Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a grinding device for a core rail and wing rail with an angled feed. Background Technology

[0002] Rails are a major functional component of railway transportation systems, providing guidance and load transfer for running trains. During train operation, railway rails are subjected to alternating loads from multiple directions. With prolonged use, rails suffer increasingly severe damage such as corrugated wear and contact fatigue, affecting the safety and economy of railway transportation. Therefore, rail maintenance and repair have become increasingly important, leading to the development of rail grinding machines. These machines are equipped with grinding devices to polish the rails.

[0003] In the existing technology, the grinding mechanism performs preventive and restorative maintenance work by repeatedly grinding the rail surface. However, the grinding angle of the existing grinding machine is limited, making it difficult to accurately control the grinding of the core rail and wing rail, and thus failing to meet the grinding requirements of the core rail and wing rail. Utility Model Content

[0009] The polishing assembly includes: a polishing motor, a polishing wheel connected to the output end of the polishing motor, and a polishing belt sleeved on the polishing wheel and arranged along a third direction, wherein the planes containing the first direction, the second direction, and the third direction are perpendicular to each other.

[0010] In one embodiment of the present invention, the first driving component includes: an optical shaft passing through the slide table, a first lead screw nut seat disposed on the slide table, and a first driving lead screw threaded through the first lead screw nut seat.

The first frame is fixedly connected to the slide table.

[0011] In one embodiment of the present invention, the feeding mechanism further includes a fixing handle for locking the first frame and the arc plate. The fixing handle passes through the first frame and the arc groove and extends to one side of the arc plate. The first shaft is the shaft of the fixing handle.

[0012] In one embodiment of the present invention, the first frame is provided with a guide rail along the second direction, and the second frame is provided with a slider adapted to the first frame.

[0013] In one embodiment of the present invention, the polishing assembly further includes a third frame, which is disposed on one side of the second frame, and polishing wheels are rotatably connected to both ends of the third frame along a third direction.

[0014] In one embodiment of this utility model, the output end of the grinding motor is connected to the grinding wheel via a belt, the belt is provided with internal teeth, and the output shaft of the grinding motor and the shaft of the grinding wheel are respectively provided with drive teeth that mesh with the internal teeth.

[0015] In one embodiment of the present invention, the second frame is provided with a second lead screw nut seat, and the second frame is provided with a second drive lead screw along a second direction, the second drive lead screw being threaded through the second lead screw nut seat.

[0017] In one embodiment of this utility model, the guide rail and the slider are respectively disposed on both sides of the first frame and the second frame.

[0018] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0019] The present invention discloses a rail wing rail swing angle feeding grinding device. A first frame is connected to a slide table and can move along a first direction (left-right direction) as the slide table moves. The output end of a first drive component is connected to the first frame, driving the first frame and the slide table to move along the first direction. An arc plate is movably connected to the first frame, and a first shaft is movably connected to an arc groove, allowing the feeding component and grinding component to swing at a certain angle relative to the first frame. A second frame of the feeding mechanism is mounted on a swing angle mechanism. The grinding component is movably connected to the second frame along a second direction (up-down direction).

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Example

[0029] Reference Figures 1-5 As shown, the present invention provides a grinding device for the swing angle feed of a core rail and a wing rail, comprising:

[0030] The drive mechanism includes: a slide 1 arranged along a first direction, a first frame 9 connected to the slide 1, and a first drive member 6 whose output end is connected to the slide 1;

[0031] An angle-swinging mechanism includes: an arc-shaped plate 7 movably connected to the first frame 9, an arc-shaped groove 8 formed in the arc-shaped plate 7, and a first shaft 10 disposed in the first frame 9 and movably passing through the arc-shaped groove 8.

[0032] The feeding mechanism includes: a second frame 15 disposed on the swing angle mechanism, a grinding assembly movably connected to the second frame 15 along a second direction, and a second drive member 24 whose output end is connected to the grinding assembly.

[0033] The polishing assembly includes: a polishing motor 13, a polishing wheel 16 connected to the output end of the polishing motor 13, and a polishing belt 11 sleeved on the polishing wheel 16 and arranged along a third direction, wherein the planes containing the first direction, the second direction, and the third direction are perpendicular to each other.

[0034] The present invention discloses a grinding device for a wing rail with a swing angle feed. A first frame 9 is connected to a slide table 1 and can move along a first direction (left-right direction) as the slide table 1 moves. The output end of a first drive component 6 is connected to the first frame 9, driving the first frame 9 and the slide table 1 to move along the first direction. An arc-shaped plate 7 is movably connected to the first frame 9, and a first shaft 10 is movably connected to an arc-shaped groove 8, allowing the feeding component and the grinding component to swing at a certain angle relative to the first frame 9. A second frame 15 of the feeding mechanism is mounted on the swing angle mechanism. The grinding assembly is movably connected to the second frame 15 along the second direction (vertical direction). The grinding motor 13 in the grinding assembly drives the grinding wheel 16 and the grinding belt 11 to grind the weld of the rail. The driving mechanism and the feeding mechanism drive the sand belt 11 to approach and move along the rail direction. The tilting mechanism makes the angle of the sand belt 11 match the weld. Since the planes of the first direction, the second direction and the third direction (front and back direction) are perpendicular to each other, the movement in the space of the three directions is coordinated, and the tilting mechanism is used to grind the weld at different angles.

[0035] Railway tracks are generally equipped with a number of turnouts, including frogs: these are devices that allow wheels to cross from one rail to another. They are located at the intersection of the side rails and the main rails of the turnout. The frog and guard rails consist of the frog center rail, wing rails, and connecting parts. The wing rails are made by bending and planing ordinary steel rails and are connected to the frog center with spacers and bolts to maintain the correct position between them and form the necessary flange grooves so that the wheel flanges can pass smoothly.

[0036] Reference Figure 2 As shown, the first driving component 6 includes: an optical shaft 2 passing through the slide table 1, a first lead screw nut seat 4 disposed on the slide table 1, and a first drive screw 3 threaded through the first lead screw nut seat 4. The optical shaft 2 and the first drive screw 3 are arranged along a first direction. The output end of the first driving component 6 is connected to the drive screw. The first frame 9 is fixedly connected to the slide table 1. The optical shaft 2 passes through the slide table 1, serving as a guide and stabilizer to ensure that the slide table 1 maintains linear motion during movement. In some embodiments, the slide table 1 is also provided with a guide sleeve, through which the optical shaft 2 passes to prevent the slide table 1 from shifting or shaking. The first lead screw nut seat 4 is disposed on the slide table 1 and cooperates with the first drive screw 3 threaded therethrough. When the first driving component 6 works, its output end drives the first drive screw 3 to rotate. Since the first lead screw nut seat 4 is fixed on the slide table 1, the rotational motion of the lead screw is converted into linear motion of the slide table 1 along the first direction defined by the optical shaft 2 and the first drive screw 3. Thus, the slide 1 drives the first frame 9, which is movably connected to it, to move together along the first direction, thereby realizing the movement of the grinding component and the feed component along the first direction.

[0037] Reference Figures 3-4 As shown, the feeding mechanism also includes a fixed handle 14 for locking the first frame 9 and the arc plate 7. The fixed handle 14 passes through the first frame 9 and the arc groove 8 and extends to one side of the arc plate 7. The first shaft 10 is the shaft of the fixed handle 14. The fixed handle 14 is set to lock the first frame 9 and the arc plate 7 at a fixed angle. Lifting the handle disengages the engagement between the handle and the saw teeth and releases the lock. The handle in the free state can be rotated to any position. If the handle is pulled open, the handle will engage with the saw teeth through the action of the spring and lock again.

[0038] Reference Figure 4As shown, the first frame 9 is provided with a guide rail 19 along the second direction, and the second frame 15 is provided with a slider 18 adapted to the first frame 9. When the second driving member 24 drives the second frame 15 to move, the slider 18 on the second frame 15 slides along the guide rail 19 of the first frame 9, effectively reducing friction and resistance during movement and providing limiting and guiding accuracy. In this embodiment, the guide rail 19 and the slider 18 are adapted limiting guide rail 19 and slider 18. The guide rail 19 and the slider 18 are respectively provided on both sides of the second frame 15 along the first direction. A second shaft 12 is also provided between the second frame 15 and the first frame 9. The second shaft 12 is located below the first frame 9 and the second frame 15, so that the second frame 15 is rotatably connected to the first frame 9 through the second shaft 12 as the fulcrum. The radius of the circle where the arc groove 8 is located is the same as the distance from the second shaft 12 to the arc groove 8, so as to realize the rotatable connection.

[0039] Refer to Figure 5 As shown, the grinding assembly also includes a third frame for mounting and supporting the grinding assembly. The third frame is located on one side of the second frame 15. Grinding wheels 16 are rotatably connected to both ends of the third frame along the third direction. During the grinding process, the entire feed assembly and the tilting mechanism are positioned between the two rails to be ground. Grinding is performed by the third frame close to one of the rails, making the space allocation of the device more reasonable and avoiding interference from other mechanisms with the grinding assembly. When grinding the other rail, the direction of the first frame 9 is switched by the 180-degree turning shaft 5, and the grinding assembly, tilting mechanism and feed mechanism are reversed by 180 degrees as a whole. The 180-degree turning shaft 5 is set on the slide table 1 and connected to the first frame 9.

[0040] Reference Figures 2-3 As shown, the upper end of the swing angle and feed assembly is provided with a 180-degree turning shaft. The center of the reciprocating slide 1 is provided with a shaft hole, and the 180-degree turning shaft is provided in the shaft hole. The shaft hole has a certain surface roughness and tolerance, so that the 180-degree turning shaft can rotate in the shaft hole, further driving the swing angle feed assembly to rotate. The 180-degree turning shaft is provided with pin holes on both sides, and the reciprocating slide 1 is provided with an indexing pin on one side. The indexing pin can be inserted into the pin hole of the 180-degree turning shaft to fix the swing angle feed assembly, thereby realizing the 180-degree turning and fixing operation of the swing angle feed assembly.

[0041] Reference Figures 4-5 As shown, the output end of the grinding motor 13 is connected to the grinding wheel 16 via a belt 17. The belt 17 is provided with internal teeth. The output shaft of the grinding motor 13 and the shaft of the grinding wheel 16 are respectively provided with drive teeth 21 that mesh with the internal teeth to prevent slippage and improve the driving force of the sanding belt 11.

[0042] The second frame 15 is provided with a second lead screw nut seat 23, and the second frame 15 is provided with a second drive lead screw 22 along the second direction. The second drive lead screw 22 is threaded through the second lead screw nut seat 23. The second frame 15 is driven to rise and fall by the lead screw, thereby driving the grinding component to move up and down. It has high adjustment accuracy. In the direction of gravity, the lead screw structure can provide self-locking or lifting resistance to maintain the stability of the grinding component.

[0043] The second frame 15 is rotatably connected to the first frame 9 via the second shaft 12. The arc groove 8 is a circular arc groove, and the center of the circular arc groove is located at the axis of the second shaft 12. The first frame 9 gradually narrows in size along the second direction downwards, optimizing the structure of the first frame, ensuring structural strength while reducing the structural documents and materials used, and avoiding interference with the rotation of the second frame. The guide rail 19 and the slider 18 are respectively set on both sides of the first frame 9 and the second frame 15, so that the forces on both sides of the second frame are balanced, increasing the strength and vibration resistance, and reducing the impact of vibration on accuracy.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
