Description

Wheel rim lubrication device, wheel rim lubrication positioning tool and installation method

Technical Field

The 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

When high-speed EMUs are running on tracks, there is dry wear between the wheels and the tracks, accompanied by friction noise. Even when rail vehicles are running in a straight line, the wheel rims will contact and rub against the side of the track, forming running resistance, causing wear of the wheel rims and tracks. This problem is particularly prominent when trains are running on multi-curve lines.

Lubricating the wheel rims by setting up wheel rim lubrication devices can significantly reduce the wear of wheels and tracks, effectively improve the friction performance between wheels and tracks, reduce the running resistance of trains, reduce wheel-rail noise emissions and power loss, and thus slow down the wear of wheels and tracks, increase the life of wheels and tracks, and help reduce vehicle operation and maintenance costs. This requires strict control of the relative position of the wheel rim oil nozzle and the wheelset, and accurate lubrication of the corresponding positions of the wheelset rims, which can reduce the wear of the wheelset rims, reduce the number of wheelset turning and repairs, and reduce noise generation.

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), and the wheel rim lubrication devices need to be installed or adjusted in a narrow trench. Since the surrounding equipment of the wheel rim lubrication device is generally compactly arranged, the accessibility of conventional tools for its adjustment and inspection operations is poor. The relative size of the wheel rim lubrication device nozzle and the wheelset (wheel rim) is generally measured with a box ruler. Affected by the external characteristics of the wheel rim and the nozzle and the relative three-dimensional space size (the box ruler contacts the wheelset rim with a surface in arc contact), the above measurement results in large errors and low efficiency, which in turn leads to poor position 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, which is difficult to meet the needs of multi-angle adjustment.

Summary of the invention

The object of the present invention is to provide a wheel rim lubrication device, a wheel rim lubrication positioning tool and an installation method, which can accurately lubricate specific parts of the wheel rim and improve the convenience of installation.

In this embodiment, the wheel 8 has a tread 81 in contact with the top surface of the track and a rim 82 located inside the tread 81. 82 is connected to the bogie using a connecting seat 1, and a mounting frame 2 is connected to a side of the connecting seat 1 close to the rim 82, that is, the inside position of the wheel 8. Then the oil nozzle 3 is connected to the mounting frame 2. The above device has a simple structure, low cost, and convenient and quick installation. The three-dimensional space adjustment of the oil nozzle 3 is achieved by adjusting the relative position of the connecting seat 1 and the mounting frame 2, which ensures that the oil nozzle 3 is effectively aligned with the rim 82 and meets the requirements of rim lubrication.

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.

The first connecting member 14 is passed through the first long hole 21 and the third long hole 11, and the second connecting member 15 is passed through the second long hole 22 and the fourth long hole 12, and the relative position and relative angle between the mounting frame 2 and the connecting seat 1 are adjusted to adjust the position and angle of the fuel injector 3. The parameters include the front and rear position, the up and down height, and the pitch angle of the fuel injector 3, so that the fuel injector 3 can accurately correspond to the position of the wheel rim 82, and achieve effective lubrication of the position of the wheel rim 82.

The first long hole 21 and the third long hole 11 are in the form of a combination of a transverse hole and a longitudinal hole, which meet the dual requirements of position adjustment in the front-to-back direction and the up-down direction. The second long hole 22 and the fourth long hole 12 are also in the form of a combination of a transverse hole and a longitudinal hole, which also meet the dual requirements of position adjustment in the front-to-back direction and the up-down direction. At this time, the above combination can also achieve the adjustment of the pitch angle of the mounting frame 2, which can make the mounting frame 2 swing vertically to adjust the pitch angle of the injector 3, ensuring effective lubrication of the wheel rim 82.

In a possible implementation, please refer to Figures 1 to 10 together. 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 with 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 with 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 penetrated by the first oblique long hole 23 and the second oblique long hole 13.

On this basis, the mounting frame 2 is further provided with a first oblique long hole 23, and the connecting seat 1 is further provided with a second oblique long hole 13. The third connecting member 16 is provided through the first oblique long hole 23 and the second oblique long hole 13, and can cooperate with the first connecting member 14 and the second connecting member 15 to effectively lock the relative position of the connecting seat 1 and the mounting frame 2. The provision of the first oblique long hole 23 and the second oblique long hole 13 facilitates the adjustment of the pitch angle of the mounting frame 2, and at the same time realizes the three-point connection of the connecting seat 1 and the mounting frame 2, thereby ensuring the reliability of the connection and improving the position stability of the fuel injector 3.

In a possible implementation, please refer to Figures 1 to 10 together. The mounting frame 2 has a horizontal plate 25 that is horizontally arranged and extends to 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 upper and lower parts. 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 correspond to and penetrate the reference hole 26 and the adjustment hole 27.

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 can be used as a hinge axis. The two adjustment holes 27 are arc-shaped holes extending a certain arc length. Before locking the fourth connecting member 24, the horizontal angle of the fuel injector 3 can be adjusted by horizontally rotating around the axis of the reference hole 26. The horizontal angle adjustment range of the fuel injector 3 is 5° left and right. At this point, the fuel injector 3 can be adjusted up and down, front and back, pitch angle and horizontal angle, which meets the position and angle adjustment requirements of the fuel injector 3 and improves the convenience of structural installation.

In some embodiments, please refer to Figures 1 to 10 together.

In the present embodiment, the liquid delivery pipeline 31 connected to the fuel injector 3 passes through a preset hole on the mounting plate 19. The preset hole can limit the liquid delivery pipeline 31 so that the liquid delivery pipeline 31 can maintain a stable position and avoid bending of the liquid delivery pipeline 31 due to pressure changes, thereby avoiding affecting the injection direction of the fuel injector 3 and improving the accuracy of the injection position.

In a possible implementation, please refer to Figures 1 to 10 together.

In this embodiment, the arc-shaped vertical plate 17 is installed on the bogie by using the connecting plate 18, which facilitates the structural layout of the wheel rim lubrication device and improves the convenience and reliability of installation. The arc-shaped vertical plate 17 is adapted to the arc of the wheel 8, so that the oil injection nozzle 3 can be closer to the position of the wheel rim 82, ensuring that the oil injection range meets the requirements.

Based on the same inventive concept, the 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 to indicate the horizontal state of the positioning template 5.

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 sample, and effectively limiting the position of the fuel injector 3 with the help of the positioning template 5, thereby ensuring the accuracy of the installation of the position of the fuel injector 3, thereby 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.

In this embodiment, the positioning template 5 is adsorbed on the wheel 8 by the adsorption component 4, and the horizontal position of the positioning template 5 is monitored by the level 6. The adsorption component 4 is in the form of a combination of an upper clamping block 41 and a lower clamping block 42, and the two can be connected in different ways such as magnetic attraction, connection with a connector, and clamping, which can all achieve reliable fixation of the positioning template 5.

In a possible implementation, please refer to Figures 1 to 10 together, one side edge of the positioning template 5 contacts and cooperates with the tread 81 and the peripheral wall of the wheel rim 82, and a positioning groove 51 extending to the other side edge of the positioning template 5 is provided on the positioning template 5, and the positioning groove 51 is used to position the oil injection nozzle 3. One side edge of the positioning template 5 can be limitedly matched with the outer ring of the wheel 8, that is, it contacts the peripheral wall of the tread 81 and the wheel rim 82, which ensures the positioning accuracy of the positioning template 5, so that the relative position of the oil injection nozzle 3 and the wheel rim 82 remains consistent after the wheel rim lubrication device is installed, thereby improving the lubrication effect.

In a possible implementation, please refer to Figures 1 to 10 together. 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.

In this embodiment, the first magnetic sheet 43, the second magnetic sheet 44, and the third magnetic sheet 45 are used to combine with each other to achieve effective closeness between the upper clamping block 41 and the lower clamping block 42, so as to facilitate the clamping of the positioning template 5. At the same time, the first magnetic sheet 43, the second magnetic sheet 44, and the third magnetic sheet 45 can be magnetically attracted to the wheel 8 to ensure the reliable installation of the adsorption component 4, thereby ensuring the reliable installation position of the positioning template 5, achieving effective position limiting of the installation of the fuel injector 3, improving the installation efficiency, and ensuring the installation accuracy. The above-mentioned components are connected actively by a magnetic attraction structure, which can meet the needs of flexible assembly, and can also meet the installation and detection requirements of the two mirror wheels 8 at both ends of the same axle, and are suitable for different positions and occasions.

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, thereby 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, thereby meeting the clamping and fixing requirements of the positioning template 5.

In some embodiments, please refer to Figures 1 to 10 together. The adsorption assembly 4 also includes at least three connecting shafts 7 extending along the circumference of the wheel 8. The connecting shafts 7 penetrate the upper clamping block 41, the positioning template 5, the second magnetic sheet 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 sheet 44 and the lower clamping block 42. By setting the connecting shafts 7, the relative positions of the upper clamping block 41, the lower clamping block 42 and the positioning template 5 can be effectively limited to avoid relative displacement between the components, have a good limiting effect, meet the precise positioning requirements of the fuel injector 3, have good convenience of use, and improve the installation efficiency of the wheel rim lubrication device.
