[0048] Please refer to Figures 1 to 5 The present invention provides a cleaning mechanism for cleaning residual materials in a train carriage, comprising a frame 1, and a front disc brush assembly 2, a rear disc brush assembly 3, a front material suction assembly 4 and a rear material suction assembly 5 arranged on the frame 1; the front disc brush assembly 2 is arranged on the front side of the frame 1; the rear disc brush assembly 3 is arranged on the rear side of the frame 1;

[0049] The front suction assembly 4 includes a front lifting assembly 41 and a first suction assembly 42, wherein the front lifting assembly 41 is arranged at the front side of the rear disc brush assembly 3, and the driving end of the front lifting assembly 41 is connected to the first suction assembly 42; the rear suction assembly 5 includes a rear lifting assembly 51 and a second suction assembly 52, wherein the rear lifting assembly 51 is arranged at the rear side of the front disc brush assembly 2, and the driving end of the rear lifting assembly 51 is connected to the second suction assembly 52;

[0050] The state of the cleaning mechanism for cleaning residual materials in the train carriage includes a forward cleaning state and a backward cleaning state; when the cleaning mechanism for cleaning residual materials in the train carriage is in the forward cleaning state, the driving end of the rear lifting assembly 51 drives the second material suction assembly 52 to be lifted, so that the second material suction assembly 52 is close to the frame 1, and the driving end of the front lifting assembly 41 drives the first material suction assembly 42 to be lowered, so that the first material suction assembly 42 is away from the frame 1;

[0051] When the cleaning mechanism for cleaning residual materials in the train carriage is in a forward cleaning state, the driving end of the front lifting assembly 41 drives the first suction assembly 42 to rise, so that the first suction assembly 42 is close to the frame 1, and the driving end of the rear lifting assembly 51 drives the second suction assembly 52 to descend, so that the second suction assembly 52 is away from the frame 1.

[0052] The cleaning mechanism for cleaning residual materials in the train carriage is provided with a front disc brush assembly 2, a rear disc brush assembly 3, a front suction assembly 4 and a rear suction assembly 5. The cleaning mechanism for cleaning residual materials in the train carriage includes two modes: a forward cleaning state and a backward cleaning state.

[0053] When the cleaning mechanism is in the forward cleaning state, the rear lifting assembly 51 controls the second suction assembly 52 to retract into the frame 1, and the front lifting assembly 41 controls the first suction assembly 42 to extend from the frame 1 and approach the bottom of the compartment; subsequently, the cleaning mechanism is driven forward by an external driving device, and the front disc brush assembly 2 and the rear disc brush assembly 3 clean the bottom and side walls of the compartment, while the first suction assembly 42 removes the residual materials in the compartment collected during the forward movement; when the cleaning mechanism is in the backward cleaning state, the front lifting assembly 41 controls the first suction assembly 42 to retract into the frame 1, and the rear lifting assembly 51 controls the second suction assembly 52 to extend from the frame 1 and approach the bottom of the compartment; subsequently, the cleaning mechanism is driven backward by an external driving device, and the front disc brush assembly 2 and the rear disc brush assembly 3 clean the bottom and side walls of the compartment again, while the second suction assembly 52 removes the residual materials in the compartment collected during the backward movement.

[0054] By adopting the above structure, the cleaning mechanism for cleaning residual materials in the train carriage can be directly installed on the mobile device, eliminating the slewing support structure and without the need to rely on the slewing support structure for reversing. Cleaning in both the forward and backward directions can be achieved directly through the cooperation of the front disc brush assembly 2, the rear disc brush assembly 3, the front suction assembly 4 and the rear suction assembly 5. The layout of the oil circuit and the wires of the cleaning mechanism is simpler, which is convenient for subsequent maintenance and operation. Moreover, the structure is simpler, the operation process is smoother, and the stability and cleaning effect of the cleaning mechanism are improved.

[0055] The frame 1 is used to fix the front disc brush assembly 2, the rear disc brush assembly 3, the front suction assembly 4 and the rear suction assembly 5, and is connected to an external driving device so that the cleaning mechanism can move forward or backward.

[0056] The front suction assembly 4 and the rear suction assembly 5 are connected to an external negative pressure device, and the negative pressure generated by the external negative pressure device sucks away the residual material. The front disc brush assembly 2 and the rear disc brush assembly 3 are used to clean the bottom and side walls of the carriage, so that the residual material attached to the bottom and side walls of the carriage can be separated to avoid residual material residue; then, the front suction assembly 4 or the rear suction assembly 5 sucks away the residual material.

[0057] Preferably, it further comprises a middle plate brush assembly 6, which is disposed between the front suction assembly 4 and the rear suction assembly 5, and comprises a first middle plate brush 61, a first angle adjustment assembly, a first column 62, a second middle plate brush, a second angle adjustment assembly and a second column;

[0058] The first column 62 and the second column are arranged side by side on the frame 1; the first angle adjustment component is arranged on the first column 62, the first middle disc brush 61 can be swingably installed on the first column 62, and the driving end of the first angle adjustment component is drivingly connected to the first middle disc brush 61, and is used to adjust the angle of the first middle disc brush 61 so that the first middle disc brush 61 can swing in the front-back direction;

[0059] The second angle adjustment component is arranged on the second column, and the second middle disc brush can be swingably installed on the second column. The driving end of the second angle adjustment component is drivingly connected to the second middle disc brush for adjusting the angle of the second middle disc brush so that the second middle disc brush can swing in the front and rear directions.

[0060] The first middle disc brush 61 and the second middle disc brush are used to clean the bottom and side walls of the compartment, and assist the front disc brush assembly 2 and the rear disc brush assembly 3 in cleaning, so as to further enhance the cleaning effect and avoid residual materials remaining in the compartment.

[0061] The first column 62 is used to connect the first center plate brush 61 and the first angle adjustment assembly to the frame 1 , and the second column is used to connect the second center plate brush and the second angle adjustment assembly to the frame 1 .

[0062] The first angle adjustment assembly is used to adjust the angle of the first center brush 61, thereby changing the direction of the first center brush 61, and the second angle adjustment assembly is used to adjust the angle of the second center brush, thereby changing the direction of the second center brush; through the first angle adjustment assembly and the second angle adjustment assembly, the direction of the first center brush 61 and the second center brush can be adjusted according to the state of the cleaning mechanism for cleaning residual materials in the train carriage. When the cleaning mechanism is in the forward cleaning state, the first center brush 61 and the second center brush can be directed to the front side. When the cleaning mechanism is in the backward cleaning state, the first center brush 61 and the second center brush can be directed to the rear side.

[0063] By adopting the above structure, the first center disc brush 61 and the second center disc brush can change the direction according to the state of the cleaning mechanism for cleaning residual materials in the train carriage, thereby improving the cleaning effect of the first center disc brush 61 and the second center disc brush, and can better adapt to the situation where the carriage wall is uneven or the welding size error of the carriage rib plate is large.

[0087] The rotating driving member 222 is electrically connected to the external control system, and is used to drive the cleaning head body 221 to rotate. The cleaning head mounting seat 223 is used to mount the cleaning head body 221 and the rotating driving member 222, so that the cleaning head body 221 and the rotating driving member 222 can swing in the left and right directions, and is also used to connect with the cleaning head adjustment driving member 225 to achieve the effect of adjusting the direction of the cleaning head body 221. The driving member fixing seat 224 is used to fix the cleaning head adjustment driving member 225. The above structure can better adapt to the situation where the car wall is uneven or the welding size error of the car rib plate is large, and enhance the cleaning effect.

[0088] Specifically, the structure of the first suction assembly 42 is the same as that of the second suction assembly 52, including a collecting cover assembly and a suction pipe 401; the collecting cover assembly is connected to the frame 1 through the front lifting assembly 41 or the rear lifting assembly 51, one end of the suction pipe 401 is connected to the collecting cover assembly, and the other end of the suction pipe 401 is connected to an external negative pressure device; the collecting cover assembly is used to collect the residual material at the connection point between the suction pipe 401 and the collecting cover assembly.

[0089] The first suction assembly 42 and the second suction assembly 52 have the same structure, and the difference lies in the installation direction and the direction of collecting residual materials.

[0090] One end of the suction pipe 401 is connected to the collection cover assembly, and the other end of the suction pipe 401 is connected to the external negative pressure device.

[0095] The external driving device cooperates with the scraper 407 to limit the residual material that cannot be sucked away in time in the collection chamber 408, and prevent the residual material from flowing out from the gap between the collection cover body 402 and the bottom of the carriage. During the working process, the residual material enters the collection chamber 408 from the air-avoiding opening.

[0096] In practical applications, the shaft driving device 403 may be a motor or a hydraulic motor, and the shaft driving device 403 is connected to the shaft 404 through a chain to drive the shaft 404 to rotate, so that the first spiral roller brush 405 and the second spiral roller brush 406 rotate along with the shaft 404. Since the spiral directions of the first spiral roller brush 405 and the second spiral roller brush 406 are both toward the connection point between the suction pipe 401 and the collection cover assembly, when the shaft 404 rotates, the first spiral roller brush 405 and the second spiral roller brush 406 can guide the residual material in the collection chamber 408 to the entrance of the suction pipe 401, thereby achieving the effect of extracting the residual material and avoiding residual material residue.

[0097] Furthermore, the front lifting assembly 41 and the rear lifting assembly 51 have the same structure, including a lifting drive member 501, a drive mounting seat 502, a first guide rod 503, a second guide rod 504 and a connecting rod 505;

[0099] The first guide rod 503 and the second guide rod 504 play a guiding role, avoiding deviation or irregular movement during the movement, enhancing the stability during the lifting process, and making the movement process of the collection cover assembly more stable. The connecting rod 505 plays a limiting role, limiting the range of downward movement of the collection cover assembly, avoiding the collection cover assembly exceeding the predetermined operating range, causing damage or system failure.

[0100] The lifting drive member 501 can be a linear drive device such as a cylinder or an oil cylinder, and the collection cover assembly can be lowered or raised by extending or retracting the driving end of the lifting drive member 501. The drive mounting seat 502 is used to install the lifting drive member 501, and to install the first guide rod 503 and the second guide rod 504.

[0101] In a specific embodiment of the present invention, both left and right sides of the suction pipe 401 of the front suction assembly 4 are provided with front lifting assemblies 41, and both left and right sides of the suction pipe 401 of the rear suction assembly 5 are provided with rear lifting assemblies 51.
