Description

Technical Field

[0001] The utility model relates to a rail grinding vehicle device, belonging to the technical field of engineering construction devices. Background Art

[0002] Over long-term use, rails develop defects such as fish scales, wave wear, and cracks due to repeated rolling of trains, the effects of the natural environment, and the inherent characteristics of the material. For example, fish scales are a common surface defect on rails. They roughen the rail surface and increase the friction coefficient between the wheel and rail. This not only causes increased vibration and noise during train operation, but can also lead to abnormal wheel-rail contact, increasing the risk of derailment. Furthermore, the friction between the wheels and rails during train operation causes gradual wear of the rail surface. If left untreated, this wear will continue to intensify, shortening the rail's service life.

[0003] Therefore, it is necessary to grind the rails. Grinding can remove the wear layer on the surface of the rails and restore the rails to a shape and size close to their original shape, thereby extending the service life of the rails. Grinding can remove these defects and restore the surface of the rails to a smooth surface, ensuring the stability and safety of train travel.

[0004] In existing technology, rail grinding is typically performed semi-manually, as fully automated equipment is not yet mature. Semi-manual grinding primarily relies on workers using handheld grinding tools or simple-to-operate grinding devices, operating at speeds far lower than mechanized equipment. Manual grinding can take days or even longer to complete on a long stretch of track. This low efficiency can also lead to extended disruptions to rail transportation on sections of track that require urgent maintenance, impacting normal operations.

[0005] Therefore, it is necessary to improve the prior art to overcome the above defects. Utility Model Content

[0033] See also Figures 1 to 2 As shown, a rail grinding vehicle device includes a grinding frame 1, a rail rest assembly 3 disposed on the grinding frame 1, and a grinding assembly 4. The grinding frame 1 is adapted to move over the rail to be ground. The rail rest assemblies 3 are disposed on both sides of the grinding frame 1 and adapted to rest against the outer side surface 21 of the rail to assist in guiding the movement of the grinding frame 1. The grinding assembly 4 can move vertically and horizontally relative to the grinding frame 1 to grind the upper surface of the rail. The coordination of these components enables fully automated rail grinding without manual intervention, with high grinding speed and precision, significantly saving human resources while improving grinding efficiency.

[0034] Specifically, the grinding frame 1 has a mounting frame 11, and the grinding assembly 4 is connected to the mounting frame 11 through a first drive assembly 5. The first drive assembly 5 can drive the grinding assembly 4 to move in a direction perpendicular to the extension direction of the rail, so that the grinding assembly 4 can move horizontally relative to the rail for grinding.

[0035] The first driving component 5 includes a first driving member 51 arranged in the mounting frame 11, a screw rod 52 connected to the first driving member 51, and a driving block 53 sleeved on the screw rod 52. The grinding component 4 is connected to the driving block 53. The first driving member 51 can drive the screw rod 52 to rotate and then drive the driving block 53 to move along the extension direction of the screw rod 52 to realize the horizontal movement grinding function of the grinding component 4.

[0036] In order to further increase the stability of the grinding assembly 4 during horizontal movement, in this embodiment, there are slide rails 54 on the mounting frames 11 on both sides of the screw rod 52, and corresponding slide grooves 55 are provided on the grinding assembly 4. The slide grooves 55 slide with the slide rails 54, so that when the driving block 53 moves, it can move along the slide rails 54, playing an auxiliary guiding role and improving the stability of the entire moving process.

[0037] As described above, the grinding assembly 4 includes a fixed frame 41 connected to the sliding block and a grinding component 42 connected to the fixed frame 41. The grinding component 42 includes a second driving member 43 connected to the fixed frame 41 and a grinding head 44 connected to the driving end of the second driving member 43. The second driving member 43 can drive the grinding head 44 to move toward or away from the rail to control whether the rail is ground or not.

[0038] The grinding assembly 4 also includes a third driving member 45 connecting the fixed frame 41 and the second driving member 43. The third driving member 45 can drive the second driving member 43 to rotate relative to the fixed frame 41, so that when the grinding head 44 is working, it can be driven by the third driving member 45 to achieve a certain angle with the rail, thereby achieving more grinding effect requirements.

[0039] In this embodiment, the first driving member 51 and the third driving member 45 are servo motors, and the second driving member 43 is a pneumatic cylinder, an electric cylinder or a hydraulic cylinder.

[0040] The rail support assembly 3 includes a rail support frame 31 connected to the fixed frame 41 and a guide wheel 32 rotatably set on the rail support frame 31. The guide wheel 32 abuts against the outer side surface 21 of the rail, so that the rail is clamped by the two rail support assemblies 3, which plays an auxiliary guiding role in the movement of the grinding frame 1. Compared with the prior art that abuts against the inner side surface of the rail, the inner side surface may be deformed by the pressure of the wheel when the train is running, and the guiding stability is poor. The outer side surface 21 is usually intact, and the guiding assistance is more stable.

[0041] It is worth noting that, in this embodiment, there are at least four groups of grinding assemblies 4, which are staggered on both sides of the grinding frame 1, and each group of grinding assemblies 4 can independently control the grinding effect to meet complex grinding requirements.

[0042] The grinding frame 1 includes a body 12 and wheels 13 disposed at the bottom of the body 12. At least one set of wheels 13 is connected to a fourth drive assembly 14 and is driven by the fourth drive assembly 14 to rotate, thereby achieving self-movement of the grinding frame 1. In this embodiment, the body 12 is I-shaped to minimize its own weight while ensuring stable operation.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
