. That is to say, as long as the mobile device can be fixed in the device slot 800 to prevent it from falling off during the driving of the device, it will be fine.
[0060] In an optional embodiment, the measuring component further includes a shock absorbing device, which is connected to the acceleration sensor 500 .
[0061] By setting up the shock absorbing device, the influence of the vibration of the measuring component on the measurement result can be avoided, thereby improving the accuracy and precision of the detection.
[0062] In an optional embodiment, the shock absorbing device includes a shock absorbing rod 400 , one end of the shock absorbing rod 400 is connected to the housing 200 , and the other end of the shock absorbing rod 400 is connected to the acceleration sensor 500 .
[0063] In this embodiment, one end of the shock-absorbing rod 400 is connected to the inner wall of the outer shell 200, and the acceleration sensor 500 is arranged at the other end of the shock-absorbing rod 400. The shock-absorbing rod 400 has a certain elasticity, thereby avoiding hard contact between the acceleration sensor 500 and the rail, that is, avoiding the reduction in detection accuracy caused by vibration, and avoiding the acceleration sensor 500 from colliding with the rail and causing damage, affecting normal measurement.
[0064] It should be pointed out that in this embodiment, the shock absorbing device is a shock absorbing rod 400, but it is not limited to the shock absorbing rod 400. It can also be other shock absorbing structures, such as a shock absorbing spring, etc., as long as it can achieve the shock absorbing effect of the acceleration sensor 500.
[0065] In an optional embodiment, the extension component 1000 is a measurement component.
[0066] In this embodiment, there are two groups of measuring components, which are respectively provided at both ends of the connecting rod 700, that is, one end of the connecting rod 700 is a measuring component, and the extension component 1000 at the other end is also a measuring component.
[0067] It should be pointed out that, in this embodiment, the extension component 1000 can be a measuring component, but it is not limited to a measuring component. It can also be other extension components 1000, such as an internal flaw detector, etc., which is used to detect flaws inside the rail, so that when the rail is broken but not displayed on the outer surface, it can be handled in time, thereby providing safety during use.
[0068] In an optional embodiment, the handheld portion 100 includes two holding rods, one end of the two holding rods are connected to each other, and the other ends are respectively connected to the two ends of the connecting rod 700.
[0069] In this embodiment, the two holding rods are arranged in a herringbone shape, with the connecting end being used for handholding and the other two ends being respectively connected to the two ends of the connecting rod 700, which can ensure the stability and measurement accuracy of the measuring device during measurement.
[0070] It is understandable that there are many ways to set the hand-held portion, as long as it is convenient to hold the connecting rod 700.
[0071] The beneficial effects of the embodiments of the present utility model are:
[0072] By having the acceleration sensor 500 directly contact the rail, interference during measurement is reduced, the measurement range and accuracy are improved, the stability of the device is increased, and the maintenance of the equipment is facilitated.
[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
