[0022] Reference Figure 1-4 , an escalator step surface cleaning device, comprising a mounting frame 1, a fixing component 2 is installed inside the mounting frame 1, the fixing component 2 is used to fix the device on the side wall of the escalator, a cleaning component 3 is fixedly connected to the bottom of the mounting frame 1, the cleaning component 3 is used to clean the escalator surface, an elastic component 4 is fixedly connected between the cleaning component 3 and the mounting frame 1, and also includes:

[0023] The cleaning component 3 includes a connecting frame 301, which is fixedly mounted at the bottom end of the elastic component 4. The inner wall of the connecting frame 301 is rotatably connected to a sticky roller 302. The side wall of the connecting frame 301 is fixedly connected to a connecting plate 303. The side wall of the connecting plate 303 is fixedly connected to a scraper 304. The scraper 304 is in contact with the side wall of the sticky roller 302, and the scraper 304 is arranged in an inclined shape.

[0024] The elastic component 4 includes a sleeve 401, which is fixedly mounted on the bottom of the mounting frame 1. A sliding column 402 is slidably connected to the inner wall of the sleeve 401, and the sliding column 402 is fixedly connected to the connecting frame 301. A first spring 403 is fixedly connected between the sliding column 402 and the sleeve 401.

[0025] It should be noted that: first, the device is fixed to the side wall of the escalator using the fixing component 2, and then the elastic force of the first spring 403 in the elastic component 4 is used to make the sliding column 402 slide down in the sleeve 401, thereby driving the connecting frame 301 to slide down, so that the sticky roller 302 connected to the inside of the connecting frame 301 is in contact with the surface of the step, so that when the step moves, the sticky roller 302 can rotate on the surface of the step, thereby sticking impurities on the surface of the step to the surface of the sticky roller 302, and as the sticky roller 302 rotates, the scraper 304 on the side wall of the connecting plate 303 will remove the impurities on the surface of the sticky roller 302, which is simple and convenient.

[0026] Reference Figure 1-4 The fixing assembly 2 includes a sliding plate 201, which is slidably mounted on both sides of the inner wall of the mounting frame 1, and a support plate 202 is fixedly connected to the end of the sliding plate 201 located on the outer side of the mounting frame 1;

[0027] The side wall of the mounting frame 1 is rotatably connected with a rotating column 203, and the end of the rotating column 203 located in the inner cavity of the mounting frame 1 is fixedly connected with a rotating disk 204, and the rotating disk 204 and the sliding plate 201 are meshedly connected;

[0028] The side wall of the sliding plate 201 is fixedly connected with an inner tooth plate 205, and the side wall of the rotating disk 204 is provided with a tooth groove 206, and the inner tooth plate 205 is meshedly connected with the tooth groove 206 on the side wall of the rotating disk 204;

[0029] It should be noted that: the rotating column 203 on the side wall of the rotating mounting frame 1 is engaged with the tooth groove 206 on the side wall of the rotating column 203 and the inner tooth plate 205 on the side wall of the sliding plate 201. Therefore, when the rotating column 203 is rotated, the sliding plate 201 will simultaneously move away from the mounting frame 1, so that the support plate 202 at the end of the sliding plate 201 squeezes the side wall of the escalator, thereby fixing the mounting frame 1 on the inner wall of the escalator, which is convenient for subsequent cleaning of the escalator.

[0030] Reference Figure 1-4 A slot 5 is provided on the side wall of the rotating column 203 outside the mounting frame 1, a side plate 501 is fixedly connected to the side wall of the mounting frame 1, a post 502 is slidably connected to the side wall of the side plate 501, and the post 502 can extend to the inner cavity of the slot 5;

[0031] A second spring 503 is fixedly connected between the clamping column 502 and the side plate 501. The end of the clamping column 502 is rotatably connected to the limiting plate 504. The side wall of the side plate 501 is fixedly connected to the limiting column 505, and the limiting plate 504 can overlap the end of the limiting column 505.

[0032] It should be noted that: before fixing the mounting frame 1, the limit plate 504 is overlapped on the top of the limit column 505. At this time, the second spring 503 is compressed. After positioning the mounting frame 1, the limit plate 504 is rotated to make the limit plate 504 away from the limit column 505. At this time, under the action of the rebound force of the second spring 503, the clamping column 502 slides toward the rotating column 203 and extends to the inner cavity of the clamping groove 5 opened on the side wall of the rotating column 203, completing the fixation of the rotating column 203, thereby ensuring that during the subsequent cleaning process, the rotating column 203 will not rotate and affect the fixation of the mounting frame 1.

[0033] Operation method: Rotate the rotating column 203 of the side wall of the mounting frame 1. Since the tooth groove 206 of the side wall of the rotating column 203 is meshed and connected with the inner tooth plate 205 of the side wall of the sliding plate 201, when the rotating column 203 is rotated, the sliding plate 201 will simultaneously move away from the mounting frame 1, so that the support plate 202 at the end of the sliding plate 201 squeezes the side wall of the escalator, thereby fixing the mounting frame 1 on the inner wall of the escalator. Before fixing the mounting frame 1, the limit plate 504 is overlapped on the top of the limit column 505. At this time, the second spring 503 is compressed. After positioning the mounting frame 1, the limit plate 504 is rotated to make the limit plate 504 move away from the limit column 505. At this time, under the action of the rebound force of the second spring 503, the clamping column 502 slides toward the rotating column 203 and extends to the inner cavity of the clamping groove 5 opened on the side wall of the rotating column 203, completing the fixing of the rotating column 203, thereby ensuring that in the subsequent cleaning process, the rotating column 203 will not rotate to affect the fixing of the mounting frame 1;

[0034] Then, the elastic force of the first spring 403 in the elastic component 4 is utilized to make the sliding column 402 slide down in the sleeve 401, thereby driving the connecting frame 301 to slide down, so that the sticking roller 302 connected and rotating inside the connecting frame 301 fits with the surface of the step, so that when the step moves, the sticking roller 302 can rotate on the surface of the step, so that impurities on the surface of the step are adhered to the surface of the sticking roller 302, and as the sticking roller 302 rotates, the scraper 304 on the side wall of the connecting plate 303 will remove the impurities on the surface of the sticking roller 302, which is simple and convenient.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
