Description

Technical Field

[0001] This utility model belongs to the field of railway locomotives, and more specifically, it relates to an automated railway locomotive bearing maintenance and lubrication device. Background Technology

[0002] Railway locomotive bearings are key components used in railway locomotives, serving to support rotating shafts, reduce friction, and transmit loads. Currently, to ensure the normal operation of railway locomotive equipment, it is usually necessary to perform dimensional inspections and lubrication on the bearing components. During the inspection process, maintenance personnel need to visually inspect whether there is severe deformation of the outer and inner rings under pressure. If deformation is found, the bearing component is replaced entirely. If no deformation is found, lubricating grease is applied between the outer and inner rings using a brush. Therefore, it is evident that traditional railway locomotive bearing maintenance methods relying on visual inspection are insufficient to accurately determine minor deformations of the outer and inner rings. Furthermore, the brush-applying method cannot accurately control the amount of lubricating grease; insufficient lubrication can lead to rapid wear and fatigue of the bearing components. Utility Model Content

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0021] like Figures 1-7As shown, this utility model provides an automated railway locomotive bearing maintenance and lubrication device, including a base plate 1; a column 5 is welded to the upper side of the base plate 1, a top plate 9 is welded to the top of the column 5, a bracket 4 is welded to the upper side of the base plate 1 near the front end, a support plate 6 is welded to the rear side of the bracket 4, and a control machine 3 is installed on the front side of the bracket 4; it also includes a turntable 7 and a guide rod 16; a clamping block 22 is slidably connected to the upper side of the turntable 7, a bearing component 26 is placed on the upper side of the turntable 7, the support plate 6 is rotatably connected to the outer side of the turntable 7, and a rotary motor 25 is installed on the upper side of the support plate 6. A drive gear 8 is mounted on the motor shaft of the 25, and a push cylinder 23 is meshed with the outer side of the turntable 7; a slide 15 is slidably connected to the outer side of the guide rod 16, and a through hole is provided at the center of the slide 15. An oil injection pipe 17 is bonded to the through hole of the slide 15, an oil delivery pipe 18 is installed at the top of the oil injection pipe 17, and an oil storage cylinder 11 is installed at the other end of the oil delivery pipe 18. A support cylinder 10 is screwed to the outer side of the oil storage cylinder 11, and an electric telescopic push cylinder 2 is installed on the upper side of the support cylinder 10. A piston plate 13 is installed at the bottom of the telescopic rod of the electric telescopic push cylinder 2, and a sealing gasket 12 is bonded to the outer side of the piston plate 13.

[0022] In this embodiment of the present invention, a visual camera 19 is installed on the lower side of the bracket 4, and an annular lighting plate 21 is installed on the lower side of the bracket 4. The annular lighting plate 21 is distributed outside the visual camera 19. The visual camera 19 and the turntable 7 are vertically opposite each other. The visual camera 19 is connected to the image recognition and detection module in the control unit 3 through a wire, and the annular lighting plate 21 is connected to the lighting control module in the control unit 3 through a wire. Under the shadowless illumination of the annular lighting plate 21, the visual camera 19 takes pictures of the bearing component 26 placed on the turntable 7, and transmits the captured image to the image recognition and detection module in the control unit 3 through a wire to perform contour comparison detection of the inner and outer rings of the bearing component 26. This completes the accurate identification of the degree of minor deformation of the inner and outer rings of the bearing component 26, and improves the accuracy of deformation identification of the inner and outer rings of the bearing component 26.

[0023] In this embodiment of the utility model, the outer side of the turntable 7 is provided with an external tooth structure near the bottom end. The drive gear 8 is meshed with the external tooth structure of the turntable 7. During the process of the rotary motor 25 driving the turntable 7 to rotate through the drive gear 8, the turntable 7 drives the bearing component 26 clamped on the upper side to rotate synchronously, completing the spin coating and injection of grease between the inner and outer rings of the bearing component 26. The center of the outer side of the turntable 7 is provided with a thread structure. The upper side of the turntable 7 is provided with six sets of open grooves. The open grooves are arranged in a circular array around the vertical central axis of the turntable 7. The inner wall of the open groove of the turntable 7 is provided with a sliding groove.

[0024] In this embodiment of the present invention, there are six sets of clamping blocks 22. The clamping blocks 22 are arranged in a circular array around the vertical central axis of the turntable 7. Each set of clamping blocks 22 has a sloping structure on its lower side and a rectangular protrusion on its upper side. The left and right sides of the clamping blocks 22 are welded with protruding strips 24. The protruding strips 24 are embedded in the inner side of the sliding groove of the groove wall of the opening of the turntable 7. The sliding groove of the groove wall of the opening of the turntable 7 supports the horizontal directional movement of the clamping blocks 22 through the protruding strips 24, ensuring that the rectangular protrusions of the clamping blocks 22 stably push and clamp the bearing component 26.

[0025] In this embodiment of the utility model, the push cylinder 23 is a cylindrical structure that runs vertically through the body. The inner side of the push cylinder 23 is provided with a threaded structure. The inner side of the push cylinder 23 is threadedly connected to the outer side of the turntable 7. When the push cylinder 23 rotates, it moves up and down along the threaded structure on the outer side of the turntable 7. When the push cylinder 23 moves upward, the top edge of the push cylinder 23 pushes the inclined structure of the six sets of clamping blocks 22 to move synchronously and centripetally along the groove of the inner wall of the groove of the turntable 7. This allows the protrusions on the upper side of the six sets of clamping blocks 22 to clamp and fix the bearing component 26 in the center, ensuring that the bearing component 26 rotates synchronously and stably with the turntable 7, and that the inner and outer rings of the bearing component 26 are evenly and stably filled with oil.

[0026] In this embodiment of the utility model, the slide 15 is provided with a threaded through hole that runs from front to back near the left end, and the slide 15 is provided with a through hole that runs from front to back near the right end. The guide rod 16 is inserted into the through hole structure of the slide 15. A threaded rod 14 is rotatably connected in the threaded through hole of the slide 15. An adjustment knob 20 is welded to the front end of the threaded rod 14. During the process of the adjustment knob 20 driving the threaded rod 14 to rotate, the threaded rod 14 drives the slide 15, which is meshed with the outer side, to move back and forth along the guide rod 16. This allows the oil injection pipe 17, which is bonded in the through hole on the upper side of the slide 15, to adjust the oil injection position according to the diameter of the bearing component 26, thereby adapting to the oil injection work of bearings of different specifications.

[0027] Specific usage and function of this utility model embodiment: In the automated maintenance and lubrication of railway locomotive bearings, this invention first places the bearing component 26 on the upper side of the turntable 7. Then, the pusher cylinder 23 is manually rotated. Since the inner thread of the pusher cylinder 23 is threadedly connected to the outer thread structure of the turntable 7, the top opening of the pusher cylinder 23 pushes against the inclined structure of the six sets of clamping blocks 22, causing them to move concentrically along the grooves of the openings on the turntable 7. This allows the cuboid protrusions on the upper side of the six sets of clamping blocks 22 to centrally position and press the bearing component 26. The control unit 3 controls the lighting panel 21 via wires for shadowless illumination. The control unit 3 also controls the vision camera 19 via wires to capture the overall outline of the upper side of the bearing component 26. The vision camera 19 transmits the captured image back to the image recognition and detection module of the control unit 3 via wires for comparison between the standard and actual outlines of the bearing inner and outer rings. If the actual outline deformation of the bearing component 26 matches the standard outline, the maintenance personnel manually... Rotating the adjustment knob 20 causes the slide 15, which is engaged with the outer side of the threaded rod 14, to move horizontally back and forth along the guide rod 16 until the bottom port of the oil injection pipe 17 is aligned between the inner and outer rings of the bearing component 26. Then, the control machine 3 controls the electric telescopic push cylinder 2 and the rotary motor 25 to start synchronously via the wire. The rotary motor 25 drives the drive gear 8 to rotate. Since the drive gear 8 is engaged with the outer tooth structure of the turntable 7, the drive gear 8 drives the turntable 7, which is engaged with the outer side, to rotate synchronously. The turntable 7 drives the bearing component 26, which is clamped on the upper side, to rotate. The telescopic rod of the electric telescopic push cylinder 2 pushes the sealing gasket 12, which is bonded to the outer side of the piston plate 13, to move downward against the oil reservoir 11. At this time, the grease stored in the oil reservoir 11 is transported to the oil injection pipe 17 along the oil supply pipe 18. The grease is applied from the bottom port of the oil injection pipe 17 to the area between the inner and outer rings of the bearing component 26, thus completing the grease filling work of the railway locomotive bearing.

[0028] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The electric telescopic push cylinder 2, control unit 3, vision camera 19, lighting board 21, and rotary motor 25 mentioned above are all common commercially available components. Upon purchase and use, simply connect them according to the instruction manual provided; therefore, further details are omitted here.
