[0040] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0041] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0042] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0045] like Figures 1 to 8As shown, according to the first aspect of the utility model, there is provided a cleaning device 1 applied to a vehicle, comprising: a skeleton structure, a transmission mechanism and a roller brush; the transmission mechanism and the roller brush are respectively mounted on the skeleton structure, and the roller brush is connected to the driven end of the transmission mechanism; the cleaning device 1 is suitable for being mounted on the vehicle through the skeleton structure, so that the driving end of the transmission mechanism can be in frictional contact with the running wheel 2 of the vehicle to drive the roller brush to roll.

[0046] Specifically, in the utility model, a cleaning device 1 is provided, which can be assembled on a vehicle, especially a rail vehicle, through a skeleton structure, and the driving end of the transmission mechanism is in frictional contact with the vehicle running wheel 2, so that when the vehicle is moving, through the friction of the running wheel 2, the transmission mechanism can transmit the friction force to the driven end of the transmission mechanism through the driving end, thereby driving the roller brush to roll and achieve the purpose of cleaning.

[0047] In the above structure, the skeleton structure can be assembled on the chassis or suspension beam of the vehicle and other structures, and can usually be assembled by bolts to achieve the purpose of disassembly, maintenance and replacement. In addition, the specific structure of the transmission structure can be designed according to the actual transmission form, and the transmission form can be selected, for example, belt 4 transmission, chain transmission and gear transmission, etc., and the present utility model does not limit this. Since the cleaning device 1 needs to clean the debris or snow in front of the vehicle in the moving map, the cleaning device 1 is usually installed at the front end of the vehicle. If there are other special uses, it can also be assembled according to actual needs.

[0048] When the cleaning device 1 provided in this embodiment is installed on a vehicle, the running wheels 2 of the vehicle roll under the action of the traction force of the vehicle, and provide driving force to the driving end of the cleaning device 1 through friction, so that the brush 7 can achieve rolling cleaning. On the one hand, compared with the flat push cleaning form in the prior art, it can improve the cleaning efficiency and cleaning effect, and when the running speed of the train increases, the rotation speed of the roller brush can also be increased accordingly, so that the cleaning ability is enhanced, and the cleaning efficiency is further improved.

[0049] On the other hand, the cleaning device 1 is installed in front of the running wheels 2 of the vehicle. Figure 2 and Figure 3 , close enough to the direction of the train, so its travel path is relatively consistent with the vehicle travel path, and there is no need to set up a separate guide system, and the driving wheel 3 of the device acts as the driven wheel 5 of the running wheel 2 to provide power for the cleaning device 1, and there is no need to set up an additional power system, so the design structure of the device is simpler, easy to use, highly lightweight, and has lower cost. Among them, the running wheel 2 of the vehicle usually refers to the wheel that can drive the vehicle to move.

[0050] Alternatively, if Figure 1As shown, the transmission mechanism includes a driving wheel 3, a transmission member 4 and a driven wheel; the driving wheel 3 is connected to the driven wheel 5 through the transmission member 4, the driven wheel 5 is fixedly connected to the roller brush, the driving wheel 3 is assembled on the skeleton structure, and can be in frictional contact with the running wheel 2 to drive the roller brush to rotate.

[0051] Specifically, in this embodiment, the transmission mechanism is designed to be a form in which the driving wheel 3 drives the driven wheel 5 through the transmission member 4, that is, the driving wheel 3 is set to be in friction contact with the running wheel 2 of the vehicle, so that the running wheel 2 can drive the driving wheel 3 to rotate through friction, and then the driving force is transmitted to the driven wheel 5 through the transmission of the transmission member 4, so that the driven wheel 5 can drive the roller to rotate, thereby achieving the function of rolling cleaning. Among them, the transmission member 4 can be in the form of a belt, a chain, a gear, etc., and the form of belt transmission has a simple structure and does not require complex transmission parts, which is conducive to the simplification of the cleaning device 1.

[0052] In practical applications, the friction between the running wheel 2 and the driving wheel 3 can be adjusted by adjusting the interference between the driving wheel 3 and the running wheel 2, so that the driving wheel 3 will not get stuck due to excessive friction or fail to drive the roller brush to roll due to too little friction.

[0053] Alternatively, if Figure 1 As shown, the roller brush includes a rotating shaft 6 and a brush 7. The brush 7 is arranged on the rotating shaft 6. The brushes 7 are arranged in rows along the axial direction of the rotating shaft 6 and in multiple rows radially along the radial direction of the rotating shaft 6.

[0054] Specifically, in the present embodiment, the brushes 7 are arranged in rows and multiple rows are arranged, which can further improve the cleaning efficiency and cleaning effect of the entire roller brush.

[0055] Alternatively, if Figure 1 As shown, the skeleton structure includes a mounting bracket 8, a first assembly axis 9 and a second assembly axis 10, and the first assembly axis 9 and the second assembly axis 10 are respectively fixed at the front and rear ends of the mounting bracket 8; the roller brush is correspondingly connected to the two ends of the first assembly axis 9, and the driving wheel 3 is assembled on the second assembly axis 10.

[0056] Specifically, in the present embodiment, the driving wheel 3 and the driven wheel 5 are respectively mounted at the corresponding positions of the first assembly shaft 9 and the rotating shaft 6, so that the transmission assembly can transmit force more effectively. Usually, the driving wheel 3 and the driven wheel 5 are arranged on the same side of the frame and the brush 7 to facilitate the installation of the belt 4, and the installation of the mounting bracket 8 is conducive to the assembly of the cleaning device 1 on the vehicle. In addition, in the present embodiment, the brush 7 is made to interfere with the action surface (such as the track beam), so that the brush 7 can have a better cleaning effect when the roller brush is rotating. For example, when the cleaning device 1 is assembled on a rail vehicle for snow removal, there is a certain amount of interference between the brush 7 and the surface of the track beam, so that the brush 7 can better remove the residual snow in the gap of the track coating. Compared with the cleaning device 1 in the prior art, its ability to remove snow and cleanliness are stronger.

[0057] Alternatively, if Figure 1 As shown, the roller brush includes a rotating shaft 6 and a brush 7, and the brush 7 is arranged on the rotating shaft 6. The two ends of the rotating shaft 6 and the first assembly shaft 9 are respectively connected correspondingly through a group of adjustment components, and the adjustment components include a rocker rod 11 and a locking mechanism; the first end of the rocker rod 11 is rotatably assembled on the end of the rotating shaft 6, and the second end is assembled on the end of the first assembly shaft 9 through the locking mechanism, and the locking mechanism enables the rocker rod 11 to have a swinging state and a locking state relative to the first assembly shaft 9; when the rocker rod 11 is in the swinging state, the rotating shaft 6 can rotate around the axial direction of the first assembly shaft 9 to adjust the interference amount between the brush 7 and the action surface; when the rocker rod 11 is in the locking state, the rotating shaft 6 can be locked relative to the first assembly shaft 9 to keep the set interference amount between the brush 7 and the action surface.

[0058] Specifically, in actual application, if the cleaning device 1 is used for too long, the brush 7 will be worn to a certain extent, which will cause the interference between the brush 7 and the action surface to decrease, resulting in poor cleaning effect. In this embodiment, the second end of the swing rod 11 is assembled at the end of the first assembly shaft 9 through a locking mechanism, so that the swing rod 11 can swing or lock relative to the first assembly shaft 9, thereby adjusting the interference between the brush 7 and the action surface, improving the service life of the cleaning device 1, and ensuring the cleaning effect of the cleaning device 1.

[0059] Furthermore, in the above structure, a connecting rod 22 may be provided, the two ends of which are respectively mounted at the outermost ends of the second assembly axis 10 and the rotating axis 6, and the two ends of the connecting rod 22 may respectively rotate around the second assembly axis 10 and the rotating axis 6, and when the swing arm 11 is in a swinging state, the connecting rod 22 may also rotate to avoid affecting the regulating function of the swing arm 11. In this embodiment, the provision of the connecting rod 22 may improve the stability of the entire transmission mechanism.

[0060] Alternatively, if Figure 1 and Figure 4 As shown, the locking mechanism includes a fixing plate 12, a first fastener 14 and a first locking member 15. The second end of the swing rod 11 and the fixing plate 12 are sequentially assembled on the end of the first assembly shaft 9 through the first fastener 14. A plurality of locking holes 13 are provided on the fixing plate 12 and the second end of the swing rod 11.

[0061] When the first locking member 15 is only inserted into the locking hole 13 of the fixed disk 12, the rocker arm 11 is in the swinging state, and when the first locking member 15 is simultaneously inserted into the locking holes 13 on the fixed disk 12 and the second end of the rocker arm 11, the rocker arm 11 is in the locked state.

[0062] Specifically, in this embodiment, the first locking member 15 is inserted into a locking hole 13 on the fixed disk 12 and a locking hole 13 on the second end of the swing rod 11 at the same time, so that the swing rod 11 is in a locked state, that is, the brush 7 and the action surface can maintain a set interference amount to ensure the cleaning effect. If it is necessary to adjust the interference amount between the brush 7 and the action surface, it is only necessary to pull out the first locking member 15 until it is only inserted into the locking hole 13 on the fixed disk 12, or directly pull it out until it is separated from the locking hole 13 of the fixed disk 12. At this time, the swing rod 11 can rotate around the first assembly axis 9, thereby driving the brush 7 on the rotating shaft 6 to move upward or downward to adjust the interference amount between the brush 7 and the action surface. After the adjustment is appropriate, the first locking member 15 is inserted into the locking hole 13 on the fixed disk 12 and the locking hole 13 set on the second end of the swing rod 11 in sequence, and the locking of the swing rod 11 can be achieved.

[0063] In the above embodiment, the first locking member 15 can be a locking pin or a bolt with external threads. When the first locking member 15 is a bolt with external threads, an internal thread can be set in the locking hole 13. When locking, it is only necessary to tighten the bolt into the locking hole 13. This locking form can prevent the locking member from falling off during the cleaning process, thereby improving the reliability of the locking.

[0064] Alternatively, if Figure 1 , Figure 5 and Figure 7 As shown, the locking mechanism includes a second fastener 16 and a second locking member 17, and the second end of the rocker arm 11 and the second locking member 17 are assembled on the end of the first assembly shaft 9 in sequence through the second fastener 16; a plurality of locking holes 13 are provided on the second end of the rocker arm 11, and a first protrusion 18 facing the second end of the rocker arm 11 is provided on the second locking member 17, and when the first protrusion 18 is inserted into the locking hole 13, the rocker arm 11 is in the locked state.

[0065] Specifically, in this embodiment, the second locking member 17 is provided with a first protrusion 18 on one side facing the second end of the swing rod 11, and the first protrusion 18 is inserted into the lock hole 13 to achieve the locking of the swing rod 11. If the interference amount between the brush 7 and the action surface needs to be adjusted, it is only necessary to loosen the second fastener 16 to make the first protrusion 18 withdraw from the lock hole 13. Among them, the number of the first protrusion 18 can be set to ensure the locking effect and improve the reliability of the locking.

[0066] Alternatively, if Figure 1 , Figure 6 and Figure 8 As shown, the locking mechanism includes a third fastener 19 and a third locking member 20, and the second end of the rocker arm 11 and the third locking member 20 are sequentially assembled on the end of the first assembly shaft 9 through the third fastener 19; the second end of the rocker arm 11 is provided with external gear teeth along its periphery, and the third locking member 20 is provided with a second protrusion 21 facing the second end of the rocker arm 11, and the second protrusion 21 is provided with internal gear teeth, and when the internal gear teeth are meshed with the external gear teeth, the rocker arm 11 is in the locked state.

[0067] Specifically, in this embodiment, the locking of the swing rod 11 is achieved by the meshing of the inner gear teeth provided on the second protrusion 21 of the third locking member 20 and the outer gear teeth provided on the second end of the swing rod 11. If the interference amount between the brush 7 and the action surface needs to be adjusted, it is only necessary to loosen the third fastener 19 so that the third locking member 20 moves outward to the side away from the second end of the swing rod 11 until the inner gear teeth are separated from the outer gear teeth. The structural form of achieving locking through the meshing of gear teeth can not only ensure the locking effect, but also avoid the risk of the second protrusion 21 breaking, thereby improving the reliability of the locking. In this structure, the number of the second protrusions 21 can also be set to multiple to further improve the locking effect.

[0068] Alternatively, if Figure 3 The rolling direction of the roller brush shown in FIG. Figure 3 Y direction) and the traveling direction of the running wheel 2 ( Figure 3 The X direction has a set angle, and the range of the set angle is 5° to 50°.

[0069] Specifically, in this embodiment, a certain angle is set between the rolling direction of the roller brush and the traveling direction of the running wheel 2. For example, in a rail vehicle, the rolling direction of the roller brush is arranged at a certain inclination angle with the rail beam, so that during the rotating cleaning process, the roller brush can make the cleaned debris leave the travel track of the rail vehicle, thereby achieving a cleaning effect on the rail beam surface. In practical applications, this set angle can be set between 5° and 50° to ensure the cleaning effect. Preferably, this set angle can be set between 10° and 30°.

[0070] Optionally, the contact surface between the driving end and the running wheel 2 is an inclined surface, so that the rolling direction of the roller brush and the moving direction of the running wheel 2 can have the set angle.

[0071] Specifically, in actual applications, the driving end contacts the running wheel 2 so that the running wheel 2 can transmit the driving force to the driven end through the driving end during movement, and the contact surface between the driving end and the running wheel 2 is an inclined surface, so that the angle between the rolling direction of the roller brush and the traveling direction of the running wheel 2 can be adjusted by the inclination angle of the inclined surface.

[0072] like Figures 1 to 3 As shown, the driving end is designed in the form of a driving wheel 3, and the angle can be adjusted by adjusting the inclination of the contact surface between the driving wheel 3 and the running wheel 2. This design makes it easier to adjust the angle and the structure is simpler.

[0073] According to the second aspect of the present invention, referring to Figure 2 and Figure 3 , provides a rail vehicle, comprising: a vehicle body and the cleaning device 1 described in the first aspect, wherein the cleaning device 1 is assembled on the vehicle body through the skeleton structure.

[0074] Specifically, in the present embodiment, the provided rail vehicle is equipped with the cleaning device 1 provided in the first aspect of the present utility model, which is improved from the horizontal snow pushing of the common technology to the rotary cleaning on the rail beam, and can provide a greater cleaning force and cleaning speed than the brush 7 of the same structural size, thereby greatly improving the cleaning efficiency, reducing the risk of derailment of the rail vehicle, and improving the safety performance of the rail vehicle.

[0075] In addition, the cleaning device 1 is installed in front of the running wheel 2 of the vehicle, which is close enough to the direction of travel of the train. Therefore, its travel path is relatively consistent with the vehicle travel path, and there is no need to set up a separate guide system. The driving wheel 3 of the device acts as the driven wheel 5 of the running wheel 2 to provide power for the cleaning device 1. There is no need to set up an additional power system. Therefore, the design structure of the device is simpler, easy to use, lightweight, and has a lower cost.

[0076] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
