[0056] Specifically, the expansion unit 500 includes a second transmission rod 501 rotatably disposed in the inner cavity of the fixed cover 301 , a transmission wheel 502 disposed on the outer wall of the second transmission rod 501 and the transmission rod 304 b , and a belt 503 sleeved on two adjacent transmission wheels 502 .

[0057] It should be noted that the expansion unit 500 includes a second transmission rod 501 rotatably connected to the inner cavity of the fixed cover 301, the bottom end of the second transmission rod 501 is fixedly connected to the corresponding cleaning wheel 303, a transmission wheel 502 is fixedly connected to the outer wall of the transmission rod 304b and the second transmission rod 501, and a belt 503 is sleeved on the outer wall of the transmission wheel 502. By setting the expansion unit 500, the number of cleaning wheels 303 can be increased, thereby increasing the cleaning area.

[0058] Specifically, the mobile unit 400 includes a mounting seat 401 disposed on both sides of the mounting plate 101, a wheel 402 rotatably disposed in the inner cavity of the mounting seat 401, a gear 403 disposed on the rotating shaft of the wheel 402, a transmission chain 404 disposed on the gear 403, a mobile motor 405 disposed inside the mounting seat 401; and a track 406 disposed below the wheel 402;

[0059] The output end of the moving motor 405 is connected to the rotating shaft of one set of wheels 402 .

[0060] It should be noted that the mobile unit 400 includes a mounting base 401 fixedly installed on both sides of the mounting plate 101, and a wheel 402 rotatably installed in the inner cavity of the mounting base 401. A mobile motor 405 is fixedly connected to one side of the mounting base 401, and the output end of the mobile motor 405 is fixedly connected to the rotating shaft of one set of wheels 402. One end of the rotating shaft of the wheel 402 is fixedly connected to a gear 403, and the outer wall of the gear 403 is sleeved with a transmission chain 404, and the wheel 402 rolls in a track 406, and the track 406 is fixedly installed in the station.

[0061] When in use, one set of wheels 402 is driven to rotate by the mobile motor 405, and when the wheels 402 rotate, the transmission chain 404 drives multiple gears 403 to rotate, and the gears 403 drive the remaining wheels 402 to rotate, and the wheels 402 roll in the track 406 to achieve linear movement of the device;

[0062] The cleaning motor 302 rotates to drive the rotating rod 304a to rotate, and the rotating rod 304a drives the transmission gear 304d to rotate. The transmission gear 304d drives the outer driven gear 304c to rotate. When the driven gear 304c rotates, it drives the transmission rod 304b to rotate. While the transmission rod 304b drives the cleaning wheel 303 at the bottom to rotate, it drives the second transmission rod 501 to rotate through the belt 503. The second transmission rod 501 drives the cleaning wheel 303 at the bottom to rotate, thereby realizing the rotation of all the cleaning wheels 303, and then the cleaning wheels 303 are driven to move in the car through the lifting unit 200 and the moving unit 400 to achieve cleaning.

[0063] In summary, by rotating the cleaning wheel 303 and driving the cleaning wheel 303 to move in the carriage through the moving unit 400 and the lifting unit 200, the interior of the carriage can be fully cleaned, which solves the problem of dust being raised during manual cleaning, which poses a safety threat to the cleaning staff's lungs when they inhale dust, and the extremely low efficiency of manual cleaning.

[0064] Example 3

[0065] Reference Figure 1 - Figure 6 The third embodiment of the present invention further provides a lifting unit 200 based on the first embodiment, including a slide rail 201 arranged on the inner wall of the mounting plate 101, a lifting motor 202 arranged on the top of the slide rail 201, a slider 203 slidably arranged on the inner wall of the slide rail 201, a threaded rod 204 threadedly arranged on the inner wall of the slider 203, and a mounting frame 205 arranged between two adjacent sliders;

[0066] The threaded rod 204 is rotatably connected to the inner cavity of the slide rail 201 , and the threaded rod 204 is fixedly connected to the top end and the output end of the lifting motor 202 .

[0067] It should be noted that the lifting unit 200 includes a slide rail 201 fixedly welded to the inner side of the mounting plate 101, a slider 203 is slidably connected to the inner wall of the slide rail 201, a threaded rod 204 is also rotatably connected inside the slide rail 201, and the threaded rod 204 and the slider 203 are threadedly connected, a lifting motor 202 is fixedly connected to the top of the slide rail 201, the output end of the lifting motor 202 is fixedly connected to the threaded rod 204, and the two ends of the mounting frame 205 and the inner sides of the two sliders 203 are fixedly welded.

[0068] When in use, the lifting motor 202 is started, and the lifting motor 202 drives the threaded rod 204 to rotate. Since the threaded rod 204 and the slider 203 are threadedly connected, the threaded rod 204 can drive the slider 203 to slide in the slide rail 201 when it rotates, thereby driving the mounting frame 205 to rise and fall.

[0069] In summary, the threaded rod 204 is rotated to drive the mounting frame 205 to achieve lifting and lowering. The mounting frame 205 is the movable end of the lifting unit 200. The mounting frame 205 drives the cleaning unit 300 to extend into the compartment to achieve cleaning, and the threaded rod 204 is placed vertically to meet the lifting of large weights.

[0070] Example 4

[0071] Reference Figure 1 - Figure 6, which is a fourth embodiment of the present invention based on the first embodiment, includes a lifting unit 200 including a limiting column arranged on the inner wall of the mounting plate 101, a lifting block slidably arranged on the limiting column, a reciprocating motor arranged at both ends of the limiting column, a transmission wheel arranged at the output end of the reciprocating motor, a transmission belt sleeved on the transmission wheel, and a second mounting frame arranged between two adjacent lifting blocks;

[0072] One side of the transmission belt is fixedly connected to one side of the lifting block.

[0073] It should be noted that the lifting unit includes a limiting column fixedly welded to the inner wall of the mounting plate 101, a lifting block is slidably connected to the outer wall of the limiting column, a reciprocating motor is fixedly connected to both ends of the limiting column, a transmission wheel is fixedly connected to the output end of the reciprocating motor, a transmission belt is sleeved on the two transmission wheels, and one side of the transmission belt is fixedly connected to one side of the lifting block, and a second mounting frame is fixedly welded to the inner side of the two lifting blocks.

[0074] When in use, the reciprocating motor is started, and the reciprocating motor drives the transmission wheel to rotate, thereby driving the transmission belt to move on the transmission wheel. When the transmission belt moves, it drives the lifting block to move, thereby driving the second mounting frame to lift.

[0075] In summary, the lifting block is driven to move by the transmission belt, which in turn drives the second mounting frame to be lifted and lowered. The second mounting frame is the moving end of the lifting unit 200. The second mounting frame drives the lower cleaning unit 300 to extend into the compartment for cleaning. Because the transmission belt needs to bear the weight of the cleaning unit 300, compared with the second embodiment, the weight that the transmission belt can bear is less than the weight that the threaded rod 204 can bear. Therefore, the second embodiment is the preferred solution of the present invention.

[0076] A method for using a carriage cleaning machine comprises the following steps:

[0077] S1. After the coal unloading of the carriage is completed, the moving unit 400 is started to move the installation unit 100 to the top of the unloading carriage;

[0080] S4. Start the moving unit 400 and the lifting unit 200 again to drive the cleaning wheel 303 to fully clean the interior of the carriage.

[0081] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
