Description

Technical Field

[0001] The present invention relates to the technical field of escalator cleaning, and particularly to an escalator with a step cleaning and disinfection function. Background Art

[0002] An escalator consists of a ladder road and handrails on both sides. The cyclic operation of the steps in the escalator is used to convey passengers upward or downward at an inclined angle. The steps move horizontally at the passenger entrance, then gradually form steps, the steps gradually disappear near the exit, and the steps move horizontally again. After moving to the back, steps are gradually formed in the same way to complete a full cycle.

[0003] Currently, escalators are mostly used in places such as shopping malls and stations, where the flow of people is generally large. As people constantly step on the escalator, the dust and debris on their shoes adhere to the steps, resulting in the need for frequent cleaning of the escalator. During the operation of the downward escalator, the outer sidewall of the step and the horizontal plane will be exposed to the outside world at the same time, and a large amount of dust and debris will adhere to their surfaces. This makes it impossible for workers to quickly and effectively clean the outer sidewall of the step and the horizontal plane when the escalator is operating downward. Moreover, when manually cleaning the steps, it will also affect the use of the escalator by others. At the same time, there are grooves on the surface of the steps, making it impossible for workers to quickly and effectively clean the dust and debris stuck in the grooves of the steps moving downward.

[0004] Therefore, we provide an escalator with a step cleaning and disinfection function that does not affect the use of others. Summary of the Invention

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following descriptions, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0032] Embodiment 1

[0033] An escalator with the function of cleaning and disinfecting steps, as Figure 1 and Figure 2As shown in the figure, it includes an escalator 1, steps 101, a cleaning mechanism, a guiding mechanism, a flushing mechanism, a water removal mechanism and a reset mechanism. A number of steps 101 are rotatably arranged on the escalator 1. A number of grooves are provided on the horizontal plane of the steps 101, and the outer side wall of the steps 101 is arranged as an arc surface, and a number of grooves are also provided on the arc surface of the steps 101. A cleaning mechanism is provided below the escalator 1. The cleaning mechanism is used to scrape the grooves of the steps 101 to avoid dust and impurities remaining in the grooves of the steps 101, so as to achieve thorough cleaning of the steps 101. A guiding mechanism is arranged on the cleaning mechanism. The guiding mechanism is used to guide the movement of the cleaning mechanism so that the cleaning mechanism moves along the grooves of the steps 101. A flushing mechanism is arranged inside the cleaning mechanism. The flushing mechanism is used to flush the steps 101. A water removal mechanism is arranged on the upper part of the cleaning mechanism. The water removal mechanism is used to wipe and remove water from the flushed steps 101, and at the same time irradiate and disinfect the steps 101. A reset mechanism is arranged above the guide plate 201. The reset mechanism is used to reset the cleaning mechanism so that the cleaning mechanism cleans the horizontal plane of the steps 101.

[0034] The operator installs the device. At this time, the cleaning mechanism, the guiding mechanism and the water removal mechanism are in contact with the steps 101, and they always contact the surface of the steps 101 due to their own functions. Then the operator starts the escalator 1 and the flushing mechanism. The escalator 1 drives the steps 101 to rotate counterclockwise. The steps 101 will press the cleaning mechanism to rotate clockwise, so that the cleaning mechanism, the guiding mechanism, the flushing mechanism and the water removal mechanism work at the same time. The cleaning mechanism first moves on the outer side wall of the steps 101 and cleans it. Then the reset mechanism works, so that the cleaning mechanism moves on the horizontal plane of the steps 101 and cleans it.

[0035] In this process, the guiding mechanism first moves on the outer side wall of the steps 101, and then under the action of the parts inside itself, the guiding mechanism will move along the horizontal plane of the steps 101, so that the cleaning mechanism can accurately clean the grooves of the steps 101. At the same time, in this process, the flushing mechanism works. First, it flushes the outer side wall of the steps 101, so that too much dirty matter will not accumulate on the cleaning mechanism, resulting in incomplete cleaning of the cleaning mechanism. Then when the cleaning mechanism cleans the horizontal plane of the steps 101, the flushing mechanism will flush the horizontal plane of the steps 101. Finally, the water removal mechanism in this process works. First, it moves on the horizontal plane of the steps 101 and wipes and removes water from the flushed and cleaned horizontal plane of the steps 101. As the cleaning mechanism moves, the water removal mechanism will contact the outer side wall of the steps 101 to remove water. Finally, as the escalator 1 works, the above operations are repeated to clean the rotating steps 101 one by one.

[0042] As Figure 2 、 Figure 12 and Figure 13As shown in the figure, the reset mechanism includes a third fixing plate 7, a second sliding column 701, an L-shaped sliding plate 702, a sixth spring 703, a second rack 704, a second spur gear 705, and a protective shell 706. A third fixing plate 7 is fixedly connected between the lower parts of two first fixing blocks 202. Two second sliding columns 701 are slidably arranged in the third fixing plate 7. The left ends of the two second sliding columns 701 are fixedly connected with an L-shaped sliding plate 702. Two sixth springs 703 are fixedly connected between the L-shaped sliding plate 702 and the third fixing plate 7. The two sixth springs 703 are respectively sleeved on the two second sliding columns 701. Second racks 704 are fixedly connected to the front and rear side walls of the L-shaped sliding plate 702.

The two second spur gears 705 are respectively engaged with the two second racks 704.

The two second spur gears 705 and the two second racks 704 are respectively located in the two protective shells 706, which is used to reduce the contact between the cleaning liquid and the second spur gears 705 and the second racks 704, avoid rusting of the second spur gears 705 and the second racks 704, extend their service life. A chute is opened on the side wall of the protective shell 706. The first rotating shaft 203 is located in the chute of the protective shell 706.

[0043] When the cleaning mechanism works, starting from the Figure 2 state, as the step 101 rotates counterclockwise, the step 101 will squeeze the second fixing block 207 to the right. The second fixing block 207 is squeezed and twists clockwise around the first rotating shaft 203 through the connecting block 2061, the second rotating rod 205, and the first rotating rod 204. At the same time, as the second fixing block 207 twists, a relative rotation occurs between the second fixing block 207 and the second rotating rod 205, causing the first torsion spring 2062 to twist, so that the left surface of the second fixing block 207 is always in close contact with the right surface of the step 101. At the same time, as the step 101 rotates counterclockwise, a relative movement will occur between the second fixing block 207 and the step 101, causing the second scraper 210 to scrape the adhering substances in the grooves on the outer side wall of the step 101. At the same time, under the action of the third spring 211, the second scraper 210 will be in close contact with the groove of the step 101 to achieve a better cleaning effect.

[0044] When the second fixed block 207 is squeezed and twisted clockwise, the second fixed block 207 drives the first rotating shaft 203 to rotate clockwise through the connecting block 2061, the second rotating rod 205 and the first rotating rod 204. The clockwise rotation of the first rotating shaft 203 will drive the second rack 704 to move to the right through the second spur gear 705. Here, the upper part of the protective case 706 is arranged in a triangular shape to prevent the cleaning liquid in the flushing mechanism from pouring directly onto the second spur gear 705 and the second rack 704, which may cause the second spur gear 705 and the second rack 704 to rust and affect their normal operation. The second rack 704 drives the L-shaped sliding plate 702 and the second sliding column 701 to move to the right and compresses the sixth spring 703. As the relative movement between the second fixed block 207 and the step 101 occurs, the second scraper 210 will complete the cleaning of the outer wall of the step 101. At this time, the step 101 will release the restriction on the second fixed block 207. Under the action of the sixth spring 703, the L-shaped sliding plate 702 will drive the first rotating shaft 203 to rotate counterclockwise through the second rack 704 and the sixth spring 703. The counterclockwise rotation of the first rotating shaft 203 drives the second fixed block 207 to move quickly to the left through the first rotating rod 204, the second rotating rod 205 and the connecting block 2061. When the second fixed block 207 moves quickly to the left, it will contact the horizontal plane of the step 101. As the second fixed block 207 moves to the left, the second fixed block 207 will drive the second rotating rod 205 to twist through the connecting block 2061. The twisting of the second rotating rod 205 will first move downward to compress the first spring 206 and then move upward to return to the initial state. During this process, the leftward movement of the second fixed block 207 will cause the first scraper 208 to scrape the attached substances in the horizontal groove of the step 101. Under the action of the second spring 209, the first scraper 208 will be in close contact with the horizontal plane of the step 101 to ensure thorough cleaning of the horizontal plane of the step 101.

[0045] During the operation of the cleaning mechanism, the guiding mechanism will work synchronously. Under the action of the second torsion spring 302, the second rotating shaft 301 drives the third rotating rod 303 and the parts thereon to rotate clockwise together, so that the guide wheel 308 is in close contact with the groove of the step 101, starting from Figure 2 this state. As the step 101 rotates counterclockwise, relative movement occurs between the guide wheel 308 and the step 101. When the guide wheel 308 passes through the outer wall of the step 101, similarly under the action of the second torsion spring 302, the guide wheel 308 rotates counterclockwise to contact the horizontal plane of the step 101. At this time, the contact of the outer wall of the step 101 releases the restriction on the guide wheel 308.

[0046] Then the step 101 continues to rotate counterclockwise. At this time, under the action of the second torsion spring 302, the second rotating shaft 301 drives the third rotating rod 303 and the parts thereon to rotate clockwise. When the third rotating rod 303 rotates clockwise to make the limiting rod 404 vertical, under the action of the fourth spring 307, the bent cylindrical rod 306 will move downward, and the downward movement of the bent cylindrical rod 306 will drive the first rack 402 to move downward through the guide frame 4. The downward movement of the first rack 402 drives the first spur gear 403 to rotate clockwise, and the first spur gear 403 drives the fourth rotating rod 305 to rotate clockwise. At this time, under the action of the arc surface of the fourth rotating rod 305, the fourth rotating rod 305 will squeeze the limiting rod 404 to move upward, so that the upper part of the limiting rod 404 extends into the blind hole of the third fixing block 3, realizing the limit fixation of the third fixing block 3 and the third rotating rod 303. Subsequently, after the fourth spring 307 returns from the compressed state to the initial state, at this time, under the action of the third fixing block 3, the third rotating rod 303, the fourth rotating rod 305, the bent cylindrical rod 306 and the guide wheel 308, the upper surface of the second fixing block 207 is parallel to the horizontal plane of the step 101.

[0047] Next, the second fixed block 207 will move leftward to clean the horizontal plane of the step 101, enabling the first scraper 208 to enter the groove on the horizontal plane of the step 101. At this time, since the upper part of the limit rod 404 extends into the blind hole of the third fixed block 3, the guide wheel 308 will not be able to rotate. However, at this time, the guide wheel 308 still contacts the horizontal plane of the step 101 and moves thereon. As the second fixed block 207 performs the above-mentioned movement, the guide wheel 308 will touch and press against the outer side wall of the step 101. Since the outer side wall of the step 101 is arranged as an arc surface, the guide wheel 308 cannot move along the outer side wall of the step 101. When the guide wheel 308 touches and presses against the outer side wall of the step 101, the guide wheel 308 will drive the bent cylindrical rod 306 to move rightward to compress the fourth spring 307. The rightward movement of the bent cylindrical rod 306 will drive the first rack 402 to move rightward through the guide frame 4. The rightward movement of the first rack 402 will drive the first spur gear 403 and the parts connected thereto to rotate counterclockwise together. Eventually, the guide wheel 308 will perform a torsional movement on the outer side wall of the step 101. At the same time, the first spur gear 403 drives the fourth rotating rod 305 to rotate counterclockwise. Affected by the arc surface of the fourth rotating rod 305, the arc surface of the fourth rotating rod 305 will gradually release the restriction on the limit rod 404. Under the action of the fifth spring 405, the limit rod 404 moves rightward and moves out of the blind hole of the third fixed block 3, releasing the restriction between the third fixed block 3 and the third rotating rod 303. Since the guide wheel 308 has already undergone torsion on the outer side wall of the step 101, when the second fixed block 207 moves leftward, the guide wheel 308 will drive the third rotating rod 303 and the second rotating shaft 301 to rotate counterclockwise through the bent cylindrical rod 306, the fourth rotating rod 305, the third rotating shaft 304, and the fourth rotating shaft 3041. The counterclockwise rotation of the second rotating shaft 301 will cause the second torsion spring 302 to undergo further torsion. The subsequent work will repeat the above movement process.

[0048] During the working process of the cleaning mechanism, the flushing mechanism will work synchronously. Starting from Figure 2 this state, at this time, the n-shaped sliding rod 613 contacts the side surface of the step 101. Under the action of the step 101, the n-shaped sliding rod 613 moves rightward to stretch the first tension spring 614. Subsequently, under the action of the fourth torsion spring 604, the bent rotating rod 603 rotates clockwise. The bent rotating rod 603 drives the rotating shell 601 to rotate clockwise, making the rear cylindrical hole 602 communicate with the first conduit 605. At this time, the front cylindrical hole 602 is facing the right side wall of the housing 6. The small water pump at the end of the hose works to pump the cleaning liquid from the liquid storage tank 610 to the liquid inlet 609. The cleaning liquid enters the housing 6 through the liquid inlet 609, then enters the first conduit 605 through the rear cylindrical hole 602, and then flows into the first spray pipe 606 from the first conduit 605 and sprays out, so that the cleaning liquid flushes the groove on the outer side wall of the step 101.

[0049] As the step 101 rotates, when the second fixed block 207 moves to the horizontal plane of the step 101, the restriction of the n-shaped slide bar 613 by the step 101 is released at this time. Under the action of the first tension spring 614, the n-shaped slide bar 613 moves leftward to squeeze and bend the rotating rod 603. The bent rotating rod 603 rotates counterclockwise under the extrusion, and at the same time, the fourth torsion spring 604 is twisted. The bent rotating rod 603 drives the rotating shell 601 to rotate counterclockwise, so that the front cylindrical hole 602 communicates with the second conduit 607. At this time, the rear cylindrical hole 602 faces the right side wall of the housing 6. The cleaning liquid will flow through the second conduit 607 through the rear cylindrical hole 602 and be sprayed out from the second nozzle 608, so that the cleaning liquid flushes the grooves on the horizontal plane of the step 101. The flushed cleaning liquid falls on the guide plate 201 through the surface of the step 101. Under the action of the support frame 2, the splashing of the dropped cleaning liquid is avoided.

[0050] During the operation of the cleaning mechanism, the water removal mechanism will work synchronously. Starting from Figure 2 this state, then the escalator 1 operates. Under the action of the third torsion spring 502, the fifth rotating shaft 501 rotates counterclockwise. The fifth rotating shaft 501 drives the runner 505 to rotate counterclockwise through the U-shaped rod 503 and the n-shaped fixing frame 504, so that the runner 505 clings to the surface of the step 101. As the step 101 rotates counterclockwise, the runner 505 will rotate clockwise on the step 101. At the same time, a relative displacement occurs between the runner 505 and the step 101. The clockwise rotation of the runner 505 will perform the water removal work on the surface of the step 101, so that the cotton-like line of the runner 505 adsorbs the residual water droplets on the surface of the step 101.

[0051] At the same time, under the action of the second tension spring 509, the second fixing plate 508 drives the sliding block 506 to move upward through the first sliding column 507 to be in close contact with the runner 505. As the runner 505 rotates clockwise, the runner 505 after adsorbing water droplets will pass through the sliding block 506. Under the extrusion of the sliding block 506, the cleaning liquid in the cotton-like line of the runner 505 will be extruded. Due to the existence of the limiting plate 510, the cleaning liquid will fall onto the upper surface of the guide plate 201 through the inclined surface of the n-shaped fixing frame 504. Due to the inclined setting of the guide plate 201 and the arc surface of the guide plate 201, the extruded cleaning liquid flows into the collection box 611 through the guide plate 201. At the same time, the ultraviolet lamp 511 works to irradiate and disinfect the surface of the step 101 during this process.
