In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0028] In the present application, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connecting", "fixing" and the like appear, these terms should be interpreted broadly. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] In the present application, unless otherwise explicitly specified and limited, if the first feature is described as "on" or "under" the second feature, etc., it can mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are only for illustrative purposes and do not represent the only implementation.

[0031] According to the vehicle return repair requirement, the train needs to be cleaned almost every day when entering or leaving the warehouse. According to this requirement, the brush group used for cleaning the train has a very high utilization rate. However, the trains entering the warehouse are different, and the widths of the train bodies are also different. When the width of the train body is large, the train body will consume more wool, which will increase the reaction force of the brush car and increase the cleaning difficulty. When the width of the train body is small, the train body will consume less wool, which will cause the train body to be not clean and not thorough. Therefore, when cleaning trains with different widths, the wool consumption of the brush group should be kept within a constant range to improve the cleaning efficiency of the train.

[0032] To this end, an embodiment of the present application provides a brush group mechanism which can be used for side cleaning of vehicles such as high-speed rail, motor train, train, subway and other rail transit vehicles. The brush group mechanism can be installed on the side of the track 20, and of course it can also be used for side cleaning of other vehicles. The structure and use of the brush group mechanism will be described below with the motor train as an example.

[0033] As shown in Figure 1 and Figure 2 , the brush group mechanism 10 includes a mounting unit 100, a swing unit 200 and a limiting unit. The mounting unit 100 is used to mount the rolling brush 700 to the side of the track 20, and has a first mounting position and a second mounting position along the circumference of itself. The first mounting position and the second mounting position are different in distance to the track 20, for example, as shown in Figure 3 and Figure 4 , the distance from the first mounting position to the track 20 is less than the distance from the second mounting position to the track 20, or the distance from the first mounting position to the track 20 is greater than the distance from the second mounting position to the track 20.

[0034] In an embodiment, as shown in Figure 1 , the mounting unit 100 can include a base 110, a stand 120 and a rotating shaft structure 130. The stand 120 is arranged on the base 110, and the rotating shaft structure is arranged on the stand 120 and can drive the swing unit 200 to rotate around the stand 120. The base 110 can be screwed to the ground or the table surface on the side of the track 20 by using screws or other threaded fasteners, and the stand 120 is screwed to the top of the base 110 by using screws or other threaded fasteners. It should be noted that, in order to clearly show the structure of the mounting unit 100 and the swing unit 200, Figure 1 , the brush group mechanism 10 shown does not show the limiting unit, wherein the limiting unit is installed on the mounting area A above the base 110.

[0035] Alternatively, the rotating shaft structure 130 includes a connecting plate, a rotating shaft and a driving member. The connecting plate is provided in two, and the two connecting plates are arranged on the outer circumferential surface of the stand 120 in the axial direction of the stand 120. The rotating shaft is rotatably arranged between the two connecting plates, and the driving member is arranged on one of the connecting plates and can drive the rotating shaft to rotate. The driving member can be a pneumatic cylinder or a pneumatic actuator.

[0036] The swing unit 200 is used to mount the rolling brush 700 and is rotatably connected with the mounting unit 100, so that the rolling brush 700 swings relative to the mounting unit 100 between the first mounting position and the second mounting position. The rolling brush 700 can be mounted to the first mounting position or the second mounting position according to the width of the train, for example, when cleaning a train with a small width, the rolling brush 700 can be swung to the second mounting position or the first mounting position to reduce the distance between the rolling brush 700 and the track 20, so as to prevent the train body from being too small in the amount of hair, and when cleaning a train with a large width, the rolling brush 700 can be swung to the first mounting position or the second mounting position to increase the distance between the rolling brush 700 and the track 20, so as to prevent the train body from being too large in the amount of hair, so that the amount of hair of the brush group can be ensured within a constant range, thereby improving the cleaning efficiency of the train.

[0037] In an embodiment, as shown in Figure 1 The swing unit 200 includes a swing arm 210, a brush shaft, and a first driving motor 220; the swing arm 210 is provided in two, and the two swing arms 210 are arranged on the upper and lower sides of the rotating shaft; the brush shaft is rotatably arranged between the two swing arms 210 and is provided with the rolling brush 700; and the first driving motor 220 is arranged on the swing arm 210 on the lower side of the rotating shaft and can drive the brush shaft to rotate.

[0038] Optionally, as shown in Figure 1 The swing unit 200 further includes two reinforcing rib plates 230, each of which is connected with the rotating shaft and the corresponding swing arm 210. The reinforcing rib plate 230 is used to enhance the connection strength of the rotating shaft and the swing arm 210. The reinforcing rib plate 230 can be triangular, trapezoidal, or rectangular, without specific limitation. The reinforcing rib plate 230 can be connected with the rotating shaft and the swing arm 210 by welding, screwing, or the like.

[0039] The limiting unit is arranged on the base 110 of the mounting unit 100 and can include a first limiting assembly 300 and a second limiting assembly 400. The first limiting assembly 300 can limit the swing unit 200 in the circumferential direction at the first mounting position, and the second limiting assembly 400 can limit the swing unit 200 in the circumferential direction at the second mounting position. The second limiting assembly 400 is also movable to avoid the swing unit 200 when the swing unit 200 swings between the first mounting position and the second mounting position.

[0040] As shown in Figure 3As shown, when cleaning a motor train with a small width, the swinging unit 200 can be swung to the first mounting position or the second mounting position to reduce the distance between the rolling brush 700 and the track 20, so as to prevent the motor train from being too small in the amount of body hair. After the rolling brush 700 is swung to the first mounting position or the second mounting position, the first limiting assembly 300 or the second limiting assembly 400 can limit the circumferential position of the swinging unit 200, so as to prevent the swinging unit 200 from swinging due to the friction of the motor train when the motor train runs along the track 20, so that the cleaning position of the rolling brush 700 remains unchanged, thereby ensuring that the amount of body hair of the motor train is constant. As shown in Figure 4 As shown, when cleaning a motor train with a large width, the swinging unit 200 is rotated to rotate the rolling brush 700 from the first mounting position to the second mounting position or from the second mounting position to the first mounting position, so as to increase the distance between the rolling brush 700 and the track 20, so as to prevent the motor train from being too large in the amount of body hair. After the rolling brush 700 is swung to the second mounting position or the first mounting position, the second limiting assembly 400 or the first limiting assembly 300 can limit the circumferential position of the swinging unit 200, so as to prevent the swinging unit 200 from swinging due to the friction of the motor train when the motor train runs along the track 20, so that the cleaning position of the rolling brush 700 remains unchanged, thereby ensuring that the amount of body hair of the motor train is constant. When the rolling brush 700 is rotated from the first mounting position to the second mounting position or from the second mounting position to the first mounting position, the second limiting assembly 400 can be moved to avoid the swinging unit 200, so that the swinging unit 200 can be smoothly swung between the first mounting position and the second mounting position, and the cleaning position of the rolling brush 700 can be adjusted.

[0041] It can be seen that the brush group mechanism 10 provided in the embodiment can position the swinging unit 200 at the first mounting position or the second mounting position according to the width of the motor train to be cleaned, so as to correspondingly adjust the amount of body hair of the motor train, so that the amount of body hair of the motor train is within a constant range when cleaning motor trains with different widths, so as to prevent the amount of body hair of the motor train from being too large or too small, and the cleaning efficiency of the motor train can be improved. Moreover, the brush group mechanism 10 also has the characteristics of simple structure, stable performance and easy maintenance.

[0042] In some embodiments of the present application, as shown in Figure 2 and Figure 3 As shown, the first limiting assembly 300 includes a first limiting piece, and the first limiting piece can be rotated on the mounting unit 100 with the rotating shaft of the swinging unit 200 as the center. In this way, the position of the first mounting position on the mounting unit 100 can be adjusted, the wear of the bristle length of the rolling brush 700 can be compensated, and of course the range of the width of the motor train that can be effectively cleaned can be further expanded, and the motor train with a larger or smaller width can be effectively cleaned.

[0043] In an embodiment, as shown in Figure 2 and Figure 4As shown, one of the first limiting member and the mounting unit 100 is provided with a first guide groove 100a, and the other is provided with a first guide block capable of moving in the first guide groove 100a. Through the cooperation of the first guide block and the first guide groove 100a, the swing unit 200 can be oriented to swing, facilitating the adjustment of the first mounting position. For example, the first guide groove 100a is arranged on the base 110 of the mounting unit 100, and the first guide block is arranged on the first limiting member; for another example, the first guide block is arranged on the base 110 of the mounting unit 100, and the first guide groove 100a is arranged on the first limiting member. It should be noted that, in order to clearly show the structure of the first guide groove 100a, Figure 3 the first limiting member is not shown in the figure.

[0044] Optionally, the first guide block can be a threaded part, such as a screw, which can be fixed at any position of the first guide groove 100a through the cooperation of a nut.

[0045] In an embodiment, the first limiting assembly 300 or the mounting unit 100 is provided with a first buffer 510, and the first limiting assembly 300 or the mounting unit 100 can abut against the first buffer 510 when the swing unit 200 swings to the first mounting position. The first buffer 510 can buffer the collision between the first limiting member and the mounting unit 100, and protect the first limiting member and the mounting unit 100. For example, as shown in the figure, Figure 3 the first buffer 510 is arranged on the swing arm 210 at the lower side of the mounting unit 100, and the first limiting assembly 300 can abut against the first buffer 510; for another example, the first buffer 510 is arranged on the first limiting assembly 300, and the mounting unit 100 can abut against the first buffer 510.

[0046] Optionally, the first buffer 510 can include a rubber pad, which can be fixed on the swing arm 210 at the lower side of the mounting unit 100 or the first limiting assembly 300 by screwing, bonding or other methods.

[0047] Since the base 110 and the swing arm 210 at the lower side of the mounting unit 100 have a height difference, as shown in the figure, Figure 2 the first limiting member includes a base 310 and a height increasing cylinder 320 arranged on the base 110, and the height increasing cylinder 320 can abut against the first buffer 510 at the first mounting position. Optionally, one side of the first buffer 510 facing the height increasing cylinder 320 is provided with a groove capable of accommodating the height increasing cylinder 320. The shape of the groove can be set according to the outer contour of the height increasing cylinder 320, for example, as shown in the figure, Figure 3 if the height increasing cylinder 320 is in a cylindrical structure, the groove is an arc-shaped groove; for another example, if the height increasing cylinder 320 is in a square tube structure, the groove is a square groove.

[0048] AsFigure 2 to Figure 4 As shown, in some embodiments of the present application, the second limiting assembly 400 includes a second limiting member 410 and a power member 420. The second limiting member 410 is rotatably mounted on the mounting unit 100 to abut or avoid the swing unit 200. The power member 420 can drive the second limiting member 410 to rotate. When the width of the motor vehicle to be cleaned is too large or too small, the power member of the mounting unit 100 drives the swing unit 200 to swing from the first mounting position to the second mounting position. The power member 420 also drives the second limiting member 410 to rotate, causing the second limiting member 410 to abut against the swing unit 200 in the second mounting position. When the width of the motor vehicle to be cleaned is too small or too large, the power member 420 drives the second limiting member 410 to rotate to reset the second limiting member 410, thereby avoiding the swinging of the swing unit 200. The power member of the mounting unit 100 then drives the swing unit 200 to swing from the second mounting position to the first mounting position. The entire adjustment process does not require human intervention, which can improve the automation level of the entire device.

[0049] In one embodiment, if Figure 2 As shown, the power member 420 includes a power cylinder, a cylinder body 421 of the power cylinder is connected to the mounting unit 100, and a piston rod 422 of the power cylinder is rotatably connected to the second stopper 410. When the piston rod 422 of the power cylinder is extended, the second stopper 410 can abut against the swing unit 200 in the second mounting position; when the piston rod 422 of the power cylinder is retracted, the second stopper 410 can avoid the swing unit 200.

[0050] The power cylinder can be a pneumatic cylinder or a hydraulic cylinder. Figure 2 As shown, the cylinder body 421 of the power cylinder can be fixed on the column 120 of the installation unit 100 using the first mounting bracket 610. As an example, Figure 2 As shown, the first mounting frame 610 is provided with two first ear plates 611 spaced apart from each other, and the cylinder body 421 of the power cylinder can be arranged between the first ear plates 611 by screw connection, clamping connection or the like.

[0051] like Figure 2 As shown, the second limiting member 410 includes a connected rotating plate 411 and a positioning cylinder 412. The rotating plate 411 is rotatably mounted on the base 110 of the mounting unit 100 via the second mounting bracket 620. The rotating plate 411 is also rotatably connected to the piston rod 422 of the power cylinder. The positioning cylinder 412 can abut against or avoid the swing unit 200. The rotating plate 411 can be configured as a triangular plate, a rectangular plate, or other structures, without specific limitation. As an example, Figure 2 As shown, the second mounting frame 620 is provided with two second ear plates 621 spaced apart from each other, and the rotating plate 411 is provided between the two second ear plates 621 and connected to the two second ear plates 621 through a rotating shaft.

[0052] In an embodiment, as shown in Figure 2 to Figure 4 The second limiting component 400 further comprises a stopper 430 arranged on the mounting unit 100, which can abut against the second limiting part 410 when the swinging unit 200 swings to the second mounting position, so as to limit the angle of the swinging unit 200 swinging from the second mounting position to the first mounting position. When the train runs along the track 20, the swinging unit 200 will swing due to the friction of the train. If the swinging force is too large, it will press the piston rod 422 of the power cylinder to retract, so that the second limiting component 400 cannot limit the swinging unit 200 in the circumferential direction at the second mounting position. Therefore, the stopper 430 is arranged on the base 110 of the mounting unit 100 to block the piston rod 422 of the power cylinder from retracting due to the pressure of the swinging unit 200.

[0053] As shown in Figure 2 The stopper 430 can comprise a bottom plate 431, a support rod 432 and a stopper block 433. The bottom plate 431 is arranged on the base 110 of the mounting unit 100, and the support rod 432 is used to support the stopper block 433 above the bottom plate 431. The number of stopper blocks 433 can be set according to the height of the positioning cylinder 412 of the second limiting part 410, as long as the second limiting part 410 can be effectively blocked. For example, as shown in Figure 2 The stopper blocks 433 are arranged in two on the support rod 432 in the up-down direction.

[0054] Alternatively, the stopper 430 can move on the mounting unit 100 to adjust the position of the second mounting position relative to the first mounting position. In this way, the position of the second mounting position on the mounting unit 100 can be adjusted, which can compensate for the wear of the bristle length of the rolling brush 700, and can further expand the range of train width that can be effectively cleaned, so that trains with larger or smaller widths can be effectively cleaned.

[0055] In an embodiment, as shown in Figure 2 One of the stopper 430 and the mounting unit 100 is provided with a second guide groove 100b, and the other is provided with a second guide block which can move in the second guide groove 100b. Through the cooperation of the second guide block and the second guide groove 100b, the stopper 430 can move in a certain direction, which is convenient for adjusting the second mounting position. For example, as shown in Figure 2 The second guide groove 100b is arranged on the base 110 of the mounting unit 100, and the second guide block is arranged on the bottom plate 431 of the stopper 430. Again, for example, the first guide block is arranged on the base 110 of the mounting unit 100, and the first guide groove 100a is arranged on the bottom plate 431 of the stopper 430.

[0056] Optionally, the second guide block can be a threaded member, such as a screw, which can be fixed at any position of the second guide groove 100b by cooperation of a nut.

[0057] In an embodiment, as shown in FIG. 1, the mounting unit 100 or the second limiting assembly 400 is provided with a second buffer 520, and the second limiting assembly 400 or the mounting unit 100 can abut against the second buffer 520 when the swinging unit 200 swings to the second mounting position. The second buffer 520 can buffer the collision between the second limiting member 410 and the mounting unit 100, and protect the second limiting member 410 and the mounting unit 100. For example, as shown in FIG. 1, the swinging arm 210 on the lower side of the mounting unit 100 is provided with the second buffer 520, and the second limiting assembly 400 can abut against the second buffer 520. For another example, the second limiting assembly 400 is provided with the second buffer 520, and the mounting unit 100 can abut against the second buffer 520. Figure 4 Figure 4 The second buffer 520 can buffer the collision between the second limiting member 410 and the mounting unit 100, and protect the second limiting member 410 and the mounting unit 100. For example, as shown in FIG. 1, the swinging arm 210 on the lower side of the mounting unit 100 is provided with the second buffer 520, and the second limiting assembly 400 can abut against the second buffer 520. For another example, the second limiting assembly 400 is provided with the second buffer 520, and the mounting unit 100 can abut against the second buffer 520.

[0058] Optionally, the second buffer 520 can include a rubber pad, which can be fixed on the swinging arm 210 on the lower side of the mounting unit 100 or the second limiting assembly 400 by screwing, bonding or the like.

[0059] On the other hand, an embodiment of the present application further provides a cleaning system, which includes the brush group mechanism 10 according to any one of the above embodiments. The vehicle cleaning system can be used to clean vehicles, such as rail transit vehicles, such as high-speed trains, bullet trains, trains, subways, etc., or other vehicles.
