Description

Technical Field

[0001] The present invention belongs to the technical field of wheel rim lubrication, and more specifically, relates to a wheel rim lubrication device, a wheel rim lubrication positioning tool and an installation method. Background Art

[0002] High-speed trains experience dry wear between the wheels and rails when running on track, accompanied by friction noise. Even when running in a straight line, the wheel flanges rub against the side of the track, creating running resistance and causing wear on both the wheel flanges and the track. This problem is particularly prominent when running on lines with multiple curves.

[0003] Lubricating the wheel flanges with a wheel flange lubrication device significantly reduces wheel and rail wear, effectively improving friction between the wheels and rails, lowering train running resistance, reducing wheel-rail noise emissions and power loss, thereby slowing wheel-rail wear, extending wheel and rail lifespan, and helping to reduce vehicle operating and maintenance costs. This requires strict control of the relative position of the wheel flange nozzles and the wheelset, ensuring precise lubrication at the corresponding positions of the wheelset flanges. This reduces wheel flange wear, reduces the number of wheelset turning and repairs, and reduces noise generation.

[0004] Existing high-speed trains generally install wheel rim lubrication devices during the detraining process (i.e., the process of preparing the car body and connecting it to the bogie). The wheel rim lubrication devices need to be installed or adjusted in a narrow trench. Since the equipment surrounding the wheel rim lubrication device is generally compactly arranged, conventional tools for adjustment and inspection operations have poor accessibility. The relative dimensions of the wheel rim lubrication device nozzle and the wheelset (wheel rim) are generally measured using a box ruler. This is affected by the external characteristics of the wheel rim and nozzle and their relative three-dimensional dimensions (the box ruler contacts the wheelset rim with a surface-to-arc surface), resulting in large errors and low efficiency in the above measurements. This, in turn, leads to poor positional consistency of the wheel rim lubrication devices throughout the train and uneven wear conditions of the train wheel rims. The nozzle of the wheel rim lubrication device can only be adjusted longitudinally, making it difficult to meet the needs of multi-angle adjustment. Summary of the Invention

[0038] Please also refer to Figures 1 to 10 The wheel rim lubrication device, wheel rim lubrication positioning fixture, and installation method provided by the present invention are now described. The wheel rim lubrication device includes a connecting base 1 connected to the bogie, a mounting frame 2 connected to the connecting base 1, and a fuel injector 3 disposed on the mounting frame 2. The mounting frame 2 is provided with a first long hole 21 extending in the front-to-back direction and a second long hole 22 extending in the up-to-down direction. The connecting base 1 is provided with a third long hole 11 extending in the up-to-down direction and a fourth long hole 12 extending in the front-to-back direction. The mounting frame 2 and the connecting base 1 are connected by a first connecting member 14 provided through the first long hole 21 and the third long hole 11, and a second connecting member 15 provided through the second long hole 22 and the fourth long hole 12. The mounting frame 2 can swing vertically relative to the connecting base 1 to adjust the pitch angle of the fuel injector 3. The mounting frame 2 can also move forward and backward or up and down relative to the connecting base 1 to adjust the position of the fuel injector 3.

[0039] Compared with the prior art, the wheel rim lubrication device provided in this embodiment reliably connects the mounting frame 2 and the connecting seat 1 through the first connecting member 14 arranged in the first long hole 21 and the third long hole 11 and the second connecting member 15 arranged in the second long hole 22 and the fourth long hole 12, and can adjust the front and rear up and down positions and the pitch angle of the fuel injector 3, thereby ensuring the accuracy of the position installation of the fuel injector 3, achieving effective lubrication of the wheel rim 82 and the track, extending the interval time for grinding the wheel rim 82, greatly improving the service life of the wheelset and the track, and reducing the risk of train derailment.

[0040] In this embodiment, wheel 8 has a tread 81 that contacts the top surface of the track and a rim 82 located inside tread 81. It is connected to the bogie via a connecting base 1, and a mounting frame 2 is attached to the side of the connecting base 1 near rim 82, i.e., inside wheel 8. The fuel injector 3 is then connected to the mounting frame 2. This device features a simple structure, low cost, and quick and easy installation. Adjusting the relative position of the connecting base 1 and mounting frame 2 allows for three-dimensional adjustment of the fuel injector 3, ensuring effective alignment between the fuel injector 3 and the rim 82, thus meeting the requirements for rim lubrication.

[0041] Specifically, the wheel rim lubrication device can be installed on the first wheelset or all wheelsets of the locomotive, or on the first wheelset or all wheelsets of all cars, and the installation position can be selected according to needs.

[0042] The first connecting member 14 is inserted through the first and third elongated holes 21 and 11, and the second connecting member 15 is inserted through the second and fourth elongated holes 22 and 12. By adjusting the relative position and angle between the mounting bracket 2 and the connecting base 1, the position and angle of the fuel injector 3 can be adjusted. This includes parameters such as the fore-aft position, the vertical height, and the pitch angle of the fuel injector 3. This allows the fuel injector 3 to accurately align with the wheel rim 82, effectively lubricating the wheel rim 82.

[0043] The first and third slots 21 and 11 are formed by combining a transverse and a longitudinal hole, meeting the dual requirements of front-to-back and up-down position adjustment. The second and fourth slots 22 and 12 are also formed by combining a transverse and a longitudinal hole, also meeting the dual requirements of front-to-back and up-down position adjustment. This combination also allows for adjustment of the pitch angle of the mounting bracket 2, allowing the mounting bracket 2 to swing vertically to adjust the pitch angle of the fuel injector 3, ensuring effective lubrication of the wheel rim 82.

[0044] In one possible implementation, please also refer to Figures 1 to 10 A first oblique long hole 23 is provided on the mounting frame 2, and the first oblique long hole 23 is set at an acute angle to the third long hole 11 and the fourth long hole 12 respectively, and the central axis of the first oblique long hole 23 is located on the symmetry axis of the first long hole 21 and the second long hole 22; a second oblique long hole 13 is provided on the connecting seat 1, and the second oblique long hole 13 is set at an acute angle to the third long hole 11 and the fourth long hole 12 respectively, and the central axis of the second oblique long hole 13 is perpendicular to the symmetry axis of the third long hole 11 and the fourth long hole 12, and a third connecting member 16 for connecting the mounting frame 2 and the connecting seat 1 is provided through the first oblique long hole 23 and the second oblique long hole 13.

[0045] Furthermore, mounting bracket 2 is further provided with a first oblique slot 23, and connecting base 1 is further provided with a second oblique slot 13. A third connecting member 16 is provided through both the first oblique slot 23 and the second oblique slot 13, and can cooperate with the first connecting member 14 and the second connecting member 15 to effectively lock the relative position of connecting base 1 and mounting bracket 2. The provision of the first oblique slot 23 and the second oblique slot 13 facilitates adjustment of the pitch angle of mounting bracket 2, while achieving a three-point connection between connecting base 1 and mounting bracket 2, ensuring connection reliability and improving the positional stability of injector 3.

[0046] In one possible implementation, please also refer to Figures 1 to 10 The mounting frame 2 has a horizontal plate 25 that is horizontally arranged and extends toward one side of the wheel 8. The horizontal plate 25 is provided with a reference hole 26 and an adjustment hole 27 that pass through the horizontal plate 25 from top to bottom. The adjustment hole 27 is an arc-shaped hole and is located on the side of the reference hole 26 close to the wheel 8. The fuel injector 3 is connected to the bottom of the horizontal plate 25 through a plurality of fourth connecting members 24 that respectively pass through the reference hole 26 and the adjustment hole 27.

[0047] In this embodiment, the horizontal plate 25 on the mounting frame 2 is used to mount the fuel injector 3. The reference hole 26 on the horizontal plate 25 serves as a hinge axis. The two adjustment holes 27 are arc-shaped holes extending a predetermined length. Before locking the fourth connecting member 24, the horizontal angle of the fuel injector 3 can be adjusted by horizontally rotating the reference hole 26 about its axis. The horizontal angle adjustment range of the fuel injector 3 is 5° to the left and right. This allows the fuel injector 3 to be adjusted vertically, forward and backward, in pitch, and horizontally, meeting the requirements for position and angle adjustment of the fuel injector 3 and improving the ease of structural installation.

[0048] In some embodiments, please refer to Figures 1 to 10 The fuel injector 3 is connected to a liquid supply pipeline 31, and the mounting frame 2 is also provided with a first mounting plate 28 for limiting the liquid supply pipeline 31. The first mounting plate 28 is located on the side of the mounting frame 2 away from the wheel 8, and the liquid supply pipeline 31 is set through the first mounting plate 28.

[0049] In this embodiment, the liquid delivery pipeline 31 connected to the fuel injector 3 passes through a preset hole on the first mounting plate 28. The preset hole can limit the liquid delivery pipeline 31, so that the liquid delivery pipeline 31 can maintain a stable position state, avoid bending of the liquid delivery pipeline 31 due to pressure changes, and thus avoid affecting the injection direction of the fuel injector 3, thereby improving the accuracy of the injection position.

[0050] In one possible implementation, please also refer to Figures 1 to 10The connecting seat 1 includes an arc-shaped vertical plate 17 arranged around the outer periphery of the wheel 8, a connecting plate 18 connected to the lower part of the upper part of the arc-shaped vertical plate 17, and a second mounting vertical plate 19 connected to the lower part of the arc-shaped vertical plate 17. The connecting plate 18 can be connected to the bogie, and the mounting frame 2 is connected to the top of the second mounting vertical plate 19.

[0051] In this embodiment, curved upright plate 17 is mounted on the bogie using connecting plate 18, facilitating the structural layout of the wheel rim lubrication device and improving installation convenience and reliability. Curved upright plate 17 conforms to the arc of wheel 8, allowing the oil injector 3 to better approach the wheel rim 82, ensuring the required oil injection range.

[0052] Based on the same inventive concept, an embodiment of the present application also provides a wheel rim lubrication positioning tool, including an adsorption component 4, a positioning template 5 and a spirit level 6. The adsorption component 4 includes an upper clamping block 41 clamped above the positioning template 5 and a lower clamping block 42 clamped below the positioning template 5. The upper clamping block 41 and the lower clamping block 42 are respectively connected to the wheel 8. The spirit level 6 is connected to the bottom of the lower clamping block 42 for indicating the horizontal state of the positioning template 5.

[0053] The wheel rim lubrication positioning tool provided in the embodiment of the present application utilizes an upper clamping block 41 and a lower clamping block 42 to cooperate with each other to clamp on the upper and lower sides of the positioning template 5, thereby ensuring the position accuracy of the positioning template 5. The positioning template 5 is used to effectively limit the position of the fuel injector 3, thereby ensuring the accuracy of the position installation of the fuel injector 3 and achieving effective lubrication of the wheel rim 82 and the track. The above-mentioned positioning tool is convenient and quick to install, easy to use, and has good alignment, thereby effectively improving the installation efficiency of the wheel rim lubrication device.

[0054] In this embodiment, the positioning template 5 is attached to the wheel 8 using an adsorption assembly 4, and the horizontal position of the positioning template 5 is monitored using a level 6. The adsorption assembly 4 is formed by combining an upper clamping block 41 and a lower clamping block 42. The upper clamping block 41 and the lower clamping block 42 can be connected by various connection methods such as magnetic attraction, connector connection, and snap connection to achieve reliable fixation of the positioning template 5.

[0055] In one possible implementation, please also refer to Figures 1 to 10 One side edge of the positioning template 5 contacts and mates with the tread 81 and the circumferential wall of the wheel rim 82. A positioning groove 51 is provided on the positioning template 5, extending to the other side edge of the positioning template 5. Positioning groove 51 is used to position the oil injector 3. One side edge of the positioning template 5 is capable of limiting engagement with the outer rim of the wheel 8, specifically contacting the tread 81 and the circumferential wall of the wheel rim 82. This ensures the positioning accuracy of the positioning template 5, ensuring that the relative position of the oil injector 3 and the wheel rim 82 remains consistent after the wheel rim lubrication device is installed, thereby improving lubrication effectiveness.

[0056] In one possible implementation, please also refer to Figures 1 to 10 A first magnetic sheet 43 is provided above the upper clamping block 41, a second magnetic sheet 44 is provided between the upper clamping block 41 and the lower clamping block 42, and a third magnetic sheet 45 is provided below the lower clamping block 42. The first magnetic sheet 43, the second magnetic sheet 44 and the third magnetic sheet 45 can be adsorbed on the side of the wheel 8 respectively.

[0057] In this embodiment, the first, second, and third magnetic sheets 43, 44, and 45 are coupled relative to each other to effectively bring the upper and lower clamping blocks 41 and 42 closer together, facilitating the clamping of the positioning template 5. Simultaneously, the first, second, and third magnetic sheets 43, 44, and 45 are each magnetically attracted to the wheel 8, ensuring the secure installation of the adsorption assembly 4 and, in turn, the secure installation position of the positioning template 5. This effectively limits the position of the fuel injector 3, improves installation efficiency, and ensures installation accuracy. The active connection between these components, achieved through a magnetic attraction structure, allows for flexible assembly and also meets the requirements for the installation and testing of two mirror-image wheels 8 at opposite ends of the same axle, making it suitable for various locations and applications.

[0058] Specifically, the thickness of the second magnetic sheet 44 is greater than that of the first magnetic sheet 43, and the thickness of the second magnetic sheet 44 is greater than that of the third magnetic sheet 45, ensuring effective magnetic attraction with the first magnetic sheet 43 above, and realizing effective clamping of the upper clamping block 41. At the same time, it can also ensure effective magnetic attraction with the third magnetic sheet 45 below, and realize effective clamping of the lower clamping block 42, meeting the clamping and fixing requirements of the positioning template 5.

[0059] In some embodiments, please refer to Figures 1 to 10 The adsorption assembly 4 further includes at least three connecting shafts 7 extending along the circumference of the wheel 8. The connecting shafts 7 are provided through the upper clamping block 41, the positioning template 5, the second magnetic plate 44, and the lower clamping block 42. The connecting shafts 7 are used to limit the relative positions of the upper clamping block 41, the positioning template 5, the second magnetic plate 44, and the lower clamping block 42. The provision of the connecting shafts 7 effectively limits the relative positions of the upper clamping block 41, the lower clamping block 42, and the positioning template 5, preventing relative positional displacement between the components. This provides a good limiting effect, meets the requirement for precise positioning of the oil injector 3, is convenient to use, and improves the installation efficiency of the wheel rim lubrication device.

[0060] Based on the same inventive concept, the embodiment of the present application also provides a wheel rim lubrication installation method, comprising the following steps:

[0061] S100: Installing the wheel rim lubrication and positioning tool onto the wheel 8;

[0062] S200: Pre-install the wheel rim lubrication device on the bogie, and adjust the oil injection nozzle 3 to face the side of the wheel 8;

[0063] S300: Using the wheel rim lubrication positioning fixture to locate the position of the oil nozzle 3, adjusting the relative positions of the connecting base 1 and the mounting frame 2 to drive the oil nozzle 3 to swing vertically or move forward and backward and up and down, so that the oil nozzle 3 is aligned with the positioning template 5 of the wheel rim lubrication positioning fixture in the vertical direction;

[0064] S400: Remove the wheel rim lubrication positioning fixture and complete the installation of the wheel rim lubrication device.

[0065] The rim lubrication installation method provided in the embodiment of the present application first uses the rim lubrication positioning tool to install on the wheel 8, and uses the positioning template 5 to adjust the position and direction of the fuel injector 3, thereby improving the accuracy of the installation position of the fuel injector 3, ensuring the accuracy of the position installation of the fuel injector 3, and realizing effective lubrication of the rim 82 and the track. The above method can conveniently and quickly install the rim lubrication device, effectively improving the installation efficiency of the rim lubrication device.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
