Description

Technical Field

[0001] The invention relates to a track enhancement processing device, and in particular to a track oil film removal system and an oil film removal method. Background Art

[0002] The patent document of the vehicle-type track reinforcement processing equipment applied by our company is CN22148000U. An important application scenario of the track reinforcement vehicle is to process the high rail at the small radius turn of the track. When the rail vehicle passes through the small radius turn at high speed, the high rail needs to withstand the huge centrifugal force of the vehicle, so the loss of this part of the track is particularly serious, and it is the area that the track reinforcement vehicle focuses on strengthening.

[0003] In order to protect the track, an oiler is usually installed before the track enters the small radius area. The lubricating oil produced by the oiler will stick to the wheels of the railcar and be brought to the rails at the small radius bend. Therefore, an oil film is often formed at the junction of the high rail wheel and rail at the small radius bend. Moreover, the longer the track is used, the thicker and stronger this oil film is. As described in the prior art Figure 1 As shown, the oil film generally appears at the track gauge angle, which happens to be the key area for track strengthening.

[0004] However, the presence of the oil film will absorb the energy of the laser, thereby weakening the effect of track strengthening. Therefore, before the strengthening operation, this layer of oil film must be removed. The present invention relates to an adaptive track oil removal device for a track strengthening vehicle suitable for this scenario. Summary of the invention

[0051] The preferred embodiments of the present method will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present method.

[0052] like Figure 1As shown, a track oil film removal system 100, the core components of which include a track vehicle 101 and an enhancement treatment device 104 loaded thereon. The enhancement treatment device 104 is composed of a heating device, a spraying device and a laser device, which are installed on the track vehicle 101 in sequence from front to back to form a complete track enhancement operation unit. The heating device is used to preheat the track surface, the spraying device is responsible for spraying a protective coating or lubricant on the track surface, and the laser device is a key part of the enhancement operation, which hardens the track surface through high-energy laser, thereby improving the wear resistance and service life of the track.

[0053] In order to ensure the effectiveness of the track strengthening operation, the technical solution of the present invention specially designs a track oil removal device 102, which is installed on the rail vehicle 101 through a flexible connection mechanism 103 and is located in front of the heating device. The main function of the track oil removal device 102 is to efficiently remove the oil film on the track surface before the track strengthening operation begins. The design of the flexible connection mechanism 103 enables the track oil removal device 102 to be flexibly adjusted according to the shape and working conditions of the track, ensuring that it always maintains the best contact state with the track surface, thereby achieving efficient and thorough oil film removal. This layout and design not only improves the overall efficiency of the track strengthening operation, but also ensures the stability and reliability of the track strengthening effect by optimizing the pre-process.

[0054] Specifically, Figure 4 As shown, the flexible connection mechanism 103 includes a first connection plate 10, a connection rod 30 and a second connection plate 20. The first connection plate 10 is firmly mounted on the rail vehicle 101, while the second connection plate 20 is tightly connected to the rail degreasing device 102. The connection rod 30 serves as an intermediate connection member, and its two ends are respectively connected to the first connection plate 10 and the second connection plate 20 by a rotation connection. This technical means gives the rail degreasing device 102 the ability to flexibly adjust in space, so that it can automatically adapt to the curve and unevenness of the track according to the shape and working conditions of the track, thereby ensuring that the degreasing device always maintains the best contact state with the track surface. Through the support and adjustment function of the flexible connection mechanism 103, the rail degreasing device 102 can efficiently complete the oil film cleaning task, create good conditions for subsequent track strengthening operations, and ensure the realization of the strengthening effect.

[0055] More specifically, if Figure 4 As shown, two first connecting ears 11 are provided on the lower side of the first connecting plate 10 for connecting to the first end of the connecting rod 30 ; two second connecting ears 21 are provided on the upper side of the second connecting plate 20 for connecting to the second end of the connecting rod 30 .

[0056] A first spherical bearing 31 is installed at the first end of the connecting rod 30, and the bearing is located between the two first connecting ears 11. The first shaft passes through the two first connecting ears 11 and the first spherical bearing 31, so as to realize the rotational connection between the first connecting plate 10 and the connecting rod 30. Similarly, a second spherical bearing 32 is installed at the second end of the connecting rod 30, and the bearing is located between the two second connecting ears 21. The second shaft passes through the two second connecting ears 21 and the second spherical bearing 32, so as to realize the rotational connection between the second connecting plate 20 and the connecting rod 30.

[0057] The above-mentioned technical means not only ensure the stability of the connection, but also endow the track oil removal device 102 with flexible adjustment capabilities in three-dimensional space through the multi-directional rotation capabilities of the spherical bearings, so that it can better adapt to the complex shape and unevenness of the track, thereby ensuring that the oil removal device always maintains close contact with the track surface and efficiently removes the oil film on the inner corners and inclined surfaces of the track.

[0058] Preferably, the connecting rod 30 adopts a segmented telescopic structure, specifically including a fixed rod c3, a first telescopic rod c1 and a second telescopic rod c2, so that the length of the connecting rod 30 can be adjusted according to the actual conditions of the track, so as to better adapt to the unevenness and curve changes of the track.

[0059] The first spherical bearing 31 is installed at the outer end of the first telescopic rod c1 and is connected to the first connecting plate 10 through the first axis to achieve multi-directional rotation; the second spherical bearing 32 is installed at the outer end of the second telescopic rod c2 and is connected to the second connecting plate 20 through the second axis, and also has multi-directional rotation capability.

[0060] In order to ensure the stability of the connecting rod 30 after adjustment, a first locking piece is provided between the fixed rod c3 and the first telescopic rod c1, and a second locking piece is provided between the fixed rod c3 and the second telescopic rod c2. Through the fixing effect of the locking piece, the connecting rod 30 can remain stable after being adjusted to a suitable length, ensuring the close contact between the track degreasing device 102 and the track surface and efficient degreasing operation during operation.

[0061] like Figure 2 and Figure 3 As shown, the track degreasing device 102 includes a frame 40 that can move along the track, and the frame 40 is provided with a first degreasing mechanism 01, a second degreasing mechanism 02 and a cleaning mechanism 03. The frame 40 not only provides a stable installation foundation for the degreasing mechanism, but also ensures that the degreasing operation can cover various key parts of the track through its flexible mobility.

[0062] On the frame 40, the first oil removal mechanism 01, the second oil removal mechanism 02 and the cleaning mechanism 03 are arranged in sequence according to the operation process. This phased oil removal design fully considers the distribution characteristics and removal difficulty of the rail oil film, and realizes efficient and thorough oil film cleaning through targeted mechanism configuration.

[0063] The first oil removal mechanism 01 focuses on removing the oil film at the rail fillet f4. The rail fillet f4 is the key area for rail strengthening operations, but due to its complex geometry and the strong adhesion of the oil film, it is difficult to clean. The first oil removal mechanism 01, through its unique structure, can accurately fit the curved surface of the rail fillet, efficiently remove the oil film in this area, and provide good surface conditions for subsequent strengthening operations.

[0064] The second oil removal mechanism 02 cleans the oil film on the track slope f5. The track slope f5 is also a key area for oil film accumulation, and due to its large inclination angle, the removal of the oil film requires special treatment. The second oil removal mechanism 02 can fit the track slope closely through its adaptive technical means, effectively remove the oil film in this area, and further improve the cleanliness of the track surface.

[0065] The cleaning mechanism 03 is located at the rear of the first oil removal mechanism 01 and the second oil removal mechanism 02, and serves as a further cleaning link for the track oil film. After the first two oil removal processes, the oil film on the track surface has been mostly removed, but there may still be a small amount of residue. The cleaning mechanism 03 uses its efficient cleaning ability to perform the final deep cleaning of the track surface, ensuring that there is no oil film residue on the track surface, providing an absolutely clean surface condition for subsequent track strengthening operations.

[0066] Through this phased and targeted oil removal technical solution, the track oil removal device 102 can not only efficiently remove the oil film on the track surface, but also ensure the stability and reliability of the oil removal operation, thereby significantly improving the overall effect of the track strengthening operation.

[0067] In addition, a rolling support device 41 is provided on the frame 40, and the frame 40 is intended to provide stable support and precise positioning for the oil removal mechanism, and at the same time achieve smooth movement along the track through the rolling support device 41. The frame 40 is composed of a top plate d1, a left wall d2, a right wall d3, a front support plate d4 and a rear support plate d5, forming a strong and flexible support structure.

[0068] The left wall d2 and the right wall d3 are the supporting structures on both sides of the frame 40, which play the role of bearing and fixing the oil removal mechanism, and provide an installation position for the rolling support device 41. The left wall d2 is composed of the upper left crossbeam d21, the left front support rod d23, the left rear support rod d24 and the lower left crossbeam d22. The left front support rod d23 and the left rear support rod d24 are connected between the upper left crossbeam d21 and the lower left crossbeam d22 to form a stable supporting frame. The structure of the right wall d3 is symmetrical with the left wall d2, and is composed of the upper right crossbeam d31, the right front support rod d33, the right rear support rod d34 and the lower right crossbeam d32. The right front support rod d33 and the right rear support rod d34 are connected between the upper right crossbeam d31 and the lower right crossbeam d32. The top plate d1 connects the upper left crossbeam d21 and the upper right crossbeam d31, further enhancing the overall stability of the frame.

[0069] The rolling support device 41 is an important part of the frame 40, and its function is to contact the track f through multiple roller assemblies to provide stable support and flexible movement for the frame 40. The rolling support device 41 includes a left roller assembly 411, a right roller assembly 412, a lower left roller assembly 413, a lower right roller assembly 414 and an upper roller assembly 415. The left roller assembly 411 and the lower left roller assembly 413 are installed on the left wall d2, wherein the left roller assembly 411 abuts against the left side f2 of the track f, and the lower left roller assembly 413 abuts against the left bottom surface f31 of the track f. The right roller assembly 412 and the lower right roller assembly 414 are installed on the right wall d3, wherein the right roller assembly 412 abuts against the right side f2 of the track f, and the lower right roller assembly 414 abuts against the right bottom surface f32 of the track f. The upper roller assembly 415 is mounted on the front support plate d4 and the rear support plate d5, and acts on the top surface f1 of the track f.

[0070] The above technical means not only ensure the stability and mobility of the frame 40 on the track, but also disperse the contact pressure between the frame and the track through multi-point support, reduce wear and extend the service life of the equipment. At the same time, the multi-point contact design of the rolling support device 41 enables the frame 40 to better adapt to the unevenness of the track, ensuring that the oil removal mechanism always maintains the best contact state with the track surface during operation, thereby achieving efficient and stable oil film removal effect.

[0071] like Figure 5 and Fig. 9As shown, the first oil removal mechanism 01 includes a first fixed frame 011 and a flexible scraper blade 51 mounted on the first fixed frame 011. The flexible scraper blade 51 is made of a stainless steel sheet with a thickness of 0.3-0.6 mm. This material selection not only ensures the strength and durability of the blade, but also makes it flexible enough to adapt to the complex curved surface of the track fillet f4. The flexible scraper blade 51 is fan-shaped, which allows the flexible scraper blade 51 to be relatively bent when in use, so as to better fit the surface of the track fillet f4. The blade 511 of the flexible scraper blade 51 has been specially treated to ensure its sharpness and wear resistance, and can efficiently scrape the oil film on the track surface.

[0072] The flexible scraper blade 51 is fixed and operated by two operating arms e. The front end of the operating arm e is provided with a clamping claw e1, which is used to grab the two sides of the flexible scraper blade 51, thereby driving the blade to move along the track to scrape off the oil film. The rear end of the operating arm e is connected to the mounting seat through a connecting shaft, and a first spring s1 is arranged on the connecting shaft. The elastic potential energy of the first spring s1 provides a stable supporting force for the flexible scraper blade 51, ensuring that the flexible scraper blade 51 always acts on the track fillet f4 with appropriate pressure, thereby achieving efficient oil film removal. At the same time, the elastic characteristics of the spring also give the flexible scraper blade 51 a certain degree of floatability and flexibility, so that it can be fine-tuned according to the unevenness of the track surface, thereby ensuring full contact with the track surface while avoiding damage to the blade itself or the track f due to excessive pressure.

[0073] In addition, if Figure 6 , Figure 8 As shown, the second oil removal mechanism 02 is one of the key components in the track oil removal device 102, which is designed to efficiently remove the oil film on the track slope f5. The mechanism includes a second fixed frame 021 and a plurality of blades 52 mounted thereon. Each blade 52 is mounted on the fixed frame via a connecting shaft b, and the connecting shaft b is equipped with a second spring s2. The second spring s2 provides a continuous oblique pressing force for the blade 52 to ensure that the blade can fit tightly against the track slope f5 during operation. When the rail vehicle 101 moves forward, the blade 52 is pushed forward and moves along the track slope, thereby scraping off the oil film.

[0074] More specifically, the blade layout of the second oil removal mechanism 02 is carefully designed to achieve a more efficient and thorough oil film removal effect. The mechanism includes four blades, namely a first blade 521, a second blade 522, a third blade 523 and a fourth blade 524. The first blade 521 and the second blade 522 are arranged in parallel in the first row, while the third blade 523 and the fourth blade 524 are arranged in parallel in the second row behind the first row. A first gap is left between the first blade 521 and the second blade 522, and a second gap is left between the third blade 523 and the fourth blade 524. The third blade 523 is located at the rear of the first gap.

[0075] In actual use, the blades in the first row and the blades in the second row are arranged in a front-to-back staggered manner. This staggered design enables the first blade 521 in the first row to make up for the second gap in the second row, while the fourth blade 524 in the second row can make up for the first gap in the first row. Through this unique layout, the blades can form a continuous scraping path on the track slope, ensuring that the oil film is fully and thoroughly removed, significantly improving the efficiency and effect of oil removal.

[0076] Furthermore, if Figure 7 As shown, the cleaning mechanism 03 is the last process in the rail degreasing device 102, and its main function is to deeply clean the rail surface after the previous degreasing treatment to ensure that the oil film on the rail surface is completely removed. The cleaning mechanism 03 is composed of a mounting plate n and a plurality of wire brushes m, each of which is composed of a brush handle m1 and a wire brush head m2.

[0077] The wire brush heads m2 are made of high-strength, wear-resistant steel wire material with good elasticity and cleaning ability. These wire brush heads m2 cover key areas of the track, including the rounded corners f4 and bevel f5 of the track. This ensures that the wire brush heads m2 can penetrate into the tiny gaps on the track surface, deeply clean the residual oil film, and further remove dirt and residue on the track surface.

[0078] In actual operation, when the rail vehicle 101 drives the rail degreasing device 102 to move along the rail, the wire brush head m2 of the cleaning mechanism 03 cleans the rail surface, and the residual oil film and impurities on the rail surface are completely removed through the elastic deformation and friction of the wire. This deep cleaning not only improves the cleanliness of the rail surface, but also provides more reliable surface conditions for subsequent rail strengthening operations.

[0079] Through the efficient cleaning of the cleaning mechanism 03, the oil film residue on the track surface is reduced to a minimum, thereby significantly improving the effect of the track strengthening operation, extending the service life of the track, and ensuring the safety and reliability of rail transportation.

[0080] In addition, an efficient method of removing track oil film ensures that the track surface oil film is completely removed through a phased, multi-stage oil removal process, providing the best conditions for subsequent track strengthening operations. The specific method of removing track oil film is as follows:

[0081] First, the rail vehicle 101 is started to drive the rail degreasing device 102 to move smoothly along the rail f to the area to be treated. The position of the degreasing device is accurately determined through the vehicle's positioning system and navigation device to ensure that it can fully cover the rail surface to be treated, laying the foundation for efficient degreasing operations.

[0082] Subsequently, the first oil removal mechanism 01 and the second oil removal mechanism 02 are started in sequence. The first oil removal mechanism 01 is equipped with a flexible scraping blade 51. The blade, supported by the elastic potential energy of the first spring s1, can closely fit the complex curved surface of the rail fillet f4 and efficiently scrape off the oil film. The second oil removal mechanism 02 includes a plurality of blades 52, each of which is installed through a connecting shaft b with a second spring s2. The spring provides a continuous oblique pressing force for the blade to closely fit the rail inclined surface f5. The blades are arranged in a staggered manner to form a continuous scraping path, ensuring that the oil film on the rail inclined surface is completely removed, significantly improving the efficiency and effect of oil removal.

[0083] Next, the cleaning mechanism 03 is started to deeply clean the track surface after the first two oil removal processes. The cleaning mechanism 03 includes a plurality of wire brushes m, whose brush heads cover the fillet f4 and the inclined surface f5 of the track. Driven by the rail vehicle 101, the wire brush head cleans and completely removes the oil film and impurities remaining on the track surface through the elastic deformation and friction of the wire, ensuring that there is no residue on the track surface, providing an absolutely clean surface condition for subsequent strengthening operations.

[0084] After completing the above oil film removal process, the rail vehicle 101 continues to move along the track f and enters the subsequent track strengthening operation stage. At this time, the track surface has been processed by the multi-stage oil removal mechanism to achieve a clean and oil-free state, which can effectively prevent the oil film from weakening the laser strengthening effect, thereby significantly improving the overall effect of the track strengthening operation, extending the service life of the track, and ensuring the safety and reliability of rail transportation.
