A plurality of cleaning shells 402 are welded on the two first rotating shafts 401 at equal intervals. The upper part of the cleaning shell 402 is set in an inclined shape and is equipped with a blade. The inclined direction of the cleaning shell 402 is opposite to the moving direction of the step plate 1, and is used to clean the garbage and impurities in the groove of the step plate 1. The blade on the upper part of the cleaning shell 402 cuts the impurities that are difficult to clean, so that the garbage that is difficult to clean is separated from the step plate 1, and the cleaning The cleaning shell 402 slides in the groove of the step plate 1 respectively, and the cleaning shell 402 scrapes and cleans the garbage stuck in the groove of the step plate 1. The front and rear ends of the two first rotating shafts 401 are respectively fixed with first gears 403. The support plate 2 is bolted with four fixed guide rails 404.

The four racks 405 are respectively engaged with the adjacent first gears 403. The four racks 405 drive the adjacent first gears 403 to rotate. When the first rotating shafts 401 are used, the two first rotating shafts 401 drive the parts thereon to swing respectively. A second rotating shaft 406 is arranged between the two first rotating shafts 401. The second rotating shaft 406 is rotatably connected to the support plate 2 through a mounting seat. First connecting plates 407 are arranged at both ends of the second rotating shaft 406. The two first connecting plates 407 are each provided with two sliding grooves. The four racks 405 are respectively slidably connected to the sliding grooves of the adjacent first connecting plates 407 through sliding blocks. When the first connecting plate 407 swings, the racks 405 on the left and right sides move in opposite directions, so that the left and right sides are opposite to each other. The first rotating shafts 401 on the right side rotate in opposite directions, the second rotating shaft 406 is keyed to a second gear 408, the support plate 2 is bolted to a stepper motor 409, the stepper motor 409 is electrically connected to the monitoring module 303, the stepper motor 409 has a self-locking function, the stepper motor 409 changes the direction of the output shaft so that the two first rotating shafts 401 and the cleaning shell 402 thereon clean the step plate 1 alternately, the output shaft of the stepper motor 409 is keyed to a third gear 410, and the second gear 408 is meshed with the third gear 410.

[0032] like Figure 7As shown, the tooth plate cleaning mechanism includes two fixed frames 501, the two fixed frames 501 are respectively fixed to the cleaning shells 402 of the front and rear parts, the middle parts of the two fixed frames 501 are provided with long through holes, the long through holes of the two fixed frames 501 are bolted with fixed rods 502, the front and rear cleaning shells 402 are welded with second connecting plates 503, the two second connecting plates 503 are respectively slidably connected to the long through holes of adjacent fixed frames 501 through sliding blocks, the two fixing rods 502 respectively pass through the adjacent second connecting plates 503 and are slidably connected thereto, the two fixing rods 502 are both sleeved with first springs 504, and the first springs 5 The two ends of 04 are respectively fixed to the adjacent fixed frames 501 and the second connecting plate 503, and the scrapers 505 for cleaning the tooth plates of the step plates 1 are welded on the two fixed frames 501. When the cleaning shell 402 contacts the groove of the step plates 1, the scrapers 505 are squeezed onto the tooth plates of the step plates 1 under the elastic force of the first spring 504, and a wedge-shaped blade is bolted to one side of the scraper 505. The wedge-shaped blade of the scraper 505 cleans the impurities adhered to the tooth plates of the step plates 1 to improve the cleaning effect of the scraper 505. The wedge-shaped blade of the scraper 505 slides with the lower side of the tooth plates of the step plates 1 to clean the impurities adhered to the tooth plates of the step plates 1.

[0033] like Figure 8 As shown, two collecting shells 601 are connected to the support plate 2 through mounting seat bolts, and the two collecting shells 601 are respectively located at the lower sides of the two first rotating shafts 401, and are used to collect garbage and impurities in the groove of the step plate 1. A number of elastic sheets 602 are welded at equal intervals on the two collecting shells 601, and the upper ends of the elastic sheets 602 are bolted with cleaning blades. When the cleaning shells 402 swing downward, the elastic sheets 602 clean the garbage and impurities adhered to the adjacent cleaning shells 402, thereby improving the practicality of the device. The upper ends of each elastic sheet 602 are respectively slidably matched with the inner side surfaces of the adjacent cleaning shells 402, and the elastic sheets 602 are used to clean the garbage and impurities adhered to the cleaning shells 402.

[0034] like Fig. 9 and Fig.10As shown, the adhesive cleaning mechanism includes two second fixed plates 701, which are respectively welded to the front and rear parts of the first rotating shaft 401, and the two second fixed plates 701 are respectively connected to the first extrusion wheel 702 through the rotating shaft. The counterclockwise swing of the first rotating shaft 401 will drive the second fixed plate 701 and the first extrusion wheel 702 thereon to swing counterclockwise, and the first extrusion wheel 702 is squeezed on the lower side of the step plate 1, and the step plate 1 drives the first extrusion wheel 702 to rotate. A winding roller 703 is welded to the rotating shaft of the first extrusion wheel 702, and one side of the first rotating shaft 401 is bolted to two support seats 704, and the two support seats 704 are bolted to guide rings 705, and connecting rods 706 are welded to the two support seats 704. The connecting rod 706 is slidably connected to two sliding plates 707, and the two sliding plates 707 are respectively connected to the winding roller 703 on the same side through a connecting rope. The first extrusion wheel 702 drives the winding roller 703 to rotate through the rotating shaft and winds up the connecting rope thereon. The two connecting ropes pass through the guide ring 705 on the same side. The front and rear parts of the connecting rod 706 are respectively ringed with second springs 708. The two connecting ropes pull the sliding plates 707 on the same side to both sides, and the two second springs 708 are compressed. When the first extrusion wheel 702 loses contact with the step plate 1, the two sliding plates 707 are close to the sliding cleaning scraper 505 under the elastic force of the two second springs 708, and the two ends of the two second springs 708 are respectively fixed to the adjacent support seat 704 and the sliding plates 707.

[0035] The staff installed the device on the lower side of the step plate 1, and the device was fixed on the supporting frame of the escalator, so that several swing blocks 304 were placed in the adjacent grooves of the step plate 1 respectively. After the swing blocks 304 were squeezed, the torsion springs 305 were tightened, and then the staff started the escalator. After the escalator started, the step plates 1 rotated in a circle in sequence, and the swing blocks 304 slid in the grooves of the step plates 1. Long-term use of the escalator will cause broken teeth and cavities at the connection of the step plates 1. The step plates 1 are driven in sequence. When the broken teeth and cavities at the connection of the step plates 1 move to the upper side of the swing blocks 304, the swing blocks 304 lose the squeezing of the step plates 1, and the torsion of the torsion springs 305 causes the swing blocks 304 to swing clockwise, and the lower end of the swing blocks 304 contacts the electrode plate 301, so that the swing blocks 304, the electrode plate 301 and the power supply unit in the monitoring module 303 are The monitoring module 303 detects that there is current in the path, and the monitoring module 303 transmits the monitoring data to the remote signal receiving terminal through the Internet of Things. When the broken tooth hole at the connection of the step plate 1 is away from the swing block 304, the step plate 1 squeezes the swing block 304 again, and the torsion spring 305 is tightened. If two or more broken tooth holes appear at the connection of the step plate 1, multiple swing blocks 304 swing at the same time, and the monitoring module 303 monitors the magnitude of the current and transmits the real-time data to the remote signal receiving terminal. The staff knows that the escalator has broken tooth holes according to the signal received by the remote signal receiving terminal. The staff can repair and maintain the escalator in time, which improves the safety of the escalator and avoids the high heels of the passengers or the fingers of children and other body parts getting stuck in the broken tooth holes at the connection of the step plate 1 during the operation of the escalator.

[0036] When the step plate 1 of the escalator rotates circumferentially in sequence, the monitoring module 303 intermittently starts the stepper motor 409, and the output shaft of the stepper motor 409 is transmitted through the second gear 408 and the third gear 410. The second gear 408 drives the two first connecting plates 407 to swing counterclockwise, and the two first connecting plates 407 drive the two racks 405 on the left to move downward and the two racks 405 on the right to move upward. The four racks 405 are used to drive the adjacent first gears 403 to rotate, so that the first rotating shaft 401 on the left rotates counterclockwise, and the first rotating shaft 401 on the left drives the cleaning shell 402 thereon to swing counterclockwise and cooperate with the groove of the step plate 1. The first rotating shaft 401 on the side drives the cleaning shell 402 thereon to swing clockwise, and the cleaning shell 402 on the right side moves away from the step plate 1. When the step plate 1 moves to the left, the cleaning shell 402 scrapes and cleans the garbage adhered in the groove of the step plate 1, so as to prevent the garbage in the step plate 1 from affecting the normal operation of the escalator, thereby reducing the labor intensity of manual cleaning. When the cleaning shell 402 on the left side swings counterclockwise, it drives the two fixed frames 501 thereon to swing counterclockwise, so that the scraper 505 contacts the tooth plate of the step plate 1, and the cleaning shell 402 on the left side continues to swing into the groove of the step plate 1, and the cleaning shell 402 on the left side drives the two second connecting plates 503 thereon. The two first springs 504 on the left are compressed, and the elastic force of the two first springs 504 provides an extrusion force on the scraper 505 on the left. When the step plate 1 moves to the left, the lower side of the tooth plate of the step plate 1 cooperates with the scraper 505 on the left. The scraper 505 on the left scrapes and cleans the garbage and impurities adhered to the lower side of the tooth plate of the step plate 1, thereby reducing the labor intensity of manual cleaning of the escalator and preventing the garbage adhered to the step plate 1 from accumulating on the comb plate of the escalator, affecting the normal operation of the escalator. After working for a period of time, the monitoring module 303 starts the stepping motor 409 to rotate its output shaft clockwise, and the second The moving shaft 406 drives the first connecting plate 407 to swing clockwise, and the cleaning shell 402 on the left side swings clockwise away from the groove of the step plate 1, and the cleaning shell 402 on the left side drives the scraper 505 away from the lower side of the tooth plate of the step plate 1. The cleaning shell 402 on the right side swings counterclockwise to drive the scraper 505 thereon to contact the step plate 1, and clean the groove and the lower side of the tooth plate of the step plate 1. When the cleaning shell 402 is away from the step plate 1, it will pull down the garbage impurities stuck on the step plate 1. It is difficult to separate sticky garbage such as chewing gum from the step plate 1. By pulling the cleaning shell 402 downward, the cleaning effect of the garbage impurities stuck on the step plate 1 is improved.

[0037] When the cleaning shell 402 on the left side swings clockwise, the cleaning shell 402 on the left side will squeeze the elastic sheet 602 downward, and the elastic sheet 602 slides along the adjacent cleaning shell 402. The elastic sheet 602 scrapes off the garbage adhering to the adjacent cleaning shell 402, thereby improving the practicality of the device and avoiding the garbage impurities adhering to the cleaning shell 402 to reduce the cleaning effect of the groove of the step plate 1. The garbage cleaned from the step plate 1 falls into the collecting shell 601 for collection, and the staff cleans the garbage in the collecting shell 601 regularly.

[0038] The first rotating shaft 401 on the left drives the two second fixed plates 701 to swing counterclockwise, and the two second fixed plates 701 drive the first extrusion wheels 702 thereon to squeeze and contact the lower side of the step plate 1. At the same time, the scraper 505 on the left loses contact with the two adjacent sliding sheets 707. The two first extrusion wheels 702 respectively drive the adjacent winding rollers 703 to rotate, and the two winding rollers 703 wind up the connecting ropes connected thereto. The two connecting ropes respectively pull the sliding sheets 707 on the same side to slide away from each other along the connecting rod 706. At the same time, the two second springs 708 of the connecting rod 706 on the left are compressed. When the upper part swings clockwise to reset, the scraper 505 on the left quickly resets, and at the same time, the two first extrusion wheels 702 on the left lose contact with the step plate 1, and the two left sliding sheets 707 quickly reset under the elastic force of the two second springs 708, and the two left sliding sheets 707 slide along the adjacent scrapers 505 to clean the garbage and impurities adhered to the scrapers 505, thereby improving the practicality of the device and avoiding a large amount of garbage and impurities adhered to the scrapers 505 to reduce the cleaning effect of the step plate 1, and using the stepper motor 409 to make the first rotating shafts 401 on the left and right sides drive the parts thereon to swing, and continuously detect the step plate 1 of the escalator.

The first extrusion wheel 702 and the second extrusion wheel 801 are both configured as rubber wheels for increasing the friction with the step plate 1. The second extrusion wheel 801 is in extrusion contact with the step plate 1. A collection box 802 is fixedly connected to the support plate 2. The collection box 802 is rotatably connected to a cleaning roller 803. The cleaning roller 803 is provided with A hard brush is provided, and the hard brush of the cleaning roller 803 cleans the dust on the step plate 1, and the cleaned dust falls into the collection box 802, reducing the labor intensity of manual cleaning. The hard brush of the cleaning roller 803 squeezes the broken tooth part and cleans the dust on the step plate 1. The cleaning roller 803 and the rotating shaft of the second squeezing wheel 801 are driven by belts and pulleys. The hard brush of the cleaning roller 803 is used to squeeze the step plate 1 upward, so that the cracked broken teeth fall off the step plate 1 to form broken tooth cavities, and cooperates with the swing block 304 to monitor the broken tooth cavities, reminding the staff to repair and maintain the escalator in time.

[0041] As the step plate 1 rotates circumferentially in sequence, the step plate 1 drives the second extrusion wheel 801 to rotate, and the second extrusion wheel 801 drives the cleaning roller 803 to rotate through the belt and the pulley, and the hard brush of the cleaning roller 803 cleans the dust on the step plate 1, and the cleaned dust falls into the collection box 802, thereby improving the cleaning effect of the device on the step plate 1 and reducing the labor intensity of manual cleaning. When cracks appear at the connection between two adjacent step plates 1, broken teeth fall off and form holes under the action of external force. At this time, the hard brush of the cleaning roller 803 is used to squeeze the step plate 1, so that the cracked part of the step plate 1 is pressed upward. If the cracked broken teeth do not fall off, it will affect the subsequent monitoring of the broken tooth holes by the swing block 304, resulting in the failure to timely monitor the broken teeth of the escalator. At the same time, the passengers cannot observe the broken tooth holes, resulting in the heels of high heels being inserted into the broken tooth holes.
