Description

Technical Field

[0001] This utility model relates to the field of wheel maintenance technology, and in particular to an auxiliary device for wheel maintenance. Background Technology

[0002] Wheels are crucial components of high-speed trains and play a vital role in their maintenance. Wheel flatness inspection is a key aspect of wheel performance testing, employing high-precision equipment to quantitatively assess indicators such as microscopic undulations and radial / axial runout errors on the wheel's working surface. For example, tools like dial indicators can be used to perform multi-point measurements on the wheel, and the flatness is determined by comparing and analyzing the measurement data. However, this method has relatively low efficiency and accuracy. Some wheel inspection methods utilize electronic analysis equipment, but these are complex and require numerous sensors, making their accuracy susceptible to factors such as light sources, external contaminants, wheel surface dirt, and sensor wear. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wheel inspection auxiliary device that uses the lever principle to record the protrusions or depressions on the outer surface of the wheel on recording paper. The wheel and the recording device move synchronously, thereby improving the detection accuracy and efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] This utility model provides a wheel maintenance auxiliary device, including a maintenance track, an adjustment support assembly and a recording device. Two maintenance tracks are arranged side by side, and at least one maintenance track is provided with a drive assembly. Each maintenance track is provided with at least one set of rotation limit assemblies. The drive assembly is used to drive the wheel to rotate on the upper side of the rotation limit assembly.

[0006] The adjustable support assembly is located outside the maintenance track and connected to the recording device. The adjustable support assembly is used to change the height and lateral displacement of the recording device. The recording device includes a lever mechanism, one end of which is connected to a recording pen. The lever mechanism causes the recording pen to form a mark on the surface of the recording paper during the rotation of the wheel.

[0007] As a further implementation, the lever mechanism includes a fixed plate and a balance bar, the balance bar being rotatably connected to the underside of the fixed plate, and the end of the balance bar away from the recording pen being connected to the fixed plate via a spring.

[0008] As a further implementation, one end of the stabilizer bar that mounts the spring has a detection body for contacting the wheel surface.

[0009] As a further implementation, one end of the recording paper is wound on a paper tube, and the other end is wound on a guide roller, which is connected to a rotational power source.

[0010] As a further implementation, the adjusting support assembly includes a fixed support, a vertical adjusting assembly, and a horizontal adjusting assembly, wherein the vertical adjusting assembly is slidably connected to the fixed support, and the horizontal adjusting assembly is slidably connected to the fixed support.

[0011] As a further implementation, the fixed support is provided with a vertical groove, and the vertical adjustment component has a first slider that cooperates with the groove;

[0012] The vertical adjustment component is provided with a guide groove, and the horizontal adjustment component has a second slider that cooperates with the guide groove.

[0013] As a further implementation, the movement of the first slider relative to the slide groove and the movement of the second slider relative to the guide groove are both driven by the corresponding lead screw and nut mechanism.

[0014] As a further implementation, the drive assembly includes a transmission roller connected to a drive source;

[0015] The rotation limiting assembly includes a limiting roller parallel to the drive roller.

[0016] As a further implementation, the two ends of the limiting roller are respectively rotatably connected to the limiting support.

[0017] As a further implementation, a maintenance platform is also included, wherein the maintenance track, adjustment support assembly, drive assembly and rotation limit assembly are all installed on the upper side of the maintenance platform.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) The recording device of this utility model is connected to the adjustment support assembly, which enables the recording device to move laterally during the rotation of the wheel, and the detection range can cover the entire surface of the wheel, avoiding missed detection. The recording device includes a lever mechanism and a recording pen connected to the lever mechanism. Based on the lever principle, it realizes the recording of the protrusions or depressions on the outer surface of the vehicle. The detection principle is simple and avoids the detection results being affected by factors such as sensor wear.

[0020] (2) The lever mechanism of this utility model includes a balance bar and a fixed plate. The balance bar is rotatably connected to the lower side of the fixed plate. The end of the balance bar away from the recording pen is connected to the fixed plate through a spring. At the same time, the end of the balance bar away from the recording pen is provided with a detection body. The detection body can contact the surface of the wheel. When it is in cooperation with the spring, it can make the recording pen move downward when it encounters a surface protrusion and make the recording pen move upward when it encounters a depression, so as to intuitively reflect the flatness of the wheel surface.

[0021] (3) The present invention provides at least one set of driving components, including a transmission roller. The transmission roller rotates and generates friction with the wheel, causing the wheel to rotate. At the same time, it cooperates with the limiting roller of the rotation limiting component to enable the wheel to rotate stably, which facilitates the detection of the vehicle surface.

[0034] Example 1:

[0035] This embodiment provides a wheel inspection auxiliary device for detecting the flatness of the outer surface of wheel 3, such as... Figure 1 As shown, it includes a maintenance track 1, a maintenance platform 2, an adjustment support assembly 4, a drive assembly 5, and a recording device 6. The maintenance track 1 is set on the upper side of the maintenance platform 2. The adjustment support assembly 4 and the recording device 6 are located on the outside of the maintenance track 1. The recording device 6 is connected to one side of the adjustment support assembly 4. The position of the recording device 6 relative to the wheel 3 can be changed by adjusting the support assembly 4.

[0036] Specifically, there are two maintenance tracks 1, with a certain distance between them. In use, wheels 3 are placed on the upper side of the maintenance track 1, and the two wheels 3 are connected by a connecting shaft. The surface condition of the wheels 3 is detected by the recording device 6. In order to make the maintenance track 1 stably mounted on the upper side of the inspection platform 2, a support member 8 can be set at the bottom of the maintenance track 1; the support member 8 can be a column or other structural form.

[0037] In this embodiment, the adjusting support assembly 4 and the recording device 6 are each provided in two sets to match the two maintenance tracks 1. A rotation limiting assembly 7 is also provided on the upper side of the maintenance track 1. In this embodiment, one maintenance track 1 is provided with one set of driving assembly 5 and one set of rotation limiting assembly 7, with a certain distance between the rotation limiting assembly 7 and the driving assembly 5; the other maintenance track 1 is provided with two sets of rotation limiting assemblies 7, which are spaced a certain distance apart along the length of the maintenance track 1. Under the driving action of the driving assembly 5, they cooperate with the rotation limiting assemblies 7 to make the two wheels 3 rotate synchronously. It is understood that in other embodiments, both maintenance tracks 1 may also be provided with one set of driving assembly 5 and one set of rotation limiting assembly 7.

[0038] The adjustment support assembly 4 is located outside the maintenance track 1, enabling adjustment of the recording device 6 in the vertical direction and along the length of the maintenance track 1, such as... Figure 2 As shown, the adjustment support assembly 4 includes a fixed support 41, a vertical adjustment assembly, and a horizontal adjustment assembly. The bottom end of the fixed support 41 is fixedly connected to the inspection platform 2. The shape of the fixed support 41 can be set arbitrarily, for example, a column structure. The fixed support 41 is provided with a sliding groove 48 inside. The sliding groove 48 has a certain height. The vertical adjustment assembly and the sliding groove 48 form a sliding connection.

[0039] In this embodiment, the vertical adjustment assembly includes a first slider 42, a connecting block 44, a rocking screw 43, and a transmission screw 45. The first slider 42 is slidably connected to a groove 48. The rocking screw 43 passes vertically through the first slider 42, and the first slider 42 and the rocking screw 43 form a screw-nut mechanism similar to a lead screw. When the rocking screw 43 rotates, it can move the first slider 42 up and down. The top of the fixed support 41 is provided with a through hole for the rocking screw 43 to pass through. The rotation of the rocking screw 43 can be manual or electric.

[0040] The inner side of the first slider 42 is fixedly connected to the connecting block 44, which is located inside the fixed support 41. The connecting block 44 has a certain length, and its extension direction is perpendicular to the fixed support 41 and the maintenance track 1. Figure 1 In the view shown, wheel 3 is placed behind the adjusting support assembly 4. A guide groove of a certain length (not shown in the figure) is opened on the rear side of the connecting block 44, and the lateral adjusting assembly is slidably connected to the guide groove. The movement of the lateral adjusting assembly is realized by the transmission screw 45 and the first motor 46. The transmission screw 45 passes through the connecting block 44 and is connected to the first motor 46. Bearings can be installed at the ends of the transmission screw 45 and the connecting block 44. One end of the lateral adjusting assembly has a second slider 47, which is slidably engaged with the guide groove. At the same time, the second slider 47 is threadedly connected to the transmission screw 45, forming a screw-nut mechanism, so that the second slider 47 can move relative to the connecting block 44 under the driving action of the first motor 46, thereby changing the lateral position of the recording device 6.

[0041] like Figure 3As shown, the recording device 6 includes a receiving box 611, a recording pen 67, recording paper 610, a paper tube 69, and a guide roller 68. The recording paper 610, paper tube 69, and guide roller 68 are disposed in the receiving box 611, which is fixed to the rear side of the second slider 47. The paper tube 69 and the guide roller 68 are both installed vertically, and their respective roller shafts are rotatably connected to the receiving box 611. One end of the recording paper 610 is wound around the paper tube 69 and has a certain thickness. There is a certain gap between the guide roller 68 and the paper tube 69 in the length direction of the maintenance track 1. One end of the recording paper 610 is wound around the guide roller 68. The top of the guide roller 68 is connected to a rotational power source, namely a second motor 612. The second motor 612 is located outside the receiving box 611. The rotation of the second motor 612 drives the guide roller 68 to rotate, causing the recording paper 610 to change position.

[0042] The recording paper 610 has length markings, scales, and standard lines on its surface. The length markings, scales, and standard lines can be used to record the unevenness of the wheel 3 surface. If the unevenness exceeds the standard line, it indicates an abnormality on the wheel 3 surface. The length markings and scales record the location information of the abnormality on the wheel 3. After the inspection is completed, the abnormality on the wheel 3 surface can be located and positioned more intuitively based on the trajectory recorded by the recording paper 610, which facilitates maintenance.

[0043] A recording pen 67 is positioned on one side of the recording paper 610, corresponding to a position near the paper tube 69. The recording pen 67 is connected to one end of a balance bar 64, the other end of which has a detection body 65 at its bottom. The detection body 65 is a protruding structure that can contact the surface of the wheel 3. A spring 66 is also connected to the end of the balance bar 64 with the detection body 65, and the top of the spring 66 is connected to the bottom end of a fixing plate 61. Figure 3 As shown, the fixing plate 61 has an L-shaped structure. The corner end of the fixing plate 61 is a certain distance away from the spring 66. An opening 62 is provided at the bottom of the corner end, and a connecting rod 63 is installed in the opening 62. Furthermore, the connecting rod 63 passes through or near the middle position of the balance bar 64, making the balance bar 64 a lever structure. When the wheel 3 rotates, it acts on the detection body 65, causing the balance bar 64 to swing relative to the connecting rod 63. At the same time, the recording paper 610 moves, causing the recording pen 67 to form a recording mark on the recording paper 610.

[0044] Among them, the balance bar 64, the connecting rod 63, the fixing plate 61, and the spring 66 constitute a lever mechanism. In this embodiment, the detection body 65 and the spring 66 cooperate to make the recording pen 67 move downward when encountering a surface protrusion and move upward when encountering a depression, thereby intuitively reflecting the surface flatness of the wheel 3.

[0045] The rotation of wheel 3 is powered by drive assembly 5. In this embodiment, as shown... Figure 1As shown, the drive assembly 5 includes a transmission roller 52 and a drive source, wherein the drive source is a third motor 51. The third motor 51 is mounted on the outside of one of the maintenance tracks 1 via a motor mount, and the motor mount is fixed to the inspection table 2. The third motor 51 is connected to the transmission roller 52, and the axial direction of the transmission roller 52 is perpendicular to the length direction of the maintenance track 1. Of course, in other embodiments, the drive source can also be hydraulically driven or pneumatically driven.

[0046] like Figure 4 and Figure 5 As shown, the rotation limiting assembly 7 mainly includes limiting supports 71 and limiting rollers 72. One limiting support 71 is provided on each side of the maintenance track 1, and the limiting supports 71 are fastened to the maintenance track 1 by bolts 73 and nuts 74. The limiting rollers 72 are rotatably connected between the two limiting supports 71, and the limiting rollers 72 are located on the upper side of the maintenance track 1. The axial direction of the limiting rollers 72 is parallel to the drive roller 52. For the driving wheel 3, the rotation of the wheel 3 relative to the limiting rollers 72 is achieved based on the friction between the drive roller 52 and the wheel 3. The other wheel 3 is the driven end, and its bottom is supported by two limiting rollers 72.

[0047] The working principle of this embodiment is as follows:

[0048] The third motor 51 is started, driving the transmission roller 52 to rotate, which in turn drives the wheel 3 to rotate. At the same time, the second motor 612 rotates synchronously with the first motor 46. The first motor 46 drives the transmission screw 45 to rotate, causing the second slider 47 to move in the guide groove behind the connecting block 44, and to detect the surface of the wheel 3 along its thickness direction. Meanwhile, the second motor 612 drives the paper guide roller 68 to rotate, keeping pace with the rotational speed of the wheel 3 so that the scale of the recording paper 610 is synchronized with the relative position of the outer surface of the wheel 3.

[0049] During the rotation of wheel 3, the detection body 65 moves on the outer wall surface of wheel 3. When the lower surface of the detection body 65 passes over the protruding part of the surface of wheel 3, it pushes the detection body 65 to move upward, thereby causing the rear end of the balance bar 64 to move upward and compress the spring 66. At the same time, the recording pen 67 at the front end of the balance bar 64 moves downward and records the displacement vector of the detection body 65 jumping.

[0050] When the lower surface of the detector 65 passes over the recessed area, the detector 65 is rebounded by the spring 66, causing the detector 65 to slide inside the recess, thereby driving the recording pen 67 to move upward and record the displacement vector of the detector 65 jumping. The above movement continues, and the detector 65, spring 66, balance bar 64 and recording pen 67 work in sync to record the trajectory of the wheel 3 body surface.

[0051] In this embodiment, the recording device 6, with the detection body 65 and recording pen 67 fixed at both ends of the balance bar 64, works in conjunction with the rotation of the wheel 3 to record the protrusions or depressions on the outer surface of the wheel 3, enabling a more intuitive analysis of the wear condition of the wheel 3; and by setting the adjustment support component 4, it can adapt to the detection of wheels 3 of different sizes.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
