Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] See Figure 1 and Figure 2 This application provides a dust removal device, which includes a enclosure mechanism 10, a dust removal mechanism, and a drive mechanism 30. The enclosure mechanism 10 is fixed to the frame of a rail grinding vehicle and surrounds the outer periphery of the grinding mechanism of the rail grinding vehicle. The dust removal mechanism is disposed on the enclosure mechanism 10 and includes a first blowing part 21, which is configured to blow air toward the grinding mechanism. The first blowing part 21 is movably disposed relative to the enclosure mechanism 10 to blow air at different positions of the grinding mechanism. The drive mechanism 30 is disposed on the enclosure mechanism 10 and is drivenly connected to the first blowing part 21 to drive the first blowing part 21 to move relative to the enclosure mechanism 10.

[0049] Applying the solution of this application, the first blowing unit 21 is configured to blow air towards the grinding mechanism of the rail grinding vehicle, and the first blowing unit 21 is movably arranged relative to the enclosure mechanism 10. This arrangement allows the first blowing unit 21 to move relative to the grinding mechanism during operation, blowing air to different positions on the grinding mechanism. The first blowing unit 21 is driven by the drive mechanism 30 to blow away high-temperature dust covering different positions on the grinding mechanism, reducing the accumulation of high-temperature dust on the grinding mechanism, lowering the risk of overheating caused by the accumulation of high-temperature dust, and extending the service life of the grinding mechanism. Simultaneously, the enclosure mechanism 10 can block dust, reducing the outward diffusion of dust.

[0050] In actual use, the first blowing part 21 can be positioned above the polishing mechanism, so that the first blowing part 21 blows the surface of the polishing mechanism from top to bottom, and uses airflow to disperse the high-temperature dust attached to the polishing mechanism.

[0051] In some embodiments, the drive mechanism 30 includes a rocker arm 323, the first end of which is oscillating around a preset axis. A first blowing part 21 is disposed at the second end of the rocker arm 323, and the rocker arm 323 drives the first blowing part 21 to perform an arc-shaped motion. Driven by the drive mechanism 30, the rocker arm 323 oscillates around the preset axis, causing the first blowing part 21 to move along an arc-shaped path, thereby blowing the surface of the grinding mechanism. This arrangement allows the movement trajectory of the first blowing part 21 to cover a larger blowing range, improving the blowing effect on the grinding mechanism.

[0052] In some embodiments, the preset axis extends vertically and the rocker arm 323 extends horizontally. In actual use, the first blowing part 21 blows the top of the polishing mechanism.

[0053] In some embodiments, the preset axis extends horizontally and the rocker arm 323 extends vertically. In actual use, the first blowing part 21 blows the side of the polishing mechanism.

[0054] See Figures 1 to 3 In some embodiments, the enclosure mechanism 10 includes a side enclosure 11 with a clearance hole 1101. The drive mechanism 30 is located on the side of the side enclosure 11 away from the rail grinding vehicle. The first blowing part 21 passes through the clearance hole 1101 and is located on the side of the side enclosure 11 facing the grinding mechanism. This arrangement ensures that the drive mechanism 30 and the grinding mechanism are located on opposite sides of the side enclosure 11, reducing the impact of dust on the drive mechanism 30 during grinding and improving the stability of the drive mechanism 30's operation.

[0055] In some embodiments of this application, the side enclosure 11 is a vertically arranged plate-like structure.

[0056] Furthermore, the clearance hole 1101 extends horizontally and along the length of the side enclosure 11, and the extension length of the clearance hole 1101 is adapted to the range of motion of the first blowing part 21. This arrangement can reduce the possibility of dust escaping outward from the clearance hole 1101.

[0057] In some embodiments, the dust removal device further includes a mounting portion 40, which is located on the side of the side enclosure 11 away from the rail grinding vehicle. The drive mechanism 30 includes a drive member 31 and a transmission assembly 32. The drive member 31 is mounted on the mounting portion 40 and has an output shaft that extends vertically. The transmission assembly 32 includes a crank 321, a connecting rod 322, and a rocker arm 323. The two ends of the connecting rod 322 are hinged to the first ends of the crank 321 and the rocker arm 323, respectively. The crank 321 is fixed to the output shaft and extends radially along the output shaft. The first end of the rocker arm 323 is hinged to the mounting portion 40. When the drive member 31 is activated, the output shaft drives the crank 321 to rotate, which in turn transmits the motion to the rocker arm 323 through the connecting rod 322, causing the rocker arm 323 to oscillate back and forth around a preset axis, thereby driving the first blowing part 21 to move along an arc path.

[0058] In this embodiment, the driving component 31 includes a motor and a reducer. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer forms the output shaft of the driving component 31.

[0059] In some embodiments, the dust removal device further includes a first protective cover 50, which is disposed on the side of the enclosure mechanism 10 away from the grinding mechanism, and the drive mechanism 30 is located inside the first protective cover 50. This arrangement can reduce the impact of external dust and impurities on the drive mechanism 30, improve the cleanliness of the working environment of the drive mechanism 30, and extend the service life of the drive mechanism 30.

[0060] In some embodiments of this application, the number of first blowing parts 21 is set to multiple, and the multiple first blowing parts 21 are arranged at intervals along the length direction of the side enclosure 11. The drive mechanism 30, the mounting part 40 and the first protective cover 50 are respectively provided corresponding to the first blowing parts 21.

[0061] In some embodiments, the enclosure mechanism 10 includes a dustproof enclosure and a fire baffle 13. The dustproof enclosure includes a side enclosure 11 and a top enclosure 12 connected to each other. The side enclosure 11 and the top enclosure 12 are arranged at an angle. The first blowing part 21 is arranged opposite to the side enclosure 11. The fire baffle 13 is arranged below the side enclosure 11.

[0062] The top enclosure 12 is a horizontally arranged plate-like structure, and it is vertically connected to the side enclosures 11. In actual use, the top enclosure 12 is located above the grinding mechanism, and the side enclosures 11 are located to the side of the grinding mechanism. Together, they form a semi-enclosed protective structure to reduce dust diffusion.

[0063] Furthermore, the fire baffle 13 is located below the side enclosure 11 to block the falling of sparks and high-temperature debris generated during the grinding process, thereby reducing or avoiding the splashing of sparks and high-temperature debris.

[0064] See Figure 3 and Figure 4 In some embodiments, the dust removal device further includes a second blowing section 22, which is disposed on the dustproof enclosure and configured to blow air toward the side of the fire baffle 13 facing the grinding mechanism. The second blowing section 22 can blow air onto the surface of the fire baffle 13, promptly removing high-temperature dust from the surface of the fire baffle 13, reducing the possibility of high-temperature dust on the surface of the fire baffle 13 cooling down, solidifying, and adhering to the fire baffle 13, and reducing the risk of heat damage or deformation of the fire baffle 13.

[0065] In some embodiments, a ventilation gap 101 is provided between the fire baffle 13 and the side enclosure 11 in the vertical direction. The second blowing part 22 is disposed on the side of the side enclosure 11 away from the grinding mechanism, and the air outlet of the second blowing part 22 blows air towards the side of the fire baffle 13 facing the grinding mechanism through the ventilation gap 101. This arrangement, so that the second blowing part 22 is located on the side of the side enclosure 11 away from the grinding mechanism, can avoid the second blowing part 22 being directly exposed to the high temperature and dust environment, thereby improving the stability and durability of the operation of the second blowing part 22.

[0066] This solution does not limit the number of the second purging section 22. In the embodiments of this solution, there are multiple second purging sections 22, which are distributed at intervals along the length direction of the side enclosure 11.

[0067] Furthermore, the enclosure mechanism 10 also includes a connecting rod 14, the top end of which is connected to the bottom end of the side enclosure 11, and the bottom end is connected to the fire baffle 13, so that a ventilation gap 101 is formed between the side enclosure 11 and the fire baffle 13.

[0068] The bottom end of the connecting rod 14 is detachably connected to the fire baffle 13. This design facilitates the removal of the fire baffle 13 for cleaning or replacement, improving maintenance efficiency.

[0069] See Figure 2 Furthermore, the dust removal mechanism also includes an air supply component, which includes a first air supply pipeline and a first valve disposed on the first air supply pipeline. The first air supply pipeline is connected to the first purging section 21. In addition, a wire hole 501 is provided on the first protective cover 50, through which the first air supply pipeline can extend into the first protective cover 50 and connect with the first purging section 21.

[0070] Furthermore, the gas supply assembly also includes a second gas supply line and a second valve disposed on the second gas supply line, the second gas supply line being connected to the second purging section 22.

[0071] The above configuration allows the first valve to control the working state of the first purging section 21 and the second valve to control the working state of the second purging section 22, thus achieving independent control of the first purging section 21 and the second purging section 22. This facilitates the adjustment of the purging intensity and start / stop timing of the first purging section 21 and the second purging section 22 according to the actual working conditions, thereby improving the flexibility of this solution.

[0072] The first purging part 21 can be a first nozzle, and the second purging part 22 can be a second nozzle.

[0073] In some embodiments of this solution, the operating states of the first valve and the second valve can be controlled manually.

[0074] See Figure 1 and Figure 5 In other embodiments of this solution, the dust removal device further includes a speed detection element 61 and a control system 62. The speed detection element 61 is mounted on the enclosure mechanism 10 and is used to detect the running speed of the rail grinding vehicle. The control system 62 is also mounted on the enclosure mechanism 10 and is communicatively connected to the first valve, the second valve, and the speed detection element 61 to control the working state of the first and second valves according to the running speed of the rail grinding vehicle. This configuration allows for the adjustment of the start / stop and blowing intensity of the first blowing section 21 and the second blowing section 22 according to the traveling speed of the rail grinding vehicle, enabling the dust removal mechanism to match the dust suppression requirements of the rail grinding vehicle at different traveling speeds and achieving intelligent control of the blowing operation.

[0075] Furthermore, the dust removal device also includes a second protective cover 60, which is located on the side of the side enclosure 11 away from the grinding mechanism. The control system 62 and the speed detection element 61 are both located inside the second protective cover 60. This arrangement allows the second protective cover 60 to protect the control system 62 and the speed detection element 61, extending their service life.

[0076] Furthermore, the second protective cover 60 is located between the two first protective covers 50.

[0077] An embodiment of this solution also provides a rail grinding vehicle, which includes a frame, a traveling mechanism, a grinding mechanism, and a dust removal device as described in the above embodiment. The traveling mechanism is mounted on the frame; the grinding mechanism is mounted on the frame; the dust removal device's enclosure mechanism 10 is mounted on the frame and surrounds the outer periphery of the grinding mechanism.

[0078] In summary, this solution has at least the following technical advantages:

[0079] 1. By driving the first blowing part 21 to make arc motion through the driving mechanism 30, the blowing range of the first blowing part 21 on the top of the grinding mechanism can be increased, the accumulation of high temperature dust on the grinding mechanism can be reduced, the working stability of the grinding mechanism can be improved, and the service life of the grinding mechanism can be extended.

[0080] 2. By blowing the surface of the fire baffle 13 toward the grinding mechanism through the second blowing section 22, the accumulation of high-temperature dust on the surface of the fire baffle 13 can be reduced, preventing the fire baffle 13 from deforming due to local overheating and extending the service life of the fire baffle 13.

[0081] 3. The blowing intensity and start / stop timing of the first blowing section 21 and the second blowing section 22 can be adjusted separately according to the running speed of the rail grinding vehicle, so as to match the dust suppression requirements under different working conditions.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
